Abstract
The invention discloses an assembled stairway and the construction technology and relates to the technical field of bridge pier construction. The stairway comprises single stairway units and a concrete foundation. The concrete foundation is provided with a plurality of stairway units. One stairway unit comprises four posts, transverse rods, oblique rods, a stairway body and inserting pins. The transverse rods are welded among the four posts, the oblique rods are arranged among the transverse rod in a crossed manner and among the posts, the stairway body is arranged on the bidiagonal transverse rods inside the posts, safety nets are arranged outside the posts, and the stairway units are connected through pin holes and the inserting pins; when the assembled stairway units is longer than 4m, a horizontal reinforcing frame is fixed to the outside of the posts. The upper and lower walking stairway units are assembled in a segmented manner, so that periodical usage is implemented, and cost is reduced; the assembling technology is simple, assembly can be implemented through a tower crane manually, manual operation is reduced, and safety risks are reduced.
Description
Technical field
The present invention relates to Bridge High-pier technical field of construction, be specifically related to a kind of pin-connected panel ladder access and construction technology.
Background technology
Before Bridge High-pier construction, tower crane all to be installed, all generally to adopt to set up by support, be greater than 30 meters of pier studs and set up outrigger, set up internal frame as reinforcing bar binding support, when template installation and removal, rely on Hanging Basket as operation platform, personnel adopt up and down gate-type falling bodies or humanoid ladder access upper and lower, template assembly adopts 50t assembling hoist, requires Land leveling, and ground is firm, and add sleeper, can adopt if desired hardening of concrete.
Above-mentioned traditional Bridge High-pier construction ladder access is set up more difficult, wastes time and energy, and has increased manual operation, also have certain potential safety hazard, and cost of production is higher.
Summary of the invention
Because the above-mentioned defect of prior art the invention provides a kind of deck-molding pier personnel's upper and lower merogenesis pin-connected panel ladder access of bridge and construction method.
For achieving the above object, the invention provides a kind of pin-connected panel ladder access and construction technology, comprise ladder access single-unit monomer, concrete foundation, in concrete foundation, be provided with multiple monomers, described ladder access single-unit monomer comprises column, cross bar, brace, ladder access and latch, between four root posts, be welded with cross bar, arranged in a crossed manner between cross bar have a brace, and between column, be also provided with brace, on the diagonal angle cross bar of column inside, be provided with ladder access, four root post outer setting have safety net, and each ladder access single-unit monomer connects by pin-and-hole and latch; When the ladder access single-unit monomer of described splicing exceedes 4 meters, column external stability has horizontal reinforcing frame.
As preferably, described ladder access width must not be less than 0.9m, and the gradient must not be greater than 1: 1, and sections is not higher than 2.5m.
The present invention first installs tower crane before high pier construction, first does ladder access basis on pier side, can make of coagulation.Then with tower crane merogenesis lifting ladder access sections, artificial cooperation.
Beneficial effect of the present invention: upper and lower People's Bank of China ladder access is made to merogenesis pin-connected panel, can have enough to meet the need like this use and reduce costs.Assembling process is simple, only needs tower crane and artificial cooperation assembled.Reduce manual operation, reduce potential safety hazard.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structure for amplifying schematic diagram of ladder access single-unit monomer of the present invention.
Detailed description of the invention
With reference to Fig. 1-2, this detailed description of the invention is by the following technical solutions: a kind of pin-connected panel ladder access and construction technology, comprise ladder access single-unit monomer 1, concrete foundation 2, in concrete foundation 2, be provided with multiple monomers 1, described ladder access single-unit monomer 1 comprises column 11, cross bar 12, brace 13, ladder access 14 and latch 15, between four root posts 11, be welded with cross bar 12, arranged in a crossed manner between cross bar 12 have a brace 13, and between column 11, be also provided with brace 13, on the diagonal angle cross bar of column 11 inside, be provided with ladder access 14, four root post 11 outer setting have safety net, each ladder access single-unit monomer 1 connects by pin-and-hole and latch 15, when the ladder access single-unit monomer 1 of described splicing exceedes 4 meters, column 11 external stabilities have horizontal reinforcing frame 3.
It should be noted that described ladder access 14 width must not be less than 0.9m, the gradient must not be greater than 1: 1, and sections is not higher than 2.5m.
A kind of pin-connected panel ladder access and construction technology described in this detailed description of the invention:
1, first do ladder access basis on pier side, can make of coagulation, the tower-body standard section of then slinging (ladder access single-unit monomer or lower tower body), starts slew gear, boom is rotated to the direction of introducing tower-body standard section.
2, in the guiding of tower-body standard section lower end to be introduced connects trepanning, insert four and introduce pulley, put on guide frame, and by the trailer wagon tower-body standard section of slinging, reach left and right, 10.5m amplitude place, substantially drop on oil cylinder center line with the center of gravity that keeps jacking part, adjust the gap (～2.5mm) of climbing support roller and standard knot, with entering to make slew gear in on-position.
3, whether the each mechanical position of detailed inspection connects correctly, checks electric part and hydraulic part, checks whether the bearing pin of oil cylinder crossbeam has inserted marking time in pin-and-hole of standard knot, be sure of on inspection errorless after, remake preparation jacking.
4, take the connecting bolt pair between undersetting and lower tower body apart, then drive oil pump, control crank, makes oil cylinder by superstructure jack-up, and the pawl of climbing of climbing support is bearing on the jacking support plate of tower body.
5, control crank, regains piston rod, and at this moment crossbeam rises in a jacking support plate, again climbs, and again stretches out after total length until piston, can introduce tower-body standard section.
6, tower-body standard section is aligned to lower tower body, control crank, puts down tower-body standard section slowly, after docking, extract out and introduce roller, the tower-body standard section of introduction and lower tower body are coupled together with bolt pair, and tighten, complete like this high workload that adds of a tower-body standard section.
7, the height that tower-body standard section increases often exceedes 4m should arrange the horizontal reinforcement (horizontal reinforcing frame 3) being connected with column together.
Upper and lower People's Bank of China ladder access is made merogenesis pin-connected panel by this detailed description of the invention, can have enough to meet the need like this to use to reduce costs.Assembling process is simple, only needs tower crane and artificial cooperation assembled.Reduce manual operation, reduce potential safety hazard.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work.Therefore, all technician in the art, all should be in by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
