DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor level used for forming a floor surface by leveling concrete poured on a deck material or a concrete panel at a building site of a building. Things.

[0002]

2. Description of the Related Art In a building such as a building, it is necessary to form a horizontal floor by forming a frame with a steel frame, arranging deck materials and folded plates, or laying concrete panels and pouring concrete on them. However, at this time, the floor is set as a guide for how much concrete should be poured from the deck material etc. and as a guide when leveling the poured concrete. Level. In the conventional floor level, a reinforcing bar is welded and fixed to a deck material or the like and is erected, and a vinyl tape is wound around a predetermined position of the reinforcing bar and a mark is used. Then, after pouring the concrete and leveling it, the reinforcing bar projecting upward from the concrete surface, which is the floor surface, is cut and removed.

[0003]

However, in the conventional floor level, it was necessary to fix the reinforcing bars by welding, so that there was a problem that the welding work was inevitably performed, and the installation required labor, time and cost. . Further, in the conventional floor level, since the reinforcing bar is vertically fixed to the deck material by welding, it is extremely dangerous if the reinforcing bar is tripped or joked. Further, the cabtire cable of the welding machine may be caught on the reinforcing bar welded first, which makes the operation difficult and inconvenient. In addition, the conventional floor level requires the work to cut and remove the reinforcing bar protruding from the concrete surface after the work is completed.
Not only was it inconvenient, but there was also the problem that traces of the cut portions remained on the floor.

In addition, since the conventional floor level requires welding, the place where the floor level is installed is limited.
There is also a problem that it cannot be attached to a place where welding is impossible, such as a concrete panel, limited to a place where welding is possible. Further, in the conventional floor level, when the concrete surface is leveled, a reinforcing bar projecting upward from the concrete surface hinders the work, resulting in poor workability. In general, before the work of pouring concrete, reinforcing bars are laid in a grid pattern.However, in the conventional floor level, it was necessary to weld the lower end of the reinforcing bars to deck material, etc. Before starting the work, it was necessary to set the floor level. Therefore, the set floor level hindered the arrangement work, and the workability was poor. The present invention has been made to solve these problems.

The projecting member 7 is temporarily fixed to the adjusting member 6 by forming a large-diameter portion 71 slightly larger than 3 and closely fitting the large-diameter portion 71 into the insertion hole 63 of the adjusting member 6. Note that the projecting member 7 is only temporarily fitted and temporarily fixed in the insertion hole 63 of the adjusting member 6, and by pressing the upper end of the projecting member 7 with a finger and pushing it down,
The protruding member 7 can be embedded in the insertion hole 63 of the adjustment member 6. It is desirable that the level member 61 be colored in a color similar to dry concrete. This is because after the concrete 9 is poured and the floor surface is formed, the upper surface of the level member 61 coincides with the horizontal surface 61a of the level member 61, and the upper surface 61a of the level member is exposed to the surface, so that the level member 61 is inconspicuous. .

Next, the use state of the floor level 1 of the present invention will be described. The floor level 1 of the present invention is used when building a flat floor by pouring concrete 9 after forming a frame with a steel frame in building construction or the like. In other words, how much concrete 9 should be poured from the deck material 8 etc., and it is installed as a guide when the concrete surface is leveled to make the floor horizontal and flat. Is used. Specifically, as shown in FIG. 3, the fitting portion 33 of the fixing member 3 is fitted and fixed to the convex portion 81 formed on the deck material 8 or the like.

The fitting of the floor level 1 to the deck material 8 is performed simply by pushing the fitting portion 33 of the fixing member 3 into the projection 81 of the deck material 8. Since the fitting portion 33 of the fixing member 3 is made of plastic or the like and can be slightly elastically deformed, it can be easily fitted by being pushed into the convex portion 81 of the deck material 8. Moreover, once fitted, the fitted portion 33 is restored to its original state,
Is securely fixed so that it does not come off during the work, but can be moved in the direction in which the projections 81 of the deck material 8 are formed (in FIG. 3, in the direction perpendicular to the plane of the drawing) by hitting with a hammer or the like. . Further, when it is desired to remove the fixing member 3 from the deck material 8, it is possible to push open the fitting portion 33 with a driver or the like.

Even after the floor level 1 is installed on the deck member 8, as shown in FIG.
It can be elastically deformed so as to bend in all directions, so that it is very safe even if an operator goes wrong or gets sick, and the receiving member 5 and the adjusting member 6 break and break. Never do. When the floor level 1 is installed, the bottom surface of the fitting portion 33 may be surely fixed to the deck member 8 or the like with an adhesive or a double-sided tape.

Next, the upper surface 61a of the level member 61 is adjusted to the height of the floor surface by moving the adjusting member 6 up and down with respect to the supporting member 2. FIG. 4 is a diagram showing a use state of the floor level 1 of this embodiment. As shown in this figure, to adjust the height of floor level 1,
For example, placing the bar member 14 such as a ruler on the level member 61, observing a mark attached to the bar member 14 from a predetermined point, and moving the adjusting member 6 up and down so that the mark is at a predetermined height. It is performed by At this time, the level member 61
The upper surface is a horizontal surface 61a, so that the bar member 14 can be easily placed thereon and the work can be easily performed.

After the height of the adjusting member 6 is adjusted, the lock nut 60 screwed to the adjusting member 6 so as to be able to advance and retreat is pressed against the upper end surface 52 of the receiving member 5 and tightened. The adjustment member 6 can be fixed with respect to 5. In general, a plurality of floor levels 1 are installed. For example, 32 floor levels 1 for 10 m × 20 m are installed and used, but the number of installations is determined on a case-by-case basis.

Next, concrete 9 is poured onto the deck material 8, but before that, a reinforcing work is generally performed on the deck material 8 so that reinforcing bars are stretched in a lattice shape. This reinforcing work is performed, for example, by providing reinforcing bars in a grid shape of 15 cm × 15 cm. When the floor level 1 is installed on the deck material 8, it is possible to install the floor member 1 in a state where the receiving member 5, the adjusting member 6, and the like are assembled on the fixing member 3. After placing the reinforcing member 8 on the deck material 8 and arranging reinforcing bars in a grid pattern on the upper part of the deck material 8 etc., the upper part from the elastic member 4 is installed on the fixing member 3 immediately before the concrete 9 is poured.

Also, when the concrete 9 is poured, the support member 2 is temporarily elastically deformed at the base end portion by the elastic member 4, but immediately restores to the original state. The concrete 9 can be poured without being buried, using the height of the level member 61 of the floor level 1 as a guide.

Even if the concrete 9 is poured into the upper surface 61a of the level member 61, the projecting member 7 projecting upward is provided at the tip of the adjusting member 6, so that the floor level 1 is not buried in the concrete 9, Therefore,
When leveling the poured concrete 9, it is possible to level the concrete 9 in accordance with the horizontal surface 61 a above the level member 61 while using the projecting member 7 as a mark. In addition, since the projecting member 7 is only temporarily temporarily fixed to the adjusting member 6, when the projecting member 7 is in the way when the concrete 9 is leveled, or when the concrete 9 is leveled. After the work done,
The protruding member 7 can be removed so as not to protrude from the floor surface by pushing the protruding member 7 into the adjustment member 6 with a finger. As a result, a floor surface or the like is formed, but only the horizontal surface 61a above the level member 61 is exposed on the concrete surface, and since the level member 61 is colored in dry concrete, the projecting member 7 is formed. After completion of the operation of removing the trace, almost no trace remains, and the finished state can be made extremely good.
