Description
Technical Field
The utility model relates to a steel strand wires construction technical field, concretely relates to ware is prevented opening by prestressing force steel strand wires.
Background
In recent years, the investment of the country on infrastructure construction is increased year by year, more and more projects using prestressed steel strands are used for prefabricating and cast-in-place box girder bridges, suspension bridges, cable-stayed bridges and the like, the construction of the steel strands is increasingly emphasized, the prestressed steel strands are often wound into a coil shape for facilitating the transportation of the prestressed steel strands, but the stress generated by the coiled coil is larger due to the larger strength and toughness of the steel strands.
Therefore, in the use, must be with the stress release of disc prestressing force steel strand coils, otherwise the steel strand wires easily bullet wound the people when opening the dish for in the work progress, great injury accident will appear if handling the improper stress release of steel strand wires circle, and current prestressing force steel strand wires are mostly the integral type device, difficult dismouting, and the installation is transported inconveniently, influences the efficiency of construction.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a ware is prevented opening by prestressed steel strand wires to solve current prestressed steel strand wires and prevent opening ware and be difficult for dismouting, installation transportation inconvenient, influence the technical problem of efficiency of construction.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a ware is prevented opening by prestressing force steel strand, first unit frame and the second unit frame that sets up around including, it can freely dismantle four support steel pipes to fix being provided with between first unit frame and the second unit frame, first unit frame, second unit frame and support form a fixed cavity between the steel pipe for prestressing force steel strand's coil is fixed in fixed cavity. Still fixedly on the support body in the first unit frame outside be provided with and prevent a ring for prestressing force steel strand wires follow prevent drawing out in the ring, also released simultaneously because the dish produced huge prestressing force together, avoided the emergence that the prestressing force hurt people's condition.
Preferably, the first unit frame and the second unit frame are formed by welding and fixing four unit steel pipes with the same length in an encircling manner from head to tail.
Preferably, first unit frame and second unit frame are all through cross buckle and support steel pipe fixed connection, when not using, can dismantle the cross buckle for prestressing force steel strand wires prevents a ware and falls into the triplex, conveniently carries transportation and simple to operate.
Preferably, the tension-proof ring is welded and fixed on the frame body outside the first unit frame through four steel bars, and the welding and fixing structure is high in rigidity, good in integrity and not easy to deform.
Preferably, the tension preventing ring is made of stainless steel metal materials, is not easy to deform and rust and has long service life.
Compared with the prior art, the utility model discloses a main beneficial technological effect includes:
first unit frame, second unit frame and setting are the cross buckle between them and can dismantle the connection, make things convenient for the dismouting and transport, improve the efficiency of construction, prevent opening the circle and make for stainless steel metal material, non-deformable rusts, long service life.
The whole device is formed by welding and processing the most common steel pipe reinforcements on the construction site, is convenient to process and has low cost.

Fig. 1 is the utility model discloses a structure schematic diagram is looked to prestressing force steel strand wires stretching preventer's owner.
Fig. 2 is the utility model discloses a structure schematic diagram is looked to a left side of prestressing force steel strand wires ware of preventing stretching.
In the above figures, 1 is the first unit frame, 2 is the second unit frame, 3 is the unit steel pipe, 4 is the support steel pipe, 5 is the cross fastener, 6 is the stretch-proof circle, 7 is the reinforcing bar.
Detailed Description
The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.
The components and parts in the following examples are all conventional commercially available products unless otherwise specified.
Example 1: the utility model provides a prestressing force steel strand stretching preventer, refers to fig. 1 and fig. 2, includes first unit frame 1 and the second unit frame 2 that sets up around, fixedly between first unit frame 1 and the second unit frame 2 being provided with four detachable support steel pipes 4, form a fixed cavity between first unit frame 1, second unit frame 2 and the support steel pipe 4 for prestressing force steel strand's coil is fixed in fixed cavity. Still fixedly on the support body in the first unit frame 1 outside be provided with and prevent a ring 6 for prestressing force steel strand wires follow prevent in the ring 6 being pull out, released simultaneously because the dish is together produced huge prestressing force.
Further, the first unit frame 1 and the second unit frame 2 are formed by welding and fixing four unit steel pipes 3 with the same length in an end-to-end surrounding mode, the bottom of one unit steel pipe 3 is welded to the side face of the other unit steel pipe, the unit steel pipes are sequentially welded in a circulating mode to form an integral structure, and the four unit steel pipes 3 are perpendicular to each other. First unit frame 1 and second unit frame 2 all through cross buckle 5 with support 4 fixed connection of steel pipe, cross buckle 5 includes two bolts, when not using, can dismantle cross buckle 5 for prestressing force steel strand wires prevents a ware and falls into the triplex, conveniently carries transportation and simple to operate. The tension-proof ring 6 is welded and fixed on the frame body outside the first unit frame 1 through four steel bars 7, and the welding and fixing structure is high in rigidity, good in integrity and not easy to deform. The tension-proof ring 6 is made of stainless steel metal materials, is not easy to deform and rust and has long service life.
The working principle and the installation and use method of the prestressed steel strand tension preventer are as follows:
during installation, the first unit frame 1 and the second unit frame 2 are prevented from being arranged on two sides of a coil formed by pre-stressed steel strands, then a support steel pipe 4 is installed between the first unit frame 1 and the second unit frame 2, and after the support steel pipe is fixed by a cross buckle 5, the installation is completed; when the anti-stretching ring is used, the steel strand can be stretched outwards through the anti-stretching ring 6 and is pulled, and the shape of the anti-stretching ring 6 can limit the moving range of the steel strand, so that the prestress is relieved; after the use, demolish the bolt on the cross buckle 5 and can prevent a ware with the prestressing force steel strand wires and divide into the triplex, conveniently carry the transportation, the installation is easy, does not influence the efficiency of construction.
The present invention has been described in detail with reference to the accompanying drawings and embodiments, but those skilled in the art will understand that various specific parameters in the above embodiments can be changed without departing from the spirit of the present invention to form a plurality of specific embodiments, which are the common variation ranges of the present invention and will not be described in detail herein.
