Description

  The present invention relates to an installation method for equipment piping used for building piping such as buildings and electrical wiring, and a joint plug for equipment piping.

Recently, a mountain-shaped deck plate is often used for a floor frame of a building or the like.
For this reason, when installing equipment piping on the deck plate, the sleeve is fixed to the flat surface of the deck plate, and through holes are formed in the deck plate in the sleeve after placing concrete on the outer periphery. The sleeve can only be attached to the flat surface of the deck plate, and the installation position of the equipment piping is limited.
Further, since the sleeve is attached to the deck plate, there is a disadvantage that it takes time and increases the cost.
JP 2001-81963

    In view of the above-mentioned conventional drawbacks, the present invention can easily install equipment piping at any position of the deck plate, and has through holes formed in the deck plate and equipment piping inserted into the through holes. It is an object of the present invention to provide an installation method for equipment piping and a joint plug for equipment piping that can be installed at low cost and can be easily filled with mortar and concrete.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention penetrates a through hole formed in the deck plate through hole forming step of forming a through hole in the deck plate of the part where the equipment piping is installed, and the deck plate through hole forming step. Equipment piping arrangement process for positioning equipment piping, and a lower joint for equipment piping that is detachably attached to the outer peripheral portion of the equipment piping arranged in this equipment piping placement process and in contact with the bottom surface of the deck plate An outer joint that can be bent into a cylindrical shape with an elastic material that is mounted on the lower joint-filling mold for equipment piping at the outer periphery of the equipment pipe and into the through hole of the deck plate at the outer periphery of the equipment piping After the installation process of the equipment piping joint filling tool to be attached to the filling form and the installation process of the equipment piping joint filling tool, a mortar or a cup is provided between the outer periphery joint filling form and the equipment piping. The cleat constitutes a method of installing the equipment piping and pouring process of pouring to mortar and concrete.

  The present invention relates to a lower joint clogging form for equipment piping that can cover a through hole of a deck plate that is detachably attached to an arbitrary outer periphery of equipment piping, and is inserted into a through hole formed in the deck plate, A joint plugging tool for equipment piping is constituted by an outer peripheral joint plugging mold that can be bent into a cylindrical shape by an elastic material that can be positioned on the lower pipe filling mold for equipment piping.

  As is clear from the above description, the present invention has the following effects.

(1) Deck plate through hole forming step for forming a through hole in a deck plate at a site where equipment piping is installed, and equipment for positioning the equipment pipe so as to pass through the through hole formed in this deck plate through hole forming step A piping placement step, and a facility pipe lower joint clogging form that is detachably attached to the outer peripheral portion of the portion of the equipment piping placed in contact with the bottom surface of the deck plate placed in the equipment piping placement step, and Equipment piping for attaching an outer periphery jointed formwork which can be bent into a cylindrical shape with an elastic material whose lower part into the through hole of the deck plate is located on the lower jointing formwork for equipment piping at the outer periphery of the equipment pipe A mortar in which mortar or concrete is placed between the outer peripheral joint filling form and the equipment pipe after the joint filling equipment installation process and the equipment piping joint filling process Because it consists of a concrete placing step, the through hole formed in the deck plate and the outer periphery of the equipment pipe inserted into the through hole and the bottom surface of the deck plate in the part where the through hole is formed are the lower part for the equipment pipe It can be covered with a joint-filling formwork and an outer peripheral joint-filling formwork.
Therefore, mortar and concrete can be filled and sealed in the gaps between the upper surface of the lower joint mold for equipment piping and the outer peripheral portion of the equipment piping and the outer joint joint mold.

One installation pipe lower joint form frame 27 comprising an attachment piece 24 having an engagement hole 23 and an engagement member 26 having an engagement piece 25, and the other attachment piece 28 having a semicircular arc shape. The other flange piece 29 having a semicircular arc shape protruding outward from the upper end portion of the other attachment piece 28, the both end portions of the other attachment piece 28, and the other flange piece 29 of the part are integrally formed. Engagement hole 2 in one lower piping formwork 27 for equipment piping And it is composed of a engaging piece 25 and the other equipment piping lower joint filling mold 34 consisting of the mounting piece 33 having an engagement member 31 and the engaging hole 32 has an engaging to the engaging piece 30.

Further, as shown in FIG. 12, the outer peripheral joint mold 8 is pressed against the wall surface of the through hole 3 by inserting an elastic material such as stainless steel or an elastic steel plate into the through hole 3 by bending it into a cylindrical shape. What was formed in the magnitude | size which keeps a cylindrical body in the state which was made is used.
For this reason, the lower joint capping mold 7 for equipment piping has the engagement holes 23, 32 and the engagement holes 25 in the equipment piping 5 at a position where the bottom face of the deck plate 2 is covered with one flange piece 22 and the other flange piece 29. , 30 to be engaged with each other.
At this time, in order to fix the equipment piping 5 and the lower joint form 7 for equipment piping, the wedge 35 is driven and fixed between the equipment piping 5.
In addition, when a bare bear arises between the equipment piping 5 and the lower jointing formwork 7 for equipment piping, jointing materials, such as paper and cloth, are inserted.

Next, the outer peripheral joint form 8 is rolled into a cylindrical shape, and the lower part into the through hole 3 of the deck plate 2 is connected to one flange piece 22 and the other flange piece 29 of the lower joint form form 7 for equipment piping. By pushing in so as to be supported, the lower part and the outer peripheral part of the through-hole 3 formed in the chevron-shaped part of the deck plate 2, as shown in FIG. 13 and FIG. The facility pipe joint filling tool 36 including the outer joint joint form 8 can be covered so as not to leak even when mortar or concrete is filled.

The above-described installation method 1 for equipment piping uses the through-hole forming grinder 20, the lower joint clogging mold 7 for equipment piping, and the outer crevice clogging mold 8 to provide equipment piping 5 at any position on the deck plate 2. Can be installed easily and safely.
