[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] During the construction of building structure projects, steel structure projects need to use temporary supports for auxiliary fixation. During the construction process, existing steel pipe scaffolding is generally used for erection. Since the workers' skills of the temporary scaffolding are uneven, they often have to make repeated corrections, which not only delays the construction period but also poses a safety hazard. In addition, the steel pipe scaffolding itself has limited rigidity and requires strict technical control. The quality and safety risks during the installation and disassembly process are relatively large, time-consuming and labor-intensive. At today's construction sites, a scaffolding with low operating difficulty, high safety and convenient turnover is needed.

[0032] In view of this, the utility model provides a temporary support auxiliary device that can be used in steel structure engineering. Figure 1-4, including: multiple steel pillars 1, each of which has at least three connecting plates on one side, and its base is fixed to the ground by expansion bolts 4; steel beams 2, the upper, middle and lower corresponding parts between two adjacent steel pillars 1 are connected to the steel beams 2 by the connecting plates and fasteners; steel oblique beams 3, every two adjacent steel beams 2 are connected to the steel oblique beams 3 by the connecting plates and fasteners; I-shaped steels 7, the I-shaped steels 7 are welded to the tops of adjacent steel pillars 1.

[0033] In the above embodiment, the steel support 1, the connecting plate and the base can be pre-welded together. When splicing on site, they only need to be fixed to the ground by expansion bolts 4, and the steel cross beams, steel inclined beams and the connecting plates are fixed by fasteners, which reduces the difficulty of operation and can be operated without experienced workers. The rigidity is guaranteed after splicing, and there is no need for repeated rectification, which reduces working hours, improves erection efficiency, and improves safety.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "middle", "lower", etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In one embodiment of the utility model, a height adjustment cylinder 6 is further included, which is welded between the top of the steel support 1 and the I-shaped steel 7, and the height thereof is cut according to the operation requirements. Thus, the operation flexibility of different requirements is improved, and the use in more scenarios is met.

[0036] In another embodiment of the utility model, if the height is insufficient, a top steel sheet 5 may be further included, wherein the top steel sheet 5 is fixed to the top of the steel pillar 1, and the top steel sheet 5 is connected to the steel pillar 1 by four first high-strength bolts.

[0037] In a specific embodiment of the present invention, see the attached Figure 3 and 4 The connecting plate includes a first connecting plate 11 and a second connecting plate 12. The first connecting plate 11 is welded to the upper and bottom of one side of the steel pillar 1, and at least four first bolt holes are reserved thereon, corresponding to the corresponding second bolt holes on the steel beam 2, and connected and fixed by the second high-strength bolts 8; the second connecting plate 12 is welded to the middle of one side of the steel pillar 1, and at least six third bolt holes are reserved thereon, corresponding to the fourth bolt holes on the steel inclined beam 3, and also fixed by the second high-strength bolts 8, and the fastener is the second high-strength bolt 8. Thus, the steel beam and the steel inclined beam are smoothly connected by the second high-strength bolts 8, and the connection strength is improved.

[0039] Advantageously, see Appendix Figure 3 and 4 The connecting plate is a rectangular connecting steel plate, and the corners are cut to form the connecting position. The installation position formed by the cut corners just corresponds to the connecting direction of the steel beam to be connected, which not only has a prompting effect, but also reduces unnecessary materials and reduces weight.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Specifically, when or before erection, first weld the steel support 1, the connecting plate, and the base together in advance. The height of a single set of steel supports can be 4420mm, the length of the steel beam can be 1537mm, the length of the steel inclined beam can be 2325mm, and the supporting steel plate can be 500mm*500mm*10mm with 4 bolt holes reserved. If the height is insufficient, continue to install a set of top steel plates on the upper part, and use 4 second high-strength bolts for connection.

[0044] Then, after the single set of steel pillars are assembled, they are placed on the working ground, and 4 M20 expansion bolts are used to fix the bottom support steel plate to the working surface.

[0045] According to the operation requirements, install the height-adjusting cylinder and weld it to the top steel plate of the steel support. After the installation is completed, use I-shaped steel 400*400*13*21 to weld and connect it to the height-adjusting cylinder.

[0046] In the above steps, the steel pillars are assembled and welded as a whole, and then set up in single or double groups according to the requirements of the fixed structure. Before construction, the steel pillars are placed on the working ground and fixed with M20 expansion bolts. Finally, the height adjustment cylinders are installed according to the height requirements and cut and removed after use.

[0047] The utility model improves construction efficiency and shortens construction period. It improves construction safety and reduces accident risks.
