Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a wall-connecting structure for high-rise external scaffolding, which is suitable for use as a wall-connecting structure for external scaffolding with a floor height of 4m to 9m. Background Technology

[0002] With the rapid development of the social economy, high-rise factories, warehouses, and other frame structures are constantly emerging, placing higher demands on the stability of external scaffolding construction. According to Article 6.4.2 of the "Safety Technical Specification for Construction Coupler-Type Steel Pipe Scaffolding" (JGJ130-2011), regarding the installation requirements for wall ties: when the height of double-row ground-supported scaffolding is less than or equal to 50m, the maximum spacing of wall ties should be 3 steps and 3 spans, with a coverage area not exceeding 40m². 2 .

[0003] The current standard practice for wall ties is to pre-embed steel pipes (or pre-embed bolts on the beams) during the construction of the floor slab concrete on each floor, which are then used as horizontal wall ties during the construction of the external scaffolding; subsequently, the frame columns are constructed, and these ties are used as support columns during the construction of the external scaffolding. For floors with large spans and high ceilings, the main drawback of this construction method is that before the upper floor beams and slabs are constructed, the number of wall ties on the external scaffolding is too small, the free ends of the external scaffolding are too high, the stability of the scaffolding is insufficient, and there is a safety hazard of overall or partial overturning, which fails to meet the requirements of the specifications.

[0004] Based on this, this application provides a wall-connecting structure for high-rise external scaffolding with high structural stability and reliable connection to solve the above problems. Utility Model Content

[0005] This utility model aims to solve the technical problems existing in the prior art. Therefore, this utility model provides a wall-connecting structure for high-rise external scaffolding with high structural stability and reliable connections.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A wall-connected structure for high-rise external scaffolding is provided, comprising: first embedded parts, second embedded parts, first longitudinal horizontal members, transverse small horizontal members, large diagonal members, small diagonal members, and second longitudinal horizontal members. Multiple first embedded parts are embedded in the edge structural beams at three-span intervals of the external scaffolding, and the first embedded parts are aligned with the inner and outer uprights of the external scaffolding. Multiple second embedded parts are positioned opposite each other inside the first embedded parts and embedded in the floor slab structural beams. The first longitudinal horizontal members are connected to the multiple second embedded parts via fasteners. Multiple parallel transverse small horizontal members are connected to the first longitudinal horizontal members, the first embedded parts, and the inner and outer uprights of the external scaffolding via fasteners. Each transverse small horizontal member has a large diagonal member above it, and the two ends of the large diagonal member are connected to the first longitudinal horizontal member and the inner and outer uprights of the external scaffolding via fasteners. Each large diagonal member has a small diagonal member, and the two ends of the small diagonal member are connected to the large diagonal member and the transverse small horizontal member via fasteners. The second longitudinal horizontal member connects all the large diagonal members.

[0008] In some alternative implementations, the second embedded part is 1.2 meters away from the edge of the structure.

[0009] In some optional embodiments, the embedding depth of the first and second embedded parts is not less than 250mm, and the exposed length is 250mm to 300mm.

[0010] In some alternative implementations, the end of the large diagonal brace that is away from the connection with the first longitudinal horizontal brace is connected to the inner and outer uprights of the third step and above on the external scaffolding of that floor.

[0011] In some alternative embodiments, both the small diagonal bar and the second longitudinal horizontal bar are connected to the lower third of the large diagonal bar.

[0012] In some alternative implementations, the small diagonal brace is also connected to the inner upright of the external scaffolding via a fastener.

[0013] In some optional embodiments, the first and second embedded parts have the same structure, including a threaded sleeve, a plug, a steel pipe and a heat shrinkable sleeve. The threaded sleeve is embedded in the structural beam, the plug is welded to the bottom of the threaded sleeve, the outer diameter of the steel pipe is lower than the outer diameter of the threaded sleeve, and a shrinkable opening is provided at its bottom. The shrinkable opening is screwed to the threaded sleeve, and the heat shrinkable sleeve is sleeved between the threaded sleeve and the steel pipe.

