DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a vertical pipe when constructing a vertical pipe of a building, a temporary fixing device for vertical pipe construction suitable for use in the method for constructing a vertical pipe, and a vertical pipe. The present invention relates to a jig for preventing pipe breakage for pipe construction.

[0002]

2. Description of the Related Art When vertical pipes for various building equipment such as air conditioning equipment and sanitary equipment are to be piped to a high-rise building, a predetermined plurality of pipes that are vertically piped are connected to a vertical pipe unit using a frame, a fixing member, or the like. Conventionally, a construction method has been employed in which a unit is lifted up vertically in a vertical state by a building-side lifting machine, for example, a tower crane or the like. According to such a construction method, the installation work of the vertical pipe to the building and the construction of the steel frame in the construction work can be performed at the same time, and the easiness of the construction and the shortening of the construction period can be achieved.

[0003]

However, according to the above-mentioned conventional method, it is necessary to determine the installation at the design stage at an early stage from the viewpoint of structural reinforcement and fabrication of a steel frame, and it is difficult to make subsequent corrections. Moreover, since the vertical pipe unit is prefabricated in the factory in advance, factory processing costs are separately required.
Furthermore, since a tower crane is used, coordination with other users in the building was necessary, and the construction could not proceed independently. In addition, while the upper pipe is suspended by a tower crane, the lower pipe must be centered and the pipes must be connected and fixed by welding or the like, so that the connection work is not easy.

[0004] The present invention has been made in view of the above point, there is no need to particularly determine the construction at an early stage, no prefabricated work in the factory, and without using a so-called long lift such as a tower crane. It is a first object of the present invention to provide a vertical pipe construction method capable of constructing a vertical pipe. A second object of the present invention is to provide a temporary fixing device for vertical pipe construction that can suitably carry out such a vertical pipe construction method. Furthermore, the present invention
It is a third object of the present invention to provide a pipe bending prevention jig for vertical pipe construction, which can prevent the pipe from being bent or broken when implementing such a vertical pipe construction method.

[0005]

According to the first aspect of the present invention, in order to achieve the first object, when a vertical pipe is constructed in a building, the vertical pipe is located at an upper side of a pipe material for forming the vertical pipe. The pipe is temporarily fixed to the building side at a predetermined temporary fixing point in a vertical state, and then the lower tube is pushed up vertically to connect and fix the lower part of the upper pipe and the upper part of the lower pipe, and then A method for constructing a vertical pipe is provided, wherein the temporary fixing is released and the lower tube is pushed up to a position required for temporary fixing at the predetermined temporary fixing place.

According to a second aspect of the present invention, in constructing a vertical pipe in a building, of the pipes constituting the vertical pipe, first, a pipe material to be piped at an uppermost portion is vertically fixed in a predetermined state. Push up to the position required for temporary fixing at the point,
Next, the pipe material is temporarily fixed to the building side at the predetermined temporary fixing point, and then another pipe material piped under the pipe material is pushed up in a vertical state, so that the lower portion of the previous pipe material and the other pipe material are A vertical pipe construction method is provided, wherein the temporary pipe is fixed to the upper portion, and then the temporary fixing is released, and the other pipe material is pushed up to a position necessary for temporary fixing at the predetermined temporary fixing point. Is done.

As described above, according to the vertical pipe construction method of the first and second aspects, the pipe material located on the upper side is temporarily fixed to the building side at a predetermined temporary fixing point in a vertical state, and then the pipe material located on the lower side. Is pushed up in a vertical state to connect and fix the lower part of the upper tube and the upper part of the lower tube, so that the pipes can be easily centered and the connection operation is easier than before. Moreover, since the lower tube is pushed up, a tower crane is not required, and the construction can be carried out independently, and there is no need to determine the construction schedule early in the design stage. It is not necessary for the tube material to have a unit configuration by prefabrication. Needless to say, when pushing up a plurality of pipes simultaneously, a plurality of pipes can be constructed quickly. As a means for pushing up the tube, an appropriate jack can be used. Here, the term “temporary fixing” refers to a state in which the pipe is fixed to the building so as not to fall at least, and may be one that does not hinder the upward movement of the pipe.

