Description

  This invention relates to a joint used when a U-shaped groove formed by concrete molding is provided on a new concrete floor and a drain pipe from a sink such as a kitchen is connected thereto.

  When a concrete floor such as a new building is provided with a U-shaped groove by concrete molding and a drain pipe from a sink such as a kitchen is connected to it, the drain pipe is first attached to the wooden formwork that forms the U-shaped groove. The work is conventionally done by cutting the existing pipe material into an appropriate length on site by the operator to create a drain pipe member, and the end of the drain pipe member is attached to the U-shaped groove formwork. Then, it was temporarily fixed with adhesive tape, nails, etc., and then green concrete was driven around it. However, all of these temporary fixing operations require skill for manual operations. In the case of unskilled workers, the wooden formwork forming the U-shaped groove and the mutual fixing of the end portions of the drainage pipe members are connected to the connecting portion. When the concrete is driven in the temporarily fixed connection state, the concrete flows into the drain pipe or the height at which the drain pipe is connected is shifted. Therefore, it was a difficult task for construction personnel.

  In view of the above circumstances, when the drainage pipe is connected to a concrete formwork such as a U-shaped groove, when the concrete is driven in the temporarily fixed connection state, the concrete flows into the drainage pipe unexpectedly, In order to prevent deviations in the height at which the pipes are connected, a joint with a standardized structure that connects the drain pipes in advance is used, so that the work can be done without requiring skill. The purpose is to shorten and improve the efficiency, and to contribute to the efficiency and economic efficiency of the entire construction.

  The end of the base tube (4) is formed so as to form a 45 ° slope, and a collar piece (5) having an appropriate shape and configuration is formed on the periphery of the base tube (4). A socket for connecting a drain pipe to a concrete formwork such as a U-shaped groove characterized by comprising a socket with a plate (3) and a nipple with a plate (3a), facing the end of the base pipe (4 ') A flange portion (5 ') having an appropriate shape and configuration is formed on the periphery, and a socket with a plate (3') integrally formed of synthetic resin and a nipple with a plate (3a ') As a joint for connecting a drain pipe to a concrete formwork such as a U-shaped groove, the U-shaped connecting the drain pipe (2) from the kitchen sink (A) to the floor (F), for example When the groove (U) is provided, it is discharged into the concrete formwork (1). When the pipe (2) is connected in a temporarily fixed state and ready-mixed concrete is driven around these, the above-mentioned standard socket with a plate (1) connected to the concrete formwork (1) at the tip of the drain pipe (2) 3), (3 '), nipple with plate (3a), (3a') is used as a joint. This prevents the concrete from flowing into the drain pipe (2) unexpectedly when the concrete is driven in a temporarily fixed connection state, or the height at which the drain pipe (2) is connected is displaced. Work is possible without the need.

  When connecting the drainage pipe to the U-shaped groove, the joint of this device may cause the concrete to flow into the drainage pipe unexpectedly, or the height at which the drainage pipe is connected may shift. It is a joint with a standardized structure that connects the drain pipes in advance to prevent it from happening, so that it can be operated without requiring skill, shortening the work period and improving efficiency, It can contribute to efficiency and economy. The standardized joint used here is manufactured in advance, and the use of the joint makes it extremely convenient for work.

  The end of the base tube (4) is formed so as to form a 45 ° slope, and a collar piece (5) having an appropriate shape and configuration is formed on the periphery of the base tube (4). A socket with a plate (3), a nipple (3 ') with a plate, a joint for drainage pipe connection to a concrete formwork such as a U-shaped groove, the end of the base pipe (4') is A flanged piece (5 ') having an appropriate shape and configuration is formed on the periphery, and a socket with a plate (3a) integrally formed of synthetic resin and a nipple with a plate (3a' Is a joint for connecting a drainage pipe to a concrete formwork such as a U-shaped groove, characterized in that a mounting hole (6) is provided in the collar piece (5), (5 '). Drain pipe to concrete formwork (1) placed prior to forming groove (U) When connecting 2), these sockets with plates (3), (3 ') and nipples with plates (3a), (3a') are attached to the concrete formwork (1). 5) Insert a nail into the mounting hole (6) in (5 ') and fix it. And by attaching the drainage pipe (2) cut out to this, they can be joined efficiently. As a result, the concrete formwork (1) is connected to the concrete formwork (1) in a temporarily fixed state, and the ready-mixed concrete is driven into the periphery of the concrete formwork. The process and work can be operated without requiring skill, shortening the work period, increasing efficiency, improving the efficiency of the entire work, and economic efficiency. Can contribute.

  FIG. 1 shows that when a kitchen is installed in a newly-built building or store, a U-shaped groove (U) formed by concrete molding is provided on the floor (F), and a kitchen sink (A The state which connects the drain pipe (2) from) is shown. In this way, the waste water from the sink (A) flows through the drain pipe (2) and flows into the U-shaped groove (U) which is a drain groove. Here, (G) is a lid (grating) of the U-shaped groove (U). Fig.2 (a) is a detailed figure in the case of construction, and shows the state by which a drain pipe (2) is connected to the concrete formwork (1) arrange | positioned prior to forming a U-shaped groove (U). An oblique contact state with respect to the U-shaped groove (U) when the drain pipe (2) is bent in the middle and a direct connection state when the drain pipe (2) is straight are shown. FIG. 2B is a side cross-sectional view of FIG. Here, when connecting the drain pipe (2) to the concrete formwork (1) arranged prior to forming the U-shaped groove (U), the drain pipe (2) is temporarily fixed to the concrete formwork (1). Connected in a state, and when ready concrete is driven around, prevent the ready-mixed concrete from flowing into the drain pipe (2) and the height of the connected drain pipe (2) from being displaced. In addition, as a joint with a standardized structure, which is connected to the concrete formwork (1) to which the drain pipe (2) is connected in advance, sockets with plates (3), (3 ′), nipples with plates (3a), (3a ') And so on there.

  FIGS. 3 (a), (b), and (c) are views seen from three sides of the socket (3) with a plate for oblique connection, and the end of the base tube (4) is a 45 ° slope. And a flange piece [this configuration is not necessarily shown in the figure, for example, a shape / configuration that is partially cut off] (5) is formed on the periphery. Made of resin (vinyl chloride resin, etc.) and integrally molded. In addition, the base pipe part (4a) is a part which inserts the pipe material of the drain pipe (2) prepared by cutting, and attaches it inside, FIG. 4 (a), (b), (c) is FIG. 3 (a). , (B), (c) is a joint used when the pipe of the drainage pipe (2) is covered from the outside as the base pipe part (4) only, without providing the base pipe part (4a). This is referred to as (with seat) or nipple with plate (3a). These flange parts (5) are provided with several mounting holes (6).
