Description

[Technical field]

[0001] The present invention relates to a restraining device for temporary fencing bracing, which is used to stably restrain bracing members that stabilize a gate that can be opened and closed and installed on a temporary fencing or part of a temporary fencing, to the ground. [Background technology]

[0002] A gate that can be opened and closed freely and is installed on a temporary fence or part of it to allow vehicles to pass through for transporting construction materials and equipment is sometimes supported by bracing members erected between the gate and the ground inside the site when closed, in order to prevent the gate from tipping over due to strong winds or contact with materials and equipment, or from moving (sliding) outside the site (see Patent Documents 1 and 2).

[0003] Patent Document 1 is not an example of a brace for a gate, but in this example, part of the fastener connected to a receiving member connected to the lower end of the brace (beam member) is driven into the ground and fixed therein, thereby supporting the lower end of the brace on the ground (paragraph 0026, Figure 7).

[0004] However, when the method of fixing the fasteners underground is applied to a gate, the fasteners remain buried underground even when the bracing material is removed from the ground when the gate is opened or closed, so there is a risk that the wheels of vehicles will run over the fasteners when passing through.

[0005] In Patent Document 2, the lower end of the bracing member (support means) is connected to an anchor driven into the ground (paragraphs 0020, 0021, Figure 3), so when removing the bracing member from the ground, the same problems as with the fasteners in Patent Document 1 are faced. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP-A-10-115099 (paragraphs 0019-0028, Figures 1-10) [Patent Document 2] JP 2017-101424 A (paragraphs 0016 to 0026, Figures 1 to 3) Summary of the Invention [Problem to be solved by the invention]

[0007] As a method for preventing the wheels from running over the fasteners of Patent Document 1 or the anchors of Patent Document 2 when a vehicle passes, there is a method in which buried materials are placed in the ground in a position other than the area where the vehicle passes, as shown in Figure 6-(a). The bracing material is connected to the buried material by a swivel clamp or the like. However, in this example, the angle between the direction in which the bracing material falls or moves and the direction in which the bracing material is erected is large on a plan view, so the effect of preventing the bracing material from falling over is low, and it cannot be said to be an effective method.

[0008] As shown in Figure 6-(b), one method is to place a steel material as a weight at the position where the vehicle will pass, and connect the steel material to the bracing material using a catch clamp that can hold the bracing material while clamping part of the steel material, but the steel material must be removed (collected) when the vehicle passes, and then reinstalled after the vehicle has passed. Because the mass of the steel material is large, the work of removing and reinstalling the steel material requires time and manpower, making this an unpractical method.

[0009] As shown in Figure 6-(c), there is a method of connecting the bracing material to the steel plate laid at the vehicle passing position using a catch clamp, but the steel plate needs to be lifted in order to insert the clamp, and if the bracing material needs to be removed together with the clamp when the gate is opened, the work of removing and reinstalling is inefficient. If the clamp is left in place, there is a risk of damaging the vehicle wheels.

[0010] In view of the above background, the present invention proposes a restraint device for temporary fencing bracing, which has a simple structure yet is highly effective in preventing the bracing from falling over. [Means for solving the problem]

[0011] The restraining device for a bracing member for a temporary enclosure according to claim 1 is a restraining device for a bracing member that indirectly maintains a bracing member connected to a temporary enclosure or a gate that is a part of the temporary enclosure and that can be opened and closed in a restrained state to the ground, A fixing member having a lower member fixed to the ground or a steel plate laid on the ground, and an upper member fixed to the lower member in a state of being floating above the surface of the ground or the surface of the steel plate; a movable member having a slide member inserted under the upper member of the fixed member so as to be freely movable in and out, and a support member fixed on the slide member and to which the other end of the brace member is connected; A constituent element of the present invention is that when the sliding material of the movable member is inserted under the upper member of the fixed member, the sliding material or the support material can be engaged with the lower member or the upper member of the fixed member in the axial direction of the bracing material.

