Description

  The present invention is applied to a portion where the reinforcement of the base concrete itself such as a crack or a crack of the concrete is required, or a poor adhesion portion between the concrete and the finishing material, and the reinforcement of the concrete itself or the finishing material. The present invention relates to a concrete structure reinforcing treatment method and a concrete structure reinforcing agent injecting apparatus that enable adhesion strengthening and waterproofing waterproofing treatment.

Conventionally, concrete structures have problems due to deterioration of various forms described below.
(1) Problems of deterioration and weakening due to the neutralization of concrete.
Carbon dioxide in the atmosphere intrudes into the concrete and neutralizes the alkalinity inherent in the concrete, causing corrosion of the reinforcing bars in the concrete and causing cracks and delamination of the concrete. As a result, the strength is reduced.
(2) Crack generation in concrete.
In concrete structures, cracks on the surface of the concrete are unavoidable due to the properties of the concrete itself, but if left untreated, it becomes a major factor that causes deterioration of the concrete and a decrease in strength.
(3) Peeling / floating / dropping of the finishing material from the concrete structure surface.
Tiles, stones, and mortar coatings are often used as the finishing material for concrete structures, but as the building ages, the finishing material has a binding force with the surface of the structure. Decreases and the finishing material peels off, floats and falls off.
(4) Delays in finding deterioration of concrete structures due to covering with finishing materials Covering concrete surfaces with finishing materials such as tiles, stones, and mortar makes it difficult to detect cracks in the foundation concrete. Rainwater that enters from the joints of the finishing material further penetrates from the cracks and causes water leakage into the building.

Then, about the said problem which a concrete structure has, for example, several treatment methods as listed below are proposed.
(1) As a treatment method for deterioration and weakening due to neutralization (a) Method of covering the surface with a thick steel plate (b) Method of low-pressure injection of a relatively low viscosity epoxy resin with a dedicated injector 2) As a treatment method for cracks (c) A method of low-pressure injection of an epoxy resin having a relatively low viscosity along the cracks with a dedicated injector (d) The concrete surface is shaved so as to form grooves along the cracks, (3) As a treatment method for interfacial peeling / floating / dropping of finishing material (e) Method of removing defective parts such as interfacial peeling / floating and re-paying (f) Interfacial peeling / floating (G) Epoxy resin with relatively high viscosity by punching holes in defective parts such as interfacial peeling and floating Method of injecting under pressure with an injector and finally inserting a stainless pin (h) Method of opening a hole in a defective part such as interface peeling / floating, and injecting low viscosity epoxy resin with a dedicated injector (i) Interface A method of sticking a glass fiber mesh sheet to a defective part such as peeling or floating with a dedicated pin and solidifying the whole with urethane resin. (4) As a method of handling defects when covering concrete surfaces with tiles, stones, mortar, etc. (j ) Method of removing the finishing material around the leaked part, waterproofing the ground concrete and re-applying it (k) Method of injecting epoxy resin around the leaked part by the method (h) (l) From the top of the finished surface How to apply waterproof coating

  However, the method of simply covering the concrete surface of (a) does not improve the concrete itself. In the method of low pressure injection of the low viscosity epoxy resin according to (b), (c) and (h), the epoxy resin is It does not reach the narrow gap of 0.1mm or less. (E) In the method of (j), design with temporary / removal for removal of defective parts, disposal of removed objects, and unreplaced parts after replacement of replacement parts Must be considered. In the method (f) of injecting a relatively high-viscosity epoxy resin under pressure, it is difficult for the epoxy resin to penetrate into the voids, and if the pressure is forced to inject, the finish may float from below. . The methods (b), (c), (d), (f) to (i) all use a resin (organic material) such as an epoxy resin, a sealing material, and a urethane resin, and the strength may decrease due to deterioration over time. There is. Further, the adhesive force of the resin of the object is almost limited to the surface. Furthermore, in the method (k), epoxy resin cannot be filled up to fine cracks through which rainwater passes, and the method (l) has a design problem.

  Therefore, in concrete structures, poor adhesion between concrete fragile parts, concrete cracks (cracked parts), base concrete such as tiled surface, stone-finished surface, and mortar-finished surface, and adhesive mortar for finishing materials Bond concrete structures by applying a concrete structure strengthening agent with high permeability to parts that require bond reinforcement, such as parts, and impregnating, infiltrating and solidifying the reinforcing agent in and around the parts. There is a problem to be solved in terms of strengthening and maintaining the bond strengthened state for a long time.

  The object of the present invention is to provide a portion where the concrete is deteriorated and weak, cracking of the concrete, and a poorly bonded portion between the base concrete such as the tiled finish surface, the stone pasted surface and the mortar finished surface and the adhesive mortar of the finishing material. A concrete structure that can be constructed in a simple manner and at a low cost by strengthening the bond including the surrounding area, and further maintaining the re-adhesion integration and waterproofing waterproof action provided by the treatment for a long period of time. It is providing the reinforcement | strengthening processing method of a thing, and the concrete structure reinforcing agent injection | pouring apparatus used for the said reinforced processing method.

