Description

Technical Field

[0001] The utility model relates to the technical field of color steel sandwich panels, in particular to a connection and sealing structure for color steel sandwich panels. Background Art

[0002] Color steel sandwich panel is a composite board with a color-coated steel plate as the panel and foam, rock wool, polyurethane and other materials as the core material in the middle, which is widely used in the fields of architecture, decoration, heat preservation, etc.; when installing color steel sandwich panels, a certain degree of sealing is required for the connection between color steel sandwich panels to prevent water vapor from entering the color steel sandwich panels, causing rust inside the color steel sandwich panels and damage to the inner core of the color steel sandwich panels, affecting the heat preservation effect of the color steel sandwich panels. The connection and sealing of color steel sandwich panels are crucial for ensuring the structural stability of color steel sandwich panels and improving their waterproof and heat preservation performance.

[0003] For example, the patent with the publication number CN214995174U discloses a sealed and assembled manual color steel plate, including a functional plate, a limiting hole, and a limiting rod; the functional plate is a plate-shaped structure, the limiting hole is arranged on the plate convex block and is an inwardly recessed structure, and the limiting rod is fixedly arranged on the plate groove and corresponds to the limiting hole; through the setting of the limiting structure and the automatic glue application structure, workers can accurately position the splicing plate and directly apply sealant during the installation process; this can not only reduce the errors caused by manual operation during the installation project of the device, but also ensure the accurate installation of the device and improve the sealing effect between the splicing plates.

[0004] However, the color steel sandwich panels in the above technology still have the following problems:

[0005] Since the upper and lower metal panels of the color steel sandwich panel are relatively thin and are easily deformed by force, when the limiting rod is inserted into the limiting hole and the sealant is extruded outward, the upper and lower metal panels are easily extruded and turned outward, resulting in a large gap at the connection and a poor sealing effect. If adjacent color steel sandwich panels are connected and fixed with screws, when the screws are tightened, the screws may squeeze the metal panel inward and cause deformation, resulting in pits and cracks in the metal panel of the color steel sandwich panel. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a connection and sealing structure for color steel sandwich panels, such as reducing the installation gap between color steel sandwich panels, and at the same time avoiding deformation of the color steel sandwich panels during installation with bolts, and improving the sealing performance of the installation connection of color steel sandwich panels.

[0007] To achieve the above object, the present utility model provides the following technical solution: A connection and sealing structure for color steel sandwich panels, comprising a panel. The panel consists of a face plate, a filling core material, and a bottom plate. Both sides of the panel are connected with splicing ends. One side of the splicing end far away from the panel is connected with a connection mechanism. The connection mechanism includes two symmetrically arranged sealing plates, and the two sealing plates are respectively connected with the face plate and the bottom plate of the panel. The splicing end is located between the two sealing plates. A number of symmetrically arranged bolt holes are respectively formed in the adjacent sides of the two sealing plates. Bolts are connected in a number of bolt holes on the sealing plate close to the face plate side. The other ends of the threaded rods of a number of bolts all penetrate through the splicing end and are respectively threadedly connected with a number of bolt holes on the other sealing plate.

[0008] Further, the splicing end includes a connection core material and two extension plates. The connection core material is fixedly connected with the filling core material, and the two extension plates are respectively fixedly connected with the face plate and the bottom plate. The two sealing plates are respectively connected with the mutually remote sides of the two extension plates. The threaded rods of a number of bolts all penetrate through the two sealing plates, the two extension plates, and the connection core material.

[0009] Further, both of the two extension plates are of an L-shaped structure, and the outer walls of the longer sides of the two L-shaped extension plates are mutually close and connected with the connection core material. The shorter ends of the two L-shaped extension plates are respectively fixedly connected with the adjacent sides of the face plate and the bottom plate.

[0010] Further, the two sealing plates respectively abut against the mutually remote sides of the two extension plates.

[0011] Further, a support plate is fixedly connected between the two sealing plates. One side of the support plate simultaneously abuts against the adjacent connection core material and the two extension plates.

[0012] Further, both sides of the support plate are fixedly connected with the middle positions of the two sealing plates.

[0013] Further, sealing gaskets are fixedly connected to the adjacent sides of the two sealing plates, and the other sides of the sealing gaskets abut against the adjacent extension plates.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] For this connection and sealing structure of color steel sandwich panels, through the upper and lower two sealing plates, the splicing ends between the panels can be wrapped, thereby reducing the entry of impurities, dust, etc. into the joints of the panels. At the same time, when using bolts to connect and fix the joints of the two panels, the upper and lower two sealing plates can prevent the bolts from squeezing the face plates and bottom plates on both sides of the panel, forming pits, and avoiding deformation of the panel.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figure 1 - Figure 4 , a color steel sandwich panel connection and sealing structure, including a plate 1, the plate 1 is composed of a panel 2, a filling core material 3 and a bottom plate 4, both sides of the plate 1 are connected with splicing ends, and a connection mechanism is connected to the side of the splicing end far from the plate 1. The connection mechanism includes two symmetrically arranged sealing plates 5, the two sealing plates 5 are respectively connected to the panel 2 and the bottom plate 4 of the plate 1, the splicing end is located between the two sealing plates 5, and a number of symmetrically arranged threaded holes 501 are respectively opened through the adjacent sides of the two sealing plates 5. Bolts 6 are connected in a number of threaded holes 501 on the sealing plate 5 close to the panel 2 side, and the other ends of the threaded rods of the number of bolts 6 penetrate through the splicing end and are respectively threadedly connected to a number of threaded holes 501 on the other sealing plate 5.