[0012] "A freely openable and closable gate that constitutes part of a temporary fence" refers to an openable and closable gate 7 that is installed at the boundary of a construction area as part of a temporary fence 8, as shown in Figure 1. "A brace connected to a temporary fence or gate" refers to the upper end of a brace 6 being connected to the temporary fence 8 itself, or to the middle part of the gate 7 in the opening and closing direction when it is closed. The lower end of the brace 6 is connected to the support member 32 of the movable member 3 that constitutes the restraint device 1. The brace 6 is not limited to being connected to one point along the length (circumferential direction) of the temporary fence 8 or gate 7, and may be connected to two or more points. "Temporary fences" include simple fences and barricades.

[0013] "Maintaining the bracing member in an indirectly restrained state to the ground" means that the bracing member 6 is indirectly restrained to the fixed member 2 fixed to the ground or to a steel plate 9 laid on the ground via the movable member 3. Even when the fixed member 2 is fixed to the ground, the bracing member 6 is indirectly restrained to the ground. The ground includes a concrete pavement 10 or an asphalt pavement.

[0014] "Lower member fixed to the ground or steel plate" means that the lower member 21 constituting the fixed member 2 is fixed directly or indirectly to the ground or steel plate 9. In the case of direct fixation, the lower member 21 is mainly fixed to the ground with anchors 5 as shown in Figures 2 and 3, and is mainly fixed to the steel plate 9 by welding or the like, but the fixing means is not important, and it may also be indirectly fixed to the ground etc. via an intermediate member.

[0015] "An upper member fixed to a lower member in a state of floating above the ground surface or the surface of the steel plate" means that when upper member 22, which constitutes fixed member 2 together with lower member 21, is fixed to lower member 21, the lower surface of upper member 22 is floating above the ground surface or the surface of steel plate 9, and sliding member 31, which constitutes movable member 3, can freely move in and out below upper member 22. "Fixed member having a lower member and an upper member" means that fixed member 2 is composed of at least lower member 21 and upper member 22. "Fixed" includes integral (integrally molded).

[0016] The shapes of the lower member 21 and the upper member 22 are not important except that the sliding material 31 can freely move in and out from under the upper member 22 of the fixed member 2, and when the sliding material 31 is inserted under the upper member 22, the sliding material 31 or the support material 32 which together with the sliding material 31 constitutes the movable member 3 can be engaged mainly horizontally with the lower member 21 or the upper member 22, and the upper member 22 can restrain the sliding material 31 from floating up.

[0017] "A sliding member inserted so as to be freely movable under the upper member of the fixed member" means that the sliding member 31 is inserted so as to be freely movable in one direction mainly between the upper member 22 of the fixed member 2 and the ground surface or the surface of the steel plate 9. "Mainly" means mainly in one direction, but also includes bending or curving in two directions.

[0018] "A support material fixed on the slide material and to which the other end of the brace material is connected" refers to a support material 32 fixed on the slide material 31, the lower end of which is connected to the support material 6 using a gripping device 4 such as a swivel clamp. The gripping device 4 is connected to the support material 32 and the brace material 6. The upper end of the brace material 6 is connected to the gripping device 4 such as a catch clamp which is connected to the center of the gate 7 as described above.

[0019] The support member 32 is fixed on top of the slide member 31 which is inserted under the upper member 22 of the fixed member 2, but as the brace member 6 is connected to the upper end of the support member 32 as shown in Figure 2, the support member 32 protrudes above the upper surface of the upper member 22 of the fixed member 2, and the gripping tool 4 is connected to the protruding section. "A movable member having a slide member and a support member" means that the movable member 3 is composed of at least the slide member 31 and the support member 32.

[0020] "When the sliding material of the movable member is inserted under the upper member of the fixed member, the sliding material or the support material engages with the lower or upper member of the fixed member" means that when the sliding material 31 is inserted under the upper member 22, the sliding material 31 may engage with the lower member 21 or the upper member 22 of the fixed member 2, or the support material 32 may engage with the lower member 21 or the upper member 22.

