Description

Technical Field

[0001] The invention relates to a building wall panel, in particular to an assembled building prefabricated wall panel. Background Art

[0002] Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories. Building components and accessories such as floor slabs and wall panels are processed and manufactured in factories, transported to the construction site, and installed on the building frame on site through reliable connection methods. The wall panels (including wall panels with window openings and wall panels without window openings) are concrete wall panels, and their height is the same as the height between two adjacent ring beams. The building frame at the construction site includes a ring beam on each layer. On one face (south face, north face, etc.) of each ring beam, the wall panels on that face are installed on the ring beam. The wall panels on that face can be one wall panel or two or more wall panels arranged in sequence on the left and right. The wall panels installed on the ring beam refer to that each wall panel is installed between two adjacent ring beams and attached to the outer side of the ring beam. The defects of the prefabricated concrete wall panels are poor thermal insulation performance; secondly, the weight is large, which is not only unfavorable for transportation and installation, but also causes a large load on the ring beam; finally, the production efficiency is low and dust is easily generated. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a white steel vacuum wall panel.

[0004] The objective of the present invention is achieved in this way: it is a flat rectangular white steel box, which has two front and rear panels and four thickness panels of upper, lower, left and right, wherein the thickness of the upper and lower thickness panels is greater than the thickness of the remaining four panels; ordinary steel lining plates are attached to the inner side of each of the remaining four panels, namely the front and rear panels and the left and right thickness panels, and the ordinary steel lining plates attached to the front and rear panels are respectively called front and rear lining plates, so that the remaining four panels are inner and outer double-layer metal plates to enhance the strength of the white steel vacuum wall panels; an exhaust nozzle for evacuating the white steel box cavity into a vacuum is arranged on the front panel or the rear panel; a number of rock wool support columns are arranged in the cavity of the white steel box and are supported between the front and rear lining plates to prevent the front and rear panels of the white steel box from deforming when the cavity is evacuated into a vacuum.

[0005] The height of the present invention is the same as the height of the two adjacent ring beams, and the height of the two adjacent ring beams refers to the distance between the upper surfaces of the two ring beams. Like the concrete wall panel, the present invention is also installed between the two adjacent ring beams and attached to the outer side of the ring beam. Specifically, the white steel box cavity is first evacuated into a vacuum through the vacuum nozzle; the upper thickness panel of the vacuum white steel box is aligned with the upper surface of the upper ring beam and is in the same plane, and the lower thickness panel of the white steel box is close to the upper surface of the lower ring beam. The white steel vacuum wall panel is hung on the ring beam using a connecting steel belt. The way to hang the ring beam is to embed nuts on the upper surfaces of the upper and lower ring beams; then set the upper and lower connecting steel belts, and the outer ends of the upper and lower connecting steel belts are welded to the upper and lower thickness panels of the white steel box respectively; each connecting steel belt has a screw hole at the inner end, and the upper and lower bolts that match the embedded nuts pass through the screw holes of the respective connecting steel belts, and are correspondingly screwed into the embedded nuts of the upper and lower ring beams, so that the white steel vacuum wall panel is installed between the two adjacent ring beams. The number of upper and lower connecting steel strips can be set as needed. If more than two of the present invention are used for each layer and each wallboard, the adjacent white steel vacuum wallboards are fixed by adhesive. The upper and lower adjacent white steel vacuum wallboards are fixed by adhesive.

[0006] Compared with the prior art, the present invention has the following positive effects: since it is a vacuum wall, the thermal insulation performance is significantly improved, and it also has a sound insulation effect; secondly, it is light in weight, which is not only conducive to transportation and installation, but also greatly reduces the load on the ring beam; thirdly, it has high production efficiency and does not generate dust during the production process; finally, it has beautiful appearance and is easy to beautify the appearance.

[0014] See also Figure 1-4The invention discloses a flat rectangular white steel box 10, which comprises a front panel 11, a rear panel 12, an upper thickness panel 13, a lower thickness panel 14, a left thickness panel 15 and a right thickness panel 16, wherein the upper thickness panel 13 and the lower thickness panel 14 have the same plate thickness of 2d, and the remaining four panels have the same plate thickness of d (d can be selected according to the needs of the building, and about 0.8mm can be selected for ordinary buildings); a common steel lining plate is attached to the inner side of each of the remaining four panels, including a front lining plate 21 of the common steel lining plate attached to the front panel 11, a rear lining plate 22 of the common steel lining plate attached to the rear panel 12, a left lining plate 23 attached to the left thickness panel 15 and a right lining plate 24 attached to the right thickness panel 16, so that the remaining four panels are inner and outer double-layer metal plates, wherein the thickness of the inner plate (lining plate) is greater than the thickness of the outer plate (white steel plate), for example, the thickness of the inner plate is twice the thickness of the outer plate, so as to reduce the cost of the invention while ensuring the strength. Under the premise of meeting the strength requirements, a weight-reducing hole 25 is set on each lining plate, and an exhaust nozzle 30 for evacuating the white steel box cavity into a vacuum is set at the upper right corner of the front panel; a number of rock wool support columns 40 are set between the front and rear lining plates in the cavity of the white steel box to prevent the front and rear panels of the white steel box from deforming when the cavity is evacuated into a vacuum. Each rock wool support column 40 is cylindrical and includes two circular end faces in the front and rear. In order to prevent the rock wool support column between the front and rear panels from being dislocated or tipped over, an axial steel bar 41 is embedded in the center of the column, and a welding head 411 is exposed on each end face. The welding head of the front end face is welded to the adjacent front lining plate 21, and the welding head of the rear end face is welded to the adjacent rear lining plate 22.

[0015] See also Figure 5 and 6The height of the present invention is the same as the height of two adjacent layers of ring beams, and the height of two adjacent layers of ring beams refers to the distance between the upper surfaces of the two layers of ring beams. Like concrete wall panels, the present invention is also installed between two adjacent layers of ring beams and attached to the outer side of the ring beams. Specifically, the white steel box cavity is first evacuated into a vacuum through an exhaust nozzle; the upper thickness panel 13 of the present invention is aligned with the upper surface of the upper ring beam 5 and is in the same plane, and the lower thickness panel 14 is close to the upper surface of the lower ring beam 7 (the upper and lower ring beams refer to two adjacent layers of ring beams), and the white steel vacuum wall panel is hung on the ring beam using a connecting steel belt 3. The method of hanging the ring beam is to embed nuts 4 on the upper surfaces of the upper and lower ring beams; then upper and lower connecting steel belts 3 are provided, and the outer ends of the upper and lower connecting steel belts are respectively welded (8 is the welding point) to the upper and lower thickness panels of the white steel box; each connecting steel belt has a screw hole at the inner end, and the upper and lower bolts 2 that cooperate with the embedded nuts pass through the screw holes of their respective connecting steel belts and are correspondingly screwed into the embedded nuts 4 of the upper and lower ring beams to install the white steel vacuum wall panel between the two adjacent layers of ring beams. The number of upper and lower connecting steel strips can be set as needed. If more than two of the present invention are used for each layer and each wallboard, the adjacent white steel vacuum wallboards (including the upper and lower adjacent white steel vacuum wallboards) are fixed by gluing. When the upper and lower adjacent white steel vacuum wallboards are hung on the ring beam, the same bolt and nut can be used. A low-radiation heat insulation film is pasted on the front panel 11 or the rear panel 12 in the white steel box cavity.
