Abstract
The utility model discloses a plate and beam reserved joint bar structure of a hydropower house, which comprises an earlier pouring concrete wall (1), a later pouring beam (2) and a later pouring plate (3), wherein a beam joint bar groove (4) and a plate joint bar groove (5) are formed in the earlier pouring concrete wall (1), and joint bars that are anchored into the earlier pouring concrete wall (1) and poured with the later pouring beam (2) and the later pouring plate (3) integrally are arranged in the beam joint bar groove (4) and the plate joint bar groove (5) respectively. According to the structure, the joint bars are connected with the wall, the plate and the beam that are poured by stages, so that the structure is high in integrity; wall construction gap positions are moved into the wall by the joint bar grooves, so that the construction gap positions are optimized, and the reliability of the structure is improved; the top surfaces of the joint bar grooves are in an expanded fracture surface state from inside out, so later pouring concrete can be densified conveniently; a dismounting-free formwork serves as a shaping formwork of the joint bar grooves, the difficulty that the formwork cannot be mounted or dismounted easily due to the fact that the joint bars penetrate through the formwork is overcome; and chiseling treatment on earlier pouring wall surfaces of the joint bar grooves is omitted.
Description
Technical field
The utility model relates to a kind of powerhouse of hydropower station plate-girder reserved joint bar structure, belongs to the concrete construction technical field.
Background technology
Powerhouse of hydropower station all needs to build reinforced concrete wall (wall under water) dash, gear soil in following position, ground below flood level or outside factory, with safety and the normal operation that guarantees factory building.Wall is important flood control and side direction retaining structure under water, is again the vertical supporting member of factory building inner panel girder construction simultaneously.In powerhouse of hydropower station concrete pouring construction process, flood control is passed the flood period or the needs of construction speed in order to satisfy, and generally builds in advance wall under water, after-pouring inner panel girder construction, therefore, how reliably to connect the body of wall of substage construction and slab and girder and just become an important problem.The general body of wall that adopts is connected by freely-supported with the plate-girder disengagement at present, perhaps reserves the plate-girder joint bar in body of wall, and body of wall is connected by vertical construction joints with the plate-girder bonding surface.But the freely-supported connection can not utilize body of wall to the fixed end effect of contraction of slab and girder, and structural integrity is poor, is unfavorable for antidetonation, can increase simultaneously the mid span moment of slab and girder, and material can not take full advantage of.And in " joint bar+vertical construction joints " connection, constuction joint is retained in body of wall and plate-girder bonding surface, this place's shearing is maximum, do not satisfy the principle (keeping somewhere the position unreasonable) of " constuction joint should be arranged on structure and be subjected to the shearing smaller part ", the plate-girder joint bar will pass wall form and cause damaged template and construction inconvenience, constuction joint seam face Disposal quality is wayward, New-old concrete joint surface easily forms plane of weakness, affects reliability of structure.Therefore, the technical scheme of the body of wall of existing connection substage construction and slab and girder or undesirable.
Summary of the invention
The purpose of this utility model is, a kind of body of wall for the connection substage construction and the powerhouse of hydropower station plate-girder reserved joint bar structure of slab and girder are provided, this structural integrity is strong, connection is reliable, and this structure can utilize body of wall to the fixed end effect of contraction of plate-girder, can overcome again existing constuction joint and keep somewhere the deficiencies in the prior art such as the position is unreasonable.
For realizing the purpose of this utility model, a kind of powerhouse of hydropower station plate-girder reserved joint bar structure of the present utility model, comprise first pouring concrete body of wall, after water Liang Hehou and water plate, wherein, beam joint bar groove and plate joint bar groove are set on described first pouring concrete body of wall, be respectively equipped with in beam joint bar groove and plate joint bar groove anchor in described first pouring concrete body of wall and with described after water Liang Hehou and water plate and build and become whole joint bar structure.
Further, beam joint bar groove and plate joint bar groove end face from inside to outside are the expansion section
Further, be provided with between described beam joint bar groove and plate joint bar groove and described first pouring concrete body of wall for form the non-dismantling formwork of beam joint bar groove and plate joint bar groove when building first pouring concrete body of wall.
Further, described joint bar comprises beam reserved joint bar and plate reserved joint bar.The beam reserved joint bar is provided with the beam joint bar that is no less than three roads and locates stirrup.
Compared with prior art, the utility model adopts joint bar to connect body of wall and the plate-girder of substage construction, and structural integrity is strong.By the joint bar groove, wall constuction joint position is moved on to body of wall inside, optimized the constuction joint position, stressed more reasonable, improved reliability of structure.Joint bar groove end face from inside to outside is the expansion section, is beneficial to rear pouring concrete and builds closely knit.Adopt non-dismantling formwork both to solve " joint bar is worn mould " as the typified form of joint bar groove, cause the difficulty of template installing/dismounting, save again the dabbing processing of the joint bar groove first being watered metope.Therefore, the utility model reached that globality is strong, simple in structure, easy construction, the reliable purpose of connection.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
A kind of powerhouse of hydropower station plate-girder reserved joint bar structure of the present utility model, as Fig. 1, Fig. 2 and shown in Figure 3, beam joint bar groove 4 and plate joint bar groove 5 formerly are set on pouring concrete body of wall 1, beam joint bar groove 4 and plate joint bar groove 5 embeds and forms the groove shape in first pouring concrete bodies of wall 1, with this, constuction joint between plate-girder and body of wall moved to body of wall inside.Be respectively equipped with in beam joint bar groove 4 and plate joint bar groove 5 from after water beam 2 and after water plate 3 anchor into first pouring concrete body of wall 1 and with after water beam 2 and after water plate 3 and build and become whole joint bar, and be provided with the non-dismantling formwork 6 for formation beam joint bar groove 4 and plate joint bar groove 5 when building first pouring concrete body of wall 1 between beam joint bar groove 4 and plate joint bar groove 5 and first pouring concrete body of wall 1.Joint bar comprises beam reserved joint bar 7 and plate reserved joint bar 9, and beam reserved joint bar 7 is provided with the beam joint bar and locates stirrup 8.
