In order to overcome the defects of the prior art, the invention provides the prefabricated construction platform and the construction method of the hollow arch bridge hanging beam bracket, which are used for constructing the hanging beam bracket, improve the safety of the construction process and are beneficial to improving the moisture efficiency.
The technical scheme adopted by the invention for solving the problems is as follows: the utility model provides a prefabricated formula construction platform of empty stomach arched bridge hanging beam support, includes that a plurality of sets up the back on the arch ring and plants the reinforcing bar and set up the assembled concrete cushion on the arch ring, the assembled concrete cushion on be provided with the through-hole that a plurality of can plant the reinforcing bar cooperation installation with the back.
Further, in order to better realize the invention, the upper surface of the assembled concrete cushion block is a horizontal plane, and the lower surface of the assembled concrete cushion block has the same profile as the upper surface of the arch ring.
Furthermore, in order to better realize the invention, the exposed length of the post-planted steel bar is greater than that of the through hole corresponding to the post-planted steel bar.
Further, in order to better realize the invention, the free end of the post-planting steel bar is provided with a nut.
A construction method of a hollow arch bridge hanging beam support comprises the steps of arranging a plurality of post-planted steel bars on an arch ring, prefabricating an assembly type concrete cushion block, reserving a plurality of through holes capable of being installed with the post-planted steel bars in a matched mode on the assembly type concrete cushion block, and enabling the through holes to be aligned with the post-planted steel bars for installation when the assembly type concrete cushion block is installed.
The beneficial effect that this scheme obtained is:
this scheme can be under construction a platform on the arch ring and hang the construction basis of roof beam support as the construction, avoids direct arc upper surface construction at the arch ring, is favorable to reducing the construction degree of difficulty, improves the efficiency of construction, reduces the construction risk, and the work of prefabricated assembled concrete cushion can go on in step with the work of construction arch ring to reduce latency, be favorable to improving the efficiency of construction, shorten construction cycle.
Drawings
FIG. 1 is a partial schematic view of a hollow arch bridge;
fig. 2 is a schematic structural diagram of the present solution.
Wherein: 1-post-planting reinforcing steel bars, 2-assembled concrete cushion blocks, 3-screw caps, 7-arch rings and 8-hanging beams.
Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited to these examples.
Example 1:
in this embodiment, a prefabricated formula construction platform of empty stomach arched bridge hanging beam support, include and plant reinforcing bar 1 and set up assembled concrete cushion 2 on arch ring 7 after 7 construction of arch ring set up on arch ring 7 after, assembled concrete cushion 2 is the prefab, makes rather than the synchronization at the in-process of 7 construction of arch ring, reserves the through-hole that a plurality of can install with planting reinforcing bar 1 cooperation after on assembled concrete cushion 2. After the post-planting steel bars 1 are constructed, the assembly type concrete cushion blocks 2 are hoisted to the positions above the post-planting steel bars 1, the through holes are aligned with the post-planting steel bars 1, and then the assembly type concrete cushion blocks 2 are put down to complete installation. The fabricated concrete cushion block 2 is used as a construction foundation construction hanging beam support, and a template for hanging beams 8 is arranged at the top of the hanging beam support for pouring concrete. According to needs, can set up a plurality of assembled concrete cushion 2 in order to satisfy the construction demand on the arch ring 7.
For the convenience of construction, the upper surface of the fabricated concrete cushion block 2 is designed into a horizontal plane, so that the stability of the beam hanging bracket is improved, and the construction difficulty of the beam hanging bracket is reduced. The lower surface of the fabricated concrete cushion block 2 is designed to be an arc surface having the same profile as the upper surface of the arch ring 7, so that the stability of the fabricated concrete cushion block 2 can be enhanced.
In this embodiment, the diameter of post-planting reinforcing bar 1 be 28mm, be provided with two rows, the row spacing is 300mm, each row is provided with four post-planting reinforcing bars 1 and the interval is 500 mm. The corresponding through holes are arranged in two rows, the row distance is 300mm, each row is provided with four through holes, the distance is 500mm, and the diameter of each through hole is larger than or equal to 28 mm.
In this embodiment, the diameter of the through hole is selected to be 30mm, so that the through hole is aligned with the post-planted steel bar 1.
After the construction of the hanging beam 8 is completed, the template and the hanging beam bracket for the hanging beam are dismantled, and the assembled concrete cushion block 2 can be lifted upwards and taken out for reuse, so that the material is saved, the construction cost is reduced, and the construction waste is reduced.
After the assembled concrete cushion block 2 is taken out, the post-planted steel bars 1 need to be taken out, the portions beyond the post-planted steel bars 1 can be cut off, the post-planted steel bars 1 can also be completely taken out, and the hole left by the post-planted arch ring 7 is taken out to be filled with filler for the steel-planting holes.
Example 2:
on the basis of the above embodiment, in this embodiment, the exposed length of the post-planted steel bar 1 is greater than the length of the through hole corresponding to the post-planted steel bar. The part of the post-planted steel bar 1 exceeding can be used as a connecting structure of the hanging beam support, so that the hanging beam support is convenient to construct, and the stability of the hanging beam support is improved.
The free end of post-planting reinforcing bar 1 install nut 3, post-planting reinforcing bar 1 chooses for use the reinforcing bar that takes the screw thread, utilizes nut 3 and post-planting reinforcing bar 1 cooperation to use, can lock assembled concrete cushion 2, avoid assembled concrete cushion 2 not hard up and influence superstructure's stability, be favorable to improving the security performance.
The foregoing is only a preferred embodiment of the present invention, and the present invention is not limited thereto in any way, and any simple modification, equivalent replacement and improvement made to the above embodiment within the spirit and principle of the present invention still fall within the protection scope of the present invention.
