Description

Technical Field

[0001] The utility model relates to a post-cast belt special-shaped disc buckle top support node. Background Art

[0002] The post-cast strip is a reserved joint in the construction of the entire building structure. It is wide and strip-shaped, so it is called a "strip". After the main structure is completed, the post-cast strip will be filled with concrete to make the "joint" disappear. This design is intended to solve a series of problems in building construction, such as differential settlement, temperature shrinkage and other effects.

[0003] However, when pouring concrete, a mold needs to be laid out for the post-casting strip, so a formwork frame is needed to ensure the stability of the post-casting strip before and during pouring to prevent quality problems caused by structural deformation or displacement. Ensure that the construction of the post-casting strip can proceed smoothly.

[0004] The following problems often occur during the construction of traditional post-casting top support nodes:

[0005] (1) Complex frame support: The closed construction of the post-casting strip requires secondary formwork and overall frame support, which increases the difficulty and complexity of construction. At the same time, due to the particularity of the post-casting strip, the formwork and frame support need to pay special attention to issues such as size, position and fixing method to ensure construction quality and safety.

[0006] (2) Inconvenient material turnover: In areas with limited space such as basements, material turnover is particularly difficult. Especially when the post-casting zone is closed, the tower crane is generally dismantled, vertical transportation becomes more difficult, and the method of erecting the overall frame further increases the difficulty and cost of construction.

[0007] (3) Increased labor costs: Since the post-cast strip support frame requires a special installation and removal process, this increases the demand for skilled labor and thus increases labor costs.

[0008] (4) Limited construction efficiency: The installation and dismantling process of traditional steel pipe support frames is relatively cumbersome, and it is necessary to wait until the concrete reaches a certain strength before proceeding. This, to a certain extent, limits the construction efficiency and prolongs the overall construction period. Utility Model Content

[0009] The utility model solves the shortcomings of the prior art and provides a post-casting belt special-shaped disc buckle top support node which can effectively reduce construction procedures and improve construction efficiency.

[0010] To achieve the above-mentioned purpose, the utility model firstly proposes a post-cast strip special-shaped disc-buckle top support node, including a triangular lattice disc-buckle frame, the triangular lattice disc-buckle frame includes a supporting main pipe and a cantilever frame, the top of the supporting main pipe is reserved with a joint for connecting the top support, the bottom end is connected to the formwork frame through a lower connecting pipe, two supporting main pipes are vertically arranged, and a cantilever frame is fixed on the same side of the two supporting main pipes, the length of the cantilever frame matches the distance from the central axis of the post-cast strip to the outermost side of the formwork frame close to the post-cast strip, the two cantilever frames are arranged in parallel, the two supporting main pipes and the ends of the two cantilever frames away from the supporting main pipes are connected and fixed into a whole through horizontally arranged transverse connecting rods, the end of the cantilever frame away from the supporting main pipe is fixed with a vertically arranged gun head for connecting the top support, and a first disc is fixed outside the supporting main pipe at the node position connected to the transverse connecting rod.

[0011] In this embodiment, the cantilever frame is triangular and includes a horizontally arranged cantilever beam and an obliquely arranged diagonal support tube. One end of the cantilever beam and the diagonal support tube is fixed on the gun head and the other end is fixed on the supporting main tube. The cantilever beam and the diagonal support tube are connected and fixed by a vertical connecting rod.

[0012] In this embodiment, a third buckle is fixed on the outer sleeve of the gun head.

[0013] In this embodiment, a top support is detachably connected to the gun head, and the top of the supporting main pipe is threadedly connected to the top support.

[0014] In this embodiment, a second buckle is fixedly mounted on the outer sleeve of the lower connecting pipe.

[0015] In this embodiment, the formwork frame is a disc-type scaffolding.

[0016] With the above structure, the utility model has the following advantages:

[0017] (1) Enhanced structural stability: By adopting top support nodes, the supporting structure in the post-casting zone area has been significantly strengthened, thereby improving the stability of the overall structure. This enhancement helps prevent deformation, cracking and other problems in the structure during construction or after completion, ensuring the safety of the building.

[0018] (2) Improved construction efficiency: The use of post-casting top support nodes simplifies the construction process and reduces unnecessary construction steps. At the same time, due to the improved structural stability, the construction progress can be accelerated and the construction period can be shortened. This not only reduces construction costs, but also helps to improve the overall benefits of the project.

[0019] (3) Improved quality control: The design of the top support node helps to better control the construction quality of the post-casting zone area. By optimizing the support structure, errors and deviations during construction can be reduced and the tight connection between the post-casting zone and the surrounding structure can be ensured. This helps to improve the overall quality of the building and reduce the cost of subsequent maintenance and reinforcement.

[0020] (4) Wide adaptability: The post-cast strip top support node is suitable for various types of building structures and construction environments. Whether it is a high-rise building, a large commercial complex or a residential project, the top support node design can be flexibly adopted according to the actual situation to meet the specific needs of the project.

[0021] In summary, this device solves the problem of the difficulty of conventional post-casting strip formwork in coping with projects with high construction period, quality and safety requirements, and the erection spacing can be based on the spacing of the formwork frames on both sides, without the need for bottom poles, easy to erect, sufficient space and stable structure. It can reduce the maintenance cost caused by common problems and ensure the stability and safety of the main structure during construction. BRIEF DESCRIPTION OF THE DRAWINGS