  In order to solve the above-mentioned problems and achieve the above-mentioned object, the method for strengthening a concrete structure according to the present invention applies an inorganic water-soluble ceramic impregnated waterproofing agent in which nano-ultrafine particles are dissolved in the joint-reinforced portion of the concrete structure. And impregnating and infiltrating, and using the nano-ultrafine particles as a binder, the impregnated and infiltrating part of the concrete structure is solidified integrally to strengthen the bond.

  According to this method for strengthening the bond of a concrete structure, an inorganic water-soluble ceramic impregnated waterproofing agent in which nano-ultrafine particles are dissolved is applied to the joint-reinforcing portion of the concrete structure. Nano-ultrafine particles have an ultra-fine nanomolecular structure with a nano-sized particle size and high penetrability, so the inorganic water-soluble ceramic impregnated waterproofing agent whose viscosity is almost equal to water is finer. It impregnates and infiltrates even to the voids, and impregnates and penetrates to the gaps between the cement particles that make up the concrete structure. In addition, the nano-particles themselves have a binder (adhesive) function, and when the inorganic water-soluble ceramic impregnated waterproofing agent impregnated / penetrated in the binding-reinforcing part and its peripheral part is solidified at the impregnation / penetration position It functions as a binder and integrates the gaps between concrete separated by cracks and the like, and poorly bonded parts between the concrete and the finishing material and their periphery by intermolecular bonding, and exhibits a high bonding effect. That is, by applying an inorganic water-soluble ceramic-impregnated waterproofing agent with nano-ultrafine particles as a binder to these required portions in a manner such as injection, application, spraying, etc., the required binding-reinforced portion and its peripheral portion are made of nanoparticles. Integrated and solidified. Since the ceramic-impregnated waterproofing agent used is inorganic, these effects can be maintained unchanged for many years.

  In this method of strengthening a joint of a concrete structure, the required joint strengthening part is a deteriorated weak part of the base concrete constituting the concrete structure or a crack part generated in the base concrete constituting the concrete structure, The inorganic water-soluble ceramic-impregnated waterproofing agent is applied by application or injection to the bond-reinforcing portion. A ceramic-impregnated waterproofing agent can be applied and sprayed on a portion where the base concrete is deteriorated or weakened due to neutralization. Moreover, when a crack part arises in base-material concrete, a ceramic impregnation waterproofing agent can be apply | coated and sprayed to a crack part, or it can apply by injection | pouring. The concrete base to which the ceramic-impregnated waterproofing agent is applied can simultaneously exhibit the functions of re-bonding and waterproofing and waterproofing.

  In this method of strengthening a joint of a concrete structure, the required joint strengthening portion is a poorly bonded portion between the base concrete and the finishing material constituting the concrete structure, and the concrete structure is related to the poorly bonded portion. The ceramic-impregnated waterproofing agent is injected through an injection tool arranged in the formed mounting hole, and when the ceramic-impregnated waterproofing agent is injected, the finishing material can be pressure-bonded to the base concrete by the injection tool. The ceramic impregnated waterproofing agent injected through the injecting tool placed in the mounting hole is impregnated and penetrated from the mounting hole to the poorly bonded portion of the base concrete and the finishing material constituting the concrete structure. When solidified, the nano-particles that function as a binder are solidified by integrating the poorly bonded portion as a binding-reinforcing portion and its peripheral portion.

  In this method for strengthening the bond of a concrete structure, the finishing material is a tile, a stone plate, or a mortar layer applied to the surface of the base concrete by sticking or applying to the surface. When tiled finishing, stone pasting, or mortar finishing is performed on a concrete base, the required joint strengthening portion of the concrete structure includes a poorly bonded portion between the concrete base and the finishing material. There is a phenomenon that a gap occurs in the poorly bonded part, and the finishing material floats from the concrete base. By injecting an inorganic water-soluble ceramic-impregnated waterproofing agent containing nano-ultrafine particles into this gap, nano-ultrafine particles are injected. Impregnates and permeates the poorly bonded part and its surroundings, and acts as a binder when solidifying, thereby integrating the concrete substrate with the finishing material. In other words, if the finishing material is applied to the underlying concrete using an adhesive mortar layer, the finishing material and the mortar layer, and the concrete and the mortar material can be re-bonded to strengthen the tiles and stone-attached joint materials. In addition, waterproofing treatment can be performed.

  In this method for strengthening the bond of a concrete structure, the application of the inorganic water-soluble ceramic impregnated waterproofing agent to the required bond-strengthened part of the concrete structure is a plug-in type injection pin or a fitting hole formed in the mounting hole formed in the concrete structure. This can be done through the inside of an anchor-type crimp injection pin. A mounting hole is formed in relation to the joint strengthening portion of the concrete structure, and the inorganic water-soluble substance is injected through the injection pin that is inserted into the attachment hole or inserted into the attachment hole and is anchored to the attachment hole. By injecting the ceramic-impregnated waterproofing agent, the inorganic water-soluble ceramic-impregnated waterproofing agent can be impregnated and infiltrated into the joint strengthening portion of the concrete structure.

