Description

Technical Field

[0001] The present invention relates to an attachment support device for attaching and fixing a wall connecting member that connects a temporary scaffold to an outer wall of a building.

Background Art

[0002] A temporary scaffold including columns erected at predetermined intervals along the outer wall of a building is connected to the columns and the outer wall by a wall connecting member.

[0003] Generally, the wall connecting member is configured to connect the outer wall of the building from the columns of the temporary scaffold, includes a rod extending perpendicular to the wall surface from the clamp fitting to the outer wall, and has a bolt portion provided at the tip of the rod. Therefore, the clamp fitting is fastened to the column, and the bolt portion is screwed onto a nut member fixed to the outer wall, thereby connecting the column and the outer wall.

[0004] However, in this case, it is necessary that the column of the constructed temporary scaffold and the nut member fixed to the outer wall of the building face each other in a facing position. In other words, when the column and the nut member are not in a facing position, the rod of the wall connecting member is attached in an inclined posture that is not perpendicular to the outer wall, so a predetermined bearing capacity cannot be ensured.

[0005] That is, since the attachment and fixing position of the clamp fitting of the wall connecting member is limited to the position of the column, there is a possibility of causing the above-mentioned problems when connecting to the nut member fixed to the outer wall.

[0006] Therefore, a support device has been proposed that is configured so that the attachment and fixing position of the clamp fitting of the wall connecting member is not limited to the position of the column and can be attached and fixed at a free range of positions (Patent Document 1 and Patent Document 2).

[0007] The support device has a shaft member that extends between the two support columns, with both ends of the shaft member being detachably fixed to the adjacent support columns. Therefore, it has the advantage that a wall tie can be attached and fixed at a selected desired position on the shaft member that extends in the axial direction. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2016-56639 [Patent Document 2] Utility Model Registration No. 3211768 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0009] However, the support device lacks sufficient load-bearing capacity because the means for fixing and supporting the clamp fittings of the wall tie material consists only of a single shaft member extending between a pair of support columns. For example, when the temporary scaffolding swings toward or away from the outer wall, the shaft member, with both ends fixed to the support columns, is subjected to bending stress in the middle section by the wall tie material, and is therefore prone to deformation.

[0010] Therefore, a reinforcing structure is necessary to ensure sufficient strength of the shaft members, but there are various unresolved issues regarding what kind of structure should be used for reinforcement.

[0011] In view of the above, the present invention aims to propose a mounting support device that provides flexibility in the mounting and fixing position of wall tie materials, possesses high strength, and is also easy to use. [Means for solving the problem]

[0012] Therefore, the means configured by the present invention relates to a temporary scaffolding constructed including support columns erected at predetermined intervals along the outer wall of a building, and in a configuration in which wall ties are provided to connect the temporary scaffolding to the outer wall, the present invention provides a mounting support device for attaching and fixing the clamp fittings of the wall ties to the temporary scaffolding, the mounting support device is composed of a main shaft member extending between two support columns with both ends detachably fixed to adjacent support columns, a secondary shaft member extending substantially parallel to the main shaft member, and a connecting reinforcing member that connects the main shaft member and the secondary shaft member with a gap between them, and is configured such that the clamp fittings of the wall ties are tightly fastened to the outer surface of the main shaft member through the gap.

[0013] In a preferred embodiment, the main shaft member and the sub-shaft member are integrally connected at their end faces by end connecting reinforcing members positioned at both ends in the axial direction, and the intermediate portions of both shaft members are connected by intermediate connecting reinforcing members positioned at predetermined intervals in the axial direction. The shaft portion of the main shaft member between adjacent connecting reinforcing members forms a mounting portion that allows the clamp fitting to be fastened, and fastening fittings are provided on the end connecting reinforcing members, and these fastening fittings are configured to be detachably fixed to the support column.

[0014] Preferably, the main shaft member is configured to have a right shaft portion and a left shaft portion centered on the midpoint of the axis connecting both ends, and is configured so that the fastening fittings can be detachably fixed to a pair of adjacent support columns in a temporary scaffold even when it is inverted around the midpoint, and the arrangement of the intermediate connecting reinforcing members is configured to be asymmetrical with respect to the midpoint between the arrangement of the right shaft portion and the arrangement of the left shaft portion.

