Description

  In the present invention, the horizontal direction (in the direction of arrow S in FIG. 4A, the same applies hereinafter) to the gap between the sound insulation plate built into the groove of the pillar made of H-shaped steel or the like (hereinafter sometimes simply referred to as a pillar) and the groove wall surface. )) The fixing plate for fixing the sound insulating plate to the groove wall surface of the support column, especially the bolt can be mechanically adjusted by screwing the bolts. The present invention belongs to the technical field of a sound insulating plate fixing bracket having a configuration in which there is no fear that a bolt will loosen even when subjected to repeated loads.

Sound insulation walls built along highways and other roads and railways, etc., along the edges of roads and tracks for the purpose of blocking or preventing the spread of noise generated during the driving of automobiles and rail vehicles. Long built.
These sound insulation walls are built with pillars at each position spaced along the edge of the road at a certain distance in the longitudinal direction. It is constructed by the method to do.
As a fixing bracket at that time, the sound insulating plate is usually fixed by using a fixing bracket excellent in the function of filling the gap between the U-shaped groove of the column and the sound insulating plate and firmly fixing the sound insulating plate to the column. Construction technology is known.

For example, the sound-proof wall stopper disclosed in the following Patent Document 1 is a spring action that is necessary and sufficient for the action of fixing a sound-insulating plate inserted into a column of a support by bending a steel plate into a flat shape. Fig. 2 shows a fastener that is configured to exhibit the above.
However, this fastener is forcibly compressed and deformed into the gap between the sound insulation plate inserted in advance in the groove of the column and the groove wall of the column with a force superior to its spring action, and inserted into the groove. Since the purpose of fixing the sound insulation plate with the spring acting force released inside is achieved, it is troublesome to insert it into the gap with a strong force not defeated by the spring acting force. This is because the fixing force of the sound insulating plate depends only on the spring acting force of the fixing bracket.

  Next, the stopper for the soundproof wall disclosed in Patent Document 2 is also formed by bending the steel plate to form the main part, and from the support plate inserted into the soundproof wall stacking portion that is stacked up and down in the groove of the column. The tip of the sound insulating plate that is lowered along the inner surface is formed as a folded portion, and a moving member that moves up and down is provided at an inner portion of the folded portion. It is the structure which presses and fixes inside. However, the bolt must be operated using a tight gap space, which is inconvenient and workable.

  Further, the mounting unit for the soundproof panel disclosed in Patent Document 3 below also inserts a U-shaped member into the clearance between the soundproof wall plate and the groove wall of the column, It is recognized that the elastic deformation member inserted into the inside is operated and fixed by rotating the bolt.

The support force transmission member 1 is installed by screwing into a nut 3 prepared on the inner side of the.
The supporting force transmission member 1 is configured such that the sound insulating plate 5 is located in the groove portion 8a of the support column 8 from the position where the extended portion of the inner piece 10b forming the U-shaped portion 10 approaches the web 8c of the support column 8. The reaction force transmission portion 15 having a shape that abuts and pushes toward the opposite surface is formed.
In addition, the portion ahead of the reaction force transmitting portion 15 is inverted toward the position where the tip of the bolt 2 abuts to form an input portion 13 where the tip of the bolt 2 abuts.
The portion ahead of the input portion 13 where the tip of the bolt 2 hits is extended toward the support surface portion 12 on the way to the reaction force transmitting portion 15 by extending the inner piece 10b of the U-shaped portion 10 described above. It is characterized in that it is formed on a stretched surface portion 14 that contacts and stretches.

According to the second aspect of the present invention, in the support force transmission member 1 of the variable support force type fixing bracket according to the first aspect, the reaction force transmission portion 15 that contacts and presses against the sound insulation plate 5 is the same as that of the sound insulation plate 5. The input portion 13 that is shaped to abut against the opposite surface in a forward tilted posture and that has a shape in which the tip of the bolt 2 hits by inverting the front portion of the reaction force transmission portion 15 is a convex triangular shape toward the bolt 2. Alternatively, it is formed in a trapezoidal shape, an arc shape or a flat shape, and the protruding surface portion 14 ahead of the input portion 13 is obtained by inverting the extension portion of the inner piece 10b of the U-shaped portion 10 described above. The support surface portion 12 formed in the middle of the reaction force transmission portion 15 is configured to abut against the support surface portion 12 at an appropriate crossing angle θ and to stretch.