Consists of.

  According to this concrete structure reinforcing agent injection device, the injection tool is mounted by pressing the cylinder into the mounting hole by deformation of the cylinder outside based on the relative movement of the cylinder and the tube in the axial direction. Mounted in the hole. The inorganic water-soluble ceramic-impregnated waterproofing agent is injected from the injection path of the injection tool through the mounting hole into the joint strengthening portion of the concrete structure. This type of concrete structure reinforcing agent injection device uses an injection tool called an anchor-type crimp injection pin, and injects an inorganic water-soluble ceramic-impregnated waterproofing agent into the interface / space between the base concrete and the finishing material. At this time, the inorganic water-soluble ceramic-impregnated waterproofing agent can be efficiently injected in a state where the base concrete and the finishing material are tightened to narrow the gap width and are pressed. Also, by changing the length of the anchor-type crimping injection pin, the tightening thickness, the injection depth of the inorganic water-soluble ceramic-impregnated waterproofing agent, the part to be tightened by changing the thickness, the weight of the finishing material to be borne by the pin, etc. Can be changed.

The injection tool can be mounted in the mounting hole by tightening a nut that is deformed and screwed into the male screw portion to the outer surface of the concrete structure. By driving the cylindrical body into the tubular body, the wedge portion is deformed in such a manner that the wedge portion is expanded radially outward by the wedge action that the cylindrical distal end exerts on the small-diameter distal end portion of the cylindrical body. The wedge portion is strongly pressed against the inner surface of the mounting hole based on this deformation, so that the cylindrical body is fixed in the mounting hole. By rotating the nut screwed into the male thread portion of the cylinder, the nut is brought into contact with the outer surface of the concrete structure, and the injection tool is securely mounted in the mounting hole.

  In the concrete structure reinforcing agent injecting apparatus using an injection tool referred to as an anchor type crimp injection pin, the concrete structure is applied to the base concrete and the base concrete via a mortar layer on the surface. The tube body is a bolt body in which a male thread portion is formed on the outer surface and a head portion that engages with a portion formed in the finishing material of the mounting hole. The cylinder includes a wedge portion divided at the tip, and the cylinder is driven into a cone-shaped pedestal previously loaded in the mounting hole to deform the wedge portion outward. Is fixed in the mounting hole, and the tube body is screwed into the female screw portion formed in the cylindrical body with the male screw portion, so that the head portion of the bolt body is sealingly engaged with the mounting hole via the packing. It is possible. A mode in which the divided wedge portion at the tip of the cylinder extends radially outward by driving the divided tip of the cylinder into a cone such as a cone or a pyramid previously loaded in the mounting hole. The cylindrical body is fixed in the mounting hole by deforming the wedge portion and strongly pressing the wedge portion against the inner surface of the mounting hole based on the deformation. The tube body is composed of a head and a bolt body with an external thread formed on the outer peripheral surface, and the head of the bolt body is mounted via a packing by screwing the male thread into the female thread formed on the cylinder. Since the hole is sealed and engaged, the injected inorganic water-soluble ceramic impregnated waterproofing agent does not leak from the periphery of the head of the tube.

Further, the packing is disposed between a step portion formed at a boundary where the mounting hole is connected to a relatively small diameter portion formed in the adhesive mortar layer from a relatively large diameter portion formed in the finishing material. The bolt body can be hermetically engaged by being sandwiched between the head portion and the step portion. Further, the packing is disposed in the mounting hole formed in the finishing material, and a column portion and a tapered constricted portion formed in the head portion of the bolt body and a cylindrical inner surface of the mounting hole, respectively. It has a cylindrical portion and a tapered enlarged portion sandwiched between them, and can be sealed and engaged by a wedge action based on the tapered shape.

A rubber packing having a tapered constricted portion at a position to be a mounting tip, and the tubular body has a tapered enlarged portion engageable with the tapered constricted portion of the rubber packing at the distal end. And sealing means for sealing between the inner surface of the loading hole and the outer peripheral surface of the tube body, and locking means for locking the tube body at a predetermined position between the tube body and the tube body. The tube is relatively moved in the loading hole and deformed to expand the rubber packing outward by a wedge action between the tapered constricted portion and the tapered enlarged portion. Insert your body into the mounting hole By the locking means in a state capable of engaging the said tube body in said loading hole. In this case, the injection tool can be mounted in the mounting hole in a one-touch manner, and the mounting hole and the injection tool can be sealed and engaged with the rubber packing.

