A prefabricated formwork is disclosed. The prefabricated formwork of the present disclosure comprises at least one bracket comprising a first slot and a second slot, at least one first wall configured to be inserted into the first slot of the at least one bracket, and at least one second wall configured to be inserted into the second slot of the at least one bracket. The prefabricated framework may further comprise at least one support having at least one groove configured to receive the at least one bracket.

A separable integrated type vibration isolator includes: divided vibration isolator units comprising casings having accommodation spaces formed open on tops thereof and reinforced concrete comprising reinforcing bars arranged in the accommodation spaces and the connection spaces and concrete cast in the accommodation spaces; casing connection parts for connecting the casings of the divided vibration isolator units to each other; reinforcing bar connection parts for connecting the reinforcing bars exposed to the connection spaces of the neighboring divided vibration isolator units to each other; and fillers adapted to be cast in the connection spaces where the plurality of divided vibration isolator units is connected to form reinforced concrete.

An adjustable railing post-to-substrate embed system for anchoring a railing post having a railing base with plural railing base anchor holes includes: a plate, having anchor holes; a plurality of nuts, a first end of each nut being arranged proximate a respective one of the anchor holes, the first end of each nut being configured to be selectively and removably threadingly engaged, via the respective anchor hole, with one selected from the group consisting of: respective upper protective bolts, and respective bolts of the railing base; and a plurality of anchors, each being configured to adjustably threadingly engage a second end of a respective one of the nuts, distal the respective anchor hole, each of the anchors being individually adjustable in length by threadable engagement with the second end of the respective one of the nuts.

Embodiments described herein relate to construction of subsurface structural elements that are configured to redirect soil forces. For instance, a form may be used to construct a subsurface structural element such that the subsurface structural element redirects soil forces to vertically displace a foundation rather than have the soil forces crack or otherwise damage the foundation.

An internally braced permanent formwork for concrete foundation construction is provided in order to achieve a quick and simple assembly. The formwork comprises a base member laid on the ground having a perimeter recess on an upper surface for receiving components of the formwork. One or more permanent outer boards forming an outer periphery of the foundation are provided and coupled to a plurality of spaced internal bracing components to prevent collapse under the pressure of wet concrete.

A device for assisting to secure a bridge support bracket to a beam, the device comprising: a support frame, a hook to secure the support frame to the beam, a clamp to grasp and hold the bracket, and a pivot axle to pivotally connect the clamp to the support frame. When attaching at least two spaced apart such devices to the beam, then clamping a support bracket in each of the at least two spaced apart devices, both support brackets can be pivoted to a position where wood boards attached to the top of the support brackets are held in a not horizontal position. By then placing a wood stud in a position where it spans the two support brackets and attaching the wood stud to the respective bracket wood boards, a workman can then further pivot the support brackets to where the wood boards extend horizontally away from the beam.

A single-use or multi-use prefabricated pier top form for topping a concrete pier comprises a hollow mold with an upper portion in the desired shape of the finished pier top, a stepped-down tapered mid portion, and a lower mating portion for mating with the pier form so that concrete can be continuously poured to fill both the pier form and the pier top form at one time. Use of the prefabricated pier top form results in substantial time and material savings because the top of the pier residing above ground can be formed at the same time as the footer and pier are formed replacing the need to form a separate pier top after the pier and footer have been filled with concrete.
