Description

Technical Field

[0001] This utility model belongs to the field of cold storage wall structure, specifically relating to a composite wall insulation structure for cold storage. Background Technology

[0002] Cold storage is a type of refrigeration equipment that uses artificial means to create an environment with a different temperature or humidity than the outside. It is also a constant temperature and humidity storage device for items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific experiments.

[0003] Chinese utility model patent application number 202223013666.X discloses an interior partition wall for buildings, including a sandwich panel, a connecting plate, a stainless steel protective sheet, and a base fixed to the foundation by expansion bolts. The base has an installation groove for installing the sandwich panel, which is installed in the groove. The upper part of the connecting plate is bonded to the sandwich panel, and the lower part is bonded to the base. The stainless steel protective sheet covers the outside of the connecting plate and is bonded to it. This structure allows for quick disassembly and assembly without damaging the original sandwich panel, enabling the reuse of the sandwich panel. Furthermore, the base seals the bottom of the sandwich panel, preventing the filler from absorbing moisture and ensuring the wall's thermal insulation performance. However, there is still room for improvement in thermal insulation performance, and the sandwich panel partition wall is easily damaged in the event of a collision. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a composite wall insulation structure for cold storage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a composite wall insulation structure for cold storage, comprising multiple steel structural columns installed between the civil engineering wall and the roof structure and spaced apart; multiple horizontal keels installed between two adjacent steel structural columns and spaced apart; two galvanized angle iron keels installed on the bottom surface of the roof structure and the top surface of the civil engineering wall; color steel plates installed on the two galvanized angle iron keels; multiple first T-shaped wooden piles installed on each of the horizontal keels and extending away from the color steel plates; stainless steel plates installed on the multiple first T-shaped wooden piles; and polyurethane spraying formed between the color steel plates and the stainless steel plates.

[0006] Ideally, the roof structure of the warehouse is a floor slab or a roof beam.

[0007] Ideally, the spacing between two adjacent steel structure columns should be ≤4m.

[0008] Ideally, it also includes multiple second T-shaped wooden piles installed on the surface of the civil engineering wall and flush with the first T-shaped wooden piles, and the stainless steel plate is also installed on the multiple second T-shaped wooden piles.

[0009] Furthermore, it also includes transverse wooden joists installed on each row of the first T-shaped wooden stakes and the second T-shaped wooden stakes, the transverse wooden joists being treated with anti-corrosion, and the stainless steel plates also being installed on the transverse wooden joists.

[0010] Furthermore, it also includes multiple angle steels installed on the two galvanized angle iron keels and spaced apart, the angle steels being parallel to the steel structure columns.

[0011] Ideally, the horizontal keel is a C-shaped steel with the C-shaped opening facing downwards and its side flush with the exterior wall surface.

[0012] Ideally, the sprayed polyurethane is applied in layers to form a layered polyurethane coating to the designed thickness, with each layer being 20-30 mm thick.

[0013] Due to the application of the above technical solutions, this utility model has the following advantages compared with the prior art: The composite wall insulation structure of this utility model for cold storage, by installing steel structural columns, horizontal keels and sprayed polyurethane between the civil engineering wall and the top structure, can reduce the load burden on the cold storage compared to the case of all partition walls, thereby reducing the weight occupied by the stored goods; the insulation effect is better than that of polyurethane sandwich panel partition walls; because its lower part is a civil engineering wall and the upper steel structural columns are tightly connected to the top of the storage, it has good stability. Compared with the problem of easy damage from collisions to sandwich panel partition walls, the compressive strength and structural strength of this wall insulation structure are improved, minor collisions do not affect the wall structure, and it is easy to repair.

