Bricks "Lego": reviews, composition. Manufacture of bricks "Lego"

Such a modern construction material as"Lego" - brick, the reviews of which speak of its excellent quality, is an example of that simple and ingenious solution. This product has some improvements over conventional brick. In the first half of the twentieth century, the Danish construction worker Ole Kirk decided to make a brick with a definitely new shape. Namely with such that the received product itself helped to stack. So it was created "Lego" - a brick, the reviews of which are received from professionals in the construction sector, indicate its reliability and convenience of working with it. About this and not only further read more.

Product Description

Bricks "Lego", reviews of which speak aboutefficiency and usability of this material, have two convex spherical holes on their upper surface. Get the brick on a certain machine. The lower plane of the product is equipped with two holes with a sphere concave. This is a characteristic feature of such products as "Lego" bricks, the reviews of which point to the high practicality of the material. The presence of such a geometry provides a clear fixation of this product during construction work. Docking of elements is carried out with the help of a glutinous solution. The geometric dimensions of the finished product are:

• length - 250 mm;
• width - 125 mm;
• height - 45-80 mm;
• weight - 3,5-4 kg (depends on the components included in the product);
• the maximum withstand pressure is 300 kg / cm².

Bricks "Lego": the composition of the mixture

In this regard, there are several varieties. Brick "Lego" can be made from the following compounds:

• Clay-cement. Here, components such as clay (90%), cement (8%) and water are used.
• Composition based on different screenings. It also includes screenings (85-90%), cement (8%) and water.
• Clay-sandy. This includes four components: sand (35%), clay (55%), cement (8%) and water.

When planning production, it is necessary to take into accountavailability of raw materials. This is an important condition. Bricks, which are obtained by the press method, require the presence of raw materials with a fine fraction. This should be taken into account to achieve the necessary strength. Brick "Lego", obtained from screenings, has the highest strength characteristics.

The content in the production of a large amount of sand contributes to the deterioration of the strength index due to the fact that there are large sand fractions.

The production of such products as "Lego" bricks,reviews about which indicate their reliability and effectiveness, requires the presence of special mold matrices. With their help, a surface is created with the necessary smoothness and with certain parameters of given geometric dimensions. For a full-fledged production of this product, you should have the whole set of matrices that allow you to get half of these bricks and fitting products. They are used for finishing works.

Description of the equipment

To make bricks "Lego", reviews about whichpoint to the practicality and simplicity of their use, it is necessary to have an appropriate machine. In its construction include units of a certain category, which are mounted on a metal frame. For example, equipment such as Legostanok provides an opportunity in a semi-automatic mode to produce bricks "Lego", the composition of the mixture for manufacturing which is specified above. This product is obtained in this unit by pressing method at high pressure. In this case, the subsequent firing of the product in the thermocouple is not carried out. With this machine, it is possible to make bricks "Lego" with their own hands.

Operating principle

In this case, certain actions are taken into account. The mixture prepared for the formation of bricks is covered in a specially adapted bunker. Then, with the aid of a dispenser, it enters the molding compartment. Then the mixture is compressed with a hydraulic press under high pressure. As a result, you get a ready-made "Lego" brick. Equipment, reviews of which are positive due to the simplicity in the implementation of the workflow, as mentioned above, is considered using the example of the Legostanok machine. It has a three-phase electric motor and an oil pump, which creates the necessary pressure in the hydraulic cylinder. Thanks to the mechanized action of compression, this machine provides high pressure and increased process productivity. Its presence will allow to produce bricks "Lego" with their own hands even without special skills and experience.

Equipment parameters of this type areoptimal for placing it on a site of a limited area. With proper organization of labor and the mixture preparation process ensures achievement of high results.

The main units of the machine are certain aggregates:

1. Loading hopper.
2. Dosing mixer with manual drive.
3. Molding chamber.
4. Matrix. With its help, a certain geometry of the holes of the "Lego" brick is given. It is located in a molding chamber.
5. Electric motor.
6. Oil pump.
7. Hydraulic Press. It works on the oil, which pumps the pump.
8. Machine bed.

Description of the workflow

The specified machine for the production of bricksIt can function both in semi-automatic mode and in manual mode. Everything depends on the chosen technology. By manual mode is meant a molding process using a lever-type mechanism. He is able to create the necessary force in the press sole.

With semi-automatic operation, the operatoropens the valve at the required moment on the hydraulic line, and the molding is carried out using a hydraulic press. This mode contributes to improving the performance of equipment in the range of 1.5-2 times. These functions have the above machine. "Lego" is a brick, the reviews about which are positive because of the reliability and efficiency of the material, while getting better. The reason is that the required pressure is achieved for effective coupling of the mixture at the molecular level.

