DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam rebar pre-installation facility for pre-assembling beam rebars on the ground.

[0002]

2. Description of the Related Art The pre-assembly method of rebar construction is a method of assembling rebars in advance at a processing site on the site or on the ground, and then transporting the rebars with a crane or the like.
In this pre-assembly method, for example, the following beam rebar pre-assembly equipment is used. The beam rebar pre-assembly facility is a facility for pre-assembly of beam rebars on the ground, and arranges a main rebar holding section for temporarily placing the main rebar, a main rebar supplied from the main rebar retaining section, and a stirrup temporarily placed. And an assembling section for performing assembly. The main bar holding unit and the assembling unit are installed at predetermined intervals (set based on the length of the main bar). A roller capable of feeding the main bar in the longitudinal direction (axial direction) is attached to the main bar holding unit and the assembling unit, so that the main bar of the main bar holding unit is horizontally moved to the single assembling unit by the roller. It has become.

[0003]

However, in the above-mentioned conventional beam rebar pre-assembly equipment, as shown in FIG. 8, a plurality of main reinforcing bars 3,... Was sent to the assembly department,
Due to the load of the plurality of main bars 3 placed on the roller 40, the rotation of the roller 40 is locked, and a large pressing force is required to feed the main bar 3. As a result, the work efficiency of the rebar construction has decreased, and the construction period has been prolonged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to increase the work efficiency of assembling a beam rebar and shorten the construction period. The purpose is to provide equipment.

[0005]

According to an aspect of the present invention, there is provided a main bar holding portion capable of holding a plurality of main bars in a horizontal state, and holding a plurality of stirrups in a bundle. Possible, and with these stirrups,
An assembly part capable of assembling a beam rebar by arranging the main rebar supplied from the main rebar holding part at a predetermined position, and a beam rebar pre-assembly facility comprising: A roller that can be sent in the direction is detachably attached to the main bar holding unit and the assembling unit, and the main bar of the main bar holding unit can be horizontally moved to the assembling unit via the roller.

According to the first aspect of the present invention, the main bars of the main bar holding portion are sent out one by one in the longitudinal direction by a roller detachably attached to the main bar holding portion and the assembling portion. It is moved horizontally to the assembly section. Therefore,
When the main reinforcement of the main reinforcement is horizontally moved to the assembly unit, the load applied to the roller is only the load of one main reinforcement placed on the roller, and the rotation of the roller becomes easy,
Therefore, it is possible to rotate the roller with a small pressing force and to send out the main reinforcement as compared with a case where a plurality of main reinforcements are placed on one roller as in the related art. As a result, the labor required to move the main reinforcement is reduced, and the work efficiency of beam rebar assembly can be increased. Accordingly, the construction period can be shortened. Also, since the roller is detachably attached to the main bar holding section and the assembly section,
When the main bar is moved from the main bar holding unit to the assembling unit, the mounting position of the roller can be adjusted according to the position where the main bar is temporarily placed. Thereby, the number of rollers to be installed can be reduced.

[0007] Here, for example, the main bar holding portion and the assembling portion are arranged to face each other in the longitudinal direction of the main bar, and the interval between the main bar holding portion and the assembling portion is set to be shorter than the length of the main bar. Through this, the main reinforcement of the main reinforcement holding portion can be moved horizontally to the assembly portion.

According to a second aspect of the present invention, in the beam rebar pre-assembly equipment of the first aspect, the roller is provided with a locking portion capable of locking a main reinforcing bar on the roller from both sides thereof. And

According to the second aspect of the present invention, since the roller is provided with the locking portion capable of locking the main bar on the roller from both sides thereof, for example, the main bar is assembled from the main bar holding portion. When moving to the section, it is possible to reduce the problem that the main bar rolls off the roller.

According to a third aspect of the present invention, in the beam rebar pre-assembly equipment of the second aspect, the locking portion is held in a rotatable state, and by rotating the locking portion, the locking portion is mounted on the roller. Of the main muscle can be released.

According to the third aspect of the invention, the locking portion is held in a rotatable state, and by rotating the locking portion, the locking to the main muscle on the roller can be released. Therefore, when the locking portion is rotated to release the locking of the main muscle on the roller, for example, when the main muscle is lowered from the roller, the main muscle can be easily lowered from the roller.

Therefore, when the main reinforcement of the main reinforcement holding portion is horizontally moved to the assembly portion, the load applied to the roller is only the load of one main reinforcement placed on the roller, and the roller can be easily rotated. In contrast to the conventional case where a plurality of main reinforcements are placed on one roller, the main reinforcements can be sent out by rotating the rollers with a small pressing force. As a result, the labor required to move the main reinforcement is reduced, and the work efficiency of beam rebar assembly can be increased. Accordingly, the construction period can be shortened. Further, since the roller is detachably attached to the main bar holding unit and the assembling unit, when the main bar is moved from the main bar holding unit to the assembling unit, the roller is moved according to the position where the main bar is temporarily placed. Can be adjusted. Thereby, the number of rollers to be installed can be reduced.

According to the second aspect of the present invention, since the roller is provided with the locking portion capable of locking the main bar on the roller from both sides thereof, for example, the main bar is moved from the main bar holding portion to the assembly portion. In the case where the main bar is moved, the problem that the main bar rolls off the roller can be reduced.

According to the third aspect of the invention, the locking portion is
It is held in a rotatable state, and by rotating the lock, the locking of the main muscle on the roller can be released.For example, when the main muscle is lowered from the roller, the locking portion is rotated. If the locking of the main muscle on the roller is released, the main muscle can be easily lowered from the roller.