A washer 4 with a locking stopper provided with a locking piece 4a protruding outward in the diameter line direction of the bolt 2 at a position between
The outer side piece 10a of the U-shaped portion 10 on which the lower surface of the jaw 2 of the head 2a of the bolt 2 sits is allowed to rotate in the tightening direction of the bolt 2, but the rotation in the loosening direction is prevented from rotating. A stopper 6 for stopping the rotation of the piece 4a is provided.

The support force variable type fixing bracket according to the invention described in claim 4 includes a support force transmission member 1 formed by bending a steel plate, and the support force transmission member 1 is a flange 8b of a column 8 made of H-shaped steel or the like. And a bolt 2 for fixing the sound insulating plate 5 and a nut 3 into which the bolt 2 is screwed.
The supporting force transmission member 1 includes a U-shaped portion 10 having both the inner and outer surfaces of one flange 8b forming the groove portion 8a of the column 8 in which the sound insulating plate 5 is installed,
The bolt 2 passes through a bolt hole provided in the U-shaped portion 10 of the supporting force transmission member 1 so as to coincide with a bolt hole 8d provided in the flange 8b of the support column 8, and the U-shaped portion. Installation of the supporting force transmission member is performed by screwing into the nut 3 prepared in the inner position from the inner side piece 10b of 10,
The support force transmitting member 1 is configured such that the extension portion of the inner piece 10b forming the U-shaped portion 10 is reversed from the position approaching the web 8c of the column 8, and the sound insulating plate 5 located in the groove portion 8a. The reaction force transmission portion 15 having a shape that abuts against and pushes toward the opposite surface is formed.
Furthermore, an input portion 13 is formed at a portion ahead of the reaction force transmission portion 15 and reversed to a position and shape where the tip of the bolt 2 abuts and pressed by the tip of the bolt 2.
The part ahead of the input part 13 where the tip of the bolt 2 hits is directed toward the support surface part 12 on the way to the reaction force transmission part 15 by inverting the extension part of the inner piece 10b of the U-shaped part 10. It is characterized in that it is formed on a stretched surface portion 14 that contacts and stretches.

Since the support force variable type fixing bracket 1 (hereinafter sometimes simply referred to as the fixing bracket 1) according to the present invention has the above-described configuration, the sound insulating plate 5 is advanced into the groove portion 8a of the column 8 made of H-shaped steel or the like. Then, after shifting to one flange 8b ′ (see FIG. 5), the support force variable type fixing bracket 1 of the present invention is inserted into the gap between the sound insulating plate 5 and the front flange 8b. The U-shaped portion 10 is placed in the lateral direction (see FIGS. 4A, 4B and 5) sandwiching the inner and outer surfaces of the flange 8b, and the entire support force transmitting member 1 is pushed in the S direction and installed. At this time, since the bolt 2 has not yet been applied, it can be pushed into the gap smoothly, is convenient for installation, and the working posture is also easy. Moreover, as can be easily inferred from FIG. 5, the supporting force variable type fixing bracket 1 according to the present invention is installed in the desired number in any desired position as long as it is in the longitudinal direction of the flange 8 b of the column 8 made of H-shaped steel or the like. Convenient to use.
Next, the position of the bolt hole of the U-shaped portion 10 is matched with the bolt hole 8d (FIGS. 4A and 4B) previously provided in the flange 8b, the bolt 2 is passed in common, and the inner U-shaped in advance. Screw into the nut 3 arranged on the inner surface of the shape portion 10b.
As a result, the supporting force transmission member 1 was initially about whether or not the reaction force transmission portion 15 lightly contacts the sound insulation plate 5 as shown in FIG. 4A, but when the screwing amount of the bolt 2 is increased, The tip of the bolt 2 comes into contact with the input portion 13 of the supporting force transmission member 1 and is pushed.
When the screwing operation of the bolt 2 is further advanced, the supporting force transmission member 1 is flexibly deformed according to the amount of the bolt 2 entering, and as shown in FIG. Leads to contact. Then, as a result of the input portion 13 being pushed by the bolt 2, the distal end portion 14a of the hypotenuse portion 14 that is in a free state finally comes into contact with the support surface portion 12 (FIG. 4B), forming a tightly closed triangle. As a result, a rigid frame is formed that resists strongly.
Therefore, the reaction force transmission unit 15 receives the compressive force of the bolt 2 at the input unit 13 and receives it through the two oblique sides of the triangle, and strongly presses and fixes the sound insulating plate 5 via the reaction force transmission unit 15 (see FIG. 4B).
That is, the compression force corresponding to the screwing amount of the bolt 2 is borne by the input unit 13 and pushed, the compression force borne by the input unit 13 is transmitted to the reaction force transmission unit 15, and the sound insulating plate 5 is connected to the flange on the other side. It is firmly pressed against 8b ′ (see FIG. 5).

