A concrete form apparatus and system for connecting opposing form sections at a desired distance from each other defining a space to receive poured concrete, the apparatus preventing the form section separation, the apparatus including a locking pin, form connector rotatably and releasably affixed to a form, and retainer affixed to arm defining a channel therein sized to be engaged within the slot whereby the locking pin is placed through corresponding holes in adjacent forms and engages a first form, extends through the relative distance between the forms, exits through a hole in the second form, and the channel of the retainer attached to the second form engages the locking slot on the locking pin maintaining a fixed distance between the forms and preventing form separation when pouring concrete. A system using the foregoing and also including clamps for affixing adjoining forms to one another is also claimed.

A concrete form system including a barrier, a connection member, and a wall-base mold. In operation, two rows of barriers are connected with a connection member to define a channel for a concrete mixture. The concrete mixture is poured into the channel to form and set. The wall-base mold may be used to provide an additional extension to the channel used in construction. The wall-base mold is useful to aid in the construction of a residential building. The concrete form system is useful for providing a reusable concrete form.

A connecting clamp for template assembling includes: a left clamp unit (1) and a right clamp unit (2), wherein the left clamp unit (1) is rotatably connected to the right clamp unit (2) through a shaft (3); clamping faces (13) and positioning-correction faces (14) corresponding to frames (101) of templates (10) are provided at front portions of both the left clamp unit (1) and the right clamp unit (2); a fixer is provided at rear portions of the left clamp unit (1) and the right clamp unit (2), wherein the fixer enables the front portions of the left clamp units (1) and the right clamp unit (2) to grip the frames (101) of the templates (10). The present invention has advantages such as a simple structure, convenient use and adaptability to assembling of various templates.
