Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive injector for embedding and fixing an anchor for fixing a mating member to a surface of a structure, and in particular, to an adhesive. The present invention relates to an injector suitable for a small-diameter embedding hole. 2. Description of the Related Art It is widely practiced to fix counterpart materials such as equipment and interior materials to the surface of an existing structure made of a plastic material such as concrete, brick and stone by screwing. Drilling holes in the structure, injecting synthetic resin adhesive, embedding anchors generally consisting of bolts, waiting for the adhesive to harden, placing the mating material on the surface of the structure and screwing it into the anchor It is fixed with a nut. [0003] The adhesive is composed of a synthetic resin as a main agent and a curing agent thereof, and is used in such a manner that when these are mixed and left to cure over time, the main agent and the curing agent are easily broken. Enclose it in a container and mix it in the embedding hole,
Alternatively, in addition to the means of injecting a mixture of these into the embedding hole from a cup-shaped container, the main agent and the curing agent are simultaneously extruded at a predetermined ratio from the respective containers, mixed by a mixer and mixed into the embedding hole. It is known to use an injector adapted for injection (Japanese Patent Application Laid-Open No. 53-12128,
See Japanese Utility Model Laid-Open No. 55-9256). [0004] The injector described in the above publication has a container for separately loading a main agent and a curing agent, an extrusion mechanism for simultaneously extruding these at a predetermined ratio, and mixing the extruded main agent and the curing agent. The mixer comprises a mixer composed of a static mixer and an injection nozzle for injecting an adhesive as a mixture into the embedding hole. The injection nozzle is screw-connected to a tip of the mixer. For this reason, the adhesive is reliably injected from the injection nozzle into the small-diameter embedding hole without spilling around.
For a large-diameter embedding hole, it is possible to remove the injection nozzle and inject a large amount of adhesive in a short time while reducing the flow resistance. However, the mixer and the injection nozzle of the conventional injector are both made of metal, and the male screw provided at the distal end of the housing of the mixer and the screw provided at the proximal end of the injection nozzle engage with the screw. When the injection nozzle is removed and the adhesive is extruded and injected, if the adhesive adheres to the external thread, the injection nozzle may not be able to be screwed in. Once hardened, removal becomes impossible. Therefore,
The actual pouring operation is performed with the pouring nozzle attached regardless of the diameter of the embedding hole, and there is a problem that the working efficiency for the large-diameter embedding hole is poor. Further, since the mixer and the injection nozzle are used repeatedly, it is necessary to remove these residual mixtures after use, but it is extremely difficult to remove the mixer depending on the structure. [0006] The problem to be solved by the present invention is that the mixer and the injection nozzle are connected by a screw connection by meshing a male screw and a female screw provided in advance. When the adhesive is directly removed from the mixer by removing the injection nozzle and having the conventional injector, the injection nozzle may not be able to be reconnected, and therefore the adhesive may be removed from the injection nozzle regardless of the size of the embedding hole. Work efficiency for large-diameter embedding holes is not good,
That is the point. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a cylinder container in which a main agent of an adhesive and a curing agent are separately charged, and a cylinder container which is charged from a base end into each cylinder container. An extrusion mechanism that has a piston and simultaneously extrudes the main agent and the curing agent at a predetermined ratio, a mixer that communicates with each cylinder container and is connected to their ends, and a nozzle tube that is connected to the end of the mixer becomes, mixer multiple twisted plate member sequentially phase shifting by der I cylinder container that incorporates a tubular housing made of aligned rigid synthetic resin in a row

Reference numerals 1 and 2 denote a cylinder container, 11 denotes an extrusion mechanism, 21 denotes a mixer, 31 denotes a nozzle tube, and two cylinders. The containers 1 and 2 have a predetermined cross-sectional area ratio and are arranged substantially adjacent to and parallel to each other. One of the containers is filled with a liquid synthetic resin such as an epoxy resin as a main agent, and the other is a curing agent such as a modified fat. A group polyamine is loaded. The cylinder containers 1 and 2 are made of a hard synthetic resin integrally formed with a flange 3 at the base end, a connecting piece 4 at the middle, and a nozzle 5 at the tip. A screw 6 is provided on the outer peripheral surface of the nozzle 5. Have been. The pushing mechanism 11 has two pistons 12, 1
4 and piston rods 13 and 15 extending therefrom, a plate-shaped mounting member 16 through which the piston rods 13 and 15 are slidably penetrated, and a plate-shaped pressing body 1 fixed to their base ends.
The scale 18 is provided on one of the piston rods 13. The pushing mechanism 11 includes pistons 12 and 14
From the base end into the cylinder containers 1 and 2 and
Is mounted on the cylinder containers 1 and 2 by engaging the hooks 19 with the flange 3 and manually pushing the pressing body 17 to simultaneously drive the pistons 12 and 14 in the distal direction at the same speed. The main agent and the curing agent are extruded and joined to the nozzle 5 at the tip at a flow rate equal to the cross-sectional area ratio of the cylinder containers 1 and 2. The flow rate, that is, the amount of the adhesive to be injected into one embedding hole is determined by visually checking the scale 18 and pressing the pressing body 1.
