Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated structures, and particularly to a building system for rapid assembly of a pentahedron concrete flipping module and an assembly method thereof. Background Art

[0002] In the traditional precast concrete shear wall structure system, dry connection methods such as sleeve grouting connection and bolt connection are mostly used between precast walls. The advantages are high production efficiency and low construction cost. However, during on-site assembly, there are a large number of joints between adjacent walls, the node connection is complex, and a large number of temporary supports are required, making it difficult to give full play to the efficiency advantages of the prefabricated structure.

[0003] In recent years, with the transformation and upgrading of the construction industry, concrete modular buildings have gradually attracted wide attention in various fields. The simple concrete module structure applicable to low-rise buildings has been applied in many projects such as rural houses and dormitories. In existing concrete modular buildings, the modules generally adopt precast or laminated forms, and adjacent modules are arranged closely. The key problem to be solved is the connection between adjacent modules. Especially for two modules arranged closely on the same floor, the "double-wall" problem will occur. How to appropriately split the structure to avoid the "double-wall" appearance and how to achieve convenient and reliable connection between modules are the difficulties of concrete modular buildings. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned existing building system for rapid assembly of a pentahedron concrete flipping module, the present invention is proposed.

[0005] Therefore, the object of the present invention is to provide a building system for rapid assembly of a pentahedron concrete flipping module.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: including,

[0007] Multiple three-dimensional precast concrete modules with a C-shaped plane, the three-dimensional precast concrete modules are composed of walls and floors, and can be freely combined to form functional spaces to meet the building use requirements. The three-dimensional precast concrete modules adopt a flipping production method;

[0008] The flipping production method is that after demolding and when the concrete strength reaches the design requirements, the precast concrete module is flipped 90 degrees or 180 degrees to form a three-dimensional precast concrete module with a C-shaped plane.

[0009] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module of the present invention, among them: the three-dimensional precast concrete module flipped 90 degrees includes five faces, composed of a top plate, a bottom plate and three walls. During production, the side without a wall faces downwards, the top plate and the bottom plate are perpendicular to the ground, and after flipping, the module includes both the top plate and the bottom plate.

[0010] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: the three-dimensional precast concrete module that is flipped 180 degrees includes two forms of four sides or five sides, and is composed of a top plate and several wall bodies. During production, the wall bodies are all perpendicular to the ground, and the floor slab is located on top of the wall bodies. After flipping, the opening of the module faces upwards, and the top plate of the module is transformed into the bottom plate.

[0011] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: the vertical joints between the horizontally adjacent three-dimensional precast concrete modules are connected by grouting with steel anchor rings, and the horizontal joints between the vertically adjacent modules are connected by steel bar slurry anchors to achieve the collaborative force transmission of the wall bodies. The adjacent floor slabs are connected by lap joint of circular steel bars to ensure reliable horizontal connection of the floor slabs.

[0012] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: when the three-dimensional precast concrete module that is flipped 180 degrees adopts the five-side form, only the top surface is open after flipping 180 degrees, and they need to be arranged at intervals to realize the large space of the building while avoiding the situation of "double-wall" connection. The horizontally adjacent three-dimensional precast concrete modules are connected by beam and slab, and the beam and slab can be in precast form, can be set independently, or can be designed as an integrated precast member of beam and slab.

[0013] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: the wall body adopts a fully precast form, with door and window openings left on its surface, reinforcement protruding from the top surface, pre-embedded metal corrugated pipes arranged at the bottom, and pre-embedded threaded sleeves arranged on the side.

[0014] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: a mortar bedding layer is left between two vertically adjacent three-dimensional precast concrete modules, and its thickness is not less than 20 mm.

[0015] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: the floor slab adopts a fully precast form. When the space span is relatively large, the floor slab can adopt a closely assembled prestressed fully precast slab, and a post-cast strip is arranged at the end of the floor slab.

[0016] As a preferred solution of the building system for rapid assembly of the pentahedron concrete flipping module according to the present invention, wherein: the horizontal joints and vertical joints between the wall bodies are all filled with high-strength grouting material to ensure reliable connection between the wall bodies.

[0017] The present invention also provides an assembly method.

[0018] The present invention provides the following technical solution: An assembly method, including a building system for rapid assembly of the pentahedron concrete flipping module, the method comprising the following steps:

[0019] S1: Construct the three-dimensional precast concrete module. The three-dimensional precast concrete module has two production methods. One is the three-dimensional precast concrete module that is flipped by 90 degrees, that is, the side without the wall faces down during production, and the top plate and the bottom plate are perpendicular to the ground. The other is the three-dimensional precast concrete module that is flipped by 180 degrees, that is, the walls are perpendicular to the ground during production, and the floor slab is located on top of the walls.

