Description
(1) technical field
The present invention relates to a kind of steel bar reinforced floor slab in space structure formwork structural element.
(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 two-way ribbed 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 after this shuttering member is applied to the cast-in-situ reinforced concrete floor slab in space structure, the floor structure weight that forms 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 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 floor slab in space structure and be urgent need with the formwork structural element.
(3) summary of the invention
The object of the present invention is to provide a kind of steel bar reinforced floor slab in space structure formwork structural element, it is lighter relatively to be applied to the floor structure weight that forms behind the cast-in-situ reinforced concrete floor slab in space structure, and self 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.
Solution of the present invention is on the basis of existing technology, it includes upper base, go to the bottom, sidewall, upper base, go to the bottom and all around sidewall constitute enclosed cavity, 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.Since around sidewall the module of protrusion and montant die cavity, brace die cavity or montant die cavity and the brace die cavity that is made of module or module and sidewall are arranged, like this after this formwork structural element is applied to steel bar reinforced floor slab in space structure, promptly become truss member type two-way ribs by the Cast-in-place concrete two-way ribs that forms between the formwork structural element in the floor, or the two-way ribs of truss-like rod member is worn in the two-way ribs both sides, thereby the weight of cast-in-place two-way ribs alleviates greatly, also makes the weight saving of whole floor structure.Simultaneously, going to the bottom is the structure base plate, the thickness of slab of structure base plate greater than around the wall thickness of sidewall and upper base, thereby whole formwork structural element 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 the cast-in-place and prefabricated bonding surface of the bottom surface of cast-in-situ reinforced concrete floor slab in space structure does not ftracture, thereby has reached purpose of the present invention.Simultaneously, the formwork structural element also has in light weight, characteristics such as intensity is high, simple in structure, convenient construction and transport.
