Description
(1) technical field
The present invention relates to a kind of concrete filled light hollow unit.
(2) background technology
Arch without beam is that present Cast-in-place Concrete Building Floor is used wider floor structural form, have that speed of application is fast, structure height is little, advantages such as ceiling decoration can be cut apart and need not to room area flexibly, the lightweight member of filling in it has various hollow sections and box, and box has hollow or solid.Is that ZL99232921.3, name are called " cast-in-place reinforced concrete filling thin wall cylinder " utility model patent as the applicant in the patent No. of application on March 10th, 1999, and it is made up of horniness thin-walled tube and two plugs, is applied to use as lightweight member in the arch without beam.The beam army in Shijiazhuang City, Hebei Province city and for example, the patent No. in application on February 23rd, 2000 is that ZL00203695.9, name are called the formwork that uses in " combination concrete hidden rib floor structure " utility model patent, Instructions Page 2 the 5th walk to the 7th line description " formwork can be solid; also can be hollow; light materials such as available plant straw, glass fiber reinforced plastic, sheet iron plate, glass fibre cement are made; its profile can be made shapes such as rectangle, circle, polygon according to designing requirement; ", being applied to equally make up in the concrete hidden rib superstructure also is to use as lightweight member.And for example publication number is that CN1356440A, name are called: " a kind of cover of storied building in space structure ", include shuttering member, cast-in-situ reinforced concrete main rib that formwork and structure base plate link, it is characterized in that also including the cast-in-situ reinforced concrete upper plate, and on same precast construction base plate, include at least 2 prefabricated hollow formworks alternately with at least one cast-in-situ reinforced concrete time rib, the sidewall of cast-in-situ reinforced concrete time rib and hollow mould shell is superimposed each other, and cast-in-situ reinforced concrete main rib, cast-in-situ reinforced concrete time rib constitute the staggered dark close rib structure of cover of storied building in space structure primary and secondary.The shuttering member that uses in this superstructure also is to use as lightweight member.And for example publication number is that CN1348044A, name are called: " a kind of steel bar reinforced floor slab in space structure formwork structural element ", it comprises upper base, go to the bottom, sidewall, by upper base, go to the bottom, sidewall constitutes enclosed cavity on every side, it is characterized in that at least one sidewall, also including module and at least one montant die cavity or brace die cavity or both combinations of at least one protrusion, and going to the bottom is the structure base plate, its thickness ratio upper base thickness of slab and the sidewall wall thickness is big all around.It is lighter relatively that this formwork structural element is applied to the floor structure weight that forms behind the cast-in-situ reinforced concrete floor slab in space structure, and have in light weight, characteristics such as intensity is high, simple in structure, convenient construction and transport, simultaneously, also have the cast-in-place and prefabricated bonding surface of hanging the bottom surface of cast-in-situ reinforced concrete floor slab in space structure behind the object and do not ftracture, can transmit the characteristics such as power of floor slab in space structure.This formwork structural element equally also is to use as lightweight member.But no matter be hollow section or box, be applied to superstructure as permanent lightweight member after, the stressed Force transmission parts of no superstructure in its member, particularly when the lightweight member size is big, show more obviously, simultaneously, the intensity of corresponding cast in site floor is relative with rigidity relatively poor.Japan Patent JP2001214562A, it discloses a kind of hollow concrete plate core, this core is provided with groove as lightweight member at end face and bottom surface, and lightweight member is provided with the cast hole of concrete, groove is communicated with the cast hole, like this, when lightweight member is applied to superstructure, though hole in the member and groove can form bracing piece or the pier and the reinforcing rib of Cast-in-place concrete, can become the stressed and Force transmission parts of superstructure, solve the problem that above-mentioned hollow section and box exist preferably.But this lightweight member is imbedded in the Cast-in-place concrete, and its manual is not described this effect, and the main content of its description and purpose are the sound insulation values that reduces the quality of hollow concrete plate and improve hollow concrete plate.And this lightweight member is the solid component that adopts the such class synthetic resin material foaming of poly-stupid vinylic foam to make, because this class lightweight member is the solid light member, thereby its material usage is big, corresponding cost height, and also Material Strength own is low, fireproof performance is poor.Therefore, develop a kind of novel concrete filled light hollow unit, for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete filled light hollow unit, after being applied to arch without beam, can significantly improve the mechanical property of superstructure, its shearing resistance, torsional property improve greatly, intensity and rigidity are greatly improved, simultaneously, the light hollow member also has characteristics such as simple in structure, that intensity is high, making is easy, cost is low.
Solution of the present invention is on the basis of existing technology, comprise the light hollow member, it is characterized in that at least one hole for in-site pouring concrete is arranged in the light hollow member, simultaneously, have at least one groove that is communicated with the cast hole on external surface of structural member, hole runs through the upper and lower surface of this light hollow member, and hole is at the upper and lower surface place of light hollow member both ends open, be the hole wall of sealing between the hole both ends open, the inner chamber of this sealing hole wall and light hollow member separates.Like this, owing on the light hollow member, there is the hole of Cast-in-place concrete cast usefulness to run through the light hollow member, after the light hollow member is applied to building cover structure, Cast-in-place concrete enters in the hole, after treating setting and harden, form Cast-in-place concrete post or pier, thereby in the light hollow member, formed the stressed and Force transmission parts of superstructure, improve the mechanical property of superstructure greatly, particularly improved the shearing resistance of superstructure, antitorque mechanical property greatly; Simultaneously, because at least one groove that is communicated with the cast hole is arranged on external surface of structural member, Cast-in-place concrete enters into reinforcing rib or the stiffening rib that has formed cast in site floor in the groove, thereby the intensity of superstructure and rigidity are greatly improved, thereby reached purpose of the present invention, the light hollow member also has characteristics such as simple in structure, that intensity is high, making is easy, cost is low simultaneously; In addition, the light hollow member is compared the described hollow concrete plate core of Japan Patent, its material usage is little, low price, corresponding cost is low, and its intensity is better than the intensity and the fireproof performance of the solid component of making of poly-stupid vinylic foam resinoid with fireproof performance, is applicable to the structure of various Cast-in-place concretes building (room) lid, body of wall and road and bridge engineering, is specially adapted to hollow arch without beam.
