[0015] According to this utility model, the steel cage includes a plurality of second vertical steel bars, a plurality of horizontal stirrups, and a plurality of tie bars;
[0016] Multiple second vertical steel bars are arranged in two rows along the thickness direction of the first wall and in multiple rows along the length direction of the first wall. The first row of second vertical steel bars is embedded in the first wall and extends out of the top of the first wall. The second row of second vertical steel bars is located outside the first wall and extends out of the top of the first wall.
[0017] The multiple horizontal stirrups are rectangular and spaced apart vertically, and are wrapped around and tied to the multiple second vertical reinforcing bars, with one side pre-embedded in the first wall.
[0018] Multiple tie bars are arranged at intervals and tied to the second vertical steel bar in the middle row. One end of the tie bar is embedded in the first wall as a straight bar, and the second end is bent.

[0029] (III) Beneficial Effects
[0030] The beneficial effects of this utility model are:
[0031] On the one hand, the hole-free tie-wall shear wall provided by this utility model allows for the factory fabrication of a steel mesh and a steel cage pre-embedded in the first wall and the second wall, ensuring that both the first and second formwork shells participate in load-bearing. This saves concrete materials, improves rigidity, durability, and safety, and prevents cracking. Furthermore, the first and second formwork shells, together with the concrete poured between them, form an integral structure, increasing the integration of the formwork shells, reducing the need for on-site steel mesh tying, and improving construction efficiency. The pre-embedded steel mesh and steel cage in the wall allows for a reduction in the overall wall thickness while meeting the standard requirements for the thickness of the steel reinforcement on the outer surface of the wall. This avoids additional occupation of the building's interior area and also saves concrete materials.
[0032] Meanwhile, the tie rod mounting bases pre-embedded in the walls of the first and second mold shells can insert the connectors, realizing tie rods without drilling holes, which does not affect the decoration, reduces the operation of drilling holes and inserting bolts on site, and improves construction efficiency.
[0033] Furthermore, the vertical reinforcing bars of the steel mesh and steel cage extending beyond the top of the wall can be inserted into the grouting cavity of the upper formwork shear wall and overlap with the vertical reinforcing bars of the upper formwork shear wall, achieving an upper and lower overlap. Combined with cast-in-place concrete, the upper and lower formwork shear walls are integrated into a whole, improving connection efficiency.
[0034] 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 steel mesh of the lower formwork shear wall is inserted into the grouting cavity of the upper formwork shear wall, overlapping and parallel to the vertical reinforcement of the upper steel mesh. 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 using threaded sleeves is unnecessary, reducing on-site construction procedures and improving construction efficiency.

[0049] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 6 The orientation is used as a reference.
[0050] Example 1
[0051] See Figure 1-9 The hole-free tie-shell shear wall proposed in this embodiment includes a first mold shell 11, a second mold shell 12, and a connector 3.
[0052] The first formwork 11 includes a first wall 111, a steel mesh 13 embedded in the wall body of the first wall 111, a steel cage 14 partially embedded at the edge of the first wall 111, and tie rod mounting bases 15 partially embedded in the wall body of the first wall 111. The second formwork 12 includes a second wall 121, a steel mesh 13 embedded in the wall body of the second wall 121, and tie rod mounting bases 15 partially embedded in the wall body of the second wall 121. The vertical steel bars of the steel mesh 13 and the steel cage 14 extend out from the top of the wall.
[0053] A grouting cavity is formed between the first mold shell 11 and the second mold shell 12 arranged opposite to each other. The tie rod mounting seats 15 on the two are arranged opposite to each other. The connector 3 can be inserted into and connected to the opposite tie rod mounting seats 15. Concrete can be poured into the grouting cavity so that the two first mold shells 11 and the second mold shell 12 form a mold shell shear wall 100.
[0054] Based on the above configuration, this hole-free design has the following effects on the formwork shear wall:
[0055] During factory fabrication, reinforcing mesh 13 and reinforcing cage 14 are pre-embedded in the first wall 111 and in the second wall 121, so that both the first formwork 11 and the second formwork 12 participate in load-bearing. This saves concrete materials, improves rigidity, durability, and safety, and prevents cracking. Furthermore, the first and second formwork 11 and the concrete poured between them form an integral structure, improving formwork integration, reducing the need for on-site reinforcing mesh tying, and increasing construction efficiency. The pre-embedded reinforcing mesh 13 and reinforcing cage 14 in the wall allows for a reduction in the overall wall thickness while meeting standard requirements for the thickness of the reinforcing bars on the outer surface of the wall. This avoids additional occupation of the building's interior area and saves concrete materials.
