Abstract

The present invention relates to a cavity member for a hollow plate, which comprises a cavity shuttering (1) and a base plate (2), wherein the cavity shuttering (1) and the base plate (2) are connected into a whole. At least two cavity shutterings are alternately arranged on the base plate. The side surface of each cavity shuttering and the base plate (2) form at least one inner rib mould cavity (3) with a structure, and other side surfaces of the cavity shuttering (1) form an outer fin with a cast-in-situ structure or a side mould plate of a beam or a wall. The present invention is characterized in that the cavity shuttering (1) is a cavity shuttering with a corrugated wall. In this way, due to the fact that the cavity shuttering of the cavity member is the cavity shuttering with the corrugated wall, after the cavity member is applied to cast-in-situ hollow floors, the contact surface of the cavity shuttering and the cast-in-situ concrete are increased, and therefore, the cavity shuttering and the cast-in-situ concrete can be embedded and fixed more firmly, and the separation phenomenon is not easy to happen. Simultaneously, the cavity member also has the characteristics of easy manufacture, low cost, etc. The present invention is suitable for various hollow floors, roofs, foundation slabs, walls or hollow bridges which are respectively made of cast-in-situ reinforcement concrete or prestressed reinforcement concrete, and is especially suitable for hollow beamless floors.

Description

A kind of hollowcore slab Cavity structural member

(1) technical field

The present invention relates to a kind of hollowcore slab 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 are arranged on the structure base plate, when Cavity structural member is applied to building cover structure, 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 overall performance, the anti-seismic performance of superstructure have further been improved, reduce the thickness of superstructure, alleviated dead load, reduced cost.But, after this Cavity structural member is applied to hollow building cover, the mutual build-in of its hollow mould shell and Cast-in-place concrete, often because of the after-contraction of Cast-in-place concrete setting and harden, and the phenomenon that occurs coming to nothing, thereby, build-in each other is not firm, and the globality of main is Cavity structural member is bad, easily shelling in transportation, installation, work progress, discrete, therefore, develop a kind of novel hollowcore slab and be urgent need with Cavity structural member.

(3) summary of the invention

The object of the present invention is to provide a kind of hollowcore slab Cavity structural member, have good integrity, in transportation, installation, work progress, be difficult for shelling, characteristics such as discrete.

Solution of the present invention is on the basis of existing technology, include hollow mould shell, base plate, hollow mould shell and base plate connect into integral body, at least two hollow mould shells are arranged alternately on the base plate, the side of hollow mould shell 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, hollow mould shell is the hollow mould shell of bellows wall, and the bellows wall that it is characterized in that described bellows wall hollow mould shell is anchored in the surface of base plate or is clipped in the bottom-plate body.Like this, because the hollow mould shell of Cavity structural member is the hollow mould shell of bellows wall, after being applied to cast-in-situ concrete hollow floor, its hollow mould shell and Cast-in-place concrete contact surface increase, and build-in is firm each other, is not prone to the phenomenon of coming to nothing, simultaneously, because the bellows wall of bellows wall hollow mould shell is anchored in the surface of base plate or is clipped in the bottom-plate body, thereby has improved the globality of Cavity structural member greatly, effectively ensured Cavity structural member unlikely shelling in transportation, installation, work progress, discrete; In addition, Cavity structural member also has makes characteristics such as easy, that cost is low, thereby reaches purpose of the present invention.The hollow building cover, roof system, sole plate, body of wall or the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention is that also described bellows wall hollow mould shell is wavy metal wall hollow mould shell or plastic ripple wall hollow mould shell.Like this, the kind of bellows wall hollow mould shell is many, makes things convenient for design and construction unit to select for use; Simultaneously, wavy metal wall hollow mould shell or plastic ripple wall hollow mould shell are made easily, and corresponding cost is low.
