Abstract
Description
Technical Field
[0001] This application relates to the field of prefabricated building technology, and more specifically, to a quick connection device for prefabricated buildings. Background Technology
[0002] In the field of prefabricated buildings, connection technology is a key element in ensuring the stability, safety, and construction efficiency of building structures. Traditional building connection methods typically employ welding, bolting, or cast-in-place concrete. These methods have many limitations in practical applications. Welding requires specialized welding techniques and equipment, resulting in slow construction speeds. Bolting connections require precise alignment of holes, making construction more difficult.
[0003] To address the aforementioned problems, this application provides a quick connection device for prefabricated buildings. Utility Model Content
[0004] The quick connection device for prefabricated buildings provided in this application adopts the following technical solution:
[0005] A quick connection device for prefabricated buildings includes a first connection mechanism, a second connection mechanism on one side of the first connection mechanism, a symmetrical locking mechanism on one 180° side formed by the first and second connection mechanisms, and an upper and lower symmetrical adapter groove on one 180° side formed by the first and second connection mechanisms, wherein an anti-offset mechanism is provided in the adapter groove.
[0006] Furthermore, both the first and second connecting mechanisms are right-angled structures, and the locking mechanism is engaged with one side of the 180° surface formed by the first and second connecting mechanisms through an anti-offset mechanism.
[0007] Furthermore, the first connecting mechanism includes a first right-angle connecting part, an embedded groove is provided through the right-angle side of the first right-angle connecting part near the second connecting mechanism, a uniformly distributed first fixing hole is provided through the first right-angle connecting part, and a relatively symmetrical first connecting ear is provided between the right-angle side of the first right-angle connecting part away from the second connecting mechanism and the first fixing hole.
[0008] Furthermore, the second connecting mechanism includes a second right-angle connecting part, and an embedded block is provided on the side of the second right-angle connecting part near the first connecting mechanism. The embedded block is embedded in the embedded groove. The second right-angle connecting part and the embedded block are both provided with evenly distributed second fixing holes. The side of the second right-angle connecting part away from the first connecting mechanism is provided with mutually symmetrical second connecting ears, and the second connecting ears are all located between the opposite second fixing holes.
[0009] Furthermore, the anti-offset mechanism includes a mounting plate, and the mounting plate has snap-fit plates at both the upper and lower ends on the side near the first right-angle connecting part and the second right-angle connecting part. The anti-offset mechanism is fixed to the first connecting mechanism and the second connecting mechanism by snap-fit plates and adapter slots. The middle section of the mounting plate near the first connecting mechanism and the second connecting mechanism has a snap-fit block, and the snap-fit plates and snap-fit blocks form two clearance slots.
[0010] Furthermore, the locking mechanism includes two fixing bolts, each with a fixing plate extending through both ends. Each fixing plate has a fixing nut at its bottom, and the fixing bolts are located within the clearance groove formed by the snap-fit plate and the snap-fit block.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] By utilizing the interlocking groove and the interlocking block, along with the design of the locking mechanism's fixing bolts and the fixing plate, rapid positioning and connection of components are achieved, significantly shortening construction time. The first and second connection mechanisms adopt standardized designs, facilitating mass production and on-site assembly, further improving construction efficiency. The interlocking design of the interlocking groove and the interlocking block ensures precise alignment during connection, avoiding deviation problems that may occur in traditional connection methods. The anti-offset mechanism effectively prevents possible offset during connection through the snap-fit plate and the adapter groove, ensuring the stability and reliability of the connection. Through the interlocking of the interlocking structure and the fixing holes, construction personnel can complete the connection without complex tools and techniques, reducing construction difficulty.
