Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a structure between a sheet pile attached to an H steel driven into soil, etc., and a formwork set at a predetermined distance from the sheet pile. This invention relates to a sheet pile fastener that integrally fixes the lower bottom part to the sheet pile to maintain a predetermined interval and further tightens and holds the formwork at the upper part when pouring concrete.

[Prior art] Conventionally, this type of fastener was
The one disclosed in No. 15964 was known. The device disclosed in Utility Model Publication No. 52-15964 has a connecting rod fixed to one piece of the L-shaped fitting almost perpendicularly to the other piece, and a leaf spring arranged parallel to the other piece of the L-shaped fitting. The leaf spring is formed by fixing one end of the leaf spring to one piece of the L-shaped fitting.

[Problems to be Solved by the Invention] The above-mentioned conventional fasteners are used in civil engineering work when installing formwork before pouring concrete. In order to prevent rotation of the separator and to integrally fix the stopper to the formwork, the separator and the connecting rod are manually fixed by welding or using screw locking material. This not only results in poor work efficiency, but also requires time and effort when installing the stoppers and adjusting the separator, which is made up of fully threaded bolts.In addition, when it rains or where there is water leakage, the stoppers cannot be used in the formwork. There was a problem that it was not possible to fix it.

The present invention has been made in view of this problem, and it is possible to securely fix the lower bottom of the board to the sheet pile attached to the H steel, and to adjust the screw insertion depth of all screw bolts by visually checking the scale. To provide a sheet pile fastening fitting capable of fixing a fully threaded bolt screwed to a predetermined depth so as not to rotate without using welding or a thread locking material.

[Means for Solving the Problems] In order to solve the above problems, the present invention enables the lower bottom of the board to be integrally fixed to the sheet pile attached to the H steel, and also provides a scale in the longitudinal direction of the board. The screw insertion depth of all screw bolts can be visually adjusted by displaying the screws, and the upper part of the board is bent into an inverted U shape to provide a connecting part, and the upper plate and lower plate of the connecting part are Screw holes into which all the screw bolts are screwed are formed on the vertical axis of the central part of the upper plate, and notches are provided on both ends of the upper plate on the horizontal axis of the upper plate with the screw holes projecting therein. By hitting the tip with a hammer etc., bend it from the weaker notch part,
It is configured to fit all the threaded bolts into the threaded holes of the upper plate and prevent the rotation of all the threaded bolts.

[Function] According to the present invention having the above configuration, the board is stably fixed to the sheet pile by the fixing plates protruding left and right from the center of the board, and the screw insertion depth of all threaded bolts can be accurately visually checked using the scale. It can be adjusted, and when the fully screwed bolt reaches a predetermined depth, the top end of the upper part of the connecting part is struck with a hammer, etc., and the upper plate is bent, and the screw hole in the upper plate is fully screwed. It bites into the bolt to prevent all threaded bolts from rotating.

[Example] An example of the implementation of the present invention will be described in detail with reference to the drawings. A base plate 2 is bent at right angles to one side of the lower bottom of a substrate 1 made of a rectangular steel plate, and A punching piece 3 is punched out into a rectangular shape from the lower bottom part of 1, leaving the bottom edge, and is bent to the other side so that it is flush with the base plate 2, and the base plate 2 and the punching piece 3 are used to fix a plate 4. A plurality of inverted peg holes 5 are bored in the fixed plate 4, and a scale 6 is displayed on one side of the substrate 1 above the punched piece 3 in the longitudinal direction.

Then, the upper part of the substrate 1 is bent to one side into an inverted U shape to provide a connecting part 9 having a horizontal upper plate 7 and a lower plate 8, and the upper plate 7 and the lower plate of the connecting part 9 are provided. Screw holes 10 and 11 are respectively drilled on the vertical axis of the central part of 8, and the screw hole 10 is drilled in the upper plate 7.
Notches 12 and 1 are provided at the edges of the upper plate 7 on both sides of the
2' is provided. In addition, the tip portion 13 of the upper plate 7
Although there is no need to specifically limit the angle, it is recommended that the angle be slightly tilted upward.

To explain the function of the embodiment, as shown in FIG.
After setting the sheet pile 15 on the
A barb nail 16 is driven into the barb nail hole 5 and fixed to the sheet pile 15 integrally. Then, a cap screw 1 into which the base end of the fully threaded bolt 17 can be screwed in from the base end side.
8, and a bolt 21 having a thread 20 around it is provided protruding from the center of the vertical tip surface 19 to form an adjustment tool 22. The proximal end is screwed in to tightly fix the proximal end surface to the end edge 18' of the cap screw 18, and the front end of the fully threaded bolt 17 is inserted into the screw holes 10, 11.
The depth of the screw insertion is adjusted by reading the position of the tip edge 17' of the fully threaded bolt 17 on the scale 6, and the sheet pile 15 is set in advance.
The width dimension of the poured concrete C from the base plate 2 and the length from the bottom of the base plate 2 to the tip end surface 19 of the adjuster 22 are made to match. Then, when these dimensions match, the tip end 13 of the connecting part 9 is struck with a hammer or the like to prevent the entire threaded bolt 17 from rotating again and its dimensions becoming out of order. Since the strength of the hole 10 portion is weakened, the plate 7 above the screw hole 10 portion bends, and the screw hole 10 portion bites strongly into the circumferential surface of the full thread bolt 17, preventing the full thread bolt 17 from rotating. The length from the bottom of the base plate 2 to the tip end surface 19 of the adjuster 22 is fixed. After that, attach the bolt 21 to the formwork 2.
3 to insert the inner wall of the formwork 23 into the adjusting tool 22.
By bringing the concrete C into close contact with the tip surface 19 of the concrete C, the casting width of the concrete C is automatically set. and,
The formwork 23 connects the vertical pipe material 24 and the horizontal pipe material 25 vertically and horizontally from the outside wall side, and also connects the horizontal pipe material 2
5 and is firmly fixed by screwing the bolt 21 which protrudes outside the formwork 23 into the front part of the home tie bolt 26.

After the casting width of the concrete C is set as described above, the concrete C is placed between the sheet pile 15 and the formwork 23.
After hardening, the home tie bolts 26, vertical pipe material 24, horizontal pipe material 25, and formwork 23 are removed, and the H steel 14 is pulled upward by a crane or the like.

[Effects of the Invention] Since the present invention is as described above, the base plate and the punched pieces each protrude left and right from the base plate to form the fixing plate, so that the fixing plate can be attached to the sheet pile by reverse-metal nails. When fixed using a screwdriver, it is firmly fixed with a sense of stability, and the screw insertion depth is adjusted by inserting all the screw bolts through each screw hole, visually checking the scale, and rotating the screws as appropriate.At the predetermined scale position, Once the fixed position of the fully threaded bolt is set, the upper plate is bent from the notch by simply hitting the tip of the upper plate with a hammer, etc., and the threaded hole bites into the fully threaded bolt, and the fully threaded bolt is fixed. It is securely fixed in that position without rotating, and then the formwork installation process can be started. There is no need for welding or the use of screw locking materials as in the past, and it can be used even during rain or water leakage. Since it can be installed easily, costs are low and the construction period can be shortened.
