JP 2013-194461 A

  Even in a temporary structure such as a temporary scaffold constructed using a plurality of columns without using a building frame, it is required to secure a large strength after construction. It is required to be secured with something that does not interfere with the operator who moves on the work cloth board supported by the robot.

  An object of the present invention is to provide a temporary structure that can secure the strength of the temporary structure without disturbing an operator who moves on a work cloth supported horizontally by a horizontal member. There is a place to provide a reinforcement frame for objects.

  The reinforcing frame of the temporary structure according to the present invention includes a plurality of columns, a horizontal member spanned between two adjacent columns among the columns, and the horizontal frame for an operator to ride. A temporary support structure reinforcing frame configured to include a work cloth plate horizontally supported by a material, and disposed horizontally between the two columns above the work cloth plate. A horizontal member, and two diagonal members each having an upper end coupled to the horizontal member and extending obliquely downward from the horizontal member in opposite directions. The horizontal member is disposed at both ends of the horizontal member. A first connecting member that is connected to the two struts on which the material is bridged is provided, and the horizontal member is suspended at the lower ends of the two diagonal members. Connected to the two struts being passed It is characterized in that the second connecting member is provided.

  For this reason, the reinforcing frame of the temporary structure according to the present invention has a horizontal member horizontally disposed between two struts on which a horizontal member is bridged, and an upper end portion of each of the horizontal members. And two diagonal members extending diagonally downward in opposite directions from the horizontal member, and a first connection that is connected to the two support columns at both ends of the horizontal member Since a member is provided and a second connection member that is connected to the two columns is provided at the lower end of each of the two diagonal members, the first connection member and the second connection member The reinforcing frame is attached to the temporary structure by the connecting member.

  Moreover, since this reinforcement frame has a horizontal member and two diagonal members, these horizontal members and diagonal members can fully secure the strength required for the temporary structure.

  In addition, the horizontal member is disposed horizontally between the two struts on which the horizontal member is bridged above the work cloth plate that is horizontally supported by the horizontal member for the operator to ride. The two diagonal members, each having its upper end coupled to the horizontal member, extend diagonally downward in the opposite directions from the horizontal member. Therefore, the reinforcing frame according to the present invention is placed on the work cloth board. It does not get in the way for a worker who rides and moves, and the worker can walk on the work cloth without worrying about the reinforcing frame, so that the operator can have good trafficability.

  In the present invention described above, the upper ends of the horizontal members are coupled to each other, and the two oblique members extending obliquely downward in the opposite directions from the horizontal member are connected to the upper ends of these oblique members in the longitudinal direction of the horizontal member. It is possible to connect to this horizontal member without a gap, or to connect to this horizontal member with a gap in the longitudinal direction of the horizontal member, and to cross these diagonal members. It is preferable that the upper end portions of the horizontal members are coupled to the horizontal member at intervals in the longitudinal direction of the horizontal member so that the oblique members do not intersect with each other.

  According to this, since it becomes possible to secure a space portion with a large height that reaches from the work cloth board to the horizontal member above the work cloth board on which the worker rides, the worker can use the work cloth board. The stiffening frame becomes even more unobtrusive when moving on top.

  Moreover, in the above invention, it is preferable to provide the connecting member for connecting these horizontal members and diagonal members for every diagonal member between a horizontal member and two diagonal members.

  According to this, since the strength of the reinforcing frame itself is further increased by the connecting member, the strength of the temporary structure reinforced by the reinforcing frame can be further increased.

  Further, in the present invention described above, the first connecting member for connecting to the two struts at both ends of the horizontal member, and the lower ends of the two diagonal members are used as the two struts. On the other hand, if the second connecting member for connecting to the support column can be connected to the support and can attach the reinforcing frame to the temporary structure, its form and structure The connection state may be fixed to the column or may not be fixed to the column.

  An example of such a connection member is a U-shaped or substantially U-shaped bracket member for fitting the column inside, and another example of the connection member is a pin that can be inserted into and removed from the column. .

  Further, when the connection member is a U-shaped or substantially U-shaped bracket member for fitting the support in the inside, at least one of the first connection member and the second connection member is used. It is good also as such a bracket member, and it is good also considering both a 1st connection member and a 2nd connection member as such a bracket member.

  Further, when both the first connection member and the second connection member are U-shaped or substantially U-shaped bracket members for fitting the struts therein, at least one of the connection members includes You may use the closing member for fixing the said support | pillar to the inside of the said connection member by horizontally crossing the opening part of a connection member and closing this opening part.

