Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a formwork-free earthquake-resistant and heat-insulating shear wall structure for buildings. Background Technology

[0002] In the field of building structures, shear walls, as core components resisting lateral forces, must simultaneously meet the requirements of load-bearing, seismic resistance, and thermal insulation and energy saving. The traditional model of separating shear wall construction from insulation layer installation has problems such as cumbersome procedures, large formwork losses, poor overall seismic resistance, and easy detachment of the insulation layer. It is difficult to adapt to the integrated requirements of modern buildings for "efficient construction, seismic safety, and long-term energy saving," becoming a key bottleneck restricting building quality and construction efficiency.

[0003] Traditional shear walls lack overall seismic resistance and struggle to cope with complex stress scenarios. The internal steel reinforcement of shear walls relies solely on concrete bonding to form a unified structure, resulting in limited lateral shear capacity. When subjected to horizontal seismic forces, the walls are prone to shear cracks and even brittle failure. Improving seismic performance requires increasing the amount of steel reinforcement or wall thickness, which not only increases construction costs (steel usage increases by 10%-15%) but also reduces usable building area. Furthermore, in traditional structures, the insulation layer is separated from the shear wall's load-bearing system and cannot participate in resisting lateral forces. During an earthquake, the detachment of the insulation layer can trigger secondary disasters, threatening human safety. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a formwork-free seismic-resistant and thermally insulated shear wall structure for buildings, which solves the technical problem of poor seismic performance of shear walls constructed with formwork in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a formwork-free, earthquake-resistant, thermally insulated shear wall structure for buildings, comprising: Insulation board; Connectors, wherein there are several connectors arranged on the insulation board; An inner mold is provided on the connector, and a casting space is formed between the insulation board and the inner mold. The connector is located within the casting space, and the inner mold is arranged parallel to the insulation board. A plurality of transverse reinforcing ribs are arranged in a manner that extends through the connector.

[0006] As a further technical solution, the connector has a plurality of spaced-apart V-shaped parts and a connecting portion for connecting two adjacent V-shaped parts. The connecting portion is perpendicular to the V-shaped parts and is also used to connect to the insulation board. The V-shaped parts are perpendicular to the insulation board and the inner mold.

[0007] As a further technical solution, the V-shaped component and the connecting part are an integral structure. The V-shaped component has a through space, and there is a flow space between two adjacent V-shaped components. The through space and the pouring space are used for the passage of concrete when pouring concrete into the pouring space.

[0008] As a further technical solution, two adjacent connecting parts on the same connector are located on both sides of the V-shaped member.

[0009] As a further technical solution, it also includes: A connecting piece is disposed on the connecting part, and the connecting part is connected to the insulation board through the connecting piece; Support plates, wherein there are several support plates arranged on the insulation board and located on the side of the insulation board away from the connector; A plurality of connecting fasteners are provided, each corresponding to one of the support pieces. Each connecting fastener has a connecting end and a pressing end. The pressing end is pressed onto the support piece, and the connecting end passes through the support piece and the insulation board and connects to the connecting piece.

[0010] As a further technical solution, the connecting piece is pressed onto the connecting portion, and the connecting fastener passes through the connecting portion and is connected to the connecting piece.

[0011] As a further technical solution, the connecting piece is welded to the connecting part, and the connecting part is pressed onto the connecting part.

[0012] As a further technical solution, it also includes: A right-angle fastener is provided at the end of the V-shaped part. The right-angle fastener has a first support plate and a second support plate. The first support plate and the second support plate are connected vertically and smoothly. The first support plate is provided at the end of the V-shaped part away from the insulation board, and the second support plate is away from the V-shaped part for connection with the inner mold.

[0013] As a further technical solution, it also includes: A vertical reinforcing rib is provided on the connector and is arranged parallel to the length direction of the connector.

[0014] As a further technical solution, the inner mold is a ribbed expanded metal mesh.

