Abstract
A hollow component for hollow plate consists of several open hollow mould shells and a substrate. At least two shells are arranged on the substrate and spaced each other to form internal rib cavities for casting in site. Some supporting parts are arranged in the internal rib cavities, so that the hollow component has higher strength and better shockproof performance. It has simple structure, costs low, is manufactured efficiently, and can be used for hollow plate of reinforced concrete cast in site or pre-fabricated reinforced concrete for hollow plate, hollow roof, basement, wall and hollow bridge beam, especially for hollow beamless roof.
Description
(1) technical field
The present invention relates to a kind of hollowcore slab Cavity structural member.
(2) background technology
Advantages such as at present, at present, the most precast hollow slab that adopts of the building of brick mix structure and reinforced concrete structure is 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.And when being applied in than the large spatial structure superstructure, its stress performance is also phase strain differential thereupon, do not have time rib between the cast-in-place main rib and connect, thereby make the size of main rib need the phase strain big, or the quantity of main rib increases, and causes material usage to increase, and cost increases.For this reason, the applicant has applied for that November 15 calendar year 2001 publication number is that CN1349028A, name are called " a kind of Comobined ribbed cavity member for spatial structure roof " patent of invention, its disclosed Cavity structural member includes 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 (internal-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, reduced the thickness of superstructure, alleviate dead load, reduced cost.But this Cavity structural member is in carrying, work progress, its structure base plate is prone to the phenomenon that fractures, thereby the breakage rate of Cavity structural member is big, carrying, construction inconvenience have increased construction cost, simultaneously, it manufactures trouble, cost is higher, therefore, develops a kind of novel hollowcore slab and has been urgent need with Cavity structural member.
