Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a detachable fastener-type steel pipe scaffolding connecting member and a construction method thereof. Background Art

[0002] During the erection of fastener-type steel pipe scaffolds in building construction, the method of embedding steel pipes is to bury a vertical short steel pipe about 25 cm into the beam before concrete pouring, with about 25 cm exposed from the back of the beam. After the concrete pouring is completed, a horizontal long steel pipe is used to connect the vertical pole and the vertical short steel pipe. This is the most commonly used method for connecting wall members at present and can play a role in rigid connection.

[0003] However, the connecting members used in the method of embedding steel pipes have high manufacturing costs and are troublesome to disassemble. For some embedded steel pipe connecting members that cannot be removed with a wrench, most are cut with an open flame, which poses a serious fire hazard. At the same time, the cut surfaces may be uneven, and the steel pipes at the cut parts are prone to rusting later and causing water seepage and other problems, affecting subsequent construction. Summary of the Invention

[0004] In order to solve the above technical problems, the inventors have obtained the technical solution of the present invention through practice and summary. The present invention discloses a detachable fastener-type steel pipe scaffolding connecting member, which is installed in a building structure and includes a cubic formwork. The cubic formwork has a hollow structure and an open upper end, and a fixing member is connected inside it. The length of the fixing member is greater than the height of the cubic formwork. A vertical straight pipe is sleeved outside the fixing member. First modules are provided on both sides of the vertical straight pipe. A second module is provided on the side of the first module opposite to the vertical straight pipe. The second module and the first module are spliced and filled between the vertical straight pipe and the cubic formwork to fix the vertical straight pipe.

[0005] Further preferably, the second module includes a base arranged in a trapezoidal structure and a protrusion connected to the top of the base.

[0006] Further preferably, through holes are formed in the first module, and the protrusions are correspondingly matched with the through holes when the first module and the second module are in the closed mold state.

[0007] Further preferably, the height of the protrusion is greater than the length of the through hole.

[0008] Further preferably, a handle is provided on the fixing member.

[0009] Further preferably, both the cubic formwork and the fixing member are made of rubber materials.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment 1

[0028] As Figures 1-4 shown, a detachable fastener-type steel pipe scaffolding connecting wall member is composed of a cube mold 11, a fixing member 2, a vertical straight pipe 3, a first module 4 and a second module 5. A hole matching the cube mold 11 is opened in the building structure 1. During installation, the cube mold 11 with the fixing member 2 is pre-buried in the hole in advance, which can effectively solve the problem that the pre-buried steel pipe cannot be recycled, and ensure the construction safety of the erection of the fastener-type steel pipe scaffolding while being convenient and fast in operation and installation.

[0029] Among them, the cube mold 11 is provided with a hollow structure, a fixing member 2 is provided at the center of its inner bottom, and the length of the fixing member 2 is greater than the height of the cube mold 11. A handle is provided on the fixing member 2. At the same time, both the cube mold 11 and the fixing member 2 are made of rubber materials; the vertical straight pipe 3 matches the size of the fixing member 2. The first module 4 is arranged on both sides of the vertical straight pipe 3, and the second module 5 is arranged on the side of the first module 4 opposite to the vertical straight pipe 3. The vertical straight pipe 3 is sleeved outside the fixing member 2, and then fixed by the first module 4 and the second module 5.

[0030] The second module 5 is composed of a base 51 and a protrusion 52. The base 51 is provided with a right trapezoidal structure, and the protrusion 52 is fixedly connected to the top of the base 51; at the same time, a through hole is opened on the first module 4. When the first module 4 and the second module 5 are in the closed mold state, the protrusion 52 corresponds and cooperates with the through hole. The second module 5 and the first module 4 are spliced and filled between the vertical straight pipe 3 and the cube mold 11 to fix the vertical straight pipe 3 and the fixing member 2 in the cube mold 11, improving the stability of the overall structure.

[0031] And, the height of the protrusion 52 is greater than the length of the through hole. As the first module 4 and the second module 5 are spliced, the protrusion 52 penetrates through the first module 4 and extends outward by a part.
