Description

Technical Field

[0001] The utility model relates to the field of auxiliary buildings, in particular to a special assembled concrete integrated auxiliary building for a transformer substation. Background Art

[0002] Substation unit auxiliary room refers to the modular auxiliary room that is used to meet the production and living needs of substation duty and power supply.

[0003] The modular design and factory-produced integrated building materials vary from location to location. Most buildings utilize steel structures, while others utilize brick-concrete frame structures. While small, these fully-equipped buildings require a long construction period, typically around 50 days. We are designing a new type of prefabricated concrete structure for an integrated auxiliary building (guardhouse). The entire building is manufactured, assembled, and decorated in a factory, then transported to the site for installation. Once the pre-buried plumbing is connected, it's ready for use.

[0004] However, the structures of some auxiliary buildings are too large, and the selected vehicles have fixed transportation capacity, or road transportation does not comply with the national regulations on large-scale transportation, making the auxiliary buildings inconvenient to transport. Therefore, a prefabricated concrete integrated auxiliary building is needed. Utility Model Content

[0024] Please refer to Figure 1-8 As shown, an embodiment of the present application provides a technical solution: a special prefabricated concrete integrated auxiliary room for a substation, including a first auxiliary room 1 and a second auxiliary room 2. Both the first auxiliary room 1 and the second auxiliary room 2 include a plurality of entrance doors 11 and an internal residential space formed by a wall 12, a floor 13 and a roof panel 14. The residential space formed by the first auxiliary room 1 and the second auxiliary room 2 is divided into a guard room 51, a bathroom 52, a pantry 53, a duty room 54 and a toilet 55, and the guard room 51, the bathroom 52, the pantry 53, the duty room 54 and the toilet 55 are all provided with separate entrance doors 11, and are connected by filling mortar 31 between the first auxiliary room 1 and the second auxiliary room 2.

[0025] By dividing the auxiliary room into two or more separate parts, it is convenient for the transportation of the auxiliary room. Connecting the first auxiliary room 1 and the second auxiliary room 2 by using filling mortar 31 is beneficial to saving cementitious materials, facilitating construction and saving on-site installation time.

[0026] Mortar is an adhesive substance used for bricklaying in construction, made by mixing a certain proportion of sand and cementitious materials such as cement, lime paste, clay, etc. with water, also called grout, also known as mortar.

[0027] In a preferred solution, a waterstop rubber strip 32 is covered on the outer surface of the filling mortar 31 between the first auxiliary room 1 and the second auxiliary room 2, and a waterproof coil 33 is covered on the waterstop rubber strip 32. The waterproof coil 33 is detachably connected to the first auxiliary room 1 and the second auxiliary room 2.

[0028] Waterproof coils are mainly used for building walls, roofs, tunnels, roads, landfills, etc., to play a role in resisting external rainwater and groundwater seepage. They are a kind of flexible building material product that can be rolled into a roll. As a leak-free connection between the project foundation and the building, it is the first barrier for the waterproofing of the entire project and plays a crucial role in the entire project. The products mainly include asphalt waterproof coils and polymer waterproof coils.

[0029] The waterproof coiled material 33 can be pasted on the wall surfaces of the first auxiliary room 1 and the second auxiliary room 2 or, after punching holes, installed with screws fixed to the wall surfaces.

[0030] In a preferred embodiment, a parapet wall 4 is further provided around the upper periphery of the roof slab 14. Embedded steel bars 41 passing through the roof slab 14 are provided at corresponding positions of the wall body 12, and first threaded blind holes 42 are provided at corresponding positions of the parapet wall 4. The reserved embedded steel bars 41 are inserted into the first threaded blind holes 42, and grout is poured into the first threaded blind holes 42 to connect the parapet wall 4 to the wall body 12.

[0031] The parapet wall, also known as the granddaughter wall, is a low wall around the roof of a building. In addition to maintaining safety, its main function is to apply a waterproof brick capping at the bottom to prevent the waterproof layer from seeping water or the roof rainwater from overflowing.

[0032] In a preferred embodiment, lifting points 6 are provided around the upper periphery of the first auxiliary room 1 and the second auxiliary room 2.

[0033] In a preferred embodiment, the lifting point 6 is a threaded steel sleeve 61 vertically embedded upward in the roof slab 14. A splayed steel bar 62 passes through the lower part of the threaded steel sleeve 61, and U-shaped steel bars 64 extending downward to the lower part of the wall body 12 are wound around the upper surface periphery of the threaded steel sleeve 61. The U-shaped steel bar 64 includes a U-shaped part 641 and legs 642 perpendicular to the U-shaped part. A straight bar 63 passes through the bend of the U-shaped part 641 and the legs 642.

[0034] When lifting, the lifting ring screw can be inserted into the threaded steel sleeve 61.

[0035] In a preferred embodiment, the waterstop rubber strip 32 is a water-swelling waterstop strip.

[0036] The water-swelling waterstop strip is a unique new rubber product, which is a general term for putty-type waterstop strips and product-type waterstop strips with water-swelling properties.

[0037] In a preferred embodiment, a connecting plate 34 is further provided below the first auxiliary room 1 and the second auxiliary room 2.

After the hoisting is completed, align the holes on the connecting plate 34 with the holes of the positioning device 7, fix the auxiliary room, and then remove the positioning device 7;

[0042] When connecting the connecting plate 34 to the positioning device 7, leveling is required. Before hoisting and positioning, first check the axis, elevation, flatness of the foundation beam and the installation of the positioning device according to the design drawing. After verification, then hoist the auxiliary building.

[0043] In the third step, connect the first auxiliary building 1 and the second auxiliary building 2 to the foundation beam 8. Stick a water-stop rubber strip 32 on the outside between the docking joints of the first auxiliary building 1 and the second auxiliary building 2. Install a waterproof coiled material 33 outside the water-stop rubber strip 32, and fill mortar 31 inside the docking joints of the first auxiliary building 1 and the second auxiliary building 2.

[0044] In the fourth step, insert the first threaded blind hole 42 of the parapet wall 4 into the reserved embedded steel bar 41, inject structural adhesive into the first threaded blind hole 42, and then treat the joint surface between the parapet wall 4 and the roof slab 14 with waterproof glue.

[0045] In a preferred solution, the positioning device 7 is a space surrounded by a plurality of L-shaped 71 and a plurality of linear 72 positioning plates. The thickness of the L-shaped 71 and the linear 72 plates is 20 mm. Holes corresponding to the connecting plate 34 are provided on the L-shaped 71 and the linear 72 plates.
