Description

Technical Field

[0001] The utility model relates to the technical field of roof equipment foundations in transformer substations and converter stations, and more specifically to a waterproof structure for the foundation of transformer substation roof equipment. Background Art

[0002] The roofs of buildings in substations and converter stations usually need to be arranged with various equipment foundations. The equipment foundations are generally made of concrete piers protruding from the roof. The existence of the equipment foundations seriously affects the laying of roof waterproofing membranes. The membranes on the equipment foundations need to be spliced ​​and covered. When the foundations are connected by bolts, the membranes also need to be penetrated. Therefore, the spliced ​​and covered joints and the bolt penetration points are exposed to wind, sun and rain for a long time, and often aging, cracking and other problems will occur, causing the roof waterproofing to fail and reducing the service life of the building roof waterproofing. Severe roof leakage will cause damage to the internal equipment of the building and the substation to stop operating.

[0003] Therefore, it is very necessary to develop a waterproof structure for the foundation of substation roof equipment. Utility Model Content

[0005] In order to achieve the above object, the technical solution of the utility model is: a waterproof structure of the equipment foundation of the roof of the substation, characterized by comprising an equipment foundation, ears arranged around the top of the equipment foundation, a roof panel arranged around the bottom of the equipment foundation, and a waterproof layer;

[0006] The waterproof layer is laid along the roof panel, the equipment foundation, and the contact point between the equipment foundation and the cantilever.

[0007] In the above technical solution, the equipment foundation, the cantilever and the roof panel are cast in situ as a whole, and the cantilever has a height of 100 mm and a width of 80 mm.

[0008] In the above technical solution, a slope adjustment mortar layer is provided on the equipment foundation and the top of the lug, and the slope adjustment mortar layer is high in the middle and low around.

[0009] In the above technical solution, a thermal insulation layer and a rigid protective layer are sequentially arranged on the waterproof layer at the roof panel.

[0010] In the above technical solution, the waterproof layer at the connection between the equipment foundation and the roof panel is the turned-up portion of the waterproof layer, and the insulation layer and the rigid protective layer are caulked with the turned-up portion of the waterproof layer by polyurethane sealant.

[0011] In the above technical solution, an additional waterproof layer is provided between the equipment foundation and the waterproof layer.

[0012] In the above technical solution, the additional waterproof layer extends horizontally outward from the equipment foundation to the roof panel, with an extension length of not less than 250mm. The additional waterproof layer is a 3mm thick modified asphalt waterproof membrane; the waterproof layer is composed of a 2mm thick polymer modified asphalt waterproof coating and a 3mm thick modified asphalt waterproof membrane.

[0013] In the above technical solution, the waterproof layer and the additional waterproof layer located at the connection between the ear and the top of the equipment foundation are fixed to the side of the equipment foundation by self-tapping screws with waterproof washers, and the outer side of the waterproof washers and self-tapping screws are caulked with polyurethane sealant.

[0014] In the above technical solution, fixing bolts are provided on the top of the equipment foundation.

[0015] In the above technical solution, a finished drip line is provided at the positive corner of the bottom of the ear.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1) The waterproof layer of the present invention does not need to be spliced ​​and covered on the top of the foundation, but only needs to be turned up to the connection between the ear and the top of the foundation, which reduces the construction difficulty of the waterproof construction unit and saves construction time.

[0018] 2) The fixing bolts of the equipment foundation of the utility model do not need to penetrate the waterproof layer and the additional waterproof layer, and there is no situation where the waterproof layer is damaged, and the waterproof effect and reliability are significantly improved.

[0019] 3) The utility model sets a finished drip line at the positive corner of the bottom of the ear, which can effectively drip rainwater on the top surface of the equipment foundation to the roof panel through the finished drip line, preventing rainwater from entering the closing part of the end of the waterproof membrane, and effectively improving the waterproof effect.
