Description

Technical Field

[0001] The present invention relates to a sliding method and a sliding device used for constructing a roof structure of a large-span building such as an indoor sports facility like an arena or a large exhibition facility.

Background Art

[0002] As a method for constructing a roof structure of a building with a long bay length between large beams such as an indoor sports facility like an arena or a large exhibition facility, a sliding method has sometimes been adopted. The sliding method is characterized by repeating the process of dividing the roof structure of these buildings with a long bay length into several partial structures, assembling the partial structures at a fixed location, and sequentially feeding them out.

[0003] For example, in the case of the roof structure of a building with a very long bay length, from the perspective of construction efficiency, a sliding method using a method of continuously pulling a long distance by winding a long wire has sometimes been used.

[0004] Also, in a method that does not use a wire, a method is known in which a hydraulic jack is attached in front of the leading partial structure and is pulled on a slide rail by a telescopic method of the piston rod of the hydraulic jack (see FIG. 4).

[0005] In these conventional methods, it is necessary to secure a place to install a part of the sliding device in front (outside the building) of the final sliding point of the roof structure. However, depending on the site conditions of the building, it may be difficult to secure such a place, and the sliding method in the above conventional methods cannot be applied.

[0006] On the other hand, a method of pushing out using a hydraulic jack from the rear of the roof structure does not require such a place in front (outside the building) of the final sliding point of the roof structure, and it is only necessary to secure a place required for assembling the partial structure and installing the sliding device (such as a hydraulic jack) behind (outside or inside the building) the sliding start point of the roof structure.

[0007] In particular, if space for assembling the partial frame and installing the sliding device (hydraulic jack, etc.) cannot be secured on the outside of the building behind the starting point of the roof frame's slide, these spaces will have to be secured on the inside of the building. In that case, it is desirable that the space occupied by the sliding device on the inside of the building is not large, so it is desirable that the sliding device be as compact as possible.

[0008] Prior art relating to sliding construction methods for roof structures includes, for example, the invention described in Patent Document 1. Patent Document 1 discloses an invention for a construction method that suppresses the horizontal force at the base of the columns generated by the building's own weight and pulls the long sliding distance using a compact traction device, which is a problem when using a sliding construction method for buildings with a rigid frame structure in the span direction and a long girder length.

[0009] The traction device consists of a cylinder jack unit installed along a slide rail at a predetermined distance forward from the leading partial frame that is moved by sliding, and a traction member connecting the cylinder jack unit and the partial frame. The traction device advances the partial frame by pulling the traction member using a measuring method caused by the repeated extension and retraction of the piston rod of the cylinder jack unit.

[0010] In the sliding construction method disclosed in Patent Document 1, it is necessary to secure a location where the cylinder jack and traction member can be installed in front of (outside the building) the final point of sliding movement of the leading partial frame.

[0011] In other words, it cannot be applied if the site is small and such a place cannot be secured, but this point is not mentioned and no suggestion is given. [Prior art documents] [Patent Documents]

[0012] [Patent Document 1] Patent No. 6636091 [Overview of the project] [Problems that the invention aims to solve]

[0013] The present invention provides a sliding construction method and a sliding device that can be implemented using a compact and simple sliding device, even when constructing structures such as roof frames using a sliding method, for example, when the site is narrow and it is not possible to secure a place to assemble the roof frame or install the sliding device on the outside of the building in the sliding direction. [Means for solving the problem]

[0014] The present invention provides a means for solving the aforementioned problems, which is a sliding construction method for erecting a steel-framed superstructure on the lower structural frame of a building, (1) With the support point of the first slidable partial frame placed on a slide rail installed on the substructure, one end of a hydraulic jack is connected to the rearmost support point of the partial frame, and the other end of the hydraulic jack is connected to a reaction force support provided on a part of the upper part of the substructure. (2) After step (1), the piston rod of the hydraulic jack is extended, and the initial partial frame is pushed out by a predetermined stroke.

[0015] At this point, if the necessary open space for assembling the second partial frame structure has not been secured upon completion of process (2), proceed to the next process (3); otherwise, proceed to process (10).

