Description

 Temporary stent  

The present invention relates to a temporary support for use in supporting construction objects in various construction sites, construction sites, and the like. It belongs to the technical field of constructing a temporary bracket by connecting a plurality of pipes.

For example, in various construction sites, construction sites, and the like, various operations are performed in a state where the construction is supported by a temporary support. For example, a temporary bracket which is integrally joined by a joint member and is called a square pillar, a temporary bracket made of a thick steel pipe, and the like are all temporary brackets which are generally used. Using them, it is possible to support a building having a certain weight.

The above-mentioned square pillars are four pipes which are joined by welding and cannot be separated, so the weight of each pillar is heavier. In order to increase the load allowed by the temporary bracket composed of steel pipes, the temporary brackets are generally thick and the wall thickness is also thick, so that the weight of each pillar is heavier. Therefore, in the case of using a temporary bracket composed of a conventional square pillar or a steel pipe, the operator cannot carry the temporary bracket by manual work, and the temporary bracket can only be transported by a crane or the like. Therefore, conventionally, it has not been possible to carry a conventional square pillar, a steel pipe, or the like into a closed chamber such as a pit, a pipe, or a tank in which it is difficult to install a crane or the like.

For example, as disclosed in Patent Documents 1 to 3, it has been known that a plurality of pillars are connected by a detachable coupling to increase the load allowed for each temporary bracket. The pillar disclosed in Patent Document 1 is provided with a connecting metal member for a temporary bracket for connecting a horizontal frame member or a diagonal member. By using the temporary metal fitting for the temporary bracket, the temporary bracket can be reinforced with the cross member and the oblique material without colliding with the horizontal connecting member or the like. The temporary holder disclosed in Patent Document 2 is constructed such that a horizontal member connecting protruding portion is provided on a pillar that is vertically disposed at a predetermined interval in the horizontal direction, and a hole is formed in the horizontal material connecting protruding portion. The horizontal member with the wedge mechanism is joined to the hole in the protruding portion for the horizontal material connection, and the plurality of pillars are connected to each other, thereby constructing the temporary bracket. The temporary bracket disclosed in Patent Document 3 is constructed by previously arranging a metal bracket having a tapered hole on a pillar, joining a horizontal member to a wedge-shaped hole, and joining a plurality of pillars, thereby constructing a temporary bracket. .

According to the temporary bracket disclosed in Patent Document 1 to Patent Document 3, a plurality of pillars are connected by a detachable coupling. Therefore, it is easy to disassemble the temporary bracket so that the pillar can be carried in units of one pillar. The weight of one of the pillars disclosed in Patent Document 1 to Patent Document 3 is generally so heavy that the human body can be transported. Therefore, the operator can carry the pillar to the underground pit and the sealed room by manpower, and the convenience is improved. By changing the number of pillars used in combination, it is easy to set the load allowed by the temporary bracket at each site, which is also an advantage. It is also possible to freely arrange the pillars according to the shape of the supported building. In other words, there are various advantages in constructing a temporary bracket by connecting a plurality of pillars with a detachable link.

Although the temporary bracket constructed by connecting a plurality of pillars with a detachable link has many advantages as described above, the following problems exist. That is, the upper end portion of the pillar is a portion to which the load of the structure directly acts, and in order to support the structure in a stable state, it is necessary to appropriately maintain the relative positional relationship between the upper end portions of the plurality of pillars constituting the temporary bracket. The lower end portion of the pillar is a portion supported by a jack or the like, and in order to support the structure in a stable state, it is also necessary to appropriately maintain the relative positional relationship between the lower end portions. However, the fasteners disclosed in Patent Document 1 to Patent Document 3 are used to connect the intermediate portions in the longitudinal direction of the strut, and the upper end portions and the lower end portions of the strut are not connected to each other.

The present invention has been accomplished in view of the above problems. In the case where the temporary support is constructed by connecting a plurality of pillars with a detachable link, the relative positional relationship between the ends of the plurality of pillars in the vertical direction can be appropriately ensured, and the structure can be supported in a stable state. .

