Abstract

The invention relates to the manufacture of reinforced concrete bulk blocks for residential and public buildings. The purpose of the invention is to reduce energy consumption and material consumption. During the molding of reinforced concrete bulk blocks, the forming surfaces are lubricated, the forming plates are installed on the core and the inner surfaces of the outer shields: on the core to form a U-shaped shell and on the outer shields to form a duct. After installing the core and outer shields, the block is concreted into its working position. The stripping is carried out after concreting by diluting the outer shields and withdrawing the core. Then heat treatment is carried out. The forming plates are separated from the bulk block after heat treatment. 26 il.

The invention relates to the manufacture of reinforced concrete bulk blocks used in the construction industry of a bulk block house building, and can be used in universal and conventional molding plants for the manufacture of reinforced concrete bulk blocks such as a bell, recumbent cup and cup as prefabricated elements of block rooms. factory made for residential and public buildings.

The purpose of the invention is to reduce energy consumption and material consumption.

Fig. 1 shows an installation for forming volumetric blocks with a concreted volumetric block in shells made from forming plates that are encased with shields and a core according to the proposed method, a section, side view; figure 2 is the same, the view in the plan; on fig.Z - the same, rear view; in Fig. A - section A-A in Fig. 1; in Fig. 5, the process of forming a volumetric block of the cap type is set up, the shells are installed from the forming plates on the outer shields and the core; figure 6 is the same, the installation of the core on the outer panels with shells from the forming plates in the working position; in Fig.7 the same, in the initial moment-concreting; 8 - the same, at the final moment - concreting; Fig. 9 is the same, preliminary external demolding with rolling of the product with shells of forming plates on the core; figure 10 is the same, pre-internal demolding; figure 11 is a section bB in figure 10; Fig. 12 shows the technological operation of the process of separate molding the floor and wall slabs into a single monolith of a recumbent block of the recumbent glass type, "

from the forming plates on external boards and the core; on Fig the same, the installation of the core and outer shields with shells of the forming plates in the working position; figure 1 - the same, at the initial moment-concreting; on Fig - section B-R in Fig.14; on Fig - the same, in the final moment-concreting; in Fig. 17, the same is a preliminary outer sheeting with the product rolling out with shells from the forming plates; on Fig - the same pre-internal demolding; on FIG. 19 - section G-D in FIG. 18; Fig. 20 shows the technological operation of the process of separate molding the floor and wall slabs into a single monolith of a volumetric block such as a glass, installing the shells from the forming plates on the outer shields and the core; on Fig - the same, the installation of the nickname and the outer shields with shells of the forming plates in the working position; on Fig - the same, concreting; on Fig.23 - section dD in Fig.22; in fig .. - the same, preliminary internal demolding; Fig. 25 is the same, preliminary external demolding with the product rolling out with shells from the forming Plates; on Fig.26 section EE of Fig.25.

The installation for forming bulk blocks consists of adjustable shells 1 of the forming plates mounted on the core 2, mounted on the pallet 3, external boards supported on the sliding supports 5 also provided with the shells 1 of the forming plates. The core 2 with the pallet is mounted on the lifting device 6. Above the installation is placed a bunker 7 with a concrete mix.

The method is carried out as follows.

The surfaces of the forming plates of the adjustable shells 1 are cleaned and lubricated, followed by their installation on the core 2 and the outer shields, for example by passing the plates through steel brush shafts during their rotation and lubrication bath. Movable shells from the forming plates are installed on the core 2 in a vertical position with the support on the grooves of the pallet 3 and in a horizontal position on the ceiling of the core 2, fastened them in separate places by known devices, for example, snapping rods or screws. Then, the adjustable shells 1 are mounted on the outer shields k in a vertical position with the support on the extendable supports 5, for example hydraulically extended shelves with a lever clip at the end, and fasten them. Then reinforcement is made. At the core 2 wear ready volume spatial reinforcement cage surround unit known methods. The core 2 is rolled into the space between the outer
