[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a joint forming jig for a foundation, and more particularly to an improvement in a joint forming jig for forming a joint at a joint between foundation beams constituting a foundation of a building. is there.

[0002]

2. Description of the Related Art In order to stably install a base and a floor of a building, a foundation is formed on the ground at a building construction site by using reinforced concrete or the like.

[0003] The applicant of the present application has further simplified the construction of a concrete foundation at such a construction site,
It has been proposed to manufacture a reinforced concrete foundation beam in advance and to construct a foundation part by arranging a plurality of such foundation beams in order to perform a quick operation.

FIG. 4 shows a configuration example of such a foundation beam.

[0005] As shown in the figure, the foundation beam 10 has a substantially rectangular parallelepiped shape, and is formed of concrete with a reinforcing bar inside. Recesses 12 are formed at both side ends of the foundation beam 10, and the foundation beams are formed by sequentially arranging the depressions so as to face each other.

The juxtaposed foundation beams 10 need to be connected and fixed to each other. FIG. 5 shows this fixing operation.

As shown in the figure, two foundation beams 10-1 and 10-2 are arranged side by side with a concave portion 12 facing them, and a reinforcing bar 14 is arranged in a space defined by the concave portions 12, 12. The concrete 16 flows into the portion and is solidified to connect the two foundation beams 10-1 and 10-2.

At this time, the two foundation beams 10-1, 10-
There is a gap at the joint between the two. Since the upper side in the installed state of the foundation beam 10 is exposed above the ground, the concrete 16 which has flowed into the joint between the two
If the water flows out onto the outer surface of the foundation beam 10 and solidifies, the aesthetic appearance of the foundation part is impaired. Therefore, as shown in FIG. 5, for example, a wooden member 18 or the like is loaded on the outer surface side of the joint portion of the
6 is effectively prevented from protruding outside.

That is, the concrete 16 flows in and solidifies while the wooden member 18 is loaded, thereby forming a concave portion, that is, a joint on the outer surface of the joint portion, thereby improving the appearance of the base portion.

[0010]

However, when the joint is formed by using the wooden member 18 or the like as described above, the wooden member 18 is inserted into the gap between the connecting portions between the foundation beams 10.
It is necessary to adjust the width, which impairs the speed of work. That is, the gaps between the foundation beams 10 are not always constant, but are installed with some deviation. Therefore, when the wooden member 18 having a constant width is always used, it is necessary to adjust the position of the foundation beam 10 and adjust the width of the wooden member 18 at the construction site, which hinders the speed of foundation construction. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide a slight displacement in the gap between the foundation beams arranged side by side to construct the foundation of a building. It is an object of the present invention to provide a joint forming jig for a base portion which can be easily compressed and inserted into the gap even when the joint is generated, and which can easily form the joint of the base portion.

[0012]

In order to achieve the above object, a joint forming jig for a foundation according to the present invention is connected to a plurality of foundation beams constituting a foundation by being juxtaposed on the ground at a building construction site. in joint formation jig base portion for forming a joint in parts, the basic Harima is Hama instrumentation in the gap, a loading unit formed of an elastic member ridge with a joint forming surface to the loading front end side, the loading unit of the joint-forming surface is fixed or integrated with the rear side facing, anda stopper portion having a flange portion is brought into contact with said foundation beam surface on both sides of the gap, the loading
The part is loaded by being compressed in the width direction of the gap,
It is characterized by being held between the foundation beams .

[0013]

[Action] When is positioned at a location facing the gap a loading unit basis Harima presses, loading unit themselves enters the gap by elastic deformation. The loading depth of the loading portion with respect to the gap is substantially uniquely determined when the flange portion of the stopper abuts on the surface of the foundation beam on both sides of the gap. For this reason, the joint formation surface on the loading tip side of the loading section can be formed at a substantially constant position in the entire area of the gap. That is, unlike the case where a wooden member or the like having no elasticity is loaded in the gap, the elastic member can always be easily loaded due to its elasticity without performing accurate width adjustment and position adjustment of the foundation beam itself. In particular, the loading part is compressed in the width direction of the
Is held between the foundation beams by the elastic force,
With that alone, the joint forming jig can be fixed in place.
it can. Therefore, the work of attaching the joint forming jig is further simplified.
Becomes

Since the flange portion is fixed to the loading portion, the work of compressing and loading the gap can be performed with the flange portion, which is an easier operation. Also, the work of removing the loading portion from the gap can be easily performed by holding the flange portion.

Then, concrete is caused to flow into the joint portion of the foundation beam in a state where the loading portion is loaded in the gap between the joint portions between the foundation beams, and after the concrete is solidified, the joint forming jig is removed. Joints are formed on the outer surface side of the joint portion of the beam. At this time,
The loading section compressed and loaded into the gap is
Because it adheres to the foundation beam, concrete flows from gaps
Outflow is reliably prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view showing the entire structure of a joint forming jig 20 for a base portion according to the embodiment.

