20150197898 | CONCRETE DOWEL SYSTEM - A dowel placement system including a fastener configured to be engageable with a form, and a radially compressible bushing coupled to the fastener and defining an adjustable outer diameter. The system further includes an elongate dowel sleeve having opposed proximal and distal end portions, and an axial opening having an inner diameter and extending into the dowel sleeve from the proximal end portion to the distal end portion. The bushing is insertable within the axial opening of the dowel sleeve, and the bushing and dowel sleeve are configured such that insertion of the bushing within the dowel sleeve causes the outer diameter of the bushing to compress and conform to the inner diameter of the dowel sleeve and to create a friction force between the bushing and the dowel sleeve to mitigate movement of the dowel sleeve relative to the bushing during formation of the concrete structure. | 07-16-2015 |
20150052842 | ARCHITECTURAL CONCRETE AND METHOD OF FORMING THE SAME - A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture. | 02-26-2015 |
20140248076 | SLIP DOWEL SYSTEM - Provided is an improved concrete dowel placement apparatus having a base member including a base plate that is disposable on the outer surface of the concrete form, and an extension member that extends through an aperture located within the concrete form. In this regard, the base member is supported by the concrete form, and is therefore generally configured to withstand higher loads than the conventional prior art designs. Furthermore, the particular attachment configuration spaces the base plate from the concrete slab, which generally prevents the base member from becoming embedded within or adhered to the concrete. As such, removal of the form from the cured concrete tends to be much easier than removal of conventional prior art systems. In addition, the base member is less likely to crack or break during removal, which reduces the overall cost, as fewer base members may need to be replaced. | 09-04-2014 |
20140245694 | ARCHITECTURAL CONCRETE WALL AND METHOD OF FORMING THE SAME - Provided is a method of forming an architectural concrete wall. The method includes conveying a concrete mixture onto a base surface and floating the concrete mixture. The method further includes providing an elongate irregular surface forming tool having a gripping portion and a distressing portion defining an irregular configuration. The exposed surface is repeatedly struck with the distressing portion of the irregular surface forming tool to define an irregular surface. | 09-04-2014 |
20130209166 | SURFACE DRAINAGE SYSTEM - A surface drainage structure formed above a subgrade may include an elongate drain conduit disposed partially within the subgrade. The elongate drain conduit may define at least one drain slot extending through a wall thereof. The structure may include a pavement layer with an exposed top surface and a drainage channel extending therefrom. The drainage channel may be in fluid communication with the drain slot of the elongate drain conduit. A method of forming the surface drainage structure includes placing the elongate drain conduit in the subgrade, forming the pavement layer, cutting an upper channel along the elongate drain conduit, and cutting a lower channel and the drain slot in the elongate conduit. | 08-15-2013 |
