[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a scaffold mainly used in a residential construction site.
[0002]
[Prior art]
Conventionally, steel scaffolds have been assembled along the perimeter of a building under construction.
[0003]
To explain the general configuration of the scaffold, the rear step installed along the outer periphery of the building, the front step installed every other step for the rear step, and attached between the rear step and the front step It is composed of a bracket, a bracket which is mounted in a cantilevered state on a rear step which does not have a front step, and a tread plate which is installed between the brackets.
[0004]
Here, in the conventional steel scaffold, the distance between the columns adjacent in the direction in which the scaffold extends is set to any distance that is an integral multiple of 0.3 m.
[0005]
On the other hand, in the case of a conventional wooden house, the distance between adjacent pillars is not regular but is set arbitrarily. In addition, even in the case of a house using mass-produced lightweight steel framed columns, the distance between the framed columns is set to 0.303 m, which is an integer multiple of a so-called traditional length.
[0006]
[Problems to be solved by the invention]
By the way, when assembling the scaffold described above on such a construction site of a house, the distance between the pillars of the scaffold and the distance between the pillars of the building are different from each other. It was difficult to make the length of the scaffold along the direction equal. Therefore, since it is difficult to adjust the length of the scaffold in the direction along the side of the building to a desired length according to the length of the side of the building, when assembling the scaffold around the building, It has been difficult to make the distance between the inner surface of the tread and the outer wall panel constant. Further, since the distance between the pillars and the distance between the pillars of the building are different, the front step may be accidentally positioned at a position facing the pillar or at a joint of the outer wall panels.
[0007]
If the distance between the inner surface of the tread and the outer wall panel cannot be made constant, a place wider than the desired distance and a place narrower on the contrary will occur, but in a place wider than the desired distance, the worker falls from the tread. Therefore, it is necessary to take measures to prevent falling. On the other hand, at a portion narrower than the desired interval, it becomes difficult to perform joint processing at the joint of the outer wall panels. In addition, when the front step is located at the joint of the outer wall panel, joint processing at the joint of the outer wall panel becomes considerably difficult.
[0008]
Therefore, in order to solve these problems, an allocation pattern table indicating how to arrange the pillars of the scaffold may be used depending on the shape and size of the building. It is difficult to create such an allocation pattern table, and there is a problem that the use of such an allocation pattern table itself is troublesome.
[0009]
The present invention has been made in view of these circumstances, and an object of the present invention is to easily perform joint treatment and the like at a joint portion of an outer wall panel, and to prevent a fall from a scaffold from taking measures to prevent a tread plate from being provided. An object of the present invention is to provide a scaffold in which a distance between an inner surface and an outer wall panel is constant.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the scaffold of claim 1 is configured such that a distance between adjacent framed pillars of a framed pillar constituting an outer peripheral portion of a building is set to any one of integral multiples of a predetermined module, such setting module exterior wall panel is mounted on the outside of the set framing columns, joints between the outer wall panels Oite the building under construction that is arranged to face the framing pillars of the building A scaffold that is assembled along the entire circumference and is referred to as a front strut located on the building side, a strut located behind the front strut as viewed from the building, and both a front strut and a rear strut. The bracket consists of a bracket that is attached to the rear, a cantilever attached to the rear step, and a tread that is supported on the bracket, and the distance between the adjacent front steps and the rear steps in the extending direction of the scaffold is , Mentioned above Is set to an integral multiple of the same module as set pillar distance adopted modules between at least front step is, in one every other stepping back and shifted so as not to face the junctions between the outer wall panels It is arranged , and furthermore, at each corner of the building, a strut which also functions as a front step and a rear step is arranged .
[0011]
Here, the module referred to in the present invention refers to a unit dimension that is a standard in architectural design, and includes, for example, a meter module of 0.5 m and a scale module of 0.303 m. May be the unit size.
