[0003] Therefore, it is necessary to provide a concrete module sleeve ring connection structure with steel sections, which can solve the problems in the prior art that the concrete module system formwork wall occupies the sleeve area, the node steel bar connection is complicated, and there are many wet operations on site. Summary of the invention

[0005] The present invention is achieved in that:
[0006] A concrete module sleeve connection structure with steel sections is used to connect a fully prefabricated shear wall of a concrete module box with a shear wall. The shear wall comprises a single-sided superimposed shear wall and a sleeve connection assembly. The steel bars in the single-sided superimposed shear wall are tied and connected with the steel bars in the fully prefabricated shear wall of the concrete module box. Two single-sided superimposed shear walls are arranged superimposedly, and an overlapping gap is left between the two single-sided superimposed shear walls. The sleeve connection assembly is located in the overlapping gap and connects the two single-sided superimposed shear walls to form a superimposed shear wall that participates in structural stress.
[0007] The sleeve connection assembly comprises a connecting sleeve and a sleeve connection steel bar; the connecting sleeve is an annular structure, one end of the connecting sleeve is anchored in the single-sided composite shear wall, and the other end of the connecting sleeve extends into the composite gap, so that when two single-sided composite shear walls are overlapped and connected, the other ends of the connecting sleeves on the two single-sided composite shear walls intersect, and the sleeve connection steel bar is inserted into the intersection area of the two connecting sleeves.
[0008] The on-site additional channel steel is inserted into the intersection area of the two connecting rings at the end of the single-sided composite shear wall. The on-site additional channel steel passes through the composite shear wall from top to bottom, and the upper and lower adjacent on-site additional channel steels are fixedly connected.
[0009] An additional connecting steel bar is provided in the overlapping gap, the upper part of the additional connecting steel bar is inserted into the overlapping gap of the overlapping shear wall located in the upper layer, and is connected to the ring connecting steel bar in the overlapping gap, and the lower part of the additional connecting steel bar is inserted into the overlapping gap of the overlapping shear wall located in the lower layer, and is connected to the ring connecting steel bar in the overlapping gap, so that the upper and lower adjacent overlapping shear walls are fixedly connected.
[0010] The single-sided composite shear wall has an edge closing formed at one edge within the composite gap, and the edge closing narrows the composite gap from the inside to the edge. One end of the single-sided composite shear wall away from the concrete module box prefabricated shear wall is connected to the edge component through a closing connection sleeve.
[0011] The width of the overlapping gap at the edge closing is not less than 20 mm.

DETAILED DESCRIPTION
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Please see attached Figure 1 To Attachment Figure 3 A concrete module sleeve connection structure with steel sections is provided, and the connection structure is used to connect a concrete module box prefabricated shear wall 1 and a shear wall. The shear wall includes a single-sided composite shear wall 7 and a sleeve connection assembly; the steel bars in the single-sided composite shear wall 7 are tied and connected with the steel bars in the concrete module box prefabricated shear wall 1, and the two single-sided composite shear walls 7 are arranged in a superimposed manner, and an overlapping gap is left between the two single-sided composite shear walls 7. The sleeve connection assembly is located in the overlapping gap, and the two single-sided composite shear walls 7 are connected to form a composite shear wall that participates in structural force.
[0024] The two single-sided composite shear walls 7 are connected by a sleeve connection assembly, which makes the construction of the composite shear wall convenient and reduces on-site wet work. Compared with the traditional concrete module system formwork wall, the composite shear wall has a simpler connection method and is easier to prefabricate. The composite shear wall has high structural strength and can directly participate in structural stress, reducing the occupied area of the suite, thereby improving the room rate.
[0025] Please see attached Figure 1 The sleeve connection assembly includes a connecting sleeve 3 and a sleeve connection steel bar 4; the connecting sleeve 3 is annular in structure, one end of the connecting sleeve 3 is anchored in the single-sided composite shear wall 7, and the other end of the connecting sleeve 3 extends into the composite gap, so that when two single-sided composite shear walls 7 are overlapped and connected, the other ends of the connecting sleeves 3 on the two single-sided composite shear walls 7 intersect, and the sleeve connection steel bar 4 is inserted into the intersection area of the two connecting sleeves 3.
