Description

Technical Field

[0001] The present application relates to the technical field of housing construction, and in particular to a large-span flat plate-shear wall structural system using a fully industrialized production method. Background Art

[0002] People are paying more and more attention to the efficiency of using the interior space of buildings and the comfort of using the building space. The structural form of modern buildings is mostly frame-shear structure, which is a structural system that arranges a certain number of shear walls in the frame structure and combines the frame and shear walls together.

[0003] The frame-shear structure will have multiple shear walls inside the house. The shear wall is a fixed and immutable wall that needs to bear weight. It limits the internal space of the house, making the internal space non-variable, and has a single design function. It also imposes many restrictions on the decoration layout and cannot meet the needs of users. In addition, the shear wall structure has strict requirements on the spacing between walls. Due to the restrictions of the shear wall structure on the indoor space, the room spans of high-rise residential products on the market are basically within 3-5 meters. The existing residential structure is difficult to meet the needs of users for diversified space layout. Summary of the invention

[0004] In order to reduce the number of indoor shear walls while ensuring stable load-bearing and to meet the needs of variable indoor space, the present application provides a large-span flat plate-shear wall structural system using a fully industrialized production method.

[0005] The present application provides a large-span flat plate-shear wall structural system using a fully industrialized production method, which adopts the following technical solutions: A large-span flat plate-shear wall structural system using a fully industrialized production method includes shear walls and floor slabs. The shear walls are arranged at the periphery of the room, the elevator room of the building, and the partition wall. The floor slab is provided with two layers and is respectively located on the upper and lower sides of the shear wall. The floor slab array is arranged with multiple adjacent floor slabs on the same layer abutting against each other.

[0006] By adopting the above technical solution, shear walls are arranged around the room, elevator room and partition walls, which reduces the number of indoor shear walls, realizes large-span space design, and improves the utilization and flexibility of indoor space. Residential space can be quickly adjusted as needed, thus better meeting users' needs for diverse spatial layouts.

[0007] Optionally, a transverse pipe is embedded in the floor slab along its length direction, and both ends of the transverse pipe are closed; a vertical pipe is embedded in the shear wall along its height direction, and both ends of the vertical pipe are open; connecting components are provided between two adjacent floor slabs and between a floor slab and a shear wall, and the connecting components are used to connect the transverse pipes in two adjacent floor slabs or the transverse pipes in a floor slab with the vertical pipes in the shear wall; a fan is provided on the vertical pipe in one of the shear walls.

[0008] By adopting the above technical scheme, the vertical pipes in the shear wall and the horizontal pipes in the upper and lower floor slabs are connected through the connecting components, so that the vertical pipes and the horizontal pipes can jointly form a gas flow loop, and under the action of the fan, the air in the loop can circulate; in hot weather, when the shear wall close to the outdoor side is directly exposed to the sun, the shear wall will heat up rapidly, so that the air in the vertical pipes in the shear wall is heated, and the fan can circulate the hot air in the loop, avoiding heat accumulation and causing the shear wall exposed to direct sunlight to heat up rapidly, so that the temperature of each part of the shear wall and the floor slab is more consistent, thereby reducing the impact of direct sunlight on the shear wall, which helps to extend the service life.

[0009] Optionally, the vertical pipes are provided in plurality and are evenly spaced, and each of the vertical pipes is connected to the horizontal pipe via a connecting assembly.

[0010] By adopting the above technical solution, multiple vertical pipes are evenly spaced and arranged, which helps to improve the uniformity of air circulation and can better transfer the heat in the shear wall to the air in the vertical pipes, thereby accelerating the heat dissipation of the shear wall.

[0011] Optionally, a plurality of transverse pipes are provided and arranged at intervals, and two adjacent transverse pipes in the same floor slab are connected.

[0012] By adopting the above technical solution, the setting of the hollow horizontal pipe can, on the one hand, occupy a part of the space inside the floor slab, reduce the amount of concrete poured, thereby reducing the deadweight and better adapting to the installation requirements of large spans; on the other hand, it can make the hot air flowing out of the vertical pipe in the shear wall more fully contact with the floor slab, so that the heat in the hot air can be transferred to the floor slab more, thereby accelerating the heat dissipation of the hot air.

[0013] Optionally, a connecting pipe is embedded in the floor slab, and the connecting pipe is arranged between two adjacent transverse pipes. Both ends of the connecting pipe are respectively connected to the two transverse pipes, and the connecting pipes at both ends of each transverse pipe are staggered.

[0014] By adopting the above technical solution, the connecting pipes embedded in the floor slab can effectively enhance the connection strength and stability between the transverse pipes. Since the connecting pipes occupy a certain space inside the floor slab, the amount of concrete pouring is further reduced, thereby reducing the deadweight of the floor slab. In addition, the staggered connecting pipes allow the hot air to contact the floor slab more fully, thereby further accelerating the discharge of heat in the hot air.

