JP4142729B2 - Wind and earthquake resistant flat roof tiles and roof tiles - Google Patents

Description

  In this invention, flat tiles are firmly fixed to the roof base, and the tiles that are struck when strong winds such as typhoons and gusts are not lifted and scattered from the roof base. In addition to being able to crawl at a gentle gradient without falling down, the surface after the tiles are crushed with a flat plate is only the level difference between the upper butt and the lower head in the direction of tile flow This is a flat roof tile that is flat with no step differences and uneven deformation, which reduces the risk of snowfall in a heavy snowfall area and simplifies the work. The present invention relates to a flat roof tile having a structure for securing strength and a structure for firmly fixing to a roof receiving bar.

  Various tiles have been devised to cope with unexpected flying strong winds, earthquakes, etc., and the tiles are floating up and down. No tiles can be found in the flat type with only the level difference of the current level, and in the example described in the reference, no other than actual application No. 3113832 can be found, and there are currently no level differences on the lifted surface. Asbestos slab flat tiles are used, but asbestos slab flat tiles are difficult to prevent scattering in the event of a disaster.

  In addition to the gentle slope to cope with snowfall in heavy snowfall areas, the raised surface of the tile is flat and the horizontal step and the unevenness of the tile surface are reduced only by the step in the running direction, making it easy to work There are no references to reduce the risk other than the actual application No. 3113832.

  In the actual application No. 2113832, the bottom tile's bottom end and the top tile's back surface are intertwined and connected to the top of the top tile with slanted irregularities, and the bottom tile's bottom is firmly fixed to the base tile receiving frame. However, in order to maintain and maintain the strength of the overlapping parts, the connection is applied by the L-type phase-matching method of the L-type with the top of the overlapped connection part in the side-by-side direction and the L-type with the bottom at the bottom. Since it is necessary to secure the mutual thickness of the lap joint at both ends of the roof tile in the horizontal direction, the lower end of the part to be overlapped with the L-shaped part is carved into the tile receiving pier, Necessity to ensure the strength of the thickness of the upper and lower parts.

Necessity to consider the contraction of roof tiles to warm and cold on the material of roof tiles.

Necessary to remove unnecessary parts other than securing strength in order to limit the weight of tile products to some extent.

  The connecting portion that engages the sloped convex part of the tip part of the bottom part of the lower roof tile in the flowing water direction described in Reference Document 1 with the sloped recessed part of the back surface of the head of the upper roof tile is the same as that document. In order to eliminate the unevenness of the surface when the tiles are rolled up in the horizontal direction and eliminate the level difference at the connection part, it is impossible to secure the thickness strength of the lap joint part unless the thickness of the entire tile is increased. Therefore, it is necessary to limit the overall thickness of the roof tile to secure the thickness of the joint portion in the lateral direction. Therefore, the lower end of the lower portion of the L-shaped end of the lateral joint is used as the upper end of the tile receiving bar. There is a need to ensure the thickness of the upper and lower portions of both end portions of the joint to be carved and overlapped.

  As described in Reference 1 above, it is necessary to prevent the tiles from lifting during a typhoon or an earthquake.Therefore, when attaching to the receiving bar, it is necessary to firmly fix the bottom of the lower tiles with screw nails. However, since the tile material is made of ceramics, ceramics, compacted cement, metals, etc., it is necessary to consider the measures against stretching during warm and cold conditions.

  An inclined convex part is provided at the tip of the bottom of the lower tile in the direction of running water, and an inclined concave part that sandwiches the convex part is provided on the back of the head of the upper tile, and the upper and lower roof tiles are firmly fastened. The bottom of the bottom tile is firmly attached to the tile receiving pier with flat head screw nails to prevent the tile from rising. In this case, the shape of the connecting portion in the direction of running water is described as inclined unevenness in the above Reference 1. If there is a shape that can be engaged with each other, it may be a companion S shape or a cono L shape.

  Since the basic material of the tile is shrinkable against warm and cold, when attaching the bottom of the tile to the tile receiving bar with screw nails, a funnel-type hard elastic rubber code 8 packing is sandwiched between them. Corresponding to the contraction.

  The upper surface of the tile is provided with several U-shaped guide grooves with a number 23 in the direction of running water to prevent splashing of the running water. The bottom surface of the lower roof tile is 10 mm above the tip of the upper tile head. A U-shaped groove with a reference numeral 24 is provided in the width direction to prevent backflow water.

  The lap joint at the tip in the horizontal direction 90 degrees transverse to the running water direction is connected to a phased joint with a width of about 5 cm to keep the top surface aligned, and has a thickness to maintain the strength of the tiles at the top and bottom of the joint. In order to keep it, the lower tile is L-shaped and carved about 10 mm thick on the lower tile receiving bar. The horizontal tip of the upper tile is about 10 mm wide and about 10 mm deep from the upper surface. As shown in 0010, the bottom of the roof tile is packed with silicon, and the bottom of the roof tile is covered with a rubber elastic packing to accommodate the warm and cold shrinkage of the roof tile. Therefore, a single U-shaped shallow groove with a width of about 15 mm is provided.

  The remaining portion 26 having a thickness of about 20 mm from the surface of the center portion of the back surface of the roof tile limits the weight of the scraped roof tile to some extent in the manufacturing process.

  In order to maintain the strength in the event of a disaster, the tile receiving sign 5 is firmly attached to the roof rafters and the ground while maintaining the standard strength of the Japanese cedar over 36mm square. At that time, it prevents the eaves from lifting up. For this purpose, the receiving bar code 6 has a thickness of 36 mm and a width of 90 mm or more.

  The number of earthquakes with high seismic intensity, with the bottom of the bottom tile fixed to the receiving frame and the bottom tile bottom and the top back of the top tile firmly connected to each other so that the roof tiles do not float and scatter in the event of a typhoon or gust There is no fear that the tiles will fall off due to large swings, and there will be no reverse water flow even when rolling at a gentle slope, and the flat type surface alignment is raised except for the step of about 20 mm between the upper and lower tiles. In addition, it is necessary to reinforce the structure of side-by-side joints and parts to be attached to the tile receiving piers in order to maintain and secure flat roof tiles for the purpose of making it possible to perform construction work without trouble in heavy snowfall.

  The horizontal joint is also an L-type phased joint of the upper and lower parts, maintaining strength and paying attention to water leakage, and the contraction of the warm and cold of the tile due to the action of the hard elastic rubber packing code 22 Also supports adjustment.

  In addition to the packing code 22 described in the above 0010, the screw nail code 7 for attaching the tile bottom part described in the above 0012 to the receiving bar is also provided with a funnel-type hard elastic rubber system for the shrinkage of the tile against warm and cold. The packing code 8 is sandwiched to adjust flexibly.
