Description

Technical Field

[0001] This invention relates to the field of building construction, and more particularly to a horizontal support system for tying column steel reinforcement cages. Background Technology

[0002] Frame columns are the main vertical support structures in frame structures, bearing the loads from beams and slabs and transferring the loads to the foundation. Frame columns are primarily constructed using large steel molds. Before pouring, a reinforcing steel cage is inserted into the large steel mold to enhance the structural strength of the frame column. The reinforcing steel cage is pre-tied and then hoisted into the steel mold.

[0003] Currently, these steel column cages are mainly tied on the ground at the construction site in a "flat" manner. However, the cross-sectional and length dimensions of these steel column cages are relatively large, making it difficult to fix the positions of the main reinforcement bars and stirrups during the tying process, which affects the tying quality. Furthermore, the ground at the construction site is mainly uneven, making it impossible to tie the steel column cage at different positions along its length on the same horizontal plane, which also affects the tying quality. Therefore, steel column cages tied in this way often exhibit "torsion" phenomena, causing deformation stress. During hoisting, the position of the main reinforcement bars and the spacing of the stirrups may shift, which adversely affects the casting quality and structural strength of the frame column. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a horizontal support system for tying column reinforcement cages.

[0005] The technical solution of the present invention is: a horizontal support system for binding column steel cages, including support group A and support group B, support group A and support group B are arranged side by side and there is a certain distance between them. Support group A includes a number of support bodies A, and support group B includes a number of support bodies B. The number of support bodies A and the number of support bodies B are the same.

[0006] The main structures of bracket A and bracket B are the same, both including a support rod and several hooks. The lower end of the support rod is provided with a base. The support rod is a cylindrical rod. The outer side of the hook is provided with a sliding sleeve, which is fitted onto the support rod. A positioning mechanism is provided between the sliding sleeve and the support rod. The lower end of the hook in bracket A is provided with a level that can rotate freely. A laser emitter is installed on one side of the level. Both the level and the laser emitter are selected as small-sized models. The laser emitted by the laser emitter is parallel to the surface of the level.

[0007] Preferably, the lower end of the hook in the bracket A is provided with an assembly plate, which is fixedly connected to the hook by welding. A rotating support is installed on the assembly plate, and the rotating support and the assembly plate are fixedly connected by screws. The lower end of the rotating support is provided with a spherical groove, and a support rod is provided in the middle of the surface of the level. The upper end of the ball head rod is provided with a ball head that fits into the spherical groove to form a spherical pair, and a certain damping is provided between the ball head and the spherical groove.

[0008] Preferably, the positioning mechanism includes a threaded hole and a set screw on the side of the sliding sleeve, with the set screw inserted into the threaded hole and pressing against the side of the support rod.

[0009] Preferably, the support rods in bracket body A and bracket body B have protrusions on their sides along their generatrix direction, and the inner side of the sliding sleeve has a groove, with the protrusions fitting into the groove to form a sliding pair.

[0010] Preferably, the base is a cross-shaped base with a cylindrical seat at the center, and the lower end of the support rod is fitted into the cylindrical seat.

[0011] Preferably, a collar is installed on the level, and a sleeve is provided on one side of the collar, with the laser emitter installed inside the sleeve.

[0012] The beneficial technical effects of this invention are:

[0013] This horizontal support system uses support rods erected between two sets of supports to bind the column reinforcement cage. The support rods are placed between hooks on the two sets of supports, and the hooks can be freely adjusted in height on the support rods. In support group A, the lower end of the hook of support body A is equipped with a freely rotating level. After the level is adjusted to a horizontal state, the laser emitter emits a horizontal laser. This horizontal laser serves as a reference to quickly adjust the hooks in each support body A to the same horizontal height. Then, the direction of the level is adjusted, and the laser emitter emits a horizontal laser perpendicular to the original laser. The hooks in each support body B in support group B quickly adjust their height according to this horizontal laser, bringing all the hooks in support groups A and B to the same horizontal plane. This overcomes the problems caused by uneven ground, and the support cross braces can be placed on the same horizontal plane to provide support for the binding of the reinforcement cage. This solves the problems of difficult positioning of main bars and stirrups and the impact of uneven ground on binding quality in traditional binding methods, thus improving the casting quality and structural strength of the frame column.

