Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings and relates to a prefabricated exterior wall connection node, specifically a prefabricated exterior wall connection node using a scissor-type adjustment device and a construction method thereof. Background Art

[0002] Prefabricated buildings, with their advantages of high prefabrication, convenient construction, and manageable construction schedules, have become a mainstream trend in the development of industrialized green buildings. The core technology lies in the reliable design of component connection nodes. The connection system between exterior walls and structural beams, a crucial component of prefabricated buildings, typically utilizes embedded-welded composite joints. These consist of embedded components within the wall and welded connectors at the beam ends, secured with bolts for integrated installation.

[0003] However, in engineering practice, traditional embedded-welded composite joints often suffer from insufficient positioning accuracy, leading to embedded component offset and weld deformation, which in turn causes screw hole misalignment and component misalignment. Furthermore, the wide variety of complex and irregular building joint types makes standardized adaptation of traditional joints difficult. While current passive adjustment measures such as hole expansion and padding can temporarily resolve installation issues, they can easily lead to stress concentration in the joint area, affecting the structure's force transmission performance and preventing precise control. This not only weakens structural safety but also restricts the universal development of the joint system. Summary of the Invention

[0004] In view of this, the present invention aims to propose an assembled exterior wall connection node and a construction method thereof using a shear-type adjustment device, so as to solve the problems of screw hole misalignment and component misalignment during actual construction due to processing errors in traditional embedded-welded composite nodes, optimize the adverse effects of commonly used passive adjustment measures on structural safety and industrialization level, and effectively improve the versatility of the node.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: an assembled exterior wall connection node using a scissor-type adjustment device, comprising a connecting beam, a steel bar group, embedded parts, connecting parts, a horizontal screw assembly, a vertical stud assembly, a scissor-type adjustment device and a fixed base, wherein the embedded parts are connected to the exterior wall through the steel bar group, the embedded parts are connected to the connecting parts through the horizontal screw assembly, the connecting parts are connected to the scissor-type adjustment device through the vertical stud assembly, and the fixed base connects the scissor-type adjustment device and the connecting beam.

[0006] Furthermore, the embedded part includes a main body, an embedded plate, a T-shaped slide and a connecting ear plate. The embedded plate is arranged on the inner side of the main body. Some steel bars in the steel bar group pass through the openings of the embedded plate, and the remaining steel bars are welded to the edges on both sides of the embedded plate. A T-shaped slide is arranged at the center of the outer side of the embedded part, and connecting ear plates with openings are arranged at both ends. A certain distance is set between the T-shaped slide and the connecting ear plate.

[0007] Furthermore, the connecting part includes a side plate, a bottom plate and two rib plates, the side plate and the two rib plates are fixed on the bottom plate, the two rib plates are perpendicular to the side plate, the rib plates are opened with holes, the position and size of the holes correspond to the connecting ear plates of the embedded parts; a hole is opened in the center of the bottom plate, and a T-shaped slider is provided on the outside of the side plate, the size of which corresponds to the T-shaped slot; the width of the side plate is smaller than the distance between the T-shaped slot and the connecting ear plate.

[0008] Furthermore, the horizontal screw assembly includes a horizontal adjustment screw, a horizontal adjustment nut and a fixing nut. The horizontal adjustment screw passes through the connecting ear plate opening of the embedded part and the rib plate opening of the connecting part. The horizontal adjustment nuts are arranged on both sides of the rib plate for adjusting the horizontal position of the exterior wall. The fixing nuts are arranged on both sides of the connecting ear plate for fixing the horizontal adjustment screw.

[0009] Furthermore, the vertical stud assembly includes a vertical adjustment stud and a vertical adjustment nut. The vertical adjustment stud passes through the bottom plate opening of the connector, and the vertical adjustment nut is arranged on the inner side of the bottom plate of the connector to adjust the vertical position of the exterior wall.

[0010] Furthermore, the scissor-type adjustment device includes a core sliding base plate, a number of springs, an end sliding base plate, a longitudinal adjustment nut, a number of hinge supports, a number of hinge rod groups and a number of rubber pads. A vertical screw hole is opened in the center of the core sliding base plate, and the size corresponds to the vertical stud assembly. Sliders are set on both sides of the core sliding base plate and the end sliding base plate, and a number of through circular holes are opened in the longitudinal direction; a number of springs are connected between the core sliding base plate and the end sliding base plate, and the connection position is at the through circular hole, which is always in a compressed state. The longitudinal adjustment nut is set on the outside of the end sliding base plate, and a number of hinge supports are set on the upper surface of the core sliding base plate and the inner side of the end sliding base plate. A number of hinge rod groups are connected through the hinge supports, and rubber pads are set at the hinge position of the hinge rod.

[0011] Furthermore, a slide groove is set inside the fixed base, baffles are welded at the front and rear, and several longitudinal adjustment screws are welded between the two baffles.

The residual stress generated is small and has no adverse effect on structural safety.

[0013] 2. The prefabricated exterior wall connection node of the present invention can increase the adjustment range when applied to complex and irregular building structures. By adjusting the exterior wall position in a large range of directions with high precision, the number of node types can be reduced. The node has high versatility and can avoid production design problems caused by too many node types.

[0014] 3. The arrangement of the slide groove and slider described in the present invention can increase the force transmission paths between the various components of the node, reduce stress concentration, avoid the safety issues that may arise when only using screws to transmit force, and improve structural redundancy. In addition, the arrangement of multiple force transmission paths plus springs and rubber pads can effectively improve the seismic and wind resistance of the node.

[0015] 4. The setting of the limit bolts described in the present invention can provide secondary fixation for the position of the outer wall to prevent the outer wall position from shifting due to loosening of the nuts during long-term use. The outer wall and the connecting beam are connected through nodes and limit bolts. There are two force transmission paths as a whole and nylon gaskets are used, which can further improve the structural redundancy and earthquake and wind resistance.
