Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to prefabricated shear wall structures. Background Technology

[0002] Prefabricated shear wall structures have become an important development direction for building industrialization due to their advantages such as high construction efficiency and high degree of prefabrication. In traditional technology, tie bolt connection systems are often used to connect and fix the wall panels on both sides (such as the inner wall panel and the outer wall panel): bolts pass through the wall panels or formwork on both sides, and nuts are tightened to generate tension, resisting the lateral pressure during concrete pouring and ensuring the stability of the wall panel position.

[0003] For example, the prefabricated double-steel-plate shear wall with patent application number 201820371677.X includes a first steel plate and a second steel plate, which are fixed together by bolts. Concrete is then poured inside the two steel plates to form the prefabricated double-steel-plate shear wall. This design first requires through holes to be made in the steel plates, which disrupts the continuity of the steel plates and leads to a decrease in the shear and compressive strength of the steel plates themselves. Moreover, this method of transmitting tensile force through tie bolts is a single-point stress, which makes it difficult to evenly distribute the lateral pressure of the concrete. When the load is large, the bolts are prone to deformation and the steel plates are prone to cracking. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a prefabricated shear wall structure.

[0005] The technical solution to the technical problem solved by this utility model is as follows:

[0006] This utility model proposes a prefabricated shear wall structure, comprising several interconnected shear wall units. Each shear wall unit includes spaced-apart inner wall panels and outer wall panels. Several sets of connecting plates are fixed to the inner walls of both the inner and outer wall panels. The connecting plates on both sides are staggered, and each connecting plate has a partition plate at its end, forming a T-shaped structure. Adjacent partition plates abut against each other, forming a closed intermediate tie plate surface. A casting cavity is enclosed between adjacent connecting plates and the intermediate partition plate. Several sets of first perforations are vertically arrayed on the connecting plates, and several sets of first horizontal reinforcements are also included. The first horizontal reinforcements transversely penetrate the corresponding first perforations and extend to the outside of the connecting plate. Tie members are connected between the first horizontal reinforcements on both sides, clamping and positioning the intermediate partition plate through the first horizontal reinforcements. Concrete is poured between the two inner and outer wall panels to form the shear wall unit.

[0007] Preferably, the end of the connecting plate is connected to an insert plate, the insert plate is arranged perpendicularly to the connecting plate, and the inner side of the partition plate is provided with a slot adapted to the insert plate and is inserted into the insert plate.

[0008] Preferably, the first perforation is formed by two semi-circular arc-shaped hole ends and two parallel straight-edged hole walls, with the two semi-circular arc-shaped hole ends located at the two ends of the parallel straight-edged hole walls, and the whole is long and narrow with arc-shaped transitions at both ends.

[0009] Preferably, each of the two first transverse ribs has a corresponding through hole; the tie member includes a bolt, which passes through the through hole on the two first transverse ribs and is threadedly connected to a nut. Tightening the nut and the bolt thread connection achieves clamping of the two first transverse ribs.

[0010] Preferably, a steel cage is connected between the two shear wall units, and an outer formwork is built outside the steel cage. Concrete is poured between the two outer formworks to fix the shear wall units on both sides, forming a prefabricated shear wall structure.

[0011] Preferably, the connecting plate has a number of sets of second through holes arranged vertically, and also includes a number of sets of second horizontal bars. The second horizontal bars pass through the corresponding second through holes and extend to the outside of the connecting plate. At least one end of the second horizontal bar is detachably connected to a hook, and the hook is hooked onto the steel cage.

[0012] Preferably, the second perforation and the first perforation are arranged alternately at vertical intervals, and the second perforation is located outside the first perforation. The hook fastener of the second horizontal bar is hooked to the vertical bar of the steel cage.

[0013] Preferably, the fastening element includes a threaded sleeve fixed to the end of the second transverse rib, the threaded sleeve having a threaded post internally connected, and the other end of the threaded post having a hook rotatably connected.

[0014] Preferably, a limiting groove is formed inside the threaded post, and a rotatable limiting post is provided inside the limiting groove. A limiting ring is connected to the top of the limiting groove to prevent the limiting post from falling out. The limiting post is connected to a connecting post, and the connecting post passes through the inside of the limiting ring and is connected to the hook.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] 1. In this utility model, staggered connecting plates and partitions connected to the connecting plates work together to form a closed intermediate tie plate surface. When pouring concrete, the contact surface of the partitions can transmit stress. Compared with the traditional bolt connection, the point constraint is upgraded to the surface constraint, which can effectively limit the displacement of the inner wall panel and the outer wall panel and improve the overall stability. Moreover, this design does not require drilling holes in the wall panel, which avoids damaging the structural strength of the wall panel and improves the overall aesthetics, achieving a dual optimization of function and appearance.

[0017] 2. In this utility model, the first transverse rib penetrating through the connecting plate constitutes a transverse tie system, which works in conjunction with the tie rod; compared with traditional tie bolts, it can distribute the force, strengthen the internal shear resistance, and make the structural deformation more controllable when bearing loads such as concrete lateral pressure.

