Description
Technical Field
[0001] This invention relates to the field of prefabricated building technology, and in particular to a modular assembly device for umbrella-shaped structural nodes in prefabricated buildings. Background Technology
[0002] In the field of prefabricated buildings, the structural form of beam-column joints plays a crucial role in the construction efficiency, quality, and cost control of buildings.
[0003] In traditional prefabricated buildings, beam-column joints are typically cross-shaped. This structure presents several problems in actual construction: First, the connection method of cross-shaped joints is complex, requiring precise positioning and frequent on-site welding or bolting operations, making construction difficult. Second, the assembly process of cross-shaped joints is time-consuming and demands a high level of technical skill from construction workers, resulting in low construction efficiency. Furthermore, errors are prone to occur during the connection process of cross-shaped joints, affecting the overall stability and safety of the structure, and making it difficult to guarantee the quality of the process. At the same time, cross-shaped joints have low material utilization rates, easily leading to resource waste and increasing construction costs. Summary of the Invention
[0004] To overcome the aforementioned drawbacks, the present invention provides a modular assembly device for umbrella-shaped structural nodes in prefabricated buildings.
[0005] Technical Solution: A modular assembly device for umbrella-shaped structural nodes in prefabricated buildings includes support columns, connecting beams, diagonal braces, connecting rings, and mounting rings. The support columns, as the main body supporting the entire structure, are vertically and evenly spaced on the building ground. The tops of the support columns are connected by connecting beams to form horizontal and longitudinal beams, which constitute a grid structure. The connection points between the connecting beams and the support columns serve as the connection fulcrums of each grid, and the connecting beams and support columns are detachably connected. Every four diagonal braces and connecting rings cooperate to form an umbrella-shaped structure. In the grid structure formed by the support columns and connecting beams, the umbrella-shaped structures are spaced apart. The diagonal braces are fixedly connected to the top of the support columns in an inclined manner. Connecting rings are assembled between the inner sides of every four diagonal braces. The connecting rings are plugged into the diagonal braces, and mounting rings are installed on the top of the connecting rings. Reinforcing bars are inserted circumferentially into the mounting rings.
[0006] In one embodiment, the device further includes a top block, a groove block, a push rod, a double cone block, a locking rod, and a locking spring. Four top blocks are spaced apart on the lower outer side of the connecting ring. A groove block is connected to the inner side of the bottom of the diagonal brace. The groove block is fitted onto the outer side of the top block, and the two are locked together on both sides. Four push rods are spaced apart circumferentially at the bottom of the mounting ring. A double cone block is slidably connected inside the top block. The double cone block extends through into the interior of the connecting ring. The inner and outer sides of the double cone block are both inclined structures, and the bottom surface of the push rod is also inclined. The bottom surface of the push rod contacts the inclined structure of the inner side of the double cone block. A pair of locking rods are slidably connected to the top block near the side of the double cone block. The pair of locking rods are distributed on both sides of the double cone block. A locking spring is connected between the locking rod and the interior of the top block. The end of the locking rod near the double cone block is an arc surface and contacts the outer side of the double cone block. The locking rod penetrates through the top block. Holes are opened on both sides of the groove block at positions aligned with the locking rods, and the locking rods are locked together with the holes.
[0007] In one embodiment, the device further includes insert rods, plugs, and buffer springs. Four sets of insert rods are circumferentially spaced at the bottom of the mounting ring, with two insert rods in each set. The insert rods and push rods are staggered. Plugs are slidably connected to both sides of the area inside the connecting ring at the inner end of the diagonal brace. The plugs are aligned with the insert rods, and a buffer spring is connected between the plug and the diagonal brace.
[0008] In one embodiment, the connecting beam adopts a combination structure of double-groove base beam, single-groove wing plate and U-shaped locking clip to realize the connection between multiple connecting beams and the connecting beam and the support column. In the grid structure composed of connecting beams and support columns, each connecting beam is connected to a double-groove base beam, a single-groove wing plate or a U-shaped locking clip at both ends, and the components connected to both ends of a single connecting beam are the same. In the grid structure, when constructing a complete cross structure, one connecting beam with a double-groove base beam, two connecting beams with single-groove wing plates and one connecting beam with a U-shaped locking clip are required. The double-groove base beam, single-groove wing plate and U-shaped locking clip are all inserted into the support column for connection.
[0009] In one embodiment, the opening width of the U-shaped locking clip is equal to the distance between the opposing surfaces of the two single-groove wing plates, and the arm length of the U-shaped locking clip is equal to the groove depth of the single-groove wing plate.
[0010] In one embodiment, the device further includes a reinforcement member, a compression spring, and a positioning rod. The reinforcement member is slidably connected to the inner side of the upper end of the support column. A compression spring is connected between the bottom of the reinforcement member and the inside of the support column. A positioning rod is connected to the top of the reinforcement member. A positioning groove is provided in the middle of the double-groove base beam. The positioning groove and the positioning rod are engaged. One side of the reinforcement member is provided with an inclined surface. A U-shaped locking clip is in contact with the inclined surface of the reinforcement member.
