Description

The present invention relates to a roof frame for protecting an external framework scaffold fixed around the outside of a building, and a rain protection device for an external framework scaffold using the roof frame for protecting the external framework scaffold.

External framework scaffolding is required for repair work on the exterior walls of buildings. The external framework scaffolding is made up of the minimum necessary components such as steel pipe supports, horizontal beams, brackets for connecting and fixing the inner and outer supports, handrails to prevent falls, and treadles so that they can be easily assembled and dismantled on site. The support column protrudes above the bracket and is open at the top. Such external framework scaffolding is intended for fair weather use. When it rains or snows, rainwater hits the exterior walls, reducing the quality of the construction surface and making the treads wet, making work dangerous. In this way, if the work period includes a rainy or snowy day, the work must be stopped during that period, resulting in a delay in the delivery date from the original schedule, and in addition, when starting the repair work on the exterior wall of the building, the work must be stopped during that period. Accommodation costs for the extra days required for the accommodations secured for those involved in the work must be paid, resulting in a large economic loss. Therefore, devices have been devised that allow exterior wall repair work to be performed even in rainy weather in the same way as in sunny weather.

A single tube with a plate provided at the upper end is fixed to the top of the support of the external framework scaffold so that the plate is located above the top of the support, and single tubes for hoisting are arranged vertically alternately between adjacent plates, The rectangular rain protection sheet has a blind hole for inserting a single tube at a position parallel to the inner and outer edges of the inner and outer edges, and extends the outer part of the blind hole for inserting a single tube on the rear edge side from the top of the rear column. The hanging protruding part is placed on the exterior side, and the inner end with a single pipe inserted into the inner end blind hole for single pipe insertion is placed on the roof of the building, and the rear end edge side blind hole for single pipe insertion is provided in the plate. A winding single pipe is installed to cover the inner support from the roof and extend the rainproof sheet to the outside of the outer support, so that rainwater that falls between the plate and the inner support is transported to the roof of the building and distributed outside the plate. For exterior wall finishing work, the rainwater that falls on the roof falls into the walkway on the opposite side of the building, and when it is not needed, a winding device is used to wrap the rainproof sheet around a single winding pipe and hold it on the plate surface. A rain protection device has been proposed (for example, see Patent Document 1). In the construction rain protection device for exterior wall finishing disclosed in Patent Document 1, firstly, a single pipe is attached to the middle part of the rain protection sheet in the inside and outside direction, and this single pipe is hung on the upper end of the inner support on the side of the building. Since the rainproof sheet is spread from the outer support to the inner support and across the rooftop, the portion of the rainproof sheet that is spread between the inner and outer support becomes depressed due to the weight of the rainwater, reducing the amount of water sent to the rooftop. This could lead to a situation where the single pipe gets caught on the building side at the upper end of the inner support and falls onto the scaffolding. Second, if a wet sheet is attached to the plate with a heavily wrapped rainproof sheet, the weight that will be applied to the outer support will increase, causing the weight to become unbalanced with the inner support and causing the scaffold to tilt outward. There was a problem that this could lead to unstable situations.
A cover frame consisting of the outer end of the main pipe tilted upward toward the building and a plurality of connecting pipes vertically installed midway along the length of the main pipe is fixedly attached to the supports of the external framework scaffolding, and adjacent cover structures are A roof for external framework scaffolding has been proposed in which braces and horizontal members are installed between the frames, and a curing sheet is attached to the covering frame using ropes, allowing rain on the curing sheet to fall to the walkway on the opposite side of the building. (For example, see Patent Document 2). In the device disclosed in Patent Document 2, the main pipe is tilted upward toward the building, so rainwater falls into the passageway on the opposite side of the building and the falling sound becomes a noise. Furthermore, the passageway is flooded with water, and it is necessary to use a curing sheet. Since the roof is formed by tying it to the covering frame with ropes, there is a problem in that it takes time to assemble and dismantle.
A reinforcing core for preventing wrinkles is sewn into the rectangular sheet at a position close to the building side and at both ends, and at the side, there is an overlapping connection part between adjacent sheets through joining members such as buttons and buttonholes. A curing sheet was devised in which connecting members made of strings, etc. were provided at regular intervals on the side of the sheet and inside the reinforcing core, and a sheet lifting member was installed on the side of the sheet. A metal round bar with an inner end sewn with anti-wrinkle reinforcing core, a string passed through the button hole and tied to the roof structure, and attached to the outer end along the length. By hanging a sheet winding roll consisting of a sheet winding roll and moving an endless sheet winding rope suspended around the sheet winding roll, the wound sheet is stored on the outside of the scaffold (for example, Patent Document (See 3). The sheet disclosed in Patent Document 3 has a round bar made of a metal pipe or the like on the outer edge of the sheet, so when it is rolled up, a load is applied to the outside of the scaffold and there is a risk that the scaffold will tilt outward. However, since the sheet is wound from the building side to the outside of the scaffolding, when removing a wet and heavy sheet, move the endless sheet winding rope provided on each individual sheet to remove the corresponding sheet. It is necessary to wind each sheet onto a winding roll for each sheet rolled out on the roof structure, which requires time and effort to open the upper part of the scaffolding, and also causes the center of gravity of the scaffold to be unbalanced. Because of the roof structure's sloping shape, there was a problem in that rainwater would fall on the opposite side of the building from the walkway, and the sound of this falling would create noise and cause a nuisance to the neighborhood.
A telescopic pipe that extends toward the building is installed at the inner end of the main pipe that is tilted upward toward the building, and a column frame is connected to the outer end of the main pipe at a midway point in the length direction, and a lower frame is connected between the column frames. The column frames were each connected to the supports of the external framework scaffolding, reinforcing steel pipes were installed between the ends of the extensible pipes, and the inner edge of the curing sheet with the rooting steel pipe was placed on the roof of the building. A roof frame for curing external framework scaffolding has been proposed in which reinforcing steel pipes, main pipes, and the outside of the scaffold are extended from the roof of the building and attached to the frame using clips, with the outer edge of the sheet hanging outside the scaffold (for example, , see Patent Document 4). With the method disclosed in Patent Document 4, there is a risk that the center of gravity of the scaffold will be on the building side, causing the scaffold to tilt toward the building, and when storing the sheet, the sheet may fall to the back side after removing the rooting steel pipe. This poses a problem in that it takes time and effort to attach the seat for next use.
Posts of different lengths and short lengths to be attached to the pillars of the external framework scaffolding are vertically installed on the beam material, the beam material is tilted downward toward the building side, and drainage holes are opened on the building side of the sheet spread on the top surface of the beam material, and the drainage holes and It has been proposed to provide a communicating drain pipe below the sheet, to send rainwater from the sheet to the building side, and to drain water from a drainage hole to the roof of the building via the drain pipe (for example, Patent Document 5 reference). In the invention disclosed in Patent Document 5, since both ends of the sheet are engaged with hooks provided on the upper surface of the beam to spread the sheet, the sheet cannot be spread unless the grip is released from above the beam. There was a problem in that it was not possible to remove the beam from the beam material, and assembly and disassembly work was time-consuming.
The methods disclosed in Patent Documents 1 to 5 above open and close sheets in and out of the scaffold, and holding a rain-wet sheet on one side of the scaffold disrupts the balance of the center of gravity of the scaffold. The wet sheets were heavy and made cleaning up difficult.
In addition, it has been proposed to open eyelets on both the left and right ends of a rainproof sheet installed on a wall, pass endless ropes through the eyelets alternately, and move the endless ropes to raise and lower the sheet. (For example, see Patent Document 6). If it is assumed that the sheet disclosed in Patent Document 6 is spread by placing a rope in the length direction on the roof part of an external framework scaffold, the sheet cannot be spread between the scaffold and the building, so the outer wall gets wet. Furthermore, there are problems in that the ropes hang down on both edges of the scaffolding and become a nuisance.