As described above, the sound insulating plate 5 is strongly fixed to the support column 8 by the pushing force (compression force) generated in proportion to the screwing amount of the bolt 2.
Of course, by adjusting the screwing amount to turn the bolt 2, the fixing force of the sound insulating plate 5 becomes stronger, and conversely, it can be freely returned to the original no-stress state. Therefore, various maintenance operations required for the sound insulation wall 5 after the fact can be performed very easily and efficiently.
The support force variable type fixing bracket of the present invention has a U-shaped portion 10 which sandwiches one flange 8b of the support column 8 and inserts it in the same direction as the flange 8b (lateral direction indicated by arrow S in FIG. 4A). By passing the bolt 2 through the bolt hole 8d provided in the flange 8b and screwing it into the nut 3 on the opposite side, the sound insulating plate 5 can be fixed and installed on the column 8 easily and quickly.
Of course, since the bolt 2 sews the flange 8b, an accident in which the variable supporting force fixing bracket 1 scatters never occurs.

The support force variable type fixing bracket of the present invention can start the installation work under the condition that the spring acting force of the supporting force transmitting member 1 is substantially zero, and the spring acting force increases according to the screwing amount of the bolt 2 and is arbitrarily desired. Since the fixing force of the sound insulation board 5 can be adjusted and set with the strength of the above, it is convenient and convenient.
Inevitably, on the contrary, even when the sound insulation plate 5 is removed, replaced, repaired, etc. for some reason, the bolt 2 can be rotated in the reverse direction to loosen it, so that it can work without receiving resistance caused by the spring repulsive force. is there.
Moreover, even if it is a worker's position and working posture, as can be inferred from FIG. 5, for example, it can be easily, safely and efficiently in an easy posture from the outer position of one flange 8b forming the groove 8a of the support column 8. It can be carried out. This can also be easily done by simply turning the bolt 2 to give a tightening force, or conversely releasing the tightening force.
In addition, when the bolt 2 is tightened sufficiently strongly, the detent piece 4a of the washer 4 with a locking stopper installed under the neck of the bolt head 2a is the outer piece of the U-shaped portion 10 of the supporting force transmission member 1 The stopper 6 (see FIG. 1) formed on 10a is idle in the forward rotation direction in which the bolt 2 is tightened, but when the bolt 2 is rotated in the loosening direction, the rotation stopper piece (stopper) 4a of the washer 4 is rotated. Will be stopped reliably. Therefore, inadvertent loosening of the bolt 2 is reliably prevented, and various adverse effects caused by the loosening of the bolt 2 are completely eliminated.

The extending portion of the inner piece 10b is reversed and formed on a tension surface portion 14 that abuts and projects toward the support surface portion 12 on the way to the reaction force transmission portion 15 at an appropriate crossing angle θ.

