Description

  The present invention relates to an elevating stretcher for simultaneously raising and lowering a plurality of various materials such as columns, handrails, treads, brackets and the like of temporary scaffolds at a construction site between a high place and the ground.

  The temporary scaffolding at the construction site consists of a pillar that is vertically extended according to the height of the building, a pier fixed so as to straddle between the front and rear pillars toward the building, and It consists of a handrail fixed so as to straddle between the columns, a tread board spanned over the cross, and a brace if necessary. At both ends of the crosspiece and the handrail, wedges protruding in a direction perpendicular to the length direction thereof are provided, and the support column is provided with pockets corresponding to the wedges. Therefore, it is possible to assemble the column, the crosspiece and the handrail simply by inserting the wedge into the pocket while hitting it with a hammer.

  In order to raise and lower materials such as props between a high place and the ground, the workers placed on each floor are sent by hand one by one. Also, instead of such handing, a material transport lift has been proposed in which a rail is fixed to a previously installed support column and a box-shaped cargo bed containing a large number of materials is moved up and down while sliding on the rail (patent) Reference 1).

JP 2014-152467 A

However, it takes a lot of time and labor cost to send the support in the handing by the worker. Further, the material transport lift described in Patent Document 1 requires time for fixing the rails and also requires a large space for raising and lowering the loading platform, and thus cannot be applied to a narrow construction site.
Therefore, an object of the present invention is to provide a scaffold material raising / lowering stretcher that can be applied even in a narrow field without requiring a lot of manpower in a short time.

In order to solve the problem, the scaffold material lifting stretcher of the present invention is
Holds a variety of scaffolding materials including brackets, jacks, bases, brackets, and other short materials that are less than 70 cm long, as well as various scaffolding materials such as pillars, handrails, and treads, etc. It is a thing, Comprising: It is provided with a box, a pair of interruption | blocking cage | baskets, and a partition bar.

  The box has a square floor member, a vertical frame standing at each of the four corners of the floor member, a horizontal frame connecting the upper ends of the vertical frame, and a pair of wall members A and B. The portion is covered with the wall members A and B. The vertical frame and the horizontal frame may be made of a specially processed metal or may be a commercially available steel angle. The floor member and the wall member are usually made of a material lighter than the vertical frame and the horizontal frame, for example, plywood and aluminum plate. As described above, the box does not have wall members on the front and rear surfaces, and both side surfaces are covered with the wall members only on the both side surfaces, and thus are light overall.

  The barrier rods are attached one by one to the front and rear so that the long objects can be blocked from passing through the front and rear surfaces of the box in a standing posture. The barrier rod may be cantilevered by one of the vertical frames or one of the wall members so that a free end can swing in a vertical plane perpendicular to the wall members. It may be supported by both vertical frames that slide up and down while maintaining horizontal. In the case of the cantilever type, a stopper that can restrict the swinging of the free end is preferably provided on the opposing vertical frame or wall member. In the case of the double-sided type, it is preferable that stoppers are provided on both sides so that the blocking rod is stopped when necessary.

  The partition bar is cantilevered by the wall member A so that the free end can swing in a vertical plane perpendicular to the wall member, and the free end engages with the wall member B to take a horizontal posture. It can limit the movement of long objects in the front-rear direction. A plurality of partition bars may be arranged in parallel. Normally, the outer diameter of the pillars and handrails is larger than the thickness of other long objects such as treads, so the distance between the partition bars and the barrier rods and the distance between the partition bars is larger than the outer diameter of the pillars and handrails. A little bigger.

  When using the scaffold material lifting / lowering stretcher of the present invention (hereinafter also simply referred to as “stretcher”), the tip of the winch wire is connected to the upper end of the vertical frame or the horizontal frame. Then, with the rear shield bar closed and the free ends of all the partition bars attached to the wall member A, a long object such as a column, a step board, and a handrail is stood as far as possible on the floor member of the box. When the rear row is full, the free end of the innermost partition bar is hung on the wall member B and leveled. Subsequently, the long object is placed in the second row from the back, and when the same row is full, the free end of the second partition bar from the back is hung on the wall member B and leveled. In this way, packing is done in order from the back, and when the row is full, the dividers in the same row are leveled. When the floor member is full or the material to be lifted is interrupted, the front barrier is closed.

