Description

  The present invention relates to a long roof plate installation device such as a folded plate roof material and a roof plate construction method using the same.

  In construction of long roof sheets for buildings, metal sheets wound in a coil shape are molded with a roll forming machine, cut into a predetermined length to form long roof sheets, and aligned in order from the edge of the roof. And fix to the beam.

  In the case of a long roof board material having a length of about 50 m or more, it is supported and moved at intervals of 5 to 10 m. If it does so, the load per location will be about 20-30 kg. If these are supported manually, there is a risk of heavy labor of working on the middle waist on a roof with poor scaffolding. In order to avoid this, a roofing material transport device and a roofing material installation device are disclosed. The roof plate must be placed exactly between the folded plate holders and the eaves must be aligned.

  As a transport method, for example, Patent Document 1 describes a folded-plate roofing method for transporting a roof plate material with a sled-type transport jig. This is a transport method in which a wooden sled with a folded plate is pushed and slid on the folded plate roof.

  Further, Patent Document 2 describes a folded plate transporting device having a slide mechanism and a lifting mechanism on a sled and a method for constructing a folded plate roof material using the folded plate roofing device. After the folded plate is lifted at the folded plate storage, the folded plate transporting device moves the folded plate load onto the sled using the slide mechanism, stabilizes the position of the center of gravity, and then moves on the roof. At a predetermined position, the folded plate is projected forward by the slide mechanism and placed between the folded plate holders.

  A configuration example of the long roof sheet material installation device 2 according to the present invention will be described with reference to FIGS. 1 and 2A, 2B, and 2C. The long roof sheet material installation device 2 includes a slide base 21, a support column 22, a suspension arm 23, a hoisting machine 3, and a roof material holder 4 as main members. The hoisting machine 3 is suspended from the suspension arm 23 by a suspension wire 31, and the roof material holder 4 is suspended from the hoisting machine 3 by a suspension wire 32. The roof plate material 5 to be installed, for example, the folded plate 51, is gripped by a grip portion 42 provided on the roof material holder 4. The vertical movement of the folded folded plate 51 is caused by the winding operation and the rewinding operation of the hoisting machine 3. The movement of the H-shaped steel material 1 in the direction is due to the sliding operation of the sliding base 21.

  FIG. 2C is an enlarged front view of the sliding base 21. As shown in the figure, the sliding pedestal 21 is provided with a straddling portion 212 mounted on the folded plate holder 11 and pedestal side portions 211 on both sides thereof. The cross-sectional shape is a substantially U-shaped pedestal. The folded plate holder 11 is fixed to the upper surface of the H-shaped steel 1 by welding or bolting at regular intervals. The sliding pedestal 21 is arranged so that both pedestal side portions 211 sandwich the folded plate holder 11 and is independent from the H steel material 1 in a substantially floating state. Although there is some play space between the side of the folded plate holder 11 and the pedestal side portion 211 and does not hinder sliding, the direction perpendicular to the direction of the H-shaped steel material 1, that is, the folded plate 51 is wound. The backlash in the longitudinal direction is minimized.

  A synthetic resin plate 213 can be attached to the sliding surface of the straddling portion 212 of the sliding base 21. This prevents the top end of the folded plate holder 11 from being damaged and reduces the resistance when the sliding base 21 slides. In the first embodiment of the long roof sheet material installation device 2 of the present invention, the support column 22 is fixed to the slide base 21, and the suspension arm 23 is fixed to the support column 22. Then, in order to slide the slide base 21 in the direction of the H-type steel material 1 in a state where the folded plate 51 is suspended via the roof material holder 4, the operator manually pushes the suspension arm 23. .

  A stopper pin 241 can be provided on the slide base 21. The stopper pin 241 is a pin that penetrates a hole provided in both pedestal side portions 211 and is detachably provided. The stopper pin 241 is biased by a spring (not shown) so as to penetrate the hole. ing. The penetrating stopper pin 241 contacts the folded plate holder 11 to prevent the sliding base 21 from sliding. The stopper pin 241 can be inserted / removed by the operation lever 25 via the operation wire 26. If the operation lever 25 is released, the stopper pin 241 penetrates the hole by the bias of the spring, and the sliding movement of the sliding base 21 is prevented. When the operator grasps the operation lever 25, the stopper pin 241 is pulled out from the hole, and the sliding base 21 is slidable. When the hand is released from the operation lever 25, the stop pin 24 prevents the movement again.