  The concrete structure reinforcing agent injecting apparatus according to the present invention further includes an injecting device that is mounted in a sealed state in a mounting hole formed in the concrete structure, and the injecting device is an injection port attachment that is mounted in the mounting hole. And a cylinder connected upward to the injection port attachment, and the inorganic water-soluble ceramic-impregnated waterproofing agent stored in the cylinder is injected into the mounting hole with a pressure based on its own weight. This concrete structure reinforcing agent injection device is a plug-in type injection pin type device, and can be easily mounted in the mounting hole by insertion. At the time of mounting, a sealed state can be obtained by interposing a packing between the inlet attachment and the mounting hole. Since the inorganic water-soluble ceramic impregnated waterproofing agent is injected at a pressure based on its own weight, a special pressurizing device for injection is unnecessary, and it is possible to inject the inorganic water-soluble ceramic impregnated waterproofing agent at a simple and low cost. it can.

  Furthermore, the concrete structure reinforcing agent injecting apparatus according to the present invention includes an injecting device that is mounted in a sealed state in a mounting hole formed in the concrete structure, and the injecting device is an injection port that is mounted in the mounting hole. An attachment, a cylinder with a piston connected to the inlet attachment, and a biasing means for biasing the piston in a direction to push the piston into the cylinder, and the inorganic water-soluble ceramic-impregnated waterproofing agent stored in the cylinder is Injecting into the mounting hole with a pressure based on the biasing force of the biasing means. This concrete structure reinforcing agent injection device is also a plug-in type injection pin type device, which can be easily mounted in the mounting hole by insertion, and a packing is interposed between the inlet attachment and the mounting hole when mounting. By doing so, a sealed state is obtained. Since the inorganic water-soluble ceramic-impregnated waterproofing agent is injected at a pressure based on the urging force using an urging means such as rubber, a pressurizing device for the injection can be simply configured, and it is simple and low-cost. The inorganic water-soluble ceramic impregnated waterproofing agent can be efficiently injected without backflow at a cost.

An injection gun supplied to the injection tool and a flow meter capable of measuring the flow rate of the inorganic water-soluble ceramic-impregnated waterproofing agent supplied from the injection gun can be provided. If a supply system including a pressurized tank, an injection gun, and a flow meter is prepared, an inorganic water solution can be applied to the injection device installed in a number of installation holes by attaching the injection device to the supply destination from the injection gun. The injection work of the water-resistant ceramic impregnated waterproofing agent can be performed efficiently.

  According to the method for strengthening the bonding of a concrete structure according to the present invention, a synthetic resin adhesive having a different and high viscosity is injected into a gap formed between a conventional concrete and a mortar, and the two are bonded together with an adhesive force only on each surface.・ Unlike water-stopping methods, inorganic water-soluble ceramic-impregnated waterproofing agent is efficiently and reliably applied to concrete foundations, finishing materials, etc. where bonding reinforcement is required in appropriate modes such as coating, spraying, and pouring. In addition, an inorganic water-soluble ceramic-impregnated waterproofing agent can be impregnated and infiltrated into the joint-reinforcing part.

  In addition, ceramic impregnated waterproofing agent is applied to and around deteriorated and weak parts of concrete structures, concrete cracks and their surroundings, and poorly bonded parts such as tiled finish, right paste finish, and mortar finish.

By inter-bonding, the fragile parts, cracks, poorly bonded parts and their surroundings are strengthened as one body, and a high bonding effect is exhibited. The gaps between concrete such as cracks and the gaps between concrete and finishing material are filled with gelled fine particles, which are finally vitrified and integrated, leaving no room for rainwater to enter. Demonstrate waterproofing effect. Since the inorganic water-soluble ceramic-impregnated waterproofing agent used is inorganic, these effects can be maintained for many years.

  In the concrete structure reinforcing agent injecting apparatus of the present invention, when using an anchor-type crimping injection pin, when repairing a bonding failure portion such as a tiled finished surface, a stoned finished surface, a mortar finished surface, and the periphery thereof. , Against the lifting of finishing materials such as tiles, stone plates and mortar from the base concrete, the anchor effect of fastening the finishing material to the base concrete with bolts is obtained, and the gap width generated by the floating is narrowed and crimped In this state, the ceramic-impregnated waterproofing agent can be injected into the interface / gap between the base concrete and the finishing material and the periphery thereof without backflow. Thereby, it is stronger than inserting a stainless steel pin into a hole into which a follower epoxy resin is injected, and it is possible to realize reintegration and integration with the base concrete while having an anchor effect by the stainless steel pin. Also, by changing the length of the anchor-type crimping injection pin, the tightening thickness and the injection depth of the inorganic water-soluble ceramic impregnated waterproofing agent, and by changing the thickness, the part to be tightened, the weight of the finishing material to be borne by the pin, etc. It can be easily changed.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a concrete structure bonding / strengthening method and a concrete structure reinforcing agent injecting apparatus used therefor will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of a method for strengthening a bond of a concrete structure 1 according to the present invention. FIG. 2 is an enlarged longitudinal sectional view showing the concrete structure reinforcing agent injection device (hereinafter abbreviated as “injection device”) 10 shown in FIG. In the concrete structure 1, a tile 5 as a finishing material is attached to a surface 3 of a base concrete 2 via an adhesive mortar layer 4. FIG. 1 shows an inorganic water-soluble ceramic impregnated waterproofing agent (hereinafter abbreviated as “ceramic impregnated waterproofing agent”) that uses nano-ultrafine particles, which are reinforcing agents, as a binder for a concrete structure 1 through an injection device 10. ) Indicates the state of injection. In FIG. 1, an example of construction on a joint 6 made of the same mortar material as the adhesive mortar layer 4 is shown on the left side, and an example of construction from the surface 7 of the tile 5 is shown on the right side. In any case, the adhesive mortar layer 4 is lifted from the surface 3 of the base concrete 2 to form a gap 8, and a poorly bonded portion due to the gap 8 is a necessary joint strengthening portion. By rebonding the gap 8, integration and strengthening of bonding between the base concrete 2 and the adhesive mortar layer 4 are required.