[0012]
According to this configuration, the pillars that constitute the scaffold are arranged in the direction in which the scaffold extends, around the building in which the distance between the adjacent framed pillars is set to any distance that is an integral multiple of the predetermined module. However, the arrangement employs the same predetermined module as the predetermined module applied for setting the distance between the framed columns. According to this, as shown in FIG. 8, which is a plan view schematically showing the assembled state of the scaffold and the arrangement state of the framed columns of the building, the front step 3a and the rear step 3b, which are a set of columns, if staggered by a distance d ₁ in the extending direction of the scaffold, other post located on the extension direction will be staggered by the same dimension d _1.
[0013]
By making use of this point and shifting each of the pillars of the scaffold, each of the pillars is shifted by the same dimension, and the shift amount of each of the pillars is easily controlled. Therefore, the front step 3a of the scaffold does not face any of the framed columns 1, and the work on the joint portion of the outer wall panel performed at the position facing the framed column 1 can be easily performed.
[0014]
In the scaffold according to claim 2, in the scaffold according to claim 1, a scaffold equal to the length of each side of the building is assembled, and a scaffold having a predetermined length is provided for each corner of the building. Assembled, the interval between the inner surface of the tread placed on the scaffold and the outer wall panel is configured to be constant over the entire circumference of the building.
[0015]
According to this configuration, the distance between the adjacent framing columns is set to any integer multiple of the predetermined module, and the adjacent struts in the extending direction of the scaffold are applied to the setting of the distance between the framing columns. Are arranged based on the same predetermined module as the predetermined module.
[0016]
This makes it easy to assemble a scaffold having a length equal to the length of the side of the building, as illustrated in FIG. That is, the relationship between the dimensions of the building A and the scaffold B assembled therearound is a ₁ = b ₁ , a ₂ = b ₂ . Assembling such a scaffold moiety, further, for each corner of the building, by assembling the scaffold portion of the length b _7, and the inner surface of the footboard placed on the scaffold, the sides of the building opposite to the surface the distance d ₂ between can be made constant. The distance c between the front stepping and the rear stepping is constant. In this figure, the gap between the building A and the scaffold B is indicated by oblique lines.
[0017]
In the present invention, taking advantage of this point, the distance between the inner surface of the tread plate and the outer wall panel is made constant. For example, by setting this distance to about 0.2 m, joint processing at the joint portion of the outer wall panel is facilitated. And it is not necessary to take measures to prevent falling from the scaffold. Therefore, it is possible to provide a scaffold having both workability and safety on the scaffold.
[0018]
Although FIG. 6A shows a case where the scaffold of the present invention is assembled along a building whose corners are all corners, application of the scaffold of the present invention is not limited to this example. . For example, when assembling a scaffold along the periphery of a building having a corner, the scaffold may be assembled as shown in FIG. 6B or FIG.
[0019]
That is, in FIG. 6B, scaffold portions having the same length as each side are individually assembled along each side of the building. In the drawing, a ₁ = b ₁ , a ₂ = b ₂ , a ₃ = b ₃ , a ₄ = b ₄ , a ₅ = b ₅ , and a ₆ = b ₆ . Further, with respect to the two external corner portions other than the outer corner portion adjacent to the inner corner portion, by assembling the scaffold portion of the length b _7, the inner surface of the tread plate, the side of the building opposite to the surface it can be the distance d ₂ constant.
[0020]
On the other hand, in FIG. 7, the scaffolding portions having the same length as each side are individually assembled along each side of the building, and the building is extended to the outside corners other than the two outside corners adjacent to the inside corner. Te, assemble a scaffold portion of the length b _7. Then, a scaffold having a square shape in the drawing is assembled between the scaffolds assembled along two sides sandwiching the corner. Further, by making the heights of the sections P and Q different from each other, although the treads overlap each other at one point R, the distance d between the inner side surface of the treads and the side of the building facing the surface is set. ₂ can be constant. Note that the difference in height here is usually about 5 cm, so that the steps can be performed on the scaffold assuming that the treads are on the same plane.
[0021]
Here, the invention according to claim 3 is provided with a fall prevention fence for preventing the fall from the roof, and the fall prevention fence is such that the distance from the eaves of the roof is constant over the entire circumference of the building . It is attached to the rear step of the scaffold via a bracket having a different length .
