Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a ground-free middle support structure for a beam bottom. Background Art

[0002] During the construction of reinforced concrete beams, in order to ensure stability and safety during the construction process, the middle bottom of the current beam bottom is usually supported by a ground-type steel pipe to construct a structural system for supporting the bottom of the reinforced concrete beam.

[0003] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0004] As supporting columns, floor-mounted steel pipes are the core components of the support system. Their length needs to be designed according to the height of the beam. In addition, since floor-mounted steel pipes need to be directly erected on the ground, the construction and disassembly of the support system are very complicated. At the same time, in order to prevent the steel pipes from sinking or tilting under load, a base is usually required to fix the steel pipes on the ground, which inevitably involves more components and connections, resulting in low construction efficiency.

[0005] Therefore, the above technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the utility model proposes a ground-free intermediate support structure for the bottom of the beam, which solves the problem that the current intermediate support for the bottom of reinforced concrete beams is generally a ground-type steel pipe, which has very cumbersome procedures during assembly and disassembly and low construction efficiency.

[0007] In order to solve the above technical problems, the basic technical solutions proposed by the present invention are as follows:

[0008] A non-ground-proof middle support structure for the bottom of a beam, comprising a non-ground-proof support component arranged in the middle of the bottom of the beam,

[0009] The ground-proof support structure includes a first cross brace assembly that is erected off the ground and arranged below the beam perpendicular to the length direction of the beam, and two short steel pipes that are vertically inserted into the top of the first cross brace assembly. The bottoms of the outer walls of the two short steel pipes are coaxially provided with a first retaining ring for limiting and supporting them.

[0010] Preferably, a stand is also included for the installation of the non-ground support member. The stand includes two long steel pipes, both of which are vertically fixed to the ground through a base. The two long steel pipes are symmetrically distributed and respectively arranged on both sides of the beam. A second cross brace assembly for supporting the bottom of the beam is installed in parallel between the two long steel pipes and above the first cross brace assembly. The stand provides structural support for the installation of the non-ground support member. The two long steel pipes are respectively arranged on both sides of the beam, respectively used to provide structural support for both sides of the beam, and at the same time provide structural support for the assembly of the first cross brace assembly and the second cross brace assembly. It should be noted that two tray structures distributed upper and lower are coaxially pre-welded on the outer walls of the two long steel pipes to provide structural support for the second cross brace assembly and the first cross brace assembly respectively.

[0011] Preferably, a plurality of parallel and evenly spaced wooden planks are placed between the second cross-bracing assembly and the bottom of the beam, with the planks distributed along the length of the beam. The planks placed between the second cross-bracing assembly and the bottom of the beam provide support and reinforcement at the bottom of the beam, forming a stable support structure that ensures the beam does not deform or shift during concrete pouring or other loads. The placement of the planks further enhances the beam's load-bearing capacity and stability.

[0012] Preferably, the first and second cross brace assemblies have the same structure, comprising two symmetrically spaced channel steels clamped and mounted between two long steel tubes via a plurality of tension bolts. Using double channel steels with tension bolts as the cross brace in the support system significantly improves the beam's bearing capacity and rigidity, while simplifying construction and facilitating assembly and disassembly.

[0013] Preferably, the tops of the long steel pipe and the short steel pipe are both mounted with support frames through a necking structure, wherein the support frames are auxiliary support structures to expand the support area and further ensure the support effect.

[0014] Preferably, the support frame comprises a connecting tube coaxially snap-fitted with the necking structure and a support plate welded to the top of the connecting tube. A second retaining ring is coaxially provided on the outer wall of the connecting tube for its installation and positioning. The second retaining ring is used to connect to the position limiter inserted into the necking structure and cooperate with the support plate to achieve support. It should be noted that the support plate has a concave cross-section, and the spacing between its two side edges allows for the second cross-bracing assembly to be snap-fitted.

[0015] The beneficial effects of the utility model are:

[0016] The technical solution of the utility model is to provide a non-ground support component.

[0017] 1. It can be installed by assembling on the ground and then hoisting, which simplifies the process and makes assembly and disassembly more convenient. At the same time, the construction is fast, labor is saved, and it is beneficial to the progress of the project.

[0018] 2. Due to its non-ground feature, compared with floor-standing steel pipes, it can more effectively utilize space, reduce ground occupation, and reduce the impact on construction site layout and traffic. In addition, the non-ground support system has more advantages in certain special environments, such as underwater construction or construction scenes that need to cross obstacles.
