Abstract
Bending moment applied to a beam causes out-of-plane deformation to a panel when the panel zone is hollow, and thereby a load bearing by a web cannot be expected in an elastic region. Since the section modulus of a beam end which is used in the structure calculation of a building structure is limited to the section modulus of only the flange not including the web, the beam end has a low strength. Therefore, a beam larger in size must be used and an extra beam depth is required, thus causing an increase in the weight of a steel beam. As the result of various studies, it has been found that various problems could be resolved by significantly increasing the plate thickness of a diaphragm in the direction of the web, and imparting prestress by hot working or overlaying the underside surface of the beam.
Description
Technical field
The present invention relates to the post beam junction surface structure of reinforcing bar works.
Background technology
With regard to the structure of building iron bone structure thing, under the situation that runs through the dividing plate form of using rectangular section column or circular cross-section post, as shown in Figure 1, dividing plate 1 by post 5, beam 4, plate 2 and perforation post 5 and plate 2 constitutes, beam flange 4F solder joints 7 is on the dividing plate of giving prominence to from post 51, and the soffit of girder 3 solder joints 3W are on plate 2.Also there is following form in this dividing plate, promptly use be not post connect but in insert in the internal partition form of the dividing plate in the post.In this case, the beam flange 4F and the soffit of girder 3 all solder joints on plate 2.As shown in Figure 2, the cross section at the post beam junction surface under the situation that runs through the dividing plate form generally is provided with arc notch 11, thereby the installation sealing wire 7 of the sealing wire 6 that makes plate 2 and dividing plate 1 and beam flange and dividing plate does not intersect.In addition, general with respect to all welding, with erection welding 8 backing plate 10 is installed.In addition, as shown in Figure 3, also exist and be called no arc notch method, the form at welded post beam junction surface without arc notch.In addition, as shown in Figure 4, also there is following method: with the no arc notch method that do not have arc notch that dividing plate 1 is not outstanding but terminate in the outside of post outside post, at the engaged at end beam flange of this dividing plate.In addition, as described in patent documentation 1, there is following method: dividing plate is made the through dividing plate mode that runs through of post, remove dividing plate outstanding from post, the welding of the welding of overlapping dividing plate and post and dividing plate and beam flange and make weld part integrated.

Problem to be solved by this invention
As shown in Figure 4, in the work on hand method, under the situation of utilizing plate 2 brace summer moment M, the moment 13 of beam end becomes maximum along with separating from the neutral position of beam 4 and becoming big at the beam lugs position, is under the situation of cavity at plate district 2Z still, with regard to the moment of flexure that relates to beam, the outer distortion 12 of plate 2 generating planes diminishes in soffit of girder position at elastic range, can not expect bearing of moment of flexure 13N.For this reason because the section modulus of beam-ends only becomes the section modulus of flange except the soffit of girder, so beam-ends specific strength is low mutually with the beam central portion, for this reason, will use than the beam of bearing the also big size of moment of flexure with the whole cross section of beam, need unnecessary depth of beam, reinforcing bar weight increases.
If there is backing plate, then between backing plate and beam flange and backing plate and dividing plate, produce a little gap, stress takes place to be concentrated, cause the reduction of intensity, and hinder ultrasonic test.
If with the no carriage method of non-bolt joint on beam bracket and the incorporate beam of central beam, in the post side backing plate is installed in advance, then spacing such as plan between the post are kept under the state of certain value, the soffit of girder become hinder and can not be on post mounting rail.
If just the dividing plate thickness of slab is increased about number mm and with this part and soffit of girder solder joints, then has only soffit of girder leg thickness partly to play moment of flexure and bear effect.In this case, because its weight increases, the effect of dividing plate thickening is reduced.
A plurality of beams are installed on identical plate, and under the depth of beam situation about differing from one another, when making the upper flange position consistency, the position difference of lower flange, correspondingly the number of dividing plate increases, and spends its cost of materials and installation fee and time.
Under the situation that depth of beam is reduced, because ground and load-carrying, the deflection of beam distortion becomes big.
In addition, in patent documentation 1, remove dividing plate outstanding from post, alleviate its stress and concentrate, and remove arc notch, alleviate its stress and concentrate.But with regard to the moment of flexure that relates to beam, the outer distortion 12 of plate 2 generating planes can not expect that in elastic range the soffit of girder bears.
Summary of the invention
The present invention makes in view of above situation, and its purpose is, in the structure of the post beam junction surface of reinforcing bar works, strengthens moment of flexure and bears big beam end, reduces depth of beam, reduces reinforcing bar weight.
This each problem in the result who carries out various researchs as can be known can be by following solution: the thickness of slab increase that makes dividing plate for example about 35mm more than, give predeformation etc. to carrying out hot line processing below the beam.