[0016] (3) After the completion of step (2), the other end of the hydraulic jack is removed from the reaction force support, the piston rod of the hydraulic jack is retracted, and the hydraulic jack body moves forward. (4) A first measuring member is inserted to fill the gap between the reaction force support portion and the other end of the hydraulic jack that was created in step (3), and both ends of the first measuring member are connected to the reaction force support portion and the other end of the hydraulic jack. (5) After step (4), the piston rod of the hydraulic jack is extended, and the initial partial frame is pushed out further by a predetermined stroke.

[0017] At this point, if the necessary space width for assembling the second partial frame structure has not been secured upon completion of step (5), proceed to the next step (6); otherwise, proceed to step (10).

[0018] (6) After the completion of step (5), the other end of the hydraulic jack is removed from the first measuring material, the piston rod of the hydraulic jack is retracted, and the hydraulic jack body moves forward. (7) A second measuring member is inserted to fill the gap between the first measuring member and the other end of the hydraulic jack that was created in step (6), and both ends of the second measuring member are connected to the first measuring member and the other end of the hydraulic jack. (8) After step (7), the piston rod of the hydraulic jack is extended, and the initial partial frame is pushed out further by a predetermined stroke. (9) Processes (6) to (8) are repeated at least once in order to secure the necessary space width for the assembly of the next section of the frame to be sent out.

[0019] (10) After the width of the space necessary for assembling the second partial frame to be sent out has been secured, all the measuring materials are removed and steps (1) to (9) are performed in order to send out the second partial frame. (11) The process is repeated from (1) to (10) until all the partial frames that are subject to sliding movement have been extruded. This sliding construction method is characterized by including the above steps.

[0020] (12) After all of the aforementioned partial frames have been moved by sliding, the remaining superstructures to be installed on the substructure can be erected separately.

[0021] Furthermore, a sliding device used in the aforementioned sliding method, (1) A hydraulic jack having a piston rod is disposed between the trailing fulcrum portion of a partial framework of a superstructure placed on a slide rail installed on a lower structure body of a building and a reaction force support portion provided on a part of the upper portion of the lower structure body located behind the trailing fulcrum portion. (2) One end of the hydraulic jack (for example, the tip of the piston rod) is connected to the trailing fulcrum portion of the partial framework, and the other end of the hydraulic jack (for example, the rear end of the hydraulic jack) is connected to the reaction force support portion or to a telescopic member that has been inserted and installed between the reaction force support portion and the hydraulic jack.

[0022] (3) Connecting plates for connecting to the reaction force support portion, the hydraulic jack, or an adjacent telescopic member are attached to both ends of the telescopic member. (4) Slide guide plates are erected on both sides of the sliding surface of the slide rail at a dimensional interval such that the connecting plates of the telescopic member generally inscribe, for example, like a channel steel with both flanges facing upward.

[0023] Since the side ends of the connecting plates of the telescopic member contact the inner surface of the slide guide plate, the telescopic member is restricted from moving in the horizontal direction orthogonal to the axis. A slide device used in a slide method, characterized by comprising the above configuration.

[0024] The connection portions at both ends of the hydraulic jack may be rotatable as a pin joint. In that case, since the hydraulic jack can be inclined, even if there is a certain level difference between the height of the trailing fulcrum portion and the height of the reaction force support portion, the connection can be made without problem. If there is no level difference, there is no problem even if it is not a pin joint.

[0025] Further, the present invention is a slide device used in a slide method, characterized by having a floating restraint member for suppressing the lifting of the telescopic member in the slide device.

[0026] The aforementioned lift-up restraining material is inserted between the reaction force support section and the hydraulic jack and is used to prevent the multiple connecting inch members from moving upward (lifting up) when subjected to a compressive force. [Effects of the Invention]

[0027] Because the present invention is carried out by the means described above, it has the following effects. (1) The installation location for the sliding device only needs to be secured behind the partial frame to be slid, and unlike the conventional sliding construction method described above, there is no need to secure extra space on the front outdoor side of the building until the sliding is completed. Therefore, sliding construction can be carried out without problems even in narrow cases where there is no site on the front outdoor side of the building.