[0015] Optionally, the connecting assembly includes an embedded tube and a connecting tube, the embedded tube is buried in the floor slab, one end of the embedded tube is connected to the transverse pipe, one end of the connecting tube is located in the embedded tube and is threadedly connected to the embedded tube, and the other end of the connecting tube is located outside the floor slab and is used to be connected to the transverse pipe in the adjacent floor slab or the vertical pipe in the shear wall.

[0016] By adopting the above technical solution, a quick connection between the horizontal pipes and the vertical pipes is achieved, the assembly construction efficiency is improved, and the sealing and stability of the system can be enhanced.

[0017] Optionally, a flexible pad is provided on the outer wall of one end of the connecting tube located outside the floor slab.

[0018] By adopting the above technical solution, the sealing of the connection parts can be effectively improved, and air leakage caused by poor sealing of the connection parts can be reduced, thereby improving the use effect of the entire system.

[0019] Optionally, a heat conducting member is fixedly provided on the outer wall of the vertical pipe, a plurality of the heat conducting members are provided and are arranged at intervals along the length direction of the vertical pipe, and the heat conducting member is embedded in the interior of the shear wall.

[0020] By adopting the above technical solution, on the one hand, in the shear wall exposed to direct sunlight, the heat conductor can transfer more heat in the shear wall to the air in the vertical pipe, thereby accelerating the heat dissipation of the shear wall; on the other hand, in the shear wall indoors on the side away from the sunlight, the heat conductor can dissipate more heat in the hot air in the vertical pipe to the outside, thereby further enhancing the heat dissipation effect.

[0021] Optionally, a grille is provided at the bottom of the floor.

[0022] By adopting the above technical solution, the grille and the floor slab are assembled and installed in an integrated manner in the factory to form a composite floor slab, which can improve the overall stiffness of the composite floor slab during the on-site construction phase and reduce the support workload during the floor slab construction phase; in addition, since the grille and the floor slab are offset from each other, part of the heat in the floor slab can be transferred to the grille, and the large surface of the grille helps to further accelerate the dissipation of heat.

[0023] Optionally, a mounting hole is provided on the grille, and a wiring tube for accommodating pipelines is passed through the mounting hole.

[0024] By adopting the above technical solution, the layout and maintenance of pipelines are facilitated, thereby improving space utilization.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By combining the outer shear walls with the upper and lower large-span floor slabs, the number of indoor shear walls can be reduced, thereby providing greater spatial flexibility and variability to meet the needs of modern families for variable spaces.

[0026] 2. The setting of the grille increases the rigidity of the floor slab, thus helping to reduce the support workload during the floor slab construction phase and making it more convenient.

[0027] 3. The internal horizontal and vertical pipes can form a circulation loop together. The heat generated by the shear wall exposed to direct sunlight can be transferred to the air inside the loop. Under the action of the fan, the hot air in the loop can circulate. The heat in the hot air will continue to dissipate outward when passing through other parts, thereby avoiding heat concentration that causes the shear wall to heat up sharply, which helps to extend the service life of the wall.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The present application embodiment discloses a large-span flat plate-shear wall structure system using a fully industrialized production method. Figure 1 and Figure 2 The large-span flat plate-shear wall structure system using a fully industrialized production method includes a shear wall 1 and a floor slab 2. The shear wall 1 is a hollow composite shear wall, which includes a prefabricated wall panel 11, a steel skeleton 12 and a first concrete layer 13; the prefabricated wall panel 11 is a prefabricated concrete panel, two prefabricated wall panels 11 are arranged in parallel and spaced apart, the steel skeleton 12 is fixedly arranged between the two prefabricated wall panels 11, the first concrete layer 13 is arranged between the two prefabricated wall panels 11, and the steel skeleton 12 is buried inside the first concrete layer 13. During molding, after the connection between the prefabricated wall panel 11 and the steel skeleton 12 is completed, concrete is poured between the two prefabricated wall panels 11, and a hollow composite shear wall can be formed after the concrete solidifies and the curing is completed.

[0032] Reference Figure 3 The floor 2 is a prestressed hollow composite slab, and the floor 2 includes a precast bottom plate 21, a steel tube truss 22, a steel mesh and a second concrete layer 23. The precast bottom plate 21 is a precast concrete slab. One end of the steel tube truss 22 is buried in the precast bottom plate 21, and a plurality of steel tube trusses 22 are arranged evenly spaced. The steel mesh is arranged on the side of the steel tube truss 22 away from the precast bottom plate 21, and the steel mesh includes a plurality of steel bars that are staggered horizontally and vertically and tied and fixed to each other. The second concrete layer 23 is arranged above the precast bottom plate 21, and the steel tube truss 22 and the steel mesh are buried in the second concrete layer 23. When the floor 2 is formed, the precast bottom plate 21 with the steel tube truss 22 buried is first cast; then the steel mesh is tied on the top of the steel tube truss 22, and then the second concrete layer 23 is cast on the top surface of the precast bottom plate 21; after the concrete solidifies and the curing is completed, the forming of the floor 2 is completed.