[0056] See Figure 6 and 7 Meanwhile, the tie rod mounting bases 15 pre-embedded in the walls of the first mold shell 11 and the second mold shell 12 can insert the connector 3, realizing tie rods without drilling holes, improving the integration of the mold shells, not affecting the decoration, and reducing construction steps such as installing tie rods, pouring concrete, disassembling tie rods, and sealing holes, making the construction process more convenient and faster.
[0057] See Figure 6 , Figure 8-9 Furthermore, the vertical reinforcing bars of the steel mesh 13 and the steel cage 14 extending out of the top of the wall can be inserted into the grouting cavity of the upper formwork shear wall 100 and overlap with the vertical reinforcing bars of the upper formwork shear wall 100 in parallel, thus achieving an upper and lower overlap. Combined with the cast-in-place concrete, the upper and lower formwork shear walls 100 are integrated into a whole, improving the connection efficiency.
[0058] See Figure 3 and Figure 5 Furthermore, the opposing sidewalls of the wall areas of the first wall 111 and the second wall 121 are provided with a plurality of concrete ribs 16 at intervals along their respective length directions, and the concrete ribs 16 extend from the top to the bottom of the wall. The concrete ribs 16 can improve the rigidity and crack resistance of the first mold shell 11 and the second mold shell 12.
[0059] It should be noted that the concrete rib 16 is prefabricated in the factory and is an integral concrete structure with the wall.
[0060] See Figure 6 and 7 Furthermore, the upper part of the first vertical steel bar 131 of the steel mesh 13 is bent toward the grouting cavity and toward the adjacent concrete ribs 16.
[0061] When forming a multi-layer modular building, the first vertical steel bar 131 of the lower formwork shear wall 100 can avoid the wall and concrete rib 16 of the upper formwork shear wall 100 and be inserted into the grouting cavity, and overlap with the first vertical steel bar 131 of the upper formwork shear wall 100 in parallel, and then combine with the poured concrete to realize the connection between the upper and lower formwork shear walls 100.
[0062] See Figure 6 Preferably, the two ends of the horizontal steel bars 132 in the steel mesh 13 extend to the edge area of the wall and extend vertically out of the side wall of the wall to form an overlap.
[0063] The overlapping portions on the first formwork 11 and the second formwork 12 are interlocked, and the concrete poured between the first formwork 11 and the second formwork 12 improves the anchoring strength and overall coordination between the first formwork 11 and the second formwork 12, thereby further improving the strength of the formed formwork shear wall 100.
[0064] See Figure 3 Furthermore, to achieve reliable tension between the first mold shell 11 and the second mold shell 12, this embodiment further specifies:
[0065] The number of tie rod mounting bases 15 is multiple. The multiple tie rod mounting bases 15 are arranged in an array along the length and height directions of the first wall 111 or the second wall 121, and the tie rod mounting bases 15 and the concrete ribs 16 are arranged alternately.
[0066] Setting a large number of tie rods 15 ensures reliable tie-fitting between the first mold shell 11 and the second mold shell 12. The tie rods 15 and the concrete ribs 16 are arranged in an alternating manner to ensure that the distance between the first mold shell 11 and the second mold shell 12 is sufficient to accommodate larger tie rods 15, thereby further ensuring the tie strength.
[0067] See Figure 3 and Figure 5 Furthermore, the specific structure of the reinforcing cage 14 is as follows:
[0068] The steel cage 14 includes multiple second vertical steel bars 141, multiple horizontal stirrups 142, and multiple tie bars 143.
[0069] Multiple second vertical reinforcing bars 141 are arranged in two rows along the thickness direction of the first wall 111 and in multiple rows along the length direction of the first wall 111. The first row of second vertical reinforcing bars 141 is embedded in the first wall 111 and extends out of the top of the first wall 111. The second row of second vertical reinforcing bars 141 is located outside the first wall 111, with its upper part extending out of the top of the first wall 111. Multiple horizontal stirrups 142 are rectangular and arranged at intervals, surrounding and binding the multiple second vertical reinforcing bars 141, with one side embedded in the first wall 111. Multiple tie bars 143 are arranged at intervals and bound to the middle row of second vertical reinforcing bars 141, with the first end being a straight bar embedded in the first wall 111 and the second end bent.