In the illustrated support force variable type fixing bracket of the present invention, a support force transmitting member 1 formed by bending a steel plate forms a main part so that FIGS. 1 and 4 can be easily understood. A bolt 2 for fixing the sound insulating plate 5 in the groove 8a by attaching the supporting force transmitting member 1 to one flange 8b of the column 8, a nut 3 (see FIG. 4A) into which the bolt 2 is screwed, and the bolt 2 The lock stopper washer 4 is used as necessary.
The supporting force transmission member 1 includes a U-shaped portion 10 that sandwiches both inner and outer surfaces of one flange 8b that forms a U-shaped groove portion 8a of a column 8 made of H-shaped steel or the like in which a sound insulating plate 5 is built.
The bolt 2 has a bolt hole provided in the U-shaped portion 10 of the supporting force transmission member 1 (not shown and reference numerals omitted) aligned with a bolt hole 8d provided in the one flange 8b of the column 8. Then, the screw shaft portion of the bolt 2 is passed through these holes in common, and is screwed and fastened to the plate-like nut 3 arranged on the inner surface side of the inner piece 10b located inside the groove of the U-shaped portion 10. The support force transmission member 1 is attached (FIG. 4A).
The nut 3 is preferably configured as a thin plate that is capable of forming the maximum thread required for fastening the bolt 2.

The supporting force transmission member 1 includes an extension portion of the inner piece 10b in the U-shaped portion 10 sandwiching both the inner and outer surfaces of the flange 8b of the support column 8 from the position approaching the web 8c of the support column 8 in the groove. A forward tilted posture that bends and reverses toward the opposite side, and is brought into contact with the opposing surface of the sound insulating plate 5 that is previously built into the U-shaped groove 8a of the column 8 and pressed against the other flange 8b '(see FIG. 5). The reaction force transmission part 15 is formed.
The portion further forward than the reaction force transmitting portion 15 is reversed to a curved shape in a position and direction in which the bolt 2 abuts against the tip of the bolt 2, and the input portion 13 with which the tip of the bolt 2 abuts is shown in FIG. 4A. , B are formed in a convex shape having a substantially triangular shape (FIGS. 4A and 4B) upward.
Further, as described above, the portion further ahead of the input portion 13 is an extended portion of the inner piece 10b of the U-shaped portion 10 sandwiching the inner and outer surfaces of the flange 8b of the support column 8 as described above. The pushing force received by the input unit 13 is reversed from the position approaching 8c and is brought into contact with the support surface part 12 formed in the middle part continuing to the reaction force transmission part 15 at an appropriate angle θ, and is thrust in a stable state. Is formed on the reaction surface transmission portion 15 on the surface portion 14.

  As described above, the basic shape of the reaction force transmitting portion 15 that contacts and pushes against the sound insulating plate 5 is a shape that contacts the opposing surface of the sound insulating plate 5 in a forward inclined posture as shown in FIG. 4A. The intent is that the reaction force transmission portion 15 that has received the pushing force of the bolt 2 contacts the sound insulating plate 5 with a wide working surface as shown in FIG. This is a configuration resulting from consideration (pressing) so that the sound insulating plate 5 is fixed as strongly and stably as possible.

As shown in FIGS. 4A and 4B, the fixing bracket according to the present invention is used by inserting one flange 8b of the support column 8 between the U-shaped portion 10 of the supporting force transmitting member 1 and fitting it. The bolt holes provided in the character-shaped portion 10 are made to coincide with the bolt holes 8d provided in the flange 8b, the bolts 2 are passed through these bolt holes in common, and further screwed into the nuts 3. The tip is caused to abut against the input portion 13 of the support force transmission member 1. Further, the bolt 2 is operated to be pushed in.
4A and 4B, the tip of the bolt 2 pushes the input portion 13 having a substantially triangular shape and compressively deforms, while the tip portion 14a of the one-side stretched surface portion 14 has both inner and outer surfaces of the flange 8b. Of the U-shaped portion 10 with the inner portion 10b sandwiched between them, the extended portion of the inner piece 10b is reversed from the position approaching the web 8c of the support column 8, and the support surface portion 12 is formed in the middle of the reaction force transmitting portion 15. It comes into contact with and is supported at an appropriate crossing angle θ. As a result, the pushing force of the bolt 2 received by the input unit 13 is effectively transmitted to the reaction force transmission unit 15 corresponding to the bottom of the triangle, and the sound insulating plate 5 pushed by the reaction force transmission unit 15 is As is apparent from FIG. 5, the flange 8 b ′ on the opposite side of the column 8 is firmly pressed and fixed.
Of course, when the bolt 2 is reversed and moved backward, the force pushing the input portion 13 of the supporting force transmission member 1 is gradually reduced and eliminated until it finally becomes zero. As a result, since the sound insulating plate 5 is in a free state in the groove portion 8a of the support column 8, replacement of the sound insulating plate 5 and other various curing and repair work can be easily and efficiently performed.

