A rapidly erectable, removable, reusable, and raisable acoustical wall system is provided that comprises a plurality of wall panels, each of which has opposing side edges which include a front edge and a back edge, a plurality of panel support posts having pairs of parallel flanges for receiving the side edges of the wall panels to form a wall, and a plurality of wedging members for forcefully securing the front side edges of the panels into an acoustically-obstructing engagement with the front flanges of the panel support posts. Wedge-receiving recesses are provided at the top and bottom of each of the back side edges of the panels, the top recesses of one panel being registrable with the bottom recesses of another panel when two panels are stacked between the same support posts. Each wedging member is about the shine length as two aligned wedge-receiving recesses so that a single wedging member may be used to forcefully engage the front side edges of two different panels against the front flanges of their respective support posts. In the apparatus of the invention, the erection of the walls is expedited by the wedging members, which function to forcefully engage the bottom half of a wall panel into acoustically-obstructing engagement with its respective support post simply by the act of stacking one wall panel over another. Additionally, the resulting wall may be easily raised at another location by mounting extension members on the tops of the support posts, and sliding additional wall panels between the heightened posts.

Rapidly erectable, removable, reusable and raisable outdoor acoustical

A system and method for adjustably connecting traffic barriers and pre-cast wall facing panels to the soldier beams of a pile wall is provided, which includes a connecting structure cast-in-place between the upper ends of the beam and the panels for structurally interconnecting both a traffic barrier and the upper ends of the panels to the beam. The system further includes an anchor member projecting from the upper end of the soldier beam for securing the connecting structure to the beam, as well as a depth-adjustable array of reinforcing members that are cast within the structure for accommodating variations in the distances between the beams and panels. At least one of the array of reinforcing members projects upwardly out of the connecting structure to link the traffic barrier to the connecting structure. In the method of the invention, the connecting structure is cast-in-place on top of a connecting column that secures the wall panels to the soldier beams, and the traffic barrier is in turn cast over the connecting structure after it sets.

System and method for adjustably anchoring traffic barriers and wall

A rapidly erectable, removable, reusable, and raisable acoustical wall system is provided that comprises a plurality of wall panels, each of which has opposing side edges which include a front edge and a back edge, a plurality of panel support posts having pairs of parallel flanges for receiving the side edges of the wall panels to form a wall, and a plurality of wedging members for forcefully securing the front side edges of the panels into an acoustically-obstructing engagement with the front flanges of the panel support posts. Wedge-receiving recesses are provided at the top and bottom of each of the back side edges of the panels, the top recesses of one panel being registrable with the bottom recesses of another panel when two panels are stacked between the same support posts. Each wedging member is about the same length as two aligned wedge-receiving recesses so that a single wedging member may be used to forcefully engage the front side edges of two different panels against the front flanges of their respective support posts. In the method of the invention, the erection of the walls is expedited by the wedging members, which function to forcefully engage the bottom half of a wall panel into acoustically-obstructing engagement with its respective support post simply by the act of stacking one wall panel over another. Additionally, the resulting wall may be easily raised at another location by mounting extension members on the tops of the support posts, and sliding additional wall panels between the heightened posts.

A form system and method is provided that is capable of molding pre-cast, structural wall panels of different lengths, widths, thicknesses and architectural finishes for a variety of different types of wall systems. The form system comprises a base assembly formed from at least one rectangular base, a plurality of form liners supportable by the base assembly for defining the bottom of a mold space and for imparting different architectural finishes to panels molded thereby, a pair of elongated side wall members for defining the sides of the mold space, a plurality of vertically-oriented slots and bolts in each of the elongated side wall members for adjustably mounting these members at different heights with respect to the base assembly, an alignment flange on the inside surfaces of each of the side wall members engagable against the side edges of the selected form liner for aligning each of the side wall members to a proper height with respect to the form liner, and end wall members detachably connectable between the two side wall members for defining the end walls of the mold space. The system of the invention is capable of molding panels for mechanical stabilized earth walls, acoustical walls, pile and lagging walls, or post and panel walls quickly, reliably, and dimensionally consistently with only a relatively few easily adjustable components.

Single form system and method for molding pre-cast structural wall

A system and method for adjustably connecting pre-cast wall facing panels to the soldier beams of a tie-back or anchor wall is provided, wherein the system comprises an array of panels stacked in rows having mutually adjacent side edge portions which are spaced apart from one of the soldier beams, a connecting column cast-in-place between the beam and the adjacent side edge portions of the panels for structurally interconnecting both of the panels to the beam, and an adjustable array of reinforcing members within the column for interconnecting the adjacent side edge portions of each of the panels with the beam and for reinforcing the resulting column. The depth of the cast-in-place connecting column advantageously accommodates variations in the distances between the beams and panels. In the method of the invention, a first row of wall facing panels is stacked in front of the soldier beams, and a first section of the connecting column is cast therebetween. Thereafter, a second row of panels is stacked on top of the first, and the process repeated until the wall achieves its desired height. Both the system and the method are particularly applicable to tie-back walls employing piles since the cast-in-place connecting column automatically adjusts for misalignments between the piles and the wall facing panels.