  In the construction example shown in FIG. 1, the concrete structure 1 is previously penetrated from the surface 6 of the joint 6 or the tile 5 through the adhesive mortar layer 4 with a drilling tool such as a drill to the base concrete 2 to a predetermined depth. A mounting hole 9 reaching up to is formed. The injection device 10 is omitted from the illustration, an injection tool 11 mounted in the mounting hole 9, an injection tube 28 connected via a tube body 15 with a male screw portion 18 protruding to the front side of the injection tool 11, and illustration. However, it is equipped with a pressure feeding means such as a pump for feeding the reinforcing agent and a tank for storing the reinforcing agent. In this example, the injection tool 11 is configured as an anchor type pressure injection injection pin. Although details will be described later, the injection tool 11 has an anchor pin function for preventing the tile 5 and the mortar layer 4 from floating from the surface of the base concrete 2. Using this pin, a ceramic-impregnated waterproofing agent is injected through the inside of the pin into the interface / gap between the base concrete and the finishing material and in the vicinity thereof. First, the injection tool 11 is mounted in each mounting hole 9 formed in the concrete structure 1, and the injection tube 28 is connected to the tube body 15 in this state.

  As shown in FIG. 2, the injection tool 11 includes a cylindrical body 12 in which a cylindrical inner surface 14 is formed by a through-hole 13, and an injection path 16 that passes through the through-hole 13 of the cylindrical body 12 and extends axially therein. Is formed. The cylindrical body 12 is formed with a male screw portion 18 into which a fixing nut 22 described later is screwed on the proximal end side, that is, the proximal side at the time of construction, and is divided by a slit 20 on the distal end portion 19 side. A plurality of wedge portions 21 are formed. The wedge portion 21 is formed in a tapered shape with the outer surface spreading toward the far end side (FIG. 1). The initial maximum dimension of the tapered portion is slightly shorter than the diameter of the mounting hole 9 and can be inserted into the mounting hole 9. The nut 22 includes a flange 23 for contact with the tile 5. A plurality of communication holes 26 communicating with the internal injection path 16 and communicating with a gap 25 formed between the cylindrical body 12 and the shaft body 15 are provided at predetermined positions on the distal end portion 17 side of the tube body 15. Is formed. The gap 25 communicates with the outside of the injection tool 11 through the slit 20 or the like. The distal end portion 17 of the tubular body 15 is formed straight except that the distal end portion is sharp, but the width of the adjacent wedge portions 21 and 21 is initially narrower than the distal end portion 17 of the tubular body 15. ing. In addition, the clearance gap between the cylinder 12 and the pipe body 15 can provide the suitable seal | sticker 24 which prevents the leakage of a ceramic impregnation waterproofing agent, although a relative movement is accept | permitted by the base end part side.

  After the injection tool 11 in a state where the tube body 15 is shallowly loaded in the tube body 12 is loaded into the mounting hole 9, the tube body 15 is driven deeply into the tube body 12. At this time, the distal end portion 17 of the tube body 15 enters between the wedge portions 21 and 21 of the cylindrical body 12 with the sharp tip portion first, so that the wedge portions 21 and 21 are In response to deformation spreading outward, the mounting hole 9 is strongly pressed against the inner surface of the base concrete 2. The cylinder 15 is fixed in the mounting hole 9 by the frictional force resulting from the pressure contact force. Thereafter, the nut 22 is rotated by an appropriate tool and screwed into the male thread portion 18 of the cylinder 12. The nut 22 is initially advanced by screw engagement with the male screw portion 18, but after the flange 23 approaches and comes into contact with the tile 5, the tile 5 is pressed by the flange 23, so that the adhesive mortar layer 4 and the tile 5 are brought together. It is pressed toward the surface 3 of the base concrete 2 in the direction of narrowing the gap width of the gap 8.