[0020] S2: Flip the three-dimensional precast concrete module. After demoulding and when the concrete strength reaches the design requirements, flip the three-dimensional precast concrete module by 90 degrees or 180 degrees to complete the hoisting and positioning of the module.

[0021] S3: First fix the position of one three-dimensional precast concrete module, then hoist another three-dimensional precast concrete module to the same height as this three-dimensional precast concrete module. After aligning the walls on both sides, connect the vertical joints between the walls. Subsequently, hoist and install the remaining three-dimensional precast concrete modules one by one. After all the modules are installed, fill all the vertical joints with high-strength grouting material.

[0022] S4: Align the floor slabs. The joints should be filled with polymer-modified cement mortar. Subsequently, install the ring-shaped steel bars at the post-cast strip position at the end of the slab and lap-connect them with the protruding steel bars at the end of the slab. Finally, pour concrete to achieve the horizontal connection of the floor slabs.

[0023] S5: Hoist the upper three-dimensional precast concrete module, align the walls of the upper and lower three-dimensional precast concrete modules, and lower it vertically. Then connect the horizontal joints between the upper and lower walls. A mortar bedding layer should be reserved between the upper and lower three-dimensional precast concrete modules. After the assembly of the three-dimensional precast concrete modules is completed, fill all the horizontal joints with high-strength grouting material.

[0024] Repeat steps S3 to S5 to complete the assembly of all the three-dimensional precast concrete modules in the whole building.

[0025] When the three-dimensional precast concrete module is an 180-degree flipping module including four sides, the following steps are further included:

[0026] S6: Hoist the floor slab of the top floor, lower it vertically to the top of the wall, and connect the floor slab and the wall. After all the installations are completed, fill all the post-cast areas with concrete.

[0027] S7: The assembly of the three-dimensional precast concrete module can also adopt a combination of 90-degree flipping and 180-degree flipping including four sides, that is, the three-dimensional precast concrete module with 180-degree flipping is used from the first floor to the second floor from the bottom, ensuring that each layer of the three-dimensional precast concrete module has a bottom slab, and the three-dimensional precast concrete module with 90-degree flipping is used on the top floor, so that the top floor contains both a top slab and a bottom slab, thus avoiding the secondary assembly of the floor slab and wall on the top floor;

[0028] S8: When the three-dimensional precast concrete module is an 180-degree flipping module including five sides, its installation steps are the same as those of the 180-degree flipping module including four sides above. The only difference is that in order to achieve a large-space layout, the horizontally adjacent modules are connected by precast beams and precast slabs. Therefore, only step S3 needs to be replaced with step S9, which is specifically as follows:

[0029] S9: First, fix the positions of two of the three-dimensional precast concrete modules, then lift the precast beam and precast slab, and connect the beam and slab with the left and right three-dimensional precast concrete modules, so as to achieve a large-space area. After all the three-dimensional precast concrete modules and the connection structure are installed, all the post-cast areas are filled with high-strength grouting material.

[0030] Advantages of the present invention:

[0031] (1) The precast module includes a floor slab and a wall panel. The multi-sided wall is precast integrally, achieving a high precast rate in the factory, with few on-site joints, greatly shortening the construction period and reducing the construction cost.

[0032] (2) The joint connection between the walls not only avoids complex operations such as traditional sleeve grouting, the connection process is simple and the construction quality is easy to guarantee. At the same time, it avoids the "double-wall" connection problem existing in the existing concrete module structure, with a simple structure and convenient construction.

[0033] (3) The whole-assembly construction can be realized on-site, achieving support-free or less-support operation, reducing the amount of complex connection operations, and saving the measure cost;

[0034] (4) The production of the precast module is convenient, without complex molds and advanced production lines, with a wide range of applications, and the construction process is simple, which is easy for construction workers to master. Description of the Drawings

[0054] Embodiment 1

[0055] Referring to Figures 1 to 8 , for the first embodiment of the present invention, a building system for rapid assembly of a five-sided concrete flipping module is provided. This device includes

[0056] Multiple three-dimensional precast concrete modules 100 with a C-shaped plane. The three-dimensional precast concrete module 100 is composed of a wall 110 and a floor 120, and can be freely combined to form functional spaces to meet the requirements of building use. The three-dimensional precast concrete module 100 adopts a flipping production method.

