[0027] Figure 1 This is a schematic structural diagram of the first supporting module of the present invention;

[0028] Figure 2 It is a structural schematic diagram of the second supporting module of the present invention. DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be understood that terms such as “having,” “including,” and “comprising” used herein do not prescribe the existence or addition of one or more other elements or combinations thereof.

[0031] like Figure 1 、 2 As shown, the present invention provides a temporary steel trestle support module, comprising:

[0032] A first support module includes a plurality of steel pipe piles 1 distributed in an array, wherein the spacing between adjacent steel pipe piles 1 in a first direction and a second direction is equal, and the number of steel pipe piles in the first direction is twice the number of steel pipe piles in the second direction; two cross-arranged first support rod groups 2 are provided between adjacent steel pipe piles 1 in the first direction, and adjacent first support rod groups 2 in the first direction and adjacent first support rod groups 2 in the second direction are respectively provided at the upper middle portion and the lower middle portion of the steel pipe piles 1; and a second support rod 3 is provided at the middle portion of adjacent steel pipe piles 1 in the second direction;

[0033] A second support module includes a plurality of steel pipe piles 1 distributed in an array, wherein the spacing between the steel pipe piles 1 in the first direction and the second direction is equal, and the number of steel pipe piles in the first direction is equal to the number of steel pipe piles in the second direction; a third support rod 12 is provided in the middle of adjacent steel pipe piles 1 in the first direction; two cross-arranged fourth support rod groups 11 are provided between adjacent steel pipe piles 1 in the second direction, and the fourth support rod groups 11 adjacent in the first direction and the fourth support rod groups 11 adjacent in the second direction are respectively provided in the upper middle portion and the lower middle portion of the steel pipe piles;

[0034] Wherein, the upper end and the lower end of the steel pipe pile are both provided with a connecting portion, and the first supporting module and the second supporting module are self-connected or connected to each other through the connecting portion.

[0035] In the above technical solution, the present invention provides two standard forms of temporary steel trestle support modules. The splicing flexibility of the temporary steel trestle in the length direction and the width direction is achieved according to the selected number of the first support module and the second support module. The unequal side lengths of the first support module make the spliced joints not all on the same straight line, which provides the steel trestle support structure with higher lateral and bending resistance. The first support module and the second support module are spliced together through the connection part, which can greatly reduce the amount of support rods (in the prior art, in order to ensure the lateral resistance of the support structure, the adjacent steel pipe piles are connected). Two sets of cross support rods are set between the steel pipe piles, and oblique support rods are also set between non-adjacent steel pipe piles. The connection parts set on the first support module and the second support module can play both a connecting role and a supporting role. The unconnected connection parts are fixed to the steel pipe pile 1 by bolts to form a certain angle with the direction of water flow. Different unconnected connection parts are installed at different heights and angles through multiple rows of screw holes on the steel pipe pile 1, forming a disordered blocking structure. The impact force of the water flow is gradually weakened from the outside to the inside, thereby forming a graded anti-water flow impact structure and enhancing the overall water flow impact resistance of the support structure. The structure spliced with two standard support modules can be disassembled and reused, reducing the economic cost of temporary projects.

[0036] like Figure 1 and Figure 2In one technical solution, the connecting portion is movably connected to the steel pipe pile through a plurality of rows of screw holes provided on the steel pipe pile, and includes:

[0037] A first connecting portion 8, which is provided at the end of the steel pipe pile 1 having a free connecting end;

[0038] A second connecting portion 5, which is provided at the end of the steel pipe pile provided with the first support rod group 2 or the fourth support rod group 11;

[0039] Among them, the first connecting part 8 and the second connecting part 5 both include a rotating sleeve 9 sleeved on the steel pipe pile and a connecting plate arranged on the rotating sleeve 9 and extending outward, the rotating sleeve 9 is provided with screw holes, the width of the connecting plate is equal to the arc length between adjacent screw holes in the circumferential direction of the steel pipe pile, and the connecting plate is provided with multiple screw holes; the length of the connecting plate of the second connecting part 5 is equal to two-thirds of the length of the connecting plate of the first connecting part 8, and equal to one-quarter of the distance between adjacent steel pipe piles 1.

