Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of waterproofing work for waterproofing roofs, rooftop floors and basements of buildings, and preventing intrusion of groundwater and rainwater. The present invention relates to a method for laying asphalt roofing made of a material having excellent waterproofness, which is used as a waterproofing material when performing an asphalt waterproofing method. [0002] As is generally known, waterproofing works for waterproofing roofs, rooftop floors and basements of buildings, and preventing permeation of groundwater and rainwater mainly include:
There are two types of mortar waterproofing method and asphalt waterproofing method. The mortar waterproofing method is a method in which mortar containing a mixed waterproofing agent is applied to prevent water penetration. The asphalt waterproofing method includes a waterproofing layer consisting of a bituminous substance such as asphalt or coal tar pitch added with asbestos fiber, stone powder, mineral oil or sand to a thickness of 2 to 5 mm to form a waterproof layer. There is a membrane waterproofing method, which is a construction method for preventing the penetration of water by forming asphalt roofing, asphalt felt, and the like by melting asphalt. Generally, the waterproofing of the membrane is called asphalt waterproofing. The asphalt roofing used when waterproofing this asphalt is made of felt made from animal and vegetable fibers, with high extensibility, rich in sticking power, low in softening point, and infiltrated with liquid straight asphalt. Both sides are coated with solid or semi-solid blown asphalt having high heat resistance, low moisture sensitivity and low extensibility, high elastic impact resistance, and sprayed with mica or talc powder on the surface for excellent waterproofness. It is a member. This asphalt roofing is a long cloth-like member,
It is usually stored in a rolled form, and when used, it is spread out and used. As shown in FIG. 6, when waterproofing the roof of a building using the asphalt roofing 2, a predetermined width is overlapped from the eave to the ridge in a direction parallel to the eave of the roof.
Laying in layers. [0003] However, in the above-mentioned conventional asphalt roofing 2, the roof is laid in two layers in a direction parallel to the eaves of the roof from the eaves to the ridge with a certain width overlapping. When going, there is a problem that construction accuracy is lacking because the overlap width is hard to be fixed to a constant width. Further, if the construction is performed while measuring the width in order to keep a certain overlap width, a large amount of labor and time are required, so that there is a problem that the work efficiency is reduced. [0004] Means for Solving the Problems] The present invention has been made in view of the above circumstances, and has as its means, asphalt
Blown asphalt on a long felt
Width that extends in the longitudinal direction of the surface
And a center line for dividing the method into two equal parts.
On both sides, mark several gauge lines at equal intervals
And asphalt roofing of half the width of the line with asphalt roofing laid along the eaves edge of the roof, the direction parallel to the first sheet of the lines with bituminous waterproofing to cover all of the laid asphalt roofing against eaves And then lay a part of the second lined asphalt roofing along the center line of this first lined asphalt roofing or the gauge line located closer to the eaves than the center line, The asphalt roofing with a line is characterized in that the asphalt roofing with a line of the third sheet or less is sequentially laid in the ridge direction similarly to the second sheet. An embodiment of the present invention will be described with reference to FIGS. 1 to 5. Asphalt roofing 1 with a line used in this embodiment is, as shown in FIG. 1, an asphalt roofing 2 made of a long cloth-like member, and a surface which is one surface of the asphalt roofing 2. A center line 3 extending in the longitudinal direction and marked so as to divide the width dimension into two equal parts, and marked on both sides of the center line 3 in parallel with the center line 3 at equal intervals to each other. And the two gauge lines 4 formed. [0006] The asphalt roofing 2 is a long cloth-like member formed by covering both sides of a felt impregnated with asphalt with blown asphalt and spraying talc powder on the surface. The center line 3 is
The center of the asphalt roofing 2 in the narrow direction is marked in the longitudinal direction. Although the color of the center line 3 is not particularly limited, white, which has high visibility with respect to the black asphalt roofing 2, and green, which is inconspicuous from a distant position and has high visibility near, are suitable. The gauge lines 4 are marked in parallel at equal intervals on both sides of the center line 3. The color of the gauge line 4 is not particularly limited, either, as is the case with the center line 3, such as white which has high visibility with respect to the black asphalt roofing 2, green which is inconspicuous from a distant position, but has high visibility near, etc. Are suitable. FIGS. 2 to 5 show a method of laying the asphalt roofing 1 with a line on the roof according to this embodiment. An asphalt roofing 2 having half the width of the asphalt roofing with line 1 is laid on a roof board D on the side of the eaves C of the roof B of the building A in parallel with the eaves C of the roof B and along the eaves edge. A first lined asphalt roofing 1 is laid on the asphalt roofing 2 so as to cover the entirety of the asphalt roofing 2 in a direction parallel to the eaves C of the roof B. Then, along the gauge line 4 located closer to the eaves C of the roof B than the center line 3 of the first asphalt roofing 1 with the lines, the second asphalt roofing 1 with the line is moved to the eaves C of the roof B. And lay approximately half in parallel. Subsequently, a third lined asphalt roofing 1 is laid along a center line 3 of the second lined asphalt roofing 1 in a direction parallel to the eaves C of the roof B. The fourth lined asphalt roofing 1 laid next to the third lined asphalt roofing 1 laid along the center line 3 has a roof B higher than the center line 3 of the lined asphalt roofing 1.
Is laid along the gauge line 4 located near the eaves C of the eaves. As described above, while the process of laying the asphalt roofing 1 with the line along the center line 3 and the process of laying the asphalt roofing 1 along the gauge line 4 located closer to the eaves C of the roof B than the center line 3 are repeated,
From the eaves C to the ridge E one by one. The procedure for laying the asphalt roofing with line 1 is, as described above, merely repeating the step of laying the asphalt roofing with line 1 along the center line 3 and the step of laying along the gauge line 4. However, the present invention is not limited to this, and may be laid only along the center line 3 or only along the gauge line 4. Further, two or more gauge lines 4 may be marked on the surface of the lined asphalt roofing 1 at short intervals so that the overlapping width can be freely selected. As is clear from the above description, according to the present invention, asphalt roofing with a line is laid using the center line and the gauge line as marks, thereby improving the construction accuracy. In addition, since the construction is performed using the center line and the gauge line as a guide, the work is facilitated, labor and time can be saved, and the work efficiency is improved.