  According to this, the connecting member in which the closing member is used can be fixed to the support column by the closing member.

  In addition, such a closing member may have a horizontal distance to the support column that is constant in the transverse direction, but includes an inclined portion in which the horizontal distance to the support column continuously changes in the transverse direction. It is preferable to use a wedge-shaped member.

  According to this, the connection member is more effectively fixed to the support column due to the wedge effect of the wedge-shaped member.

  Furthermore, although the said closure member may be used for both a 1st connection member and a 2nd connection member, the width | variety of the horizontal direction of the opening part of one connection member among a 1st connection member and a 2nd connection member The dimension may be larger than the horizontal width dimension of the opening of the other connection member, and the closing member may be used only for the connection member having a large horizontal width dimension.

  According to this, since the number of closure members can be reduced and the length of the closure member can be increased as compared with the case where the closure member is used for both the first connection member and the second connection member, the closure member is a wedge member. Thus, the inclination angle for obtaining the wedge effect can be reduced, whereby the wedge effect can be realized more effectively.

  The above-described reinforcing frame according to the present invention can be applied to any temporary structure constructed using a work cloth board on which an operator rides at a work site such as a building or civil engineering. This is a temporary scaffold constructed at the construction site.

  According to the present invention, it is possible to secure the strength of a temporary structure such as a temporary scaffold without disturbing an operator who moves on a work cloth supported horizontally by a horizontal member. Can be obtained.

  Moreover, the upper end part of the two diagonal members 22 is couple | bonded with this horizontal member 21 with the space | interval of the longitudinal direction (wife direction B) of the horizontal member 21, and the two diagonal members 22 do not cross | intersect. .

  As shown in FIG. 3, the first bracket members 23 provided at both ends in the longitudinal direction of the horizontal member 21 are arranged in the spar direction A so that the columns 2A and 2B can be fitted therein. The first bracket member 23 has a closed surface portion 23A and both ends of the closed surface portion 23A in the wife direction B in the girder direction A. It consists of a pair of protruding surface portions 23B and 23C protruding. In addition, the second bracket member 24 provided at the lower end of each oblique member 22 also has an opening 27 that opens toward the beam direction A so that the columns 2A and 2B can be fitted inside. For this reason, the second bracket member 24 also includes a closing surface portion 24A and a pair of protruding surface portions 24B and 24C that protrude in the spar direction A from both ends of the closing surface portion 24A in the wife direction B.

As shown in FIG. 9, which is a cross-sectional view, the closing member 30 is inserted, and the closing member 30 horizontally crosses the opening 27 of the second bracket member 24 and closes the opening 27. By doing so, it becomes a member for fixing the pillars 2A, 2B to the inside of the second bracket member 24.

  FIG. 10 shows the closing member 30. The closing member 30 is formed by bending a thick plate. Therefore, the closing member 30 in which the girder direction A is the length direction includes a base portion 30A having a vertical width dimension, and the base portion. 30A is composed of a pair of flange portions 30B and 30C formed at the upper and lower ends of the column with a width dimension toward the columns 2A and 2B. Therefore, the vertical cross section of the closing member 30 is on the columns 2A and 2B side. It has a U-shape that is open toward it. Further, as shown in FIG. 9, the flange portions 30B and 30C each have an inclined portion in which the horizontal distance (the width dimension) with respect to the pillars 2A and 2B continuously changes in the transverse direction of the opening 27. Therefore, the closing member 30 is a wedge-shaped member as shown in FIG.

  Since the closing member 30 is a member having a U-shaped vertical cross section as described above, the holes 28 and 29 formed to insert the closing member 30 into the second bracket member 24 are provided. Of these, the hole 28 into which the closing member 30 is first inserted has a U-shaped vertical shape as shown in FIG.

  The closing member 30 may be a cast product, for example, instead of the above-described thick plate bent product.

  The work of attaching the reinforcing frame 20 according to the present embodiment to the temporary scaffold 1 shown in FIG. 1 is performed above the work cloth board 4 and the first connecting member, as can be seen from FIGS. The inside of the first bracket member 23 having a U-shaped horizontal section and the inside of the second bracket member 24 having the above-described second connecting member and having a substantially U-shaped horizontal section. The support members 2A and 2B are fitted to each other, and then the closing member 30 is inserted into the hole portions 28 and 29 out of the hole portions 28 and 29 of the second bracket member 24 and inserted into the hole portions 28 and 29. The member 30 is horizontally traversed by the opening 27 of the second bracket member 24, and the opening 27 is closed by the closing member 30. As a result, the pillars 2A and 2B are fixed inside the second bracket member 24. By this fixing, the reinforcing frame 20 is connected by the horizontal member 3 as shown in FIG. Thus, the strength of the temporary scaffold 1 is reinforced by the reinforcing frame 20 and sufficient strength of the temporary scaffold 1 can be secured.

