Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a reinforcement fixing card for a quick-detachable beam template. Background Art
[0002] During the main structure construction, the beam formwork reinforcement method generally adopts tension bolts and step-by-step tightening as reinforcement parts for fixing.
[0003] However, during the use of the tension bolts, the operators are required to drill holes on both sides of the formwork first. A lot of sawdust is generated during the drilling process. If the sawdust is not handled properly, it will easily affect the molding quality of the concrete. Secondly, the tensioning process is relatively complicated and the efficiency is low.
[0004] The reinforcement is carried out by step-by-step tightening, which can only serve as the lower reinforcement. It cannot ensure that the primary and secondary purlins on the beam side are stressed at the same time. The beam is prone to deformation. When pouring concrete, the step-by-step tightening is easy to fall off when vibrating the concrete in the beam, resulting in the beam bursting phenomenon. Utility Model Content

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.
[0028] Example 1:
[0029] like Figure 1 As shown, a reinforcement fixing card for a quick-detachable beam formwork includes a supporting square steel 1, a pair of clamping plates 2 and a latch plate 3.
[0030] like Figure 1 、 Figure 2 As shown, the supporting square steel 1 is horizontally arranged below the beam formwork, wherein one of the splints 2 is vertically fixed to the end of the supporting square steel 1 , and a sliding tube 4 is horizontally arranged at the lower end of the other splint 2 , and the sliding tube 4 is slidably connected to the outer wall of the supporting square steel 1 .
[0031] like Figure 2 、 Figure 3 As shown, a pair of clamps 2 are used to clamp the two sides of the beam template, and the upper end of each clamp 2 is bent to provide a folded edge 21 for hooking the upper end surface of the beam template.
[0032] like Figure 2 、 Figure 3 As shown, the latch piece 3 is wedge-shaped and passes through the sliding tube 4 horizontally, and a row of connecting holes 11 for the latch piece 3 to pass through are horizontally and spaced apart on the supporting square steel 1.
[0033] When the beam formwork needs to be fixed, a pair of splints 2 are controlled to face upward so that a pair of splints 2 are distributed on both sides of the beam formwork, and the supporting square steel 1 is made to contact the lower end surface of the beam formwork. Then, the supporting square steel 1 is controlled to slide horizontally so that the fixed splint 2 contacts one side of the beam formwork. Then, the movable splint 2 is controlled to drive the sliding tube 4 to slide horizontally so that the movable splint 2 clamps the other side of the beam formwork.
[0034] At the same time, the folded edges 21 on the pair of clamps 2 press against the upper end surface of the beam template, achieving the initial limit fixation of the entire fixing clamp. Finally, the latch piece 3 is removed, and the small end of the latch piece 3 is passed through the sliding tube 4 and the connection hole 11 on the supporting square steel 1. The sliding tube 4 is then pressed tightly, so that the pair of clamps 2 are tightly clamped on both sides of the beam template, achieving stable clamping and fixation of the beam template.
[0035] Therefore, by providing a nail-free fixing card, the beam formwork can be installed without drilling holes, ensuring the quality of concrete molding, facilitating installation, and improving construction efficiency. At the same time, the beam formwork can be stably clamped on both sides, ensuring that the primary and secondary keels on the beam side are stressed at the same time, avoiding the phenomenon of formwork bursting during vibration. At the same time, since the spacing between the pair of clamping plates 2 can be adjusted, it can adapt to beam formworks of different thicknesses, improving practicality.
[0036] like Figure 2 、 Figure 3 As shown, the clamping plate 2 is arranged in a right-angled trapezoidal shape, with a small end at the upper end and a large end at the lower end. The vertical surface of the clamping plate 2 faces inward and is used to contact the outer wall of the beam formwork. Therefore, when the force is applied at the lower end of the clamping plate 2, the clamping force will be transmitted to the upper end of the clamping plate 2, ensuring stable clamping of both sides of the beam formwork from top to bottom, avoiding stress concentration, and thus ensuring stability during the pouring of the beam formwork.
[0037] like Figure 2 、 Figure 3 As shown, the cross section of the splint 2 is I-shaped and includes a vertical plate 22, an inner plate 23 and an outer plate 24. The vertical plate 22 is a right-angled trapezoid, and the inner plate 23 and the outer plate 24 are respectively arranged on the vertical surface and the inclined surface on both sides of the vertical plate 22.
[0038] Therefore, by providing the splint 2 with an I-shaped cross section, the structural strength of the splint 2 itself can be improved, the splint 2 can be prevented from bending or damage, and the service life of the splint 2 can be increased.
[0039] like Figure 2 、 Figure 3 As shown, the lower end of the sliding tube 4 is rotatably connected to a hook 41, and a torsion spring is installed at the rotation position. The lower end of the supporting square steel 1 is provided with a row of slots 12 for the hooks 41 to engage. Therefore, when the sliding tube 4 slides, the hooks 41 will slide synchronously and engage with the corresponding slots 12, achieving double locking of the sliding tube 4 and enhancing the stability of the fixed clamp.
[0040] Example 2:
[0041] like Figure 4As shown, the splint 2 includes an upper plate 25, a lower plate 26 and an adjustment assembly 5. Guide rods 27 are vertically provided on both sides of the upper plate 25, and guide tubes 28 for vertical sliding of the guide rods 27 are provided on both sides of the lower plate 26 to increase the stability between the upper plate 25 and the lower plate 26.
[0042] like Figure 5 As shown, the adjustment assembly 5 is arranged between the upper plate 25 and the lower plate 26 and is used to control the upper plate 25 and the lower plate 26 to move closer to or farther away from each other. The adjustment assembly 5 includes a pair of adjustment blocks 51, a bidirectional screw 52 and four adjustment rods 53.
[0043] like Figure 5 As shown, a pair of adjustment blocks 51 are disposed between the upper plate 25 and the lower plate 26, and bidirectional screws 52 are threadedly connected to the pair of adjustment blocks 51. Adjustment rods 53 are arranged in pairs, with one end being rotatably connected to the upper and lower end surfaces of the adjustment blocks 51 and the other end being rotatably connected to the upper plate 25 and the lower plate 26.
[0044] When the height of the beam formwork changes, the bidirectional screw 52 can be controlled to drive a pair of adjustment blocks 51 to move closer or farther away from each other. At this time, the adjustment block 51 drives the adjustment rod 53 to flip synchronously, and controls the upper plate 25 and the lower plate 26 to move away or closer, thereby realizing the adjustment of the length of the entire splint 2 to adapt to beam formworks of different heights, improving the practicality of the entire fixing card, and at the same time realizing stable clamping of both sides of the beam formwork from top to bottom, avoiding stress concentration, thereby ensuring the stability of the beam formwork during casting.
[0045] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
