Description

Technical Field

[0001] This utility model relates to the field of prefabricated and modular building technology, and in particular to a non-dismantling tie-frame shear wall and modular building. Background Technology

[0002] With the rapid development and widespread application of prefabricated and modular buildings, the level of industrialization and integration in the construction industry is constantly improving. However, in existing prefabricated and modular building systems, formwork shear walls generally use a single concrete formwork with reinforcing bars tied between two formworks. Bolts are then used to connect the two formworks through holes, and concrete is poured between the two formworks to form a monolithic formwork shear wall. In this configuration, the concrete formwork does not participate in load-bearing, has poor crack resistance, and wastes concrete materials. Furthermore, the bolts used for tie-downs need to be removed after the concrete is poured, making the on-site construction process cumbersome and reducing construction efficiency.

[0013] The plurality of horizontal stirrups are arranged at intervals, and are wrapped around and tied to the plurality of the first vertical reinforcing bars;

[0014] Multiple tie bars are arranged at intervals and tied to the first vertical steel bar in the middle row.

[0015] According to this utility model, the first vertical reinforcing bar includes a reinforcing bar body and an extension bar, wherein the vertically oriented extension bar is tied to the inner side of the reinforcing bar body, and the upper part of the extension bar of the reinforcing mesh located in the casting cavity extends out from the top of the wall; or,

[0016] The two rows of the first vertical reinforcing bars extend from the top of the wall and bend towards each other.

[0017] According to this utility model, the vertical planar reinforcement includes two second vertical steel bars and a plurality of horizontal tie bars arranged vertically.

[0018] The second vertical reinforcing bar is embedded in the wall and fixed to the reinforcing mesh;

[0019] One end of the horizontal tie bar is embedded in the wall and fixed to a second vertical steel bar, and the other end is fixed to another second vertical steel bar;

[0021] According to this utility model, a support plate that is vertically oriented and fixed to a steel mesh is also pre-embedded in the second wall, and an insertion hole communicating with the mounting hole is opened on the support plate;

[0033] (III) Beneficial Effects

[0034] The beneficial effects of this utility model are:

[0035] On the one hand, the non-removable tie-frame shear wall provided by this utility model, during the factory prefabrication stage, allows the first and second formwork shells to jointly participate in structural stress by pre-embedding steel mesh and vertical planar reinforcement in the first and second walls. This not only saves concrete usage but also improves the integration of the formwork shells and enhances the rigidity, durability, and safety of the wall, effectively suppressing cracking. While meeting the requirements for the thickness of the concrete protective layer outside the reinforcement, this design can reduce the total wall thickness, avoid occupying interior building space, and further save materials.

[0036] The pre-embedded planar reinforcement bars on both sides can be arranged in an interlaced manner to form an integral steel reinforcement skeleton. No on-site reinforcement insertion and tying work is required in the wall area. Only reinforcement cages need to be arranged in the edge area, which significantly reduces the amount of on-site reinforcement construction and improves construction efficiency. The planar reinforcement bars on both sides of the formwork are arranged in an interlaced manner and connected as a whole by cast-in-place concrete, which jointly participates in the structural stress and improves the integration of the formwork and the overall strength of the wall.

[0037] Concrete ribs are incorporated into the wall, effectively increasing the thickness of the first and second formwork shells and enhancing their rigidity and crack resistance. Nuts and mounting holes pre-embedded in the concrete ribs ensure the connection strength after the bolts are screwed in, strengthen the tensile strength of the two formwork shells, and avoid on-site drilling, thus improving construction efficiency.

[0038] Bolts are inserted into the mounting holes and connected to nuts to achieve counter-tensioning, allowing the two mold shells to form a unified whole that shares the load. The bolt heads are embedded inside the mounting holes, eliminating the need for removal after installation, reducing on-site disassembly steps and further improving construction efficiency.

[0039] On the other hand, in the modular building provided by this utility model, the vertical planar reinforcement and the vertical reinforcement of the steel cage both extend beyond the top of the wall. The vertical reinforcement in the lower formwork shear wall is inserted into the casting cavity of the upper formwork shear wall, overlapping and parallel to the vertical reinforcement of the upper vertical planar reinforcement. Similarly, the vertical reinforcement in the steel cage of the lower formwork shear wall is inserted into the upper steel cage, overlapping and parallel to the vertical reinforcement of the upper steel cage. The connection between the upper and lower formwork shear walls is achieved through the pouring of concrete. On-site connection of the vertical reinforcement between the upper and lower layers is not required using threaded sleeves, reducing on-site construction procedures and improving construction efficiency.

