Description

  The present invention relates to a scaffolding board that serves as both a staircase and a ladder suitable for use in building roofs, construction of roofs of general houses, repair work, and other general construction / civil engineering works.

  Generally, when building or repairing a roof of a building or a general house, if the roof has a slope of an arbitrary angle, it is difficult for an operator to walk vertically and horizontally along the roof surface. The posture becomes unstable, the workability is poor, and in the worst case, there is a risk that the worker falls and falls to the ground.

  Therefore, as shown in Patent Document 1, a roof that prevents a worker from falling or falling to the ground during work while walking on the roof surface can be performed safely and prevent personal injury. Construction scaffolds have been developed.

This roof construction scaffolding includes an angle-adjustable rigid trap placed vertically on the roof surface in accordance with the slope of the roof surface, and an angle-adjustable handrail raised on one or both sides of the trap. The scaffolding plate is horizontally coupled to the side of the tarp via an adjustable scaffolding plate support bracket, and the handrail is erected on one side or both sides of the scaffolding plate. An operator walks and works.
Japanese Patent Laid-Open No. 2002-89033 (see drawings, claim 1)

  The conventional scaffold is not particularly defective in terms of function, but it is desired to improve the following problems.

  That is, the above-mentioned scaffold for roof construction is provided with a tarb along the slope of the roof surface and a scaffolding plate in an uneven direction provided on the side of the trap, so that when an operator walks along the slope of the roof Uses laps as stairs and ladders, and can use scaffolding boards when walking on the roof sideways.

  However, as described above, since the trapping and scaffolding plate having completely different structures are used according to the application, the number of parts increases, and there is a problem that design cost, processing cost, and material cost increase.

  In addition, when installing or removing the wrapping and scaffolding board on the roof, the weight and size of the two differ, making it difficult to pull up and pull down, making it difficult and disadvantageous to workability and cost. It becomes.

  In addition, when transporting laps and scaffolding boards to the construction site, the structure, weight, and size of the two are different, making it difficult to load them evenly on a truck, etc. .

  Furthermore, frame scaffolds are often installed at roof construction scaffolds and other general construction / civil engineering work sites, but the above-mentioned trapping and scaffolding boards cannot be used as scaffolding boards for this framework scaffolding as they are. .

  Therefore, an object of the present invention is to provide a scaffolding plate that can be used as a general scaffolding plate and can also be used for a staircase and a ladder as a trap and also serves as a versatile stairs and ladder.

  In order to achieve the above object, the means of the present invention includes a pair of opposing frames, a plate body constructed on the upper part of the frame, and an arbitrary gap between the pair of frames while facing the back of the plate body. It is characterized by comprising a plurality of steps erected at intervals.

  In this case, a pair of locking holes facing each other may be formed at both ends of the frame, and the frame and the plate main body may be provided along the longitudinal direction via a connecting member inserted into the locking hole. .

  Similarly, hooks may be provided at both ends of the frame body, and the hook body may be engaged with a horizontal rod to connect the frame body and the scaffold plate in the longitudinal direction.

  According to the present invention, the step is provided on the plate main body and the back side of the plate main body. Therefore, when the plate main body is arranged upward, it can be used as a normal scaffolding plate, and the step is turned upside down. Can be used as a staircase or a ladder.

  Therefore, it is not necessary to process the scaffold board and the ladder separately, so that the design, cost, and processing cost can be saved. In addition, when transported or stored by a truck or the like, it is possible to load evenly, prevent load slippage, and improve safety.

  Furthermore, the scaffold board of the present invention can be used not only for roof construction but also for general stairs, ladders and scaffold boards, and is versatile.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, a scaffold plate A that serves as a staircase and a ladder according to the present invention has a pair of opposing frame bodies 1, 1, a plate body 2 installed on the upper portion of the frame body 1, and a plurality of steps 3 installed at an arbitrary interval between the pair of frame bodies 1, 1 while facing the back surface of the plate body 2. It is characterized by that.

In addition, the frame body 1 and the scaffolding plate 2 may be provided continuously in the longitudinal direction.

  In more detail, the frame 1 is composed of a vertical plate 1a and upper and lower horizontal plates 1b and 1c integrally formed inside the vertical plate 1a as shown in FIG. Both ends are overlapped and fixed on the upper surface of the upper horizontal plate 1b, and both ends of Step 3 are fixed to the inner peripheral surface of the vertical plate 1a. Incidentally, this step 3 may be fixed on the lower horizontal plate 1c.

  The plate 2 is preferably made of a metal plate such as aluminum, a metal net such as plywood or expander metal, and the upper surface thereof is preferably anti-slip.

