Description

Technical Field

[0001] The utility model relates to the technical field of building construction external angle template reinforcement, and more specifically to a external angle template reinforcement device. Background Art

[0002] The external angle refers to the intersection of the two sides of the outdoor wall of the building, that is, the convex angle is mostly 90°, such as the angle formed by the two walls at the corner of the walkway. In the reinforcement construction of the shear wall structure formwork, the formwork is usually reinforced by tightening the two sides with tension bolts through force calculation. However, since the external corners cannot be tightened with tension bolts, various reinforcement methods have emerged one after another, and the reinforcement effects are uneven. Various common concrete quality problems have become the worst-hit areas in the external corners. Under normal practices, workers use longitudinal and transverse steel pipe main keels to lock them with fasteners to keep the corners stressed and prevent the formwork from expanding, but the reinforcement effect is general, and common quality problems such as leakage and mold expansion often occur.

[0003] Therefore, how to provide a positive angle formwork reinforcement device to achieve simple and effective reinforcement of the positive angle formwork of the shear wall is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] In view of this, the utility model provides a positive angle template reinforcement device, aiming to solve the above technical problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positive angle template reinforcement device, comprising:

[0007] An L-shaped screw rod, wherein the L-shaped screw rod has a horizontal rod and a vertical rod, and the outer circumference of the horizontal rod is provided with a thread;

[0008] A sleeve, the sleeve is sleeved on the outer wall of the horizontal rod and is slidably connected thereto;

[0009] An angle steel, one of the panels of which is fixed to the outer wall of the sleeve, and the opening of the angle steel faces the vertical rod;

[0010] A nut is screwed onto an end of the horizontal rod facing away from the vertical rod.

[0011] The beneficial effect of the above technical solution is that the angle steel is welded and fixed with the sleeve, and the sleeve is sleeved on the horizontal rod of the L-shaped screw. When in use, at the template positions on both sides of the external angle part, one side is hooked on the inner wooden beam secondary keel through the bend formed at the connection between the horizontal rod and the vertical rod, and the other side is arranged on the outer wooden beam secondary keel through the plate surface opposite to the opening of the angle steel. Finally, the double nuts are screwed in and tightened to reinforce the external angle template.

[0012] Preferably, the length of the horizontal rod is not less than 200 mm, and the length of the vertical rod is 50 mm. The angle steel and the vertical rod are clamped on both sides of the template respectively, and the length of the horizontal rod is greater than the sum of the thickness of the template and the thickness of the wooden beams on both sides of the template.

[0013] Preferably, the L-shaped screw has a diameter of 14 to 20 mm and is made of Q235 steel, so as to ensure that the L-shaped screw has sufficient strength and does not deform after the nut is tightened, so as to facilitate turnover.

[0014] Preferably, the inner diameter of the sleeve is 16-22 mm and is larger than the outer diameter of the L-shaped screw, so as to ensure that the sleeve can slide freely along the outer wall of the horizontal rod.

[0015] Preferably, the angle steel is a ∠50×5mm angle steel.

[0016] Preferably, the sleeve has a length of 50 mm and a wall thickness of 3 mm.
