Description

[Technical field]

[0001] The present invention relates to a construction support device and a method for lifting and transporting materials and equipment using the construction support device. [Background technology]

[0002] For example, when replacing the deck of a road bridge, superstructure widening work may be carried out at the same time to widen the superstructure using the median strip opening to add a lane. Superstructure widening work involves merging the median strip by closing the median strip opening.

[0003] The work of merging medians involves, for example, cutting and removing the wall parapets adjacent to the median strip openings on the up and down lanes, adding girders, and installing a new deck on the added girders. All of these processes require equipment such as lifting devices such as large cranes to lift materials and equipment to and from the ground, and transport carts to transport the lifted materials and equipment. For this reason, on road bridges, construction restrictions are often implemented to reduce the number of lanes, not only to ensure work zones but also to secure space to deploy such equipment.

[0004] However, construction work involving lane restrictions is likely to cause traffic congestion, which may affect the surrounding living environment and economic activity, and there is also concern that it may lead to accidents, so it is desirable to carry out superstructure widening work without traffic restrictions or with small-scale construction restrictions that reduce the number of lanes. Therefore, a method using a bridge crane, as described in Patent Document 1, is being considered.

[0005] The bridge crane in Patent Document 1 has an upper beam and legs attached to both ends, the upper beam is provided with a suspension mechanism equipped with a hoist for suspending an object to be transported, and the legs are provided with wheel units that move on a pair of rails laid on the ground.

[0006] To use a bridge crane with this configuration in superstructure widening work, first, a pair of rails are laid on the road surface on both the up-bound and down-bound lanes, with the median strip in between. Next, the bridge crane is installed on the pair of rails, straddling the median strip opening. This allows materials and equipment to be hoisted from the ground using the median strip opening, and then moved along the rails while hoisting the materials and equipment, to be transported to any desired destination on the road bridge.

[0007] [Patent Document 1] JP 2018-177403 A Summary of the Invention [Problem to be solved by the invention]

[0008] As mentioned above, by installing a bridge crane, the space above the median strip can be utilized, making it possible to lift and transport materials and equipment without restricting traffic or contributing to the minimization of lane restrictions.However, the road surface on which the rails are laid generally has a slope in the direction of the bridge axis, and depending on the construction site, the allowable limit for the rail slope (1 / 500) set out in the crane installation guidelines may be exceeded.

[0009] Similarly, if there is a difference in level between the up line and the down line, the horizontal difference between the left and right rails may exceed the allowable limit (1 / 500). In an environment like this where it is difficult to meet the installation guidelines, it is not possible to use a bridge crane to lift and transport materials and equipment.

[0010] The present invention has been developed in consideration of such problems, and its main purpose is to ensure that a construction support device can function as a crane regardless of the condition of the installation surface on which the construction support device is installed, and to support on-site work related to lifting and transportation. [Means for solving the problem]

[0011] In order to achieve this objective, the construction support device of the present invention comprises a frame having a plurality of column members, beam members and girder members, a lifting mechanism supported by the frame, and a support mechanism supporting the frame, wherein the column members include an extension mechanism for adjusting the length of the column members, the support mechanism includes a running means and an outrigger, and the lifting mechanism includes a girder arranged parallel to the beam members and movable along the girder members, a trolley that moves along the girder, a hoisting device supported by the trolley, and a lifting device suspended from the hoisting device via a wire.

[0012] The construction support device of the present invention is characterized in that a load receiving means is provided on the pillar member.

[0013] The construction support device of the present invention is characterized in that the pillar member includes a pillar body, the telescopic mechanism is coaxially provided at the lower end of the pillar body, and the load receiving means is provided above the telescopic mechanism.

[0014] The method for lifting and transporting equipment and materials of the present invention is a method for lifting and transporting equipment and materials using the construction support device of the present invention, and is characterized in that it includes a moving process of moving the construction support device to the vicinity of a lifting position for the equipment and materials, a building formation process of extending the outriggers to install the construction support device near the lifting position and forming the frame supported by the support mechanism into a building, and an overhead crane formation process of using the extension mechanism to adjust the beam members and the girder members to be approximately horizontal and forming the lifting mechanism into an overhead crane installed in the building.

