Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a high-rigidity corrugated steel plate wall. Background Technology

[0002] With the continuous improvement of economic level and engineering technology, my country's requirements for the seismic safety of building structures have also increased. As an effective seismic resistance measure, corrugated steel plate walls have been increasingly used in practical engineering projects in the past decade.

[0003] Corrugated steel plate walls are a new type of lateral force resisting system suitable for building structures, composed of embedded corrugated steel plates and vertical edge members. By bending the steel plates into "ribs," they improve lateral bearing capacity, exhibit a full hysteresis curve under cyclic loads, and have an energy dissipation capacity dozens of times higher than ordinary steel plate walls. Corrugated steel plate walls are easy to install, significantly shortening construction time for seismic reinforcement and building renovation, resulting in good economic benefits. They can be arranged without filling the entire span, facilitating the placement of door and window openings within the same frame, better meeting the building's usage needs. They are widely used in kindergartens, schools, hospitals, hotels, stadiums, and other building fields, as well as in power, aviation, and bridge engineering.

[0004] However, in some projects, the structural requirements for the lateral stiffness of the corrugated steel plate walls are too high, resulting in the corrugated steel plates needing to be 20mm, 25mm, or even 30mm thick. Bending steel plates of this thickness is extremely difficult; ordinary bending machines cannot meet the requirements, necessitating special processes. This significantly increases processing difficulty and cost, thus creating considerable obstacles to the application and promotion of this type of new technology. Utility Model Content

[0005] The purpose of this utility model is to provide a high-rigidity corrugated steel plate wall to solve the problem that in the prior art, some projects have high requirements for the thickness of the corrugated steel plate wall, which makes the processing difficult and costly.

A stiffness adjustment layer is provided on the corrugated steel plate, and there is a gap between the stiffness adjustment layer and the vertical edge members. The stiffness adjustment layer includes a main body and several connecting node units. The connection node unit includes an installation block, a connector, and lightweight concrete. Several elongated through slots are opened along the transverse direction on the corrugated steel plate. The installation block is fixedly installed on one side of the corrugated steel plate. A sliding groove communicating with the elongated through slots is provided along the transverse direction on the side wall of the installation block facing the corrugated steel plate. One end of the connector is slidably embedded in the sliding groove, and the other end passes through the elongated through slot and is fixedly connected to the main body. The lightweight concrete is poured into the sliding groove.

[0007] Furthermore, there are two mounting blocks, which are symmetrically arranged along the vertical direction, and the elongated through slots correspond one-to-one with the mounting blocks.

[0008] Furthermore, the main body is provided with V-shaped ribs, which are parallel to the corrugated steel plate, and the two relatively free ends of the V-shaped ribs are respectively fixed with support rods that support the free ends of the connectors.

The reinforcing bar layer includes horizontal reinforcing bars and vertical reinforcing bars. The horizontal reinforcing bars and vertical reinforcing bars are fixedly connected. The reinforcing bar layer is fixedly supported on V-shaped bars.

[0010] Furthermore, the main body is a concrete slab, and the steel reinforcement layer does not protrude beyond the main body.

[0011] Furthermore, the cross-section of the groove is conical, and the diameter of the groove gradually decreases from the inside to the outside.

[0012] Furthermore, the diameter of the groove opening is larger than the diameter of the elongated through groove.

[0013] Furthermore, there are two vertical edge members, which are symmetrically installed on both sides of the corrugated steel plate.

[0014] Furthermore, the vertical edge member is an I-beam, and a reinforcing assembly is provided on the I-beam.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] This embodiment proposes a high-stiffness corrugated steel plate wall, such as... Figures 1 to 7As shown, the structure includes a corrugated steel plate 1 and a vertical edge member 2. A stiffness adjustment layer is provided on the corrugated steel plate 1, and a gap exists between the stiffness adjustment layer and the vertical edge member 2 to satisfy the inter-layer displacement deformation of the structure. The stiffness adjustment layer includes a main body 4 and several connecting node units. In this embodiment, the several connecting node units are distributed in a linear array on the corrugated steel plate 1. Each connecting node unit includes two mounting blocks 5, two connectors 7, and lightweight concrete 12. The connecting node units are located at the troughs of the corrugated steel plate 1, and the two mounting blocks 5 are symmetrically arranged along the vertical direction. A number of elongated slots 3 are transversely formed along the corrugated steel plate 1, each corresponding to a mounting block 5. The mounting block 5 is fixedly installed on one side of the corrugated steel plate 1. A sliding groove 6, communicating with the corresponding elongated slot 3, is provided transversely along the side wall of the mounting block 5 facing the corrugated steel plate 1. The inner end of the connector 7 is slidably embedded in the sliding groove 6, and the outer end passes through the elongated slot 3 and extends to the other side of the corrugated steel plate 1. The free end of the connector 7 is used for fixed connection with the main body 4. Lightweight concrete 12 is poured into the sliding groove 6 to fix the connector 7 and the mounting block 5 together. In this embodiment, the mounting block 5 has a conical cross-section and is fixedly installed on the corrugated steel plate 1 by welding.