[0055] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Example 1

[0057] See Figure 1-10 The non-dismantling tie-frame shear wall proposed in this embodiment includes a first formwork 11, a second formwork 12, a reinforcing cage 3, and bolts 2.

[0058] The first formwork 11 includes a first wall 111, with vertical concrete ribs 13 on its sidewalls, a steel mesh 14 embedded in the first wall 111, vertical planar reinforcement bars 15 partially embedded and perpendicular to the sidewalls of the first wall 111, and nuts 16 embedded in the concrete ribs 13. The second formwork 12 includes a second wall 121, with vertical concrete ribs 13 on its sidewalls, a steel mesh 14 embedded in the second wall 121, vertical planar reinforcement bars 15 partially embedded and perpendicular to the sidewalls of the second wall 121, and mounting holes 1211 that transversely penetrate the concrete ribs 13 and the second wall 121.

[0059] The first mold shell 11 and the second mold shell 12 are arranged opposite each other to form a casting cavity. The vertical planar reinforcement 15 on the two are arranged in an alternating manner. The bolt 2 can be inserted into the mounting hole 1211 and connected to the nut 16, with its head buried in the mounting hole 1211. The reinforcement cage 3 is set in the casting cavity and corresponds to the edge area of ​​the wall. Concrete can be poured into the casting cavity so that the first mold shell 11 and the second mold shell 12 are combined to form a mold shell shear wall 100.

[0060] The first mold shell 11 and the second mold shell 12 are both prefabricated integral components in the factory.

[0061] Based on the above configuration, this non-removable tie-frame shear wall has the following advantages:

[0062] During the prefabrication stage, by pre-embedding steel mesh 14 and vertical planar reinforcement 15 in the first wall 111 and the second wall 121, the first formwork 11 and the second formwork 12 jointly participate in the structural stress. This not only saves concrete usage but also improves the integration of the formwork and enhances the rigidity, durability, and safety of the wall, effectively suppressing cracking. While meeting the requirements for the thickness of the concrete protective layer outside the reinforcement, this design can reduce the total wall thickness, avoid occupying interior building space, and further save materials.

[0063] The pre-embedded planar reinforcing bars 15 on both sides can be arranged in an interlaced manner to form an integral steel reinforcement skeleton. No on-site insertion and binding of reinforcing bars is required in the wall area. Only the reinforcing cage 3 needs to be arranged in the edge area, which significantly reduces the amount of on-site steel reinforcement construction and improves construction efficiency. The planar reinforcing bars 15 on both sides of the formwork are arranged in an interlaced manner and connected into a whole by cast-in-place concrete, which jointly participates in the structural stress and improves the integration of the formwork and the overall strength of the wall.

[0064] Concrete ribs 13 are installed in the wall, which is equivalent to locally increasing the thickness and effectively improving the rigidity and crack resistance of the first formwork 11 and the second formwork 12. Nuts 16 and mounting holes 1211 are pre-embedded in the concrete ribs in the factory, ensuring the connection strength after the bolts 2 are screwed in, enhancing the tensile strength of the two formwork shells, and avoiding on-site drilling, thus improving construction efficiency.

[0065] Bolt 2 is inserted into mounting hole 1211 and connected to nut 16 to achieve counter-tension, so that the two mold shells on both sides form a whole and share the force. The bolt head is embedded in the mounting hole, so it does not need to be removed after installation, reducing on-site disassembly procedures and further improving construction efficiency.

[0066] Preferably, the concrete rib 13 extends from the top to the bottom of the wall, further improving the rigidity and crack resistance of the formwork.

[0067] Preferably, multiple vertical planar reinforcement bars 15 and concrete ribs 13 are provided, and multiple vertical planar reinforcement bars 15 and concrete ribs 13 are staggered along the length of the wall in the wall body area to further improve the rigidity and crack resistance of the formwork.

