Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to an assembled exterior wall large-scale complex-shaped construction structure and a construction method thereof. Background Art

[0002] In the field of construction engineering technology, prefabricated buildings are becoming more and more popular. Existing prefabricated exterior walls can be pre-processed and formed in the factory and then transported to the construction site for installation. Prefabricated exterior walls can greatly shorten the construction period and reduce the project cost. The anchoring performance of prefabricated exterior walls and steel structures is one of the main factors affecting the promotion and use of prefabricated exterior walls in steel structure buildings.

[0003] The existing prefabricated exterior walls have complex connection methods, slow construction speed, low anchoring strength, and no detachable function, which cannot reflect the advantages of fast construction speed of prefabricated buildings. Therefore, we propose a large-scale and complex-shaped prefabricated exterior wall construction structure and its construction method to solve the above problems. Summary of the invention

[0004] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a large-scale complex-shaped assembled exterior wall construction structure and a construction method thereof. The structure and method solve the problems of the existing assembled exterior walls having complex connection methods, slow construction speed, low anchoring strength, and no detachable function.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A large-scale and complex-shaped assembled exterior wall construction structure comprises a mounting beam fixedly mounted on the side of a floor slab, and an upper wall panel and a lower wall panel arranged on the upper and lower sides of the floor slab, wherein the upper wall panel and the lower wall panel are arranged on the upper and lower sides of the mounting beam respectively, and the upper wall panel, the lower wall panel and the mounting beam are connected via a connecting assembly, and the connecting assembly is arranged on the upper wall panel, the lower wall panel and the mounting beam via a fixing assembly, and the connecting assembly is arranged on a side away from the floor slab; the upper wall panel and the lower wall panel are both connected to the floor slab via a reinforcing plate, and the reinforcing plate is fixed to the upper wall panel and the lower wall panel via fixing bolts, and the reinforcing plate is fixed to the floor slab via connecting bolts.

[0006] The reinforcing plate is an L-shaped structural plate.

[0007] Positioning columns are arranged on both the upper and lower sides of the mounting beam frame, and positioning grooves matching the positioning columns are arranged in both the upper wall plate and the lower wall plate.

[0008] The upper wall plate and the lower wall plate are provided with mounting holes corresponding to the fixing bolts on one side surface close to the fixing bolts, the positioning column is provided with threaded holes matching the positions of the mounting holes, and one end of the fixing bolt extends into the threaded holes for connection and fixing.

[0009] The connecting assembly includes a fixing plate and a connecting plate. The fixing plates are provided in two groups. The two fixing plates are respectively arranged between the mounting beam and the upper wall plate, and between the mounting beam and the lower wall plate. The fixing plates are fixed to the mounting beam, the upper wall plate, and the lower wall plate through the fixing assembly, and the two fixing plates are connected through the connecting plate.

[0010] The fixing assembly includes a pushing block, a fixing block and a limiting rod. A fixing groove is provided on one side of the mounting beam, the upper wall plate and the lower wall plate close to the fixing plate. Limiting grooves are symmetrically provided on the upper and lower sides of the fixing groove. The fixing block is arranged in the fixing groove. A telescopic groove is provided in the fixing block. Two groups of limiting rods are symmetrically provided in the telescopic groove. One end of the two limiting rods away from each other is clamped in the limiting groove. A partition is provided on the limiting rod. A spring is sleeved on the outside of the limiting rod between the partition and the telescopic groove. A transmission bin is provided on the fixing plate. The pushing block is movably arranged in the transmission bin. The pushing block is arranged vertically to the limiting rod.

[0011] The contact surfaces of the pushing block and the limiting rod are both arranged as inclined surfaces.

[0012] The fixing assembly also includes a knob, a threaded rod and a threaded tube. The threaded tube is fixedly arranged in the transmission bin, the threaded rod is threadedly connected in the threaded tube, and two ends of the threaded rod are fixedly connected to the knob and the push block respectively.

[0013] The upper and lower surfaces of the floor plate are connected to the upper wall plate and the lower wall plate respectively through support rods.

[0014] A method for constructing a large-scale and complex-shaped assembled exterior wall comprises the following steps: The cam is then fixed to the bottom of the frame, and the cam is then fixed to the bottom of the frame, and the cam is then fixed to the top of the frame, and the cam is then fixed to the top of the frame, and the cam is then fixed to the bottom ...

[0015] Compared with the prior art, the present invention has the following beneficial effects: Through the pre-installed installation beams and the prefabricated matching between the positioning columns and the positioning grooves, not only can the lifting and positioning processes of the upper wall panels and the lower wall panels be made faster, but also by connecting the reinforcement plates to the upper wall panels, the lower wall panels and the floor panels to form a multi-point fixed structure, the anchoring strength of the entire wall can be significantly improved. The upper wall panels and the lower wall panels are connected as an integral whole through two fixing plates and a connecting plate, which not only improves the bearing capacity of the wall, but also reduces local stress concentration and prevents local failures caused by external forces, thereby improving the overall safety and stability of the wall panels.

[0016] The fixing components can be used to conveniently fix the fixing plates to the upper wall panel-installation beam frame and the lower wall panel-installation beam frame sides, forming a more solid connection, increasing the upper limit of the external load that the wall can withstand, and further strengthening the integrity of the structure, ensuring that the wall will not deform violently when encountering vibrations or other stresses. At the same time, the fixing components make the disassembly and assembly process quick, and workers can easily remove and replace the fixing plates when later maintenance or structural adjustments are required.

In addition, the upper wall panel 4 and the lower wall panel 3 form an integral connection through two fixing plates 501 and the connecting plate 502, which not only improves the bearing capacity of the wall, but also reduces local stress concentration and prevents local failure caused by external forces, thereby improving the overall safety and stability of the wall panel.

[0030] The support rod 14 provides additional lateral support force, which can effectively resist the lateral pressure on the wall caused by external loads, and can also effectively prevent bending and deformation of the wall. By providing constraints on the upper wall panel 4 and the lower wall panel 3, the lateral displacement can be limited, and the internal stress concentration caused by position changes when dynamic loads occur can be reduced, thereby protecting the integrity of the structure.
