Let

The method of attaching the blindfold P to a fence such as a pedestrian bridge using the conventional mounting bracket M ′ has the following problems.
(1) Since it is necessary to arrange workers on the inside and outside of the blindfold, and to perform the work by each worker, the number of workers with respect to the work volume is increased and the efficiency is poor.
(2) When working at a high place on a pedestrian bridge or a veranda, the outside worker needs a scaffold, and the outside worker handles small items such as nuts 54 and flat seats 53 or fine parts. In addition, in order to ensure the safety of passers-by, it is necessary to take measures when the small parts are dropped during the work. In addition, since the said scaffold is needed naturally also in the case of performing the attachment operation | work only of a blindfold, or its repair operation | work, work expense increases.
(3) Especially in pedestrian bridges, a spring washer or the like is used to prevent the nut from loosening over a long period of time due to the occurrence of slight vibrations in the bridge body due to the passage of pedestrians or vehicles, or due to wind pressure. However, the number of fine parts will increase.
(4) In particular, in the staircase of a pedestrian bridge, the bolt part 51a of the U-shaped bolt 51 protrudes outside in an exposed state, and there is a risk of pedestrians coming into contact with them, so that an expensive cap nut as a countermeasure. It was necessary to prevent the bolt part 51a from being exposed.

On the other hand, the structure described in Patent Document 1 is known as an installation structure for a blindfold that can be attached from the inside of the fences and has no protrusions on the outside. The mounting structure of the blindfold is a pair of connecting plates that are integrally formed with the rails inside the blindfold, or a separate rail is retrofitted to clamp the rails of the fences. Since the structure and the rail are connected by bolts and nuts, there are the following problems.
(1) Since the bolt head is completely accommodated in the rail, the rail becomes thick and the distance between the crosspiece and the blindfold is about 10 mm, and the adhesion to the crosspiece required as a blindfold is required. Disappears.
(2) The structure of the retrofitted rail not only increases the weight of the blindfold by the amount of the rail, but also requires time and labor to fix the rail, and the rail-integrated blindfold is limited to applications other than the blindfold And lack of versatility, which increases product costs.
(3) Even if the rail is firmly fixed to the crosspiece, if the structure of the rail fixed to the blind plate is not sufficient, it is dangerous because the blind plate may fall off. It is necessary to securely fix the rail to the blindfold using bolts, nuts, screws or the like.
(4) From the viewpoint of lighting and crime prevention, many blindfolds are translucent like frosted glass, and the rails are projected as shadows from the outside, which impairs the scenery or aesthetics of the fences.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

First, with reference to FIGS. 1 to 4, will be described mounting bracket M ₁ of Example 1. FIG. 1 is a perspective view of a state in which a blindfold P is attached to a fence F of a staircase portion of a pedestrian bridge. FIGS. 2A and 2B are respectively attached to an inclined portion such as a staircase portion of a pedestrian bridge. FIG. 3 is a front view showing different forming directions of a large number of bolt holes 41 in a set of two formed on the blindfold plate P, and FIG. 3 is an exploded perspective view of the mounting bracket M ₁ of the _first embodiment. (A) and (B) are cross-sectional views of a part of the mounting bracket M _{1 in} the middle of mounting the blindfold P on the fence F of the staircase portion of the footbridge and after mounting. The blindfold plate P attached to the sloped fence such as the staircase of a pedestrian bridge has a parallelogram shape, and a large number of bolt holes 41, each in a pair, are arranged at predetermined pitches in both vertical and horizontal directions. A large number of sets are formed, but as shown in FIGS. 1 and 2, a set of two bolt holes 41 formed in a blindfold P attached to a fence F of an inclined part such as a staircase part of a footbridge, As shown in FIG. 2 (a), when the line connecting the two bolt holes 41 in one set is horizontal, and as shown in FIG. 2 (b), the inclination of the blindfold P Sometimes parallel to the side. In FIG. 2, L ₁ and L ₂ are a horizontal line and a vertical line, respectively, and L ₃ indicates an inclined line inclined by an angle (θ) with respect to the horizontal line L ₁ .