In order to achieve the above object, the temporary support for supporting the structure from below includes: a plurality of pillars, an intermediate joint member, and an end joint member, wherein the plurality of pillars respectively extend in the up and down direction, and the plurality of pillars are spaced apart from each other in the horizontal direction. The intermediate portion connecting member is detachably attached to an intermediate portion of the pillar in the vertical direction, and the intermediate portion connecting member connects the intermediate portions of the pillar, and the end connecting member connects one end portion of the pillar in the vertical direction. Connected together.

According to this configuration, the intermediate portion coupling member can be attached to the pillar and can be detached from the pillar. Therefore, the temporary bracket can be easily split into one by removing the intermediate portion connecting member from the pillar. The pillars of the roots. Since one of the pillars can be transported by human power, for example, the pillar can be transported to the underground pit or the sealed room by the strength of the operator. By changing the number of pillars to be combined, it is easy to set the load allowed by the temporary bracket at each work site. It is also possible to freely arrange the pillars according to the shape of the supported building.

When the temporary bracket is constructed, the intermediate portion of the plurality of pillars is connected to each other in the vertical direction by the intermediate portion connecting member, and the one end portion of the plurality of pillars is connected to each other by the end connecting member. By connecting the one ends of the plurality of pillars by the end joints, the relative positional relationship between the one ends of the pillars can be appropriately maintained. Therefore, the building can be supported in a stable state.

The end connecting member may include: a substrate extending in a horizontal direction; and a plurality of protruding cylindrical portions fixed to the substrate and protruding upward from the substrate, wherein the pillar top is in a protruding direction of the protruding tubular portion On one end.

According to this configuration, the end of the protruding tubular portion can be brought into contact with the pillar by the pillar top on the end portion of the protruding tubular portion, thereby reliably supporting the building.

The struts may be formed of a pipe material whose one end portion is open in the vertical direction, and the end portion coupling member is provided with an insertion cylinder portion that is inserted into the struts from the opening of the one end portion, the insertion The tubular portion protrudes from the protruding cylindrical portion toward the center line direction of the protruding tubular portion.

According to this configuration, by inserting the insertion tube portion into the column from the opening of the one end portion of the column, the protruding tube portion of the end piece and the column are less likely to be displaced in the radial direction, and the end piece can be used. The one end of the pillar is reliably connected to each other.

The configuration may be such that the end connecting member is provided with a reinforcing member fixed to the outer surface of the substrate and the protruding tubular portion.

According to this configuration, since the substrate and the protruding tubular portion are coupled by the reinforcing member, it is possible to suppress the oblique deformation or the like of the protruding tubular portion. Therefore, the building can be supported in a more stable state.

The configuration may be such that the reinforcing member is fixed to the outer surface of the plurality of protruding cylindrical portions.

According to this configuration, the plurality of protruding tubular portions are connected by the reinforcing member. Therefore, the relative positional relationship between the plurality of protruding cylindrical portions can be appropriately maintained.

According to the present invention, since the intermediate portions of the pillars are connected by the detachable intermediate portion connecting members, it is easy to separate the temporary brackets into one pillars, and it is possible to carry them by hand. Since the end portions of the pillars are connected to each other in the vertical direction by the end joints, the relative positional relationship between the one ends of the pillars can be appropriately maintained, and the building can be supported in a stable state.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It is to be noted that the following preferred embodiments are merely illustrative of the invention and are not intended to limit the scope of the invention.

(First embodiment)

1 is a side view showing a state in which a monument 100 is supported by a temporary bracket 1 of a first embodiment of the present invention. The temporary bracket 1 is used when supporting various structures 100, for example, at various construction sites, construction sites, and the like. The structure 100 includes, for example, a concrete frame used when constructing a concrete floor or a girders. The concrete frame can be supported by the temporary support 1 from the pouring of the concrete to the solidification of the concrete. The monument 100 may also be, for example, a bridge or the like.

