Abstract
A combined-rib cavity member for space-structure flooring includes cavity form and structure bottom plate, which are connected into one integral whole. It is characterized by that there are at least two cavity forms arranged alternate with each other on the structure bottom plate, its side forms with the structure bottle plate at least one subrit form cavity of casti-in-situ structure, and other other sides of the cavity form forms the side fromboard of main rib or beam or wall for cast-in-situ structure. By this, the subrib of cast-in-situ structure can be formed in the sub-rib form cavity on the structure battom plate, the sub-rib participates in load bearing of structural bottom slat, cast-in-situ main rib, cast-in-sita upper slab so to a load-bearing space structure, improved mechanical property, raise integrity and anti-shock property, decrease structural wt. lower cost and make construction be convenient.
Description
(1) technical field
The present invention relates to a kind of Comobined ribbed cavity member for spatial structure roof.
(2) background technology
Advantages such as at present, the building of brick mix structure and reinforced concrete structure major part adopts precast hollow slab as floor structure, and it is fast that this floor structure has speed of application, and cost is low.But, only use the cement mortar joint filling, thereby globality is poor, is unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur owing to firmly do not link between adjacent two precast hollow slabs.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (solid, hollow), though solved antidetonation and problems of crack, will use template in a large number during construction, have not only increased expense, and have slowed down speed of application, have prolonged the duration.Application number is " a kind of combination concrete rib floor structure " utility model patent of 00203695.9, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is placed at interval, on prefabricated plate, be fixed with formwork, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connects as one with dark rib.Though this floor structure can be saved a large amount of templates, accelerate construction progress, but because formwork is what to separate with prefabricated plate, its strength and stiffness are corresponding relatively poor, thereby the problem that exists formwork easily to break, simultaneously, formwork is fixed on and does not relate to concrete fixed form on the prefabricated plate, thereby fixed in place is difficult.And the patent No. is 93206310.1 shuttering member utility model patent, it constitutes hollow mould shell by sidewall and formwork upper plate and is connected to form totally-enclosed cavity polyhedral structure with lower shoe again, prefabricated ribs is arranged in it, during use member is placed on the supporter of floor gap, formation bonded to one another is whole between cast-in-place main rib, the shuttering member.When this kind member uses, be a kind of prefabricated noggin piece purely, the ribs in the die housing only is used to support formwork, can not participate in the whole stressed of superstructure.Tensile region particularly, its go to the bottom and ribs by actual tensional element design.When normal the use, if stress deformation, then member easily comes off, and forms interface between Cast-in-place concrete and prefabricated formwork, and cracks, and is when particularly span is big, all the more so.Simultaneously, alternation load action, vibrating load effect, seismic loading and deflection deformation when it can not bear normal the use, and on the formwork suspender member can not be installed.At present, the practical engineering application of this member has proved and has had Interface Crack between this formwork and the steel bar concrete main rib and potential safety hazard such as may come off.And when being applied in, not having time rib between the cast-in-place main rib and connect, thereby make the size of main rib need the phase strain big than the large spatial structure superstructure, or the increase of the quantity of main rib, cause material usage to increase, cost increases.Therefore developing a kind of novel prefabricated cavity component in use for cover of storied building in space structure replaces existing formwork for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of prefabricated cavity component in use for cover of storied building in space structure, after being applied to superstructure, the stress performance of superstructure is improved, the thickness of corresponding minimizing superstructure, reduce cost, also have simple in structure, characteristics such as intensity is high, convenient construction and transport simultaneously.
Solution of the present invention is to include formwork and structure base plate, hollow mould shell and structure base plate connect into integral body, it is characterized in that having 2 hollow mould shells on the structure base plate at least alternately, its side and structure base plate constitute at least one cast-in-place structural time rib die cavity, and other lateral surface of hollow mould shell constitutes the side template of cast-in-place structural main rib or beam or wall.Like this, because on the prior art basis, at least 2 hollow mould shells and at least 1 cast-in-place structural time rib die cavity are arranged on the structure base plate, on the structure base plate, just can form cast-in-place structure time rib, fellowship structure base plate, main rib, upper plate stressed, form two-way main rib time rib force structure, problems of the prior art have not only been solved, but also overall performance, the anti-seismic performance of superstructure have further been improved, reduce the thickness of superstructure, alleviated dead load, reduced cost, also have characteristics such as intensity height, simple in structure, construction, convenient transportation simultaneously.
