Abstract
The invention overcomes the disadvantages that the existing light tensile lycra is not easy to be disassembled and can not adapt to different work conditions, provides a light tensile lycra which features fast assembly and disassembly, convenient use and various beam-type balance and basically does not take up storage space, and is characterized by comprising a fixed cross beam fixed on a bridge deck, a movable beam connected with the fixed crossbeam and a support frame used for supporting the movable crossbeam; the two ends of the fixed crossbeam are both provided with a fixed mechanism fixed on the bridge deck; one end of the movable crossbeam is connected with the fixed crossbeam and the other end is provided with a suspension mechanism. The invention has the following beneficial effects: (1) by adopting assembled mode, the tensile lycra can be conveniently assembled and disassembled in no need of use of a door hanger, so that electric energy is not consumed; and (2) as the whole equipment is fixed on the bridge, so that the construction requirement on the environment is low.
Description
Technical field
The present invention relates to a light tensile lycra, in particular, relate in particular to dismountable light tensile lycra that the prestressed stretch-draw operation is used in a kind of Prestressed T type bridge manufacturing process.
Background technology
As the indispensable frock of prestressed stretch-draw operation, the effect that supported and suspended jack carries out the stretch-draw operation is erected in stretch-draw, and previously used stretch-draw frame mainly is divided into two kinds: a kind ofly be; Adopt angle steel to be welded into the stretch-draw frame of whole rectangle frustum, high nearly 3.5 meters, take up an area of about 1.5 squares; And each use all need be used the gantry crane handling, even lower leg installs travelling wheel additional, but because deadweight is bigger; Artificial mobile difficulty is bigger, and the out-of-flatness of Liang Chang production area, can't artificially smoothly move; Can only pass through the gantry crane handling, take gantry crane service time; And there is the discrepancy in elevation on platform position limit mouth and road surface, need add chock during use, and operating efficiency is lower; Another kind is, adopts the stretch-draw frame of inequilateral supporting leg, and two supporting legs of an end on the ground; Two supporting legs of one end are on beam, and middle with the connection of round steel type crossbeam, the jack that plays carries out the stretch-draw operation; Use more convenient, but can't compatible little span bridge, and when not using because supporting leg is not isometric; Need keep flat, occupied ground is bigger, and is prone to bumped curved scrapping by frocks such as templates.
Summary of the invention
The present invention has overcome the shortcoming of above-mentioned technical problem, provide a kind of peace tear open quick, easy to use, various beam type take into account and do not take basically parking space light tensile lycra.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme:
Light tensile lycra of the present invention, its special feature is: include one and be used for fixing the bracing frame that moving beam and that the fixed cross beam, on bridge deck is connected with fixed cross beam is used to support moving beam; Described fixed cross beam two ends are provided with the fixed mechanism that is used for fixing on bridge deck, and an end of the described moving beam other end that is connected with fixed cross beam is provided with a hitch.
Light tensile lycra of the present invention, include one with moving beam on the Chain block that is connected of hitch, adopt suspension one to pull cucurbit and can adjust to operating position arbitrarily to the jack on the Chain block, save time, improved operating efficiency.
Light tensile lycra of the present invention; Said fixed cross beam and moving beam through a screw rod, be arranged on the fixed cross beam nut at fixed cross beam middle part and together the locking nut of locking effect be connected; Adopt the connected mode of nut and screw rod, make convenient disassembly and can reach requirement of strength.
Light tensile lycra of the present invention, support frame as described above are the tripod that a top and moving beam match, and tripod has good stable property.
Light tensile lycra of the present invention, the hitch on the said moving beam are a suspension sheave.
Light tensile lycra of the present invention, the fixed mechanism at said fixed cross beam two ends are a shackle and a L shaped fixed bar.
The invention has the beneficial effects as follows: (1) because this stretch-draw frame adopts the form of assembling, stretch-draw frame peace is torn open conveniently, need not to use gantry crane, not consumed power; (2) be fixed on the bridge owing to entire equipment, low to the environmental requirement of construction.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 fixed cross beam, 2 moving beams, 3 bracing frames, 4 screw rods, 5 suspension sheaves, 6 Chain blocks, 7 shackles, 8L shape fixed bar, 9 locking nuts, 10 fixed cross beam nuts.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1; Shown fixed cross beam 1 is the channel-section steel material with moving beam 2, is provided with the shackle of fixing with bridge 7 at the two ends of fixed cross beam 1 and is connected with the T-steel of L shaped fixed mount 8, one ends with retaining quarrel wall; One end and inboard are executed the seam crossing reserved steel bar and are fixed; Welding one fixed cross beam nut 10 is fixed on this fixed cross beam nut 10 through a screw rod 4 then in the middle of fixed cross beam 1, and this screw rod passes the circular hole of moving beam 2 one ends and locks with locking nut 9; Moving beam 2 is placed on the bracing frame 3; Should notice that when placing bracing frame 3 end away from fixed cross beam 1 should be high; Can guarantee to pull out jack like this, install frock such as work ground tackle after, as long as operating personnel exert all one's effort a little; Just can make jack slide to the operating position, reduce labor intensity of operating personnel with self gravitation.The other end of moving beam 2 hangs a suspension sheave 5, and the below of shown suspension sheave 5 is connected with one and is used to hang the Chain block 6 that rises jack.
Operating principle of the present invention is: after T type beam concrete strength reaches stretch-draw intensity; Operating personnel move on to each parts of stretch-draw frame on the T type beam bridge panel, and at first fixedly fixed cross beam 1, and this crossbeam one end is connected with the T-steel of retaining quarrel wall; One end and inboard are executed the seam crossing reserved steel bar and are fixed; The screw rod 4 of on the fixed cross beam nut 10 at fixed cross beam 1 middle part, screwing, and pass the screw on the moving beam to screw rod 4, lock with locking nut 9 then; Above the beam-ends longitudinal holes, place supporting bracket, be placed into moving beam 2 on the bracing frame 3, suspension sheave is placed in the channel-section steel gap of workspace of moving beam 2, and the stretch-draw frame promptly installs.Operating personnel can hang up Chain block 6 below suspension sheave, draw high jack and carry out the stretch-draw operation.