A plurality of temporary brackets 1 are constructed to support one monument 100, and these temporary brackets 1 are joined together. First, each temporary bracket 1 will be described. Each of the temporary supports 1 is constructed by connecting and connecting four pillars 10, and each of the four pillars 10 extends in the vertical direction, and the four pillars 10 are spaced apart from each other in the horizontal direction. Assume. For example, it is also possible to use each of the temporary brackets 1 including the four pillars 10 as shown in the top view of Fig. 2, that is, the temporary brackets 1 are arranged in two rows and connected to each other to have a circular arc shape. In this case, the shape of the monument 100 is approximately circular. Further, the temporary holders 1 can be used in a straight line and connected to each other, and can be used alone. The number and arrangement of the temporary supports 1 can be arbitrarily set according to the shape, size, and weight of the structure 1.

Also shown in FIG. 3, the temporary bracket 1 includes an intermediate portion coupling member 20, a lower side end coupling member 30, an upper side end coupling member 40, and a base 50 in addition to the four pillars 10. The intermediate portion coupling 20 is attached to the intermediate portion in the vertical direction of the adjacent pillars 10 on which the temporary bracket 1 is constructed, and is detachable, and the intermediate portions of the pillars 10 are connected to each other. The lower end link 30 connects the lower end portions of all the pillars 10 constituting the temporary holder 1. The upper end link 40 connects the upper end portions of all the pillars 10 constituting the temporary bracket 1 to each other. It should be noted that the base 50 can be omitted.

The four pillars 10 are all the same pillars. In this embodiment, as shown in FIG. 2, the four pillars 10 are arranged at substantially equal intervals to each other, and have a quadrangular shape in plan view. However, the present invention is not limited thereto, and the pillars 10 may be arranged in a polygonal shape such as a pentagon or a hexagon in a plan view, and the temporary bracket 1 may be constructed by three pillars 10 or two pillars 10. The number of the pillars 10 for constituting one temporary bracket 1 can be arbitrarily set. Adjacent temporary supports 1 are joined by horizontal reinforcing members 60 (shown by phantom lines in Fig. 2).

As shown enlarged in FIG. 4, the strut 10 has a metal pipe 11 having a circular cross section and a joint portion 12 composed of a metal plate. The pipe material 11 can be configured, for example, by a steel pipe or the like, and the pipe material 11 is arranged to extend in the vertical direction, and the length of the pipe material 11 is set so as to match the height of the temporary bracket 1 to be constructed. Both ends of the pipe 11 in the vertical direction are opened. A cylindrical lower small diameter portion 13 is formed in a lower portion of the pipe member 11. The outer diameter of the lower small diameter portion 13 is smaller than the outer diameter of the intermediate portion of the pipe 11 in the vertical direction. By forming the lower small-diameter portion 13, a lower step portion 14 is formed at a lower portion of the outer peripheral surface of the pipe member 11. A cylindrical upper small-diameter portion 15 is formed in an upper portion of the pipe member 11, and an outer diameter of the upper small-diameter portion 15 is smaller than an outer diameter of the intermediate portion of the pipe 11 in the vertical direction. By forming the upper small-diameter portion 15, an upper step portion 16 is formed on the upper portion of the outer peripheral surface of the pipe 11. The lower small diameter portion 13 and the upper small diameter portion 15 have the same cross-sectional shape, and the length, the outer diameter, and the inner diameter are equal. The length of the pillar 10 is not particularly limited, and the length thereof can be made to meet the requirements of the construction site. It is also possible to connect the plurality of pillars 10 up and down, and the pillars 10 can be attached and detached.

The connecting portion 12 is a portion to which the intermediate portion connecting member 20 is coupled, and a plurality of connecting portions 12 are provided at respective portions of the upper side, the lower side, and the intermediate portion of the vertical direction of the pipe member 11. As shown in FIG. 5, the connection part 12 protrudes radially from the outer peripheral surface of the pipe material 11 in four directions. That is, the four joint portions 12 are arranged at the same height of the pipe 11. An engagement hole 12a is formed inside the coupling portion 12. The engagement hole 12a is opened toward both the upper and lower sides of the joint portion 12. The cross section of the engaging hole 12a in the horizontal direction is approximately rectangular.

