Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and more specifically, to a reusable composite board strip hanging formwork bracket. Background Art

[0002] In the current construction field, composite slabs are a widely used technology. Composite slabs are often used in combination with plate-strip formwork. Since there will be gaps between the composite slabs and the plate-strip formwork, leakage will occur, resulting in waste of labor and materials, so the composite slabs and the plate-strip formwork need to be tightened.

[0003] A Chinese patent with publication number CN207211753U discloses a floor formwork hanging device, including a top bracket, a formwork support frame and a connecting assembly for fastening the top bracket and the formwork support frame. The lower surface of the top bracket is used to abut against the upper surface of the floor slab. The formwork support frame includes a base and a plurality of formwork support rods horizontally distributed around the base. The formwork support rods are rotatably connected to the base, and a supporting platform for horizontally supporting the formwork support rods is provided on the base. The connecting assembly is detachably connected to the top bracket, and the bottom end of the connecting assembly is fixedly connected to the base.

[0004] Although this technology fastens the composite plate and the plate strip formwork through the connecting components, in the actual construction site, due to the complexity of the construction environment, the surface of the connecting component exposed outside the protective cover is often damaged by the influence of construction personnel and construction machinery. At the same time, the top side of the connecting component is exposed to the outside and is more easily affected by construction personnel and machinery. This will further reduce the service life of the connecting component that could have been recycled and reused.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0034] Example

[0035] A reusable composite plate strip hanging formwork support, such as Figures 1 to 3As shown, it includes a fastening component 1 and a protection component 2. In this embodiment, the protection component 2 includes a protection tube 21 that passes through the composite plate and the plate strip to be fastened area. The fastening component 1 includes a rod 11 that is detachably connected to the inside of the protection tube 21. Pressure pieces 12 and 13 are provided at both ends of the rod 11. The pressure pieces 12 and 13 apply opposite forces to the composite plate and the plate strip to be fastened area. Protective pieces 1 22 and 23 are provided at both ends of the rod 11. The protection tube 21, the protection piece 1 22, and the protection piece 2 23 at least partially shield the outer surface of the rod 11. The protection piece 1 22 contacts the edge of the composite plate and the plate strip to be fastened area. The protection piece 2 23 contacts the edge of the composite plate and the plate strip to be fastened area. The protection piece 1 22 and the protection piece 2 23 are detachably connected to the rod 11. While the fastening component 1 reduces the occurrence of slurry leakage, the protection component 2 strengthens the protection of the rod 11, especially the two ends of the rod 11, and reduces the wear of the rod 11 in a complex construction environment.

[0036] Preferably, an implementation scheme is provided, namely, the required relative pressure is formed by threaded cooperation and abutment, the two ends of the rod 11 are arranged as threaded sections, the pressure piece 12 is provided with a threaded hole 1, and the pressure piece 2 13 is provided with a threaded hole 2, the threaded hole 1 and the threaded hole 2 cooperate with the thread of the rod 11, and the pressure piece 12 and the pressure piece 2 13 are both in abutment with the composite plate and the plate strip to be tightened, thereby providing the required relative pressure.

[0037] In this embodiment, the length of the rod 11 is greater than the depth of the area of ​​the composite plates and plate strips to be fastened through the penetration, and the specific length should be maintained within 150% of the depth value of the area of ​​the composite plates and plate strips to be fastened to reduce the occurrence of bending or breaking caused by collision. The length of the protective tube 21 is greater than or equal to the depth of the area of ​​the composite plates and plate strips to be fastened through the penetration, thereby reducing the occurrence of direct contact between the rod 11 and the composite plates, thereby ensuring the life of the rod 11 for repeated use.

[0038] In this embodiment, the protection tube 21 is arranged perpendicular to the horizontal ground, so that the rod 11 in the protection tube 21 also maintains a nearly vertical state, so that when subjected to opposite pressure, a smaller oblique force component is generated, reducing the bending of the rod 11 and maintaining the service life of the rod 11.