[0068] Preferably, there are multiple nuts 16 and mounting holes 1211, and the multiple nuts 16 and mounting holes 1211 are arranged in an array along the length and height of the wall to ensure reliable tension between the first mold shell 11 and the second mold shell 12.

[0069] Furthermore, the vertical planar reinforcement 15 and the vertical reinforcement of the steel cage 3 both extend out of the top of the wall and can be inserted into the casting cavity of the upper formwork shear wall 100 to overlap with the vertical reinforcement of the upper formwork shear wall 100, thus achieving an upper and lower overlap. The upper and lower formwork shear walls 100 are then combined into a whole by cast-in-place concrete, improving the connection efficiency.

[0070] Furthermore, the steel cage 3 includes multiple first vertical steel bars 31, multiple horizontal stirrups 32, and multiple tie bars 33.

[0071] Multiple first vertical reinforcing bars 31 are arranged in two rows and multiple columns, with the upper part of the first vertical reinforcing bars 3 of the reinforcing mesh 14 located in the casting cavity extending out of the top of the wall. Multiple horizontal stirrups 32 are arranged vertically at intervals, surrounding and binding the multiple first vertical reinforcing bars 31. Multiple tie bars 33 are arranged vertically at intervals and bound to the first vertical reinforcing bars 31 in the middle row.

[0072] Based on the above configuration, when assembling a multi-layer modular building, the upper part of the first vertical reinforcing bar 3 in the lower formwork shear wall 100 can be inserted into the upper reinforcing cage 3 and overlap parallel to the upper first vertical reinforcing bar 31. A reliable connection between the upper and lower formwork shear walls 100 is achieved by pouring concrete.

[0073] See Figure 6 and Figure 8 Optionally, the first vertical reinforcement 31 includes a reinforcement body 311 and an extension bar 312. Vertically oriented extension bars 312 are tied to the inner side of the reinforcement body 311. The upper part of the extension bars 312 of the reinforcing mesh 14 located in the casting cavity extends out from the top of the first wall 111. The upper part of the lower extension bar 312 can be inserted into the upper reinforcing cage 3 and overlaps parallel to the upper first vertical reinforcement 31. Since the extension bars 312 are tied to the inner side of the reinforcement body 311 and have no obstruction above them, they can be easily inserted into the reinforcing cage 3 of the upper formwork shear wall 100. Therefore, the extension bars 312 can be set as straight bars to simplify the structure and facilitate processing. During on-site construction, the extension bars 312 are tied to the inner side of the reinforcement body 311.

[0074] Of course, the first vertical reinforcement 31 can also be configured as follows: two rows of first vertical reinforcement 31 extend from the top of the first wall 111 and bend towards each other, so that the upper part of the lower first vertical reinforcement 31 can avoid the upper first vertical reinforcement 31 and be inserted into the upper reinforcement cage 3 and arranged parallel and overlapping with the upper first vertical reinforcement 31. This can reduce on-site binding work and improve construction efficiency.

[0075] Furthermore, the vertical planar reinforcement 15 includes two second vertical reinforcement bars 151 and multiple horizontal tie bars 152 arranged vertically.

[0076] A second vertical reinforcing bar 151 is embedded in the wall and fixed to the reinforcing mesh 14. One end of a horizontal tie bar 152 is embedded in the wall and fixed to a second vertical reinforcing bar 151, and the other end is fixed to another second vertical reinforcing bar 151. The two second vertical reinforcing bars 151 extend out from the top of the wall and bend towards each other.

[0077] Based on the above configuration, when forming a multi-layer modular building, the upper part of the second vertical steel bar 151 of the lower formwork shear wall 100 can avoid the wall body and concrete rib 13 of the upper formwork shear wall 100 and be inserted into the casting cavity, and overlap with the upper second vertical steel bar 151 in parallel. Combined with the cast concrete, the upper and lower formwork shear walls 100 are connected, improving the connection efficiency.

[0078] To further improve the strength of the formwork shear wall 100, this embodiment further specifies:

[0079] The two ends of the horizontal steel bars 141 in the steel mesh 14 extend to the edge area of ​​the wall and protrude vertically from the side wall of the wall to form lap joints. The lap joints on the oppositely arranged first and second formwork shells overlap each other, and together with the concrete poured between the first formwork shell 11 and the second formwork shell 12, the anchorage strength and overall coordination between the first formwork shell 11 and the second formwork shell 12 are improved, and the strength of the formed formwork shear wall 100 is further improved.

