Description

[0002] Girder With Cross Beam [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction field, and more particularly, to a girder integrated structure for integrating two or more girders using a cross beam integrated girder constructed by pre-casting a cross beam.

Generally, when the girder bridges are constructed, the girders are mounted on the bridge piers, and the formers are assembled on the upper part of the fixed girders.

However, the girder having the upper plate formed on the upper part (including the girder extended with the upper flange) has a problem that the girder is deformed due to the load transmitted from the upper plate because the area of the upper plate is larger than that of the girder, Lt; / RTI >

In order to solve this problem, a separate beam is formed on the side surface of the girder so as to mutually connect with a neighboring girder disposed adjacent to the girder, thereby dispersing the load transferred to the girder from the upper plate formed on the girder and preventing the girder from being conducted.

However, the construction method of assembling the formwork on the upper part of the girder on the bridge pier and pouring the concrete on the site takes a long time until the concrete poured in the form is cured and there is a problem of delays due to the weather and weather .

In addition, since an operator has to work in a high-priced structure for a long time, an industrial accident such as a fall of an operator may occur.

In order to solve this problem, it is necessary to construct the bridge girder which is formed on the girder which is mounted on the bridge pier and the side girder which is formed on the side of the girder by using the prestressed concrete (PSC) method or the reinforced concrete method Girder, top plate, and side beam are assembled and mounted on a pier.

However, such an integration method requires the use of a large crane because it requires the mass of a large structure, and it is difficult to apply the structure to a large structure due to limitations of the structure that can be loaded depending on the capacity of the crane.

In addition, due to the difficulty of supplying and receiving the crane, the construction period is lengthened, and there is a problem in that the difficulty of the site construction due to the buoyant and lumbering work is increased.

A conventional technique having the above-described problems will be described below.

It is also to be understood that the terms first, second, etc. used hereinafter are merely reference numerals for distinguishing between identical or corresponding components, and the same or corresponding components are defined by terms such as first, second, no.

In addition, the term " coupled " is used not only in the case of direct physical contact between the respective constituent elements in the contact relation between the constituent elements, but also means that other constituent elements are interposed between the constituent elements, Use them as a concept to cover each contact.

The crossbeam-integrated girder according to the present invention is used in a structure including a plurality of girders (1, 2).

Specifically, in the formation of a structure including a girder, it is common to mount a girder on the upper part of a foundation structure such as a pier or a pillar, and to form a top plate on the girder.

However, since the site where the top plate is formed is usually a high place, it is required to perform a work having a high degree of difficulty in the field work such as the installation of the formwork and the casting of concrete. In this process, Lt; / RTI >

Also, since the pre-construction work for forming the upper plate and the curing work for the concrete are required, the construction period is prolonged and the cost of air is increased.

In order to solve such a problem, the present invention is characterized in that the structure of the main body 100 of the girder 1 mounted on a pier or a column is divided into a lower flange 110, an upper flange 120 and a lower flange 110, Shaped girder including an abdomen 130 connecting the upper flange 110 and the lower flange 110 so that the width A of the upper flange 120 is larger than the width B of the lower flange 110, The adjacent upper flanges 120 of the girders of the first and second girders are brought into contact with each other (Fig. 6).

In such a structure, the upper flanges 120 and 120a of the adjacent girders 1 and 2 are brought into contact with each other merely by mounting the girders 1 and 2 on the foundation, so that the upper plate can be naturally formed.

Therefore, it is not required to carry out a separate site work for forming the upper plate. It is sufficient to perform only the pavement construction on the upper surfaces of the upper flanges 120 and 120a of the girders 1 and 2, It is possible to perform the operation directly on the upper flange 120. [

However, since the width of the upper flange 120 is larger than that of the lower flange 110, the center of gravity of the upper flange 120 may be raised to cause the girder 1 to overturn.

In order to solve the problem of overturning of the girder 1, it is required to form the beam 10 connecting the side portions of two adjacent girders 1 and 2 by connecting them.

