Description

Technical Field

[0001] The present invention relates to the technical field of decoration design. In particular, the present invention relates to a post-mounted support structure and installation method for a steel structure building. Background Art

[0002] Currently, the decoration industry is developing towards industrialized modular installation. With the deepening of the advocacy for green buildings, energy conservation and environmental protection, recycling, as well as residential industrialization and industrialization, prefabricated buildings have been vigorously promoted in recent years.

[0003] In recent years, the steel structure output in China has been increasing continuously, with an average annual growth rate of more than 10%, and it still maintains a rapid growth momentum. Steel structure housing is an important branch of prefabricated buildings. In the process of actively exploring the road of industrialized construction, the steel structure housing construction system has been proposed and has become a pioneer on the road of residential industrialization. Revolutionary changes have occurred in the design, production, construction, and use of a series of new materials in steel structure housing. It is the best structural form to achieve green buildings, an important way to realize the modernization of the residential industry, and a new model for the future development of housing in China.

[0004] With the rise of steel structure buildings, the technology of steel structure interior decoration has been put on the agenda. The current market still uses traditional wet decoration processes, lacking mature prefabricated interior decoration processes and methods. That is, decorative panels are installed wet on the outside of the original steel columns. For example, the Chinese patent utility model patent CN212926812U provides a connection node structure between a fiber-reinforced cement decorative panel and a ground foundation, including a building foundation, embedded parts, a wall, a ground foundation, a steel column, a reinforcement member, a thermal insulation layer, a decorative panel, a fireproof board, and a water shedding board; a steel column is provided on the ground foundation beside the wall, a cement mortar surface layer is built on the ground foundation, the steel columns are evenly distributed along the wall, the bottom of the steel column is poured into the ground foundation and is provided with a reinforcement member to strengthen the connection; the decorative panel is a fiber-reinforced cement exterior wall decorative panel, and the decorative panel is fixed by using finished special hanging parts. One end of the finished special hanging part is hung with the decorative panel, and the other end is fixed on the steel column with screws. A rubber gasket is provided on the contact surface between the finished special hanging part and the steel column. A water shedding board is installed at the bottom of the lowermost decorative panel; one end of the water shedding board is fixed on the steel column together with the bottom rubber gasket, the other end of the water shedding board extends obliquely outward, and the water shedding board is arranged along the entire length of the bottom of the decorative panel.

[0005] However, with the increasing proportion of steel structure buildings year by year, more and more problems have emerged in the interior decoration of steel structure buildings under the wet decoration process, which are detailed as follows:

[0006] 1. Cracks are easily generated in the mortar layer due to thermal expansion and contraction.

[0007] 2. The deformation of the surface layer is inconsistent with that of the steel structure main body, resulting in cracks in the surface layer.

[0008] 3. Using traditional decoration methods is likely to damage the fireproof coating of steel structures;

[0009] 4. Traditional decoration construction takes a long time, has low efficiency, and wet operation is not environmentally friendly.

In addition, the terms "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0038] The following description of at least one exemplary embodiment is merely illustrative and in no way a limitation on the present invention and its application or use.

[0039] Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and systems should be regarded as part of the authorization specification.

[0040] Example 1: As Figures 1 to 4 shown, it is only one of the embodiments of the present invention. A post - type support structure for a steel - structure building includes a support column 3, a hoop member 1 provided on the support column 3, a keel plate 2 connected to the hoop member 1, and a panel 4 provided on the keel plate 2. The number of the hoop members 1 is two. The hoop member 1 is provided with a lug 11, and the lugs 11 of the two hoop members 1 are connected by a connecting bolt 13. The lug 11 is provided with a connecting plate 12 for connecting with the keel plate 2. The keel plate 2 is arranged parallel to the connecting plate 12, and an adhesive 23 for connecting with the panel 4 is provided on the side of the keel plate 2 away from the connecting plate 12.

[0041] In the present invention, the support column 3 is a circular column. The hoop member 1 is arranged on the side surface of the support column 3, the keel plate 2 is installed on the hoop member 1, and finally the panel 4 is installed on the keel plate 2 in a way of using the adhesive 23 without nailing.

[0042] First, it is the structure of the hoop member 1. The support column 3 is a circular column, and the hoop member 1 is a semi - circular hoop. Both ends of the hoop member 1 are provided with lugs 11. The lug 11 is provided with a connecting plate 12 for connecting with the keel plate 2. The two hoop members 1 are connected end to end by two groups of connecting bolts 13. The two semi - circular hoop members 1 form a circular hoop around the outside of the support column 3, and the lugs 11 of the two hoop members 1 both extend perpendicularly to the surface of the support column 3.

[0043] Moreover, the included angle between the connecting plate 12 and the lug 11 is 45°. The connecting plates 12 on the lugs 11 at both ends of one hoop member 1 are perpendicularly arranged. The planes of the four connecting plates 12 on the two hoop members 1 form a rectangular structure. Since the four lugs 11 have the same specifications and the four connecting plates 12 have the same specifications, the planes of the four connecting plates 12 just enclose a square structure.

[0044] Then, it is the structure of the keel plate 2. The keel plate 2 is connected to the connecting plate 12, and the keel plate 2 is arranged parallel to the connecting plate 12. An adhesive 23 for connecting with the panel 4 is provided on the side of the keel plate 2 away from the connecting plate 12.

