Description

A device is known for erecting, for example, a weir of dams, comprising a formwork shield and a force mechanism mounted on the supporting frame for setting the shield to the design position.

However, when using the known device in the constructions of an extended nature, the deflections of the beams occur, which leads to the formation of flows between the Rus.

The purpose of the invention is to prevent the formation of flows between the Rus.

This is achieved by the fact that in the proposed device the shield is fixed with a deflection towards the concreted surface on a supporting frame made in the form of interconnected longitudinal upper and lower beams, at the ends of which the support collars are installed, fitted in the lower part with brackets for connecting with guides, which are fixed to the anchors, embedded in the laid concrete of the lower rus, and at the bottom of each support cage between its body and the supporting frame are placed the power mechanisms for installing the shield in the design position.

In addition, in such a device, compensators are installed between the upper support beam and the rail.

FIG. 1 shows a device in plan; in fig. 2 is a section along A-A in FIG. one; on

FIG. 3 shows a section along B - B in FIG. one; in fig. 4 is a section along BB in FIG. 3

The formwork panel 1 is fixed on the supporting beams 2 with deflection in the direction of concreted

surface by means of gaskets 3 of different thickness. The carrier beams are connected by links 4, the free ends of the beams enter the through windows 5 of the support sleeves 6.

Supporting cage made in the form of boxes

with through windows 7 and provided with locks 8, anchors 9 protruding beyond the concrete, and supporting platforms 10 for mounting the rails 11. The supporting sleeves in the lower part have brackets 12 for connecting with the rails. Between the upper carrier beam, which interacts with the force mechanisms 13 and the guide, compensators 14 are installed, which are made in the form of elastic elements. In the lower part of the device there is a power mechanism (jack) 15. In addition, the device is equipped with axles 16, on which rollers 17 are located, and in the upper part - a spring-loaded safety device 18.

The device works as follows.

Anchors 9 are laid in the concrete massif and guides 11 are bolted to their supporting platforms 10. The shuttering board 1 with supporting beams 2 and supporting

sleeves 6 at the ends and staples 12 are installed on the guides 11, the input of the catcher 18 into the grooves of the guides. The support sleeves 6 are secured to the anchors 9 with clamps 8. Correcting force mechanisms 13 place the top of the formwork shield 1 along the marks and a compensator 14 is inserted between the upper support beam 2 and the guides 11. With the help of the force mechanism 13 they extend the upper support beam, lifting it this bearing clips. The lower part of the formwork panel 1 is supported by a bottom-row beta, while the expansion of the force mechanisms 15 pre-strains the lower carrier beam 2 by straightening the curbing of the formwork panel to the straight edge of the bottom line while the curtain-line of the formwork board is fitted. After selecting the elevators of the lower support sleeves and checking the position of the device relative to the marks of the erected structure, proceed to filling it with concrete. After a load is applied from the concrete mix of the upper tier, the upper part of the curvature is selected due to the pressure of the concrete mix; in the lower part, the prestressing forces and the force of the concrete mix are replaced, with the result that a straight surface is obtained in the upper part, and the concrete does not flow between the ends in the lower part.

At the end of the concreting, the device is rearranged. At the same time, corrective and clamping force mechanisms are weakened.

and 15; and the supporting sleeves 2 with rollers 17 are pressed against the guides I. The clamps 8 are taken out and the formwork shield 1 is retracted by power mechanisms 13 and 15. The device is rearranged on the rollers 17 along the guides 11.
