Description

  The present invention relates to a cloth frame with a floor used to form a passage or a working floor of a temporary scaffold constructed at a construction site or the like.

  As a cloth frame with a floor used to form a passage or a working floor of a temporary scaffolding at a construction site, a floor material, a cloth material, and a beam material covering both ends of the floor material have been used so far. There has been used a member which is attached to the beam material or the cloth material, and which is composed of a pair of gripping metal pieces which respectively protrude in the length direction from both ends of the cloth frame (for example, Patent Document 1).

  Such a cloth frame with a floor holds the flooring material in a horizontal posture by hooking the gripping metal piece on a horizontal member provided on a column to form a passage or a working floor. Since it projects in the length direction, when the grip fitting is hooked on the horizontal member, a gap corresponding to the grip fitting is formed between the horizontal member and the beam, and the tool is inserted through the gap. There was a problem left in a place where it could not be said that safety was taken into consideration, as it could accidentally drop etc. or stumble upon walking.

  As a prior art to solve the above-mentioned problems, Patent Document 2 proposes a cloth frame with a floor having a structure in which an upper portion of a beam member is extended outward of a floor material portion. By the way, according to the cloth frame with floor proposed in Patent Document 2, the deformation of the gripping metal (impact load such as dropping is applied to the gripping metal fitting is inserted into a gap into which the gripping metal fitting of another adjacent fabric cloth with floor is inserted. It has a structure in which a reinforcing member for preventing (deformation due to) is incorporated separately, and it is inevitable that the number of parts will increase, and a process for assembling it will have to be newly added. It was difficult to efficiently manufacture the frame, and an increase in manufacturing cost was unavoidable.

The intermediate plate 8 has a function of preventing the floor plate member 1 from bending and the cloth plate member 2 from opening downward.

  In the cloth frame with floor according to the present invention, since the tip portion 3a1 of the upper flange 3a forming the beam member 3 extends toward the outside of the floor plate material 1, as shown in FIGS. In addition, no gap is formed between the horizontal member S and the beam member 3 which causes a tool or the like to fall or trip over when walking.

  Further, in the cloth frame with floor according to the present invention, as shown in FIGS. 8 and 9, the width direction end of the lower web 3c1 of the web 3c is always close to the inner wall portions of the gripping metal fittings 4a to 4d. Alternatively, since the contacting state is maintained, even if an unexpected impact load may be applied to the grips 4a to 4d by dropping the floor cloth, the impact load is applied to the entire web 3. Therefore, the deformation that falls into the inside of itself is suppressed. Therefore, it is not necessary to newly provide a reinforcing member or the like.

  When the widthwise end portion of the lower web 3c1 is arranged to be close to the inner side wall portions of the gripping metal fittings 4a to 4d, it is formed between the gripping metal fittings 4a to 4d from the viewpoint of avoiding the collapse deformation. The gap (t) is preferably within 1.5 mm (see FIGS. 8 and 9).

  When installing the inclined reinforcing member on the horizontal member S, the upper flange 3a of the beam member 3 is composed of the tip portion 3a1, the fixing portion 3a2, and the inclined portion 3a3, and the tip portion 3a1 is 5 mm larger than the fixing portion 3a2. Although it is preferable that the upper flange 3a is located in the upper position within the range, the upper flange 3a may have a flat upper surface as shown in FIG. 10 when the size of the inclined reinforcing member is small. By making the upper surface of the upper side flange 3a a flat surface, it is possible to eliminate stumbling (stumbling) during walking.

This is an example in which a standing piece 9 that stands up is provided.

  Since the standing piece 9 is located along the inner side wall of the grips 4a to 4d regardless of whether or not the upper end thereof reaches the upper flange 3a, an impact load acts on the grips 4a to 4d. However, a part of the impact load will be borne by the web 3c via the upright piece 9, and the impact load resistance performance of the grips 4a to 4d can be further enhanced.

  FIG. 15 is a developed view of the beam member 3 shown in FIGS. 13 (a) and (b) and FIGS. 14 (a) and 14 (b). The standing piece 9 can be formed by providing an extension 3d at a portion corresponding to the upper end of the lower web 3c1 and making a notch in the widthwise end of the extension 3d and the upper web 3c2. .

