Description
Technical field
The present invention relates to a kind of mould before the wet seam of bridge floor being built in two-wire tee girder sets up and install device.
Background technology
In the time setting up tee girder bridge, after two-wire tee girder has set up, on bridge floor, can form 3 wet seams, the in the situation that of normal line spacing, every wet seam generally has 30 centimetres wide, and more than 30 meter long, construction process requirement will carry out reinforced concrete to wet seam builds, to complete the civil engineering of bridge floor.Building before wet seam, to carry out formwork erection to wet seam, then just can carry out cement builds, existing formwork way is to adopt to hang modular form and punching to the structure of drawing, namely template adopts wooden form or bamboo offset plate, utilize No. 12 fining twisted steels as to pull bar, pull bar is through in pvc pipe, the stressed support as template of one steel pipe or a lumps of wood is set between two tee girders of bridge floor, by clamp nut, wooden form sling and be fastened on wet seam below, and every 3 meters, an auxiliary form removal hole is being set along bridge longitudinal direction, the diameter of this hole is 3 centimetres, pre-buried pvc pipe in the wet seam of precast, pull bar is passed from pvc pipe.Because bridge floor ancillary works is too much, comprise the wet seam of T beam bridge floor system, laterally connecting partition, gear quarrel wall, transverse stretching, slip casting, sealing off and covering anchorage, sidewalk angle bar frame is installed, sidewalk pedestrian andante is installed, cable channel is installed, the a lot of working procedures of shrinkage joint installation etc., on bridge floor, often there is the situation of cross-operation, particularly the heavy-duty vehicle such as Beam transportation vehicle passes through from bridge floor continually, often occur to be erected at the situation of hanging mould steel pipe or lumps of wood press-bending or compressive strain of the wet seam on bridge floor, cause formwork again, and form removal is met difficulty, need be by reserved form removal hole, down suppress the demoulding of template ability by instruments such as wooden sticks through reserving hole, meanwhile, reserved form removal hole is easily crammed, also affect engineering attractive in appearance.In addition, in the time of stripping, because wooden form self is heavier, volume is also large, is generally to adopt wooden form to be directly slowly put on level land by rope, then after picking up by workman, transports to the construction technology of bridge floor, exist workload large, the serious problem with affecting integral construction efficiency of damaged template.
Summary of the invention
The invention provides the wet seam erecting device of a kind of tee girder bridge deck, solved easily damaged, form removal is difficult and template recycling rate of waterused is low problem of erecting device that existing two-wire tee girder exists the formwork support process of the wet seam of bridge floor in setting up.
The present invention solves above technical problem by the following technical programs:
The wet seam erecting device of a kind of tee girder bridge deck, comprise left tee girder and right tee girder, between left tee girder and right tee girder, be provided with wet seam, the right-hand member head of the embedded bar of left tee girder is arranged in wet seam, the left end head of the embedded bar of right tee girder is arranged in wet seam, on thin steel form, be provided with two row's preformed holes, tail end at suspension hook is provided with screw thread, the tail end of suspension hook is screwed together with nut from preformed hole passes, the head crotch of the suspension hook passing from the preformed hole of left bank is articulated on the right-hand member head of embedded bar of left tee girder, the head crotch of the suspension hook passing from right row's preformed hole is articulated on the left end head of embedded bar of right tee girder.
In the every row's preformed hole arranging on thin steel form, the spacing between adjacent preformed hole equates.
A kind of wet seam formwork form removal method of tee girder bridge deck, comprises the following steps:
The first step, on the thin steel form of the rectangle of 3 millimeters thick, get out two row's preformed holes, the wet seam that thin steel form is formed between left tee girder and right tee girder, be delivered to wet seam below;
Second step, by the tail end of suspension hook from top to bottom the preformed hole from thin steel form through thin steel form, nut is screwed onto to the tail end of suspension hook;
The 3rd step, the head crotch of the suspension hook passing from the preformed hole of left bank is articulated on the right-hand member head of embedded bar of left tee girder, the head crotch of the suspension hook passing from right row's preformed hole is articulated on the left end head of embedded bar of right tee girder;
The 4th step, adjust respectively the nut that the afterbody of each suspension hook is spirally connected, make thin steel form parallel with T beam bridge floor and with two T beams go out eaves bottom joint close, complete formwork;
The 5th step, solidify and reach after technological requirement when the steel concrete being cast in wet seam, knock the nut being spirally connected on the bottom surface of thin steel form with iron hammer, make the tail break of suspension hook and come off, the thin steel form coming off is downwards delivered on bridge floor from other does not carry out the wet seam of formwork, during in order to next formwork, uses.
Erecting device of the present invention does not arrange any steel pipe or wood lump supporting support on bridge floor, the destruction of thoroughly having avoided bridge floor contact haulage vehicle to cause the spreading of erecting device; Template adopts thin steel form to be not easy distortion, and form removal is very easy to operation, workman only need rap hook nut and suspension hook exposed parts with tup below, and suspension hook exposed parts is just tear-away, utilizes a crowbar sled gently, punching block will come off, workman just can be delivered to template on bridge floor along beam seam, and used convenient especially next time, and template Reusability rate is high, improve efficiency of construction, guaranteed that the wet joint concrete of having built is smooth.