As shown in Fig. 6, the intermediate portion coupling 20 has a rod member 21 extending in the horizontal direction and a wedge-shaped engaging projection portion 22 projecting downward from both end portions of the rod member 21. The engagement protruding portion 22 is joined to the coupling portion 12 in a state of being inserted into the engagement hole 12a of the support 10 from above. Projecting portions 23 projecting upward are formed at both end portions of the rod member 21. The length of the intermediate portion coupling 20 in the horizontal direction is set to correspond to the pitch of the pillars 10. The pitch between the adjacent pillars 10 is set to a predetermined pitch in accordance with the length of the rod 21 of the intermediate portion coupling 20 in the horizontal direction. The spacing between the pillars 10 can be set according to the weight of the monument 100. For example, preferably, the heavier the monument 100, the smaller the spacing between the pillars 10. For example, the pitch between the pillars 10 can be set to 150 mm to 250 mm. In this embodiment, the pitch between the pillars 10 is set to 200 mm.

As shown in FIGS. 1 and 3, the base 50 is used to adjust the height of the four pillars 10, which is constructed in a conventional configuration. That is, the base 50 includes a base 51, a screw shaft 52 extending upward from the base 51, and a movable portion 53 screwed to the screw shaft 52. The base 51 is disposed on the support member 200. The movable portion 53 is rotated in a state of being screwed to the screw shaft 52, that is, the height of the movable portion 53 can be changed. As shown in FIG. 3, the upper side of the screw shaft 52 protrudes upward from the center portion of the movable portion 53. The upper surface of the movable portion 53 extends approximately horizontally, and as will be described later, the lower end joint 30 is placed and fixed on the upper surface of the movable portion 53.

As shown in FIGS. 7 and 8, the lower end connecting member 30 has a substrate 31 extending in the horizontal direction, four protruding cylindrical portions 32 fixed to the substrate 31 and protruding upward from the substrate 31, and reinforcing members. 34. The substrate 31 is a portion fixed to the base 50. As shown in Fig. 8, the shape of the substrate 31 is approximately quadrangular in plan view. A through hole 31a is formed in a central portion of the substrate 31, and an upper side of the screw shaft 52 of the base 50 passes through the through hole 31a. The substrate 31 is fastened to the movable portion 53 of the base 50 by a connecting member (not shown), and a plurality of insertion holes 31b penetrating the substrate 31 in the thickness direction are formed in the peripheral portion of the substrate 31, and the fastening member is inserted into the insertion hole. Within 31b.

The four protruding cylinder portions 32 are arranged to coincide with the arrangement positions of the four pillars 10 constituting the temporary bracket 1. These protruding cylinders 32 are all the same. The outer diameter of each of the protruding tubular portions 32 is substantially equal to the outer diameter of the portion constituting the intermediate portion in the vertical direction of the strut 10, that is, substantially equal to the outer diameter of the portion other than the lower small-diameter portion 13 and the upper small-diameter portion 15 of the strut 10. . The inner diameter of each of the protruding tubular portions 32 is ensured to be able to insert the lower small-diameter portion 13 of the strut 10 into the protruding tubular portion 32. Specifically, the inner diameter of each of the protruding tubular portions 32 is set to be substantially equal to the outer diameter of the lower small-diameter portion 13 or slightly larger than the outer diameter of the lower small-diameter portion 13 . By inserting the lower small-diameter portion 13 of each of the pillars 10 into each of the protruding tubular portions 32, the lower end portions of the pillars 10 are connected to each other, and the relative positional relationship between the lower end portions of the pillars 10 is appropriately maintained. By inserting the lower small-diameter portion 13 into the protruding tubular portion 32, the lower small-diameter portion 13 hardly displaces in the radial direction with respect to the protruding tubular portion 32. In a state in which the lower small diameter portion 13 is inserted into the protruding tubular portion 32, the lower step portion 14 is placed on the upper end portion of the protruding tubular portion 32.

