Description

Technical Field

[0001] The utility model relates to an independent foundation column steel bar force supporting structure, belonging to the technical field of building construction. Background Art

[0002] Before pouring concrete on the cushion layer to form the independent foundation column steel bar force support structure, the steel bars need to be bundled and formed in the internal space of the formwork. In order to prevent the steel bars of the independent foundation column steel bar force support structure from shifting during the pouring of concrete, displacement restriction is required.

[0003] The existing method for limiting the displacement of steel bars is shown in Chinese Patent Publication No. CN213062926U. The inclined supports are installed with the external slope as the support point to limit the position of the steel bars. Although this method can limit the displacement of the steel bars, when there is no external slope environment on a flat foundation, the problem of not being able to limit the displacement of the steel bars in the template occurs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an independent foundation column steel bar force supporting structure.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides an independent foundation column steel bar force support structure, comprising:

[0007] Cushion;

[0008] There is a stepped formwork on the cushion layer, and there is a hollow space inside the stepped formwork for containing concrete. Steel bars are installed in the hollow space, and the steel bars extend from the top of the stepped formwork;

[0009] Reinforced iron parts are installed on the top of the stepped formwork, and the reinforced iron parts have pads that contact the steel bars to limit displacement.

[0010] A first-order formwork is installed on the cushion layer, and a second-order formwork is installed on the first-order formwork. The second-order formwork and the first-order formwork form a stepped formwork.

[0011] The second-order formwork and the first-order formwork have hollow spaces inside for accommodating concrete.

[0012] The reinforcing iron piece is installed on the top of the second-order formwork, and external pins are inserted and installed at both ends of the reinforcing iron piece, and the two external pins are pressed against the outer side of the second-order formwork.

[0013] An inner pin is inserted and installed in the middle of the reinforcing iron piece, a reinforcing iron body is inserted on the inner pin, and a pad is fixed on the inner side of the reinforcing iron body to contact the steel bar for displacement limitation.

[0014] The cushion block is an elastic body made of elastic rubber.

[0015] The beneficial effects of the utility model are as follows: reinforcing iron pieces are installed on the step-type formwork, and pads on the reinforcing iron pieces contact the steel bars to limit their displacement, so that the steel bars are force-limited by the reinforced iron body at the top of the step-type formwork without the need for an external slope as a support point, thus solving the problem of being unable to limit the displacement of the steel bars in the formwork when there is no external slope environment on a flat foundation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a main schematic diagram of the utility model;

[0017] In the figure: 1- cushion layer; 11- first-order formwork; 12- second-order formwork; 2- reinforcement bars; 3- reinforcement iron parts; 31- external pins; 32- internal pins; 4- reinforcement iron body; 5- cushion blocks. DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] like Figure 1 shown.

[0020] An independent foundation column steel bar force support structure of the present application comprises:

[0021] The cushion layer 1 is at the bottom, a first-order formwork 11 is installed on the cushion layer 1, and a second-order formwork 12 is installed on the first-order formwork 11. The second-order formwork 12 and the first-order formwork 11 form a stepped formwork; the second-order formwork 12 and the first-order formwork 11 have hollow spaces inside for accommodating concrete poured later.

[0022] Steel bars 2 are installed in the hollow space inside the second-order formwork 12 and the first-order formwork 11 , and the steel bars 2 extend from the top of the second-order formwork 12 .

[0023] A reinforcing iron piece 3 is installed on the top of the second-order formwork 12 , and external plugs 31 are inserted and installed at both ends of the reinforcing iron piece 3 , and the two external plugs 31 are pressed against the outer side of the second-order formwork 12 .

[0024] An inner pin 32 is inserted and installed in the middle of the reinforcing iron piece 3, and a reinforcing iron body 4 is inserted on the inner pin 32. A pad 5 is fixed on the inner side of the reinforcing iron body 4 to contact the steel bar 2 for displacement limitation. The pad 5 is an elastic body made of elastic rubber.

[0025] A reinforcing iron piece 3 is installed on the stepped formwork formed by the second-order formwork 12 and the first-order formwork 11, and a reinforcing iron body 4 is installed on the reinforcing iron piece 3 through an inner pin 32. A pad 5 on the inner side of the reinforcing iron body 4 contacts the steel bar 2 for displacement limitation, so that the steel bar 2 is force limited by the reinforcing iron body 4 at the top of the stepped formwork without the need for an external slope as a support point, thereby solving the problem of being unable to limit the displacement of the steel bar in the formwork when there is no external slope environment on a flat foundation.

[0026] The elastic pad 5 is a flexible body. When the concrete is poured into the hollow space inside the second-order formwork 12 and the first-order formwork 11 and vibrated, the pad 5 isolates the vibration transmission between the steel bar 2 and the second-order formwork 12 and the first-order formwork 11, avoiding resonance that affects the overall position and stability of the connection.