[0033] Furthermore, a transverse pipe 3 is arranged between two adjacent steel pipe trusses 22 in the floor slab 2, and the transverse pipe 3 is arranged along the length direction of the prefabricated base plate 21; both ends of the transverse pipe 3 are closed and the inside is hollow, so that the poured concrete cannot enter the transverse pipe 3, thereby reducing the pouring amount of concrete, helping to reduce the deadweight of the floor slab 2, thereby better adapting to large-span installation scenarios.

[0034] Shear walls 1 are arranged at the periphery of the room, the elevator room and the partition wall. Floor slabs 2 are arranged in two layers, which are fixed on the top and bottom walls of the shear wall 1 respectively. There are multiple floor slabs 2 on each floor, and multiple floor slabs 2 are abutted against each other; two adjacent floor slabs 2 are fixedly connected. Since the shear walls 1 are arranged at the periphery of the room, they are all loaded by the exterior walls, and there are no columns or beams in the room, thus providing greater spatial flexibility and variability. Both the shear walls 1 and floor slabs 2 can be prefabricated in the factory, so the degree of industrialization is higher, which can greatly reduce the workload of the on-site construction process.

[0035] Reference Figure 3 and Figure 4 Furthermore, a grille 9 is fixedly connected to the bottom wall of the floor 2. A mounting hole 91 is provided on the side wall of the grille 9, and a wiring tube 92 for accommodating pipelines can be passed through the mounting hole 91, thereby facilitating the arrangement of fresh air ducts, air conditioning ducts, water pipes and electric pipes. A decorative panel 10 is also fixedly provided at the bottom of the grille 9.

[0036] Reference Figure 3 A vertical pipe 4 is also buried in the shear wall 1, and the vertical pipe 4 is arranged along the height direction of the shear wall 1; there are multiple vertical pipes 4 and they are evenly spaced and arranged along the width direction of the shear wall 1, and both ends of the vertical pipes 4 are open. A connecting assembly 5 is provided between the transverse pipes 3 in two adjacent floor slabs 2 and between the ends of the vertical pipes 4 and the transverse pipes 3 in the upper and lower floor slabs 2. The connecting assembly 5 is used to connect the transverse pipes 3 in the two adjacent floor slabs 2 or the transverse pipes 3 in the floor slab 2 with the vertical pipe 4 in the shear wall 1, so that the transverse pipes 3 and the vertical pipes 4 can together form a circulation loop for air circulation.

[0037] Reference Figure 5 and Figure 6 , the connection assembly 5 includes an embedded tube and a connecting tube. The embedded tube includes a first cylinder 51, a second cylinder 52 and a third cylinder 53, and the first cylinder 51, the second cylinder 52 and the third cylinder 53 are all cylinders, and the first cylinder 51, the second cylinder 52 and the third cylinder 53 are all buried in the floor 2. The axis of the first cylinder 51 and the second cylinder 52 is horizontal; the first cylinder 51 and the second cylinder 52 are provided in multiple numbers, and are evenly spaced and arranged along the length direction of the transverse pipe 3; the first cylinder 51 and the second cylinder 52 are respectively fixedly connected to the side of the transverse pipe 3 on both sides of the same floor 2 that is away from each other. The first cylinder 51 and the second cylinder 52 are both connected to the inside of the corresponding transverse pipe 3. The number of the first cylinder 51 and the second cylinder 52 is the same, and each first cylinder 51 is used to correspond to the second cylinder 52 in the adjacent floor 2. The inner wall of the first cylinder 51 is provided with an internal thread, and the inner wall of the second cylinder 52 is smoothly set.

[0038] The connecting tube includes a first connecting tube 54 and a second connecting tube 55. An external thread matching the internal thread on the first cylinder 51 is provided on the outer wall at one end of the first connecting tube 54, so that one end of the first connecting tube 54 can be threadedly connected to the first cylinder 51, and the first connecting tube 54 can be fixedly connected to the floor 2. Then, the adjacent floor 2 is slid, so that the end of the first connecting tube 54 away from the external thread can be inserted into the second cylinder 52 on the adjacent floor 2, so that the transverse pipes 3 in the two adjacent floor slabs 2 can be connected through the first cylinder 51, the first connecting tube 54 and the second cylinder 52.

