Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a corrugated steel plate bolt connection structure, a shear wall structure, and an assembly method. Background Technology

[0002] Longitudinal assembly of corrugated steel plates typically relies on welding and direct bolt connections. While these two techniques offer advantages such as simple construction and low cost, welding generates numerous weld seams, impacting the structure's fatigue performance. Direct bolt connections involve stacking the steel plates to be assembled, drilling holes directly into the corrugated steel plates, and then connecting them directly with bolts. For example, CN214695223U discloses a connecting corrugated plate for bridge and tunnel reinforcement, comprising multiple overlapping corrugated plates. Multiple parallel backing plates are provided at both ends of the corrugated plates, located on both sides of the overlapping portion of two corrugated plates. The backing plates have multiple through holes spaced evenly, penetrating both the backing plates and the corrugated plates. The two overlapping corrugated plates are fixed together with bolts.

[0003] For bolted connections, the cross-section of the connection hole only has two bearing surfaces of the assembled steel plates. In this case, the shear force at this point will be directly borne by the bolt and the bearing surfaces of the two steel plates. However, the corrugated steel plates used in corrugated steel plate shear wall structures are often thin. Under large loads, especially fatigue loads, the holes in the corrugated steel plates are very easy to be sheared, which can lead to the failure of the overall structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a corrugated steel plate bolt connection structure, shear wall structure, and assembly method. By connecting corrugated steel plates with limiting grooves, the mechanical properties at the longitudinal splicing joints of the corrugated steel plates are optimized, improving connection stability. Furthermore, the absence of overlapping portions between the corrugated steel plates enhances their utilization rate.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a corrugated steel plate bolt connection structure, including a connecting plate, wherein symmetrical limiting grooves are provided on both sides of the connecting plate, and the two limiting grooves are separated by a blocking part; a corrugated steel plate is inserted into each limiting groove, the corrugated steel plate abuts against the blocking part, and the connecting plate is connected to the corrugated steel plate by bolts.

[0007] As a further implementation, the shape of the connecting plate is adapted to the corrugated steel plate, and the cross-section of the connecting plate has an I-shaped structure.

[0008] As a further implementation, the connecting plate has threaded holes corresponding to the limiting groove positions, and the threaded holes are at least opened on the plane and the inclined surface of the connecting plate.

[0009] As a further implementation, after the corrugated steel plate is inserted into the limiting groove, the surface of the corrugated steel plate is in contact with the inner wall of the limiting groove.

[0010] As a further implementation, the inner surface of the limiting groove is polished to a rough surface.

[0011] As a further implementation, the depth of the limiting groove is greater than 10 to 15 times the thickness of the corrugated steel plate.

[0012] As a further implementation, the connecting plate is an integrated structure.

[0013] Secondly, embodiments of the present invention also provide a shear wall structure, including the aforementioned corrugated steel plate bolt connection structure.

[0014] Thirdly, embodiments of the present invention also provide an assembly method for the aforementioned corrugated steel plate bolt connection structure, comprising:

[0015] Insert the corrugated steel plates to be assembled into the limiting grooves on both sides of the connecting plate until they contact the blocking part, and align the corrugated steel plates with the threaded holes of the connecting plate.

[0016] Pass the bolt's shank through the threaded hole and temporarily secure it;

[0017] Tighten the nuts to connect the corrugated steel plate to the connecting plate.

[0018] As a further implementation, the connecting plate is integrally cast or manufactured using a welding process.

[0019] The beneficial effects of this invention are as follows:

[0020] (1) In this invention, the connecting plate connects two corrugated steel plates through double-sided limiting grooves. The connecting plate divides the shear force at the splicing part into two parts, which are borne by the double-sided connecting structure of the connecting plate respectively. Furthermore, each side of the connecting structure consists of two connecting plate bearing surfaces and one corrugated steel plate bearing surface, which improves the mechanical properties of the connecting structure. At the same time, the corrugated steel plate is inserted into the limiting groove to position the corrugated steel plate and ensure the assembly quality.

[0021] (2) The corrugated steel plates of the present invention are connected by an integrated connecting plate. The connecting plate has two non-through limiting grooves, so that the corrugated steel plates to be assembled do not overlap, and the corrugated steel plates can be reasonably utilized while ensuring connection stability.

[0027] Example 1:

[0028] In a typical embodiment of the present invention, such as Figures 1-3 As shown, a bolt connection structure for corrugated steel plates is presented.

[0029] The bolted connection structure introduces an integral connecting plate 2. The connecting plate 2 connects two corrugated steel plates 1 through double-sided limiting grooves 4. First, the connecting plate 2 divides the shear force at the splicing part into two parts, which are borne by the double-sided connecting structure of the connecting plate 2 respectively. Second, at the cross-section of each side of the connecting structure, it consists of two bearing surfaces of the connecting plate 2 and one bearing surface of the corrugated steel plate 1. For each bearing interface, the load it bears is only about one-third of that of the bolted direct connection structure.

