Description

  The present invention relates to a temporary roof for protecting a site under construction of a frame wall construction method house from rain and direct sunlight in summer.

  When building a two-story house with a frame wall construction method (same for a three-story house), build the foundation first, then construct the first floor, then assemble the first floor outer wall, then 2 Since the 2nd floor outer wall is assembled after the floor is constructed, and the roof is installed at the end, if it rains at the construction site where the roof is not installed, the floors of the 1st and 2nd floors (plywood for construction) If rainwater accumulates and rains for a long time, such as the rainy season, the head part of the nail used to fix the structural plywood on the floor rusts and looks like a black ring around the nail There was a lot of complaints from the owners that the stains could cause water to accumulate on the floor, causing the trees to rot and cause problems with durability.

  In addition, when a large amount of rain falls in this way and a puddle is likely to be formed on the floor surface (structural plywood), the above problem has occurred. Although the floor and materials are covered so that the floor and materials do not get wet, workers must go to the site to drain the water collected in the blue sheet. It required a lot of time and effort, and was a cause of cost increase.

  In addition, on rainy days, the carried-in materials get wet and the quality deteriorates, so the work must be stopped. For this reason, when the construction was interrupted for a long time due to the rainy season, etc., the construction period was delayed, causing trouble with the owner.

  In addition, on summer days when sunlight is strong, the site under construction is surrounded by an outer wall and there is no roof, so the interior of the site under construction is exposed to direct sunlight and becomes hot, hindering carpenters' work. It was.

  For this reason, even in the midsummer day when the sun is strong, you can see that the carpenter works with a blue sheet eyelet and creates a shade using a single tube of the scaffold. There was a problem that the range was narrow and it took time to fix the blue sheet above the building under construction. In addition, complaints were received from neighboring houses because the blue sheet was blown by the wind and made a rattling noise.

  In summer and rainy days with strong direct sunlight, a temporary roof for construction may be installed on the site to prevent direct sunlight and rain.However, in the past, the entire building was covered with a simple structure, There was no temporary roof with a structure that allows a carpenter to easily build and wind up a temporary roof covering the work site by himself.

  In addition, in a framed wall construction method house, the building carpenter who constructs the floor and outer walls often works alone, so it is easy to build and wind up the temporary roof covering the work site alone. It was necessary to have a structure that could be done.

  In view of this point, an object of the present invention is to propose a temporary roof that can be built and wound on a temporary roof that covers the entire work site in a short time with a simple structure and with one person's labor. It is in.

As shown in FIG. 6 c, pipe rotating device 109 and pipe rotating device 105 are arranged outside the fixing PVC pipe 100 and the fixing PVC pipe 102 at both ends of the PVC pipe 90 on which the blue sheet 9 is wound in this way. The fixing PVC pipe 108 and the fixing PVC pipe 106 are attached to the outside by a set screw.

  7 is similar to the pipe rotating device rope 110 (the pipe rotating device rope 5 and the pipe rotating device rope 24) in the pipe rotating device 102 and the pipe rotating device 109 of the rotary sheet winding device 8 described in FIG. A state in which the rope is wound and passed is shown in a perspective view. FIG. 7 a shows the pipe rotating device 40 in a transparent shape with a one-dot chain line, and shows how the pipe rotating device rope 110 is wound around the PVC pipe 90 in one state. FIG. 7 b shows a state in which the pipe rotating device rope 110 described in FIG. 7 a is wound once by a solid line. The pipe rotating device rope 110 is inserted from the lower part of the roller 42 of the guide roller 39 described in FIG. 3, passes through the upper part of the roller 45 of the guide roller 38, passes under the nut 63, and passes through the PVC pipe 90. The guide plate 56 is guided by the curved end portion 55 of the guide plate 56 so that it is wound around the PVC pipe 90 from the left side of the base plate front direction 35 of the base plate 41 and passes under the nut 85 to guide it. After passing through the upper part of the roller 76 of the roller 37, subsequently passes through the lower part of the roller 73 of the guide roller 36.

  By pulling the pipe rotator rope 110 wound around the pipe rotator 40 in this way, the PVC pipe 90 rotates and the pipe rotator 40 is advanced in the direction in which the pipe rotator rope 110 is pulled. As described in 2, the blue sheet 9 of the rotary sheet take-up device, one end of which is fixed to the single scaffold pipe, is spread along the guide rope on the residential scaffold 1. The pipe rotating device rope 110 is configured to be in a loop between the three pulleys, the manual winch, and the pipe rotating device 40 as described in FIG. Installed in a stretched state without slack. The pipe rotating device 40 is attached to both ends of the PVC pipe, and the reason for pulling the pipe rotating device 40 with two separate pipe rotating device ropes is that the pipe rotating device rope 110 wound around the pipe rotating device 40 is When pulled, the pipe rotating device rope 110 may slip freely between the wound PVC pipe 90 and the rotary sheet winder moves forward without tilting. 40 is attached, and according to the progress of the left and right pipe rotating devices 40, the left and right pipe rotating device ropes 110 are separately pulled to uniformly spread the blue sheet 9 of the rotary sheet winding device. is there.

  Although the construction sheet roof (rope winding type) according to the present invention has been described in detail based on the above embodiment, the present invention is not limited to the above embodiment, and the gist of the invention Even if various modifications are made without departing from the scope of the invention, it is a matter of course that they belong to the technical scope of the present invention.