[0015] The method for lifting and transporting equipment and materials of the present invention is characterized by comprising a loading process in which the equipment and materials are hoisted down and supported by the load receiving means, and a transport cart formation process in which the outriggers are retracted to ground the running means and the construction support device is used as a transport cart.

[0016] The method for lifting and transporting equipment and materials of the present invention is characterized in that a floor joist extending parallel to the beam member is installed so as to span the adjacent load receiving means, and during the loading process, the equipment and materials are supported on the load receiving means via the floor joist.

[0017] The method for lifting and transporting equipment and materials of the present invention is characterized in that the lifting position for the equipment and materials is an opening in a median strip of a road bridge.

[0018] According to the construction support device and the method for lifting and transporting materials and equipment of the present invention, the pillar members of the frame include an extension mechanism, and the support mechanism includes a traveling means and an outrigger. As a result, when the installation surface of the construction support device is inclined, the frame can be supported by the outriggers and treated as a "building," and the extension mechanism provided on the pillar members can be used to make the girder members and beam members approximately horizontal, making it possible to treat the lifting mechanism as an overhead crane that satisfies the installation guidelines provided for the "building."

[0019] Therefore, regardless of whether the construction site is sloped, uneven, or has steps, the construction support device can be ensured to function as a crane, making it possible to support on-site work related to lifting and transportation.

[0020] Furthermore, by providing a load receiving means on the pillar member, the construction support device can function as a transport cart that transports the load on the load receiving means to a distant destination when the lifting mechanism is not in use. This makes it possible to perform a series of operations from lifting materials and equipment to long-distance transport using only the construction support device, thereby further improving the efficiency of on-site work.

[0021] Therefore, for example, if it is desired to use the median opening of a road bridge that has a gradient in the bridge axis direction and a step in the direction perpendicular to the bridge axis to hoist materials and equipment, the construction support device is placed across the median opening, the frame is supported by the outriggers, and the beam and girder members are made approximately horizontal by utilizing the telescopic mechanism of the column members. In this way, the lifting mechanism can be treated as an overhead crane installed in a building made of a frame, and materials and equipment can be hoisted from the ground to above the road bridge using the median opening, and the suspended materials and equipment can be transported horizontally within the frame.

[0022] Furthermore, by lowering the suspended materials and equipment onto the load receiving means and supporting the frame on the traveling means, the construction support device can function as a transport cart that straddles the median strip, and the space above the median strip can be used to transport materials and equipment over long distances. In this way, the median strip can be effectively utilized, making it possible to carry out lifting and transporting work on materials and equipment without traffic restrictions or with only minor construction restrictions in various road bridge construction works, which can contribute to preventing traffic congestion and accidents. Effect of the Invention

[0023] According to the present invention, by including an extension mechanism in the column members of the frame and including a running means and outriggers in the support mechanism, the construction support device can function as a crane regardless of the condition of the installation surface, making it possible to support on-site work related to lifting and transportation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The present invention provides a construction support device with both a crane function and a transport vehicle function, regardless of the condition of the installation surface on which the construction support device is installed, and supports on-site work such as lifting and transporting long or heavy materials and equipment, and long-distance transport. The construction support device and the method for transporting materials using the construction support device will be described in detail below, taking a long girder block as an example of the materials and equipment, with reference to Figs. 1 to 10.

[0026] ≪≪Construction support equipment≫≫ As shown in the cross-sectional view of Figure 1 (cross-section AA in Figure 3), the side view of Figure 2, and the plan view of Figure 3, the construction support device 100 comprises a frame 10, a support mechanism 20 that supports the frame 10, a lifting mechanism 30 provided on the frame 10, and a load receiving means 40 provided on the frame 10.

[0027] <Frame> As shown in Figures 1 and 2, the frame 10 comprises a pair of girder members 11, beam members 12 arranged to connect the girder members 11, and a number of column members 13 each supporting the girder members 11, and is formed in a gate shape when viewed from the front.

[0028] Both the girder member 11 and the beam member 12 are made of long steel materials, and an example is given of a case in which H-shaped steel is used. On the other hand, the column member 13 is made of a column main body 131 and an extension mechanism 132.

[0029] The column body 131 is made of a long steel material, and in Fig. 1, a square steel pipe is used as an example. The extension mechanism 132 is disposed coaxially with the column body 131 at the lower end of the column body 131, and for example, a hydraulic jack can be used.