  According to the stretcher of the present invention, each row is filled with the material in the left and right direction, the front and rear surfaces are closed with a barrier, and in the front and rear direction, the partition bar is interposed for each row. Of course, there is no big inclination. Therefore, the entire center of gravity is stable and safe during elevation. Moreover, since a space with a flat area corresponding to the area of the floor member of the stretcher is sufficient for use, it can be lifted even in a narrow site. In addition, when unloading the material from the stretcher, the front shield bar may be opened and removed from the front surface, or the rear barrier bar may be opened and removed from the rear surface.

  One preferred configuration of the stretcher of the present invention includes an elastically stretchable band, one end of which is fixed to one of the two vertical frames sandwiching the wall member A, and the other end is free. Is. This attaches the free end of the unused partition bar to the wall member A, extends the free end of the band so as to straddle the partition bar, and fastens it to another vertical frame that sandwiches the wall member A. Thus, it is possible to prevent the partition bars that are not used during swinging from being shaken.

  In another preferred configuration of the stretcher of the present invention, a protective plate is further provided. The box has a guide extending in the vertical direction near the lower end of the adjacent vertical frame sandwiching the front surface and / or the rear surface, and the protection plate is detachable by sliding on the guide, Alternatively, it can cover the vicinity of the lower end of the rear surface. By providing a removable protective plate in this way, if you want to move up and down short materials and accessories such as brackets and jacks, you can attach the protection plate to the front and / or rear surface so that the short materials and accessories are It is possible to prevent sliding off from the floor member.

  In another preferred structure of the stretcher of the present invention, the box has a width of 50 cm or more and less than 55 cm, particularly preferably 53 cm or less. This is because, since the step board usually has a width of 50 cm, even if there is no space for raising and lowering the stretcher outside the scaffolding, the stretcher can be raised and lowered at that position by removing the step board.

  As described above, according to the present invention, if there is a ready-made winch without installing a rail and there is a work space corresponding to the area of the floor member in plan view, a plurality of scaffolding materials can be used with a small number of people. Can be lifted and lowered simultaneously.

It is the perspective view which looked at the stretcher of embodiment from the front. It is the perspective view which looked at the lower half part of the stretcher from the front of another angle. It is the perspective view which looked at the lower half part of the stretcher from back. (A) is an enlarged view of a partition bar attaching portion of the stretcher, and (b) is a BB sectional view in (a). It is an expansion perspective view near the stopper of the stretcher. It is a perspective view in the state where two long support | pillars are mounted on the stretcher. It is a perspective view in the state where two long columns, one tread board, and two short columns are mounted on the stretcher.

  The stretcher 1 can be lifted by a winch with various scaffolding materials including short-sized objects such as brackets, jacks, bases and brackets of temporary scaffolding and long-sized objects such as columns, handrails, and treads. , Box 2, two upper blocking rods 3a, two lower blocking rods 3b, six upper partition rods 4a, six lower partition rods 4b, and two protective plates 15a and 15b, Is provided.

  The box 2 connects a square floor member 5 having a width of 53 cm and a depth of 57 cm, a vertical frame 6 made of a total of four L-shaped angle steels standing at the four corners of the floor member 5 and the upper ends of adjacent vertical frames 6. It consists of a horizontal frame 7 made of a total of four L-shaped angle steels and a pair of aluminum wall members 8 and 9. The height of the box 2 is 2 m10 cm in outer dimensions. The peripheral edge of the floor member 5 and the vertical frame 6 and the horizontal frame 7 are on the ridge line of one rectangular parallelepiped, and the wall members 8 and 9 cover about five-eighth from below the opposite side surfaces of the rectangular parallelepiped. Are fixed to adjacent vertical frames 6. A steel suspension ring 7a is attached to the horizontal frame 7 so as to straddle the adjacent horizontal frames 7, and a wire W branched in four directions from the wire of the winch is connected thereto.

