The present invention relates to a joint core for joining a column and a beam that may secure excellent rigidity by a simple process and not require welding. To this end, provided is a joint core for joining a column and a beam, comprising: a closed-section intermediate column; a diaphragm; and an internal reinforcement, wherein the diaphragm is formed with a slit to insert the internal reinforcement thereinside, and the internal reinforcement inserted in the diaphragm is engaged with the intermediate column. According to the present invention, high rigidity is secured when a closed-section column and a beam are joined together as compared to that of the conventional art. In addition, assembly without welding is possible when the closed-section column and the beam are joined together, such that the process may be shortened, the joining may be easily performed, and quality becomes uniform.

The present invention relates to a framework connection structure and connection method using a steel pipe and, more specifically, to a framework connection structure and connection method using a steel pipe, which are capable of easily constructing a framework by using a steel pipe without the use of a diaphragm. The framework connection structure using a steel pipe without a diaphragm, according to the present invention, comprises: inner reinforcement plates inserted into a steel pipe column so as to reinforce the inside of the steel pipe column; fixing nuts fixed to the inner reinforcement plates for preventing the rotation thereof before the inner reinforcement plates are inserted into the steel pipe column; outer plates coupled to the outside of the steel pipe column; and bolts coupled, from the outside of the steel pipe column, to the fixing nuts after penetrating the outer plates and side surfaces of the steel pipe column so as to integrally couple the outer plates, the steel pipe column and the inner reinforcement plates, wherein, when the outer plates are coupled to the outside of the steel pipe column in a state in which the outer plates are joined to beams, the steel pipe column and the beams become connected, and when the inner reinforcement plates and the outer plates are respectively coupled to the insides and the outsides of the connection parts of two steel pipe columns to be connected in a long manner, the steel pipe columns become connected to each other.

An embodiment of the present invention relates to an electronic mold counter device which uses an optical detection method to automatically count the mold production amount in a set time for higher working efficiency. The mold counter device comprises: a case mounted on a mold and having a shaft through-hole on one side thereof; and a counting unit disposed inside the case to count the number of press-fittings for the mold. The counting unit comprises a shaft which protrudes so as to penetrate the shaft through-hole. The electronic mold counter device comprises: an elastic member designed to be inserted into the case by an elastic force according to the mold press-fitting; an optical detection unit which detects the insertion of the elastic member by irradiating the inserted elastic member with light; and a calculation unit which counts the insertion operation of the detected elastic member as the number of press-fittings for the mold.