[0015] More preferably, the main shaft member is positioned near the support column of the temporary scaffolding and the outer wall of the building, and the secondary shaft member is positioned on the outer wall side of the main shaft member, forming the gap. With the fastening fitting fixed to the support column, the end connecting reinforcing member is configured to position the secondary shaft member vertically offset with respect to a horizontal line crossing the main shaft member. [Effects of the Invention]

[0016] According to the present invention, when connecting temporary scaffolding to the exterior wall of a building with wall ties, the mounting and fixing position for fastening the clamp fittings 7 of the wall ties 6 is not limited to the position of the support columns of the temporary scaffolding. The main shaft member 12 of the mounting support device 11 allows for mounting and fixing at any position within a range selectable in the axial direction. Furthermore, by connecting the sub-shaft members 13, which extend almost parallel to the main shaft member 12, with connecting reinforcing members while forming gaps S between them, a rigid frame structure is formed, which has the effect of maintaining excellent strength.

Mode for Carrying Out the Invention

[0018] The preferred embodiments of the present invention will be described in detail below based on the drawings. FIGS. 1 to 5 show the basic embodiment of the mounting support device, and FIG. 6 shows another embodiment.

[0019] As shown in FIG. 1, the temporary scaffold 1 is constructed including columns 2 erected at predetermined intervals along the outer wall W of the building. In the illustrated example, a work floor is formed by mounting a scaffold board 4 on a cross member 3 provided on the column 2, and a single-pipe scaffold with a front handrail 5 straddling between adjacent columns 2, 2 is shown, but it is not limited thereto, and a framework scaffold may also be used.

[0020] Therefore, the temporary scaffold 1 is connected to the outer wall W by a wall connecting member 6. A conventionally known wall connecting member 6 can be used, and it includes a rod 8 extending in a direction perpendicular to the outer wall W from a clamp fitting 7, and a bolt portion 9 is provided at the tip of the rod 8.

[0021] As shown in FIG. 4, the clamp fitting 7 pivotally connects a rotating jaw portion 7b to a fixed jaw portion 7a attached to the rod 8, and in a state where the outer peripheral surface of a predetermined pipe member in the temporary scaffold 1 is held by both jaw portions 7a, 7b, it is configured to be fastened by fastening means 7c composed of a bolt and a nut.

[0022] Thereby, as shown in the drawing, the clamp fitting 7 is fastened to a predetermined pipe member of the temporary scaffold 1, and the bolt portion 9 is screwed onto a nut member 10 fixed to the outer wall W, so that the temporary scaffold 1 and the outer wall W are configured to be connected.

[0023] Incidentally, the building's exterior wall W used to connect the temporary scaffolding 1 does not need to be interpreted as being limited to an exterior wall in the strict sense; in short, any part of the building's exterior that can connect and hold the temporary scaffolding 1 using wall ties 6 is acceptable.

[0024] A mounting support device 11 is used to provide a pipe material for attaching and fixing the clamp fittings 7 of the wall tie material 6 to the temporary scaffolding 1.

[0025] (Basic implementation) As shown in Figures 1 to 3, the mounting support device 11 consists of a main shaft member 12 extending between adjacent support columns 2, 2 with both ends detachably fixed to the columns, a secondary shaft member 13 extending substantially parallel to the main shaft member, and a connecting reinforcing member 14 that connects the main shaft member 12 and the secondary shaft member 13 with a gap S between them.

[0026] The main shaft member 12 is made of a metal pipe having an outer diameter that allows the clamp fitting 7 of the wall tie member 6 to be fastened to it, and the secondary shaft member 13 is made of a metal pipe having a smaller outer diameter than the main shaft member 12.

[0027] The connecting reinforcing member 14 consists of a bracket-shaped end connecting reinforcing member 14a made of metal plates that are arranged at both ends of the main shaft member 12 and the sub-shaft member 13, and a bridge-shaped intermediate connecting reinforcing member 14b made of metal plates that are located in the middle of both shaft members 12 and 13 and are arranged at a predetermined interval in the axial direction.

[0028] The bracket-shaped end connecting reinforcing member 14a is fixed by welding in contact with the shaft end faces of the main shaft member 12 and the sub-shaft member 13, and is reinforced by welding an L-shaped metal reinforcing plate 15 to its outer surface to integrate it, with a fastening fitting 16 provided on the bent piece 15a of the reinforcing plate 15.

