Description

TECHNICAL FIELD [0001] The present invention relates to a temporary bridge using a main head bracket and a method of constructing the same,

The present invention relates to a hypothetical bridge using a main head bracket and a construction method thereof. More concretely, the main head brackets are used to connect the two rows of files with one file on each row in the longitudinal direction, but the structure is simple because it does not use the truss member, the construction is excellent, And a construction method thereof.

FIG. 1A shows an attempt to construct a conventional hypothetical bridge.

That is, one file in which three files are installed is constructed as a two-file file,

The upper portion of the files is connected to each other by the truss member 18 to serve as a vent,

On the upper surface of the double row file 10, a transverse beam 11 is extended,

On the upper surface of the lateral beam 11, there is provided a girder 12 extending in the longitudinal direction and spaced apart in the lateral direction,

A temporary bridge on which a louver plate 13 is installed is shown on the upper surface of the girder 12. [

In the case of a temporary bridge, it can be said that the substructure is constructed by the two-row file (10) and the truss member (18). However, since the number of the installed files per one row becomes long and the air becomes long and the disassembly is not easy, There is a limit.

FIG. 1B shows an attempt to construct a conventional hypothetical bridge.

That is, a plurality of one-column files, in which two files are installed, rather than two-column files, are vertically spaced apart,

The head bracket 20 is inserted into the head of the file 10,

A transverse beam 11 is provided on the upper surface of the both-head bracket 20,

The two-head bracket 20 supports the load of the girder 12 by the radial support beam 14,

It can be seen that the truss member 18 is installed as a horizontal and inclined channel member between one row of files and between the girder 12 and the file 10.

Thus, by installing two files per column, it is possible to reduce the number of installation of the piles 10 relatively and to have the girder 12 supported by the head bracket 20, do.

As a result, it can be seen that the conventional construction of the temporary bridge is constructed by designing the pile, the head bracket, and the truss member so as to reduce the number of installed files per row, but also to install the temporary bridge between the long sides.

However, the number of pile construction per one column is large and the truss member is excessively used to cause construction and air delay, and as the number of pile construction increases, it is difficult to recover the pile.

Therefore, the present invention can be applied to the construction of a lower structure of a temporary bridge by using a pile and a transverse beam, while maximizing the lateral support performance of a pile head bracket so as not to install a separate truss member, It is possible to maximize the file support performance by restricting the files in two directions in two rows with the minimum number of file installations and solve the provision of the temporary bridge using the main head bracket which is more efficient, economical and quick construction and its construction method. This is a technical problem to be solved.

It can be seen that even one file 110 is effective for stably supporting the horizontal beams.

In addition, since a number of conventional truss members that directly connect the pile 110 and the transverse beam 140 are not required, the field work is significantly reduced, the work of machining the pile 110 is almost unnecessary, The pile construction is completed simply by assembling the support member 121 to the pile head bracket 120 in advance and inserting the pile into the head of the pile 110 to fix it.

At this time, longitudinal connecting beams 130 are provided between the pile head brackets 120 to constrain the longitudinally adjacent files 110 and the longitudinal pile 110, It becomes possible to have a dispersion effect.

2A and 2B, the lateral beam 140 is fixed to the upper surface of the pile head bracket 120 and the upper surface of the inclined support member 121 to use a steel frame member extending in the transverse direction, The member 121 uses an H-shaped steel frame member, and the lateral beam 140 uses two H-shaped steel members connected in parallel in order to secure lateral bending rigidity.

On the upper surface of the transverse beam 140, the girders 150 are extended in the longitudinal direction as shown in FIGS. 2A, 2B, and 2C, And they are constrained to each other.

As a result, the two transverse beams 140 and the longitudinal connecting beams 130 are formed in an H-shape when viewed in plan, thereby forming an effective dispersed support shape of the girder 150. [

The girder 150 is a steel frame member installed on the upper surface of the horizontal beam 140 so as to extend in the longitudinal direction,

First, the files 110 are installed in two rows on the ground, one file 110 is installed on one row, and the same is installed on the same longitudinal axis line.

The file 110 is constructed using a steel pipe file, but the installation position and the number of the two-row file are determined according to the longitudinal extension length of the temporary bridge.

Next, the file head brackets 120 are fixedly installed by inserting the file head brackets 120, which have been seen in front of the head of each of the files 210 of the two-column files, from the upper side downward (S120)
