A seal for a lead-through for a tie rod through a panel formwork element. The seal includes a sleeve, a sealing element and a sliding tube, which are disposed on the tie rod and, together with the tie rod, are placed through the panel formwork element from a rear side, so that the sealing element exits the panel formwork element on a front side and, after brief pulling back of the tie rod, provides sealing between the sleeve and the panel formwork element, for one-sided anchoring.

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

Anchor assembly for a vertical formwork that according to one embodiment includes a front anchor element and a tie rod having a first end that is housed in the front anchor element. The front anchor element and the first end of the tie rod are configured for fixing the front anchor element in different axial positions of the first end of the tie rod, such that when the tie rod is arranged in a fitting angular position it can move axially with respect to the front anchor, and when the tie rod is arranged in a fixing angular position the tie rod cannot move axially with respect to the front anchor. According to some embodiments the front anchor element also includes blocking means configured for blocking the rotation of the tie rod when it is arranged in the fixing angular position.

According to one embodiment a rear anchor assembly for a vertical formwork is provided that includes a dome plate having a spherical-shaped central section. The dome plate has an opening that extends through the spherical-shaped central section. The rear anchor assembly also includes a nut with a threaded hole configured for housing a threaded end of a tie rod. The nut includes a spherical portion arranged in the opening of the dome plate. The spherical portion of the nut and the spherical-shaped central section of the dome plate are coupled like a ball and socket joint. The rear anchor assembly also includes a support plate configured for being fixed to a rear formwork panel, the support plate including a housing in which the dome plate is arranged, the dome plate having freedom of radial movement with respect to the support plate inside the housing.

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.

Systems and methods for modular walled systems, such as modular walled spas and modular walled privacy fences and can protect pool and spa equipment from the public. In one embodiment, the modular walled system includes an outer frame disposed within a medial frame, and an inner frame disposed within the medial frame, wherein each frame includes a set of brace assemblies that connect to rebar grids. The brace assemblies may include a foot plate and threaded couplers. The wall system also provides protective room for electrical raceways and a secure anchor substrate to attach electronics, panels, boxes or lighting systems.
