Description
Technical field
The invention belongs to bridge diaphragm fields, and being related to one kind can cause to misplace to avoid fabricated T beam bridge rigging error
The Novel steel tabula girder construction of problem.
Background technique
In recent years, communications and transportation is quickly grown, and the demand of means of transportation is also increasing.With the increasing of operation load
Add, especially the effect of overload of vehicle, the destruction of diaphragm has been increasingly becoming one of Common Diseases of bridge.Diaphragm simultaneously
During assembled, connection, it may appear that it is non-coplanar between diaphragm, occur faulting of slab ends, the poor welding quality of tabula beam steel or
The problems such as being poured leakiness.In practice of construction practice, due to the rigging error of prefabricated beam bridge, it is easy to generate diaphragm dislocation
Phenomenon.So the form that diaphragm destroys, mostly since the construction problem of itself causes, traditional diaphragm needs are carried out into one
The upgrading and change of step adapts to environment of today, and requires better economy, durability and practicability.
Steel diaphragm is a kind of more economical, efficiently structure, and compared with other diaphragms, steel diaphragm has self weight
Gently, the advantages such as strong, easy construction of tensile capacity, and the total construction period designed and constructed is less.During maintenance and reinforcement, steel is horizontal
It can also construct in the case where having a good transport and communication network every beam.
Summary of the invention
In order to overcome the shortcomings of the easy dislocation of existing steel diaphragm, the present invention provides one kind 3 adjustable steel truss formula T
Using this design the stress performance and globality of bridge diaphragm not only can be improved, but also solve due to dress in beam diaphragm
The problem of may cause diaphragm dislocation with error, while to guarantee the convenience of construction, it is the disease of conventional concrete diaphragm
Evil proposes new solution.
The technical solution adopted by the present invention to solve the technical problems is:
Two pieces of band edge of a wing nodes of one kind 3 adjustable steel truss formula T beam diaphragms, including bottom or so and two pieces of parallel sections
Contact plate, two pieces of described bottom or so band edge of a wing gusset plate as the 1st and the 2nd node, the 1st and the 2nd node in phase
There are the pre-buried T-steels of bolt slot to be connected by screw bolts for adjacent T web bottom；3rd node uses two pieces of parallel nodes
Plate wears reinforcing bar after-pouring in the post-cast strip concrete between adjacent T flange of beam, is connected between three nodes by steel-pipe welding
Triangular truss structure, and ribbed stiffener is welded close at steel pipe in No. 1, No. 2 node.
Further, the 3rd node makes full use of wet joint spaces position, and top half protrudes into wet seam position before pouring
It sets, preformed hole, which is worn, to be poured section with after after reinforcing bar and pour together.
The bolt slot is kidney slot.It is of course also possible to be other shapes, as long as bolt may be implemented position and adjust i.e.
It can.
In the present invention, using 3 truss structures, a determining plane, and opposite and multipoint configuration may be constructed at 4 points
More stability and good stress performance are connected with better globality with T beam body.
3 adjustable steel truss formula T beam diaphragms facilitate batch production to make and produce using whole prepackage, while effectively drop
The difficulty of low construction site.Scene need to be only bolted, and cost of labor is saved.
In the present invention, when installation, first integral prefabricated end joist formula steel diaphragm carries out erection installation again.First pass through adjustment bottom
Portion is bolted position and adjusts diaphragm position transverse direction, the longitudinal error that the assembly of T beam generates.Muscle position is worn by top again to adjust
Diaphragm is vertical and error of tilt, and since the 3rd point of truss in the concrete of post-cast strip, it is unfavorable that vertical error will not generate structure
It influences, so that 3 points of realization is adjustable.
Beneficial effects of the present invention are mainly manifested in: the stress performance and globality of bridge diaphragm not only can be improved,
And solve the problems, such as to may cause diaphragm dislocation due to rigging error, while to guarantee the convenience of construction, it is mixed for tradition
The disease of solidifying soil diaphragm proposes new solution.

In figure: the 1st node of 1-, the 2nd node of 2-, the 3rd node of 3-, 4- batter brace steel pipe, 5- truss stull steel
Pipe, the pre-buried T-steel of 6-, 7- ribbed stiffener, 8- bolt, 9- bolt slot, 10- preformed hole.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig.1~Fig. 4, two pieces of band edge of a wing nodes of one kind 3 adjustable steel truss formula T beam diaphragms, including bottom or so
Plate and two blocks of parallel nodes plates, two pieces of described bottom or so band edge of a wing gusset plate is as first node 1 and the 2nd node 2, Section 1
Point 1 and the 2nd node 2 with adjacent T web bottom there are the pre-buried T-steel 6 of bolt slot 9 use bolt 8 connect；3rd
Node 3 wears reinforcing bar after-pouring in the post-cast strip concrete between adjacent T flange of beam using two blocks of parallel nodes plates, three node points
Between by steel pipe 4,5 welded connecting welded at triangular truss structure, and in first node 1 and the 2nd node 2 close at steel pipe
Connect ribbed stiffener 7.
Further, the 3rd node 3 makes full use of wet joint spaces position, and top half protrudes into wet seam before pouring
Position, preformed hole 10, which is worn, to be poured section with after after reinforcing bar and pours together.
The bolt slot 9 is kidney slot.It is of course also possible to be other shapes, as long as bolt 8 may be implemented position and adjust i.e.
It can.
The present embodiment may be constructed a determining plane, and opposite and multipoint configuration at 4 points using 3 truss structures
More stability and good stress performance are connected with better globality with T beam body.
3 adjustable steel truss formula T beam diaphragms facilitate batch production to make and produce using whole prepackage, while effectively drop
The difficulty of low construction site.Scene need to only carry out high-strength bolt connection, save cost of labor.
As shown in figure 3, the 3rd, top node 3 makes full use of wet joint spaces position, top half protrudes into wet connect before pouring
Stitch position, preformed hole 10, which is worn, to be poured section with after after reinforcing bar and pour together.
As shown in figure 4, first integral prefabricated end joist formula steel diaphragm carries out erection installation again when steel diaphragm is installed.First
Diaphragm position transverse direction, the longitudinal error that the assembly of T beam generates are adjusted by adjusting bottom bolts link position.It is worn again by top
Muscle position adjusts that diaphragm is vertical and error of tilt, and since the 3rd node of truss is in the concrete of post-cast strip, vertical error will not
Have an adverse effect to structure, so that 3 points of realization is adjustable.
