Summary of the Invention

Problems to be Solved by the Invention

[0004] The temporary gantry described in Patent Document 1 has a configuration in which the base part of the tower crane is attached to a gantry constructed in the middle of the building. The mounting structure disclosed here is to be fastened with bolts or nuts from the lower side of the steel frame. However, in this configuration, workers must enter under the steel frame that serves as a scaffold, and there is a possibility of parts falling, so there is still much room for improvement in safety.

[0005] In contrast, an example of a configuration for attaching a small-scale foundation to scaffolding is shown in Patent Document 2. In this configuration, the base portion for fixing the support pole to the scaffolding is secured by screwing a lower base, which is provided at the tip of a bolt, with another bolt to embrace the beam from below and fix it to an upper base on the upper side of the scaffolding. This allows the pole to be fixed by operation only from the upper side (top surface) of the scaffolding. However, this configuration requires both a bolt with a lower base and an additional bolt, and there is a risk of mixing up parts when installing bases in multiple locations. Furthermore, it is difficult to reconfigure the system to suit the site of use or to change the specifications of the parts themselves.

[0006] In view of the above-mentioned problems, the present invention aims to provide a mounting fixture that is more versatile and easier to modify in design, and a base to which the mounting fixture can be applied. [Means for solving the problem]

[0007] The present invention, which solves the above problems, is a mounting device capable of fixing the foundation of a structure to the top surface of scaffolding, comprising a pair of pile members that can penetrate the top surface of the scaffolding, and a beam member that is detachable from the pile members and can span multiple pile members, wherein the beam member has two or more holes penetrating in a direction perpendicular to its longitudinal direction, and the pile members are provided with locking portions that can be locked into the holes. This configuration allows for a more versatile mounting fixture that is also easier to modify.

[0008] In a preferred embodiment of the present invention, the locking portion is provided spirally around the axis of the pile member and is screwable into the hole. This configuration allows the mounting fixture to be assembled or disassembled with simple operation.

[0009] In a preferred embodiment of the present invention, the holes are arranged in a line of three or more in the longitudinal direction of the beam member. This configuration allows for easy adjustment of the spacing between pile members to suit the operating conditions.

[0010] In a preferred embodiment of the present invention, the closest proximity distance between the inner surfaces of the holes corresponds to the width or height of a standardized steel material. This configuration allows for the secure attachment of the fixtures to the steel members supporting the scaffolding.

[0011] In a preferred embodiment of the present invention, the pile member has an insertion portion at one end in its axial direction through which a linear member can be inserted. This configuration makes it easy to prevent parts from falling during the installation of the mounting fixture.

[0012] In a preferred embodiment of the present invention, the pile member has a magnetic material at the end opposite to the insertion portion. With this configuration, even when the pile member and beam member are not locked together, they are attracted to each other, preventing any of the components from falling from the scaffolding.

[0013] The present invention, which solves the above-mentioned problems, is a base part to which the aforementioned mounting device can be applied. This configuration makes the method of attaching the foundation to the scaffolding more versatile and easier to modify. [Effects of the Invention]

[0014] The present invention, which solves the above problems, provides a mounting fixture that is more versatile and easier to modify in design, and a base to which the mounting fixture can be applied. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Hereinafter, the fixture X and the base part Y according to the embodiment of the present invention will be described with reference to the drawings. The description will be detailed in the order of the configuration of the embodiment, the method of implementation, and other examples. Note that the embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments.

[0017] ≪Embodiment≫ The fixture X according to the present embodiment is a set of two pile members 1 and one beam member 2, as shown in FIGS. 1(a), 1(b), and 1(c). As shown in FIG. 2, it can be connected to the base part Y in combination with a nut 3, and the base part Y can be fixed to an object. The object here is a scaffold constructed in the air, especially at a high place. This scaffold includes a platform S and a fixed beam B as shown in FIG. 3.

[0018] The pile member 1 is a member included in a plurality of sets of fixtures X. As shown in FIGS. 3, 4, and 5, it can penetrate the top surface of the scaffold (especially the platform S). The pile member 1 also has a columnar pile body 11, a locking part 12 provided around the pile body 11, an insertion part 13, and a magnet 14. In the following description, the direction of the axis A shown in FIG. 1 is taken as the axial direction, and the direction of the plane perpendicular to the axis A is taken as the cross-sectional direction.

[0019] The pile body 11 is a cylindrical member that forms the main part of the pile member 1, and a spiral locking portion 12 is provided on its side surface around the axis A. In this embodiment, the locking portion 12 is a so-called male thread formed by a spiral recess and / or protrusion, and it is preferable that it is provided over substantially the entire length of the pile body 11 in the axial direction. With this configuration, the beam member 2 can be locked at any position (height) in the axial direction of the pile body 11, and the degree of freedom in assembling the mounting fixture X is increased.

