Claims (6)

  1. A structure comprising: multiple support members (3); beam members (5, 6) spanning between the support members (3); longitudinal guide members (2) fixed along the support members (3) or along the beam members (5, 6); a material holding part (10) movable along the longitudinal direction of the guide member (2); and a brake device (30) that locks the movement of the material holding part (10) relative to the guide member (2) in the longitudinal direction.
  2. The brake device (30) comprises a pressing member (35) facing the guide material (2), a cam member (34) having a cam surface (34a) in contact with the pressing member (35), and an operating part (33) for rotating the cam member (34), wherein the pressing force of the pressing member (35) against the guide material (2) increases or decreases by the rotation of the cam member (34), as described in claim 1.
  3. The brake device (30) comprises a first elastic member (40) that biases the pressing member (35) away from the guide material (2), and a second elastic member (41) that biases the pressing member (35) in a direction that presses against the guide material (2), wherein the biasing force of the first elastic member (40) is set to be greater than the biasing force of the second elastic member (41), as described in claim 1.
  4. The material holding section (10) comprises a pair of receiving sections (16) extending horizontally to support the materials to be temporarily placed, a pair of main members (11) extending vertically to support the pair of receiving sections (16), and a connecting member (12) connecting the pair of main members (11). The structure according to claim 1, wherein the main member (11) or the connecting member (12) is provided with a traveling device (20) for rolling the material holding portion (10) in the longitudinal direction relative to the guide member (2), and a braking device (30).
  5. A material holding unit used in a structure according to any one of claims 1 to 4, comprising a material holding portion (10) that is movable along the longitudinal direction of the guide material (2), and a brake device (30) that locks the movement of the material holding portion (10) relative to the guide material (2) in the longitudinal direction.
  6. A temporary scaffold comprising the structure described in any one of claims 1 to 4, and including the support members (3) and the beam members (5, 6) or scaffolding boards (4) fixed to either of them.

Description

This invention relates to a material holding unit attached to a structure such as a temporary scaffold, and to a structure equipped therewith. Generally, temporary scaffolding is installed along the exterior walls of buildings and other structures, and is used by workers to carry out repair, painting, and other construction work. As shown in Patent Document 1, for example, temporary scaffolding has a structure in which pairs of support members are arranged in parallel in a direction perpendicular to the wall surface of the building, with these pairs placed parallel at predetermined intervals in a direction parallel to the wall surface. Beams connect adjacent support members in the direction parallel to the wall surface, and scaffolding boards are fixed to these beams. Alternatively, instead of fixing the scaffolding boards to the beams, beams may be placed across pairs of support members arranged in a direction perpendicular to the wall surface, and scaffolding boards may be fixed between adjacent beams in the direction parallel to the wall surface. Such temporary scaffolding is constructed by sequentially assembling materials (e.g., support columns, beams, scaffolding planks, and other necessary materials) upwards from a position close to the ground, until it reaches a predetermined height. These materials are lifted from a material storage area on the ground using cranes or similar equipment. Since lifting materials one by one is inefficient, it is common practice to lift a certain amount of material simultaneously and temporarily store it near the construction site. For temporarily storing materials used in the construction of temporary scaffolding, a material holding device, such as the one described in Patent Document 2, has been proposed.

In the following embodiments, the configuration of this invention will be explained based on an example in which the material holding section 10 is attached to a temporary structure 1 (hereinafter referred to as temporary scaffolding 1) installed at a construction site or the like. Figures 1 to 8 show a temporary scaffolding 1 equipped with a material holding section 10 (material holding unit U) according to the first embodiment, and Figures 9 to 10B show a temporary scaffolding 1 equipped with a material holding section 10 (material holding unit U) according to the second embodiment. As shown in Figures 5 and 6, the temporary scaffolding 1 consists of pairs of support members 3, 3 arranged in parallel in a direction perpendicular to the wall surface of a building or structure (hereinafter collectively referred to as "building, etc.") (hereinafter referred to as "one direction"), and pairs of support members arranged at predetermined intervals in a direction parallel to the wall surface (hereinafter referred to as "the other direction"). A beam member (horizontal member) 5 is placed between the pairs of support members 3, 3 in one direction, and scaffolding boards 4 are placed and fixed between adjacent beam members 5 in the other direction. In addition, adjacent support members 3, 3 in the other direction are connected by beam members (horizontal members) 6. Part of the beam member 6 is installed slightly above the scaffolding boards 4 and also functions as a handrail for workers. Furthermore, adjacent support members 3, 3 in one direction or the other direction are connected by diagonal members 7 that are inclined horizontally as needed, thereby increasing the rigidity of the structure. In addition, the scaffolding boards 4 may be placed between adjacent beam members 6 in one direction. The lower end of the support column 3 is resting on the ground via a height adjustment device. The height adjustment device allows for height adjustment of the support column 3 using a screw mechanism or similar to accommodate uneven ground and varying elevations. The support column 3, the unidirectional beam 5, the o
