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 carpenters to easily raise and lower the temporary roof.

  Furthermore, in the framed wall construction method house, the carpenter who constructs the floor and the outer wall often works alone, so after constructing the first floor, assemble the outer wall on the first floor, then the second floor After the construction of the floor, the work of moving the temporary roof for construction upward according to the number of construction floors is easy, as the work proceeds sequentially from the lower floor to the upper floor, such as assembling the outer wall of the second floor It was necessary to have a structure that could be used in
