Description

Technical Field

[0001] This disclosure relates to the field of steel structure buildings, and more particularly to a steel structure wall and a modular steel-concrete composite building structure. Background Technology

[0002] Currently, steel structure housing is mainly used in low-rise buildings such as villas and new rural housing, accounting for less than 2% of the overall housing market. The main reasons are as follows: 1. Steel structures have poor fire resistance and corrosion resistance, and the cost of ensuring these properties is too high, making steel structure housing significantly more expensive than reinforced concrete buildings; 2. Since steel structure housing is mostly steel frame structure, it has high requirements for unit layout, resulting in serious issues with exposed beams and columns; 3. Due to the poor sound insulation performance of steel, steel structure housing generally has sound insulation problems, affecting the residents' experience; 4. The tensile strength of steel is much stronger than its compressive strength, therefore steel structures are not suitable for high-rise buildings. While reinforced concrete core tubes can be used for public buildings, they lead to a larger shared area in residential buildings.

[0003] Chinese utility model patent CN206737201 U discloses a lattice-type steel tube bundle concrete composite structure. This utility model uses an outer steel tube bundle with internal concrete pouring, solving problems such as steel structure unit layout and shared area issues. It allows for 2-3 floors to be hoisted at once, resulting in faster construction speed. However, this lattice-type steel tube bundle concrete composite structure still has the following problems: 1. Sound insulation issues; 2. Beam and slab installation involves high-altitude work, requiring excessive precision and posing safety risks; 3. Large steel usage, leading to high costs; 4. Only vertical construction is addressed; floor slab construction is complex and takes significantly longer than wall construction, severely impacting overall construction efficiency.

[0059] The beneficial effects of this invention are as follows:

[0060] 1. The modular steel-concrete composite building structure disclosed herein adopts modular production, and is assembled in the factory on a room-by-room basis. The complex on-site steel reinforcement and carpentry work is completely moved to the factory, and only steel structure assembly and concrete pouring need to be completed on-site. The components are industrially produced, and most of them are standard parts, which are convenient to produce and are suitable for current mainstream steel processing machinery, requiring less manpower.

[0061] 2. Concrete is poured into the hollow part of the steel plate afterward. The wall concrete is connected to the floor slab concrete, which has good waterproof performance. Moreover, the steel is cut off by the concrete inside, so there is no sound insulation problem.

[0062] 3. The load-bearing performance of steel structure walls is closer to that of reinforced concrete shear walls. There are no issues with exposed beams or columns. The thickness of steel structure walls is less than that of reinforced concrete shear walls, resulting in a smaller shared area compared to reinforced concrete residential buildings. Furthermore, it can be used in most apartment layouts and has high acceptance in architectural design.

[0063] 4. The integrated decorative panel in this disclosure is convenient for transportation and installation, and can solve the problems of corrosion and fire prevention of steel structures, as well as the problem of difficulty in drilling holes in steel plates.

[0064] 5. The floor slabs in this disclosure do not use a stacking method, reducing the overall weight of the modules and facilitating transportation and adjustment. The placement and processing of reinforcing bars are convenient, and the connections between pipelines are reliable. Attached Figure Description

Detailed Implementation

Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0079] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] like Figure 3 , 4 As shown in Figure 5, according to the first embodiment of this disclosure, a steel structure wall 24 is provided, comprising: two opposing steel plates 3 on the wall, and lattice columns 1 and lattice beams 2 disposed between the two steel plates 3; a first cavity 5 is formed between the two steel plates 3, and the two steel plates 3 are respectively connected to the lattice columns 1 and / or the lattice beams 2, and the two steel plates 3 are connected by tie bolts 4; two lattice columns 1 and two lattice beams 2 are respectively provided, the two lattice columns 1 and the two lattice beams 2 form a rectangular frame, and the two lattice columns 1 are opposite to each other, and the two lattice beams 2 are opposite to each other.

[0081] The steel plate 3 on the wall can be connected to the lattice column 1 and / or lattice beam 2 by welding or bolting; the two steel plates 3 on the wall are connected together by tie bolts 4 so that the surfaces of the two steel plates 3 on the wall are as flat as possible.

[0082] In one implementation, such as Figure 4 As shown, at least one of the steel plates 3 on the wall may include an upper steel plate 3a and a lower steel plate 3b arranged sequentially from top to bottom; the upper steel plate 3a and the lower steel plate 3b are joined side by side to form the steel plate 3 on the wall. Thus, when connecting the upper and lower steel structure walls 24 or adjusting the height, the lower steel plate 3b can be removed to allow tools to be inserted into the first cavity 5 for operation. After installation, the lower steel plate 3b is connected to the lattice column 1 and / or lattice beam 2 by welding or bolting.