[0029] The fastening fitting 16 constitutes a means for detachably fixing both ends of the mounting support device 11 to the support column 2. In the illustrated embodiment, a rotating jaw portion 18 is pivotally connected to a fixed jaw portion 17, and the outer circumferential surface of the support column 2 is held by both jaw portions 17 and 18, and the fastening fitting is configured as a clamping means that fastens with a fastening means 19 consisting of bolts and nuts. Therefore, the fastening fitting 16 can be fixed to any point in the axial direction of the support column 2, thereby making it possible to install the main shaft member 12 at a desired height position.

[0030] In the embodiments shown in Figures 1 to 5, the mounting support device 11 is configured such that when the fastening fitting 16 is fixed to the support column 2, the main shaft member 12 is positioned near the support column 1, and the secondary shaft member 12 is positioned on the side facing the outer wall W from the main shaft member 12, with the gap S between them.

[0031] As shown in Figure 3(B), the bracket-shaped end connecting reinforcement member 14a is fixed to the support column 2 erected along the vertical line V using a fastening fitting 16, and the sub-axis member 13 is positioned offset upward or downward (upward in the illustrated case) at an angle θ with respect to the horizontal line H that crosses the center of the main axis member 12. This creates a passage 20 along the horizontal line H, and the passage 20 is formed below the sub-axis member 13 so as not to interfere with the sub-axis member 13, and as will be described later, enables the horizontal installation of the wall tie member 6.

[0032] The bridge-shaped intermediate connecting reinforcement member 14b is provided across the gap S and is fixed to the main shaft member 12 and the sub-shaft member 13 by welding. As a result, the mounting support device 11 forms a rigid frame structure with the parallel-arranged main shaft member 12 and sub-shaft member 13, the bracket-shaped end connecting reinforcement member 14a that connects and integrates them, and the bridge-shaped intermediate connecting reinforcement member 14b.

[0033] The mounting support device 11, configured as described above, is fixed to the support columns 2 at both ends by fastening fittings 16, and provides mounting portions 21 for attaching and fixing the clamp fittings 7 of the wall tie material 6 by the main shaft member 12 extending between the pair of support columns 2, 2. Specifically, in the regions near both ends in the axial direction, the mounting portion 21 is formed by the outer circumference of the main shaft member 12 extending between the end connecting reinforcing member 14a and the intermediate connecting reinforcing member 14b, and in the intermediate region, the mounting portion 21 is formed by the outer circumference of the main shaft member 12 extending between the adjacent pair of intermediate connecting reinforcing members 14b, 14b. Therefore, it is possible to attach and fix the clamp fittings 7 of the wall tie material 6 by fastening them to a selected mounting portion 21.

[0034] In this case, the height position of the main shaft member 12, which determines the vertical mounting position of the wall tie member 6, is determined by adjusting the fixing position of the fastening fitting 16 in the axial direction of the support column 2 when attaching the mounting support device 11 to the support column 2. In other words, as described above, by adjusting the fixing position of the fastening fitting 16 in the vertical direction, the main shaft member 12 is fixed at the same height position as the nut member 10 of the outer wall W.

[0035] Therefore, after fixing the mounting support device 11 to the support column 2, a mounting portion 21 is selected that is directly opposite the nut member 10 of the outer wall W in the axial direction of the main shaft member 12, and the clamp fitting 7 of the wall tie member 6 is fastened to a predetermined position in the axial direction of the mounting portion 21, and the bolt portion 9 is screwed into the nut member 10, thereby fixing the rod 8 to the outer wall W in a position perpendicular to the outer wall W, and thereby the temporary scaffolding 1 can be connected to the outer wall W of the building via the mounting support device 11.

[0036] As described above, since the mounting support device 11 positions the main shaft member 12 near the support column 1, the distance between the main shaft member 12 and the outer wall is not significantly different from the distance between the support column 1 and the outer wall. For this reason, conventional wall ties (provided between the support column and the nut member of the outer wall) can be used, and any slight difference in distance can be absorbed by adjusting the bolt portion 9 and the nut member 10.

[0037] Furthermore, the wall tie member 6 is positioned horizontally in the vertical direction and perpendicular to the outer wall W in the horizontal direction (the axial direction of the main shaft member 12), thereby being installed perpendicular to the wall surface of the outer wall W.