[0045] The keel plate 2 can be snap - connected to the connecting plate 12 or nailed to the connecting plate 12. For the convenience of the assembled installation of the keel plate 2, generally, the keel plate 2 is snap - connected to the connecting plate 12. The structure is as follows:

[0046] At both ends of the keel plate 2, limiting plates 21 perpendicular to the keel plate 2 are respectively arranged. At least a part of the connecting plate 12 is located between the two limiting plates 21, and an arc-shaped plate 22 extending towards the connecting plate 12 is arranged at one end of the limiting plate 21 far from the keel plate 2.

[0047] The keel plate 2 forms a C-shaped structure. When the keel plate 2 is installed, the opening of the keel plate 2 faces the connecting plate 12 for displacement. The distance between the two limiting plates 21 just allows the connecting plate 12 to pass through. When the connecting plate 12 passes through, it will squeeze the arc-shaped plate 22, causing the limiting plates 21 to bounce open to both sides. Until after the connecting plate 12 passes through the arc-shaped plate 22, under the elastic force of the limiting plates 21, the arc-shaped plate 22 buckles the side of the connecting plate far from the keel plate 2, completing the clamping connection between the keel plate 2 and the connecting plate 12.

[0048] Finally, the panel 4 is installed. An adhesive 23 for connecting with the panel 4 is arranged on the side of the keel plate 2 far from the connecting plate 12. In this way, in a nail-free installation method, the panel 4 is flexibly installed on the keel plate 2, effectively avoiding surface layer cracks.

[0049] In this way, each part of the hoop member 1, the keel plate 2, and the panel 4 is produced separately and assembled and installed, which is convenient for installation, has high efficiency, is green and environmentally friendly with little pollution; the installation of the panel 4 does not require the setting of a mortar layer, which can effectively avoid the generation of cracks, and the risk of falling off is also low.

[0050] It should be noted that a fireproof coating 31 is arranged on the outer side of the support column 3; since the panel 4 is installed on the hoop member 1 and the keel plate 2, the hoop member 1 and the support column 3 are fixed by the friction force after being tightened, without nailing or applying cement on the fireproof coating, and the structure of the fireproof coating 31 will not be damaged. Moreover, the installation processes of the keel plate 2 and the panel 4 do not contact the support column 3, and the fireproof coating 31 will not be damaged either.

[0051] A post-mounted support structure for a steel structure building according to the present invention has a simple structure, is assembled and installed, has high dry construction efficiency, is green and environmentally friendly with little pollution; the setting of a mortar layer is not required, which can effectively avoid the generation of cracks, and the panel of the support column is flexibly connected, effectively avoiding surface layer cracks. The parts are prefabricated with interfaces, and the installation difficulty is low, avoiding the shedding of the fireproof coating during the installation process.

[0052] Example 2, still as Figures 1 to 4As shown, this is only one embodiment of the present invention. Based on Embodiment 1, in a post - type support structure of a steel - structure building of the present invention, a welding member 14 is further provided on the hoop member 1. The welding member 14 includes a welding plate 141 provided on the hoop member 1, an extension plate 142 extending perpendicularly to the welding plate 141, and an end plate 143 provided at one end of the extension plate 142 away from the welding plate 141. Keel plates 2 are provided on both the end plate 143 and the connecting plate 12.

[0053] Here, extension plates 142 are provided at both ends of the welding plate 141, and the included angle between the end plate 143 and the extension plate 142 is 45°; the end plates 143 on the extension plates 142 at both ends of one welding plate 141 are perpendicularly arranged.

[0054] Generally, the end plate 143 on one side of the welding plate 141 and the connecting plate 12 on this side of the welding plate 141 are in the same plane; it is equivalent to setting an end plate 143 in the plane of each connecting plate 12, which is convenient for the keel plates 2 on the connecting plate 12 and the keel plates 2 on the end plate 143 to jointly carry and fix a panel 4, and the installation of the panel 4 is more stable.

[0055] In addition, bolt holes 111 for facilitating the passing of the connecting bolt 13 are provided on the lug 11, and a nut 131 is sleeved on the connecting bolt 13.

[0056] Furthermore, the hoop member 1 is a carbon - steel member with a thickness of 5 mm; actually, it can be understood that the hoop member 1 is obtained by bending a 5 - mm - thick carbon - steel straight plate.

[0057] Embodiment 3, as Figure 5 shown, this is only one embodiment of the present invention. The present invention also provides an installation method for a post - type support structure of a steel - structure building in any of the above - mentioned embodiments. The method includes the following steps:

[0058] S1: Weld and set the welding member on the hoop member;

[0060] S3: Install keel plates on the end plate of the welding member and the connecting plate of the hoop member respectively;

[0061] S4: Install the panel on the keel plates through adhesive.

[0062] The post - support structure and installation method of a steel - structure building according to the present invention are simple in structure, assembled for installation, with high dry - construction efficiency, green and environmentally friendly with little pollution. The setting of a mortar layer is not required, which can effectively avoid the generation of cracks. The panel of the support column is flexibly connected to effectively avoid surface cracks. The prefabricated parts are provided with interfaces, which makes the installation easy and avoids the peeling off of the fire - proof coating during the installation process.