[0057] The flipping production method is that when the concrete strength reaches the design requirement after demolding, the precast concrete module is flipped 90 degrees or 180 degrees to form a three-dimensional precast concrete module 100 with a C-shaped plane.

[0058] Specifically, the three-dimensional precast concrete module 100 flipped 90 degrees includes five sides, consisting of a top plate, a bottom plate, and three walls 110. During production, the side without the wall 110 faces downwards, and the top plate and the bottom plate are perpendicular to the ground. After flipping, the module includes both the top plate and the bottom plate.

[0059] Furthermore, the 180-degree flipped three-dimensional precast concrete module 100 has two forms, with four or five sides, and is composed of a top plate and several wall bodies 110. During production, the wall bodies 110 are all perpendicular to the ground, the floor slab 120 is located on top of the wall bodies 110, and after flipping, the opening of the module faces upward, and the top plate of the module is transformed into the bottom plate.

[0060] Among them, the vertical joints between horizontally adjacent three-dimensional precast concrete modules 100 are connected by grouting with steel anchor rings, and the horizontal joints between vertically adjacent modules are connected by grouting with steel bars to achieve the coordinated force transmission of the wall bodies 110. The adjacent floor slabs 120 are lap-connected by circular steel bars 140 to ensure reliable horizontal connection of the floor slabs 120.

[0061] Preferably, when the 180-degree flipped three-dimensional precast concrete module 100 adopts the five-sided form, only the top surface is open after flipping 180 degrees, and they need to be arranged at intervals to achieve a large building space while avoiding the situation of "double-wall" connection. The horizontally adjacent three-dimensional precast concrete modules 100 are connected by beam and slab. The beam and slab can be in precast form, can be set independently, or can be designed as an integrated precast component of beam and slab.

[0062] It should be noted that the wall body 110 adopts a fully precast form, with door and window openings left on its surface, steel bars protruding from the top surface, pre-embedded metal corrugated pipes set at the bottom, and pre-embedded threaded sleeves 130 set on the side.

[0063] Furthermore, a mortar bedding layer is left between two vertically adjacent three-dimensional precast concrete modules 100, and its thickness is not less than 20 mm.

[0064] Specifically, the floor slab 120 adopts a fully precast form. When the space span is large, the floor slab 120 can adopt a closely assembled prestressed fully precast slab, and a post-cast strip is provided at the end of the floor slab 120.

[0065] Preferably, the horizontal joints and vertical joints between the wall bodies 110 are filled with high-strength grouting material to ensure reliable connection between the wall bodies 110.

[0066] During use,

[0067] See Figures 1 to 3 , a quickly assembled concrete three-dimensional precast concrete module 100 building proposed by the present invention includes several three-dimensional precast concrete modules 100 with a C-shaped plane, which can be freely combined to form functional spaces. The three-dimensional precast concrete module 100 innovatively adopts a "flipping" production method. According to different flipping angles, it can be divided into a 90-degree flipped three-dimensional precast concrete module 100 and a 180-degree flipped three-dimensional precast concrete module 100.

[0068] Refer to Figure 4a, the 90-degree flipped three-dimensional precast concrete module 100 includes five sides, consisting of a top plate, a bottom plate, and three side walls. During production, the side without a wall for the opening faces downward, and the top plate and the bottom plate are perpendicular to the ground.

[0069] See Figures 4b to 4c , the 180-degree flipped three-dimensional precast concrete module 100 includes four or five sides, consisting of a top plate and several side walls. During production, the side walls are all perpendicular to the ground, and the floor slab 120 is located on top of the side walls.

[0070] After the three-dimensional precast concrete module 100 is demolded, when the concrete strength reaches the design requirements, it is flipped 90 degrees or 180 degrees so that the positions of the floor slab 120 and the side walls meet the installation and usage requirements.

[0071] See Figures 5 to 8 , for the vertical joints between horizontally adjacent three-dimensional precast concrete modules 100, steel anchor ring grouting connection can be adopted, and for the horizontal joints between vertically adjacent three-dimensional precast concrete modules 100, steel bar slurry anchor connection can be adopted to achieve the coordinated force transfer in the horizontal and vertical directions of the side walls. The adjacent floor slabs 120 are overlapped by the circular steel bars 140 to achieve the horizontal force transfer of the slabs.

[0072] Furthermore, the width of the post-cast area of the vertical joints on the side of the wall is not less than 100 mm. The spacing of the steel anchor rings set on the side of the wall should not be greater than 600 mm, and the diameter of the longitudinal bars inside the anchor rings should not be less than 10 mm to ensure the reliable transfer of structural shear force and avoid the slippage of vertical joints.