[0015] The beneficial effects of this utility model are as follows: In this invention, transverse reinforcing ribs penetrate the connectors, forming a "transversely load-bearing whole" from the dispersed connectors, preventing stress separation between the concrete, insulation board, and inner formwork within the pouring space. When the wall is subjected to horizontal seismic forces, the transverse reinforcing ribs can evenly transfer the force to the connectors, which then transmit it to the insulation board and inner formwork, forming a collaborative lateral force resisting system of "reinforcement-concrete-board," thus enhancing the horizontal shear bearing capacity of the wall. The concrete poured within the pouring space, together with the transverse reinforcing ribs and connectors, constitutes the wall's load-bearing framework, while the inner formwork serves as the inner protective layer, forming a three-in-one wall structure of "insulation layer + load-bearing layer + protective layer." This structure not only meets the thermal insulation and energy-saving requirements of residential buildings but also possesses the load-bearing and seismic resistance capabilities of a shear wall, making it suitable for multi-story and mid-to-high-rise residential buildings.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-6As shown, this invention illustrates a formwork-free seismic-resistant and thermally insulating shear wall structure for buildings in one embodiment. Several connectors 2 are fixed to the inner side of the insulation board 1 in a matrix arrangement. One end of the connector 2 is anchored to the insulation board 1, and the other end extends inward. The inner mold 3 is fixed to the extended end of the connector 2 by bolts. The inner mold 3 is set parallel to the insulation board 1, forming a closed pouring space 301 between them. The connector 2 is located entirely within the pouring space 301. Several transverse reinforcing ribs 4 are arranged at equal intervals along the height of the wall and penetrate the connectors 2 laterally, forming a rigid connection with the connectors 2 to jointly improve the overall seismic performance of the wall.

[0026] In this embodiment, the inner mold 3 forms a stable double-layer structure of "outer insulation board + inner mold" with the insulation board 1 through the connector 2. Unlike traditional shear wall construction, there is no need to build and dismantle wooden or steel formwork; concrete can be poured directly in the enclosed pouring space 301. Compared with traditional processes, this reduces the time spent on formwork procurement, installation, and dismantling. The width of the connector 2 matches the thickness of the pouring space 301, and their matrix arrangement forms a "support skeleton," which can effectively resist the lateral pressure during concrete pouring, prevent deformation of the inner mold 3 or the insulation board 1, and ensure that the thickness deviation of the wall after pouring meets the structural accuracy requirements.

[0027] The transverse reinforcing rib 4 penetrates the connector 2, making the dispersed connector 2 form a "transversely stressed whole", avoiding the separation of the concrete and the insulation board 1 and the inner formwork 3 in the pouring space 301. When the wall is subjected to horizontal seismic force, the transverse reinforcing rib 4 can evenly transfer the force to the connector 2, and then transfer it to the insulation board 1 and the inner formwork 3 through the connector 2, forming a "reinforcement-concrete-board" collaborative lateral force resisting system, thereby improving the horizontal shear bearing capacity of the wall.

[0028] One end of the connector 2 is anchored to the insulation board 1 by means of dovetail groove, expansion bolts, etc., and the other end is rigidly connected to the inner mold 3, ensuring that the concrete in the pouring space 301 is tightly bonded to the insulation board 1 and the inner mold 3, avoiding the phenomenon of "interlayer peeling" under earthquake action (traditional insulation layer and wall are prone to falling off due to earthquake), and improving the overall seismic stability of the wall.

[0029] Insulation board 1 serves as a permanent insulation layer on the exterior of the wall, directly integrated with the main structure without the need for post-installation, thus avoiding the risk of traditional external insulation layers falling off. Meanwhile, connector 2 uses materials with low thermal conductivity or is equipped with thermal insulation structures to reduce thermal bridging effects and meet the energy-saving requirements of buildings in extremely cold regions.

[0030] Concrete is poured into the pouring space 301, which together with the transverse reinforcing bars 4 and the connectors 2 form the load-bearing framework of the wall. The inner formwork 3 serves as the inner protective layer, forming a three-in-one wall structure of "insulation layer + load-bearing layer + protective layer". This structure not only meets the insulation and energy-saving requirements of residential buildings, but also has the load-bearing and seismic resistance of shear walls, making it suitable for multi-story and mid-rise residential buildings.

