Description
Technical field
The utility model relates to a kind of concrete brick folding foded plate foundation, is applicable to civil engineering groundwork basic field.
Background technology
Foded plate foundation is a kind of novel foundation, and foded plate foundation can be converted into axle power a large amount of moments of flexure of flat board, shearing.But thin meeting crossed by flap makes soil rigidity too low thus relative settlement is comparatively large, the blocked up meeting of flap causes uneconomical.In addition, foded plate foundation bearing capacity is too low is also the importance limiting its application.
Utility model content
The technical problem that the utility model solves is to provide a kind of for concrete brick folding foded plate foundation, and this base thickness is comparatively large and manufacturing cost is relatively low.
For this reason, the concrete brick folding foded plate foundation that the utility model provides, foded plate foundation upper strata be armored concrete plate, middle for brickwork, lower floor be precast concrete plank, the adjacent flap of foded plate foundation hands over spine position to arrange grade beam, grade beam and shaping with cast in place concrete plate formed by integrally casting.The centre of level board arranges reinforcing bar load body, be positioned at the reinforcing bar load body at foded plate foundation two ends as electric osmose pole, reduced the water content of shallow soil by electric osmose, make shallow-layer form crust layer and participate in carrying, upper part load is passed to hardpan below by reinforcing bar load body.
The concrete brick folding foded plate foundation that the utility model provides makes flap thickness increase by arranging brickwork in centre, and then effectively strengthens soil rigidity, because thickness increasing portion is the lower brickwork of material cost, therefore, it is possible to be dirt cheap.Of the present utility modelly be carried through two kinds of modes and realize, carried by shallow-layer crust layer on the one hand, the hardpan reached below by reinforcing bar load body is on the other hand carried, so bearing capacity is relatively high, mechanical property will exceed much than traditional basis.

In each accompanying drawing: 1, precast concrete plank, 2, brickwork, 3, cast in place concrete plate, 4, grade beam, 5, reinforcing bar load body, 6, sand-gravel cushion.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, the concrete brick folding foded plate foundation that the utility model provides, comprise precast concrete plank 1, brickwork 2, cast in place concrete plate 3, grade beam 4, reinforcing bar load body 5, sand-gravel cushion 6, concrete brick folding foded plate foundation bottom is precast concrete plank 1, precast concrete plank 1 thickness is 12 ~ 18cm, in foded plate foundation, the angle of horizontal segment and oblique section is 20 ~ 35 degree, the horizontal projection length of oblique section of foded plate foundation is identical with horizontal section length, precast concrete plank 1 arranges brickwork 2 above, brickwork 2 thickness is determined according to stock mould number, can be 12cm, 24cm, 29cm, 36cm, 48cm, brickwork 2 building method adopts one along a fourth or three along a fourth.Brickwork 2 arranges cast in place concrete plate 3 above, and cast in place concrete plate 3 thickness is 12 ~ 15cm.Adjacent flap hands over spine position to arrange grade beam 4, and grade beam 4 width is greater than wall thickness, adopts 30cm, plays the effect of distribution loading and the brick house of reinforcement.Grade beam 4 should look the length of building and the uniformity of ground, and grade beam 4 height adopts 60 ~ 90cm.Grade beam 4 is shaping with cast in place concrete plate 3 formed by integrally casting.Concrete brick folding foded plate foundation horizontal segment precast concrete plank 1 arranges reinforcing bar load body 5 below, in order to play the carrying effect of the reinforcing bar load body 5 periphery soil body, prevent reinforcing bar load body 5 stress from concentrating, between foded plate foundation horizontal segment precast concrete plank 1 and reinforcing bar load body 5, sand-gravel cushion 6 is set, sand-gravel cushion 6 thickness adopts 20cm, and material adopts particle diameter to be less than the rubble encryption coarse sand compacting of 3cm.Reinforcing bar load body 5 forms to six roots of sensation reinforcement welding by three, and first joint reinforcing bar load body 5 makes tip, and every root reinforcing bar load body 5 enters hardpan.Reinforcing bar load body 5 is placed in soil layer, and soil plays lateral-supporting effect to the lateral pressure of reinforcing bar load body 5, maintains the stability of reinforcing bar load body 5.Reinforcing bar load body 5 sectional area is determined according to reinforcing bar load body length and bearing stratum soil property situation, is erratic boulder or block stone for bearing stratum soil property, and when namely grogs footpath is greater than 200mm, reinforcing bar load body 5 sectional area adopts 130 ~ 150mm; Be cobble or rubble for bearing stratum soil property, when namely grogs footpath is greater than 60mm and is less than or equal to during 200mm, reinforcing bar load body 5 sectional area adopts 130 ~ 120mm; For bearing stratum soil property be gravel soil, when namely grogs footpath is greater than 5mm and is less than or equal to during 60mm, reinforcing bar load body 5 sectional area adopt 110 ~ 120mm; For bearing stratum soil property be gravel soil, when namely grogs footpath is greater than 5mm and is less than or equal to during 60mm, reinforcing bar load body 5 sectional area adopt 90 ~ 110mm; Be sand for bearing stratum soil property, when namely grogs footpath is greater than 0.075mm and is less than or equal to during 2mm, reinforcing bar load body 5 sectional area adopts 70 ~ 90mm; Be clay for bearing stratum soil property, when namely grogs footpath is less than or equal to during 0.075mm, reinforcing bar load body 5 sectional area adopts 50 ~ 70mm.Above data are experimental datas when being 10m according to reinforcing bar load body 5 length, when reinforcing bar load body 5 length is greater than 10m, reinforcing bar load body 5 sectional area will expand, sampling factor is 1.05 ~ 1.2, when reinforcing bar load body 5 length is less than 10m, reinforcing bar load body 5 sectional area will reduce, and coefficient of reduction is 0.8 ~ 0.95.In foded plate foundation, the reinforcing bar load body 5 of left hand edge and right hand edge is as electric osmose pole.
Electric osmose pole adopts reinforcing bar load body 5, reduces electric osmose cost.Electroosmosis dewatering not only can reduce water content, can also improve reinforcing bar load body 5 side friction.In addition, the effect of the utility model electroosmosis dewatering is effectively to improve reinforcing bar load body 5 and the coefficient effect of soil, this is because superficial part soil passes through electroosmosis dewatering, form crust layer, crust layer has increased significantly than original ratio of rigidity with the ratio of rigidity of reinforcing bar load body 5, is conducive to stake soil compatible deformation.
