Description
Technical field
The utility model is a kind of cap node for basement flat slab structure, belongs to the innovative technology of arch without beam cap node.
Background technology
Arch without beam in invention in 1910, belongs to a kind of slab column system of bidirectional stress by Switzerland designer.Compare conventional beam-and-slab floor, arch without beam not only has upper flat, is convenient to the feature of space flexible isolation, and can reduce structural element height, under the prerequisite ensureing same structure clear height, effectively reduces floor height.For underground garage, floor height reduces and means reducing of vertical member length, the reduction of the reduction of earthwork evacuation two, base plate or sidewall head height, as can be seen here, rationally effectively reduce floor height and obviously can reduce construction cost, therefore in basement parking garage structure, arch without beam application widely.
But, the structural performance of more conventional beam and slab structure, arch without beam ductility is poor, destroy and belong to fragility punching failure more, so how to design cap node, make flat slab structure not only retain original advantage but also improve structural safety, become the matter of utmost importance that structural engineer needs to solve.
Summary of the invention
The purpose of this utility model is consider the problems referred to above and provide a kind of cap node for basement flat slab structure.The utility model when on building using function without when affect, improve the supporting capacity of cap greatly, effectively strengthen the connection of cap district floor and post, the effect of the cap district of performance preferably sheet-pile framework, to make every effort to node construction simple simultaneously.Way directly, reliably.
The technical solution of the utility model is: the cap node for basement flat slab structure of the present utility model, include cap, muscle at the bottom of muscle, plate face, cap district indulged in cap district shearing resistance stirrup, plate face, cap district, support the frame column of cap, wherein cap is bearing on frame column, cap district indulges in plate face muscle at the bottom of muscle and plate face, cap district and is arranged in cap, and plate face, cap district is indulged at the bottom of the Ban Ding and plate that at the bottom of muscle and plate face, cap district, muscle lays respectively at cap pairwise orthogonal direction, shearing resistance stirrup in cap district connects plate face, cap district and indulges muscle formation reinforcing cage.
The utility model compared with the prior art, there is following beneficial effect: the cap node for basement flat slab structure of the present utility model is under the prerequisite substantially not affecting building using function, retain the advantage adopting arch without beam, the connection of effective reinforcement cap district's floor and cap, improve the supporting capacity of cap greatly, play the effect of cap district sheet-pile framework preferably.The cap shearing resistance stirrup arranged not only plays shearing resistance, the punch resistant capability of cap, and to the orthogonal stripes concrete Constrained effect of cap district, can improve concrete supporting capacity, improve again concrete ductility.

Detailed description of the invention
Embodiment:
Structural representation of the present utility model is as Fig. 1, shown in 2, cap node for basement flat slab structure of the present utility model, include cap 1, cap district shearing resistance stirrup 2, cap district indulges muscle 3 in plate face, muscle 4 at the bottom of plate face, cap district, support the frame column 8 of cap, wherein cap 1 is bearing on frame column 8, cap district indulges muscle 3 in plate face, at the bottom of plate face, cap district, muscle 4 is arranged in cap 1, and plate face, cap district is indulged at the bottom of the Ban Ding and plate that at the bottom of muscle 3 and plate face, cap district, muscle 4 lays respectively at cap 1 pairwise orthogonal direction, cap district shearing resistance stirrup 2 connects plate face, cap district to be indulged muscle 3 and forms reinforcing cage.
In the present embodiment, muscle 4 at the bottom of plate face, above-mentioned cap district includes the elongated vertical muscle 5 in floor plate face and floor plate face, cap district adds muscle 6, the elongated vertical muscle 5 in floor plate face and floor plate face, cap district add muscle 6 two kinds of reinforcing bars and place at scope interval, cap district, and cap district shearing resistance stirrup 2 connects the elongated vertical muscle 5 in floor plate face and floor plate face, cap district to be added muscle 6 and form reinforcing cage.
In the present embodiment, the bottom of above-mentioned cap 1 is also provided with cap district diagonal bar 10.
In the present embodiment, the bottom of above-mentioned cap 1 is provided with the cap district diagonal bar 10 of 45 jiaos and 135 jiaos both directions, and the cap district diagonal bar 10 of both direction is connected and fixed by horizontal hoop 9.
In the present embodiment, above-mentioned cap district diagonal bar 10 is reinforcing bar.
Application example of the present utility model is as follows: certain residential structure is positioned at Guangzhou City, and be high-rise and Super high-rise dwelling house high building on the ground in place, underground is 3 ~ 4 layers of basement of full paving.This project basement area is comparatively large, and basement standard span is 8m*8m.
Contrast with the superstructure pattern of routine, such as nine-squares beam, rood beam, Zi Liang, order word beam, the large plate of haunch (large plate) etc., basement parking garage position adopt arch without beam, standard across concrete and reinforcing bar comprehensive cost economize most, be secondly order word beam superstructure.Arch without beam differs within 5% with order word beam superstructure cost.Basement roof position adopt arch without beam, standard across concrete and reinforcing bar comprehensive cost economize most, other scheme costs are at least high by more than 10%.
Therefore, choose the cost that arch without beam scheme contributes to reducing superstructure, and this pattern also brings other economic benefit: one is reduce basement floor height at least more than 200mm; Two is reduce excavation of foundation pit amount, reduces pattern foundation pit supporting structure expense; Three is for high water level area, and floor height reduces and after base plate lifting, base plate head reduces, and exterior wall Water And Earth Pressures reduces, the stressed reduction of base plate and exterior wall, the corresponding minimizing of steel using amount; Four is that after base plate head reduces, the stressed reduction of anti-float anchor rod, rock-bolt length also can correspondingly reduce.
In a word, the overall economic efficiency that arch without beam pattern produces is considerable, and basement position adopts arch without beam to become first-selected.Therefore, the bearing capacity effectively improving arch without beam just seems particularly important.
Adopt this practicality example, effectively can strengthen the connection of cap district floor and post, improve the supporting capacity of cap greatly, play the effect of cap district sheet-pile framework preferably.The vertical shearing resistance stirrup arranged not only plays shearing resistance, the punch resistant capability of cap, and to the orthogonal stripes concrete Constrained effect of cap district, can improve concrete supporting capacity, improve again concrete ductility.
