Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the waste prevention plate is a large-scale one installed across the entire width of the work gondola in the left-right direction. During the construction of buildings such as high-rise condominiums, there is a risk that the waste prevention plate may break due to strong winds on high floors. Also, because it is large-scale, it is difficult for workers to handle.

[0007] Furthermore, before performing construction work such as exterior wall repair, it is necessary to install a dedicated waste prevention plate designed for each work gondola on the work gondola in advance by construction.

[0008] Therefore, an object of the present invention is to provide a scattering prevention plate for a work gondola that solves the above problems.

Means for Solving the Problems

[0009] In order to solve the above problems, the invention according to claim 1 is provided with a work gondola that can be lifted and lowered along a hoisting wire on the outer wall surface of a building to be constructed. A plate portion is provided on the horizontal frame in front of the work gondola so as to be movable in the left-right direction and swingable in the front-rear direction of the work gondola. The plate portion is rotated from a fallen posture in which it is hung down to an upright posture in a substantially horizontal state, and by moving the plate portion in the left-right direction with respect to the horizontal frame, the upright posture of the plate portion is maintained.

[0010] The invention according to claim 2 is characterized in that, in the invention according to claim 1, the upright posture of the plate portion is maintained by the shoulder portion of the plate portion coming into contact with a support column that engages with the horizontal frame of the work gondola.

[0011] The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the plate portion is detachably provided with respect to the horizontal frame of the work gondola by opening and closing a rotation ring provided on the plate portion, and the number of the plate portions can be increased or decreased according to the construction process.

[0012] The invention according to claim 4 is the invention according to claim 1 or 2, wherein a hole penetrating the front and back of the plate portion is formed in the plate portion, a covering material covering the plate portion is provided on the outer periphery of the plate portion, and the opening of the hole portion is closed with the covering material.

Effect of the Invention

[0013] According to the present invention, on the outer wall surface of the building to be constructed, a work gondola is provided so as to be movable up and down along a hoisting wire, and a plate portion movable in the left-right direction in front of the work gondola is provided so as to be swingable in the front-rear direction of the work gondola. The plate portion is rotated from the lowered lying posture to the upright posture in a substantially horizontal state, and the holding of the upright posture of the plate portion is set by the movement of the plate portion in the left-right direction in the work gondola. Therefore, compared with a structure having only a splash prevention means for a curing net, it is possible to more effectively and efficiently collect splashes such as paint.

[0014] In addition, since it can be easily assembled into an upright posture and the installation location can be appropriately relocated, it is possible to provide a splash prevention plate for a work gondola in which the plate portion can be arranged at a required position according to the construction process of the operator.

Modes for Carrying Out the Invention

[0016] The modes for carrying out the present invention will be described based on the examples shown in Figs. 1 to 6.

Examples

[0017] Figs. 1 to 6 show Example 1 of the present invention.

[0018] Fig. 1 is a perspective view showing the state in which the splash prevention plate 1 (hereinafter also referred to as the splash prevention plate) in the working gondola of Example 1 in the present invention is installed on the outer wall surface 4 of the veranda 3 in the building 2 to be constructed, and Fig. 2 is an enlarged perspective view of the working gondola 5.

[0019] As shown in Fig. 1, this splash prevention plate 1 is installed so that when performing operations such as cleaning, repairing, and painting on the outer wall surface 4 of the veranda 3 in the building 2 to be constructed with the working gondola 5, the splash prevention plate 1 receives splashes of paint and the like and dripping liquid so that they do not fall outside the working gondola 5 and below the building 2.

[0020] Hereinafter, as shown in Fig. 1, the building side is defined as the inner side A, the opposite side as the outer side B, the upper floor side of the building as the upper side C, and the lower floor side as the lower side D, and the X-X direction in Fig. 1 is the left-right direction, the Y-Y direction is the up-down direction, and the Z-Z direction is the front-back direction for explanation.

[0021] The work gondola 5 to which the anti-scattering plate 1 is attached is suspended and supported by a hoisting wire 6 hanging from a hoisting wire support 7 arranged on the rooftop of the building 2, and is provided so as to be movable up and down in the vertical direction (Y - Y direction) on the outer wall surface 4 configured in a substantially vertical shape of the building 2.

[0022] By changing the arrangement position of the hoisting wire support 7 on the rooftop in the left - right direction (X - X direction), the work gondola 5 coupled and supported by the hoisting wire 6 in a suspended state can move its suspension position in the left - right direction (X - X direction) of the outer wall surface 4.