Since the beam 10 is a structure connecting the side portions of the girders 1 and 2, it is required that the work for forming the beam 10 be performed on the lower surface of the upper flanges 120 and 120a of the girders 1 and 2 do.

The installation position of the crossbeam 10 is required to form a separate temporary structure such as a scaffold, and the problems that may occur in the above-described construction of the top plate are equally involved, so that the advantages obtained by omitting the work of the top plate can be offset .

In order to solve the problem of the installation of the cross bar 10, the present invention proposes a cross bar integrated girder in which the cross bar 10 is integrated.

More specifically, it is a cross-beam type girder including a beam forming portion 200 for forming the beam 10. When the two adjacent girders 1 and 2 are brought into contact with each other, It is a feature of the present invention that the permanent mold for the formation of the permanent mold is formed naturally.

When two adjacent girders 1 and 2 are mounted on the foundation 40, the upper flanges 120 and 120a of the girders 1 and 2 contact each other to form an upper plate, And a permanent mold for forming the cross beam 10 is formed in contact with the cross beam forming parts 200 and 200a.

Accordingly, it is preferable that an end portion of the beam forming portion 200 is formed to an end portion of the upper flange 120 (FIG. 5).

The filling space 20 formed by contacting the two girders 1 and 2 is closed by the other beam forming portion 200a included in the girder 2 adjacent to the beam forming portion 200, (See FIG. 4 and FIG. 8).

When such a structure is adopted, concrete can be injected into the filling space 20 through the placement holes 30 formed on the upper surfaces of the upper flanges 120 and 120a, so that the stability and easiness of the site casting operation can be secured have.

A beam connecting reinforcing bar 300 may be installed in the filling space 20 to serve as a shear key for forming the beam 10.

To this end, it is preferable that a part of the beam connecting ribs 300 is embedded in the main body 100 and a part of the reinforcing bars 300 is exposed to the outside from the inner surface of the filling space forming groove 210 (FIGS. 5 and 8).

The shape of the beam connecting ribs 300 exposed to the outside from the inner surface of the filling space forming groove 210 is preferably a loop shape (FIG. 8).

The cross beam connecting reinforcing bars 300 may be formed in plural along the height direction of the filling space forming groove 210. In this case, it is preferable that the crossbar reinforcing bars 300 included in the girder 1 and the crossbar reinforcing bars 300a included in the adjacent girder 2 can be intersected (FIG. 6).

A reinforcing bar 400 may be further installed in the filling space 20 along the lateral direction of the filling space 20.

In this case, the reinforcing bar 300 may be installed in a direction perpendicular to the cross bar connecting bar 300.

In addition, it is preferable to install the inside of the loop of the cross beam connecting reinforcing bar 300 from the viewpoint of position fixing.

The integrated beam girder according to an embodiment of the present invention corresponds to a unit segment forming a structure, and can be installed in a factory by pre-casting and installed in the field.

In this case, a plurality of beam integrated type girders in which the beam connecting reinforcing bars 300 are embedded and the beam connecting portions 200 are formed are pre-casted and mounted on the upper portion of the foundation 40, It is possible to construct a structure in which the girders 1 and 2 adjacent to each other are connected by the beam 10 only by filling the concrete in the space 20. [

The width of the upper flanges 120 and 120a of the girders 1 and 2 can be increased by forming the beam 10 so that the upper flanges 120 and 120a of the adjacent girders 1 and 2 And 120a, respectively, so that the upper plate can be formed.

According to another embodiment of the present invention, the beam forming part 200 may be formed in plural along the longitudinal direction of the girder 1. [

The fastening reinforcement 500 may be embedded in the transverse direction of the main body 100 and may extend toward the upper portion of the filling space forming groove 210 in order to facilitate coupling with the fastening means 510 and increase of the engaging portion (Fig. 13).

In this case, the fastening means 510 can be formed in an annular shape and can be inserted from the ends of the fastening reinforcing bars 500 formed on the fastening reinforcing bars 500 and the adjacent girders 2 to integrate the double fastening reinforcing bars 500 have.
