Description

Technical Field

[0001] The utility model relates to the field of scaffolding installation, in particular to an axially telescopic wall connecting member and a socketed disc type steel pipe scaffolding. Background Art

[0002] The socketed disc type steel pipe scaffolding has been widely used as a working scaffold due to its high bearing capacity and strong durability. To ensure the stability of the working scaffold, wall connecting members are often required. Therefore, in construction projects, wall connecting members are usually applied to the connection and fixation between the outer scaffold and the structural wall, which is of great significance for the safe construction of buildings. The traditional wall connecting member is often connected to the main structure by means of embedded steel pipes and embedded bolts, and is connected to the outer scaffold upright by means of fasteners. However, according to the different functions of the outer scaffold, the distance between the outer scaffold and the wall is not the same. Therefore, wall connecting rods of different lengths need to be equipped to realize the connection between the wall and the scaffold, which directly leads to an increase in accessories, not only increasing the production and manufacturing cost of the scaffold, but also making the procedures cumbersome during the initial installation and the later removal of the scaffold. Moreover, the commonly used adjusting mechanism has a radial gap, which causes the wall connecting member to shake during use, resulting in inaccurate position positioning and easy loosening of the connection, making the wall connecting member easy to disengage from the scaffold and causing unreliable connection. In addition, due to the excessive number of loose parts of the traditional scaffold, some are easy to be lost, resulting in waste.

[0003] Therefore, there is an urgent need for a wall connecting member that can quickly adjust the length according to requirements, has reliable connection, is convenient for disassembly and assembly, and has low cost. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides an axially telescopic wall connecting member and a socketed disc type steel pipe scaffolding, which are used to solve the problems that the existing wall connecting member can quickly adjust the length according to requirements, has accurate positioning, reliable connection, is convenient for disassembly and assembly, and has low cost.

[0005] To achieve the above object and other related objects, the utility model provides an axially telescopic wall connecting member, which includes a horizontal wall connecting rod and horizontal connecting screw rods detachably arranged at both ends of the horizontal wall connecting rod. The horizontal wall connecting rod is of a hollow tubular structure. The inner ends of two sets of the horizontal connecting screw rods are coaxially inserted into the horizontal wall connecting rod respectively and are threadedly connected with the horizontal wall connecting rod. A buckle head is arranged at the outer end of each horizontal connecting screw rod. The two buckle heads are respectively connected with the embedded parts buried in the edge members of the building main structure and the socketed disc type upright by means of plug-in fixing parts. The buckle head has a buckle slot in a C shape or a U shape. Positioning holes for inserting the plug-in fixing parts are reserved on two juxtaposed upper and lower slot walls of the buckle slot and are aligned up and down. The plug-in fixing part is in a strip shape. Both ends of the plug-in fixing part are bent towards the same side to form a plug-in part and an anti-disengagement bending part. The plug-in part is in a wedge shape and is adapted to the shape of the positioning hole.

[0006] Preferably, the horizontal wall connecting rod includes a hollow rod body with both ends passing through and a fastening mechanism arranged at the end of the hollow rod body. The fastening mechanism has an internal threaded hole for a horizontal connecting screw rod to pass through and to cooperate with the horizontal connecting screw rod thread. The outer wall of the horizontal connecting screw rod is provided with an external thread for cooperating with the internal thread.

[0007] Preferably, the horizontal wall connecting rod is a screw threaded sleeve adapted for the horizontal connecting screw rod, the inner wall ring of the horizontal wall connecting rod is provided with an internal thread, and the outer wall of the horizontal connecting screw rod is provided with an external thread for cooperating with the internal thread, and the horizontal wall connecting rod and the horizontal connecting screw rod are connected by cooperating internal threads and external threads.

[0008] Preferably, the fastening mechanism is a jacking nut or a screw nut.

[0009] Preferably, the horizontal connecting screw rod is a hollow screw rod.

[0010] Preferably, the plug-in portion has a wedge-shaped plug-in bevel and a plug-in straight edge that are arranged opposite to each other, and the distance between the wedge-shaped plug-in bevel and the plug-in straight edge decreases gradually from top to bottom.

