TRACK SYSTEM FOR SUPPORTING WALL STUDS
An apparatus for supporting and retaining a plurality of parallel spaced apart wall studs comprises a longitudinally extending base having first and second side edges and first and second opposed sidewalls extending generally perpendicular to the base from the first and second side edges, wherein the base and sidewalls together define a trough for receiving and retaining an end portion of the plurality of wall studs. The apparatus further comprises a plurality of clips sized to fit within and extend transversely across the trough, each of the plurality of clips having first and second tabs extending from the base wherein the first and second tabs each define a slot with a corresponding of the first and second sidewalls sized to receive a portion of the wall studs therein.
TEMPORARY POOL COVER AND FLOOR SYSTEM
The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.
Lintel support, masonry support kit, and lintel support method
The present invention includes a lintel support to aid in lintel repair and/or reinforcement. The lintel support has a body with a top, a bottom, and a height extending therebetween; at least one claw at the top; and a bracket at the bottom. In use, points are dug out of a mortar line above the lintel and the claws of the lintel support are positioned into those points. With the claws so positioned, the bracket will be below the failing lintel. A support beam is placed under the bracket and a jack lift provides uplift at the mortar line where the claws are positioned.
I-SHAPED STEEL WITH DISCONTINUOUS TOP FLANGE REINFORCED COMPOUND CONCRETE BEAM CONTAINING DEMOLISHED CONCRETE LUMPS AND CONSTRUCTION PROCESS OF SUCH BEAM
An I-shaped steel with discontinuous top flange reinforced compound concrete beam containing demolished concrete lumps and a construction process thereof. The beam comprises an I-shaped steel having discontinuous top flange, longitudinal bars (7), stirrups (6), waist bars (8), fresh concrete (5), and demolished concrete lumps (4). The I-shaped steel having discontinuous top flange consists of a bottom flange plate (3), a web (2) and a discontinuous top flange plate (I). The discontinuous top flange plate (1) consists of two rectangle steel plates or trapezoid steel plates located at both sides of the I-shaped steel. The two steel plates have a same length that is one third of a length of the I-shaped steel. The trapezoid steel plate has a width of a short side no less than a quarter of a width of the long side. The recycled compound concrete beam saves steel, fully uses the demolished concrete lumps, and is convenient to construct.
