Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support applied to slab formwork of concrete buildings, diagonal support for construction, mountain retaining support for civil engineering, support for trees and fruit trees, etc. .

[0002]

2. Description of the Related Art Generally, when forming a slab of a concrete building, for example, a plurality of supports are used as means for supporting a slab form. That is, in forming the slab, first, a plurality of supports are arranged at predetermined positions via the steady pipes. After the height of the upper end of each support is adjusted, a square pipe (end-wide angle) that is large is provided at each upper end. A round pipe, which is a joist, is assembled on the square pipe orthogonally thereto, and a veneer is arranged on the round pipe to assemble a form (slab frame) on the upper end of each support. Next, the slab is formed by driving concrete according to the formwork. Said supports are used to hold the formwork at the correct level and to support the weight of the poured concrete and play a very important role in the formation of the slab.

A typical example of the conventional support is shown in FIG.
And FIG. 27. The support 200 includes a support pipe 204 provided with a base 202 at a lower end, a support ring 206, an insertion pipe 210 provided with a receiving plate 208 at an upper end, and a support pin 212. A male screw 214 is formed on the upper end of the support pipe 204. In the male screw portion of the support pipe 204 where the male screw 214 is formed, a pair of elongated holes 216 penetrating from one side of the outer peripheral surface to the other and extending in the axial direction is formed.
In the drawing, only one of the long hole pairs 216 is shown. A female screw (not shown) is formed on an inner peripheral portion of the support ring 206, and a rotation operation handle 218 is mounted on an outer peripheral portion. The rotation operation handle 218 is in a horizontal position (FIG. 26).
(A solid line position) and a vertical position (a two-dot chain line position in FIG. 26). The support ring 206 is axially movable by being engaged with the male screw 214 of the support pipe 204 via the female screw. The support pin 212 is detachably connected to an outer peripheral portion of the support ring 206 by a chain 220. That is, one end of the chain 220 is connected to the head of the support pin 212,
The other end is hooked on a screw 207 provided on the outer periphery of the support ring 206.

The insertion pipe 210 is a support pipe 204.
A plurality of pairs of pin holes 222 which are inserted movably in the axial direction and penetrate from one of the outer peripheral surfaces to the other are formed at intervals in the axial direction. In the figure, only one of the pin hole pairs 222 is shown. The long hole pair 21
The width of 6 is larger than the diameter of the pin hole pair 222. The support pin 212 has a pair of elongated holes 216 and a pair of pin holes 22.
The diameter is defined so that it can be freely inserted into 2. In a state where the insertion pipe 210 is inserted into the support pipe 204, when the support pin 212 is inserted into one of the pin hole pairs 222 of the insertion pipe 210 through the long hole pair 216 of the support pipe 204, both ends thereof are long. It has a length that protrudes radially outward of the support pipe 204 from the hole pair 216. Furthermore, in the same state,
The insertion pipe 210 is configured so that both ends of the support pin 212 are mounted on the upper end surface of the support ring 206 so that the height of the insertion pipe 210 can be freely adjusted with respect to the support pipe 204.

For example, as a means for supporting a slab formwork of a concrete building, the support 200 is used as follows. Although a plurality of supports 200 are used, one support 200 will be described here for convenience of explanation. The support pipe 204 is mounted on a mounting surface such as a floor (not shown) via the base 202. Support pipe 204
The support ring 206 is previously engaged with the male screw 214 of the. The insertion pipe 210 is inserted from the upper end of the support pipe 204. At a position where the height of the receiving plate 208 of the insertion pipe 210 from the floor is roughly adjusted to a predetermined height, one circumferential position of the pin hole pair 222 is set to the long hole pair 216 of the support pipe 204. Align (align) with. Next, the support pin 212 is inserted into the pair of long holes 216 and the pair of pin holes 222, and both ends thereof are inserted into the pair of long holes 216.
Is positioned so as to project radially outward from the support pipe 204. When the insertion pipe 210 is lowered in this state,
Both ends of the support pin 212 are placed on the upper end surface of the support ring 206. As a result, the insertion pipe 210 is stably supported by the support pipe 204 via the support pin 212 and the support ring 206 with the lower part of the insertion pipe 210 inserted into the support pipe 204. The other end of the chain 220 is detached from the screw 207 of the support ring 206, and is wrapped around the insertion pipe 210 above the support pin 212 (see FIG. 27). By operating the rotation operation handle 218, the support ring 206 is supported by the support pipe 20.
4 is moved in the axial direction (vertical direction). By this movement, the support pin 212 is moved along the pair of long holes 216, so that the insertion pipe 210 and the receiving plate 208 are also moved at the same time. Thereby, the height of the insertion pipe 210, that is, the height of the receiving plate 208 is adjusted to a predetermined height. A slab formwork is attached to the upper part of the receiving plate 208, and concrete is poured (neither is shown).

