Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building engineering construction, especially a wall connecting structure for scaffold construction using structural bolt holes. BACKGROUND

[0002] When setting up a scaffold in a building engineering construction, it is inevitable to be connected with a nearby vertical structure. In particular, for the scaffold wall connecting structure near the side of a concrete wall, the traditional method needs to pre-bury a wall connecting piece, which has various forms, and generally, a connecting piece is pre-buried in the wall, and then the scaffold steel pipe is fixedly connected with the part of the connecting piece exposed to the wall.

[0003] For example, the wall connecting piece disclosed in Publication No. CN104963499A pre-buries a connecting bolt in the wall, and then fixes an angle steel on the side near the scaffold, and welds the scaffold steel pipe with the angle steel. When disassembling, the scaffold steel pipe needs to be cut off from the angle steel. Publication No. CN105317209A discloses another wall connecting piece, which still welds the scaffold steel pipe with the angle steel after moving the scaffold steel pipe to the lower part of the angle steel. Publication No. CN117758993A discloses another wall connecting piece, in which the pre-buried piece is fixed with a steel plate by expansion bolts, and then the scaffold steel pipe is directly welded on the steel plate. The detachable connection position of the above wall connecting pieces is not between the scaffold steel pipe and the pre-buried wall connecting piece, which affects the turnover efficiency of the scaffold steel pipe. The detachability is weak, and when disassembling, the scaffold steel pipe needs to be cut off from the connecting piece. Different pre-buried piece designs will separately open a hole in the wall, and the disassembling position of the pre-buried piece also needs to be repaired multiple times. SUMMARY

[0004] The utility model aims at providing a lengthened double screw scaffold wall connecting structure to solve the technical problem that the existing wall connecting piece pre-buries a connecting piece in the wall, and the detachable connection position is not between the scaffold steel pipe and the pre-buried wall connecting piece, which affects the turnover efficiency of the scaffold steel pipe, the detachability is weak, the scaffold steel pipe needs to be cut off from the connecting piece when disassembling, different pre-buried piece designs will separately open a hole in the wall, and the disassembling position of the pre-buried piece also needs to be repaired multiple times.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A lengthened double screw scaffold wall connecting structure, comprising a wall and a scaffold structure erected on the outer side of the wall, the scaffold structure and the wall being connected by a wall connecting assembly, the wall connecting assembly comprising a wall-penetrating tensioning screw, a first anchoring piece at the inner end of the wall-penetrating tensioning bolt, a steel pipe top plate on the outer side of the wall-penetrating tensioning bolt, a lengthened connecting screw, a limiting and fixing piece between the screws, a wall connecting steel pipe, a second anchoring piece at the outer end of the lengthened connecting screw, and a steel pipe fastener.

[0007] Tie rods are template tie rods used for reinforcing wall formwork. The inner end of the tie rod extends out of the inner side of the wall to form an inner end protrusion, and the outer end of the tie rod extends out of the outer side of the wall to form an outer end protrusion.

[0008] The inner protruding part is anchored to the inner surface of the wall by the first anchor, the steel pipe top plate is tightly attached to the outer surface of the wall, and the outer protruding part of the tie rod passes through the pre-reserved top plate hole on the steel pipe top plate.

[0009] The outer end of the tie rod and the inner end of the extended connecting rod are fixed together by a limiting fastener between the rods. The outer diameter of the wall-connecting steel pipe is smaller than the size of the top plate of the steel pipe, and the inner diameter of the wall-connecting steel pipe is larger than the outer contour size of the limiting fastener between the rods. The wall-connecting steel pipe is fitted over the extended connecting rod, the limiting fastener between the rods, and the outer end protrusion of the tie rod. The inner end face of the wall-connecting steel pipe is pressed against the outer surface of the top plate of the steel pipe. The outer end of the extended connecting rod extends out of the outer end of the wall-connecting steel pipe and is anchored to the outer end face of the wall-connecting steel pipe by a second anchor.

[0010] Steel pipe couplers include horizontal couplers and vertical couplers. Horizontal couplers are fastened to the wall-connecting steel pipes at the corresponding positions of the vertical steel pipes in the scaffolding structure.

[0011] The first anchor has the same structure as the second anchor, both including an anchor baffle and a butterfly clip from the inside out, with a baffle hole in the middle for the screw to pass through.

[0012] The first and second anchors also include anti-loosening nuts, which are located on the outside of the butterfly clip.

[0013] The screw-to-screw limiting fastener includes two limiting nuts that are fixedly connected as one piece, namely the first nut and the second nut.

[0014] The first nut is adapted to the size of the tie rod and is threaded to it, and the second nut is adapted to the size of the extended connecting rod and is threaded to it.

[0015] The connection between the first nut and the second nut can be configured in three ways: horizontally parallel, vertically aligned, or obliquely offset.

[0016] The first nut and the second nut are hexagonal nuts of the same size. The hexagonal nut includes six nut sides around its perimeter, and the nut sides of adjacent nut pairs are welded together.

[0017] The overlap length of the tie rod and the extended connecting rod inside the wall-connecting steel pipe shall not be less than 100mm.

[0018] The outer end of the extended connecting screw extends out of the outer end of the wall-connecting steel pipe by no less than 100mm.

