Description

[Detailed explanation of the idea]

<Industrial Application Field> The present invention relates to an apparatus for injecting mortar slurry into a mold, and particularly to a vibrating injector having a rod-shaped vibrator and a vibrating plate. <Prior art> As a conventional device or method for injecting this type of mortar slurry, for example, Japanese Patent Application Laid-open No. 1986-
Publication No. 11313 or JP-A-Sho developed by the inventor of this invention
A technique as shown in Japanese Patent No. 60-89305 is known. That is, the former technology is a technology that applies vibration to the injection tube near the injection port outlet or from the mixer to the injection port to degas the trapped air, and the latter technology vibrates the injection device itself to remove the mortar in the injection tube. This is a technology for defoaming the mortar near the injection port. <Problems to be solved by the invention> However, the above-mentioned conventional techniques have the drawback that the device itself is extremely large, or the syringe itself vibrates, resulting in decreased durability due to resonance of the syringe itself, or When the container and the formwork or the injector and the reinforcing bars come into contact with each other, resonance occurs between the two, resulting in misalignment of the reinforcing bars. The syringe according to the present invention is a completely new technology developed in view of these drawbacks of the conventional technology.It is particularly compact as a whole, can be used even in narrow spaces, and can completely eliminate air bubbles generated in mortar slurry. The aim is to provide a completely new injection device capable of foaming and further accelerating the flow of mortar. <Means for Solving the Problems> The present invention involves inserting a part of a rod-shaped vibrator into a mortar retention area, and attaching the rod-shaped vibrator to a predetermined position of a syringe via a cushioning material.
The vibrating injector is characterized in that a vibrating plate is attached to or near the inlet provided at the bottom of the mortar retention box via a cushioning material. <Function> As described above, the injector according to the present invention has a rod-shaped vibrator and a vibrating plate installed in the mortar retention box and at or near the injection port provided in the lower part of the mortar retention box through cushioning materials, respectively. Since it is configured to be installed independently from the syringe body and its accessories, the synergistic effect of the rod-shaped vibrator and the vibrating plate can enhance the defoaming effect of the mortar slurry, without imparting harmful vibrations to the injector body and its accessories. Done,
The mortar slurry flowing out from the retention box is vibrated and flows down along the vibrating plate vibrated by the vibrating motor, thereby being completely defoamed and flowing into the formwork for the ALC board. Furthermore, since a rod-shaped vibrator is inserted into the retention box, clogging of the meshes of the sieve inside the box can be prevented. <Example> To specifically explain an example of the apparatus according to the present invention with reference to figures, in FIGS. 1 to 4, an injection port 2 is provided at the bottom of a mortar retention box 1, and this The inlet 2 is composed of an inlet guide part 3, two vibrating plates 4 provided opposite to the inlet guide part 3, and a packing part 5 for preventing leakage of slurry. These vibration plates 4 have vibration motors 6
are attached to the plate 4, respectively, and the plate 4 is constructed so as to be able to apply vibrations. Also, this vibration plate 4
3 and 4, the fixing bolt 7 is welded to the retention box 1 and the guide 3, and then the ring vibration isolating rubber 8 is coated on the bolt 7. A vibration plate cup 9 coated around this vibration isolating rubber 8 is welded to the plate 4, another vibration isolating rubber 10 is placed on top of the cup 9, and then a ring-shaped holding plate 11, a washer 1
2. By sequentially attaching the fixing nuts 13 to the bolts 7, the vibrating plate 4 is isolated from the surrounding retaining box 1, guide portion 3, etc. and is configured to be independent. Furthermore, a net 15 is inserted and supported within the retention box 1 via a support arm 14. Further, 16 is a guide when fixing to the formwork. Next, 17 is a rod-shaped vibrator, the lower part of which is inserted into the mortar retention box 1. The structure and mounting structure of this rod-shaped vibrator 17 are as shown in FIGS. 1, 3, and 5A and 5B. Fit the anti-vibration rubber 21 into the block plate fixing bolt 20 welded to the box mounting part 19 on the top of the box, fit the integrated base plate 22 and fixing block 23 onto this, and then tighten the block plate fixing nut. 24 can be fixed by screwing into the bolt 20. Fixing block 23
The vibrator 17 can be tightened and fixed using the block fixing bolt 25. In the figure, 26 is a formwork side plate for the ALC board, 27 is its bottom plate, 28 is a reinforcing cage placed on the formwork bottom plate 27, and 29 is a ring-shaped rubber stopper provided around the lower part of the vibrator 17. When using the device according to the present invention, the device of the present invention such as the retention box 1 is fixed to the side plate 26 of the formwork for the ALC board using the guide 16, and the mortar slurry flowing out from the mixer (not shown) is fixed. The mortar slurry that flows into the net 15 of the retention box 1 and flows down through the inlet 2 after flowing into the retention box 1 is almost completely removed by the vibration action of the rod-shaped vibrator 17 and the vibrating plate 4. The ALC is poured into the formwork while being degassed, and the ALC as shown in Figure 6 is formed in the formwork.
A plate 30 can be formed. ALC board 30 manufactured using the device of the present invention
500
The number of bubbles with an area of mm was investigated with and without vibration, and the results shown in Table 1 below were obtained.

[Table] <Effects of the invention> Since the device according to the invention has the structure and function as described above, the whole device is compact and can be easily attached to a mold for use, and the injection port is formed in a slit shape. Therefore, it can be injected even in narrow spaces, and since a rod-shaped vibrator or vibrating plate is installed in the mortar retention box and a part of the injection port at the bottom, the slurry flowing down is reliably degassed by vibration. In addition, the rod-shaped vibrator and the vibrating plate can each vibrate independently through the cushioning material, and there is no resonance of the syringe itself, making it possible to obtain a defoaming attachment with excellent durability. The rebar cage will not vibrate due to resonance of the formwork, etc., and since a part of the injection port is formed by a vibrating plate, it is possible to accelerate the flow of mortar slurry, and the action of the rod-shaped vibrator makes it possible to prevent the rebar cage from vibrating. With a simple structure, it is possible to obtain an excellent defoaming device that can prevent clogging and can also be used in a flat formwork with a low height.