In the vertical pipe construction method according to the first and second aspects, when the pipe is pushed up in a vertical state, as described in the third aspect, a guide rail having at least the length of the pushed up length is previously erected, At least the lower end of the pipe is supported on a mount that can be raised along the guide rail, and the pipe is pushed up by raising the mount, so that the pipe can be easily and smoothly pushed up vertically. . Therefore, even when a plurality of pipes are pushed up at the same time, it is possible to easily push up the plurality of pipes by setting the plurality of pipes on the mount and raising the mount.

In the case where at least the lower end of the tube is supported by the mount, the support can be easily realized by providing a mount such as a socket for receiving the lower end of the tube in the mount. Therefore, even when a plurality of pipe members are pushed up at the same time, a plurality of such receiving portions may be provided.

According to a fourth aspect of the present invention, there is provided an apparatus having a projection on an outer periphery for temporarily fixing a pipe vertically piped to a building to the building in a vertical state. hand,
A plurality of locking members that are rotatable only upward from the horizontal state are attached to appropriate members on the building side, and each of the locking members is formed with a notch, and each of the locking members is in a horizontal state. In the configuration, the mounting position of each locking body and the shape of the notch portion are configured such that the opening of the main body of the pipe material can only pass through the collection of the notch portions. A temporary fixing device for vertical pipe construction is provided.

If this temporary fixing device for vertical pipe construction is used,
The tube is raised from below with the target of the opening, and further raised so that the top of the tube passes through the opening, and since the opening is shaped to pass only the main body of the tube, the outer periphery of the tube is The periphery of the opening is locked to the protrusion of
The locking body rotates upward with the rise of the tube material. Then, when the pipe is further raised, the locking of the periphery of the opening is released, and the locking body returns to the horizontal state again by its own weight. When the tube is lowered at this point, the projection on the outer periphery of the tube is locked to the periphery of the opening. Since the locking body can rotate only upward, even if the support of the tube material is released at this point,
The tube material is suspended from the temporary fixing device, so that it is temporarily fixed. Therefore, when the method for constructing a vertical pipe according to the first or second aspect is used, if the temporary fixing device according to the third aspect is used, the temporary fixing is automatically performed only by pushing up and down the pipe material. In addition, since the pipe material is in a hung state as it is, the raising operation of the pipe material is free.

According to a fifth aspect of the present invention, there is provided a jig for vertically mounting a vertical pipe on a building and fixing the pipe to the building, the jig being fixed to the building. A pipe breaking prevention jig for vertical pipe construction is provided, comprising: a main body; and at least a pair of roller members attached to the main body and facing each other with the pipe material interposed therebetween.

Therefore, by disposing the pipe breaking preventing jig for vertical pipe construction on the rising path of the pipe, the rising pipe is guided by the roller member and the right and left movement is regulated, so that the pipe may be bent. Breaking can be prevented.

It is possible to cope with the simultaneous construction of books, and according to the latter, there is an advantage that if the diameters of the pipes to be constructed at the same time differ greatly, it can be dealt with by installing them individually.

The temporary support device 41 shown in FIG. 4 is provided at four places on the upper support 14. The temporary fixing device 41 includes two steel materials 1 forming the upper support base 14.
It is constituted by two locking members 42 and 43 which are rotatably mounted over 4a and 14b. The locking members 42 and 43 have a symmetrical shape and are arranged to face each other such that the insides thereof abut each other.
A rotatable member 44 such as a hinge is attached between the vicinity of both ends of a and the steel materials 14a and 14b, so that the rotatable member 44 is rotatable only upward from a horizontal state. As a material of the temporary fixing device 41, a steel plate having a thickness of 20 mm can be exemplified.