[0028] (2) In the case of a narrow space where there is no land on the rear outside of the building, it is necessary to set up a work platform for assembling the partial frame inside the building, but since a reaction force support part for the hydraulic jack that pushes out the partial frame is provided on a part of the upper part of the substructure frame, the sliding work can be carried out without any problems.

[0029] (3) The work cycle for pushing out the partial frame can be performed in a fixed location (behind the partial frame), and since it is a simple operation involving the repeated extension and retraction of the hydraulic jack's piston rod and the insertion and removal of the measuring material, the work efficiency is good.

[0030] (4) If both ends of the hydraulic jack are pin-connected, it is possible to connect them without any problems even if there is a certain difference in height between the rearmost support point of the partial frame and the reaction force support point.

[0031] (5) If the travel distance of the extruding section frame in one cycle is constant, the same measuring material inserted between the reaction force support and the hydraulic jack can be reused repeatedly.

[0032] (6) The measuring member's movement (lifting) in the horizontal direction perpendicular to the axis and upward direction is suppressed by the slide guide plates on both sides of the slide rail and the lifting restraint members. Therefore, even if multiple measuring members are connected and the length increases, the compressive axial force from the hydraulic jack can be safely and reliably transmitted to the reaction force support. [Brief explanation of the drawing]

[0033] [Figure 1] This diagram illustrates the procedure for one cycle of pushing out a partial frame 4 of the superstructure of a building in the sliding construction method according to the present invention, where (a) is a plan view showing the state immediately before the first partial frame 4 starts sliding, (b) is the state in which the partial frame 4 has been pushed out by a predetermined length s by the piston rod 5a of the hydraulic jack 5, (c) is the state in which the first measuring member 7 has been inserted between the reaction force support part 6 and the hydraulic jack 5, and (d) is the state after the second pushing out by the piston rod 5a. [Figure 2] This diagram illustrates the continuation of the embodiment shown in Figure 1, where (e) shows the state in which the second measuring member 7 is inserted between the first measuring member 7 and the hydraulic jack 5, (f) shows the state after the third pushing by the piston rod 5a, (g) shows the state in which the third measuring member 7 is inserted between the second measuring member 7 and the hydraulic jack 5, (h) shows the state after the fourth pushing by the piston rod 5a, and (i) shows the state in which one cycle of sliding movement is completed, the hydraulic jack 5 is returned to state (a), and the second partial frame 4 (dotted line) is assembled. [Figure 3] This shows an example of the connection between the rearmost support point 4a of the partial frame 4, the hydraulic jack 5, and the measuring member 7, where (a) is a side view, (b) is a plan view, (c) is a view of the section from L-L in (b), and (d) is a view of the section from C-C in (b). [Figure 4] This is an example of a conventional sliding construction method using hydraulic jacks 50, 50, ... and traction members 60, 60. (a) is a side view showing the state immediately before the start of sliding, and (b) is a side view showing the state after all parts of the frame 4 to be slid have finished moving. [Modes for carrying out the invention]

[0034] An embodiment of the sliding method according to the present invention will be described with reference to Figures 1 to 3. As shown in Figure 1(a) (arrows indicate the sliding direction), slide rails 2, 2 are laid on the lower structural frame 1 of the building along the entire length of the building, and a frame assembly platform 3 is provided on one end of the building's interior. (1) With the support points 4a, 4a, ... of the first partial frame 4 to be slid on the slide rails 2, 2, the rearmost support points 4a, 4a of the partial frame 4 are connected to the tips of the piston rods 5a, 5a of the hydraulic jacks 5, 5, and the rear ends of the hydraulic jacks 5, 5 are connected to the reaction force support parts 6, 6 provided on the corner column heads 1a, 1a of the lower structural frame 1 by adjusting the extension and retraction of the piston rods 5a, 5a of the hydraulic jacks 5, 5 (Figure 1(a)). (2) After step (1), the piston rods 5a, 5a of the hydraulic jacks 5, 5 are extended, and the initial partial frame 4 is pushed out by a predetermined stroke s (in the direction of the arrow) (Figure 1(b)).