  The wall member 8 has two guides 8a projecting inward by 1 cm from the front and rear vertical frames 6 at intervals of 2 cm in the vicinity of the lower end. The guide 8a extends in parallel with the vertical frame 6 and has a length of 10 cm. The wall member 9 also has guides of the same shape and size at symmetrical positions. Further, as shown in FIGS. 2, 3, and 4, seven rectangular parallelepiped bearings 8b are attached to the inner surface near the upper end of the wall member 8 at equal intervals in the front-rear direction and penetrate the bearings 8b. One shaft 8c is fixed. Furthermore, seven bearings 8d having the same shape and size as the bearings 8b are similarly attached to the inner surface of the wall member 8 near the center in the height direction, and one shaft (not shown) passes through the bearings 8d. Is fixed.

  The wall member 9 has wooden bars 9a and 9b extending in the front-rear direction on the inner surface at a height facing the bearings 8b and 8d. The crosspiece 9a is provided with a concave portion 9c whose upper surface and inner surface are opened at the same pitch as the midpoint between the adjacent bearings 8b. A recess 9d is similarly provided in the crosspiece 9b. Further, corners between both end surfaces and the upper surface of the crosspiece 9a are cut off to form the same recesses with the vertical frame 6. The same applies to the crosspiece 9b. Accordingly, the crosspieces 9a and 9b have a total of eight concave portions 9c and 9d, respectively, together with the vertical frame 6.

  Three-eighth from the top of both side surfaces of the box 2, the entire top surface, and most of the front and rear surfaces are open. In this way, the box does not have wall members on the front and rear surfaces, the lower half portions of both sides are only covered with the wall members 8 and 9, and the wall members 8 and 9 are made of aluminum. So it is light overall.

  The upper blocking bar 3a is cantilevered by being loosely fitted to the shaft 8c near the corner where the front end edge and the upper end edge of the wall member 8 intersect. When not used, the free end of the upper blocking bar 3a is hung directly below the shaft 8c. When the upper blocking bar 3a is used, the free end of the upper blocking bar 3a is placed in the opposite recess 9c to maintain a horizontal posture so that the long object placed on the floor member 5 passes through the front in a standing posture. To block out of box 2.

  As shown in FIG. 5, an L-shaped stopper 11 a is attached to the vertical frame 6 near the front end edge of the wall member 9 so as to be swingable around the upper end of the L-shape. The L-shaped vertical bar portion of the stopper 11a has such a length that the lower end portion of the L-shape, that is, the free end reaches the opening surface of the recess 9c in the suspended state. When putting the upper blocking bar 3a into the recess 9c, the free end of the stopper 11a is raised. Then, when the free end is lowered in a state where the upper blocking bar 3a is placed in the recess 9c, even if the upper blocking bar 3a is lifted up slightly, the L-shaped vertical bar portion hits the stopper 11a, and the upper blocking bar 3a is pushed in the vertical direction. 3a is prevented from exiting from the recess 9c.

  The lower blocking bar 3b is cantilevered in the same manner as the upper blocking bar 3a near the corner where the rear edge and the upper edge of the wall member 8 intersect, and the long object placed on the floor member 5 passes through the rear surface. Thus, it can be blocked from going out of the box 2. Similarly to the stopper 11a, a stopper 11b is attached to the vertical frame 6 near the rear edge of the wall member 9 to prevent the lower blocking rod 3b from coming out of the recess.

  The six upper partition bars 4a are cantilevered by being loosely fitted to the shafts 8c between the adjacent bearings 8b. The interval between adjacent bearings 8b is sufficiently wider than the axial thickness of the upper partition bar 4a, and the upper partition bar 4a can slide in the front-rear direction within the same interval. When not in use, the free end of the upper partition bar 4a is hung directly below the shaft 8c. When the upper partition bar 4a is used, the free end of the upper partition bar 4a is placed in the concavity 9c that faces the upper partition bar 4a so that the long object placed on the floor member 5 is moved forward or backward. Restrict moving.

  The six lower partitioning bars 4b overlap with the six upper partitioning bars 4a in plan view, respectively, and are arranged at a half height of the wall member 8 on the shaft (not shown) in the same manner as the upper partitioning bar 4a. Cantilevered. When not used, the free end of the lower partition bar 4b is hung directly below the same axis. When the lower partition bar 4b is used, the free end of the lower partition bar 4b is placed in the recess 9d of the wall member 9 to maintain a horizontal posture so that the short object placed on the floor member 5 can be moved forward or backward. Restrict moving in direction.

