Abstract

The utility model relates to a compound roof beam with a reinforcing bar structure for separating the internal walls of high layer and super-high layer buildings at the building industry. The compound roof beam is mainly characterized in that an arch frame for a compound force-shearing barrel, a hanging-pulling web member, the compound force-shearing barrel with compression resistance and a vertical hanging rod are respectively welded at each position of a frame to be integration. While being used, the compound roof beam with the reinforcing bar structure is arranged at the desired position of the buildings and welded and fixed with a main wall to be cast with mass concrete to reach an integral structure with the internal wall and a beam.

Description

Compound roof beam of reinforcing bar structure

The utility model belongs to building field

In high level, super highrise building, the transfer mode of vertical and horizontal load is: flooring-filling beam-crossbeam-post (wall) at present.The span in house is big more, big depth of beam is also big more, that is to say, the clear height in room generally just has 1 meter thick floor building body rigidity of putting more energy into about 3 meters, yet the sidesway that the building takes place under the horizontal stress effect is mainly caused by the body of wall strain between the two-layer floor.In super highrise building,, be not enough to resist horizontal loading according to this design.The present age large bay high level, in the super highrise building technology, the major function of floor is to offset by wind and earthquake, the caused horizontal loading of blast.And the ratio of the thickness of floor and floor clear height is about 1:3, and this ratio very easily causes the deformation of wall between the two-layer floor under the horizontal stress effect, be directed at the building horizontal jitter.Developed a kind of interleaving steel truss structural system of steel work abroad at the end of the eighties, though it has taken into account the function of interior wall and flooring crossbeam, the mechanical structure imperfection uses steel more, the more high defective of cost.In order to solve the weak point that exists in the present building super highrise building, the utility model is ad hoc has counted a kind of bar construction composite beam.

The purpose of this utility model is, a kind of bar construction composite beam is provided, and it can remedy some major defects of existing floor slab structure, can be widely used in again in high level, superelevation layer and the general long span building thing.The utility model has adopted to hang to draw, encircle presses the mechanics principle that combines, and it is simple in structure, manufactures conveniently, and cost is low, can reduce the overall height in building effectively, the rigidity of the building body of having put more energy into greatly.

Referring to accompanying drawing

Fig. 1 is a front view of the present utility model

Compound roof beam of reinforcing bar structure described in the utility model is by framework (2), complex shear tube bow member (7), hangs and draw web member (5), resistance to compression complex shear tube (6), and spherical shell floor (3), Vertical suspending bars (4) forms, and it mainly is at the drift angle place, two of framework (2) upper end, adopts the mode of welding to be fixed with symmetrical hanging and draws web member (5); It hangs on the lower end bar that the other end that draws web member (5) is welded on framework (2); The two ends of complex shear tube bow member (7) are welded on respectively the place, base angle, both sides of framework (2) lower end; The junction welding of the centre of complex shear tube bow member (7) and resistance to compression complex shear tube (6); The upper end of framework (2) has a resistance to compression complex shear tube (6) and the reinforcing bar on framework (2) both sides to weld; One end of vertical suspension rod (4) is welded on upper its other end of complex shear tube (6) and is welded on the reinforcing bar of framework (2) base; On framework (2) upper and lower end face, place respectively interlayer spherical shell floor (3); Framework (2) two ends grafting muscle (1) inserts complex shear tube welding in body of wall and the body of wall, at first manufactures framework according to Len req in manufacturing, to hang respectively then each position of drawing web member, vertical suspension rod, complex shear tube bow member, resistance to compression complex shear tube, grafting muscle to be welded in framework makes its one-tenth as a whole, carry out concrete casting, spherical shell floor is positioned on the framework upper and lower end face again, carry out again concrete casting, become partition wall thereby reach composite beam, and the overall structure that becomes one with beam. In use, this composite beam mainly cuts off use according to required room usable floor area in the large bay to high level, Super High building separately, has changed the structure of just building interior wall from the beginning of laying foundation in the traditional architecture. That is to say: can be according to the required use room area size of oneself for each user of skyscraper, cut off use, simultaneously, this composite beam is owing to use spherical shell floor to do interlayer, so that beam and floor free height decrease, the weight of its building is decrease also.

Embodiment

Bar construction composite beam described in the utility model, in use, at first make framework according to Len req, to hang then and draw the principle of web member according to mechanics, on different angle lead frame, again respectively with vertical suspension rod, the complex shear tube bow member, the resistance to compression complex shear tube is welded on the framework, makes its one-tenth as a whole, puts on the building desired position, and carry out the monolithic concrete casting after fixing with main body wall welding, interlayer spherical shell floor with floor is positioned on the framework upper and lower end face again, carries out monolithic concrete casting once more and gets final product, thereby reach the overall structure that interior wall and beam become one.

Claims

1, a kind of high level, superelevation floor room bar construction composite beam for building of being used for, it is by framework, the complex shear tube bow member, hang compositions such as drawing web member, resistance to compression complex shear tube, it is characterized in that, the drift angle place, two of framework (2) upper end adopts the mode of welding to be fixed with hanging of symmetry and draws web member (5); It hangs on the following end bar that the other end that draws compound lever (5) is welded on framework (2); The two ends of complex shear tube bow member (7) are welded on the place, base angle, both sides of framework (2) lower end respectively; The junction welding of the centre of complex shear tube bow member (7) and resistance to compression complex shear tube (6); There is a resistance to compression complex shear tube (6) upper end of framework (2), with the reinforcing bar welding on framework (2) both sides; One end of vertical suspension rod (4) is welded on the complex shear tube (6); Its other end is welded on the base reinforcing bar of framework (2), and framework (2) is placed interlayer spherical shell floor (3) respectively on the upper and lower end face, and the grafting muscle (1) at framework (2) two ends directly inserts complex shear tube welding in body of wall and the body of wall.
