Abstract An adhesive filler apparatus is disclosed comprising an injector and a support portion, the injector comprising a pressure buffer tube made of elastic material and a check valve adjacent one end of the pressure buffer tube, the support portion comprising a base member and a projection. The adhesive filler apparatus disclosed is used as follows: An adhesive is fed through a hose connected to a pump, etc. in the pressure buffer tube, causing the tube to swell. The hose is disconnected from the injector, causing the check valve to close the end of the tube. The fed injector is coupled to the support portion fixed on the crack of a concrete structure, etc., whereupon the projection on the support portion presses the check valve to open the end of the fed tube, thereby allowing the adhesive in the tube to be filled in the crack by gradual and continuous contraction of the elastic tube.
An adhesive filler apparatus comprising a support portion provided at one end with a base member for locating the support portion on the portion which is to be repaired by filling an adhesive therein and at the other end with a tubular coupler projection, an injector including a pressure buffer tube, a tubular coupler member at one end of said pressure buffer tube for connecting the injector to said support portion, and a valve device between said pressure buffer tube and coupler member, the other end of said pressure buffer tube being made capable of being closed, the closure provided by said valve device being cleared upon connecting said coupler member to said coupler projection.
