Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor assembled building component design and relates to an outdoor assembled transformer fire wall. Background Art

[0002] According to fire prevention requirements, a firewall needs to be set up between outdoor transformers. At present, the traditional conventional firewall method is reinforced concrete or block wall structure, but in remote areas or complex terrain construction, and when the transformer has been installed and the firewall is constructed, this structural form has the following problems:

[0003] (1) Difficulty in transporting construction materials. Due to geographical location and complex terrain, it is difficult to transport heavy construction materials such as large amounts of concrete and blocks.

[0004] (2) Impact on transformers: Large-scale construction, masonry, and open flame welding of steel bars at the construction site have an impact on the installed transformers.

[0005] (3) Poor decorative effect. The outer surface of the fire wall is generally made of concrete, which makes the overall appearance unsightly.

[0006] (4) High project cost. The large amount of reinforced concrete and the need for auxiliary construction materials such as formwork and scaffolding increase the project cost. Utility Model Content

[0007] The purpose of the utility model is to provide an outdoor assembled transformer fire wall in view of the problems existing in the existing common technologies and practices. It is all prefabricated and assembled components, with light steel keels as the skeleton, fireproof rock wool board and fireproof gypsum board as the basic wall of the fire wall, which meets the fire resistance limit requirements of the transformer fire wall; on both sides of the basic wall, a layer of polyvinyl chloride air barrier is laid, and then a layer of metal corrugated steel plate is laid on the outermost side, which plays a role in waterproofing and air-isolating the internal rock wool board and gypsum board and protecting them from external impact.

[0008] To achieve the above-mentioned purpose, the utility model provides an outdoor assembled transformer fire wall, which is characterized in that: a light steel keel is laid in the area where a fire wall is required to be set around the transformer, and a fireproof rock wool board is filled in the gap of the light steel keel; a double-layer fireproof gypsum board is laid on both sides of the fireproof rock wool board and fixed to the light steel keel with self-tapping screws; a full-length square steel pipe is connected to the light steel keel with self-drilling screws in the height direction to fix the outermost metal corrugated steel plate; a layer of polyvinyl chloride air barrier layer is laid on the outer side of the fireproof gypsum board; finally, another layer of metal corrugated steel plate is laid on the outermost side to protect and waterproof the entire wall, and the metal corrugated steel plate is fixed to the square steel pipe by rivets. The use of the fireproof rock wool board and the double-layer fireproof gypsum board can meet the fire resistance limit requirements required for the fire wall; the polyvinyl chloride air barrier layer and the metal corrugated steel plate play a role in waterproofing and air-isolating the internal rock wool board and gypsum board and resisting external force impact.

[0009] Furthermore, the light steel keel is in a "C" shape. In order to increase the stability and strength of the wall, two "C"-shaped light steel keels are fixed back to back with bolts to form a whole.

[0010] Furthermore, the thickness of the fireproof rock wool board is 75 mm.

[0011] Furthermore, the thickness of the fireproof gypsum board is 12 mm.

[0012] Furthermore, the overall length of the square steel tube along the height direction is 25 mm×25 mm.

[0013] Positive effects of the utility model: the utility model can be applied to the firewall of the outdoor transformer.

[0014] (1) All components are prefabricated and assembled, with simple structure, easy construction and fast construction progress. This solves the problem of difficulty in transporting heavy building materials such as conventional building wall materials and concrete in remote areas or complex terrain.

[0015] (2) Work can be done on site without the need for on-site fire; especially when the transformer has been installed and construction is being carried out behind a firewall, the impact of large-scale construction, masonry, and open flame welding of steel bars on the installed transformer can be reduced.

[0016] (3) The wall is light in weight, the wall foundation of the fire wall is simple, and the amount of reinforced concrete used is reduced.

[0017] (4) The surface of metal corrugated steel sheet is flat and smooth, and various colors can be freely selected. The decoration can be formed in one time, and the outdoor effect is beautiful. BRIEF DESCRIPTION OF THE DRAWINGS
