Description

Technical Field

[0001] The utility model relates to the field of building connecting wall members. More specifically, the utility model relates to a building connecting wall member that is easy to disassemble without pre-reserving holes. Background Art

[0002] During the construction of the exterior wall in the field of building construction in the engineering industry, steel pipe scaffolds are usually used as operation scaffolds to set up working platforms, which facilitates the installation of side wall steel bars and formworks by operators. After the scaffold body is erected, it needs to be connected to the building structure to prevent the scaffold body from collapsing. The traditional method of connecting the scaffold to the wall is to embed short steel pipes with large sizes in the beam and slab, and then connect them to the scaffold cross bar through fasteners. However, there are the following disadvantages: due to the large size of the embedded steel pipe, when constructing the upper exterior wall later, holes need to be left at the position of the connecting wall member to facilitate the removal of the steel pipe in the later stage. In this way, there is secondary sealing, but secondary sealing is likely to cause subsequent exterior wall leakage, bringing construction quality risks. Content of the Utility Model

[0003] To achieve these and other advantages of the present utility model, a preferred embodiment of the present utility model provides a building connecting wall member that is easy to disassemble without pre-reserving holes, including:

[0006] The upper floor exterior wall, which is located above the lower floor beam and slab and is fixedly connected to the latter;

[0007] A connecting member, which includes an inner sleeve and an outer sleeve. The inner sleeve is linear, the outer sleeve is L-shaped, one end of the inner sleeve is inserted into the outer sleeve, the end of the inner sleeve away from the outer sleeve is inserted into the scaffold horizontal bar, the outer sleeve is sequentially inserted into the upper floor exterior wall and the lower floor beam and slab, and the bent part of the outer sleeve is buried in the upper floor exterior wall.

[0019] The following further detailed description of the present utility model is provided in conjunction with the drawings, so that those skilled in the art can implement it with reference to the text of the specification.

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be applied to other embodiments, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present utility model.

[0021] As Figure 1-2 shown, a preferred embodiment of the present utility model provides a building connecting wall member that is convenient for disassembly without reserved holes, including:

[0022] A scaffolding, which includes multiple scaffolding vertical poles 1 and multiple scaffolding horizontal poles 2, and the two are vertically arranged;

[0023] A lower floor slab and beam 3, which is arranged at an interval from the scaffolding;

[0024] An upper floor outer wall 4, which is located above the lower floor slab and beam 3 and is fixedly connected to the latter;

[0025] A connecting member 5, which includes an inner sleeve 5-1 and an outer sleeve 5-2. The inner sleeve 5-1 is linear, the outer sleeve 5-2 is L-shaped. One end of the inner sleeve 5-1 is inserted into the outer sleeve 5-2, and the end of the inner sleeve away from the outer sleeve is inserted into the scaffolding horizontal pole. The outer sleeve is sequentially inserted into the upper floor outer wall and the lower floor slab and beam, and the bent part of the outer sleeve is buried in the upper floor outer wall. The outer sleeve is a round steel pipe with a diameter not greater than 50 mm.

[0026] In this embodiment, both the outer sleeve and the inner sleeve are round steel pipes with a diameter not greater than 50 mm, and the size is much smaller than the diameter of the short steel pipes used in existing construction. They are directly buried in the upper floor outer wall during the early construction and finally cut off, so that there is no need to reserve holes. The outer sleeve is obtained by bending a round steel pipe.

[0027] In another technical solution, the inner sleeve 5-1 is connected to the scaffolding through a connecting fastener. The scaffolding vertical pole and the scaffolding horizontal pole are connected by a fastener 6, which is convenient for installation and disassembly.

[0028] In another technical solution, the inner sleeve 5-1 is welded inside the outer sleeve 5-2, and the intersecting part of the two forms a weld 5-3, and double-sided welding is adopted, so that the welding is more firm.

[0029] In another technical solution, the top of the scaffolding is located above the lower floor slab and beam and reaches the horizontal height of the upper floor outer wall, so that it is convenient for construction workers to stand on the scaffolding to carry out construction operations on the upper floor outer wall.

[0030] In another technical solution, the length of the weld shall not be less than 5 times the diameter of the inner sleeve 5-1, so as to ensure the connection firmness between the inner sleeve and the outer sleeve.

[0031] In another technical solution, the part of the outer sleeve 5-2 inserted into the lower floor slab and beam is bound and connected with the beam body steel bars of the lower floor slab and beam. Compared with direct insertion, this combination of steel bar binding and insertion can greatly improve the connection firmness between the connecting member and the lower floor slab and beam.

[0032] In another technical solution, a plurality of limiting protrusions are arranged at intervals on the outer surface of the part of the outer sleeve 5-2 inserted into the lower floor slab and beam. The limiting protrusions are L-shaped, and one end of each of them is perpendicularly welded to the surface of the outer sleeve 5-2. During the process of tying steel bars, the limiting protrusions can play a further role in limiting and fixing the tied steel bars, and the connection firmness is higher.

[0033] The following provides a construction operation method for a building connecting wall member that is easy to disassemble without pre-reserving holes, including the following steps:

[0034] S1. According to the characteristics of the building structure, select and cut the outer sleeve and the inner sleeve (both are round steel pipes) that meet the on-site installation length. The outer sleeve is obtained by processing the round steel pipe through a 90° bending process.

[0035] S2. Weld the outer sleeve and the inner sleeve using double-sided welding. The weld length shall not be less than 5D (where D is the diameter of the outer sleeve), and a pull-out strength test shall be carried out to ensure the welding is reliable and safe.

[0036] S3. After the steel bars and formwork of the lower floor slab and beam are installed, insert one end of the welded connecting member into the outer beam body of the lower floor and tie it to the beam body steel bars; the other end extends to the outside of the beam body and is connected to the external wall scaffold through fasteners.

[0037] S4. Pour the concrete of the lower floor slab and beam. After the concrete strength of the lower floor slab and beam reaches the requirements, carry out the construction of the upper floor external wall.

[0038] S5. After the overall operation construction content of the external wall is completed, remove the external wall operation scaffold from top to bottom. At the same time, use a small cutting tool to cut off the embedded round steel along the external wall facade and remove the horizontal short steel pipe for recycling.

[0039] Although the implementation solutions of the present invention have been disclosed as above, they are not limited to only the applications listed in the description and the implementation modes. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples described here.