[0011] Preferably, the plug-in portion and the anti-slip bending portion are integrally formed with a smooth transition.

[0012] Preferably, the inner bending angle α of the plug-in portion and the anti-slip bending portion is 130-160°, and the outer bending angle β of the plug-in portion and the anti-slip bending portion is 130-160°.

[0013] More preferably, the inner bending angle α of the plug-in portion and the anti-slip bending portion is 150°, and the outer bending angle β of the plug-in portion and the anti-slip bending portion is 150°.

[0014] Preferably, a through hole is provided at the bottom of the anti-slip bending portion.

[0015] The utility model describes a socket-and-spigot type disc-type steel pipe scaffold, comprising the axial telescopic wall connection member, disc-type vertical pole and embedded member, wherein the embedded member is embedded in the edge member of the main structure of the building, the outer end of the embedded member falling on the edge member is provided with a plug-in buckle piece inserted in a buckle slot, and the center of the plug-in buckle piece is provided with a plug-in hole for the plug-in fixing member to pass through, the two buckle joints of the axial telescopic wall connection member buckle the plug-in buckle piece and the buckle plate of the disc-type vertical pole respectively, and are plugged in through the corresponding plug-in fixing members.

[0016] Advantageously, a set of horizontal connecting screw rods are inserted at each end of the horizontal wall connecting rod of the utility model, and the horizontal connecting screw rods are threadedly connected to the horizontal wall connecting rods to realize the expansion and contraction of the axial direction of the axial telescopic wall connecting member. A buckle joint is configured at one end of each set of horizontal connecting screw rods, so that buckle joints are configured at both ends of the axial telescopic wall connecting member, one of which is connected to the embedded part pin embedded in the edge member of the main structure of the building through the plug-in fixing piece, and the other buckle joint is connected to the buckle plate pin of the buckle type vertical rod through the plug-in fixing piece.

[0017] More advantageously, according to the different distances of the external scaffoldings with different functions from the wall, the insertion depth of the horizontal connecting screw rod is adjusted, thereby realizing the axial extension and contraction of the axial telescopic wall connecting piece to adapt to the different distances between the wall to be connected and the scaffolding, and having excellent applicability. Moreover, the axial telescopic wall connecting piece of the utility model adopts a latch-type structure connection, and is connected to the embedded parts and the disc-type vertical poles buried in the edge components of the main structure of the building through the mutually plugged buckle joints and the plug-in fixings. Since the two ends of the plug-in fixing are bent to the same side to form a plug-in part and an anti-drop bending part, the plug-in part is wedge-shaped and matches the shape of the positioning hole, so that the plug-in fixing will not fall out of the connection. This structure not only ensures that the tensile and compressive bearing capacity of the wall connecting piece can meet the construction needs, but also prevents the plug-in fixing from falling out, improves the reliability of the connection, and effectively ensures the stability of the frame; when the frame is dismantled in the later stage, it can be recycled, and has good applicability and economy.

[0018] The benefits of the utility model are: 1. The axial length of the wall connecting piece can be adjusted in both directions, and the stroke is effectively adjusted to meet the needs of scaffolds with different functions; 2. The wall connecting piece is connected to the embedded parts and the disc-type vertical poles through mutually plug-in buckle joints and plug-in fixings. It has high pull-out bearing capacity and convenient connection. It only needs a hammer to tighten the pins to ensure reliable connection. The construction efficiency is high and the tensile bearing capacity is high. The specially designed wedge-shaped latch piece can effectively prevent it from falling out during use, thereby improving safety; 3. The horizontal connecting screw rod and the horizontal wall connecting rod are fixed by a fastening mechanism, which can compensate for the radial gap between the horizontal connecting screw rod and the horizontal wall connecting rod, prevent the horizontal connecting screw rod from radial offset, and accurately position; 4. High economy: when the external scaffold is dismantled, the plug-in fixings of the wall connecting piece are uniformly connected to prevent the loss of accessories, which is highly economical.