[0018] 3. In this utility model, a second horizontal reinforcing bar is provided through the connecting plate, and a hook is provided at the end of the second horizontal reinforcing bar to tie and fix the reinforcing cage. Through the design of the hook, the reinforcing cage becomes the connecting link between the two shear walls, connecting the relatively independent shear wall units a into a whole, so that they can share the force. It can transmit and disperse horizontal forces more efficiently, greatly improve the structure's resistance to lateral displacement and collapse, and enhance the overall stability of the building.

[0037] Example 1

[0038] like Figures 1 to 4As shown, this embodiment proposes a prefabricated shear wall structure, including several sets of interconnected shear wall units a. Each shear wall unit a includes an inner wall panel 2 and an outer wall panel 1 arranged at intervals. Several sets of connecting plates 3 are fixed on the inner walls of both the inner wall panel 2 and the outer wall panel 1. The two connecting plates 3 are staggered, and each connecting plate 3 is connected to a partition plate 4 at its end, so that the connecting plates 3 and the partition plate 4 form a T-shaped structure. The adjacent partition plates 4 form an inner and outer staggered abutting layout, forming a closed middle tie plate surface. The adjacent connecting plates 3 and the middle partition plate 4 enclose a casting cavity 5.

[0039] Several sets of first through holes 6 are vertically arrayed on the connecting plate 3, and several sets of first horizontal ribs 7 are also included. The first horizontal ribs 7 pass through the corresponding first through holes 6 and extend to the outside of the connecting plate 3. A pair of tie rods are connected between the two first horizontal ribs 7. The several sets of partitions 4 in the middle are further clamped and positioned by the first horizontal ribs 7. Then, concrete is poured between the inner wall panel 2 and the outer wall panel 1 to form a shear wall unit a.

[0040] Compared to the traditional method of using bolts 82 to position two wall panels and resist their displacement, the proposed solution uses staggered connecting plates 3 and mutually abutting partitions 4 to form a T-shaped structure and a closed intermediate tie plate surface. During concrete pouring, the abutting surface of the partitions 4 can transfer stress, upgrading from "point (bolt 82) constraint" to "surface (intermediate tie plate surface + first horizontal reinforcement 7) collaborative constraint," which can more effectively limit the displacement of the inner wall panel 2 and the outer wall panel 1 and improve the overall stability.

[0041] The first horizontal rib 7, which runs through the connecting plate 3, forms a transverse tie system that works in conjunction with the tie rod 8. Compared to traditional tie bolts 82, this design can distribute the stress, enhance internal shear resistance, and make structural deformation more controllable when subjected to loads such as concrete lateral pressure. Furthermore, this design eliminates the need for drilling holes in the wall panel, thus avoiding damage to the wall panel's structural strength and improving the overall aesthetics, achieving a dual optimization of function and appearance.

[0042] Furthermore, the relatively closed pouring cavity 5 formed by the adjacent connecting plate 3 and the surrounding plate, compared with the "open" template gap of the traditional tie bolt 82, can achieve segmented pouring when pouring concrete, optimize the efficiency of pouring and vibration, make it easier to ensure fullness and compactness, and reduce defects such as honeycomb and holes.

[0043] In the above construction process, in order to form a closed intermediate tie plate surface, the distance between two adjacent partitions 4 is less than the maximum width of the partition 4 itself. Therefore, during construction, one of the wall panels needs to be hoisted and then lowered to complete the splicing. To overcome this limitation, in this embodiment, the end of the connecting plate 3 is connected to an insert plate 12, the insert plate 12 is arranged perpendicularly to the connecting plate 3, and the inner side of the partition 4 is provided with a slot 13 that matches the insert plate 12 and is inserted into the insert plate 12.

[0044] pass Figure 2 and Figure 3 It can be seen that when assembling the two wall panels, the maximum width of the insert plate 12 is less than the distance between the two partition plates 4, so it can be spliced ​​by displacement from the side. After the insert plate 12 in the outer wall panel 1 passes between the two insert plates 12 in the inner wall panel 2, the partition plate 4 can be further installed. Align the slot 13 in the partition plate 4 with the slot 13, and then move it downward to achieve the assembly of the partition plate 4. After the inner wall panel 2 and the outer wall panel 1 are pulled together appropriately, the above-mentioned middle pull plate surface is formed.

[0045] During construction, partitions 4 of different thicknesses can be selected according to the current project requirements. To accommodate partitions 4 of different thicknesses, the first horizontal rib 7 needs to have adequate space for movement within the first through hole 6 to facilitate the insertion, installation, and tightening of the first horizontal rib 7. Therefore, in this embodiment, the first through hole 6 is formed by two semi-circular arc-shaped hole ends and two parallel straight-edged hole walls. The two semi-circular arc-shaped hole ends are located at the two ends of the parallel straight-edged hole walls, and the whole is elongated with arc-shaped transitions at both ends.

