The present invention relates to a support post (2) comprising at least two tubes (4, 6) telescopically in sliding connection to each other. A locking device (8) holds the tubes in a locked state and allowing relative sliding of the tubes in an unlocked state. At least one end (10) of the support post has an opening (12; 112) in connection with a surface support element (14; 114). A spring is arranged within the opening of the support post to act on the surface support element (14; 114), to resiliently affect the surface support element (14; 114) in a direction away from the open end (10) of the support post and vice versa. The locking device (8) comprises a locking ring loosely arranged on one of the tubes (4) and further comprises a first ring holding arm arranged at one end of the other tube (6); the first ring holding arm having a first recess for retaining the locking ring in loose arrangement around said tube (4) with limited movability. A lever is in engagement with the spring and arranged in a first position in an unstressed condition of the spring. The lever is arranged in a second position in a stressed condition of the spring. By moving the lever from the first position to the second position, and vice versa, resiliently affect the surface support element (14; 114) in a direction to and from the open end (10) of the support post (2). The surface support element is arranged to be installed on a floor, and the lever is a pedal.

A modular pipe brace assembly is provided for supporting a concrete wall panel, where the modular pipe brace assembly has a plurality of brace sections that each have a pipe with one of at least two standard lengths and a connection plate attached to each end of the pipe. At least two of the plurality of brace sections are attached together in longitudinal alignment by engaging the connection plates to define a pipe assembly with a desired length. An adjustable shoe assembly is attached to each end of the pipe assembly and is configured to engage a ground anchor or a concrete wall panel. The plurality of brace sections may, for example, include a low-load brace section that has a low-load capacity pipe and a high-load brace section that has a high-load capacity pipe.

A foundation structure is made up of a screw that is vertically adjustable into a pile to a desired height, a ball joint connected to the screw, and load bearing components that can be adjusted on the ball joint in 3-dimensional space with respect to the position of the pile. The load bearing components include at least two plates that, between them, define a hollow slot into which an anchor bolt can be held in place vertically while still having allowance for lateral motion. A load bearing plate at the top of the structure can be laterally translated based on movement of the anchor bolt. The load bearing plate is removably couplable to the floor of a building. The structure allows for vertical, lateral, and angular adjustment, providing tolerance for foundation misalignments due to inconsistencies inherent to topography and/or offset between an intended and an actual point of installation.

An elastic clamp is for coupling props to beams. The clamp includes a minimum of two elastic wings able to hold and exert pressure on opposite lateral faces of the beam to be supported by the prop. The clamp allows the prop to be retained in a place selected along the beam to be supported, and prevents the prop from falling and rotating sideways.