[0070] During factory preparation, multiple second vertical steel bars 141, multiple horizontal stirrups 142 and multiple tie bars 143 are first tied into a steel cage 14, and then one side of the first row of second vertical steel bars 141, horizontal stirrups 142 and the first end of tie bars 143 are cast and embedded in the first wall 111.
[0071] See Figure 6 , Figure 8 and Figure 9 Based on the above configuration, when assembling a multi-layer modular building, the upper parts of the first and second vertical reinforcing bars 141 in the lower formwork shear wall 100 can be inserted into the upper reinforcing cage 14. Specifically, the upper parts of the lower second vertical reinforcing bars 141 are arranged parallel and overlapping with the upper first column of second vertical reinforcing bars 141, and the upper parts of the lower second column of second vertical reinforcing bars 141 are also parallel and overlapping with the upper second column of second vertical reinforcing bars 141. A reliable connection between the upper and lower formwork shear walls 100 is achieved by pouring concrete. The tie bars 143 extend from the second end of the first wall 111 and are bent into an enclosed space to facilitate the insertion of the lower second column of second vertical reinforcing bars 141.
[0072] Specifically, the upper part of the first column of second vertical steel bars 141 bends outward toward the first wall 111 to avoid the upper first wall 111 and is inserted into the upper steel cage 14 and arranged in parallel and overlapping arrangement with the upper first column of second vertical steel bars 141.
[0073] Optionally, the second vertical reinforcement 141 in the second column includes a reinforcement body 1411 and an extension bar 1412. Vertically oriented extension bars 1412 are tied to the inner side of the reinforcement body 1411, with the upper part of the extension bar 1412 extending beyond the top of the first wall 111. The upper part of the lower extension bar 1412 can be inserted into the upper reinforcement cage 14.
[0074] It overlaps parallel to the second vertical reinforcing bar 141 in the second column above. Since the extension bar 1412 is tied to the inside of the reinforcing bar body 1411 and has no obstruction above it, it can be smoothly inserted into the reinforcing cage 14 of the upper formwork shear wall 100. Therefore, the extension bar 1412 can be set as a straight bar to simplify the structure and facilitate processing. During on-site construction, the extension bar 1412 is tied to the inside of the reinforcing bar body 1411.
[0075] Of course, the second column of second vertical reinforcing bars 141 can also be configured such that the upper part of its extension from the top of the first wall 111 bends towards the upper part of the first column of second vertical reinforcing bars 141, so that the upper part of the lower column of second vertical reinforcing bars 141 can avoid the upper column of second vertical reinforcing bars 141 and be inserted into the upper reinforcing cage 14 and arranged parallel and overlapping with the upper column of second vertical reinforcing bars 141. This can reduce on-site binding work and improve construction efficiency.
[0076] Furthermore, the specific structure of the tension structure is as follows:
[0077] The cross-section of the pull-out mounting base 15 is C-shaped, and the openings of the pull-out mounting bases 15 of the first mold shell 11 and the second mold shell 12 arranged opposite each other are opposite. The connector 3 includes a connecting plate 31 and two plug-in plates 32. The connecting plate 31 is vertically oriented, and the two plug-in plates 32 are vertically fixed to the horizontal ends of the connecting plate 31. The two plug-in plates 32 can be inserted from top to bottom into the two opposite pull-out mounting bases 15 for convenient connection of the two pull-out mounting bases 15.
[0078] Specifically, a mounting body 33 is fixedly provided on the top of the connecting plate 31. The mounting body 33 can be threaded to the bottom of the vertical rod 2. The vertical rod 2 connected to the mounting body 33 can drive the connecting piece 3 to extend into the grouting cavity, and allow the two plug-in plates 32 to be inserted into the two opposing pull-up mounting seats 15.
[0079] During on-site construction, the operator first connects the bottom thread of the vertical rod 2 to the mounting body 33, then inserts the connector 3 downward between the first mold shell and the second mold shell through the vertical rod 2, adjusts the angle of the connector 3 to avoid the upper tie rod mounting seat 15, and inserts the connector 3 into the tie rod mounting seat 15 from bottom to top, and then rotates the vertical rod 2 in the opposite direction to make the vertical rod 2 detach from the mounting body 33.
