Description

A new type of wall connection suitable for concrete

Technical Field

The utility model relates to the technical field of building construction, in particular to a new wall connecting piece suitable for concrete.

Background Art

During construction, steel pipe scaffolding is usually erected outside the building. In order to make the scaffolding have reliable anti-overturning measures, a wall connection structure is usually set up, which can enhance the overall stability of the scaffolding, improve the scaffolding's stable bearing capacity and avoid major accidents such as toppling or collapse of the scaffolding.

The wall-connecting structure of the ground-type clip-on steel pipe scaffolding, referred to as the wall-connecting part, is generally divided into a rigid wall-connecting structure and a flexible wall-connecting structure. The wall-connecting parts specified in the current "Safety Technical Specifications for Clip-on Steel Pipe Scaffolding in Construction" are rigid wall-connecting parts. In view of the drawbacks of the most commonly used wall-connecting parts, the company's prior patent CN220184608U discloses a wall-connecting part suitable for plain concrete, which solves the technical problem that the existing wall-connecting parts will have adverse effects on the plain concrete finish and affect the installation of curtain walls. However, since the screw rod in this solution passes through both ends of the wall-connecting steel pipe, the required length of the screw rod is relatively long. When the outer wall space is limited, the wall-connecting part is not convenient to install and disassemble.

Please refer to Figures 1 to 4. A new type of wall connecting member suitable for concrete is provided in the embodiment of the present application, which is connected between the main structure and the scaffolding 2, including a wall connecting rod 3, a connecting fastener 4, a bolt rod 5 and a fastener 6; the wall connecting rod 3 is fixed on the scaffolding 2, and a pre-embedded sleeve 7 is provided in the main structure. The connecting fastener 4 is fixed to one end of the wall connecting rod 3 facing the main structure, and the fastener 6 is located on the side of the main structure away from the scaffolding 2. The bolt rod 5 passes through the connecting fastener 4 and the pre-embedded sleeve 7 and is fixed to the main structure through the fastener 6.

It should be noted that the embedded sleeve 7 in the main structure of this embodiment is embedded when the concrete casting template is erected to serve as the casting template tension bolt hole, and the diameter of the embedded sleeve 7 can be 25mm. This solution uses the concrete tension bolt hole to set the wall connection piece, does not need to embed steel pipes, does not occupy the floor facade space, does not affect the construction work surface, and does not affect the curtain wall installation when the exterior wall is constructed at the wall connection piece position, effectively ensuring the construction progress.

According to some embodiments of the present application, the connecting fastener 4 includes a buckle seat 41, a buckle ring 42, a buckle ring bolt 43 and a buckle ring nut 44, the buckle seat 41 and the buckle ring 42 have relative semicircular grooves, the two semicircular grooves are used to jointly clamp the outer peripheral wall of the wall connecting rod 3, one end of the buckle ring 42 is movably hinged to the buckle seat 41, one end of the buckle ring bolt 43 is connected to the buckle seat 41, and the other end passes through the free end of the buckle ring 42, the buckle ring nut 44 is arranged on the buckle ring bolt 43 to make the buckle ring 42 approach the buckle seat 41, and a fixing hole 411 is provided on the buckle seat 41, which passes through the buckle seat 41 in the thickness direction, and the axis of the fixing hole 411 is parallel to the axis of the semicircular grooves on the buckle seat 41 and the buckle ring 42, and the bolt rod 5 is inserted into the fixing hole 411 to press the connecting fastener 4 onto the main structure.

According to some embodiments of the present application, one end of the retaining ring bolt 43 is movably hinged with the buckle seat 41, and the free end of the retaining ring 42 is provided with a U-shaped groove adapted to the retaining ring bolt 43, and the opening direction of the U-shaped groove corresponds to the rotation direction of the retaining ring bolt 43. When the connecting fastener 4 is fixedly connected to the wall connecting rod 3, the rod body of the retaining ring bolt 43 is located in the U-shaped groove. Through the above arrangement, when it is necessary to separate the connecting fastener from the wall connecting rod, it is only necessary to first loosen the retaining ring nut, and then rotate the retaining ring bolt to disengage it from the U-shaped groove, so that the buckle can be turned around the buckle seat, thereby removing the wall connecting rod, and the retaining ring bolt and the retaining ring nut do not need to be completely separated, which is conducive to improving the installation and disassembly efficiency of the wall connecting rod.

