Description

Technical Field

[0001] The present invention relates to the technical field of shear walls, and specifically to a foam steel plate shear wall structure. Background Art

[0002] The lateral force resisting structure is a structural functional component in a building structure used to resist lateral loads (such as wind loads and seismic loads). For high-rise buildings and steel structure buildings, the lateral force resisting structure is the key to the entire structural design.

[0003] As an important lateral force resisting structure, the shear wall is also called a wind wall, a seismic wall or a structural wall. The shear wall is a wall in a building or structure that mainly bears the horizontal load and vertical load (gravity) caused by wind load or seismic action, preventing the structure from shear (shearing) failure. It is divided into plane shear walls and tube shear walls. Plane shear walls are used in reinforced concrete frame structures, lift slab structures, and flat slab floor systems. Tube shear walls are used in high-rise buildings, high-rise structures and suspension structures, surrounded by partition walls of elevator shafts, stairwells, equipment and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls, and their stiffness and strength can withstand larger horizontal loads compared to plane shear walls.

[0004] The foam steel plate is pressed by two upper and lower metal panels and a middle polymer heat insulation inner core. It has the characteristics of simple installation, light weight, environmental protection and high efficiency. Moreover, the closed cell molecular structure used in the filling system can prevent the condensation of water vapor. The foam steel plate not only has the high mechanical strength and easy forming performance of steel materials, but also has the good decorative and corrosion resistance properties of coating materials. The foam steel plate is an emerging material highly regarded in the world today. With the progress of technology, the enhancement of environmental awareness, and the improvement of people's living standards, foam steel plate movable houses are showing more and more powerful vitality and broad market prospects, and are applied in the fields of construction, household appliances, mechanical and electrical, transportation, interior decoration, office appliances and other industries.

[0005] A patent document with the publication number CN104790563B, a foam steel plate shear wall structure, can prevent the shear wall from buckling under lateral and vertical loads by increasing the plate thickness of the shear wall without increasing its own weight; during the lateral force resistance process, no tensile field is formed in the foam steel plate shear wall, so there is no need to additionally strengthen the outer steel frame in the design; the excellent energy dissipation capacity of the foam steel can improve the seismic performance of the steel plate shear wall; the foam steel has a high specific stiffness and can provide sufficient elastic stiffness for the structure; when used in the core tube of the structure, the excellent sound insulation performance and damping of the foam steel can reduce the vibration and noise caused by the operation of the elevator.

[0006] However, in the process of implementing the above technical solutions, the following technical problems are found in the above technical solutions:

[0007] The foam steel plate shear wall structure forms a shear wall structure by installing foam steel plates between adjacent steel beams and adjacent steel columns. It can increase the plate thickness of the shear wall without increasing its own weight, thus effectively making up for the deficiencies of ordinary steel plate shear walls. However, in the actual application process, the installation method of the existing steel beams and steel columns supporting the foam steel plates in the existing structure is limited by the high height and large width of the shear wall, and it is difficult to use the frame formed by a single steel beam and steel column to complete the erection work of the foam steel plates and maintain the structural strength. Summary of the Invention

[0008] In order to overcome the deficiencies that in the actual application process of the existing foam steel plate shear wall structure, the installation method of the existing steel beams and steel columns supporting the foam steel plates in the existing structure is limited by the high height and large width of the shear wall, and it is difficult to use the frame formed by a single steel beam and steel column to complete the erection work of the foam steel plates and maintain the structural strength, the embodiment of the present application provides a foam steel plate shear wall structure. By using a plurality of angle steel bars and a plurality of column steel bars assembled in the vertical direction and cooperating with a plurality of support cross beams arranged in the horizontal direction to form a frame, the assembly work of a plurality of foam steel plates can be supported. The size of the frame can be controlled by the number of column structures arranged in the horizontal direction and the number of corner column structures arranged in the vertical direction, which is beneficial for building shear walls with large spans and high heights and is relatively flexible.

[0009] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0010] A foam steel plate shear wall structure includes a corner column structure, a column structure, and a partition cross beam structure, and there are two corner column structures;

[0011] There are a plurality of column structures, which are arranged in a line between the two corner column structures;

[0012] The partition cross beam structure is arranged inside the two corner column structures and the plurality of column structures;

[0013] The column structure includes a plurality of column steel bars, and the corner column structure includes a plurality of angle steel bars;

[0014] Among them, the plurality of column steel bars and the plurality of angle steel bars are all stacked and assembled and fixed in the vertical direction. The column steel bars and adjacent angle steel bars in the horizontal direction, and between adjacent two column steel bars are all connected with foam steel plates in an assembled manner. The partition cross beam structure is located between the upper and lower adjacent two foam steel plates and is assembled between the adjacent two column steel bars and adjacent two angle steel bars in the vertical direction.

[0015] In a possible implementation manner, a receiving strip groove extending to its surface is processed inside each of the plurality of column steel bars, and bolts pass through the inside on both sides of the column steel bars and are threadedly connected to the inside of the foam steel plates.