  In this embodiment, the stopper pin 241 is realized using a mechanism for pressing a brake pad of a bicycle. However, the present invention is not limited to this, and any mechanism may be used as long as the function of preventing the movement of the slide base 21 can be actuated or released by operating the operation lever 25. This mechanism will be referred to as a pedestal movement prevention mechanism 24.

  The suspended folding plate 51 is moved up and down by operating the hoisting machine 3. The hoisting machine 3 may be a manual type or an electric type. Further, even with a hoisting machine that does not have electric power, the hoisting machine 3 may be operated by using the power of the electric impact driver by engaging the electric impact driver with the hoisting shaft.

  The long roof sheet material installation device 2 of the present invention is lighter, and handling on the roof, in particular, a sliding operation performed across the folded plate receiver 11 becomes easier. By the way, if the long roof board | plate material which consists of an iron plate with a thickness of 0.8 mm is suspended at intervals of 7 to 8 m, a load of about 30 kg is applied to each suspension device. Therefore, the long roof sheet material installation device 2 of the present invention needs to be configured on the assumption that this folded plate load is applied to the suspension arm 23. In particular, the sliding base 21 requires a certain amount of weight.

  FIG. 3 is a diagram showing the positional relationship between the load applied to the long roof sheet material installation device 2 of the present invention and the center of gravity. As described above, while the sliding base 21 requires a certain amount of weight, the column 22 and the suspension arm 23 are preferably light if the required strength is satisfied. Therefore, for example, if the support 22 and the suspension arm 23 are lightly configured and the slide base 21 is configured with a substantially uniform weight, the center of gravity position of the long roofing sheet material installation device 2 itself is substantially the center of the slide base 21. It becomes G1. It can be assumed that a load W1 is applied to G1. When the folded plate load W2 is suspended, the folded plate load W2 is applied to the central portion G2 of the folded plate 51.

  Then, the center of gravity of the long roof sheet material installation device 2 on which the folded plate 51 is suspended moves to, for example, G3, and the total load W1 + W2 is applied thereto. At this time, it is necessary to design the position of the suspension wire 31 suspended on the suspension arm 23 and to increase the weight of the slide base 21 so that the center of gravity G3 does not come off from below the slide base 21.

  When the weight of the slide base 21 is insufficient, the position of the center of gravity G3 with respect to the total load W1 + W2 is moved to the right side from the slide base 21, and a moment is applied to cause the switch to fall clockwise.

  Next, a roof plate construction method using the long roof installation device 2 according to the first embodiment of the present invention will be described. Drawing 4 is a figure explaining the long roof board construction method using long roof installation device 2 concerning a 1st embodiment. In FIG. 4A, it is assumed that three roof boards 52 have been constructed on the right side. A folded plate 51 to be constructed next is temporarily placed on the folded plate temporary placing table 6. The long roof board installation apparatus 2 according to the first embodiment is disposed adjacent to the constructed roof board 52 across the folded plate holder 11 that is still exposed. The suspension arm 23 projects over the roof plate 52 that has been constructed. The folded plate 51 is held by the roof material holder 4 suspended on the suspension arm 23. This is an operation on the roofed roof plate 52.

  Next, the hoisting machine 3 is appropriately wound up and the folded plate 51 is floated from the folded plate temporary placing table 6. Then, as shown in FIG. 4B, the suspension arm 23 is pushed forward while grasping the operation lever 25. In the figure, the button is pushed leftward. By grasping the operating lever 25, the stopper pin 241 is pulled out of the hole of the sliding base 21 and can slide, so that the sliding base 21 moves forward. When the operation lever 25 is released when the folding plate 51 is moved by the width, the stopper pin 241 is inserted into the hole, and the position of the sliding base 21, that is, the long roof plate installation device is fixed.

  Here, a gap having a width corresponding to one folded plate is vacant between the slide base 21 and the roofed roof plate 52. Therefore, as shown in FIG. 4C, the hoisting machine 3 is operated to lower the folded plate 51 onto the folded plate receiver 11 at an appropriate speed. Since the folded plate 51 is suspended via the suspension wires 31 and 32, it can be slightly adjusted and moved in the width direction and the longitudinal direction while being lowered. Since the lowering is performed while adjusting and moving in this way, there is an effect that it is easy to arrange the folded plates at the eaves.

