Description

Technical Field

[0001] The utility model belongs to the field of supporting rods for construction engineering, and in particular relates to an adjustable telescopic post-casting strip supporting rod. Background Art

[0002] In building construction, especially when building basements or underground garages, in order to ensure the safety and stability of the structure, it is usually necessary to leave post-cast strips during the concrete pouring process. The purpose of setting post-cast strips is to alleviate the adverse effects of factors such as concrete shrinkage and temperature changes on the structure. In order to support these post-cast strips and ensure their position and shape, temporary support structures are usually required. There are two main traditional post-cast strip support methods: one is to use steel pipe scaffolding as support, and the other is to use columns made of round steel or other materials for support. Both methods have their advantages and disadvantages:

[0003] (1) Steel pipe scaffolding support: Although it is highly reliable, it requires a large number of steel pipes and connectors, which not only increases costs but also reduces material turnover and utilization. In addition, the erection and dismantling of steel pipe scaffolding is complicated, consumes a lot of manpower and time, and may hinder the passage inside the basement or underground garage, affecting construction efficiency and safety.

[0004] (2) Column support made of round steel or other materials: The length of the support material needs to be customized according to the specific location and structural characteristics of the post-cast strip, which makes it impossible to achieve unified and standardized production, resulting in low material utilization. After the support is set, it is often necessary to pour concrete piers at the bottom to ensure stability, which increases the complexity and cost of construction.

[0005] Therefore, in view of the shortcomings of the existing technology, there is an urgent need for a new type of post-casting strip support method and device, which can not only ensure the stability and reliability of the support, but also improve the turnover rate of materials, simplify the construction process, reduce construction costs, and avoid affecting the passage of the construction site. Summary of the invention

[0006] In order to solve the above problems, the utility model discloses an adjustable telescopic post-casting strip support rod, including an adjustable base and a support rod, wherein the adjustable base is fixedly connected to the support rod by bolts, and the adjustable base includes a first steel plate, a second steel plate, a first hollow cylinder, and a second hollow cylinder, wherein the first hollow cylinder is fixedly connected to the first steel plate, and the second hollow cylinder is fixedly connected to the second steel plate, and a spring is arranged inside the second hollow cylinder, and the spring is fixedly connected to the second steel plate. The utility model can effectively adapt to the post-casting strip support requirements of different layer heights and plate thicknesses through an adjustable structure, improve the utilization rate of materials, simplify the construction process, reduce the construction cost, and improve the safety and efficiency of the construction site at the same time. In addition, the support rod of the present invention can be reused, has good economic benefits and practical value, and is suitable for wide application in engineering construction.

[0007] In order to achieve the above object, the technical solution of the utility model is as follows:

[0008] An adjustable telescopic post-cast strip support rod comprises an adjustable base and a support rod. The adjustable base and the support rod are fixedly connected by bolts. The adjustable base comprises a first steel plate, a second steel plate, a first hollow cylinder, and a second hollow cylinder. The first hollow cylinder is fixedly connected to the first steel plate, the second hollow cylinder is fixedly connected to the second steel plate, a spring is arranged in the second hollow cylinder, and the spring is fixedly connected to the second steel plate.

[0009] As an improvement of the utility model, the first hollow cylinder is welded to the first steel plate, the second hollow cylinder is welded to the second steel plate, and the spring is welded to the second steel plate.

[0010] As an improvement of the present invention, holes with a diameter of 22 mm are provided at the four corners of the first steel plate.

[0011] As an improvement of the present invention, holes with a diameter of 22 mm are provided at the four corners of the second steel plate.

[0013] As an improvement of the present utility model, the support rod comprises a third steel plate and a fourth steel plate, and a third hollow cylinder is fixedly connected between the third steel plate and the fourth steel plate.

[0014] As an improvement of the present utility model, the third hollow cylinder is welded between the third steel plate and the fourth steel plate.

[0015] As an improvement of the present invention, the first steel plate and the fourth steel plate are connected and fixed by bolts.

[0016] The beneficial effects of the utility model are:

Compared with traditional steel pipe scaffolding support or round steel column support, the device of the present invention is easy to install and disassemble, reducing construction time and improving construction efficiency.

[0018] (2) The support rods provided in this application can be reused, which reduces material consumption and labor costs, thereby reducing construction costs and having significant economic benefits. At the same time, the support rods are fixed and connected by bolts, which ensures the stability and reliability of the structure and improves the safety of the construction site.

[0019] (3) Compared with the traditional support method that uses steel pipes or round steel materials, which have poor adaptability and are difficult to reuse, this application promotes the turnover of materials and reduces resource waste through standardized and modular design. At the same time, the design of this application is more compact, effectively avoiding the situation that affects the internal traffic of the construction site, ensuring unobstructed access to the construction site.

If the basement raft is uneven after concrete pouring, the bottom can be padded with steel plates or leveled with mortar.

[0045] Specifically, the working principle of the utility model is as follows:

[0046] The present invention includes two major parts, an adjustable base 1 and a support rod 2, which are fixedly connected by bolts 3. Among them, the adjustable base 1 is composed of a first steel plate 11, a second steel plate 12, a first hollow cylinder 13, and a second hollow cylinder 14, and these parts are connected by welding or bolts 3 to form a stable support base.

The connection between the first steel plate 11 and the fourth steel plate 22 is fixed by bolts 3, which ensures the stability and reliability of the entire support rod 2. When the support height of the post-casting strip needs to be adjusted, the pressure of the spring 15 in the second hollow cylinder 14 can be adjusted to adjust the height of the entire support rod 2. This design allows the support rod 2 to be flexibly adjusted in height within a certain range to accommodate basements with different heights or roofs with different thicknesses.

[0047] The support rod 2 is suitable for supporting the top plate of a basement or a basement, especially in the post-cast zone area. If the surface of the basement raft is uneven, the stability and horizontality of the base can be ensured by laying a steel plate or using mortar for leveling, thereby ensuring the safety and reliability of the entire support system.

[0048] The design of the present invention not only improves the safety and stability of the post-casting strip support, but also greatly improves the utilization rate of materials and the flexibility of construction due to the adjustability of the support rod 2. In addition, the reusability of the support rod 2 also significantly reduces the cost and has good economic benefits.

[0049] In summary, the adjustable telescopic post-cast strip support rod of the present invention effectively solves the problems existing in the traditional post-cast strip support method, such as low material utilization rate and high construction complexity, through its unique structural design and height adjustment mechanism, and provides a safe, economical and efficient post-cast strip support solution.