  When the fixing of the injection tool 11 is completed, the injection pipe 28 is connected to the pipe body 15 (FIG. 1), and the ceramic-impregnated waterproofing agent supplied through the injection pipe 28 is sent into the injection tool 11 through the pipe body 15 and communicated. It is injected into the mounting hole 9 through the hole 26, the gap 25 and the slit 20. The ceramic-impregnated waterproofing agent injected into the mounting hole 9 enters the gap 8 generated between the surface 3 of the base concrete 2 and the adhesive mortar layer 4 to fill the gap 8, and the nano-ultrafine particles It easily penetrates and impregnates between the particles constituting the surrounding base concrete 2 and the adhesive mortar layer 4. When the injection pressure of the ceramic-impregnated waterproofing agent acts on the gap 8, a force to lift the adhesive mortar layer 4 and the tile 5 from the base concrete 2 is generated, but the injection tool 11 acts as an anchor effect on the tile 5 and the adhesive mortar layer. Since 4 is pressed, the lift does not increase. The name of the anchor-type crimping injection pin is based on the fact that such an anchor effect can be obtained. After injection of the ceramic impregnated waterproofing agent, the injection tube 28 is removed from the injection tool 11 and an appropriate stopper is plugged. When the ceramic-impregnated waterproofing agent is solidified, the adhesive mortar layer 4 is re-adhered and integrated with the base concrete 2, and the region where the ceramic-impregnated waterproofing agent penetrates is reinforced. The injection tool 11 does not need to be removed after construction, and remains in an integrated state with the concrete structure 1. As for the anchor-type crimping injection pin, the same applies to the examples described later, but by changing the length of the pin, the tightening thickness, the injection depth of the ceramic-impregnated waterproofing agent, and the thickness can be changed. The part to be tightened and the weight of the finishing material to be borne by the pin can be changed.

  FIG. 3 is a diagram showing a construction example using an injection tool that takes the form of an anchor-type crimp injection pin provided embedded from the surface 7 of the tile 5. (A) is a top view, (b) is a side view which shows the mode of construction to the concrete structure 1 shown with the cross section. As in the example shown in FIG. 1, before installation, a mounting hole 49 for inserting a pin is formed in advance over a predetermined depth of the base concrete 2 through the adhesive mortar layer 4 from the surface 7 side of the tile 5. Yes. The injection tool 31 used in the injection device 30 includes a cylindrical body 32 in which a female screw portion 33 opened on the opening side of the mounting hole 49 is formed, and a male screw portion 35 that can be screwed into the female screw portion 33 of the cylindrical body 32. And a bolt body 34 formed with. The cylindrical body 32 is divided into a wedge portion 37 by dividing the distal end side in the circumferential direction by a slit 36. The mounting hole 49 is formed to have a diameter slightly larger than the outer diameter of the wedge portion 37, so that the cylindrical body 32 can be loaded. The base end side of the bolt body 34 is an enlarged head 38 that can be engaged with the rotary tool, and an injection path 39 that penetrates from the end surface of the enlarged head 38 to the tip of the male screw portion 35 is formed. . A port 41 that can be connected to an injection pipe for supplying a ceramic-impregnated waterproofing agent is formed on the upper surface of the enlarged head 38.

At the innermost part of the mounting hole 49, the cylindrical body 32 is stably seated and the wedge portion 37 is deformed in such a manner as to expand radially outward, and the waste space is reduced to save the injection amount of the ceramic-impregnated waterproofing agent. A cone-shaped pedestal 42 is disposed. The pedestal 42 is first loaded in the bottom of the mounting hole 49, and then the cylindrical body 32 is loaded in the mounting hole 49 with the wedge portion 37 facing first. The cylindrical body 32 is driven into the pedestal 42 with an appropriate tool, and the wedge portion 37 is deformed so as to open outward. The deformed wedge portion 37 is strongly pressed against the inner surface of the base concrete 2 in the mounting hole 49, and the cylindrical body 32 is fixed to the base concrete 2 by this press contact. Further, when the packing 40 is arranged at the corner 5a of the tile 5, the bolt body 34 is loaded into the mounting hole 49 in this state, and the male screw part 35 is screwed into the female screw part 33 of the cylindrical body 32, the bolt body. 34 enlarged heads 38 come into contact with the corners 5 a of the tiles 5 through the packing 40. The adhesive mortar layer 4 and the tile 5 are pressed from the surface side by the enlarged head 38 of the bolt body 34. When the attachment of the injection tool 31 is completed, an injection pipe (not shown) similar to the injection pipe 28 shown in FIG. The injection of the ceramic-impregnated waterproofing agent and the subsequent processing are the same as those in the example shown in FIG. Even when the ceramic-impregnated waterproofing agent is injected with pressure, it is possible to prevent the tile 5 from being lifted from the base concrete 2 as well as the adhesive mortar layer 4 by the pressing by the enlarged head 38.

