Description

Technical Field

[0001] The utility model relates to the technical field of building formwork supports, in particular to a fixed support for building engineering formwork. Background Technique

[0002] The new steel back rib support system is a new formwork reinforcement system, which is an upgraded product of the traditional round pipe + wooden square system. It is also called a complete set of formwork support system. Different from the traditional reinforcement system, it is forged from high-quality steel and replaces the wooden square and steel pipe in the traditional formwork process.

[0003] The new steel back rib support system can be applied to various shear wall structures, frame-shear wall structures, frame structures, wall-connected columns, large underground parking lots, etc. It is mainly tightened through wall bolts or through pull tabs and back rib supports (pull tabs are used to tighten the formwork, and supports are used to clamp and fix the back ribs) to prevent the formwork from expanding under stress during concrete pouring.

[0004] When the steel back rib support structure is in use, multiple parallelly distributed wooden strips or square steel pipes are fixed on the surface of the formwork to reinforce the vertical direction of the formwork. The fixed back rib support is in contact and extrusion with the wooden strips or square steel pipes to achieve the fastening of the formwork. The force-bearing contact surface of the formwork is small, and the part of the formwork between two adjacent wooden strips (or square steel pipes) is prone to deformation. Based on this, a fixed support for building engineering formwork is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixed support for building engineering formwork to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixed support for building engineering formwork, including a wall bolt for penetrating two formworks. The outer side of the wall bolt is sleeved with a main steel back rib for fastening the two wall bolts. The main steel back rib includes a back rib main body, a fixing piece, an L-shaped pressing edge, and a docking slot.

[0007] The two back rib main bodies are symmetrically distributed up and down. The fixing piece is fixed in the middle of the two back rib main bodies. The L-shaped pressing edges are symmetrically fixed on both sides of the back rib main body. The docking slot is opened on the back rib main body and penetrates the bottom of the back rib main body.

[0008] A plurality of the fixing pieces and L-shaped pressing edges are arranged horizontally, and the fixing pieces and L-shaped pressing edges are staggered with each other.

[0009] The two back rib main bodies are sleeved on the outer side of the wall bolt. The fixing piece is in contact with the reinforcement keel on the surface of the formwork, and the L-shaped pressing edge is in contact with the surface of the formwork to realize the extrusion and fastening of the formwork.

[0010] As a further solution of the utility model: the horizontal length of the L-shaped edge pressing is matched with the distribution spacing of two adjacent reinforcing keels, and the horizontal width of the fixing piece is matched with the horizontal width of the reinforcing keel.

[0011] As a further solution of the utility model: a plurality of uniformly distributed insertion slots are formed at the top of the wall-piercing bolt, and the insertion slots penetrate through the bottom of the wall-piercing bolt. The inclined iron pin is inserted into the insertion slot and abuts against the side surface of the L-shaped edge pressing to limit and fix the main backrest body.

[0012] As a further solution of the utility model: the main backrest body, the fixing piece, the L-shaped edge pressing, and the docking slot are integrally formed by punching and stamping processes, and the two main backrest bodies are fixedly welded through the fixing piece.

[0013] As a further solution of the utility model: a wall-piercing pipe is sleeved outside the part of the wall-piercing bolt located between the two templates to facilitate the later disassembly of the wall-piercing bolt.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By providing a main steel backrest with a fixing piece and an L-shaped edge pressing, the fixing piece abuts against the side surface of the reinforcing keel, and the L-shaped edge pressing abuts against the surface of the template. Compared with the structure of the traditional main steel backrest that only abuts against the surface of the reinforcing keel, the contact area for pressing the surface of the template is larger, so that the part of the template distributed between the two reinforcing keels is also tightened, further reducing the possibility of the template deforming and improving the fastening effect of the template.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a fixing bracket for a building engineering formwork includes a wall-piercing bolt 1 for penetrating two formworks 5. A main steel backstrap 3 for fastening the two wall-piercing bolts 1 is sleeved outside the wall-piercing bolt 1. The main steel backstrap 3 includes a backstrap main body 301, a fixing piece 302, an L-shaped edge pressing 303, and a butt joint slot 304;

