Description

Technical Field

[0001] The present invention relates to the technical field of shear walls, and particularly relates to a prefabricated profiled steel sheet composite shear wall and a construction method thereof. Background Art

[0002] The lateral force resisting system of a building structure determines the seismic performance of the structure. As an efficient lateral force resisting system, the steel plate shear wall has been paid more and more attention. In addition to being used in the construction of new structures, it can also be used for the reinforcement of building structures after an earthquake. The steel plate shear wall uses steel plates as the outer steel plates, forms a steel box body with the edge column members on both sides, pours concrete inside, and forms a good whole through the bonding between the concrete and the steel plates. The outer steel plates can also be used as the formwork for pouring concrete, saving materials. Compared with the traditional lateral force resisting system, the steel plate shear wall has the advantages of large initial stiffness, good ductility, strong energy dissipation capacity, light weight, small thickness and convenient construction.

[0003] The existing prefabricated profiled steel sheet shear walls mainly use open profiled steel sheets. The upper wall and the lower wall are connected through connecting plates at each groove, and tension components are evenly distributed on the wall to restrain the concrete. However, the connecting pieces of this prefabricated profiled steel sheet shear wall are several discontinuous small steel plates, with more construction steps, troublesome installation, and lack of good integrity. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a prefabricated profiled steel sheet composite shear wall, which has the advantages of light weight and high strength, good connection, smooth surface, good shear and seismic resistance performance, simple assembly and reasonable force of components.

[0005] Another purpose of the present invention is to provide a construction method for the above-mentioned prefabricated profiled steel sheet composite shear wall.

[0006] The technical solution of the present invention is as follows: a prefabricated profiled steel sheet composite shear wall, comprising a first profiled steel sheet, a second profiled steel sheet, edge steel columns, connecting steel plates, a plurality of vertical inserts, a plurality of horizontal inserts and a plurality of tension bolts; the first profiled steel sheet and the second profiled steel sheet are stacked in the vertical direction and there is a joint seam at the stacking position, the edge steel columns are located on both sides of the first profiled steel sheet and the second profiled steel sheet, and the connecting steel plates cover the joint seam; both ends of the plurality of horizontal inserts are respectively provided with first insertion holes, and the horizontal inserts sequentially penetrate through the connecting steel plates and the first profiled steel sheet to connect the two, and the first insertion holes at both ends of the horizontal inserts are exposed to the outside, the vertical inserts are inserted into the first insertion holes, and the tension bolts sequentially penetrate through the vertical inserts, the connecting steel plates and the second profiled steel sheet to connect the three; both the first profiled steel sheet and the second profiled steel sheet adopt closed profiled steel sheets, and there are concrete cavities respectively inside the first profiled steel sheet and the second profiled steel sheet, and concrete is filled in the concrete cavities. The internal force at the joint seam of the first profiled steel sheet and the second profiled steel sheet of the present invention is jointly transmitted through the connecting steel plates, tension bolts and concrete, so that the load is transmitted more effectively; the connecting steel plates and the first profiled steel sheet are connected by horizontal inserts, and the inserts play the role of stiffeners inside the wall and have better shear resistance. The connecting steel plates and the second profiled steel sheet are connected by tension bolts, and the tension bolts can restrain the concrete in the cavity, thereby improving the overall performance and strength of the shear wall, and reducing the steel ratio and weight of the shear wall.

[0007] Further, the vertical insert includes a main body part and a plug-in part, the cross-sectional area of the main body part is larger than the cross-sectional area of the first insertion hole, the bottom surface of the main body part abuts against the top surface of the horizontal insert, and the plug-in part is inserted into the first insertion hole. The main body part naturally abuts against the top surface of the horizontal insert by gravity, without positioning the vertical insert and the horizontal insert, reducing the assembly difficulty.

[0008] Further, the main body parts between adjacent two vertical inserts are connected to each other. Connecting a plurality of vertical inserts into one body reduces the number of assembly parts and assembly steps.

[0009] Further, the cross-sectional area of the plug-in part matches the cross-sectional area of the first insertion hole, preventing the plug-in part from shaking after being inserted into the first insertion hole and enhancing the connection strength between the vertical insert and the horizontal insert.

[0010] Further, the prefabricated profiled steel sheet composite shear wall further includes a plurality of diagonal bracing steel plates, and the plurality of diagonal bracing steel plates are respectively arranged along the diagonals of the first profiled steel sheet and the second profiled steel sheet. By arranging the diagonal bracing steel plates, the wall has better shear resistance.

