A horizontal support apparatus and method are provided for use with any structure having a horizontal span, including but not limited to doors, garages, and windows. The horizontal support apparatus may include two support columns, a lintel that is configured to be attached to the support columns, and that includes a vertical flange and a horizontal flange. The apparatus may include two lift bolts coupled to two end portions of the horizontal flange. The two lift bolts may be configured to respectively raise the two end portions of the horizontal flange.

Apparatuses and methods for accurately applying an architectural layout to a surface. A calibration system includes a calibration rig having a plurality of vertical calibration legs assembled with a plurality of horizontal calibration legs and a laser that emits one or more beams of light onto a work surface to position the architectural layout relative to the calibration rig on the work surface. Calibration markers are positioned at intersections of the vertical and horizontal calibration legs for the laser to scan and confirm calibration accuracy of each of the calibration markers. The calibration markers calibrate the laser by using fixed, known points on the calibration grid that can be folded, collapsed, disassembled, and/or rolled for easy transport to other locations. The work surface can include obstacles and/or be uneven.

An apparatus guides first and second assembly components into a predetermined configuration, each assembly component including an opening. When the assembly components are aligned into the predetermined configuration, their openings align to define a cavity for receiving a stepped dowel to fasten the components together. The guiding apparatus includes a stepped dowel member having successively-smaller dowel sections, and a collar member floating around the base of the stepped dowel member. The stepped dowel member tip can be passed through the first assembly component opening and inserted into the second assembly component opening, drawing the components into the predetermined configuration. When the components are aligned into the predetermined configuration, the collar member engages the first assembly component opening and the stepped dowel member engages the second assembly component opening. The guiding apparatus can be disengaged, freeing the dowel-receiving cavity to accept a stepped dowel for fastening the assembly components together.

The present invention relates to a device for connecting and separating masonry units, preferably bricks, which comprises a tubular body that fits the tubular shape of holes in the bricks. The device for connecting and separating comprises a portion that has a straight cross-section larger than the cross-section of the tubular body and disposed approximately midway along the length of the connector device, for separating the bricks that said device connects. The device also comprises at least one depression or channel along the entire length of the tubular body, the depression or channel acting as a spring. The connector allows walls to be assembled using only bricks and connectors so as to apply mortar ex post.

Portable apparatus for application of double-sided sheet adhesive to modular flooring products, includes a planar platform; a flooring guide; a roll of double-sided sheet adhesive unrolled onto the platform for marrying with the modular flooring product; a sheet adhesive guide to maintain the sheet adhesive in alignment with the flooring guide and the modular flooring product, and to tension the sheet adhesive as it is applied to the flooring product; and a press roll to apply pressure to mate the sheet adhesive to the flooring product.

A modular connector system is designed and configured for setting various building material members in place prior to construction of a wall. The modular connector system includes a base plate, a vertical riser member, at least one horizontal arm, and a connection member for each of the at least one horizontal arms. The base plate is configured to support the modular connector system. The vertical riser member is affixed to the base plate in a vertical orientation. Each of the at least one horizontal arm is configured to be adjustably positioned along the vertical riser member. The connection member on each of the horizontal arms is configured to attach to one of the building material members. Wherein, the disclosed modular connector system is designed and configured for setting the building material members in place prior to construction of the wall.

A levelling structure for levelling a structure having supports for secondary support on fixed footings. A coupling mechanism extends between an access point on the structure and the footings. Adjustment of the coupling member from the structure alters the elevation of the structure and supports together towards or away from the footings. By providing the adjustment from the structure itself, the requirement for elevational adjustment beneath the structure is avoided as well as adjustment against the opposition of the load.

The disclosure relates to the technical field of building structure engineering, in particular to a longitudinal seam caulking and monitoring restore device and a longitudinal seam caulking restore method. The longitudinal seam caulking and monitoring restore device includes: a first panel, on which a plurality of guide seats are arranged; a second panel, which is arranged to be opposite to the first panel; stranded wires, which are wound on the guide seats, wherein first ends of the stranded wires are connected to stranded wire end seats, the stranded wire end seats are fixedly connected to the second panel, second ends of the stranded wires extend out of a space between the second panel and the first panel and are connected to fastening devices, and the fastening devices are capable of tightening and releasing the stranded wires; a plurality of elastic components, wherein the elastic components are arranged between the first panel and the second panel, first ends of the elastic components are fixedly connected to the first panel, and second ends of the elastic components are fixedly connected to the second panel; and two groups of air columns, wherein a connection line of one group of air columns intersects another connection line of the other group of air columns to form a cross, each group of the air columns includes at least two air columns.

The present disclosure relates to a method and system for forming and laying out a substantially perfect ninety degree angle that is used to form the corner of a construction footprint.

The invention relates to a device for aligning building blocks, comprising a connecting element and a base plate which is connected to one end of the connecting element, wherein the base plate extends from two opposite sides of the connecting element in a perpendicular manner or in an angle slightly less than perpendicular. The device further comprises a wedge receiving plate which is connected to the other end of the connecting element, is substantially in line with the connecting element and comprises an opening designed for receiving a wedge. The base plate and the wedge receiving plate are each connected to the connecting element via a frangible joint. Upon application of the device, the base plate, the wedge receiving plate and the wedge together squeeze the building blocks together so that they become aligned. As a last step, the base plate and the wedge receiving plate are broken off from the connecting element to leave the connecting element between the building blocks.
