Description

Technical Field

[0001] This utility model relates to the technical field of reinforced concrete components, specifically to a construction structure for positioning and installing reinforcing steel formwork in reinforced concrete components. Background Technology

[0002] Reinforcing steel formwork refers to the formwork used for freshly poured concrete and the entire structural system supporting it. The part that contacts the concrete and controls its predetermined dimensions, shape, and position is called the formwork. The supporting system consists of rods, trusses, connectors, metal fittings, and temporary working bridges that support and fix the formwork. Therefore, a positioning construction structure is needed to fix the reinforcing steel formwork. For example, in the reinforcing steel formwork positioning construction structure of reinforced concrete components disclosed in CN207420036U, tie bolts are used to pass through the formwork on both sides and tighten the main ribs on the outer sides of the formwork using connecting U-shaped clamps. The pouring cavity is equipped with transverse and longitudinal reinforcing bars arranged horizontally and vertically. The positioning construction structure is characterized by a sleeve assembly for fitting the tie bolts. The sleeve assembly includes a sleeve, a top support, and a clamp. The outer wall of the sleeve has external threads, and both ends of the sleeve are threadedly fixed to the top support for abutting against the formwork on both sides. The top support is bowl-shaped. At least one clamp is threadedly connected to the outer wall of the sleeve for clamping the transverse reinforcing bars in the reinforced concrete component.

[0003] However, when using pliers to fix the rebar formwork, the external thread on the sleeve is used to move left and right to control the pliers to clamp and fix the rebar. However, the movement of the thread on the sleeve will cause rotation, which will affect the positioning and clamping of the rebar by the pliers. Utility Model Content

[0004] To address this issue, this utility model provides a construction structure for positioning rebar formwork in reinforced concrete components. This structure solves the problem in the prior art where the external thread on the sleeve moves left and right to control the clamping and fixing of the rebar by the pliers. However, the movement of the thread on the sleeve causes rotation, which affects the positioning and clamping of the rebar by the pliers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A construction structure for positioning rebar formwork in reinforced concrete members includes a clamp body. The clamp body is equipped with a fixing device for positioning and clamping the rebar formwork in cooperation with the clamp body. The clamp body is also equipped with an adjustment device for driving the fixing device to move left and right.

[0007] The adjustment device includes an adjustment component disposed within the caliper body for driving the fixing device to move left and right, and a drive component for driving the adjustment component to rotate is disposed at the right end of the adjustment component.

[0008] The fixing device includes a movable component that is threadedly connected to the adjusting component for left and right movement, and a claw component that is movably connected within the movable component for positioning and clamping the rebar template in cooperation with the clamp body.

[0009] Furthermore, the caliper body has a placement slot for placing the adjustment component, and the front end of the caliper body has a locking hole for locking the claw component. There are several locking holes, and the several locking holes are distributed in a linear array on the front side of the caliper body.

[0010] Furthermore, the right end of the caliper body is provided with a second locking hole for locking the drive assembly, and there are several second locking holes. A wear-resistant layer is fixedly installed on the caliper body for cooperating with the claw assembly to position and clamp the rebar template.

[0011] Furthermore, the adjustment component includes a threaded rod disposed in the placement slot for driving the moving component to move left and right, and a guide rod disposed below the threaded rod for assisting the moving component to move left and right.

[0012] Furthermore, the drive assembly includes a handwheel fixedly mounted on the right end of the threaded rod for driving the threaded rod to rotate, and a bolt is provided on the wheel body of the handwheel for engaging with the locking hole to lock the handwheel.

[0013] Furthermore, the moving assembly includes a threaded sleeve plate that is threadedly connected to the threaded rod, and the plate body of the threaded sleeve plate is provided with a bolt for locking the claw assembly.

[0014] Furthermore, the jaw assembly includes a jaw that is movably connected to a threaded sleeve plate, and the bottom end of the jaw has a locking hole three for engaging with locking hole one to fix locking hole three inside the caliper body.

[0015] This utility model has the following advantages:

[0016] By configuring the clamp body, adjustment device, and fixing device, when it is necessary to position and clamp the steel reinforcement formwork in reinforced concrete components, the fixing bolts can be removed from locking holes one and three. Then, the jaws can be rotated downwards around the bottom of the threaded sleeve plate. Bolt two can then be inserted through the jaws and the threaded sleeve plate to lock the jaws. Bolt one can be loosened and removed from the handwheel to release the locking of the handwheel. Then, the threaded rod can be rotated by the handwheel, causing the threaded sleeve plate to move along the threaded rod towards the wear-resistant layer on the clamp body. By utilizing the cooperation between the jaws and the wear-resistant layer on the clamp body, the steel reinforcement formwork in reinforced concrete components can be quickly positioned, clamped, and fixed.

