Here, rotating rings 11a and 12a are formed at upper ends of the first fixing part 11 and the second fixing part 12 so as to be fitted to the central shaft 13 and then rotatably coupled.

Here, the locking groove 11b is formed in the end portion of the first fixing portion 11 sequentially along the outer surface, and the locking groove 11b is selectively fixed to the locking portion 11b at the end portion of the second fixing portion 12. It is preferable that the locking projections 12b be formed. That is, the locking projection 12b of the second fixing part is selectively coupled to the locking groove 11b of the first fixing part, and the fixing member forms a circle according to the diameter of the sleeve S to support the sleeve S. It is configured to. Therefore, since the diameter of the fixing member 10 for fixing the sleeve S is changed according to the diameter of the sleeve S, the fixing member 10 can be used to fix the sleeve S having a different diameter interchangeably. do.

Next, the support bar 20 is a portion for supporting the upper side of the fixing member 10, the lower end is coupled to the central portion of the central axis 13 is formed extending upward. That is, the support bar 20 is a portion supporting the upper side of the fixing member 10 so that the sleeve (S) can be installed at a constant height in the downward direction from the top of the formwork.

Next, the fixing bar 30 is configured such that one end is coupled to the upper end of the support bar 20 and the other end is fixed to the upper surface of the formwork (1). That is, the fixing bar 30 fixes the upper end of the support bar 20 to the upper surface of the formwork 1 so that the sleeve S can be installed at a constant height downward from the upper end of the formwork 1. It is a part for fixing the support bar 20.

On the other hand, the present invention is configured to be easily installed in the desired position by adjusting the position of the sleeve (S) installed in the formwork (1). To this end, the support bar 20 is formed at the lower end of the fixing ring portion 21 is fitted to be coupled to the outer surface of the central shaft 13, a plurality of height adjustment slits 22 are formed in the upper and lower directions sequentially. The fixing bar 30 has a fixing hole 31 into which a nail A inserted into the upper surface of the formwork 1 is inserted at one end, and a plurality of fixing slits 32 are sequentially formed in the left and right directions at the other end. It is formed so that the end thereof is selectively fitted to the height adjustment slit 22 and then fixed to the support bar 20 by pins P selectively fitted to the fixed slit 32.

That is, the fixing bar 30 is configured to be fixed to the formwork 1 by inserting the nail A into the fixing hole 31 formed at one end thereof and being fixed to the upper surface of the formwork 1. The other end is selectively fitted to the height adjustment slit 22 formed at the upper end of the support bar 20 is configured to be installed while adjusting the height of the sleeve (S) in the formwork (1). The other end of the fixing bar 30 is fitted to the height adjusting slit 22, and the pin P is selectively inserted into the fixing slit 32 from the outside of the supporting bar 20 to the fixing bar 30.

Next, the fixing nail 40 is inserted through the central axis 13 and fixed to the formwork 1 is configured to support and fix the central axis 13 to the formwork 1. That is, the fixing nail 40 penetrates the inside of the central shaft 13 and the end thereof is fixed to the inside of the formwork 1 so that the fixing member 10 coupled to the central shaft 13 is formed by the formwork 1. It is configured to be firmly supported on the inside. Therefore, the fixing member 10 fixed through the fixing nail 40 when the concrete (C) is poured into the formwork to form a wall through the formwork (1), the sled portion (S) fixed to the fixing member (S) ) Do not move or twist in place due to the load of the concrete.

Finally, the lid 50 is configured to seal both ends of the sleeve is installed in the fixing member. That is, the lid 50 serves to prevent concrete from flowing into the sleeve S when the sleeve S is installed. And the lid 50 is configured to be separated from the slip part (S) by tapping with a finger when the concrete construction is finished.

In particular, it is important that the lid completely seals both ends of the sleeve so that water or concrete does not flow into the sleeve during concrete pouring. To this end, the lid 50 is preferably composed of BWS (Bentonite Water Stop, Bentonite Water Expansion Index). Here, the BWS can be used to be processed to a certain dimension by compressing the high-expansion sodium bentonite of 16 times the volume when contacted with water and then close the circumferential surface with a mesh.