[0019] Compared with the prior art, this utility model has the following features and beneficial effects:

[0020] This utility model designs a wall tie assembly, including tie rods, extension rods, and three baffles. The tie rods are used to reinforce the formwork during the construction of the main building structure. The extension rods are connected to the tie rods via inter-rod limiting fasteners. The baffles are located on the wall-facing side, the back wall side, and the end of the wall tie steel pipe, with pre-drilled holes in their bodies. The extension rods pass through the wall tie steel pipe and are connected to the baffles via butterfly clips. The wall tie assembly is connected to the scaffolding via fasteners to form a whole, thus facilitating the completion of a wall tie assembly.

[0021] In this invention, the pre-embedded tie rods are pre-installed in the concrete of the wall, allowing workers to use them as anchoring components for scaffolding without removing them during construction. A double-screw structure is designed, connecting the tie rods and extended screws via inter-screw limiting fasteners, forming an extended screw structure. The wall-connecting steel pipe is then fitted onto this extended screw structure. The first anchor is fixed to the inner side of the wall, and the second anchor is fixed to the outer end of the wall-connecting steel pipe, placing the tie structure on the outer side of the wall.

[0022] This utility model utilizes the bolt holes and screws used during the construction of the main building structure, eliminating the need for further pre-embedding and drilling. The wall tie assembly features a separate design for the wall tie steel pipe and tie bolts, allowing for disassembly and reconnection of each component. This significantly enhances disassembly and reusability, eliminating the need for steel cutting. The wall tie assembly adopts a tool-based design, making it convenient to use, highly manufacturable, and easy to operate. It can be prefabricated in a factory or fabricated on-site. The main connecting components are made of bolts, saving materials and allowing for adjustments based on site conditions. Attached Figure Description

Detailed Implementation

[0033] See the examples. Figures 1-3 As shown, an extended double-screw scaffold wall connection structure includes a wall 11 and a scaffold structure erected on the outside of the wall 11. The scaffold structure and the wall 11 are connected by a wall connection assembly. The wall connection assembly includes a through-wall tie rod 1, a first anchor 12 at the inner end of the through-wall tie rod, a steel pipe top plate 9 on the outer side of the through-wall tie rod, an extended connecting screw 6, a screw-to-screw limiting fastener 8, a wall connection steel pipe 5, a second anchor 13 at the outer end of the extended connecting screw 6, and a steel pipe fastener.

[0034] The tie rod 1 is a template tie rod for wall reinforcement template. The inner end of the tie rod 1 extends out of the inner side of the wall 11 to form an inner end protrusion, and the outer end of the tie rod 1 extends out of the outer side of the wall 11 to form an outer end protrusion.

[0035] The inner end protrusion is anchored to the inner surface of the wall 11 by the first anchor 12, the steel pipe top plate 9 is close to the outer surface of the wall 11, and the outer end protrusion of the tie rod 1 passes through the pre-reserved top plate hole on the steel pipe top plate 9.

[0036] The outer end of the tie rod 1 and the inner end of the extended connecting rod 6 are fixed by the limiting fastener 8 between the rods. The outer diameter of the wall-connecting steel pipe 5 is smaller than that of the steel pipe top plate 9, and the inner diameter of the wall-connecting steel pipe 5 is larger than the outer contour of the limiting fastener 8 between the rods. The wall-connecting steel pipe 5 is fitted over the extended connecting rod 6, the limiting fastener 8 between the rods, and the outer end of the tie rod 1. The inner end face of the wall-connecting steel pipe 5 is pressed against the outer surface of the steel pipe top plate 9. The outer end of the extended connecting rod 6 extends out of the outer end of the wall-connecting steel pipe 5 and is anchored to the outer end face of the wall-connecting steel pipe 5 by the second anchor 13.

[0037] The first anchor 12 and the second anchor 13 have the same structure, both including an anchor baffle 4 and a butterfly clip 2 from the inside out. The anchor baffle 4 has a baffle hole in the middle for the screw to pass through. The first anchor 12 and the second anchor 13 also include an anti-loosening nut 3, which is located on the outside of the butterfly clip 2 to prevent slippage.

[0038] The screw-to-screw limiting fastener 8 includes two limiting nuts fixedly connected as one piece, namely a first nut 81 and a second nut 82. The first nut 81 is adapted to the size of the pull screw 1 and is threadedly connected to it, and the second nut 82 is adapted to the size of the extended connecting screw 6 and is threadedly connected to it. In this embodiment, the pull screw 1 and the extended connecting screw 6 have the same diameter.

[0039] In this embodiment, see Figures 4-7 As shown, the first nut 81 and the second nut 82 are hexagonal nuts of the same size, identical to the anti-loosening nut 3. Each hexagonal nut comprises six circumferential nut sides, with adjacent nut sides welded together. The connection between the first nut 81 and the second nut 82 can be either horizontally parallel, vertically aligned, or obliquely staggered. These three connection methods arise from the different angles formed by the two nuts during installation.

[0040] In this embodiment, the overlap length of the tie rod 1 and the extended connecting rod 6 within the wall-connecting steel pipe 5 is not less than 100mm. The outer end of the extended connecting rod 6 extends out of the outer end of the wall-connecting steel pipe 5 by a length of not less than 100mm. The anchoring baffle 4 and the top plate 9 of the steel pipe are both 100mm×100mm×10mm steel plates, with holes reserved for a diameter not less than that of the tie rod.

[0041] See Figure 8 As shown, the steel pipe coupler 7 includes a horizontal coupler 71 and a vertical coupler 72. The horizontal coupler 71 is fastened to the wall-connecting steel pipe 5 at the position corresponding to the vertical steel pipe 10 of the scaffold structure, thereby connecting with the scaffold structure to form an integral whole. See [reference needed]. Figure 1 The middle part is connected to the vertical support pipe 14 in the scaffolding structure.