[0073] Furthermore, circular steel bars 140 are arranged in the post-cast belt of the floor slab 120 and are lap-connected with the extended steel bars in the slab. The lap length is not less than 1.0 laE, where laE is the seismic anchorage length of the tension steel bar.

[0074] Furthermore, to ensure the construction quality of grouting, the surface of the floor slab 120 should be set with a rough surface, and the uneven depth is not less than 6 mm;

[0075] Furthermore, at the joints of the floor slab 120, two continuous slopes are formed by chamfering the bottom surface and inclining the side surface. The chamfer size of the bottom surface is not less than 10 mm × 10 mm, and the slope of the inclined surface is not less than 1:8.

[0076] In summary, by adopting the idea of modular assembly, the full precast assembly of the side walls 110 can be realized, avoiding the problems such as complex on-site connection construction and the need for temporary supports existing in the traditional precast concrete shear wall structure, and at the same time preventing the "double-wall" situation in the precast concrete modular building, so as to achieve the effects of greatly improving the on-site construction and production hoisting efficiency and reducing the comprehensive cost.

[0077] Embodiment 2

[0078] Refer to Figures 9 to 11, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an assembly method, including a building system for rapid assembly of pentahedron concrete turnover modules. The method includes the following steps:

[0079] S1: Fabricate the three-dimensional precast concrete module 100. The three-dimensional precast concrete module 100 has two production methods. One is the three-dimensional precast concrete module 100 with a 90-degree turnover, that is, the side without the wall 110 faces down during production, and the top plate and the bottom plate are perpendicular to the ground. The other is the three-dimensional precast concrete module 100 with a 180-degree turnover, that is, the walls 110 are all perpendicular to the ground during production, and the floor slab 120 is located on top of the walls 110;

[0080] S2: Turn over the three-dimensional precast concrete module 100. After demolding and waiting for the concrete strength to reach the design requirements, turn over the three-dimensional precast concrete module 100 by 90 degrees or 180 degrees to complete the module hoisting and positioning;

[0081] S3: First fix the position of one three-dimensional precast concrete module 100, then hoist another three-dimensional precast concrete module 100 to the same height as this three-dimensional precast concrete module 100. After aligning the walls 110 on both sides, connect the vertical joints between the walls 110. Subsequently, hoist and install the remaining three-dimensional precast concrete modules 100 one by one. After all the modules are installed, fill all the vertical joints with high-strength grouting material;

[0082] S4: Align the floor slab 120. The joints should be filled with polymer-modified cement mortar. Subsequently, install the circular steel bars 140 at the position of the post-cast strip at the end of the slab, and lap-connect them with the extended steel bars at the end of the slab. Finally, pour concrete to achieve the horizontal connection of the floor slab 120;

[0083] S5: Hoist the upper three-dimensional precast concrete module 100, align the walls 110 of the upper and lower three-dimensional precast concrete modules 100, and lower it vertically. Then connect the horizontal joints between the upper and lower walls 110. A mortar bedding layer should be reserved between the upper and lower three-dimensional precast concrete modules 100. After the assembly of the three-dimensional precast concrete module 100 is completed, fill all the horizontal joints with high-strength grouting material;

[0084] Repeat steps S3 - S5 to complete the assembly of all the three-dimensional precast concrete modules 100 in the building;

[0085] When the three-dimensional precast concrete module 100 is an 180-degree turnover module including four sides, the following steps are further included:

[0086] S6: Hoist the floor slab 120 of the top floor, lower it vertically to the top of the wall 110, and connect the floor slab 120 and the wall 110. After all the installations are completed, fill all the post-cast areas with concrete;

[0087] S7: The assembly of the three-dimensional precast concrete module 100 can also adopt a combination of 90-degree flipping and 180-degree flipping including four sides, that is, the three-dimensional precast concrete module 100 with 180-degree flipping is used from the first floor to the second-to-last floor to ensure that each floor of the three-dimensional precast concrete module 100 has a bottom plate, and the three-dimensional precast concrete module 100 with 90-degree flipping is used on the top floor to make the top floor have both a top plate and a bottom plate, thus avoiding the secondary assembly of the floor slab 120 and the wall 110 on the top floor;

[0088] S8: When the three-dimensional precast concrete module 100 is an 180-degree flipping module including five sides, its installation steps are the same as those of the 180-degree flipping module including four sides above. The only difference is that in order to achieve a large-space layout, the horizontally adjacent modules are connected by precast beams and precast slabs. Therefore, only step S3 needs to be replaced with step S9, which is as follows:

[0089] S9: First, fix the positions of two three-dimensional precast concrete modules 100, then lift the precast beams and precast slabs, and connect the beams and slabs to the left and right three-dimensional precast concrete modules 100, so as to achieve a large-space area. After all the three-dimensional precast concrete modules 100 and the connection structures are installed, all the post-cast areas are filled with high-strength grouting material.

