Description
Technical field
The invention belongs to bridge construction technical field, be specifically related to a kind of T-shaped beam bridge and construction method thereof that bottom lateral bracing is set.
Background technology
For highway prestressed concrete T beam bridge, China has worked out standard design drawing for 25m, 30m, 35m, 40m across footpath, and T-shaped beam bridge adopts in a large number in highway construction.The T-shaped beam of such bridge precast yard or beam factory prefabricated, bridge location erected on site is constructed, the cross section of T-shaped beam is frange plate-web-water chestnut form, prestressed concrete T beam many employings post stretching longitudinally arranges prestressed reinforcement along base plate and web, and between multi-disc T-shaped beam, lateral connection relies on the cast-in-place seam between T beam diaphragm and frange plate stem grafting to stitch.Its construction method is first by prefabricated T-shaped beam hoisted in position, then the diaphragm place between adjacent T-shaped beam sets up template, concreting, welded flange plate and diaphragm reserve steel plate, by stem grafting seam and concrete wet seam by each piece of T-shaped beam along bridge lateral connection become entirety.Be connected owing to only reserving steel plate by diaphragm with frange plate top board between adjacent T-shaped beam, poor along bridge transverse integral, integral bridge is antitorque more weak, and easily there is the crack of seaming position place along bridge longitudinal direction, cause vehicle pitching, affect normal use and the durability of bridge, when situation is serious, there will be the T-shaped beam stress of monolithic, bury hidden trouble to bridge traffic safety and structure durability.
Summary of the invention
The object of the present invention is to provide a kind of T-shaped beam bridge and construction method thereof that bottom lateral bracing is set.
Based on above-mentioned purpose, the present invention adopts following technical scheme:
A kind of T-shaped beam bridge that bottom lateral bracing is set, comprise the two T-shaped side bars be oppositely arranged, T-shaped central sill is provided with continuously in the middle of two T-shaped side bars, each T-shaped side bar is provided with several diaphragms by the side of T-shaped central sill, each T-shaped central sill both sides are equipped with several diaphragms, each T-shaped side bar or T-shaped central sill are equipped with water chestnut encased steel plate, several rectangle bottom lateral bracing unit are provided with between adjacent T-shaped beam, described each rectangle bottom lateral bracing unit comprises point bottom lateral bracing gusset plate being located at four drift angle places, be in just to and/or diagonal position place two bottom lateral bracing gusset plates between be connected with bottom lateral bracing shaped steel, wherein each T-shaped beam respectively arranges two bottom lateral bracing gusset plates, on the bottom surface that bottom lateral bracing gusset plate is located at water chestnut encased steel plate between same T-shaped beam adjacent twice diaphragm or side.
The thickness of described bottom lateral bracing gusset plate is not less than the thickness of water chestnut encased steel plate.
Described bottom lateral bracing shaped steel is angle steel, channel-section steel or i iron.
The described construction method arranging the T-shaped beam bridge of bottom lateral bracing, comprises the following steps:
(1) prefabricated reinforced concrete or prestressed concrete T beam: the water chestnut encased steel plate making T-shaped beam, steel form, prefabricated T-shaped side bar and T-shaped central sill is settled by design and construction code requirement, water chestnut encased steel plate is connected with T-shaped beam baseplate reinforcing bar, maintenance prefabricated T-shaped beam, removes steel form except water chestnut encased steel plate (water chestnut encased steel plate when pouring into a mould as steel form);
(2) bottom lateral bracing gusset plate welding: bottom lateral bracing gusset plate is welded in the bottom surface of the water chestnut encased steel plate between the adjacent twice diaphragm of same T-shaped beam or side;
(3) T-shaped beam is lifted: the prefabricated T-shaped beam completed is transported to bridge construction place hoisted in position;
(4) the cast-in-place seam of T-shaped beam diaphragm and the construction of frange plate stem grafting seam: conveniently the design of T-shaped beam lateral connection and construction requirement complete the construction of frange plate stem grafting seam, the cast-in-place seam of diaphragm;
(5) bottom lateral bracing welding or bolt: from T-shaped beam-ends position, between adjacent T-shaped beam, just to and/or diagonal position place two bottom lateral bracing gusset plates between welding or bolt bottom lateral bracing shaped steel, finally between adjacent T-shaped beam, form several rectangle bottom lateral bracing unit, finally conveniently technique completes the construction of whole bridge span structure.
The thickness of the water chestnut encased steel plate described in step (1) is not less than the thickness of steel form.
When adopting technical scheme of the present invention, the water chestnut encased steel plate in step (1) longitudinally can not be elongated along T-shaped beam, and encased steel plate disconnects near diaphragm, avoids T-shaped beam overreinforced.
The present invention is by arranging water chestnut encased steel plate, and this steel plate is connected with T-shaped beam baseplate reinforcing bar, and during T-shaped beam prefabricated construction, this steel plate is as steel form; T-shaped beam is built prefabricated, removes other position template, and the steel plate at water chestnut position is not removed, and at the side of steel plate or bottom surface welding bottom lateral bracing gusset plate; From T-shaped beam-ends position, between adjacent T-shaped beam, just to and/or diagonal position place two bottom lateral bracing gusset plates between welding or bolt bottom lateral bracing shaped steel, finally between adjacent T-shaped beam, form several rectangle bottom lateral bracing unit, the holistic resistant behavior of the T-shaped bridge of assembling is improved with this, overcome existing T-shaped beam and only link by the stem grafting seam between frange plate, diaphragm cast-in-situ concrete the shortcoming causing the overall stress-bearing capability of the T-shaped beam bridge of assembling more weak, effectively enhance the overall stress-bearing capability of the T-shaped beam bridge structure of assembling; Meanwhile, the steel plate of water chestnut outer wrapping can avoid beam base concrete to ftracture, and improves the durability of T-shaped beam.Prefabricated and the existing T-shaped beam prefabricated construction technology of this kind of T beam is consistent, to equipment and technical requirements constant, only simply replace the prefab form at water chestnut position, the steel plate of parcel can weld or bolt bottom lateral bracing easily.The T-shaped beam bridge easy construction arranging bottom lateral bracing of the present invention, to holistic resistant behavior and the durability effect of having greatly improved of the T-shaped beam bridge of assembling.
