[0033] Figure 1 The schematic diagram of the structure of the inclined truss steel structure transfer layer of the present application is shown. Figure 2 The figure shows a three-dimensional structure diagram of a tilted truss steel structure transfer layer structure of the present application. Figure 1-Figure 2 As shown, based on one aspect of the present application, the present application provides an inclined truss steel structure transfer layer structure, comprising:

[0034] The main steel beam 1 is constructed from Q235H steel with specifications of HM244*175*7*11. Q235H steel offers high strength and excellent load-bearing capacity, making it suitable for long-span structures and ensuring their safety and stability. Furthermore, its wide cross-section and superior bending resistance effectively reduce structural deformation and improve overall stability. Furthermore, this material offers a high cost-effectiveness, helping to reduce project costs. Furthermore, H-shaped steel offers excellent seismic resistance, making it suitable for buildings requiring earthquake-resistant design, thereby comprehensively improving the safety and cost-effectiveness of the structure.

[0035] The hoop structure 2 includes four rectangularly distributed first angle irons 201, the lower part of the first angle irons 201 clamps the inclined truss 3 in the vertical direction, and the upper part of the first angle irons 201 clamps the main steel beam 1 in the horizontal direction; the lower end of the first angle iron 201 is connected by two second angle irons 202 in the first direction, and the six angle irons at the lower end are fixed by two high-strength wire rods 203 bolts in the second direction; the upper end of the first angle iron 201 is connected by two second angle irons 202 in the first direction, and the six angle irons at the upper end are fixed by two high-strength wire rods 203 bolts in the second direction; the first angle iron 201 is connected by two third angle irons 204 in the second direction at the connection position of the inclined truss 3 and the main steel beam 1, and the six angle irons at the connection position are fixed by two high-strength wire rods 203 bolts in the first direction.

[0036] As can be understood by those skilled in the art, the present application uses the hoop structure 2 as the main connecting element between the steel structure transfer layer and the inclined truss, which improves the stability and durability of the connection and improves the construction efficiency. The connection method of the hoop structure does not require welding or complex bolt fixation, and is relatively easy to disassemble and adjust, which is more convenient when replacement, repair or adjustment is required. Once welding is completed, disassembly is more difficult and the structure is easily damaged. The hoop structure is connected by a high-strength wire rod, and through precise pre-tightening force control, a stable connection can be achieved, reducing quality problems such as cracks, deformation, and uneven connection strength that may occur during the welding process.

[0037] Furthermore, in some embodiments, before installing the main steel beam 1 and the hoop structure 2, the fire retardant coating on the contact surface between the main steel beam 1 and the inclined truss 3 needs to be removed. As those skilled in the art will appreciate, rigorous and refined treatment of the fire retardant coating on the contact surface between the main steel beam 1 and the inclined truss 3 reduces installation problems caused by poor contact surfaces.

[0038] Furthermore, some embodiments further include: high-precision steel wedges 4, placed between the main steel beam 1 and the inclined trusses 3, to ensure that the main steel beam 1 is perpendicular to the ground. As will be understood by those skilled in the art, the use of high-precision steel wedges 4 for leveling between the main steel beam 1 and the inclined trusses 3 achieves high-precision vertical positioning of the main steel beam 1, improving the overall stability and aesthetics of the structure.

[0039] Furthermore, in some embodiments, the first angle iron 201, the second angle iron 202, and the third angle iron 204 are made of L-shaped steel with a cross-section of L50*3. The L-shaped steel structure of this specification is lightweight and has a strong load-bearing capacity. It can provide reliable support and has good bending and torsion resistance to ensure the stability of the connection. Secondly, L-shaped steel is easy to process and install, and can be quickly fixed through flexible connection methods to improve construction efficiency. In addition, L503 L-shaped steel has a high cost performance and low material cost, is suitable for large-scale use, and is highly durable, has good corrosion resistance and aging resistance, ensuring the long-term stability and durability of the structure.

[0040] Furthermore, in some embodiments, the high-strength screw 203 utilizes an M12 high-strength screw with a grade of 8.8. This M12 high-strength screw has high tensile and yield strength, ensuring reliable connections under high loads. It also exhibits excellent fatigue resistance, making it suitable for applications subject to long-term, repetitive loads. Through precise preload control, this screw ensures uniform force distribution, enhances connection stability, and reduces the risk of loosening or slippage.