[0021] Example 1, see appendix to the instruction manual. Figure 1 - 6, A horizontal support system for tying column steel reinforcement cages, comprising support group A and support group B, support group A and support group B are arranged side by side with a certain distance between them, support group A includes several support bodies A arranged side by side with the same distance, support group B includes several support bodies B arranged side by side with the same distance, support bodies A and support bodies B are slightly higher than the height of a human body, and the number of support bodies A and the number of support bodies B are the same;

[0022] The main structures of bracket A and bracket B are the same, both including a support rod and several hooks. The lower end of the support rod is provided with a base, and the outside of the hook is provided with a sliding sleeve, which is fitted onto the support rod. A positioning mechanism is provided between the sliding sleeve and the support rod, so the height of the hook can be adjusted on the support rod. The lower end of the hook in bracket A is provided with a freely rotatable level. A laser emitter is installed on one side of the level. The laser emitted by the laser emitter is parallel to the surface of the level. The level is used to provide a reference for the laser emitter so that it can emit a horizontal laser.

[0023] The lower end of the hook in the bracket A is provided with an assembly plate, on which a rotating support is installed. The lower end of the rotating support is provided with a spherical groove. A support rod is provided in the middle of the surface of the level. The upper end of the ball head rod is provided with a ball head that fits into the spherical groove to form a spherical pair. Under the action of the spherical pair, the level can rotate freely to adjust the direction and angle. There is damping between the ball head and the spherical groove, and it can be self-positioned after adjustment.

[0024] The positioning mechanism includes a threaded hole and a set screw on the side of the sliding sleeve. The set screw is inserted into the threaded hole and presses against the side of the support rod. After the hook adjusts its height through the sliding sleeve, the set screw locks the two together.

[0025] The support rods in bracket body A and bracket body B have protrusions on their sides along their generatrix, and the inner side of the sliding sleeve has a groove. The protrusions are matched and inserted into the groove. The protrusions and grooves provide guidance for the sliding adjustment of the hook height, prevent the sliding sleeve from rotating in the circumferential direction, facilitate the adjustment of the hook position on the support rod, and at the same time enable the upper and lower hooks to be on the same straight line, which facilitates the positioning between the upper and lower hooks.

[0026] The base is designed as a cross-shaped base with a cylindrical seat at the center. The lower end of the support rod is fitted into the cylindrical seat, which allows for easy disassembly and docking of the support rod and the base, facilitating transfer and transportation.

[0027] The level is equipped with a collar, and a sleeve is provided on one side of the collar, with the laser emitter installed inside the sleeve.

[0028] The process of using this invention is as follows:

[0029] ① Place a support frame (A) on the ground at the construction site, according to the reinforcement of the concrete columns.

[0030] Adjust the cage's dimensions, adjust the height of each hook on the support rod within the bracket body, and lock each hook onto the support rod using set screws. Then, freely rotate the level to adjust it to a horizontal state.

[0031] ② The laser emitter on one side of the level emits a horizontal laser, while the rest of the support body A...

[0032] Using the horizontal laser as a reference, the height of the hooks is adjusted so that the hooks in each bracket body are adjusted to the same horizontal height, forming a bracket assembly.

[0033] ③ Adjust the level rulers in each support body to be horizontal, so that these level rulers are level.

[0034] The laser emitter emits a horizontal laser that is perpendicular to the horizontal laser in step ② or perpendicular to the arrangement direction of bracket group A. Then, according to the horizontal laser, the corresponding bracket body B is placed in sequence, and the hooks in bracket body B are adjusted to be at the same horizontal height as the hooks in bracket body A, thus forming bracket group B.

[0035] ④ Place horizontal bracing rods between the corresponding hooks of support group A and support group B, for each layer of horizontal bracing rods.

[0036] The struts are at the same horizontal height. Then, the main reinforcement bars are arranged on top of the horizontal struts. Finally, the reinforcement cage is tied according to the design requirements of the column reinforcement cage.
