Description

Technical Field

[0001] The utility model relates to the technical field of assembled exterior wall thermal insulation wall structures, and particularly relates to an assembled mesh structure exterior wall panel. Background Art

[0002] An assembled exterior wall panel is a modern building component widely used in prefabricated building systems. Its characteristic is that the structure and finish of the exterior wall are prefabricated in the factory and then transported to the site for assembly. This method greatly improves the construction efficiency of buildings, reduces the on-site operation time and cost, and at the same time also improves the environmental protection performance and quality control level of buildings. The following are some key characteristics and applications of assembled exterior wall panels:

[0003] 1. Modular design: Assembled exterior wall panels adopt modular design, and the dimensions and styles are customized according to the specific needs of the building, including different thermal insulation performances, finish materials and colors, to meet the diverse building styles and functional requirements.

[0004] 2. High-performance materials: Exterior wall panels usually adopt high-performance building materials such as concrete, metal, composite materials, etc. These materials have good weather resistance, fire resistance and thermal insulation performance, and can significantly improve the energy efficiency and living comfort of buildings.

[0005] 3. Quick installation: Since the exterior wall panels are prefabricated in the factory, only hoisting and splicing are required on site, which greatly reduces the on-site construction time and labor requirements and improves the construction efficiency.

[0006] 4. High precision and quality control: Produced in a controlled factory environment, more strict dimensional and quality control can be achieved, ensuring the precision and consistency of each exterior wall panel, thereby improving the construction quality and appearance effect of the overall building.

[0007] 5. Environmental protection and sustainability: Assembled exterior wall panels reduce on-site wet operations, reduce noise and dust pollution during construction. At the same time, due to the efficient use and recyclability of materials, it helps to achieve the green and sustainable development goals of the construction industry.

[0008] 6. Convenient maintenance: The modular structure of the exterior wall panels is convenient for later maintenance and replacement. If there is damage or aging, only the damaged part needs to be replaced separately without affecting the entire wall. Assembled exterior wall panels have a wide range of applications, from residential buildings to commercial complexes, from schools, hospitals to industrial factories. With the continuous development of building technology, the design and materials of assembled exterior wall panels are also constantly innovating to meet more complex and diversified building needs.

[0009] At present, during the installation process, the connectors of prefabricated exterior wall panels need to be assembled first and then drilled and installed. This requires installation piece by piece and the use of a long drill bit. The construction is time-consuming and labor-intensive, and the installation efficiency of the connectors is low.

[0010] Therefore, there is an urgent need to design an assembled mesh structure exterior wall panel to solve the problem of time-consuming, labor-intensive and low-efficiency construction caused by existing integral tensioning parts. Utility Model Content

[0027] The following will further describe the technical solutions in the embodiments of the present utility model clearly and completely with reference to the drawings in the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 - 4 shown, a prefabricated mesh structure exterior wall panel includes a barrier layer 1, an insulation layer 2, a connecting piece 4, an inner mesh 5, an outer mesh 6 and a diagonal wire 7. The barrier layer 1 and the insulation layer 2 are installed on the wall 3 through the connecting piece 4. The barrier layer 1 adopts a gypsum board which is moisture-proof and fire-proof, and the insulation layer 2 adopts an integrated board for heat insulation.

[0029] The barrier layer 1 is located inside the thermal insulation layer 2. An inner mesh sheet 5 is arranged inside the barrier layer 1, and an outer mesh sheet 6 is arranged outside the thermal insulation layer 2. An inclined wire 7 is connected between the inner mesh sheet 5 and the outer mesh sheet 6. The inclined wire 7 is made of steel wire and crosses through the barrier layer 1 and the thermal insulation layer 2 to connect the inner mesh sheet 5 and the outer mesh sheet 6. The inner mesh sheet 5 and the outer mesh sheet 6 wrap the barrier layer 1 and the thermal insulation layer 2 into an integral structure.

[0030] The connecting piece 4 adopts a split structure of a pull rod 4.1 and a fixed end sleeve 4.2. A fixing hole 4.3 is drilled on the wall body 3, and the fixed end sleeve 4.2 is pre-arranged in the fixing hole 4.3. The fixed end sleeve 4.2 is hammered into the fixing hole 4.3. A number of barbs 4.4 are arranged outside the fixed end sleeve 4.2. The barbs 4.4 are inclined outward towards the opening of the fixed end sleeve 4.2. The barbs 4.4 are in close contact with the inner wall of the fixing hole 4.3, and the outer ends of the barbs 4.4 are abutted against the inner wall of the fixing hole 4.3 to prevent being pulled out by the pull rod 4.1.

[0031] Two end sleeve stoppers 4.5 are oppositely arranged inside the fixed end sleeve 4.2. The length of the end sleeve stopper 4.5 is half of that of the fixed end sleeve 4.2, and the end sleeve stopper 4.5 is arranged on the side close to the opening of the fixed end sleeve 4.2.

[0032] Two limiting grooves 4.6 are formed between the two end sleeve stoppers 4.5. The outer sides of the limiting grooves 4.6 are of a flared structure that expands outward. The diameter of the inner circle formed between the pull rod 4.1 and the two end sleeve stoppers 4.5 is the same. When the pull rod 4.1 is inserted into this inner circle, it squeezes the two end sleeve stoppers 4.5 to expand, making the barbs 4.4 more closely contact the inner wall of the fixing hole 4.3. Two pull rod stoppers 4.7 are oppositely arranged on the pull rod 4.1. The pull rod stoppers 4.7 enter the limiting grooves 4.6 through the flared structure. The pull rod stoppers 4.7 enter the inner side of the end sleeve stoppers 4.5 through the limiting grooves 4.6, and the pull rod 4.1 is rotated to control the pull rod stoppers 4.7 to block on the inner side of the end sleeve stoppers 4.5.

[0033] The other side of the pull rod 4.1 is provided with an external thread. A backing plate 4.8 is sleeved on the pull rod 4.1. A nut 4.10 is screwed on the external thread of the pull rod 4.1. A sealing cover 4.9 is arranged outside the nut 4.10. A threaded hole is arranged in the middle of the sealing cover 4.9. The sealing cover 4.9 is screwed on the external thread of the pull rod 4.1. The pull rod 4.1 passes through the inner mesh sheet 5, the barrier layer 1, the thermal insulation layer 2 and the outer mesh sheet 6, and the edge of the sealing cover 4.9 abuts against the outer mesh sheet 6.

[0034] The connecting piece 4 of the present utility model adopts a split structure. When installing on the wall, first hammer the fixed-end sleeve 4.2 into the fixing hole 4.3 with a hammer, and then install the pull rod 4.1 so that the pull rod stopper 4.7 abuts against the inner side of the end sleeve stopper 4.5. Through holes are preset on the integral exterior wall panel, or the outer end of the pull rod 4.1 penetrates through the integral exterior wall panel. Finally, install the nut 4.10 and the sealing cover 4.9 for fixation, reducing the labor intensity and improving the work efficiency.
