Description

Technical Field

[0001] This utility model belongs to the field of wall panel technology, and specifically relates to an ultra-high performance precast concrete wall panel. Background Technology

[0002] Precast concrete refers to concrete products that are prefabricated in a factory or on-site at locations other than the final design, and then transported to the construction site for assembly and connection. Precast concrete wall panels are reinforced concrete wall panels for building construction, prefabricated in a prefabrication yard. They have the following characteristics: Production method: Precast concrete wall panels are produced in a factory according to predetermined dimensions and specifications, ensuring high precision and good structural performance; Material composition: Precast wall panels are mainly composed of steel reinforcement and concrete, with the steel reinforcement providing tension and the concrete providing compressive strength, making the wall panels both strong and durable; Fast installation speed: Because the wall panels are prefabricated, on-site installation is very fast, significantly improving construction efficiency; Reliable quality: Factory production ensures controllable quality of the wall panels, reducing errors from on-site wet work and manual operation.

[0003] Cost-effectiveness: The production of precast wall panels has the advantage of economies of scale, which can reduce production costs and reduce the manpower and material resources required for on-site construction; environmental protection and energy saving: the production process of precast wall panels is energy-saving and environmentally friendly, reducing noise, waste and carbon dioxide emissions generated during on-site construction.

[0004] Existing precast concrete wall panels are difficult to position accurately during splicing. Furthermore, the large size and weight of precast concrete wall panels make positioning and adjustment difficult. Additionally, there are large joints after splicing two wall panels, and traditional grouting methods for filling these joints are cumbersome and difficult to implement. Therefore, there is a need for an ultra-high performance precast concrete wall panel to solve the problems existing in the current technology. Utility Model Content

[0008] It is worth noting that the positioning tube is equipped with an air valve, and the filling air column is equipped with an inflation chamber.

[0009] Furthermore, it should be noted that a filling groove is provided on one side of the opposite surface of the first precast wall panel and the second precast wall panel, and a positioning receiving groove is provided on the upper and lower surfaces of the first precast wall panel and the second precast wall panel.

[0010] In a preferred embodiment, positioning holes are provided at the positions where the first precast wall panel is opposite to the upper connecting rod and the lower connecting rod, and at the positions where the second precast wall panel is opposite to the upper connecting rod and the lower connecting rod, and the upper connecting rod and the lower connecting rod are adapted to the positioning holes.

[0011] In a preferred embodiment, the lower end of the upper connecting rod is fixed with a connecting pin, and the upper end face of the lower connecting rod is provided with a connecting groove, wherein the connecting pin is adapted to the connecting groove.

[0012] Compared with the prior art, the ultra-high performance precast concrete wall panel provided by this utility model has at least the following beneficial effects:

[0013] Through the set splicing mechanism, the upper positioning cover plate and the lower positioning cover plate can lock the docking assembly of the first precast wall panel and the second precast wall panel. At the same time, the upper docking rod and the lower docking rod can play a positioning and guiding role during the docking process, thereby ensuring the docking and installation quality of the first precast wall panel and the second precast wall panel.

[0014] With the set splicing and filling components, after the first precast wall panel and the second precast wall panel are connected, air is injected into the filling air column from the valve. In this way, the inflated filling air column can seal and fill the joint between the first precast wall panel and the second precast wall panel. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Please see Figure 1-4 This utility model provides an ultra-high performance precast concrete wall panel, including a first precast wall panel 1 and a second precast wall panel 2, which are arranged opposite to each other. A splicing mechanism is provided between the first precast wall panel 1 and the second precast wall panel 2. The splicing mechanism is installed between the first precast wall panel 1 and the second precast wall panel 2 for connecting the first precast wall panel 1 and the second precast wall panel 2. The splicing mechanism includes an upper positioning cover plate 3, a lower positioning cover plate 4, a docking component, and a splicing caulking component.

During use, the filling air column 9 is contained in the filling groove 12 of the first precast wall panel 1 and the second precast wall panel 2. After the first precast wall panel 1 and the second precast wall panel 2 are joined together, air is injected into the filling air column 9 from the air valve 11. In this way, the inflated filling air column 9 can seal and fill the joint between the first precast wall panel 1 and the second precast wall panel 2. The air filling method replaces the traditional grouting filling method. The whole process is simple and convenient, and improves the assembly efficiency of the precast wall panels.

At the same time, the upper connecting rod 5 and the lower connecting rod 6 can play a positioning and guiding role during the docking process, thereby ensuring the docking and installation quality of the first precast wall panel 1 and the second precast wall panel 2.

[0029] Furthermore, the lower end of the upper connecting rod 5 is fixed with a connecting pin 7, and the upper end face of the lower connecting rod 6 is provided with a connecting groove 8; the connecting pin 7 is adapted to the connecting groove 8, so that the connecting pin 7 is positioned in the connecting groove 8.

[0030] Furthermore, positioning holes 14 are provided at the positions of the first precast wall panel 1 relative to the upper connecting rod 5 and the lower connecting rod 6, and at the positions of the second precast wall panel 2 relative to the upper connecting rod 5 and the lower connecting rod 6; the upper connecting rod 5 and the lower connecting rod 6 are adapted to the positioning holes 14.
