Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and more specifically to a beam-column connection node structure for assembled buildings. Background Art

[0002] The beam-column connection node structure for prefabricated buildings is a key structural part used to connect beams and columns in prefabricated buildings. It combines prefabricated beam components with prefabricated or cast-in-place column components according to design requirements to form a stable connection between the two, thereby jointly bearing the load borne by the building structure.

[0003] The connecting plates at the transverse and longitudinal joints of the beam-column connection node structure of traditional prefabricated buildings are mainly directly fixed together by bolts, and only rely on the shear resistance of the bolts and the bending resistance of the connecting plates to transmit the forces at the beam ends and column ends. For some large-span and heavy-loaded building structures, the shear and bending resistance of their connection nodes may not meet the design requirements. When the beam ends are subjected to large bending moments and shear forces, the bolts are prone to shearing and the connecting plates may experience local buckling and deformation, thereby endangering the safety of the entire structure. Under repeated loads, such as wind loads, earthquakes, and vibrations in daily use, the bolts will be subjected to constantly changing stresses and are prone to fatigue damage. Once fatigue fracture occurs in the bolts, the connection node will instantly lose part or all of its bearing capacity, which can easily cause local damage to the structure or even overall collapse. Utility Model Content

[0006] Furthermore, the positioning assembly includes a fixed seat fixedly welded inside the fixed plate, a slide groove is provided inside the fixed seat, a slide plate is sealingly and slidably connected inside the slide groove, a stop plate is fixedly connected to the surface of the slide plate, a sealing groove and a connecting groove are provided inside the fixed seat, the sealing groove is sealingly and slidably connected to the sealing plate, a positioning block is fixedly connected to the top of the sealing plate, a clamping groove is provided on the side of the positioning block, a limiting groove is provided inside the fixed seat, a clamping block is slidingly connected inside the limiting groove, and a silicone block is fixedly connected inside the limiting groove.

[0007] Furthermore, the surface of the clamping block abuts against the surface of the positioning block, and the clamping block matches the clamping slot.

[0008] Furthermore, the interior of the slide groove is connected with the interior of the sealing groove through a connecting groove, and sealing rings are fixedly installed on the outer surfaces of the slide plate and the sealing plate.

[0009] Furthermore, the positioning block, the through hole and the positioning hole match each other, and the length of the positioning hole is equal to the length of the through hole.

[0010] Furthermore, the surface of the abutment plate abuts against the surface of the side plate, and the distance from the top of the side plate to the upper baffle plate is equal to the distance from the bottom of the side plate to the lower baffle plate and is equal to the thickness of the insert plate.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model provides a positioning assembly. When the fixing plate and the side plate are assembled together by bolts, the side plate abuts against the abutment plate, which can drive the abutment plate to slide, pressurize the inside of the sealing groove, and make the surface of the positioning block pass through the perforation and be inserted into the inside of the positioning hole, thereby adding an additional force transmission path. When the building structure is subjected to vertical load, the force can be effectively transmitted and dispersed through the positioning assembly, avoiding excessive concentration of stress at the bolt connection position, so that the entire beam-column connection node can be subjected to force in a coordinated manner, thereby improving the ability of the overall structure to resist deformation and damage, and making the structural system of the prefabricated building more stable and reliable.

[0013] 2. The utility model can position the positioning block by providing a clamping structure of the clamping block and the clamping groove, thereby avoiding the disadvantages of poor air tightness inside the sealing groove during long-term use and loss of traction after the positioning block is retracted into the sealing groove, thereby enhancing stability.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0022] Figure 1-Figure 6 It is the best embodiment of the utility model, and the following Figure 1-Figure 6 The utility model is further described.

[0024] In this embodiment, by providing the plug plate 7, after the plug plate 7 is plugged into the outside of the side plate 5, due to the mutual abutment, the longitudinal supporting force of the lateral supporting structure can be increased, thereby enhancing the stability.

[0025] Specifically, the positioning assembly 9 includes a fixed seat 91 fixedly welded inside the fixed plate 6, a slide groove 92 is opened inside the fixed seat 91, the slide groove 92 is internally sealed and slidably connected to a slide plate 93, the surface of the slide plate 93 is fixedly connected to a stop plate 94, a sealing groove 95 and a connecting groove 96 are opened inside the fixed seat 91, the sealing groove 95 is internally sealed and slidably connected to a sealing plate 97, a positioning block 98 is fixedly connected to the top of the sealing plate 97, a card slot 99 is opened on the side of the positioning block 98, a limiting groove 910 is opened inside the fixed seat 91, a card block 912 is slidably connected to the limiting groove 910, and a silicone block 911 is fixedly connected to the limiting groove 910.