[0022]
As described above, according to the third aspect of the present invention, since the distance between the pillar of the scaffold (the rear step 3b) and the outer periphery of the building can be made constant, the fall prevention fence 32 attached to the rear step can be used. It is also easy to keep the distance from the eaves constant.
[0023]
For example, when the distance between the outer periphery of the building and the eaves of the roof is constant, if the same length is used for the brackets 30 and 31 provided side by side in the drawing in the direction perpendicular to the plane of the drawing, the fall prevention fence is used. 32 and the space between the eaves can be made constant. Even when the distance between the outer edge of the building and the eaves of the roof is not constant, a bracket having a difference in length corresponding to the difference in the distance between the outer edge of the building and the eaves of the roof is used. For example, the distance between the fall prevention fence 32 and the eaves can be made constant.
[0024]
The invention of claim 3 makes use of this point to keep the distance between the eaves of the roof and the fall prevention fence 32 constant. For example, by setting this distance to 0.3 m, it is possible to temporarily fall from the roof. Even then, the fall prevention fence can be easily grasped, so that the work on the roof can be safely performed.
[0025]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0026]
FIG. 1 is a schematic plan view showing an embodiment of the scaffold of the present invention, showing about half of a scaffold assembled along a building and its periphery, and FIG. 2 is a side view of the scaffold of FIG. FIGS. 3A and 3B are cross-sectional views showing corners of a building for assembling the scaffold of the present invention. FIG. 3A shows an outgoing corner of the building, and FIG. 3B shows an inset corner of the building.
[0027]
This embodiment shows a case where a scaffold is constructed along the outer periphery of a building. As an overall configuration of the scaffold assembled along the outer periphery of the building, for example, an embodiment as shown in FIG. 6A or 6B can be considered. FIG. 1 is the same as that shown in FIG. 6A, but the lower part is omitted because the upper part and the lower part are point-symmetric with each other in the drawing. As shown in FIG. 1, the framing columns 1 of the building are arranged every 1.5 m or 2 m, and a scaffold is constructed around these framing columns 1. The tread 2 of the scaffold of the present invention has a length of, for example, 2.0 m, 1.5 m, 1.0 m, and a width of, for example, 0.4 m. Since the pillar 3 of the scaffold supports the tread 2 via a bracket arranged at right angles to the outer surface of the building, the length of the tread 2 is equal to the distance between the adjacent pillars 3. The support 3 of the scaffold is composed of a front step 3a (not shown in FIG. 2) located on the building side and a rear step 3b located behind the front step 3a. In supporting the two treads 2, if four pillars are used to support the treads 2, even if a person rides on the treads 2, one of the longitudinal ends of the treads 2 is attached to the rear tread 3b. The other end is supported by brackets attached to both the rear step 3b and the front step 3a. Therefore, every other front step 3a is arranged with respect to the rear step 3b.
[0028]
Next, a characteristic configuration of this embodiment will be described. The frame columns 1 constituting the outer peripheral portion of the building on which the scaffold is assembled are arranged at a distance of 1.5 m or 2.0 m which is an integral multiple of the meter module. . On the other hand, the rear steps 3b constituting the scaffold are arranged at a distance of 1.5 m or 2.0 m, which are also integral multiples of the meter module, adjacent to each other. Then, the distance between the adjacent framed columns 1 and the distance between the adjacent rear steps 3b are equal in the facing portions.
[0029]
Here, the front stepping 3a and the rear stepping 3b are each displaced from the neighboring frame 1 by 0.2 m in the extending direction of the scaffold.
[0030]
The description of the characteristic configuration up to this point is that of a portion of the scaffold that is assembled along a portion other than the corner of the building. Next, a portion of the scaffold assembled along the corner of the building will be described. In a portion of the scaffold assembled along the corner of the building, the distance between adjacent rear steps 3b is set to, for example, a distance of 1.0 m.
[0031]
Here, the strut 40 has a function of stepping forward and a function of stepping back. For example, the right column 40 functions as a front step for supporting the step board 25 in the vertical direction in the drawing, but functions as a rear step for supporting the step board 26 in the horizontal direction.
