Abstract
A hollow reinforced concrete comprises concrete cast in site, hollow components as fillers spaced each other and contained in the former, and some ribs are cast in site between the said fillers. The hollow component consists of a concrete substrate and fillers on the said substrate. The said fillers are arranged on the substrate in parallel and connected with the substrate into a whole body. Between the fillers, some internal mould cavities, in parallel or perpendicular, are formed with at least one support in each of them. The support is in a shape of a truss. The concrete can be used as hollow roof, basement, wall and hollow bridge beam.
Description
(1) technical field
The present invention relates to a kind of concrete hollow board.
(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.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 in the concrete hollow board is in carrying, work progress, and its structure base plate is prone to the phenomenon that fractures, and breakage rate is big, and carrying, construction inconvenience have increased construction cost.For this reason, develop a kind of novel concrete hollow board for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete hollow board, have characteristics such as easy construction, cost is low, mechanical property is good.
Solution of the present invention is on the basis of existing technology, comprise cast-in-situ reinforced concrete, cavity structural member for filling, cavity structural member for filling each other alternately, and wrap up in and be contained in the cast-in-situ reinforced concrete, cavity structural member for filling is the Cast-in-place concrete rib each other, cavity structural member for filling comprises the concrete base plate, obturator on the concrete base plate, obturator is alternately on the concrete base plate, and be linked to be whole primary structure member with it, the parallel or quadrature of alternate internal-rib die cavity between obturator has cast-in-situ reinforced concrete to form the Cast-in-place concrete internal-rib, and links to each other with the Cast-in-place concrete rib in the internal-rib die cavity, it is characterized in that in the described internal-rib die cavity support draw piece being arranged, the support draw piece is a truss-like support draw piece.Like this, owing in the internal-rib die cavity support draw piece is arranged, the support draw piece is a truss-like support draw piece, thereby the intensity of cavity structural member for filling and rigidity are bigger, shock resistance is better, can further improve the overall performance of Cavity structural member, anti-seismic performance and mechanical property, has the intensity height, rigidity is big, frangibility not, carrying, easy construction, characteristics such as cost is low, simultaneously, can participate in the structure stress of concrete hollow board, improve the mechanical property of hollowcore slab, therefore, this concrete hollow board has easy construction, cost is low, characteristics such as mechanical property is good, thus reached purpose of the present invention, be applicable to the hollow building cover of cast-in-situ reinforced concrete or prestressed reinforced concrete, roof system, sole plate, body of wall and hollow bridges are used, and are specially adapted to hollow arch without beam and use.
