It relates to a lifting jig to be used.

[0002]

2. Description of the Related Art When pipes for various building equipment such as air conditioning equipment and sanitary equipment are piped to a high-rise building, for example, Japanese Patent Publication No.
As disclosed in No.-6904, a predetermined plurality of pipes vertically piped are unitized as a piping unit using a frame, a fixing member, and the like, and this is lifted on a building side, such as a tower crane. A so-called riser unit construction method of lifting vertically in a conventional manner has been employed. According to such a construction method, the installation work of the vertical pipe to the building and the steel frame construction method of the construction work can be performed at the same time.
The construction period can be shortened.

A piping unit used in such a riser unit method is a prefabricated unit usually manufactured and assembled in a factory or the like, and is mounted horizontally on a cargo bed of a vehicle such as a large truck to a construction site. Is transported. Thereafter, at the site, the piping unit is lifted to a predetermined floor by the following method. (1) The piping unit loaded on the truck bed is once unloaded to the ground, and then temporarily placed. Then, the tower crane lifts the pipe unit from one end. (2) The piping unit is unloaded from the truck bed by two cranes, a tower crane and a phase hanging crane separately provided from the tower crane. Next, the tower crane side is raised to suspend the piping unit in a vertical state. In this state, the method of releasing the mounting wire of the lifting crane and then lifting it with a tower crane.

[0004]

However, according to the above-mentioned method (1), the work of unloading the transported piping unit to the ground must be performed once, which takes much time and lengthens the construction period. This leads to higher costs. In addition, a space for temporary placement on the ground is required. In addition, since the tower crane lifts the pipe unit vertically from one end, the other end of the pipe unit may be damaged. In the method (2),
In addition to it must be installed separately the phase hanging crane tower crane, also must also be newly secured crane worker accordingly. In addition, there is a need for a space for the crane for lifting. In addition, since the posture was changed from a horizontal state to a vertical state in the air, work safety was not satisfactory.

[0005] The present invention has been made in view of the above, and can be lifted only by a tower crane, and even if it is lifted only at one end, there is no risk of damage to the other end. Further, it is an object of the present invention to provide a vertical pipe lifting jig used in a vertical pipe lifting method capable of lifting directly from a transport vehicle without requiring unloading and solving the above problem.

[0006]

Means for Solving the Problems First of all, in this specification, a vertical pipe material conveyed to a construction site is lifted in a vertical position, for example, in a vertical state, and is immobilized in a construction method in which pipes are vertically piped to a building. An appropriate lifting jig fixed to the object is provided with a fitting member that is rotatable in the rising direction and that creates a fitting relationship with one end of the tubular material constituting the vertical tubular material. A vertical tube is set so that one end of the tube has a fitting relationship with the fitting member, and a lifting jig is attached to the other end of the vertical tube, and then the lifting jig is attached to the lifting jig. A vertical pipe material characterized in that one end of a lifting member such as a wire lifted by a heavy machine is directly or indirectly locked, and in this state, the vertical pipe material is lifted by the lifting machine via the lifting member. Is proposed.

Here, the vertical pipe member refers to a pipe unit in which a plurality of pipe members are arranged at predetermined intervals as described above and made into a unit by a frame or the like, or a so-called pipe aggregate in which the plurality of pipe members themselves are directly bundled. It is a concept that includes. The term “lifting member” refers to a wire, a rope, or the like. To directly or indirectly lock one end thereof means that the end of a wire or the like is formed into a form that can be directly locked, or the wire is directly locked. Means that a connecting member such as a shackle and a locking member such as a hook are attached to the end of the bracket, and locked through the connecting member and the locking member. The lifting jig may be attached to the vertical pipe immediately before lifting, or may be attached in advance. The non-animal body is an immovable object for fixing so that the lifting jig itself does not move.

Further, the term "insertion relationship" as referred to in the claims of the present application means that an appropriate insertion portion provided on the insertion member is inserted into one end portion of the pipe member, or conversely, the insertion portion is provided on the insertion member. It means that one member is inserted into the other member by inserting one end of the tube material into an appropriate inserted portion.

In the case of lifting a horizontal pipe, for example, in a horizontal state in accordance with the above-described lifting method, an insertion portion of a fitting member, which is rotatable in a rising direction, is inserted into one end of the vertical pipe. Since the lifting jig having this insertion part, that is, the main body, is fixed to the immovable object, when the vertical end of the vertical pipe is lifted by a lifting machine such as a tower crane, the other end rises. The vertical pipe is gradually raised around the base of the rotatable insertion portion, that is, the center of rotation. At this time, the lifting jig itself having the insertion portion does not move because it is fixed to the non-animal body. Therefore, as the load is lifted as it is, the vertical pipe material is gradually raised, and this raising operation continues until the insertion portion comes out of the pipe material. When the insertion section comes out of the pipe, the vertical pipe is almost vertical or close to it. Thereafter, the vertical pipe may be lifted to a predetermined floor as it is in a normal operation. A series of processes as described above is performed when a lifting jig having an inserted portion into which one end of the tube is inserted is used as the insertion member, and one end of the tube is inserted into the insertion member. The same is true for

Therefore, the lift can be lifted only by the tower crane and there is no possibility of damaging one end of the vertical pipe. A series of operations can be performed safely. In view of such an operation, if the lifting member is lifted from directly above the center of rotation of the insertion member, the insertion relationship is released when the vertical tube material becomes vertical, that is, the insertion portion is Since one end of the tube material comes off or one end of the tube material comes out of the inserted portion, the one end of the tube material does not swing immediately after the insertion relationship is released. Therefore, safety is further improved.

[0011] lifting duty jig, if it is fixed to the vehicle carrying the vertical tube member such as a truck, or applying a parking brake so as not to move the vehicle itself, further placing an appropriate stopper before and after the tire By doing so, the lifting jig does not move during lifting, and the lifting operation can be performed without any trouble. In addition, since the lifting jig is fixed to the transported vehicle, the vertical pipes stacked horizontally on the vehicle can be directly lifted from the vehicle. Therefore, it is possible to carry out extremely quick lifting work, and at the same time unloading work,
No place for temporary placement is required.

[0012] Then, according to claim 1, longitudinally vertical tubing

This piping unit U is assembled in a factory or the like in advance.
At the building site, as shown in FIG. 5, for example, 3
The three piping units U1, U2, U3 are transported in a horizontal stack in three stages.

Each of the piping units U1, U2, U3 is
In the case of loading, the insertion portion 24b of the insertion member 24 of the lifting jig 1 is inserted into the other end of the pipe unit pipe material. For example, as shown in FIG. 2, the pipe unit U3 is stacked on the carrier 12 while inserting the insertion portions 24b of the insertion members 24 into the other ends of the pipe members 31 and 35 at both ends of the pipe unit U3. The piping unit U3 is tightly fixed to the carrier 12 with a band body (not shown). Similarly, other piping units U1 and U2 loaded above the piping unit U3 insert the corresponding insertion portions 24b of the insertion members 24 into the ends of the pipe members 31 and 35 and load the same on the loading platform 12.

The piping units U 1, U 1 stacked horizontally in this state and transported to the building site by the vehicle 11
2. U3 is sequentially lifted in the following procedure.

First, as shown in FIG. 5, a worker locks a lifting jig 43 on a hook 42 provided at an end of a lifting wire 41 of a tower crane (not shown). The jig 43 is attached via a shackle 44 to an appropriate portion of the piping unit U1, for example, to the pipe members 31 to 35, the fixing member 37, or the like. Alternatively, for example, an appropriate mounting hole may be formed in the guide 39, and the guide 39 may be hooked onto the hole. During this time, the piping operator releases the band body (not shown) which fixed the piping unit U1 to the bed 12 or the like. On the other hand, the driver of the vehicle is the vehicle 1

An appropriate stopper 45 is provided before and after 1a. Thereby, the immobility of the vehicle 11 is improved.

Next, when the wire 41 is wound up by operating the tower crane, the insertion portion 24b of the insertion member 24 of the lifting jig 1 is inserted into the other end of the pipe members 31, 35 in the piping unit U1. Moreover, since the vehicle 11 on which the lifting jig 1 is installed and fixed does not move, as shown in FIG. 6, the piping unit U1 is moved from the jig 43 side around the rotation center of the insertion member 24, that is, around the shaft 13. It is caused gradually.

When the wire 41 of the tower crane is still wound up and the pipe unit U1 is substantially vertical as shown in FIG. 7, the insertion portion 24b is connected to the other ends of the pipe members 31 and 35 in the pipe unit U1. Get out of the department. Thereafter, the tower crane is further operated in the same state, and the wire 41 is wound up, stopped at a predetermined point in the same manner as in the case of lifting of this type of piping unit, and the piping unit U1 is built into the building. You only need to do it.

Similarly, in the next piping unit U 2, as shown in FIG. 8, first, a lifting jig 46 is locked to the hook 42 of the wire 41, and this jig 46 is connected to the piping unit via the shackle 44. Attach it to one end of U2, and then wind up the wire 41 as it is.
The piping unit U2 horizontally stacked in 2 can be directly lifted.

As described above, according to the lifting method using the lifting jig 1 according to the present embodiment, first, the loading platform 12 of the vehicle 11 is used.
The piping unit U1~U3 that was horizontal stacking is, without unloading on the ground, can be Agekasane in the directly as a vertical position just tower crane. Therefore, the time for unloading can be omitted, and there is no need to separately secure a place for temporary storage. Moreover, since the lift can be carried out only by the tower crane, the crane for suspending is unnecessary. In addition, in the process of moving from the horizontal stacking state to the vertical state, the piping units U1 to U3 are caused by the smooth rotational movement around the shafts 13, 14, 15 of the lifting jig 1 located at the other end. So
The other ends of the piping units U1 to U3 are not damaged.
In addition, as can be seen from the work procedures in FIGS. 5 to 8, the work environment is safer than before.

In the lifting jig 1 according to the embodiment, since the insertion member 24 is slidable in the axial direction of the shafts 13, 14, 15, the piping units U1 to U3 are provided.
Can be adjusted to the interval of the pipes into which the insertion portions 24b are inserted, and can be used for various types of piping units, and the lifting operation can be performed under the most preferable conditions.

In the lifting jig 1 according to the above-described embodiment, two insertion members 24 are mounted on one shaft so that the insertion members are inserted into the other ends of the pipes at both ends in the piping units U1 to U3. 24b was inserted, but the number of insertion members 24 rotatably mounted on one shaft is not limited to this, and the number of piping units U1 to U3 is not limited to this.
Can be appropriately increased or decreased according to the size, weight, and number of pipes.

Further, the insertion portion 24b of the insertion member 24
If a suitable cushioning material such as urethane is arranged on the base side of the pipe, the ends of the pipes 31 and 35 into which the insertion portions 24b are inserted are inserted in the process of erecting the piping units U1 to U3. Even if it comes into contact with the base of the member 24, the impact can be absorbed and the protection of the end portion of the tube material can be further improved.

In the above-described embodiment, the insertion member 24 having the substantially cylindrical insertion portion 24b shown in FIG. 3 is used as the insertion member.
An insertion member having a configuration in which an inserted portion having an inner diameter into which the end portions 1 and 35 are inserted is provided in the main body 24a may be used. In this case, the inserted portion can be easily configured by appropriately cutting the pipe material. In addition, even if it is the structure which inserts the tube materials 31 and 35 in such a way, if the above-mentioned buffer material is provided in the bottom of the to-be-inserted part, protection of the tube material end can be improved.
