Abstract
The utility model relates to a ribbed folded-plate waterproof bottom plate which comprises multiple lower horizontal plates and multiple upper horizontal plates, wherein the lower horizontal plates and the upper horizontal plates are alternately arranged; each lower horizontal plate is connected with an adjacent upper horizontal plate through a vertical plate; and height difference is formed between the lower horizontal plates and the upper horizontal plates. In the utility model, by adopting a vertical plate part as a web of an anti-bending component, the bending resistance of the waterproof bottom plate is improved, the flexural bearing capacity of the waterproof bottom plate is enhanced, and the cracks are reduced; and due to relatively small calculated span and relatively small calculated bending moment of the horizontal part, a relatively thin waterproof bottom plate is arranged at the horizontal part, the rebar and concrete are saved on the premise of meeting the stress requirement, and the construction is relatively convenient.
Description
Technical field
The utility model relates to a kind of building structure, and particularly a kind of close rib flap resists water-bed plate.
Background technology
Basement is the room that is in the building below the outdoor ground.Below housing bottom, build basement, can improve building land efficient.Some Tall Building Foundation buried depths are very big, make full use of this degree of depth and build basement, and its economic effect and result of use are all good.When groundwater table was descended room floor above Ground, the base plate of basement not only bore the vertical load that acts on above it, also bore phreatic buoyancy, therefore must have the ability of enough intensity, rigidity, impermeabilisation ability and anti-floating power.
Basement is in the time spent of doing that runs into high water head, and basement bottom board is generally made anti-water-bed plate, is divided into beam and slab type and flat.Under high hydraulic action, anti-water-bed plate general thickness is bigger, and it is more to calculate arrangement of reinforcement, when span is very big, also wants the design basis beam to cut apart the anti-water plate of bulk.Because traditional anti-water plate thickness of slab is bigger, arrangement of reinforcement is more closeer, is difficult for construction during construction, and causes the steel reinforcement and concrete material waste.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency and provide a kind of close rib flap to resist water-bed plate, and the anti-water-bed plate of this kind can make full use of the space-load system of thin plate, stressed evenly, reduce concrete and amount of reinforcement.
The technical scheme that the utility model is taked is:
A kind of close rib flap resists water-bed plate, comprises a plurality of lower horizontal boards and a plurality of level board of going up, and lower horizontal board and last level board are alternately arranged, and is connected lower horizontal board and last level board formation difference in height through vertical plate between lower horizontal board and adjacent last level board.
Described vertical plate respectively with lower horizontal board, go up that level board is vertical to be connected.The rectangular waveform in the anti-water-bed plate longitudinal section of described close rib flap.The anti-water-bed plate of close rib flap is through casting or be welded into an integral body.
The utility model utilizes the web of vertical plate part as bending resistance component, improves the anti-bending strength of anti-water-bed plate, improves the anti-bending bearing capacity of anti-water-bed plate, reduces the generation in crack; Horizontal component is done thin anti-water-bed plate because effective span is less, and calculated bending moment is less, can satisfy saving reinforcing bar and concrete under the prerequisite of force request, and it is comparatively convenient to construct.Make full use of the space performance of flap; Equivalence becomes corresponding i-shaped roof beam cross section; Last level board can be used as the top flange in equivalent i-shaped roof beam cross section, and lower horizontal board can be used as the bottom flange in equivalent i-shaped roof beam cross section, and vertical plate can be used as the web in equivalent i-shaped roof beam cross section.
The utility model will be striden anti-water-bed plate greatly and calculated according to unidirectional close rib flap, and the angle between adjacent flap is 90 °, can realize mutual support, to reduce effective span.Vertical plate has improved the required interior arm of force height of reinforcing bar of bending resistance, and the soil of backfill can be used as the calculated height that counterweight reduces head in the groove of formation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1. go up level board, 2. lower horizontal board, 3. vertical plate.
The specific embodiment
Further specify the present invention below in conjunction with the accompanying drawing and the specific embodiment.
As shown in Figure 1; A kind of close rib flap resists water-bed plate, comprises a plurality of lower horizontal boards 2 and a plurality of level boards 1 of going up, and lower horizontal board 2 is alternately arranged with last level board 1; 1 of lower horizontal board 2 and adjacent last level board are connected through vertical plate 3, and lower horizontal board 2 forms difference in height with last level board 1.
When design, calculate, or adopt finite element SPATIAL CALCULATION method to analyze according to equivalent i beam.During construction, the reinforcing bar of close rib flap will be constructed and put in place, and assurance level board and vertical plate support each other and provide support.The soil of backfill can be used as the calculated height that counterweight reduces head in the groove.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
Claims (2)
1. a close rib flap resists water-bed plate; It is characterized in that it comprises a plurality of lower horizontal boards and a plurality of level board of going up, lower horizontal board and last level board are alternately arranged; Be connected through vertical plate between lower horizontal board and adjacent last level board, lower horizontal board and last level board form difference in height.
2. close rib flap according to claim 1 resists water-bed plate, it is characterized in that, the rectangular waveform in its longitudinal section, vertical plate respectively with lower horizontal board, go up that level board is vertical to be connected.
