Description
Technical field
The invention belongs to engineering construction fields, especially bridge field, and in particular to steel-is combined after wet seam built in one kind
Mixed bondbeam combines steel-to mix bridge and associated construction method of the bondbeam as bridge floor using after the built-in wet seam, for mentioning
Height combines the effective prestress of negative moment section of beam concrete slab.
Background technique
In engineering construction field, steel-mixes bondbeam compared with beams of concrete, from heavy and light, adaptable；Especially led in bridge
Domain, compared with girder steel, rigidity is big, bridge floor durability is good, operation maintenance costs is low, economy is high；Concrete slab is in bondbeam
The lateral deflection bearing capacity for having the effect in conjunction with flange of beam and floorings concurrently, being conducive to improve girder steel.Also, concrete slab can be
It is cast-in-place on girder steel through having set up, can be to lift after prefabricated, construction is flexible and convenient.Therefore, bondbeam is more and more in engineering
Ground is applied.
In order to make the concrete slab total cross-section of bondbeam be pressurized, generally require in concrete slab inner stretch-draw prestressing force muscle.It passes
The steel-of system mixes bondbeam and generally arranges WELDING STUDS on girder steel, is combined into concrete slab with girder steel by cast-in-place or wet seam
The presstressed reinforcing steel of whole post-stretching concrete slab.
But in the traditional structure and construction method, a part of prestressing force is transmitted on steel construction by WELDING STUDS, a side
Face reduces the effective prestress on concrete slab, in order to reach the use that the pre-compressed effect of concrete slab must increase presstressed reinforcing steel
Amount；On the other hand, the load that the prestressing force on girder steel increases girder steel is transmitted to by WELDING STUDS, needs to increase girder steel section,
Increase construction weight and materials；Especially hogging moment area needs to arrange a large amount of prestressing force in order to avoid concrete slab cracking
Muscle causes significant wastage；Also, cast-in-place or wet seam construction is cumbersome, long in time limit.