[0011] Further, the tension bolts sequentially penetrate through the diagonal bracing steel plates and the first profiled steel sheet to connect the two, and the tension bolts sequentially penetrate through the diagonal bracing steel plates and the second profiled steel sheet to connect the two. The tension bolts have a restraining effect on the concrete, and arranging the tension bolts along the diagonal bracing steel plates makes the restraint on the concrete stronger.

[0012] Further, a plurality of second jacks are preset near the joint seam of the first profiled steel sheet, a plurality of third jacks are preset on the connecting steel sheet corresponding to the second jacks, and the transverse inserting plate passes through the second jacks and the third jacks. By presetting the second jacks and the third jacks, the assembly difficulty is reduced and the assembly efficiency is improved.

[0013] Further, a plurality of first bolt holes are preset near the joint seam of the second profiled steel sheet, a plurality of second bolt holes are preset on the connecting steel sheet corresponding to the first bolt holes, and a third bolt hole is preset on the vertical inserting plate corresponding to the second bolt hole. The tension bolt passes through the first bolt hole, the second bolt hole and the third bolt hole. By presetting the first bolt hole, the second bolt hole and the third bolt hole, the assembly difficulty is reduced and the assembly efficiency is improved.

[0014] The present invention also provides another technical solution: a construction method of the above-mentioned assembled profiled steel sheet composite shear wall, including the following steps:

[0015] Step S1: Hoist the first profiled steel sheet and the second profiled steel sheet between two edge steel columns respectively, and stack the first profiled steel sheets vertically above the second profiled steel sheet;

[0016] Step S2: Cover the connecting steel sheet on the joint seam of the stacked first profiled steel sheet and the second profiled steel sheet, and then sequentially penetrate the transverse inserting plate through the connecting steel sheet and the first profiled steel sheet to connect the two, and the first jacks at both ends of the transverse inserting plate are exposed to the outside;

[0017] Step S3: Insert the vertical inserting plate into the first jack in the vertical direction, and sequentially penetrate the tension bolt through the vertical inserting plate, the connecting steel sheet and the second profiled steel sheet to connect the three;

[0018] Step S4: Finally, fill the concrete cavity with concrete and wait for the concrete to set.

[0019] The present invention has the following beneficial effects compared with the prior art:

[0020] For the assembled profiled steel sheet composite shear wall of the present invention, both the first profiled steel sheet and the second profiled steel sheet adopt closed profiled steel sheets, the surface is flat, and only one connecting steel sheet is needed to completely cover the joint seam, so that the wall has good integrity.

[0021] For the assembled profiled steel sheet composite shear wall of the present invention, the internal force at the joint seam of the first profiled steel sheet and the second profiled steel sheet is jointly transmitted through the connecting steel sheet, the tension bolt and the concrete, so that the load is transmitted more effectively.

[0022] The prefabricated profiled steel sheet composite shear wall of the present invention has the connecting steel plate and the first profiled steel sheet connected by a transverse insertion plate. The insertion plate acts as a stiffening rib inside the wall, having better shear resistance. The connecting steel plate and the second profiled steel sheet are connected by tension bolts. The tension bolts can restrain the concrete in the cavity, thereby improving the overall performance and strength of the shear wall, and reducing the steel ratio and weight of the shear wall.

[0023] For the prefabricated profiled steel sheet composite shear wall of the present invention, diagonal bracing steel plates are arranged along the diagonals of the first profiled steel sheet and the second profiled steel sheet, and tension bolts are arranged along the diagonal bracing steel plates. By providing the diagonal bracing steel plates, the wall has better shear resistance, and the tension bolts have a stronger restraining effect on the concrete. Brief Description of the Drawings

Detailed Description of the Embodiments

[0030] The following will further describe the present invention in detail in conjunction with the embodiments, but the implementation manners of the present invention are not limited thereto.

[0031] Embodiment 1

[0032] As Figure 1 and Figure 2 shown, this embodiment provides a prefabricated profiled steel sheet composite shear wall, including a first profiled steel sheet 1, a second profiled steel sheet 2, an edge steel column 3, a connecting steel plate 4, a plurality of vertical insertion plates 5, a plurality of transverse insertion plates 6 and a plurality of tension bolts 7.