[0083] In one implementation, such as Figure 9 As shown, the lattice column 1 includes four vertically arranged first angle steels 1a; the four first angle steels 1a are paired opposite each other to form a cuboid-shaped second cavity; multiple first connecting plates 1b are provided between any two adjacent first angle steels 1a; each first connecting plate 1b is connected to two adjacent first angle steels 1a at both ends. In this embodiment, the first angle steels 1a are equilateral angle steels with a width of 20-75mm and a thickness of 3-10mm; the first connecting plates 1b are steel plates with a length of 180-400mm and a thickness of 3-10mm; the first connecting plates 1b are connected to two adjacent first angle steels 1a by welding. The lattice columns 1 between the steel structure walls 24 can be connected together by welding or bolting.

[0084] In one embodiment, the included angle between the first connecting plate 1b and the first angle steel 1a connected thereto is 30°-90°.

[0085] In one implementation, such as Figure 3 As shown, it also includes: two opposing lattice columns 7 and two opposing lattice beams 8; both the two lattice columns 7 and the two lattice beams 8 are located within a rectangular frame, and the two lattice columns 7 and the two lattice beams 8 are connected sequentially to form a rectangular opening 6; both ends of each lattice column 7 extend vertically and connect to the two lattice beams 2; and / or, both ends of each lattice beam 8 extend horizontally and connect to the two lattice columns 7. Figure 5 As shown, sealing plates 10 are welded to the four side walls of the rectangular hole 6 to form a hole structure such as a door or window.

[0086] In one implementation, such as Figure 3As shown, the lattice beam 2 includes two horizontally arranged second angle steels 2a and a plurality of second connecting plates 2b disposed between the two second angle steels 2a; the two second angle steels 2a are arranged opposite each other; each end of the second connecting plate 2b is connected to the two second angle steels 2a respectively. In this embodiment, the second angle steels 2a are equilateral angle steels with a width of 20-75mm and a thickness of 3-10mm; the second connecting plates 2b are steel plates with a length of 180-400mm and a thickness of 3-10mm; the second connecting plates 2b are connected to the two adjacent second angle steels 2a by welding.

[0087] In one embodiment, the included angle between the second connecting plate 2b and the second angle steel 2a connected thereto is 30°-90°.

[0088] In one embodiment, the first cavity 5 is filled with concrete to achieve waterproofing and sound insulation. The concrete can be ordinary concrete, or it can be ceramsite concrete or EPS filler concrete.

[0089] In one embodiment, shear connectors are attached to the side of the steel plate 3 facing the first cavity 5 to ensure a reliable connection between the steel plate 3 and the concrete. Shear connectors include, but are not limited to, rivets and shear studs.

[0090] like Figure 1 , 2 As shown in Figure 7, this disclosure also provides a modular steel-concrete composite building structure, including multiple connected room modules; the room modules are functionally divided into a living room module 34, a bedroom module, a bathroom module 32, a kitchen module 37, a staircase module 36, and an elevator module 35; each room module includes: multiple walls and a floor slab 25 connected to the upper end of the walls, at least one of the multiple walls is an exterior wall, and the exterior wall is a steel structure wall 24 as described above.

[0091] In one implementation, such as Figure 8 As shown, in the multi-wall structure, except for the outer wall, all other walls include inner wall steel plates 9, which enclose the interior space. Each of the four ends of the inner wall steel plate 9 facing away from the interior space is connected to a third angle steel 29, which are joined end-to-end to form a rectangle. By incorporating four third angle steels 29 into the inner wall steel plate 9, its bending strength is increased, preventing warping and deformation when connecting the inner wall steel plates 9 corresponding to two room modules.

[0092] When the inner wall steel plate 9 does not require reinforcement, two of the four third angle steels 29 are arranged at the junction of the inner wall steel plate 9 and the wall, thereby connecting the inner wall steel plate 9 and the corresponding wall through the third angle steels 29 at the junction. It should be noted that the wall here refers to either the inner wall steel plate 9 or the outer wall. That is, when the inner wall steel plate 9 is connected to the outer wall, the third angle steel 29 is set at the junction of the inner wall steel plate 9 and the outer wall; when the inner wall steel plates 9 are connected to each other, the third angle steel 29 is set between the inner wall steel plates 9.

[0093] When the inner wall steel plate 9 needs reinforcement, such as Figure 8 As shown, multiple fourth angle steels 30 are provided on the side of the inner wall steel plate 9 away from the indoor space. The fourth angle steels 30 are arranged vertically and are located within the four third angle steels 29.

[0094] When steel structure walls 24 are assembled into room modules, if there are two or more steel structure walls 24, the lattice column 1 of one steel structure wall 24 can abut against the steel plate 3 on the wall of another steel structure wall 24; or, as... Figure 8 As shown, a rectangular cavity is formed between the lattice columns 1 of two adjacent steel structure walls 24, and the lattice columns 1 are placed inside the rectangular cavity.

