The girder steel both ends are fixed on the concrete column of both ends through the installation of terminal end plate, and the perpendicular web both sides symmetrical arrangement welding of girder steel has the second stiffener, terminal end plate is fixed on the concrete column through back anchor bolt, first stiffener is installed in the angle of intersection department of concrete column wall with the girder steel, and first stiffener adds the end plate with girder steel, terminal end plate and back and is connected, the diagonal bracing difference welded fastening at lower chord both ends is on first stiffener, perpendicular web member and diagonal bracing have been fixed in the installation between girder steel and lower chord, the back adds the end plate needs aequilate arranging in terminal end plate below to anchor bolt is connected with the concrete column through the back.
Description
Technical field
The utility model relates to a kind of steel truss structure reducing girder steel deformation, belongs to construction engineering technical field.
Background technology
The impact that the factors such as the initial imperfection by sequence of construction, the initial bending of girder steel and node are caused so that steel
The deformation of beam can exceed permissible value, and security and normal use to structure impact.Now, remove girder steel and reinstall
Still cannot solve the excessive problem of deformation；Again make and the cost of installation component is too high, it is not recommended that use.Therefore, lack at present
A kind of steel truss structure system that can reduce girder steel deformation simply and effectively.
Content of the invention
The purpose of this utility model is, is deformed excessive problem in order to solve existing girder steel by what many factors caused, this
Utility model provides a kind of steel truss structure reducing girder steel deformation.
The technical solution of the utility model is: a kind of steel truss structure reducing girder steel deformation, including girder steel, concrete
Post, end end plate, rear anchor bolt, after add end plate, stiffener, lower boom and web member.
Web member includes perpendicular web member and diagonal web member, and stiffener includes the first stiffener and the second stiffener.
Girder steel two ends are fixed on the concrete column of two ends by end end plate, and the perpendicular web bilateral symmetry of girder steel is arranged
It is welded with the second stiffener；End end plate is fixed on concrete column by rear anchor bolt；First stiffener is arranged on coagulation
At the angle of cut of earth pillar metope and girder steel, the first stiffener and girder steel, end end plate and after add end plate connection；Lower boom two ends oblique
Web member is respectively welded and is fixed on the first stiffener；Install between girder steel and lower boom and secure perpendicular web member and diagonal web member.Institute
Adding end plate after stating needs wide being arranged in below end end plate, and is connected with concrete column by rear anchor bolt.
Described diagonal web member inserts in the first stiffener after needing at one end perforate, and by being welded to connect.Described diagonal web member with
Between lower boom, angle is 45 °.
Girder steel forms truss structure with lower boom and web member after need to being pushed up back original state with jack again.
The beneficial effects of the utility model are, owing to the utility model uses girder system theoretical, to improving girder steel amount of deflection
Very good effect can be got.The utility model structure has the advantage of reasonable stress, simple structure and easy construction, can be effectively satisfied
The requirement of girder steel deformation.

Detailed description of the invention
Detailed description of the invention of the present utility model is as shown in Figure 2.
The present embodiment is a kind of reduces the steel truss structure of girder steel deformation, including girder steel the 1st, concrete column the 2nd, end end plate the 3rd, after
Anchor bolt the 4th, after add end plate the 5th, stiffener, lower boom 8 and web member.
Described stiffener includes the first stiffener 6 and the second stiffener 7；Described web member includes diagonal web member 9 and perpendicular web member 10；
Described first stiffener 6 and girder steel the 1st, end end plate 5 and after add end plate 6 and be connected；Two ends diagonal web member 9 inserts after needing at one end perforate
In first stiffener 6, and by being welded to connect.
Adding end 5 plate after as it is shown on figure 3, needs wide being arranged in below end end plate 3, and passes through rear anchor bolt 4 and coagulation
Earth pillar connects 3.
As shown in Figure 4, the second stiffener 7 need to be arranged symmetrically in girder steel and erects at web member both sides 3.When girder steel 1 will with jack
It forms truss structure with diagonal web member the 9th, perpendicular web member 10 and lower boom 8 after pushing up back original state again.
