Abstract
The utility model relates to a concrete beam provided with honeycomb round holes, wherein a plurality of honeycomb round holes are formed in the concrete beam; crossed reinforcement bars are arranged between the round holes; a steel sleeve is arranged in each honeycomb round hole; annular ear plates are arranged at the two ends of each steel sleeve; connecting ring plates are welded on the steel sleeves; connecting steel plates for connecting the connecting ring plates on the adjacent steel sleeves are arranged on the concrete beam; and shear resistance male pins are arranged on the connecting steel plates. According to the utility model, a plurality of dense pipelines of equipment can be combined and penetrate through the honeycomb round holes reserved at the web, at the same time, the steel sleeves are additionally arranged in the formed honeycomb round holes of the beam for the treatment of effective reinforcement for the hole weakened section of the web, so as to improve and better the integral carrying capacity and rigidity of the beam with the honeycomb round holes; and the carrying capacity and the rigidity of the beam with the honeycomb round holes are close to or higher than those of a solid web beam of the same sectional dimension, so that not only the structural safety is satisfied, but also the structural analysis is simplified, and the design control is convenient.
Description
Technical field
The utility model belongs to building engineering field, relates in particular to a kind of concrete beam with cellular circular hole.
Technical background
At present, along with national economy and science and technology development, the building large space is more and more; The Vierendeel girder span is increasing, and the equipment installation integrated level is increasingly high simultaneously, as according to traditional approach equipment installation being walked at the bottom of beam; Will " eat up " part building and use headway; For satisfying the increase that headroom requires can to cause again construction costs, and for large span spatial structure, the increase of construction costs is particularly responsive.
If from the honeycomb circle hole that the framework soffit of girder is reserved, walk, generally can practice thrift headway.But the soffit of girder is offered round hole or rectangle hole, all the stress concentration phenomenon can occur around the hole, and the bearing capacity of beam and rigidity will be affected, the safety of influence building.
Summary of the invention
To the problems referred to above, the utility model provides a kind of concrete beam with cellular circular hole, and this concrete beam not only satisfies supporting capacity and rigidity, and equipment installation is walked from beam, to reduce taking up room of equipment installation.
The technical scheme that the utility model provides is: a kind of concrete beam with cellular circular hole, offer some cellular circular holes on the said concrete beam, and dispose cross wise reinforcement between circular hole; Be provided with steel sleeve in each honeycomb circular hole, the steel sleeve two ends are provided with annular otic placode, are welded with the connection ring flat-plate on the steel sleeve, and concrete beam is provided with the connection steel plate that the connection ring flat-plate on the adjacent steel sleeve pipe is connected, and connect steel plate and are provided with the shearing resistance peg.
Cellular Circularhole diameter on the utility model concrete beam compares less than 0.4 with the deck-molding of concrete beam.
Said steel sleeve wall thickness of the utility model and steel sleeve diameter ratio are more preferably greater than 1/80.
The utility model to intensive and measure big equipment installation carry out comprehensive after; From the honeycomb circle hole that the soffit of girder is reserved, walk; Simultaneously; In the Honeycomb Beam circle hole that forms, set up steel sleeve,, can improve and improve Honeycomb Beam integrated carrying ability and rigidity so that soffit of girder perforate is weakened the treatment measures that effective reinforcement is carried out in the cross section; Make Honeycomb Beam supporting capacity and rigidity thereof near or surpass solid web girder with sectional dimension, can satisfy structural safety, again can the simplified structure analysis, be convenient to design control.
The utility model makes through connecting steel plate that shear resistant capacity is able to strengthen between hole; Connect steel plate and make steel sleeve be linked to be integral body, and connect steel plate and limited its lateral buckling distortion, therefore, connect steel plate relatively rotating between steel sleeve and concrete played effect of contraction by the concrete parcel; Simultaneously, peg has strengthened the collaborative work between them.So the relative slippage between steel sleeve and the concrete is effectively controlled, and has strengthened mutual compatibility of deformation ability, makes the reinforcement bunch tube resist moment of flexure jointly with concrete, has promoted the integral rigidity of Honeycomb Beam.Connect steel plate and be connected with steel sleeve through connecting ring flat-plate, damage is torn in the steel sleeve part when having avoided stressed; Annular otic placode and connection ring flat-plate are separated steel sleeve along its length, and the outer calculated length of steel sleeve steel plate face is reduced by half, and local stability is strengthened; The annular otic placode had both carried out spacing to steel sleeve along the cantilever thickness direction, can effectively avoid again distress in concrete occurring in the otic placode width range, had improved the shear-carrying capacity in hole weakening cross section; Connect steel plate and also can avoid sleeve pipe and concrete that relative sliding rupture does not take place, between weakening cross section and real abdomen cross section, played transitional function simultaneously.

The specific embodiment
Further set forth the utility model below in conjunction with accompanying drawing.Should be understood that these only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Referring to Fig. 1-3, offer some cellular circular holes 5 on the concrete beam 1 of the utility model, 5 configurations of circular hole cross wise reinforcement 3; Be provided with steel sleeve 2 in each honeycomb circular hole 5; Steel sleeve 2 two ends are provided with annular otic placode 7; Be welded with connection ring flat-plate 6 on the steel sleeve 2, concrete beam 1 is provided with the connection steel plate 4 that the connection ring flat-plate on the adjacent steel sleeve pipe 26 is connected, and connects on steel plate 4 and the steel sleeve 2 to be provided with shearing resistance peg 8.
Cellular Circularhole diameter on the utility model concrete beam compares less than 0.4 with the deck-molding of concrete beam.
Said steel sleeve wall thickness of the utility model and steel sleeve diameter ratio are more preferably greater than 1/80.
Instance 1
The Vierendeel girder of span 25.2m is according to using headroom to require to confirm that its solid web girder sectional dimension is 800x2100 (mmxmm); Require and blade diameter length ratio (d/H) requires to confirm that with hole center distance structure round hole dia is d=700mm according to equipment installation; Hole center to center distance is s=1400mm, and circular hole quantity is 10, arranges to bilateral symmetry with the beam mid point; And the hole is centered close on the beam center line, forms Honeycomb Beam.Confirm that according to the technical requirements of the utility model steel sleeve reinforcing structure steel sleeve 2 thickness are 20mm; Annular otic placode 7, connection ring flat-plate 6 and connection steel plate 4 thicknesss of slab are 20mm; Annular otic placode 7 highly is 150mm with being connected ring flat-plate 6, and connecting steel plate 4 width is 400mm, and shearing resistance peg 8 is 16200.Through analog detection, each item index all shows well, and macroscopic crack does not appear in the Honeycomb Beam surface.