[0041] Furthermore, in some embodiments, the inclined truss steel transfer layer structure includes at least two sets of main steel beams 1 and hoop structures 2, each set of main steel beams 1 and hoop structures 2 being evenly spaced 3 meters apart on the inclined trusses 3. This design ensures uniform stress distribution, reduces local stress concentration, and improves overall stability and safety. The even spacing of 3 meters helps balance the structure's center of gravity, enhances torsional and lateral resistance, and prevents deformation.

[0042] According to another aspect of the present application, the present application provides a method for installing a tilted truss steel structure transfer layer, comprising:

[0043] Components of prefabricated main steel beam 1 and hoop structure 2;

[0044] Splicing and installing the hoop structure 2: distribute the four first angle irons 201 according to the preset length and width rectangle, place the first angle iron 201 at the preset connection position between the inclined truss 3 and the main steel beam 1, connect them in the second direction through two third angle irons 204, and fix the six angle irons at the connection position through two high-strength wire rods 203 bolts in the first direction; place the lower part of the first angle iron 201 on the inclined truss 3, connect the lower end of the first angle iron 201 through two second angle irons 202 in the first direction, and fix the six angle irons at the lower end through two high-strength wire rods 203 bolts in the second direction, and the lower part of the first angle iron 201 clamps the inclined truss 3 in the vertical direction; place the main steel beam 1 on the upper part of the first angle iron 201, connect the upper end of the first angle iron 201 through two second angle irons in the first direction, and fix the six angle irons at the upper end through two high-strength wire rods 203 bolts in the second direction, and the upper part of the first angle iron 201 clamps the main steel beam 1 in the horizontal direction.

[0045] Furthermore, in some embodiments, before splicing and installing the clamp structure 2, the fire retardant coating on the contact surface between the main steel beam 1 and the inclined truss 3 needs to be removed. Specifically, before splicing and installing the clamp structure 2, the contact surface between the main steel beam 1 and the inclined truss 3 is finely processed to remove the fire retardant coating. If necessary, mechanical polishing or chemical cleaning is performed to ensure that the contact surface is clean and free of impurities, thereby enhancing friction and reducing the problem of slippage caused by poor contact surface.

[0046] Furthermore, in some embodiments, before the main steel beam 1 is placed on top of the first angle iron 201, a high-precision steel wedge 4 is placed between the main steel beam 1 and the inclined truss 3 to ensure that the main steel beam 1 is perpendicular to the ground. This application introduces high-precision steel wedges 4 as a leveling tool between the main steel beam 1 and the inclined truss 3 to ensure that the main steel beam 1 is perpendicular to the ground, achieving high-precision vertical positioning of the main steel beam 1 and reducing the risk of stress concentration and structural damage caused by verticality deviation.

[0047] Furthermore, in some embodiments, the inclined truss steel structure transfer layer structure includes at least two groups of main steel beams 1 and hoop structures 2, and each group of the main steel beams 1 and hoop structures 2 are evenly arranged on the inclined truss 3 at intervals of 3m.

[0048] In summary, the inclined truss steel structure transfer layer structure and its installation method of the present application have the following beneficial effects compared with the prior art:

[0049] 1. This application uses a special clamp structure as the primary connection between the main steel beam and the inclined truss. The clamp structure is designed with a high-strength screw connection structure. Through precise preload control, it achieves a stable connection and reduces quality problems caused by welding.

[0050] 2. Before installation, this application shall carry out fine treatment on the contact surface between the main steel beam and the inclined truss, remove the fire retardant coating, and adopt mechanical grinding or chemical cleaning if necessary to ensure that the contact surface between the main steel beam and the inclined truss is clean and free of impurities, enhance friction, and reduce the problem of sliding caused by poor contact surface.

[0051] 3. This application introduces high-precision steel wedges for leveling the main steel beams, ensuring their vertical positioning relative to the ground, reducing stress concentration and structural damage risks caused by verticality deviations, and improving the overall stability and aesthetics of the structure.

[0052] The above describes the preferred embodiments of the present application. It should be understood that the present application is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present application without departing from the scope of the technical solutions of the present application, or modify them into equivalent embodiments with equivalent changes, which does not affect the substantive content of the present application.
