Description

Technical Field

[0001] The utility model belongs to the technical field of livestock breeding facilities, and particularly relates to a heat-insulating and sealing roof structure for pig houses. Background Art

[0002] With the progress of technology and the rapid development of the livestock and poultry breeding industry, the production capacity and pork quality of intensive pig farming, which is closely related to people's lives, have attracted more and more attention. Traditional pig house designs often neglect the importance of heat insulation and sealing, resulting in an unsuitable growth environment for pigs under extreme climate conditions. This not only affects the health and growth rate of pigs but also increases breeding costs because additional energy is required to regulate the temperature inside the pig house.

[0003] Currently, the heat insulation measures for pig house roofs mainly rely on traditional heat insulation materials, such as polyurethane foam spraying. Although these materials have a certain heat insulation effect, their construction process is cumbersome and the requirements for the construction environment are relatively strict. In addition, during long-term use, these materials are prone to aging and peeling, which reduces the durability of the heat insulation effect. At the same time, polyurethane foam releases harmful substances during the manufacturing process, which may pose potential risks to the environment and animal health.

[0004] Therefore, it is particularly urgent to develop a new type of heat-insulating and sealing structure for pig house roofs. Content of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a heat-insulating and sealing roof structure for pig houses, which has good heat insulation performance, is more stable and environmentally friendly during long-term use, and can meet the needs of the sustainable development of modern animal husbandry. At the same time, this structure is easy to construct and maintain, and has a lower cost.

[0006] To solve the above technical problems, a technical solution adopted by the utility model is:

[0007] A heat-insulating and sealing roof structure for pig houses, comprising a purlin layer, a stainless steel wire mesh layer, a double-sided adhesive layer, a flame-retardant sealing film layer, a heat-insulating cotton layer, a roof panel support and a roof panel, which are arranged in sequence from bottom to top. The purlin layer includes a plurality of purlins arranged in a row. The double-sided adhesive layer is arranged along the purlins. One side of the double-sided adhesive layer fixes the wire mesh layer on the upper surface of the purlins, and the other side is connected to the flame-retardant sealing film layer. The roof panel support is fixedly connected to the purlins through self-tapping screws for brackets, and the roof panel is installed on the upper surface of the roof panel support;

[0008] The flame-retardant sealing film layer includes a plurality of flame-retardant sealing film sheets. A lapping portion is arranged between adjacent flame-retardant sealing film sheets. The lapping portion is provided with an adhesive layer. The lapping portion is folded and sewn with sewing threads.

[0009] Furthermore, the mesh size of the stainless steel wire mesh layer is 150 mm × 150 mm, and the wire diameter of the iron wire in the stainless steel wire mesh layer is 1 mm.

[0010] Furthermore, the double-sided adhesive layer is a double-sided foam tape layer, and the width of the double-sided foam tape layer is 50 mm, and the thickness is 2 mm.

[0011] Furthermore, the length of the flame-retardant sealing diaphragm is 100 mm, the width is 1200 mm to 1500 mm, and the thickness is 0.2 mm to 0.5 mm. It has high sealing performance, is resistant to aging for 30 years, and has high strength.

[0012] Furthermore, the thermal insulation cotton layer is a glass wool layer, and one side of the thermal insulation cotton layer facing the roof panel has an aluminum foil layer.

[0013] Furthermore, the height of the roof panel bracket is 80 mm. The sheet metal thickness of the roof panel bracket is 1.5 mm.

[0014] Furthermore, the bracket self-tapping screw is installed at the bottom of the roof panel bracket, penetrates through the thermal insulation cotton layer, the flame-retardant sealing film layer, the wire mesh layer and the double-sided adhesive layer, and is connected to the purlin.

[0015] Furthermore, the width of the overlapping part is 50 mm, and the thickness of the bonding layer is 2 mm.

[0016] Furthermore, a polyurethane filling layer is provided at the joint between the roof and the pigsty wall.

[0017] The beneficial technical effects of the present utility model are:

[0018] By adopting a multi-layer structure design, the efficient heat preservation and sealing of the pigsty roof are realized, the heat exchange inside and outside the pigsty is effectively reduced, and a more stable and suitable growth environment is provided for pigs. The multi-layer structure includes a stainless steel wire mesh layer, a double-sided adhesive layer, a flame-retardant sealing film layer, a thermal insulation cotton layer, etc. The combination of these materials not only improves the heat preservation performance, but also enhances the sealing and durability of the roof. The setting of the stainless steel wire mesh layer can support the heat preservation and sealing layer, effectively preventing the sagging, damage and displacement of the heat preservation and sealing materials. The use of the double-sided adhesive layer and the flame-retardant sealing film layer ensures the sealing of the roof and prevents unfiltered external air from entering the roof. The use of the thermal insulation cotton layer further improves the heat preservation effect, and the aluminum foil layer of the thermal insulation cotton layer reflects part of the heat, improving the heat preservation efficiency. In addition, the polyurethane filling layer is used to seal the joint between the roof and the pigsty wall, further improving the heat preservation and sealing performance of the pigsty and preventing the intrusion of cold air and moisture.