[0038] In this state, when the temporary scaffolding 1 swings toward or away from the outer wall W, the main shaft member 12, with both ends fixed to the support column 2 of the temporary scaffolding 1 by fastening fittings 16, receives an external force from the wall tie member 6 in a reciprocating direction along the horizontal line H at the intermediate attachment part 21, thereby generating bending stress. However, the main shaft member 12 is constructed by arranging a secondary shaft member 13 that extends almost parallel to it, and connecting and integrating both shaft members 12 and 13 with connecting reinforcing members 14a and 14b. Since the load-bearing capacity of the main shaft member 12 is supplemented and strengthened by the secondary shaft member 13, it does not easily deform and bend.

[0039] In particular, in the illustrated embodiment, the main shaft member 12 and the sub-shaft member 13 are connected by a bridge-shaped intermediate connecting reinforcing member 14b at a predetermined interval in the axial direction. Therefore, the mounting portion 21 that receives the external force is formed as a rigid structure with a rectangular frame formed by a pair of connecting reinforcing members 14b, 14b and the shaft portions of the main shaft member 12 and sub-shaft member 13 extending between them, and is formed in a strip shape in the axial direction of the main shaft member 12, so there is no risk of deformation.

[0040] Figure 4 shows how to fasten the clamp fitting 7 of the wall tie material 6 to the mounting portion 21.

[0041] As shown in Figure 4(A), the clamp fitting 7 of the wall tie material 6 is positioned with the fixed jaw portion 7a attached to the rod 8 and the rotating jaw portion 7b open, and one jaw portion is inserted into the gap S between the main shaft member 12 and the sub-shaft member 13, so that the fixed jaw portion 7a faces the outer surface of the mounting portion 21.

[0042] As described above, a passage 20 is formed on the lower side of the sub-shaft member 13, which includes a horizontal line H perpendicular to the outer wall W from the center of the main shaft member 12. Therefore, as shown in Figure 4(B), the fixed jaw portion 7a and the rotating jaw portion 7b can be closed with the rod 8 positioned along the horizontal line H.

[0043] In this state, when the fastening means 7c is fastened, the fixed jaw portion 7a and the rotating jaw portion 7b sandwich the outer peripheral surface of the mounting portion 21, so that the clamp fitting 7 is fastened to the mounting portion 21 of the spindle member 12 via the gap S.

[0044] By the way, since the mounting support device 11 forms a rigid frame of a rigid structure, the spindle member 12 forms the mounting portion 21 only at a location where the intermediate portion connecting and reinforcing member 14b is not provided in the axial direction. In other words, at a location where the intermediate portion connecting and reinforcing member 14b is provided, the clamp fitting 7 of the wall connecting member 6 cannot be fastened. For this reason, when the intermediate portion connecting and reinforcing member 14b is in the facing position with respect to the nut member 10 of the outer wall W, a situation will occur in which the wall connecting member 6 cannot be attached and fixed to the outer wall W in a perpendicular posture.

[0045] In order to solve the problem in this regard, as shown in Fig. 5(A), the mounting support device 11 is configured with a right-side shaft portion 11R and a left-side shaft portion 11L centered on the midpoint C of the axis connecting both ends of the spindle member 12. Moreover, as shown in Fig. 5(B), with respect to a pair of adjacent columns 2, 2 of the temporary scaffold 1, the fastening brackets 16, 16 can be detachably fixed to the columns 2, 2 even when inverted about the midpoint C.

[0046] Regarding the arrangement form of the intermediate portion connecting and reinforcing member 14b, the arrangement form in the right-side shaft portion 11R and the arrangement form in the left-side shaft portion 11L are configured to be asymmetric with respect to the midpoint C. In the case of the illustrated embodiment shown in Fig. 5(A), the respective distances R1, R2, R3 of the three intermediate portion connecting and reinforcing members 14b arranged in order from the midpoint C in the right-side shaft portion 11R, and the respective distances L1, L2, L3 of the three intermediate portion connecting and reinforcing members 14b arranged in order from the midpoint C in the left-side shaft portion 11L are configured such that R1 < L1, R2 < L2, and R3 < L3.

[0047] As a result, the mounting support device 11 is configured such that the clamp fittings 7 of the wall tie material 6 can be fastened to any point along the entire length of the main shaft material 12 by selecting between two mounting positions: P1, in which the right-side fastening fitting 16R is fixed to the right-side support column 2R and the left-side fastening fitting 16L is fixed to the left-side support column 2L, as shown in Figure 5(A); and P2, in which the left-side fastening fitting 16L is fixed to the right-side support column 2R and the right-side fastening fitting 16R is fixed to the left-side support column 2L, as shown in Figure 5(B).

