Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a trestle for prestressed floor construction. Background Technology

[0002] With the widespread application of prestressed concrete flooring technology in industrial buildings, the precise placement and fixing of prestressing tendons has become a key factor affecting construction quality and structural performance. Prestressing tendons are steel strands, which must first pass through corrugated pipes to isolate them from the concrete. In current construction, stirrup structures are commonly used and are mostly made of metal materials, supported by manual binding. However, in situations with high electrical shielding requirements, such as high-voltage test halls, the large number of conventional stirrups makes it difficult to achieve reliable grounding. Utility Model Content

[0003] The purpose of this utility model is to provide a prestressed concrete slab construction support frame that uses an integrally molded plastic support frame, which provides excellent insulation and prevents conduction through the support frame, thus eliminating the need for separate grounding of the support frame. At the same time, it can separate the upper and lower corrugated pipes, allowing each of the upper and lower corrugated pipes to be grounded independently, ensuring the grounding effect.

[0004] This utility model is achieved through the following measures:

[0005] A prestressed concrete slab construction trestle, characterized in that it includes a base and a support frame disposed on the base;

[0006] The support frame includes a lower U-shaped support plate, and upper U-shaped support plates are symmetrically arranged on the top of the two side plates of the lower U-shaped support plate;

[0007] The lower U-shaped support plate is provided with a lower layer of transverse corrugated pipe, and the upper U-shaped support plates on both sides are provided with an upper layer of longitudinal corrugated pipe.

[0008] The support frame includes an annular frame, with L-shaped support legs at the four corners of the annular frame, and protrusions at the bottom of the lower U-shaped support plate, the protrusions being disposed in the annular frame.

[0009] The specific features of this utility model also include:

[0010] The upper U-shaped support plates on both sides and the upper longitudinal corrugated pipe placed inside the upper U-shaped support plates are equipped with binding and limiting steel wires.

[0011] The supporting surface of the upper U-shaped support plate is higher than that of the lower transverse corrugated pipe, thereby ensuring that the upper longitudinal corrugated pipe is higher than the lower transverse corrugated pipe after being supported.

[0012] The support frame is made of insulating material and is integrally formed.

[0013] During construction, the base is placed on the ground, the support frame is placed in the annular frame of the base, the lower transverse corrugated pipe is placed in the lower U-shaped support plate, the upper longitudinal corrugated pipe is placed on the upper U-shaped support plates on both sides, and finally the upper longitudinal corrugated pipe is tied to the upper U-shaped support plate with binding and limiting steel wire.

[0014] The beneficial effects of this utility model are as follows: by adopting an integrally molded plastic support frame, it can provide a good insulation structure and will not conduct through the trestle, thus eliminating the need for separate grounding treatment of the trestle. At the same time, it can separate the upper and lower corrugated pipes, so that the upper and lower corrugated pipes can be grounded separately, ensuring the grounding effect.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] See Figure 1-4 A type of trestle for prestressed concrete construction, comprising a base and a support frame mounted on the base;

[0022] The support frame includes a lower U-shaped support plate 3, and upper U-shaped support plates 5 are symmetrically arranged on the top of the side plates on both sides of the lower U-shaped support plate 3;

[0023] The lower U-shaped support plate 3 is provided with a lower transverse corrugated pipe 8, and the upper U-shaped support plates 5 on both sides are provided with an upper longitudinal corrugated pipe 7.

[0024] The support frame includes an annular frame 1, with L-shaped support legs 2 at the four corners of the annular frame 1, and protrusions 6 at the bottom of the lower U-shaped support plate 3, which are located in the annular frame 1.

[0025] The upper U-shaped support plates 5 on both sides and the upper longitudinal corrugated pipe 7 placed inside the upper U-shaped support plates 5 are equipped with binding and limiting steel wires.

[0026] The supporting surface of the upper U-shaped support plate 5 is higher than that of the lower transverse corrugated pipe 8, thus ensuring that the upper longitudinal corrugated pipe 7 is higher than the lower transverse corrugated pipe 8 after being supported.

[0027] The support frame is made of insulating material and is molded in one piece.

[0028] During construction, the base is placed on the ground, the support frame is placed in the annular frame 1 of the base, the lower transverse corrugated pipe 8 is placed in the lower U-shaped support plate 3, the upper longitudinal corrugated pipe 7 is placed on the upper U-shaped support plates 5 on both sides, and finally the upper longitudinal corrugated pipe 7 is tied to the upper U-shaped support plate 5 with binding and limiting steel wire.