  16 (a) to 16 (c) are diagrams showing a beam material 3 according to still another embodiment of the cloth frame with floor according to the present invention, and FIGS. 17 (a) and 17 (b) are FIG. It is the figure which showed the external appearance perspective view of the right side (enlarged display) and right side of (b) about a part, and Drawing 18 (a) (b) shows the left side (enlarged display) and left of Drawing 16 (b). It is the figure which showed the external appearance perspective view of the surface about one part.

  In the cloth frame with floor having such a structure, one end is integrally connected to the lower web 3c1 at the upper end of the portion where the escape portion 5 is provided, one end is located on the inner wall portion of the metal fittings 4a to 4d, and the other end is upper. This is an example in which extension pieces 10a and 10b connected in a flush state are provided at the side ends of the web 3c2.

  Even in the case where the extension pieces 10a and 10b are provided, one end of each of the extension pieces 10a and 10b is always located on the inner side wall portion of the grip fittings 4a to 4d, so that an impact load acts on the grip fittings 4a to 4d. However, a part of the impact load is borne by the extension pieces 10a and 10b, and the impact load resistance performance of the grips 4a to 4d can be further enhanced.

  The extension pieces 10a and 10b may be formed by partially leaving the upper web 3c2 when providing the escape portion 5. Regarding the extension piece 10b, in this example, the cut portion c is provided at the edge portion along the inner side wall portions of the gripping metal fittings 4b and 4c that are bent.

  In the gripping metal fittings 4b, 4c, since the other gripping metal fittings 4a ', 4d' of the cloth with a floor arranged adjacent to each other are positioned on the outer side (outer wall side), the other of the widthwise direction of the web 3c. The ends can be brought close to or in contact with the inner side wall portions of the grips 4b, 4c, so that even if an impact load is applied to the grips 4b, 4c, the collapse deformation thereof is suppressed. .

FIG. 21 (a) and FIG. 21 (b) are views showing a part of the external appearances of the left side surface and the left side surface of FIG. 19 (b). .

  Such a cloth frame with floor has a slit S that is extended along the boundary between the web 3c and the lower flange 3b and is open at the end in the width direction. By forming the slit S, the web 3c or the lower flange 3b can be partially deformed even if a dimensional error or the like occurs during molding of the member. Assembling to cloth material becomes easy. As a result of structural analysis using FEM or the like, it has been confirmed that even if the slit S is provided, the deformation preventing effect of the gripping metal fittings 4a to 4d is not impaired, but the length of the slit S is It is preferable that W has the same length as the width dimension L of the relief portion 5.

  22 (a) to 22 (c) are diagrams showing another embodiment of the cloth cloth with a floor according to the present invention, and FIGS. 23 (a) and 23 (b) are right side surfaces of FIG. 22 (b). FIG. 24A and FIG. 24B are views showing a part of the external appearance of the left side surface (enlarged display) and the left side surface of FIG. 22B, respectively. It is a figure.

  Such a cloth frame with a floor is an example in which notches 11 are formed at both ends of the lower flange 3b in the width direction so as to form a gap between the grips 4a to 4d and the inner side walls. By forming the cutout portion 11, even if a dimensional error occurs during molding of the component member, the dimensional error can be absorbed, and the beam material 3 can be applied to the floor plate material 1 and the cloth plate material 2. This makes it easier to assemble and reduce the weight of the cloth frame with floor.

  The floor plate material 1 and the cloth plate material 2 which constitute the cloth frame with a floor are integrally formed by roll forming so that the gripping metal fittings 4a to 4d are fixed to the cloth plate material 2 by fastening means such as rivets, and then the beam. Although the material 3 is assembled and fixed to the floor board material 1 and the cloth board material 2 through a joining means such as welding, the members come into contact with each other even when an error occurs in dimensional accuracy in roll forming. Since it is not difficult to embed the beam material 3 into the floor plate material 1 and the cloth plate material 2, it is possible to efficiently manufacture the cloth frame with floor and improve the productivity. .

  According to the present invention, it is possible to eliminate the gap formed between the horizontal member and the beam member, and suppress the collapse deformation of the holding metal fitting without using an extra member such as a reinforcing member. You can provide a cloth frame with a floor to get.