According to some embodiments of the present application, the fastener 6 is provided with a pad 8 on the side facing the main structure, and the pad 8 can be made of a galvanized steel plate. By providing the pad, on the one hand, the contact area between the fastener and the concrete surface can be increased, so that the main structure can evenly bear the pressure and prevent loosening; on the other hand, the concrete surface can be protected from damage.

According to some embodiments of the present application, the size of the pad 8 is larger than the radial size of the fastener 6. Specifically, the pad 8 may be 200*200 mm in size and 5 mm in thickness. This design ensures that the fastener does not directly contact the concrete wall surface, thereby avoiding damage to the concrete wall surface.

According to some embodiments of the present application, the scaffold 2 includes a vertical pole 21, a small cross bar 22 and a large cross bar 23, and the small cross bar 22 and the large cross bar 23 are fixed on the vertical pole 21. Specifically, the vertical pole 21, the small cross bar 22 and the large cross bar 23 are fixedly connected by fasteners. It should be noted that the fasteners can be commonly used fasteners in the prior art.

According to some embodiments of the present application, the small crossbar 22 is arranged above the large crossbar 23, and the small crossbar 22 and the large crossbar 23 are staggered and connected in a grid shape. Specifically, the vertical rod 21 is arranged in the vertical direction, the large crossbar 23 is arranged in the horizontal direction and parallel to the facade of the main structure, and the small crossbar 22 is arranged in the horizontal direction and perpendicular to the facade of the main structure.

It should be noted that the above is the structural composition of a conventional scaffold. Of course, scaffolds with other structures can also be used, which will not affect the installation and use of the wall connecting parts in this embodiment.

According to some embodiments of the present application, the fastener 6 is a nut that matches the bolt rod 5. Specifically, the fastener 6 may include two nuts, and the bolt rod 5 may be an M16 hexagonal common bolt rod. By arranging two nuts at the tail end of the bolt rod, a certain loosening effect can be achieved to ensure that the scaffold is stably connected to the main structure.

According to some embodiments of the present application, the wall connecting rod 3 is fixed to the scaffold 2 by a fastener. Specifically, the wall connecting rod 3 can be a steel pipe. It should be noted that the fastener can be a fastener commonly used in the prior art.

According to some embodiments of the present application, the main structure includes a wall column structure 1 and a beam structure 9 .

The novel wall connecting member in the embodiment of the present application has at least the following advantages:

1. Use the location of the tension bolt holes on the gable and side beams of the wall connection parts on the scaffolding layout diagram to effectively use the tension bolt holes on the main structure to install the wall connection parts. There is no need to drill additional holes in the main structure, which greatly reduces the amount of repair work in the later stage.

2. The use of this wall connection piece does not occupy the external facade space of the floor, does not affect the construction work surface, speeds up the construction progress, and does not affect the curtain wall installation when the external wall construction is carried out at the location of the wall connection piece, and avoids the need to pass through the wall for installation twice, thereby effectively preventing the occurrence of water seepage and leakage in the external wall. In the later stage, only the tension bolt holes at the location of the steel pipe against the structure need to be repaired;

3. This wall tie has a simple structure and is easy to install and disassemble, saving time. The wall tie can be disassembled by simply removing the nut. The parts can be reused after disassembly and can be recycled between different projects. Compared with traditional steel pipes, steel bars and flat steel wall ties, it saves materials and costs and effectively protects the concrete structure.

4. The wall connection is firm and reliable, with high rigidity, and can bear and transmit tensile and compressive bidirectional loads, significantly improving the overall stability of the scaffolding;

5. Compared with conventional wall ties that are buried on the top of beams, which affect the construction of exterior walls such as masonry, plastering, and coating, the eyelets formed by embedded parts need to be repaired, and the wall ties need to be reinstalled for the second time. Compared with traditional technology, this wall tie reduces some processes, saves steel, reduces safety hazards, and eliminates the common quality problem of leakage at the exterior wall openings;

6. Compared with other wall ties, this wall tie is more tool-based. It does not require the installation of embedded parts in advance during the main structure construction, which effectively avoids the situation where the wall tie cannot be installed and used due to the installation deviation of embedded parts. After the traditional wall tie is disassembled, it is necessary to cut the embedded steel pipe or embedded bolts. This wall tie does not require this process, which is faster and safer.

The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