[0032]
In such a scaffold, each front step 3a is disposed at a position shifted by 0.2 m from the neighboring framed column 1, so that the front wall 3a Joint processing and the like can be easily performed.
[0033]
Further, as shown in FIG. 2 which is a side view of the scaffold of FIG. 1 and FIG. 3 (a) which is a cross-sectional view showing the vicinity of a protruding corner of the building, the rear step 3b is connected to the back surface 1a of the framed column. Are arranged so that the distance f is 0.8 m, the framed column 1 has a thickness w of 60 mm, and the outer wall panel 4 has a thickness of 35 mm. The distance e between the outer surface 4a and the inner surface of the tread plate 2 is 206 mm (<300 mm), so that it is not necessary to take measures for preventing the fall. In addition, the two-dot chain line N1 shown in FIGS. 2 and 3 (a) indicates a surface passing through the back surface 1a of the framed pillar, and serves as a reference surface when constructing a scaffold. Further, the distance A shown in FIG. 3A represents the distance between the framed columns near the protruding corner, and in this example, it is 2.0 m at the left protruding corner in the drawing.
[0034]
FIG. 4 is a schematic plan view of another embodiment of the present invention, showing about half of a scaffold assembled along a building and its surroundings. FIG. 3B is a cross-sectional view showing the vicinity of an inside corner of a building for assembling the scaffold of the present invention.
[0035]
This embodiment shows a case where a scaffold is constructed along the outer periphery of a building, and a corner 5 is formed in the outer periphery of the building. In addition, as an overall structure of the scaffold assembled along the outer peripheral portion of the building having the corners, the embodiment shown in FIG. 6B or FIG. 7 can be considered, for example. FIG. 4 is the same as that shown in FIG. 7, and it is determined that the lower part can be understood without showing it, so that the lower part is omitted.
[0036]
N2 shown in FIG. 3B represents a plane connecting the inner surfaces of the framed columns of the building, and this plane is a reference plane when assembling the scaffold. The horizontal length (the length of the side of the building) of the reference planes N2 and N2 sandwiching the inset part 5 shown in FIG. 4 is 3.0 m on one side and 2.0 m on the other side. The former is arranged at intervals of 2.0 m and 1.0 m, and the latter is arranged at intervals of 2.0 m. When the configuration of the corner portion 5 is enlarged, it has a structure as shown in FIG. In addition, the distance B represents the distance between the frame columns at the corners, and is 1.0 m in this example.
[0037]
The distance between the outer surface 6a of the outer wall panel and the inner surface of the tread plate 2 is configured to be 206 mm, as shown in FIG. 2 which is a side view of the scaffold. It is located at a distance of 0.2 m or 0.8 m from pillar 1. Accordingly, also in this case, joint processing of the outer wall panel and the like can be easily performed.
[0038]
Further, in this embodiment, the treadboard 21 having a length of 0.6 m and a width of 0.4 m is provided along the corner 5 in a state where the length direction thereof is oriented in the horizontal direction in the drawing. I have. Next to the tread plate 21, a tread plate 24 is provided at one end thereof, and a tread plate 22 is provided at the tip thereof, and a tread plate 23 is provided at the other end adjacent to the tread plate 21. The sum of the lengths of the treads 24 and 22 is 3.0 m, and the length of the treads 23 is 2.0 m. Accordingly, since the treads 22 and 23 protrude from the reference surfaces N1 and N2 each having a protruding corner as one end by 0.8 m, by providing the treads adjacent to the protruding portions, the interval between the treads and the reference surface can be reduced. Can be constant.
[0039]
FIG. 5 shows a side view of still another embodiment of the present invention. In this embodiment, a fall prevention fence 32 is attached to the rear step 3b shown in FIG. The length of each of the brackets 24 and 25 is, for example, 350 mm, and the distance from the reference plane N1 (N2) to the eaves is 850 mm uniformly. Therefore, the distance g between the pillar 32a of the fall prevention fence and the eaves of the roof is , 300 mm. Therefore, the work on the roof can be performed safely. Here, the distances e and f are the same values as in FIG. 2, and the distance e is 206 mm and the distance f is 800 mm.
[0040]