[0020] The insertion portion 13 is an annular member that protrudes from one end of the pile body 11 in the axial direction and has a through hole in any direction perpendicular to axis A, allowing a linear member to be inserted through the through hole. With this configuration, as shown in Figure 2, the auxiliary wire W can be inserted through the insertion portion 13 to assemble the mounting fixture X in a state where it can support the pile member 1, and then attach it to the foundation Y, thereby preventing parts from falling during work.

[0021] As shown in Figure 1(b), the magnet 14 is a magnetic material embedded in the end of the pile body 11 on the opposite side of the insertion portion 13 in the axial direction, and allows the beam member 2 to be attracted when the beam member 2 is made of iron or steel. This makes it possible to attract the pile member 1 and the beam member 2 even when the locking portion 12 is not used, preventing parts from falling or getting lost during transport or work.

[0022] The beam member 2 is a columnar or beam-shaped member that can be attached to and detached from the pile member 1, and enables two or more pile members 1 to be connected by spanning them. In addition, the beam member 2 has multiple holes 21 in a direction perpendicular to its length, in other words, in a direction parallel to the axis A when assembled into the mounting fixture X as shown in Figure 1(a), and the pile body 11 can pass through the holes 21.

[0023] The hole 21 is a through-hole with a cross-sectional area equal to or slightly larger than the cross-section of the pile body 11. Its inner surface is provided with a spiral recess and / or protrusion, a so-called female thread, corresponding to the locking portion 12. By screwing the locking portion 12 and the hole 21 together, the assembled state of the mounting fixture X (hereinafter referred to as the "usage state") can be maintained. With this configuration, the pile member 1 and the beam member 2 can be easily attached and detached, and the position (height) of the beam member 2 relative to the pile member 1 can be adjusted arbitrarily. Therefore, without changing the type of mounting fixture X, the usage state of the mounting fixture X can be easily obtained that matches the usage conditions (height of the fixed beam B).

[0024] The holes 21 are arranged in a series of three or more in the longitudinal direction of the beam member 2. With this configuration, when attaching two pile members 1 to one beam member 2, the spacing between the pile members 1 can be easily changed by selecting the holes 21, and the mounting fixture X can be easily used in a way that matches the usage conditions (width of the fixed beam B).

[0025] The arrangement of holes 21 in a beam member 2 is primarily such that one hole is provided near each end of the beam member 2. Other arrangements of holes 21 in the so-called intermediate section include a configuration where they are arranged at approximately equal intervals based on the two holes 21 at both ends, and a configuration where they are arranged closer to the hole 21 at one end. The example shown in the drawing is the latter, but any arrangement is acceptable as long as the distance between the two (pair) pile members 1, i.e., the distance between axes A, can be changed to two or more. With this configuration, one set of mounting fixtures X can accommodate multiple usage conditions (width of the fixed beam B), and the degree of freedom of the mounting fixtures X can be increased.

[0026] In the arrangement of the holes 21, it is preferable that the closest proximity distance between the inner circumferential surfaces (inner surfaces) of any two holes 21 is determined in accordance with the width or height of a standardized steel material. With such a configuration, when the fixed beam B is made of a general-purpose steel material, the holes 21 and the pile member 1 can be assembled to match the dimensions of the steel material, so that no unnecessary gaps are created between the fixed beam B and the pile member 1, and the foundation Y can be fixed to the scaffolding more stably.

[0027] As shown in Figure 1(a), the mounting fixture X having the above configuration is assembled to a usable state by inserting or passing through a hole 21 into a beam member 2 with two or more pile members 1 on the same side, and screwing the locking part 12 into the hole 21. With this configuration, since both the pile members 1 and beam members 2 that make up the mounting fixture X are straight-line parts, each part itself is highly versatile, and the length and cross-sectional shape can be easily changed, making it easy to modify in design and manufacturing.

[0028] The following description explains the configuration of the base Y to which this mounting bracket X can be applied.

[0029] As shown in Figure 2, the foundation Y is a structure having a plate 4 to which the attachment X can be connected and held, and a mount 5 to which the main body (main part) of the structure can be attached, and it is possible to fix and support the structure on the top surface of the scaffolding (platform S).

[0030] As shown in Figures 2, 3, 4, and 5, plate 4 is a flat plate-shaped member that allows the base Y to be placed on the top surface of the object, and has mounting holes 41 to which the mounting fixture X can be attached. The mounting holes 41 are through holes that penetrate the plate 4 in the thickness direction, and multiple holes are provided aligned across the surface direction of plate 4. The mounting holes 41 are also sized (or wide) to allow at least the pile member 1 of the mounting fixture X to pass through, so that the mounting fixture X is locked to the surface of plate 4 by fastening nuts 3 (and washers) on the vertically upper side that penetrates the mounting holes 41, and is held in a predetermined position (height).

