Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the utility model embodiment and accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.It should be noted that, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Refer to Fig. 1 and Fig. 2, the utility model specifically discloses working platform in a kind of bridge pier rapid construction, comprise the unit module of at least one vertical pile, each unit module comprises steel structure framework 1, fixed platform 4, movable skeleton 3, movable platform 5, stair 2 and guard rail; Steel structure framework 1 adopts shaped steel to be welded, the steel structure framework 1 of each unit module is set to double-layer structure, the top of steel structure framework 1 and bottom respectively correspondence are provided with fixing hole, and the steel structure framework 1 of the unit module that adjacent two layers stacks is connected through fixing hole by latch 6 or bolt; Fixed platform 4 is laid on every Rotating fields of steel structure framework 1; Movable skeleton 3 is movably connected on the both sides of steel structure framework 1 by latch 6, and the both sides of every Rotating fields are all connected with a movable skeleton 3; Movable platform 5 is laid on movable skeleton 3; Stair 2 are connected with between the double-layer structure of steel structure framework 1; Guard rail is provided with around stair 2.
Be flexibly connected between movable skeleton 3 with fixing skeleton, allow to receive movable skeleton 3.Operating personnel carries out needing when constructing to stand in fixed platform 4 and movable platform 5.Fixing skeleton and movable skeleton 3 are all carry out welding production by shaped steel such as angle steel, channel-section steel, i iron beyond job location, preferably prefabricated in the place that the environment such as factory are comparatively superior, then the job location being transported to outfield is to be installed.Only to need in job location by loop wheel machine, unit module vertical pile to be connected and fixed by latch 6 or bolt, a complete interior working platform can be assembled.Similarly, after construction is complete, interior working platform can successively carry out dismantling and reclaiming, and waits until next construction usage.
Different from general scaffold, interior working platform is without the need to carrying out loaded down with trivial details and attached dangerously to build at every turn, and interior working platform can provide and stablizes broad plane of standing, and construction operation difficulty is reduced greatly, also effectively can improve construction quality.Every Rotating fields is equipped with stair 2 convenient working personnel and moves between different aspects, and guard rail then shields to operating personnel, the personal safety of effective guarantee operating personnel.
As preferably, described fixed platform 4 or movable platform 5 are plank or steel plate.The Main Function of fixed platform 4 and movable platform 5 is for operating personnel provides plane of standing, and is ensureing the plank or steel plate that preferably adopt lightweight under well-set prerequisite.
As preferably, every Rotating fields of described steel structure framework 1 is high 1.8 meters-2 meters.This highly meets the height of general job personnel, ensures again to save most space simultaneously, reduces and manufactures and cost of transportation.Meanwhile, ensure operating personnel can freely movable while reduce floor height as far as possible and help the convenience ensureing and construct, there will not be the region that to there is operating personnel between double-layer structure and cannot touch.
As preferably, the bottom being positioned at the steel structure framework 1 of bottom is fixed on concrete surface by expansion bolt.Apparently, the stability being positioned at the steel structure framework 1 of bottom is vital, has material impact to the stability of the steel structure framework 1 being positioned at upper strata.Firm in order to ensure the integral installation of interior working platform, need the steel structure framework 1 of external force to bottom by expansion bolt to be fixed, the steel structure framework 1 of bottom is taken root.
As preferably, described movable skeleton 3 is rectangular, trapezoidal or semicircle.Semicircular movable skeleton 3 is especially applicable to round ended pier, and its profile with round ended pier is the most identical, and the entire area of the movable platform 5 caused also is maximum, and thus most convenient operating personnel constructs.Trapezoidal and movable skeleton 3 that is rectangle is convenient to manufacture most.The type selecting of movable skeleton 3 should be chosen according to physical condition.
Working platform in a kind of bridge pier rapid construction that the utility model provides, replaces scaffold with working platform, significantly improves efficiency of construction and construction quality.Interior working platform can provide better working environment, ensure that the personal security of work high above the ground preferably, the comfortableness of effective raising working environment, carries out by interior working platform the labour intensity that bridge pier rapid construction effectively can reduce operating personnel, ensures the stability of bridge pier reinforcing bar.Interior ramp moduleization design, install simple, reduce the mounting or dismounting cycle, stability is high.In adopting, working platform carries out the input that Bridge Pier Construction can reduce labour, plant equipment, template etc., saves construction cost.
The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
