Abstract
The utility model discloses an underground outdoor wall structure. The thickness of the basement outer wall is flexibly adjusted according to the stress characteristics of the outer wall, the defect that the wall thickness is fixed in the prior art is overcome, meanwhile, structural materials can be saved, and the construction cost is reduced. The utility model discloses according to atress size adjustment wall thickness, the utility model discloses utensil beneficial effect: (1) the ribbed slab is adopted at the positive bending moment of the outer wall, so that the consumption of concrete in a tension area can be reduced. (2) And the local thickened section is adopted at the negative bending moment of the support, so that the rigidity is increased and the reinforcing bar is reduced. (3) Thickness based on the prerequisite adjustment outer wall of component atress, the utility model discloses a material quantity will be less than traditional basement outer wall, and structural rigidity is greater than traditional basement outer wall.
Description
Technical Field
The utility model relates to a basement outer wall, especially a basement outer wall of optimization.
Background
The basement outer wall is under the ground and is influenced by the earth water pressure of the basement. The floor can be used as a support of the basement outer wall, and the calculation model of the basement outer wall is often simplified into a continuous beam model. The force transmission path can be divided into vertical force transmission and horizontal force transmission according to different force transmission paths. As shown in fig. 1-2, in the calculation model of the exterior wall (taking the underground two-storey as an example), the midspan is a positive bending moment, the support is a negative bending moment, and the negative bending moment of the support is larger than the midspan bending moment. In the prior art, the thickness of the outer wall of the basement is the same as that of the outer wall of the basement, and the thickness of the outer wall is not adjusted according to the stress.
Based on this, the utility model designs an underground chamber outer wall structure of adjustable thickness to solve the above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
The utility model provides a new basement exterior wall structure according to the nimble thickness of adjusting the basement outer wall of outer wall atress characteristics, solves among the prior art drawback that the wall is a fixed thickness, can also save structural material simultaneously, reduces construction cost.
The utility model relates to a basement outer wall, include: external wall flat plate, external wall ribbed slab, wall or column, floor, bottom plate. The outer wall flat plate and the outer wall rib plate are arranged between the floor slab and the bottom plate or between the floor slab and the floor slab, and the outer wall rib plate is arranged in the middle of each layer of outer wall.
Preferably, the outer wall flat plate is a conventional rectangular plate, the thickness of the plate is larger than that of the conventional outer wall, and the plate is only arranged at the negative ribs of the support.
Preferably, the external wall rib plates are unidirectional plate ribs or bidirectional plates and are only arranged at the tension part of the external wall span, and in special cases, the external wall rib plates are not arranged.
Preferably, the direction of the external wall rib plate can be horizontal or vertical.
Preferably, the thickness of the outer wall flat plate is equal to that of the outer wall rib plate as much as possible.
The utility model discloses according to atress size adjustment wall thickness, the utility model discloses utensil beneficial effect: in the indoor positive bending moment place, the ribbed slab is adopted, so that the consumption of concrete in a tension area can be reduced; the local thickened cross section is adopted at the position of the hogging moment of the support, which is beneficial to increasing the rigidity and reducing the reinforcing bars; thickness based on the prerequisite adjustment outer wall of component atress, the utility model discloses a material quantity will be less than traditional basement outer wall, and structural rigidity is greater than traditional basement outer wall.
The utility model relates to a novel basement exterior wall structure, specially adapted multilayer basement also can be used to the reinforcement transformation of basement exterior wall structure.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 3, the utility model relates to a basement outer wall, include: the wall comprises an outer wall flat plate 1, an outer wall rib plate 2, a wall or column 3, a floor slab 4 and a bottom plate 5. The outer wall flat plate 1 and the outer wall rib plate 2 are arranged between the floor slab 4 and the bottom plate 5 or between the floor slab 4 and the floor slab 4, and the outer wall rib plate 2 is arranged in the middle of each layer of outer wall.
Referring to fig. 4, the exterior wall floor 2 may preferably be a vertical unidirectional floor.
Referring to fig. 6, the exterior wall rib 2 may preferably be a bidirectional rib.
Referring to fig. 8, the exterior wall floor 2 may preferably be a horizontal floor.
The utility model discloses a construction is with traditional basement outer wall, also is earlier ligature reinforcing bar, then concreting. The difference lies in the utility model discloses an outer wall inboard is not same thickness.
