Description

[Detailed description of the invention] Industrial application field This invention is particularly useful for parking lots, factories,
This relates to construction earthen floor joint supports used when embedding joint material that induces cracks due to expansion and contraction of concrete in the earthen floor of a warehouse or the like.

Conventional technology Until now, there were no suitable metal fittings of this type, so reinforcing bars were cut to the appropriate size and driven into the dirt floor.
Some types have iron joints integrally fixed to the upper side.

Another conventional construction method is one in which expansion joint material is supported and fixed with mortar.

Problems to be solved by the invention However, in the above-mentioned form, it is necessary to deal with each case on-site, which requires a great deal of labor and time, and is extremely impractical from a practical point of view due to poor construction accuracy.

Means to Solve the Problems This idea was devised in view of the problems of the past, and its purpose was to be able to reliably and easily support and fix various types of joint materials using pillars driven into the dirt floor, etc. An object of the present invention is to provide a construction dirt floor joint holder that has excellent functionality and workability, such as being able to be installed with high precision.

As a means for this purpose, a side U-shaped joint material receiving part is provided above the driving column having a suitable length and having a connecting part on the upper part, so that it can be moved at least up and down by a connecting shaft. .

Function: For example, place a dirt floor joint support bracket near the joint material and tap the head of the support to erect it on the dirt floor.

Next, place the joint material into the joint material receiving part and temporarily secure it with wing bolts.

After that, the joint material receiving part is moved up and down to adjust the thickness of the earthen floor slab, and then fixed again with butterfly bolts, which enables quick and reliable construction and solves the problems of the conventional product. .

Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a perspective view of a dirt floor joint receiving fitting according to a first embodiment of this invention.

1 is a dirt floor joint receiving metal fitting.

2 is a round bar-shaped driving post with an appropriate length,
The tip is formed into a pointed shape, and a connecting portion 3 with a nut is integrally fixed to the upper side surface.

Reference numeral 4 denotes a joint material receiving part formed by bending a flat plate to form a U-shape on the side. Butterfly bolts 5, 5 are screwed into one side and both sides of the joint material so as to be able to move forward and backward in order to fix the joint material. .

Reference numeral 6 denotes a connecting shaft with a male thread, the upper end of which is integrally fixed to the center of the bottom surface of the joint material receiving part 4;
The lower part is screwed into the connecting part 3 of the driving column 2 so that it can move forward and backward in the vertical direction.

An example of use of the first embodiment of the dirt floor joint receiving fitting 1 according to the invention constructed as described above will be described below.

As shown in FIG. 2, the earthen floor joint receiving fitting 1 is set upright on the earthen floor D by hitting the head of the driving support 2 with a hammer or the like at the attachment position of the joint material A.

Subsequently, the joint material receiving portion 4 is adjusted to a required height using the connecting shaft 6.

Thereafter, the joint material (wooden joint) M is placed in the joint material receiving portion 4, and the wing bolts 5, 5 are fastened so that the top surface of the wood joint M matches the thickness of the concrete slab on the floor.
Support and fix it in place.

As described above, according to the earthen floor joint receiving fitting 1 of the first embodiment, the joint material M can be reliably supported and fixed by the driving column 1 driven into the earthen floor and the joint material receiving part 4, and also easily. Moreover, it has excellent functionality and workability, such as being able to be constructed with high precision, and is extremely effective in practice.

Next, another example of this invention will be explained.
FIG. 3 is a front view of the earthen floor joint holder according to the second embodiment. The earthen floor joint holder 21 is a flat plate bent into a Z shape and has a seat portion 23a at the bottom and a support portion with a long hole 23b1 at the top. The connecting shaft 6 is supported and fixed in the elongated hole 23b1 of the connecting portion 23 with a double nut 7 so as to be movable in the vertical and horizontal directions.

This also has the same effect as the first embodiment, and since the joint material receiver can be movably supported and fixed in the vertical and horizontal directions, the work efficiency can be further improved, and the seat part 23a This has the effect of preventing the driving column 2 from sinking.

Note that the joint material to be used is not limited to the above-mentioned wood joint material, but may be arbitrarily selected, such as iron joint material, a combination of expansion joint material and angle material, etc.

Moreover, it is preferable that the dirt floor joint receiving metal fittings be attached to the connection parts of the joint materials, and provided in a staggered manner along the joint material attachment axis.

Further, the joint material receiving portion in the above embodiment is not limited to the above shape, and can be easily deduced from this invention, such as a corner portion having openings in four directions.

Effects of the invention As explained in detail above, this invention enables the joint material to be reliably supported and fixed on the earthen floor, and can be easily and accurately constructed. This makes it possible to obtain an extremely effective earth joint bracket for construction.
