Description
Technical field
The utility model belongs to infrastructure field, and wet seam hole safeguard structure between a kind of Bridge Beam is provided especially.
Background technology
The construction of bridge prefabrication Method for Installation is near prefabricated factory or the bridge site at convenient transportation, precasting yard to be set to carry out the prefabricated work of beam, then adopts certain erection method to install.When the precast beam of prefabricated Method for Installation construction is manufactured, a set of mould bases can repeatedly have enough to meet the need use, and the beams and slabs quality of production is good; In bridge prefabrication Method for Installation work progress, top and the bottom structure can parallel operations, and the duration is short, can effectively utilize labour, has reduced construction costs; In precast beam erection process, do not need to arrange ground support, do not affect traffic under navigation and bridge, construction safety, reliable, have good construction environment, mechanization, automaticity are high, save labour, reduce labour intensity, the reduction of erection time, in highway, railway, municipal process, use extensively.In bridge prefabrication Method for Installation work progress, beam body sets up progress usually faster than bridge deck construction, and between beam, wet seaming position and part need the formation of reserved hogging moment stretch-draw hole place to face cavity mouthful.
The seam hole protection of wetting between traditional beam is often out in the cold, is not effectively covered, and to bridge deck, construction leaves potential safety hazard.If traditional approach directly adopts veneer to cover, veneer be easily moved and hole on veneer can not bear useful load, if adopt the sealing such as steel plate portal, cost is high, unfavorable construction is unrealistic.
Utility model content
The purpose of this utility model is to provide wet seam hole safeguard structure between a kind of Bridge Beam, can effectively address the above problem.
The technical solution of the utility model is: wet seam hole safeguard structure between a kind of Bridge Beam, be located on the prefabricated case beam/Precast T-Beam 2 with wet joint reserved steel bar 1, for 3 places, adjacent two prefabricated case beams/Precast T-Beam 2 wet seam hole are protected, comprise: backing plate 5 and overlay 6, described backing plate 5 is separately fixed on the wet joint reserved steel bar 1 of adjacent two prefabricated case beams/Precast T-Beam 2, described backing plate 5 upper surfaces flush with the beam face 4 of prefabricated case beam/Precast T-Beam 2, described overlay 6 is located on beam face 4 and backing plate 5 and with backing plate 5 and is fixed, the width of described overlay 6 is greater than wet seam hole 3 width.
Preferably, described safeguard structure also comprises tied silk, and described backing plate 5 is fixed by tied silk colligation with wet joint reserved steel bar 1.
Preferably, described safeguard structure also comprises iron nail, and described overlay 6 is fixed by iron nail with backing plate 5.
Preferably, described backing plate 5 is waste and old batten.
Preferably, described overlay 6 is waste and old plank or bamboo offset plate.
The utlity model has following useful effect:
The utility model construction is simple, easy to operate, and the wet seam hole that can be less than 80cm to width between Bridge Beam is effectively protected, and can effectively cover wet seam hole, can bear actual load, ensures constructor's safety; In the utility model, overlay adopts waste and old plank or bamboo offset plate, and backing plate adopts waste and old batten, and immobilization material adopts waste and old iron nail and tied silk, under the prerequisite of guaranteeing effect, pursue environmental protection, efficient, low consumption, make overall plans, the maximized green construction pattern of comprehensive benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, wet joint reserved steel bar; 2, prefabricated case beam/Precast T-Beam; 3, wet seam hole; 4, beam face; 5, backing plate; 6, overlay.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, wet seam hole safeguard structure between a kind of Bridge Beam, be located on the prefabricated case beam/Precast T-Beam 2 with wet joint reserved steel bar 1, protect for 3 places, two prefabricated case beams/Precast T-Beam, 2 wet seam hole to adjacent, comprising: backing plate 5, overlay 6, tied silk, iron nail; Described backing plate 5 is fixed on the wet joint reserved steel bar 1 of adjacent two prefabricated case beams/Precast T-Beam 2 by tied silk colligation respectively, described backing plate 5 upper surfaces flush with the beam face 4 of prefabricated case beam/Precast T-Beam 2, described overlay 6 is located on beam face 4 and backing plate 5 and by iron nail and is fixed with backing plate 5 and fix, and the width of described overlay 6 is greater than wet seam hole 3 width.
Described backing plate 5 adopts waste and old batten, and overlay 6 adopts waste and old plank or bamboo offset plate, and tied silk, iron nail also adopt waste and old tied silk and waste and old iron nail.
When concrete enforcement, carry out according to following step:
1, prepare material: backing plate 5 is waste and old batten, and overlay 6 is waste and old plank, bamboo offset plate etc., and immobilization material is waste and old iron nail, tied silk etc.
2, preparation: select width to be not less than the overlay 6 at wet seam hole 3, longitudinal spliced seamless, attractive in appearance, waste and old iron nail is done to straight processing;
3,, for preventing waste and old plank, bamboo offset plate insufficient strength, support not yet in effect under plank or bamboo offset plate, adopts waste and old batten that wet joint reserved steel bar 1 and beam face 4 are leveled up, and along the longitudinal both sides of wet joint reserved steel bar 1, the old batten of one waste discharge is respectively set;
4, prevent cover waste and old plank, bamboo offset plate move, adopt tied silk by the two ends colligation of waste and old batten on wet joint reserved steel bar 1, then by cover waste and old plank, bamboo offset plate follow closely on waste and old batten with waste and old iron nail;
The utility model overall structure is simple, easy to operate, aesthetic in appearance, allows and does not use the workman of instrument to be difficult to mobile overlay 6, and can effectively bear human body and small-sized machine load, meets on-the-spot needs; In the time that 3 places, wet seam hole no longer need to continue sealing, directly with crow bar, waste and old plank or veneer are levered up, because waste and old batten is only with the simple colligation of tied silk, overlay 6 only uses waste and old iron nail simply fixing, levers up rear waste and scrap and still can reuse.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