[0021] "The sliding material or the support material can be locked in the axial direction of the bracing material" means that when the bracing material 6 tries to move, such as by tipping over, in the erection direction (axial direction), the sliding material 31 or the support material 32 can be locked to the fixed member 2 in that direction. However, since the fixed member 2 needs to restrain the movement of the moving member 3 when the bracing material 6 tries to move, the moving member 3 will be locked to the fixed member 2 in the direction opposite to the erection side of the bracing material 6. In Fig. 2, the bracing material 6 is erected to the right of the support material 32, so the sliding material 31 or the support material 32 can be locked to the left side of the fixed member 2.

[0022] The direction in which the slide member 31 or the support member 32 is engaged is directly the axial direction (installation direction) of the bracing member 6, but when the bracing member 6 tries to move, the lower end of the bracing member 6 tries to move horizontally along the ground surface or the surface of the steel plate 9, so the slide member 31 or the support member 32 only needs to be engaged with the fixed member 2 in the horizontal direction along the axial direction of the bracing member 6. In addition, when the bracing member 6 tries to rise in the vertical direction, the slide member 31 engages with the fixed member 2 upwards, preventing the bracing member 6 from rising up.

[0023] In terms of the state in which the bracing member 6 is projected onto a plane, the lower member 21 or upper member 22 of the fixed member 2 to which the sliding member 31 or the support member 32 is engaged may have an engaging surface that intersects with the axial direction on the horizontal plane of the bracing member 6. In the case where a "guide portion (safety groove) 23" described below is formed in the fixed member 2, this engaging surface is the inner peripheral surface of the "guide portion 23," but it may also be the surface of the space secured on the lower surface side of the upper member 22, or the edge of the space formed in the upper member 22.

[0024] The shapes of the slide member 31 and the support member 32 are not important except that the slide member 31 of the movable member 3 can freely move in and out under the upper member 22 of the fixed member 2, and when the slide member 31 is inserted under the upper member 22, the slide member 31 or the support member 32 can be engaged with the lower member 21 or the upper member 22 of the fixed member 2.

[0025] As described above, in order for the fixed member 2 to restrain the movement of the movable member 3 when the bracing member 6 attempts to move, such as by tipping over, the slide member 31 or the support member 32 may be engaged with the lower member 21 or the upper member 22 of the fixed member 2 when the slide member 31 of the movable member 3 is inserted under the upper member 22 of the fixed member 2. Therefore, since there is no need to anchor the fixed member 2 in the ground, such as by burying it in the ground, in order to restrain the movable member 3, the structure for preventing the bracing member 6 from tipping over, etc. is simplified.

[0026] Since there is no need to anchor the fixed member 2 to the ground, the work of separating the bracing member 6 from the restraint device 1 and the work of reconnecting it to the restraint device 1 are simplified, improving the efficiency of the work involved. Additionally, when separating (recovering) the bracing member 6 from the restraint device 1, the moving member 3 is generally detached from the fixed member 2 as shown in Fig. 5-(b), which avoids the impact on the wheels and body of the vehicle that would be caused by leaving the moving member 3 behind. "In principle" means that, depending on the length of the support material 32, there is no possibility that the bottom of the body will come into contact with the support material 32, and therefore it is not necessarily necessary to recover the moving member 3 together with the bracing member 6.

[0027] The sliding material 31 can be freely inserted under the upper material 22 of the fixed material 2 because, in addition to the space formed between the underside of the upper material 22 and the ground surface or the surface of the steel plate 9 as described above, a space is formed under the upper material 22 into which the support material 32 can enter.

[0028] "A space is formed between the lower surface of the upper member 22 and the ground surface or the like" or "a space is formed below the upper member 22" specifically means that, for example, a guide portion 23 that guides the entry and exit of the slide member 31 or the support member 32 of the movable member 3 is formed on the lower member 21 or the upper member 22 of the fixed member 2 (claim 2). The guide portion 23 is, for example, a guide groove as shown in Fig. 3. When the guide portion 23 is formed on the lower member 21, a space that allows the support member 32 to enter is formed on the upper member 22, and when the guide portion 23 is formed on the upper member 22 as shown in the figure, a space that allows the slide member 31 to enter is formed on the lower surface of the upper member 22.

