Description
(1) technical field
The present invention relates to a kind of steel bar reinforced floor slab in space structure.
(2) background technology
Advantages such as at present, the building of brick mix structure and reinforced concrete structure 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, forming the cast in place reinforced bar concrete hidden rib, shuttering member promptly constitutes all very smooth whole two-way floor slab with hidden and dense ribs structure of upper and lower surface with reinforced concrete.But the two-way dark close rib weight of this cast-in-situ reinforced concrete floor slab in space structure is relatively large, thereby the floor structure weight that forms is heavier relatively, and cost is also higher relatively, therefore, develops a kind of novel cast-in-situ reinforced concrete floor slab in space structure for being badly in need of.
(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, have in light weight, characteristics such as cost is low, intensity is high, simple in structure, easy construction.
Solution of the present invention is on the basis of existing technology, include shuttering member, the cast in place reinforced bar concrete hidden rib, shuttering member is by upper base, go to the bottom, sidewall is formed, upper base, go to the bottom and all around sidewall constitute the enclosed cavity structure, it is characterized in that also including the cast-in-situ reinforced concrete upper plate, the module that at least one protrusion is arranged at least one sidewall of shuttering member, the cast in place reinforced bar concrete hidden rib is the dark rib of web-type of dark rib of truss member formula or side band truss member, and concrete or steel bar concrete in montant in the truss member or brace montant die cavity that to be the module protruded by the sidewall of the shuttering member of arranging in floor or module constituted with sidewall or brace die cavity or the die cavity that both make up form.Like this, montant die cavity, brace die cavity or montant die cavity and brace die cavity that module of being protruded by the shuttering member sidewall or module and sidewall are constituted, after the floor pour concrete, just formed the dark rib of Cast-in-place concrete truss member formula, or the dark rib of web-type of side band truss member, thereby the weight of cast-in-place dark rib alleviates greatly, also makes the weight saving of whole floor structure.Simultaneously, have also that cost is low, intensity is high, characteristics such as simple in structure, easy construction, reached purpose of the present invention.
Feature of the present invention is that also going to the bottom of shuttering member is the structure base plate, the thickness of slab of its thickness ratio upper base and the wall thickness of sidewall is big all around, and the structure base plate has reinforcing bar, steel mesh reinforcement or gauze wire cloth, or the muscle of revealing is arranged or reveal net.Owing to go to the bottom and be the structure base plate, the thickness of slab of structure base plate greater than around the wall thickness of sidewall and upper base, simultaneously, the structure base plate has reinforcing bar or steel mesh, 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 bottom surface of cast-in-situ reinforced concrete floor slab in space structure, and particularly cast-in-place and prefabricated bonding surface does not ftracture.
Feature of the present invention is that also the cross sectional shape of montant in the dark rib or brace is square, circular, oval, semicircle or other shape.And it is identical with the cross sectional shape of montant die cavity in the shuttering member or brace die cavity.
Feature of the present invention also is the upper and lower position transition region concrete flare structure of montant and brace.And it is identical with upper and lower mouthful shape of the montant die cavity of shuttering member or brace die cavity.Flare both had been convenient to the cast of concrete, also can eliminate montant and brace and concentrate at the stress at the position of turning round.
Feature of the present invention is that also montant or the brace in the dark rib is pre-montant die cavity or prefabricated montant in the brace die cavity and prefabricated brace built in shuttering member.Can guarantee that like this concrete quality in prefabricated montant or the prefabricated brace is even, reliable.
Feature of the present invention is that also prefabricated montant or brace are prefabricated reinforced concrete montant or brace, and the dew muscle is arranged.Like this, prefabricated montant and prefabricated brace and cast-in-situ reinforced concrete are bondd well, improve the strength and stiffness of dark rib of truss member formula or the dark rib of truss member compound plate formula, improve its overall performance.
