Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure for fixing a concrete plate used when a concrete plate is used to form a fence or the like.

(Conventional Technique) Conventionally, when forming a fence etc. with concrete, a trench was formed in the ground, foundation concrete was poured into this trench, and reinforcement was placed on top of the foundation concrete after it hardened. A wall was formed by constructing a formwork and pouring concrete into the formwork.

However, this structure required a lot of on-site work such as reinforcing and forming formwork, making construction time-consuming.

Therefore, instead of pouring concrete on-site, a structure was proposed in which concrete plates manufactured at a pre-warming factory were embedded in the trenches on-site. In this structure, as shown in FIG. 13, a concrete plate 21 is installed in a groove 22, and the groove 22 is filled with a filler material 23 such as concrete. Alternatively, as shown in FIGS. 14 and 15, struts 24.25 made of H-shaped steel or square steel pipes are provided between the concrete plates 21, and the concrete plates 21 are supported by the struts 24.25. 21 and struts 24 and 25 are embedded in the groove 22.

[Problems to be Solved by the Invention] However, in a structure in which only the concrete plate 21 is embedded in the groove 22, the concrete plate 21 tends to tilt, making it difficult to vertically install the concrete plate 21. In addition, in a structure in which the concrete plate 21 is embedded together with the support column 24.25, by using the support column 24.25, the anchor installation work and the concrete plate 21 and the support column 24.2
5 and 11 had to be fixed by welding, requiring advanced technology and making construction difficult. In addition, the use of Apparent 24 and 25 resulted in high costs.

Therefore, an object of the present invention is to provide a structure for fixing a concrete plate, which can be easily constructed and can reduce costs.

(Means for Solving the Problems) The concrete plate fixing part structure of the present invention includes anchor members provided at the lower end of the concrete plate in a state protruding from the front and back sides of the concrete plate, and each end of the anchor part H The hole is provided with a hole into which a level adjustment bolt can be screwed.

[For production]

According to the configuration of this invention, under the concrete plate O(1;
Since the anchor member is provided protruding from the front and back sides i), the anchor member becomes an anchor when the lower end of the concrete plate is embedded in the groove, and the concrete plate can be reliably erected. Therefore, there is no need for additional supports to erect the concrete plates, so the work of joining the concrete plates and the supports can be omitted, and construction can be carried out efficiently. Furthermore, since no support columns are required, manufacturing costs can be reduced. In addition, a bolt hole is provided at the end of the anchor member through which a bolt for level adjustment can be inserted.
The inclination of the concrete plate can be corrected by adjusting the bolts screwed into the bolt holes. Therefore, the concrete plate can be vertically erected.

[Embodiment] An embodiment of the present invention will be described based on FIGS. 1 to 8.

The concrete plate 1 is formed by pasting together a pair of concrete members, as shown in FIG. A pair of female screw members (not shown) are embedded in the lower end surface of the concrete plate 1 at both ends, respectively, so that the anchor member 2 can be fixed with a fixing tool 11.

The anchor member 2 is made of channel steel, lightweight) M-shaped steel, and lip 't.
Consists of 14 section steel etc. In the center of the anchor member 2, there is a second
As shown in the figure, a pair of fastener insertion holes 2a are formed, and the anchor member 2 is fixed to the lower surface of the concrete plate l by inserting the fastener 11 into the fastener insertion holes 2a. There are fastener insertion holes 2 at both ends of the anchor part + A2.
b (Fig. 1) is formed, and this fixing tool insertion hole 2b
A bolt hole 3 serving as a bolt hole 3 is fixed to the inner surface of the bolt by welding.

A level adjustment bolt 4 (see Fig. 5) is screwed into this bolt hole 3. This bolt 4 has a shaft portion longer than the height of the anchor member 2.

In addition, in FIG. 3, this anchor member 2 is attached to a concrete plate 1.
FIG. 3 is a partial perspective view of a state in which it is fixed to the lower end surface of the holder.

The construction procedure of concrete 1-board 1 according to this example is explained in the fourth section.
This will be explained based on FIGS. 8 through 8. concrete board 1
An anchor member 2 is fixed to the lower surface of the holder.

A cracked stone 8 is laid on the bottom of the groove 7 formed in the ground, and a concrete 9 is placed on top of it (Fig. 4). After the waste concrete 9 hardens, the concrete plate 1 is placed (fifth
figure). In this state, the bolts 4 are screwed into one of the holes I to 3, and the inclination is corrected so that the concrete plate 1 is vertical (FIGS. 7 and 8). With the concrete plate 1 vertical, the groove 7 is filled with foundation concrete 10 (FIG. 6). With the above steps, the concrete plate 1 is erected.

According to the configuration of this embodiment, since the anchor member 2 is provided at the lower end of the concrete plate 1 so as to protrude from the front and back sides, the groove 7
The concrete plate 1 can be erected by simply embedding the lower end of the concrete plate 1 inside. Therefore, there is no need for a support post for erecting the concrete 1-1, and at the same time, no anchor bolts are required, and the number of parts and manufacturing costs can be reduced. Further, since no support columns are required, the work of joining the concrete plate 1 and the support columns by welding or the like can be omitted, and construction can be carried out efficiently. In addition, since a bolt hole 3 through which a level adjustment bolt 4 can be inserted is provided at the end of the anchor member 2, the bolt hole 3
By adjusting the bolt 4 screwed together by 31ilI, it is possible to correct the roughness of the 2I concrete cross 1.

Therefore, the concrete plate 1 can be easily erected vertically.

Another embodiment of the invention will be described based on FIGS. 9 and 10. In this example, as shown in FIG. 9, a notch 5a is provided at the center of both flanges of an anchor member 5 made of channel steel.
Anchor member A5 is fixed by fitting the corner of concrete I/board 1 into this notch 5a (FIG. 10).

According to the configuration of this embodiment, the anchor member 5 can be fixed to the bottom O of the concrete plate 1 by simply aligning the notch 5a of the anchor member 5 with the lower end of the concrete plate l and pressing it. , construction can be made easier. Other effects are the same as those of the previous embodiment.

Furthermore, there are other embodiments shown in FIGS. 11 and 12-1. In this example, as shown in FIG. 11, an anchor member 6 is formed by bending a steel bar at right angles, a nut as a bolt hole 3 is welded and fixed to the tip of the horizontal part of this anchor part +A6, and the anchor member 6 is The vertical part of the concrete plate 1 is embedded in a pilot hole (not shown) formed in the lower end surface of the concrete plate 1 (FIG. 12). According to the configuration of this embodiment, the size of the anchor member 6 can be reduced, making it easy to transport. Other effects are the same as those of the previous embodiment.

In the embodiment described above, a nut is fixed to the anchor member 25 as a bolt hole 3, but the bolt hole 3 may be formed directly in the anchor members 2 and 5 without providing a nut.

[Effects of the Invention] According to the concrete plate fixing part structure of the present invention, the anchor member is provided at the lower end of the concrete plate so as to protrude from the front and back sides, so that the anchor member can be inserted into the gap where the lower end of the concrete plate is embedded in the groove. serves as an anchor, allowing the concrete plate to be erected securely. Therefore, since no support is required to erect the concrete plate, the work of joining the concrete plate and the support can be omitted, and construction can be carried out efficiently. In addition, since no support columns are required, manufacturing costs can be reduced. In addition, a bolt hole is provided at the end of the anchor member through which a bolt for adjustment can be inserted, so by adjusting the bolt screwed into the bolt hole, it is possible to correct Therefore, concrete plates can be erected vertically.