The inner main pipe and the outer main pipe are inclined at the same slope so as to be inclined upward toward the outer end .
The invention according to claim 2 is a rain protection device for external framework scaffolding using a roof frame for curing external framework scaffolding, which comprises the roof frame for curing according to claim 1, an inner curing sheet, and an outer curing roof frame. It consists of a sheet, an inner rope, an outer rope, a connecting member made of a string , and a ring, the inner connecting pipe is connected to the inner support of the external framework scaffold, and the outer connecting pipe is connected to the outer support of the external framework scaffold. On the roof frame for curing that is connected and assembled on the upper end of the external framework scaffold, the inner rope and the outer rope are stretched in a parallel position between the opposing longitudinal bars of the external framework scaffold, and the inner rope and the outer rope are stretched in a parallel position. The outer curing sheet and the inner curing sheet are spread out with an overlapping part, and the inner curing sheet is non-water permeable and extends along the inner and outer edges of a rectangular sheet that is long in the width direction. Connecting member mounting holes are provided at predetermined intervals, and the outer curing sheet is non-water permeable and has a rectangular sheet that is long in the width direction. Attachment holes are provided, and on the inside of the bottom surface of the seat, mounting pieces with ring attachment holes are arranged in rows at predetermined intervals in the width direction and spaced apart in the inner and outer directions, and rings can be attached to the ring attachment holes.