This BWS enhances the sealing property at the interface due to its unique hydration expansion ability, for example, it rapidly expands upon contact with water and maintains perfect sealing property. Furthermore, if the cracks or voids formed at the interface of the sleeve while performing the primary exponential function by hydration expansion, the self-sealing function is implemented to seal and fill the cracks and voids.

In addition, in the case of the lid 50, the sodium bentonite to be molded has a caking point without changing the chemical properties, so 7.5% by weight of chloroprene rubber in sodium bentonite to increase the ductility, durability and compression deformation, trans 2.5% by weight of -1,2-ethylene dicarboxylic acid, 2.5% by weight of poly amide-amine and 2.5% by weight of cellulose diacetate may be further mixed and molded.

At this time, the chloroprene rubber is a hydrophilic polymer to improve the moldability while improving the deformability during compression, there is an elastic force to prevent the break during deformation to enhance the perfect sealing function.

In addition, trans-1,2-ethylene dicarboxylic acid (C ₄ H ₄ O ₄ ) is characterized by preventing particle entanglement, imparting dispersion stability, and improving tensile strength and flexural strength to facilitate compressive deformation. have.

In addition, the polyamide amine is added because it has an advantageous function to enhance the index function while maintaining heat resistance and cold resistance.

In addition, since cellulose diacetate has a high glass transition temperature due to the pyranose ring constituting the cellulose, it is added to improve tensile strength, flexural strength, and impact strength.

In order to confirm the index characteristics of the lid 50 in the sleeve as described above, the lid was bonded to the actual sleeve and immersed in the water tank while the sleeve was sealed. And it left to stand for 5 days in this state for a water tightness test. After 5 days, it was checked whether a leak occurred inside the sleeve. As a result of visual inspection, it was confirmed that no immersion occurred inside the sleeve. Through this, it was confirmed that the index characteristic is excellent.

The through sleeve fixing device for the wall retaining wall according to the present invention configured as described above, as shown in FIG. 5, rotates the first fixing part 11 and the second fixing part 12 based on the central axis 13, The locking protrusion 12b of the second fixing part is selectively coupled to the locking groove 11b of the first fixing part so that the fixing member has a circular shape to support the sleeve S according to the diameter of the sleeve S. . At this time, because the diameter of the fixing member 10 for fixing the sleeve (S) according to the diameter of the sleeve (S) installed in the die (1) is configured to be changed, the diameter is different through the fixing member (10) There is an advantage that can be fixed to the sleeve (S).

In addition, the present invention can be installed by adjusting the vertical height or left and right positions of the support bar 20 is installed on the fixed bar 30, as shown in Figure 6, the sleeve (S) is installed in the formwork (1) You can easily move the position when Therefore, as shown in FIG. 7, since the sleeve S can be easily installed by adjusting the sleeve S to a desired position in the formwork 1, the worker's workability is improved during construction of the retaining wall and the position of the pipe penetrating the wall. According to the installation position can be set precisely, there is an advantage that can greatly increase the workability of the wall.

In addition, in the present invention, since the fixing member 10 is firmly fixed to the formwork 1 through the fixing nail 40, the concrete C is poured into the formwork 1 to form a wall through the formwork 1. When doing so, there is an advantage that the sled portion S fixed to the fixing member is not moved or twisted in place by the load of the concrete C.

On the other hand, as shown in Figure 8, the cushioning rubber pad 60 is interposed between the fixing member 10 and the sleeve (S) to attenuate vibration, shock and noise of the sleeve, to increase the insulation effect It is composed.

Here, the cushion rubber pad 60 uses a polychloroprene (polychloroprene) which is a polymer compound made of a chloroprene polymer. The polychloroprene is a material excellent in durability, ozone resistance, heat resistance and chemical resistance. The cushion rubber pad 60 is a material having excellent dustproof performance to effectively attenuate vibration, shock, and noise, and to prevent excessive vibration, surging, and swinging, and thus may increase an insulation effect.

