Abstract

PURPOSE:To shorten the period of construction as well as to remove the difficulty of joining by a method in which a magnet and a magnetic the are built in the joint of concrete blocks, etc., for road to join them by the magnetic force. CONSTITUTION:A magnet plate and magnetic tape 4 are built in the joint of road concrete slabs, concrete tubes, street blocks, manhole covers for city water and sewage, flat plate blocks, etc., in such a way as to join them by the magnetic force. A magnet plate or tape 4 is built in the recession 3 formed on the joint face 2, and the concrete blocks, etc., are joined by using the magnet plate or tape 4 of different heights as needed. The concrete blocks, etc., can thus be simply joined with each other in a short time.

Description

[Detailed Description of the Invention] This invention relates to the main body joining surface, the main body receiving surface, and the main body joint of concrete products for roads, concrete pipes, street clearing materials, boxes, manholes for water and sewerage, covers, flat blocks, blocks, etc. The present invention relates to a magnetic joining joint in which a concave portion is provided on a surface thereof, and a magnet plate, a magnetic tape, etc. are incorporated into the concave portion to form an uneven portion, and the main body is joined to the concave portion.

The conventional joining method was to join the male and female bodies and connect the bodies using the tightening pressure of the bolts, but due to corrosion of the bolts, vibrations and pressure may cause the connecting parts to shift or the screw threads may be missing when tightening. The bolts or bolts will rust and the nuts won't turn. In the joint where the gasket is attached to the male and female parts, the joint is caused by the pressing pressure between the main bodies, so there may be misalignment due to pressure such as soft ground, vibration, earth pressure, etc., the gasket is cut, and the gasket is twisted during joining. There were disadvantages such as water leakage from joint surfaces due to failure to fill the mortar to the details, missing mortar, cracks, etc., and displacement of the body due to pressure.

The purpose of this invention is to connect and join the main bodies by joining using magnet plates and magnetic tape.

To explain this invention based on the drawings, FIG. 1 is a cross-sectional view showing a main body 1 having a recess 3 on the joint surface 2 side and a magnet plate and a magnetic tape 4 integrated into the recess 3. FIG. 2 shows a recess 3 provided on the joint surface 2 side of the main body 1.
FIG. 2 is a cross-sectional view of a main body 1 in which a magnetic plate and a magnetic tape 4 having high and low heights are integrated into the main body 1. FIG. FIG. 3 shows the concave portion 3 of the concrete pipe 5. FIG. 3 is a side cross-sectional view showing a magnet plate and magnetic tape 4 incorporated into the joint surface 2 of the insertion port corresponding to the convex portion 6. FIG. In FIG. 4, a magnet plate and a magnetic tape 4 are integrated into a recess 3 in a joint surface 2 on the side surface of a boundary block 7.

Figure 5 shows a magnet plate and magnetic tape 4 integrated into the concave part 3 of the joint surface 2 on the side surface of the L-shaped 8. Figure 6 shows a concave part 3 provided in the bottom part 9 of the L-shaped 8. A magnet plate and magnetic tape 4 were attached to the part and integrated. In FIG. 7, a magnet plate and a magnetic tape 4 are assembled into the recess 3 of the joint surface 2 of the O-shaped groove 10, and a magnet plate and the magnetic tape 4 are integrated into the recess 3 of the lid receiving part 11. In FIG. 8, a concave portion 3 is provided on the joint surface 2 of the diversion culvert 12, and a magnet plate and a magnetic tape 4 are incorporated and integrated. In FIG. 9, a concave portion 3 is provided on the upper surface 13 of the diversion culvert 12, a magnet plate and a magnetic tape 4 are assembled, and a lid 20, L-shaped 8, etc. which are integrated with the main body are mounted and integrated. 10th
In the figure, a magnet plate and a magnetic tape 4 are integrated into a lid receiving part 11 at a manhole slanted wall 14. FIG. 11 shows a manhole straight wall 15, and a recess 3 is provided in the joint surface 2 where the manhole slanted wall 14 and the manhole straight wall 15 are joined, and a magnet plate and a magnetic tape 4 are integrated into the recess 3. Although not shown, the same magnet plate and magnetic tape 4 as those of the manhole straight wall 15 are also attached to the bottom part 9 of the manhole slanted wall 14 in the recess 3.
It is connected and joined by incorporating it into the body and integrating it. 12th
The figure is a cross-sectional view of a manhole straight wall 15. A magnet plate and a magnetic tape 4 are housed in the recess 3 of the joint surface 2 and integrated, and the upper and lower bodies are connected and joined. Figure 13 shows the flat block 1
FIG. 14 shows how the magnet plate and magnetic tape 4 are integrated into the flat block 16 on the side surface 17 of the block 16. Incorporate and integrate 4. Figure 15 shows
A magnet plate and magnetic tape 4 are attached to the end of the bottom surface 9 of a road gutter cover 19 and integrated. Figure 16 is L
The opening 21 is open in the lid 20 of the type 8 and road gutter lid 18, and a magnet plate and a magnetic tape 4 are integrated into the recess 3.

The magnetic joining joint configured as described above joins the main bodies by magnetic force.

For the above reasons, the construction period can be shortened by easily joining the main bodies together.

As explained above, this invention includes a magnet plate in the recess of the main body,
The magnetic tape is integrated and the main body is connected and joined by magnetic force.