[0023] Also, as shown in FIG. 2, on both the upper and lower stages on both side surfaces of the work gondola 5, a pair of telescopic members 8 having a telescopic function in the front - rear direction (Z - Z direction) are fixedly provided. By the tip 8a of the telescopic member 8 having a buffering function abutting against the outer wall surface 4, the collision between the main body of the work gondola 5 and the outer wall surface 4 is prevented, and the distance between the work gondola 5 and the outer wall surface 4 can be set to an arbitrary width by the telescopic function.

[0024] Note that the hoisting wire support 7 and the work gondola 5 are not limited to one, and a plurality of them can be arranged and lifted and lowered simultaneously for construction.

[0025] On the outer periphery of the work gondola 5, specifically, on the left and right surfaces in the X - X direction, the back surface of the outer side B, and the upper surface of the upper side C of the work gondola 5, a curing member 9 is installed to form a curing space 9a inside the work gondola 5, preventing the scattering of paint, cleaning liquid, etc. from the work gondola 5 to the outside of the curing space 9a during construction.

[0026] Also, as shown in FIG. 2, guide portions 10 are provided on the outer wall surface 4 on the veranda 3 side of the building 2, and a pair of the guide portions 10 are arranged at both ends of the work gondola 5 in the left - right direction.

[0027] The guide part 10 includes an upper hanging part 11 attached to the handrail part 3a of the veranda 3 on one floor (hereinafter also referred to as the upper floor) on a guide pole 10a arranged in the vertical direction of the building 2, and a lower hanging part 12 attached to the handrail part 3a of another veranda 3 (hereinafter also referred to as the lower floor) located below the one floor. A support part 13 protruding from the guide pole 10a is provided in the space below the bottom of the veranda 3 on the upper floor. The guide pole 10a is detachably attached to the veranda 3 by the upper hanging part 11 and the lower hanging part 12.

[0028] In the guide pole 10a, in the vertical direction (Y - Y direction) of the guide pole 10a, a plurality of pole through - holes 10b are opened at regular intervals on its side surface. Near the upper end of the guide pole 10a, the upper hanging part 11 is arranged, near the lower end, the lower hanging part 12 is arranged, and near the center, the support part 13 is arranged.

[0029] The upper hanging part 11 has a vertical movement part 15. The vertical movement part 15 is formed in a cylindrical shape with openings at the top and bottom. On its side surface, a plurality of vertical movement part holes 15b penetrate through the vertical movement part 15 and open at the same interval as the pole through - holes 10b.

[0030] The guide pole 10a is inserted inside the vertical movement part 15. The fixing bolt 14 is inserted through the vertical movement part hole 15b and the pole through - hole 10b and tightened with a nut (not shown). In this way, the vertical movement part 15 is fixed to the guide pole 10a. By changing the insertion position of the fixing bolt 14 in any of the plurality of provided pole through - holes 10b, the upper hanging part 11 is provided so as to be positionable in the vertical direction (Y - Y direction) of the guide pole 10a.

[0031] Also, as shown in FIG. 3, an elastic part 16 is provided on the building 2 side (inner side A) of the upper hanging part 11. The elastic part 16 is composed of a base piece 16a, an engaging piece 16b, and an elastic body 16c.

[0032] This base piece 16a is fixed to the side surface of the vertical movement part 15, and the end portion located opposite to the vertical movement part 15 bends downward and hangs inside the veranda 3.

[0033] On the base piece 16a, two elastic bodies 16c formed of metal springs are juxtaposed vertically, the elastic body 16c is interposed between the base piece 16a and the engaging piece 16b, and the base piece 16a, the elastic body 16c, and the engaging piece 16b are fixed by welding or the like.

[0034] A space E-E is formed between the engaging piece 16b and the vertical movement part 15. When the handrail part 3a is inserted into this space E-E, the engaging piece 16b moves toward the inner side A while pressing and locking the handrail part 3a of the veranda 3 toward the veranda 3 side (outer side B) and clamping the handrail part 3a.

[0035] Further, at the lower end of the engaging piece 16b, a tapered surface 16d is bent and formed so as to be separated from the handrail part 3a of the veranda 3 as it goes downward. When the handrail part 3a is inserted into the space E-E, the upper surface corner of the handrail part 3a abuts against the tapered surface 16d to guide the insertion.

