Abstract

(57) [Summary] [PROBLEMS] Conventionally, a grout material has been press-fitted from a pipe or a hose after temporarily inserting a pipe or a hose into a mold form into which mortar is injected and temporarily fixing it with quick setting cement or the like. However, there is a problem that the pumping hose is easily pulled out due to the weight of the pressure feeding hose and is unstable, and it is necessary for an operator to manually hold the hose so as not to be pulled out. SOLUTION: An inlet main body 2, which is constituted by a pipe 2A, a flange 2B which is continuously provided outward in a flange shape around an inner end of the pipe 2A, a connecting hose 3, and a fastener for bending the hose. With the grout inlet composed of 4
Connect the inlet body and connecting hose to the formwork securely.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a grout inlet having a novel configuration.

[0002]

[Prior art]

 Conventionally, this type is as follows. A pipe or hose 10 was inserted into a mold 5 into which mortar was injected, temporarily fixed with a quick setting cement 10A or the like, and then grout material 10B was press-fitted by a grout pump connected to the pipe or hose.

[0003]

[Problems to be solved by the invention]

 The technology described in the prior art has the following problems. 1. Since the pumping hose is easily released due to the weight, unbalanced load and injection pressure of the pumping hose, it is necessary for the worker to support the pipe or hose by hand so that the pipe or hose does not come off from the formwork when grouting. 2. Since a sufficient injection pressure cannot be applied to the grout material, for example, referring to FIG. 6, the contact corner 10C1 between the tip 10C of the pipe or hose 10 and the inside of the mold 5 cannot be reliably filled. 3. As shown in FIG. 7, the tip of the pipe or hose is cut off when the form is removed, so that the tip 10C of the pipe or hose 10, which is a foreign substance, remains in the injected grout material 10B.

[0004] The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a solution that can solve the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, the device of the present invention comprises an inlet main body 2, a connecting hose 3, and a fastener 4 for bending the hose, and the inlet main body 2 is a pipe 2A of a predetermined size made of a metal material such as stainless steel. And a flange 2B continuously connected outward in a flange shape around the inner end of the pipe 2A, and the connecting hose 3 is formed of a hose 3A of a predetermined size formed with a bendable blade hose. The hose 4 is detachably mounted so as to cover the outer peripheral surface of the pipe 2A of the inlet main body 2, and the hose-bending fastener 4 is a grout inlet formed by cutting a wire into a predetermined length. is there.

In this case, the following configuration can be adopted. The band 4A used in place of the hose-bending fastener 4 is formed of a stretchable synthetic resin material into a ring shape having a predetermined size.

The present invention is used as follows. 1. When the mold 5 is attached, an insertion hole 5A corresponding to the diameter of the pipe 2A in the inlet body 2 is opened in a part of the mold 5 and the pipe of the inlet body 2 is inserted into the insertion hole 5A from inside the mold 5. 2A, the flange 2B of the inlet main body 2 is brought into contact with the inner surface of the mold 5 and the tip of the connecting hose 3 inserted into the pipe 2A of the inlet main body 2 is attached to the outer surface of the mold 5. Abut. In general, an air vent hose 5B is attached or an air vent hole (not shown) is formed at the uppermost position of the mold 5 from the position where the pipe 2A is inserted. 2. A grout pump side hose 8 from a grout pump 7 is connected to the connection hose 3 via a valve 6. 3. After injecting the grout material 9B, the connecting hose is bent, and the bent portion is tightened with the hose bending tool 4 or the band 4A, and the grout pump side hose 8 is pulled out while the injection pressure is applied. . 4. The injection is confirmed by leaking the grout material from the air release hose or air release hole, or by using a known pressure gauge 9.

[0008]

[Embodiment of the invention]

 Embodiments will be described with reference to the drawings. Reference numeral 1 denotes a grout inlet of the present invention, which comprises an inlet main body 2, a connecting hose 3, and a fastener 4 for bending the hose. 4A is a band that can be used in place of the fastener 4 after the hose is bent. A. The inlet main body 2 includes a pipe 2A having a predetermined dimension made of a metal material such as stainless steel, a flange 2B continuously connected outward in a flange shape around an inner end of the pipe 2A, and an outer peripheral surface of the pipe 2A. Is formed from the tapered surface 2A1 formed on the outer portion of the above. B. The connecting hose 3 is constituted by a hose 3A of a predetermined size formed by a bendable blade hose, and is detachably mounted so as to cover the outer peripheral surface of the pipe 2A of the inlet main body 2. C. The fastener 4 for bending a hose is formed by cutting a number line to a predetermined length. The band 4A is made of a stretchable synthetic resin material and has a ring shape having a predetermined size.

【Example】

 Furthermore, as a result of conducting an experiment under the following conditions, extremely good results were obtained. Dimensionally, the following condition was suitable. A. About the inlet body 2 a. B. Diameter of pipe 2A to outer diameter of about 25 mm to 45 mm About connecting hose 3 a. Inner diameter of hose 3A to about 25 mm to 45 mm b. Hose 3A length ~ 300mm

[0010]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. 1. When attaching the injection port main body 2 to the insertion hole 5A of the mold 5, after inserting the pipe 2A of the injection port main body 2 into the insertion hole 5A, the flange 2B of the injection port main body 2 is brought into contact with the inner surface of the mold 5. At the same time, the tip of the connecting hose 3 inserted into the pipe 2A of the inlet body 2 can be brought into contact with the outer surface of the mold 5 so that the pipe or hose does not come off the mold when grout is injected. There is no need for workers to support them by hand. 2. It is not necessary to insert a pipe or a hose 10 into the mold 5 and temporarily fix it with the quick-setting cement 10A or the like, as in the related art. 3. When the injection port main body 2 is attached to the insertion hole 5A of the mold 5, after the pipe 2A of the injection port main body 2 is inserted into the insertion hole 5A, the pipe 2A does not protrude into the mold. The grout material can be sufficiently injected evenly. 4. When the mold is removed, the injection port body 2 can be removed together with the mold, so that no foreign matter remains in the injected structure as in the related art. 5. In addition, it has the effects of being inexpensive to manufacture, easy to assemble due to the small number of parts, and economical.
