Abstract

The present invention discloses a reinforced concrete assembled integral lattice type vertical member open-web grid-frame floor structure. It is composed of reinforced concrete lattice type vertical member open-web grid-frame and cover plate connected in the top portion of reinforced concrete lattice type vertical member open-web grid-frame. The reinforced concrete lattice type vertical member open-web grid-frame is made up by using at least four prefabricated checkered frame through a certain splicing process.

Description

The steel reinforcement assembling integral structural vertical pole hollow rack building floor slab structure
Technical field:
The present invention relates to a kind of building cover structure, it is a kind of steel reinforcement assembling integral structural vertical pole hollow rack building floor slab structure.
Background technology:
The steel bar concrete hollow rack is the novel long-span floor system structure of China's the mid-80 in last century exploitation, it is made up of to intersection steel bar concrete Vierendeel truss shown in Figure 1 two, begin to be applied to engineering practice in the phase at the beginning of the nineties in last century, athletic training shop, Anshun City, Guizhou Province superstructure as building up in 1991 is the steel bar concrete hollow rack structure of orthogonal-diagonal lattice; And for example nineteen ninety-five the comprehensive superstructure in middle school, Bao'an, Shenzhen that builds up, be oblique crossing inclined steel bar concrete hollow rack structure; The Eurasian sales field (supermarket) in the Guiyang City, Guizhou Province Youth Palace superstructure one deck roof system that built up in 1996 and Changchun is the steel bar concrete hollow rack structure of orthogonal spatial.These large-span steel-reinforced concrete hollow rack structures are made the building superstructure and have been obtained remarkable social benefit and economic benefit, but these steel bar concrete hollow racks are in-situ casting, not only need a large amount of template turnovers, and site operation is also time-consuming.
Summary of the invention:
The objective of the invention is to: provide a kind of and save template, saving of work and time, the fast steel reinforcement assembling integral structural vertical pole hollow rack building floor slab structure of construction speed, thereby overcome the deficiencies in the prior art.
The present invention is achieved in that it is made of steel bar concrete structural vertical pole hollow rack (1) and the cover plate (2) that is connected steel bar concrete structural vertical pole hollow rack (1) top, and wherein steel bar concrete structural vertical pole hollow rack (1) is spliced by at least 4 prefabricated square shape frameworks (3).
Montant (4) at each square shape framework (3) is gone up the reinforcing bar that is reserved with varying number according to stressed size, interconnects by reinforcing bar and the second pouring concrete of reserving (5) between the square shape framework (3).
The profile physical dimension of each square shape framework (3) is identical.
The montant (4) of square shape framework (3) is the structural vertical pole of four limbs bar or six zeugopodiums.
Cover plate (2) can be steel bar concrete precast plate or glass plate.
On square shape framework (3), be provided with hole (6).
Compared with prior art, steel bar concrete structural vertical pole hollow rack of the present invention is to cast concrete in the crosspoint by reinforcing bar and secondary by some prefabricated square shape frameworks to be connected to form integral body, single square shape framework is transported to job site assembling global formation then in the prefabricated shaping of precasting yard.Because the profile physical dimension of each square shape framework is identical, a cover template can be produced several square shape frameworks, not only can save a large amount of templates, and saving of work and time, construction speed are fast.In addition, montant of the present invention is the structural vertical pole of four limbs bar (two to hollow rack) or six zeugopodiums (three-dimensional hollow rack), compare with existing single limb montant, the bigger Moment at End of former single limb montant is converted into axially the drawing of each zeugopodium, pressure, the rod member internal force of stressed complexity is simplified, the stressed of whole hollow rack more becomes rationally, further improves the shear stiffness of structure; And improved node arrangement of reinforcement structure, further save steel.

The specific embodiment:
Embodiments of the invention: as shown in Figure 4, it is made of steel bar concrete structural vertical pole hollow rack 1 and the cover plate 2 that is connected steel bar concrete structural vertical pole hollow rack 1 top, and cover plate 2 can adopt steel bar concrete precast plate or glass plate (daylighting roof); Steel bar concrete structural vertical pole hollow rack 1 is spliced into latticed by several prefabricated square shape frameworks 3, each grid is made of to intersecting or being intersected by 6 square shape framework 3 three-dimensionals 3 liang of 4 square shape frameworks, and the size of square shape framework 3 and number needs are determined as calculated according to the span of superstructure; The profile physical dimension of each square shape framework 3 is identical, is reserved with the reinforcing bar of varying number according to stressed size in the position, upper, middle and lower of the montant 4 of each square shape framework 3; Stressed each different square shape framework 3 adopts the numbering form to illustrate when prefabricated, unit in charge of construction is according to the assembly drawing of design, after the square shape framework 3 of when constructing at the scene difference being numbered sets up by assembly drawing, the reinforcing bar of reserving on the montant 4 is connected to each other, secondary is cast then, form second pouring concrete 5, after maintenance, remove scaffold, promptly form steel bar concrete structural vertical pole hollow rack 1, at steel bar concrete structural vertical pole hollow rack 1 loam cake upper cover plate 2, promptly obtain steel reinforcement assembling integral structural vertical pole hollow rack building floor slab of the present invention then.
When the plane of superstructure is square or the ratio of long limit, its plane and minor face when being less than or equal to 1.5, steel bar concrete structural vertical pole hollow rack 1 adopt as shown in Figure 6 two to the orthogonal spatial structure, the montant 4 of its square shape framework 3 is formed structural vertical pole by the four limbs bar; When the ratio of long limit, the plane of superstructure and minor face greater than 1.5 the time, the orthogonal-diagonal lattice structure that steel bar concrete structural vertical pole hollow rack 1 adopts as shown in Figure 7, the montant 4 of its square shape framework 3 is still formed structural vertical pole by the four limbs bar; When the plane of superstructure was hexagon or circle, steel bar concrete structural vertical pole hollow rack 1 can adopt the oblique crossing inclined structure of three-dimensional as shown in Figure 8, and the montant 4 of its square shape framework 3 is formed structural vertical pole by six zeugopodiums; When the span of superstructure is big, for further alleviating the weight of steel bar concrete structural vertical pole hollow rack 1, on square shape framework 3, have some holes 6, its structure is as shown in Figure 9.
