An anchor bolt fastener assembly with specialized connection capabilities and features for attaching building components to concrete slabs, walls, ceilings, and/or structural surfaces. Compression force can be established and maintained over time using a compression washer in combination with a specialized fastener stud that is designed to exploit the compression washer benefits. Methods of using exemplary embodiments include installing the anchor bolt fastener assembly relatively flush with the surface of the concrete slurry by direct insertion in the slurry using a specialized threaded anchor bolt float. Once the slurry hardens, the anchor bolt and anchor bolt float embedded in the concrete slurry cooperate with the specialized fastener stud to secure the building component to the concrete.

An alignment tool and method that is easy to use during the installation of a base of a commercial storage rack over bolts extending up from a warehouse floor. The alignment tool comprises a cylindrical body having a first conically shaped upper end and a second lower end having a bolt receiving hollow opening therein. The opening extends up into said cylindrical body along a longitudinal axis of the body. The method includes placing the opening down over the bolts, with the conical top facing up, to protect the bolts and align the base as it is lowered over the bolts. The alignment tool can be easily removed, prior to bolting the base to the floor, such as with a removal tool through a hole in the alignment tool.

A fastener assembly comprises a first cylindrical member disposed within a second cylindrical member. One of the first and second cylindrical members is movable relative to the other in a first direction. The other one of the first and second cylindrical members is locked relative to the one in a second direction opposite to the first direction. A spring is operably attached to the first and second cylindrical members to urge one of the first and second cylindrical members in the first direction. A removable member is operably associated with the first and second cylindrical members to prevent one of the first and second cylindrical members from moving in the first direction prior to removing the removable member. The removable member is configured to be pulled out to allow one of the first and second cylindrical members to move in the first direction.

A prefabricated wall for a prefabricated building includes a concrete body and a rigid framework arranged inside the poured concrete body, the rigid framework comprises n longitudinally extending vertical rebars, with n being an integer greater than or equal to three; an upper end face and a lower end face of the prefabricated wall are formed with m mechanical connection portions at positions sharing the same axes as the vertical rebars, with m being an integer less than or equal to 2n; and the mechanical connection portions are all formed at end portions of the vertical rebars. An assembly structure for a prefabricated building is further provided. The assembly structure is formed by filling an assembly gap with an on-site poured layer after rebars are firmly connected at an overhead region between an upper-layer wall, a lower-layer wall and a floor slab by means of fastening components.

The invention relates to a modular plant (1), in particular a modular industrial plant, comprising a plurality of cuboid-shaped plant modules (20, 40, 40a, 40c), which are arranged in two or more layers stacked one above the other. The modules have a support structure having fastening points (24, 24″, 44, 44″), wherein the fastening points are provided for connecting a module to corresponding fastening points of the adjacent modules of a layer located above and/or below thereof. In the horizontal plane, the modules of a layer are connected to the adjacent modules of the layer located above and/or below thereof in a form-fit manner by means of a connection element (64) having the shape of a double cone or of a double conical frustum. At least one traction device (62, 70, 80) having a tension member (62) is provided, by way of which traction device a bottom layer of modules (40a) or a foundation block (6) can be impinged upon with a tensile force along the vertical, with respect to a top layer of modules (40c) such that along the vertical, the modules between said bottom layer (12) and said top layer (11) and the adjacent modules of the layer located above and/or below thereof are positively pressed together at the fastening points and are thus fixed in place.

The fully eccentric inner sleeve includes a first outer diameter and a first inner diameter. The first inner diameter of the fully eccentric inner sleeve is configured to receive an anchor bolt. The fully eccentric outer sleeve includes a second inner diameter and a second outer diameter. The second inner diameter is configured to receive the first outer diameter of the fully eccentric inner sleeve. The second outer diameter is configured to insert into an opening in a sill plate of a wall panel. A wall is also provided. The wall includes an anchor bolt, a fully eccentric inner sleeve, a fully eccentric outer sleeve, and a sill plate. A method of installing the wall is also provided.

This invention, the Anchor Bolt Setter mechanism assembly, is designed to attach to various different types of pre-erected foundation forms in order to properly set anchor bolts to code specifications before the concrete is poured. The Anchor Bolt Setter (“ABS”) is robust and strong in order to withstand the force of pouring concrete. The ABS consists of different styles of ABS Sliders to correspond with the different styles of foundation forms along with an ABS Elbow to accommodate when the concrete is not poured to the top of any foundation concrete forms, and it includes different styles of ABS Bolt Caps that correspond with the different sizes of anchor bolts. The suspending of an anchor bolt before concrete is poured is achieved by the Anchor Bolt Setter mechanism assembly. An anchor bolt is threaded into one of the corresponding ABS Bolt Caps, and then one of the ABS Sliders or the ABS Elbow is mounted to a concrete foundation form and then the Bolt Cap is locked onto any of the ABS Sliders or the ABS Elbow which properly sets and suspends the anchor bolt holding it from moving during the pouring of concrete. This practice properly sets anchor bolts for concrete foundations and eliminates the practice of wet setting anchor bolts.
