The utility model content:
In order to overcome the deficiency of existing shrinkage joint Sealing Technology, it is People's Bank of China's overpass structure shrinkage joint black box that the purpose of this utility model is to provide a kind of reasonable in design, easy for installation, durable People's Bank of China's overpass shrinkage joint special (purpose) rubber waterstop.
The utility model is by the following technical solutions:
A kind of People's Bank of China overpass structure shrinkage joint black box comprises the waterstop that is installed on the shrinkage joint, overlays on the cover plate of waterstop two end surfaces and is used for waterstop and cover plate are fixed to a plurality of screws of bridge basic unit; Described waterstop places the part between the shrinkage joint to have bending structure.
Wherein, described waterstop is made by elastomeric material, has the widthwise edge and the bending segment that is connected widthwise edge of the horizontal direction of symmetry.
Described bending segment is the W type that seamlessly transits, single V-type or two above V-type couplings, single U type or coupling of two above U types or O types.
Described cover plate adopts materials processing moulding such as stainless steel, and symmetry is installed on the waterstop both sides, and it has the straight section that the widthwise edge with waterstop is complementary and the bending section at two ends.
The edge shape and the thickness of described cover plate outer rim bending section and waterstop are complementary, and the bending segment upper limb shape of inner edge bending section and waterstop is complementary.
Establish a plurality of screws and screw fit on the described cover plate with fixing waterstop.
The utlity model has following characteristics:
1. adopt the special bonding agent that the sealing plane of rubber fastening band seal area is pasted on the basic unit plane of bridge expanssion joint both sides, to reach good static sealing purpose, the seal area of rubber fastening band may be plane or be polyline shaped according to the concrete condition of engineering.The breathing zone of rubber fastening band is multiple shapes such as W, V, O, U, determines according to design width, the structure types at bridge construction shrinkage joint.
2. the breathing zone both sides of the rubber fastening band cover plate that adopts material such as stainless steel to manufacture is protected; and adopt holding screw to fix; lid surface can be plated coat with rubber matter or be adopted hot-spraying technique to carry out texturing, to reach good skidproof effect and to improve presentation quality.
3. People's Bank of China's overpass structure shrinkage joint black box has fundamentally been eliminated the hidden danger that People's Bank of China overpass structure shrinkage joint leaks, and have that interchangeability is strong, the characteristics of long service life, good looking appearance.Stopped the appearance of phenomenons such as original shrinkage joint sealer ftractures, leaks, steel work corrosion.
Description of drawings:
Fig. 1 is the utility model People's Bank of China overpass structure shrinkage joint seal component architecture sectional drawing;
Fig. 2 is that the utility model People's Bank of China overpass structure shrinkage joint black box is installed the back generalized section;
Fig. 3 is that the utility model People's Bank of China overpass structure shrinkage joint black box is installed the back schematic perspective view.
The specific embodiment:
As shown in Figure 1, the utility model People's Bank of China overpass structure shrinkage joint black box comprises waterstop 1 (comprising seal area and breathing zone), cover plate 2 and presses closer screw 3.Wherein:
Waterstop 1 adopts molded vulcanization technology one to be moulded by the rubber elastomeric material, and the widthwise edge 11 of symmetrical horizontal direction forms seal areas, and the bending segment 12 that connects widthwise edge forms breathing zones, and widthwise edge 11 is punished near outer rim and established two groups of through holes; Bending segment 12 preferably is the W type that seamlessly transits, this kind pattern has two downward curved and curved (being equivalent to the coupling of two V-structures) that make progress, bending segment 12 other similar form of structure also can be single V-type or a plurality of V-type coupling, can change according to the width at the shrinkage joint of need sealings, as the single V-type of the narrow use in shrinkage joint, the shrinkage joint is wide then uses many V-types.Certainly, according to flexible principle, bending segment can also be for multiple shapes such as V, the O of distortion, U, as long as can realize Telescopic.
The utility model People's Bank of China overpass structure shrinkage joint black box installation process following (wherein label is referring to Fig. 2):
(1) detect bridge expanssion joint basic unit's steel work or concrete base layer B, keep shrinkage joint G width unanimity, both sides, the shrinkage joint B of basic unit is in same horizontal plane;