Brick production technology "Lego"

The process of manufacturing this product includes several stages. Namely holding:

• preparatory works;
• molding;
• pressing bricks;
• warehousing of finished products with appropriate exposure for a certain time.

Next, consider each stage in more detail. Preparatory works include carrying out the delivery of the required raw material, sorting it and preparing the required mixture for molding. To increase productivity, it is recommended to use additional equipment that will allow the components to be brought to the necessary fraction (if necessary) by the sieving method and to mix the additives of the raw material. In the presence of large volumes, the finished mixture is conveyed to the receiving bin of the equipment by means of a conveyor. Then, with the dispenser, the necessary volume of material is sent to the matrix to form. This is done automatically with the help of the operator. After that, the dispenser returns to the space below the bunker. Then, a valve is opened, which supplies the oil to the press. After this, the mixture is compressed for a certain time. Then, with the help of the ejector, the finished brick is extended and transferred to the temporary storage site, where the products obtained must be kept for three days. After this, the product can be shipped to the consumer. The time interval before the application of the product should be at least 21 days.

Recommendations

1. In order to maximize the productivity of the machine, two people should be involved in the production process and carry out the automation of the preparatory work.
2. The receipt of finished products can be carried out with the help of one operator. This will significantly increase the time for the production of a certain number of bricks.
3. The receipt of quality products directly depends on the components used and their dosage in the mixture. The necessary indicators in each specific case can be achieved empirically.
4. To ensure permanent orders,use a semi-automatic machine. As a result, the pressure in the forming process will increase. This, in turn, will lead to the possibility of getting quality and accurate externally bricks "Lego", the composition of the mixtures for which is indicated above.

Application area

Brick "Lego" is a product of the newest generation withincreased density and a special form. This product has improved technical characteristics. Bricks "Lego" in comparison with the usual "fellow" provide an ideal appearance of the facades of various buildings for many years. Also, the water absorption of this product is only 5%. As a result, a wall built of bricks "Lego" will not absorb moisture and various dirt. This product is quickly cleaned with water. Also, the products have high frost resistance, is environmentally friendly and suitable for use in different climatic conditions.

The scope of the "Lego" brick was originallyIt is determined by its ability to maintain an ideal appearance for a long time. Therefore, it is often used for facing various structures, as well as for interior finishing. However, from the brick "Lego" it is possible to perform all the wall structures, especially when using foam concrete as a filler.

How to work with a brick "Lego"?

One of the main advantages of working with sucha product like a brick "Lego", is the simplicity of its styling. Compared to the "classical" analogue, editing will not cause any difficulties. Possessing a special shape and having two guide holes, the "Lego" brick fits quite simply:

1. It will be sufficient to mount onlyThe first row using the level and guides. This is also no complication. Then the rest of the rows are aligned themselves during the laying process, thanks to the corresponding guides.
2. For installation, a minimum amount of adhesive is required. Bricks "Lego" fit perfectly with each other. As a result, for 500 pieces, glue does not exceed 25 kilograms.
3. Even an inexperienced master canan ideal bandaging of the joints, since the installation of the Lego brick on the guides completely eliminates the presence of traditional errors. The stacking speed is higher by 2-3 times in comparison with the usual analog.

Possessing low water absorption and high density, the "Lego" bricks are not afraid of pollution. If excess glue leaves the edges of the joint, they can be easily removed with a spatula after full drying.

Since the masonry, when erectedused bricks "Lego", has through holes throughout the height, it is very convenient to conduct reinforcement. If it is planned to erect buildings of low (for example, fence elements), the installation can be carried out generally without glue or mortar. Bricks "Leg" laid out "on a dry", and then in the holes of the masonry put in the reinforcement, which has a diameter of 10-20 mm, and fill with cement. As a consequence, the strength of the masonry is increased, and also the stability and reliability of the wall geometry is ensured. It should be taken into account that the pouring should be carried out in stages, that is, no more than 6 rows per 1 call.

It is convenient to use holes for the laying of utility networks. The presence of cavities in the walls is excellent for this. Then you can fill the holes with concrete.

Eventually

Currently, the bricks "Lego" are consideredas a new generation material. They are still treated with interest and suspicion. But increasingly, "Lego" (brick) reviews of builders receive a positive nature because of the quality of the material and ease of laying, as well as favorable prices, practicality and impeccable appearance. And these are pretty strong arguments.
