Abstract
The invention discloses an adjustable split screw which comprises a first screw and a second screw. The first screw and the second screw are arranged in opposite direction, a fixing part is arranged between the first screw and the second screw, the first screw and the second screw respectively penetrate through the fixing part, the first screw and the second screw are parallel to each other, clamps shaped like a Chinese character 'shan' are respectively arranged at two ends of the first screw and the second screw, and each clamp shaped like the Chinese character 'shan' is connected with the corresponding screw in a threaded mode. Due to the fact that the fixing part is arranged between the first screw and the second screw, the two screws are fixed through the clamps shaped like the Chinese character 'shan', and the other end of each screw is connected with a steel pipe through the clamps shaped like the Chinese character 'shan' at the other end so as to fix shear wall formworks. The adjustable split screw has the advantages of being simple in structure, convenient to install, good in adaptability and capable of adjusting the length of the split screw according to the length of shear walls.
Description
Technical field
The present invention relates to building operations and use the Screw arbor with nut at both-ends field, be 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 usually adopted 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
For the deficiency that prior art exists, the object of the present invention is to provide a kind of simple in structure, easy for installation, strong adaptability 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 invention provides following technical scheme: a kind of adjustable Screw arbor with nut at both-ends, comprise the first screw rod and the second screw rod, described the first screw rod and the second screw rod arrange in opposite directions, be provided with fixture between described the first screw rod and the second screw rod, and the first screw rod and the second screw rod pass respectively fixture, described the first screw rod and the second screw rod are parallel to each other, described the 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 the first screw rod and the second screw rod, fixture is set, and fasten two screw rods by the mountain type, and the mountain type by the other end links and connects steel pipe and fix shear wall formwork, simple in structure, easy for installation, strong adaptability and can be according to the length of shear wall length adjustment Screw arbor with nut at both-ends.
The present invention also further is set to: described the first screw rod and the second screw rod deviate from the fixture end and are respectively arranged with the steel pipe of using Yushan Hill type engaging position.By this setting, structure arranges rationally, and is easy to connect.
The present invention also further is set to: the mountain type card at described the first screw rod and the second screw rod two ends is towards being oppositely arranged.By this setting, work of the present invention is more reliable.
The present invention 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.
Advantage of the present invention is: structure of the present invention arranges rationally, between the first screw rod and the second screw rod, fixture is set, and fasten two screw rods by the mountain type, mountain type by the other end links and connects steel pipe and fix shear wall formwork, simple in structure, easy for installation, strong adaptability and can be according to the length of shear wall length adjustment Screw arbor with nut at both-ends.
The invention will be further described below in conjunction with specification drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of adjustable Screw arbor with nut at both-ends disclosed by the invention, comprise the first screw rod 1 and the second screw rod 2, described the first screw rod 1 and the second screw rod 2 arrange in opposite directions, be provided with fixture 3 between described the first screw rod 1 and the second screw rod 2, and the first screw rod 1 and the second screw rod 2 pass respectively fixture 3 or are threaded with fixture 3, described the first screw rod 1 and the second screw rod 2 are parallel to each other, described the first screw rod 1 and the 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 complete by rotating the first screw rod 1 or the second screw rod 2 variation of Screw arbor with nut at both-ends length.
Described the first screw rod 1 and the 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 work of the present invention more reliable, as preferably, the mountain type card 4 at described the first screw rod 1 of the present embodiment and the second screw rod 2 two ends is towards being oppositely arranged, and described fixture 3 is square tube connector.
During practical application, the first screw rod 1 and the first screw rod 2 pass tube connector 3 in opposite directions, and fixing with mountain type card 4, and the first screw rod 1 and the first screw rod 2 are all fixing with two steel pipes 5 with respect to the other end of tube connector 3, complete the reinforcing of shear wall formwork.Simple in structure, easy for installation, strong adaptability 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 invention; only be used for the present invention is further illustrated; can not be interpreted as the restriction to protection domain of the present invention, the technician of this area according to the content of foregoing invention, the present invention is made some nonessential improvement and adjust all fall into protection scope of the present invention within.