[0031] Furthermore, the connector 2 has a plurality of spaced V-shaped parts 201 and a connecting portion 202 for connecting two adjacent V-shaped parts 201. The connecting portion 202 is perpendicular to the V-shaped parts 201 and is also used to connect with the insulation board 1. The V-shaped parts 201 are perpendicular to the insulation board 1 and the inner mold 3.

[0032] In this embodiment, the connecting part 202 is vertically connected to the ends of two adjacent V-shaped parts 201 to form a continuous structure of "V-shaped unit + straight connection"; the side of the connecting part 202 away from the V-shaped part 201 is fixed to the inner side of the insulation board 1 by expansion bolts or adhesive to realize the rigid connection between the connecting part 2 and the insulation board 1; the axis of symmetry of the V-shaped part 201 is perpendicular to the surface of the insulation board 1 and the inner mold 3, and the two inclined sides of the V-shaped part 201 extend into the inner side of the casting space 301, and the transverse reinforcing rib 4 passes through the bend of the V-shaped part 201.

[0033] Compared to traditional straight bars, the V-shaped structure of V-shaped component 201 increases the bending section modulus by 2-3 times under the same cross-sectional dimensions. This better resists the lateral pressure of concrete in the pouring space 301 and prevents the inner mold 3 from sinking due to uneven stress. At the same time, the V-shaped opening faces the pouring space 301, and the concrete can completely wrap around V-shaped component 201 after pouring, forming an interlocking structure of "concrete-metal skeleton". This greatly improves the bonding strength between connector 2 and concrete, ensuring efficient transmission of seismic forces.

[0034] The connecting part 202 is vertically connected to the V-shaped part 201. On the one hand, it makes several V-shaped parts 201 form a unified force-bearing whole, avoiding the force deviation of a single V-shaped part 201. On the other hand, the fixing surface of the connecting part 202 and the insulation board 1 is a flat structure, and the contact area is 3-4 times larger than that of traditional point anchoring. This can disperse the local pressure of the connecting part 2 on the insulation board 1, prevent the insulation board 1 from cracking due to excessive local force, and at the same time ensure the positioning accuracy of the connecting part 2 on the insulation board 1.

[0035] The V-shaped components 201 are spaced apart, with their openings facing the inside of the pouring space, forming an "intermittent hollow skeleton" structure. Compared with densely arranged straight rod connectors, the flow resistance of concrete in the pouring space 301 is reduced, which can effectively avoid the concrete from being not compacted due to the dense connectors. At the same time, the bends of the V-shaped components 201 can guide the flow direction of concrete, ensuring that the transverse reinforcing bars 4 are fully wrapped by concrete, and improving the bond strength between the reinforcing bars and the concrete.

[0036] The fixing surface of the connecting part 202 and the insulation board 1 is only in partial contact (through point / line connection by bolts or adhesive) rather than being in large-area contact, which can reduce the heat transfer path between the metal connector and the insulation board 1; although the V-shaped part 201 is located in the pouring space 301, it is hollowed out and forms a composite structure of "metal skeleton + concrete filling" after being wrapped with concrete. Compared with all-metal connectors, the heat transfer coefficient of the thermal bridge part is reduced, further ensuring the overall thermal insulation performance of the wall.

[0037] When the inner mold 3 is fixed to the top of the V-shaped part 201 by bolts, the V-shaped part 201 is perpendicular to the inner mold 3 plate surface, which can ensure the parallelism between the inner mold 3 and the insulation board 1 and avoid uneven thickness of the pouring space 301. At the same time, the interval of the V-shaped part 201 can serve as the "positioning reference" for the installation of the inner mold 3, reducing the on-site leveling process.