The reinforcing member 34 is provided with four. Each of the reinforcing members 34 is constituted by a plate member fixed to the upper surface of the substrate 31 and the outer surface of the protruding cylindrical portion 32, and each reinforcing member 34 is arranged such that the upper surface of the substrate 31 protrudes upward. Both end portions of the reinforcing member 34 are fixed to the outer surface of the adjacent projecting cylindrical portion 32, and the two projecting tubular portions 32 are joined by one reinforcing member 34.

The structure of the upper end connecting member 40 is the same as that of the lower end connecting member 30, and the lower end connecting member 30 is turned upside down. The lower end connecting member 30 can be used as the upper end connecting member 40. . In other words, the upper end link 40 has a substrate 41 extending in the horizontal direction, four protruding tubular portions 42 fixed to the substrate 41 and protruding downward from the substrate 41, and a reinforcing member 44. The upper small diameter portion 15 of the strut 10 is inserted into the protruding tubular portion 42. By inserting the upper small-diameter portion 15 of each of the pillars 10 into each of the protruding tubular portions 42, the upper end portions of the pillars 10 are connected to each other, and the relative positional relationship between the upper end portions of the pillars 10 can be appropriately ensured.

It should be noted that the substrate 41 of the upper end link 40 directly supports the structure 100, or the structure 100 is supported while other components are located between the substrate 41 and the structure 100. It is also possible to arrange a base (not shown) on the upper side of the substrate 41.

As shown in FIG. 3, the horizontal reinforcing member 60 has a rod member 61 extending in the horizontal direction and a wedge-shaped engaging projection portion 62 projecting downward from both end portions of the rod member 61. The engagement projection 62 is engaged with the coupling portion 12 in a state of being inserted into the engagement hole 12a of the support 10 from above. A protruding portion 63 that protrudes upward is formed at both end portions of the rod 61.

The length of the horizontal reinforcing member 60 in the horizontal direction is set so as to correspond to the interval between the adjacent temporary holders 1. The pitch between the adjacent temporary brackets 1 is set to a predetermined pitch in accordance with the length of the rod 61 of the horizontal reinforcing member 60 in the horizontal direction. The spacing between the temporary supports 1 can be set according to the weight of the building 100. The plurality of temporary brackets 1 are joined by the horizontal reinforcing members 60 to be integrated.

Next, it is explained how the temporary bracket 1 is constructed as described above. As described above, the materials constituting one temporary holder 1 are four pillars 10, a plurality of intermediate portion coupling members 20, a lower end portion coupling member 30, an upper end portion coupling member 40, and a base 50. The intermediate portion coupling member 20 is joined to the pillar 10 only by the wedge-shaped engaging projection 22, and is not joined to the pillar 10 by welding or the like, so that the intermediate portion coupling member 20 can be easily attached to the pillar 10 or the intermediate portion coupling member can be easily attached. 20 is detached from the pillar 10. Further, since the lower small-diameter portion 13 of each of the pillars 10 is inserted only into each of the protruding tubular portions 32 without being welded or the like, it is easy to attach the lower-end end connecting member 30 to the pillar 10 or to the lower end portion. The link 30 is detached from the post 10. The same applies to the upper end link 40.

Therefore, it is easy to construct the temporary bracket 1 at the construction site by easily disassembling the temporary bracket 1. Since the pillars 10 are in a non-connected state in a state in which the temporary bracket 1 has been disassembled, the pillars 10 can be transported one by one. In other words, since the weight of one of the pillars 10 can be carried by a human being, the operator can carry the pillar 10 to the underground pit or the sealed room by human power.

When the temporary bracket 1 is constructed, the intermediate portions of the four pillars 10 are connected to each other in the vertical direction by the intermediate portion coupling 20, and the lower end portions of the four pillars 10 are connected to each other by the lower end connector 30. The end link 40 connects the upper ends of the four pillars 10 together. By connecting the lower end portions of the pillars 10 and the upper end portions, the relative positional relationship between the lower end portions of the pillars 10 can be appropriately maintained, and the relative positional relationship between the upper end portions can be appropriately maintained. . Therefore, the monument 100 can be supported in a stable state.