At the same time, it is convenient for later inspection and repair, improving the service life of the pigsty, and effectively reducing the release of harmful substances. While improving the heat preservation performance of the pigsty, the present utility model also protects the environment and the health of animals. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0034] This specific embodiment discloses in detail a heat preservation and sealing structure for the roof of a pigsty, as Figures 1 to 4 shown

[0035] It includes a purlin layer 1, a stainless steel wire mesh layer 2, a double-sided adhesive layer 3, a flame-retardant sealing film layer 4, a thermal insulation cotton layer 5, a roof panel support 6, and a roof panel 7 arranged from bottom to top. The purlin layer includes multiple purlins 11 arranged in a row. The double-sided adhesive layer is arranged along the purlins. One side of the double-sided adhesive layer fixes the wire mesh layer on the upper surface of the purlins, and the other side is connected to the flame-retardant sealing film layer. The roof panel support is fixedly connected to the purlins through self-tapping screws 61 for brackets. The self-tapping screws for brackets are installed at the bottom of the roof panel support and penetrate through the thermal insulation cotton layer, the flame-retardant sealing film layer, the wire mesh layer, and the double-sided adhesive layer to be connected to the purlins. The roof panel is installed on the upper surface of the roof panel support;

[0036] The flame-retardant sealing film layer includes multiple flame-retardant sealing film sheets 41. There is a lapping part 42 between adjacent flame-retardant sealing film sheets. The lapping part is provided with an adhesive layer 43. The lapping part is folded and sewn through a sewing thread 44. The width of the lapping part is 50 mm, and the thickness of the adhesive layer is 2 mm.

[0037] In this embodiment, the mesh size of the stainless steel wire mesh layer is 150 mm × 150 mm, and the wire diameter of the iron wire of the stainless steel wire mesh layer is 1 mm. The double-sided adhesive layer is a double-sided foam tape layer. The width of the double-sided foam tape layer is 50 mm, and the thickness is 2 mm. The length of the flame-retardant sealing film sheet is 100 mm, the width is 1200 mm - 1500 mm, and the thickness is 0.2 mm - 0.5 mm. The flame-retardant sealing film sheet has high sealing performance, can resist aging for 30 years, and has high strength. The thermal insulation cotton layer is a fiberglass wool layer. One side of the thermal insulation cotton layer facing the roof panel has an aluminum foil layer 51. The aluminum foil layer can reflect part of the solar radiation and improve the thermal insulation effect. The height of the roof panel support is 80 mm, and the sheet metal thickness of the roof panel support is 1.5 mm.

[0038] A polyurethane filling layer 8 is provided at the joint between the roof and the wall of the pigsty, which further improves the thermal insulation and sealing performance of the pigsty and prevents the intrusion of cold air and moisture.

[0039] Specifically, when installing the roof thermal insulation and sealing structure involved in the present utility model:

[0040] In the first step, first install the roof truss structure and the purlin system. The purlin system can be understood as the above-mentioned purlin layer. Then start to install the roof stainless steel wire mesh. The mesh of the stainless steel wire mesh is a rhombus with a width and length of 150 mm, and the wire diameter of the stainless steel wire mesh is 1 mm.

[0041] In the second step, stick the double-sided foam tape along the purlins, then lay the flame-retardant sealing film sheets, and fix them through the double-sided foam tape. Then install the thermal insulation cotton with the side having the aluminum foil facing up.

[0042] In the third step, install the roof brackets. The self-tapping screws of the brackets are driven into the center of the double-sided foam tape without exceeding the scope of the tape, and then install the roof panels on the roof brackets.

[0043] When laying the flame-retardant sealing film, attach double-sided tape to its edge, then lap and closely adhere to the edge of another flame-retardant sealing film. Fold and seal the overlapping joint, usually using a mechanical sealing method, so as to avoid the situation that the joint will open after a long time.

[0044] The roof brackets and roof panels are also in multiple pieces. After sequential installation, spray polyurethane with a width of 350 mm and a thickness of 50 mm from the wall to the roof direction to prevent unsealing at the junction of the roof and the wall.

[0045] In summary, the structure of the present utility model is easy to construct and maintain, reduces the construction difficulty and cost, is convenient for later inspection and maintenance, improves the service life of the pigsty, and effectively reduces the release of harmful substances. While improving the heat preservation performance of the pigsty, the present utility model also protects the environment and the health of animals.

[0046] After calculation, the cost of using polyurethane foam spraying for heat preservation is 50 yuan per square meter higher than that of this solution. Calculated based on a 30,000-square-meter building area for a 8,000-sow farm in each project, it can save more than 1.5 million yuan.