The mounting bracket M _{1 of the} first embodiment is a bracket corresponding to the blindfold plate P shown in FIG. The mounting bracket M ₁ includes an outer bracket M ₁₁ disposed on the outer side of the blindfold plate P, and a partial clamp of the blindfold plate P on the vertical beam C of the fence F in cooperation with the outer bracket M ₁₁ . an inner fitting M ₁₂ disposed inside of the eyes Komoita P, consisting of an elastic seating plate K made of an elastic material such as rubber which is disposed between the vertical bars C and eye Komoita P. Outer metal M ₁₁ are those in which the pair of bolts 1 was placed the same distance and the pitch Q of a set of two bolt holes 41 formed in the eye Komoita P is fixed by welding or the like into a rectangular shape of the seat plate 2 It is. Inner fitting M ₁₂ is a cross-sectional flat co clamping plate portion 3 of the shaped arranged so as to cover the outside of the vertical bar C constituting the fence F, the opening 3a of the clamping plate 3, in the opening 3a the substantially central portion in the width direction of the substantially right angle bent portion outward, respectively, and further a double plate structure connecting plate 4 and the spring plate portion S ₁ Metropolitan of which are formed by bending approximately 180 ° on the inside. Bolt holes 4 a and S ₁ a are formed in the connecting plate portion 4 and the spring plate portion S ₁ having a double plate structure at the same pitch as the pitch Q of the pair of bolts 1 constituting the outer metal fitting M ₁₁ . The spring plate portion S ₁ of the first embodiment is integrally formed with a small angle with respect to the connecting plate portion 4 when not in use, and when the blind plate P is clamped with respect to the vertical beam C, a spring is used. The plate portion S ₁ performs a spring action by being elastically deformed toward the connecting plate portion 4. Inside fitting M _12, for example by forming with a thickness 1.2mm approximately stainless steel, to impart the spring action (elastic restoring action) on the spring plate portion S _1.

Elastic seat plate K after mounting eyes Komoita P in (during clamping), a member disposed between the connecting plate portion 4 and the eyes Komoita P of the vertical bar C and the inner fitting M _12, After mounting the blindfold P, the blindfold P avoids the direct contact with the vertical beam C and acts as a buffer, and during construction (while the blindfold P is being attached) serve to provisionally hold the outer fitting M ₁₁ against Komoita P, it causes fulfill latter function the elastic seat plate K is one of the features of the present invention. Elastic seat plate K is a substantially the same shape as the seat plate 2 and the side of the shape obtained by combining the clamping plate portion 3 of the inner fitting M ₁₂ of the outer fitting M _11, laterally to the central portion in the height direction A long hole-shaped bolt hole 6 is formed along. When inserted through the bolt 1 of the outer metal M ₁₁ into the bolt holes 6, in order to facilitate the male screw part 1a of the outer periphery of the bolt 1 is caught, the width W of the bolt holes 6 of the long hole shape, the outer fitting M ₁₁ The outer diameter (D) of the bolt 1 is determined to be smaller. It should be noted that the elastic seat plate K has the same pitch Q as the pitch Q of the two bolts 1 of the outer metal fitting M ₁₁ instead of the long hole-shaped bolt hole 6, and the outer diameter (D) of the bolt 1. It is also possible to provide two bolt holes with a small inner diameter.

Then, by using the mounting bracket M ₁ of Example 1, to attach the eye Komoita P fence F staircase portion of the pedestrian bridge, performed as follows. FIG. 5 is a partially enlarged perspective view of the state in which the outer metal fitting M ₁₁ is temporarily held on the blindfold P, and FIG. 6 shows that the blindfold P is attached to each vertical beam C of the fence F (clamped). It is a partial expansion perspective view of a state. First, as shown in FIG. 4 (A) and FIG. 5, the outer metal M ₁₁ is arranged on the outside of the two pair and a number of sets of parts of the bolt hole 41 becomes formed on the eyes Komoita P Te, and inserted two respective bolt 1 to a set of the bolt holes 41 of the eye Komoita P, the bolts 1 of the outer metal M ₁₁ projecting to the inside of the eye Komoita P, eye Komoita P It is made to pass through the bolt hole 6 of the elastic seat plate K arranged inside. Elastic seat plate K is formed of an elastic material such as rubber, moreover the width of the bolt holes 6 formed in the elastic seating plate K (W) is that smaller than the outer diameter of the bolt 1 of the outer fitting M ₁₁ (D) Since there is a dimensional relationship, by inserting the bolt 1 of the outer metal fitting M ₁₁ into the bolt hole 6 of the elastic seat plate K, the peripheral portion of the bolt hole 6 of the elastic seat plate K is elastically deformed and the width of the bolt hole 6 is increased. Is expanded. For this reason, the peripheral part of the bolt hole 6 of the elastic seat plate K bites into the male screw portion 1a on the outer periphery of the bolt 1, and the bolt 1 and the elastic seat plate K are lightly connected so as not to be separated. It becomes. As a result, the outer metal fittings M ₁₁ are respectively disposed on the outer portions of the large number of sets of bolt holes 6, each of which is a set of two blindfold plates P, and are temporarily held on the blindfold plate P.

