[0002] Before pouring concrete, the formwork needs to be assembled and connected. At the corners, the two adjacent frames need to be connected as a whole using connectors to ensure that the poured wall is a whole.
[0003] The corner connectors currently used are mostly angle steels, with connection holes opened on the two straight sides of the angle steels, and then connected by bolts. However, there is a problem with using angle steels: in order to ensure the structural strength between two adjacent frames and the strength of the connector itself, thicker angle steels are needed to compensate for the strength, but this increases the weight of the connector itself, which causes high labor intensity for construction workers and is very strenuous during operation, which further results in a decrease in construction efficiency.
[0004] Therefore, there is an urgent need for concrete formwork corner connectors and concrete formwork components to solve the above-mentioned technical problems. Utility Model Content
[0005] In view of the above technical problems, the utility model provides a concrete vertical formwork corner connector and a concrete formwork assembly, which are used to solve the problem that the existing formwork corner connectors are heavy, cause high labor intensity for construction workers and affect construction efficiency.

[0021] (4) By providing a rib plate between the two first pin holes, interference of the rib plate with the pin is avoided.