[0026] Preferably, the connecting ring 3 can be made of steel bars, which are bent into an elliptical structure and connected end to end to form a closed loop. One end of the connecting ring 3 is anchored in the single-sided composite shear wall 7 when the single-sided composite shear wall 7 is prefabricated, and the other end of the connecting ring 3 is located outside the single-sided composite shear wall 7, which is convenient for inserting the ring to connect the steel bars 4 and facilitating the prefabrication of the single-sided composite shear wall 7.
[0027] Preferably, the ring-connecting steel bars 4 can be made of steel bars with a diameter of 16 mm. When the single-sided composite shear walls 7 are overlapped, the width of the intersection area of the two connecting rings 3 is slightly larger than 16 mm, thereby ensuring that the ring-connecting steel bars 4 are inserted into the intersection area of the two connecting rings 3, and the two single-sided composite shear walls 7 are overlapped and connected through the connecting rings 3 and the ring-connecting steel bars 4.
[0028] The plane where the connecting ring 3 is located is located in the horizontal plane, and the ring connecting steel bar 4 is arranged vertically to ensure the reliable connection of the two single-sided composite shear walls 7. The connection method of inserting the ring connecting steel bar 4 to the intersection area of the connecting ring 3 simplifies the construction process, greatly reduces the workload of on-site steel bar binding, and avoids on-site wet operations.
[0029] The connecting rings 3 can be arranged in a matrix on the single-sided composite shear wall 7. The number of connecting rings 3 on the same vertical line can be adaptively adjusted according to actual connection requirements. The length of the ring connecting steel bars 4 is consistent with the height of the single-sided composite shear wall 7, and the number of ring connecting steel bars 4 is consistent with the number of columns in the connecting ring 3 matrix.
[0030] Please see attached Figure 1 and attached Figure 3 The on-site additional channel steel 2 is inserted into the intersection area of the two connecting rings 3 at the end of the single-sided composite shear wall 7. The on-site additional channel steel 2 passes through the composite shear wall from top to bottom, and the upper and lower adjacent on-site additional channel steels 2 are fixedly connected by welding.
[0031] Preferably, the additional channel steel 2 on site can be a channel steel with a specification of 80, and the specification and model of the additional channel steel 2 on site can be adaptively selected according to actual construction requirements. The upper and lower adjacent additional channel steels 2 on site are welded into a whole, which can improve the structural strength of the composite shear wall, so that it can effectively participate in the structural stress, avoiding the problem in the prior art that the concrete embedded module only serves as the filling of the main structure and does not participate in the structural stress, but needs to occupy the internal area and affect the room rate.
[0032] Please see attached Figure 2An additional connecting steel bar 5 is provided in the overlapping gap, the upper part of the additional connecting steel bar 5 is inserted into the overlapping gap of the overlapping shear wall located in the upper layer, and is connected to the ring connecting steel bar 4 in the overlapping gap, and the lower part of the additional connecting steel bar 5 is inserted into the overlapping gap of the overlapping shear wall located in the lower layer, and is connected to the ring connecting steel bar 4 in the overlapping gap, so that the upper and lower adjacent overlapping shear walls are fixedly connected.
[0033] Preferably, the additional connecting steel bar 5 is not less than 1.1 times the longitudinal force-bearing steel bar of the same cross-section shear wall. The additional connecting steel bar 5 is used to be inserted into the overlapping gap between the upper and lower layers of the superimposed shear wall, and overlap the upper and lower layers of the sleeve connecting steel bars 4, so as to fix the upper and lower adjacent superimposed shear walls into a whole, ensuring the connection reliability and longitudinal force bearing capacity. The lap length of the additional connecting steel bar 5 and the sleeve connecting steel bar 4 is ≥1.2LaE, where LaE is the seismic anchorage length of the steel bar, and LaE is determined by the actual design and construction requirements.