[0014] Figure 1 This is a schematic diagram of the composite wall insulation structure for cold storage according to this utility model; Figure 2 This is a cross-sectional view of the composite wall insulation structure for cold storage according to this utility model. Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] like Figure 1 and Figure 2The cold storage composite wall insulation structure shown is installed between the civil engineering wall 1' and the storage roof structure 2' (such as a floor slab or roof beam). Specifically, it includes multiple steel structural columns 1 installed between the civil engineering wall 1' and the storage roof structure 2' and spaced apart; multiple horizontal keels 2 installed between two adjacent steel structural columns 1 and spaced apart; two galvanized angle iron keels 4 installed on the bottom surface of the storage roof structure 2' and the top surface of the civil engineering wall 1'; color steel plates 7 installed on the two galvanized angle iron keels 4; multiple first T-shaped wooden piles 6 installed on each horizontal keel 2 and extending away from the color steel plate 7; stainless steel plates 8 installed on the multiple first T-shaped wooden piles 6; and sprayed polyurethane 9 formed between the color steel plate 7 and the stainless steel plate 8.

[0017] Compared to all-wall cold storage, the aforementioned composite wall insulation structure reduces the load on the cold storage, thereby reducing the weight of stored goods. Its insulation performance is superior to polyurethane sandwich panel walls. Because its lower part is a civil engineering wall and its upper steel structure columns are tightly connected to the top of the storage unit, it possesses excellent stability. Compared to sandwich panel walls, which are easily damaged by impacts, this wall insulation structure has improved compressive strength and structural strength; minor impacts do not affect the wall structure, and it is easy to repair.

[0018] In this embodiment, the spacing between two adjacent steel structure columns 1 is ≤4m. The cold storage composite wall insulation structure also includes multiple second T-shaped wooden piles installed on the wall surface of the civil engineering wall 1' and flush with the first T-shaped wooden piles 6, and stainless steel plates 8 are also installed on the multiple second T-shaped wooden piles.

The spacing is no more than 4m (if there is a structural column, it can be replaced; when there is a capping, the lower part of the steel structure column 1 is fixed to the capping wall beam). The upper part (or top) of the steel structure column 1 is fixed to the floor slab / beam bottom (when the steel structure column 1 is a C-shaped steel, its opening faces the inside of the cold storage, and its back is flush with the outer wall surface of the civil engineering wall 1').

[0020] (2) Horizontal keel 2 shall be installed between the structural column (inside the cold storage) and the adjacent steel structure column 1, as well as between two adjacent steel structure columns 1 (there are two in this application, but the height can be increased according to the application scenario; the specifications can be selected within the following range: C100~200*50~100*1~5mm, such as C140*70*2.5mm; the distance between the two keels is 1m, the C-shaped opening faces down, and the side is flush with the outer wall surface). (3) Set a galvanized angle iron keel 4 on the bottom surface of the warehouse top structure 2' and the top surface of the civil wall 1' respectively (a total of two keels), and set multiple vertical angle steels 3 (such as L20~80*2~5, for example L50*3), with a spacing of 1m, almost flush with the outer wall surface; (4) Fix the color steel plate 7 (the thickness can be selected according to actual needs, such as 0.4~1mm, etc.) on the galvanized angle iron keel 4 (on the side facing the outer wall). (5) Fix multiple first T-shaped wooden piles 6 on the horizontal keel 2 (multiple first T-shaped wooden piles 6 are set at intervals between the top and bottom, and there are two in this application), and fix second T-shaped wooden piles on the wall surface of the civil engineering wall 1' (the length of the second T-shaped wooden piles is made to be consistent with the insulation thickness later), so that the first T-shaped wooden piles 6 and the second T-shaped wooden piles are flush. (6) Apply polyurethane insulation base coat to the inside of the color steel plate in the warehouse, and then apply polyurethane in layers to the designed thickness (each layer is 20-30mm thick). Apply insulation on site. (7) Install horizontal wooden joists 5: Fix the horizontal wooden joists 5 (the specifications can be selected according to actual needs, such as 20~50*20~60mm, for example 30*40mm; already treated with anti-corrosion) to the first T-shaped wooden stakes 6 and the second T-shaped wooden stakes with a nail gun; (8) Install single-layer stainless steel plate 8 with stainless steel self-tapping screws: Fix stainless steel plate 8 to horizontal wooden keel 5 with stainless steel self-tapping screws; (9) Acceptance.
