Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a roof deformation joint structure with good sealing effect. Background Art

[0002] A Chinese patent with announcement number CN 203905314 U discloses a temperature deformation joint structure for the roof of a steel structure building. In order to solve the deformation and waterproofing problems of the upper and lower roof panels caused by thermal expansion and contraction, a reinforcing plate is used to support the end of the roof panel and connected to the metal water retaining, and then silicone sealant is used for detailed waterproof sealing. From the above content, it can be seen that although this method will not cause the roof panel to stretch and deform, since both ends are fixed by reinforcing plates, when the panel body expands and contracts, the panel surface will rise, which will break the original stress conditions at the connection between the panel body and other components, and will cause the connection and sealing to fail over time. In addition, due to the use of glue sealing, the construction cost and difficulty are increased. Summary of the invention

[0003] The object of the present invention is to provide a roof deformation joint structure with good sealing effect, which can meet the sealing requirements when the structure is deformed due to thermal expansion and contraction.

[0004] To achieve the above object, the present invention provides the following technical solutions: a roof deformation joint structure with good sealing effect, used for sealing between an upper roof panel and a lower roof panel, comprising a sealing member, a sliding connection member and a sliding connection groove, wherein the sliding connection groove is installed on an upper purlin, the sliding connection member is installed on the back side of the upper roof panel at a position corresponding to the upper purlin, and forms a sliding limit connection with the sliding connection groove along a length direction parallel to the upper roof panel;

[0005] The overlapping portion of the upper roof panel and the lower roof panel is connected in a dynamic seal through the sealing member.

[0006] Furthermore, the seal includes a first seal and a second seal; the first seal is arranged on the top of the ridge A on the front side of the lower roof panel and can be squeezed by the upper roof panel to fit the side of the ridge A and the surface of the plate body A; the second seal is arranged at the plate body A on the front side of the lower roof panel, and its two ends are respectively arranged behind the corresponding ends of the first seal on both sides; the lower end of the back side of the upper roof panel forms a dynamic seal with the first seal and the second seal.

[0007] Furthermore, the sliding connection member includes a first connection member and a second connection member, the first connection member and the sliding connection groove form a first sliding limit connection; the second connection member and the sliding connection groove form a second sliding limit connection.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, this embodiment discloses a roof deformation joint structure with good sealing effect, which is used for sealing between an upper roof panel 1 and a lower roof panel 11. As is well known, a roof structure includes a plurality of roof panels with the same structure. The upper roof panel 1 and the lower roof panel 11 in the present invention refer to the upper roof panel and the lower roof panel of two adjacent roof panels. The present invention includes a sealing member, a sliding connection member 3 and a sliding connection groove 7. The sliding connection groove 7 is installed on the upper purlin 4. The sliding connection member 3 is installed on the back side of the upper roof panel 1 at a position corresponding to the upper purlin 4, and forms a sliding limit connection with the sliding connection groove 7 along the length direction parallel to the upper roof panel 1.

[0026] In order to facilitate the installation of the connecting member, the present invention further includes a first reinforcing plate 2 and a second reinforcing plate 6 .

[0027] The first reinforcing plate 2 is installed on the back of the upper roof panel 1, and the sliding connector 3 is fixed on the first reinforcing plate 2. The second reinforcing plate 6 is installed on the back of the lower roof panel 11 and is fixedly connected to the top of the lower purlin 5. The reinforcing plate and the roof panel are connected by rivets 10.

[0028] like Figure 6 As shown, as a preferred example, the sliding connection member 3 includes a first connection member 3.1 and a second connection member 3.2, the first connection member 3.1 forms a first sliding limit connection with the sliding connection groove 7; the second connection member 3.2 forms a second sliding limit connection with the sliding connection groove 7. The first sliding limit connection and the second sliding limit connection enable the first connection member 3.1 and the second connection member 3.2 to slide linearly in the sliding connection groove 7 only without vertical displacement, thereby preventing the lower end of the roof panel from being lifted and affecting the sealing effect.

[0029] Regarding the selection of the connection components, the first connection member 3.1 and the second connection member 3.2 are both channel steels, preferably 5# channel steels, and the sliding connection groove 7 is C-shaped steel, preferably TH-E40*22*13*3 C-shaped steel.

[0030] The lower web 7 a of the sliding connection groove 7 is fixed to the top of the upper purlin 4 , and the upper wing plates of both the first connecting member 3 . 1 and the second connecting member 3 . 2 are fixed to the first reinforcing plate 2 .

[0031] The lower web 7a of the sliding connection groove 7 forms a first sliding limit connection with the lower wing plate 3.1a of the first connecting member 3.1, so that the lower web 7a limits the downward movement of the lower wing plate 3.1a perpendicular to the plate surface, and the upper web 7b of the sliding connection groove 7 forms a second sliding limit connection with the lower wing plate 3.2a of the second connecting member 3.2, so that the upper web 7b limits the upward movement of the lower wing plate 3.2a perpendicular to the plate surface.

[0032] The overlapping parts of the upper roof panel 1 and the lower roof panel 11 are connected in a dynamic seal via a seal.

[0033] like Figure 2-4 As shown, as a preferred example, the seal includes a first seal 8 and a second seal 9; the first seal 8 is arranged at the top of the ridge A11.1 on the front of the lower roof panel 11 and can be pressed by the upper roof panel 1 to fit on the side of the ridge A11.1 and the surface of the plate body A11.2; the second seal 9 is arranged at the plate body A11.2 on the front of the lower roof panel 11, and its two ends are respectively arranged behind the corresponding ends of the first seal 8 on both sides. The lower end of the back of the upper roof panel 1 forms a dynamic seal with the first seal 8 and the second seal 9. Therefore, it can be known that when the seal is fixed, the upper roof panel 1 is installed. After the upper roof panel 1 is installed in place, the lower end of its ridge B1.1 will squeeze the first seal 8 on the ridge A11.1, causing it to deform and fit with the surfaces of the two sides, and the lower end of the plate body B1.2 of the upper roof panel 1 will squeeze the end of the first seal 8 extending down and the second seal 9, so that the two seals form an overlapping fit, and the roof panel and the seal fit, thereby forming a seal. When the two roof panels are relatively displaced, the seal can still play a role of waterproof and windproof. Since the first seal 8 and the second seal 9 are independently provided and installed by adhesive backing, no glue sealing is required, so the installation method is simple and the cost is low.

[0034] As a preferred example, the first sealing member 8 and the second sealing member 9 are foamed silicone strips with adhesive on the back, and the foamed silicone strips have good deformation ability, thereby meeting the sealing effect under the conditions of this patent.
