Description

The invention relates to the construction, and, in particular, to equipment for concreting beams of span structures of reinforced concrete bridges.

A known apparatus for the manufacture of reinforced concrete products, comprising outer side and top shields, a pallet with pivotal hinges and screw struts ll.

However, in this opa.7: the casing, when opening the outer panels, there is no space for the passage of the service personnel, and therefore the installation work on the installation of the frame is difficult.

Closest to the present invention is an installation for the manufacture of reinforced concrete products of superstructures, comprising a base plate mounted on a base, movable outer form panels and mechanisms for displacing boards 2.

A disadvantage of the known installation is low productivity. In addition, the control of the finished product — the quality of concreting before transferring the stress of reinforced reinforcement to concrete and the removal of the beam from the pallet is impossible.

The aim of the invention is to increase productivity and improve

operational features of the installation.

The goal is achieved by the fact that the installation for the manufacture of reinforced concrete products of superstructures, comprising a base plate mounted on the basement, movable outer form panels and mechanisms for developing formwork panels, is equipped with carriages, inclined guides for moving these carriages and racks located along the longitudinal outer form panels. , the longitudinal boards of the external formwork are installed on the carriages and guiding the bases, while the mechanisms for moving the boards of the external formwork are made in form, power cylinders, and racks are connected in the upper part with 20 external formwork panels and with the base by means of hinges.

In addition, in order to be able to manufacture products of various p25, fil, v1;

Claims (2)

FIG. 1 shows an installation for the manufacture of reinforced concrete products of span structures; 2, then 30, in the expanded state. The installation consists of a concrete base, on which the pallet 1, inclined guides 2 and support shoes 3 are installed. In the inclined guides 2. Carriages 4 of the limiting stops 5 of the carriage 4 movement are installed. Carriages 4 trans. are placed by the power cylinders 7. Stands 8 are mounted on support shoes 3 by means of hinges 9. In the upper part, brackets 6 of formwork are attached to brackets 10 of racks 8 by means of hinges 11. In the upper part of the installation, a removable shaping element 12 is mounted, which consists of a U-shaped frame 13, rotatable shields 14 and straps 15. The disassembling of the shields is carried out as follows. The shaping element 12 is removed by rotating the shields 14 when the strings 15 are unwound. The force cylinders 7 tons chute by moving the carriages 4 along the inclined guides 2 to the stops 5 Racks 8 turn in the upper hinges 9 and rotate on the hinges 11 of the brackets 10. When This results in a close to parallel transfer of the longitudinal side shields of the hull of the sheath and the formation of passages between the open shields and the concrete beam. The assembly of the device is carried out in reverse order by moving the carriages 4 and the uprights 8 along the guides 3 using the force cylinders 7 to the position of the shields b, corresponding to the shape of the concrete beam. The design allows to create passages up to 1 m wide, sufficient for operation of the service personnel, for example, for 23.6 m long reinforced concrete beams. Providing the passage allows controlling the process of frame assembly, tension of reinforcement beams, installation of technological parts on the frame before concreting and correcting possible defects before the tension, reinforcement will be transferred to the concrete of the manufactured beam. Claim 1. An installation for the manufacture of reinforced concrete products of span structures, comprising a base plate mounted on the base, movable outer form boards and mechanisms for moving the boards, formwork, characterized in that, in order to increase productivity and improve the operational capabilities of the installation, it is equipped with slides guides for the movement of these carriages and racks located along the outer form boards, and the outer floor form boards mounted on the carriages, and ravel cadie — on the base; herewith, the mechanisms for moving the boards of the external formwork are made in the form of power cylinders, and the racks are connected in the upper part with the boards of the external formwork and with the base by means of hinges. 2. The installation according to claim 1, in which it is provided with a removable forming element. Sources of information taken into account during the examination 1.
