Description

  The present invention relates to a mounting device for a soundproof panel that is attached to the outer periphery of a temporary scaffolding at a construction site and suppresses leakage of construction noise to the outside, and in particular, the present invention relates to a soundproofing panel for a frame scaffold with a wedge-tightening type. The present invention relates to a mounting device for a soundproof panel for a scaffold that can be attached to the outer periphery of the scaffold.

  FIG. 10 shows a state in which the soundproof panel 1 for the frame scaffold is attached to the outer periphery of the frame scaffold assembled by the gate-shaped building frame F by the curing clamp K, and FIG. 12 shows the soundproof panel 1 for the frame scaffold and the curing. A clamp K is shown. In the frame scaffold shown here, the height of the building frame F (the length of the pedestal f) is 1700 mm, and the insertion portion of the connecting pin P between the pedestals f and f of the building frames F and F to be added is 25 mm. ing. As shown in FIG. 12 (a), the frame scaffold soundproof panel 1 has peripheral frames 1b, 1b, 1c, 1c projecting inward from the peripheral edge of the panel body 1a, and upper and lower edge frames of the peripheral frame. 1b is provided with through holes 2 for pin insertion at both ends, and the soundproof panel 1 has a height of 862mm and a width of 1819mm. Therefore, the soundproof panel 1 is stacked in two upper and lower stages. It can handle one frame F of the scaffold.

  Further, as shown in FIGS. 12B and 12C, the curing clamp K includes a pipe clamp 31 having a known structure including a base member 28, a pressing member 29, and a tightening bolt nut 30, and the clamp 31. A pair of L-shaped mounting pins 32, 32 fixed to the base member 28, and each L-shaped mounting pin 32 is formed in an L shape by a horizontal portion 32a and a vertical portion 32b, and is horizontal. The base end portion of the portion 32 a is provided so as to project at a right angle with respect to the lower surface of the base portion of the base member 28. The reason why there are two L-shaped mounting pins 32 is that they are inserted through the adjacent through holes 2 and 2 of the two left and right soundproof panels 1 and 1 adjacent in the horizontal direction, as shown in FIG. is there.

  In attaching the soundproof panel 1 to the outer periphery of the frame scaffold, first, as shown in FIG. 12, the pipe clamp 31 of the curing clamp K is held and fixed to the lower end of the outer leg column f of the lowermost building frame F. Then, the vertical portion 32b of the L-shaped mounting pin 32 is inserted through the through hole 2 of the lower edge frame 1b of the soundproof panel 1 from below to above. In this case, since the curing clamp K has a pair of L-shaped mounting pins 32, 32, the vertical portions 32b, 32b of the mounting pins 32, 32 are adjacent to each other in the horizontal direction as shown in FIG. The left and right soundproof panels 1 and 1 are inserted through the adjacent through holes 2 and 2.

  Next, the vertical clamp 32b of the L-shaped mounting pin 32 is secured to the first-stage soundproofing by holding and fixing the pipe clamp 31 of the curing clamp K to the vertical middle part of the outer pedestal f of the same bottom-stage building frame F. Inserting the through hole 2 of the upper edge frame 1b of the panel 1 and the through hole 2 of the lower edge frame 1b of the second-stage sound insulation panel overlaid on the first-stage sound insulation panel 1 upward from below. Similarly, at this time, the vertical portions 32b and 32b of both the mounting pins 32 and 32 are inserted into the adjacent through holes 2 and 2 of the two soundproof panels 1 and 1 adjacent to the left and right. In this way, the first-stage soundproof panel 1 is held. Subsequently, the pipe clamp 31 of the curing clamp K is gripped and fixed to the upper end portion of the outer pedestal f of the lowermost building frame F, and the through hole 2 of the upper edge frame 1b of the second-stage soundproof panel and the third-stage The second-stage soundproofing panel 1 is held by being inserted into the through-hole 2 of the lower edge frame 1b of the soundproofing panel upward from below. In this way, with the two first-stage and second-stage soundproof panels 1 and 1 attached, the upper end position of the second-stage soundproof panel 1 is substantially the same as the upper end position of the pedestal f of the same bottom-stage building frame F. At the same position.

  Thereafter, in the manner as described above, the pipe clamp 31 of the curing clamp K is fixed to the lower end portion, the intermediate portion, and the upper end portion of the pedestal f in the next-stage side building frame F, respectively, and in the next-stage building frame F By fixing the pipe clamp 31 of the curing clamp K to the lower end portion, middle portion, and upper end portion of the pedestal f, the third-stage sound insulation panel 1, the fourth-stage sound insulation panel 1, the fifth-stage sound insulation panel 1,・ ・ Can be attached sequentially.

