Abstract
The utility model discloses a connection structure of concrete beam has taken shape and newly-increased concrete beam, including the concrete beam that has taken shape and newly-increased concrete beam, be provided with reinforcing bar A in the concrete beam that has taken shape, implant reinforcing bar B in the newly-increased concrete beam back, reinforcing bar B passes through the bolt fastening in the concrete beam that has taken shape, makes and increases concrete beam and an overall structure of concrete beam formation that has taken shape, reinforcing bar B in the newly-increased concrete beam plants and passes through the bolt fastening behind the concrete beam that has taken shape. The utility model can ensure that the anchoring degree of the stress steel bar of the newly added beam meets the standard requirement, can be better connected with the beam structure, and simultaneously, the construction of the newly added beam is simpler and more convenient, thereby being beneficial to the engineering construction progress and ensuring the construction quality; meanwhile, the damage to the original beam structure concrete and the reinforcing steel bars can be avoided as much as possible, the stability of the beam structure concrete and the reinforcing steel bars is ensured, and the beam structure concrete and reinforcing steel bar composite material has a wide application prospect.
Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, particularly relates to the syndeton of a kind of beam of forming concrete and newly-increased concrete beam.
Background technology
In hydraulic structure; usually appearing on the beam concrete structure that has been shaped needs newly-increased slab and girder as the expansion of structure; now; the reinforcing bar of newly-increased concrete structure needs to stretch in the beam concrete be shaped, prior art due to the cross dimensions of beam own less, structural strength, rigidity are also lower; as other newly-increased girder constructions need be connected; then reinforcing bar anchoring in beam of newly-increased beam is comparatively difficult, and anchorage length can not meet code requirement, makes its connecting portion steadiness poor.Simultaneously because beam upper part concrete peeled off by needs, the Stability Analysis of Structures of beam own is also had a certain impact.
Utility model content
For solving the problem, the utility model provides the syndeton of a kind of beam of forming concrete and newly-increased concrete beam.Thus make the anchoring degree of newly-increased beam stress reinforcing bar meet code requirement, better can be connected with girder construction, reduce the destruction to original girder construction, ensure that it is stablized.
The utility model is achieved by following technical solution.
The syndeton of a kind of beam of forming concrete and newly-increased concrete beam, comprise forming concrete beam and newly-increased concrete beam, reinforcing bar A is provided with in the described beam of forming concrete, post-installing rebar B in described newly-increased mixed earth beam, described reinforcing bar B is bolted in forming concrete beam, makes increasing concrete beam and forming concrete beam form an overall structure.
Reinforcing bar B in described newly-increased concrete beam plants and is bolted through after forming concrete beam.
Described reinforcing bar A is connected in length and breadth and is arranged in forming concrete beam.
The beneficial effects of the utility model are:
Compared with prior art, the utility model can make the anchoring degree of newly-increased beam stress reinforcing bar meet code requirement, can better be connected with girder construction, ensures the stressed according calculation model of binding site; Make the construction newly increasing beam more simple, convenient simultaneously, be conducive to engineering construction progress, ensure construction quality.Implant reinforcing bar and arrange that boring is implanted according to newly-increased girder construction principal rod, anchoring is forced through screw bolt reinforcing, and reinforcing mode is reliable, and method is simple; The destruction to former girder construction concrete and reinforcing bar can be avoided simultaneously as far as possible, ensure that it is stablized, have broad application prospects.
Accompanying drawing explanation
Fig. 1 is the syndeton schematic diagram of the utility model forming concrete beam and newly-increased concrete beam;
Fig. 2 is the section structure schematic diagram of forming concrete beam in the utility model.
In figure: 1-is forming concrete beam, 2-reinforcing bar A, 3-increases concrete beam newly, 4-reinforcing bar B, 5-bolt.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, the syndeton of a kind of beam of forming concrete described in the utility model and newly-increased concrete beam, comprise forming concrete beam 1 and newly-increased concrete beam 3, reinforcing bar A2 is provided with in the described beam of forming concrete 1, post-installing rebar B4 in described newly-increased mixed earth beam 3, described reinforcing bar B4 is fixed in forming concrete beam 1 by bolt 5, makes increasing concrete beam 3 and forming concrete beam 1 form an overall structure.Adopt the technical program, making the anchoring degree of newly-increased concrete beam 3 steel bar stress meet code requirement, can better be connected with becoming ellbeam 1 structure, ensure the stressed according calculation model of binding site; Reduce the destruction to original girder construction as possible, ensure that it is stablized.Make the construction newly increasing concrete beam 3 more simple, convenient simultaneously, be conducive to engineering construction progress, ensure construction quality.
Reinforcing bar B4 in described newly-increased concrete beam 3 is planted and is fixed by bolt 5 through after forming concrete beam 1.
Reinforcing bar A2 in the described beam of forming concrete 1 is connected in length and breadth and is arranged in forming concrete beam 1.As shown in Figure 2, reinforcing bar A2 comprises the steel hoop that section is rectangle, and is connected with longitudinal reinforcement on four angles of steel hoop.
The described beam of forming concrete 1 arranges employing dabbing with the connecting surface of newly-increased concrete beam 3.
As shown in Figure 1, the utility model, when implementing, mainly carries out in accordance with the following steps:
The first step, in the boring of the position of newly-increased concrete beam 3 structure of forming concrete beam 1, boring is arranged and is determined according to the layout of main stress reinforcing bar;
Second step, reinforcing bar B4 implants forming concrete beam 1 side need be processed into the pattern that can be connected with bolt 5;
3rd step, is implanted into reinforcing bar B4 in the hole that the first step is bored;
4th step, to be fixed on reinforcing bar B4 on forming concrete beam 1 with bolt 5 after above-mentioned steps completes.
