Abstract

The utility model relates to a high-performance building laminated board used for a structure of a prestress laminated building top, which comprises a board body of which the middle part is provided with a hollow hole along the longitudinal direction. Both sides of the board body are provided with wing margins, and the lower part of the board body is buried with steel bars, and moreover, both ends of the board body are provided with outward extending steel bars. The utility model has the advantages of reasonable structure, and convenient construction. The arranged wing margin can replace the traditional seam beam, and a dark beam is formed; the board body is a hollow structure, and has good strength and rigidity, so that the plate body can be suitable for being made by a wide span laminated board, however, the protruding steel bar and the beam are poured into integration, which enhances the lacing function of a beam slab and enhances the structural integrity. The utility model can be widely used for road bridge engineering field, the water conservancy engineering field, etc.

Description

The high-performance building superimposed sheet

The utility model relates to a kind of high-performance building superimposed sheet that is used for the superimposed building cover structure of prestressing force, relates in particular to a kind of high-performance long span building superimposed sheet, belongs to a kind of construction.This member also can be applicable to engineering fields such as bridge, water conservancy.

The superimposed superstructure that makes up building comprise by supporting beam, superimposed sheet and after the overlapping layers that waters above superimposed sheet constitute, existing superimposed sheet mostly is plate shaped, when not only constructing interim support need be set, difficulty of construction is big, and superimposed sheet is solid section, and from great, rigidity is lower.In Chinese patent CN2261462Y, announced the superimposed building cover structure of a kind of high efficient prestress, this structure has proposed a kind of enhancement mode superimposed sheet with ribbing, interim support when this superimposed sheet can be exempted the superimposed sheet construction, simplified technology, also make the rigidity of superimposed sheet and intensity obtain enhancing simultaneously, but this plate has been a solid section, from great, make its span be subjected to certain limitation, in addition, also desirable not to the utmost in the structure of plate-girder junction.

The purpose of this utility model is to provide a kind of high-performance building superimposed sheet at the deficiency of above-mentioned existing technologies existence, and it is not only rational in infrastructure, has higher strength and stiffness, can be suitable for large span, and easy construction.

The utility model is realized by following technical scheme: include plate body 2, its difference is to be vertically arranged with hollow hole 1 at the plate body middle part, the both sides of plate body are provided with the edge of a wing 4, are embedded with reinforcing bar 3 in the bottom of plate body, and are provided with vertical protruding bar 5 at the plate body two ends.

Good effect of the present utility model is: 1, both sides at plate body are provided with the edge of a wing, and in the edge of a wing arrangement of reinforcement, alternative traditional plate seam beam, not only can be convenient to the construction of superimposed superstructure, and cast-in-place back forms dark beam, strengthened the drawknot effect of beam slab, improved the globality of structure, can be used for height degree of splitting earthquake areas: can bear concentrated load in addition, and substitute bright beam, form the space attractive in appearance that large span does not have the roof, Liangping: 2, hollow hole is set, make corresponding the alleviating of plate body deadweight, and the height in plate body cross section can correspondingly increase, and the rigidity of structure is improved, thereby strengthens the application span of superimposed sheet; 3, the protruding bar that certain-length is set at the plate body two ends when construction and beam water and build up an integral body, the hollow hole at two ends also can form certain tenon effect simultaneously, form the fixed end structure with beam, the water resistance that can improve shear resistance 4, iterative structure can be further improved.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include the plate body 2 of a rectangle, the middle part of plate body longitudinally is provided with hollow hole 1, hollow hole is for connecting the through hole of plate body, the interruption hole of stopping up in the middle of also can be, width hollow hole according to plate body can be provided with 1-18, parallel along the longitudinal, hollow hole be shaped as circular or oblate type or other polygon, the recessed formation edge of a wing, the both sides of plate body 4, the bottom on the edge of a wing can flush with the plate body bottom, also can be positioned at middle and lower part, plate body both sides, side, the edge of a wing slightly is inclined upwardly, simultaneously two sides of plate body also slightly be inclined upwardly (big down little), should keep certain roughness above the plate body He above the edge of a wing, the concavo-convex difference of matsurface is 4-6mm, in the plate body bottom and the edge of a wing, be embedded with two-way in length and breadth reinforcing bar 3, the two ends that longitudinal reinforcement extends plate body form vertical protruding bar 5, and vertically the length of protruding bar is 100-300mm, in addition, transverse reinforcement also can be extended out the side direction on the edge of a wing, constitute side direction protruding bar 6, usually, the thickness of superimposed sheet is 40mm-350mm, length is 1800-15000mm, and width is 300-1800mm.

Its two ends were held on 9 beams of built-in cage of reinforcement 10 when the utility model used construction, vertical overhanging steel 5 muscle stretch into the face of building of beam, dispose the reinforcing bar 8 of some in the overlapping layers according to circumstances, thereafter concreting on them forms overlapping layers 7, constitutes the superimposed superstructure of whole shape thus, wherein each superimposed sheet laterally closes up splicing, the edge of a wing 4 forms grooves, be convenient to overlapping layers combine and form dark beam, as described in Fig. 4,6.The utility model and shear wall in length and breadth to connection status shown in Fig. 5,7, bury the reinforcing bar 8 of cross-over connection two plates above between two superimposed sheets underground, the shear wall cage of reinforcement 12 that waters after vertical protruding bar 5 at two ends stretches into, poured concrete links into an integrated entity overlapping layers 7, superimposed sheet 2 and shear wall 11.