[0038] The transverse reinforcing rib 4 passes through the bend of the V-shaped component 201, forming an interwoven structure of "transverse rib - V-shaped skeleton". Under seismic action, the horizontal force can be quickly transferred to the insulation board 1 and the inner mold 3 through the V-shaped component 201, avoiding local stress concentration. At the same time, the V-shaped structure has a strong elastic deformation capacity, which can absorb some seismic energy and improve the ductility of the wall.

[0039] The V-shaped part 201 and the connecting part 201 are an integrated continuous structure without splicing gaps, which can avoid the corrosion caused by cement slurry seeping into the gaps during concrete pouring, ensure the long-term stable operation of the connecting part 2, and extend the service life of the wall.

[0040] Furthermore, the V-shaped component 201 and the connecting part 202 are an integral structure. The V-shaped component 201 has a through space 203, and there is a flow space 204 between two adjacent V-shaped components 201. The through space 203 and the pouring space 301 are used for the passage of concrete when pouring concrete into the pouring space 301.

[0041] In this embodiment, a through space 203 is formed between the two inclined sides of the V-shaped member 201; after two adjacent V-shaped members 201 are connected by the connecting part 202, a flow space 204 is formed between them; the through space 203 and the flow space 204 together constitute a concrete flow channel, which is completely connected to the pouring space 301 and is used to quickly fill the pouring space 301 when pouring concrete to avoid pouring dead corners.

[0042] When pouring in layers, the through space 203 and the flow space 204 can balance the pressure of each layer of concrete and prevent the lower layer of concrete from being squeezed out. When pouring at multiple points, the flow space 204 can make the concrete at different points quickly blend together, reduce interface delamination, and improve the overall strength of the wall.

[0043] The V-shaped part 201 and the connecting part 202 are integrally stamped, avoiding the "weak points" of welding or bolting. It can withstand greater lateral pressure during concrete pouring and will not fail due to splice breakage under the action of seismic horizontal force, thus improving the seismic reliability of the wall.

[0044] When the bend of the V-shaped member 201 is penetrated by the transverse reinforcing bar 4, the through space 203 allows the concrete to fully wrap the surface of the reinforcing bar, avoiding "void" between the reinforcing bar and the connector, ensuring that the seismic force can be efficiently transmitted through the path of reinforcing bar-concrete-connector, and improving the shear bearing capacity of the wall.

[0045] The connecting part 202 and the fixing surface of the insulation board 1 are a flat structure with uniform contact pressure and no splicing protrusions, which can prevent the insulation board 1 from cracking due to local stress concentration. At the same time, the flow channel guides the concrete to fill quickly, reducing the time of the concrete pushing the insulation board 1 laterally and reducing the risk of deformation of the insulation board 1.

[0046] Furthermore, two adjacent connecting portions 202 on the same connector 2 are located on both sides of the V-shaped member 201.

[0047] In this embodiment, the design of having adjacent connecting portions 202 on both sides of the V-shaped component 201 on the same connector 2 is a further optimization of the "staggered skeleton" structure. This layout not only solves the problems of force concentration and space congestion in the traditional co-linear layout, but also ensures the perpendicularity of the V-shaped component 201 to the insulation board 1 by fixing it on both sides, achieving multiple goals of "more stable force, smoother pouring, and more convenient construction", and ensuring the stability of the thickness and shape of the pouring space 301 during the pouring process.

[0048] Furthermore, it also includes a connecting piece 5, which is disposed on the connecting part 202. The connecting part 202 is connected to the insulation board 1 through the connecting piece 5. There are several supporting pieces 6, which are arranged on the insulation board 1 and located on the side of the insulation board 1 away from the connecting piece 2. There are several connecting fasteners 7, which are arranged one-to-one with the supporting pieces 6. The connecting fasteners 7 have a connecting end 701 and a pressing end 702. The pressing end 702 is pressed on the supporting piece 6, and the connecting end 701 passes through the supporting piece 6 and the insulation board 1 and is connected to the connecting piece 5.

