Abstract
The invention relates to a railway bridge pasty fixed expansion joint material and an application construction method, wherein the material is a pasty solid and has excellent expansion performance and adhesive property, when application and construction, a cushion coat is matted on the upper surface of a joint of a beam body, the material is injected into a reservation expansion joint which is arranged on a joint of waterproof layers and the joint of bridge decks on the beam body to solidify, thereby forming the expansion joint. The railway bridge pasty fixed expansion joint material has the advantages of excellent expansion performance, excellent seepage-proofing property, simple and convenient application construction, easy maintenance, long service life, saving steel and reducing cost and the like, and is capable of being widely used to build the railway bridge.
Description
Technical field the present invention relates to a kind of railroad bridge with material and application construction method, and particularly a kind of railroad bridge pasty is expanded joint material and application construction method fixedly.
Background technology is present, building shrinkage joint such as railroad bridge exhausted most use shaped steel and the combination of water proof rubber bar, during use, need shaped steel and the combination of water proof rubber bar are made, be fixed on and will pour into a mould between the two block concrete Bridge Beam heads, both sides fix template, pour into a mould then, build waterproofing course and bridge floor more in the above, make it to become the shrinkage joint of waterproofing course and bridge floor.But the cost of manufacture that shaped steel has is higher, expend steel, working procedure cumbersome, easily get rusty, shortcomings such as short, difficult maintenance of life-span.
Summary of the invention the objective of the invention is to overcome the deficiencies in the prior art, and a kind of novel railway bridge pasty state fixedly expanded joint material and application construction method are provided, and substitutes existing traditional shaped steel and the combination of water proof rubber bar.Advantages such as it has the steel of saving, construction is simple and convenient, cost is low, be difficult for getting rusty, long service life is safeguarded well.
The present invention seeks to realize like this: bed course on the pad on concrete beam body junction, reserve the space, shrinkage joint when construct in the junction of waterproofing course on bed course and waterproofing course, bridge floor and bridge floor again, then, a kind of pasty state that injection has good telescopicing performance and an adhesive property is expanded joint material fixedly, treats that it solidify to form the shrinkage joint.
The invention has the beneficial effects as follows: (1) the present invention can replace steel as a kind of soft connection at shrinkage joint, saves 40% cost of production, has remarkable economic efficiency and social benefit; When (2) using, only need on beam body joint, to put into bed course, inject the expanded joint material that pasty state fixedly has good telescopicing performance in waterproofing course, bridge floor joint again, after treating that it solidifies, waterproofing course and waterproofing course, bridge floor and bridge floor are tightly bonded together, simultaneously have good telescopicing performance again, have that construction is simple and convenient, an advantage of easy care, long service life.(3) expanded joint material can not trickle to both sides during use because be pasty solid, can satisfy the construction of the bridge expanssion joint of different geometries, and volume contraction is very little after solidifying, and is basic equal with bridge floor, both artistic and practical.
Appended drawings 1 is the structural representation of type of the present invention.
Among the figure: on behalf of Liang Ti, (2), (1) represent bed course, (3) to represent waterproofing course, (4) to represent bridge floor, (5) to represent shrinkage joint, (6) to represent bridge pier.
The invention will be further described for an embodiment below in conjunction with accompanying drawing 1 for the specific embodiment.The expanded joint material that pasty solid is had good telescopicing performance is got ready at first, earlier; Then, as shown in Figure 1,, when cast, pour into recessed relatively the top part of the top two beam bodies of railway bridge bridge pier (6) (1) junction; During construction, at beam body (1) placement bed course (2) above the junction, then, the size dimension that on bed course (2), requires according to the shrinkage joint, carry out the construction construction of both sides, shrinkage joint waterproofing courses (3) and bridge floor (4), after construction finished, the pasty solid expanded joint material that will have good telescopicing performance and adhesive property injected shrinkage joint (5) reservation place that stays, and treated to get final product after it solidifies.
Claims (1)
1, fixedly expanded joint material and application construction method of railroad bridge pasty, this material is a pasty solid, during application and construction, fill up bed course (2) above the joint at beam body (1), this material is injected in the reservation shrinkage joint of waterproofing course (3) and waterproofing course (3) above the beam body joint, bridge floor (4) and bridge floor (4) junction, allow its curing, form shrinkage joint (5), it is characterized in that adopting the pasty solid chemical materials as expanded joint material.