[0095] In one embodiment, the inner wall steel plate 9 has multiple reserved bolt holes on its surface, so that when connecting two room modules, the inner wall steel plates 9 corresponding to the two room modules can be connected together by tie bolts 4.

[0096] In one implementation, such as Figure 11 As shown, the joints between two adjacent room modules are both made of inner wall steel plates 9. A third cavity 38 is formed between the inner wall steel plates 9 of the two adjacent room modules. A limiting component 39 is provided in the third cavity 38, and the limiting component 39 abuts against the two inner wall steel plates 9 forming the third cavity 38. In one embodiment, the limiting component can be the aforementioned lattice column 1, so that the inner wall steel plates 9 and lattice column 1 at the joint of the two room modules form a structure similar to a steel structure wall 24. On this basis, the two inner wall steel plates 9 forming the third cavity 38 are connected by tie bolts 4. In one embodiment, concrete is poured into the third cavity 38 to achieve waterproofing and sound insulation. The concrete can be one of ordinary concrete, ceramsite concrete, or EPS filler concrete. On this basis, a shear connector is provided on the side of the inner wall steel plate 9 facing the third cavity 38 to ensure a reliable connection between the inner wall steel plate 9 and the concrete. The shear connector includes, but is not limited to, rivets, shear studs, etc.

[0097] In one implementation, such as Figure 6As shown, the floor slab 25 includes a bottom steel plate 14, multiple upper lattice supports 11, and two layers of additional reinforcing bars 15 arranged sequentially from top to bottom. The multiple upper lattice supports 11 are arranged side by side along a first horizontal direction, and the bottom of each upper lattice support 11 is connected to the bottom steel plate 14. The two layers of additional reinforcing bars 15 are respectively connected to the upper and lower parts of the upper lattice supports. Compared with the composite floor slab 25, the floor slab 25 of this embodiment has a lower overall weight and is easier to transport and adjust.

[0098] In one implementation, such as Figure 6 As shown, each lattice support 11 on the slab includes two opposing fifth angle steels 12 and multiple third gusset plates 13 positioned between the two fifth angle steels 12; both ends of each third gusset plate 13 are connected to the two fifth angle steels 12 respectively. Water supply and drainage pipes, electrical conduits 16, and other equipment pipelines can be pre-laid on the floor slab 25. The electrical conduits 16 can pass through the gaps between the third gusset plates 13. The water supply and drainage pipes include water supply and drainage risers 17 and water supply and drainage horizontal pipes 18. The water supply and drainage horizontal pipes can be arranged between the additional reinforcing bars 15 on both sides, and the water supply and drainage risers 17 are vertically inserted into the bottom steel plate 14 of the slab.

[0099] In one embodiment, each fifth angle steel 12 is provided with a reserved hole for the additional reinforcing bar 15 to pass through, so as to facilitate the arrangement of the additional reinforcing bar 15.

[0100] In another implementation, such as Figure 7 As shown, multiple walls enclose an open interior area; the modular steel-concrete composite structure also includes multiple under-slab supports 28; the multiple under-slab supports 28 are respectively set at the top corners of the bottom steel plate 14, one end of the multiple under-slab supports 28 is detachably connected to the bottom steel plate 14, and the other end extends downward. By setting the under-slab supports 28, the deformation of the floor slab 25 during installation is greatly reduced.

[0101] In one implementation, such as Figure 7 As shown, it also includes: horizontal support 26 and vertical support 27; one end of the vertical support 27 is detachably connected to the floor slab 25, and the other end extends downward; both ends of the horizontal support 26 are detachably connected to the lower end of the under-slab support 28 and the exterior wall, respectively. The installation of horizontal support 26 and vertical support 27 ensures safe transportation and hoisting. After the poured concrete reaches 75% strength, the horizontal support 26 and vertical support 27 will be removed.

[0102] Each wall is connected with an integrated decorative panel; such as Figure 10As shown, the integrated decorative panel has pre-drilled connection holes 22 on its surface; magnetic blocks 23 are attached to the top corners of the integrated decorative panel. By setting the pre-drilled connection holes 22, the integrated decorative panel can be connected to the wall steel plate 3 or the inner wall steel plate 9 using connecting parts such as tie bolts 4. By setting the magnetic blocks 23 at the top corners of the integrated decorative panel, it is ensured that the integrated decorative panel does not warp when connected to the wall steel plate 3 or the inner wall steel plate 9.

[0103] In one implementation, such as Figure 10 As shown, the integrated decorative panel includes a steel plate front panel 19 and an interior front panel 21 arranged opposite to each other; an insulation board 20 is sandwiched between the steel plate front panel 19 and the interior front panel 21; a magnetic block 23 is connected to the steel plate front panel 19. This enables the integrated decorative panel to have a thermal insulation function.