In addition, the supporting force variable type fixing bracket according to the present invention has a configuration in which the supporting force transmission member 1 is installed on the flange 8b of the column 8 using the bolt 2 and the sound insulating plate 5 is fixed as described above. As a premise, a washer 4 with a locking stopper for the bolt 2 is used.
As illustrated in FIGS. 1 to 3, a preferred embodiment of the washer 4 with a locking stopper 4 is preferably used as a pressed product such as a steel plate. The washer 4 with a locking stopper illustrated in FIG. 3 is torn the peripheral part of the hexagonal ring-shaped plate provided with the bolt hole 4c through which the bolt 2 is passed at the center part into six equal parts in the radial direction. A total of four upright pieces 4b are formed to hold the respective side surfaces of the hexagonal head 2a of the bolt 2 and realize integral rotation.
In the case of FIG. 3, of the 6 upright pieces, 2 (but not limited to 2) protruding pieces positioned in the diameter line direction do not stand up and remain in a flat shape with a diameter line. The anti-rotation pieces 4a and 4a that maintain the posture protruding in the direction are formed.
As shown in FIG. 2, the washer 4 with a locking stopper is assembled to a so-called chin lower surface of the head 2 a of the bolt 2 and used in an integral relationship with the bolt 2.

On the other hand, on the premise that the washer 4 with the locking stopper is used, the outer part piece 10a constituting the U-shaped part 10 in the supporting force transmission member 1 is rotated together with the bolt 2 as shown in FIG. The rotation stopper 4a of the washer 4 with the locking stopper 4 is allowed to rotate when the bolt 2 is rotated in the tightening direction as shown in FIG. A stopper piece 6 having a shape and structure that prevents rotation in the direction is formed in a cut-and-raised piece structure as an example in FIG.
Therefore, when the bolt 2 is rotated in the tightening direction (clockwise direction in FIG. 1), the rotation of the rotation stopper piece 4a of the washer 4 with the locking stopper is slid on the stopper piece 6 to allow the supporting force transmission member. There is no hindrance to the work of installing 1 on the flange 8b of the column 8. However, once the tightening rotation of the bolt 2 has been completed, the fact that the bolt 2 tries to rotate in the loosening direction is loosened because the edge of the anti-rotation piece 4a hits the stopper 6 and completely prevents it. Such harmful effects are prevented at all.

In addition, although the input part 13 in the said Example (FIG. 4A, B) was shown and demonstrated as a structure imitating the shape of a substantially triangular apex part, it is not this limitation.
It is essential that the input portion 13 has a configuration in which the pushing force associated with the screwing amount of the bolt 2 is efficiently reflected in the fixing action of the sound insulating plate 5 through the reaction force transmitting portion 15.
Therefore, the input unit imitating the trapezoid shown in FIG. 4C, the input unit 13 having a substantially flat shape as shown in FIG. 4D, or the input unit 13 having a nearly circular shape as shown in FIG. 4E, or illustrated in FIG. 4F The input unit 13 formed as a small protrusion as described above can be similarly implemented.

  As mentioned above, although this invention was demonstrated based on each Example, this invention is not limited to the structure of each Example mentioned above from the first. It should be noted that the scope of the present invention also includes various changes, applications, and uses of the so-called persons skilled in the art as necessary.