[0090] In summary, by adopting the idea of modular assembly, the full precast assembly of the wall 110 can be realized, avoiding the problems existing in the traditional precast concrete shear wall structure, such as complex on-site connection construction and the need for temporary supports, and at the same time preventing the occurrence of the "double-wall" situation in the concrete modular building, so as to achieve the effect of greatly improving the on-site construction and production hoisting efficiency and reducing the comprehensive cost.

10. An assembly method, characterized in that: A building system comprising the quick assembly of pentahedral concrete flip modules according to any one of claims 1 to 9, wherein the method comprises the following steps: S1: constructing the three-dimensional precast concrete module (100), wherein the three-dimensional precast concrete module (100) includes two production methods, one is a 90-degree flip of the three-dimensional precast concrete module (100), that is, during production, the side without the wall (110) faces downward, and the top plate and the bottom plate are perpendicular to the ground; the other is a 180-degree flip of the three-dimensional precast concrete module (100), that is, during production, the wall (110) is perpendicular to the ground, and the floor slab (120) is located on the top of the wall (110); S2: turning over the three-dimensional precast concrete module (100), and after demoulding and when the concrete strength reaches the design requirement, turning over the three-dimensional precast concrete module (100) by 90 degrees or 180 degrees to complete the module hoisting in place; S3: first fix the position of one of the three-dimensional precast concrete modules (100), then hoist another of the three-dimensional precast concrete modules (100) to the same height as the three-dimensional precast concrete module (100), align the walls (110) on both sides, and then connect the vertical joints between the walls (110), then hoist and install the remaining three-dimensional precast concrete modules (100) one by one, and after all the modules are installed, fill all the vertical joints with high-strength grouting material; S4: Align the floor slab (120), fill the joints with polymer modified cement mortar, then install the annular steel bar (140) at the post-casting strip at the end of the slab, and overlap and connect it with the protruding steel bars at the end of the slab, and finally pour concrete to achieve horizontal connection of the floor slab (120); S5: lifting the three-dimensional precast concrete module (100) of the upper layer, aligning the walls (110) of the three-dimensional precast concrete modules (100) of the upper and lower layers, and lowering them vertically, and then connecting the horizontal joints between the upper and lower walls (110), a grouting layer should be reserved between the three-dimensional precast concrete modules (100) of the upper and lower layers, and after the three-dimensional precast concrete modules (100) are assembled, all horizontal joints are filled with high-strength grouting material; Repeat steps S3 to S5 to complete the assembly of the three-dimensional prefabricated concrete modules (100) of the entire building; When the three-dimensional prefabricated concrete module (100) is a 180-degree flip module with four sides, it also includes the following steps: S6: lifting the floor slab (120) on the top floor, vertically lowering it to the top of the wall (110), connecting the floor slab (120) and the wall (110), and after all installations are completed, filling all post-casting areas with concrete; S7: The assembly of the three-dimensional precast concrete module (100) may also be performed by a combination of a 90-degree flip and a 180-degree flip involving four sides, that is, the three-dimensional precast concrete module (100) flipped 180 degrees is used from the first floor to the second to last floor to ensure that each layer of the three-dimensional precast concrete module (100) has a bottom plate, and the top floor uses the three-dimensional precast concrete module (100) flipped 90 degrees, so that the top floor contains both the top plate and the bottom plate, thereby avoiding secondary assembly of the floor slab (120) and the wall (110) on the top floor; S8: When the three-dimensional precast concrete module (100) is a 180-degree flip module with five sides, its installation steps are the same as those of the above-mentioned 180-degree flip module with four sides, the only difference being that in order to achieve large space arrangement, the horizontally adjacent modules are connected by precast beams and precast panels, so it is only necessary to replace step S3 with step S9, which is as follows: S9: first fix the positions of the two three-dimensional precast concrete modules (100), then hoist the precast beams and precast panels, and connect the beams and panels to the left and right three-dimensional precast concrete modules (100), so as to realize a large space area. After all the three-dimensional precast concrete modules (100) and the connection structure are installed, all post-casting areas are filled with high-strength grouting material.