[0048] In other words, with respect to the axial direction of the main shaft member 12, when the mounting position P1 shown in Figure 5(A) is adopted, the position or location where the intermediate connecting reinforcing member 14b is provided becomes a non-fastening section where the clamp fitting 7 cannot be fastened. However, in this case, if the mounting position P2 shown in Figure 5(B) is adopted, the mounting portion 21 faces the position that was previously the non-fastening section, thereby making it possible to fasten the clamp fitting 7. As a result, it becomes possible to fasten the clamp fitting 7 at any point along the entire length of the main shaft member 12, and the wall tie member 6 can always be connected to the nut member 10 in a perpendicular position to the outer wall W.

[0049] Furthermore, as shown in Figure 6, the mounting support device 11 can also be used in a reversed state with respect to the outer wall direction.

[0050] In the case of Figure 6(A), as described above, the mounting support device 11 is installed in an outward orientation P3 with the main shaft member 12 facing the outer wall W from the vicinity of the support column 1. In this case, the mounting support device 11 narrows the gap D between the temporary scaffolding 1 and the outer wall W, but does not interfere with the working space above the scaffolding board 4 supported by the support column 2, and therefore does not obstruct the movement of workers.

[0051] In contrast, as shown in Figure 6(B), the mounting support device 11 is installed in an inward-facing position P4, with the main shaft member 12 facing the workspace above the scaffolding board 4 from the vicinity of the support column 1 by reversing its orientation with respect to the outer wall. In this case, the mounting support device 11 interferes with the workspace above the scaffolding board 4 supported by the support column 2, but it does not narrow the gap D between the temporary scaffolding 1 and the outer wall W. Therefore, by using the gap D as a passageway, this inward-facing position P4 is advantageous when lifting or lowering materials such as ALC panels or other components.

[0052] (Another embodiment) Figure 7 shows another embodiment of the mounting support device 11, which consists of a main shaft member 12 extending between two adjacent support columns 2, 2 with both ends detachably fixed to the columns, a secondary shaft member 13 extending substantially parallel to the main shaft member, and a connecting reinforcing member 14 that connects the main shaft member 12 and the secondary shaft member 13 with a gap S between them. The connecting reinforcing member 14 consists of bracket-shaped end connecting reinforcing members 14a positioned at both ends of the main shaft member 12 and the secondary shaft member 13, and a bridge-shaped intermediate connecting reinforcing member 14b positioned in the middle of both shaft members 12 and 13 and positioned at a predetermined interval in the axial direction, with fastening fittings 16 provided on the end connecting reinforcing member 14a. Furthermore, a mounting portion 21 is formed by the outer circumference of the main shaft member 12 extending between the end connecting reinforcing member 14a and the intermediate connecting reinforcing member 14b, and a mounting portion 21 is formed by the outer circumference of the main shaft member 12 extending between a pair of adjacent intermediate connecting reinforcing members 14b, 14b. These configurations are the same as in the above embodiment.

[0053] To explain the differences from the above embodiment, the mounting support device 11 is configured such that when the fastening fitting 16 is fixed to the support column 2, the sub-shaft member 13 is positioned near the support column 1, and the main shaft member 12 is positioned with a gap S between it and the outer wall W, away from the sub-shaft member 13. The main shaft member 12 and the sub-shaft member 13 are positioned on the horizontal line H. Therefore, even without offsetting by an angle θ (Figure 3(B)) as in the above embodiment, when fastening the clamp fitting 7 of the wall tie member 6 to the mounting portion 21 of the main shaft member 12 with a gap S, the side of the main shaft member 12 facing the outer wall W is an open space, making the work easy to perform.

[0054] Furthermore, the main shaft member 12, the sub-shaft member 13, and the intermediate connecting reinforcing member 14b are aligned along the axis (horizontal line H) of the rod 8 of the wall tie member 6 to form a frame structure. Thus, the sub-shaft member 13 and the intermediate connecting reinforcing member 14b provide a rigid structure that suitably reinforces the main shaft member 12 against horizontal external forces acting from the wall tie member 6 to the mounting portion 21.