[0022] The two backstrap main bodies 301 are symmetrically distributed up and down. The fixing piece 302 is fixed in the middle of the two backstrap main bodies 301. The L-shaped edge pressing 303 is symmetrically fixed on both sides of the backstrap main body 301. The butt joint slot 304 is opened on the backstrap main body 301 and penetrates the bottom of the backstrap main body 301;

[0023] A plurality of fixing pieces 302 and L-shaped edge pressings 303 are arranged in the horizontal direction, and the fixing pieces 302 and L-shaped edge pressings 303 are arranged in a staggered manner;

[0024] The two backstrap main bodies 301 are sleeved outside the wall-piercing bolt 1. The fixing piece 302 is attached to the reinforcement keel 6 on the surface of the formwork 5, and the L-shaped edge pressing 303 is attached to the surface of the formwork 5 to realize the extrusion and fastening of the formwork 5;

[0025] A plurality of uniformly distributed insertion slots 2 are opened at the top of the wall-piercing bolt 1. The insertion slots 2 penetrate the bottom of the wall-piercing bolt 1. The inclined iron pin 4 is inserted into the insertion slots 2 and attached to the side surface of the L-shaped edge pressing 303 to realize the limit fixation of the backstrap main body 301;

[0026] A wall-piercing pipe 7 is sleeved outside the part of the wall-piercing bolt 1 between the two formworks 5 to facilitate the later disassembly of the wall-piercing bolt 1.

[0027] In this embodiment, it should be supplemented and explained that: the length of the wall-piercing pipe 7 is consistent with the thickness of the wall structure. The formwork 5 is preset with a notch for the wall-piercing bolt 1 to penetrate, and the notches are distributed between the two reinforcement keels 6;

[0028] During assembly, the wall-piercing pipe 7 is placed between two formworks 5 and aligned with the notch. Then, the wall-piercing bolts 1 are sequentially passed through one formwork 5, the wall-piercing pipe 7, and the other formwork 5. Then, the main steel backing rib 3 is sleeved on the wall-piercing bolts 1. After that, the inclined iron pin 4 is inserted into the insertion slot 2 and pressed against the main steel backing rib 3 to achieve the side fastening operation of the main steel backing rib 3 on the formwork 5 (it should be noted that: the steel backing rib support system also includes structures such as extended connectors and corner connectors. Since only the structure of the main steel backing rib 3 is improved in this solution, the existing structures such as extended connectors and corner connectors are not elaborated here);

[0029] During the above operation process, the fixing piece 302 on the main steel backing rib 3 is attached to the side of the reinforcement keel 6, and the L-shaped pressing edge 303 is attached to the surface of the formwork 5. Compared with the traditional structure where the main steel backing rib only contacts the surface of the reinforcement keel, the contact area for pressing the surface of the formwork 5 is larger, so that the part of the formwork 5 distributed between the two reinforcement keels 6 is also tightened, further reducing the possibility of deformation of the formwork 5 and improving the fastening effect of the formwork 5.

[0030] Please refer specifically to Figures 1 to 3 , the horizontal length of the L-shaped pressing edge 303 matches the distribution distance between two adjacent reinforcement keels 6, and the horizontal width of the fixing piece 302 matches the horizontal width of the reinforcement keel 6.

[0031] In this embodiment: with this structure, the fastening area of the formwork 5 is increased through the L-shaped pressing edge 303. At the same time, the L-shaped pressing edge 303 can also limit the end face of the reinforcement keel 6, reducing the possibility of deformation of the reinforcement keel 6.

[0032] Please refer specifically to Figures 1 to 3 , the backing rib main body 301, the fixing piece 302, the L-shaped pressing edge 303, and the docking slot 304 are integrally formed by punching and stamping processes, and the two backing rib main bodies 301 are welded and fixed through the fixing piece 302.

[0033] In this embodiment: with this structure, the convenient processing and production of the main steel backing rib 3 can be realized. Its overall processing technology is simple and is convenient for popularization and production.

[0034] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