[0080] Specifically, the mounting body 33 is preferably a sleeve with internal threads, and the bottom of the vertical rod 2 can be inserted into and threadedly connected to the mounting body 33. Of course, the mounting body 33 can also be a rod with external threads, and the bottom of the vertical rod 2 can be sleeved onto and threadedly connected to the mounting body 33.
[0081] Example 2
[0082] See Figure 6 , Figure 8 and Figure 9 Based on Embodiment 1, this embodiment also provides a modular building, which includes multiple shear walls 100 stacked one on top of the other to form a modular building.
[0083] During construction, the vertical reinforcing bars in the steel mesh 13 of the lower formwork shear wall 100 are inserted into the grouting cavity of the upper formwork shear wall 100, overlapping parallel to the vertical reinforcing bars of the upper steel mesh 13. Similarly, the vertical reinforcing bars in the steel cage 14 of the lower formwork shear wall 100 are inserted into the steel cage 14 of the upper formwork shear wall 100, overlapping parallel to the vertical reinforcing bars of the upper steel cage 14, 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.
[0084] 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.
[0085] Specifically, the lower first vertical bar 131 overlaps with the upper first vertical bar 131 in parallel to achieve a lap joint, and the lower extension bar 1412 overlaps with the upper second vertical bar 141 in parallel to achieve a lap joint.
[0086] Furthermore, taking a two-layer formwork shear wall 100 as an example, the construction method of modular buildings is as follows: S1: hoist the first formwork 11.
[0087] S2: Hoist the second mold shell 12 and arrange the first mold shell 11 and the second mold shell 12 opposite to each other.
[0088] S3: The connector 3 can be inserted into and connected to the corresponding pull-out mounting base 15 to achieve pull-out without drilling.
[0089] S4: Pour concrete into the grouting cavity to complete the construction of the first layer of formwork shear wall 100.
[0090] S5: Hoist the first formwork 11 above the first layer shear wall 100.
[0091] S6: 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, and make the lower first vertical steel bar 131 overlap with the upper first vertical steel bar 131 in parallel to achieve a lap joint, and the lower extension bar 1412 overlap with the upper second vertical steel bar 141 in parallel to achieve a lap joint.
[0092] S7: The connector 3 can be inserted into and connected to the corresponding pull-out mounting base 15 to achieve pull-out without drilling.
[0093] S8: Pour concrete into the grouting cavity, seal the tie holes, and partially plaster the wall to complete the construction of the second layer of formwork shear wall 100.
[0094] Specifically, when the second column of second vertical reinforcing bars 141 includes a reinforcing bar body 1411 and an extension bar 1412, step S1 further includes: after hoisting the first formwork shell 11, the extension bar 1412 is then tied to the inner side of the second column of second vertical reinforcing bars 141. Step S5 further includes: making the lower first vertical reinforcing bar 131 overlap with the upper first vertical reinforcing bar 131 in parallel to achieve a lap joint, and inserting the upper part of the lower first column of second vertical reinforcing bars 141 and the extension bar 1412 into the upper reinforcing cage 14, so that the lower first column of second vertical reinforcing bars 141 overlaps with the upper first column of second vertical reinforcing bars 141 in parallel to achieve a lap joint, and the lower extension bar 1412 overlaps with the upper second vertical reinforcing bar 141 in parallel to achieve a lap joint.
[0095] Specifically, when the upper part of the second column of second vertical steel bars 141 extends out of the top of the first wall 111 and bends towards the upper part of the first column of second vertical steel bars 141, step S5 further includes: making the lower first vertical steel bar 131 overlap with the upper first vertical steel bar 131 in parallel to achieve a lap joint, and inserting the upper part of the lower first column of second vertical steel bars 141 and the upper part of the second column of second vertical steel bars 141 into the upper steel cage 14, so that the lower first column of second vertical steel bars 141 overlaps with the upper first column of second vertical steel bars 141 in parallel to achieve a lap joint, and the lower second column of second vertical steel bars 141 overlaps with the upper second vertical steel bars 141 in parallel to achieve a lap joint.
