[0002] In the process of general construction projects, scaffolding, safety ladders, tower cranes and other facilities involving climbing or going down wells need to be equipped with wall-mounted devices after exceeding a certain free height to ensure the stability and reliability of such facilities during use; the device structure of traditional wall-mounted parts is not strong enough or is difficult to remove or handle in the later stage, which can easily cause defects in the appearance quality of the wall or other attached structures or damage to the finished structure, which is not conducive to project construction.

[0003] At present, most of the wall-attached parts in China are mostly fixed with embedded steel plates, which are anchored in the wall or concrete structure by surface welding of steel bars. This method is easily affected by the welding quality and concrete strength. The embedded steel plates are easily damaged or have insufficient adhesion, and there is a situation where the steel plates are detached from the wall, causing the wall-attached facilities to become unstable, posing a great safety risk. Some sites also use through-rod fixation, but when the wall structure is too large, the through-rod function is not available, and it is not conducive to on-site development.

[0004] In order to solve the above technical problems, the utility model designs a novel screw-in wall-attached connector device. Utility Model Content

[0006] The utility model achieves the above technical objectives through the following technical means.

[0007] A screw-in wall-attached connector device comprises a cone anchor, a screw-in anchor pin and an embedded part. The embedded part is embedded in the wall and is detachably connected to the cone anchor to achieve wall-attaching force transmission in the wall.

[0008] Furthermore, the screw-in anchor pin includes a pin rod and a bayonet pin. A groove is provided on the surface of the pin rod. The bayonet pin is embedded in the groove on the pin rod and can rotate around the pin rod. After rotation, the bayonet pin can fully fit with the pin rod. Between the bayonet pin and the pin rod, one end of the bayonet pin is connected to the pin rod by a pin shaft to achieve rotation, and the other end of the bayonet pin is connected to the pin rod by a spring.

[0009] Furthermore, one end of the cone anchor is a truncated cone structure, a circular hole is provided in the truncated cone structure, and a slot matching the size of the bayonet is provided in the circular hole.

[0010] Furthermore, the other end of the cone anchor is a cylindrical structure, a circular hole is also opened in the cylindrical structure, and the inner wall of the circular hole is provided with an internal thread; the embedded parts include an anchor rod, an anchor plate, and a nut. The anchor plate is a plate-shaped structure, and the inner wall of the through hole in the middle is provided with an internal thread, and both ends of the anchor rod are provided with external threads. One end of the anchor rod is screwed into the cylindrical structure of the cone anchor to achieve threaded connection with the cone anchor, and the other end is screwed into the anchor plate and then extends out and is threadedly connected with the nut.

[0011] Furthermore, when the screw-in anchor pin is screwed into the slot in the cone anchor, the spring is in an extended state; when the screw-in anchor pin is screwed out of the slot in the cone anchor, the spring is in a compressed state.

[0012] The utility model has the following beneficial effects:

[0013] The utility model utilizes the embedded parts embedded in the wall to connect the cone anchor through the anchor rod, so as to realize the transmission of the wall attachment force in the wall.

The card pin of the screw-in anchor pin is smoothly locked in the cone anchor card slot when it is screwed into the cone anchor, so as to realize the transmission of the adhesion force. When it is finally removed, the screw-in anchor pin is screwed out and the cone anchor is rotated out of the wall, without causing any damage to the wall, and it is convenient to repair the remaining cone anchor hole on site, and the construction efficiency is high. Moreover, the screw-in wall attachment connector device designed by the utility model has the materials needed for processing which are relatively common on the construction site, the materials are convenient to obtain, the structure is simple, and it can be processed and manufactured by itself.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present utility model is not limited thereto.

[0021] As Figures 1 to 5 shown, a screw-in type wall-attached connecting piece device described in the present utility model includes a tapered anchor 5, a screw-in type anchor pin and a pre-embedded part. The screw-in type anchor pin includes a pin rod 1 and a retaining pin 2; the pre-embedded part includes an anchor rod 6, an anchor backing plate 7 and a nut 8.

[0022] As Figure 1 shown, the anchor backing plate 7 is of a plate-like structure, and the inner wall of the through hole in the middle is provided with internal threads; one end of the tapered anchor 5 is of a conical frustum structure, and the other end is of a cylindrical structure. A round hole is opened in the conical frustum structure, and a card slot 9 matching the size of the retaining pin 2 in the screw-in type anchor pin is opened in the round hole. The size of the card slot 9 is more than 1 mm larger than the size of the retaining pin 2. A round hole is also opened in the cylindrical structure, and the inner wall of the round hole is provided with internal threads.

[0023] As Figure 1 shown, external threads are provided at both ends of the anchor rod 6. One end of the anchor rod 6 is screwed into the cylindrical structure of the tapered anchor 5 to realize threaded connection with the tapered anchor 5, and the other end is screwed into the anchor backing plate 7 and then extends out and is threadedly connected with the nut 8. Among them, the anchor backing plate 7 is anchored in the wall through the nut 8 arranged behind it to realize the force application of the wall attachment.

[0024] As Figures 2 to 5 shown, a groove is opened on the surface of the pin rod 1, and the retaining pin 2 is completely embedded and installed in the groove on the pin rod 1 and can rotate around the pin rod 1. After rotation, the retaining pin 2 can be completely attached to the pin rod 1; specifically, between the retaining pin 2 and the pin rod 1, one end of the retaining pin 2 is connected to the pin rod 1 by a pin shaft 4 to realize rotation, and the other end of the retaining pin 2 is connected to the pin rod 1 by a spring 3. To prevent the spring 3 from detaching from the retaining pin 2 and the pin rod 1, it is required that both ends of the spring 3 must be fixedly connected to the retaining pin 2 and the pin rod 1.

[0025] As Figure 5 shown, when the screw-in type anchor pin is screwed into the card slot 9 in the tapered anchor 5, the spring 3 is in a stretched state.

[0026] As Figure 4 shown, when the screw-in type anchor pin is screwed out of the card slot 9 in the tapered anchor 5, the spring 3 is in a compressed state.

[0027] In order to facilitate the attachment of other types of facilities and equipment to the wall, the exposed end of the screw-in anchor pin can be a connected screw head, a lifting ring or any other connector that can achieve any connection function. The specific setting can be based on the structural requirements of the facilities and equipment to be attached to the wall.

[0028] The working principle of the screw-in wall-attached connector device is: using the embedded parts embedded in the wall, the cone anchor 5 is connected through the anchor rod 6 to realize the wall-attaching force transmission in the wall. After the wall construction is completed, the cone anchor 5 exposed on the surface is used as the attachment point of the next wall-attached facility. The locking pin 2 of the screw-in anchor pin is smoothly locked in the locking groove 9 of the cone anchor 5 when screwed into the cone anchor 5, realizing the adhesion force transmission; when finally dismantled, the screw-in anchor pin is unscrewed, and the cone anchor 5 is rotated out of the wall, without causing any damage to the wall, and it is convenient to repair the remaining cone anchor hole on site, with high efficiency and less damage to the wall surface.

[0029] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