[0039] Reference Figure 3 and Figure 7 Furthermore, a connecting pipe 6 is provided between two adjacent transverse pipes 3, the axis of the connecting pipe 6 is perpendicular to the axis of the transverse pipe 3, and both ends of the connecting pipe 6 are respectively connected to the transverse pipes 3 on both sides. There are multiple connecting pipes 6, and multiple connecting pipes 6 are evenly spaced along the axis direction of the transverse pipe 3; the connecting pipes 6 at both ends of each transverse pipe 3 are staggered. Therefore, the arrangement of the connecting pipes 6 can make multiple transverse pipes 3 in each floor slab 2 communicate with each other.

[0040] The axis of the third cylinder 53 is vertically arranged. The third cylinder 53 is fixedly connected to the transverse pipe 3 in the floor slab 2 at the outermost edge. The third cylinder 53 is provided with multiple and evenly spaced along the length direction of the transverse pipe 3. The third cylinder 53 is connected to the interior of the transverse pipe 3. An internal thread is provided on the inner wall of the third cylinder 53. An external thread matching the internal thread on the third cylinder 53 is provided on the outer wall of one end of the second connecting cylinder 55. The end of the second connecting cylinder 55 is threadedly connected to the third cylinder 53, so that the second connecting cylinder 55 is fixedly connected to the floor slab 2. The end of the second connecting cylinder 55 away from the external thread is inserted into the vertical pipe 4 in the shear wall 1, so that the transverse pipe 3 in the floor slab 2 and the vertical pipe 4 in the shear wall 1 can be connected through the third cylinder 53 and the second connecting cylinder 55.

[0041] Therefore, the setting of the connecting component 5 can interconnect the horizontal pipe 3 in the floor 2 and the vertical pipe 4 in the shear wall 1, so that the horizontal pipe 3 and the vertical pipe 4 can form a closed circulation loop together. A fan is fixedly installed in the vertical pipe 4 in the shear wall 1 close to the indoor side, so that the air in the circulation loop can circulate after the fan is turned on. In hot weather, under the direct sunlight, the air in the vertical pipe 4 in the shear wall 1 close to the outdoor side will heat up, and then the action of the fan can make this part of the hot air circulate, thereby avoiding the accumulation of heat in the shear wall 1, helping to enhance the heat dissipation of the shear wall 1, and thus ensuring the service life of the shear wall 1.

[0042] In other embodiments, the fan may also be arranged outside the shear wall 1, and the fan and the vertical pipe 4 are connected via a pre-buried pipe; a part of the pre-buried pipe is buried in the shear wall 1 for connecting with the vertical pipe 4; another part of the pre-buried pipe is located outside the shear wall 1 for connecting with the fan, so as to facilitate the fan to send air into the vertical pipe 4 and accelerate the air flow. The number of fans can be set to one or more, and can be set as needed.

[0043] Reference Figure 6 Furthermore, a flexible pad 7 is fixedly bonded to the outer wall of the first connecting tube 54 and the second connecting tube 55 away from the external thread. The flexible pad 7 is made of rubber. The flexible pad 7 on the first connecting tube 54 abuts against the inner wall of the second cylinder 52, and the flexible pad 7 on the second connecting tube 55 abuts against the inner wall of the vertical pipe 4, thereby helping to enhance the sealing effect of the connection.

[0044] Reference Figure 3 The outer wall of the vertical pipe 4 is also fixedly connected with a heat conductor 8, and a plurality of heat conductors 8 are provided and are evenly spaced and arranged along the length direction of the vertical pipe 4. The heat conductor 8 is buried inside the shear wall 1, and the heat conductor 8 includes a mounting ring 81 and a connecting piece 82. The mounting ring 81 is sleeved on the outer wall of the vertical pipe 4, and the connecting piece 82 is fixedly connected to the outer wall of the mounting ring 81. A plurality of connecting pieces 82 are provided and arranged in a circumferential array. The heat conductor 8 is made of metal copper, so the heat conductor 8 can accelerate the transfer of heat and help enhance the heat dissipation of the shear wall 1.

[0045] The implementation principle of a large-span flat plate-shear wall structure system using a fully industrialized production method in the embodiment of the present application is as follows: after the shear wall 1 and the floor slab 2 are installed, multiple transverse pipes 3 in the same floor slab 2 are connected through the connecting pipe 6; the transverse pipes 3 in two adjacent floor slabs 2 are connected through the first cylinder 51, the first connecting cylinder 54 and the second cylinder 52; the transverse pipes 3 in the floor slab 2 and the vertical pipes 4 in the shear wall 1 are connected through the third cylinder 53 and the second connecting cylinder 55. Therefore, the transverse pipes 3 and the vertical pipes 4 can form a closed circulation loop. After the fan is started, the hot air in the shear wall 1 close to the outdoor side can circulate. During the flow of the hot air, part of the heat is dissipated to the outside, thereby avoiding the heat accumulation in the shear wall 1 close to the outdoor side, avoiding the excessive temperature of the shear wall 1, and helping to ensure the service life of the shear wall 1.

[0046] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