[0028] Please see Figures 1-4 This utility model provides a construction structure for positioning formwork for reinforcing bars in reinforced concrete components.

[0029] The device includes a clamp body 100, a fixing device 300 for positioning and clamping the rebar formwork in cooperation with the clamp body 100, and an adjusting device 200 for driving the fixing device 300 to move left and right.

[0030] The caliper body 100 has an L-shaped appearance to facilitate clamping the caliper body 100 onto the rebar template. The adjusting device 200 controls the fixing device 300 to cooperate with the caliper body 100, thereby achieving positioning, clamping and fixing of the rebar template. The caliper body 100 has a placement slot 101 for placing the adjusting component 220. The front end of the caliper body 100 has a locking hole 102 for locking the claw component 320. There are several locking holes 102, and the several locking holes 102 are distributed in a linear array on the front side of the caliper body 100.

[0031] The caliper body 100 has a locking hole 103 on its right end for locking the drive assembly 210. There are several locking holes 103, which are arranged in a circumferential array on the right end of the caliper body 100. A wear-resistant layer 104 is fixedly installed on the caliper body 100 for positioning and clamping the rebar template in cooperation with the claw assembly 320. Therefore, the wear-resistant layer can extend the service life of the caliper body 100.

[0032] The adjustment device 200 includes an adjustment component 220 disposed within the caliper body 100 for driving the fixing device 300 to move left and right, and a drive component 210 disposed at the right end of the adjustment component 220 for driving the adjustment component 220 to rotate.

[0033] The adjustment assembly 220 includes a threaded rod 221 disposed in the placement slot 101 for driving the moving assembly 310 to move left and right, and the rod body of the threaded rod 221 is connected to the caliper body 100 through a bearing to facilitate the rotation of the threaded rod 221; a guide rod 222 is disposed below the threaded rod 221 for assisting the moving assembly 310 to move left and right.

[0034] The drive assembly 210 includes a handwheel 211 fixedly installed on the right end of the threaded rod 221 for driving the threaded rod 221 to rotate. The handwheel 211 has a bolt 212 for locking the handwheel 211 by engaging with the locking hole 103. This allows the handwheel 211 to be locked by threading the bolt 212 through the locking hole 103 on the caliper body 100, preventing the handwheel 211 from rotating again. When it is necessary to position and clamp the steel reinforcement formwork in the reinforced concrete component, the bolt 212 can be loosened and removed from the handwheel 211 to release the locking of the handwheel 211. Then, by rotating the threaded rod 221 through the handwheel 211, the fixing device 300 can be controlled to approach the wear-resistant layer 104 on the caliper body 100, thereby achieving the positioning, clamping and fixing of the steel reinforcement formwork in the reinforced concrete component.

[0035] The fixing device 300 includes a moving component 310 that is threadedly connected to the adjusting component 220 for left and right movement, and a claw component 320 that is movably connected within the moving component 310 for positioning and clamping the rebar template in cooperation with the clamp body 100.

[0036] The moving assembly 310 includes a threaded sleeve 311 that is threadedly connected to the threaded rod 221, and a guide rod 222 passes through the plate body of the threaded sleeve 311; the plate body of the threaded sleeve 311 is provided with a bolt 312 for locking the claw assembly 320.

[0037] The chuck assembly 320 includes a chuck 321 movably connected to the threaded sleeve 311, and the chuck 321 is connected to the bottom of the threaded sleeve 311 via a hinge rod to facilitate the chuck 321 moving around the threaded sleeve 311 and retracting into the caliper body 100. The bottom end of the chuck 321 has a locking hole 322 for engaging with locking hole 102 to fix locking hole 322 within the caliper body 100. The diameter of locking hole 322 is the same as that of locking hole 102, allowing a fixing bolt to pass through both locking hole 102 and locking hole 322, thus enabling the chuck 321 to be retracted onto the caliper body 100 for easy carrying. This facilitates the handling of steel reinforcement formwork in reinforced concrete components. When the plate is positioned and clamped, the fixing bolts can be removed from the locking hole 102 and the locking hole 322. Then, the pawl 321 is rotated downward around the bottom of the threaded sleeve plate 311. Then, the bolt 212 is inserted through the pawl 321 and the threaded sleeve plate 311 to lock the pawl 321. The bolt 212 is loosened and removed from the handwheel 211 to release the locking of the handwheel 211. Then, the threaded rod 221 is rotated by the handwheel 211, so that the threaded sleeve plate 311 moves along the threaded rod 221 toward the wear-resistant layer 104 on the clamp body 100. By utilizing the cooperation between the pawl 321 and the wear-resistant layer 104 on the clamp body 100, the positioning and clamping of the steel reinforcement formwork in the reinforced concrete component can be quickly achieved.

[0038] Although the present invention has been described in detail above with general and specific descriptions, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
