Description

A kind of Cavity structural member

The application for the applying date be that June 2, application number in 2003 are 03137269.4, name is called the dividing an application of application for a patent for invention of " a kind of Cavity structural member ".

(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 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.After but this Cavity structural member is applied to hollow building cover, because the wall and the structure base plate of hollow mould shell are easily damaged in carrying and work progress, particularly be subjected to the strike or the collision of various weights and junk, because of insufficient strength, shock resistance is poor, damaged hole often occurs, the destruction that causes Cavity structural member, make troubles to construction, increase cost, and the duration is affected, therefore, 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 excellent in cushion effect, characteristics such as cracky, easy construction, cost be not low.

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, its side 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 internal-rib the side or/and other lateral surface and base plate intersect vertically.Like this, owing in Cavity structural member, accompany thin band, the ability of its shock resistance and collision is big, the intensity height, good toughness, thin band of Unit Weight and cementitious matter bonding surface are big, and corresponding bond stress is big, when Cavity structural member is impacted or collide, Cavity structural member is not prone to damaged hole, even the destruction crackle is arranged, because the effect that involves of thin band does not need to repair yet, do not influence follow-up construction, thereby easy construction, cost is low, simultaneously, the wall that also can corresponding attenuate formwork and the thickness of base plate, economical with materials, weight reduction, thereby it is more convenient to construct, cost is lower, by the binding of reinforce, improved the overall performance of Cavity structural member greatly, thereby reached purpose of the present invention; In addition, that Cavity structural member also has is simple in structure, make characteristics such as easy, is applicable to that hollow building cover, roof system, sole plate, body of wall or the hollow bridges of various cast-in-situ reinforced concretes or prestressed reinforced concrete used, and is specially adapted to hollow arch without beam and uses.

Feature of the present invention is that also the internal-rib side in the described same internal-rib die cavity all intersects vertically with base plate.