[0031] The mounting hole 41 is preferably configured as an elongated hole having a longitudinal direction in a specific direction, as shown in Figures 2 and 3. This configuration allows for easy adjustment of the distance between the axes A of the pair of pile members 1, and enables the foundation Y to be fixed to objects of various sizes or widths.

[0032] Figures 3, 4, and 5 show the state in which the foundation Y is fixed to the platform S with the fixed beam B by the mounting fixture X (however, in Figure 3, the mount 5 is omitted for explanatory purposes). In this state, the foundation Y is placed on the top surface formed by the platform S directly above the fixed beam B, and the pile member 1 of the mounting fixture X penetrates the plate 4 and the platform S. The mounting fixture X is positioned so that the beam member 2 is tucked under the fixed beam B, and the mounting fixture X is attached so as to embrace the fixed beam B from below. A nut 3 is fastened to the pile member 1 on the upper surface of the plate 4, and (including the washer) it is locked and held in place on the surface of the plate 4. The beam member 2 abuts against the fixed beam B from below, and the fastening force of the nut 3 presses the fixed beam B vertically against the beam member 2 and the plate 4, thereby fixing the foundation Y to the top surface of the platform S.

[0033] In the example of the present invention shown in Figure 4, the fixed beam B is an H-shaped steel member, while in Figure 5, the fixed beam B is a channel steel member with a U-shaped cross-section. In both cases, the width in the horizontal direction, i.e., the plane direction of the platform S, is different. However, by changing the distance between the axes A of the pair of pile members 1 attached to the beam member 2, and the distance between the axes A of the pile members 1 that pass through the mounting holes 41, the mounting fixture X can be attached to match the size of the cross-section of the fixed beam B, and the foundation Y can be made to accommodate various mounting conditions.

[0034] Figure 6 shows an example of the use of the mounting bracket X and base Y according to this embodiment. In this example, a crane boom P for a simple crane is attached to the base Y, which is fixed to the platform S and the fixed beam B. In this way, the mounting bracket X and base Y can be used when fixing a temporary structure to the top surface of the scaffolding (on the platform S).

[0035] The following describes in detail the method of carrying out the present invention with reference to the drawings. Furthermore, the method of carrying out the invention described below is merely an example, and is not limited to this method; the order of the steps may also be changed.

[0036] ≪Implementation Method≫ The user first places the base Y on the top surface of the platform S. At this time, it is preferable that the position of the base Y be approximately directly above the fixed beam B, and that the longitudinal direction of the mounting holes 41 of the plate 4 intersects with the longitudinal direction of the fixed beam B. This makes it easy to change the fixing position of the mounting fixture X.

[0037] Next, the user pre-inserts the washer and nut 3 onto the second pile member 1, and then screws the beam member 2 onto the tip of the first pile member 1 on the magnet 14 side. The user then inserts the beam member 2 through the mounting hole 41 and the gap in the mesh of the platform S, passing it partway through the connected pile member 1. At this time, inserting the auxiliary wire W into the insertion part 13 beforehand prevents the pile member 1 and beam member 2 from falling. After that, the user similarly passes the remaining pile member 1 (and washer and nut 3) through the mounting hole 41 and the gap in the mesh of the platform S.

[0038] Next, the user determines the hole 21 for connecting the unconnected pile member 1 and beam member 2, according to the width of the fixed beam B, and screws the second pile member 1 into the beam member 2. After that, the user tightens the nut 3 to hold the fixed beam B in place with the mounting bracket X and plate 4, and attaches the foundation Y.

[0039] The user performs the above work using one or two sets (or more) of the mounting brackets X, securing the base Y so that it does not shift from the platform S (the top surface of the scaffolding). By performing the above work method, the user can perform all work on the platform S, thereby improving safety.

[0040] Furthermore, the user then attaches the structure to the mount 5 on the base Y, as shown in Figure 6. The example shown in Figure 6 is a configuration in which a crane boom P, whose direction can be changed, is attached to the pivot axis provided on the mount 5, creating a simple crane. In addition, it is also possible to attach the legs of temporary equipment to the mount 5 to perform work at height (on scaffolding) safely and at low cost.

[0041] When the user removes the mounting bracket X and base Y, they should detach the mounting bracket X and base Y from the fixing beam B and platform S by following the reverse procedure described above.

[0042] An example of applying the aforementioned implementation method is a method for installing enclosure-shaped equipment against a wall. In this example, when it is necessary to fix enclosure-shaped equipment to a wall, the entire mounting bracket X is used horizontally for low-strength walls (such as foamed concrete walls or block walls) where ordinary anchor bolts do not function. In this configuration, the pile member 1 penetrates the wall, the beam member 2 holds the enclosure so as to press it against the wall, and the pile member 1 is fixed to the wall with a nut 3 or the like on the opposite side of the wall, thereby fixing the enclosure against the wall. This configuration increases the options for the installation location of equipment to be installed on a wall. [Explanation of Symbols]