As in the first modification of the first embodiment shown in FIGS. 9 and 10, four insertion tube portions 33 can be provided in the lower end link member 30, and the insertion tube portions 33 are all from the lower end portion (one end in the up and down direction). The opening of the portion is inserted into each of the pillars 10. In the first modification, the lower small diameter portion and the upper small diameter portion 15 of the support 10 are not formed, and are not shown.

In the first modification, the lower portion of the insertion tube portion 33 of the lower end connector 30 is inserted into the protruding tubular portion 32, and is fixed by welding or the like. The outer diameter of the insertion tube portion 33 is such that the insertion tube portion 33 can be inserted into the lower portion of the column 10. Specifically, the outer diameter of the insertion tubular portion 33 is set to be substantially equal to the inner diameter of the lower portion of the strut 10 or slightly smaller than the inner diameter of the lower portion of the strut 10 . The upper side of the insertion tubular portion 33 protrudes from the upper end portion of the protruding tubular portion 32 toward the center line direction (upward) of the protruding tubular portion. A portion of the insertion tubular portion 33 that protrudes from the protruding tubular portion 32 is inserted into the strut 10. The lower end portion of the pillar 10 is placed at one end portion (upper end portion) of the protruding direction of the protruding tubular portion 32. Therefore, the height of the pillar 10 is determined, and the weight of the monument 100 mainly acts on the protruding cylinder portion 32 from above. By inserting the insertion cylinder portion 33 into the strut 10, the lower end portion of the strut 10 is almost no longer displaced in the radial direction with respect to the protruding cylinder portion 32. It should be noted that the upper end link 40 can also have the same structure. It is also possible to make only the configuration of the lower end link 30 as shown in the first modification, or only the structure of the upper end link 40 as shown in the first modification.

11 to 15 are Modifications 2 of the first embodiment. In Modification 2, as shown in FIG. 11, when viewed from the front, the lower end portion of the temporary holder 1 disposed on the right side is located below the lower end portion of the temporary holder 1 disposed on the left side. In this case, the length of the pillar 10 of the temporary bracket 1 on the right side is made longer than the length of the pillar 10 which constructs the temporary bracket 1 on the left side. Further, the lower side of the pillar 10 of the temporary bracket 1 on the right side and the lower side of the pillar 10 of the temporary bracket 1 on the left side are connected by the horizontal reinforcing member 70. As shown in FIGS. 12 to 15, the horizontal reinforcing member 70 has a first pipe member 71, a second pipe member 72, and a third pipe member 73. The first pipe 71 is coupled to the first end member 74 via the first angle adjusting portion 76. The second pipe member 72 is coupled to the second end member 75 via the second angle adjusting portion 77. One of the ends of the third pipe 73 is inserted from one side of the first pipe 71 opposite to the first end member 74, and the other end of the two ends is inserted from the opposite side of the second pipe 72 from the second end member 75. . The first pipe member 71 and the second pipe member 72 are coupled by the third pipe member 73. In this connected state, the distance between the first pipe member 71 and the second pipe member 72 can be adjusted. That is, the third pipe 73 is fixed to the first pipe 71 in a state of being inserted into the first pipe 71, and on the other hand, the third pipe 73 can be opposed to the second in a state of being inserted into the second pipe 72. The tube 72 slides in the direction of the center line. As shown in FIG. 14, if the locking bolt 80 provided on the second pipe 72 is tightened, the locking bolt 80 will be placed on the third pipe 73 to prevent the third pipe 73 and the second pipe 72 from being opposed. mobile. 12 and 14 show a state in which the distance between the first pipe 71 and the second pipe 72 is increased; and FIG. 13 and FIG. 15 show a state in which the distance between the first pipe 71 and the second pipe 72 is reduced.

The first end member 74 is provided with a wedge-shaped engagement projection 78 that protrudes downward.