Further, semicircular notches 42b and 43b are formed on the inner sides of the engagement members 42 and 43 on the butting side. Then, as shown in FIG. 4, in a state where the locking members 42 and 43 are in a horizontal state and their inner sides abut each other, a circular opening H is formed by these two notches 42 b and 43 b. The inner diameter of the opening H is set to be slightly larger than the outer diameter of the pipe material P, and is set to be smaller than the outer diameter of the collar pf.

On the other hand, a socket-shaped receiving portion 13a for receiving the lower end portion of the tube material P is provided on the front mounting base 13 on a support column 13b fixed to the upper surface of the mounting base 13 in a plurality (4 in this embodiment). One) is provided. Preparation is completed when the push-up device 10, the pipe break prevention jig 31, and the temporary fixing device 41 are set as described above. Next, the construction procedure will be described.

In the method for constructing a vertical pipe according to the present embodiment, as shown in FIG. 5, a flange pf constituting the projection according to the present invention is attached to the outer periphery near the upper end of the pipe material P by welding or the like. Is used. Of course, the shape of the protrusion is not limited to such a flange portion pf, but may be any shape as long as it protrudes to the outer periphery. A well-known connection socket can also be used as the collar pf.

Then, the pipe material P1 to be piped at the uppermost portion is hung by an appropriate hanging member, and as shown in FIG.
The lower end is inserted into the receiving portion 13a of the gantry 13 and set. At this time, the upper part of the pipe material P1 is inserted between a pair of roller members 35, 35 of the pipe break prevention jig 31 facing each other.

Next, the motor 22 on the upper support 14 and the motor 24 on the gantry 13 are operated. When the motor 22 operates, the screw rod 15 itself rises, and the screw rod connection jigs 17 rise accordingly. On the other hand, the gantry 13 moves up along the guide rails 11 and 12 by the operation of the motor 24. Therefore, the gantry 13 rises by the rise of the screw rod 19 itself and the rise along the screw rod 19,
Thereby, the four pipe members P1 set in the receiving portion 13a of the gantry 13 are pushed upward as shown in FIG.

As shown in FIG. 8, when the pipe material P1 is pushed upward, the pipe material P1 is opened on the opening H of the temporary fixing device 41 provided above the sleeve 3a of the third floor 3 of the third floor. When the pipe material P1 is pushed upward as it is, the opening H has a shape that allows only the main body of the pipe material P1 to pass therethrough. Notch 42 of locking body 42, 43

As shown in FIG. 9, each locking body 42, 43 is opened and lifted.

Still further, when pushed up as it is, each locking body 4
The engagement of the flange portion pf of the pipe material P1 with the notch portions 42b, 43b of the pipes 2, 43 is released, and as shown in FIG. become. At this point, the lifting of the pipe material P1 is stopped, and the motors 22 and 24 are rotated in reverse, and
Is lowered to gradually lower the pipe material P1, and as shown in FIG. 11, the flange portion pf of the pipe material P1 is inserted into the peripheral portion of the opening H, that is, the notch portions 42b, 43b of the locking members 42, 43. The tube material P1 is locked and suspended in the temporary fixing device 41, that is, in a temporarily fixed state.

The gantry 13 is lowered as it is, and is stopped again at the pipe material setting position as shown in FIG. Next, as shown in FIG. 13, a tube P2 connected to the lower end of the tube P1 is set in the receiving portion 13a of the gantry 13.
Next, the motors 22 and 24 are operated again to the upside, and the pipe material P2 is pushed up as shown in FIG.

When the lower end of the tube P1 comes into contact with the upper end of the tube P2, the motors 22, 24 are stopped and the pedestal 13 is stopped, and the lower end of each tube P1 and the upper end of each tube P2 are stopped. The part is connected and fixed by welding or the like. When the connection and fixing work is completed, the motors 22 and 24 are operated again to raise the gantry 13 and push up the pipes P1 and P2 together.

