Abstract

Use: in construction for the erection of walls of reinforced concrete. SUMMARY OF THE INVENTION: The frame is hingedly connected by brackets to shields and corner formwork elements. Structural rigidity is provided by making steps on the brackets on which the frame is placed. 2 Il.

Description

The invention relates to the construction and can be used for the construction of walls of monolithic reinforced concrete.

A block formwork is known, including a frame pivotally connected to shields and corner elements.

Closest to the invention of the technical essence and the achieved result is block formwork comprising a frame, boards with brackets and corner formwork elements.

However, the disadvantage of this construction is the high labor intensity of the formwork work due to the considerable form removal effort.

The aim of the invention is to reduce the labor intensity of the formwork work.

To do this, in the block formwork, including the frame, corner formwork elements and boards with brackets, the frame is pivotally connected to the boards and corner formwork elements and freely mounted on the brackets by means of ledges made on them, and the center-to-center distance of the hinges connecting the frame with corner pieces formwork elements, less than the center distance of the hinges connecting the frame with the shields, while the shields are overlapped with the corner formwork elements.

Figure 1 shows block formwork; Fig. 2 shows articulated joints of a frame with an angle formwork element and a shield (node I in Fig. 1).

The block formwork contains frame 1, corner shuttering elements 2 and shields 3 with brackets 4 welded to them. Shields 3 with corner shuttering elements 2 are overlapped, with shields 3 mounted outside of the corner shuttering elements 2. The frame 1 is connected with hinges 5 and 6 to shields 3 and corner shuttering elements 2, with the center-to-center distance of the hinges 5 connecting the frame 1 with the corner shuttering elements 2 less than the center-to-center distance of the hinges 6 connecting the frame 1 with the shields 3. The brackets 4 have a guide with scythe with ledge 7. The frame 1 is freely mounted on the ledges 7 brackets 4.

Boards 3 are equipped with mounting loops 8, and frame 1 with mounting loops 9.

Block formwork works as follows.

For wall covering, the formwork is mounted on a base made, such as a slab. For this, the formwork is lifted by means of a lifting device, such as a crane, for the mounting loops 8 of the shields 3 to the base. At the same time, the angular shuttering elements 2 hang on the hinges 5 and, when the shuttering is placed on the base, they abut their lower ends against the overlap, take the starting position, and the skeleton 1, under the action of its own weight moving along the guides of the brackets 4, becomes on the ledges 7, fix the shields 3 and the corner formwork elements 2 to the concrete pouring position. At the same time, the frame 1, together with the brackets 4, provides the necessary rigidity of the shields 3 and the corner formwork elements 2. After the design strength of the concrete is reached, the boards 3 and the corner formwork elements 2 are demolished. The frame 1 is pulled up by means of lifting means, the frame 1 is torn off from ledges 7 brackets 4, while in the hinged connection

5, the distance between the frame and the corner formwork elements 2 is reduced, which ensures the removal of the corner elements.

2 of concrete, then swivel

6 reduces the distance between the frame 1 and the shields 3, which ensures the removal of shields

3from concrete. With a further rise of the frame 1, the shields 3 and the corner shuttering elements

cops 2 under the action of their own weight, having approached the frame 1, hang on the hinges 5 and 6, creating a gap that provides free removal of the formwork.

The adaptation of the formwork to another building structure, construction is carried out by the parameters of the frame 1 and shields 3.

The proposed solution in comparison with the prototype has the following advantages:

reducing the labor intensity of the formwork work, reducing the weight of the block formwork and increasing its reliability in operation by simplifying the design;

Shortening the stripping time by reducing the stripping effort;

increased safety and ease of use.
