The present invention is easy and quick to place the vertical frame group for placing walls on the concrete floor surface with unevenness after pouring concrete side by side in a state where each base is arranged to the same level surface easily and quickly It is related to the tool used to make the vertical mold horizontal and the construction method to make it horizontal.

8 and 9, a conventional method for leveling the wall when constructing a wall casting mold on a concrete floor surface roughly shown is shown schematically.

Although the concrete floor surface F, as it is, is horizontally maintained as a whole of the floor surface, it is common that there are quite some irregularities.

As exaggerated in FIG. 8, the group of vertical molds 50 for placing walls on this uneven concrete floor surface F is arranged in the same order surface and placed side by side, Conventionally, the wooden wedge 51 and the wood piece 52 were used.

In this method, a plurality of wedges 51 having different height dimensions or inclination angles are made in advance in order to correspond to the degree of irregularities of the concrete floor surface that varies from place to place.

Also, in the construction site of the mold, as shown in FIG. 8, the level yarn used for leveling the display mark v at the same height position of one vertical mold 50 as necessary, and then leveling it. (w) is installed.

Then, the worker walks with a plurality of prepared wedges (51), while the marking mark (v) of the vertical frame (50) standing on the uneven concrete floor surface (F) is the level yarn (w) Check if there is a match.

Where the position of the marking mark v is lower than the level yarns w, the wedge 51 of the size corresponding to the shifted dimension is selected, or the wedge 51 or the neck piece of the size suitable for this at the work site. (52) and cut the wedge 51 between the bottom of the vertical mold 50 and the concrete floor surface F, until the mark mark (v) and the level yarn (w) coincide with each other. 50) was adopted to lift.

In addition, in a large space and the like, a complicated method of stacking and inserting a plurality of wedges 51 and a piece of wood 52 has also been adopted.

Alternatively, the vertical frame 50 is not directly placed on the concrete floor surface, but the vertically laid twigs on the floor surface are placed so as not to move, and the nails are fixed by fixing them, and a row is installed on the twigs. there was.

However, the above conventional methods have many difficulties as listed below.

(a) It takes a lot of effort and time to prepare several wedges or pieces of wood of various sizes.

(b) It takes effort and experience to select the best wedge or wood piece depending on the unevenness of the concrete surface.

(c) Since the contact surface between the vertical mold and the wedge is inclined, the space between the concrete floor and the bottom of the resin mold is opened by lifting the mold extra by this slope.

(d) Therefore, extra effort and time are required for the removal of the hardened concrete that flows out of this gap.

(e) Removing wedges or wood chips after concrete casting is cumbersome.

(f) It is almost impossible to reuse or recycle wood.

An object of the present invention is to make the vertical frame horizontal to make the work of laying the same level easily and quickly in the vertical frame group for placing walls and the like on the concrete floor surface with the unevenness removed. Provide the tooling and leveling techniques used.

Brackets used to make the vertical mold according to the present invention to the horizontal to achieve the above object, by arranging the vertical mold group for placing walls and the like on the concrete floor surface from which the irregularities are removed, The side-by-side excavation work is to be done easily and quickly, including post-working post-casting work. It was set as the structure provided with the main-body part 1 and the nail-shaped leg part 2 which protruded in the lower part of the main-body part 1.

And the nail-shaped leg part 2 was formed integrally with the main-body part 1 by seasoning process.

In addition, the vertical lower piece 3 is extended on one side of the main body 1, and the vertical lower piece 3 is nailed to face each other on the side of the remnant that becomes the base of the vertical mold. What is necessary is just to provide the hole 4.

In addition, the method of making it horizontal by the present invention includes a method of placing a remnant B on which a vertical mold is placed on a concrete floor surface in a vertical row along an installation line of a vertical mold group; A plurality of metal brackets (A) used to level the nail-shaped legs (2) on the lower side of the main body portion (1) on the plate piece of a size that can support the bottom of the vertical mold is prepared. The method of driving each nail-shaped leg part 2 on the upper surface of the remnant B at a narrower interval than the width dimension, and adjusting the degree of injecting the metal fittings A used to be horizontal, are adjusted. After the top surface was trimmed to the same level surface, a vertical mold was placed between these brackets in a sitting shape.

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

1 and 2 are shown as a perspective view, and a longitudinal cross-sectional view, viewed from the inside in the state in which the metal fitting A1 used for leveling this embodiment is horizontally collapsed laterally.

In addition, as a partial longitudinal sectional view, a state in which the present invention method is applied to the work of arranging and placing the group of vertical molds 50 for placing walls on the concrete floor surface F with irregularities in FIG. Indicated. 50a and 50b in the figure are the plywood panels constituting the vertical mold 50 and its reinforcement twigs.

The metal fitting A1 used to be horizontal is size enough to receive and support the bottom of the vertical mold 50. In this embodiment, the main body 1 on the plate piece of 60 mm x 40 mm angle and the lower side of the main body 1 are predetermined. Two nail-shaped legs 2A and 2B protruded at intervals, and a vertical lower surface 3 addressed on one side in the longitudinal direction of the main body.

The metal fitting A1 used to make this horizontal can be produced very efficiently only by punching and bending the rectangular metal plate 10 shown in FIG.

In other words, the main body portion 1, which occupies the right side portion of the folded gold e of the rectangular metal plate 10, is bent into a nail shape leg portion 2A on its left side. The cutout (a) which is almost V-shaped is provided, and it is set as the folded gold (b) between the both ends of this cutout (a). The pointed end of the cut (a) has a rounded shape for safety.

In addition, in the right part of the main body 1, an almost W-shaped cutout c is provided in order to bend and shape the nail-shaped leg 2B in a season shape, and the gold folded between both ends of the cutout c is provided. (d).

