Description

A steel structure conversion truss

technical field

The utility model relates to a steel structure truss, in particular to a steel structure transfer truss, which belongs to the technical field of construction.

Background technique

At present, in engineering design, it is often encountered that the architectural function requirements of drawing columns at the bottom of the building to form a large-span space. The traditional method is to cancel the frame columns at this location and above each floor, and adopt orthogonal or oblique well-shaped beam floors, but this structural arrangement will cause single-span frames to appear locally in the overall structure, which is not conducive to the overall seismic resistance of the structure. . Orthogonal or oblique well-shaped beam floor girder height and beam slab self-weight are large, the net building height of the room is reduced and the economy is poor.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide a steel structure conversion truss, which can not only cancel the frame column of the first floor at this position, but also support the frame columns at this position of two or more floors .

In order to achieve the above object, the technical solution of the utility model is achieved in this way:

A steel structure conversion truss, including two uprights, between the two uprights there is an upper chord and a lower chord connecting the two uprights horizontally, the two ends of the upper chord are connected with the tops of the two uprights, the vertical distance between the upper chord and the lower chord is the height of the floor where it is located; between the upper chord and the lower chord, there is a diagonal rod for support, and the diagonal rod connects the upper chord and the lower chord in an inclined manner; the column is welded H-shaped steel, and the outer surface is equipped with studs , the steel frame formed by the column and the studs is wrapped with concrete to form a reinforced concrete column; the upper chord and the lower chord are welded H-shaped steel, and the outer surface is evenly provided with studs, the steel frame formed by the upper chord and the studs and The steel frame formed by the bottom chords and studs is covered with concrete to form reinforced concrete beams.

A column corbel is provided at the connection between the column and the upper chord and the lower chord, and the two ends of the upper chord and the lower chord are respectively connected to the column corbel by bolts to realize the connection with the column.

The diagonal rods are welded H-shaped steel, and all the diagonal rods are connected end-to-end in a "W" manner; chord corbels are arranged at the connection between the upper chord and the lower chord and the diagonal rods, and all the diagonal rods are connected by bolts Connect with chord corbels.

Compared with the prior art, the utility model has the following beneficial effects:

1. The truss is a plane truss, hidden in the building wall, which is beautiful, economical and convenient for construction.

2. The truss has a relatively large rigidity in the plane, and the upper and lower chords outside the plane are connected by floors, which can ensure the overall stress stability of the conversion truss.

Description of drawings

Fig. 1 - structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, it can be seen from the figure that the steel structure conversion truss of the present invention includes two uprights 1, and an upper chord 2 and a lower chord 3 connecting the two uprights 1 are arranged horizontally between the two uprights 1, and the upper chord 2 is two The end is connected with the top of two columns 1, and the vertical distance between the upper chord 2 and the lower chord 3 is the height of the floor. Between the upper chord 2 and the lower chord 3, there is a supporting diagonal rod 4, and the diagonal rod 4 connects the upper chord 2 and the lower chord 3 in an oblique manner. The column 1 is welded H-shaped steel, and the outer surface is covered with studs 5 according to the technical requirements. Reinforced concrete columns. The upper chord 2 and the lower chord 3 are welded H-shaped steel, and the outer surface is covered with studs 5 according to the technical requirements. form reinforced concrete beams.

A column corbel 6 is provided at the connection between the column 1 and the upper chord and the lower chord, and the two ends of the upper chord 2 and the lower chord 3 are respectively connected to the column corbel 6 by bolts to realize the connection with the column.

A chord corbel 7 is arranged at the connection between the upper chord 2 and the lower chord 3 and the diagonal rod, and all the diagonal rods 4 are connected with the chord corbel 7 by bolts. The oblique web bar 4 is an exposed section steel, and the upper and lower brick walls are exposed in the room when building by laying bricks or stones, but not exposed outside the room. In actual design, the diagonal webs 4 are welded H-shaped steels, and all the diagonal webs 4 are sequentially connected end to end in a "W" manner, which can better ensure the overall strength of the truss pieces.

With this structural layout, except for the transfer floor (transfer truss), the other floors are arranged with ordinary column net beams and columns, which does not affect the building function and can achieve better economy.

The above embodiments only illustrate the technical solution of the utility model without limitation, although the utility model solution has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solution of the utility model can be modified or equivalent Replacement, without departing from the purpose and scope of the technical solution of the utility model, all of them should be covered by the scope of the claims of the utility model.
