Description

Structure for adjusting gradient of prefabricated T-shaped beam boot

Technical Field

The utility model relates to a transfer slope structure, especially a structure for adjusting prefabricated T roof beam boots slope.

Background

With the continuous development of national infrastructure, the bridge structure across terrains such as rivers, valleys and the like is different day by day, the prefabricated T-beam is very common as the upper structure of the bridge, the bridge is often provided with a certain longitudinal slope in design, the longitudinal slopes of different bridge sections are different, the size of a certain longitudinal slope of a bridge across is realized by the difference of the heights of two pier columns which cross the front and the rear, the heights of the top surfaces of the bolsters and the supports above the front and the rear pier columns are different due to the difference of the heights of the pier columns, because the top surfaces and the bottom surfaces of the T-beam are parallel to each other, if the T-beam end bottom surface is directly erected without processing, the bottom surface of the T-beam cannot be in close contact with the supports on the front and the rear pier columns, the supports and the front and the rear pier columns have a certain gap, the supports can deform due to uneven stress, the service life of the T-beam is further influenced, and in order to avoid the situation, a beam, The support is in close contact, so that uneven stress on the support is avoided. Because the longitudinal slopes of different bridge sections are different, the corresponding gradient of the beam shoe also needs to be adjusted continuously.

SUMMERY OF THE UTILITY MODEL

The utility model provides a structure for solving the technical problem that exists among the known art and be used for adjusting prefabricated T roof beam boots slope.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a structure for adjusting prefabricated T roof beam boots slope, this structure is including setting up on pedestal tip top surface, along the one-level step face that sinks that pedestal length direction set up put two reinforcing bars that extend along the whole width of pedestal on the step face that sinks, two the reinforcing bar is parallel to each other, interval arrangement, diameter are different, and one of them is the coarse reinforcement, and one is the thin reinforcing bar with the coarse reinforcement upper berth is equipped with the roof beam boots bottom plate, the roof beam boots bottom plate is connected with T roof beam arrangement of reinforcement, touches with T roof beam side form and end mould and connects.

The diameter of the thick steel bar is 15-30mm, and the diameter of the thin steel bar is 8-15 mm.

The distance between the thick steel bars and the thin steel bars is 800-1200 mm.

The utility model has the advantages and positive effects that: the T-beam shoe gradient can be conveniently and accurately adjusted and determined by adjusting the distance or the diameter difference of the thick and thin steel bars and the combination of the thick and thin steel bars through adopting the structure that the thick and thin steel bars are arranged on the first-level sinking step surface lower than the platform surface and adopting the structure of the two steel bar supporting beam shoe bottom plates, and the operation is simple and the adjustment is convenient. And the utility model discloses simple structure, the preparation is convenient, and the cost is low, can reuse, can reduce construction cost.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a pedestal; 2. coarse steel bars; 3. fine steel bars; 4. sinking the step surface; 5. a bottom plate of the beam boot.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1, the structure for adjusting the gradient of the prefabricated T-beam shoe comprises a first-level sinking step surface 4 which is arranged on the top surface of the end part of a pedestal 1 and is arranged along the length direction of the pedestal 1, two steel bars which extend along the whole width of the pedestal are placed on the sinking step surface 4, the two steel bars are parallel to each other, are arranged at intervals and have different diameters, one steel bar is a thick steel bar 2, the other steel bar is a thin steel bar 3, a beam shoe bottom plate 5 is laid on the thin steel bar 3 and the thick steel bar 2, and the beam shoe bottom plate 5 is connected with a T-beam reinforcing bar and is in contact connection with a T-beam side mold and an end mold.

In this embodiment, it is recommended that the diameter of the thick steel bar 2 is 15-30mm, and the diameter of the thin steel bar 3 is 8-15 mm. The distance between the thick steel bars 2 and the thin steel bars 3 is recommended to be 800-1200 mm.

Since the two reinforcing bars placed in parallel are different in diameter, the shoe bottom plate 5 placed thereon is not horizontal but exhibits a slope, and the difference in slope can be realized by adjusting the distance between the two reinforcing bars.

The working principle of the structure is as follows: two steel bars, for example, a phi 10 steel bar and a phi 20 steel bar, are placed on the sinking step surface of the pedestal in parallel along the width direction of the pedestal 1, then the bottom plate of the beam shoe is placed on the two steel bars, the height difference of the contact part of the bottom plate of the beam shoe and the two steel bars is 20mm-10mm, which is 10mm, if the height difference is fixed, the distance between the two steel bars can be adjusted at will, and if the distance is 1000mm, the gradient of the bottom plate of the beam shoe is 1%, that is, the gradient of the beam shoe is 1%. The diameter of the two steel bars can be adjusted by fixing the distance between the two steel bars to adjust the slope, or the two methods are adopted to adjust the slope, when the T beam climbs the slope, the phi 10 steel bars are arranged on the inner side, the phi 20 steel bars are arranged on the outer side, when the T beam descends the slope, the phi 10 steel bars are arranged on the outer side, the phi 20 steel bars are arranged on the inner side, after the slope adjustment is completed, the T beam reinforcing bars are bound on the pedestal, the beam shoe bottom plate and the T beam reinforcing bars are welded and connected, after the T beam reinforcing bars are bound, the template assembly is carried out, the side molds on the two sides of the pedestal and the end molds on the end part are closely attached to the two sides and the ends of the.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