When the pipe P2 is pushed up, the flange pf of the pipe P2 is temporarily fixed to the temporary fixing device 4 of the upper support base 14.
When the first locking members 42 and 43 are pushed up and the pipe material P2 is still pushed up as it is, the locking members 42 and 43 return to the horizontal state by their own weight, as in the case of the pipe material P1. At this point, when the pedestal 13 is lowered by rotating the motors 22 and 24 in the reverse direction, the pipe material P2 is temporarily fixed to the temporary fixing device of the upper support 14 as shown in FIG. In the figure, reference numeral 4 denotes a floor portion of the fourth floor. Then, as shown in FIG. 16, the gantry 13 is lowered again to the set position of the tube material and stopped. Then, in the same procedure, the next tube is sequentially attached to the gantry 13.
Is set in the receiving portion 13a, and the next tube is pushed up again in the same operation procedure.

As can be seen from the above work procedure, according to the vertical pipe construction method according to the present embodiment, since the tower crane is not used first, the construction can be carried out independently, and the tower which has been troublesome until now can be obtained. Coordination with other construction methods for the use of cranes is not required. Therefore, it is not necessary to determine a construction schedule early in the design stage, and it is possible to respond to a subsequent correction. In addition, the construction period of other construction methods using the tower crane can be shortened accordingly.

Further, since the connection between the lower end of the upper tube and the upper end of the lower tube is made by pushing up from below, the alignment is easy, and the connection and fixing work can be performed more simply and quickly than before. Can be performed with high accuracy. In the present embodiment, particularly, the lower end of the pipe P is inserted into the receiving portion 13a of the pedestal 13, and the pedestal 13 pushes up the pipe P, so that a stable lifting operation can be performed.
In addition, since both ends of the gantry 13 are slidable along the guide rails 11 and 12, a more stable lifting operation is possible.

The used pipe material P itself also has a collar portion p on the outer peripheral portion.
Since only the processing of providing f is required, the processing is simpler than the conventional vertical tube unit, and the cost can be reduced. Note that, instead of the flange portion pf, a shape forming a protrusion on the outer periphery may be appropriately selected.

Further, in the method for constructing a vertical pipe according to the present embodiment, since the pipe break prevention jig 31 is used,
The pushed-up pipe material P does not bend, fall or break inside. The jig 31 for preventing pipe breakage may be installed on all floors, or may be installed as needed. Further, it may be installed on the lower surface of the floor or in the space between the floors.

Regarding the temporary fixing of the pushed-up pipe material, since the method of constructing a vertical pipe according to the present embodiment uses the temporary fixing device 41 shown in FIG. 13, the pipe material P can be automatically temporarily fixed at a predetermined position by simply lowering the pipe 13.
There is no need for special temporary fixing work or dedicated personnel.

[0037]

According to the method for constructing a vertical pipe according to the first, second and third aspects, the connecting operation between pipes is easier than before. Moreover, since there is no need to use a tower crane, the construction can be carried out independently, and there is no need to determine the construction schedule early in the design stage. Since the tube does not need to be made into a unit structure by prefabrication, it is easy to manufacture and the cost is low. In particular, in the case of claim 3, it is possible to easily and smoothly push up the pipe vertically, and it is also easy to push up a plurality of pipes simultaneously.

By using the temporary fixing device for vertical pipe construction according to the fourth aspect, the pipe material can be automatically temporarily fixed only by raising and lowering the pipe material. Therefore, the method for constructing a vertical pipe according to claims 1 and 2 can be easily and suitably implemented.

According to the vertical pipe construction jig for preventing vertical pipe construction according to claim 5, when the pipe material is raised and lowered in a vertical state, even if the pipe material is long, it can be bent or broken on the way. Can be prevented. Therefore, the method for constructing a vertical pipe according to claims 1 and 2 can be suitably implemented.