Next, as shown in FIG. 4 (b) and 6, disposed on the outside of each longitudinal crosspieces C where a large number of outer metal M ₁₁ constitutes a fence F provisionally retained eye Komoita P, inside the fence F, by covering the outside of the vertical bar C at the clamping plate portion 3 of the inner fitting M _12, each bolt hole 4a of the connecting plate 4 and the spring plate portion S _1, to S ₁ a, eyes Komoita Each bolt 1 of the outer metal fitting M ₁₁ that is temporarily held by P and protrudes inside the blindfold P is inserted, and a nut 7 is screwed to each bolt 1. As a result, the blindfold P is drawn toward the vertical beam C of the fence F, and the blindfold P is in contact with the vertical beam C via the elastic seat plate K with respect to the vertical beam C. The portions of the two bolt holes 41 of the hidden plate P are tightened (clamped). Here, in order to fasten the blindfold plate P with respect to the vertical beam C, it is desirable to first fasten the four corners and the central portion of the blindfold plate P and then tighten the remaining portions sequentially. When tightening the nut 7 with respect to the bolt 1 of the outer metal M _11, is formed an angle with respect to the clamping plate portion 3 of the spring plate portion S ₁ of the inner fitting M ₁₂ is elastically deformed to even smaller, nut due to vibration or the like 7 is prevented from loosening. As described above, since the spring plate S ₁ is integrally formed with the inner metal fitting M ₁₂ , it is not necessary to use a separate spring washer, the number of parts of the mounting metal fitting M ₁ is reduced, and blindfolding is performed. It is possible to prevent the washer from being lost and dropped when the plate P is attached (tightened). Incidentally, FIG. 4 each spring plate portion S ₁ of the left and right (b), respectively showing a state during clamp time, and unclamped.

All of the above work can be performed by one worker inside the fence F. Even if small parts such as the nut 7 are dropped in order to work inside the fence F, Because it is inside the fence F, there is no risk of injury by hitting a pedestrian passing through the outside. Further, only the seat plate 2 of the outer metal fitting M ₁₁ having a flat plate shape is exposed outside the blindfold plate P, and the eye plate 51 is similar to the U-shaped bolt 51 of the conventional mounting metal fitting M ′. Since there are no protrusions protruding outside the cover plate P, there is no risk that the pedestrian will be caught by the protrusions and injured. Furthermore, unlike the mounting structure of Patent Document 1, the blindfold P is a vertical beam C that is a structure constituting the fence F, although all the mounting work of the blindfold P is performed inside the fence F. In contrast, the elastic seat plate K is disposed so as to be separated from the vertical rail C by the thickness of the elastic seat plate K. In addition, in FIG. 1, 21 and 22 show the support | pillar and handrail of the iron fence F, respectively.

In addition, when a set of two bolt holes 6 formed in the blindfold plate P is formed along the direction of the inclined line L ₃ , a mounting bracket M ₂ as shown in FIG. 7 is used. The Outer metal M ₁₁ and the elastic seating plate K constituting the mounting bracket M _2, the although mounting bracket is identical to that of M _1, is different only the inner fitting M ₁₂ '. That is, the upper and lower end edges of the connecting plate portion 4 ′ and the spring plate portion S ₁ ′ of the inner metal fitting M ₁₂ ′ and the portion facing the opening 3a ′ of the clamp portion 3 ′ are parallel to the inclined line L _3. It is that it is formed to be different from the inner fitting M _12. Incidentally, the outer fitting M ₁₁ and the elastic seating plate K may be arranged to be inclined by an angle (theta).

In addition, the blindfolds used for the landings of the pedestrian bridge and the fence at the crossing of the road are rectangular, unlike those used for the staircases. Is formed. Even at the landings of pedestrian bridges and road crossings, it is possible to tighten the blindfold plate (clamping work) inside the fence, but the advantage to be noted is that the blindfold plate P is tightened inside the fence. Since this can be done, a scaffold that was indispensable in the conventional mounting bracket M ′ is not necessary. Further, if the pitch Q of the two bolts 1 of the outer fitting M ₁₁ of each of the fittings M ₁ and M ₂ is the same as the pitch Q of the bolt part 51a of the U-shaped bolt 51 of the conventional fitting M ′, When the cover plate P is repaired, the mounting brackets M ₁ and M _{2 according} to the present invention can be used instead of the conventional mounting bracket M ′.
