Description

[Detailed description of the invention] [Industrial application field] This invention is an installation plate for foundation work that can be placed on the ground etc. in order to install foundation members in a horizontal state when performing foundation work for a building. It is related to.

[Prior art and problems to be solved by the invention] In the foundation work of a building, in order to install a foundation member called a precast foundation on mortar spread on the ground at a predetermined height and in a horizontal state, There is one in which a flat installation plate is placed on the mortar in advance, and the foundation member is placed and fixed on the installation plate. In this foundation work, it is necessary to place the installation plate horizontally on the mortar, but the installation plate itself is not equipped with a mechanism to display its levelness. Therefore, in the past, a separate spirit level was placed on the same installation plate, and this was used to check the inclination of the installation plate at multiple points, and then a hammer etc. was used to make sure that the installation plate was level. I was hitting it to correct the tilt.

Therefore, each time the mounting plate is placed on the mortar, it is not only necessary to prepare a spirit level and adjust the mounting plate so that it is level, but also to perform the adjustment work at multiple locations on the mounting plate. There was a problem. Another problem was that the spirit level had to be cleaned up after use, which was troublesome.

The purpose of this invention is to not only be able to install it at a predetermined height based on height adjustment stakes driven into the ground, but also to be able to adjust its own levelness without having to separately prepare or clean up a spirit level. An object of the present invention is to provide an installation plate for foundation construction that allows easy visual recognition of the construction.

[Means for solving the problem] Therefore, in order to achieve the above object, the present invention provides a plate-shaped base material with a pile insertion hole into which a height adjustment pile driven into the ground is inserted, The gist is a foundation construction installation plate in which the upper surface of the base material is formed flat, and an annular storage groove capable of storing liquid is formed around the pile insertion hole on the upper surface.

[Operation] Place the installation plate on the ground, etc. so that the pile driven into the ground is inserted into the pile insertion hole, align the top surface of the installation plate with the top end of the pile, and adjust the installation plate to the specified height. do. Then, the liquid is poured into the storage groove and the recess, and the liquid level in the storage groove and the upper surface of the base material are visually observed. At this time, the liquid level is always horizontal due to the characteristics of the liquid. Further, the upper surface of the base material is formed flat. Therefore, if the base material is placed horizontally on the ground or the like, the distance of the liquid level from the top surface of the base material will be the same at any part of the storage groove.
Furthermore, if the base material is not placed horizontally on the ground or the like, that is, if the base material is tilted, the distance of the liquid level from the top surface of the base material will vary depending on the location of the storage groove. Therefore, by looking at the distance of the liquid level from the top surface of the base material, it is possible to grasp the inclination of the base material.

[Example] Hereinafter, an example embodying the present invention will be described based on the drawings.

As shown in FIG. 1, a base material 1 constituting the installation plate of this embodiment is formed of concrete into a substantially square plate shape, and a plurality of reinforcing bars (not shown) are buried within the base material 1. . The upper surface 1a of the base material 1 is formed flat. A pair of notches 2 are formed in the center of the opposing sides 1c of the base material 1, and when lifting or installing the base material 1 of this embodiment, a lifting tool, a hand, etc. It is now possible to insert

Each corner of the upper surface 1a of the base material 1 on which a precast foundation member P etc. to be described later is placed has a V-shape in plan view and a V-shaped cross section as shown in FIGS. 2 and 7.
A pair of grooves 3 having a letter shape are buried therein. In this embodiment, these pair of grooves 3 are arranged at the top 3 of one groove 3.
a is formed so as to be close to the top 3a of the other groove 3. Therefore, when the precast foundation member P, etc. is not placed at the appropriate position on the base material 1, it is possible to shift the precast foundation member P, etc. to the appropriate position by applying a crowbar B, etc. to these grooves 3. It is becoming.

As shown in FIG. 1, a pile insertion hole 4 is provided in the center of the base material 1, the diameter of which increases toward the lower surface 1b. As shown in FIG. 9, this pile insertion hole 4 is formed in a size into which a height adjustment pile 9 driven into the ground G to determine the height of the base material 1 is inserted.

Further, as shown in FIGS. 1 and 6, on the upper surface 1a of the base material 1, around the pile insertion hole 4, a storage groove 5 into which water L as a liquid can be inserted is provided. This housing groove 5 is composed of four side portions 5a, and has an approximately regular square ring shape as a whole. Then, as shown in FIG. 2, the upper surface 1 of the base material 1 is
A is provided with four recesses 6 that communicate with the housing groove 5. Each recess 6 extends linearly from a corner 5b between adjacent sides 5a of the housing groove 5 toward the center of each side surface 1c, 1d of the base material 1. Therefore, the four recesses 6
are provided at equal angles (90°) with the accommodation groove 5 as the center. Therefore, the pile insertion hole 4
Assuming planes X and Y passing through the center O of , the accommodation groove 5 and the recess 6 are line symmetrical with respect to the same planes X and Y. Note that these recesses 6 are formed to have the same depth as the accommodation groove 5, and the water L in the accommodation groove 5 can flow in and out.