By connecting and assembling the main pipes of the inner roof frame and outer roof frame, one roof frame for protection is formed. Therefore, when dismantling the structure, the connecting parts of the main pipes must be removed and removed from the building side (hereinafter referred to as the "inside"). Since the demolition work is carried out by disassembling the building on the opposite side of the building (hereinafter referred to as the "outside"), the parts removed by workers are lighter and the demolition work can be carried out more safely.
The inner curing sheet and the outer curing sheet are used as a pair, and the removal of the curing sheet is done by opening the overlapping part of the inner curing sheet and the outer curing sheet and moving the inner curing sheet and the outer curing sheet in opposite directions. This has the effect of ensuring that the center of gravity of the scaffolding is not biased and can be carried out safely.
Even in the event of a sudden change in weather, the part of the inner curing sheet that is superimposed on the back side of the inner curing sheet is pulled out from above the inner roof frame, and is extended over the roof of the building to cover the outer wall of the building, thereby protecting the outer wall of the building from rain. It has the effect of being able to

The inner and outer roof frame sections are paired with connecting pipes hanging down from the inner and outer main pipes that slope at the same slope, and the inner and outer main pipes are connected to form one roof frame. This has made it easier to assemble and dismantle the roof frame to the top of the external framework scaffolding. By having two curing sheets, an inner curing sheet and an outer curing sheet, with an overlapping part, and by folding the non-overlapping part of the inner curing sheet and placing it on the roof frame in advance, even in sudden rain. By simply pulling out the folded part of the inner curing sheet, extending it to the building roof, and spreading it to cover the building's exterior wall, we were able to protect the area from the scaffolding to the building roof from rain.

The roof frame for curing the external framework scaffolding will be explained based on FIGS. 1 to 3. The roof frame 1 for curing the external framework scaffolding mainly consists of an inner roof frame part 2 and an outer roof frame part 3 made of steel. The inner roof frame portion 2 includes an inner main pipe 4, inner connecting pipes 5, 6, and an inner guide pipe 7. The inner main pipe 4 is inclined upward toward the outside, and inner connecting pipes 5 and 6 are fixedly vertically provided on the lower surface thereof in a mutually parallel positional relationship. A downwardly inclined inner guide pipe 7 is connected to the inner end of the inner main pipe 4 via a curved portion. The outer end of the inner main pipe 4 is open. The lower end of the inner connecting pipe 6 is open and is formed so that it can be stably attached to the inner support 8 of the outer framework scaffold. One end of a chain 9 is fixed to the lower surface near the outer end of the inner main pipe 4 by means such as welding.

In the outer roof frame section 3, an outer connecting pipe 11 is vertically installed on the lower surface of an outer main pipe 10 that has the same slope as the inner main pipe 4 and tilts upward toward the outside, and a chain 9 is installed on the lower surface near the inner end of the outer main pipe 10. Chain fixing means are provided for removably attaching the other end. In this embodiment, a case is described in which a threaded rod 121 integrally hung vertically on the outer main pipe 10 is passed through a ring of the chain 9 as a chain fixing means and is tightened with a washer 122 and a nut 123. The invention is not limited to this. All means for fixedly attaching the other end of the chain 9 to the vicinity of the inner end of the outer main pipe 10 are included in the present invention. A downwardly directed outer guide pipe 13 is connected to the outer end of the outer main pipe 10 via a curved portion so as to be substantially parallel to the outer connecting pipe 11 . A pin 14 is provided on the outer surface of the outer guide tube 13 and extends downward so as to be parallel to the axial extension of the outer guide tube 13 . A fitting part 15 is continuously provided at the inner end of the outer main pipe 10. The fitting part 15 reduces the diameter of the inner end of the outer main pipe 10 and can be inserted into the inner main pipe 4 from the outer end opening of the inner main pipe 4 . When the fitting part 15 is inserted from the outer end opening of the inner main pipe 4 to connect the inner main pipe 4 and the outer main pipe 10, the axes of the inner main pipe 4 and the outer main pipe 10 are located on the same straight line, and the inner connecting pipe 5 The lengths of the connecting tubes 5, 6, and 11 are set so that the lower end of the inner connecting tube 6 is located on a line connecting the lower end of the outer connecting tube 11. The outer connecting pipe 11 is formed so as to be connectable with the outer support column 16 of the outer framework scaffold.

A rain protection device for external framework scaffolding will be explained with reference to the drawings. The roof frame 1 for protection is assembled by inserting the fitting part 15 from the outer end opening of the inner main pipe 4. The inner connecting pipe 6 is connected to the inner support 8 of the outer framework scaffolding, and the outer connecting pipe 11 is connected to the outer support 16. They are connected and attached to the upper end of the external framework scaffold at predetermined intervals along the width direction of the scaffold. A threaded rod 121 is inserted into the ring at the other end of the chain 9, and is fastened with a nut 123 with a washer 122 in between, to prevent the inner main pipe 4 and the outer main pipe 10 from opening in the outward and outward directions. In addition, a chain 17 that hangs downward at a midway position of the chain 9 is connected, and is wound and attached to a horizontal stiffener 18 installed between the upper ends of the inner support 8 and the outer support 16, so that the roof frame 1 for curing can be stabilized. The structure is designed to maintain the state of attachment to the scaffold.

