Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete surface protection device having a mortar layer formed between panels attached to a concrete surface.

[0002]

2. Description of the Related Art Conventionally, as a concrete surface protecting apparatus of this type, a concrete surface coated with mortar or a synthetic resin coating layer is formed.

It is known in the recent technology that a material with a mark such as Nippon Steel High Guard or High Work is used as a coating layer.

[0004]

The problems described in the prior art have the problems that they are easily peeled off, have rainwater permeability, and have a high degree of pollution.

Therefore, according to the present invention, a panel having the same surface area is cut into a cross shape on the concrete surface, anchors are inserted into the insertion holes at predetermined intervals and nuts are attached on the washers, and the panel and the concrete surface are separated. Around the stainless steel anchor, an outer ring, a rubber foaming agent, that is, packings, is inserted around it, and an inorganic material (special mortar) is injected between the concrete body and the panel to integrate it with the concrete to protect and protect the concrete. This is the point of trying to form a costume.

[0006]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a plurality of panels corresponding to the surface shape of the concrete main body at predetermined intervals on the surface of the concrete. To arrange. An insertion hole is formed near the peripheral edge of this panel, and a stainless steel anchor is inserted into this insertion hole to drive the concrete body.
In the space formed between the panel and the concrete body, a spring is provided centering on the stainless steel anchor, and the stainless steel anchor and the spring are surrounded by a rubber foaming agent. It is characterized in that joints are formed between the panels with a foaming agent and mortar or the like is filled in a space partly formed by the foaming agent.

According to a second aspect of the present invention, the upper and lower panels according to the first aspect are provided with an air vent pipe, and the openings of the air vent pipes are formed in the lower surfaces of the upper and lower panels. It is characterized in that an opening is communicated with the section, and each panel is provided with an injection port.

According to the third aspect of the present invention, a reinforcing bar is provided in the space formed between the concrete body and the panel, and the reinforcing bar is filled with mortar or the like. Characterize.

The invention according to claim 4 of the present invention is characterized in that the panel is made of metal, synthetic resin, plywood or the like.

[0010]

[Operation] When mortar is injected into the space between the concrete body and the panel through the injection port, air is mixed with the mortar in the lower panel first, but the mortar is filled in the lower panel and the mixed air is not mixed. Flow into the upper panel through the air bleeding hose and remove it. On the contrary, when the space of the upper panel is filled with mortar, the mixed air moves into the panel on the opposite side and is discharged so that the mixed air flows into the lower panel through the air release hose and is discharged to the outside. Is filled with mortar.

EXAMPLES The examples shown in FIGS. 1 to 6 will be described. A plurality of panels 2 and 3 are arranged on the surface of the concrete body 1 at predetermined intervals so as to correspond to the surface shape of the concrete body 1. The panels 2, 3 are preferably made of a material such as iron, stainless steel, plastic, plywood, etc., and are formed in a rectangular flat plate shape in this embodiment. An insertion hole 4 is formed on the inner sides of the outer circumferences of the panels 2 and 3. A stainless steel anchor 6 is inserted through the insertion holes 4 of the panels 2 and 3, and the stainless steel anchor 6 is placed on the surface of the concrete body 1 to maintain a constant height between the concrete body 1 and the panels 2 and 3. In order to form the space portion 5 inside, a washer and a nut are inserted into the outer end of the stainless steel anchor 6 and fixed by fastening. In the space 5 provided between the concrete body 1 and the panels 2 and 3, a spring 9 is provided opposite to the stainless anchor 6 as shown in FIGS. 2 and 5, and the periphery thereof is surrounded by a rubber foaming agent 10. are doing. Rubber foaming agent 10
Has a function of correcting the height of the panels 2 and 3 together with the function of packing. Reference numeral 7 is a vertical joint of the panels 2 and 3, and 8 is a horizontal joint of the panels 2 and 3. A foaming agent 11 is interposed between these joints 7 and 8 and the concrete body 1 to form a space 5 partitionally between the panels 2 and 3 and the concrete body 1, and to form the space 5 Are closed with the foaming agent 11. The air vent pipe 12 is formed so as to extend across the lateral joint 8 and open at both mouth ends into the space portions 5 and 5 formed below the upper panel 2 and the lower panel 3 so that the upper and lower space portions 8 communicate with each other. ing. The injection port 13 is bored in the panels 2 and 3, and an inorganic material such as special mortar is injected into the space 5 formed between the concrete body 1 and the panels 2 and 3 by an arbitrary mechanism. Then, it is integrated with the concrete body 1 to protect the concrete and improve its appearance. A resin material may be used depending on the working conditions. In some cases, a reflector, such as aluminum, slate, or stainless steel, is left as a makeup.

Next, another embodiment of the present invention will be described with reference to FIG. Portions having the same operations as those of the above-described embodiments shown in FIGS. 1 to 6 are designated by the same reference numerals. The present embodiment shows a concrete surface protection device in the case where the space 5 existing between the concrete body 1 and the panels 2 and 3 is wide. Thus, when the space 5 between the concrete body 1 and the panels 2 and 3 is wide, the joints 7 and 8 between the panels 2 and 3 are
The foaming agent 11 is provided in the portion corresponding to the above to close the space 5. Reinforcing bars 14 are provided in the space 5 and stainless steel anchors 6 respectively.
It is placed on the concrete body 1 by.

[0013]

According to the present invention, since the panel is attached to the concrete body by interposing the foaming agent and the spring between the panel and the concrete body, it is possible to adjust the distance between the surface of the concrete body and the panel. Effective

Further, a foaming agent is provided between the panels, and the upper and lower panels are divided to straddle the air vent pipe, and then each inlet is provided in the upper and lower panels to inject mortar into the space. Since the above structure is continuously provided, the mortar is smoothly and uniformly filled while discharging the air in the space, so that the concrete surface and panel are integrated and the concrete thickness is protected and beautiful. There is a dressing effect. As the reflector, for example, slate, aluminum, stainless steel plate or the like may be left for makeup or light reflection to enhance the effect. Further, if necessary, a double concrete layer is formed in an equal space portion using a resin-based material to prevent intrusion of water, chemicals, etc. to prevent deterioration of concrete and cracks. When the amount of injection is large, the reinforcement is stopped by the set anchor to fill the mortar and the concrete surface can be fully protected.