[0030] As a result, the column member 13 can be expanded or contracted in length by expanding or contracting the expansion mechanism 132. Therefore, even if the installation surface of the construction support device 100 is inclined, uneven, or has a step, the girder member 11 and the beam member 12 can be adjusted to be approximately horizontal by using the expansion mechanism 132.

[0031] The telescopic mechanism 132 may be disposed not only on the lower end side of the column body 131 but also on the upper end side, or may be disposed so as to be sandwiched between the upper and lower parts of the column body 131. Alternatively, the column body 131 may have a structure in which the telescopic mechanism 132 is built in, for example, by making the column body 131 into a telescopic structure.

[0032] In the frame 10 having such a configuration, as shown in Fig. 2, three column members 13 support one girder member 11, and as shown in Fig. 3, one beam member 12 connects a pair of girder members 11. However, the number of the columns is not limited in any way.

[0033] ≪Support mechanism≫ The support mechanism 20 is a mechanism for supporting the frame 10, and includes a support base 21, a traveling means 22, and an outrigger 23, as shown in FIG.

[0034] The support stand 21 is composed of, for example, a cross member 211 and a traveling means storage section 212 having a U-shaped cross section. The traveling means storage section 212 is made of a long steel material having a U-shaped cross section, and is arranged so as to extend in a direction parallel to the girder member 11 as shown in Fig. 2. The cross member 211 is a flat steel plate installed on the upper surface of the traveling means storage section 212, and is provided so as to protrude in the extension direction of the beam member 12.

[0035] 2, the cross members 211 are arranged at the same intervals as the multiple pillar members 13 arranged at intervals in a direction parallel to the girder member 11, and the pillar members 13 are installed on the upper surfaces of the cross members 211. As a result, the multiple pillar members 13 are connected at their lower ends by the support frame 21. Then, as shown in FIG. 1, outriggers 23 are installed on the underside of the area of ​​the cross member 211 that protrudes from the traveling means storage section 212, and the traveling means 22 is provided inside the traveling means storage section 212.

[0036] The traveling means 22 is a wheel with an axle supported on the vertical wall of the traveling means storage section 212, and travels on a guide rail 50 laid on the road. However, the traveling means 22 is not limited to this, and tires or crawlers that do not require the guide rail 50 may be used.

[0037] The outriggers 23 may be any type of extension device, such as a hydraulic jack, so long as they are capable of extending and contracting to the extent that they do not impede the travel of the traveling means 22 when contracted, prevent the traveling means 22 from traveling when extended, and can support the frame 10.

[0038] ≪Lifting mechanism≫ 1, the lifting mechanism 30 is a device supported by the frame 10 and capable of lifting the girder block G and transporting the girder block G in the girder direction and beam direction within the frame 10. The lifting mechanism 30 may have any configuration, but may include, for example, a girder 31, a trolley 32, a hoisting device 33, a wire 34, a hoisting tool 35, and a saddle 36.

[0039] As shown in Fig. 3, the girders 31 extend in a pair parallel to the beam members 12, and both ends are supported by saddles 36. The saddles 36 are provided with guide rollers (not shown), and are supported by each of the pair of girder members 11 and move along the pair of girder members 11. The saddles 36 are slide tables that move along running rails 111 provided on the girder members 11, as shown in Fig. 2.

[0040] As shown in Fig. 3, the trolley 32 is installed so as to straddle a pair of girders 31, moves along the girders 31, and supports a hoisting device 33. The trolley 32 is a traverse vehicle that moves along a crab rail 311 provided on the girder 31. The hoisting device 33 is a device that winds up or unwinds a wire 34 as shown in Figs. 1 and 2, and a hoisting tool 35 is attached to this wire 34.

[0041] As a result, the lifting mechanism 30 can freely move the girder block G suspended by the hoisting device 35 within the frame 10 in a direction parallel to the girder members 11 and in a direction parallel to the beam members 12. Furthermore, when the frame 10 is supported by the outriggers 23 and can be handled as a "building", and when the girder members 11 and the beam members 12 are maintained approximately horizontally, the lifting mechanism 30 can be handled as a "ceiling crane" installed in the "building" consisting of the frame 10.

