Description

I

The invention relates to the construction and can be used in the construction of monolithic reinforced concrete structures, mainly retaining walls, foundations.

There is a method of erecting vertical structures, in which opposing formwork boards are interconnected with squeezers remaining after dismantling in structure 1.

The disadvantage of this method is the sacrificial consumption of the material on the tie, especially when concreting massive structures.

There is also known a method of erecting vertical structures of monolithic reinforced concrete, including the installation of formwork seekers, connecting them together, reinforcing and concreting the structure and dismantling formwork {2.

The disadvantage of this method is the laboriousness of installing formwork boards in connection with the need to pre-assemble working platforms.

The purpose of the invention is to reduce labor costs in construction.

This goal is achieved by the fact that with the method of erecting a vertical structure of monolithic reinforced concrete, including the arrangement of formwork trays, connecting them to each other, reinforcement of the structure, beta-engraving and disassembling the formwork, at the same time From the standings of the formwork shields to each panel there is a vertical stand with holes, after connecting the shields to each other, threaded anchors are installed in the holes

to and remove them before dismantling the shield.

FIG. I depicts a fragment of a monolithic structure during its construction; in fig. 2 shows section A-A in FIG. one.

The method is carried out as follows.

IS

The first Id shields were installed and secured by any of the known methods. Simultaneously with the installation of shields, vertical racks 2 with holes ø are attached to each of them, which serve to clearly fix the latching shields in the design position.

Claims (2)

Formwork boards 1 are interconnected, for example, with wedge clamps. 3 Prior to the start of concreting of the first tusa, the extractable anchors 3 are inserted into the holes of the vertical posts, including conically parts 4 and turnkey heads 5. There is a thread on the conical parts. Then the concrete of the first Rus was laid. In this case, the anchors are provided in the body of the concrete. After the concrete has gained the required strength, the top of the first russia formwork shields are securely attached to the concrete using threaded anchors. 3. To further concrete the structure, install the second russia formwork shields, with the bottom of the second rus shields attached to the top of the first rus boards, for example , wedge joints. Then, to each shield of the second Rus, vertical stands are fastened and interconnected. After that, the threaded anchors are installed in the holes and the beta is placed on the second shaft. The installation of shields for subsequent Rus is performed in the same way. The lateral pressure of the concrete on the shields of the second tier is perceived by the vertical stands of the shields of the first trench formwork and through them and the wedge connections is transmitted to the shields of the first trench formwork. Shields of the first Rus formwork | H1 are fastened to the concrete with threaded anchors, in connection with which the second Russ shields are securely held in the design position and when concreting the second Rus the possibility of their displacement is excluded. After the concrete has set a second rusa of necessary strength, the threaded anchors 3 of the first rus are removed and the shields 1 are dismantled in order to rearrange them to the third Rus. Claims The method of erection of a vertical monolithic reinforced concrete construction, including installation of formworks, connecting them to each other, reinforcement of construction, concreting and dismantling of formwork, characterized in that, in order to reduce labor costs, simultaneously with the installation of formwork shields, vertical stands are attached to each shield with holes, and after connecting the shields to each other, threaded anchors are installed in the holes and removed before removing the shield.