[0011] In one embodiment, two mounting holes are provided at both ends of the connecting beam near the connecting support point.
[0012] In one embodiment, the support column, connecting beam, diagonal brace, connecting ring, and mounting ring are all made of high-strength steel.
[0013] The beneficial effects are: 1. The umbrella-shaped structure formed by the combination of diagonal braces and connecting rings creates a stable spatial force system. The loads are distributed at intervals in the grid structure formed by the supporting columns and connecting beams, which can effectively disperse and transfer the loads, enhance the overall strength and deformation resistance of the structure, and improve the seismic and wind resistance performance of the building structure.
[0014] 2. The supporting columns, as the main supporting structures, are evenly distributed vertically and can effectively transfer the building load. Through the coordinated work of steel bars and concrete, they jointly bear and transfer various loads of the superstructure, ensuring the overall stability of the building.
[0015] 3. Through structures such as top blocks, groove blocks, push rods, double cone blocks, clamping rods, and clamping springs, a stable connection between the diagonal brace and the support column is achieved; the connection stability is further enhanced by the cooperation of insert rods, plugs, and buffer springs; the connecting beam adopts a connection method of double-groove base beam, single-groove wing plate, and U-shaped locking clamp, combined with reinforcement parts, compression springs, and positioning rods, which improves the firmness of the connection support points between the connecting beams and ensures the safety of the building structure.

Detailed Implementation
[0036] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0037] Example: A modular assembly device for umbrella-shaped structural nodes in prefabricated buildings, such as... Figures 1-4 , Figure 13 and Figure 15 As shown, the structure includes support columns 1, connecting beams 101, diagonal braces 102, connecting rings 103, and mounting rings 201. The support columns 1, as the main support of the entire structure, are vertically and evenly spaced on the building ground, primarily functioning to transfer the building's load. The tops of the support columns 1 are connected by connecting beams 101, forming horizontal and vertical beams that constitute a grid structure. The connection points between the connecting beams 101 and the support columns 1 serve as the connecting fulcrums for each grid. The connecting beams 101 and support columns 1 are detachably connected. Two mounting holes 6 are provided at both ends of the connecting beams 101 near the connecting fulcrums for installing screws. The screw connection securely connects the connecting beams 101 and support columns 1. Every four diagonal braces 102, together with the connecting rings 103, form an umbrella-shaped structure. In the grid structure, umbrella-shaped structures are distributed at intervals. The diagonal braces 102 are fixedly connected to the top of the support column 1 in an inclined manner. A connecting ring 103 is assembled between the inner sides of every four diagonal braces 102. The connecting ring 103 is plugged into the diagonal brace 102. An installation ring 201 is installed on the top of the connecting ring 103. The reinforcing bars 104 are inserted into the installation ring 201 in a circumferential manner. The installation ring 201 disperses the reinforcing bars 104 at intervals to bear the load. A cement structure is poured on the reinforcing bars 104 so that the reinforcing bars 104 and the concrete work together to bear the load from the superstructure, including the building's self-weight, floor load, and the vertical component of horizontal loads such as wind load and seismic load, and transfer these loads to the foundation. The support column 1, connecting beam 101, diagonal braces 102, connecting ring 103 and installation ring 201 are all made of high-strength steel to ensure the strength and stability of the structure.
[0038] like Figures 5-9As shown, it also includes a top block 202, a groove block 203, a push rod 204, a double cone block 205, a locking rod 206, and a locking spring 207. Four top blocks 202 are spaced apart on the lower outer side of the connecting ring 103. A groove block 203 is connected to the inner bottom of the diagonal brace 102, and the groove block 203 is fitted onto the outer side of the top block 202, with both sides engaging in a locking fit. Four push rods 204 are spaced apart circumferentially at the bottom of the mounting ring 201. A double cone block 205 is slidably connected inside the top block 202, extending through into the interior of the connecting ring 103. The bottom surface of the push rod 204 contacts the inclined structure of the inner side of the double cone block 205. Both the inner and outer sides of the double cone block 205 are inclined structures, and the bottom surface of the push rod 204 is also inclined to facilitate contact. When the mounting ring 201 is inserted into the inner side of the connecting ring 103 from top to bottom, the push rod 204 moves downward, pushing the double cone block 205 outward. The top block 202 is slidably connected to a pair of locking rods 206 on one side of the double cone block 205. The pair of locking rods 206 are distributed on both sides of the double cone block 205. A locking spring 207 is connected between the locking rods 206 and the inside of the top block 202. The end of the locking rod 206 that is close to the double cone block 205 is an arc surface and contacts the outer surface of the double cone block 205. The locking rod 206 passes through the top block 202. Holes are opened on both sides of the groove block 203 at positions aligned with the locking rods 206. The locking rods 206 engage with the holes. When the double cone block 205 is pushed outward by the push rod 204, its inner surface will simultaneously squeeze the locking rod 206 to move outward. The locking spring 207 is compressed accordingly. At this time, the locking rod 206 engages with the hole on the groove block 203, realizing a stable connection between the top block 202 and the groove block 203, thereby improving the connection stability between the diagonal brace 102 and the support column 1.
