Description

Technical Field

[0001] The utility model relates to the technical field of engineering, in particular to a detachable and length-adjustable pre-buried disc-buckle scaffolding wall connecting piece. Background Art

[0002] Traditional scaffolding wall ties require a short steel pipe to be embedded in the concrete before pouring the concrete structure. When the frame is erected, the horizontal steel pipe is connected to the frame upright with fasteners. After the scaffold is used, the embedded short steel pipe needs to be cut off with a cutting machine, and the cut hole is filled with concrete. In this way, the workload of concrete filling is large, and the steel pipe embedded in the concrete after the wall tie is cut cannot be recycled and reused; and because buildings usually have multiple planes, the length of the wall tie is not uniform, and it needs to be cut and adjusted according to the actual length of the construction site, which wastes steel. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects and propose a detachable and length-adjustable embedded disc-type scaffolding wall connection part, which can avoid the need to embed short steel pipes and only requires one cylindrical nut to be embedded. No cutting is required for later disassembly, which can reduce the workload of blocking, and the remaining materials can be recycled to save costs.

[0004] In order to achieve the above object, the utility model is achieved as follows:

[0005] A detachable and length-adjustable embedded disc-buckle scaffolding wall connection part comprises an embedded bolt sleeve, a front screw rod, an adjustable connecting sleeve and a rear screw rod; the front screw rod comprises a front threaded section for connecting with the embedded bolt sleeve and a rear threaded section for connecting with the adjustable connecting sleeve, a shoulder baffle is arranged between the front threaded section and the rear threaded section, two ends of the adjustable connecting sleeve are provided with internal threads, which are respectively used to connect with the front screw rod and the rear screw rod, an observation window is arranged in the middle of the adjustable connecting sleeve, the front section of the rear screw rod is a threaded rod section for connecting with the adjustable connecting sleeve, and a disc-buckle latch is arranged at the tail of the threaded rod section.

[0006] The detachable and length-adjustable embedded disc-buckle scaffolding wall connecting piece has an adjustment hole arranged along the diameter direction on the rear thread section of the front screw rod.

[0007] The detachable and length-adjustable embedded disc-lock scaffolding wall connection piece, the front screw rod, the adjustable connecting sleeve and the rear screw rod are connected by bolts and support the spacing distance between the disc-lock frame upright pole and the concrete structure.

[0008] The above-mentioned detachable and length-adjustable embedded disc-shaped scaffolding wall connection member proposed in the utility model has the following advantages compared with the traditional wall connection member:

[0009] 1. The utility model is composed of a pre-embedded bolt sleeve, a front screw with a bolt, an adjustable connecting sleeve, and a rear screw with a buckle latch. The pre-embedded bolt sleeve can reduce the workload of repairs, and the rest of the wall connection parts except the pre-embedded parts can be recycled and reused.

[0010] 2. The length of the wall connecting member in the utility model is adjustable. The extension length of the front and rear screws is controlled by an adjustable connecting sleeve to control the length of the entire wall connecting member, thereby being able to adapt to different concrete structures and the spacing distances between the buckle frames.

[0011] 3. The rear screw rod is equipped with a national standard buckle pin, which can be directly connected to the connecting plate of the buckle frame upright, making it convenient for construction workers to operate.

[0012] 4. The adjustable connecting sleeve is equipped with an observation hole and a scale on the surface, so that the length of the front and rear screws extending into the sleeve can be visually seen, which is convenient for inspection. BRIEF DESCRIPTION OF THE DRAWINGS
