Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a base-isolated building tile structure that elastically supports at least a plurality of ridge tiles composed of a plurality of glazed roof tiles and round tiles to improve the earthquake resistance of the entire ridge tile.
[0002]
[Prior art]
The conventional roof tile structure is roughly divided into two types, wet and dry. Among them, the wet type is mainly a stack of roof tile members such as glazed tiles and round tiles using clay or plaster as a medium. As a result, the seismic problem arises, and the deterioration due to wind and rain is severe, and the ventilation of the building is not improved.
[0003]
Therefore, recently, building roof tiles made of glazed roof tiles, round roof tiles, etc. using various tightening fittings without using clay or plaster from the standpoints of lightening the building, improving earthquake resistance, and facilitating construction. Constructed dry-type products are becoming mainstream.
[0004]
However, even if the dry type can be made lighter than the wet type, the ridge tile is composed of glazed tiles, round tiles, face tiles, etc. that are stacked in multiple stages, and the weight of the component members themselves is inherently good, The roof tiles that are stacked in multiple stages are still one of the structures that are most likely to collapse in the event of an earthquake.
[0005]
Therefore, some improvements have been made so far in order to improve the earthquake resistance of dry type roof tiles. One of them is an earthquake-resistant structure in the building method disclosed in Japanese Patent Application Laid-Open No. 2-217555. However, what is shown in the gazette is a door tile, a large roof tile, a plurality of roof tiles, It has a structure in which round tiles are stacked, and these tiles are connected to each other by using a locking means to prevent the tiles from being displaced, and are connected and integrated using a fastener that penetrates each tile. is there.
[0006]
Japanese Patent Application Laid-Open No. 3-140549 also discloses an apparatus for a seismic ridge construction method, which, according to the description of the publication, incorporates a horizontal muscle frame such as a kind of spine in the building stack. In this case, the roof tiles are fixed upright on the purlin, and the roof tiles and crown tiles are fastened with thin metal wires to the frame of the horizontally long bars so that the displacement of each tile can be prevented against earthquakes.
[0007]
[Problems to be solved by the invention]
As described above, a dry type roof tile structure with improved earthquake resistance is known. However, all of these conventional seismic structures are designed to prevent the roof tiles from shifting due to vibration by linking and integrating the roof tiles with a fastener. It is not the one with the roof tile structure adopted.
[0008]
Therefore, in the case of the conventional ridge tile structure, the entire ridge tile with its own weight is directly subject to vibrations and shakes caused by earthquakes, typhoons, etc. In the case of a relatively large earthquake or typhoon, there is a problem that cracks or the like are generated in the firmly fixed portion and easily collapsed, and the same brittleness as wet is exposed.
[0009]
Therefore, the present invention provides a ridge tile having a considerable weight by elastically supporting at least a whole ridge tile composed of a plurality of glazed roof tiles and a round tile through a buffer member so that vibration is not directly transmitted to the ridge tile. The purpose is to provide a base-isolated building tile structure with improved overall earthquake resistance.
[0010]
[Means for Solving the Problems]
If the structure of this invention for achieving the said objective is explained in full detail, the invention which concerns on Claim 1 will connect the whole ridge tile which has a plurality of glazed roof tiles and round tiles via a buffering member in the upper part of a ridge tree. In a ridge tile structure that is elastically supported, a bolt っ た having a predetermined length is erected and fixed on the upper surface of a support substrate arranged on the upper part of the ridge, and a coil spring or a vibration isolating device is provided on the outer periphery of the bolt 杆. After the buffer member made of rubber is disposed, the through hole in which the tip of the bolt rod is drilled in the pedestal is penetrated, and the tip of the penetrated bolt rod is tightened with a nut, and the pedestal is elasticized by the buffer member. The base-isolated building tile structure is characterized in that a plurality of glazed roof tiles are appropriately stacked and fixed on the pedestal via a ridge core member, and a round tile is fixed on the upper surface of the uppermost glazed roof tile. is there.
[0011]
According to the first aspect of the invention, the entire roof tile having a plurality of glazed roof tiles and round roof tiles is elastically supported through the buffer member at the upper portion of the purlin, so that an earthquake occurs. Even if the building shakes, the vibration of the building body is absorbed well by the buffer member made of coil spring or anti-vibration rubber arranged on the outer periphery of the bolt cage, and the shaking is not transmitted directly to the roof tile member, It can prevent the roof tiles from collapsing.
[0012]
The invention according to claim 2 is characterized in that a flexible face door member is arranged between the lower surfaces of both ends of the pedestal and the flat roof tile, and a synthetic resin foam is placed in a space surrounded by the face door member and the pedestal. 2. The seismic isolation building tile structure according to claim 1, wherein the structure is filled.
[0013]
In the seismic isolation wing tile structure of the present invention, as described above, the ridge tile having a considerable weight as a whole is elastically supported through the buffer member made of a coil spring or vibration proof rubber. Even in the case of a large-scale earthquake, the shock is absorbed by the buffer member, so that the vibration is not directly transmitted to the roof tile, and the roof tile can be protected from collapse.
[0014]
In addition, when a flexible face door member is arranged between the lower surface of both ends of the pedestal and the flat tile, and a space surrounded by the face door member and the pedestal is filled with a synthetic resin foam such as polyurethane foam The cushioning properties are further improved and a good seismic isolation effect can be obtained. In addition, according to the present invention, the height of the entire roof tile can be adjusted by adjusting a nut that tightens the tip of the bolt rod penetrating the base.
[0015]