  The next folded plate 51 is prepared on the newly constructed roof plate. The folded plate can be moved to a desired position on the roof by using a sled-type transport jig disclosed in Patent Document 1, or by a cart with many rollers or a cart with an infinite rail. It may be carried by a carriage that moves on rails. If the folded plate 51 is prepared at the edge of the roofed roof plate 52, a long roofboard can be constructed by performing the procedure shown in FIGS. 4 (A) to (C).

  FIG. 5 is a diagram of the folding plate installation work when the longitudinal direction of the folded plate is viewed from left to right. The folded plate 51 suspended by a plurality of long roof plate installation devices 2 can be lowered slowly by operating the hoisting machine 3, and can be lowered because it is not adjusted and moved several millimeters in the longitudinal direction. it can. As a result, the folded plates at the eaves can be easily arranged.

  FIG. 6 is a construction flow of the roof plate material 5 such as the folded plate 51 by the long roof plate installation device according to the first embodiment of the present invention described above. In FIG. 6, the roof board | plate material 5 is prepared in the edge of the construction top roof board 52 area | region (step a1).

  Next, the slide base 21 is disposed on the folded plate holder 11 adjacent to the edge of the region of the roof plate 52 that has been constructed. Or, it is already arranged (step a2). Then, the roof plate material 5 is suspended by the roof plate holder 4 and the hoisting machine 3 (step a3).

  With the pedestal movement preventing function disabled by the operation lever 25, the suspension arm 23 is pushed to move the sliding pedestal 21 (step a4). The slide base 21 stops when it has moved by the width of the roof plate material 5, and the base movement prevention mechanism is activated (step a5).

  Next, the hoisting machine 3 is operated to adjust the position in the longitudinal direction and the width direction, and the roof plate material 5 is installed at a predetermined position between the folded plate receivers 11. And the roof board | plate material 5 is fixed to the folded-plate receiver 11 (step a6). One roof sheet material is constructed by the above construction flow.

  The use of the long roof plate installation device according to the first embodiment of the present invention has the effect of eliminating the heavy labor of lifting the folded plate 51 manually and lowering it to a predetermined position. In addition, since the folded plate can be moved up and down using the hoisting machine 3, the folded plate 51 can be lowered slowly, and the folded plate 51 can be installed while adjusting the longitudinal direction so that the eaves are aligned. There is. Moreover, since no apparatus is inserted between the folded plate 51 to be constructed and the operator, there is an effect that the installation position can be adjusted with high accuracy.

  Further, by applying an electric impact driver to the power of the hoisting machine 3, there is an effect that it is not necessary to prepare a power source for the apparatus. Further, since the stopper pin 241 of the slide base 21 can be inserted and removed with the operation lever 25 provided on the suspension arm 23 via the operation wire 26, the operator can enter the roof of the H-shaped steel material on which the roof is not yet constructed. There is an effect that there is no and can work safely.

  The long roof slab installation device according to the first embodiment of the present invention has a structure in which a support 22 is fixed to a sliding base 21 and a suspension arm 23 is fixed to the support 22, and the unstructured H-shaped steel 1 and There exists an effect that it exists on the folded-plate receiver 11 and does not occupy the safe work space of a construction completed roof wastefully. Further, the folded plate can be lowered at an appropriate speed by using the hoisting machine 3, and there is an effect that folded plate distortion due to dropping can be prevented. Moreover, when the synthetic resin plate 213 is affixed to the sliding surface of the straddling portion 212 of the sliding base 21, there is an effect that the folded plate holder 11 is not damaged by sliding.

  Next, 2nd Embodiment of the elongate roof board installation apparatus of this invention is described. The long roof board installation apparatus which concerns on 2nd Embodiment is shown to FIG. 7 (A). The long roof sheet material installation device 2 includes a sliding pedestal 21, a support column 22, a sliding suspension arm 27, a hoisting machine 3, and a roof material holder 4 as main members. The hoisting machine 3 is suspended from the sliding suspension arm 27 by a suspension wire 31, and the roof material holder 4 is suspended from the hoisting machine 3 by a suspension wire 32. A long roof to be installed, for example, the folded plate 51, is gripped by a gripping portion 42 provided on the roof material holder 4. The vertical movement of the folded plate 51 depends on the winding operation and the rewinding operation of the hoisting machine 3. The movement of the H-shaped steel material 1 in the direction is due to the sliding operation of the sliding base 21.