As shown in FIG. 5, on the lower surface 1b of the base material 1, from a side surface 1d different from the side surface 1c on which the notch 2 is formed, four locking grooves 8 are arranged parallel to each other toward the opposing side surface 1d. When the base material 1 is placed on the mortar M etc. spread on the ground G, the mortar M etc. can enter.

Although FIG. 3 shows the right side of the installation plate A constructed as described above, the left side is also formed in the same shape. Further, although FIG. 4 shows the front side of the installation plate A, the back side is also formed in the same shape.

Next, the operation and effect when performing foundation work using the installation plate A of this embodiment will be explained.

First, as shown in FIG. 8, mortar M is spread on the ground G at a construction site, and height adjustment piles 9 are driven into predetermined locations. This pile 9 has a pile main body 10 having a male screw 10a screwed on the outer periphery of the upper end.
and a nut 11 screwed onto the male thread 10a, and the upper end surface of the nut 11 is the reference height. Therefore, after driving the pile 9, the nut 11 is rotated with a spanner 13 to determine the reference height. This work of determining the reference height can be easily done by looking at the scale 12 displayed on the spanner 13.

After determining the height of the pile 9, the nut 11
Remove spanner 13 from. At this time, the nut 11 portion protrudes from the mortar M. continue,
The installation plate A is placed on the mortar M so that the nut 11 of the pile 9 is located approximately at the center of the pile insertion hole 4. Then, the upper surface 1 of the base material 1 constituting the installation plate A
Hit a with a mallet or the like to make the upper surface 1a and the nut 1
Determine the height of the installation plate A so that it is almost flush with the upper end surface of the mounting plate A.

Next, water L is poured into the accommodation groove 5 and the recess 6 .
At this time, for example, if the installation plate A is tilted and its right side is lower than its left side with respect to the horizontal plane C as shown in Fig. 6, the water L will flow from the left side to the right side. Then, the water surface of the water L in the receiving groove 5 and the recessed portion 6 and the upper surface 1a of the installation plate A are visually observed. At this time, the water surface of the water L is always horizontal. Also, the upper surface 1a of the installation plate A is formed flat. Therefore, if the installation plate A is placed horizontally on the mortar M, the distance from the upper surface 1a to the water surface will be the same at any part of the receiving groove 5 and the recessed portion 6.
Furthermore, if the mounting plate A is not placed horizontally on the mortar M, that is, if the mounting plate A is tilted, the distance from the top surface 1a to the water surface will differ depending on the location of the accommodation groove 5 and the recessed portion 6. Therefore, it is possible to grasp the inclination of the mounting plate A by looking at the distance of the water surface from the top surface 1a. Therefore, the horizontality of the mounting plate A is adjusted by hitting the left side portion of the mounting plate A with a mallet or the like, where the distance of the water surface from the top surface 1a of the mounting plate A is the same in all locations of the accommodation groove 5 and the recessed portion 6. After adjusting the horizontality in these left and right directions,
The horizontality in the direction perpendicular to the above direction is also adjusted in the same manner as above.

In this embodiment, the accommodation groove 5 is formed into a rectangular ring shape, and a recess 6 is provided extending from each corner portion 5b toward each side surface 1c, 1d of the base material 1 constituting the installation plate. By simply injecting water L into the recess 6, the inclination of the installation plate A can be seen at once in the left-right direction and in the direction perpendicular thereto. Therefore, unlike the conventional method, the troublesome work of preparing a spirit level and placing it at multiple locations on the installation plate A is no longer necessary. Further, there is no need to put away the spirit level after mounting the installation plate A.

In this way, the installation plate A is brought to a predetermined height and in a horizontal state, and when the mortar M at the bottom of the installation plate A has hardened, a precast foundation is placed on the upper surface 1a of the base material 1, as shown in FIG. Place the member P. At this time, if the precast foundation member P is not placed on the upper surface 1a of the base material 1 in an appropriate position, a crowbar B is applied to the groove 3 as shown in FIG. can be moved to position. Then, the height of the precast base member P is adjusted by rotating the bolt 14 attached to the precast base member P.

By the way, since a locking groove 8 is formed on the lower surface 1b of the base material 1 of the installation plate A, when the installation plate A is placed on the mortar M, the mortar M enters into the locking groove 8. . Therefore, after the mortar M has hardened, movement of the installation plate A in the horizontal direction is restricted, and the installation plate A does not shift.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and can be modified and embodied as desired without departing from the spirit of the invention, for example, as described below.

(1) In the above embodiment, the base material 1 is formed into a square plate shape, but it may be formed into a flat plate shape having any shape such as a disk shape or a hexagonal plate shape.

(2) The shape of the housing groove 5 is not limited as long as it is annular, and may be changed to, for example, a circular ring shape, a regular polygonal ring shape, such as a regular hexagonal ring shape.

(3) The shape of the recess 6 is not limited to that of the embodiment described above, and can be changed as appropriate. Furthermore, the recesses 6 may be omitted or the number of recesses 6 may be changed to other than four.

[Effects of the invention] As detailed above, the installation plate of the invention not only can be installed at a predetermined height based on the height adjustment stakes driven into the ground, but also requires the separate preparation of a spirit level. This has the effect that the levelness of the installation plate can be easily checked visually without having to clean up or clean up.
