Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a steel pipe support and a section steel support conversion node in a retaining structure. Background Art

[0002] In the design of the enclosure structure of a single-story basement in a building, in order to save the enclosure cost, the design scheme of full-floor concrete support is often not adopted, but the enclosure structure form of gravity dam plus steel pipe diagonal brace is adopted. In the single-story basement of a certain project, the original enclosure design adopts the combination of gravity dam + angle brace + diagonal brace. The diagonal brace adopts a diameter of φ609 steel pipe brace. After the strength of the concrete bracket of the bottom plate is increased, the earth under the steel pipe brace is excavated, and the construction specification is 400mm*400mm (cross-section length*width) H-shaped steel brace. After the strength of the concrete bracket of the steel brace reaches 100%, the steel pipe brace is removed. The steel brace is retained until the strength of the basement top plate reaches 80%, and is removed after the fertilizer tank is backfilled. Figure 1 As shown, it is a detailed view of the node where the steel support passes through the wall in the above-mentioned enclosure design, wherein the first end of the steel support 2 is connected to the top beam 6 through the first corbel 41, and the steel support 2 is provided with a water stop steel plate 3 at the position where it passes through the outer wall 5 of the structure.

[0003] However, in the above-mentioned retaining structure design, there are problems such as large amount of steel sections used, many concrete corbels on the basement floor, many concrete corbels and embedded steel plates on the purlins, many hoisting operations, welding operations, high costs, long construction period, low safety, etc. Therefore, a conversion node of steel pipe support and steel section support in the retaining structure which combines the advantages of the two supports is needed. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a conversion node between a steel pipe support and a steel support in a retaining structure, which saves a large amount of steel materials, reduces the production of concrete corbels, simplifies the construction process, reduces hoisting operations, and improves construction safety.

[0005] In order to achieve the above technical effects, the utility model provides a conversion node between a steel pipe support and a steel support in a retaining structure, wherein the retaining structure comprises a basement floor, a structural outer wall arranged on the basement floor, and a support pile arranged on the outer side of the structural outer wall, and the conversion node comprises:

[0006] A steel support arranged obliquely, wherein the first end of the steel support is connected to the top of the support pile, and the second end is used to extend through the outer wall of the structure to a side relatively far away from the support pile and is fixedly connected to a conversion plate;

[0007] The steel pipe support is arranged obliquely, wherein the first end of the steel pipe support is connected to the side of the conversion plate facing away from the steel pipe support, and the second end extends along the axial direction of the steel support and is fixedly connected to the basement floor.

[0008] Preferably, a capping beam is fixedly mounted on the top of the support pile, and a first corbel for connecting the first end of the steel support is fixedly mounted on the side end surface of the capping beam.

[0009] Preferably, a second corbel for connecting the second end of the steel pipe support is fixedly installed on the basement floor.

[0010] Preferably, a water-stop steel plate is provided on the steel support at a position passing through the outer wall of the structure.

[0011] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0012] 1) It effectively solved the technical problem of the need for later removal of the basement steel pipe support through the wall. It not only simplified the construction process, saved steel, concrete, machinery, labor, etc., greatly shortened the construction period, reduced costs, and improved the safety during the construction of the enclosure project, but also improved the quality of the basement exterior wall structure and reduced the risk of leakage in the later period.

[0013] 2) It has wide applicability and is suitable for all designs in which steel pipes are supported through walls in enclosure designs. The front support steel pipes in the "SMW method + front support steel pipe", "cast-in-place piles + front support steel pipe" and "PC method + front support steel pipe" in the "self-stabilizing foundation pit support structure technology" can also be effectively applied.

[0014] 3) By adopting the steel pipe support and steel support conversion node in the enclosure structure of the utility model, even if the original design does not require support conversion construction, the self-waterproof characteristics of the structure can be well guaranteed in the support through-wall node, eliminating the conventional hidden dangers of leakage of the basement outer wall.