  The sliding suspension arm 27 is configured to be longer than the suspension arm 23 according to the first embodiment by the width of the folded plate. The suspension arm 27 is movable while being slid in the horizontal direction while being orthogonal to the column 22. A slip prevention arm 272 is provided at the end of the sliding suspension arm 27 where the suspension wire 31 is not present. Furthermore, a push-moving mechanism 271 is provided approximately inside the folded plate width from the slip-off preventing mechanism 272.

  As described above, when the operation lever 25 is gripped, the sliding movement of the slide base is prevented by the action of the stopper pin 241, and when the operation lever 25 is released, the slide base slides on the folded plate holder 11. It becomes possible. Here, in FIG. 7A, when the sliding suspension arm 27 is pushed to the left, the push-moving mechanism 271 comes into contact with the column 22 and pushes it. At this time, if the operation lever 25 is gripped, the entire long roof plate installation apparatus 2 including the sliding base 21 can be moved to the left. Next, when the operation lever 25 is released and pulled to the right, the sliding base 21 and the support column 22 are fixed in place, so that only the sliding suspension arm 27 moves to the right. Since a slip prevention mechanism 272 is provided at the left end of the sliding suspension arm 27, the sliding suspension arm 27 stops when it is pulled out by the width of the folded plate.

  In this embodiment, the stopper pin 241 is realized using a mechanism for pressing a brake pad of a bicycle. However, the present invention is not limited to this, and a mechanism that can operate or cancel the function of preventing the sliding base 21 from moving by the operation of the operating lever 25, that is, the base movement preventing mechanism 24 can be applied.

  Similarly to the first embodiment, the long roof slab installation device of the second embodiment of the present invention needs to secure a weight on the slide base 21 so that the position of the center of gravity does not come off from the slide base 21. is there. In the second embodiment, the sliding suspension arm 27 protrudes longer by the width of the folded plate 51 than that of the first embodiment. For this reason, the position of the center of gravity is easily detached from the slide base 21 due to the weight of the folded folded plate 51. For this reason, in the second embodiment, it is necessary to increase the weight of the slide base 21 further than in the first embodiment.

  Based on FIG. 7 (A)-(C) and FIG. 8 (A)-(C), the roof-plate construction method by the elongate roof-plate installation apparatus which concerns on 2nd Embodiment is demonstrated. In FIG. 7 (A), the long roof board installation apparatus 2 is disposed adjacent to the constructed roof board 52 across the folded plate holder 11 that is still exposed.

  Here, as shown in FIG. 5B, the operating lever 25 is grasped and the sliding suspension arm 27 is pushed in the left direction, that is, the region not yet constructed. Then, since the push moving mechanism 271 pushes the support column 22, the long roof board installation apparatus 2 moves to the left. When the operation lever 25 is released when the folded plate 51 is moved by the width of the folded plate 51, the slide base 21 is fixed by the action of the stopper pin 241.

  Next, as shown in FIG. 3C, the sliding suspension arm 27 is pulled out in the right direction, that is, the region side of the roofed roof plate 52 with the operation lever 25 released. The left end of the sliding suspension arm 27 stops when it is pulled out approximately by the width of the folded plate because of the prevention mechanism 272. With the above operation, an interval corresponding to the width of the folded plate 51 is provided between the sliding base 21 and the edge of the roofed roof plate 52. And the roof-plate holder 4 suspended by the sliding suspension arm 27 by the drawing operation is on the folded plate 51 to be installed. This was prepared on the roofed roof plate 52.

  As shown in FIG. 8A, the folded plate 51 is gripped by the roof plate holder 4. And it winds up to height suitably with the hoisting machine 3. FIG. Next, as shown in FIG. 5B, the sliding suspension arm 27 is pushed without grasping the operation lever 25. Then, the sliding suspension arm 27 moves until the push-moving mechanism 271 contacts the support 22. At the same time, the folded folded plate 51 also moves and is positioned above the folded plate receiver 11 to be constructed.

