Description

  The present invention relates to a roof plate support used for fixing a metal roof plate, and more specifically, even if the roof plate expands and contracts due to heat, it can move corresponding to the expansion and contraction to quickly absorb strain. It relates to a roof plate supporter.

  As such a roof plate support, a roof plate support in which a sliding member for locking the roof plate is slidably attached to an upper portion of a fixing member fixed on a base material has been proposed (see Patent Document 1). ).

  This roof plate support has a structure in which a fixing member and a sliding member are connected by a long hole and a shaft member that slides relative to each other in the long hole. The desired action / effect of removing the strain applied to the plate was achieved.

  By the way, although the roof has a gradient, it is not necessary to pre-grade the base material or the roof plate support itself to which the roof plate support is fixed, or the applied gradient is not accurate. It is preferable to configure the roofing plate support so as to cope with the required gradient.

  In the above-mentioned Patent Document 1, a technique for making it possible to cope with a gradient is disclosed in FIG. 7, but this structure is such that a hook-shaped auxiliary metal fitting that holds the lower part of a hanging member that fixes a roof plate can tilt. In this way, the lower surface of the holding portion located on the lower side of the auxiliary metal fitting held by the insertion of the bolt is curved upward and convex like the receiving portion at the upper end of the holding portion.

  However, in this structure, the portion facing the upper side surface of the auxiliary metal fitting is straight and not curved. That is, there is a space on the upper side of the auxiliary metal fittings even when the hanging member and the auxiliary metal fittings are not inclined, and the load due to the negative pressure must be countered only by the inserted bolts.

JP 2000-110307 A

  Accordingly, the main object of the present invention is to provide a roof plate support that can flexibly cope with a gradient and can increase the strength against a load, particularly a negative pressure.

  For this purpose, the roof has a fixing member fixed on the base material, and a sliding member attached to the upper portion of the fixing member and slidable in the front-rear direction as the fixed roof plate expands and contracts. A plate support, wherein a first receiving portion for receiving a roof plate or a sliding member and an upper side surface of a locking piece formed at a lower end portion of the sliding member and projecting in the left-right direction are received on an upper portion of the fixing member. It is a roof board support which forms a 2nd receiving part and curvedly formed these receiving parts in circular arc shape, It is characterized by the above-mentioned.

  That is, when it is necessary to tilt the sliding member when fixing the roof plate, the sliding member automatically tilts to obtain a desired inclination. When negative pressure is applied in the fixed state of the roof plate, first, an upward load is applied to the sliding member. At this time, the locking piece formed on the lower end portion of the sliding member is the second receiver formed on the fixing member. The load is applied to the part where the sliding member and the fixing member are slidably integrated, and the concentrated load is prevented from being applied.

  About the said 1st receiving part and the 2nd receiving part, Preferably, the 1st receiving part is curvedly formed convexly upward, and the 2nd receiving part is curvedly formed convexly downward. Tilt is possible even if the locking piece of the sliding member received by the second receiving portion is formed in a straight line which is the simplest shape.

  Further, a covering member that covers at least a part of the outer surface of the upper portion of the fixing member may be attached to the upper portion of the fixing member, which is a sliding member mounting portion, and the covering member may be formed of synthetic resin or rubber. By covering the portion that contacts the roof plate and the portion that contacts the sliding member with the covering member, it is possible to soften the contact between the metals, suppress the generation of unpleasant sound, and smooth the sliding operation. .

  Furthermore, when a fitting structure is formed between the covering member and the fixing member by the unevenness to prevent the vertical displacement between the covering member and the fixing member, the covering member and the fixing member can be simply fitted together. The unity in the vertical direction can be improved, and the assembly work becomes easy. Multiple fitting structures may be provided.

  The fixing member may be provided with leg portions opposed to each other with a gap, and a gap holding means for holding the shape of the fixing member may be provided between the leg portions. The interval holding means can be constituted by a holding member fixed between the leg portions, a holding piece integral with the leg portions, or an abutting portion that abuts each other.

  By providing the interval holding means, it is possible to increase the stability of the fixing member, to prevent deformation such as torsion, and to hold the gap between the leg portion or the upper portion of the fixing member as predetermined.

  Another means is a roof formed using the roof plate support.

  As described above, according to the present invention, the sliding member can be tilted by the first receiving portion and the second receiving portion provided on the fixing member. For this reason, it is possible to flexibly cope with the necessary slope of the roof at the site.

  And since the 2nd receiving part receives the upper surface of the latching piece formed in the lower end part of a sliding member, a negative pressure acted on the roof and the upward force acted on the sliding member In this case, in addition to receiving the load by the connecting means between the fixing member and the sliding member, the second receiving portion can also receive the load. For this reason, the intensity | strength of a roof-plate support tool can be raised, and a firm roof can be obtained by extension.