[0022] The main body 4 is provided with a V-shaped rib 8, which is parallel to the corrugated steel plate 1. The two relatively free ends of the V-shaped rib 8 are respectively fixed with support rods 9 that are supported on the free ends of the connector 7. In this embodiment, the support rods 9 are perpendicular to the corrugated steel plate 1, and the axis of the support rods 9 is collinear with the axis of the connector 7. The support rods 9 and the V-shaped rib 8 are integrally formed and are formed by bending a long straight steel bar. The support rods 9 are welded to the free ends of the connector 7. A layer of reinforcing bars parallel to the corrugated steel plate 1 is laid on the corrugated steel plate 1. The reinforcing bar layer includes horizontal reinforcing bars 10 and vertical reinforcing bars 11. The horizontal reinforcing bars 10 and vertical reinforcing bars 11 are fixedly connected. The reinforcing bar layer is fixedly supported on V-shaped bars 8. In this embodiment, the horizontal steel plate is located outside the vertical reinforcing bars 11, and each intersection between the two is firmly tied or welded with iron wire. The tip of the V-shaped bar 8 is oriented towards the center of the corrugated steel plate 1 along the transverse direction of the corrugated steel plate 1. The tip of the V-shaped bar 8 is located above the horizontal reinforcing bars 10. The two are firmly tied or welded with iron wire. The two straight segments of the V-shaped bar 8 are located below the vertical reinforcing bars 11 and are respectively firmly tied or welded to the vertical reinforcing bars 11 with iron wire. With this structural design, the V-shaped bar 8 is fixed on the connector 7 to form a stirrup, which provides stable support for the reinforcing bar layer and effectively ensures accurate control of the position of the slab reinforcing bar layer.

[0023] The main body 4 is made of concrete slab, with ordinary concrete poured inside. The steel reinforcement layer does not protrude outside the main body 4. The steel reinforcement layer and V-shaped reinforcement 8 are fixed inside the main body 4. By setting the connector 7, the V-shaped reinforcement 8 is connected to the corrugated steel plate 1, that is, the main body 4 is connected and fixed to the corrugated steel plate 1.

[0024] In the above embodiment, the V-shaped reinforcement 8 is embedded in the main body 4 in a manner parallel to the surface of the corrugated steel plate 1. At the same time, the V-shaped reinforcement 8 provides stable support for the steel reinforcement layer, so that the steel reinforcement layer is also embedded in the main body 4. The ordinary concrete of the main body 4 is poured on the corrugated steel plate 1, and together with the V-shaped reinforcement 8 and the steel reinforcement layer, it forms reinforced concrete. The overall stiffness of the stiffness adjustment layer is improved. When the corrugated steel plate 1 is subjected to out-of-plane constraint, the uniform transmission of the constraint effect can be ensured, and the constraint failure caused by local stress concentration can be avoided. The stiffness adjustment layer can resist temperature stress, shrinkage deformation and accidental loads during the construction stage, and is not easy to crack.

[0025] The cross-section of the slide 6 is conical, and the diameter of the slide 6 gradually decreases from the inside to the outside. This structural design allows the connector 7 to slide only along the extension direction of the slide 6 without detaching from the mounting block 5, which facilitates construction.

[0026] The diameter of the groove 6 opening is larger than the diameter of the elongated through groove 3. With this structural design, when the mounting block 5 is welded onto the corrugated steel plate 1, the worker has a higher tolerance for error, which can avoid the situation where the connector 7 cannot pass through the elongated through groove 3 due to some minor errors or operational mistakes.

[0027] In the above embodiment, the connector 7 includes a slider and a short steel bar. The shape of the slider matches the groove 6. The short steel bar is welded to the slider. The free end of the short steel bar passes through the elongated through groove 3 and is welded to the support rod 9.

[0028] There are two vertical edge members 2, which are symmetrically installed on both sides of the corrugated steel plate 1.

[0029] The vertical edge member 2 is an I-beam, with its web parallel to the corrugated steel plate 1. The sidewalls of the corrugated steel plate 1 are welded to the outer surface of the flange of the I-beam. A reinforcing assembly is provided on the I-beam, including a reinforcing plate 13, a stiffening plate 14, and a flange extension plate 15. The reinforcing plate 13 is vertically welded to the web of the I-beam, and the flange extension plate 15 is welded to the side of the flange of the I-beam, parallel to the reinforcing plate 13. The stiffening plate 14 is vertically welded between the reinforcing plate 13 and the flange extension plate 15, meaning the stiffening plate 14 is parallel to the web of the I-beam.

[0030] In the above embodiment, the corrugated steel plate 1 is connected to the vertical edge members 2 on the left and right sides by welding. The top and bottom of the vertical edge members 2 are flush with the top and bottom of the corrugated steel plate 1, respectively. The corrugated steel plate 1 is welded and fixed to the embedded parts in the building structure, thereby realizing the wall structure function. During welding, deformation is controlled to ensure that the deformation is controlled within a reasonable range, thus realizing the effective integration of the wall's shock absorption and energy dissipation functions and load-bearing functions.