[0080] Furthermore, to improve tensile strength, this embodiment further specifies:

[0081] The second wall 121 also has a vertically oriented support plate 17 pre-embedded and fixed on the steel mesh 14, and the support plate 17 has a hole for connecting the installation hole 1211.

[0082] During on-site construction, bolt 2 can be inserted into mounting hole 1211 and insertion hole, and the head of bolt 2 abuts against support plate 17 to improve the support strength of bolt 2, thereby improving the tensile strength of first mold shell 11 and second mold shell 12.

[0083] Specifically, horizontally arranged bent steel bars 18 are also pre-embedded in the second wall 121.

[0084] Both ends of the bent steel bar 18 are fixed to the steel mesh 14, and the bent steel bar 18 extends into the concrete rib 13. The support plate 17 is fixed on the bent steel bar 18 to stably fix the support plate 17 in the concrete rib 13, thereby further improving the support strength of the bolt 2, and thus improving the tensile strength of the first mold shell 11 and the second mold shell 12.

[0085] Example 2

[0086] Based on Embodiment 1, this embodiment also provides a modular building, including multiple molded shear walls 100, which are stacked one on top of the other to form a modular building.

[0087] During construction, the vertical reinforcing bars 15 of the lower formwork shear wall 100 are inserted into the casting cavity of the upper formwork shear wall 100, overlapping parallel to the vertical reinforcing bars 15. Similarly, the vertical reinforcing bars 3 of the lower formwork shear wall 100 are inserted into the upper reinforcing cage 3, overlapping parallel to the vertical reinforcing bars 3, thus achieving the lap joint of the upper and lower vertical reinforcing bars. The connection between the upper and lower formwork shear walls 100 is then achieved through the pouring of concrete.

[0088] Therefore, it is not necessary to connect the vertical steel bars of the upper and lower layers through threaded sleeves on site, which reduces on-site construction procedures and improves construction efficiency.

[0089] Furthermore, taking a 100mm two-layer formwork shear wall as an example, the on-site construction method for modular buildings is as follows:

[0090] S1: Hoist the first mold shell 11.

[0091] S2: Tie the steel cage 3.

[0092] S3: Hoist the second mold shell 12 and arrange the first mold shell 11 and the second mold shell 12 opposite to each other.

[0093] S4: Insert bolt 2 into mounting hole 1211 and connect it with nut 16 to complete the pull-out without disassembly.

[0094] S5: Pour concrete into the casting cavity, seal the tie holes, and partially plaster the walls to complete the construction of the first layer of formwork shear wall 100.

[0095] S6: Hoist the first formwork 11 above the first layer shear wall 100.

[0096] S7: Tie the steel cage 3.

[0097] S8: Hoist the second formwork 12 above the first formwork shear wall 100 and arrange the first formwork 11 and the second formwork 12 opposite to each other.

[0098] S4: Insert bolt 2 into mounting hole 1211 and connect it with nut 16 to complete the pull-out without disassembly.

[0099] S5: Pour concrete into the casting cavity, seal the tie holes, and partially plaster the walls to complete the construction of the second layer of formwork shear wall 100.

[0100] Specifically, when the first vertical reinforcing bar 31 includes a reinforcing bar body 311 and an extension bar 312, step S2 further includes: tying the extension bar 312 to the first vertical reinforcing bar 31. Step S7 further includes: making the lower extension bar 312 parallel and overlapping with the upper first vertical reinforcing bar 31, and the lower second vertical reinforcing bar 151 parallel and overlapping with the upper second vertical reinforcing bar 151.

[0101] Specifically, when the two rows of first vertical steel bars 31 extend out of the top of the first wall 111 and bend towards each other, step S7 further includes: making the upper part of the lower second vertical steel bar 151 overlap with the upper second vertical steel bar 151 in parallel to achieve a lap joint, while the upper part of the lower first vertical steel bar 31 is inserted into the upper steel cage 3 so that the lower first vertical steel bar 31 overlaps with the upper first vertical steel bar 31 in parallel to achieve a lap joint.
