Description

Technical Field

[0001] The present invention relates to the technical field of decoration design. In particular, the present invention relates to a prefabricated cylindrical surface layer for a steel structure building and an installation method thereof. Background Art

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

[0003] For buildings such as large shopping malls, convention centers, and stadiums, due to their high floors, steel structures are commonly used to replace aluminum alloy profiles as partitions or as the main and cross members for curtain walls. Steel structures have a large elastic modulus, can be made into a large-area decorative effect, and have a low cost. However, steel profiles such as steel I-beams in steel structures are inferior to aluminum alloy profiles in terms of bending degree, corrosion resistance, and decorativeness, which also affects the overall effect of the building. Now, more and more attention is paid to the prefabricated installation of the decoration of steel columns made of aluminum alloy profiles. For example, Chinese Patent Invention Patent CN101285327A relates to an aluminum alloy profile assembly for a new type of decorative steel structure curtain wall column, which is mainly used to decorate steel columns for building space partitions or the main and cross members of curtain walls. It includes a wrapping plate, a backing plate, a pressing strip, and an outer inlay strip. There are two wrapping plates, which are arranged symmetrically left and right. The cross-section of each wrapping plate (1) is similar to an "L" - shaped structure, composed of a side panel and an end panel. There are two backing plates, which are arranged symmetrically left and right. The cross-section of each backing plate is similar to a "7" - shaped structure, composed of a vertical side plate and an inverted hook groove arranged on the outer side of one end of the vertical side plate. There is one pressing strip, which is composed of a pressing strip body, a supporting vertical plate, and a connecting foot plate. There is one outer inlay strip, which is composed of an inlay strip body and a claw. This invention uses an aluminum alloy profile assembly to decorate steel structure curtain wall columns, and the material itself has high strength and is relatively convenient to install.

[0004] However, due to the arc of the cylindrical steel structure column, only the wet decoration process can still be used, lacking a mature prefabricated interior decoration process method. With the increasing proportion of steel structure buildings year by year, more and more problems are exposed in the interior decoration of steel structure buildings under the wet decoration process, as detailed below:

[0005] 1. The mortar layer is prone to cracks due to thermal expansion and contraction;

[0006] 2. The deformation of the surface layer is inconsistent with that of the steel structure main body, resulting in cracks in the surface layer;

[0007] 3. Using traditional decoration methods is likely to damage the steel structure fire protection coating;

[0008] 4. Traditional decoration construction takes a long time, has low efficiency, and wet operation is not environmentally friendly.

[0009] Therefore, to solve the above problems, it is necessary for us to design a reasonable and efficient prefabricated cylindrical surface layer for steel structure buildings. Summary of the Invention

[0039] The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present invention and its application or use.

[0040] For technologies, methods, and systems known to those of ordinary skill in the relevant fields, detailed discussions may not be made, but where appropriate, the technologies, methods, and systems should be regarded as part of the authorization specification.

[0041] Embodiment 1: AsFigures 1 to 5 As shown, it is only one embodiment of the present invention, a prefabricated cylindrical surface layer for a steel structure building, including a support column 3, a first connector 1 arranged on the support column 3, a second connector 2 connected to the first connector 1, and a panel 4 arranged on the second connector 2. The first connector 1 is an angle code piece, and a long slot 13 is arranged on the first connector 1. The second connector 2 includes a first plate 21 for connecting to the first connector 1, a second plate 22 for connecting to the panel 4, and a third plate 23 for connecting the first plate 21 and the second plate 22. A bolt hole 211 and a bolt 212 for inserting into the bolt hole 211 are arranged on the first plate 21. At least a part of the bolt 212 is located in the long slot 13, and an adhesive 221 for connecting to the panel 4 is arranged on the second plate 22.

[0042] In the present invention, the support column 3 is a circular column. The first connector 1 is welded on the side surface of the support column 3, and the second connector 2 is installed on the outside of the first connector 1 through bolts. Finally, the panel 4 is installed on the second connector 2 by means of the adhesive 221 without nailing.

[0043] First, it is the structure of the first connector 1. The first connector 1 is an angle code piece. In fact, the first connector 1 includes a first angle code plate 11 and a second angle code plate 12 perpendicular to the first angle code plate 11. In addition, the number of the first connectors 1 is 4. The 4 first connectors 1 are evenly arranged on the outside of the circular support column 3, symmetrically arranged in pairs. The first angle code plates 11 of the 4 first connectors 1 are all parallel, and similarly, the second angle code plates 12 of the 4 first connectors 1 are also all parallel. The first angle code plate 11 of one first connector 1 and the first angle code plate 11 of the adjacent first connector 1 are in the same plane; so that the first angle code plates 11 and the second angle code plates 12 of the 4 first connectors 1 enclose a square space.

[0044] In addition, the first connector 1 is a carbon steel piece with a thickness of 5 mm; in fact, the first angle code plate 11 and the second angle code plate 12 have the same length, which can be understood as bending a 5-mm-thick carbon steel plate in the middle, and the two bent plates are perpendicular to each other.

