(54) METHOD OF MANUFACTURING WALL BLOCKS

one

The invention relates to the construction and can be used in the manufacture of prefabricated large-sized wall structures.

A known method for the manufacture of prestressed large wall blocks of a composite structure of middle blocks consists of laying a number of component blocks, pouring joints between them with masonry, and prestressing the longitudinal reinforcement.

During the manufacturing period, prefabricated wall blocks are pre-compressed with a load applied symmetrically to their plane, after which the prestressing of the longitudinal reinforcement is performed with the preloading of the composite block and thereafter the preliminary reduction is removed 1.

However, in connection with the operation of the lower and upper bending lines, the bending is made from solid middle blocks with a length of the entire width of the prefabricated block, which limits the width of the produced (Prefabricated wall reinforced blocks and their weight, as well as reduces labor productivity.

Closest to the invention is a method for producing wall blocks by making a monolithic wall and cutting it into blocks. This method was developed for the production of products from cellular concrete G23.

The purpose of the invention is to expand the field of application of the method for the manufacture of composite reinforced blocks.

The goal is achieved in that according to the method of making wall blocks by making a monolithic wall and cutting it into blocks, a monolithic wall is formed by masonry with displaced seams of piece elements with a thickness equal to the wall thickness, and the surface of each row of the wall is milled before before cutting the wall into blocks, cords are drilled from bottom to top and reinforcement is placed in the latter.

The proposed method of making blocks allows it to be carried out without pre-calibrating the component blocks, and the block size by width is provided by cutting the resulting wall. The use of an adhesive compound (in combination) with vertical reinforcement increases their transportability and, in general, labor productivity. Figure 1 shows the stacking of a series of constituting elements of the blocks ;; figure 2 - milling the plane of contact; figure 3 - drilling holes; figure 4 - cut myolite wall into blocks. The method is carried out as follows. On the fixed platform 1, a row of blocks 2, whose width is equal to the thickness of the wall, is laid down and fixed, after the first stage, the upper contact surface of the row of blocks is milled. Adhesive, for example, a cement colloidal glue, is applied onto the processed and dedusted surfaces with a cutting tool 3 and another row of blocks is laid. Moreover, the laying of the next row of blocks is performed with the displacement of the individual blocks of the row along its axis by an amount equal to 1/2 the size of the entire block. Thus, the bindings of the adjacent rows of blocks are provided. A series of blocks are laid until the desired height of the large block is achieved. In the received wall, vertical holes are drilled at the rate of two for one wall block. The drilling is carried out using a drilling tool located on the movable carriage 4. The cart is moved along the bottom of a trench along the axis of the platform. Reinforcement elements are installed in the bore-holes with which the walls are pressed. Next, the sawing of the obtained wall is carried out into large wall blocks 5 with a width and height corresponding to the width and height of a large block. From the platform, large wall blocks are removed with a lifting mechanism using reinforcing elements located in bore-holes. The advantage of the proposed method lies in the fact that large wall blocks are made by the group method. At the same time, their manufacture is carried out without preliminary calibration of the dying blocks, and the block sizes in width are provided by cutting the resulting bent. The use of the adhesive composition in combination with vertical reinforcement and compression of the blocks greatly increases their transportability and overall productivity. In addition, the proposed method allows the blocks to be shipped to the consumer without additional exposure. Surfact of the Invention The method of making wall blocks by making a monolithic wall and cutting it into blocks, characterized in that, in order to expand the field of application for the manufacture of composite reinforced blocks, the monolithic wall is formed by masonry with displaced joints from piece elements with a width equal to the side of the wall, Moreover, the surface of each row of laying is cut before milling, and before cutting the wall, blocks are drilled from bottom to top and ai taTypy is placed into the blocks.