[0036] Note that the lower hanging part 12 arranged near the lower end of the guide pole 10a is configured in the same manner as the upper hanging part 11, and the same reference numerals are given to the same parts and the description thereof is omitted.

[0037] Also, as shown in FIG. 2, the support part 13 is composed of a central vertical movement part 20 and a support piece 21. The central vertical movement part 20 is formed in a substantially cylindrical shape similar to the vertical movement part 15, and a holding pin 22 is installed so as to project in the axial direction through the central vertical movement part 20 while having elasticity and being biased.

[0038] Near the center of the guide pole 10a, a pin through-hole 10c opens at regular intervals in the vertical direction. The holding pin 22 is inserted through the central vertical movement part 20 into this pin through-hole 10c, whereby the support part 13 is positioned in the vertical direction (Y-Y direction) of the guide pole 10a.

[0039] Further, as shown in FIG. 3, the support piece 21 is formed on the side surface of the central vertical movement part 20 and has a predetermined length toward the building 2 side (inner side A) within the operator movement space of the veranda 3, and a latching part 21a is provided at its tip end.

[0040] A pair of these support parts 13 are arranged at both ends in the left - right direction of the work gondola 5. The other end of the curing sheet 23, one end of which is installed on the lower front surface of the work gondola 5, is hung on the latching part 21a of the support piece 21. By covering from the lower front surface of the work gondola 5 to the operator movement space of the veranda 3 with this curing sheet 23, it is possible to suppress the scattering of paint and the like below the work gondola 5 and into the veranda 3 during construction such as painting.

[0041] Further, a hooking part 25 is detachably attached to the guide pole 10a, and this hooking part 25 is connected to the winding wire 26a of the winch 26 mounted on the work gondola 5.

[0042] When the work gondola 5 performs the winding operation of the winch 26, it is biased to be pulled toward the outer wall surface 4 side (inner side A direction), and by adjusting the winding amount of the winch 26, the distance and tension between the outer wall surface 4 and the work gondola 5 can be adjusted.

[0043] Further, a scattering prevention plate 1 according to the present invention is attached to the front surface of the work gondola 5.

[0044] FIG. 4 is an enlarged perspective view of the scattering prevention plate 1. As shown in FIG. 4, the scattering prevention plate 1 is composed of a plate part 30, a locking piece 31 and a side part piece 32 located on the edge side of the plate part 30, and a rotating ring 33 for attaching to the work gondola 5, and is attached to the horizontal frame 5a of the work gondola 5.

[0045] The plate portion 30 is formed of a metal plate material having an area of about 1 m in the front-rear and left-right directions. On one side of the plate portion 30 located on the side of the work gondola 5, the locking piece 31 is formed by bending from the plate portion 30, and the locking piece 31 is formed over the entire area of the one side.

[0046] Side pieces 32 are respectively arranged at the left and right ends of the locking piece 31, and they are integrally formed so as to reinforce the shapes of the plate portion 30 and the locking piece 31 by the side pieces 32.

[0047] Also, on the side of the plate portion 30 facing the work gondola 5, a pair of rotation rings 33 are respectively provided near both ends in the left-right direction (X-X direction) of the plate portion 30.

[0048] This rotation ring 33 is a substantially circular metal fitting formed by integrally combining semi-circular members. By connecting the semi-circular members to each other with a support shaft 33a, the rotation ring 33 is provided so as to be able to open and close vertically with the support shaft 33a as the rotation axis.

[0049] Also, at the end portion 33b where the rotation ring 33 is in contact with the plate portion 30, by tightening through bolts 34 the holes (not shown) formed in this end portion 33b and the holes formed in the plate portion 30, the rotation ring 33 is fixed to the plate portion 30.

[0050] The inner diameter of this rotation ring 33 is formed wider than the width in the short direction of the locking piece 31 and the diameter of the horizontal frame 5a of the work gondola 5. The rotation ring 33 is fixed to the plate portion 30 so as to straddle the locking piece 31 from the outside, and the horizontal frame 5a of the work gondola 5 is inserted inside the rotation ring 33 for attachment.

[0051] Thereby, the splash prevention plate 1 is provided so as to be swingable in the front-rear direction (Z-Z direction) with the horizontal frame 5a as the axis and movable in the left-right direction (X-X direction) of the work gondola 5.

[0052] Note that the mounting position of the rotating ring 33 with respect to the plate portion 30 is mounted a certain amount inward from both end faces of the locking piece 31 in the left - right direction of the plate portion 30, and shoulders 31a having a width F - F are formed at both the left and right ends of the locking piece 31.