[0029] In this case, a guide portion (guide groove) 23 is formed in the lower member 21 or the upper member 22 of the fixed member 2, so that the sliding member 31 can smoothly move in and out of the fixed member 2, and the operation of disconnecting and reconnecting the support member 6 from the restraint device 1 is made efficient.

[0030] In particular, as shown in Fig. 1, when the direction of movement of the movable member 3 into and out of the fixed member 2 is approximately perpendicular to the axial direction of the brace member 6 when projected onto a plane (claim 3), the direction of movement of the brace member 6, such as tipping over, is substantially perpendicular to the direction of movement of the movable member 3. Therefore, the force acting on the movable member 3 when the brace member 6 tries to move is unlikely to have a component in the direction of movement of the movable member 3, making it possible to effectively restrain the movement of the brace member 6. Effect of the Invention

[0031] When the slide material of the movable member, which is inserted freely in and out under the fixed member fixed to the ground or steel plate, is inserted under the fixed member, the slide material or the support material fixed on it is engaged with the fixed member in the axial direction of the bracing material to restrain the movement of the bracing material, so there is no need to fix the fixed member in the ground to restrain the movable member of the bracing material, and the structure for preventing the bracing material from falling over, etc. can be simplified.

[0032] As a result, the work of separating the brace from the restraint device having a fixed member and a movable member and the work of reconnecting it to the restraint device are simplified, improving the efficiency of the work. In principle, when separating (recovering) the brace from the restraint device, the movable member is detached from the fixed member, so it is possible to avoid the effects of leaving the movable member behind, such as damage to the wheels of the vehicle.

[Figure 6] 1(a) to 1(c) are perspective views showing examples of conventional methods for restraining a bracing member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Figures 1 to 3 show an example configuration of a restraint device 1 which comprises a fixed member 2 fixed to the ground or to a steel plate 9 laid on the ground, and a movable member 3 which can be inserted freely in and out of the fixed member 2 in one direction, etc., and which maintains a bracing member 6 connected to a temporary fence 8 shown in Figure 1, or a gate 7 which constitutes part of it and can be opened and closed, in an indirectly restrained state to the ground when the temporary fence 8 or the gate 6 is closed.

[0035] 2 and 3 show an example in which the lower member 21 of the fixing member 2 is fixed to the steel plate 9 by welding, but also show a case in which the fixing member 2 is fixed to the concrete pavement 10 or asphalt pavement, which corresponds to the ground, using anchors 5 instead of the steel plate 9. The fixing member 2 may also be fixed directly to the ground. Hereinafter, the concrete pavement 10 or asphalt pavement, including the ground, will be referred to as the concrete pavement 10, etc. Whether by welding or by anchors 5, the fixing member 2 is fixed to the steel plate 9, concrete pavement 10, etc. on-site.

[0036] As shown in Figure 1, the restraint device 1 is installed on a steel plate 9 laid from the inside of the construction area to the temporary fence 8, or to the outside of the area across the gate 7, or on a concrete pavement 10, etc., and mainly supports the lower end of a brace 6 which prevents the gate 7 from tipping over outside the area.

[0037] The bracing members 6 are installed between and connected to the support members 32 (described later) of the movable member 3 and the temporary enclosure 8, or the center or other intermediate portion in the opening and closing direction when the gate 7 is closed. The gate 7 has a structure that allows it to be opened and closed horizontally by expanding and contracting like a pantograph, for example. In this case, the gate 7 may be opened by separating both sides in the width direction of the opening and closing section, or it may be opened to one side in the width direction.

[0038] As shown in Fig. 2, the fixed member 2 has a lower member 21 that is fixed to the steel plate 9, concrete pavement 10, etc., and an upper member 22 that is fixed to the lower member 21 while floating above the surface of the steel plate 9, concrete pavement 10, etc. Hereinafter, the steel plate 9 or concrete pavement 10, etc. will be referred to as the steel plate 9, etc. The lower member 21 and upper member 22 may be integral.