  When the soundproof panel 1 for a frame scaffold is attached to the outer periphery of the frame scaffold as described above, a soundproof panel having a height that can correspond to the height of the building frame F is used. 31 is the presence of any obstruction (such as the protruding portion of the lock pin of the connecting pin P) on the pedestal f where the lower end position, the middle position and the upper end position of the pedestal f of the building frame F are present. It can always be held and fixed at a position where it is not.

  However, when the soundproof panel 1 for the frame scaffold is to be attached to the outer periphery of the wedge-tightening type scaffold using the curing clamp as described above, the scaffolding column of the wedge-tightening type scaffold is particularly fixed at regular intervals. Since the unit length of the scaffolding strut and the height dimension of the framed scaffolding soundproofing panel 1 do not correspond with the flanges or pockets attached, if you try to stack the soundproofing panels 1 sequentially from the bottom, The pipe clamp mounting position of the curing clamp K on the support may overlap with an obstacle such as a flange, a pocket, or a wedge tightening portion, so that the curing clamp cannot be used and the soundproof panel cannot be mounted. A state in which the curing clamp cannot be used will be described below with reference to FIG.

  FIG. 11 shows a case where the soundproof panel 1 for the frame scaffolding is to be attached to the outer periphery of the wedge-tightening type scaffold by the curing clamp K. The scaffolding column 3 of the frame scaffold shown in FIG. Is 1800 mm, and a plurality of flanges 4 with wedge holes are protruded at regular intervals, and are connected by connecting pins 5. The height of the supporting pillar 3 used in the lowermost stage is 900 mm which is a half size. Further, the inner scaffolding pillar 3 and the outer scaffolding pillar 3 are connected by a cloth material (lateral stay) 6. The soundproof panel 1 to be attached to the outer periphery of the wedge-tightening type scaffold is the above-mentioned soundproof panel for frame scaffold shown in FIG. 12 (a), and has a height of 862 mm and a width of 1819 mm.

  In order to attach the frame scaffolding soundproof panel 1 to the outer periphery of the wedge-tightening type scaffolding with the curing clamp K, first, the pipe clamp 31 of the curing clamp K is fixed to the lower end portion of the outermost scaffolding support 3 at the lowermost stage. Then, the vertical portion 32b of the L-shaped mounting pin 32 is inserted into the through-hole 2 on the lower edge frame 1b side of the first-stage soundproof panel 1, and then the pipe clamp 31 of the curing clamp K is attached to the upper end portion of the scaffolding column 3. When trying to fix, the lock pin 5a of the connecting pin 5 that connects the lower end of the next-stage scaffolding column 3 protrudes as shown in the enlarged view on the lower right side of FIG. Therefore, the vertical portion 32b of the L-shaped mounting pin 32 is connected to the through-hole 2 (see FIG. 12A) of the upper edge frame 1b of the first-stage sound insulation panel 1 and the second-stage sound insulation panel 1. Through hole 2 in lower edge frame 1b ((a) in FIG. 12) See)).

  Further, the lock pin 5a does not protrude from the upper end portion of the outermost scaffolding support 3 at the lowermost stage, so that the pipe clamp 31 can be fixed, and the through hole 2 of the upper edge frame 1b of the first-stage sound insulation panel 1 and the second-stage sound insulation. Even if it can be inserted into the through-hole 2 of the lower edge frame 1b of the panel 1, when trying to fix the pipe clamp 31 of the curing clamp K to the upper end of the next stage (second stage) scaffolding column 3, there is As shown in the enlarged view on the upper right side of FIG. 11, since the flange 4 is located and there is a wedge tightening connecting portion for connecting one end portion of the cloth material 6 to the flange 4, the curing clamp K cannot be attached. The soundproof panel 1 for a scaffold cannot be installed.

  If the soundproof panel for the frame scaffolding cannot be installed on the wedge-clamping scaffolding as described above, a soundproofing panel dedicated to the wedge-clamping scaffolding having a height dimension that can correspond to the length of the scaffolding column for the wedge-clamping scaffolding is prepared. It is necessary to do so, but this will cause the equipment cost to rise. In view of such circumstances, the present invention enables the installation of existing sound insulation panels for frame scaffolds, which are frequently used at present, to the wedge-tightening type scaffolds.

