Description

[Detailed description of the invention] The present invention relates to structural members used in piling.

This m1cFX can be applied particularly to pilings with greater rigidity than conventional pilings, but the application is not limited to pilings with high rigidity.

In environments where pilings with greater rigidity than conventional sheet pilings are required, it is known to use pilings that are entirely or partially connected to hollow boxes when viewed from above. There is. Of the attached drawings, Figure 1A and Figure 1B are formed in whole or in part by such boxes.]
(This is a plan view of the pile pipe. OIC and 1drlA indicate the main structural members l and 2t that form the piling pipe in Figs. A fixing member 4 is shown.

As can be seen from FIG.
have. The lip 3 is formed during a hot rolling process in which the structural member is formed onto itself.

In order to create a horizontal lip on both edges, there must be a floating system of rolls, so the rolling of lip 3 is very far apart, and if such floating occurs even a little, the lip will no longer be horizontal. , the connection by the fixing member 4 becomes defective. Additionally, each specific roll configuration is required depending on the shape and size of the structural member. This greatly increases the cost of structural members and makes it uneconomical for manufacturers to produce structural members having a variety of sizes and shapes outside of a certain range. This, in turn, limits the extent to which this type of piling can be used.

Various other types of high-rigidity pilings are known, but they have drawbacks that are at least as great as the aforementioned pilings.

The wire of the invention has at least one longitudinal 7 langes.

A plurality of parts of the bolt located on the longitudinal edge of the #7 lunge and deformed with respect to the remaining surface of the #7 lunge, and a plurality of parts of the bolt that are alternately arranged and deformed with respect to the part of the bolt. An elongated structural member for use in piling structures, characterized in that the hook is comprised of a second plurality of parts deformed to different degrees. The table m "deformed in nine different degrees" shall mean not only deformation in nine different angles, but also deformation in the opposite direction.

As used herein, the term "7 lange" shall mean any free end portion that may be deformed as described above.

The present invention will be explained in more detail using Figure M'f below.

Figure 2 shows an I-shaped cross-section bar 5 having a pair of crimps 6m and 6b and an opposing pair of 7-turns 6c and 5d'l. As shown in 7 lunges 6c and 6d, the edges of these 7 lunges, the portions 7 that are deformed with respect to the rest of the 7 lunges, and the portions 7 that are arranged alternately with this and are undeformed or different from +S* It has been transformed! It has 8t-minutes.

In this figure, the portion 8 is not deformed. Hereinafter, for ease of reference, this deformed portion 7 will also be referred to as a crimp. This is because this part can best be shaped by a process similar to crimping.

Although the crimp is shown only on a portion of the 7 flange 6C and 64, it should be understood that it actually exists over the entire length of each of these 7 langes. It should be understood that if a crimp is required, there will be a crimp along the entire length of each of 5a and 6b. The angle of crimping, that is, the angle formed by the surfaces of parts 7 and 8, can be changed depending on one condition, but
It is convenient to set the angle between 15 and 45 degrees, and between 20 and 30 [
It is more preferable that The lengths of sections 7 and 8 can also vary, but it is convenient for each to be, for example, 25 to 100 m, more preferably s75wx+.

Considering the length of the transition between the crimped and uncrimped parts, the crimping pitch, i.e. the distance between the centers of adjacent crimped parts, should be between 1oo and 300m. preferable.

The crimp 7 is formed by cold working. Thus, the forming of the crimp is a separate process from the manufacturing process of the bar itself, and therefore any 7. 7 of bar material with lunges
They meet by forming on a lunge. Therefore, we offer crimp 6C in a wide variety of sizes and shapes to meet customer requirements.
It is a simple matter to construct shaped structural members.The versatility of the present invention will be discussed later with reference to several footwear piles that can be manufactured using the present invention.

The effect of crimp molding mentioned above is seen from the edge.

The edge of each 7-tsunji exhibits a wedge-like appearance that widens at the end. This is illustrated in FIG. The figure also shows a fixing member 9 for connecting and fixing the two flanges. These two 7-way bolts are shown to have different thicknesses for illustrative purposes. The 2 flange on the left side is thicker than the 7 lange on the right side, but normally the two 7 langes connected and fixed by the fixing member are considered to have the same thickness. However, this is not necessary.

The fixing member 9 has approximately H1t, the inner surfaces 101 and Xta of the two arms lO and 11 are approximately perpendicular to the horizontal bar 12,
Inner surfaces 13a and 141a of the remaining two arms 13 and 14
It is leaning towards O and IIK. Therefore, these □
The arms define a pair of slots that narrow outwardly. The strength of the crimp is sufficiently great to prevent the 7-lunge from being laterally pulled out of the fixed member, except in extreme cases such as driving into hard ground.

