The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.

Disclosed is an economical and effective way of producing a modular retaining wall for a material to be retained, using backer blocks and facing blocks which are stacked into continuous front and back wall components connected by separate connectors in a back to back, spaced apart arrangement, thereby forming a hollow retaining wall. The hollow wall is filled with loose filler material to increase the mass and retaining capacity of the wall. None of the wall components is embedded in the material to be retained. The facing blocks, connectors and filler material are all separated from the material to be retained by the backer blocks. Further disclosed are wall components and a wall kit for a modular retaining wall. A double sided decorative wall is also disclosed. The modular wall system allows for the construction both straight and curved retaining walls.

Various embodiments of the present disclosure provide a curb wall forming apparatus and method for forming a curb wall without causing damage to the adjacent concrete floor. In various embodiments, the curb wall forming apparatus includes one or more floor plates, one or more curb side wall forming panel supports, one or more stanchions, one or more end plates, one or more wall attachment plates, and one or more curb side wall forming panels which are used together to enable a curb wall to be formed. These components can be used together to enable a curb wall to be formed on a floor adjacent to an upstanding wall without causing damage to the wall or the area of the floor adjacent to the formed curb wall. The floor plates, the curb side wall forming panel supports, the stanchions, the end plates, and the wall attachment plates remain as part of the formed curb wall.

A concrete wall formwork module is provided in which the lateral and longitudinal opposite side edges of the modules are provided with complementary shapes that lock in place two adjacent modules when they are both deployed. The opposite side edges of adjacent modules interlock in one direction and are configured for adjoining according to a shiplap arrangement in the other direction.

Disclosed is an economical and effective way of producing a double sided wall having a corner or closed end using facing panels having a face surface and a back surface with a retaining structure. The facing panels are stacked in a back-to-back arrangement into a pair of first and second wall components bridged by separate connectors. An end wall component forming an end or corner of the wall includes facing panels stacked to extend across the intermediate space. A branched connector and link are used for bridging a concrete facing panel in the end wall component with an adjacent concrete facing panel of the first or second wall component. The branched connector has a first connecting end and an opposite branched end with at least a pair of second connecting ends for attachment to the retaining structure of the adjacent facing panel and the link has a first end for attachment to a facing panel in the end wall component and a second end for linking to the branched connector.

A corner form panel used in an insulating concrete form system includes a hinged corner web member at least partially embedded in each of two segments of the form panel. The hinged corner web member enables the two segments to rotate with respect to each other, so that the form panel can be opened to a flat configuration for shipping, and folded into a corner configuration at the jobsite. Both inside and outside corner panels may be provided, and may use different hinged corner web members. The corner web member may include features for connecting the inside and outside corner panels, to reinforce the resulting form unit.

Disclosed is a method for preparing a concrete-filled steel tubular edge-constrained laminated shear wall, belonging to the field of prefabricated buildings. The method allows for integrated hoisting during installation, leading to a simple working procedure and easy quality control. During manufacturing, an interior wythe board is flipped and placed on supporting members on rectangular steel tubes, no cavity formwork or bracket is needed in a cavity, and thus an operation of pulling out the cavity formwork is avoided, and high production efficiency is achieved. The rectangular steel tubes can be welded to horizontal steel bars of interior and exterior wythe boards, avoiding the cumbersome working procedure and high cost caused by stud connection while achieving reliable connection and direct force transmission.

Disclosed herein is an earthquake-resistant rammed earth structure. The earthquake-resistant rammed earth structure includes an armed scaffold located inside a rammed earth wall. The armed scaffold includes a foundation at the bottom, a bond beam at the top, two concrete columns at two respective corners extending from the foundation to the bond beam, a mesh network with a zigzag arrangement continuously extending from the foundation to the bond beam, a strand of barbed wire perpendicularly woven into the mesh network, a plurality of parallel vertical rebars extending from the foundation to the bond beam, a plurality of parallel horizontal rebars extending between the two concrete columns, a plurality of U-shaped fasteners fastening the plurality of vertical rebars, the plurality of horizontal rebars, and the mesh network together, and a plurality of transverse connectors transversely interlocking the rammed earth wall and the armed scaffold.

A tri-layer steel reinforced concrete (S3RC) building structure comprises a steel frame, at least one steel shell layer, multiple rebars, and a concrete. The steel shell layer is mounted on the steel frame. The rebars are connected to the steel frame and located at one side of the steel shell layer. The concrete is mounted at the side of the steel shell layer and embeds the rebars. With the steel shell layer and/or the steel frame cover the concrete and the rebars, a tensile resistance of the concrete may be enhanced from the exterior, increasing the earthquake resistance. If the earthquake occurs and the concrete is shattered, the broken pieces may be covered by the steel shell layer rather than fall apart, avoiding collapse of the overall structure. Besides, the steel shell layer can also protect the concrete from being affected by the atmosphere and moisture, preventing the concrete from bulging and weathering.