[0016] In a possible implementation, a receiving angle groove is machined inside the corner of the angle steel bar, and a plurality of insertion holes are machined on two sides of the angle steel bar; the plurality of insertion holes are arranged at equal intervals in the vertical direction, and bolts pass through the inside of the insertion holes and are threadedly connected to the inside of the foam steel plate.

[0017] In a possible implementation, the partition cross beam structure includes a plurality of support cross beams, and extension plates are integrally formed at both ends of the plurality of support cross beams; the two extension plates on the support cross beam are arranged at different positions up and down, and the two support cross beams can be connected end to end through the extension plates.

[0018] In a possible implementation, two support cross beams arranged in a row are connected between two adjacent upper and lower column steel bars, and pads are arranged at the vacant positions at one end of the two support cross beams, so that the two support cross beams lean on each other and are supported between two adjacent upper and lower column steel bars.

[0019] In a possible implementation, when a plurality of the foam steel plates are spliced into a plate shape, when one end of the support cross beam is located between two adjacent upper and lower angle steel bars, by filling a pad at one end of the support cross beam, the support cross beam is supported between the two angle steel bars.

[0020] In a possible implementation, the angle steel bar located below and the bottom of the column steel bar are assembled and connected to the same base, and bolts pass through the inside of the base and are connected to the ground, and the heads of the bolts are countersunk into the inside of the base, so that the top surface of the base is attached to the bottom surface of the foam steel plate.

[0021] In a possible implementation, a plurality of insertion holes located on two sides of the angle steel bar are arranged staggeredly. When a plurality of the foam steel plates are used to build a cylindrical shear wall, bolts pass through the inside of the insertion holes and are connected to the foam steel plates on two adjacent shear walls, and the bolt heads are arranged staggeredly inside the receiving angle groove.

[0022] In a possible implementation, when a plurality of the foam steel plates are used to build a cylindrical shear wall, one end of the foam steel plate extends into the two support cross beams between two adjacent upper and lower angle steel bars, and the two ends are connected complementarily to support between the two angle steel bars.

[0023] In a possible implementation, after a plurality of the foam steel plates are supported and built into a shear wall by the corner column structure, the partition cross beam structure and the column structure, a decorative panel is laid on the surface of the shear wall to block the bolts, steps and edges.

[0024] The beneficial effects of this application are:

[0025] First, in this solution, by using multiple angle steel bars and multiple column steel bars assembled vertically, and cooperating with multiple support crossbeams arranged horizontally (and connected and fixed to the angle steel bars and column steel bars) to form a framework, the assembly work of multiple foam steel plates can be supported. The size of the framework can be controlled by the number of columns arranged horizontally in the column structure and the number of corner columns arranged vertically in the vertical direction, which is beneficial for building shear walls with large spans and high heights and is relatively flexible.

[0026] Second, in this solution, when constructing a cylindrical shear wall by using multiple foam steel plates, multiple corner column structures, multiple partition crossbeam structures, and multiple column structures, the ends of two support crossbeams with one end extending between two adjacent angle steel bars above and below are connected and complemented to support between the two angle steel bars, which can ensure the structural strength of the cylindrical shear wall.

Detailed Embodiments

[0033] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0034] Embodiment 1:

[0035] This embodiment introduces the specific structure of a foam steel plate shear wall structure, specifically referring to Figures 1 - 3As shown in the figure, it includes two corner column structures 2, multiple column structures 3 arranged in a line between the two corner column structures 2, and a partition crossbeam structure 1 (arranged inside the two corner column structures 2 and the multiple column structures 3). The column structure 3 includes multiple column steel bars 301, and the corner column structure 2 includes multiple angle steel bars 201;

[0036] Among them, by stacking and assembling and fixing multiple column steel bars 301 and multiple angle steel bars 201 vertically, and by assembling and connecting foam steel plates 7 between the column steel bars 301 and adjacent angle steel bars 201 in the horizontal direction, and between adjacent two column steel bars 301, a single-sided shear wall can be formed indoors between the partition crossbeam structure 1 and the two adjacent foam steel plates 7 above and below, and assembled between two adjacent column steel bars 301 and two adjacent angle steel bars 201 in the vertical direction;

[0037] Secondly, by processing a receiving strip groove 8 extending to its surface inside multiple column steel bars 301, when bolts pass through the inside of both sides of the column steel bar 301 and are threadedly connected to the inside of the foam steel plate 7, the heads of the bolts can be received inside the receiving strip groove 8 to complete the connection work between the column steel bar 301 and two adjacent foam steel plates 7 in the horizontal direction;

[0038] Furthermore, by processing a receiving angle groove 5 inside the corner of the angle steel bar 201, and processing multiple insertion holes 6 on both sides of the angle steel bar 201, since the multiple insertion holes 6 are arranged at equal intervals in the vertical direction, when bolts pass through the inside of the insertion holes 6 and are threadedly connected to the inside of the foam steel plate 7, it can ensure that the positions at different heights at the edge of the foam steel plate 7 are all connected and fixed to the receiving angle groove 5;