[0039] like Figures 10-11 As shown, it also includes insert rods 301, plugs 302, and buffer springs 303. Four sets of insert rods 301 are welded circumferentially at intervals at the bottom of the mounting ring 201. Each set of insert rods 301 consists of two rods. The insert rods 301 and push rods 204 are staggered. Plugs 302 are slidably connected to both sides of the area where the inner end of the diagonal brace 102 is inserted into the inside of the connecting ring 103. The plugs 302 are aligned with the insert rods 301. A buffer spring 303 is connected between the plugs 302 and the diagonal brace 102. When the mounting ring 201 is inserted into the inner side of the connecting ring 103 from top to bottom, the insert rods 301 move synchronously with the mounting ring 201. The insert rods 301 have a U-shaped structure and will be inserted into the plugs 302. The buffer spring 303 plays a buffering role. After the insert rods 301 and plugs 302 are engaged, the stability of the connection between the diagonal brace 102 and the support column 1 can be further enhanced.
[0040] like Figures 13-19As shown, the connecting beam 101 adopts a combined structure of a double-groove base beam 401, a single-groove flange 402, and a U-shaped locking clip 403 to realize the connection between multiple connecting beams 101 and the connecting beams 101 and the supporting column 1. In the grid structure formed by the connecting beams 101 and the supporting column 1, each connecting beam 101 is connected to the double-groove base beam 401, the single-groove flange 402, or the U-shaped locking clip 403 at both ends by bolts, and the components connected to both ends of a single connecting beam 101 are the same, thus constructing a complete grid structure. When constructing a cross structure, a connecting beam 101 with a double-groove base beam 401, two connecting beams 101 with single-groove flanges 402, and a connecting beam 101 with a U-shaped locking clip 403 are required. The double-groove base beam 401, single-groove flanges 402, and U-shaped locking clip 403 are all inserted into the support column 1 for connection. The opening width of the U-shaped locking clip 403 is equal to the distance between the opposite faces of the two single-groove flanges 402. First, the connecting beam 101 with the double-groove base beam 401 is used as the basic support. Insert the component into the support column 1. Then, align the two connecting beams 101 with single-groove flanges 402 with the double-groove base beam 401, so that the grooves of the single-groove flanges 402 are aligned with the grooves on both sides of the double-groove base beam 401, and push them inward along the grooves until the single-groove flanges 402 are completely embedded in the grooves of the double-groove base beam 401, thus completing the initial assembly. Finally, face the opening of the U-shaped locking clip 403 toward the opposite side of the two single-groove flanges 402, and snap the two sides of the U-shaped locking clip 403 into the corresponding single-groove flanges 402. In the groove of the wing plate 402, since the arm length of the U-shaped locking clip 403 is equal to the groove depth of the single wing plate 402, it is ensured that the U-shaped locking clip 403 can be accurately inserted into the groove of the single wing plate 402 and achieve a firm lock. Thus, the double-groove base beam 401, the single-groove wing plate 402 and the U-shaped locking clip 403 are successfully connected into a stable whole structure through the precise groove and tenon cooperation. In the entire assembly system, the height can be stacked according to the building requirements and the number of extended grid structures to form a closed structure.
[0041] like Figure 12 and Figures 15-19As shown, it also includes a reinforcing member 501, a compression spring 502, and a positioning rod 503. The reinforcing member 501 is slidably connected to the inner side of the upper end of the support column 1. A compression spring 502 is connected between the bottom of the reinforcing member 501 and the inside of the support column 1. The positioning rod 503 is integrally formed and connected to the top of the reinforcing member 501. A positioning groove 504 is opened in the middle of the double-groove base beam 401. The positioning groove 504 and the positioning rod 503 are engaged. One side of the reinforcing member 501 is provided with an inclined surface. During the installation of the connecting beam 101, when the double-groove base beam 401 is installed, the reinforcing member 501 is inclined. After the installation of the trough base beam 401 and the single-trough wing plate 402 is completed, the positioning groove 504 on the double-trough base beam 401 is aligned with the positioning rod 503. When the U-shaped locking clip 403 is finally inserted, the U-shaped locking clip 403 contacts the inclined surface of the reinforcement 501, pushing the reinforcement 501 to move downward. The compression spring 502 is compressed, and the positioning rod 503 moves downward and engages with the positioning groove 504, thereby making the double-trough base beam 401 firmly inserted into the support column 1, effectively improving the firmness of the connection fulcrum between the connecting beams 101.
