Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a ground ridge wall overhead plate structure and a transformer station. Background Art

[0002] When constructing the ridge wall and the overhead slab, the invention patent application with application publication number CN 109958187 A discloses a feasible implementation method, in which the ridge wall and the overhead slab are cast together with reinforced concrete structure.

[0003] In this kind of structure, the large load of the structure itself will cause the lower floor slab or basement ceiling to be thicker and have larger reinforcement. Casting them together will cut off the frame columns of the main structure, turning the frame columns into ultra-short columns that are prone to brittle failure, affecting the safety of the main structure and taking a long time.

[0004] In another implementation, the ridge wall adopts a brick wall structure, and the overhead slab adopts a cast-in-place slab separated from the main structure. The ridge wall needs to be designed with lintels, structural columns and ring beams at the reserved holes to reinforce the wall. There are a large number of them, and the main reinforcement of the structural columns needs to be designed and reserved in advance. These secondary structures can only be constructed after the main structure is completed, which is inconvenient. In addition, the location of the pipeline needs to be changed later. The distribution of steel bars in the concrete substrate needs to be measured by metal detectors, and then holes are drilled and steel bars are planted. After the steel bars are planted, pull-out tests need to be done on site, which prolongs the construction period. Utility Model Content

[0027] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0028] In the description of the scheme, it should be noted that the terms "center", "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] The ridge wall overhead plate structure disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 , Attachment Figure 2 As shown, it includes a ridge wall 100 and an overhead slab layer 200 erected on the ridge wall 100. The number, position and material of the ridge wall 100 can be designed as needed. In this embodiment, the ridge wall 100 is a brick wall, and the ridge wall 100 includes parallel half-brick walls 110 and a brick wall 120. The half-brick walls 110 are two and distributed on both sides of the brick wall 120. The overhead slab layer 200 is arranged between each of the half-brick walls 110 and the brick wall 120.

[0030] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3As shown, the overhead slab 200 includes a group of beam-slab units 210, and the beam-slab units 210 include two parallel beams 211 and a plate 212 connected between the two beams 211. The two beams 211 and the plate 212 can be prefabricated parts cast in one piece. The beam 211 is provided with a group of reserved through holes 213 extending along the axial direction thereof. The number of the reserved through holes on each beam 211 can be designed as required. Preferably, the number of each reserved through hole 213 is four and they are distributed in a square shape. The reserved through holes 213 extend along the axial direction of the beam 211. A group of beam-slab units 210 are connected in series through the steel bars 220 passing through the reserved through holes 213.

[0031] Furthermore, the plate body 212 is a one-way plate. Except for the beam-slab unit 210 on one side, the spans of the other beam-slab units 210 are the same. Specifically, the short side spans of the other beam-slab units 210 are 1 m. This can effectively realize batch processing of the beam-slab units 210 and facilitate manufacturing.

[0032] During the specific construction, after all partition walls, trenches and pipelines are constructed, the ridge wall 100 is obtained by brick masonry, and a group of beam-slab units 210 are placed on the half-brick wall 110 and the brick wall 120, and then connected by steel bars 220 after the on-site layout is completed.

[0033] Furthermore, the gaps between the beam-slab units 210 are filled with cement mortar, preferably M7.5 cement mortar. Meanwhile, the gaps between the steel bars 220 and the reserved line holes are filled with cement mortar.

[0034] Further, in order to facilitate the wiring, it is usually necessary to set a reserved wire hole on the ridge wall 100 for wiring. In this embodiment, when the reserved wire hole is set on the ridge wall 100, as shown in the attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 As shown, the overhead slab layer 200 further includes two beam units 230 corresponding to the positions of the reserved wire holes on the ridge wall 100. The two beam units 230 are arranged on the two ridge walls 100 where the overhead layer is located. An opening 240 is formed between the two beam units 230 to facilitate subsequent maintenance. A cover plate 250 is arranged on the two beam units 230, and one side of the cover plate 250 can be hinged on the beam unit 230. Correspondingly, the beam unit 230 is also provided with a reinforcing bar hole 231 extending along the axial direction of the beam unit 230. The reinforcing bar hole 231 matches the reserved through hole 213 on the beam body 211 of the beam-slab unit 210. The beam unit 230 and the beam-slab unit 210 are also connected in series through the steel bar 220.

[0035] Of course, in another embodiment, instead of opening holes on the ridge wall 100 , the reserved wire holes are provided on the beam unit 230 , and the reserved wire holes extend horizontally and perpendicular to the axial direction of the beam unit, thereby effectively ensuring the structural stability of the ridge wall 100 .

[0037] This embodiment discloses a substation, as shown in the attached Figure 1 , Attachment Figure 5 As shown, it includes any of the above-mentioned ridge wall overhead plate structures. The ridge wall 100 is located inside the retaining wall 300, and the retaining wall 300 is pre-embedded with curtain wall fixing parts 400, and the curtain wall 500 is arranged on the curtain wall fixing parts. The ridge wall or beam unit close to the substation cable trench is provided with steel pipes for wiring.

[0038] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
