Description

Technical Field:

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a formwork support system for a construction environment with limited space. Background Art:

[0002] In engineering production and construction, concrete pouring is inevitably involved. For example, a concrete retaining wall, as a key link in construction, requires precise and stable formwork support to ensure the quality and safety of the structure. However, in narrow or space-constrained environments, traditional formwork support systems are often difficult to deploy or have poor effects, resulting in reduced construction efficiency and difficult-to-guarantee construction quality. In addition, the formwork may expand or deform due to the pressure of concrete pouring during construction, affecting the accuracy of the final structure.

[0003] Existing formwork support systems usually include an external support structure, such as traditional scaffolding support, which may not be applicable or difficult to install in narrow spaces. This may lead to the need to demolish some existing structures to provide sufficient space, or the support system itself will occupy a large construction area, restricting the movement range of construction vehicles and personnel. In addition, it may not provide sufficient adjustment capabilities to adapt to different construction conditions, or may not effectively prevent the deformation and displacement of the formwork during construction. Summary of the Utility Model:

[0004] The purpose of the utility model is to provide a tension formwork support system applicable to a narrow construction environment. The system can achieve stable fixation of the formwork through simple operations, and at the same time has an adjustment function to adapt to different construction requirements, and effectively fixes the formwork to prevent the deformation and expansion of the formwork during construction.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a tensioning formwork support system applicable to space - limited areas. The support system includes a plurality of support units. A single support unit includes an upper tensioning support system and a lower tensioning support system. The lower tensioning support system includes a tensioning rod and nuts. The tensioning rod is horizontally arranged and passes through the lower parts of two symmetrically - arranged templates on the left and right. Nuts are sleeved at both ends of the tensioning rod, and the lower ends of the two templates are fixed by the nuts and the tensioning rod. The upper tensioning support system includes support systems on the left and right sides. The support systems on the left and right sides are symmetrically arranged. Each side support system includes two steel ropes, two steel pipes, a threaded sleeve, a base and a steel bar. One end of the first steel rope passes through a hole position on the top of one side template and is fixed on the top of the other side template, and the other end is fixedly connected to one end of a steel pipe. One end of the second steel rope is fixedly connected to the other steel pipe, and the other end is connected to the base. The two steel pipes fixedly connected to the steel ropes are respectively installed on both sides of the threaded sleeve in opposite rotation directions. The base is fixed on the structural foundation through the steel bar. By rotating the threaded sleeve to tighten the two steel ropes, the upper parts of the two templates are fixed through tensioning on the left and right sides.

[0007] The multiple support units are equally spaced.

[0008] One end of the steel pipe is provided with an external thread matching the internal thread in the threaded sleeve. The threaded sides of the two steel pipes fixedly connected to the steel ropes are respectively installed on both sides of the threaded sleeve in opposite rotation directions.

[0009] The base is provided with a through - hole matching the diameter of the steel bar.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model is particularly suitable for construction environments in narrow positions, mainly used in areas where the formwork of structures does not have a large formwork support construction area. It improves the existing formwork support components for casting. Through the reverse tensioning of steel ropes to adapt to formwork support and fixation under some limited - space conditions, it can effectively improve construction efficiency and the stability of the formwork, ensuring construction quality and safety.

[0012] The utility model has an adjustment function to adapt to different construction requirements and effectively fixes the formwork, preventing the deformation and expansion of the formwork during construction. Description of the drawings:

[0018] See Figure 1 - Figure 2 , the present invention provides a tie formwork support system suitable for space - limited areas. The support system includes a plurality of support units, and the plurality of support units are equidistantly distributed. A single support unit includes an upper tie support system and a lower tie support system. The lower tie support system includes a tie rod 4 and nuts. The tie rod 4 is horizontally arranged and passes through the lower parts of two symmetrically arranged formworks 1 on the left and right. Nuts are sleeved on both ends of the tie rod 4, and the lower ends of the two formworks 1 are fixed by the nuts and the tie rod 4.

The support system fixes both ends of the steel wire ropes 2 on the opposite - side formwork 1 and the structural foundation on both sides of the structural formwork 1. Through the left - and right - hand side tie - in, the upper parts of the two formworks 1 are fixed, preventing the formworks 1 from deforming and expanding during the construction process. The lower tie support system cooperates with the upper tie support system to enhance the overall stability and safety of the formwork 1 and ensure the construction efficiency.

Then fix the base 6 on the structural foundation with a steel bar 7. Rotate the threaded sleeve 3 to adjust the tightness of the two steel ropes 2 so that the two steel ropes 2 are tightened. After completion, install the other side support system in the same way. Through the tension on both sides, the upper parts of the two formworks 1 are fixed. After the support units of several such tie formwork support systems are installed, finally, concrete is poured. After the concrete has strength, it can be dismantled in reverse order.
