Description

Technical Field

[0001] This utility model belongs to the field of building node fixing technology, specifically relating to a modular combined housing building node fixing structure. Background Technology

[0002] In the construction of modular housing, high-strength bolts are often used to connect nodes. Each node requires tightening a large number of bolts, which leads to complicated procedures and low work efficiency. Moreover, during long-term use, bolts are prone to loosening due to vibration loads such as wind loads and earthquakes, which may cause structural safety hazards. While pin-type connections simplify the installation process, their insufficient tensile strength results in weak node connection rigidity, making it difficult to effectively resist vertical pull-out forces and horizontal shear forces, which seriously affects the overall stability of the structure.

[0003] Therefore, this utility model proposes a modular combined housing building node fixing structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a modular combined housing building node fixing structure that can solve the above-mentioned technical problems.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1-4 As shown, a modular combined housing building node fixing structure includes a shell 1 and a locking mechanism 5 disposed on the shell 1. The locking mechanism 5 is disposed on a horizontal plate 4, and the horizontal plate 4 is fixed to the inner side of the shell 1. A guide cylinder 6 is detachably installed on the surface of the shell 1. The guide cylinder 6 is provided with a docking mechanism that engages with the locking mechanism 5. An adjustment mechanism for opposing and opening the locking mechanism 5 is provided inside the shell 1. The docking mechanism includes a tensile shaft 7 and a tensile folding plate 73. There are two tensile shafts 7, and the upper ends of both shafts are fixed on the tensile folding plate 73. A guide cone 71 and an insertion cone 72 are fixed on the tensile shaft 7. Both the guide cone 71 and the insertion cone 72 are inserted into the guide cylinder 6. The guide cone 71 is located at the lower end of the tensile shaft 7 and protrudes from the lower side of the guide cylinder 6. An overlapping ring 72a is fixed on the insertion cone 72. The overlapping ring 72a overlaps with the face ring 62 fixed at the upper end of the guide cylinder 6. Two guide tubes 6 are provided, and both are fixed on the top cover plate 61. The top cover plate 61 is detachably installed at the surface opening of the housing 1. The guide tube 6 is sleeved with the sleeve hole 41 opened on the horizontal plate 4, and the end extends into the inside of the housing 1.

[0017] As an optional implementation, the locking mechanism 5 includes two opposing sliders 51 and two tension springs 55. The two opposing sliders 51 are both disposed inside the housing 1 and are horizontally positioned on the bottom surface of the horizontal plate 4. The bottom surfaces of the opposing sides of the two opposing sliders 51 are set as inclined surfaces, and the opposing sides of the two opposing sliders 51 are provided with open locking slots 52. The locking slots 52 are slidably engaged with the anti-tension shaft 7. Ear plates 51a are fixed on both sides of the bottom surface of the two opposing sliders 51. The two sides of the tension springs 55 are respectively hooked onto the two horizontally corresponding ear plates 51a. In this way, the two opposing sliders 51 can be pulled relative to each other by means of the tension springs 55, which facilitates the relative movement of the two opposing sliders 51 during subsequent disassembly and separation, thereby releasing the locking constraint on the guide cone 71.

[0018] Furthermore, one of the opposing sliders 51 has a misalignment portion 53 on its surface, and the other opposing slider 51 has two side plates 54 on its side. Both side plates 54 overlap the misalignment portion 53 and slide and engage with the misalignment grooves 53a on one of the sliders on both sides of the misalignment portion 53. In this way, when the two opposing sliders 51 are on the same plane, the vertical misalignment of the side plates 54 and the misalignment portion 53 can ensure the relative and opposite movement of the two opposing sliders 51.

[0019] See attached document Figure 2 and attached Figure 4 The housing 1 is provided with two suspension bolts 56. The two suspension bolts 56 are respectively set on the longitudinal opposite side of the upward moving through hole 42 opened on the horizontal plate 4. The suspension bolts 56 pass through the first sliding hole 43 and the second sliding hole 54a and are threadedly connected to the threaded hole opened on the surface of the misaligned part 53 of one of the opposing sliders 51. This makes it easy to slide the two opposing sliders 51 on the horizontal plate 4, so that when the opposing sliders 51 move in opposite directions, they can cooperate with the horizontal plate 4 to vertically lock and restrict the guide cone 71. Two first sliding holes 43 are provided, both of which are opened on the horizontal plate 4 and located on the longitudinal opposite side of the upward sliding hole 42. Two second sliding holes 54a are provided, and the two holes are respectively opened on the two side plates 54.

[0020] See attached document Figure 3The adjustment mechanism includes a support block 8, an arch bridge frame 9, and a threaded rod 11. The arch bridge frame 9 is detachably installed on the bottom surface of the support block 8. A spacer plate is provided on the upper side of the support block 8, and the spacer plate is located between two opposing sliders 51 and is fitted into the upward moving through hole 42. The upward moving through hole 42 is clearance-fitted with the enlarged end of the support block 8. In this way, when the support block 8 moves upward, the spacer plate is used for upward guidance, so that the support block 8 can move the two opposing sliders 51 in opposite directions, thereby locking and restricting the guide cone 71.

[0021] Furthermore, the lower end of the threaded rod 11 is rotatably mounted on the bottom cover plate 12 via a bearing. The bottom cover plate 12 is detachably mounted on the bottom opening of the housing 1. A threaded sleeve 10 is threadedly connected to the threaded rod 11. The threaded sleeve 10 is mounted on the lower side of the arch bridge frame 9. An internal hexagonal hole is opened on the bottom surface of the threaded rod 11. This allows the arch bridge frame 9 and the support block 8 to move up and down and be adjusted through the threaded sleeve 10 when the threaded rod 11 rotates.

[0022] Furthermore, a panel 2 is detachably connected to the side opening of the shell 1. Multiple reinforcing bars 3 are fixed to the opposite sides of the panel 2 and the shell 1. This allows the shell 1 to be connected and fixed to the reinforcing bars on the module before the module is precast and poured, thereby improving the fixing strength of the shell 1 after it is poured into the module.

[0023] Using the above structure, the shell 1 is first fixed to the steel reinforcement skeleton of the module component and cast in the factory prefabrication stage to form a pre-embedded node. During on-site installation, the top cover plate 61 and its guide tube 6 assembly are first positioned and installed at the opening on the surface of the shell 1 through the sleeve hole 41 and the horizontal plate 4. Then, the tensile shaft 7 assembly of the docking mechanism is vertically inserted through the guide tube 6. The guide cone 71 at its lower end first contacts the inclined surface of the opposing slider 51. During the insertion process, it passes through the opposite sides of the two opposing sliders 51. After the insertion cone 72 has completely passed through, the overlapping ring 72a overlaps with the face ring 62 to complete the axial positioning and achieve radial limiting. During insertion, the spring pulls the two opposing sliders 51 to remain in a relative state, while the guide cone 71 penetrates into the housing 1 and is vertically misaligned with the two opposing sliders 51. Then, the tool is used to rotate the internal hexagonal hole at the bottom of the threaded rod 11, which drives the arch bridge frame 9 and the support block 8 to move upward through the threaded sleeve 10. The spacer plate of the support block 8 pushes the two opposing sliders 51 to move in opposite directions, so that the bayonet 52 tightly locks the anti-tensile shaft 7 to form a rigid connection. During disassembly, the module unit can be quickly separated by reversing the operation. The entire process only requires a single-point adjustment to complete the locking and releasing, achieving a unity of efficient installation and reliable connection.
