Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building structure and relates to a thermal insulation structure, specifically a thermal insulation installation structure for a cold storage ceiling. Background Technology
[0002] Cold storage refers to an environment created artificially, where the temperature and humidity differ from the outside. It is a constant-temperature and constant-humidity storage facility for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific experiments. Food cold storage is a building used for freezing and refrigerating food. It maintains a certain low temperature inside the storage room through artificial refrigeration. To reduce the transfer of external heat, the floor, walls, and roof of the cold storage are covered with a certain thickness of moisture-proof and air-proof layer and heat insulation layer.
[0003] Chinese utility model patent application number 202321946543.3 discloses a cold storage roof insulation structure, including a roof foundation surface. Multiple L-shaped steel plates are fixed to the bottom surface of the foundation surface using expansion bolts. Circular steel hangers are installed on the outer surfaces of the right-angled sides of the L-shaped steel plates. Multiple square tube keels are connected to the ends of the circular steel hangers. An outer protective color steel plate is installed on the bottom surface of the square tube keels. A polyurethane insulation layer is formed by layered spraying on the upper surface of the skeleton mesh. A thermal break bridging protrusion is installed at the junction of the polyurethane insulation layer and the circular steel hangers. This cold storage roof insulation structure allows for the direct installation of the square tube keels and outer protective color steel plates from the cleaned roof surface, followed by the spraying of the polyurethane insulation layer, without removing the existing roof putty, thus improving construction progress. However, such cold storage roof insulation structures have large gaps at the junction with the walls, affecting the insulation effect inside the cold storage; moreover, the polyurethane insulation layer is easily torn by rodents and insects, affecting its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 4 The cold storage ceiling insulation installation structure shown mainly includes hangers 1, polyurethane sandwich panels 2, panel head suspension structure 4, panel in-slab suspension structure 5, and polymer mortar layer 6, etc.
[0025] There are multiple hanger rods 1, the specific number of which is conventionally selected based on the specific working area. The upper ends of these hanger rods 1 are installed on the cold storage ceiling 1' or / and the hanging beams 2' of the cold storage ceiling 1'. Due to different installation positions of their upper ends, the length of the hanger rods 1 may also be different to ensure that the installed polyurethane sandwich core is in a horizontal state. For example, if the top of a cold storage has main beams and secondary beams, the upper ends of the hanger rods 1 are connected to the main beams and secondary beams respectively. The hanger rods 1 use existing conventional Φ14mm diameter suspension rods, with a main beam suspension point spacing of 2m and a secondary beam suspension point spacing of 1.5m. The hanger rods 1 are used to ensure that the cold storage ceiling is at the designed ceiling height.
[0026] There are multiple polyurethane sandwich panels 2, the specific number of which is conventionally selected according to the specific working area; they are connected to the lower ends of multiple hangers 1 through the panel head hoisting structure 4 and the panel middle hoisting structure 5; that is, the middle part of each polyurethane sandwich panel 2 is connected to the lower ends of some hangers 1 through the panel middle hoisting structure 5, and its edge is connected to the lower ends of some hangers 1 through the panel head hoisting structure 4.
[0027] Specifically, the panel hoisting structure 4 includes turnbuckles 41 installed at the lower end of the lifting rods 1 (one or more lifting rods 1), steel plate parts 43 connected to the lower end of the turnbuckles 41, T-shaped aluminum keels 44 fixed to the steel plate parts 43 for supporting two adjacent polyurethane sandwich panels 2 (the fixing here can be done using existing conventional methods, such as welding), and multiple first pop rivets 45 connecting the T-shaped aluminum keels 44 and the polyurethane sandwich panels 2. Thus, the polyurethane sandwich panels 2 are installed in a horizontal position by the cooperation of the lifting rods 1, turnbuckles 41, steel plate parts 43 and T-shaped aluminum keels 44, and the polyurethane sandwich panels 2 and the T-shaped aluminum keels 45 are used to firmly connect the polyurethane sandwich panels 2 and the T-shaped aluminum keels 44 together (at this time, the first pop rivets 45 are inserted into the polyurethane sandwich panels 2 through the T-shaped aluminum keels 44).