Press 7 to know exactly. The mixer 21 has a plurality of twisted plate members 22 having a 180-degree twist and forming a helical passage arranged in a line while sequentially shifting the phase by 180 degrees so that their edges are in contact with each other. 23, and details thereof are described in US Pat. No. 3,286,9
No. 92. The housing 23 has a stepped portion 24 having the same diameter as the nozzle 5 but gradually becoming smaller in diameter at the tip thereof.
Is made of hard synthetic resin. The mixer 21 is connected to the tips of the cylinder containers 1 and 2 in a state where the nut 26 fitted on the housing 23 is screwed onto the nozzle 5 so as to overlap the nozzle 5, and is extruded from the nozzle 5. The main agent and the curing agent introduced into 23 are divided into two each time they pass through the twisted plate member 22 and mixed each time to finally prepare an almost uniform mixed state adhesive without power. The nozzle tube 31 is made of metal, has a female screw 33 in the enlarged portion 32 at the base end, and has an axial groove 34 formed across the female screw 33. The nozzle tube 31 is formed by connecting the enlarged portion 32 to the step portion 24.
The female screw 33 is screwed into the step part 24 as it is while being threaded by being pushed in while being rotated and connected to the mixer 21, and the groove 34 is used for cutting chips generated at the time of threading. Discharge and screw with a small force. From this, it is clear that the female screw 33 is a tapping screw. Further, the nozzle tube 31 is made smaller in diameter than the step portion 24 and can be easily inserted into the small-diameter embedding hole, so that the adhesive can be injected without spilling around. When the main agent and the curing agent in the cylinder containers 1 and 2 are completely extruded, the extruding mechanism 11 and the mixer 21 are removed from the cylinder containers 1 and 2 and the new cylinder containers 1 and 2 are removed.
And continue the adhesive injection work. Therefore, a plurality of the cylinder containers 1 and 2 loaded with the main agent and the curing agent can be prepared and used as a cartridge. In addition, since the mixer 21 can be removed from the cylinder containers 1 and 2, the mixture of the main agent and the hardener remaining and filled after the operation is completed can be removed before the hardening starts. In this case, since the inside of the mixer 21 has a simple structure in which the twisted plate members 22 are arranged in a line, the removal is easy. However, in the present embodiment makes torsion plate member 22, a housing 23 of a hard synthetic resin, in particular ahead of the housing 23
The end is threaded to connect the nozzle tube 31
And the mixer 21 is inexpensive, so economical
In Ru can be disposable without causing a disadvantage. Further, since the nozzle tube 31 can be removed from the mixer 21, when it is injected into a large-diameter embedding hole, it is removed to reduce the flow resistance, and a large amount of adhesive can be supplied in a short time. It can be used properly depending on the diameter of the embedding hole, for example, by injecting. At this time, the tip of the housing 23 is
Low discharge resistance due to male thread formed instead of thread
And a large amount of adhesive can be discharged in a short time. In addition,
In this case, even if the adhesive adheres to the outer peripheral portion of the tip of the housing 23, the female thread 33 is threaded so that the nozzle tube 3
1 can be reliably reconnected to the mixer 21. It should be noted that three cylinder containers 1 and 2 are used depending on the mixing ratio of the main agent and the curing agent, and the number is not limited to two. For example, two of the cylinder containers are charged with the main agent and one is charged with the curing agent. It is. The push-out mechanism 11 includes the piston rod 1.
An appropriate device using a manual force can be used, such as using a lever to convert the turning power into an extruding force without directly pressing the 3, 15. According to the present invention, the main agent and the curing agent are charged in separate cylinder containers in a state of being separated from each other, and are extruded by an extruding mechanism so as to correspond to the sectional area ratio or the number ratio of the cylinder containers. Since it extrudes into a mixer at a ratio and mixes without power and injects it into the embedding hole from the nozzle tube, it is possible to always inject an adhesive consisting of a predetermined ratio of the mixture without skill at places where power is not available Things. In particular, according to the invention, the nozzle tube is threaded on its proximal female thread.
Detachable screw connection to mixer housing tip
The cutting chips are discharged from the grooves at this time.
With small force and cutting chips inside the housing and nozzle tube
The thread can be cut without worrying about entering the department. Also,
The mixer must be threaded for nozzle pipe connection.
Because it is unnecessary, disposable without economical disadvantage
Can be used. Furthermore, with respect to the small diameter buried holes eliminate worries spilling injected from the nozzle tube, ejection by screws from the mixer to remove the nozzle pipe for embedding hole of the large-diameter
Improve work efficiency by injecting directly without receiving resistance ,
Not only can it be used properly, but even if adhesive adheres to the outer periphery of the tip when directly injected from the mixer, the nozzle tube can be securely reconnected and further removed, and the site where large and small embedding holes are mixed It is convenient to work with.
