CONNECTION MEMBER FOR RETAINER FORM Russian patent published in 2005 - IPC

FIELD: building, particularly for erecting outer and inner cast-in-place walls of building and building structures.

SUBSTANCE: connection member comprises two parallel lay-on cradle members arranged on one level. Cradle members have side walls for form panel receiving and transversal anchor tie for cradle members connection. Distance between cradle members is equal to thickness of wall to be erected with the use of above form. Distance between side walls of each cradle member is equal to form panel wall thickness. Anchor tie is made as connection member located transversely to cradle members. Connection member is rod constituted of two parts to adjust length thereof within the given range by mutual moving rod parts along rod axis and by relative fixation thereof. One rod part has blind axial hole and inner annular bead located at hole edge. Another rod part has a number of coaxial outer annular beads spaced equal axial distances and divided by annular grooves. Each groove has width equal to that of inner annular bead of the first rod part. Annular beads formed in the second rod part have equal diameters exceeding inner diameter of inner annular bead and equal to that of axial hole of the first rod part. Inner annular bead and/or outer rod beads are made of resilient material. Elasticity of above material and bead shapes are selected to provide one by one passage of outer annular beads of the second rod part through inner bead of the first one to stepwise reduce rod length up to predetermined value. Above length adjustment is performed by applying predetermined axial adjusting force to rod along with preventing mutual axial displacement of rod parts after force removal.

EFFECT: reduced of costs of connection member production, transportation and storage, reduced labor inputs for connection members arrangement on form panels and reduced material consumption.
