Problems solved by technology

Meanwhile, due to other work such as carpentry work, once the wood hits the plug protruding outward, the plug 102 and the piping material 103 will be damaged.
[0011] In addition, sometimes the plug-in 102 is removed and left for a few days. At this time, sand and the like may enter the inside of the pipe 103.

no. 1 Embodiment approach

[0057] figure 1 It is a left view, a front view and a sectional view of this embodiment.

[0058] Such as figure 1 As shown, the overall shape of the piping insert TP1 is substantially cylindrical, and is composed of a main body 10 and an internal thread portion 20 .

[0059] On the outer circumference of the body 10 with a diameter of about 7 mm, there is a right-handed external thread 11, and on the left half of the inner circumference, there is a hexagonal wrench hole 12 as a rotatable dismounting device. Insert the fixing bolt 40 (below, refer to figure 2 ) metal sleeve 13, which has a right-handed internal thread 13a on the inner peripheral surface of the metal sleeve 13.

[0060] The main body 10 and the internal thread part 20 are integrally made, and the material is preferably plastic (synthetic resin), casting, iron, brass, copper-tin alloy, zinc and the like.

[0061] Below, refer to figure 2(A) to (C) The use of the plug TP1 of this embodiment and the press...

no. 2 Embodiment approach

[0072] image 3 It is a left view, a front view and a sectional view of this embodiment.

[0073] The difference between this embodiment and the first embodiment is that the right end of the internal thread portion 20 of the first embodiment is sealed (refer to figure 1 sectional view, the first embodiment is referred to as "sealed type"); and the right end of the internal thread portion 20A of this embodiment is open (refer to image 3 sectional view, the second embodiment is referred to as "through type").

[0074] Such as image 3 As shown, at the right end of the internal thread portion 20A, an elongated through hole 21 through which the fixing bolt 40A can pass is formed. Except for the through-hole 21, other configurations are the same as those of the first embodiment.

[0075] Below, refer to Figure 4 , while describing the use of the plug-in TP2 of this embodiment and the pressure test during piping work.

[0076] first as Figure 4 As shown in (A), a temporar...

no. 3 Embodiment approach

[0107] Figure 10 Shown is a cross-sectional view of the L-shaped joint JL of the present embodiment.

[0108] The cylindrical L-shaped joint JL is provided with a protruding bolt seat 60 at the vertex on the extension line of the center line of the pipe portion 63 on the side where the internal thread 62 is formed at the opening.

[0109] The internal thread 61 is provided on the inner surface of the bolt seat 60, and the center line thereof coincides with the center line of the pipe 63 described above. 64 is another pipe.

[0110] Below, refer to Figure 11 (A) to (C), the piping work and the pressure test performed using the L-shaped joint JL of this embodiment will be described.

[0111] first as Figure 11 As shown in (A), the other tube 64 of the L-shaped joint JL is respectively fixed to the upper and lower ends of the piping material 103 .

[0112] Then if Figure 11 As shown in (B), a temporary frame 101 with a hole 101a with a diameter of about 7mm that allows th...

Abstract

Provided is a plug for testing of piping work which is not destroyed even if it is kept to be screwed into the water supply piping, and performs a hydraulic test, while cement is tamped down by fixing a temporary frame and water supply piping, in the case of the water supply piping work such as the concrete wall of the building. A male screw (right-hand thread) screwing the screw inserted part of the piping member prepared in advance is provided on an outer peripheral surface of the plug body (body part 10) for testing the piping work, and a female screw (right-hand internal thread 13a) screwing a bolt from the outside is provided in the plug body for the testing. The plug body for testing is equipped with a rotating removal means (hexagon wrench socket 12) for removing the plug for testing by rotating it after the screw inserted part is sealed with the plug for testing and the concrete is placed.

Description

technical field [0001] The present invention relates to an insert for piping work, and particularly relates to a water supply piping construction on a concrete wall of a building, in which the temporary frame and the water supply piping can be firmly fixed before cement pouring, and even if it is screwed into the water supply piping and left idle It is also an insert for piping work that can be hydrostatically tested without being damaged. Background technique [0002] For example, it is sometimes necessary to bury piping materials such as faucet elbows on the concrete walls of buildings. At this time, it is necessary to pour concrete while the piping material is fixed by a temporary frame such as a plate, and after a predetermined period of time, remove the temporary frame and conduct a leak test (pressure test). [0003] In the past, when pouring concrete, first such as Figure 9 As shown in (A), after the temporary frame 101 made of plywood is assembled, the pressure tes...