Figure 4 shows a crimped shaped bar 5 with nine flanges.
．． and a cross section of a piling consisting of the fixing member 9. This pile is a series of hollow boxes ais. Figure 4a is similar to Figure 4, but with I-bar 5
The difference is that the height of ' is large and that these are used alternately with T-shaped bars 5'. The structure of FIG. 41 uses less steel than the structure of FIG. 4, but has similar strength. The pile shown in Figure 5 is similar to that in Figure 4, but is curved. The ninth step in making such a pile ring is to cut 6a and 6 with a plasma cutter, for example, before making the 7 lunge 6M and 6b Kri IJ ring.
All you have to do is cut the edge of b. What is the vehicle radius of the pile made by K in this way?

, which includes right-angled corners.

As can be seen from this figure, such a pile ring can be made by forming crimps on the edges and using dead profiles 15 similar to those described above with respect to FIG. A chevron 15 forms the inside of the corner, and a profile 16 forms the outside.
formed by. Profile 16 has a middle part 17 and two outer parts 18, 18 forming an angle of 45 degrees with respect to 17. The edge K of the outer part 18 is made of chevron l! A crimp similar to s is molded.

The off-line diagram also shows one modification. This figure shows a fixing member 9' arranged in such a way as to enable the production of a pile having a surface which is substantially co-planar and within rM. The 7 flange, which is connected and fixed by the fixing member 9', has crimps 7' and 7' arranged alternately. 7' is the uncrimped portion 80 in FIG. The crimp 7' has a larger rimping angle than the crimp 7', so as to produce the wedge effect described above. As can be seen from Figures 8 and 8, the nine piles thus created form substantially coplanar surfaces. This is desirable in certain applications. An example of such an application is the wall of a sewage tank which is fitted with a one-turn agitator to agitate the contents of the tank and scrape sludge from the wall.

In such cases it is important that the wall from which the sludge is scraped is as smooth as possible, and w19 therefore satisfies this requirement.

FIG. 9 shows a nine-shaped bar 5 connected by a complete Larsen pile 20 and two half-Rusen piles 21 obtained by cutting the complete Larsen pile in the longitudinal direction. The connection is fixed with the Larsen interlock.

The half-length pile 21 is made of engineered zelkova wood 5 and their edges K.
It has a jlE shape and is connected and fixed by nine crimps and a fixing member 9.

The above description of the present invention is mainly directed to the production of high-rigidity pilings, but single-piece #1 can also be used for ordinary sheet pilings. Or this
FIG. 10, shown in FIGS. 1 and 11, shows a piling structure consisting of a plurality of structural members 22 that are angle irons with right-angled corners, with adjacent angle irons rotated 180 degrees relative to each other. A clean plate 23 is formed on the protruding end portion of the zero member 22. In the structure shown in Figure 10, the crimps are outwardly directed on both sides of the free end portion. This can be achieved by deforming the adjacent portions of the rim in opposite directions, for example by +15° and -15° as shown. The free end portions are shaped to match the shape of the crimping to be used and are connected and fixed by a fixing member 24.

Fig. 211 shows a pile structure similar to Fig. 10, except that a U-shaped groove member 25 is used instead of the chevron member.

Numerous other piling structures can be made by forming crimps on the edges of suitably toothed steel sections.

Figures 12 and 13 show a machine for deforming seven flanges of a profile to produce a structural member according to the invention.

This machine has a main frame 30 supporting a pair of hydraulic rams 31. A thrust transmission member 32 is attached to the lower end of each ram 31. Each thrust transmitting member 32 has a lower surface 33 that is part of a spherical surface, and 33 is a thrust receiver for member 35.
is pressing against the upper surface 34 of. Each thrust transmission member 32
are each surrounded by a collar 40 which serves to lift and retain the upper die holder 36 from the profile 5 when the hydraulic ram is retracted after crimping. As for the thrust receiver, the member 35 is attached to the upper part of the upper die type holder 36, and a pair of dies @37 are attached to 36. A pair of dice 1139 is attached to a pair of lower dice wave holders 38 facing the dice 36. Dice acid can be horizontally K11-noded on each holder. This is necessary for rounding to allow crimping of parts with varying widths and seven langouse thicknesses.

In crimp molding, the 7 runci 6'1 and 6b that are to be crimped are placed in opposing dies! 137. ! = 39, and by operating the hydraulic ram 31, the die 1137
Move and crimp dies 1137 and 39 6m and 6
b is retained for deformation. Then dice 513
7 is released and the profile 5 is moved and sent to the primary crimp forming position. -As an example.

In FIG. 12, a part of a shaped bar having crimps 6m and 6b on which crimps are formed as the profile 5 is shown.

As can be seen, this process can be sped up by dispensing multiple die layer pairs to simultaneously form multiple crimps on each of the seven lunges.