[0053] The width F - F of this shoulder 31a is ensured to be a dimension such that it is not shorter than the left - right width of the support column 5b related to the horizontal frame 5a. As shown in FIG. 5, the plate portion 30 is rotated in the front - rear direction so as to be in an upright posture, and the plate portion 30 is moved in the left - right direction with respect to the horizontal frame 5a. By bringing the shoulder 31a into contact with and locking to the side surface of the support column 5b, the downward swing of the plate portion 30 is restricted, and an upright posture in a substantially horizontal state is maintained.

[0054] At this time, as shown in FIG. 3, the tip of the plate portion 30 of the splash - proof plate 1 is located on the building 2 side (inner side A) rather than on the outer wall surface 4 of the veranda 3.

[0055] Note that since this shoulder 31a is formed at both ends of the locking piece 31, the mounting position can be changed by locking the shoulder 31a on the closer side to each support column 5b in the left - right direction of the horizontal frame 5a.

[0056] Also, as shown in FIG. 6, when the plate portion 30 is moved in the left - right direction (X - X direction) from the position where the plate portion 30 is in the upright posture to a position where the shoulder 31a of the plate portion 30 does not lock with the support column 5b, the restriction on the downward swing is released, and the plate portion 30 assumes a drooping and fallen posture and is stored under the horizontal frame 5a.

[0057] Next, a working method using the splash - proof plate 1 will be described.

[0058] First, as shown in FIG. 3, an operator boards the working gondola 5, and in the posture where the plate portion 30 of this embodiment is laid down, the working gondola 5 is moved to the outer wall surface 4 of the building 2 where the construction work is to be performed.

[0059] Next, the lower hanging portion 12 is fixed to the guide pole 10a, and the upper hanging portion 11 is not fixed but is provided so as to be movable in the vertical direction (Y - Y direction).

[0060] Next, while making the handrail portion 3a of the veranda 3 on the lower floor of the floor under construction abut against the tapered surface 16d of the lower hanging portion 12, it is positioned within the space E - E, and the handrail portion 3a is elastically locked by the elastic portion 16.

[0061] Then, the vertical movement portion 15 is slid on the guide pole 10a so that the upper hanging portion 11 is positioned near the handrail portion 3a of the veranda 3 on the upper floor. The handrail portion 3a on the upper floor is inserted into the space E - E of the upper hanging portion 11 while making it abut against the tapered surface 16d, and at that position, the vertical movement portion 15 is fixed to the guide pole 10a with the fixing bolt 14.

[0062] Next, as shown in FIG. 2, the hooking portion 25 is attached to the guide pole 10a, and by winding the winch 26, the work gondola 5 moves toward the veranda 3 side so as to be pulled toward the guide pole 10a fixed to the veranda 3.

[0063] At this time, when the telescopic member 8 attached to the work gondola 5 abuts against the outer wall surface 4, the work gondola 5 maintains the working space between the work gondola 5 and the outer wall surface 4 according to the expansion and contraction width of the telescopic member 8, and is stabilized while being biased with a certain tension against the outer wall surface 4.

[0064] After that, the holding pin 22 is pulled out to release the lock of the support portion 13, the support portion 13 is moved near the bottom of the veranda 3 within the worker movement space of the veranda 3, and the holding pin 22 is inserted through the pin through - hole 10c to hold the support portion 13.

[0065] Next, when the end of the curing sheet 23 attached to the front surface of the work gondola 5 is hung on the hooking portion 21a, the curing sheet 23 spreads from below the front surface of the work gondola 5 across the worker movement space of the veranda 3, preventing the scattering of the cleaning liquid and paint from the work gondola 5 downward and into the veranda 3.

[0066] Then, the splash prevention plate 1 of the present embodiment disposed on the outer wall surface 4 of the veranda 3 as described above is installed on the front surface of the working gondola 5.

[0067] That is, the plate portion 30 that was in the lying posture as described above is moved near the nearest support column 5b, and while the plate portion 30 is being erected forward of the working gondola 5, the shoulder portion 31a of the plate portion 30 is moved left and right on the horizontal frame 5a so as to be positioned in front of the support column 5b, and then the shoulder portion 31a is locked to the side surface of the support column 5b.

[0068] The plate portion 30 of the splash prevention plate 1 assumes a substantially horizontal standing posture toward the outer wall surface 4 side of the veranda 3, and the tip of the plate portion 30 is positioned on the building 2 side (inner side A) rather than the outer wall surface 4 of the veranda 3.