[0042] The procedure for using the lifting mechanism 30 as an "overhead crane" will be described later in "<<Method for transporting girder block G using the construction support device 100>>". In this embodiment, as shown in Fig. 2, two lifting mechanisms 30 are provided on the frame 10, but any number of lifting mechanisms may be provided.

[0043] <Means of receiving goods> 1 and 2, the load-receiving means 40 is a stand capable of loading a girder block G via a joist 60, and is provided on each column member 13. Its height position may be any position above the telescopic mechanism 132. For example, it is disposed so as to be sandwiched between the column main body 131 and the telescopic mechanism 132, and is provided so as to protrude in a direction perpendicular to the axis of the column main body 131.

[0044] Such a load receiving means 40 may be selectively provided on any of the multiple column members 13. The protruding direction may also be any direction as long as it is perpendicular to the axis of the column main body 131. For example, adjacent load receiving means 40 may be connected in the extending direction of the girder member 11. Furthermore, the load receiving means 40 may be installed so as to be able to freely protrude and retract into the frame 10, or the joist material 60 may be omitted so that the girder blocks G can be directly loaded.

[0045] The load receiving means 40 configured as described above is a jig used when the frame 10 is supported by the traveling means 22 without using the lifting mechanism 30, and the construction support device 100 functions as a "transport vehicle." The procedure for causing the construction support device 100 to function as a "transport vehicle" will be described later in <<Method for transporting girder blocks using the construction support device>>.

[0046] In the construction support device 100 described above, as shown in FIG. 2, a machine room R in which a generator and the like are mounted is arranged on a support stand 21 constituting a support mechanism 20, and supplies power to the lifting mechanism 30 and the like.

[0047] <<<Method of transporting girder block G using construction support device>>> A method for transporting girder blocks G using the construction support device having the above-mentioned configuration will be explained below with reference to Figures 4 to 7, using the superstructure widening work of a road bridge B using a central median opening A as an example.

[0048] <<Outline of superstructure widening work>> In the superstructure widening work for road bridge B, as shown in Figures 5(a) and (b), the wall parapet W on the side of the median strip opening A on both the uphill and downhill lanes of road bridge B is cut and removed. Next, the median strip opening A is used to lift girder block G from the ground, and this lifted girder block G is transported to the vicinity of the planned position for widening the superstructure at the median strip opening A. After this, girder block G is added to the cross beam D of road bridge B so as to close the median strip opening A, and the superstructure is widened by merging the median strip.

[0049] In this embodiment, the steps for performing the lifting work, which is part of the above-mentioned median strip merging work, to lift the girder block G from the ground onto the road bridge B using the median strip opening A, and the long-distance transport work to transport the lifted girder block G to a destination away from the lifting position (near the planned location for widening the superstructure of the median strip opening A) using the construction support device 100 are shown below.

[0050] <Moving process of the construction support device> First, as shown in FIG. 4(a), a pair of guide rails 50 are laid across both sides of a median strip opening A, and the construction support device 100 is carried onto a road bridge B.

[0051] 4(B), the construction support device 100 is moved along the guide rail 50 using the traveling means 22 and stopped near the lifting position of the girder block G at the median strip opening A. As a result, the construction support device 100 is positioned so that the pair of girder members 11 face in the extension direction of the median strip opening A (the bridge axis direction).

[0052] ≪Building formation process≫ When the construction support device 100 is stopped near the lifting position of the girder block G, as shown in Fig. 5(a), the outriggers 23 are extended and the frame 10 is supported by the outriggers 23. This makes the frame 10 ready to be handled like a "building".

[0053] <Overhead crane construction process> Simultaneously with or before or after this work, the length of each of the column members 13 is adjusted using the extension mechanism 132 so that the girder members 11 and the beam members 12 are approximately horizontal. In this embodiment, as shown in Figures 4(a) and (b), an example is given of a case where the installation position of the construction support device 100 is inclined in the bridge axis direction (descending toward the right side of the paper) and has a step in the direction perpendicular to the bridge axis.

[0054] The adjustment work using the telescopic mechanism 132 may be performed at any time. For example, when the adjustment amount is known, as shown in Fig. 4(a), the telescopic mechanism 132 may be used to adjust the girder member 11 and the beam member 12 to be approximately horizontal at the lifting position of the girder block G before the construction support device 100 is carried onto the road bridge B.

