Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
From a kind of structural representation of concrete slab of the bottom with conduit of Fig. 1 and Fig. 2 present invention, the present invention
Including polylith concrete bridge deck plate segment 1, it is glued by epoxy resin between concrete bridge deck plate segment 1；Wherein, concrete bridge
The manufacture method of panel section 1 is mainly in factory using matching precasting process production, i.e., first pour starting in precast pedestal
Sections, after on the basis of fixing end mould, and initial sections is pushed into into matched position, adjust plan-position and absolute altitude as matching
Sections, by Pin next sections is poured.During cast, sections both sides to be poured set relatively-stationary side form (only lateral folding and do not move
It is dynamic), front end sets fixing end mould, and rear end is then the front end face of the previous sections (matching beam) for having poured, and to be formed between the two
Matching seam guaranteeing the splicing precision of adjacent segment.Its concrete step includes：(1) model sheetinstallat, including fixing end mould,
Removable bed die, side form etc., wherein bed die consider the shaping of the reserved groove of floorings lower edge；(2) reinforcing bar is in the case where processing factory is accurate
After material, transport on reinforcing bar colligation placenta, artificial colligation shaping, by straddle truck Integral lifting to prefabricated bed die；(3) install pre-
Stress pipeline, floorings stock inlet and grout outlet built-in pipe；(4) concreting is carried out using suspension bucket mode, after the initial set of surface
Carry out wharf's pavement quality；Using sprinkling constant temperature, the maintenance of moisturizing state；(5) mounting hanger, using gantry crane lifting to area is repaired, enters
The reserved groove roughening of row is processed；(6) it is identified, is finally hung to and stores up area and carry out subregion storage.
The bottom of concrete bridge deck plate segment 1 is provided with multiple conduits 2 for forming self-locking steel reinforced concrete connector, conduit 2
For the reserved groove that surface is processed through roughening, the method that wherein conduit interface roughnessization is processed is including brushing medicament, hydraulic giant
Rinse dabbing, sandblasting etc..The main way of two of which is：(1) surface retarders+giant is rinsed：In reserved groove-bottom
Surface retarders are applied on mould, when concrete strength reaches the 30% of design strength, reserved groove bed die is removed, in time with height
Blow wash cement mortar, makes surface expose stone, reaches dabbing effect.(2) reserve groove bed die and adopt special roughening template,
Including template and net, net is detachably secured to template surface, and net is identical with the surface size of template, grid
Geometry forms the indent geometry of closure on the surface at reserved conduit interface.It is provided with concrete bridge deck plate segment 1
The slurry mouth 3 connected with conduit 2, slurry mouth 3 includes stock inlet 3a and grout outlet 3b；As concrete slab starting sections or
Stock inlet 3a is provided with concrete bridge deck plate segment 1 on last sections, on remaining sections of concrete slab
Grout outlet 3b is provided with, as shown in Figure 3.In order to improve the stability and security of concrete slab of the present invention, concrete bridge
Multiple shearing key teeths 4 are provided between panel section 1.
From Fig. 4 and Fig. 5, the present invention in the bottom of concrete slab by arranging what surface was processed through roughening
Conduit, and it is (prefabricated to be installed on the girder steel with decorative pattern perforate floor and rubber seal strip being formed the grouting channel of a sealing
Floorings should completely be compressed rubber strip using own wt, to ensure the sealing of grouting channel), by noting to grouting channel
Enter special high-strength grout so as to realize a kind of efficient assembled steel reinforced concrete combination beam, the efficient assembled steel reinforced concrete combination beam is due to it
Concrete slab is fabricated by using the present invention, thus efficiently solves the steel reinforced concrete knot that concrete and steel beam surface contact are caused
The problems such as conjunction face burn into concrete cracking, simultaneously effective ensure that construction quality and improve live work efficiency.According to Fig. 6 institutes
The self-locking steel reinforced concrete connector operation principle schematic diagram shown understands that this connector includes the decorative pattern perforated rib above steel beam flange plate
Conduit, high-strength grout, rubber seal strip that plate, floorings lower section are processed through interface roughnessization, the high-strength encapsulating material 7 is a kind of
Early strong (1d>35MPa), good fluidity (divergence>550mm), compression strength height (28d>The dry-mixed material of cement base 80MPa).
Different from traditional connectors, the self-lock connecting piece is reserved viscous between groove and steel plate interface by high-strength grout and floorings
Tie, rub to meet the stress demand such as longitudinal shear resistance and vertical drawing.Under longitudinal shear τ effects, there is sliding s at steel reinforced concrete interface
The protuberance that is necessarily accompanied with simultaneously between different materials of trend separate u, and this separations u is limited by floorings laterally pre- answering
Direct stress σ produced by power, separation trend is bigger, and direct stress is also bigger.From for the mechanism of action, also efficiently quickly connect this
The form of connecing is referred to as self-lock connecting piece.
It should be appreciated that having carried out exemplary description to the present invention above in conjunction with accompanying drawing, it is clear that the present invention is specific
Realization is not subject to the restrictions described above, as long as employing the various improvement that method of the present invention design and technical scheme are carried out,
Or it is not improved by the present invention design and technical scheme directly apply to other occasions, in protection scope of the present invention
It is interior.