  The effect of the invention by the above-described solution means will be described with reference numerals in the embodiments described later. The soundproof panel mounting device A for a scaffold according to the first aspect of the present invention is vertically arranged on the side of the scaffolding column 3. The mounting arm 17 arranged to extend, the pipe clamp 11 projecting at a required position on one side of the mounting arm 17, and the horizontal portion 13a and the vertical portion 13b are formed in an L shape, and the horizontal portion 13a side is formed. The L-shaped mounting pin 13 is fixed to the pipe clamp 11 at a position away from the pipe clamp 11 on the other side of the mounting arm 17, and the vertical portion 13 b of the L-shaped mounting pin 13 is connected to the soundproof panel 1.

Further, since the mounting device A according to the present invention is composed of one unit having a simple structure, the manufacturing cost is low, and the handling and workability are improved.

In the soundproof panel mounting device A for a scaffold according to the present invention, the L-shaped mounting pin 13 of the mounting arm 17 is provided at one position away from the pipe clamp 11 fixed to the scaffolding column 3 upward or downward. However, in the case of one place, a long mounting arm 17 is required upward or downward substantially equivalent to a range in which the pipe clamp 11 cannot be attached due to an obstacle on the scaffolding column 3. In this case, if the distance between the fixing portion of the mounting arm 17 (the position of the pipe clamp 11) and the position of the L-shaped mounting pin 13 to which a horizontal force is applied is long, the L-shaped mounting pin 13 is horizontally moved by the horizontal force. The attachment arm 17 is easily bent when pulled. Therefore, in the present invention, the L-shaped mounting pin 13, to provide the upper and lower end portions side two places of attachment arms 17 apart to pipe clamp 11 both above and below the other side of the mounting arm 17 As can be seen by referring to the embodiment shown in FIG. 6 (a), the pipe clamp non-mountable range H where the pipe clamp 11 cannot be mounted is covered about half from above and about half from below. Therefore, the distance from the fixed portion to the L-shaped mounting pin 13 provided on the mounting arm 17 can be minimized, thereby maintaining the strength.

As described in claim 2 , the L-shaped mounting pin 13 on the upper end side fixed to the other side of the mounting arm 17 projects the vertical portion 13b upward, and the L-shaped mounting on the lower end side. When the pin 13 has the vertical portion 13b protruding downward, it can be used by turning it upside down according to the mounting position of the pipe clamp 11 on the scaffolding column 3. Thereby, the installation range of the pipe clamp 11 can be expanded.

As described in claim 3 , the arm main body 17a of the mounting arm 17 is formed in a groove shape, and the flange 4 or the pocket 24 of the scaffolding column 3 is formed in the groove shape, so that the pipe clamp 11 The pipe clamp 11 is mounted on the scaffolding column 3 by forming it in a shape avoiding it so as not to interfere with the flange 4 or the pocket 24 of the scaffolding column 3 while being fixed to the scaffolding column 3. The possible range can be expanded.

The soundproof panel mounting device B for a scaffold according to a fourth aspect of the present invention is latched to the panel mounting single pipe 8 arranged along the scaffolding column 3 of the wedge-tightening type scaffolding and the flange 4 of the scaffolding column 3. A single-tube fixing bracket 12 formed by fixing a U-shaped fitting 10 fixed by a wedge 9 to a pipe clamp 11 and a horizontal portion 13a side of an L-shaped mounting pin 13 are fixed to the pipe clamp 11. It is composed of a panel-mounting clamp 14, and the pipe clamp 11 of the single-tube fixing bracket 12 and the pipe clamp 11 of the panel-mounting clamp 14 are made independent of each other on a single tube 8 spaced apart from the scaffolding column 3 by a certain distance. Therefore, the single tube fixing bracket 12 may be fixed to the scaffolding column 3 at a position avoiding obstacles such as the flange 4 on the scaffolding column 3 side, and the panel mounting clamp 14 may be , Scaffolding support Since the 3 side of the obstacle can be secured to the scaffold post 3 Regardless, I'm using these brackets 12 and the clamp 14, the framework scaffolding for soundproofing panel 1 can be attached accurately to the wedge clamping scaffold The

  Further, in this soundproof panel mounting device B, the single tube fixing bracket 8 is fixed to the scaffolding column 3 by the single tube fixing bracket 12, and the single tube fixing bracket 12 is connected to the flange 4 of the scaffold column 3 or A U-shaped fitting 10 that is hooked in the pocket 24 and fixed by the wedge 9 is fixed to the pipe clamp 11, and once the U-shaped fitting 10 is fixed to the flange 4 or the pocket 24 by the wedge 9, Since it does not cause rotation with respect to the scaffolding column 3 and can be securely fixed, positioning of the panel mounting single pipe 8 with respect to the scaffolding column 3 is facilitated, and therefore, the mounting operation of the soundproof panel 1 is facilitated.

