Description

[0001] The invention relates to the technical field of assembled structures, in particular to a large-span prefabricated assembled structure with an elastic clamping fixing mechanism. Background Art

[0002] Prefabricated buildings are one of the key points of the construction industry reform in recent years, and one of the green buildings strongly advocated by the country. In the current housing construction and civil engineering fields, the application of prefabricated building structures is becoming more and more extensive.

[0003] When assembling existing large-span prefabricated assembled structures, welding is usually used to fix the support rods and the crossbeam frames. This method not only requires a lot of on-site work, but also the assembly accuracy is difficult to ensure, which can easily lead to structural instability. Especially in large-scale projects, this assembly method is more time-consuming and labor-intensive, and inefficient. At the same time, since the connection between the support rod and the bottom frame often only relies on simple clip-on or bolt connection, the fixing effect is poor and it is easy to loosen or deform when subjected to external force, thereby affecting the stability and safety of the entire structure. Summary of the invention

[0004] The object of the present invention is to provide a large-span prefabricated assembly structure with an elastic snap-fit ​​fixing mechanism to solve the technical problems raised in the above-mentioned background technology or to achieve better technical effects.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-span prefabricated assembly structure with an elastic clamping and fixing mechanism, comprising a large-span crossbeam frame, six support rods are arranged at the bottom of the large-span crossbeam frame, and six bottom end frames are fixedly connected to the bottom of the large-span crossbeam frame, a groove is provided in the support rod near the top, the top of the support rod penetrates into the interior of the bottom end frame and is clamped with the bottom end frame, fixing grooves are provided at the top positions on both sides of the bottom end frame, and limiting grooves are provided at the bottom positions on both sides of the bottom end frame, and the bottom positions on both sides of the corresponding grooves in the support rod are slidably connected to limiting plates, and the opposite sides of the two limiting plates respectively penetrate into the two limiting grooves. The cam is secured to the upper and lower edges of the two support rails and are secured to the bottom edges of the two support rails.

[0006] Preferably, three longitudinal beams are fixedly installed inside the large-span cross beam frame by bolts.

[0007] Preferably, the tops of both sides of the support rod are fixedly connected to limit frames, the shape of the limit frames is designed to be L-shaped, and the inner side of the limit frames is tightly attached to the outer side of the bottom frame.

[0008] Preferably, positioning blocks are fixedly connected to both sides of the top of the support rod, and the top of the positioning block penetrates into the interior of the bottom frame and is clamped with the bottom frame.

[0009] Preferably, the bottom end of the inner side of the bottom frame is designed to be in an arc shape.

[0010] Preferably, a reinforcing rod is fixedly connected to the center of the bottom of the groove, a fixing rod is fixedly connected to the top of the reinforcing rod, a movable groove is opened inside the limiting plate, both sides of the fixing rod respectively penetrate into the interior of the two movable grooves and are fixedly connected with circular blocks, the circular blocks are slidably connected to the movable grooves, and a limiting spring is provided on the outer side of the fixing rod corresponding to the inner sleeve of the movable groove, and both sides of the limiting spring are respectively fixedly connected to one side in the movable groove and the circular block.

[0011] Preferably, the shapes of the opposite ends of the two fixed elastic members are both designed to be arc-shaped, and the shape of the bottom end of the push plate is designed to be arc-shaped.

[0012] Preferably, the shapes of the two opposing sides of the two limiting plates are both arc-shaped.

[0013] The present invention also discloses a large-span prefabricated assembly method with an elastic clamping fixing mechanism, comprising the following steps:

[0014] Step 1: Place the long-span beam frame at the predetermined position, ensure that the bottom surface is flat, place the six support rods at the bottom of the long-span beam frame respectively, and achieve preliminary positioning by connecting the positioning blocks on the top of the support rods with the inside of the bottom frame. Use the limit frame to fit closely to the outside of the bottom frame to ensure that the relative position between the support rods and the bottom frame is stable.

[0015] Step 2. When the top of the support rod passes through the bottom frame, preliminary fixation is achieved through the interaction between the groove in the support rod and the bottom frame. In the groove, the limit plate is connected to the circular block on the fixed rod through the movable groove under the action of the limit spring, so that the limit plate can slide outward. When the support rod is fully inserted into the bottom frame, the limit plate is pushed by the limit spring to pass through the limit groove and engage with the inner wall of the limit groove, thereby completing the fixation of the support rod and the bottom frame.

[0016] Step three, the fixed elastic part in the support rod is in the groove, and its shape is designed to be arc-shaped, which matches the arc-shaped bottom of the push plate. When the push plate is pushed downward by the connecting plate, the two sides of the push plate contact with the fixed elastic part and push the fixed elastic part to move outward until the fixed elastic part penetrates into the fixed groove and engages with the fixed groove, thereby completing the fixation of the connecting plate and the large-span beam frame.

[0017] Step 4: Install three longitudinal beams inside the long-span beam frame by bolts to enhance the bearing capacity and stability of the beam frame. The reinforcing rod at the bottom of the groove is connected to the fixing rod to provide additional support to ensure the stable operation of the limit plate and the fixed elastic parts. Finally, fix the connecting plate to the long-span beam frame by fixing bolts.

[0018] Compared with the prior art, the beneficial effects of the present invention include:

[0019] The large-span prefabricated assembly structure with an elastic clamping fixing mechanism realizes accurate positioning and fixing between the support rods and the bottom frame by arranging six support rods at the bottom of the large-span crossbeam frame and utilizing the interaction between the grooves in the support rods and the bottom frame. This design avoids the problem of difficult to ensure assembly accuracy caused by traditional welding methods and significantly improves the stability of the structure. In particular, the limiting plates and fixing elastic parts arranged inside the support rods can ensure that the fixing between the support rods and the bottom frame is more firm through their cooperation, effectively preventing loosening or deformation caused by external forces, and realizing The rapid positioning and preliminary fixation between the support rod and the bottom frame is realized, which greatly reduces the time and labor intensity of on-site operations. At the same time, through the coordinated use of push plates and fixed elastic parts, the connecting plate can be conveniently fixed on the large-span beam frame, further improving the assembly efficiency. Inside the large-span beam frame, three longitudinal beams are fixed and installed by bolts, which not only enhances the bearing capacity of the beam frame, but also improves the overall stability of the structure. The design of the reinforcing rod and the fixing rod at the bottom of the groove provides additional support for the limit plate and the fixed elastic parts, ensuring their stable operation when subjected to force, thereby enhancing the stability and safety of the entire structure.