[0046] In this embodiment, each of the two first transverse reinforcements 7 has a corresponding through hole 81. The aforementioned tie rod 8 includes a bolt 82, which passes through the through hole 81 on the two first transverse reinforcements 7 and is threadedly connected to a nut 83. Tightening the nut 83 and the threaded connection with the bolt 82 can clamp the two first transverse reinforcements 7. For ease of construction, the through hole 81 and the tie rod 8 are both located at both ends of the first transverse reinforcement 7. This design of the first transverse reinforcement 7 not only strengthens the shear strength of the shear wall unit a after it is formed, but also limits the position of the partition plate 4 during concrete pouring, preventing the partition plate 4 from floating.

[0047] Example 2

[0048] refer to Figures 5 to 8 Based on Example 1, a steel cage b is connected between the two shear wall units a, and an outer formwork is built on the outside of the steel cage b. Concrete is poured between the two outer formworks to fix it to the shear walls on both sides through concrete, forming a prefabricated shear wall structure.

[0049] In this design, the steel cage b serves as a connecting link between the two shear walls, linking the relatively independent shear wall units a into a unified whole, allowing them to share the load. This enables more efficient transmission and dispersion of horizontal forces, significantly improving the structure's resistance to lateral displacement and collapse, and enhancing the overall stability of the building.

[0050] In this embodiment, the connecting plate 3 has a number of sets of second through holes 10 arranged vertically, and also includes a number of sets of second horizontal ribs 11. The horizontal lines of the second horizontal ribs 11 pass through the corresponding second through holes 10 and extend to the outside of the connecting plate 3. At least one end of the second horizontal rib 11 is detachably connected to a hook 9, which is hooked to the aforementioned steel cage b.

[0051] Furthermore, the second perforation 10 and the first perforation 6 are staggered vertically, with the second perforation 10 located outside the first perforation 6. The hook 9 connected to the second horizontal reinforcement 11 is hooked onto the vertical reinforcement b1 of the reinforcing cage b. Figure 5 As shown, the hook 9 is placed on the outside, which makes it easier to hook the vertical bar b1 on the steel cage b and establish a connection with the steel cage b.

[0052] In this embodiment, the fastening component 9 includes a threaded sleeve 91 fixed to the end of the second horizontal rib 11. A threaded post 92 is threadedly connected to the inner thread of the threaded sleeve 91, and a screwing handle 98 is connected to the outer wall of the threaded post 92. A rotatable hook 93 is connected to the other end of the threaded post 92. In this design, the subsequent assembly of the fastening component 9 can prevent the second horizontal rib 11 from interfering with the second through hole 10 during the installation process. During the screwing process, the rotatable design can keep the hook 93 facing the direction of the vertical rib b1 at all times, ensuring that after the screwing feed, the hook 93 can fit properly to hook the vertical rib b1 to form a connection with the steel cage b.

[0053] Specifically, such as Figure 8 As shown, a limiting groove 94 is formed in the threaded post 92, and a rotatable limiting post 95 is provided in the limiting groove 94. A limiting ring 96 is connected to the top of the limiting groove 94 to prevent the limiting post 95 from falling out. A connecting post 97 is connected to the limiting post 95. The connecting post 97 passes through the inside of the limiting ring 96 and is connected to the aforementioned hook 93 to ensure that the hook 93 can rotate relative to the threaded post 92.

[0054] This utility model also proposes a construction procedure for a prefabricated shear wall structure, as detailed below:

[0055] S1: The prefabricated inner wall panel 2 and outer wall panel 1 are hoisted to the design position, so that the connecting plates 3 on both sides are staggered. The partition 4 is installed to the end of the connecting plate 3 through the insertion of the insert plate 12 and the slot 13, forming a T-shaped structure. The adjacent partitions 4 are staggered and abutted to enclose the closed middle tie plate surface and the casting cavity 5.

[0056] Several first horizontal bars 7 are initially inserted into the first through hole 6, so that one end of the horizontal bar does not exceed the end face of the inner wall panel 2, so as to reserve space for the lowering of the steel cage b.

[0057] S2: Hoist the prefabricated steel cage b between the two shear wall units a. After the steel cage b is in place, continue to push the first horizontal bar 7 and install the tie rod 8 between the two horizontal first horizontal bars 7, so that the two first horizontal bars 7 will clamp the several sets of partitions 4 located in the middle.

[0058] Insert the second horizontal bar 11 into the second through hole 10, install a bending member at the end of the second horizontal bar 11, and rotate the screw handle 98 to hook the hook 93 onto the vertical bar b1, thereby achieving a mechanical connection between the second horizontal bar 11 and the steel cage b.

[0059] S3: Erect an outer formwork between the two shear wall units a, and then pour concrete between each shear wall and between the two outer formworks (regional pouring can be adopted); after pouring, vibrate to compact, and cure. After it is formed, a prefabricated shear wall structure is formed.

[0060] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
