Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for building construction, specifically a wall-connecting component for shear walls of external scaffolding. Background Technology

[0002] During shear wall construction, a scaffolding steel pipe with a diameter of 48.3mm is usually pre-embedded inside the shear wall. One end of the scaffolding steel pipe protrudes to the outside of the shear wall. The horizontal bars on the external scaffolding are connected to the protruding end of the scaffolding steel pipe to the outside of the shear wall by fasteners, so that workers can carry out construction operations on the external scaffolding.

[0003] However, because the scaffolding steel pipes are hollow, liquid inside the shear wall may leak out later, causing water seepage. Furthermore, the end of the scaffolding steel pipe protruding beyond the shear wall needs to be cut off by workers using a cutting machine after the shear wall construction is completed, causing inconvenience and unnecessary material waste. Therefore, it is necessary to design a wall-tying device that facilitates the connection between the external scaffolding and the shear wall.

[0004] Therefore, this application proposes a wall tie assembly for shear walls in external scaffolding. Utility Model Content

[0005] The purpose of this utility model is to provide a wall-connecting component for shear walls of external scaffolding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A wall tie assembly for shear walls in external scaffolding includes:

[0008] The embedded part is pre-embedded and installed in the shear wall;

[0009] The telescopic part is connected to the embedded part, and the length of the connection part with the embedded part is adjustable, so that the end of the telescopic part is flush with the outer wall of the shear wall.

[0010] A connecting steel pipe is provided, which is detachably connected to the telescopic part, and the end away from the telescopic part is connected to the external scaffolding via an external fastener.

[0011] Furthermore, the embedded part includes a baffle, the thickness direction of which is perpendicular to the surface of the shear wall.

[0012] Furthermore, the telescopic part includes:

[0013] A fixing sleeve is fixedly connected to one side of the baffle in the thickness direction;

[0014] A threaded post, wherein the threaded post is coaxially threaded through the fixed sleeve.

[0015] Furthermore, the baffle is provided with a plurality of ribs extending to the fixing sleeve.

[0016] Furthermore, the threaded post is coaxially provided with an installation hole for the connecting steel pipe to pass through freely, and a quick-release structure is provided between the threaded post and the wall of the installation hole.

[0017] Furthermore, the quick-release structure includes a protrusion fixed to one end of the connecting steel pipe that passes through the mounting hole. The mounting hole wall is provided with a stop groove for the protrusion to engage. The stop groove includes a first stop groove and a second stop groove in sequence along the direction away from the baffle. The first stop groove and the second stop groove are connected end to end and are perpendicular to each other. The length direction of the second stop groove is parallel to the axial direction of the mounting hole. The protrusion slides freely in the first stop groove and the second stop groove.

[0018] Furthermore, the protrusion is provided in two parts and arranged in an array along the axial direction of the connecting steel pipe.

[0019] Furthermore, the connecting steel pipe is provided with a stop structure, which is used to restrict the circumferential rotation of the connecting steel pipe after the protrusion is engaged in the first stop groove.

[0020] Furthermore, the stop structure includes:

[0021] A sliding ring is sleeved on the connecting steel pipe and slides freely on the connecting steel pipe. The sliding ring is keyed to the connecting steel pipe. A blind hole is provided at the end of the threaded post away from the baffle for the sliding ring to pass through freely.

[0022] The locking block is fixed to the periphery of the connecting steel pipe, and the wall of the blind hole is provided with a locking groove for the locking block to engage, and the locking block can slide freely in the locking groove.

[0023] Furthermore, a fixing ring is fitted onto the connecting steel pipe, and a spring is wound around the connecting steel pipe, with the two ends of the spring elastically abutting against the fixing ring and the sliding ring respectively.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This utility model features a pre-embedded part, which is pre-installed within the shear wall and connected to a connecting steel pipe via an expansion joint. The pre-embedded part is enclosed, thereby reducing water seepage at the contact point between the pre-embedded part and the shear wall. Furthermore, since the length of the connection between the expansion joint and the pre-embedded part is adjustable, the end face of the expansion joint can be flush with the outer wall of the shear wall. This eliminates the need for workers to cut the expansion joint protruding to the outside of the shear wall, making the operation more convenient and preventing material waste.

[0026] This utility model sets protrusions that sequentially engage with the second sliding groove and the first sliding groove, so that after the connecting steel pipe is inserted into the mounting hole of the threaded column, it can be rotated at a certain angle to prevent the connecting steel pipe from being pulled out of the mounting hole of the threaded column, thereby facilitating the quick connection between the connecting steel pipe and the threaded column.

