Description

A kind of Cavity structural member

The application is that June 24, application number in 2003 are that 03146761.X, name are called the dividing an application of application for a patent for invention of " a kind of Cavity structural member " for the applying date.

(1) technical field

The present invention relates to a kind of Cavity structural member.

(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 is arranged on the structure base plate, on the structure base plate, just can form the inferior rib of cast-in-place structure, fellowship structure base plate, main rib, upper plate stressed, form two-way main rib time rib force structure, not only solve problems of the prior art, but also further improved overall performance, the anti-seismic performance of superstructure, reduced the thickness of superstructure, alleviate dead load, reduced cost.But this Cavity structural member is in carrying, construction and long-term use, and 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, use the back if crack, then influence the presentation quality of superstructure ceiling.For this reason, develop a kind of novel Cavity structural member for being badly in need of.

(3) summary of the invention

The object of the present invention is to provide a kind of Cavity structural member, have characteristics such as intensity height, non-frangibility, carrying, easy construction.

Solution of the present invention is on the basis of existing technology, include hollow mould shell and base plate, hollow mould shell and base plate connect into integral body, have 2 hollow mould shells on the base plate at least alternately, the side that is oppositely arranged of the adjacent cavities formwork on its base plate and base plate constitute at least one cast-in-place structural internal-rib die cavity, other lateral surface of hollow mould shell constitutes the side template of cast-in-place structural external fin or beam or wall, it is characterized in that accompanying in the base plate at least one presstressed reinforcing steel, presstressed reinforcing steel exposes from the base plate termination, is provided with at least more than one support draw piece in the internal-rib die cavity.Like this, improve the overall performance of Cavity structural member greatly, reduced the breakage rate in the handling process.Owing to accompany at least one presstressed reinforcing steel in base plate, thereby the intensity of Cavity structural member and rigidity are bigger, and shock resistance is better, its structure base plate is frangibility more not, carrying is more convenient with construction, simultaneously, uses back superstructure crack resistance good, be difficult for cracking, can not influence the presentation quality of superstructure ceiling, simultaneously, because presstressed reinforcing steel exposes from the base plate termination, help improving the globality of superstructure, thereby reach purpose of the present invention; In addition, Cavity structural member also has characteristics such as simple in structure, easily manufactured, that cost is low, is applicable to that hollow building cover, roof system, sole plate, body of wall and the hollow bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete used, and is specially adapted to hollow arch without beam and uses.

Feature of the present invention is that also described presstressed reinforcing steel exposes from strip base plate two ends.

Feature of the present invention is that also described presstressed reinforcing steel is prestressed reinforcement or steel strand.Like this, accompany prestressed reinforcement or steel strand in the base plate, made things convenient for design and construction unit to select for use, improved the impact strength and the rupture strength of Cavity structural member greatly.
