[ detailed description ] embodiments
Referring to fig. 1 to 5, the composite moisture-proof wooden door of the present invention comprises two door panels 8 and a framework located between the door panels, wherein the framework is rectangular and comprises two
a transverse rod cavity and a longitudinal rod cavity which are formed by hollow structures are respectively arranged in the
the wooden door also comprises a
the
the
the transverse stress rod and the longitudinal stress rod are screwed and moved for a certain displacement amount towards the transverse rod cavity and the longitudinal rod cavity respectively, so that the transverse rod and the longitudinal rod are subjected to certain tensile stress respectively.
The outer ends of the transverse stress rod and the longitudinal stress rod are respectively provided with an inner hexagonal interface, and the transverse stress rod and the longitudinal stress rod can be screwed by aligning the inner hexagonal interfaces with a torque wrench or a screwdriver.
The cross sections of the transverse rod cavity, the longitudinal rod cavity, the transverse stress rod and the longitudinal stress rod are all circular.
The magnitude of the tensile stress of the transverse rod and the longitudinal rod is judged by the screwing angle of the transverse stress rod and the longitudinal stress rod.
Since the cross-sections of the transverse bars and the longitudinal bars are identical or similar, and therefore the linear expansion of the two is considered to be identical, the longer bar body has a greater total deformation and therefore requires a greater prestress, i.e. the longer of said transverse bars and longitudinal bars is subjected to a greater tensile stress than the shorter of said transverse bars and longitudinal bars.
As shown in fig. 2 to 5, a first assembling hole 101 with a square cross section is formed at the rear end of the longitudinal rod, a rod body cross section corresponding to the first assembling hole is formed at the tail end of the transverse rod, the tail end of the transverse rod is inserted into the first assembling hole, and when the
The transverse rods and the longitudinal rods are pre-stretched before assembly, framework assembly is carried out after the pre-stretching is finished, and the adjusted framework is based on the tensile stress of the transverse rods and the longitudinal rods, namely the tensile stress is normal and has a corresponding degree of counteracting effect on expansion deformation.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