  A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a soundproof panel mounting device for a scaffold according to the present invention for mounting a soundproof panel for a frame scaffold to a wedge-tightened type scaffold. 1 (a) and 1 (b) show the state of use of the soundproof panel mounting device A, FIG. 2 (a) is a front view of the soundproof panel mounting device A, and (b) is a plan view. FIG. 2C is a plan view showing a state in which the pair of L-shaped mounting pins 13 are passed through the adjacent through holes 2 of the two left and right soundproof panels 1 and 1. As shown in FIG. 1, the soundproof panel mounting device A includes a mounting arm 17 disposed so as to extend in the vertical direction on the side of the scaffolding column 3, and a central position in the vertical direction on one side of the mounting arm 17. The projecting pipe clamp 11 is formed in an L shape by the horizontal portion 13a and the vertical portion 13b, and the horizontal portion 13a side is fixed to the upper and lower ends of the mounting arm 17 at the other side of the mounting arm 17. It is constituted by a pair of upper and lower L-shaped mounting pins 13 and 13.

  The wedge-tightening type scaffold has the structure shown in FIG. 11, and the structure of the soundproof panel 1 is shown in FIG. 12 (a). Therefore, the reference numerals of the constituent members are used as they are, and the description thereof is omitted. The pipe clamp 11 has the same structure as the pipe clamp 31 of the curing clamp K shown in FIGS. 12B and 12C, and includes a base member 11a, a holding member 11b, and a tightening bolt nut 11c. Become.

As can be seen from FIGS. 2A to 2C, the mounting arm 17 is attached to the groove-shaped arm main body 17a and the corner portions of the upper and lower end surfaces of the groove-shaped arm main body 17a in an oblique manner. The pipe clamp 11 is formed by fitting an attachment member 18 fixedly projecting on the base member 11a into the groove portion at the center in the longitudinal direction of the U-shaped arm body 17a. By welding, it is fixedly mounted so as to protrude from the central part in the vertical direction of one side of the mounting arm 17. The mounting arm 17 is formed by using the groove-shaped arm main body 17a in this way because the mounting arm 17 is mounted on the scaffolding column 3 with the pipe clamp 11 fixed to the scaffolding column 3 on the flange 4 (or pocket). This is for avoiding the flange 4 (or pocket) so as not to interfere with the flange 4 (or pocket) even when the position is reached (see (c) of FIG. 2 ). By making the mounting arm 17 in such a shape, the range in which the pipe clamp 11 can be mounted on the scaffolding column 3 can be expanded.

  When attaching the soundproof panel 1 for a framed scaffold using the scaffold soundproof panel mounting apparatus A having the above-described configuration, as shown in FIG. 1 (a), the lower soundproof panel 1 and the upper soundproof panel 1 If the pipe clamp 11 is fixed at the position shown in FIG. 6A of the scaffolding column 3 when the joint G is at the level position of the connecting pin 5 of the scaffolding column 3, the L-shaped mounting The pin 13 cannot be inserted into the through holes 2 and 2 in the joint G between the upper and lower panels 1 and 1, and the lock pin 5b protrudes even if the pipe clamp 11 is slid upward slightly. The pressing member 11b of the clamp 11 is caught on the lock pin 5b and cannot be slid. In this case, as shown in FIG. 2 (c), the mounting arm 17 has the arm main body 17a made of a groove-shaped material as described above. The groove-shaped arm main body 17a and the reinforcing member 17b are also in a state where they can receive the peak portion 4b of the flange 4 and are not interfered with the flange 4.

  If the pipe clamp 11 is fixed to the scaffolding column 3 at the position shown in FIG. 1 (a) as described above, it cannot be inserted into the through holes 2 and 2 in the joint G of the upper and lower panels 1 and 1. Therefore, as shown in FIG. 1 (b), the pipe clamp 11 is removed, and the mounting device A is lifted from the position of FIG. 1 (a) to the upper half of FIG. 1 (b) as shown by a solid line. If the pipe clamp 11 is fixed to the scaffolding column 3 above the lock pin 5a of the connecting pin 5, the L-shaped mounting pin 13 at the lower end of the mounting arm 17 is connected to the joint between the upper and lower panels 1, 1. It is possible to insert the through holes 2 and 2 accurately at G. Alternatively, as shown by the phantom line in the lower half of FIG. 1 (b), the pipe clamp 11 is fixed to the scaffolding column 3 at a position where the attachment device A is pulled up slightly from the position of FIG. 1 (a). For example, the L-shaped mounting pin 13 at the upper end of the mounting arm 17 can be accurately inserted into the through holes 2 and 2 at the joint G between the upper and lower panels 1 and 1. In the latter case, that is, in the attachment state shown in the lower half of FIG. 1 (b), the end 5b of the lock pin 5a protrudes at the attachment position of the pipe clamp 11 holding the scaffolding column 3 (FIG. 1). However, since the inner surface of the holding member 11b of the pipe clamp 11 is formed in a concave shape, the protruding end portion 5b is received by the concave portion.