[0069] Thereby, when performing operations such as cleaning and painting on the outer wall surface 4 of the veranda 3, even if liquid drips from the outer wall surface 4 or wall fragments fall during cleaning due to deterioration of the outer wall surface 4, etc., this can be received by the plate portion 30, and splashing of paint, etc. to the outside of the working gondola 5 is prevented.

[0070] As described above, the splash prevention plate 1 of the present embodiment is installed, and the operator performs operations such as cleaning and painting on the outer wall surface 4 in the veranda 3.

[0071] Note that the position in the front - rear direction (Z - Z direction) of the splash prevention plate 1 with respect to the outer wall surface 4 of the veranda 3 can be adjusted by the expansion and contraction width of the expansion - contraction member 8, and it is also possible to bring the tip of the plate portion 30 into contact with the outer wall surface 4, dispose it directly below the construction surface, and collect the flying objects.

[0072] After the work on one floor is completed, by a procedure reverse to the above installation method, the operator releases the locking between the shoulder portion 31a of the splash prevention plate 1 and the support column 5b, makes the plate portion 30 assume a lying posture, then moves the working gondola 5 to the lower floor, and performs the same work on the next floor as described above.

[0073] With the above configuration, according to the splash prevention plate 1 of the present invention, since the plate portion 30 is provided near the construction position of the operator, compared with a means for preventing splash having only a curing net, paint and the like can be recovered more effectively and efficiently.

[0074] Also, since the holding of the standing posture of the plate portion 30 is constituted only by the movement in the left - right direction with respect to the horizontal frame 5a, the operations of installation and removal at the work site are easy and the work efficiency can be increased.

[0075] Furthermore, since it is detachably provided with respect to the horizontal frame 5a by opening and closing the rotation ring 33, without performing a dedicated design according to various working gondolas 5 and without configuring a large - scale and difficult - to - handle splash prevention device, the plate portion 30 can be installed on the working gondola 5. When the number of workers increases to a plurality or when installation over a wide range is required, etc., it is also possible to increase or decrease the plate portion 30 according to the construction process.

[0076] Also, since the splash prevention plate 1 is formed of a metal member, it has a certain weight and is difficult to break even when blown by strong wind during the construction of buildings such as high - rise condominiums. Moreover, even for a relatively heavy falling object due to its rigidity, it can be supported by the plate portion 30.

Embodiment

[0077] FIG. 7 shows Embodiment 2 of the present invention.

[0078] FIG. 7 is an enlarged perspective view of the splash prevention plate 1 in Embodiment 2 of the present invention. In the splash prevention plate 1 of this Embodiment 2, hole portions 35 penetrating through the front and back of the plate portion 30 are formed, and these hole portions 35 are formed in a plurality of divided portions with respect to the plate portion 30.

[0079] In addition, on the outer periphery of the plate portion 30, a bag-shaped covering material 36 formed of a net material, cloth, or the like is provided so as to wrap the entire plate portion 30, and the opening of the hole portion 35 is closed by the covering material 36.

[0080] According to the second embodiment, even when a hard and heavy falling object such as a fragment of a wall surface falls on the plate portion 30, the falling object collides with the hole portion 35, so that the covering material 36 serves as a buffer, and the falling object bounces from the upper surface of the plate portion 30 and does not fall outside from the splash prevention plate 1.

[0081] In addition, since the hole portions 35 are divided and opened into a plurality of pieces, they are formed in a hollowed-out state while maintaining the strength of the plate portion 30.

Embodiment

[0082] FIG. 8 shows a third embodiment of the present invention.

[0083] FIG. 8 is an enlarged perspective view of the splash prevention plate 1 in the third embodiment of the present invention. The splash prevention plate 1 in the third embodiment has a sponge-like absorber 37 having elasticity disposed on the surface of the plate portion 30.

[0084] According to the third embodiment, even when a hard and heavy falling object such as a fragment of a wall surface falls on the plate portion 30 as in the second embodiment, by colliding with the absorber 37, it is possible to prevent the falling object from bouncing from the upper surface of the plate portion 30 and falling from the splash prevention plate 1.

[0085] In addition, even if a large amount of dripping of a cleaning liquid or a paint liquid occurs during construction, the sponge-like absorber 37 can absorb a certain amount, and further, it is possible to prevent the scattering of the cleaning liquid, paint, etc. to the outside of the work gondola 5.
