Description

  The present invention relates to a tight frame suitable for use in constructing a folded-plate roof widely used in large-area roofs such as factories, warehouses, and large stores.

  Folded plate roofing material is a product that is originally formed from steel sheet coils and formed into a desired shape and length using a roll forming machine installed at the construction site. Is widely used as a roofing material that can be economically secured.

  In general, this type of roofing material is provided with a suspension at the top of the tight frame, and the roofing material is fixed and held on the tight frame via the suspension. The tight frame that fixes and holds the roofing material has a large number of parts, takes time for construction work, and has a problem that the height of the roof is increased by the space for installing the suspension.

  In order to solve such problems, in recent years, a roof material mounting portion (which replaces the hanging body) provided integrally with the frame main body is provided on the upper portion of the frame main body of the tight frame, A so-called fitting type tight frame that hooks the latching portion of the roofing material and holds it to the attachment portion by winding the lower goby and the upper goby has come to be used.

  By the way, in the tight frame disclosed in the above document, the roof material is strongly pressed against the mounting portion when the lower gob and upper gob of the roof material are tightened. It has been pointed out that it may cause a bulging shape deformation, which impairs the aesthetics of the roof.

  In addition, when constructing a folded-plate roof, the folded-plate roofing material is temporarily laid on the tight frame. Therefore, the folded-sheet roof material temporarily laid with its weight may slip off from the roof material mounting portion as shown in FIG. 12 (the groove plate portion of the roof plate material and the mounting portion of the purlin etc. In general, there is a gap of 10 mm or more between), and there is a problem that efficient work cannot be performed.

  The object of the present invention is to realize efficient construction while avoiding local deformation of the folded-plate roof material that occurs when the lower gob and upper gob are wound together to join the roof materials together. A tight frame that can be made and has a simpler structure is proposed.

Is a tight frame for construction of folded-plate roof, characterized in that it has a top wall that supports the folded-plate roof material when the folded-plate roof material is held flat and flat.

  In the tight frame configured as described above, the locking member has a partition recess formed on the top wall leaving the edge region of the top wall, and the bottom wall of the partition recess is connected to the bottom wall. One or a plurality of apertures in at least one of the bottom wall and the peripheral wall connecting the bottom wall and the top wall to each other. It is preferable as a specific means for solving the problems of the present invention.

  According to the tight frame of the present invention, since the top surface of the top wall of the locking member that supports the folded roof material is horizontal and flat, when folding the lower goby and the upper goby, Since the contact pressure to the locking member is averaged and reduced as a whole, shape deformation of the folded plate roofing material can be prevented. In addition, even when the operator gets on the temporarily folded folded roof material when performing the tightening work, the top wall extends horizontally, so that the rotation of the folded roof material is suppressed. The folded-plate roof material does not slide down easily from the frame (locking member).