As shown in the figure, the joint forming jig 20 is
2 and the loading portion 22 so as to function as the stopper portion.
And a flat plate portion 24 having flange portions 24a and 24b projecting more in the width direction. The loading portion 22 is formed of an elastic member such as a soft plastic or a soft rubber, for example, and has a hollow structure in which a cross-sectional shape is formed in a square shape and the inside is hollow. The surface of the loading section 22 on the loading tip side is, for example, a flat joint forming surface 22a.

The joint forming surface 22 of the loading section 22
A flat plate portion 24 is fixed to the back surface opposite to a. The flat plate portion 24 may be made of the same kind of material as the loading portion 22, but is preferably formed of a harder member such as hard plastic or hard rubber. That is, it is preferable that the flat plate portion 20 always maintain a stable shape,
On the other hand, the loading portion 22 can be easily deformed due to its elasticity and hollow structure. FIG. 2 is an explanatory diagram showing the operation of loading the joint forming jig 20 according to the above embodiment, and the base beam 1 is inserted into the gap between the connecting portions of the base beams 10-1 and 10-2.
0 is loaded from the outer surface side. in this case,
The operator grips the flat plate portion 24 and presses the loading portion 22 against the gap X, thereby performing the loading portion 2.
2 can be easily deformed and pushed into the gap portion X. Then, a flat plate portion 24 wider than the loading portion 22
At the position where the flange portions 24a, 24b at both ends contact the surface of the foundation beam 10, the loading operation of the loading portion 22 into the gap X ends. In this state, when concrete flows into the concave portions 12 and 12 of the foundation beams 10-1 and 10-2, the concrete is blocked by the tip end portion of the loaded portion 22 and solidified in that state. . Therefore, after the solidification, the joint forming jig 20 is gripped and removed from the flat plate portion 24, so that the joint, which is a concave portion, is formed at the joint portion. Since the joint has a flat joint formation surface 22a on the loading tip side of the loading section 20, the contact portion with the joint is solidified as a flat surface. Therefore, a joint having a good appearance can be easily formed without performing a complicated finishing operation only by removing the joint forming jig 20.

As described above, since the loading portion 22 has a resilient hollow structure, even if the gap between the foundation beams 10 is changed due to an error in the position setting, it can respond well, and it is extremely possible. As long as there is no large error, the compression loading into the gap X can be always performed stably.

Next, FIG. 3 shows the configuration of another embodiment.

The features of this embodiment are as follows.
It has a trapezoidal cross section having a tapered surface 22b on the front side toward the joint forming surface 22a, and has, for example, a V-shaped groove 24c opened on the back surface. And the V-shaped groove 24
c, the flat portions 24-1 and 24 projecting from both sides in the width direction.
-2 are fixed. That is, an interval is provided between the two flat plate portions 24-1 and 24-2.

The material of the loading portion 22 and the flat plate portion 24 in the embodiment of FIG. 3 is the same as that of the joint forming jig 20 shown in FIG. 1, for example.

The loading portion 22 formed with the V-shaped groove 24c has elasticity, and can be easily compressed and loaded by being pushed into the gap portion X of the foundation beam from the tip surface 22a side. it can. Further, since the outline shape is substantially trapezoidal, it is possible to appropriately cope with an installation position error of the foundation beam 10.

Further, as shown in FIG.
, The operation of pushing into the gap X can be made simpler. That is, the flat plate portion 24-
The wedge-shaped member 26 is inserted into the groove 24c between the first and 24-2 from the apex portion 26a side, and the wedge-shaped member 26 is pushed into the gap portion X side, so that the loading operation of the loading portion 22 is performed more easily. be able to.

After the inflow work and the solidification of the concrete after the loading, the joints 30 having good appearance are formed by grasping the flat portions 24-1 and 24-2 and removing the joint forming jig 30. .

It should be noted that the present invention is not limited to the configurations of the above embodiments, and various modifications can be made within the scope of the present invention. For example, the configuration of the loading portion that can be compression-loaded into the gap between the foundation beams is not limited to the above-described configuration, and the leading end surface on the loading side is formed as a joint formation surface, and the gap portion is formed. Various configurations are possible as long as they have elasticity that can be deformed according to the size. In each of the above embodiments, the loading portion 22 and the stopper portion 24 are formed as separate members. However, the loading portion 22 and the stopper portion 24 may be integrally formed. At this time, the loading portion 22 has a shape that is easily elastically deformed. It is preferable that the thickness has a relatively high rigidity.

[0028]

[Effects of the Invention] As described above, the joint forming jig of the foundation according to the present invention is provided with the gaps on the outer surface side of the foundation beams juxtaposed to construct the foundation of the building. Compression loading can be performed stably irrespective of slight fluctuations in the size of the gap. Since the loading and unloading operations can be easily performed, the joining operation of the juxtaposed foundation beams and the joint forming operation of the joints can be simplified and speeded up. Become.
