Description
Technical field
Patent of the present invention belongs to concrete prefabricated element and makes field, and in particular to a kind of Precast Concrete Box Girder comb plate
Fixing device.
Background technology
With the propulsion of building industrialization, municipal component is greatly developed, and each production technology is also obtained in process of production
Update.
Current, most of Precast Concrete Box Girder all has that heart mould floats in process of production, with
A series of production problems that heart mould floating triggers, if surfacing steel bar floats will to cause to be taken off between comb plate and box girder formwork
From so that leak concrete between gap, the problems such as cause the waste of quality problems and material.
In original production technology, comb plate is positioned.First method is will to be welded by spot welding form between comb plate
In prefabricated case beam template, when prefabricated case beam form removal, comb plate is obtained first to be removed, if not firm being spot welded, then
It is easy to shake open solder joint when casting and compacting of concrete, causes concrete to be revealed, if welding firm in spot welding, but
Taken considerable time again removing during comb plate is obtained, or even cause comb plate to deform in demolishing process.Also when pre-
When box beam deck-siding processed changes, the solder joint that pad leaves needs polishing cleaning, so will also result in damage to prefabricated case beam template.
Second method is welded using reinforcing bar oblique, and of reinforcing bar is welded on the gusset of comb plate, a welding
In the solder joint that box girder formwork is cleared up in template by being polished in outermost template, when can so prevent deck-siding from changing.But
Also cause comb plate to deform because of pad jail excessively sometimes when removing comb plate, and can similarly be made in casting and compacting of concrete
Into the phenomenon that solder joint shakes out, concrete is caused to be revealed.
The content of the invention
For problems of the prior art, the present invention provides a kind of Precast Concrete Box Girder comb board fixer,
Comb plate can be fixed respectively horizontal and vertical, stability and reliability that enhancing comb plate is fixed are improved prefabricated
The quality of component.
To achieve the above object, the present invention uses following technical scheme：
A kind of Precast Concrete Box Girder comb board fixer, the fixing device includes comb plate body, stopping means, fixed dress
Put, box beam surfacing steel bar and box girder formwork,
The comb plate body is made up of comb plate panel and gusset, the transverse slat of the comb plate panel including L-shaped setting and
Riser, is welded with some gussets on transverse slat, the base of the gusset is fixed on transverse slat, a side of gusset be fixed on it is perpendicular
On plate, riser is provided with some U-type grooves, and the gusset and U-type groove are spaced apart, and at least two are fixed with the transverse slat
Fixed station, the fixed station is concordant with the upper surface of comb plate body, and fixing hole, box beam are equipped with described each fixed station
Press strip is pressed on the upper surface of comb plate body by fixing hole through after U-type groove colligation for surfacing steel bar, by fixing hole with
The corresponding through hole bolt opened up on press strip is fixed,
Fixing device is provided with stopping means, described fixing device one end is fastened on comb plate on another side of gusset
Body is fixed, the fixing device other end is fixed on box girder formwork by stopping means.
The press strip is horizontal T-shaped.
The stopping means includes substrate, spacing steel plate, round steel pad and wedge-shaped fastener, and the spacing steel plate is arranged on substrate
On, round steel pad is fixed on one end of substrate, and spacing hole is offered on the spacing steel plate, and two grooves are provided with the substrate
Mouthful, described two notches are symmetrically distributed in spacing steel plate both sides, substrate is fixedly connected with box girder formwork by notches.
The fixing device includes two height identical round steel and two block length identical channel-section steels, and two blocks of channel-section steels are welded respectively
The both sides of round steel are connected on, the accommodating chamber for placing spacing steel plate is formed between two round steel and two blocks of channel-section steels, the round steel
With diameter greater than the thickness of spacing steel plate.
The round steel pad is 12mm screw-thread steels, the folder between the upper surface of the substrate where round steel pad and the lower surface of channel-section steel
Angle α is 2 ~ 3 °.
The angle α is 2 °
Compared with prior art, beneficial effects of the present invention are：
1. press strip of the present invention and stopping means, the setting of fixing device so that box beam comb plate can be in horizontal and vertical difference
Comb plate is fixed, stability and reliability that enhancing comb plate is fixed improve the quality of prefabricated components；2. the present invention is round
After steel pad is installed, angle α is formed between the upper surface of the substrate where round steel pad and the lower surface of channel-section steel, the formation of the angle α
Can help fixing device that the power that a limitation comb plate is moved outward is formed when being contacted with comb plate, while to spacing
Device forms normal pressure and has reached the frictional force strengthened between stopping means and box girder formwork by round steel；3. angle α is 2 ~ 3 °,
Selection low-angle be in order to protect stopping means because when angle it is excessive if, the steel plate of stopping means must be lengthened, first,
Steel plate lengthens the inconvenience formed to construction, because can so hinder the construction of workman during installation positioning comb daughter board, also
The anti-floating depression bar for preventing heart mould from floating can be set during Construction of Precast Box Beam, and stopping means is long to may interfere with anti-floating
The distribution of depression bar；Secondly, stopping means is long in amechanical angle, and the torque for so being produced by reaction force also can be more
Greatly, the safe handling for stopping means produces influence；4. the problem for being run into the production process actual by combining scene, if
Meter works out technical scheme, and first, the controllable comb plate of beam changes and changes the present invention according to deck-siding, in this process
In need not be made with box girder formwork and be welded and fixed, so reduce the damage to box girder formwork；Secondly, in concrete vibrating mistake
Be not in the phenomenon of comb plate and box girder formwork disengagement in journey, cause concrete to be revealed；Finally, the circulation for improving comb plate makes
With number of times, the process of dismounting is to comb dash-board injury and deformation very little.In sum, the utilization of comb plate, not only ensure that case
The size quality of beam, and recycling for template is ensure that, so as to reduce production cost, improve operating efficiency；5. this hair
The bright phenomenon that can solve to cause concrete to be revealed by the drive of surfacing steel bar when prefabricated case beam heart mould floats, improves
The quality of prefabricated case beam, also improves mould installion efficiency.
