Description
Technical field
The invention belongs to the device and methods of bridge construction, more particularly, to a kind of precast bridge concrete slab
Template and its application method.
Background technique
During the Prefabrication of bridge hollow board, need that pre-buried hinge is stitched reinforcing bar from sky in time after cored slab forming
The two sides of core are stretched out, but in the actual production process, due to the influence of human negligence either concrete curing age, often
Concrete on pre-buried hinge seam reinforcing bar cannot be cut completely completely, or during cutting the surface concrete on hinge seam reinforcing bar
The structure for destroying cored slab reduces the quality of cored slab, increases construction cost.
Summary of the invention
The purpose of the present invention is to propose to the template and its application method of a kind of precast bridge concrete core slab, not only structure
Rationally, easy to operate, it is safe and reliable, and concrete this process cut on hinge seam rebar surface is saved, it improves empty
The quality of core reduces construction cost.
Purpose of the invention is achieved like this: a kind of template of precast bridge concrete core slab is (referred to as hollow
The template of plate), including hinge seam reinforcing bar and template main panel, frame and cross reinforcing plate, the main panel it is transversal
Face is in two-fold bending, and (see Fig. 1), i.e. the top of the main panel is upper facade plate, middle part is skewback, lower part is lower facade
Plate, upper facade plate and the lower facade plate of the main panel are parallel to each other, and the main panel is used and is made with a thickness of the steel plate of 4mm,
Frame is set in the main panel surrounding, the intersection (folding of lower facade plate and skewback is located on the main panel
Crook) setting cross reinforcing plate, the frame, cross reinforcing plate be all made of channel steel and be welded, it is characterized in that: this one
The template of kind precast bridge concrete core slab further includes vertical strengthening ribs plate, through-hole, secondary template, upper link, lower link, extension
Hook, chaining, hinge and buckle are uniformly positioned apart from vertical strengthening ribs plate from left to right on the main panel, and this is perpendicular
It is to arrange that the vertical strengthening ribs plate available slot steel is made according to the design position of hinge seam reinforcing bar to stiffener plate, respectively two-by-two
It is corresponding on the main panel between adjacent vertical strengthening ribs plate to be located at upper facade plate and skewback intersection respectively symmetrically
Ground opens up the two square through-holes (opening up left through-hole and right through-hole) in left and right, and the width (or height) of the through-hole is greater than
The diameter of hinge seam reinforcing bar, center between the left through-hole and right through-hole is away from the design centre with adjacent hinge seam reinforcing bar two-by-two
Spacing is consistent, respectively two-by-two on the center of the upper end of the upper facade plate between adjacent vertical strengthening ribs plate
Upper link is fixedly installed respectively, respectively the top of the upper facade plate between adjacent vertical strengthening ribs plate is right respectively two-by-two
Two hinges in left and right should be fixedly installed, which can be for high-intensitive hinge, the hinged rectangle on the hinge of left and right two
Secondary template opens up break slot in the lower end of the secondary template, makes the position phase of the position of each break slot with each hinge seam reinforcing bar
Corresponding consistent, to allow hinge seam reinforcing bar to pass through, which is made of the steel plate of 4mm, under the secondary template
Lower link is fixedly installed on the center in portion, the chaining with hook is set between the upper link and lower link, meanwhile,
In the respectively corresponding left and right for being located at secondary template on the lower end of the upper facade plate between adjacent vertical strengthening ribs plate two-by-two
Revolving buckle is respectively set in two sides position.
A kind of application method of the template of precast bridge concrete core slab, it is characterized in that: will be pre- before casting concrete
The hinge seam reinforcing bar buried is just installed in place, and needs to cut the concrete of hinge seam rebar surface after eliminating prefabricated concrete hollow slab forming
This process is using step:
One) template of cored slab, is made:
It is designed according to a kind of structure of above-mentioned hollow plate shuttering, is uniformly positioned apart from vertical strengthening ribs on the home panel
Plate uniformly opens up through-hole on the upper facade plate of main panel, and the position of each through-hole is made to stitch the position of reinforcing bar corresponding one with each hinge
It causes, hinge is installed on the upper facade plate of main panel with the secondary template of hinge strip break slot, makes the position of each break slot and each hinge
The position for stitching reinforcing bar is corresponding to the same, installs link on upper facade plate, link under installing in secondary template, in upper facade plate
Corresponding chaining and revolving buckle of the installation with hook between secondary template；
Two) it, installs, use the template of cored slab:
The hook first passed through on chaining hangs up secondary template, and the hinge being connected with cored slab bottom plate main reinforcement is then stitched reinforcing bar
Correspondence is mounted in each through-hole opened up, then, is plucked hook, is kept secondary template sagging and level naturally, makes the secondary template
The break slot of lower end align with through-hole, twist buckle, by the main panel of secondary template and template against fixation, can pour
Concrete eliminates the concrete cut on hinge seam rebar surface, improves the quality of cored slab, reduce construction cost.
The template and its application method of a kind of precast bridge concrete core slab proposed by the invention, not only structure is closed
Reason, it is easy to operate, it is safe and reliable, and concrete this process cut on hinge seam rebar surface is eliminated, it improves
The quality of cored slab, reduces construction cost.