  Instead of the structure shown in the drawing, the tip of the male threaded portion 35 of the bolt body 34 is screwed into the pedestal 42, and the pedestal 42 is moved up by the rotation of the shaft body 34 while the lifting of the cylindrical body 32 is suppressed. By doing so, the wedge portion 37 may be expanded outward. The packing 40 avoids direct contact between the enlarged head 38 and the tile 5 to protect the tile 5 and seal the mounting hole 49 to the outside. Since the enlarged head 38 is also in contact with the side surface of the tile 5 via the packing 40, the lateral displacement of the tile 5 can also be restricted.

  FIG. 4 shows an injection device in the form of an anchor type crimp injection pin which is provided embedded from the surface 7 of the tile 5 as in FIG. In FIG. 4, (a) is a plan view, and (b) is a side view showing a state of construction on the concrete structure 1 shown in cross section. The injection device 50 shown in FIG. 4 is the same in the injection tool 51 except that the shape of the head 58 of the bolt body 54 and the position applied to the concrete structure 1 are different. Thus, the description thereof is omitted. In the tightened state of the bolt body 54, the head 58 of the bolt body 54 is completely accommodated in the hole 5b of the tile 5 in the mounting hole 49. 51 does not jump out, and the appearance after construction can be improved. Further, the corner 4a of the adhesive mortar layer 4 is stepped because it has a slightly smaller diameter than the hole 5b of the tile 5. In the tightened state of the bolt body 54, the head 58 is in contact with the corner portion 4 a of the adhesive mortar layer 4 via the packing 52, and the gap width of the gap 8 is increased toward the base concrete 2. The mounting hole 49 is sealed by the packing 52 while being pressed so as to be narrowed. Therefore, when the ceramic-impregnated waterproofing agent is injected with pressure, the adhesive mortar layer 4 is prevented from floating and the ceramic-impregnated waterproofing agent is prevented from leaking out of the mounting hole 49. The filling / fixing of the injection tool 51, the connection of the injection tube 28, the filling of the ceramic-impregnated waterproofing agent into the gap 8 and the strengthening of the connection are the same as in the example shown in FIG. .

  FIG. 5 shows an injection device in the form of yet another type of anchored crimp injection pin. As in the example shown in FIG. 4, the injection tool 61 used in the injection device 60 shown in FIG. 5 is such that the head 68 of the bolt body 64 does not protrude above the level of the upper surface of the tile 5. It is a device in a form that can improve the appearance of the device. Since there is no difference except that the shape of the head 68 of the bolt body 64 and the position applied to the concrete structure 1 are different, the same structure as in FIG. In the example shown in FIG. 5, the head 68 of the bolt body 64 is formed with a circular section 68 a having the same cross section on the hand side and a tapered constricted section 68 b like a truncated cone on the male screw section 35 side. Thus, only the inner surface 5 b of the mounting hole 49 formed in the tile 5 is engaged. In the packing 62, the upper half structure 62 a is a thin cylindrical portion corresponding to the circular section 68 a of the head 68, but the lower half structure 62 b continuously connected to the upper half is a tapered constriction of the head 68. Corresponding to the only portion 68b, it is formed in a taper-shaped enlarged portion having a substantially triangular cross-section formed thicker toward the bottom. When the bolt body 64 is screwed into the cylindrical body 32, the bolt body 64 tries to descend in the mounting hole 49 formed in the tile 5 by the screw action, but the head 61 is moved by the wedge action of the lower half structure 62b of the packing 62. It stops due to being strongly pressed against the inner surface 5b of the tile. Since the wedge portion 37 of the cylindrical body 32 protrudes outward and deforms and engages with the inner surface of the mounting hole 49, the injection tool 61 is not detached from the mounting hole 49, and the tile 5 and the adhesive are bonded by the elastic force of the packing 62. The mortar layer 4 is pressed against the surface 3 of the base concrete 2. The packing 62 seals the mounting hole 49 from the outside.

  FIG. 6 is a diagram showing an example of an injection device in the form of a one-touch type injection attachment. FIG. 6A is a diagram showing a state immediately before mounting although it is arranged in the mounting hole, and FIG. 6B is a diagram showing a state after mounting. In the injection device 70 shown in FIG. 6, an injection tool 71 includes a cylindrical body 72 in which a loading hole 73 is formed in the form of a through-hole, and a insertion hole 73 inserted into the cylindrical body 72. And a pipe body 74 in which an injection path 75 for injecting a bond reinforcing agent is formed. The cylindrical body 72 is provided with a rubber packing 76 having a tapered inner surface at the distal end mounted in the mounting hole 89 and is radially inward by a spring 80 on a head 78 positioned outside the concrete structure 1. A biased bearing (click ball) 81 is provided. In addition, the tube body 74 includes a wedge portion 77 that can be wedge-engaged from the inner side with respect to the rubber packing 76 of the cylindrical body 72 at the tip, an O-ring 82 that seal-engages with the inner surface of the loading hole 73, and A concave portion 83 into which the bearing 81 can be fitted is formed on the peripheral surface.

