Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
From the schematic diagram of a kind of bottom of the utility model shown in Fig. 1 to Fig. 4 with the new concrete bridge deck of conduit, the utility model comprises polylith concrete bridge deck plate segment 1, is gluedd joint between concrete bridge deck plate segment 1 by epoxy resin; Wherein, the manufacture method of concrete bridge deck plate segment 1 mainly adopts coupling precasting process to produce in factory, namely initial sections is first built at precast pedestal, after with fixed end mould for benchmark, and initial sections is pushed into matched position, adjust plan-position and absolute altitude as matching segment, build next sections by Pin.During cast, relatively-stationary side form (a side direction folding and do not move) is established in sections both sides to be poured, fixed end mould is established in front end, rear end is then the front end face of the last sections (matching beam) watered, and with the coupling seam formed between the two to guarantee the splicing precision of adjacent segment.Its concrete step comprises: (1) model sheetinstallat, comprises fixed end mould, removable bed die, side form etc., and wherein bed die considers that bridge deck lower edge reserves the shaping of groove; (2) reinforcing bar is after the accurate blanking of processing factory, and be transported on reinforcing bar binding placenta, artificial colligation is shaping, by straddle truck Integral lifting to prefabricated bed die; (3) prestressed pipeline, bridge deck stock inlet and grout outlet built-in pipe; (4) adopt suspension bucket mode to carry out concreting, after surperficial initial set, carry out wharf's pavement quality; Adopt and spray constant temperature, the maintenance of moisturizing state; (5) mounting hanger, utilizes gantry crane lifting to repairing district, carries out the process of reserved groove roughening; (6) identify, finally winch to and store up district and carry out subregion and deposit.
The bottom of concrete bridge deck plate segment 1 is provided with multiple conduit 2 for the formation of Novel self-lock steel reinforced concrete connector, conduit 2 is the reserved groove of surface through roughening process, and the method for wherein conduit interface roughness process comprises brushing medicament, hydraulic giant rinses dabbing, sandblasting etc.Wherein two kinds of main ways are: (1) surface retarders+giant rinses: on reserved groove bed die, be coated with surface retarders, when concrete strength reaches 30% of design strength, remove reserved groove bed die, timely high pressure water washing cement paste, make surface expose stone, reach dabbing effect.(2) reserved groove bed die adopts special roughening template, comprise template and net, net is detachably fixed on template surface, and net is identical with the surface size of template, and the geometry of grid forms closed indent geometry on the surface at reserved conduit interface.Concrete bridge deck plate segment 1 is provided with the slurry mouth 3 be communicated with conduit 2, slurry mouth 3 comprises stock inlet 3a and grout outlet 3b; Be provided with stock inlet 3a as on the concrete bridge deck plate segment 1 on the initial sections of concrete slab or last sections, all the other sections of concrete slab be provided with grout outlet 3b, as shown in Figure 4.In order to improve stability and the safety of the utility model concrete slab, between concrete bridge deck plate segment 1, be provided with multiple shear connector tooth 4.
From Fig. 5 and Fig. 6, the utility model is by arranging the conduit of surface through roughening process in the bottom of concrete slab, and (prefabricated bridge utilizes own wt rubber strip should be compressed completely to be arranged on the grouting channel girder steel with decorative pattern perforate floor and rubber seal strip being formed a sealing, to ensure the sealing of grouting channel), by injecting special high-strength grout to grouting channel thus realizing a kind of new and effective assembling steel reinforced concrete compound beam, this new and effective assembling steel reinforced concrete compound beam adopts the utility model manufacture to form due to its concrete slab, thus effectively solve concrete and contact the steel reinforced concrete bonding surface corrosion caused with steel beam surface, the problems such as concrete cracking, effectively ensure that construction quality and improve on-the-spot work efficiency simultaneously.Novel self-lock steel reinforced concrete connector operating principle schematic diagram according to Fig. 7, this novel connector comprises conduit, high-strength grout, rubber seal strip through interface roughness process below decorative pattern perforate floor above steel beam flange plate, bridge deck, and this high-strength encapsulating material is that a kind of cement based of early strong (1d>35MPa), good fluidity (divergence >550mm), compressive strength high (28d>80MPa) is dry mixed material.Different from traditional connectors, this Novel self-lock connector relies on high-strength grout and bridge deck to reserve bonding between groove and steel plate interface, rub to meet longitudinal shear resistance and the vertical stressed demand such as drawing.Under longitudinal shear τ effect, steel reinforced concrete interface has the trend of slippage s simultaneously inevitable along with the protuberance separation u between different materials, and this separation u is limited by the normal stress σ that transverse prestress in bridge deck produces, and separation trend is larger, and normal stress is also larger.From the mechanism of action, also this efficient type of attachment is fast referred to as self-lock connecting piece.
Should be understood that; by reference to the accompanying drawings exemplary description is carried out to the utility model above; the concrete realization of obvious the utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasions, all in protection domain of the present utility model without to improve.