[0040] In the above technical solution, each of the upper and lower ends of the steel pipe pile of the first support module and the second support module is provided with a connection part. Different connection parts (first connection part and second connection part) are provided according to whether the end has a free connection end, that is, according to whether the connection part can be removed from the end of the steel pipe pile 1. The first connection part can be removed from the steel pipe pile, and the connection plate extending outward is long, and the connection plate extending outward of the second connection part is short. The number of the first support module and the second support module can be selected according to the length and width of the temporary steel trestle. At the same time, the length of the connection formed by the connection part can also be adjusted. In actual use, a part of the connection part is connected to play a connecting role, and the other part of the connection part is not connected, forming a disordered blocking structure, and the impact force of the water flow is gradually weakened from the outside to the inside. Whether it is a connected connection part or an unconnected connection part, its height on the steel pipe pile 1 is adjustable. Under the preferred structure, the connected connection parts are not completely at the same height, and the unconnected connection parts are not completely at the same height. The first and second connecting parts 8, 5 are respectively provided with screw holes 4 and 7, which are connected by bolts. The width of the connecting plates extending outward from the first and second connecting parts 8, 5 is equal to the arc length of adjacent screw holes in the circumferential direction of the steel pipe pile 1. In other words, when the rotating sleeve 9 is fixed to specific adjacent screw holes, the connecting plates extending outward from the first and second connecting parts 8, 5 are arranged in parallel. The length of the connecting plates of the second connecting part 5 and the first connecting part 8 is set to reduce the amount of calculation required during the design phase.

[0041] like Figure 1 and Figure 2 In one of the technical solutions, a screw hole that can be connected to the mounting seat is reserved at the top of the steel pipe pile 1 to facilitate the subsequent installation of the Bailey frame, etc.

[0042] like Figure 1and Figure 2 As shown, in one of the technical solutions, the first support module includes 4 steel pipe piles in the first direction, and the second support module includes 2 steel pipe piles in the first direction. The first support module is rectangular and the second support module is square, which can meet the use of temporary steel trestles of different lengths and widths.

[0043] The present invention further claims protection for a temporary steel trestle support structure, which is a support structure with a size comparable to that of the bridge deck spliced together by multiple first support modules and second support modules, and the outer edges of the support structure are each provided with a first support module or a second support module.

[0044] In one of the technical solutions, the number of connections in the temporary trestle support structure that are completely on the same straight line does not exceed 10, that is, the same support module is not used 10 times continuously on the same straight line. The irregular distribution of the connections is conducive to improving the bending and lateral resistance of the support structure.

[0045] In one of the technical solutions, except for the first support module and the second support module at the outer edge of the supporting structure, among the outer steel pipe piles of other first support modules and second support modules, at least one of the four connecting parts on two adjacent steel pipe piles in the same direction is connected, that is, at least one connecting part on the two steel pipe piles 1 connected to the first support rod 2 or the second support rod 3 and the two steel pipe piles 1 connected to the third support rod 12 or the fourth support rod 11 plays a connecting role. Under more preferred conditions, the two connecting parts on one diagonal line play a connecting role, and the two connecting parts on the other diagonal line play a role in resisting water flow impact.

[0046] The number of equipment and processing scale described here are used to simplify the description of the present invention. Applications, modifications and variations of the temporary steel trestle support modules and support structures of the present invention will be obvious to those skilled in the art.

[0047] As described above, according to the present invention, the present invention has at least the following beneficial effects:

[0048] First, the temporary steel trestle support module provided by the present invention has two standard support modules. The first support module and the second support module have strong splicing properties and can be spliced in a variety of ways to form the bridge deck shape;

[0049] Secondly, each steel pipe pile of the temporary steel trestle support module provided by the present invention is provided with a connecting portion, which is further divided into a first connecting portion and a second connecting portion of different connecting lengths. The length of the connection formed by the connecting portion is controllable, adapting to temporary steel trestle decks of different lengths and widths;

[0050] Thirdly, the unconnected connection parts on the steel pipe piles of the temporary steel trestle support module provided by the present invention can block the water flow force and improve the safety of the support module;

[0051] Fourthly, the temporary steel trestle support module provided by the present invention uses a smaller number of support rods and does not require the provision of longer diagonal braces to achieve higher lateral and bending resistance.

[0052] Fifth, the temporary steel trestle support module provided by the present invention can be recycled, is economical and environmentally friendly, and is particularly suitable for temporary engineering systems such as temporary steel trestle;

[0053] Sixth, the supporting structure formed by the temporary steel trestle supporting module provided by the present invention has multi-directional stress inside, which improves the overall bearing capacity and stability.

[0054] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
