Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit support, and in particular to a steel support reinforcement and anti-detachment structure. Background Technology

[0002] Deep foundation pits refer to excavations with a depth exceeding 5 meters (including 5 meters), or projects with particularly complex geological conditions, surrounding environment, and underground pipelines even if the depth does not exceed 5 meters. Support measures are used to reinforce and protect the sidewalls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. Because steel supports are recyclable and reusable, and possess economic and environmental characteristics, they are widely used in deep foundation pit support.

[0003] In practical use, we have found that because the steel support is a segmented and combined steel pipe, and the steel support is too large and heavy, it is prone to breakage at the connection of the segments and to falling off at both ends, causing injury. Therefore, there is an urgent need for a steel support reinforcement and anti-fall-off structure. Utility Model Content

[0004] In order to improve the structural stability of steel supports, this utility model provides a steel support reinforcement and anti-detachment structure.

[0005] This utility model is achieved through the following technical solution: a steel support reinforcement and anti-detachment structure, including a fixed end anti-detachment device, a steel support reinforcement mechanism, a steel support connection reinforcement device, and a structural connection sleeve;

[0006] The steel support reinforcement mechanism includes at least three straight steel purlins extending along the length of the support steel pipe of the steel support, and each straight steel purlin includes a multi-section steel purlin structure;

[0007] The fixed-end anti-detachment device includes inclined steel purlins that are respectively connected to the ends of the straight steel purlins, and the free ends of the inclined steel purlins have connecting steel purlin parts that are connected and matched with the foundation pit.

[0008] The steel support connection reinforcement device includes multiple connecting rings that fit with the steel support. The main body of the connecting ring has square holes that fit with the straight steel purlins. The inner wall of the main body of the connecting ring is provided with multiple connecting plates. There are locking slots between adjacent connecting plates that fit with the reinforcement plates at the connection of adjacent support steel pipes on the steel support. The connecting plates are provided with positioning bolts that are screwed to the connection of adjacent support steel pipes.

[0009] The structural connecting sleeve includes a hollow sleeve that fits between two adjacent steel purlin sections on a straight steel purlin, and the hollow sleeve is provided with a locking part that is fitted and positioned to engage with the adjacent two steel purlin sections.

[0010] As a further improvement to the technical solution of this utility model, the connecting ring includes two mating semi-ring bodies, and connecting blocks are respectively extended at the mating points of the two semi-ring bodies, and the corresponding connecting blocks are connected by a bolt and nut assembly.

[0011] As a further improvement to the technical solution of this utility model, at least one connecting ring opposite the square hole is provided with a connecting bolt that is positioned and fitted with the straight steel purlin.

[0012] As a further improvement to the technical solution of this utility model, at least one connecting steel purlin is provided with a fixed support that is sleeved with the steel waler of the foundation pit. The fixed support includes a base member in the shape of an L-shaped plate. The vertical side of the base member is connected to the connecting steel purlin, and the horizontal side of the base member is supported and cooperated with the steel waler of the foundation pit. The free end of the base member is provided with a side plate that is limited and cooperated with the steel waler of the foundation pit.

[0013] As a further improvement to the technical solution of this utility model, the inclined steel purlin is arranged obliquely outward relative to the straight steel purlin.

[0014] The steel support reinforcement and anti-detachment structure provided by this utility model has the following advantages compared with the prior art:

[0015] This utility model employs a combination of a steel support reinforcement mechanism and a steel support connection reinforcement device to reinforce the joints of the steel support at each section, making it an integral whole and improving the overall stability of the steel support. It can also be reused. By using a fixed end anti-detachment device connected to the pit wall and a fixed support connected to the steel waler to form a fixed end anti-detachment device for the steel support, the problem of steel support detachment is solved, and the safety of construction is improved.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0029] The specific embodiments of this utility model will be described in detail below.