In addition, since both the cut portions (a) and (c) share the cut portions in the respective tip portions, the tip portion of the tip of the nail-shaped leg portion 2A is one nail-shaped leg portion 2B. The tip of the is divided into two.

Therefore, the nail hole 4 is provided near the lower end of the drooping piece 3 which serves as the fixing of the metal fitting A1 used to make it horizontal, and its reinforcing role.

Next, the effect | action of the said structure is demonstrated, referring FIG. 4, FIG.

First, the concrete floor surface (F) with the unevenness to which the mold is detached is subjected to the roughing of the required number of the remnants of a certain length in a vertical position in the vertical frame 50, and then nailed. Secure it to the floor.

In this state, the individual twigs B are inclined to some extent with respect to the horizontal plane X-X in accordance with the degree of irregularities of the concrete floor surface F, as shown in FIG.

Therefore, in this state, in which the vertical mold 50 groups are placed side by side in sequence, it is impossible to arrange and arrange each vertical mold 50 on the same level plane.

Therefore, according to the prior art, it is necessary to carry out horizontally relying on the level yarn w.

To do this, first, the level yarn w is laid at a position as low as possible by varying the top surface of the twigs B over the entire length of the groups of twigs B arranged in a columnar phase (not shown).

This is to minimize the gap g (see FIGS. 4 and 5) between the bottom surface of each vertical mold 50 and the twig B. FIG. It is preferable to suppress this clearance g to about 13 mm or less.

Next, the bracket A1, which is used to be horizontal on the upper surface of the vertical twig B, is temporarily arranged at a narrower interval than the width of the vertical mold 50. As shown in FIG. This is to be supported by two brackets (A1), (A1) used to level one vertical frame (50) horizontal.

This arrangement | positioning space should just be set to the space | interval suitable for the vertical frame 50 as long as it is a regular dimension.

After finishing the temporary arrangement or placing the brackets A1, which are used to be horizontal, at predetermined intervals, the brackets A1, which are used to be horizontal, are sequentially hammered into the upper surface of the twigs B by using a hammer. The nail-shaped legs (2A) and (2B) are nailed into the twigs (B) until the upper surface matches the level of the level yarn (w).

If the depth to insert the bracket (A1) used to be horizontal or too shallow, or the material of the remnant (B) is too light, when the concrete is placed, the weight of the bracket through the mounting bracket of the mold to the frame 50 Since it is transmitted, the nail-shaped legs 2A and 2B may get stuck in the remnant B by this weight.

In order to eliminate this concern, as shown in FIG. 4, the fixing nail 5 may be driven into the twig B through the nail hole 4 of the vertical piece 3.

This series of tasks do not require any skilled skills, and it is very simple and quick to make the top surface of the metal fitting A1 used to be horizontal.

And, as shown in FIG. 5, the upper surface of the bracket (A1) group, which is used to make the horizontal work after the work to be horizontal, is placed vertically in a row next to the frame 50, and then the necessary support storage process is performed. If done, the assembly of the concrete casting mold is completed.

If the vertical frame 50 is for pillar casting, it is not necessary to have a level thread, but the level is applied directly or across the tree between the brackets (A1) and (A1), which are used to make the two horizontal gaps narrow. You may perform the operation to make it horizontal.

Since the upper surface of the metal fittings A1 used to be horizontal in the stacked form of the mold is horizontal unlike the conventional wedge 51 (see FIG. 7), the bottom of the vertical mold 50 and the concrete floor surface F The gap g between the can be fixed to a minimum required of about 13 mm or less.

Therefore, when the concrete is injected into the mold, the aggregate also helps to prevent the gap g, and as in the prior art, there is almost no possibility that a large amount of concrete leaks from this gap g.

Therefore, the troublesome plucking of the leaked concrete mass required in the prior art is almost unnecessary.

In addition, even if the so-called cement mortar that does not contain aggregates enters the gap g and solidifies, this concrete, which is attached to the remnant B, remains unchanged when the vertical mold 50 and the remnant B are demolished. It comes off naturally together.

In FIG. 6, the metal fitting A2 used to make it horizontal in the 2nd Example was shown in the state which developed on the rectangular metal plate.

The difference from the first embodiment is that the shape of the nail leg portion 2A is slightly different.

FIG. 7 shows the bracket A3 used to level the third embodiment in a state where the rectangular metal plate is developed.

The difference from the first and second embodiments is that the nail-shaped legs 2A and 2B form a triangle.

Moreover, in the said structure, even if the detailed structure is changed suitably, the objective of this invention is achieved.

For example, the shape of the nail-shaped legs 2A and 2B is, of course, not limited to the illustration, and a shape that can be relatively easily driven into the twigs B while receiving the resistance to drive is adequate.

As is clear from the above description, according to the bracket and the construction method for leveling the vertical mold according to the present invention, various excellent effects in practical use as listed below can be obtained, Compared to the prior art using the wedge to reduce the cost of laying a wall or column, etc. can be significantly reduced.

(a) Brackets used to level them can be mass produced at very low cost.

(b) The leveling work can be done easily and quickly even by beginners.

(c) Much effort and time is required to prepare wedges of various sizes.

(d) The effort and experience to select the best wedge for each vertical mold is unnecessary according to the irregularities of the concrete surface.

(e) Workers do not have to walk around with bulky wedges.

(f) Since the gap between the concrete floor and the bottom of the vertical frame can be fixed to a minimum, troublesome work of extracting concrete spilled from this gap is almost unnecessary.

(g) The removal of wedges after concrete pouring is also unnecessary.