  One end of one rubber band 13a is tied to the middle position in the longitudinal direction of the vertical frame 6 adjacent to the front end edge of the wall member 8, and the other end is free. 13b is attached. When there is an upper partition bar 4a that is not used, the free ends thereof are hung down and attached to the wall member 8, the free end of the band 13a is extended so as to straddle the upper partition bar 4a, and is close to the rear end edge of the wall member 8 By hooking the eaves 13b on the vertical frame 6, it is possible to prevent the upper partition bar 4a that is not used during swinging from being shaken.

  In addition, one end of another rubber band 14a is bound below the length of the partition bar 4a from the binding position of the band 13a in the same vertical frame 6, and the other end is free. A flange 14b is attached to the free end. The band 14a and the flange 14b are used in the same manner as the band 13a and the flange 13b in order to prevent the unused lower partition bar 4b from swinging.

  The protective plate 15a is made of a plywood having a height of 15 cm, a width of 50 cm, and a depth of 1 cm and 5 mm, and can be attached by sliding from the top to the bottom between the guide and the vertical frame 6 and can be removed by sliding in the opposite direction. . The same applies to the protective plate 15b.

  When using a stretcher 1 to lift or lower a long object such as a column, a step board, or a handrail, as shown in FIG. 6, close the rear shield rod 3a and hang the free ends of all the partition bars 4a and 4b. With the wall member 8 attached, a long object is erected on the floor member 5 as far as possible. When the back row is full, the free end of the farthest upper partition bar 4a is put into the recess of the wall member 9 to keep it horizontal. In FIG. 6, in order to avoid the drawing from becoming complicated, a state in which only two support columns are erected is illustrated.

  Subsequently, the long object is placed in the second row from the back, and when the same row is full, the free end of the second upper partition bar 4a from the back is put in the recess 9c to keep the level. In this way, packing is performed in order from the back, and when the row is full, the upper partition bars 4a in the same row are made horizontal. When moving a short object such as a short column, bracket, jack, etc., as shown in FIG. 7, the lower partition bar 4b and the lower shut-off bar 3b on which the short object is placed with the upper partition bar 4a suspended. Keep on. When raising or lowering small items such as tools, protective plates 15a and 15b are attached. When the top of the floor member 5 is full or the material to be lifted / lowered is interrupted, the upper blocking bar 3a and the lower blocking bar 3b in front are closed. In this state, the held material is raised together with the stretcher 1 by winding the winch wire. Since the box 2 is light, it can be raised only with the power of a ready-made winch.

  According to the stretcher 1, each row is filled with materials in the left-right direction, the front and rear surfaces are closed by the upper and lower blocking rods 3a, 3b, and the upper and lower partition bars 4a, 4b are interposed for each row in the front-rear direction. So, of course, the material will not fall down during ascent and descent. In addition, since the accessory is surrounded on all sides by the wall members 8 and 9 and the protection plates 15a and 15b, the accessory does not slide off from the floor member 5. Therefore, the entire center of gravity is stable and safe during elevation. Moreover, since a space with a flat area corresponding to the area of the floor member 5 is sufficient for use, it can be lifted even in a narrow site. In particular, since the width of the box 2 is 53 cm in the present embodiment, the stretcher 1 can be lifted and lowered at that position by removing a row of treads even in a place where there is no space for lifting the stretcher 1 outside the scaffold. In addition, when unloading the material from the stretcher 1, the blocking rod 3a may be opened and taken out from the front surface, or the blocking rod 3b may be opened and removed from the rear surface.

  The partition bars 4 a and 4 b are both cantilevered by the same wall member 8, but the partition bar 4 a is attached to the wall member 8 in order to make the center of gravity of the stretcher 1 being raised and lowered coincide with the geometric center as much as possible. The partition bar 4b is preferably cantilevered by the wall member 9. The suspension ring 7a is attached at a position away from the vertical frame 6 in order to avoid complicated drawing. However, even if the stretcher 1 rolls when the stretcher 1 is lifted, it is attached as close to the vertical frame 6 as possible in order to prevent the installed handrail from being caught between the suspension ring 7a and the vertical frame 6. Desirably, the suspension ring 7a may be eliminated and the wire W may be directly connected to the vertical frame 6. The blocking rods 3a and 3b may be both supported by the adjacent vertical frames 6 and slide up and down while maintaining the level.
