Description

  The present invention relates to a cloth with a floor.

  The conventional cloth with floor (C) has a structure as disclosed in FIG. 1 of Patent Document 1 below, but since the cross-section is unknown, when this is shown in FIG. A rectangular flat steel plate having a width and a predetermined length is bent so as to form an L-shaped section (41) on the lower left side and an inverted L-shaped section (42) on the lower right side. The left and right main components (43) and (44) are formed in parallel, and the L-shaped portion (41) of the left main component (43) and the inverted L-shaped portion (42) of the right main component (44) are formed. ) Is made into a cloth material, and the horizontal part (45) between the upper edges of the L-shaped part (41) and the inverted L-shaped part (42) of the left and right main constituent members (43) and (44) is combined with the flooring material. Front and rear inner surfaces of the vertical part (46) of the L-shaped part (41) of the left main constituent member (43) and the vertical part (47) of the inverted L-shaped part (42) of the right main constituent member (44) Grab metal fittings (48) The mounting base portion (48a) is riveted, and the hook portion of the rear gripping metal fitting (48) is attached to either the left side surface or the right side surface of the hook portion (48b) of the front gripping metal fitting (48) as shown in FIG. (48b) is provided with a stopper (49) on the opposite side of the front grip (48), and a plurality of floor cloths (C) as shown in FIG. The center line of each floor cloth (C) is on the same straight line (l) and the hooks of the gripping metal fittings (48) facing the front and rear floor cloth (C) The boundary between the hook part (48b) and the mounting base part (48a) is bent outside the main components (43) and (44) to the side with the stopper (49) so that (48b) overlaps in the lateral direction. A steel front and rear beam member with a substantially U-shaped cross section, having notches (50) for protruding metal fittings at the left and right ends of the vertical portion (51). A plurality of back reinforcing steel strips (53) are fitted over and welded to the front and rear ends across the left and right main constituent members (43) and (44), and are further straddled across the lower horizontal portion of both cloth materials (52). Was passed in a zigzag shape and welded to each horizontal part of the L-shaped part (41) and the inverted L-shaped part (42). In addition, the plurality of back reinforcing steel strips (53) may be passed orthogonally so as to straddle the lower horizontal portion of both cloth materials.

  In this specification, the left means the left side of FIGS. 2 to 4, and the right means the right side of FIGS. 2 to 4.

  In the conventional cloth with floor (C), as described above, the L-shaped portion (41) of the left main component (43) and the inverted L-shaped portion (42) of the right main component (44) In addition, the horizontal part (45) between the upper edges of the L-shaped part (41) and the inverted L-shaped part (42) of the left and right main structural members (43) and (44) is combined to form a floor material. Grip brackets (48) are attached to the inner surfaces of both front and rear ends of the vertical portion (46) of the L-shaped portion (41) of the component member (43) and the vertical portion (47) of the inverted L-shaped portion (42) of the right main component member (44). Since the mounting base (48a) is riveted, the left and right and left and right grips (48) inevitably exist in a protruding manner at the four corners of the floored cloth (C).

  By the way, when arranging a plurality of cloths with floor (C) in the length direction through the arm lumber (16), at the four corners of the cloth with floors (C), the rear grip with cloths with front floor (C) The hook part (48b) of the metal fitting (48) and the hook part (48b) of the front grip metal fitting (48) of the cloth with the back floor (C) are overlapped on the left and right, but as shown by the chain line in FIG. When the hook portion (48b) on the (54) side is inclined outward as viewed from the plane, the following problem occurs.

  That is, unlike the arm wood whose both ends are welded to the support column, the arm wood (16) with the wedge (56) which is fitted from above into the socket (55) provided on the support column (54) at both ends is used. In this case, since the hook portion (48b) is inclined outward, the hook portion (57b) is positioned on the wedge attachment portion (57) at the end of the arm wood (16). ) Since it is larger than the diameter of itself, the hook portion (48b) does not fit into the wedge mounting portion (57) as shown in FIG. The same problem arises when the stopper (49) of the outer hook part (48b) is bent outward by rough handling of removing the hook part (48b) from the arm wood (16).