[0027] This invention features a sliding ring that engages with the blind hole and a locking block that engages with the slot. This prevents the locking block on the connecting steel pipe from rotating circumferentially after it engages with the first sliding groove, thus avoiding loosening of the connecting steel pipe in the mounting hole of the threaded column.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figures 1-4 This utility model provides a technical solution: a wall-connecting component for shear walls in external scaffolding, including a baffle 1 pre-embedded and installed in the shear wall. The baffle 1 has a disc-shaped outline and is vertically positioned within the shear wall, meaning that the thickness direction of the baffle 1 is parallel to the thickness direction of the shear wall, or in other words, the thickness direction of the baffle 1 is perpendicular to the surface of the shear wall. A fixing sleeve 2 is coaxially welded to the baffle 1. The fixing sleeve 2 is hollow inside and has internal threads. A threaded post 3 is installed inside the fixing sleeve 2, and the external threads on the threaded post 3 are engaged with the internal threads inside the fixing sleeve 2. In this configuration, the end of the threaded column 3 away from the baffle 1 can be flush with the outer wall of the shear wall or slightly protrude to the outside of the shear wall. The threaded column 3 has a blind hole 10 coaxially opened inside, and a connecting steel pipe 6 is coaxially telescopically inserted into the mounting hole 10. A fastener (not shown in the figure) is installed at one end of the connecting steel pipe 6 that passes through the mounting hole 10. The fastener is connected to the crossbar on the external scaffold, so that the scaffold and the connecting steel pipe 6 can be connected. The baffle 1 has multiple stiffening plates extending to the fixing sleeve 2 to reinforce the connection between the baffle 1 and the fixing sleeve 2.

[0035] Two protrusions 13 are welded to the periphery of one end of the connecting steel pipe 6 that passes through the mounting hole 10. The two protrusions 13 are arranged in an array along the axial direction of the connecting steel pipe 6. Two stop grooves are opened on the wall of the mounting hole 10. The stop grooves include a first stop groove 14 and a second stop groove 11 in sequence along the direction away from the baffle 1. The first stop groove 14 and the second stop groove 11 are connected end to end and are perpendicular to each other. The length direction of the second stop groove 11 is parallel to the axial direction of the mounting hole 10. The protrusions 13 are engaged in the first stop groove 14 and the second stop groove 11 and can slide freely in the first stop groove 14 and the second stop groove 11.

[0036] Insert the end of the connecting steel pipe 6 into the mounting hole 10, and make the protrusion 13 first engage in the second stop groove 11. Slide along the inner wall of the second stop groove 11 to the connection between the first stop groove 14 and the second stop groove 11. The connection between the first stop groove 14 and the second stop groove 11 is an arc transition, so that the protrusion 13 will slide from the arc transition part into the first stop groove 14. During the sliding process, by rotating the connecting steel pipe 6, the protrusion 13 can be smoothly engaged in the first stop groove 14, so that the connecting steel pipe 6 will not be pulled out from the mounting hole 10.

[0037] A sliding ring 4 that can slide freely is fitted onto the connecting steel pipe 6. The sliding ring 4 is keyed to the connecting steel pipe 6. A blind hole 8 is opened at the end of the threaded column 3 away from the baffle 1, allowing the sliding ring 4 to pass freely. Two locking blocks 12 are welded on the periphery of the connecting steel pipe 6. The hole wall of the blind hole 8 is provided with a locking groove 9 for the locking blocks 12 to engage. The locking blocks 12 slide freely in the locking groove 9. A fixing ring 5 is fitted onto the connecting steel pipe 6. A spring 7 is wound around the connecting steel pipe 6. The two ends of the spring 7 elastically abut against the fixing ring 5 and the sliding ring 4 respectively. The spring 7 is in a certain degree of compression, so that the spring 7 elastically abuts against the sliding ring 4, thereby causing the locking blocks 12 to engage in the locking groove 9.

[0038] When inserting the connecting steel pipe 6 into the mounting hole 10, first move the sliding ring 4 towards the fixing ring 5, so that the sliding ring 4 compresses the spring 7. When the spring 7 is in a compressed state, the protrusion 13 engages in the first stop groove 14. Then release the sliding ring 4. Under the elastic force of the spring 7, the sliding ring 4 will move towards the blind hole 8, so that the locking block 12 engages in the locking groove 9. At this time, since the sliding ring 4 is keyed to the connecting steel pipe 6 and the locking block 12 engages with the locking groove 9, the connecting steel pipe 6 will not rotate circumferentially after the protrusion 13 on the connecting steel pipe 6 engages in the first stop groove 14, thus ensuring the stability of the connecting steel pipe 6 and the threaded column 3 after installation.

[0039] The working principle of this utility model is as follows: The end of the connecting steel pipe 6 is inserted into the mounting hole 10, and the protrusion 13 is first engaged in the second stop groove 11. It slides along the inner wall of the second stop groove 11 to the connection between the first stop groove 14 and the second stop groove 11. The connection between the first stop groove 14 and the second stop groove 11 is in the shape of an arc transition, so that the protrusion 13 will slide from the arc transition part into the first stop groove 14. During the sliding process, by rotating the connecting steel pipe 6, the protrusion 13 can be smoothly engaged in the first stop groove 14, so that the connecting steel pipe 6 will not be pulled out from the mounting hole 10.

[0040] When inserting the connecting steel pipe 6 into the mounting hole 10, first move the sliding ring 4 towards the fixing ring 5, so that the sliding ring 4 compresses the spring 7. When the spring 7 is in a compressed state, the protrusion 13 engages in the first stop groove 14. Then release the sliding ring 4. Under the elastic force of the spring 7, the sliding ring 4 will move towards the blind hole 8, so that the locking block 12 engages in the locking groove 9. At this time, since the sliding ring 4 is keyed to the connecting steel pipe 6 and the locking block 12 engages with the locking groove 9, the connecting steel pipe 6 will not rotate circumferentially after the protrusion 13 on the connecting steel pipe 6 engages in the first stop groove 14, thus ensuring the stability of the connecting steel pipe 6 and the threaded column 3 after installation.