  The soundproof panel mounting device A for a scaffold shown here includes a mounting arm 17, a pipe clamp 11 projecting at the center in the vertical direction on one side of the mounting arm 17, and a mounting arm on the other side of the mounting arm 17. 17 is composed of two upper and lower L-shaped mounting pins 13 and 13 fixed to the upper and lower end portions, and the L-shaped mounting pin 13 used for mounting the soundproof panel 1 is one of the upper and lower two. Any one of the other mounting pins 13 is only housed in the soundproof panel 1. In the sound insulation panel mounting device A indicated by a solid line in the upper half of FIG. 1 (b), the lower L-shaped mounting pin 13 is used for mounting the soundproof panel 1, and the upper L-shaped mounting pin 13 is In the sound insulation panel mounting device A, which is housed in the sound insulation panel 1 and indicated by a virtual line in the lower half of FIG. 1B, the L-shaped mounting pin 13 on the upper side is used for mounting the sound insulation panel 1. The lower side L-shaped mounting pin 13 is only housed in the soundproof panel 1.

  The soundproof panel mounting device A according to the present invention projects the pipe clamp 11 on one side of the mounting arm 17 at a required position, and at the other side of the mounting arm 17 away from the pipe clamp 11 upward or downward. What is necessary is just the structure to which the L-shaped attachment pin 13 was fixed. That is, one L-shaped attachment pin 13 may be provided at a position away from the pipe clamp 11 upward or downward. Therefore, according to the soundproof panel mounting device A according to the present invention, the pipe clamp 11 is located at a position where the vertical portion 13b of the L-shaped mounting pin 13 can be inserted into the through hole 2 of the soundproof panel 1 and the soundproof panel 1 can be held. Can be attached to the wedge-tightening type scaffolding by holding and fixing to the scaffolding column 3 at a position where the obstacle can be avoided on the scaffolding column 3. In addition, the attachment device A according to the present invention comprises a single unit having a simple structure in which the pipe clamp 11 and the L-shaped attachment pin 13 are integrally attached to the attachment arm 17. Good handling and workability.

  Moreover, in the soundproof panel mounting device A for a scaffold according to the present invention, the L-shaped mounting pin 13 of the mounting arm 17 is located at one position away from the pipe clamp 11 fixed to the scaffolding column 3 upward or downward. However, when it is provided at one location, the upper or lower side is approximately the same as the range in which the pipe clamp 11 cannot be attached by an obstacle (flange, pocket, wedge tightening portion, etc.) on the scaffolding column 3. A long mounting arm 17 is required. In this case, when the distance between the fixing portion of the mounting arm 17 (the position of the pipe clamp 11) and the position of the L-shaped mounting pin 13 to which a horizontal force is applied becomes long, the L-shaped mounting pin 13 is horizontally moved by the horizontal force. When pulled, the mounting arm 17 is easily bent. Therefore, as in each embodiment shown in FIGS. 1 to 6, the upper and lower ends of the mounting arm 17, where the L-shaped mounting pin 13 is separated from the pipe clamp 11 both vertically at the other side of the mounting arm 17. As shown in FIG. 6A, which will be described later, the pipe clamp non-mountable range H in which the pipe clamp 11 cannot be mounted is about half from above and about from below. You can divide and cover as if you cover half. Therefore, the distance from the fixed portion to the L-shaped mounting pin 13 provided on the mounting arm 17 can be minimized, thereby maintaining the strength.

  3 to 5 show various embodiments of the soundproof panel mounting device A for scaffolds. The soundproof panel mounting device A in FIG. 3 projects a pipe clamp 11 at the center in the vertical direction on one side. An embodiment in which L-shaped mounting pins 13 protrude from the upper and lower ends of the other side of the mounting arm 17 is shown, and the vertical portion 13b of the upper L-shaped mounting pin 13 protrudes upward. On the other hand, the L-shaped mounting pin 13 on the lower side has a vertical portion 13b protruding downward.
