Abstract

The utility model relates to a binding and fixing structure for column longitudinal steel bars, which comprises a group of column steel bars, foundation steel bars and a fixer; the fixer is of a plate-shaped structure, and holes corresponding to the positions of the column steel bars are formed in the fixer; the fixer passes through the hole, with a set of post reinforcing bar nested fit, and make the fixer welded fastening in the bottom region of post reinforcing bar. The utility model adopts the fixer to be fixed at the bottom area of the column steel bar, thus solving the problem that the position deviation does not occur when the column longitudinal steel bar is bound; because the accuracy of location is improved, and then the hoist and mount efficiency of post reinforcement and two-sided coincide wallboard has been improved.

Description

Binding and fixing structure for longitudinal steel bars of column

Technical Field

The utility model relates to a vertical reinforcement of post ligature fixed knot constructs belongs to construction auxiliary assembly technical field.

Background

In the construction process of the double-sided superposed shear wall, whether the binding position of the longitudinal steel bars of the column is accurate or not determines the hoisting efficiency and accuracy of the wallboard. In the prior art, generally, longitudinal steel bars are installed by depending on field visual inspection of workers and experience, and then simple stirrup binding and temporary fixing are carried out. Can lead to the reinforcing bar displacement to take place the error when pouring the basic concrete, can lead to finally in wallboard hoist and mount in-process, need destroy the reinforcing bar and just can advance the wall installation, also can influence the mechanical properties of post simultaneously, reduce the antidetonation grade.

Disclosure of Invention

The utility model aims at providing a vertical reinforcement fixed knot of post constructs solves the vertical reinforcement of post and does not take place the problem of offset, can improve the hoist and mount efficiency of post reinforcement and two-sided coincide wallboard simultaneously.

The utility model adopts the following technical proposal:

a pillar longitudinal reinforcement binding and fixing structure comprises a group of pillar reinforcements, foundation reinforcements and a fixer 2; the fixer 2 is of a plate-shaped structure, and holes corresponding to the positions of the column steel bars are formed in the fixer; the fixer 2 is matched with the group of column reinforcing steel bars in a nesting mode through the holes, and the fixer 2 is fixed to the bottom area of the column reinforcing steel bars in a welding mode.

Preferably, after the foundation steel bar is poured, the upper part of the column steel bar is fixed by using the stirrups 1 and the tie bars 4.

Preferably, the holder 2 is formed in an L-shaped plate shape and is installed at a corner portion of a building.

Furthermore, a square hole for conveniently pouring concrete is formed in the fixer 2.

Furthermore, the stirrups 1 are rectangular, and each stirrup 1 hoops eight column steel bars.

Furthermore, the lacing wires 1 are in a straight shape, and each lacing wire fixes two adjacent column steel bars.

Furthermore, a set distance is arranged between the fixer 2 and the foundation 3, which is not less than 50mm, and the distance is staggered with the stirrup.

Further, the size of the outer contour of the fixer 2 is not larger than that of the outer contour of the post stirrup.

The beneficial effects of the utility model reside in that:

1) the fixing device is fixed at the bottom area of the column steel bar, so that the problem that the position of the column longitudinal steel bar is not deviated during binding can be solved;

2) because the accuracy of location is improved, and then the hoist and mount efficiency of post reinforcement and two-sided coincide wallboard has been improved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-2, a pillar longitudinal reinforcement binding and fixing structure includes a set of pillar reinforcements, foundation reinforcements, and a fixer 2; the fixer 2 is of a plate-shaped structure, and holes corresponding to the positions of the column steel bars are formed in the fixer; the fixer 2 is matched with the group of column reinforcing steel bars in a nesting mode through the holes, and the fixer 2 is fixed to the bottom area of the column reinforcing steel bars in a welding mode.

In this embodiment, referring to fig. 2, after the foundation steel bar is poured, the upper portion of the column steel bar is fixed by using the stirrup 1 and the tie bar 4.

In this embodiment, referring to fig. 1 and 2, the holder 2 is formed in an L-shaped plate shape and is installed at a pillar portion of a building.

In this embodiment, referring to fig. 1, the anchor 2 is provided with a square hole for facilitating the casting of concrete.

In this embodiment, referring to fig. 2, the stirrups 1 are rectangular, and each stirrup 1 hoops eight column reinforcements.

In this embodiment, referring to fig. 2, the tie bars 1 are in a straight shape, and each tie bar fixes two adjacent column steel bars.

In this embodiment, referring to fig. 2, a set distance is provided between the holder 2 and the base 3.

The fixer is manufactured on site by selecting a steel plate with the thickness of 5mm, the size is accurate, and the error is not more than +/-1 mm; the distance between the hollow holes of the reinforcing steel bars and the rectangle is not less than 5mm, the rectangle is maximized as far as possible, and concrete pouring and vibrating are facilitated. The holder can be made according to the actual form of the column, in addition to the above-described structure. The diameter of the longitudinal reinforcing steel bar hole on the fixer is 1mm larger than the designed size. The size of the outer contour of the fixer is not larger than that of the outer contour of the column stirrup.

During specific construction, after foundation steel bars are bound, firstly, the column steel bars are accurately installed according to the positions of drawings, then the fixator 2 is sleeved into the steel bars from the upper ends of the column steel bars, and the steel bars are welded and fixed after the position positioning is accurate; and after the foundation 3 is poured, binding and fixing the upper area of the column steel bar by adopting the stirrups 1 and the tie bars 4.

The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or improvements on the above embodiments without departing from the general concept of the present invention, and these changes or improvements should fall within the scope of the present invention.