  Step 3 consists of cylinders or prisms made of metal, wood, synthetic resin with anti-slip surfaces, and is used as a reinforcing material when used as a scaffolding board, and when used as a staircase, ladder, etc. Used as a footrest for workers.

  When used in construction sites, for example, roof construction and repair, when the plate 2 is placed on the upper side, it is used as a scaffolding plate for the worker to walk, and when step 3 is placed upside down It is also used as a ladder, a stage where the operator moves up and down.

  For example, as shown in FIG. 3, when using as a staircase or a ladder for roof construction, the plate 2 is fitted on the roof surface B, and the step 3 is arranged upward.

  One or a plurality of scaffolding plates A are provided along the slope of the roof surface B, and a handrail or a protective net e is erected on one side or both sides of each scaffolding plate A. Also below each scaffolding plate A Another protective net D is provided so that when a tool, building material, or operator falls from above and slides down, they are supported and prevented from falling to the basement.

  Further, the scaffold plate A may be prevented from slipping off the roof surface B by preventing the frame 1 and the plate 2 from slipping, and as shown in FIG. You may make it suspend from the holding member above.

  The scaffolding plate A can be used alone, but according to the size of the construction site, for example, the area of the roof surface, a single scaffolding plate A may be connected in the longitudinal direction as shown in FIG. As shown in FIG. 1, locking holes 4 and 4 are coupled to both sides of the frame 1 so as to face each other, and two adjacent scaffolds A, using a connecting member 5 inserted into the locking hole 4 are used. It is preferred to bind A.

  For example, as shown in FIG. 4, the connecting member 5 includes a handrail mounting bracket 10, two rods 12 and 12 integrally connected to the handrail mounting bracket 10, and a stopper provided on the opposite side of the handrail mounting bracket 10. 16.

  In FIG. 4, the handrail mounting bracket 10 includes a pair of left and right hook pieces 17, 17, a pair of upper and lower support pieces 18, 18 extending to the front side, a socket 11 erected on the support pieces 18, 18, and a pair extending rearward. Rods 12 and 12.

  The stopper 16 includes a pair of left and right hook pieces 19 and 19 and a stopper piece 20 extending rearward.

  The rods 12 and 12 are inserted one by one into the locking holes 4 and 4 of the adjacent scaffolding plates A and A, and the adjacent frame bodies 1 and 1 are coupled to each other. 16, the rods 12, 12 are prevented from coming off by inserting the lock pins 23, 23 provided on the rods 12, 12 into the holes 21 of the stoppers 20.

  In this way, after the scaffold plate values A and A are coupled in the longitudinal direction, the handrail or the vertical support 7 of the protective mesh C is inserted into the socket 11, and the wire mesh 8 is raised on one side or both sides of the scaffold plate A.

  When connecting the wire or rope 9 to the scaffolding plate A, one rod 12 is inserted into the locking hole 4 of the uppermost scaffolding plate A, and the above wire or rope is inserted into the hole 22 of the one hooking piece 17 facing upward. What is necessary is just to insert 9 and couple | bond.

  5 and 6 show a scaffold plate A according to another embodiment of the present invention. This scaffold plate A is attached to both ends of the frame body 1 via brackets 31 so as to be rotatable, A pair of hooks 6 are attached to the bracket E.

  The bracket E is prevented from rotating during use by a stopper such as a pin 32 that is detachably inserted into the end of the plate 2. Other structures, functions, and effects are the same as those of the scaffold plate A in FIG.

  This scaffold board A is suitable for use as a scaffold board for a framework scaffold, and can also be used as a staircase or a ladder.

  As is well-known, a frame scaffold is one in which a plurality of vertical frames composed of vertical members and cross members are provided in the horizontal direction, and a scaffold plate is installed between adjacent building frames via the cross members.

  Therefore, the scaffold board A of the embodiment of FIG. 5 is used as a scaffold board by hooking the hook 6 on a horizontal rod as a cross member in the building frame.

  Then, when the bracket E is rotated, in other words, when the plate 2 is relatively rotated and the step 3 is directed upward, it is used as a staircase or a ladder.

  That is, as shown in FIG. 5, when the normal plate 2 is disposed upward, it is used as a scaffold plate, and at this time, the hook 6 is hooked on a cross member.

  On the other hand, as shown in FIG. 6, when the pin 32 is removed and the bracket E is rotated 180 degrees around the shaft 31 as shown by the arrow so that the plate 2 side is turned upside down, the step 3 is arranged upward. In some cases, it is also used as a staircase or ladder in a general work site.

  At this time, the hook 6 can maintain the same posture as that in FIG. 5 and can be hooked on other hooking members provided on the upper and lower sides of the construction site to prevent the entire hook 6 from slipping down.