[0035] At this point, if the open space width w required for assembling the second partial frame 4 to be sent out has not been secured upon completion of process (2), proceed to the next process (3); otherwise, proceed to process (10).

[0036] (3) After the completion of step (2), the rear ends of the hydraulic jacks 5, 5 are detached from the reaction force support parts 6, 6, the piston rods 5a, 5a of the hydraulic jacks 5, 5 are retracted, and the bodies of the hydraulic jacks 5, 5 move forward. (4) In the process of inserting measuring members 7, 7 to fill the gap between the reaction force support parts 6, 6 and the rear ends of the hydraulic jacks 5, 5 that was created in step (3), the ends of the measuring members 7, 7 are connected to the reaction force support parts 6, 6 and the rear ends of the hydraulic jacks 5, 5 (Figure 1(c)). (5) After step (4), the piston rods 5a, 5a of the hydraulic jacks 5, 5 are extended, and the initial partial frame 4 is pushed out further by a predetermined stroke s (in the direction of the arrow) (Figure 1(d)).

[0037] At this point, if the open space width w required for assembling the second partial frame 4 to be sent out has not been secured upon completion of process (5), proceed to the next process (6); otherwise, proceed to process (10).

[0038] (6) After the completion of step (5), the rear ends of the hydraulic jacks 5, 5 are removed from the measuring members 7, 7, the piston rods 5a, 5a of the hydraulic jacks 5, 5 are retracted, and the bodies of the hydraulic jacks 5, 5 move forward. (7) A second set of measuring members 7, 7 is inserted to fill the gap between the measuring members 7, 7 and the rear ends of the hydraulic jacks 5, 5 that was created in step (6), and both ends of the measuring members 7, 7 are connected to the first set of measuring members 7, 7 and the rear ends of the hydraulic jacks 5, 5 (Figure 2(e)). (8) After step (7), the piston rods 5a, 5a of the hydraulic jacks 5, 5 are extended, and the initial partial frame 4 is pushed out further by a predetermined stroke s (in the direction of the arrow) (Figure 2(f)).

[0039] (9) Process (6) to (8) is repeated at least once in order to secure the open space width w necessary for the assembly of the next section frame 4 to be sent out (Figure 2(g) to (h)). (10) After securing the open space width w where the next section frame 4 (shown by dashed line) to be sent out will be assembled, all the measuring members 7, 7, ... are removed, and the hydraulic jacks 5, 5 are installed in the same way as in step (1) in order to send out the next section frame 4 (Figure 2(i)).

[0040] (11) The process of repeating steps (1) to (10) until the extrusion of all the partial frames 4, 4, ... that are subject to sliding movement is completed.

[0041] (12) After all the partial frames 4, 4, ... have finished sliding, the slide rails 2, 2, hydraulic jacks 5, 5, measuring members 7, 7, ... and reaction support parts 6, 6 are removed, and the remaining superstructure to be installed on the substructure frame 1 is erected separately (not shown).

[0042] The slide rails 2, 2, hydraulic jacks 5, 5, measuring members 7, 7, ... and reaction force support parts 6, 6 can be removed after the support points 4a, 4a, ... of each of the partial frames 4, 4, ... are fixed in their respective positions on the substructure frame 1.

[0043] This embodiment is a sliding construction method characterized by including the above steps. Therefore, in the case of a narrow site where there is no site on the rear outdoor side of the building (left edge of the page in Figure 1), as shown by the site boundary line (shown as a dashed line) in Figure 1, the work platform 3 for assembling the partial frame 4 must be installed inside the building. However, since the reaction force support parts 6, 6 for the hydraulic jacks 5, 5 that push out the partial frame 4 are provided on a part of the upper part of the substructure frame 1, the sliding construction can be carried out without any problems.

