In addition, in the present invention, the flange (2 0 a) (2 0 b), the mounting piece (3 0 a) (3 0 b) and the holding piece (4 0 a) (4 0 b) can be formed into each other as It may be formed as one body, or separately formed by another hip. (Please read the precautions on the back and fill in this page)-Packing and Ordering Oxygen Printing of the Beigong Consumer Cooperative of the Central Bureau of Economics and Trade [Effect of Invention] As mentioned above, according to the mold of the present invention, a pair of clamping pipes can be arranged The collar halves are connected to each other by the front ends of the connecting device pieces, and are used on the piping. Therefore, half of the areas in the outer circumference of the pipe can be arranged in the remaining half of the inner edge of the seal. The piping is provided. The annular gap between the surfaces of the floor mortar and the resin-made shaft connection can be free. This can be fixed on both sides so that one side is at the same time. Therefore, the mortar through the side of the floor slab can be used to ensure that the ring half of the tube hole is separated from the elastically supported sand. The other side is perforated with two axes to prevent the circumference of the sand bearing ring half body that is tightly held on both sides in the state of the mortar The garden surface mortar is filled with a single hug and fixed at the edge of the pulp flange and the pipe is filled with a ring-coating paper. The standard is China National Standard (CNS &gt; A4 specification (210X297 mm) -18 Ministry of Economic Affairs Employee's consumption cooperation of the Central Central Bureau of Administration, Du Printed A7 _ B7 V. Description of the invention (16) The mortar in the shape of the gap hangs down to the lower layer. The piping is clamped from both sides and only a pair of collars are combined by the coupling device. The body can be simply attached to the pipe. The material is made of resin, in addition to being light in weight, and can be given appropriate softness to effectively prevent damage to the pipe. In addition, once the mortar is hardened, it can be released by the connecting device The two collar half bodies can be detached from the pipe in the original state after being connected, so it can be reused many times, and can be effectively formed by resin molding, which can not only reduce manufacturing costs but also be economical The surface is extremely favorable. Moreover, the lower side of the mortar after hardening can obtain a smooth and good processing state by the top connection of the flat upper surfaces of the two flanges. In the present invention, if it is formed on the lower side of the outer periphery of the mortar bearing flange The trough for truncation has the advantage of interfering with the peripheral edge of the mortar flange on the peripheral members such as adjacent pipes, which interferes with the installation of the mold, and causes the flange to bend at the trough for truncation It can be cut off to cut off the peripheral edge of the position where it interferes with the surrounding members. Therefore, for example, when a plurality of pipes are arranged in a dense state, there is an advantage that the mold can be reliably installed. As described above, when the protrusion is provided with an elastic restraining piece, the elastic restraining piece is closely attached to the peripheral surface of the pipe, so that the gap between the pipe and the peripheral surface in the flange can be surely blocked, and the mortar can be more reliably prevented from drooping. At the same time, it can improve the installation strength of the piping, and it has the advantage of reliably preventing the mold from deviating and falling off. Moreover, the above-mentioned elastic restraining piece is composed of many elongated flat protrusions ~ At the time of installation, the slender and flat protrusions of the mold's piping are properly flexed and tightly connected, so that the installation piece can be used across the circumference of the pipe.
