Description
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(2) background technology
At present, Cast-in-place Concrete Building Floor is to use wider floor structural form, and the lightening permanent loose tool of filling in it has various hollow sections and box, and box has hollow or solid.Is that ZL00203695.9, name are called " combination concrete hidden rib floor structure " utility model patent as Shijiazhuang City, Hebei Province city beam army in the patent No. of application on February 23rd, 2000, a kind of shuttering member is disclosed in its manual, it can be solid, also can be hollow, its profile can be made shapes such as rectangle, circle, polygon according to designing requirement.And for example the applicant is that ZL99249798.1, name are called " filling reinforced concrete fiber reinforcement type thin-wall member " utility model patent in the patent No. of application on November 29th, 1999, it discloses a kind of thin-wall mould-shell member, comprise upper base, on every side sidewall, go to the bottom, cavity, upper base, on every side sidewall, going to the bottom surrounds cavity each other.These shuttering members are inconvenience when the carrying construction, influences efficiency of construction.Therefore, develop a kind of cast-in-place concrete cored urgent need that has been.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-place concrete coredly, in cast-in-place process, the hollow unit in it has characteristics such as the carrying lifting is convenient, efficiency of construction is high, loss is little, labour intensity is little.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, Cavity structural member, Cavity structural member is wrapped up in and is contained in the steel bar concrete, Cavity structural member comprise upper base, on every side sidewall, go to the bottom, cavity, upper base, on every side sidewall, going to the bottom surrounds cavity each other, the cast-in-situ reinforced concrete rib that Cavity structural member forms for steel bar concrete each other, it is characterized in that upper base, on every side sidewall or go to the bottom at least one at least one concave pit is arranged, be provided with the suspender member that is lower than upper surface in the concave pit, an end of described suspender member has the rod member of reinforcing to link to each other.Like this, the performance of hanging of suspender member is strengthened, and has improved the ability of hanging of suspender member greatly, make Cavity structural member to hang performance more reliable.Because upper base, on every side sidewall or go to the bottom at least one at least one concave pit is arranged, be provided with the suspender member that is lower than the surface in the concave pit, thereby Cavity structural member is carried, lifts very convenient when the carrying construction, speed of application is fast, efficient is high, thereby has reached purpose of the present invention; Simultaneously, the lifting of Cavity structural member with pile up in the process, can not damage the carrying part by pressure or push up Cavity structural member badly placed on it because of the carrying part is outstanding; In addition, the carrying part can not hinder the laying of hollowcore slab reinforcing bar; And if suspender member is arranged on and goes to the bottom, after Cavity structural member is applied to floor, no longer need on floor, punches to get into the cave to install and state accessory, do not influence the attractive in appearance of ceiling, no longer need to repair, saved decoration cost; In addition, Cavity structural member also has characteristics such as simple in structure, that intensity is high, making is easy, cost is low, is applicable to the structure of various Cast-in-place Concrete Building Floor, roof system, body of wall, sole plate and road and bridge engineering, is specially adapted to hollow arch without beam.
Feature of the present invention is that also described suspender member is suspension ring or suspension hook.Like this, the diversity of suspender member can satisfy the needs of various different situations.
Feature of the present invention is that also described suspender member is arranged at the central authorities of upper base.Like this, the lifting that helps hollowcore slab with pile up, can not damage the carrying part by pressure or push up hollowcore slab badly placed on it because of the carrying part is outstanding.
Feature of the present invention is that also described suspender member links to each other with going to the bottom with upper base simultaneously.Like this, make floor or Cavity structural member be difficult for being damaged.
Feature of the present invention also is described thickness of slab of going to the bottom greater than the upper base and the wall thickness of sidewall on every side, upper base, sidewall and go to the bottom and contain reinforce on every side.Reinforce is that reinforcing bar, prestressed reinforcement, steel wire, steel fibre, fibre, bundle, steel mesh reinforcement, gauze wire cloth, fleece, nonwoven are gluingly arranged net, in the metal foil band, braid over braid, strap at least one.Like this, upper plate, contain above-mentioned reinforce in sidewall or the bridging piece on every side, their strength and stiffness have been improved greatly, make Cavity structural member cracky not in stacking, transportation, installation, work progress, even the breakage of small size is arranged, because of the connection of reinforce is arranged, do not need to repair yet, can continue to come into operation.
Feature of the present invention also be suspender member and upper base go to the bottom or its two in reinforce link to each other.Like this, Cavity structural member is more survivable, and it is more reliable that it hangs performance.
Feature of the present invention also is have reinforce to expose on the described Cavity structural member.Like this, have reinforce to expose on the Cavity structural member, when Cavity structural member was applied in the Cast-in-place Concrete Building Floor, reinforce and Cast-in-place concrete that it exposes combined, and can improve the bond stress between Cast-in-place concrete and the Cavity structural member greatly, optimized the performance of whole hollow building cover; Simultaneously, expose reinforce and also make things convenient for Cavity structural member when carrying, make handle or suspension ring or suspension hook and use.
Feature of the present invention is that also described going to the bottom stretch out on every side sidewall and constitute bridging piece.