  Therefore, as shown in FIG. 5C, the hoisting machine 3 is operated to lower the folded plate 51 at an appropriate speed. Since the folded plate 51 is suspended via the suspension wires 31 and 32, it can be slightly adjusted and moved in the width direction and the longitudinal direction while being lowered. Since the lowering is performed while adjusting and moving in this way, there is an effect that it is easy to arrange the folded plates at the eaves. Further, since it can be slowly lowered, it can be prevented that the folded plate 51 is violently hit against the folded plate holder 11 and the folded plate 51 is distorted. According to the method described above, the number of roof plates 52 that have been installed is increased by one, and the long roof plate installation device 2 is disposed adjacent to the roof plate 52 that has been applied across the folded plate holder 11 that is still exposed. doing. This is the state of FIG. Thereafter, roof sheets can be constructed by repeating these operations.

  In the present embodiment, the push-moving mechanism 271 is realized as a protrusion provided on the sliding suspension arm 27. However, this is not limited to this configuration, and it is only necessary to have a function of preventing the sliding suspension arm 27 from slidingly moving through the hole formed in the column 22 and pushing the column 22. Further, in this embodiment, the drop prevention mechanism 272 is realized as a protrusion provided at the end of the sliding suspension arm 27. However, this is not limited to this configuration, and it is only necessary to have a function of preventing the sliding suspension arm 27 from coming out of the hole provided in the support column 22.

  FIG. 9 is a construction flow of the roof plate material 5 such as the folded plate 51 by the long roof plate installation device according to the second embodiment of the present invention described above. In FIG. 9, the roof board | plate material 5 is prepared in the edge of the construction top roof board 52 area | region (step b1).

  Next, the slide base 21 is disposed on the folded plate holder 11 adjacent to the edge of the region of the roof plate 52 that has been constructed. Or, it has already been arranged (step b2). Here, in a state where the pedestal movement preventing function is disabled by the operation lever 25, the sliding suspension arm 27 is pushed to move the sliding pedestal 21 (step b3). The slide base 21 stops when it has moved by the width of the roof plate material 5, and the base movement prevention mechanism is enabled (step b4).

  Next, the sliding suspension arm 27 is pulled out by the width of the roof plate 5 (step b5). Then, the roof plate material 5 is suspended by the roof plate holder 4 and the hoisting machine 3 (step b6). Thereafter, in a state where the roof sheet material 5 is suspended, the sliding suspension arm 27 is pushed to move the roof sheet material 5 (step b7).

  Next, the hoisting machine 3 is operated to adjust the position in the longitudinal direction and the width direction, and the roof plate material 5 is installed at a predetermined position between the folded plate receivers 11. And the roof board | plate material 5 is fixed to the folded plate holder 11 (step b8). One roof sheet material is constructed by the above construction flow.

  The use of the long roof plate installation device according to the second embodiment of the present invention has the effect of eliminating the heavy labor of lifting the folded plate 51 manually and lowering it to a predetermined position. In addition, since the folded plate can be moved up and down using the hoisting machine 3, the folded plate 51 can be lowered slowly, and the folded plate 51 can be installed while adjusting the longitudinal direction so that the eaves are aligned. There is. Moreover, since no apparatus is inserted between the folded plate 51 to be constructed and the worker, there is an effect that the installation position can be adjusted in a systematic manner.

  Further, since the stopper pin 241 of the slide base 21 can be inserted and removed with the operation lever 25 provided on the suspension arm 23 via the operation wire 26, the operator can enter the roof of the H-shaped steel material on which the roof is not yet constructed. There is an effect that there is no and can work safely.

  The long roof slab installation device according to the second embodiment of the present invention has a structure in which a support 22 is fixed to a sliding base 21 and a suspension arm 23 is fixed to the support 22, and the unstructured H-shaped steel 1 and There exists an effect that it exists on the folded-plate receiver 11 and does not occupy the safe work space of a construction completed roof wastefully. Further, the folded plate can be lowered at an appropriate speed by using the hoisting machine 3, and there is an effect that folded plate distortion due to dropping can be prevented.

  When constructing a long roof board, about 10 long roof board installation devices 2 are required every 7 to 8 m in the longitudinal direction of the roof board material. Here, the long roof installation apparatus which concerns on 2nd Embodiment of this invention moves the slide base 21 before suspending the roof board | plate material 5, as shown to a construction flow (step b3). This means that the sliding pedestals 21 of the 10 or so long long roof installation devices can be individually moved asynchronously. From this, the long roofing board installation apparatus according to the second embodiment has an effect that it is easy to handle, particularly when constructing a long roofing board material that requires a large number of apparatuses.