[0014] In some optional embodiments, the plug is located inside the threaded sleeve and is provided with a connecting post with a threaded hole. The outer diameter of the connecting post is smaller than the inner diameter of the constricted tube opening of the steel pipe. A connecting ring is welded inside the top opening of the steel pipe. A reinforcing bolt passes through the connecting ring and is threaded to the connecting post of the plug. The threading direction of the reinforcing bolt and the connecting post is opposite to the threading direction of the steel pipe and the threaded sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the first embedded part to locate the connection point with the external scaffolding, and uses the first longitudinal large horizontal bar, the transverse small horizontal bar, the large diagonal bar, the small diagonal bar and the second longitudinal large horizontal bar to form a stable triangular structure that connects the embedded part of the construction layer with the inner and outer uprights of the external scaffolding, thereby avoiding the phenomenon of the free end of the scaffolding being too high during the construction process and achieving the effect of safe production.

[0017] 2. The first and second embedded parts are embedded in the edge structural beam and the floor structural beam respectively, which solves the problem that the floor is thin and the embedded parts may cause cracking, water leakage or insufficient anchorage length. At the same time, the first embedded part can play a positioning role in the connection between the horizontal small horizontal bar and the inner and outer uprights of the external scaffold.

[0018] 3. The designed embedded parts enable the rapid removal and reuse of exposed parts, solving the problem of needing to cut the exposed parts of traditional embedded steel pipes after construction, effectively improving work efficiency and reducing construction costs.

[0030] Example 1

[0031] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides a wall-connecting structure for a high-rise external scaffold, including a first embedded part 1, a second embedded part 2, a first longitudinal main horizontal bar 3, a transverse secondary horizontal bar 4, a large diagonal bar 5, a small diagonal bar 6, and a second longitudinal main horizontal bar 7, wherein:

[0032] Multiple first embedded parts 1 are embedded in the edge structural beams according to the three-span spacing of the outer scaffold 10. The first embedded parts 1 are aligned with the inner and outer uprights of the outer scaffold 10. They can be used to position the installation of the horizontal small horizontal bar 4, ensuring that the horizontal small horizontal bar 4 is smoothly connected to the inner and outer uprights of the outer scaffold 10. At the same time, they can also support the middle part of the horizontal small horizontal bar 4 to prevent instability and deformation caused by the force on the horizontal small horizontal bar.

[0033] Multiple second embedded parts 2 are positioned opposite each other inside the first embedded part 1 and are embedded within the structural beam of the floor slab. Because the floor slab is relatively thin, embedding the second embedded parts may cause cracking, water leakage, or insufficient anchorage length. Therefore, in this embodiment, the second embedded parts are embedded within the structural beam of the floor slab to solve this problem. Preferably, in this embodiment, the second embedded part 2 is 1.2 meters from the edge of the structure.

[0034] Preferably, in this embodiment, the embedding depth of the first embedded part 1 and the second embedded part 2 is not less than 250mm, and the exposed length is 250mm to 300mm.

[0035] The first longitudinal horizontal bar 3 is connected to multiple second embedded parts 2 via cross-shaped fasteners. In this embodiment, the first longitudinal horizontal bar can specifically be a 6m long steel pipe, with the steel pipes connected by butt-joint fasteners.

[0036] Multiple parallel horizontal bars 4 are connected to the first longitudinal horizontal bar 3, the first embedded part 1, and the inner and outer uprights of the external scaffold 10 via cross couplers. That is, in this embodiment, one horizontal bar is set every three spans relative to the external scaffold and is aligned and connected with the inner and outer uprights of the external scaffold.

