Abstract
The utility model relates to a kind of stretching construction device in architectural engineering more particularly to a kind of tensioning fixtures.The string end setting of a kind of tensioning fixture, including two semicircular casting, the casting is fluted, and the groove of two casting connects into the shape to match with tube, and an annular construction member is provided in the cambered surface of the casting.The square that two groove of tensioning fixture is spliced into, the objects such as tubulose can sufficiently be fixed, the pipe fitting object fixed for rotation fixture provides impetus, pass through annular construction member, chain block can be made full use of to rotate, it is rotated compared to traditional using Chain wrench, largely saves manpower, and rotating effect is good.
Description
Technical field
The utility model relates to a kind of stretching construction device in architectural engineering more particularly to a kind of tensioning fixtures.
Background technique
Chain-type wrench, also referred to as chain wrench, it includes clamp handle and one end and the hinged chain of clamp handle, the front end of clamp handle be equipped with
The tooth of chain engagement, chain is hinged by joint cover and clamp handle, i.e. one end of chain and one end of joint cover is hinged, joint cover
The other end is hinged with clamp handle.The tooth of the front end of clamp handle is distributed in circular arc.The chain type pipe tongs at work, the non-articulated end of chain
Be it is free, do not fixed with clamp handle or hingedly, clamping, the rotation of pipe fitting are by the frictional force between pipe fitting and the chain for winding it
Come what is realized, and torsion is generated by the local gear wheel of clamp handle front end and the engagement force of chain, and clamp handle does not have in tube surface
Exert a force position.Chain-type wrench when in use, is controlled, malfunction, in use using manpower control clamp handle
It is easy to wear, cause manpower and material resources cost of investment larger.
Summary of the invention
The utility model aim is in view of the deficiencies of the prior art, to provide a kind of tensioning fixture.
A kind of tensioning fixture, including two semicircular casting, the string end of the casting is provided with a groove, described in two
The groove of casting is spliced into the shape to match with drag-line section；An annular structure is provided in the cambered surface of the casting
Part.
The groove is set as rectangle, and the base length of groove is 2 times of depth of groove, and the groove of two casting connects
It is connected into a square.
Two casting are bolted.
The both ends of the casting are provided with symmetrical lug, and bolt hole is equipped on lug, and bolt passes through bolt hole and spiral shell
Female spiral connection.
The width of the lug is less than the depth of the groove.
The annular construction member is regular hexagon.
The casting is ironware.
The utility model has the advantages that the square that two groove of (1) tensioning fixture is spliced into, can sufficiently fix tubular articles, for rotation
The tubular articles that fixture is fixed provide impetus；(2) by annular construction member, chain block can be made full use of to rotate, phase
It is rotated than traditional using Chain wrench, largely saves manpower, and rotating effect is good；(3) tensioning fixture simple shape
It is firm larger with the contact surface for the tubular articles fixed, it compares and Chain wrench, loss is small, and service life is long, practical cost
It is low；(4) tensioning fixture volume weight is small, using flexible easy for installation.
Detailed description of the invention
Fig. 1 be the utility model structure diagram.
In figure, 1, casting；2, lug；3, groove；4, bolt hole；5, annular construction member.
Specific embodiment
Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model
It is not limited to the embodiment.
A kind of tensioning fixture, including two semicircular casting 1, the string end setting fluted 3 of the casting 1, the casting
An annular construction member 5 is provided in the cambered surface of part 1.
The groove 3 is set as rectangle, and the base length of groove 3 is 2 times of 3 depth of groove, two casting 1 it is recessed
Slot 3 connects into a square.
Two casting 1 are bolted.
The both ends of the casting 1 are provided with symmetrical lug 2, and bolt hole 4 is equipped on lug 2, and bolt passes through bolt hole 4
It is connect with nut screw.
The width of the lug 2 is less than the depth of the groove 3.
The annular construction member 5 is regular hexagon.
The casting 1 is ironware.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