  Before the reinforcement frame 2 is attached to the two support columns 2A and 2B, the closing member 30 is inserted into the hole portion 28 so as not to be removed in advance. You may make it perform the said operation | work for making the member 30 horizontally cross the opening part 27 of the 2nd bracket member 24 as an operation | work which inserts the closure member 30 in the hole 29. FIG.

  Further, according to this embodiment, the reinforcing frame 20 is attached to the temporary scaffold 1 in the wife direction B shown in FIG. 1, and the horizontal member 21 of the reinforcing frame 20 is located above the work cloth board 4. The reinforcement frame 20 is for a worker who rides on the work cloth board 4 and walks in the girder direction A because it is horizontally arranged between the two support columns 2A and 2B arranged adjacent to the wife direction B. It does not get in the way and it is possible to ensure good trafficability for the operator.

  Further, the work for bringing the first bracket member 23 and the second bracket member 24, which are the first connection member and the second connection member to the support columns 2A and 2B, into a connection state with the two support columns 2A and 2B, in other words, The work for fitting the support pillars 2A and 2B inside the brackets 23 and 24 has openings 26 and 27 in which the brackets 23 and 24 are opened toward the digit direction A. Therefore, the operator can easily perform the operation by holding the reinforcing frame 20 and moving the reinforcing frame 20 horizontally in the beam direction A with respect to the support columns 2A and 2B.

  Furthermore, in the present embodiment, as described above, the flange portions 30B and 30C of the closing member 30 continuously change in the horizontal direction with respect to the columns 2A and 2B in the transverse direction of the opening 27 of the second bracket member 24. Since the closing member 30 is a wedge-like member, the closing member 30 is squeezed to traverse the opening 27 so that the flanges 30B and 30C can be moved closer to the pillars 2A and 2B. The side surface comes into pressure contact with the columns 2A and 2B with a large load due to the wedge effect. For this reason, the 2nd bracket member 24 can be fixed to support | pillar 2A, 2B with a big intensity | strength, and the reinforcement frame 20 can be attached to the temporary scaffold 1 with a big intensity | strength.

  Further, the first bracket member 23 having a U-shaped horizontal cross section according to the present embodiment does not use the closing member 30, and the first bracket member 23 only fits the support columns 2A and 2B inside. Therefore, the number of closing members 30 that must be prepared can be reduced.

  In addition, the opening 27 of the second bracket member 24 in which the closing member 30 is used has a larger horizontal width than the opening 26 of the first bracket member 23 in which the closing member 30 is not used. Since the length becomes longer and the inclination angle for obtaining the above-described wedge effect of the closing member 30 serving as a wedge member can be reduced, the wedge effect can be realized more effectively.

  Furthermore, since the closing member 30 has two upper and lower flange portions 30B and 30C on the side in pressure contact with the pillars 2A and 2B, the pressure contact force against the pillars 2A and 2B is increased by deformation of the flange portions 30B and 30C. be able to.

  Further, in the reinforcing frame 20 according to the present embodiment, a connecting member 25 for connecting the horizontal member 21 and the diagonal member 22 between the horizontal member 21 and the two diagonal members 22 is the diagonal member 22. Therefore, the strength of the reinforcing frame 20 itself can be further increased by the connecting member 25. Therefore, the strength of the temporary scaffold 1 reinforced by the reinforcing frame 20 can be further increased.

  Further, two diagonal members 22, each having an upper end coupled to the horizontal member 21 and extending obliquely downward in the opposite directions from the horizontal member 21, each upper end of the diagonal member 22 is the longitudinal length of the horizontal member 21. Since the diagonal members 22 are coupled to the horizontal member 21 with a gap in the direction and do not intersect with each other, the work cloth plate 4 is disposed above the work cloth plate 4 on which the worker rides. Thus, it becomes possible to secure a space portion having a large height reaching from the horizontal member 21 to the horizontal member 21. For this reason, when the operator gets on the work cloth board 4 and moves, the reinforcement frame 20 is further obstructed. It can not be.

  INDUSTRIAL APPLICABILITY The present invention can be used for temporary structures such as temporary scaffolds that are constructed at work sites such as architecture and civil engineering using work cloths on which workers ride.