In particular, the cushion rubber pad 60 has a disadvantage in that the fatigue limit is lost due to the hardening and the deterioration caused by the heat generated during the repeated expansion and contraction of the concrete (C), impact buffering action and the resulting degradation To solve this problem, 2.5% by weight of ammonium persulfate, 5.0% by weight of shungite powder having a particle size of 0.5 μm, 2.5% by weight of boric acid, 3.0% by weight of polyether-block-amide (PEBAX), and latex emulsion It is preferably molded into a composition consisting of 4.0% by weight, 0.2% by weight of silicone oil, 4.5% by weight of polycarboxylate salt, 2.5% by weight of mole curassib, 1.5% by weight of rosin and the remaining polychloroprene.

At this time, the ammonium persulfate (Ammonium Persulfate) is added to suppress heat deformation by adjusting the acidity to enhance oxidation resistance.

In addition, the pure jitter is a natural mineral mainly containing silicate and fullerene, in particular, a powder of a mineral containing a large amount of graphite microcrystals.

Such graphite microcrystals strengthen the heat resistance and reduce the coefficient of thermal expansion, thereby preventing the rubber component of the dustproof pad from deteriorating and suddenly decreasing the fatigue strength caused by repeated bending. In addition, when using pure jits containing 60% or more of fullerene, it prevents contamination and prolongs life because it blocks itself from bacterial growth and activity such as mold caused by the natural antioxidant action of the third allotrope of carbon, fullerene. It is very effective to achieve.

In addition, the boric acid is a salt of oxygen acid having boron as its core atom, and the oxidation resistance is enhanced by binding with graphite microcrystals, thereby maintaining a very small deformation even under load and pressure, thereby suppressing deterioration and preventing high temperature. Less deformation and chemically increase corrosion resistance and abrasion resistance.

In addition, the polyether-block-amide (PEBAX) has a low hardness change, excellent fatigue resistance, and low specific gravity at low temperatures, and excellent molding processability, low hygroscopicity, bending fatigue resistance, weather resistance, flexibility, creep resistance, and adhesion. It is added to enhance the properties.

In addition, the latex emulsion is added to increase the softening point, increase the elongation and increase the viscosity at high temperatures to enhance heat resistance and abrasion resistance.

In addition, since the latex emulsion is formulated in an emulsion state, the silicone oil may be added in small amounts to eliminate the problem of molding failure due to bubble generation.

In addition, the polycarboxylic acid polybasic acid salt is excellent in coloration and viscosity stability as a liquid high-performance dispersant, and is added in the present invention to prevent molding defects such as pinhole generation and wrinkle generation due to non-uniform dispersion during molding.

In addition, the Molecular Sieves are sound-absorbing, sound-absorbing, shock-absorbing by using the characteristics of the strong hygroscopicity and three-dimensional network pore crystal structure having an adsorption capacity close to the saturation adsorption under extremely low water vapor partial pressure Is added to strengthen the.

In addition, the rosin is a pale yellow or brown transparent liquid remaining after distilling the rosin with water vapor to remove terebin oil, controlling the viscosity while enhancing the binding properties between components, increasing the dispersibility of the latex emulsion, binding during molding Is added to increase the force.

Finally, the polychloroprene is the base resin described above.

The molded foam rubber pad 60 was tested for deterioration resistance. The test hit the top of the sample with an impact bar, 20 revolutions per minute, with a 10 kg impact on the sample, which lasted two months.

After 2 months, deterioration on the surface of the sample, that is, whether or not hardening occurred, cracks occurred, or not, was confirmed by using a magnifying glass and a pusher.

As a result, hardening did not occur, elastic recovery force was maintained in a normal state, there was no discoloration, and no crack occurred.

While the invention has been shown and described in connection with specific embodiments as described above, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.