[0039] As shown in Fig. 3, the movable member 3 has a slide member 31 that is inserted freely between the iron plate 9 etc. below the upper member 22 of the fixed member 2, and a support member 32 that is fixed on top of the slide member 31 and to which the lower end of the bracing member 6 is connected. In Fig. 3, the dashed line overlapping the upper member 22 indicates the slide member 31 and the support member 32 when inserted into the back side of the fixed member 2.

[0040] When the slide member 31 of the movable member 3 is inserted under the upper member 22 of the fixed member 2, the slide member 31 or the support member 32 is in a state in which it can be horizontally engaged with the lower member 21 or the upper member 22 of the fixed member 2. The "horizontal direction" refers to the horizontal direction along the axial direction of the brace member 6 when the brace member 6 is projected onto a horizontal plane. The "direction along the axial direction of the brace member 6" refers to the axial direction of the brace member 6 on the horizontal plane, or a direction close to that direction.

[0041] The shapes of the lower member 21 and the upper member 22 are not important as long as the sliding member 31 can freely move in and out from under the upper member 22 and the sliding member 31 or the support member 32 can engage with the lower member 21 or the upper member 22 when the sliding member 31 is inserted under the upper member 22. However, in the drawing, plates or flat bars are used for the lower member 21 and the upper member 22 so that the wheels will not be affected even if they run over the fixed member 2 when a vehicle runs over the fixed member 2 that is left on the iron plate 9 or the like as shown in Figure 5-(b) after the bracing member 6 is collected together with the movable member 3 and the gate 7 is opened.

[0042] However, the restraint device 1 only needs to be partially positioned on an extension line of the middle part in the opening and closing direction of the gate 7 when it is closed, as shown in Fig. 1. Furthermore, when there is one bracing member 6 connected to the support member 32 as shown in Fig. 3, since the height of the support member 32 is small, even if the movable member 3 (support member 32) is left behind when the support member 6 is removed, there is little possibility that the underside of the vehicle will be damaged.

[0043] 2 and 3, the guide portion 23 that guides the entry and exit of the support member 32 of the movable member 3 is formed on the upper member 22 of the fixed member 2, but the guide portion 23 may also be formed on the lower member 21. In the illustrated example in which the guide portion 23 is formed on the upper member 22, the lower member 21 may have a shape that does not impede the entry and exit of the movable member 3. In the drawings, the lower member 21 is formed in a flat shape that is positioned so as not to interfere with the entry and exit area so as not to impede the entry and exit of the slide member 31 of the movable member 3.

[0044] Specifically, as shown in Fig. 3, the lower member 21 is made up of three parts: side parts 21a, 21a located on both sides in the direction of entry and exit of the movable member 3 (direction of the guide part 23), and a rear part 21b located on the rear side in the direction of entry and exit, but the configuration of the lower member 21 is arbitrary. In the example of Fig. 3, the upper member 22 has an area spanning all of the components of the side parts 21a, 21a and the rear part 21b. The lower member 21 and the upper member 22 are mainly joined to each other in a factory by welding or the like.

[0045] When the lower member 21 is composed of three parts, the side parts 21a, 21a and the rear part 21b, each part can be separated from the other to form a water drainage groove 24 that also serves to drain dirt between the side parts 21a, 21a and the rear part 21b as shown in Fig. 3, making it possible to use water to drain dirt from the space below the upper member 22. By being able to drain dirt, it is possible to prevent a situation in which the slide member 31 cannot be inserted below the upper member 22 due to dirt accumulating.

[0046] When the guide portion 23 is formed on the upper member 22, it is sufficient that the upper member 22, while fixed to the lower member 21, has the role of restraining the lifting of the slide member 31 of the movable member 3 inserted between the upper member 22 and the lower member 21. The entire guide portion 23 serves to guide the entry and exit of the support member 32, and the inner peripheral surface of the guide portion 23 serves to lock the support member 32 in the horizontal direction when the bracing member 6 tries to move.

