Description

[Detailed description of the invention] [Field of industrial application] The present invention is a waterproof plate mounting anchor for welding in waterproofing construction related to waterproofing technology for roofs or walls of structures made of thin metal plates, especially stainless steel plates and titanium steel plates. It is related to.

[Conventional technology]

In recent years, for waterproofing building rooftops, factory roofs, general roofs, etc., seam welding methods using thin metal plates such as stainless steel plates or titanium steel plates have been replaced with conventional asphalt waterproofing, synthetic polymer roofing waterproofing, coating film waterproofing, etc. It has shown some effects such as extending the service life, shortening the construction period, and improving the waterproofing effect.

[Problem that the invention attempts to solve]

However, in the above seam welding method, Fig. 6 and 7
As shown in the figure, the compatible upper edges 51, 51 of the adjacent waterproof plates 50, 50 are aligned, and the rising edges 51,
Waterproof plate mounting anchor 5 made of thin metal plate between 51 and 51
Since the structure is such that the waterproof plate mounting part 53 of No. 2 is sandwiched, and the waterproof plate mounting part 53 is continuously welded together with the compatible upper edges 51, 51 by seam welding along the edges, the compatible upper edges The upper edge 51 is compatible with the side edge of the waterproof plate mounting part 53, and the part where the waterproof plate mounting part 53 is sandwiched between the parts 51 and 51 and the part where it is not sandwiched form a stepped state (see arrow P). , 51, resulting in a problem that waterproofness cannot be ensured.

In view of the above-mentioned problems, the present invention was developed for the purpose of ensuring waterproofness during welding construction, and the purpose is to provide a waterproof plate mounting anchor for welding in waterproof construction that does not form a step during welding. shall be.

[Means for solving problems]

The waterproof plate mounting anchor for welding in waterproofing construction of the present invention is used in the prevention construction where metal thin plates such as stainless steel plates and titanium steel plates are laid on the roof or wall of a structure, and is used at both edges of adjacent metal thin plates. Waterproofing that is located between the joint edges of thin metal plates that are joined together, and is pivoted to opposing locking grooves provided in a core that is fixed along the joint on the building frame side of the structure. In the plate-mounted anchor, both edges of the engagement base are pivoted to the opposing locking grooves of the core so as to be slidable in the groove direction, and a waterproof plate attachment portion made of a thin metal plate is attached to the engagement base. The tapered edge portions are provided on both sides of the rectangular strip-like edge of the waterproof plate mounting portion, and are arranged on the core wood at appropriate intervals, and are arranged on the core wood at appropriate intervals. The gist is to sandwich the waterproof plate attachment part between them, and to weld the two mating edges together continuously along the edges. Therefore, the welding described above can be performed by various types of welding, such as seam welding or plasma welding, and it is desirable that the edge end of the tapered edge portion be sufficiently thin.

[Effect]

In other words, the waterproof plate mounting anchor for welding in the above-mentioned waterproofing construction has a tapered edge portion in which the thickness of the waterproof plate mounting portion gradually becomes thinner toward both side edges when welding, and has an extremely thin wall thickness at the edge end. Therefore, there is no gap between the compatible upper edges at both ends of the waterproof plate mounting portion.

Therefore, reliable waterproof performance can be achieved in waterproof construction using thin metal plates.

〔Example〕

Hereinafter, one embodiment of the waterproof plate mounting anchor for welding in waterproofing construction of the present invention will be explained according to the drawings. Figures 1 and 2 show the waterproof plate mounting anchor, and Figures 3 and 4 show the seam welding. This shows an example of the construction method.

Reference numeral 1 denotes a core material made of aluminum extrusion molding, with both side walls 2, 2 having a grooved cross section.
Locking grooves 3, 3 extending in the longitudinal direction are formed facing each other on the inner surface of the top part, and through-holes 5 for attachment are bored in the bottom plate part 4 at appropriate intervals.
Further, the above-mentioned cross-sectional shape can be changed while maintaining the positions of both the locking grooves 3, 3, and reference numeral 6 indicates the diagonal bottom portion.

Reference numeral 7 designates a waterproof plate mounting anchor of the present invention, which is installed approximately at the center of an engagement base 9 formed by bending a rectangular waterproof plate mounting portion 8 of an appropriate width into a reverse groove shape. The above-mentioned waterproof plate mounting portion 8 has a plate thickness of 0.5 to 0.4, and has engaging protrusions 10 that are slidably engaged with the locking groove 3 in the longitudinal direction.
Gently thin tapered edge part 1 on both sides of mm
1 and 11, and has a wall thickness of 0.05mm or less at the edge.

The above-mentioned waterproof board mounting anchor 7 is constructed by embedding core wood 1 in grooves d formed in the waterproof surface of the construction body a in accordance with the width of the waterproof board 12, which will be described later.
Fixing members 6 such as anchor bolts from to the construction frame a
The locking groove 3 of the core wood 1 is installed or fastened.
3, and the engaging protrusions 10, 10 are engaged with the locking grooves 3, 3, respectively, so that the waterproof plate mounting part 8 is supported in a protruding manner on the surface of the construction frame a. After arranging a large number of waterproof plate mounting anchors 7 at appropriate intervals in this way, a rust-resistant metal thin plate (thickness 0.2 to 0.4 mm) such as a stainless steel plate or a titanium steel plate is laid from both sides of the waterproof plate mounting part 8. ) waterproof plate 12,1 consisting of
The rising edges 13 of 2 are aligned so as to sandwich the waterproof plate mounting part 8 to form an interlocking type, and the compatible upper edges 13, 13 and the vicinity of the upper edge of the waterproof plate mounting part 8 are continuous from one end. seam welding (seam welding trace M1)
It is constructed by fixed and integrated construction. It is preferable to use a self-propelled seam welding machine for seam welding.
The traveling direction is controlled along the rising edge 13, and welding is automatically carried out near the upper edge.

The waterproof board 12 has raised edges 1 perpendicular to the flat part 14 at both ends of the flat part 14 extending along the construction surface.
3, and the waterproof plate mounting portion 8 of the waterproof plate mounting anchor 7 is adjusted to the height of the rising edge 13.
height can be changed.

During the above-mentioned seam welding, the strip-shaped waterproof plate mounting portion 8 forms gently thin tapered edge portions 11, 11 on both side edges of the plate thickness of 0.2 to 0.4 mm, and at the edge end.
Since it is constructed to have a wall thickness of 0.05 mm or less, there is no gap between the compatible upper edges 13, 13 at both ends of the waterproof plate mounting portion 8.

Next, FIG. 5 shows an example of the plasma welding method. Similar to the seam welding method, the waterproof board mounting anchor 7 is engaged with the core wood 1 to support the waterproof board mounting part 8 in a protruding manner on the surface of the construction frame a,