[0044] Figure 4 shows an example of a sliding construction method using conventional hydraulic jacks 50, 50, ... and traction members 60, 60. Since the hydraulic jacks 50, 50, ... and traction members 60, 60 are positioned in front of the partial frame 4, when the sliding movement of all partial frames 4, 4, ... is complete (Figure 4(b)), temporary structures 30, 30 and their installation locations are required outside the building to hold the hydraulic jacks 50, 50, ... and traction members 60, 60.

[0045] However, as shown by the site boundary line (indicated by a dashed line) in Figure 4(a), in narrow cases where there is no site on the front outdoor side of the building (right edge of the page in Figure 4(a)), the temporary structures 30, 30 would extend outside the site. In contrast, in the present invention, such temporary structures 30, 30 and their installation location are unnecessary, so there is no problem even in such narrow site conditions.

[0046] Furthermore, an embodiment of the sliding device used in the sliding method of the present invention consists of the following configuration. Refer to Figure 3. (1) A hydraulic jack 5 having a piston rod 5a is positioned between the rearmost support point 4a of the partial frame 4 of the superstructure, which is placed on a slide rail 2 installed on the lower structural frame 1 of the building, and the reaction force support part 6 provided on the corner column head 1a of the lower structural frame 1 located behind the rearmost support point 4a. (2) One end of the hydraulic jack 5 (the tip of the piston rod 5a in Figure 3) is connected to the rearmost support point 4a of the partial frame 4, and the other end of the hydraulic jack 5 (the rear end of the hydraulic jack 5 in Figure 3) is connected to a reaction force support part 6 provided on the corner column head 1a of the substructure frame 1 (not shown), or to a measuring member 7 inserted and installed between the reaction force support part 6 and the hydraulic jack 5, as shown in Figure 3.

[0047] Furthermore, if the end connections of the hydraulic jack 5 and the piston rod 5a are made rotatable by pin joints, the hydraulic jack 5 can be tilted, so even if there is a certain difference in height between the rearmost pivot point 4a and the reaction force support part 6, the connection can be made without any problems.

[0048] (3) Both ends of the measuring members 7, 7 are fitted with reaction force support parts 6 or hydraulic jacks 5 or connecting plates 7a, 7a for connecting to adjacent measuring members 7. (4) Slide guide plates 2a, 2a are erected on both sides of the sliding surface of the slide rail 2, for example, on a channel steel with both flanges facing upward, at a dimensional interval that allows the connecting plate 7a of the inch member 7 to be roughly inscribed inside (see Figure 3(c)). These slide guide plates 2a, 2a restrict (buckling restraint) the movement of the inch members 7, 7, ... in the horizontal direction perpendicular to their axis, even when subjected to axial force from the hydraulic jack 5.

[0049] Furthermore, as shown in Figure 3(d), by attaching the lift-restraining member 8 to suppress the lifting of the inch members 7, 7, ..., it is possible to prevent the inch members 7, 7, ... from lifting upward when subjected to axial force from the hydraulic jack 5 (buckling restraint).

[0050] As described above, with this sliding device, after pushing out the partial frame 4 with the hydraulic jacks 5, 5, the process involves repeatedly inserting or removing the shank members 7, 7, ... between the reaction force support parts 6, 6 and the hydraulic jacks 5, 5. However, since these operations are simple, repetitive tasks performed in a limited, fixed location, the work efficiency is good.

[0051] On the other hand, in the conventional sliding construction method using hydraulic jacks as shown in Figure 4 (see, for example, Patent Document 1), it is necessary to move the positions of the hydraulic jacks 50, 50 and the traction members 60, 60 further forward each time the furthest partial frame 4 moves forward. Compared to this, the present invention can be said to be a sliding construction method and sliding device with significantly improved workability. [Industrial applicability]

[0052] Since the sliding device according to the present invention is compact and simple, it enables smooth and efficient sliding construction when constructing superstructures such as roofs using the sliding construction method according to the present invention. In particular, it can be easily and safely applied even when the site is narrow and it is not possible to secure a place to assemble the partial framework of the superstructure or a place to install the sliding device on the outside of the front and rear of the building. Therefore, the present invention expands the range of application of the sliding construction method for constructing roof frameworks of buildings with long spans between main beams and greatly contributes to the improvement of construction technology.