[0045] In addition, a long slot 13 is arranged on the first connector 1. Long slots 13 are arranged on both the first angle code plate 11 and the second angle code plate 12. The extending direction of the long slot 13 on the first angle code plate 11 is the same as the extending direction of the first angle code plate 11, and the extending direction of the long slot 13 on the second angle code plate 12 is the same as the extending direction of the second angle code plate 12, that is, 8 groups of long slots 13 are arranged.

[0046] Taking the support column 3 as an example of being vertically arranged, the first connecting member 1 is horizontally arranged, and then the long slot 13 is also horizontally arranged.

[0047] Then there is the second connecting member 2. The second connecting member 2 includes a first plate 21 for connecting with the first connecting member 1, a second plate 22 for connecting with the panel 4, and a third plate 23 for connecting the first plate 21 and the second plate 22. The first plate 21 and the second plate 22 are horizontally arranged, and the first plate 21 and the second plate 22 are respectively located on both sides of the third plate 23, so that the second connecting member 2 forms a Z-shaped structure.

[0048] Here, a bolt hole 211 and a bolt 212 for inserting into the bolt hole 211 are provided on the first plate 21. At least a part of the bolt 212 is located in the long slot 13. That is to say, after the bolt 212 passes through the bolt hole 211 and the long slot 13 in sequence, the first plate 21 is connected to the first connecting member 1, that is, the second connecting member 2 is installed on the first connecting member 1.

[0049] In addition, an adhesive 221 for connecting with the panel 4 is provided on the second plate 22. In this way, in the way of nail-free installation, the panel 4 is flexibly installed on the second connecting member 2, effectively avoiding surface layer cracks.

[0050] In this way, the parts of the first connecting member 1, the second connecting member 2 and the panel 4 are produced separately and installed in an assembled manner, which is convenient for installation, high in efficiency, 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.

[0051] Here, since the long slot 13 is a horizontally arranged long extended slot, the position can be adjusted in the horizontal direction when the second connecting member 2 is installed, which can ensure that the panel 4 is vertically installed. And during the thermal expansion and contraction process of the whole structure, the position of the bolt 212 in the long slot 13 can be appropriately adjusted, so that the whole structure will not easily crack.

[0052] It should be noted that a fireproof coating 31 is provided on the outer side of the support column 3; since the first connecting member 1 is pre-welded, the fireproof coating 31 provided on the outer side of the support column 3 also coats and covers a part of the first connecting member 1 by the way. Then the second connecting member 2 is installed on the outer side of the first connecting member 1, and installation holes, namely the long slot 13 and the bolt hole 211, are reserved on the first connecting member 1 and the second connecting member 2. Therefore, the second connecting member 2 will not damage the fireproof coating during installation; and when the panel 4 is installed on the outer side of the second connecting member 2, the fireproof coating will not be damaged even more.

[0053] The structure of a prefabricated cylindrical surface layer of a steel structure building in the present invention is simple, assembled and installed, with high dry construction efficiency, green environmental protection and little pollution; the setting of a mortar layer is not required, which can effectively avoid the generation of cracks, and the flexible connection between the support column and the panel effectively avoids surface layer cracks. The prefabricated parts are provided with interfaces, which are easy to install and avoid the peeling off of the fireproof coating during the installation process.

[0054] Example 2, still as Figures 1 to 5 shown, which is only one of the embodiments of the present invention. On the basis of Example 1, in a prefabricated cylindrical surface layer of a steel structure building in the present invention, the number of the second connectors 2 is 8; one second connector 2 is installed at each long strip groove 13 to form 8 second plates 22, and each panel 4 is respectively connected and fixed by two second plates 22 and an adhesive 221.

[0055] Of course, the 4 first connectors 1 and 8 second connectors 2 are only a set of connection structures arranged on the outer side of the support column 3, and multiple sets of connection structures can be arranged, which has a better installation stability effect on the panel 4.

[0056] In addition, welding inclined surfaces 14 are provided at one end of the first angle code plate 11 away from the second angle code plate 12 and one end of the second angle code plate 12 away from the first angle code plate 11, which increases the welding area between the first connector 1 and the support column 3 and has better welding stability.

[0057] Furthermore, a keel plate 25 is provided on the second plate 22, and the keel plate 25 is connected to the second plate 22 by self-tapping screws 251; the adhesive 221 is provided on a side of the keel plate 25 away from the first plate 21.

[0058] And, one end of the second plate 22 away from the third plate 23 is provided with a fourth plate 24 extending away from the panel 4; the keel plate 25 is respectively provided with a first limiting plate 252 and a second limiting plate 253, the first limiting plate 252 is connected to a side of the third plate 23 away from the fourth plate 24, and the second limiting plate 253 is connected to a side of the fourth plate 24 away from the third plate 23.

[0059] Finally, a nut 213 is sleeved on the bolt 212.

[0060] Example 3, as Figure 6 shown, which is only one of the embodiments of the present invention. The present invention also provides an installation method for a prefabricated cylindrical surface layer of a steel structure building in any of the above embodiments, and the method includes the following steps:
