Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a method for hoisting piping, and more particularly to an integrated hoisting method for hoisting a product that has been integrally assembled on a floor together with a surface plate.

[Conventional technology]

Conventionally, the work process for installing piping or ducts in the ceiling of each floor of a building was as follows. In other words, a wooden scaffold or hanging scaffold is constructed in advance at the location where the product is to be lifted, the hanging fittings are attached to the embedded hardware embedded in the underside of the ceiling floor, and each item is lifted onto the scaffold one by one using a lifting means such as a chain block. The pieces were hoisted up, and the individual parts were pieced together on scaffolding.

[Problem to be solved by the invention]

However, with such conventional construction methods, not only does scaffold construction work occur from the floor, but also the scaffolding that has been constructed can be damaged when lifting products and pulling them onto the scaffolding.
Interference or obstruction may occur, requiring partial dismantling of the scaffolding. Furthermore, this construction method not only requires a large number of workers for each lifting of the product, but also requires temporary materials and equipment, which requires a great deal of effort to operate. Furthermore, since the work of assembling the scaffolding and the work of integrating the products are performed at heights, there is a drawback in terms of safety, such as a high degree of risk. An object of the present invention is to provide a method for integrally lifting piping and ducts, which eliminates the drawbacks of the conventional method, has good working efficiency, and is highly safe.

[Means to solve the problem]

This construction method is thought to be efficient in hoisting a product in which pipes and ducts are joined together on the floor, and as a means of lifting, instead of metal fittings embedded in the underside of the ceiling floor, a sleeve that penetrates the upper floor is used. The construction method was to pass a wire rope through the inside and lift it from above the upper floor. In other words, the integrated lifting method for piping according to the present invention is a method for lifting and setting piping and ducts inside a building, in which a support rod is erected on a single-item assembly surface plate placed on the floor. It is connected to a lifting rope hanging down through the upper floor panel, and after assembling individual pieces of piping to each other in advance on the surface plate, the surface plate is hoisted by winding up the lifting rope, and the support rod is It is constructed so that it is connected to the existing piping on the surface plate by penetrating the upper floor panel and fixing it.

[Effect]

When lifting and setting piping and ducts inside a building at a construction site, a surface plate that also serves as a scaffold is placed on the floor in advance. Single items of the same type can be pre-assembled into one piece. On the other hand, at the lifting position of the ceiling, several lifting wire lobes are lowered by passing sleeves or the like through the floor plate at the upper corner thereof, and these are connected to the tips of support rods provided on the surface plate. The pipes and ducts integrated on the floor are wound around the wire robe using a winch installed on the floor in the upper corner along with the surface plate, and lifted up. Then, the support rod is inserted into the lobe penetration portion at the upper corner and fixedly supported, thereby fixing the surface plate to the floor plate at the upper corner. In this state, the surface plate is held fixed, so that connections to existing piping can be made stably and safely. After completing the work, it is sufficient to suspend only the surface plate by reversing the setting work described above.

【Example】

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the method for integrally lifting piping according to the present invention will be described in detail below with reference to the drawings. Figure 1 shows the assembly diagram on the floor, Figure 2 shows the lifting diagram.
FIG. 3 shows a sectional view of the lift. As shown in these figures, in order to carry out this construction method, a surface plate 12 that is initially placed on a floor 10 is used. This surface plate 12 serves both as a workbench and a scaffold for work, and is formed into a rectangular flat plate made of trussed steel sections. The planar size is such that a plurality of single ducts (or piping) 14 to be worked on can be arranged simultaneously. Such a surface plate 12
Support rods 16 are fixed to the four corners of the outer periphery via connection clamps 17, and are placed at a position sufficiently higher than the single duct 14 placed on the surface plate 12. It has a length that reaches . A male thread is cut at the end of the rod. On the other hand, a penetration sleeve 20 is buried in the upper corner floor plate 18 constituting the ceiling of the floor on which the surface plate 12 is placed, corresponding to the support rod 16, in advance at the time of concrete pouring. . There is a winch 2 on the floor in the upper corner.
2 and a guide pulley 24 are installed, and a wire lobe 26 for lifting to the right that is fed out through these is suspended above the surface plate 12 through the penetration sleeve 20 and connected to the tip of the support rod 16. . Strut rod 1
6 and the rope 26, a nut 28 which can be screwed onto the male thread at the tip of the rod 16 is passed through the rope 26. Scaffolding boards 30 are attached to both sides of the upper surface of the surface plate 12, and handrails 32 serving as a protective fence are also provided. The operations performed using such equipment are as follows. That is, the individual ducts 14 are arranged on a surface plate 12 placed on the floor 10, and are integrated on the surface plate 12 by bolts, welding, etc. to the extent that they can be loaded. A hoisting wire rope 26 is suspended from a guide pulley 24 installed on the upper floor through a through-sleeve 20 provided on the floor panel 18 at the upper corner, and is attached to the tip of each support rod 16. Link. In this case, rope 2
Pass nut 28 through 6. Multiple single ducts 1 on the surface plate 12 above the lower floor 10
4 is assembled into one unit, the necessary safety equipment, scaffolding board 30, and handrail 32 are installed on the surface plate 12, and the surface plate 12 is assembled together with the hoisting winch 22 installed on the floor of the upper floor. lift. Then, the support rod 16 is inserted into the penetrating sleeve 20 of the floor board 18 on the upper floor, and the tip thereof is made to protrude from the upper floor surface. Once it has been lifted to a predetermined setting level, the support rod 16 is held down using the tightening nut 28 passed through the wire rope 26 in advance and the holding plate 34 which has a split structure.
Cut off wire rope 26. In this state, installation work such as supports is carried out, and upper part work such as ducts and piping is completed. When the installation work at the upper part is completed, the lifting work is reversed and dismantled, but the installed pipes and ducts 14 are left at the upper part, and only the surface plate 12 is lowered to the floor 10. The penetration sleeve 20 embedded in the upper floor is filled with grout and closed after use. As a result, even if the installation building is for nuclear equipment, there is no effect on radioactivity. In the above embodiments, a method of lifting the product together with the product has been described, but this may also be a method of lifting only the scaffolding equipment, which is a combination of several stages of scaffolding.

【Effect of the invention】

As explained above, the construction method according to the present invention involves installing support rods upright on a surface plate for assembling single items placed on the floor, and connecting the support rods to a lifting rope that passes through the upper floor board and hangs down. ,
After assembling individual pieces of piping on the surface plate in advance, the surface plate is lifted by winding up the lifting rope, and the support rods are passed through the upper floor board and fixed, thereby lifting the pipes onto the surface plate. Since the connection to the existing piping is made at , it is possible to use a lifting method that is superior in work efficiency and safety and can reduce the number of man-hours.