  As shown in FIG. 6B, when the tube body 74 is pulled up with respect to the cylinder body 72 until the bearing 81 is fitted in the recess 83, the wedge portion 77 provided at the tip of the tube body 77 comes into contact with the rubber packing 76. Further, it is deformed so as to spread outward. Since the rubber packing 76 strongly contacts the inner surface of the injection hole 89, the injection tool 71 is prevented from being detached from the mounting hole 89, and at the same time, the rubber seal 76 is used to bond the reinforcing agent as a ceramic-impregnated waterproofing agent to the mounting hole 89. A sealing action that prevents leakage of the liquid to the outside is obtained. In a state where the bearing 81 is fitted in the recess 83, the wedge portion 77 is sufficiently in contact with the rubber packing 76, and the mounting force of the tubular body 72 to the mounting hole 89 and the engaging force of the tubular body 77 to the tubular body 72 are sufficient. And the injection tool 71 is securely mounted in the mounting hole 89. In order to remove the injection tool 71 from the mounting hole 89, the reverse operation starting from pushing the tube 77 into the cylinder 72 may be performed. The connection of the injection tube 28, the injection of the bond reinforcing agent, etc. may be performed according to the previous example.

  FIG. 7 is a schematic diagram showing an example of a supply system in the ceramic impregnated waterproofing agent injection apparatus employing the one-touch type injection attachment as shown in FIG. A constant pressure is applied to the pressurized tank 90 by pressure from a cylinder or a compressor (not shown). A supply pipe 91 that opens near the bottom of the pressurized tank 90 is connected to a supply gun 92. The ceramic impregnated waterproofing agent can be injected through the injection tube 28 when operating the supply gun 92 by pulling the trigger 94. The supply gun 92 is provided with a flow meter 93, and the supply amount of the ceramic-impregnated waterproofing agent can be known from the display of the flow meter 93.

  FIG. 8 shows an example of an injector having the form of a plug-in type injection pin used in the ceramic impregnated waterproofing agent injection device according to the present invention. The injection device 100 shown in FIG. 8 includes an injection port attachment 101 attached to a joint-reinforcement portion of the concrete structure 1 and an injection device 102 similar to the shape of a syringe that can be connected to the injection port attachment 101. Yes. The inlet attachment 101 includes an introduction tube portion 105 connected to the injector 102, an injection tube portion 106 inserted through a packing 104 into a mounting hole 103 formed in a required joint strengthening portion, and an introduction tube portion 105 and an injection A switching valve 107 provided at a portion intersecting with the pipe portion 106 is provided. The name of the plug-in type injection pin is based on the fact that the injection port attachment 101 is attached to the attachment hole 103 by inserting the injection tube portion 106 into the attachment hole 103. By changing the rotation position of the switching valve 107, the introduction pipe part 105 and the injection pipe part 106 can be communicated or blocked. Further, the switching valve 107 can be turned to disconnect the introduction pipe part 105 from the injection pipe part 106 and connect it to the discharge pipe part 108 side. The injector 102 has a structure of a graduated cylinder, and spans between the cylinder 109 with the outer scale 110, the piston 111 fitted in the cylinder 109, the cylinder 109 and the piston 111, and the piston 111. And a rubber band 112 that urges the cylinder 109 into the cylinder 109. The capacity (length and diameter) of the injector 102 can be changed depending on the application.

  As shown in FIG. 8, the cylinder 109 is filled with a ceramic-impregnated waterproofing agent. When the switching valve 107 is rotated to connect the introduction pipe portion 105 and the injection pipe portion 106, the rubber band 112 tries to push the piston 111 into the cylinder 109 by the biasing force. The ceramic-impregnated waterproofing agent is injected from the introduction tube portion 105 through the injection tube portion 106 into the injection hole 103 formed in the strengthening request portion. The injection pressure of the ceramic-impregnated waterproofing agent based on the rubber band 112 is set to a low pressure. By switching the switching valve 107 when a predetermined amount of the ceramic-impregnated waterproofing agent is injected, backflow of the ceramic-impregnated waterproofing agent sent to the injection pipe portion 106 is prevented. The injector 102 can be removed from the inlet attachment 101 and moved to the next construction part. The inlet attachment 101 can be left in that state until the ceramic-impregnated waterproofing agent is solidified.

  FIG. 9 shows an example of a gravity type injector used in the ceramic impregnated waterproofing agent injection apparatus according to the present invention. The injection device 120 shown in FIG. 9 is different from the injection device 100 of the type shown in FIG. 8 only in that the piston 111 and the rubber band 112 are not provided, and other structures are common. The same structure is denoted by the same reference numeral, and the description thereof is omitted. Since the ceramic-impregnated waterproofing agent in the cylinder 109 gives the water pressure sent to the injection pipe portion 106 by its own gravity, the piston 111 and the rubber band 112 are not necessary, and the injection device can be configured most simply. The injection pressure tends to increase as the amount of the ceramic-impregnated waterproofing agent remaining in the cylinder 109 increases, but the injection pressure decreases as the remaining amount decreases.