The described structure of the present invention of claim 1 is as follows, remove dividing plate outstanding from post, and the thickness of slab of dividing plate is increased significantly, the weld part of the weld part of axis of a cylinder and dividing plate and beam flange and dividing plate is overlapping and engage, and make to soffit of girder side and increase this thickening and the soffit of girder solder joints that is preferably the dividing plate more than the 35mm more than the 5mm.
Described first structure of the present invention of claim 1, at reinforced concrete column beam junction surface beam-ends, by removing dividing plate shown in Figure 2 outstanding 1A from post, reduce the weight of dividing plate, make the processing of the groove etc. of beam-ends become easy, preventing influences caused embrittlement with respect to the multiple heat of the weld part 7 of dividing plate, and the beam-ends machining under the situation of the thickness of slab that increases dividing plate becomes easy.If under the state that dividing plate is given prominence to from post, the thickness of slab of dividing plate is thickened to soffit of girder side, then need to carry out the incision of the beam flange and the soffit of girder, carry out complicated processing thereby force.In order to remove the outstanding 1A of dividing plate from post, need prevent that stratiform that the welding by dividing plate causes from spreading splits, and its Sulfur partly need be reduced to below 0.008%.Preferably its Sulfur partly is reduced to below 0.004%.The second, the thickness of slab of dividing plate is thickened more than the 5mm to soffit of girder side, be to need as the minimum value that in the welding of beam flange 4F and dividing plate, can place welding bead and at the permissible value of the installation accuracy of dividing plate 1 loading girder flange 4F.This structure in combination not from the outstanding dividing plate of post and dividing plate to having novelty aspect the thickness of slab increase of soffit of girder side.
Described second structure of the present invention of claim 1, the weld part of the weld part of axis of a cylinder and dividing plate and beam flange and dividing plate is overlapping and engage, and make this thickening and the direct solder joints of the soffit of girder of the dividing plate that increases to soffit of girder side.Otherwise, will separate the weld part of axis of a cylinder and dividing plate and the weld part of beam flange and dividing plate, the thickness of slab of dividing plate 1 is also increased to the outside of beam, thereby increase separator.Even this is specially to reduce depth of beam and beam weight is reduced, its effect is reduced.In the beam flange inner, make this thickening and the soffit of girder solder joints of the dividing plate of increase, the moment of flexure that puts on the soffit of girder is delivered on the dividing plate.Has novelty aspect this thickening that makes the dividing plate that increases to soffit of girder side and the direct solder joints of the soffit of girder.
Thus, bring the thickness of slab of beam flange to increase or the effect of the increase of soffit of girder thickness of slab, bring the yield strength of beam flange end to increase or the yield strength of soffit of girder end increases, can bear load, can use the more beam of low height thus with respect to the bigger moment of flexure of beam.
The described structure of the present invention of claim 2 is on the basis of the structure of the described invention of claim 1, it is characterized in that: to beam in abutting connection with and more the beam of low height carry out the lower flange of beam-ends is sidelong big processing downwards and the haunch that replenishes web is handled, make the depth of beam unanimity of the beam end at post beam junction surface.On the basis of the structure of the invention of claim 1, it is characterized in that: to the beam of the invention of claim 1 in abutting connection with and more the beam of low height carry out haunch and handle, make the depth of beam unanimity of beam end at the post beam junction surface in identical plate district.By carrying out that haunch is handled and depth of beam increases, at the downside of the dividing plate of the lower flange that big depth of beam has been installed, the lower flange of can the mounting rail height little beam.If be installed on the dividing plate downside of the lower flange of big depth of beam, then, can expect that the moment of flexure of the soffit of girder is born according to the increase of depth of beam and the slab effect of dividing plate that the lower flange of big depth of beam is installed.In addition, little beam need be installed on the lower flange of big depth of beam,, then can be installed on the position arbitrarily of dividing plate if the moment of bearing with the end of little beam is sufficient value, rather than the downside of this dividing plate.
Handle by carrying out this haunch, the depth of beam of littler beam-ends increases, and at the downside of the dividing plate of the lower flange that big depth of beam has been installed, the lower flange of little beam is installed.If little beam is installed on the dividing plate downside of the lower flange of big depth of beam, then, can expect that the moment of flexure of the soffit of girder is born according to the increase of depth of beam and the slab effect of dividing plate that the lower flange of big depth of beam is installed.
The described structure of the present invention of claim 3, on the basis of the structure of claim 1 or 2 described inventions, it is characterized in that: by on the beam length central portion or below solder joints band steel, riser or shaped steel, or below beam length direction central portion, carry out hot line processing and make beam distortion upward in advance, or additional bead welding and make beam distortion upward in advance, thereby suppress deflection of beam.
