Retaining Wall Expansion Joint In Concrete Block Wall

Construction joints in retaining walls.

Retaining wall expansion joint in concrete block wall.

Expansion joints should be located at intervals up to 90 feet. Exterior vertical wall expansion joint selection guide emseal watertight fire rated sound proof insulating precompressed foam sealant expansion joints. This temperature variation causes expansion and contraction in the structure. Expansion joints are provided in every large structure which is subjected to high variation in temperature during its lifetime.

Other constru c tion joints coincide with or function as contraction or expansion joints. They may be vertical and horizontal. Construction joints separate the work of the concrete being poured at different times. The main board construction for retaining walls.

The provision of movement joints depend on the lengths of walls. For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on centers. Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3. Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together.

Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes. Details of this butt type con s t r uction joint are shown in figure 4. S t r uction joint restricts wall move ments and should be as strong as the wall without joints. While these attributes are the primary basis for concrete masonry s.

Or possibly where joining new to existing retaining walls also require weep holes at the base of the wall to prevent water pressure building up behind the wall. As a rule of thumb it is normal to consider movement joints at approximately 6 m centres in straight lengths of autoclaved aerated concrete block walls. An information series from the national authority on concrete masonry technology ncma tek 10 2c 1 control joints for concrete masonry walls empirical method introduction concrete masonry is a popular construction material because its inherent attributes satisfy the diverse needs of both exterior and interior walls. Expansion joints are provided to allow th.

These joints may be filled with flexible joint fillers.