[0028] In this embodiment, the plate head hoisting structure 4 also includes a connecting hook 42 installed at the lower end of the turnbuckle 41. The upper part of the steel plate 43 is connected to the connecting hook 42 through a through hole, thereby indirectly realizing the connection between the turnbuckle 41 and the steel plate 43. The panel hoisting structure 4 also includes a limiting baffle 47 formed on the side of the steel plate 43 (usually formed by integral molding or welding and other conventional methods) that cooperates with the T-shaped aluminum keel 44 to clamp two adjacent polyurethane sandwich panels 2 (i.e., limiting baffles 47 are formed on the two sides of the steel plate 43 perpendicular to it, so that the distance between the limiting baffle 47 and the T-shaped aluminum keel 44 is just equal to the thickness of the polyurethane sandwich panel 2, thereby using the limiting baffle 47 and the T-shaped aluminum keel 44 to clamp the polyurethane sandwich panel 2) and multiple second pull rivets 48 connecting the limiting baffle 47 and the polyurethane sandwich panel 2, i.e., the second pull rivets 48 are inserted into the polyurethane sandwich panel 2 through the limiting baffle 47, so that the polyurethane sandwich panel 2 is firmly installed between the limiting baffle 47 and the T-shaped aluminum keel 44.
[0029] The platen head lifting structure 4 also includes a PVC sleeve 46 sleeved outside the turnbuckle 41 and polyurethane filler inside the PVC sleeve 46. Preferably, the PVC sleeve 46 extends to sleeve outside the steel plate 43 (specifically, the dimensions of the PVC sleeve 46 are Φ110mm and 300mm in height, and the dimensions of the steel plate 43 are 50×150×5mm). In this way, the polyurethane filler can completely wrap the turnbuckle 41, the connecting hook 42 and part of the steel plate 43, thereby greatly improving the stability and load-bearing capacity of the platen head lifting structure 4 and preventing it from shaking during use.
[0030] The slab hoisting structure 5 includes a C-shaped light steel keel 51 installed at the lower end of the hoisting rod 1 (one or more hoisting rods 1, not connected to the aforementioned slab head hoisting structure 4), an angle steel 52 fixed to the side of the C-shaped light steel keel 51 (the fixing can be done using existing conventional methods, such as welding), and multiple nylon bolts 53 connected to the angle steel 52 and penetrating through the polyurethane sandwich panel 2. That is, the nylon bolts 53 penetrate through the polyurethane sandwich panel 2 and are connected to the angle steel 52, so that the polyurethane sandwich panel 2 is firmly connected between the nylon bolts 53 and the angle steel 52.
[0031] The polymer mortar layer 6 is coated on the upper surface of multiple polyurethane sandwich panels 2, typically covering the entire upper surface of the polyurethane sandwich panels 2. This improves the thermal insulation effect of the polyurethane sandwich panels 2 to a certain extent and effectively prevents rodent and insect damage, providing excellent protection for the polyurethane sandwich panels 2. The thickness of this polymer mortar layer 6 is 2~5mm, and existing conventional types such as WY-1, WY-2, WY-3, and WY-4 can be used.
[0032] The aforementioned cold storage ceiling insulation installation structure also includes a polyurethane spray coating 3, which is formed between the polyurethane sandwich panel 2 and the polymer mortar layer 6. The specific thickness can be conventionally selected according to actual needs, typically involving layered spraying of polyurethane to the designed thickness to form the polyurethane spray coating 3 (in this embodiment, the polyurethane spray coating 3 preferably extends to form an integral layer with the aforementioned polyurethane filler, which improves construction convenience). The polyurethane spray coating 3 also extends to the gap between the polyurethane sandwich panel 2 and the wall 3' (e.g.,...). Figure 4 As shown in the diagram, and in the gaps between two adjacent polyurethane sandwich panels 2, this eliminates cold bridges at the junction of the ceiling and wall 3' and the connection points of the two polyurethane sandwich panels 2, thus achieving better insulation. Spraying polyurethane onto the polyurethane sandwich panels 2 does not affect the aesthetic appearance inside the warehouse, but significantly improves the insulation effect. In this embodiment, as... Figure 4 As shown, polyurethane sandwich panels 2 are usually installed on the inner side of the wall 3' of the cold storage. The outermost polyurethane sandwich panel 2 (horizontally set and used for the ceiling) can be directly placed on the upper end of the polyurethane sandwich panel 2 on the inner side of the wall 3' (reducing the corresponding panel head hanging structure 4). The patch is removed at the overlap, and corner protectors 7 are set at the inside corner of the overlap to improve the heat preservation effect.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