  In the previous example of the conventional example, since the grip metal fitting was arc welded slightly inward from the end of the beam member, such a problem does not occur even if the hook portion or the stopper is bent outward. It was. In addition, although not shown, in the case of a building for a mobile scaffold, the three floored cloths were hung on the upper front and rear horizontal members by grips so that they are closely arranged in the width direction without any trouble. In other words, the total width of the three floored cloths closely arranged in the width direction is smaller than the distance between the center lines of the pillars on both sides and larger than the length of the horizontal member, The distance between the outer gripping brackets on the floor cloths on both sides is smaller than the length of the horizontal member, and the three floor cloths are as described above. Was able to be hung on the front and rear horizontal members with a metal fitting. However, when arc-welding a metal fitting that is plated on a plated steel beam, the welded part is peeled off by heat treatment, so repair with a paint is necessary, and over time, the part will rust. There was a problem that it was often necessary to repair with paint. Therefore, in order to solve this problem, the welding of the grip metal to the beam member is abolished, and the vertical portion of the L-shaped portion of the left main component member and the reverse L of the right main component member as in the conventional example shown in FIG. The attachment base of the gripping metal can be riveted to the inner side surfaces of both ends of the vertical part of the shape part. As a result, the grip metal fittings are located at the four corners of the cloth with floor, which causes problems as in the case of using the above-mentioned wedge-armed armwood. If three floor cloths are arranged closely in the width direction, the distance between the outer grips on the floor cloths on both sides will be larger than the length of the horizontal member. They couldn't be handed over.

  Therefore, two cloths with floors are inevitably arranged side by side in the width direction, or one of three cloths with floors is arranged in a similar manner using one having a width approximately half the size. As a result, there is a part without a scaffold on the opposite side, and the inconvenience that it is impossible to place a paint container or the like that can be placed in any place on both sides on one side.

  Furthermore, since the conventional cloth with floor (C) has insufficient strength to resist torsion caused by the strong wind blown up due to its structure, it requires the back reinforcing steel strip (53) as described above. The weight increased, and labor and cost for welding the back reinforcing steel strip (53) were required.

  Although not shown in the figure, a rectangular flat steel plate having a predetermined width and length has a transverse cross-section L-shaped portion on the lower left side. Is bent to form a cross-section inverted L-shaped portion on the lower right side, thereby forming a main component member, and the L-shaped portion and the inverted L-shaped portion of the main component member are made into a cloth material, The horizontal part between the upper edge of the L-shaped part and the inverted L-shaped part is a flooring, and the floor cloth cloth (C) is placed on the inner surfaces of the front and rear ends of the vertical part of the L-shaped part and the vertical part of the inverted L-shaped part. A steel front and rear beam with a substantially U-shaped cross-section with a notch for protruding the gripping bracket at the left and right ends of the vertical section is attached to the mounting base of the gripping bracket that is bent and has a locking mechanism in the same manner as the gripping bracket. Fits and welds to the front and rear ends of the main component, and is the same as the reinforcing steel strip on the back of the cloth with floor (C) above. Was achieved back reinforcing steel strip was allowed welded to each horizontal section of the passed in a zigzag or orthogonally L-shaped portion and the inverted L-shaped section so as to straddle the lower horizontal portions of the fabric material.

  The same problem as the wide floor cloth (C) consisting of two main components except for the case of a narrow floor cloth made of one main component and a building for mobile scaffolding. Has a point.

The problem to be solved is that when the hook part of the gripping bracket is slanted outward or the stopper is bent outward, the hook part is It is not hooked because it hits the wedge mounting part at the end of the arm timber, which is larger than the diameter of the timber, so that the floor cloth cannot be put in place, and the floor reinforcing steel band for preventing twisting is attached to the floor cloth. It is in the point which requires the weight increase by welding, and the effort and cost of welding.
The object of the present invention is to be able to hook it to the arm wood with wedges even if there is the above abnormality in the gripping metal, and even without the back reinforcing steel strip, it can be reduced in weight as much as before without causing twisting, The object is to provide a floor cloth which is convenient for transportation and handling.
