Background Art

[0002] Steel structure factories or houses are the main structures of large factories at this stage. Although the insulation requirements of steel structure factories are not as high as those of residential buildings, their waterproof and thermal insulation designs also need to meet the requirements of workshops. Therefore, the waterproof and thermal insulation of steel structure factory roofs have always been a hot topic of research for technical personnel in this field.

[0003] At present, roof insulation mainly relies on insulation layers, such as extruded boards, foam boards, rock wool, etc., and the insulation layer is usually fixed on the surface of the steel plate to achieve the insulation effect. However, due to the large construction area of ​​the steel structure factory, the size of its roof is also large, so the construction of the roof requires the splicing of steel plates. The existing technology focuses more on the design of the insulation steel plate structure, and rarely pays attention to the insulation and waterproofing of the splicing of the insulation steel plates, which will directly affect the overall insulation of the factory.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop an insulation structure suitable for steel structure roofs. Utility Model Content

[0058] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] See also Figures 1 to 5 As shown;

[0060] This embodiment discloses a thermal insulation structure suitable for a steel structure roof, the thermal insulation structure comprising:

[0061] Multiple spliced ​​external insulation steel plate structure 1; and

[0062] An inner insulation layer 11 is arranged on the spliced ​​outer insulation steel plate structure 1 close to the indoor side of the steel structure workshop;

[0063] The spliced ​​external insulation steel plate structure 1 includes:

[0064] An inner steel plate 101 and an outer steel plate 102; and

[0065] An intermediate insulation layer 103 disposed between the inner steel plate 101 and the outer steel plate 102;

[0066] An installation portion 104 is formed at the edge of the spliced ​​external insulation steel plate structure 1 , and the installation portions 104 of adjacent spliced ​​external insulation steel plate structures 1 are close to each other, and the installation portions 104 of adjacent spliced ​​external insulation steel plate structures 1 are connected by an I-shaped insulation connector 2 .

[0067] Specifically, the present embodiment discloses a novel spliced ​​external insulation steel plate structure 1, and a steel structure roof 10 is formed by splicing a plurality of spliced ​​external insulation steel plate structures 1. The spliced ​​external insulation steel plate structure 1 of the present embodiment clamps the intermediate insulation layer 1032 by the inner steel plate 101 and the outer steel plate 102, and after construction, an inner insulation layer 11 is arranged on the indoor side of the spliced ​​external insulation steel plate structure 1. The insulation layer of the present embodiment can be made of any commonly used insulation material such as extruded board, foam board, rock wool, etc., and the steel plates on both sides are connected by gluing and fixing. At the same time, considering the roof splicing structure of a large factory building, the adjacent spliced ​​insulation steel plates of the present embodiment need to be connected by the above-mentioned I-shaped insulation connector 2. Therefore, in order to facilitate installation and splicing, the spliced ​​external insulation steel plate structure 1 of the present embodiment is provided with a mounting portion 104, and the installation is achieved by the mounting portion 104 cooperating with the I-shaped insulation connector 2.

[0068] Preferably, the size of the inner steel plate 101 of this embodiment is smaller than the size of the outer steel plate 102;

[0069] When the inner steel plate 101 and the outer steel plate 102 are matched, the center of the inner steel plate 101 coincides with the center of the outer steel plate 102;

[0070] The size of the middle insulation layer 103 matches the size of the inner steel plate 101;

[0071] The edge portion of the outer steel plate 102 extends to the outer side of the middle insulation layer 103 and the inner steel plate 101 to form a mounting portion 104; the width of the mounting portion 104 is at least 100 mm.

[0072] Preferably, both sides of the middle insulation layer 103 of this embodiment are connected to the inner steel plate 101 and the outer steel plate 102 respectively by adhesive fixing;

[0073] The thickness of the inner insulation layer 11 is not less than the thickness of the spliced ​​outer insulation steel plate structure 1 , and the inner insulation layer 11 is adhered and fixed to the inner steel plate 101 facing the indoor side.

[0074] Preferably, the edge of the inner steel plate 101 of this embodiment is provided with an edge seal 105 bent toward the outer steel plate 102;

[0075] The end of the edge seal 105 is connected to the outer steel plate 102 .

