Description

with

The invention relates to the manufacture of building products and structures, in particular, to technological lines and cassette-conveyor-type installations for forming interior wall and ceiling panels.

The purpose of the invention is to improve the quality of products by eliminating early demolding and overloading and intensifying vibration.

Figure 1 shows a line for the manufacture of flat concrete products, a plan view; figure 2 - section aa in Fig, 1; on fig.Z - section B. B. Figure, 1.

The line for the manufacture of flat concrete products contains a package of heat shields 1, forming a movable rigid duct, permanently mounted on the base 2 by means of elastic elements 3 wedge forms 4 to form

wedge in a vertical plane. On the base 2 between the molds 4, mechanisms 5 are installed for assembling and demoulding in the form of articulated levers 6 with rollers 7. The actuator for rotating the levers 6 can be, for example, a power cylinder 8 hinged between the levers 6.

The stationary wedge molds 4 are arranged in pairs coaxially at the inlet and outlet of the roller table 9. On the base 2, there is also installed an actuator 10 for horizontal movement of the disassembled duct from thermal panels 1 along the roller table 9, for example, in the form of an electric winch. Stationary wedge molds 4 have permanent steam and power supply systems with disconnecting devices {valves and switches) and are equipped with vibration exciters 11, for example, in the form of a longitudinal form 4 fixed inside the heat shield to

shaft with unbalances driven by an electric motor, built-in or taken out of the form.

Technological line works as follows.

At the initial moment of time, the package of heat shields 1 is on the upper (see Fig. 1) block of wedge forms 4, and by this time they have completed a full cycle of heat treatment of products, which lasted for the entire 3rd non-working shift. The lower wedge molds were prepared to continue the process (successively, with the help of an overhead crane, the products were dismantled, double-sided forms were cleaned and lubricated, and reinforcement was made).

The package of heat shields 1 is pressed out under the influence of the decoupling mechanism 5. This is carried out by pulling the rods of the power cylinders 8, which, turning the arms 6 with the roller coils 7, raise the latter until they come into contact with the supporting surfaces of the heat shields 1. Subsequently when driving the rod of the power cylinder 8, the roller pores 7 squeeze up the package of shields 1 to the level of the roller table 9. In this case, the package 1 passes the point of maximum lifting and after passing the vertical levers 6 on the base 2 with the aid of the stop. Since wedge molds 4 with molded products are fixedly fixed on base 2, when lifting the shields 1, the products are dismantled. Further, with the aid of the actuator 10, the decalcified package of shields 1 is moved along the rollers of the levers 6 and the roller table 9 to an intermediate position between the blocks of wedge molds, where it is cleaned and lubricated. Next, the package of shields 1 moves to the lower (see Fig. 1) wedge forms 4. Thus, it is located on the roller-supports 7 between the wedge forms 4 prepared for operation, but slightly higher, with gaps from the latter.

Pressing the package of shields 1 onto wedge forms 4 is performed under its own weight when extending the rods of the power cylinders 8, as a result of which the levers 6 with the rollers 7 turn, fall down and come out of contact with the supporting surfaces of the package shields 1, since the latter only descend before jamming on the molds 4. Thus, a package of heat shields 1, hung on the block of wedge molds 4, supported on the base 2 by means of elastic elements 3, i.e. having the opportunity to perform oscillatory movements under the influence of vibration from vibration exciters 11. A thermal shield unit is connected to the steam supply system. Next, the concrete is laid, vibrated and then heat treated on a full cycle, after which the cycle of the production line is repeated.

Thus, all operations are carried out by the shuttle method, while, while one block of the wedge molds is being prepared for molding, concrete is placed on another block with movable heat baths, followed by heat treatment.