[0047] Furthermore, when the guide portion 23 is formed in the upper member 22, the lower member 21 only needs to have the role of serving as a platform for supporting the upper member 22 and the role of being able to receive the slide member 31 of the movable member 3, and the planar shape of the lower member 21 is arbitrary. When the guide portion 23 is formed in the lower member 21, the portion of the lower member 21 that can receive the slide member 31 also serves as the guide portion 23. In that case, the upper member 22 only needs to have an opening through which the support member 32 can freely move in and out.

[0048] For these reasons, in the drawings, a plate that overlaps and is fixed to the upper surface of the lower member 21 is used as the upper member 22 as described above. The upper member 22 is joined to the lower member 21 by welding, bolts, etc., with a distance between the upper member 22 and the surface of the iron plate 9 or the like that allows the sliding member 31 of the moving member 3 to fit in. The "distance that the sliding member 31 can fit in" is ensured by the thickness of the lower member 21.

[0049] The slide member 31 of the moving member 3 is in the form of a plate that is inserted into the space between the surface of the ground or the surface of the steel plate 9 and the upper member 22. The support member 32 is in the form of a rod or tube that can be inserted into the guide portion 23 of the upper member 22 and has a thickness that allows a gripping device 4 such as a free clamp that grips the bracing member 6 to be connected. In the drawing, a plate is used for the slide member 31 and a steel pipe is used for the support member 32, but shaped steel can also be used for the support member 32. When the support member 32 is inserted into the guide portion 23, it can be engaged with the inner peripheral surface of the guide portion 23 as described above. One gripping portion 41 of the gripping device 4 is connected to the support member 32, and the lower end of the bracing member 6 is connected to the other gripping portion 42.

[0050] In the drawings, the direction in which the movable member 3 moves in and out of the fixed member 2 is parallel to the opening and closing direction of the gate 7 or the length direction of the rail as shown in Fig. 1, but this is not necessarily required. The "direction in which the movable member 3 moves in and out" is the length direction of the "guide section 23" when it is formed in one direction.

[0051] However, when the gate 7 is closed, the sliding member 31 of the movable member 3 is moved towards the fixed member 2, and the support member 32 is inserted into the one-way guide section 23, the stability when the brace member 6 tries to move, i.e., the restraining effect of the restraining device 1, is highest when the axial direction on the plane of the brace member 6 is perpendicular to the length direction of the guide section 23. This is because the force acting on the support member 32 when the brace member 6 tries to move is unlikely to have a component in the length direction of the guide section 23. "Axial direction on the plane" refers to the axial direction when the brace member 6 is projected onto the surface of the steel plate 9, etc. "One-way guide section 23" refers to the innermost section when the guide section 23 is formed in multiple directions, such as bent or curved.

[0052] The lower end of the bracing material 6 is basically connected to a holding device 4 such as a clamp that is connected to the support material 32 with the support material 32 inserted into the back side of the guide section 23, but the bracing material 6 may also be connected to the support material 32 before the support material 32 is inserted into the guide section 23. The upper end of the bracing material 6 is connected by a holding device 4 such as a catch clamp to a vertical member 72 of a panel 71 that constitutes the gate 7 and is located, for example, in the center of the opening / closing section of the gate 7 when it is in the closed state.

[0053] Figure 4 shows an example in which two braces 6, 6 of different lengths are connected to a support member 32 using two holding devices 4, 4 that are connected to the support member 32 at an axial distance apart, as shown in Figure 5-(a). In the cases of Figures 4 and 5, the two braces 6, 6 are connected to the support member 32 with different inclination angles, but if the two braces 6, 6 are equal in length, they are installed in parallel. Three or more braces 6 may also be installed.

[0054] Fig. 5-(b) shows how the bracing members 6 are retrieved from the support members 32, the movable members 3 are removed from the fixed members 2 and retrieved, the gate 7 is opened, and then vehicles pass over the iron plates 9 and the like from within the premises. Even if the wheels run over the fixed members 2, if the fixed members 2 are made of plates, the impact of damaging the wheels and the like is small. [Explanation of symbols]
