Description

A kind of concrete hollow board

(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 concrete hollow board, and it is fast that this concrete hollow board 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 steel reinforcement concrete hollow plate " 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 concrete hollow board 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 concrete hollow board.And when being applied in than the large spatial structure concrete hollow board, 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 space structures reinforced concrete hollow slab combination rib steel reinforcement concrete hollow plate " patent of invention, its disclosed concrete hollow board 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 internal-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 internal-rib die cavity are arranged on the structure base plate, when concrete hollow board is applied to the concrete hollow plated construction, on the structure base plate, just can form cast-in-situ concrete 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 further improved the overall performance of concrete hollow board, anti-seismic performance, reduce the thickness of concrete hollow board, alleviated dead load, reduced cost.But this concrete hollow board is in carrying, work progress, and its structure base plate is prone to the phenomenon that fractures, thereby the breakage rate of concrete hollow board is big, and carrying, construction inconvenience have increased construction cost.Simultaneously, after this concrete hollow board is applied to the hollow steel bar concrete hollow board, because formed Cast-in-place concrete rib is the rib of rectangle, its stress performance is not quite reasonable, often need increase the sectional dimension of rib, increase reinforcing bar and concrete consumption, increase the cost of concrete hollow board, therefore, 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 that mechanical property is good, characteristics such as easy construction, construction cost are low.

Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, hollow unit, hollow unit is wrapped up in and is contained in the steel bar concrete, hollow unit alternately, be the cast-in-situ reinforced concrete rib each other, hollow unit comprises hollow mould shell and base plate, hollow mould shell and base plate connect into integral body, at least 2 hollow mould shells are arranged alternately on the base plate, alternate cavity between the hollow mould shell and base plate constitute cast-in-place structural internal-rib die cavity, cast-in-situ reinforced concrete forms the cast-in-situ reinforced concrete internal-rib in cast-in-place structural internal-rib die cavity, and link to each other with the cast-in-situ reinforced concrete rib, it is characterized in that being provided with in the cast-in-place structural internal-rib die cavity between the described adjacent cavities formwork at least one support draw piece, the adjacent cavities formwork is connected to each other, there is interior puncture groove the hollow mould shell of cast-in-place structural internal-rib die cavity and the contact site of base plate, and corresponding cast-in-situ reinforced concrete internal-rib is the inverted T shape internal-rib.Like this, owing in the inferior rib die cavity of adjacent cavities formwork, be provided with the support draw piece, adjacent formwork is connected to each other, hollow mould shell in the concrete hollow board involves each other by the support draw piece, thereby the intensity of concrete hollow board and rigidity are bigger, shock resistance is better, and its structure base plate is frangibility more not, and is more convenient when carrying and construction; Simultaneously, because puncture groove in hollow mould shell and base plate contact site are set to, when concrete hollow board is constructed, the Cast-in-place concrete rib has formed the inverted T-shaped rib, its shape of cross section has become inverted T-shaped by rectangle, thereby the mechanical property of hollowcore slab is improved greatly, can reduce the sectional dimension of Cast-in-place concrete rib, reduce reinforcing bar and concrete consumption, reduce the concrete hollow board cost, thereby concrete hollow board to have mechanical property good, easy construction, characteristics such as construction cost is low, thereby problems of the prior art have been solved preferably, reach purpose of the present invention, be applicable to the hollowcore slab of various cast-in-situ reinforced concretes or prestressed reinforced concrete, superstructure, roof system, sole plate, body of wall or hollow bridges are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention is that also there is interior puncture groove at least one other side of described hollow mould shell and the contact site of base plate, and the cast-in-situ reinforced concrete rib of corresponding site is the inverted T shape rib.Like this, in the puncture groove, can form the I-shaped rib structure in concrete pours into, improve the mechanical property of cast-in-situ concrete structure, simultaneously, can with the complete build-in of hollow mould shell in Cast-in-place concrete, can significantly reduce the probability that produces the crack between Cast-in-place concrete and the precast reinforced concrete hollow board.