The outer curing sheet 19 is made of a synthetic resin thin piece with impermeability, and is rectangular in plan view with a width longer than the left and right width of the external framework scaffolding, and has an inner edge as shown in FIG. A coupling member mounting hole 20 formed of an eyelet is provided at the outer edge, and a coupling member mounting hole 21 formed of an eyelet is provided at a position spaced apart from each other by a predetermined distance in the width direction. Connecting member attachment holes 22 made of eyelets are also provided at the left and right edges of the outer curing sheet 19. Triangular mounting pieces 23 are provided on the bottom surface of the outer sheet 19, with the apexes facing the inner edge and spaced apart from each other at a predetermined distance along the width direction, and vertical mounting pieces 23 spaced apart from each other at a predetermined distance in the inner and outer directions. They are arranged in two rows. As shown in FIG. 5, the mounting piece 23 has a ring mounting hole 24 formed of an eyelet. The mounting piece 23 is configured such that the inner side of the seat, which does not include the ring attachment hole 24, is not fixed to the seat bottom surface and is separated, and the outer side area, which includes the ring attachment hole 24, is integrally attached to the seat bottom surface. The ring 25 can be inserted from the bottom side of the seat to the bottom side of the mounting piece 23.

The inner curing sheet 26 is made of a synthetic resin thin piece with impermeability, and is rectangular in plan view with the same width and length as the outer curing sheet 19, and as shown in FIG. Connecting member attachment holes 27 made of eyelets are formed in the side edges at positions facing each other at a predetermined interval in the width direction.

The inner rope 28 and the outer rope 29 are made of wire ropes, and both ends of the inner ropes 28 and the outer ropes 29 are tightly tied between the vertical bars 30, 30 installed on the left and right ends of the external framework scaffolding, and are placed in substantially parallel positions on all the roof frames 1 for curing. The relationship is maintained and maintained. A rope winder may be provided at one end of the inner rope 28 and outer rope 29.

The inner bottom surface (back surface) of the outer curing sheet 19 and the outer surface surface (surface) of the inner curing sheet 26 have an overlapping part 31 that is overlapped vertically to cover the entire upper part of the external framework scaffolding on the curing roof frame 1. It is spread out. The outer curing sheet 19 covers the outer surface of the outer guide tube 13, and the outer edge of the outer curing sheet 19 is fixed by connecting a connecting member 32 made of a string passed through the connecting member attachment hole 21 to the pin 14. There is. A ring 25 into which an inner rope 28 is inserted is inserted into the ring attachment hole 24 of the attachment pieces 23 that are arranged in a row in the lateral direction on the inner side of the attachment pieces 23 attached in a row on the bottom surface of the outer curing sheet 19. are fitted and connected. A ring 33 into which the outer rope 29 is inserted is inserted into the ring attachment hole 24 of the attachment pieces 23 which are arranged in a row laterally on the outside of the attachment pieces 23 attached in a row on the bottom surface of the outer curing sheet 19. are fitted and connected. A non-overlapping portion of the inner curing sheet 26 that is not overlapped with the outer curing sheet 19 extends to the roof of the building 34. In addition, in preparation for sudden rainy weather, the non-overlapping portion of the inner curing sheet 26 is folded inward in a mountain direction and folded over the curing roof frame 1 in advance. Even in the event of sudden rain, a worker can reach down from below while standing on the topmost scaffolding board, pull out the folded unoverlapping part of the inner curing sheet 26, and throw it onto the roof of the building 34. This has the effect of protecting the outer wall of the building 34 from rain and allowing work to be done in rainy weather just as well as in sunny weather. The inner curing sheet 26 covers the area from the upper part of the scaffold to the inside, and the outer curing sheet 19 covers the part from the upper part of the scaffold to the outside, so when the upper part of the scaffold is opened. The ring 33 is removed, the inner curing sheet 26 is opened inwardly, and the outer curing sheet 19 is opened outward to eliminate the overlapping part 31, and the inner curing sheet 26 and outer curing sheet 19 are collected respectively, so that the scaffold does not tilt. There is. Since the curing roof frame 1 is constructed by combining two parts, the inner roof frame part 2 and the outer roof frame part 2, when assembling and disassembling work, either the inner roof frame part 2 or the outer roof frame part 3 must be assembled. Having one side has the effect of reducing the burden on the worker.