The support 200 must be removed from the slab formwork after a predetermined period of time has elapsed since the concrete was poured. By operating the rotation operation handle 218, the insertion pipe 210 is moved downward. As a result, the receiving plate 2
08 is separated downward from the slab formwork. After removing the slab form, the support pin 212 is pulled out from the pin hole pair 222 and the long hole pair 216 while the insertion pipe 210 is slightly raised with respect to the support pipe 204. Plug-in pipe 2
By lowering 10 as it is, it is inserted deeply into the support pipe 204 to be in the housed state.

[0007]

The conventional support 200 constructed and used as described above has the following problems to be solved. (1) The support 200 is configured by a two-stage type including a support pipe 204 and an insertion pipe 210 inserted into the support pipe 204. In this configuration, the support pipe 204 and the insertion pipe 2
It is necessary to increase the axial length of each of the ten. However, such a configuration causes a problem in the stability of the entire support 200, and therefore the practical height limit thereof is relatively low. That is, with the support 200, it is practically difficult to stably support a load at a higher position. (2) When concrete is driven into the slab formwork, a heavy load due to concrete acts on the support 200. This heavy load acts on the upper end surface of the support ring 206 via both ends of the receiving plate 208, the insertion pipe 210, and the support pin 212. In this way, in order to move the insertion pipe 210 downward in the state where the heavy load due to the heavy load is applied to the support 200, the support ring 206 must be rotated. However, as described above, the support ring 20
Since a heavy load is directly applied to the upper end surface of the support ring 212 via both ends of the support pin 212, it is necessary to overcome a large frictional force in order to rotate the support ring 206.
Since one rotation operation handle 218 is attached to the outer periphery of the support ring 206, the support ring 20
In order to rotate 6, the rotation operation handle 218 must be turned by one hand, and actually the support ring 20
It is often difficult to rotate 6 by hand. In this case, a method of forcibly rotating the rotation operation handle 218 by hitting it with a hammer or the like is often used. As a result, problems such as damage or breakage of the rotation operation handle 218 and damages to the threaded portions of the support pipe 204 and the support ring 206 will occur. (3) The support pin 212 is connected to the outer periphery of the support ring 206 by the chain 220. This is the support pin 21
However, the presence of the relatively long chain 220 impairs workability when the support pin 212 is used or not used. When the support pin 212 is used, that is, when the height is adjusted, the support pin 212 is inserted into the pin hole pair 222 of the insertion pipe 210. Then, in order not to hinder the rotation operation of the support ring 206, the chain 22
One end of 0 is removed from the screw 207 of the support ring 206, and the insertion pipe 210 located above the support pin 212.
It is necessary to wrap it around. When the support ring 206 is rotated in this state, the chain 220 wound around may be unraveled by the movement of the support pin 212.
When the support pin 212 is not used, the support pin 212
Is connected to the support ring 206 in a state of being hung from the screw 207 of the support ring 206 by a chain 220. However, when the support ring 206 is rotated in this state, the rotating operation cannot be performed smoothly, and the operability is reduced. Is bad. (4) As described above, the support 200 is mainly used for slab concrete formwork. That is, the support 200 is used in such a form that the load acting on the receiving plate 208 of the insertion pipe 210 adjusted to a predetermined height is received by the upper end surface of the support ring 206 via the support pin 212. Therefore, the support 200 can be used as a support material, but cannot be used as a tensile material.

A first technical object of the present invention is to provide an improved support capable of stably supporting a load at a relatively high position.

A second technical object of the present invention is to provide an improved support which can easily perform a rotation operation of the support ring means even under a heavy load.

A third technical object of the present invention is to provide an improved support capable of reliably preventing the support pin from being lost without causing any trouble in the rotating operation of the support ring means.

A fourth technical object of the present invention is to provide an improved support which can be used as a tensile member.

[0017]

According to one aspect of the invention, the support comprises a plurality of plug-in pipe means, including plug-in pipe means that plug into the support pipe means. The insertion pipe means other than the insertion pipe means inserted into the support pipe means also has a plurality of pairs of pin holes penetrating from one side of the outer peripheral surface to the other at an axial interval. Each of the plug-in pipe means
Each of the pin hole pairs of the upper plug-in means is configured such that the lower end side of the upper plug-in means can be inserted into the upper end side of the lower plug-in means. Are positioned relative to each other so as to be aligned with each of the pin hole pairs of the lower insertion pipe means. The axes of the respective pairs of pin holes formed in each of the plug-in pipe means are alternately arranged with a 90 ° offset in the circumferential direction. The upper plug-in means is inserted into the lower plug-in means and each pin hole pair of the upper plug-in means in the plug-in part is aligned with each pin-hole pair of the lower plug-in means. In the above, at least two support pins are detachably inserted into the corresponding pin hole pairs with a shift of 90 °, whereby the upper insertion pipe means is supported by the lower insertion pipe means.
Thus, the deflection of the upper bayonet pipe means with respect to the lower bayonet pipe means is firmly prevented by the at least two support pins in two directions which are orthogonal to each other. As a result, even when a plurality of, for example, two to four plug-in pipe means are connected, the blurring of each plug-in portion is prevented, and the load can be stably supported at a relatively high position. It is important that at least two support pins are inserted into pin hole pairs located at a 90 ° offset, and may be inserted into adjacent pin hole pairs in the axial direction, or may be separated from each other in the axial direction. May be inserted into the pair of pin holes. By increasing the number of support pins used, the anti-shake effect and the support strength are increased.

