A composite wall assembly has an auxiliary wall and an inner wall. The auxiliary wall has a hollow space and a first supporting pillar having multiple first through holes. The inner wall is attached to the auxiliary wall and forms a depositing space. The inner wall has a first wall member, a second wall member, and a second supporting pillar having multiple second through holes. The depositing space is formed between the first wall member and the second wall member. The auxiliary wall provides a cushion effect and is not damaged easily in the earthquake for protecting the pipelines in the hollow space. The interior ambient temperature of the building is lowered by the hollow space of the auxiliary wall.

A retainer for securing conduit or wire to an opening in metal stud includes a pair of outer retaining portions for securing the retainer to the metal stud. Each outer retaining portion includes a groove for receiving an edge of a panel of the metal stud. An inner retaining portion includes a base connecting the pair of outer retaining portions to one another. The inner retaining portion further includes a pair of retention members defining a retention area therebetween in which a conduit can be secured. Each retention member includes a flexible arm. Each of the outer retaining portions extends away from the base to a free end.

A column bracket assembly is provided. The column bracket assembly comprises a bottom base bracket and a top base bracket, each including a bracket body adapted to receive an end of support element (e.g. a wooden column) and a mounting bracket/plate pivotally coupled to the bracket body and adapted to be coupled to a structural element (e.g. a footing, pile, header, beam etc.). The column bracket assembly optionally includes mounting brackets for installing cross brace brackets and/or tension rods to the bracket bodies. A method of installing the column bracket assembly, and a method of repairing, resettling, shoring, and/or leveling a structure with the column bracket assembly are also provided, along with structures comprising the column bracket assembly.

The present invention relates to a modular system of construction, conduction and fixation of tubular structure elements, comprising a first module (200), a second module (300) and, optionally, one or more additional modules (n), wherein each module (200, 300, n) comprises, in the region of its upper end, an annular fixing flange (230, 330) and crimp fins (240, 340) arranged inside the upper end at a fin distance (P.sub.240) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters. The crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5, times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300). The present invention also relates to a corresponding tubular structure (150).

A series of moment frames, each including two opposing spaced apart vertical legs and a horizontal crossbar connecting the top ends of the legs, are arranged linearly in spaced apart side-by-side array and opposing outer horizontal panel support beams are connected to the outside faces of the legs on each building side, offset below the crossbars. On the inside faces of the legs and running parallel to the beams, first and second opposing crane rails are attached. A bridge crane is mounted on the crane rails. Four-panel folding sections are assembled in an adjacent side-by-side array and rest on the panel support beams. Individual wall panels, arranged side-by-side, enclose the space from the bottoms of the legs (ground level) to the panel support beams. End panels, in various configurations, close the ends of the crane building and allow access doors or and other openings.

A drywall kit is provided including a wall frame, a drywall section, and a cabinet. The wall frame includes a top plate, a bottom plate, and a plurality of vertical studs. A first vertical stud includes a first hole and a first bolt screwed into the first hole. A second vertical stud includes a second hole and a second bolt screwed into the second hole. The drywall section includes a third hole which aligns with the first hole and a fourth hole which aligns with the second hole. The cabinet includes a back panel. The back panel includes a fifth hole which aligns with the first hole and a sixth hole which aligns with the second hole. The cabinet and the drywall section are secured to the wall frame via the first bolt and the second bolt. A method of installation is also provided.

A column assembly includes a two or more piece interlocking column assembly having at least a first linear section configured with an annular curve about a first short dimension, said at least first linear section having a first exterior surface, a first interior surface, and a first set of opposing edges, wherein said first set of opposing edges are configured with a first opposing male/female latch mechanism; and at least a second linear section configured with said annular curve about a second short dimension, said at least second linear section having a second exterior surface, a second interior surface, and a second set of opposing edges, wherein said second set of opposing edges are configured with a second opposing male/female latch mechanism, wherein said first opposing male/female latch mechanism and said second opposing male/female latch mechanism are configured to friction fit thereto each other.

A pre-tensioned centrifugal concrete pillar includes a concrete body, a steel cage including a plurality of pre-stressed rebars, a plurality of stirrups; and two plates, the rebars are steel strands, a plurality of conical through holes are provided on the plate, and multiple clips are disposed inside each conical through hole, each clip having a toothed inner surface, the multiple clips are spliced together to form a chock assembly for clamping each steel strand, and a peripheral surface of the chock assembly has a conical surface; a clamping hole is formed in the center of the chock assembly, the steel strand passes through a clamping hole and is clamped tightly. A method for manufacturing a pre-tensioned centrifugal concrete pillar is also included.
