BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to plastic receivers (eg, nails) installed in formwork of concrete structures. This receiving device is a device for receiving plastic pipes and fittings used for sanitary water and sewage after the concrete of the structure is inserted.

The method used by plumbers to install rainwater drainage pipes, sewer pipes, venting chimney exhaust pipes and plumbing fixtures was costly and inconvenient. In addition, due to the worker's unfaithful work posture, the concrete breakdown of the pipes due to the leakage often occurs.

Conventional methods, in particular field construction methods, generally involve making box-shaped wooden formwork with both sides open. This box is nailed to a formwork of planks before pouring concrete. After curing, the formwork is peeled off, leaving a hole in the plank for the plastic pipes / equipment. Formwork using other shapes and materials than wood boxes is also used to make holes in concrete-based planks. After installing the pipe / equipment, a formwork is prepared to cover the hole passage just below the planks to cover the hole. The formwork is then supported. As a rule, the concrete mortar is mixed by hand, poured into the hole and filled. After curing, the formwork for the hole passages is stripped off and used to flatten the remainder of the ceiling, which has been coated with the anti-corrosive coating.

The installation process is therefore very inconvenient and expensive.

Moreover, debris may fall into the pipe during the painting and bricking, so you must clean it to prevent the pipe system from clogging.

Occasionally, due to unfaithful workers, mortar is of poor quality, perforated and inadequately compressed, causing water to seep through the mortar and flow along the outer surface of the pipe, leaving no adhesion between the pipe and the mortar's flat surface. This leads to corrosion of the reinforcing steel and subsequent breakage of concrete.

The port described later complements and improves the installation of sanitary water pipes and drains / equipment in the following ways.

(a) Since there is no hole to be filled with mortar, which has many holes and lacks adhesion to the pipe, there is no continuous problem of water seeping into the pipe through the mortar.

(b) there is no need for preparation or installation of formwork to leave holes by the use of receivers; There is no need to fill the hole with mortar after installing the pipe / equipment; Prepare the formwork and do not support it directly underneath the concrete slab that covers the hole. As a result, the manpower is saved as a result of the installation of the receiving port and thus labor costs are enjoyed.

(c) The upper end of the receptacle is covered with a removable cover so that debris from broken bricks or hard cement during construction may not fall into the pipe installation.

Hereinafter, an embodiment particularly suitable for the present invention will be described in detail with reference to the accompanying drawings.

A flange 1 having a nail hole 2 for nailing the formwork is formed in the receiver of the present invention. The hollow pipes 3, 4 pass through the flange 1. At the upper end of the hollow pipe 3 is installed a cover 5 which can separate the debris falling into the pipe during construction. Water flows through the pipe 3 to the pipe 4, in order to prevent water leaking along the receiving opening, the inner diameter of the pipe 3 is larger than the outer diameter of the pipe / equipment 6 to be inserted therein and thus The pipe / equipment 6 inserted from the upper end can be fitted into the pipe 3. For the pipe 4, its outer diameter is smaller than the inner diameter of the pipe / plant 7 being inserted, so that the pipe / plant 7 inserted from the bottom can be fitted out of the pipe 4.

When using this receptacle, first align the receptacle and make holes 9 in the wooden formwork (8). Then the hollow pipe 4 is inserted into the hole 9 and the receiver is nailed to the formwork. Concrete structures, ie plates, rafters and columns, are then ready for concrete 10 after connecting the pipes / equipments 6 and 7 to be inserted.

The present invention may be embodied in other forms without changing the features thereof, and the foregoing embodiments are illustrative and not restrictive.

Claims (6)

(a) a hollow pipe having a sanitary water and drainage pipe to be inserted, and then open at both ends to allow drinking water or sewage to flow; (b) a flange having a nail hole for fixing the receiver in the formwork; and (c) the hollow. Receptacle consisting of a detachable cover covering the top of the pipe. The accommodation port of claim 1 wherein the flange is of any shape with no size limitation. The receiver of claim 1, wherein the inner diameter of the upper portion of the hollow pipe is large enough to fit the pipe arrangement to be inserted therein. The receiver of claim 1, wherein the lower portion of the hollow pipe has a sufficiently small outer diameter for the pipe fitting to be inserted to be fitted outside of that portion of the hollow pipe. The accommodation port of claim 1, which is made of a plastic material. Claim 1 described and illustrated with reference to the accompanying drawings.
