【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、建築構造物の横葺き屋根構造に適用される
システム化された垂木装置に関する。Description: TECHNICAL FIELD The present invention relates to a systematic rafter apparatus applied to a thatched roof structure of a building structure.

〔従来の技術〕 一般に、金属材料を用いた屋根構造としては、従来から
縦葺き形式による屋根構造と横葺き形式による屋根構造
とがある。[Prior Art] Generally, as roof structures using a metal material, there have been conventionally a roof structure of a vertical-roof type and a roof structure of a horizontal-roof type.

するように所定間隔で平行に固定配置する。Each of these types has a relatively wide width on a main building material that is arranged parallel to the building direction of the roof structure that constitutes the roof structure surface (hereinafter also referred to as lateral direction) to give a predetermined roof slope. Plural rafter members that are narrow and long and have a flat support surface are orthogonal to the ridge direction (hereinafter also referred to as the vertical direction)
As shown in FIG.

Between each rafter member, in a state in which a plurality of the vertical roofing boards are arranged in the lateral direction in parallel, by engaging or fixing the members directly or by appropriately intervening an engaging member, the longitudinal direction is sequentially. Thatched up. Further, in the latter thatched roof structure, the eaves side engaging portion and the ridge side engaging portion which can be engaged with each other adjacent to each other in the longitudinal and lateral directions, and the lateral thatching roof plate having the face plate portion in the central portion are used. In a state of being supported across adjacent rafter members, a plurality of these thatched roofing plates are stepwise formed in a stepwise or sawtooth shape in the vertical direction so that they are engaged with each other, and Then, by appropriately using a suspension member to hold and fasten it, the roof is sequentially raised in the lateral direction.

基づき任意に選択して使用される。However, each structure of the conventional thatched roof and the thatched roof has merits and demerits in application to general building structures, and the intended use and surrounding environment of the target building structure, etc. It is used by arbitrarily selecting it based on each condition of (1) and request of appearance form.

な構造強度及び効果的な水捌け作用などに併せて、良好
な形態の外観意匠を得ている。Here, when comparing the horizontal thatched roof plate used for the horizontal thatched roof structure with the vertical thatched roof plate of the vertically thatched roof structure, the covering area range per individual roof plate relative to the roof surface is relatively large due to the structure. It is narrower, which reduces its effective width (that is, the length in the longitudinal and longitudinal directions, which corresponds to the roof width on the roof), thereby providing sufficient structural strength and effectiveness. In addition to its water-removing effect, it has a good appearance design.

覆面対応に狭くされているので、たとえ縦葺き屋根構造

A space is formed on the upper end side, and the corresponding face plate portion is likely to bend due to positive pressure applied from the outside. Therefore, in order to prevent this, the same side engagement portion is required for each step of thatching. It was necessary to insert a so-called backup material (wood wool cement board, urethane foam board, etc.) that backs up the upper end side of the, separately from the ground board as the base material.

Accurate setting of the pitching pitch requires a considerable amount of skill, and as a result of this, the number of work steps at the time of construction increases, including the need for a separate member, leading to cost increase. Was becoming.

棟側にかけて葺き上げることができる。As described above in detail, according to the present invention, in the rafter member applied to the thatched roof structure, the rafter member is arranged with a predetermined roof slope over each main building material, and the cross section is substantially U-shaped. A rafter member having a groove extending in the longitudinal direction and having locking hooks formed on the inner upper portions of the side walls on the left and right of the groove, and a roofing roof board supported on the upper surface, and , A face plate receiving and supporting portion in which a locking portion for locking the engaging portion of each of the side-by-side roofing plates adjacent to each other in the vertical direction is bent and formed on the eaves side, and both sides of the face plate receiving and supporting part are provided with side-roofing roofing plates. The length corresponding to the pitching interval of the roof and the inclination corresponding to the roofing inclination angle are made to face downward, and are detachably fitted in the groove portion of the rafter member at any position in the longitudinal direction and locked. Plural receiving / supporting locking members formed by projecting locking hooks that are locked and fixed to the fitting position by the hooks. Since the ridge-side engaging portion of the lower thatched roof board is locked by the locking portion of the upper-side receiving and supporting locking member, the upper-side receiving and supporting member After the stopper member is fitted into the groove of the rafter member, and the locking hook portion is engaged with the locking hook portion and fixed at the fitting position,
Engage the eaves-side engaging part of the upper thatched roof roof plate with the ridge-side engagement part of the lower thatched roof plate, and engage the central face plate part of the upper face side support member. It can be supported by the face plate receiving and supporting portion of the stop member, and by repeating this operation, the side thatched roof plate can be raised from the eaves side to the ridge side.
