DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded type through sleeve for a building for collective piping.

[0002]

2. Description of the Related Art In a building air conditioner, a large number of outdoor units are installed on the roof of a building, and a pair of refrigerant pipes and a single line are provided between the indoor units on each floor of the building and the corresponding outdoor units on the roof. (Hereinafter referred to collectively as refrigerant pipes, etc.).

For this reason, a hut-like building (commonly known as a pigeon hut) 1 as shown in FIGS. 4 and 5 is built on the roof of the building, and the side wall 1a of the building 1 for collective piping is constructed. Embedment type penetrating sleeve 3 forming pipe opening 2
Is embedded when concrete is poured during construction of the collective piping structure 1, and the food box 4 is fixed to the outside of the penetration sleeve 3.

[0004] Refrigerant pipes 5 and the like from the indoor units on each floor are joined together in a pipe duct penetrating the building in the height direction and piped into the rooftop collective pipe building 1 to form a pipe opening. From the section 2 through the food box 4, piping is carried out along the rack 6 installed on the roof. Each individual outdoor unit (not shown) installed in the vicinity of the rack 6
The refrigerant pipes 5 are drawn out from the rack 6 and connected thereto.

Conventionally, as shown in FIGS. 4 and 5, the embedded type penetrating sleeve 3 constituting the pipe opening 2 of the collective pipe building 1 has a width corresponding to the wall thickness of the side wall 1a. A rectangular cylinder 10 is made of a metal plate of
Mounting hole 11a for fixing a formwork panel (not shown) at the time of concrete casting along the inner periphery of the inner end of the housing.
The inner rectangular frame 11 provided with the above is attached over the entire circumference by welding, and the outer rectangular frame 12 provided with the mounting hole 12a for fixing the hood box 4 is provided along the inner circumference of the outer end of the rectangular cylindrical body 10 over the entire circumference. The flange 13 is attached to the outside of the rectangular cylindrical body 10 by welding over the entire circumference. This flange 13 is to prevent rainwater and the like from entering the collective piping structure 1 from the outside by transmitting between the side wall 1a after the concrete casting and the outer periphery of the rectangular cylindrical body 10.

[0006]

However, in the conventional embedded type penetrating sleeve 3 having such a structure, the wall thickness of the side wall portion 1a of the collective piping building 1 differs from one construction site to another. After receiving the dimensions, the rectangular cylinder 10 must be created with a width that matches the wall thickness. After the rectangular cylinder 10 is created, the inner rectangular frame 11, the outer rectangular frame 12, and the flange 13 are attached. Since it must be done, it takes a long time to create, and the delivery date is delayed.

Further, since the embedded type penetrating sleeve 3 is formed by fixing an inner rectangular frame 11, an outer rectangular frame 12, and a flange 13 each formed of an L-angle to a rectangular cylindrical body 10 formed of an iron plate, the weight is extremely heavy. Transporting to the rooftop of a building is difficult, and especially when the size is large, it cannot be transported by an elevator and must be transported using stairs, which requires a great deal of labor. An object of the present invention is to solve such a problem and to provide an embedded type penetrating sleeve for a building for collective piping which has a short delivery time and is easy to transport.

[0008]

In order to achieve the above object, a buried type penetration sleeve for a building for collective piping according to the present invention is divided into an inner frame (30) and an outer frame (40) which are assembled and joined. The inner frame (30) is formed of a square tubular body (31) and an edge plate integrally protruded inward vertically from the entire circumference of one end of the tubular body (31). 32), and a mounting plate (33) integrally protruding vertically outward from the entire periphery of the end of the cylindrical body (31) opposite to the edge plate (32) and having a plurality of mounting holes (32a). ), Wherein the outer frame (40) is
A quadrangular cylindrical body (41), and a length greater than the attachment plate (33) of the inner frame (30) integrally and vertically outward from the entire circumference of one end of the cylindrical body (41). And a plurality of mounting holes (42) which respectively protrude and correspond to the plurality of mounting holes (33a) of the mounting plate (33) of the inner frame (30).
a flange plate (42) having a) and a bent edge integrally protruded from the entire periphery of the distal end of the flange plate (42) to the side of the outer frame (40) opposite to the cylindrical body (41). Part (43), and an edge plate (44) integrally protruding vertically inward from the entire periphery of the end of the cylindrical body (41) opposite to the flange plate (42). The mounting plate (33) of the frame (30) and the outer frame (4)
0) the flange plate (42) and the mounting holes (33a),
(42a) is butt-connected so as to coincide with each other, and has a thickness adapted to the thickness of the side wall portion of the collective piping building;
The inner frame (30) and the outer frame (40) are combined.

[0009] Thus, the combined thickness of the inner frame and the outer frame matches the thickness of the side wall according to the thickness of the side wall for providing the piping opening of the collective piping structure. With such a choice, even if the thickness of the side wall portion varies from one construction site to another, it can be dealt with immediately and the delivery time can be significantly reduced. In addition, since it is divided into two parts, the weight is reduced and the thickness is reduced, so that it can be easily transported to a building rooftop or the like.

Further, in the present invention, the inner frame 30 has a mounting plate 33 which is integrally and vertically protruded on the entire periphery thereof.
0 has a flange plate 42 integrally and vertically projecting outward from the entire periphery, and furthermore, a bent edge 43 is integrally projected from the entire periphery of the front end of the flange plate 42, The inner frame 30 and the outer frame 40 are bent in the vertical direction, and the mounting plate 33 and the flange plate 42 which are protruded and joined are fixed to each other by a fixing tool, so that the inner frame 30 and the outer frame 40 are transmitted between the outer frame outer periphery and the concrete. The rainwater can be blocked by the flange plate 42 to prevent rainwater from entering the inside of the collective piping structure.

Further, in the present invention, since the bent edge 43 which is bent in the horizontal direction is provided on the entire periphery of the front end of the flange plate 42, the water falling down at the time of placing concrete is prevented from being bent. As a result, it is possible to prevent moisture from entering the inside of the outer frame and the inner frame.