[0049] In this embodiment, the connecting fastener 7 is clamped from both sides of the insulation board 1 by the support plate 6 and the connecting plate 5. Compared with the traditional "single-sided anchoring" (only the inner connecting part is fixed), the pull-out bearing capacity is improved, which can effectively resist the lateral tension during concrete pouring and the interlayer shear force under earthquake action, and avoid the phenomenon of "detachment" between the connecting fastener 2 and the insulation board 1, thus ensuring the integrity of the overall wall structure.

[0050] The area of ​​the support plate 6 and the connecting plate 5 is 5-8 times larger than the area of ​​the bolt head of the connecting fastener 7. This can evenly distribute the clamping force of the bolt to the surface of the insulation board 1, avoid the direct pressing of the bolt causing local dents or cracks in the insulation board 1, and prevent the bolt from "embedding" into the insulation board 1 under long-term stress, thus ensuring the long-term stability of the fastening force of the connecting fastener 7.

[0051] Insulation board 1 is prone to warping and deformation during transportation, construction or temperature changes. The bidirectional clamping of support piece 6 and connecting piece 5 can form "multi-point constraint" on insulation board 1, ensuring that insulation board 1 always remains parallel to connecting piece 2 and inner mold 3, avoiding uneven thickness of pouring space 301 due to insulation board warping, which would affect the quality of concrete pouring.

[0052] The support plate 6 is not only the load-bearing carrier of the connecting fastener 7, but also serves as a support beam on the outside of the insulation board 1. When the wall is subjected to lateral wind pressure or seismic force, the support plate 6 can transfer the force to the adjacent connecting fastener 7, and then to the connecting piece 5 to the connecting piece 2 and the transverse reinforcing bar 4, forming a lateral force system of "outer support-connecting piece-reinforcing bar". This improves the lateral stiffness of the wall and reduces the bending deformation of the wall under load.

[0053] The support piece 6 and the connecting piece 5 correspond one-to-one, and both have pre-set positioning holes. During construction, the connecting fastener 7 can be quickly installed simply by aligning the positioning holes, eliminating the need for on-site measurement and drilling, thus improving installation efficiency. In addition, the connecting fastener 7 uses a threaded connection, which can adjust the tightening depth according to the thickness of the insulation board 1, making it suitable for insulation boards of different thicknesses (50-100mm) and highly versatile.

[0054] Furthermore, the connecting piece 5 is pressed onto the connecting part 202, and the connecting fastener 7 passes through the connecting part 202 and connects with the connecting piece 5.

[0055] In this embodiment, the connecting fastener 7 passes through the support plate 6, the insulation board 1, and the connecting part 202 and is locked with the connecting plate 5. The axial pressure of the bolts tightly presses the four-layer structure together, eliminating the gaps that may exist in the traditional "welding of connecting plate and connecting part". This changes the connection between the connecting piece 2 and the insulation board 1 from "partial fixing" to "overall rigid anchoring", further improving the pull-out bearing capacity compared to the welding method.

[0056] Furthermore, the connecting piece 5 is welded to the connecting part 202, and the connecting part 202 is pressed onto the connecting part 202.

[0057] In this embodiment, welding makes the connecting piece 5 and the connecting part 202 form an inseparable whole, avoiding the risk of loosening of traditional single bolt connection under long-term vibration (such as earthquake, wind pressure); the bolt provides anchoring force perpendicular to the insulation board. The combination of the two improves the pull-out bearing capacity and shear bearing capacity of the connection part, and can withstand the large lateral pressure of high-strength concrete pouring.

[0058] The connecting piece 5 presses against the connecting part 202, and the gap-free connection can prevent rainwater and moisture from seeping in and causing internal corrosion. At the same time, the mating surface can evenly transmit the bolt tightening force, prevent the connecting part 202 from bending and deforming due to local stress concentration, and ensure that the connecting piece 2 always maintains a perpendicular posture to the insulation board 1 and the inner mold 3, thus ensuring that the thickness of the pouring space 301 is uniform.

