Description
(1) technical field
The present invention relates to a kind of mould with cavity structure for casting reinforced concrete floor 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 that shuttering member promptly constitutes all very smooth whole floor slab structure of upper and lower surface with reinforced concrete with cement, 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, 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 can bear bigger flooring stress and hanging constant weight does not ftracture as light fixture, ceiling fan, equipment, pipeline etc., therefore, develop a kind of novel mould with cavity structure for casting reinforced concrete floor slab for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of mould with cavity structure for casting reinforced concrete floor slab, have in light weight, characteristics such as intensity is high, simple in structure, convenient construction and transport, simultaneously, also have the object of hanging and in-situ deposited prefabricated bonding surface does not ftracture, base plate can transmit the characteristics such as power of ribbed slab floor.
Solution of the present invention is on the basis of existing technology, there is not ribs, it by upper base, go to the bottom and sidewall constitutes, sidewall all around and upper base, the totally-enclosed cavity type polyhedral structure of the formation of going to the bottom, it is characterized in that upper base and sidewall are the one-time formed whole peviform template that links together, going to the bottom is the structure base plate, and peviform template and structure base plate link the polyhedral structure that forms the sealed whole body cavity, and the thickness of slab of structure base plate is greater than the wall thickness of peviform template.Owing to there is not ribs, thereby the more existing shuttering member of weight is lighter, and simultaneously, going to the bottom is the structure base plate, and the thickness of slab of structure base plate is greater than the wall thickness of peviform template, and therefore, whole cavity Structural form intensity height, stressed power transmission are more reasonable, and simple in structure.During actual the use, the structure base plate can participate in stressed, and can hang the greater weight object and in-situ deposited prefabricated bonding surface does not ftracture, thereby has reached purpose of the present invention.