[0030] like Figure 1-8 As shown, this utility model provides a specific embodiment of a steel support reinforcement and anti-detachment structure, including a fixed end anti-detachment device 1, a steel support reinforcement mechanism 2, a steel support connection reinforcement device 3, and a structural connection sleeve 4;

[0031] The steel support reinforcement mechanism 2 includes four straight steel purlins 201 extending along the length of the support steel pipe 601 of the steel support, and each straight steel purlin 201 includes a multi-section steel purlin structure.

[0032] The fixed end anti-detachment device 1 includes inclined steel purlins 101 respectively connected to the ends of the straight steel purlins 201. The free end of the inclined steel purlins 101 has a connecting steel purlin part 102 that is connected and cooperates with the foundation pit. Specifically, in this embodiment, the connecting steel purlin part 102 is connected to the foundation pit wall 701 by bolts.

[0033] The steel support connection reinforcement device 3 includes multiple connecting rings 307 that fit with the steel support. The main body of the connecting ring 307 has square holes 302 that fit with the straight steel purlin 201 with clearance. The inner wall of the main body of the connecting ring 307 is provided with multiple connecting clamps 303. There are locking slots 305 between adjacent connecting clamps 303 that fit with the reinforcement plates 602 at the connection of adjacent support steel pipes 601 on the steel support. The connecting clamps 303 are provided with positioning bolts 304 that are screwed to the connection of adjacent support steel pipes 601.

[0034] The structural connecting sleeve 4 includes a hollow sleeve 401 that fits between two adjacent steel purlin sections on the straight steel purlin 201. The hollow sleeve 401 has a locking part 402 that engages with the adjacent steel purlin sections for positioning and fitting. For example... Figure 5 As shown, the locking part 402 in this embodiment is a bolt structure, but a pin structure can also be used to achieve the insertion and positioning function.

[0035] like Figure 2 As shown, in this embodiment, the connecting ring 307 corresponds to the connection point of the adjacent supporting steel pipe 601. For ease of installation, the structural connecting sleeve 4 is located between two adjacent connecting rings 307.

[0036] In this embodiment, the structure at the connection of adjacent supporting steel pipes 601 is the same. Figure 2 The end structure of the supporting steel pipe 601 shown has connecting plates that fit together at both ends of the pipe body, and several reinforcing plates 602 between the connecting plates and the pipe body. The reinforcing plates 602 serve as reinforcing ribs and are triangular plate structures.

[0037] like Figure 3 As shown, in order to facilitate the installation of the connecting ring 307, the connecting ring 307 includes two mating semi-ring bodies. The mating parts of the two semi-ring bodies are respectively provided with connecting blocks 301, and the corresponding connecting blocks 301 are connected by bolt and nut assemblies.

[0038] In one example of this utility model, at least one connecting ring 307 opposite to the square hole 302 is provided with a connecting bolt 306 that is positioned and fitted through the straight steel purlin 201. Figure 6 As shown, when the square hole 302 is located at the connecting block 301 of the connecting ring 307, there is no need to install the connecting bolt 306. When the square hole 302 is located at other positions of the connecting ring 307, the connecting bolt 306, which is positioned and mates with the straight steel purlin 201, can be installed on the connecting ring 307. This structure can fix the relative position of the connecting ring 307 and the straight steel purlin 201, and fasten the two together.

[0039] Furthermore, to improve the connection stability between the fixed end anti-detachment device 1 and the foundation pit, at least one connecting steel purlin 102 is provided with a fixed support 5 that fits into the steel waler 702 of the foundation pit. The fixed support 5 includes an L-shaped base member 502. The vertical side of the base member 502 is connected to the connecting steel purlin 102, and the horizontal side of the base member 502 supports and cooperates with the steel waler 702 of the foundation pit. The free end of the base member 502 is provided with a side plate 501 that limits and cooperates with the steel waler 702 of the foundation pit. Figure 8 As shown, in this embodiment, the side plate 501 and the base component 502 are connected by bolts.

[0040] like Figure 2 As shown, in this embodiment, the inclined steel purlin 101 is arranged obliquely outward relative to the straight steel purlin 201.

[0041] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