[0059] Furthermore, it also includes a right-angle fastener 8, which is disposed at the end of the V-shaped part 201. The right-angle fastener 8 has a first support plate 801 and a second support plate 802. The first support plate 801 and the second support plate 802 are perpendicularly and smoothly connected. The first support plate 801 is disposed at the end of the V-shaped part 201 away from the insulation plate 1, and the second support plate 802 is away from the V-shaped part 201 and is used to connect with the inner mold 3.

[0060] In this embodiment, the right-angle fastener 8 converts the longitudinal support force of the V-shaped part 201 into the opposing lateral fixing force through two vertical support plates, avoiding the "single-point force offset" that occurs in the traditional "V-shaped part directly connected to the inner mold". When the concrete pouring generates lateral pressure, the force can be evenly transmitted to the inner mold 3 through the second support plate 802 to prevent the inner mold from bulging or cracking.

[0061] Each V-shaped component 201 is provided with a right-angle fixing component 8 at its end, and the second support plate 802 is fully fitted with the inner mold 3, so that the dispersed V-shaped components 201 form an "integrated load-bearing frame" through the inner mold 3. The in-plane stiffness of the wall is improved, which can better resist the bending of the wall caused by earthquake horizontal force or wind pressure, and avoid the "separation gap" between the connector and the inner mold.

[0062] The second support plate 802 of the right-angle fastener 8 has a flat surface and is parallel to the insulation board 1. It can be used as a "reference surface" for the installation of the inner mold 3. During construction, the inner mold 3 only needs to be attached to the second support plate 802 for fixation. There is no need to repeatedly level it, which ensures that the pouring space 301 between the inner mold 3 and the insulation board 1 has a uniform thickness.

[0063] Furthermore, it also includes a vertical reinforcing rib 9, which is disposed on the connector 2 and is arranged parallel to the length direction of the connector 2.

[0064] In this embodiment, the vertical reinforcing ribs 9 are continuously arranged along the height of the wall, which can directly bear the vertical load of the building (such as the self-weight of the floor slab and live load), and evenly transfer the load to the foundation, avoiding local crushing caused by the concrete in the pouring space 301 being subjected to force alone, and are suitable for the vertical bearing requirements of mid-to-high-rise residential buildings with 7 floors or more.

[0065] After forming a "two-way steel mesh" with the transverse reinforcing bars 4, the in-plane shear capacity of the wall is improved, which can effectively resist the horizontal shear force under earthquake action; at the same time, the steel mesh can restrain the deformation of concrete, improve the ductility of the wall, and avoid brittle failure of the wall during earthquakes.

[0066] The vertical reinforcing bar 9 is fixed to the V-shaped part 201 and the connecting part 202 of the connector 2, so that the dispersed connectors 2 are connected by steel bars to form a "vertical support skeleton", which prevents the connectors 2 from shifting laterally under concrete pouring or seismic action; at the same time, the connectors 2 can serve as temporary support for the vertical reinforcing bar 9 to ensure the accurate installation position of the steel bars.

[0067] Furthermore, the inner mold 3 is a reinforced expanded mesh.

[0068] In this embodiment, the reinforced expanded metal mesh can be permanently bonded to the concrete in the pouring space 301. After the concrete hardens, the mesh is embedded in the concrete surface to form a composite structure of "reinforced steel-concrete-mesh", and the mesh surface does not require secondary plastering.

[0069] The diamond-shaped mesh has a "two-way permeability" characteristic. During concrete pouring, excess air can be discharged through the mesh, avoiding air bubbles or voids. At the same time, the mesh allows the concrete surface to penetrate and form "interlocking protrusions", which increases the bonding strength between the inner mold 3 and the concrete to 3-4 times that of traditional formwork, ensuring long-term structural stability.

[0070] The longitudinal reinforcing bars of the reinforced expanded metal mesh, together with the vertical reinforcing bars 9 and the transverse reinforcing bars 4 of the wall, form a "three-dimensional steel reinforcement system" that can share some of the horizontal and vertical loads. When facing the lateral pressure of concrete pouring, the overall stiffness of the mesh is more than twice that of the fiber cement board, which avoids the inner mold bulging and uneven thickness of the pouring space 301.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