[0039] Preferably, an implementation is provided, in which the rod 11 and the protection tube 21 are clearance-matched, the protection tube 21 is made of PVC plastic material, and the rod 11 is made of SUS301 stainless steel metal material. This implementation is low-cost and simple and easy to implement.

[0040] Preferably, another embodiment is provided, in which the rod 11 is a threaded rod, and the interior of the protective tube 21 is provided with threads. In this embodiment, the material of the protective tube 21 is PVC plastic, and the interior of the protective tube 21 is provided with a plurality of imitation metal threads having the same shape and size as the metal threads. The threaded rod and the protective tube 21 are threadedly connected via the imitation metal threads. This embodiment increases the cost to a certain extent but enables the threaded rod to maintain a state closer to vertical than the clearance fit in the protective tube 21, and at the same time strengthens the protective effect of the protective tube 21 on the threaded rod.

[0041] In this embodiment, the protective member 22 is made of channel steel, the length of the channel steel is greater than the length of the composite plate, and the length extension direction of the channel steel is parallel to the arrangement direction of the composite plate. The protective member 23 includes a mountain-shaped card and two steel pipes clamped in the mountain-shaped card. The two steel pipes are in contact with the template at the bottom of the composite plate. The pressure member 12 is a sealing nut. The surface of the channel steel in contact with the composite plate is the waist plate part. The waist plate part of the channel steel is provided with a hole, and the hole is aligned with the position through which the protective tube 21 passes. The sealing nut cooperates with the threaded section at one end of the rod 11 until the sealing nut is against the channel steel to provide a pressure in one direction. The pressure member 2 13 is an octagonal nut. The other end of the rod 11 passes through the mountain-shaped card. The octagonal nut cooperates with the threaded section of the rod 11 passing through the mountain-shaped card until it is against the mountain-shaped card to provide a pressure in one direction. The pressure one is opposite to the pressure two, thereby locking the composite plate and the plate strip template.

[0042] Preferably, an embodiment is provided, in which the protective member 22 is located at a higher spatial height than the protective member 23, and the pressure member 12 is located at a higher spatial height than the pressure member 2 13. The protective member 22 and the pressure member 12 cover the surface of one end of the rod 11 to isolate the one end of the rod 11 from contact with the outside world, that is, the channel steel is arranged on the top surface of the composite plate, and the sealing nut is welded in the hole on the channel steel waist plate. When the top threaded section of the rod 11 enters the sealing nut and fits, the bottom threaded section of the rod 11 fits with the octagonal nut until it contacts the mountain-shaped card. This method makes the top part of the rod 11 exposed at the top of the composite plate and more easily affected by construction personnel, construction equipment, and severe weather factors completely closed, thereby improving the service life of the rod 11 and facilitating the reuse of the hanging formwork bracket.

[0043] In the actual construction environment of this embodiment, after the construction personnel hoist the composite plate with holes on the plate strip template by crane, etc., they open holes in the plate strip to allow the rod 11 and the protective tube 21 to pass through the template and the composite plate, and match the threaded section of the rod 11 with the sealing nut on the channel steel at the top of the composite plate. After the steel pipe is set at the bottom of the composite plate, the mountain-shaped clamp is used for matching. Finally, after the threaded section of the rod 11 passes through the mountain-shaped clamp, the construction personnel use the octagonal nut to complete the matching. The threaded matching and abutment at both ends of the rod 11 lock the composite plate and the plate strip template, thereby reducing the problem of slurry leakage, reducing the waste of concrete and the cost of manual cleaning in the later stage, thereby obtaining more economical and environmentally friendly benefits. At the same time, during this period, due to the protection of the two ends of the rod 11, the rod 11 is not easily damaged. After the formwork is removed, the construction personnel release the matching of the threaded section of the rod 11 with the sealing nut and the octagonal nut, and take out the rod 11. At this time, the rod 11 can be quickly put into use next time, and the remaining holes can be relatively simply sealed by concrete injection, thereby obtaining the benefit of reuse.

[0044] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