[0034] Please see attached Figure 1 The single-sided composite shear wall 7 is provided with an edge closing 8 at one edge of the composite gap, and the edge closing 8 narrows the composite gap from the inside to the edge. One end of the single-sided composite shear wall 7 away from the concrete module box prefabricated shear wall 1 is connected to the edge member through a closing connection sleeve 9.
[0035] By setting the edge closing 8, the overlapping gap between the two single-sided overlapping shear walls 7 is narrowed, so that the single-sided overlapping shear wall 7 and the edge member can be connected by the closing connection sleeve 9. The closing connection sleeve 9 can adopt the grouting sleeve of the prior art.
[0036] Preferably, the width of the overlapping gap at the edge closing 8 is not less than 20 mm.
[0037] Please see attached Figure 1 The upper and lower adjacent fully prefabricated shear walls 1 of the concrete module boxes are fixedly connected by grouting connection sleeves 6 .
[0038] The conventional connection method of the grouting connection sleeve 6 and the fully prefabricated shear wall will not be described in detail here.
[0039] Please see attached Figure 2 and attached Figure 3 The floor slab connected to the composite shear wall includes a module structure top slab 10 and a module structure bottom slab 12; a post-casting area is reserved between the module structure top slab 10 and the module structure bottom slab 12, and steel bars are tied and concrete is poured in the post-casting area to form a post-casting area floor slab 11, and the post-casting area floor slab 11 is connected to the module structure top slab 10 and the module structure bottom slab 12 as a whole.
[0040] The thickness of the composite shear wall is determined according to the thickness of the module structure top plate 10, the post-casting area floor 11 and the module structure bottom plate 12, so that the thickness of the composite shear wall is consistent with the total thickness of the module structure top plate 10, the post-casting area floor 11 and the module structure bottom plate 12. The plate thickness of the single-sided composite shear wall 7 is not less than 50mm.
[0041] Preferably, the module construction top plate can adopt conventional composite floor plates in the prior art, and the module construction bottom plate 12 can adopt conventional construction bottom plates in the prior art, and the specifications thereof can be adaptively selected according to actual construction requirements.
[0042] Please see attached Figure 1 To Attachment Figure 3 , the construction method of the present invention is:
[0043] The shear wall at the connection between the concrete module box fully prefabricated shear wall 1 and the module wall body is set as a composite shear wall to replace the traditional concrete module system formwork wall. The steel bars of the single-sided composite shear wall 7 are anchored into the concrete module box fully prefabricated shear wall 1.
[0044] The prefabricated single-sided composite shear wall 7 with connecting collar 3 is placed at the shear wall at the joint of the module wall body. The collar connecting steel bars 4 are inserted into the intersection area of the connecting collars 3 of the two single-sided composite shear walls 7 on site. At the same time, additional connecting steel bars 5 are arranged in the overlapping gap of the upper and lower composite shear walls to overlap the collar connecting steel bars 4 of the upper and lower composite shear walls. The additional connecting steel bars 5 shall not be less than 1.1 times the longitudinal force-bearing steel bars of the shear wall with the same cross-section.
[0045] The additional channel steel 2 is inserted into the intersection area of the connecting collars 3 at both ends of the single-sided composite shear wall 7 to improve the structural strength and longitudinal force performance of the composite shear wall, so that it can directly participate in the structural force, solving the problem that the formwork wall of the concrete module system does not participate in the structural force and occupies the area inside the sleeve. The additional channel steel 2 of the upper and lower adjacent layers is welded and connected.
[0046] The edge of the single-sided composite shear wall 7 is closed to form an edge closing 8, and a 20 mm gap is reserved between the edge closings 8 of the two single-sided composite shear walls 7. The edge closing 8 is connected to the edge components by a closing connection sleeve 9.
[0047] The steel bars in the single-sided composite shear wall 7 are anchored into the floor slab, so that the composite shear wall is connected and fixed to the floor slab. The steel bars are tied in the post-casting area between the module structure top plate 10 and the module structure bottom plate 12, and concrete is poured to form the post-casting area floor slab 11 and connect the module structure top plate 10 and the module structure bottom plate 12 into a floor slab with an integrated structure.
