An adhesive filler apparatus is disclosed comprising an injector and a support portion, the injector comprising a pressure buffer tube made of an elastic material and check valves adjacent both ends of the pressure buffer tube, the support portion comprising a base member and a projection. The adhesive filler apparatus disclosed is used as follows: A hose connected to a pump is coupled to one end of the pressure buffer tube so that the nozzle of the hose presses the check valve to clear its closure, allowing an adhesive to be fed in the pressure buffer tube. The hose is disconnected from the fed and swollen tube, causing the check valve to close the end of the tube. The fed injector is coupled to the support portion fixed on the crack developed in a concrete structure, etc., whereupon the projection on the support portion presses the check valve to open the end of the tube, thereby allowing the adhesive in the tube to be filled in the crack by gradual and continuous contraction of the elastic tube. Where the quantity of adhesive reserved in the tube is not enough, adhesive can be supplemented in the tube through the other end of the tube left idle so that the injector need not be detached from the crack for supplementation of adhesive in the tube.

1. An apparatus for filling an adhesive in the portions of a structure to be repaired by filling an adhesive therein, comprising an injector and a support portion, said injector including a pressure buffer tube with coupler members at both ends thereof and check valves between both ends of said pressure buffer tube and said coupler members, said check valves being so actuated by the pressure from the pressure buffer tube as to close the passage of adhesive through the pressure buffer tube and the coupler member while said check valves being so actuated by the pressure from the coupler member side as to open said passage, said support portion including a coupler projection and a base member, said coupler projection having a passage therethrough and serving to press one of said check valves upon connecting said injector to said support portion to restore said passage of adhesive. 2. An apparatus according to claim 1, which is provided with a sheath around the pressure buffer tube having a larger diameter than the pressure buffer tube. 3. A method of filling an adhesive in the portion of a structure to be repaired by filling an adhesive therein, using the apparatus as described in claim 1, comprising feeding an adhesive in the pressure buffer tube through one of the coupler members so as to swell the pressure buffer tube, connecting the coupler member of the fed injector to the coupler projection of the support portion fixed on the portion of a structure to be repaired, whereupon one of the check valves is pressed by the coupler projection of the support portion to restore the passage through the pressure buffer tube, the coupler member and the portion of a structure to be repaired, thereby allowing the adhesive to be filled in the portion of a structure by the gradual and continuous contraction of the pressure buffer tube. 4. A method of filling an adhesive in the portion of a structure to be repaired by filling an adhesive therein, using the apparatus as described in claim 2, comprising feeding an adhesive in the pressure buffer tube through one of the coupler members so as to swell the pressure buffer tube until it touches the sheath around it, connecting the coupler member of the fed injector to the coupler projection of the support portion fixed on the portion of a structure to be repaired, whereupon one of the check valves is pressed by the coupler projection of the support portion to restore the passage through the pressure buffer tube, the coupler member and the portion of a structure to be repaired, thereby allowing the adhesive to be filled in the portion of a structure by the gradual and continuous contraction of the pressure buffer tube. 5. A method according to claim 3, further comprising supplementing adhesive in the pressure buffer tube through the coupler member left idle by pressing the check valve so as to swell the pressure buffer tube, thereby filling the adhesive in the cracks or the like of a structure by the gradual and continuous contraction of the pressure buffer tube. 6. A method according to claim 4, further comprising supplementing adhesive in the pressure buffer tube through the coupler member left idle by pressing the check valve so as to swell the pressure buffer tube, thereby filling the adhesive in the cracks or the like of a structure by the gradual and continuous contraction of the pressure buffer tube.