According to another aspect of the present invention, the rotating operation handle means of the support ring means includes a pair of rotating operation handles. One end of the pair of rotary operation handles is rotatably supported on the outer peripheral portion of the support ring means at positions separated from each other by 180 °. Therefore, since the support ring means can be rotated by both hands by using the pair of rotation operation handles, the rotation force is doubled as compared with the conventional one-handed rotation. Therefore, even with the same load, the support ring means can be rotated more smoothly and smoothly, and the working efficiency can be improved. Also, labor is greatly reduced. Further, since the rotary operation handle is not hit with a hammer or the like, it is possible to prevent troubles such as damage or breakage thereof and breakage of the screw portion of the support pipe and the support ring means.

According to still another aspect of the present invention, the rotary operation handle is formed of a round pipe member, and a female screw means is formed on an inner peripheral portion at the other end. A male screw portion is formed at one end of the support pin, and a plate-like portion having a width on both sides larger than the outer diameter of the support pin is formed at a part of one end of the male screw portion. The support pin is inserted into the rotary operation handle from the other end side, and the other end of the male screw portion of the support pin is engaged with the female screw means of the rotary operation handle, so that the support pin is detachably held on the rotary operation handle. Is done. Therefore, when the support pin is not used, it is inserted into the rotary operation handle and screwed only by rotating it, and the support pin is housed in the support pin, so that the loss can be reliably prevented. Moreover, since the chain is no longer used to prevent the support pin from being lost as in the past, there is no problem in rotating the support ring means.
A smooth rotation operation is guaranteed.

According to still another aspect of the present invention, the support ring means includes a main support ring member having an internal thread formed on an inner peripheral portion, and an upper thrust bearing means with respect to an upper end of the main support ring member. An upper support ring member rotatably connected, and a lower support ring member rotatably connected to a lower end of the main support ring member via lower thrust bearing means. Rotation operation handle means is mounted on the outer periphery of the main support ring member. When the insertion pipe means is inserted into the support ring means and the support pin is inserted on the upper side of the support ring means through the pair of long holes and the pair of pin holes, both ends of the support pin are the upper end surface of the upper support ring member. Placed on. As a result, the insertion pipe means is supported on the support pipe means so that the height thereof can be adjusted. Therefore, in a state where a heavy load such as a concrete slab is acting on the insertion pipe means, the main support ring member is rotated by the rotation operation handle means in order to move the insertion pipe means downward. The upper support ring member does not rotate because the heavy load acts on both ends of the support pin on the upper end surface thereof. However, due to the function of the upper thrust bearing means interposed between the main support ring member and the upper support ring member, only the main support ring member can be rotated very easily by hand. Therefore, even when a heavy load is applied, the rotation operation of the main support ring can be performed very easily, and the insertion pipe means can be easily moved downward.

In the present invention, as described above, the insertion pipe means is mounted on the upper end surface of the upper support ring member via the support pin so that the height of the support pipe means can be adjusted freely. It is configured to be. This function is mainly used for slab concrete formwork, but also has a function suitable for other struts or supports. That is, by rotating the main support ring member, the insertion pipe means is configured to extend in the axial direction with respect to the support pipe means. It can be preferably used as a bracing material or a supporting material by arranging the intervening member or a certain member to be supported and extending the insertion pipe means in the axial direction. The supports are arranged not only vertically but also horizontally or diagonally. At this time, the function of the upper thrust bearing means makes it easy to rotate the main support ring member even under heavy load, so that the tension operation and the tension release operation can be performed very lightly.

On the other hand, according to the present invention, the support ring means includes the lower support ring member rotatably connected to the lower end of the main support ring member via the lower thrust bearing means. Therefore, when the support pin is inserted through the long hole pair and the pin hole pair below the support ring means, both ends of the support pin are positioned on the lower end surface side of the lower support ring member. Thereby, the support can be suitably used as a tension member. That is, one end of the support pipe means is fixed to, for example, the mounting surface, the upper end of the insertion pipe means is locked to the member to be pulled,
By rotating the main support ring member, the insertion pipe means is axially reduced relative to the support pipe means, so that the member to be pulled is pulled against the mounting surface. At this time, the rotation of the main support ring member is easy even under heavy load by the function of the lower thrust bearing means, so that the tension operation and the tension release operation can be performed very lightly.

According to still another aspect of the present invention, the support ring means comprises: a main support ring member having an internal thread formed on an inner peripheral portion; and an upper thrust bearing means provided at an upper end of the main support ring member. And lower thrust bearing means provided at the lower end of the main support ring member. Rotation operation handle means is mounted on the outer periphery of the main support ring member. The function of this invention is substantially the same as that of the invention described above. However, according to this structure, since the existing thrust bearing can be used, it can be manufactured at a relatively low cost.
