Abstract
The utility model discloses a beam-column joint reinforced structure adopting a enlarging section method. The beam-column joint reinforced structure comprises an original column body and an original beam; an enlarging-section beam is arranged below the original beam; a steel sleeve hoop is fixedly connected at the connecting joint position of the original column body and the enlarging-section beam through chemical anchor bolts; the steel sleeve hoop is sleeved on the original column body; the upper edge of the steel sleeve hoop is positioned below the original beam; a novel reinforcement longitudinal bar parallel to the original beam is cast inside the enlarging-section beam; a hook parallel to the outer surface of the steel sleeve hoop is arranged at the end portion of the novel reinforcement longitudinal bar; the hook is fixedly connected onto the outer surface of the steel sleeve hoop through welding; and a bonded steel glue layer is arranged between the original column body and the steel sleeve hoop which are fixedly connected through the steel glue layer. As holes need not be drilled on the beam, bars need not be implanted on the beam and reinforcing steel bars need not be cut off and reconnected, the beam-column joint reinforced structure is simple and convenient in construction, labor-saving and material-saving. Besides, the beam-column joint reinforced structure is extremely favorable for the effect of structural reinforcement because a plurality of comparatively deep holes need not be drilled on an original column, and the novel reinforcement longitudinal bar need not be cut off and reconnected.
Description
Technical field the utility model relates to a kind of construction reinforced structure, particularly a kind of structure for strengthening node of beam column by section increase.
Often adopt the enlarging section method that the original structure beam is reinforced in the construction of background technology concrete structure reinforcement, increase depth of beam and width, newly join at the bottom of the beam, back and beam side longitudinal reinforcement, the longitudinal reinforcement of newly joining need carry out anchor connection with the former frame column at beam two ends, conventional way is to cut in two newly joining reinforcing bar, adopt electric hammer on post, to punch, the method of two sections reinforcing bars by bar planting is anchored at respectively in two newel posts, the reinforcing bar middle part connects again, or on post, get through hole, whole reinforcing bar passed this through hole, and reperfusion structure glue or pea gravel concreten carry out anchoring in the hole.
There are some problems in above construction, connect at the middle part again after the bar planting anchoring separately if reinforcing bar cut in two, will satisfy " Code for design of concrete structures " (GB50010-2002) some regulations of 9.4.2 bar, must not adopt the colligation lap joint under the part situation, must adopt the method for welding or mechanical connection, the construction trouble, the expense of taking a lot of work material, also to satisfy " concrete structure engineering construction quality standards of acceptance " (GB50204-2002) joint area percentage of the longitudinal stress reinforcing bar of middle regulation simultaneously, then must calculate blank size, cause the construction trouble equally, the expense of taking a lot of work material, therefore, in case there is jointing to occur, the problem that cost and duration increase must appear, also every vertical muscle all exist joint very unfavorable to the integrated member consolidation effect, quality is difficult to obtain control.
In addition, usually run into three, four beams of ining succession around the pillar in the construction and all want enlarging section, the vertical muscle that these several beam enlarging sections are newly joined generally all is positioned at same horizontal plane, if get through that reinforcing bar is worn in the hole then conflict mutually in several directions hole, reinforcing bar can't pass, and especially double muscle is difficult to when arranging realize especially.Bar planting also is difficult to realize if several directions are holed simultaneously, because it is generally darker according to the bar planting degree of depth that " concrete structure reinforcement design specifications " (GB30367-2006) designs, the pillar sectional dimension often can't satisfy the drilling depth of several directions bar planting simultaneously, conflict each other in the bar planting hole, reinforcing bar also can't be put into the hole, moreover it is, bigger to former post damage if punching also breaks into loose zone with the whole cross section of former post too much easily.
Even consider under more satisfactory situation, run in succession around the pillar three, four beams are all wanted enlarging section, these several beams are because depth of section is inconsistent, the vertical muscle of newly joining is not positioned at same horizontal plane, get through that reinforcing bar is worn in the hole or bar planting can not clash this moment, theoretical feasible, if but former column section is bigger, the hole of getting through hole or bar planting needs is generally darker, and length usually surpasses 500mm, and diameter is generally greater than 25mm, if the main muscle of former post, stirrup is arranged comparatively intensive, be easy to when then punching run into the post reinforcing bar and be difficult to pore-forming, often need repeatedly to attempt, time-consuming and damage former post easily.Can comprehensive above the analysis if want to adopt present conventional method anchor bar, be not only to consider duration cost size issue, under a lot of situations be realize the problem of constructing.
The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of structure of bean column node place's reinforcing bar anchoring when being used for the enlarging section method and reinforcing the building beam is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of structure for strengthening node of beam column by section increase, comprise former cylinder, Yuan Liang, it below former beam the enlarging section beam, it is characterized in that: be fixedly connected with steel hoop with the position of joints that the enlarging section beam is connected by chemical anchor bolts at former cylinder, steel hoop is enclosed within on the former cylinder, the upper edge of steel hoop be positioned at former beam below; Be cast with in the described enlarging section beam with former Liangping row newly join vertical muscle, the end of newly joining vertical muscle is provided with the crotch parallel with the steel hoop external surface, crotch is fixedly connected by welding on the external surface of steel hoop; Between former cylinder and steel hoop, be provided with the steel bonding glue-line, fixedly connected by the steel bonding glue-line between former cylinder and the steel hoop.
Preferably, described newly join vertical muscle below be provided with angle steel, a face of angle steel is welded on the external surface of steel hoop, another face of angle steel with newly join vertical muscle welding.
Preferably, described steel hoop is provided with hole for injecting glue and steam vent.
Preferably, at the position that described steel hoop and former cylinder, Yuan Liang join, and the plate joint position that forms steel hoop is equipped with the band that is made of rapid hardening pressure-resistant seal glue.
The beneficial effect of a kind of structure for strengthening node of beam column by section increase of the utility model is, makes under the situation that many beams and post intersect, and adopts enlarging section method construction reinforcements to become possibility to these beams; Owing to not be used in the bar planting of holing on the beam, need not block connection again, easy construction, labor and material saving to reinforcing bar; Do not need the more darker hole of former cylindrical drill, the vertical muscle that does not need newly to join blocks connection again, and is highly beneficial for the effect of structural strengthening.