[0039] As Figures 1 to 4 shown, the partition crossbeam structure 1 includes multiple support crossbeams 101, and extension plates 102 are integrally formed at both ends of the multiple support crossbeams 101;

[0040] Among them, by arranging the two extension plates 102 on the support crossbeam 101 at different positions up and down, the adjacent two support crossbeams 101 can be connected end to end through the extension plates 102, ensuring that the thickness of the connection point is the same as the thickness of the support crossbeam 101 to adapt to being supported between two adjacent foam steel plates 7 above and below, two adjacent column steel bars 301, and two adjacent angle steel bars 201;

[0041] Secondly, by connecting two support crossbeams 101 arranged in a line between two adjacent column steel bars 301, and arranging a backing plate 103 at the vacant position at one end of each of the two support crossbeams 101, with the filling of the backing plate 103, the two support crossbeams 101 can lean on each other and be supported between two adjacent column steel bars 301, ensuring that there is support between two adjacent column steel bars 301;

[0042] Meanwhile, when multiple foam steel plates 7 are spliced into a plate shape, when one end of the support cross beam 101 is located between two adjacent angle steel bars 201 up and down, by filling a cushion plate 103 at one end of the support cross beam 101, the support cross beam 101 is supported between the two angle steel bars 201;

[0043] In some examples, the angle steel bar 201 located below and the bottom of the column steel bar 301 are assembled and connected to the same base 4. By passing a bolt through the inside of the base 4 and connecting it to the ground, the base 4 can be fixed to the ground (in this state, the head of the bolt is countersunk into the inside of the base 4, so that the top surface of the base 4 fits against the bottom surface of the foam steel plate 7).

[0044] The above design forms a framework by using multiple angle steel bars 201 and multiple column steel bars 301 assembled in the vertical direction, in cooperation with multiple support cross beams 101 arranged in the horizontal direction and connected and fixed to the angle steel bars 201 and the column steel bars 301 (adjacent two support cross beams 101 are connected end to end by an extension plate 102, and the vacant part at one end of the support cross beam 101 is filled with a cushion plate 103 to ensure that there is support between two adjacent column steel bars 301 and two angle steel bars 201 up and down), thereby supporting the assembly work of multiple foam steel plates 7. The size of the framework can be controlled by the number of column structures 3 arranged in the horizontal direction and the number of corner column structures 2 arranged in the vertical direction, which is beneficial to building shear walls with large spans and high heights. The applied column structure 3, corner column structure 2, and partition cross beam structure 1 can be increased or decreased according to actual situations and assembled, which is relatively flexible.

[0045] Embodiment 2:

[0046] Based on Embodiment 1, as Figures 1 to 3 、 Figure 5 shown, this embodiment introduces the specific structures of the angle steel bar 201, the support cross beam 101, and the foam steel plate 7. A plurality of insertion holes 6 at two sides of the angle steel bar 201 are arranged staggeredly;

[0047] Among them, when multiple foam steel plates 7 are used to build a cylindrical shear wall, bolts pass through the inside of the insertion holes 6 and are connected to the foam steel plates 7 on two adjacent shear walls. The bolt heads are arranged staggeredly inside the receiving angle grooves 5 to prevent interference when the bolts pass through the insertion holes 6 from the inside of the receiving angle grooves 5 and are connected to the foam steel plates 7;

[0048] Secondly, when multiple foam steel plates 7 are used to build a cylindrical shear wall, one ends of two support cross beams 101 extending into the space between two adjacent angle steel bars 201 up and down are complementary to each other to support between the two angle steel bars 201, which can ensure the structural strength of the cylindrical shear wall built by the column structure 3, the corner column structure 2, the partition cross beam structure 1, and the foam steel plate 7;

[0049] In some examples, after a shear wall is supported and erected by multiple foam steel plates 7 formed by corner column structures 2, partition cross beam structures 1 and column structures 3, decorative panels are laid on the surface of the shear wall to block bolts, steps and edges, which can ensure the appearance beauty of the shear wall.

[0050] When constructing a cylindrical shear wall by using multiple foam steel plates 7, multiple corner column structures 2, multiple partition cross beam structures 1 and multiple column structures 3, the above design enables one end of two support cross beams 101 extending into the space between two adjacent angle steel bars 201 above and below to be joined and complemented with each other, so as to be supported between the two angle steel bars 201, which can ensure the structural strength of the cylindrical shear wall;

[0051] Meanwhile, when erecting the cylindrical shear wall, when the foam steel plates 7 on two adjacent shear walls are connected to the same angle steel bar 201, the bolts passing through multiple through holes 6 in the receiving corner groove 5 are staggered, which can avoid interference of the bolts inside the receiving corner groove 5.

[0052] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
