The present invention relates to a design structure of an apartment house in which a plurality of apartment units, each of which is a maisonette in which two floors including an upper floor and a lower floor are combined into a single apartment unit, are repeatedly arranged in vertical and horizontal directions, wherein, in the design structure, each apartment unit has a living room disposed on the upper floor and a plurality of bedrooms disposed on the lower floor, double pillars spaced apart from each other are installed on side boundaries of adjacent apartment units, the double pillars include a pair of first pillars disposed inside an apartment unit and a pair of second pillars disposed outside the apartment unit and disposed inside another apartment unit adjacent thereto, a first beam member, which serves as a structure carrying a load, is connected to and installed at the first pillar, a second beam member, which serves as a structure carrying a load, is connected to and installed at the second pillar, and a double pillar connecting beam configured to connect the first pillar and the second pillar is additionally provided on a side surface of a slab of the lower floor.

A round pocket isolating form is placed around column footer before a concrete form is poured, to keep concrete away from anchor bolts protruding upward from the footer. A round lid for the form is also disclosed.

According to a resilient platform assembly, a playing deck includes a plurality of horizontally disposed deck panels. Each deck panel of the plurality of horizontally disposed deck panels has a pair of foot flanges on the bottom of the deck panels. Receiving shoes are attached to the deck panels. The receiving shoes are configured to receive the foot flanges of the deck panels. A transverse member is perpendicular to the plurality of horizontally disposed deck panels. The transverse member includes a plurality of notches. Each notch of the plurality of notches is cut in the transverse member in a predetermined spacing pattern. The receiving shoes are installed in the notches and the deck panels are attached to the transverse member through the receiving shoes. Resilient mounts connect the transverse member to a support assembly and allow relative motion between the transverse member and the support assembly.

A cross-laminated timber panel comprises a plurality of layers of lumber boards, each layer comprising a number of the lumber boards laid side-to-side pointing to a direction, each layer being disposed perpendicular to the direction of an adjoining layer; and an insert member replacing one of the lumber boards, the insert member having a different material or configuration than the lumber boards.