[0076] The inner steel plate 101 of the present embodiment can be designed to have a structure with an edge sealing 105, the purpose of which is to be able to seal the middle insulation layer 103 inside. At the same time, the edge sealing 105 of the present embodiment may also be omitted. During the design, it is only necessary to ensure that the size of the outer steel plate 102 is larger than the inner steel plate 101 and the middle insulation layer 103 so that its edge is formed into the installation part 104 to meet the needs of later splicing.

[0077] The installation parts 104 of adjacent spliced ​​external insulation steel plate structures 1 are close to each other, and installation space is reserved between adjacent installation parts 104; the I-shaped insulation connector 2 passes through the installation space and partially extends to the inner surface of the installation part 104; the I-shaped insulation connector 2 and the installation part 104 are assembled and fixed by welding or bolts 3.

[0078] In order to realize the connection of adjacent spliced ​​external insulation steel plate structures 1, this embodiment adopts an I-shaped insulation connector 2 as the connection structure between the two. Specifically, the I-shaped insulation connector 2 of this embodiment includes:

[0079] Outer wing 201 and inner wing 202; and

[0080] A connecting portion 203 connected between the outer wing portion 201 and the inner wing portion 202;

[0081] The width of the outer wing 201 is smaller than the width of the inner wing 202, and the width of the inner wing 202 matches the distance between the inner steel plates 101 of the adjacent spliced ​​external insulation steel plate structures 1;

[0082] The outer wing portion 201 overlaps the outer surface of the adjacent mounting portion 104;

[0083] The outer side surface of the connecting portion 203 and the surface of the inner wing portion 202 are both adhered and fixed with a heat-insulating layer 204 .

[0084] This embodiment further defines the structure of the I-shaped thermal insulation connector 2, which is an integrally formed steel structure, including an outer wing 201, an inner wing 202 and a connection 203; wherein the outer wing 201 overlaps the outer surface of the installation portion 104, the inner wing 202 is arranged between adjacent inner steel plates 101 to fill the space, and the connection 203 passes through the installation space. Finally, in order to ensure the thermal insulation effect of the installation area, the thermal insulation layer is pasted at the corresponding position and pressed between the steel plates.

[0085] When the I-shaped thermal insulation connector 2 is connected to the mounting portion 104 by means of bolts 3 , both the outer wing portion 201 and the mounting portion 104 of the I-shaped thermal insulation connector 2 are provided with threaded holes; the outer wing portion 201 and the mounting portion 104 are assembled and fixed by means of bolts 3 .

[0086] The bolt 3 is provided with a rubber washer 301 .

[0087] In addition, as an extended implementation method, a waterproof layer can be laid on the surface of the corresponding insulation layer in this embodiment, or a waterproof layer can be laid on the outside of the spliced ​​external insulation steel plate structure 1.

[0088] As an extended implementation method, the above embodiment is limited by the spliced ​​external insulation steel plate structure 1, and when the steel structure roof structure spliced ​​by the spliced ​​external insulation steel plate structure 1 is applied to a steel structure factory building, the steel structure roof 10 has a support beam 11;

[0089] The spliced ​​external insulation steel plate structure 1 located outside the steel structure roof 10 is connected to the support beam 11 , and the end of the internal insulation layer 12 is in contact with the support beam 11 .

[0090] The spliced ​​external insulation steel plate structure 1 matched with the support beam 11 is welded and fixed with a mounting plate 4; the mounting plate 4 is configured as a bending structure, and the mounting plate 4 includes:

[0091] A first mounting portion 401 and a second mounting portion 402;

[0092] The first mounting portion 401 is welded and fixed to the lower surface of the inner steel plate 101 of the spliced ​​external insulation steel plate structure 1;

[0093] The second mounting portion 402 extends toward the side of the support beam 11 and abuts against the support beam 11;

[0094] The second mounting portion 402 is fixed to the support beam 11 by welding or by bolt assembly.

[0095] The present embodiment further refines the connection structure between the steel structure roof 10 and the support beam 11. Since a spliced ​​external insulation steel plate structure 1 is adopted, a group of spliced ​​external insulation steel plate structures 1 matched with the support beam 11 needs to consider the installation and fixation with the support beam 11. Compared with the traditional welding fixation or connecting part connection, the present embodiment adds a mounting plate 4, and the mounting plate 4 is connected to the inner steel plate 101 through the first mounting part 401, and is connected to the support beam 11 through the second mounting part 402, thereby improving the overall installation stability and the load resistance capacity.

[0098] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