[0055] "Approximately horizontal" means that the gradient of the running rails 111 provided on the girder member 11 shown in Figure 3 is within a range that satisfies the rail gradient allowable limit (1 / 500) specified in the crane installation guidelines, and that the horizontal difference between the left and right running rails 111 is within a range that satisfies the horizontal difference allowable limit (1 / 500) between the left and right rails specified in the crane installation guidelines, etc.

[0056] Through the above operations, the construction support device 100 is changed to a structure in which an "overhead crane" that satisfies the crane installation guidelines consisting of the lifting mechanism 30 is formed on a "building" consisting of the frame 10 supported by the outriggers 23. In other words, the construction support device 100 is in a state in which it maintains its function as a crane.

[0057] After this, the wall parapet W is cut and removed. The work of removing the wall parapet W may use the lifting mechanism 30, which is treated as the above-mentioned "ceiling crane," or other means. When using the lifting mechanism 30, the wall parapet W can be removed by following the steps of <Lifting and Transporting Process of Girder Block G> to <Long-distance Transporting Process> described below.

[0058] <Lifting and transport process of girder block G> The girder block G is transported under the elevated road bridge B using a trailer T or the like, and then the girder block G is lifted to above the road bridge B using a lifting mechanism 30.

[0059] For example, as shown in FIG. 5(b), when a long girder block G is brought in perpendicular to the extension direction (bridge axis direction) of the median strip opening A, the hoisting tool 35 of the lifting mechanism 30 is attached to the girder block G via a separately prepared hoisting device H. Then, the hoisting device H is used to rotate the girder block G by 90 degrees in the horizontal plane. After that, the hoisting device 33 is used to wind up the wire 34, and the girder block G is lifted until it is positioned at least above the load receiving means 40.

[0060] The hoisting device H may have any configuration as long as it is capable of rotating the girder block G 90 degrees in a horizontal plane. In addition, when a long girder block G is transported under the elevated road bridge B in a state in which it extends in the bridge axis direction and no rotating operation is required, the hoisting tool 35 of the lifting mechanism 30 may be attached to the girder block G without using the hoisting device H.

[0061] <Loading process> In this way, after the girder block G has been lifted to a prescribed height above the road bridge B, as shown in Figures 6(a) and 3, a plurality of joists 60 extending parallel to the beam member 12 are installed so as to span the load receiving means 40 adjacent in the extension direction of the beam member 12. Thereafter, as shown in Figure 6(b), the girder block G is lowered and unloaded onto the joists 60.

[0062] In the above-mentioned <<Lifting and Transporting Process of Girder Block G>> and <<Loading Process>>, the girder 31 and the trolley 32 of the lifting mechanism 30 are moved appropriately to appropriately adjust the positions of the hoisting device 33 and the lifting tool 35 within the frame 10. This allows the suspended girder block G to be easily lifted using the central median strip opening A, and allows the girder block G to be loaded in a stable position on the joist material 60.

[0063] <Transport cart formation process> In this way, when the girder block G is unloaded and loaded onto the load receiving means 40 via the joists 60, the outriggers of the support mechanism 20 are shortened and the frame 10 is supported by the traveling means 22, as shown in Fig. 6(b) and Fig. 7(a). This changes the construction support device 100 to a state where it functions as a "transportation vehicle." At this time, as shown in Fig. 7(a), since the load receiving means 40 is provided above the extension mechanism 132 constituting the pillar member 13, the girder block G is loaded in a horizontal position similar to the girder member 11 of the frame 10.

[0064] <Long-distance transport process> Once these operations are completed, the construction support device 100 is run along the guide rails 50 to transport the girder block G to the desired destination (near the planned position for widening the superstructure of the median strip opening A). At this time, as shown in Fig. 7(b), the gradient of the installation surface of the construction support device 100 at the destination may differ from the gradient of the source (lifting position of the girder block G) shown in Fig. 7(a). If this occurs, it is naturally expected that the girder members 11 and beam members 12 of the frame 10 will deviate from approximately horizontal.

[0065] Therefore, when lifting the girder block G after it arrives at its destination, the above-mentioned "building formation process" and "overhead crane formation process" are carried out to make the girder members 11 and beam members 12 of the frame 10 approximately horizontal as shown in Fig. 8. In this way, the construction support device 100 is changed from a state in which it functions as a "transportation vehicle" to a state in which it has an "overhead crane" consisting of the lifting mechanism 30 and ensures its function as a crane. Then, the lifting process of the girder block G is carried out using the lifting mechanism 30 that can be regarded as an "overhead crane".