[0037] Above each horizontal bar 4 is a large diagonal bar 5. Both ends of the large diagonal bar 5 are connected to the first longitudinal horizontal bar 3 and the inner and outer uprights on the scaffolding 10 via swivel couplers. In this embodiment, the end of the large diagonal bar 5 furthest from the first longitudinal horizontal bar 3 is connected to the inner and outer uprights on the third step and above of that floor on the scaffolding 10, so that the wall ties are arranged in a 3-step, 3-span configuration. At the lower 1 / 3 of the large diagonal bar 5, a small diagonal bar 6 is used to support it. Both ends of the small diagonal bar 6 are connected to the large diagonal bar 5 and the horizontal bar 4 via swivel couplers. In other embodiments, the small diagonal bar 6 can also be connected to the inner uprights of the scaffolding 10 via couplers. Finally, at the lower 1 / 3 of the large diagonal bar 5, a second longitudinal horizontal bar 7 is used to securely connect all the large diagonal bars 5, making all the large diagonal bars 5 connected in series into a single unit. This method connects the inner and outer uprights of the external scaffolding to the embedded parts of the construction layer by forming a stable triangular structure with large diagonal braces, small diagonal braces, horizontal small horizontal braces, first longitudinal large horizontal braces, and second longitudinal large horizontal braces. This effectively prevents the steel pipes from becoming unstable and deformed due to excessive length during the stress process. The connection structure is stable and reliable, avoiding the phenomenon of the free end of the scaffolding being too high during construction, thus achieving the effect of safe production.

[0038] The first embedded part 1 and the second embedded part 2 in this embodiment have the same structure and can be steel pipes with a length of 500-550mm.

[0039] Example 2

[0040] The difference from Embodiment 1 lies in the embedded parts; please refer to the appendix of the instruction manual. Figure 3 In this embodiment, the first embedded part 1 and the second embedded part 2 have the same structure, including a threaded sleeve 1.1, a plug 1.2, a steel pipe 1.3 and a heat shrinkable sleeve 1.4. The threaded sleeve 1.1 is embedded in the structural beam, the plug 1.2 is welded to the bottom of the threaded sleeve 1.1, the outer diameter of the steel pipe 1.3 is lower than the outer diameter of the threaded sleeve 1.1, and its bottom is provided with a shrinkage port 1.3.1. The shrinkage port 1.3.1 is screwed to the threaded sleeve 1.1, and the heat shrinkable sleeve 1.4 is sleeved between the threaded sleeve 1.1 and the steel pipe 1.3.

[0041] In practice, the steel pipe is screwed to the threaded sleeve, and then a heat-shrinkable sleeve is fitted between the sleeve and the pipe for heat shrinking treatment. This ensures the sleeve tightly wraps around the pipe, preventing concrete slurry from entering between them during pouring. The assembly formed by the steel pipe and sleeve is then welded to the main reinforcement of the structural beam, completing the concrete pouring. After the building construction is completed, the external scaffolding and wall ties are removed, and the steel pipe is finally unscrewed from the sleeve. The heat-shrinkable sleeve may be damaged during unscrewing, but the removed pipe can be reused without the need for cutting off embedded parts.

[0042] Example 3

[0043] Based on Example 2, as shown in the appendix Figure 3 As shown, in this embodiment, the plug 1.2 is further provided with a connecting post 1.2.1 with a threaded hole inside the threaded sleeve. The outer diameter of the connecting post 1.2.1 is smaller than the inner diameter of the constricted end 1.3.1 of the steel pipe. A connecting ring 1.3.2 is welded inside the top opening of the steel pipe 1.3. A reinforcing bolt 1.5 passes through the connecting ring 1.3.2 and is screwed to the connecting post 1.2.1 of the plug. The screwing direction of the reinforcing bolt 1.5 and the connecting post 1.2.1 is opposite to the screwing direction of the steel pipe 1.3 and the threaded sleeve 1.1. This embodiment further utilizes the reinforcing bolt to ensure the connection strength between the steel pipe and the threaded sleeve. At the same time, the reinforcing bolt is installed with a reverse thread relative to the steel pipe, which can effectively prevent the steel pipe from loosening.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