[0031] In the above embodiments, reinforcing plates 13, stiffening plates 14, and flange extension plates 15 are provided on the I-beam. On the one hand, the reinforcing plates 13, stiffening plates 14, and flange extension plates 15 together form an I-shaped structure. The I-shaped structure transforms the force acting on the flange of the I-beam into an axial force acting on the middle of the web of the I-beam, reducing the stress on the flange position and increasing the strength of the vertical edge member 2. In the reinforcement project, it can better share the vertical load of the frame column and can simultaneously bear vertical and lateral loads. The member is lightweight and the manufacturing process is simple. On the other hand, since the thickness of the stiffness adjustment layer will vary according to actual needs, the added reinforcing plates 13, stiffening plates 14, and flange extension plates 15 can be adjusted with the thickness of the stiffness adjustment layer, which is highly adaptable and easy to construct.

[0032] The lightweight concrete 12 remains intact under frequent earthquakes but is damaged under designed earthquakes or even rare earthquakes. In this embodiment, the strength, thickness, and other parameters of the lightweight concrete 12 must ensure that it remains intact under frequent earthquakes but is damaged under designed earthquakes or even rare earthquakes.

[0033] Working principle: During implementation, the slider of connector 7 is slid to the middle of groove 6, and lightweight concrete 12 is poured into groove 6, which connects and fixes connector 7 and mounting block 5. Mounting block 5 is welded to one side of corrugated steel plate 1, and short reinforcing bars of connector 7 extend through long strip groove 3 to the other side of corrugated steel plate 1. V-shaped ribs 8 are welded and fixed to the free end of connector 7, and a steel reinforcement layer is laid. V-shaped ribs 8 provide stable support for the steel reinforcement layer. Ordinary concrete is poured on corrugated steel plate 1 to form main body 4. Corrugated steel plate 1 is welded to I-beams, and then reinforcing components are welded. The thickness of main body 4 can be adjusted according to on-site construction requirements, so that the stiffness of steel plate wall can be adjusted according to the thickness of stiffness adjustment layer. By changing the thickness of stiffness adjustment layer, its lateral stiffness and out-of-plane stiffness are changed, thereby meeting the lateral stiffness requirements and the elastic-plastic buckling resistance requirements of corrugated steel plate 1.

[0034] The mounting block 5 of this application has a groove 6 inside, forming a mold for pouring lightweight concrete 12. The lightweight concrete 12 can be poured in advance, and then the lightweight concrete 12, mounting block 5 and connector 7 are welded together onto the corrugated steel plate 1. The construction is convenient and quick, and the processing efficiency is improved. V-shaped ribs 8 and steel reinforcement layers are pre-embedded in the main body 4, so that the main body 4 forms a reinforced concrete layer. The overall stiffness of the stiffness adjustment layer is improved. When the corrugated steel plate 1 is constrained out of plane, the uniform transmission of the constraint effect can be ensured, and the constraint failure caused by local stress concentration can be avoided.

[0035] The working mechanism of the high-stiffness corrugated steel plate wall of this application is as follows: When the structure is subjected to a frequent earthquake, the lightweight concrete 12 does not fail, and the connector 7 is tightly connected to the mounting block 5. Therefore, the corrugated steel plate 1 and the stiffness adjustment layer are tightly connected and will not slip relative to each other. The stiffness adjustment layer and the corrugated steel plate 1 jointly resist lateral forces, resulting in high overall stiffness. When the structure is subjected to a design earthquake or even a rare earthquake, the lightweight concrete 12 fails, and horizontal relative displacement can occur between the stiffness adjustment layer and the corrugated steel plate 1. The connector 7 slips in the groove 6 of the mounting block 5, and the stiffness adjustment layer withdraws from resisting lateral forces. The lateral stiffness of the steel plate wall is only provided by the corrugated steel plate 1, and the stiffness adjustment layer only provides out-of-plane constraints for the corrugated steel plate 1. The out-of-plane stiffness of the stiffness adjustment layer ensures that the corrugated steel plate 1 does not buckle out of plane, thus ensuring the energy dissipation performance of the steel plate wall under seismic action. Based on the structure proposed in this application, by changing the thickness or in-plane and out-of-plane stiffness of stiffness-enhancing components such as concrete slabs, not only can the high stiffness of steel plate walls be achieved, but also the adjustable stiffness function of steel plate walls can be realized.

[0036] The stiffness adjustment layer of this application is mainly used to solve the stiffness requirements of steel plate walls. By using the stiffness adjustment layer, the required thickness of the corrugated steel plate 1 can be reduced, which solves the processing problem of the corrugated steel plate 1 and reduces the cost of the steel plate wall, thus facilitating the promotion and application of this new technology.

[0037] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