[0033] As Figure 1 and Figure 2 shown, the first profiled steel sheet and the second profiled steel sheet are stacked vertically, with the first profiled steel sheet above the second profiled steel sheet. There is a joint seam 8 at the stacking position of the first profiled steel sheet and the second profiled steel sheet. The connecting steel plate covers the joint seam. The edge steel columns are assembled on both sides of the first profiled steel sheet and the second profiled steel sheet. Both the first profiled steel sheet and the second profiled steel sheet adopt closed profiled steel sheets. There are concrete cavities 9 respectively inside the first profiled steel sheet and the second profiled steel sheet, and concrete 10 is filled in the concrete cavities. Both the first profiled steel sheet and the second profiled steel sheet adopt closed profiled steel sheets with a flat surface. Only one connecting steel plate is needed to completely cover the joint seam, making the wall have good integrity.

[0034] As Figure 1 and Figure 2 shown, first jacks 11 are provided at both ends of multiple transverse inserting plates. The transverse inserting plates sequentially penetrate through the connecting steel plate and the first profiled steel sheet to connect the two. The first jacks at both ends of the transverse inserting plates are exposed to the outside.

[0035] As Figure 1 and Figure 2 shown, the vertical inserting plate includes a main body part 12 and a plugging part 13. The cross-sectional area of the main body part is larger than that of the first jack. The bottom surface of the main body part abuts against the top surface of the transverse inserting plate. The plugging part is inserted into the first jack. The main body part naturally abuts against the top surface of the transverse inserting plate by gravity, without the need to position the vertical inserting plate and the transverse inserting plate, reducing the assembly difficulty. In this embodiment, the main body parts between adjacent two vertical inserting plates are connected to each other, connecting multiple vertical inserting plates into one body, reducing the assembly parts and assembly steps.

[0036] As Figure 1 and Figure 2 shown, in this embodiment, multiple second jacks 14 are preset near the joint seam on the first profiled steel sheet, multiple third jacks 15 are preset on the connecting steel plate corresponding to the second jacks, and the transverse inserting plate passes through the second jacks and the third jacks. By presetting the second jacks and the third jacks, the assembly difficulty is reduced and the assembly efficiency is improved; multiple first bolt holes 16 are preset near the joint seam on the second profiled steel sheet, multiple second bolt holes 17 are preset on the connecting steel plate corresponding to the first bolt holes, and multiple third bolt holes 18 are preset on the plugging part corresponding to the second bolt holes. As Figure 3 shown, the tension bolt passes through the first bolt hole, the second bolt hole and the third bolt hole. By presetting the first bolt hole, the second bolt hole and the third bolt hole, the assembly difficulty is reduced and the assembly efficiency is improved.

[0037] The construction method of the above prefabricated profiled steel sheet composite shear wall includes the following steps:

[0038] Step S1: Hoist the first profiled steel sheet and the second profiled steel sheet between two edge steel columns respectively. The first profiled steel sheet is stacked vertically above the second profiled steel sheet.

[0039] Step S2: Cover the connecting steel plate onto the joint seam at the stacking position of the first profiled steel sheet and the second profiled steel sheet. Then, insert the transverse insertion plate through the third jack and the second jack in sequence to connect the connecting steel plate with the first profiled steel sheet. The first jacks at both ends of the transverse insertion plate are exposed to the outside.

[0040] Step S3: Insert the insertion part vertically into the first jack. The main body naturally abuts against the top surface of the transverse steel plate under the action of gravity to complete the positioning of the vertical insertion plate and the transverse insertion plate. The tension bolt passes through the third bolt hole, the second bolt hole and the first bolt hole in sequence to connect the vertical insertion plate, the connecting steel plate and the second profiled steel sheet.

[0041] Step S4: Finally, fill the concrete cavity with concrete. Wait for the concrete to solidify, and the construction of the shear wall is completed.

[0042] For the shear wall obtained by the above construction method, the stacking position of the first profiled steel sheet and the second profiled steel sheet has stronger shear resistance.

[0043] Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that the prefabricated profiled steel sheet composite shear wall further includes a diagonal bracing steel plate 19, as shown in Figure 4 and Figure 5 shown. The diagonal bracing steel plate is arranged along the diagonal of the first profiled steel sheet and the second profiled steel sheet. The tension bolt passes through the diagonal bracing steel plate and the first profiled steel sheet in sequence to connect the two. The tension bolt passes through the diagonal bracing steel plate and the second profiled steel sheet in sequence to connect the two. By setting the diagonal bracing steel plate, the wall has better shear resistance. The tension bolt has a restraining effect on the concrete. Arranging the tension bolts along the diagonal bracing makes the concrete have a stronger restraining effect.

[0045] As described above, the present invention can be preferably realized. The above embodiments are only the preferred embodiments of the present invention and are not used to limit the implementation scope of the present invention; that is, all equal changes and modifications made according to the content of the present invention are covered by the scope required to be protected by the claims of the present invention.
