Abstract
The utility model discloses an adjustable type opposite-pull screw rod which comprises a first screw rod and a second screw rod. The first screw rod and the second screw rod are oppositely arranged, a fixing member is arranged between the first screw rod and the second screw rod, the first screw rod and the screw rod respectively penetrate through the fixing member, the first screw rod is parallel to the second screw rod, E-type clamps are respectively arranged at two ends of the first crew rod and two ends of the second screw rod, and each of the E-type clamp is connected with the corresponding screw rod in a threaded mode. By the utilization of the adjustable type opposite-pull screw rod, the fixing member is arranged between the first screw rod and the second screw rod, the first screw rod and the second screw rod are clamped and fixed through the E-type clamps, and the E-type clamps at the other end of the first screw rod and the other end of the second screw rod are connected with steel tubes to fix a shear wall framework, the structure is simple, installation is convenient, adaptability is strong, and the length of the opposite-pull screw rod can be adjusted according to the length of a shear wall.
Description
Technical field
The utility model relates to building operations and uses the Screw arbor with nut at both-ends field, is specifically related to a kind of adjustable Screw arbor with nut at both-ends.
Background technology
When shear wall formwork installs, in order to support or fixed form usually needs to use Screw arbor with nut at both-ends, during long the and change in length of shear wall length, bring inconvenience for the setting of Screw arbor with nut at both-ends, the job site is adopted usually and is pressed shear wall length special configuration Screw arbor with nut at both-ends, perhaps Screw arbor with nut at both-ends is cut into two sections, the assembling form of mid-length welded reinforcement optionally again, two kinds of technical schemes are made trouble, and versatility is low, wastes time and energy.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, easy for installation, compliance strong and can be according to the adjustable Screw arbor with nut at both-ends of the length of shear wall length adjustment Screw arbor with nut at both-ends.
For achieving the above object, the utility model provides following technical scheme: a kind of adjustable Screw arbor with nut at both-ends, comprise first screw rod and second screw rod, described first screw rod and second screw rod arrange in opposite directions, be provided with fixture between described first screw rod and second screw rod, and first screw rod and second screw rod pass fixture respectively, described first screw rod and second screw rod are parallel to each other, described first screw rod and the second screw rod two ends are respectively arranged with mountain type card, and described each mountain type card connects with corresponding screw flight.
By adopting technique scheme, between first screw rod and second screw rod, fixture is set, and fasten two screw rods by the mountain type, and fix shear wall formwork by the mountain type card connection steel pipe of the other end, simple in structure, easy for installation, compliance strong and can be according to the length of shear wall length adjustment Screw arbor with nut at both-ends.
The utility model also further is set to: described first screw rod and second screw rod deviate from the fixture end and are respectively arranged with the steel pipe of using Yushan Hill type fastening position.By this setting, structure arranges rationally, and is easy to connect.
The utility model also further is set to: the mountain type card at described first screw rod and the second screw rod two ends is towards being oppositely arranged.By this setting, the utility model work is more reliable.
The utility model also further is set to: described fixture is square tube connector.By this setting, anchor structure arranges rationally, and simple in structure, cost is low.
The utility model has the advantages that: the utility model structure arranges rationally, between first screw rod and second screw rod, fixture is set, and fasten two screw rods by the mountain type, mountain type card connection steel pipe by the other end fixes shear wall formwork, and simple in structure, easy for installation, compliance is strong and can be according to the length of shear wall length adjustment Screw arbor with nut at both-ends.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the disclosed a kind of adjustable Screw arbor with nut at both-ends of the utility model, comprise first screw rod 1 and second screw rod 2, described first screw rod 1 and second screw rod 2 arrange in opposite directions, be provided with fixture 3 between described first screw rod 1 and second screw rod 2, and first screw rod 1 and second screw rod 2 pass fixture 3 respectively or are threaded with fixture 3, described first screw rod 1 and second screw rod 2 are parallel to each other, described first screw rod 1 and second screw rod, 2 two ends are respectively arranged with mountain type card 4, and described each mountain type card 4 connects with corresponding screw flight.When the shear wall change in length, can finish the variation of Screw arbor with nut at both-ends length by rotating first screw rod 1 or second screw rod 2.
Described first screw rod 1 and second screw rod 2 deviate from the fixture end and are respectively arranged with the steel pipe 5 of locating with Yushan Hill type card 4.
For making the utility model work more reliable, as preferably, the mountain type card 4 at described first screw rod 1 of present embodiment and second screw rod, 2 two ends is towards being oppositely arranged, and described fixture 3 is square tube connector.
During practical application, first screw rod 1 and first screw rod 2 pass tube connector 3 in opposite directions, and fixing with mountain type card 4, and first screw rod 1 and first screw rod 2 are all fixed with two steel pipes 5 with respect to the other end of tube connector 3, finish the reinforcing of shear wall formwork.Simple in structure, easy for installation, compliance is strong and can be according to the length of shear wall length adjustment Screw arbor with nut at both-ends.
Above-described embodiment is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician of this area makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned utility model and all falls within the protection domain of the present utility model.
