Abstract

Hollow floor slab of in-situ deposited steel bar reinforced concrete inlcudes in-situ steel bar reinforced concrete ribs and shuttering members, which are polyhedral structures by connecting basin like form board comprising peripheral side walls and upper base plate with lower base plate. It features that it has also in-situ deposited upper steel bar reinforced concrete plate, that the lower base plate of shuttering member serving also as structural bottom plate is thicker than the wall of the basin-like form board and is steel bar or wire reinforced, and that the basin-like form board is reinforced by various fiber. The hollow floor slab of in-situ deposited steel bar reinforced concrete has no crack between its structure bottom plate and prefabricated parts and can transfer the force of dense-rib floor board. In addition, it has high strength, simple structure, low cost and other advantages.

Description

A kind of cast-in-situ reinforced concrete hollow slab
(1) technical field
The present invention relates to a kind of cast-in-situ reinforced concrete hollow slab.
(2) background technology
Advantages such as at present, the building of brick mix structure and frame construction 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.The patent No. is " shuttering member " utility model patent of 93206310.1, a kind of a kind of prefabricated noggin piece that is used for industry and the close rib cavity of civilian construction floor is disclosed, it by upper base, go to the bottom and sidewall constitutes, sidewall all around and upper base, the totally-enclosed cavity polyhedral structure of the formation of going to the bottom are provided with the integrated support intensity of ribs with the enhancement mode mould component in the die housing.During construction, by designing requirement, shuttering member is placed on the supporter of floor gap, reserve the certain clearance space between shuttering member, arrange reinforcing bar, and pour into a mould with cement, form the cast-in-situ reinforced concrete rib, shuttering member promptly constitutes all very smooth whole floor slab structure of upper and lower surface with the cast-in-situ reinforced concrete rib, shuttering member in floor be internal mold be again to fill supporting member, construction saves trouble, easy.But this shuttering member is because there is ribs inside, weight is heavier relatively, carrying is difficulty, when being subjected to vibrating load or alternation load action, be prone to crackle between lower shoe and the cast-in-situ reinforced concrete rib, and the wall thickness of polyhedral structure not by actual loading and use need the design, promptly going to the bottom thickness of slab should be greater than other wall thickness, be beneficial to when reality is used, the object of going to the bottom and to bear bigger flooring stress and hanging constant weight, do not ftracture as light fixture, ceiling fan, equipment, pipeline etc., therefore, develop a kind of novel cast-in-situ reinforced concrete hollow slab for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-situ reinforced concrete hollow slab, has in-situ deposited prefabricated bonding surface and the structure base plate does not ftracture, base plate can transmit the characteristics such as power of ribbed slab floor, simultaneously, also has in light weight, characteristics such as intensity is high, simple in structure, easy construction.
Solution of the present invention is on the basis of existing technology, include the cast-in-situ reinforced concrete rib, shuttering member, the cavity polyhedral structure that peviform template that sidewall and upper plate constituted around shuttering member was served as reasons and lower shoe are formed by connecting, it is characterized in that also including the cast-in-situ reinforced concrete upper plate, the lower shoe of shuttering member is the structure base plate, the thickness of slab of structure base plate is greater than the wall thickness of peviform template, reinforcing bar or prestressed reinforcement are arranged in the structure base plate, steel mesh reinforcement or gauze wire cloth or two or more combinations have the aramid fiber glass fiber mesh in the peviform template, cloth, fibrous mesh cloth, gauze wire cloth, fibre nonwoven or fiber bundle or two or more combinations.Simultaneously, because the thickness of slab of structure base plate is greater than the wall thickness of peviform template, and reinforcing bar, steel mesh reinforcement etc. are arranged in the structure base plate, aramid fiber glass fiber mesh, cloth etc. are arranged in the peviform template, therefore, whole shuttering member intensity height, stressed power transmission are more reasonable, and simple in structure.When being applied to cast-in-situ reinforced concrete hollow slab, the structure base plate can participate in stressed, and can hang the greater weight object, and structure base plate itself and in-situ deposited prefabricated bonding surface do not ftracture, and can transmit the power of ribbed slab floor, simultaneously, owing to there is not reinforcing rib, thereby the more existing shuttering member of weight is lighter, is convenient to carrying and construction, thereby has reached purpose of the present invention.
Feature of the present invention also is on the peviform template reinforcing rib is arranged, and reinforcing rib is solid, hollow or fluted body.The strength and stiffness of peviform template are better like this, are difficult for breaking in carrying and the work progress.
Feature of the present invention also is dew muscle or the dew net that the structure base plate has reinforcing bar or prestressed reinforcement, steel mesh reinforcement or gauze wire cloth to stretch out.Reveal muscle like this or reveal net and can form integral body with the Cast-in-place concrete bonding better, improve overall performance, prevent structure base plate and cast-in-place and prefabricated bonding surface cracking effectively, transmit the power of ribbed slab floor.
Feature of the present invention is that also the structure base plate stretches out the formation bridging piece from the sidewall of peviform template, and the outer edge of the bridging piece that stretches out is straight line or curve or broken line.Bridging piece can be used as the stay in place formwork of cast-in-place close rib, and can prevent that to a certain extent the interface is in conjunction with the crack.
Feature of the present invention is that also the peripheral side of structure base plate is interior puncture dihedral, back taper, waveform, zigzag side.Can make the bonding between structure base plate and the Cast-in-place concrete better like this, improve overall performance, prevent effectively and disperse between formwork and the Cast-in-place concrete stress to concentrate, eliminate straight slit.
