Description

[Detailed description of the invention] This invention relates to a prefabricated channel-shaped fence culvert for constructing irrigation channels and drainage channels.

Next, this invention will be explained in detail using illustrated examples.

Figures 1 to 5 show an embodiment of this invention, in which a pair of left and right H-beam vertical frame rods each have a locking groove 1 that opens in the front and rear and extends in the vertical direction. The lower end of the bottom frame rod 2 is cut at an angle of 45 degrees, and both ends of the bottom frame rod 3 made of H-shaped steel extending in the left-right direction are also cut at an angle of 45 degrees. The vertical frame rod 2 is attached to the section.
An inverted U-shaped steel channel frame 4 is constructed by abutting the diagonal sections of the lower ends and fixing them by welding.

A large number of groove-shaped frames 4 configured in this manner are arranged at predetermined intervals in the front and back direction in a groove excavated and formed in the ground, and the left and right sides of the bottom frame rod 3 are wider than the bottom frame rod 3. The platen 5 is removably fitted to the middle part of a steel master disk 5 having a longitudinal length larger than the flange width of the rod 3 so as not to move in the longitudinal direction. It has a movement prevention protrusion 7 that protrudes downward, and the protrusion 7 is inserted into the ground.

A large number of precast concrete earth stop plates 6 arranged to extend across vertical frame rods 2 adjacent in the front-back direction
The end portions of the vertical frame rods 2 are inserted into the locking grooves 1 of each vertical frame rod 2 by falling in order from above, and are engaged with the inner flanges of the vertical frame rods 2, and the earth and sand 8 are placed on the outside of the earth stop plate 6. It will be backfilled.

FIG. 5 shows a steel master 5, in which a horizontal steel plate 9
V-shaped steel protrusions 7 extending in the left-right direction on both front and rear sides of the lower surface are fixed by welding, and on the upper surface of the intermediate portion of the steel plate 9, a pair of The lower part of the steel plate locking piece 10 is fixed by welding.

6 to 8 show other examples of the steel master disk 5. In the case of FIG. 6, a large number of steel plates with an inverted trapezoid cross section extending in the left and right direction are provided on the lower surface of a horizontal steel plate 9. The protrusion 7 is fixed by welding, and in the case of Fig. 7, the front and back sides of a horizontal steel plate 9 are bent downward to form the protrusion 7, and in the case of Fig. 8, the protrusion 7 is formed by a horizontal steel plate 9. The left and right sides of the steel plate 9 are bent downward to form movement-preventing and reinforcing protrusions 11, and the other configurations are the same as in the case of FIG. 5.

Note that when implementing this invention, a steel section other than H section steel may be used as the bottom frame rod 3.

Further, the longitudinally intermediate portion of the bottom frame rod 2 may also be fitted and placed on the master disk 5 as described above.

According to this invention, a large number of steel channel frames 4 are arranged at intervals in the front-rear direction, and the left and right sides of the bottom frame rod 3 of the channel frames 4 are respectively connected to wide steel floor plates 5. The ends of the retaining plates 6, which are fitted and placed between a pair of locking pieces 10 provided in the middle of the vertical frame rods 2 and which extend across the vertical frame rods 2 adjacent to each other in the front-rear direction, are used to lock the vertical frame rods 2. By performing the simple operation of inserting and locking into the groove 1, the channel-type fence culvert for waterways can be assembled and installed easily and quickly. Since it is supported by a steel floor plate 5 with a wide area, even when the trench fence culvert is installed on relatively soft ground, the sinking of the trench frame 4 can be prevented or minimized, and the trench fence culvert can be installed on relatively soft ground. can be stably installed at a predetermined level, and since the channel frame 4 and master disc 5 are removably fitted, they can be transported and stored separately to avoid bulk. In addition, the bottom frame rod 3 can be correctly placed and held at a predetermined position on the master 5, and since the channel frame 4 is made of steel, it is extremely strong. is obtained.

[Brief explanation of the drawing]

Figures 1 to 5 show an embodiment of this invention, in which Figure 1 is a perspective view of a channel-shaped fence culvert, Figure 2 is a plan view showing a part of it, and Figure 3 is a groove-shaped fence culvert. FIG. 4 is a perspective view of the frame, FIG. 4 is a front view thereof, and FIG. 5 is a perspective view of the master. 6 to 8 are perspective views showing other examples of master discs. In the figure, 1 is a locking groove, 2 is a steel vertical frame rod, 3 is a steel bottom frame rod, 4 is a channel frame, 5 is a steel floor plate, 6 is a retaining plate, and 7 is a protrusion for preventing movement. 10 is a locking piece made of a steel plate, and 11 is a movement prevention and reinforcing protrusion.

Claims (1)

[Scope of utility model registration request] The lower end portions of a pair of left and right vertical steel frame rods 2 having locking grooves 1 opening in the front-rear direction are fixed to both ends of a steel bottom frame rod 3 extending in the left-right direction to form a steel channel frame 4. A large number of groove-shaped frames 4 configured in this manner are arranged at intervals in the front-rear direction, and the left and right sides of the bottom frame rod 3 are each made of steel and have a width wider than the width of the bottom frame rod 3. The end of the retaining plate 6, which is fitted and placed between a pair of locking pieces 10 provided in the middle part of the master disk 5 and extends across vertical frame rods 2 adjacent to each other in the front-rear direction, is connected to the locking piece 10. A channel-shaped fence culvert characterized by being inserted and locked in a stop groove 1.