[0030] This bolted connection structure optimizes the mechanical properties of the longitudinal splicing joint of the corrugated steel plate 1, and plays a significant role in optimizing and improving the overall mechanical properties, fatigue performance, and seismic performance of the corrugated steel plate 1 related structures, especially the corrugated steel plate 1 shear wall structure.

[0031] The above-mentioned corrugated steel plate bolt connection structure will now be described in detail with reference to the accompanying drawings.

[0032] like Figures 1-3 As shown, the corrugated steel plate bolt connection structure of this embodiment includes a connecting plate 2 and a corrugated steel plate 1. The shape of the connecting plate 2 is adapted to the corrugated steel plate 1, and the connecting plate 2 can be adaptively adjusted for corrugated steel plates 1 with different corrugation forms. The connecting plate 2 is made of high-performance materials and can be manufactured by integral casting or by welding process according to construction requirements.

[0033] The connecting plate 2 has symmetrically opened limit grooves 4 on both sides. The two limit grooves 4 are separated by a blocking part, that is, they are not connected, so that the cross section of the connecting plate 2 forms an I-shaped structure. The limit grooves 4 penetrate the connecting plate 2 along the length direction, which facilitates the installation of the corrugated steel plate 1.

[0034] Corrugated steel plates 1 are inserted into each limiting groove 4, and the corrugated steel plates 1 abut against the blocking part. The connecting plate 2 is connected to the corrugated steel plates 1 by bolts 3. That is, at the splicing end of the corrugated steel plates 1, by adding connecting plates 1, the two corrugated steel plates 1 are prevented from overlapping, thus increasing the utilization rate of the corrugated steel plates 1. At the same time, the limiting groove 4 plays a positioning role for the corrugated steel plates 1, which can realize the precise assembly of the corrugated steel plates 1. Then, the corrugated steel plates 1 are connected to the connecting plate 2 by bolts 3. The connecting plate 2 divides the shear force of the splicing part into two parts, which are borne by the double-sided connection structure of the connecting plate 2 respectively.

[0035] like Figure 2 and Figure 3 As shown, the connecting plate 2 has multiple rows of threaded holes 5. Considering the connection performance, threaded holes 5 are provided in both the horizontal and inclined sections of the connecting plate 2, and threaded holes 5 are provided for each limiting groove 4.

[0036] After the corrugated steel plate 1 is inserted into the limiting groove 4, the surface of the corrugated steel plate 1 fits against the inner wall of the limiting groove 4, that is, the thickness of the limiting groove 4 is adapted to the thickness of the corrugated steel plate 1, so that the two can be stably locked together; at the same time, in order to increase the friction between the corrugated steel plate 1 and the limiting groove 4 and prevent the corrugated steel plate 1 from coming out of the limiting groove 4, the inner surface of the limiting groove 4 and the splicing end of the corrugated steel plate 1 are both ground to a rough surface.

[0037] To further ensure the splicing performance between corrugated steel plates 1, the depth of the limiting groove 4 should be greater than 10 to 15 times the thickness of the corrugated steel plate 1, thereby ensuring the splicing length of the corrugated steel plate 1.

[0038] This embodiment utilizes the friction between the connecting plate 2 and the corrugated steel plate 1, as well as the bearing capacity of the bolt 3 and the threaded hole 5, to achieve effective longitudinal assembly of the corrugated steel plate 1. This improves the assembly quality and efficiency, ensures the mechanical properties of the connection structure, and extends its service life.

[0039] Example 2:

[0040] This embodiment provides a shear wall structure, including the corrugated steel plate bolt connection structure described in Embodiment 1.

[0041] Example 3:

[0042] This embodiment provides an assembly method for a corrugated steel plate bolt connection structure. The corrugated steel plate bolt connection structure is as described in Embodiment 1. The splicing ends of the corrugated steel plates 1 to be assembled are aligned longitudinally at a certain distance and inserted into the limiting groove 4 of the connecting plate 2. The bolt 3's screw 7 passes through the pre-drilled threaded hole 5 of the corrugated steel plate 1 and the connecting plate 2 from one side, and the bolt head 6 is in contact with one side surface of the connecting plate 2. Then, the nut 8 is screwed onto the screw 7 on the other side to complete the bolt connection.

[0043] Specifically, it includes the following steps:

[0044] Step 1: Corrugated steel plate 1 and connecting plate 2 are prefabricated in the factory;

[0045] Step 2: The corrugated steel plate 1 and the connecting plate 2 are threaded with holes 5 at the corresponding positions using a CNC machine tool;

[0046] Step 3: Insert the corrugated steel plate 1 to be assembled into the limiting grooves 4 on both sides of the connecting plate 2 to the bottom, and align the corrugated steel plate 1 with the threaded holes 5 on the connecting plate 2.

[0047] Step 4: The bolt 7 of bolt 3 passes through the threaded hole 5 between the corrugated steel plate 1 and the connecting plate 2 from one side and is temporarily fixed;

[0048] Step 5: Screw nut 8 onto screw 7 from the other side to complete the bolt connection.

[0049] The assembly method of this embodiment can improve the longitudinal assembly efficiency of the corrugated steel plate 1 and ensure the longitudinal assembly quality of the corrugated steel plate 1.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
