DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The present application provides an anti-overturning structure of an oblique steel pipe column support to enhance the stability of the steel pipe column support and prevent the steel pipe column support from overturning during construction and causing safety accidents. Specifically, Figure 1 A front view of an anti-overturning structure of an inclined steel pipe column support provided in an embodiment of the utility model includes a main frame and a wall structure. The bottom of the main frame is arranged on a pre-built pedestal 501. The cross-sectional size of the pedestal 501 is generally 8m×7.5m. The wall structure connects the main frame and the pier 502 to enhance the stability between the main frame and the pier 502 and avoid overturning of the main frame. The cross-sectional size of the pier 502 is generally 6.5m×2.4m.

Specifically, the main frame includes a first steel pipe column 101 and a second steel pipe column 102, and the first steel pipe column 101 is vertically arranged in the base 501, the bottom of the second steel pipe column 102 is fixed to the first steel pipe column 101, the top of the second steel pipe column 102 is far away from the top of the first steel pipe column 101, and the maximum distance between the top of the second steel pipe column 102 and the top of the first steel pipe column 101 is 5.5 meters. The main frame also includes a connection system for firmly connecting the first steel pipe column 101 and the second steel pipe column 102. Specifically, the connection system includes a plurality of oblique bracing channel steels 302 and a plurality of transverse bracing channel steels 301, and the transverse bracing channel steels 302 are connected to the first steel pipe column 101. 01 are welded in parallel between the first steel tube column 101 and the second steel tube column 102 in sequence, the two ends of the diagonal brace channel steel 302 are respectively connected to the head end and the tail end of the two adjacent cross brace channel steels 301, and the two adjacent diagonal brace channel steels 302 are connected head to tail to form a scissors brace as a whole, and the contact points of the diagonal brace channel steel 302 and the cross brace channel steel 301 are both on the two opposite inner sides of the first steel tube column 101 and the second steel tube column 102, which can disperse the force of the main frame while firmly connecting the first steel tube column 101 and the second steel tube column 102 to increase the overall bearing capacity of the main frame. It should be noted that since the distances between the head and tail of the first steel tube column 101 and the second steel tube column 102 are not equal, the lengths of the diagonal brace channel steel 302 and the cross brace channel steel 301 in this application are not equal, and need to be determined according to the specific distance between the first steel tube column 101 and the second steel tube column 102.

[0027] A distribution beam 2 is also provided on the top of the two main frames to bear the upper beam section, formwork, construction load, etc. Figure 4 A schematic structural diagram of a distribution beam 2 in an anti-overturning structure of an oblique steel pipe column support provided in an embodiment of the utility model, specifically, the distribution beam 2 includes an upper beam frame 201, a lower beam frame 202 and multiple longitudinal beams 203, the upper beam frame 201 and the lower beam frame 202 are both square frames formed by four cross beams 204 connected end to end, the four corners of the lower beam frame 202 are respectively welded to the tops of the first steel pipe column 101 and the second steel pipe column 102 in the two main frames, in view of the different forces on the upper and lower distribution beams 2, in the utility model, the cross beam 204 in the upper beam frame 201 adopts a channel steel with a cross-section height of 250mm, the cross beam 204 in the lower beam frame 202 adopts a channel steel with a cross-section height of 450mm, and the longitudinal beam 203 adopts a channel steel with a cross-section height of 400mm.

[0028] A plurality of transverse connecting rods 103 are also provided between the two main frames, and the transverse connecting rods 103 can provide transverse support for the two bracket bodies. Specifically, the transverse connecting rods 103 are respectively and parallelly arranged between the two first steel pipe columns 101 and the two second steel pipe columns 102 of the two main frames, and the number of the transverse connecting rods 103 is consistent with the number of the transverse bracing channel steels 301, and are arranged on the same horizontal line with the transverse bracing channel steels 301. Specifically, two transverse bracing channel steels 301 on the same horizontal plane are connected end to end with the two transverse connecting rods 103 to form a square frame, and the four corners of the square frame are respectively arranged on the four steel pipe columns of the two main frames.

[0029] In order to further enhance the stability of the main frame and prevent it from overturning, a wall connection structure is also provided on the main frame to stabilize the connection between the main frame and the bridge pier 502. Specifically, the wall connection structure includes a wall connection member 403, which is a commonly used component on the market and will not be described in detail here. The wall connection member 403 is used in conjunction with C40 concrete (the standard compressive strength of each cube is 40 MPa) to connect the bridge pier 502 and the first steel pipe column 101. Due to the special shape of the main frame, the simple wall connection member 403 may not meet the anti-overturning requirements. Therefore, the wall connection structure also includes a precision-rolled threaded steel bar 401. The precision-rolled threaded steel bar 401 is a kind of steel pipe with a standard compressive strength of 40 MPa per cubic meter. The diameter of steel 401 is 32 mm, and the number of fine-rolled threaded steel bars 401 is 8, and every two of the fine-rolled threaded steel bars 401 form a group. One group is arranged at the top and middle positions of the main frame. One end of the fine-rolled threaded steel bar 401 passes through the bridge pier 502, and the other end passes through the first steel pipe column 101 and is welded to the inner wall of the second steel pipe column 102. At the same time, a thread and a nut 402 matching the thread are arranged at the end of the fine-rolled threaded steel bar 401 passing through the bridge pier 502, which are used to fix the fine-rolled threaded steel bar 401, and a pre-tightening force of 10t is pre-applied to the nut 402, which can provide anti-gravity support for the main frame.

[0030] In order to further stabilize the reliable connection of the main frame on the pedestal 501, it is necessary to apply an embedded part 503 in advance in the pedestal 501 during the construction of the pedestal 501. The bottoms of the first steel pipe column 101 and the second steel pipe column 102 are buried in the embedded part 503, and then covered and fixed with concrete. The embedded part 503 can not only enhance the connectivity between the bracket body and the ground pedestal 501, but also ensure the verticality requirements of the first steel pipe column 101 and the inclination angle of the second oblique steel pipe column. The embedded part 503 is also a commonly used component and fixing method on the market, which will not be elaborated here.

[0031] The anti-overturning structure of an inclined steel pipe column support provided by the embodiment of the utility model not only connects the main frame and the bridge pier 502 with the commonly used wall connecting parts 403, but also connects the main frame and the bridge pier 502 through the precision-rolled threaded steel 401, thereby enhancing the overall stability and avoiding the risk of overturning of the steel pipe column. The embedded parts 503 are pre-arranged on the pedestal 501, so that the bottom of the main frame is buried in the embedded parts 503, which can also play a supporting role for the main frame to a great extent, ensuring that it stands firmly and reducing the risk of tilting or collapse of the main frame. At the same time, the main frame itself also uses multiple connecting rods, cross bracing channel steels 301 and oblique bracing channel steels 302, which can help disperse the gravity exerted by the building on the main frame, and have a limiting effect on the main frame itself, preventing it from deforming and damaging the overall structure after being subjected to force, thereby further increasing the overall bearing capacity and stability.
