Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a building,
The present invention relates to a reinforcing bar assembling base used for assembling reinforcing bars of a foundation beam provided on the upper surface of abandoned concrete.

[0002]

2. Description of the Related Art Conventionally, a foundation for fixing a building to land and safely transmitting the weight of the building to the ground is based on a method in which concrete is thrown away on a gravel to be laid, and concrete is laid on the upper surface of the concrete. It is made by casting. The position and number of the reinforcing bars are determined so that the strength required for the building and the cover thickness, which is the size from the reinforcing bars to the concrete surface, are not less than the minimum size.

There are various types of foundations, and a solid foundation in which a foundation beam corresponding to a building beam is placed on the upper surface of abandoned concrete, a continuous footing foundation, and the like are generally used. For assembling these foundations, a rebar assembling stand shown in FIG. 8 is used. The rebar assembling gantry 1a has a base 2a, a cylindrical lower support 4b having a lower end fixed to the base 2a and standing upright, and is inserted into the lower support 4b, and can be adjusted vertically through an adjustment tool 4c. , And a reinforcing bar support member 6a fixed to the upper end of the upper support 4a and extending in the horizontal direction. This rebar assembling base 1a is for fixing and supporting the main reinforcement of the foundation beam with the reinforcement support member 6a in order to prevent the main reinforcement of the foundation beam from warping due to its own weight when assembling the reinforcement of the foundation beam. . The rebar assembled using the rebar assembling gantry 1a is installed at a position that sufficiently satisfies the strength and the cover thickness.

[0004]

However, the lower column of the conventional reinforcing bar assembling frame uses a cylindrical pipe into which the upper column can be inserted, resulting in high costs. Also,
The connection between the lower strut and the base must also be reinforced and rigid, which also increases costs. Furthermore, when the longitudinal direction of the upper support is welded in advance so as to be perpendicular to the longitudinal direction of the reinforcing bar supporting member, a plurality of members used for these reinforcing bar assembling stands are transported to the site by truck or the like. Is bulky and requires a large space for accommodating a truck bed, which is also a cause of high cost.

In view of the above points, an object of the present invention is to provide a rebar assembling gantry capable of reducing the manufacturing and construction costs of a reinforced assembling pedestal.

[0006]

According to the present invention, there is provided a plate-like base to which an adhesive is applied on the back surface and which is nailed to discarded concrete, a lower end fixed to the upper surface of the base, and which is perpendicular to the upper surface of the base. Two spurs standing upright,
A column made of a deformed reinforcing bar that is fixed while abutting a side surface to the splice bar, abuts a lower end on the base upper surface, and stands vertically above the base upper surface, and a column insertion into which the upper end of the column is inserted. A T-shaped kansashi receiver having a hole and a kansashi muscle insertion hole provided in a direction perpendicular to the strut insertion hole, and a kansashi muscle comprising a deformed reinforcing bar inserted into the kansashi muscle insertion hole. The gist of the rebar assembling stand is a feature.

A plurality of adjusting holes are formed at predetermined positions of the T-shaped kansashi receiver where the support column insertion holes are formed, and the height of the reinforcing bar assembling base may be finely adjusted. The gist is a rebar assembly base that can be assembled.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a rebar assembling gantry 1 according to the present embodiment has a plate-shaped base 2 and a lower end fixed to an upper surface of the base 2, and stands vertically from the upper surface of the base 2 to have a U-shaped upper end. The two reinforcing bars 3, 3 bent into a shape, a support 4 made of deformed reinforcing bars bound to the reinforcing bars 3, 3, a T-shaped kansashi receiver 5, and inserted into the kansashi receiver 5. And kansashi muscle 6.

Next, a procedure for assembling the rebar assembling base according to the present invention will be described with reference to FIGS. Figure 2 shows the base 2
FIG. 6 is a view showing a base member 7 on which attachment lines 3 and 3 are erected. When assembling the reinforcing bars, the back surface of the base 2 of the base member 7 is fixed by nailing on the discarded concrete. Before being nailed, an adhesive is applied to the back surface of the base 2 and placed on the discarded concrete. Because This adhesive has a function of preventing rust on the back surface of the base 2 in addition to the function of bonding the base 2 to the discarded concrete.

[0010] Then, as shown in FIG. 3, the support 4 is bound to the attachment bars 3, 3 using a wire or the like. The strut 4 used in this case is obtained by cutting a deformed reinforcing bar at a height corresponding to the arrangement position of the beam and using it as the strut 4, and is procured at a construction site. In addition, attachment line 3,3
Is vertically set in advance in the vertical direction with respect to the base 2, so that if the struts 4 are brought into contact with the side surfaces of the attachment lines 3, 3, the struts 4 are easily erected in the vertical direction with respect to the upper surface of the base 2. You can do it. It should be noted that the support 4 and the attachment 3,
3 may be bound at the site by winding the wire in multiple layers at the top and bottom,
May be welded to the contact surface.

After cutting the tip of the column 4 at a predetermined height for disposing the beam as described above, the tip of the column 4 is inserted into the column insertion hole 5a of the kansashi receiver 5, as shown in FIG. It is. The kansashi receiver 5 has a T-shape in which a kanseki streak insertion hole 5b is provided in a direction perpendicular to the support insertion hole 5a. Drilled holes 5c are provided. The adjustment position of the beam is finely adjusted by inserting the adjusting pin 5d into the perforated hole 5c.

Finally, as shown in FIG.
The kansius muscle 6 is inserted. The rivet streaks 6 project from the rivet streak insertion hole 5b of the kansashi receiver 5 in a direction in which the longitudinal direction is perpendicular to the longitudinal direction of the column 4, and the assembling of the reinforcing bar assembling 1 is completed. It is. The length of the kansashi bar 6 is set to be slightly longer than the length of the beam in the lateral direction, and the deformed reinforcing bar is cut on site and used as the kansashi bar 6.

Next, the manner of use of the rebar assembling stand according to the present invention will be described with reference to FIGS. First, as described above, a plurality of reinforcing bar assembling bases 1 are arranged at predetermined intervals so that the longitudinal directions of the kansashi bars 6 are parallel to each other, and the base 2 is applied to a predetermined position on the upper surface of the discarded concrete with an adhesive. And fix it with nails.

Then, as shown in FIG. 5, the two upper main bars 8a, 8a of the beam are placed at a predetermined interval from the kansashi muscle 6 in a direction perpendicular to the longitudinal direction of the kansashi muscle 6.
Next, as shown in FIG. 6, a plurality of stirrups 9, 9,... Bent in a quadrilateral shape are suspended from the upper main bars 8a, 8a at predetermined intervals. At this time, the plurality of stirrups 9 are suspended from the two upper main streaks 8a, 8a so that the positions of the hook portions 9a are alternately arranged. Will be located. Then, the contact portion between the upper main bar 8a, the stirrup and the stirrup 9 is bound by a wire. Finally,
As shown in FIG. 7, the two lower main bars 8b, 8b are inserted through the plurality of stirrups 9, 9,... And placed on the lower two corners of the stirrups 9, 9,. Stirrup 9,9
・ The parts that come into contact with are tied together with wires, and the assembly of the rebar is completed.