[0066] In this way, by placing the construction support device 100 across the median opening A, the space above the median can be effectively utilized, making it possible to carry out lifting and transporting work for girder blocks G in various construction works related to the road bridge B without traffic restrictions or with only minor construction restrictions, thereby contributing to preventing traffic congestion and accidents.

[0067] As described above, when the installation surface has an inclined step, the construction support device 100 supports the frame 10 with the outriggers 23 and treats it as a "building", and adjusts the length of the column members 13 to make the girder members 11 and the beam members 12 approximately horizontal. In this way, the lifting mechanism 30 can be treated as an "overhead crane" installed in the "building".

[0068] Therefore, regardless of the condition of the installation surface at the construction site, the construction support device 100 can be ensured to function as a crane, making it possible to support on-site work related to lifting and transportation.

[0069] Furthermore, by providing the load receiving means 40 on the column member 13, the construction support device 100 can be used as a transport vehicle that transports the load on the load receiving means 40 to a distant destination. This makes it possible to perform a series of operations from lifting the girder block G to long-distance transportation using only the construction support device 100, thereby improving the efficiency of on-site work.

[0070] The construction support device and the method for lifting and transporting materials and equipment of the present invention are not limited to the above-described embodiments, and various modifications are possible without departing from the spirit and scope of the present invention.

[0071] For example, in this embodiment, the superstructure widening work of road bridge B using the median strip opening A is given as an example, but the construction support device 100 can be adopted at any construction site.

[0072] Furthermore, the column members 13 may be provided with sliding bearings that absorb external forces acting in the horizontal direction (sideways) when the construction support device 100 is subjected to such forces, or with vibration absorbing materials that absorb vibrations acting in the vertical direction (up and down). In this way, when the construction support devices 100 are arranged across the median strip opening A, if the upward and downward deck slabs behave differently in the up and down and left and right directions due to an earthquake, vehicle traffic, or the like, the vibration absorbing materials and sliding bearings can absorb these, thereby preventing damage or malfunction of the frame 10.

[0073] Any vibration absorbing material may be used, for example, a vibration-damping rubber may be interposed between the column body 131 and the extension mechanism 132, or an accumulator may be installed inside the extension mechanism 132. Any sliding bearing may be used, for example, an elastic sliding bearing or a rigid sliding bearing may be provided between the column member 13 and the support mechanism 20.

[0074] Furthermore, in the present embodiment, the saddle 36 provided on the lifting mechanism 30 moves on the traveling rail 111 provided on the upper part of the beam member 11, but the present invention is not limited to this. For example, a traveling rail 111 parallel to the beam member 11 may be attached to the lower surface of a beam member 12 provided on the frame 10, and the saddle 36 may be moved in a hanging manner along the traveling rail 111. In this case, it is preferable to provide at least two beam members 12 supporting the traveling rail 111 on the frame 10.

[0075] In addition, in Figure 5 (b), the lifting device 35 of the lifting mechanism 30 is attached to the girder block G via the lifting device H, and the girder block G is rotated horizontally using the lifting device H. However, for example, the lifting mechanism 30 may be provided with equipment for moving the lifting device 35 itself relative to the frame 10 to rotate the girder block G horizontally.

[0076] Furthermore, the joists 60 on which the girder blocks G are loaded in the loading process may be attached to the frame 10 or may be brought in separately. When attached to the frame 10, for example, as shown in Fig. 9, the joists 60 are stored in an upright position, arranged in pairs on both sides of the beam member 12. When in use, the joists 60 may be rotated vertically so as to project toward the inside of the frame 10, and placed in a lying position, and supported by the load receiving means 40.

[0077] 10(a) and 10(b), the load receiving means 40 may be continuous in a direction parallel to the girder member 11, and the joists 60 may be configured to slide on the upper surface. In this way, as shown in Fig. 10(a), multiple joists 60 can be arranged at any interval, and after the girder block G is loaded and transported, the multiple joists 60 can be stored by moving them to one end of the load receiving means 40, as shown in Fig. 10(b).
