Description

Technical Field

[0001] This utility model belongs to the field of auxiliary clamping technology for concrete structures, and particularly relates to a beam clamp for side reinforcement of concrete structure beams. Background Technology

[0002] In the manufacturing process of concrete structural beams, templates are usually used for production. The templates need to be positioned and assembled first to form cavities that can form concrete structural beams. In order to improve the structural strength of the templates, clamps are usually used to fix and hold the templates on the outside to reduce the problem of template deformation caused by pressure during the pouring process, which would affect the forming effect of the concrete structural beam.

[0003] In the existing technology, most beam clamps that reinforce the sides of concrete structural beams use a clamping method for fixation. The locking structure generally lacks mutual guidance and nesting, resulting in insufficient stability and failing to provide a stable clamping effect. Utility Model Content

[0004] This utility model provides a beam clamp for side reinforcement of concrete structural beams. The utility model is implemented as follows: A beam clamp for side reinforcement of concrete structural beams includes:

[0005] A first rod and a second rod, wherein the first rod extends into a sliding cavity provided inside the second rod, and the second rod is further provided with a driving rod for driving the first rod to move.

[0006] The driving rod includes a driving rod and a limiting mechanism for restricting the rotation of the driving rod. The driving rod extends into a guide cavity provided inside the first rod. A driving plate that is threadedly engaged with the driving rod is provided in the guide cavity. When the driving rod rotates, the driving plate drives the first rod to move back and forth.

[0007] Preferably, the first rod has a first clamping plate at its end away from the second rod, and the second rod has a second clamping plate at its end away from the first rod.

[0008] Preferably, the second rod has a limiting plate inside, which divides the interior of the second rod into a sliding cavity and a locking cavity, and the driving rod passes through the sliding cavity and the locking cavity.

[0009] Preferably, the limiting plate is provided with a first bearing for fixing the drive rod, and the drive rod passes through the second rod and extends out of the second rod at the end away from the locking cavity.

[0010] Preferably, the drive plate is provided with a threaded hole, and the portion of the drive rod extending into the guide cavity is threadedly engaged with the drive plate.

[0011] Preferably, the limiting mechanism includes a limiting arc plate located in the locking cavity and a locking bolt penetrating the side wall of the second rod, wherein the limiting arc plate abuts against the driving rod during the screwing of the locking bolt.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0013] The beam clamp for side reinforcement of concrete structural beams provided by this utility model has a first rod extending into a sliding cavity provided in a second rod. The drive rod extends into the guide cavity and is divided into a screw structure that is threadedly engaged with the drive plate. When the drive rod rotates, the drive plate drives the first rod to move back and forth.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a beam clamp for reinforcing the side of a concrete structural beam, such as... Figures 1-5 As shown, the beam clamp for reinforcing the side of a concrete structural beam includes:

[0024] A first rod 110 and a second rod 210 are provided. The first rod 110 extends into a sliding cavity 201 provided inside the second rod 210. A first clamping plate 120 is provided at the end of the first rod 110 away from the second rod 210, and a second clamping plate 220 is provided at the end of the second rod 210 away from the first rod 110. A driving rod 300 is also provided inside the second rod 210 to drive the first rod 110 to move. As the driving rod 300 rotates, the first clamping plate 120 and the second clamping plate 220 can move towards each other or away from each other to achieve the purpose of clamping the side of the concrete structure beam.

[0025] The driving rod 300 includes a driving rod 310 and a limiting mechanism. The driving rod 310 extends into a guide cavity 101 inside the first rod 110. The guide cavity 101 contains a driving plate 130 that is threadedly engaged with the driving rod 310. The driving plate 130 has a threaded hole. The driving rod 310 extends into the guide cavity 101 and is divided into a screw structure that is threadedly engaged with the driving plate 130. When the driving rod 310 rotates, the driving plate 130 drives the first rod 110 to reciprocate. The driving rod 310, the first rod 110, and the second rod 210 form a cross-nested locking mechanism, which interacts with each other to improve the structural strength and meet the strength requirements of the clamping and fixing mechanism.

[0026] The other end of the drive rod 310 passes through the second rod 210 and extends out of the second rod 210. Here, the second rod 210 has a cavity inside. The cavity is divided into two parts by the limiting plate 230 inside the cavity, namely a sliding cavity 201 and a locking cavity 202. The limiting mechanism extends to the locking cavity 202 to lock the drive rod 310 located in the locking cavity 202.

[0027] In a further preferred embodiment of this utility model, the guide cavity 101 adopts a circular structure, the sliding cavity 201 and the locking cavity 202 are both square structures, the cross section of the first rod 110 is adapted to the cross section of the sliding cavity 201, and the guide cavity 101 is a circular structure and is adapted to the drive rod 310.

[0028] As a preferred embodiment of this embodiment, the limiting mechanism includes a limiting arc plate 320 located in the locking cavity 202 and a locking bolt 330 penetrating the side wall of the second rod 210. During the screwing of the locking bolt 330, the limiting arc plate 320 abuts against the driving rod 300.

[0029] Specifically, the limiting arc plate 320 has a flat end face and an arc-shaped groove. The locking bolt 330 extends spirally from the outside into the locking cavity 202 through a screw hole on the side wall of the second rod 210 that connects to the locking cavity 202. The end of the locking bolt 330 screwed into the locking cavity 202 abuts against the flat end face of the limiting arc plate 320 and presses the arc-shaped groove of the limiting arc plate 320 against the side wall of the drive rod 310. Here, the inner edge of the arc-shaped groove is made of damping material, which has a strong limiting effect and prevents the drive rod 310 from reversing. The limiting arc plate 320 is designed to move vertically along the locking cavity 202 and cannot deflect around the drive rod 310.

[0030] In a preferred embodiment of this invention, the limiting plate 230 is provided with a shaft hole at its center, and the second rod 210 is provided with a countersunk hole structure to accommodate the drive rod 310 passing through. The bearing provided on the drive rod 310 helps the drive rod 310 to achieve a rotatable connection with the countersunk hole and the shaft hole.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
