Abstract
The utility model mainly discloses a composite floor large cantilever edge beam joint which comprises beams, edge sealing beams, inclined supports, frame beams, connecting plates and a composite floor. Each beam, the corresponding connecting plate and the corresponding inclined support form a triangular component taking the beam and the connecting plate as right-angle sides and taking the inclined support as an inclined side, a plurality of triangular components are welded on the frame beams connected with a building body, the edges of acute angle portions of the outer ends of the triangular components are sealed by the edge sealing beams, and the composite floor is laid on the frame beams, the beams of the triangular components and the edge sealing beams and fixed by fasteners. The problems of large steel dosage or difficulty in mounting and the like of a composite floor large cantilever edge beam are solved, cantilever capacity is enhanced, material consumption is reduced, and the joint is easy to manufacture and mount.
Description
Technical field
The utility model relates to steel building field, is specifically related to a kind of composite floor side bar node of encorbelmenting greatly.
Background technology
In building trade, the proportion that structural steelwork is occupied is increasing, particularly high level and super highrise building, and the ratio of application steel work is increasing.And in high-rise and super high steel structure, because the number of plies is more, steel column is stressed larger, so column section is all larger, the general length of side or diameter are not less than 1000mm.If side bar is not done bias, the floor on side bar is larger to the distance of external wall, and what have is not less than 600mm.High level and super highrise building, for accelerating construction progress, floor support plate reinforced concrete combination floor application is very extensive, and now the encorbelment research of floor node of side bar just seems particularly important.
In existing engineering treatment method, generally on post, add Cantilever Beams, between Cantilever Beams, to seal up again side bar, or directly with concrete slab self, encorbelment, the third mode is cantilever steel girder from side bar, seals up side bar between Cantilever Beams again.Before a kind of mode steel using amount increase obviously, the second way is when the rib of side bar and floor support plate is parallel, floor support plate is without supporting border, can downwarp obvious, the third mode needs Liang Liang to rigidly connect, construction is comparatively difficult.Therefore mainly solving, the application processes a difficult problem for this side bar node as optimum most economical mode how.
Utility model content
The purpose of this utility model is to provide a kind of composite floor side bar node of encorbelmenting greatly, solves the composite floor side bar steel using amount of encorbelmenting greatly large or the problems such as difficulty are installed, and has increased the ability of encorbelmenting, and saves material usage, is easy to fabrication and installation.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The composite floor side bar node of encorbelmenting greatly, is characterized in that: comprise crossbeam, edge sealing beam, bearing diagonal, frame beam, junction plate and composite floor; Crossbeam, junction plate, bearing diagonal form one and take the triangle component that crossbeam, junction plate be hypotenuse as right-angle side, bearing diagonal, on the frame beam being connected with building body, weld several triangle components, triangle component outer end acute angle portion is by edge sealing beam edge sealing, composite floor is laid on frame beam, triangle component crossbeam, edge sealing beam top, by fixture, fixes.
Described frame beam is i iron, and the junction plate of triangle component is connected to a side of i iron, and the opposite side of i iron is connected with auxiliary junction plate.
Described edge sealing beam is channel-section steel, and its web is towards outer encapsulating.
Described crossbeam is angle steel, and crossbeam and frame beam, edge sealing beam overlapping are cut limb, reaches crossbeam and frame beam, the concordant effect of edge sealing back portion.
The angle of described bearing diagonal and junction plate is between 30 degree ~ 60 degree.
Described bearing diagonal and edge sealing beam leave mounting distance.
Adopt after such scheme, the utlity model has many beneficial effects:
(1) can improve the side bar resistance to overturning of encorbelmenting;
(2) can effectively reduce crossbeam and edge sealing beam size;
(3) reduce structural steel amount;
(4) reduce installation difficulty;
(5) increase the side bar security performance of encorbelmenting.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model preferred embodiment;
Fig. 2 is the utility model preferred embodiment partial schematic diagram;
Fig. 3 is the generalized section of the utility model preferred embodiment;
Fig. 4 is the general illustration of the utility model preferred embodiment.
The specific embodiment
By reference to the accompanying drawings, to the utility model, preferred embodiment is described in further details.
In the present embodiment, be that frame beam 4 from building body connects the composite floor the side bar node of encorbelmenting greatly, the member being mainly concerned with comprises crossbeam 1, edge sealing beam 2, bearing diagonal 3, frame beam 4, junction plate 5 and composite floor 6.
Crossbeam 1, junction plate 5, bearing diagonal 3 form a triangle component, and crossbeam 1, junction plate 5 are that right-angle side, bearing diagonal 3 are hypotenuse.For easy for installation, the end of bearing diagonal 3 and crossbeam 1 leave certain distance.
On frame beam 4, by secondary beam 8 spacing, be connected with a plurality of triangle components, frame beam 4 in the present embodiment is i iron, wherein triangle component right-angle side junction plate 5 is connected to a side of i iron, opposite side at i iron, the junction plate 7 of corresponding secondary beam 8 and frame beam 4, prevents that by secondary beam 8 frame beam 4 from being turned round.
Crossbeam 1 should be selected angle steel, simultaneously in order to keep same edge sealing beam 2, frame beam 4 upper surface flush, facilitates composite floor 6 to install, and crossbeam 1 need be cut to limb with the overlapping portion of edge sealing beam 2, frame beam 4 top flanges, and excision thickness is greater than edge of a wing thickness 2mm separately.
Composite floor 6 is connected on the girder steels such as crossbeam 1, edge sealing beam 2 and frame beam 4 by shear connectors such as pegs.The utility model is mainly controlled according to composite floor 6 cantilever span L, and when frame beam 4 web heights are suitable with cantilever span L, bearing diagonal 3 angles are preferably 45 degree; If frame beam 4 web heights differ more than cantilever span L, the angle of bearing diagonal 3 and frame beam 4 upper junction plates 5 should be adjusted between 30 degree ~ 60 degree.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