[0026] In this embodiment, by setting the positioning component 9, when the fixing plate 6 and the side plate 5 are assembled together by bolts, the side plate 5 can abut against the abutment plate 94 to drive the abutment plate 94 to slide, thereby pressurizing the inside of the sealing groove 95, and making the surface of the positioning block 98 pass through the through hole 71 and be inserted into the inside of the positioning hole 10, thereby adding an additional force transmission path. When the building structure is subjected to vertical load, the force can be effectively transmitted and dispersed through the positioning component 9, avoiding excessive stress concentration at the bolt connection position, so that the entire beam-column connection node can be subjected to force synergistically, thereby improving the ability of the overall structure to resist deformation and damage, and making the structural system of the prefabricated building more stable and reliable.

[0027] Specifically, the surface of the clamping block 912 abuts against the surface of the positioning block 98 , and the clamping block 912 matches the clamping slot 99 .

[0028] In this embodiment, by providing a clamping structure of the clamping block 912 and the clamping groove 99, the positioning block 98 can be positioned, thereby avoiding the disadvantage that the air tightness inside the sealing groove 95 deteriorates during long-term use and the positioning block 98 loses traction after retracting into the sealing groove 95, thereby enhancing stability.

[0029] Specifically, the interior of the slide groove 92 is connected to the interior of the sealing groove 95 through the connecting groove 96 , and sealing rings are fixedly mounted on the outer surfaces of the slide plate 93 and the sealing plate 97 .

[0030] In this embodiment, by providing a sealing ring, the sealing performance of the slide groove 92, the connecting groove 96 and the sealing groove 95 can be enhanced.

[0031] Specifically, the positioning block 98 , the through hole 71 and the positioning hole 10 match each other, and the length of the positioning hole 10 is equal to the length of the through hole 71 .

[0032] In this embodiment, since the length of the positioning hole 10 is equal to the length of the through hole 71, when the positioning block 98 is inserted into the positioning hole 10, the gap at the connection can be minimized to enhance the stability of the connection.

[0033] Specifically, the surface of the abutment plate 94 abuts against the surface of the side plate 5 , and the distance from the top of the side plate 5 to the upper baffle 4 is equal to the distance from the bottom of the side plate 5 to the lower baffle 3 and is equal to the thickness of the insert plate 7 .

[0034] In this embodiment, when the inserting plate 7 is inserted into the side plate 5 and the bottom, the friction between the inserting plate 7 and the lower baffle plate 3 and the upper baffle plate 4 can be increased, thereby enhancing the firmness.

[0035] The working principle and use process of the utility model are as follows: during assembly, the fixing plate 6 is brought close to the side plate 5, and the bolts are passed through the corresponding insertion holes on the surfaces of the side plate 5 and the fixing plate 6. Then, by turning the nuts on the bolts, the surface of the fixing plate 6 is gradually brought close to the surface of the side plate 5. At this time, the two plug plates 7 are respectively plugged into the connection between the side plate 5 and the upper baffle plate 4 and the side plate 5 and the lower baffle plate 3. At the same time, the surface of the push plate 94 is against the surface of the side plate 5, and the push plate 94 drives the slide plate 93 to slide inside the slide groove 92. At this time, the inside of the slide groove 92 is in a pressurized state, and the inside of the sealing groove 95 is in a pressurized state through the connecting groove 96, and the sealing plate 97 drives the positioning block 98 to slide upward , and the positioning block 98 passes through the through hole 71 until the surface of the clamping block 912 is clamped in the clamping groove 99, and the outer surface of the positioning block 98 is inserted into the inside of the positioning hole 10. At this time, the surfaces of the fixing plate 6 and the side plate 5 are completely fitted and fixed together by tension bolts. The bolts are assembled and plugged in for positioning, which adds an additional force transmission path. When the building structure is subjected to vertical load, the force can be effectively transmitted and dispersed through the positioning assembly 9, avoiding excessive stress concentration at the bolt connection position, so that the entire beam-column connection node can be synergistically stressed, thereby improving the ability of the overall structure to resist deformation and damage, and making the structural system of the prefabricated building more stable and reliable.