[0023] As Figure 1 - Figure 4 shown, a color steel sandwich panel connection and sealing structure in the present utility model is similar to the existing color steel sandwich panel connection and sealing structure. For example, a sealed and assembled manual color steel plate disclosed in the patent with the publication number CN214995174U. The main improvement point of the present utility model is that it can reduce the extrusion pits caused by screwing the plate 1 when using the bolt 6 for fixing, and further improve the connection sealing performance of the color steel sandwich panel. As Figures 1 to 4As shown in the figure, when the color steel sandwich panel connection and sealing structure in the present utility model is in use, two sealing plates 5 are respectively placed on the upper and lower sides of the splicing end on one side of the plate 1. Subsequently, bolts 6 are passed through the threaded holes 501 of the upper sealing plate 5 and screwed inward, penetrating the splicing end and connecting with the corresponding threaded holes 501 on the bottom sealing plate 5, thereby installing and fixing the sealing plate 5 to the plate 1. Then, the splicing end on one side of another plate 1 is inserted between the two fixed sealing plates 5, and the bolts 6 are used again to fix the splicing end to the sealing plate 5 through the threaded holes 501, thus completing the splicing and fixing between the two plates 1. The sealing plate 5 can be made of stainless steel plate or steel plate, so that when the bolt 6 is screwed, the sealing plate 5 will not be squeezed and deformed, resulting in pits, making the installed plate 1 smoother and not easily leaking water from the position where the bolt 6 is screwed. At the same time, the bolt 6 can use self-tapping screws, which is convenient for penetrating the splicing part.

[0024] As Figure 1 - Figure 4 shown, the splicing end includes a connecting core material 7 and two extension plates 8. The connecting core material 7 is fixedly connected to the filling core material 3, and the two extension plates 8 are respectively fixedly connected to the panel 2 and the bottom plate 4. The two sealing plates 5 are respectively connected to the sides of the two extension plates 8 that are away from each other. The threaded rods of several bolts 6 penetrate through the two sealing plates 5, the two extension plates 8, and the connecting core material 7. The connecting core material 7 of the splicing end and the filling core material 3 are made of the same type of integrally formed material, and the upper and lower two extension plates 8 are the extension ends of the panel 2 and the bottom plate 4, which can be integrally formed during the production of the plate 1.

[0025] As Figure 1 - Figure 4 shown, both of the two extension plates 8 are L-shaped structures, and the outer walls of the longer sides of the two L-shaped extension plates 8 are close to each other and connected to the connecting core material 7. The shorter ends of the two L-shaped extension plates 8 are respectively fixedly connected to the adjacent sides of the panel 2 and the bottom plate 4. By designing the extension plate 8 as an L-shaped and inwardly concave design, the sealing plate 5 is fitted and installed on the inner side of the L-shaped extension plate 8, so that the surfaces of the upper and lower two sealing plates 5 after installation can be flush with the surfaces of the panel 2 and the bottom plate 4, thereby making the sealing plates 5 after installation flush with the upper and lower two surfaces of the plate 1, improving the splicing and installation effect of the plate 1.

[0026] As Figure 1 - Figure 4 shown, the two sealing plates 5 respectively abut against the sides of the two extension plates 8 that are away from each other. During installation, the two sealing plates 5 are respectively attached to the sides of the upper and lower two extension plates 8, reducing the gap between the sealing plate 5 and the extension plate 8 after installation.

[0027] As Figure 1 - Figure 4As shown, a support plate 9 is fixedly connected between two sealing plates 5, and one side of the support plate 9 abuts against the adjacent connecting core material 7 and two extension plates 8 at the same time. Since the connecting core material 7 in the middle of the splicing end is usually a foam-like material, when the bolt 6 is used to screw the sealing plate 5, through the support of the support plate 9, the possibility of deformation of the sealing plate 5 caused by screwing can be reduced, and the structural strength of the sealing plate 5 can be improved.

[0028] As Figure 1 - Figure 4 shown, both sides of the support plate 9 are fixedly connected to the middle positions of the two sealing plates 5 respectively. The support plate 9 is arranged in the middle position between the two sealing plates 5 for support, so as to form an I-shaped structure, making the forces on both sides of the sealing plate 5 more uniform.

[0029] As Figure 1 - Figure 4 shown, sealing gaskets 10 are fixedly connected to the adjacent sides of the two sealing plates 5, and the other sides of the sealing gaskets 10 abut against the adjacent extension plates 8. By padding the sealing gaskets 10 between the sealing plates 5 and the extension plates 8, the sealing effect at the splicing position of the two plates 1 is further improved.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
