Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the three-section type split bolt disclosed in this embodiment includes an adjusting screw 1 located in the middle and fixing screws 2 located at two ends of the adjusting screw 1, where the fixing screws 2 are parallel to the adjusting screw 1. Adjusting screw 1 is two-way threaded rod, and the equal thread bush in both ends of adjusting screw 1 is equipped with adjusts seat 3, adjusts the setting of seat 3 perpendicular to adjusting screw 1, and the one end that two clamping screw 2 are close to each other is fixed respectively in the center department that two were adjusted seat 3. The adjusting seat 3 is cuboid, one side surface is a plane, and the side surface opposite to the plane is concave towards the plane to form two semi-circular concave cambered surfaces. A plurality of friction grooves 9 have all been seted up in plane and the cambered surface, and friction groove 9 makes the surface unevenness of adjusting seat 3, has increased the coefficient of friction on surface.

The two adjusting seats 3 are respectively sleeved on opposite threads at two ends of the adjusting screw rod 1 in a threaded manner, and the two ends of the adjusting screw rod 1 are respectively fixed with a limiting block 8 for limiting the sleeved positions of the adjusting seats 3 on the peripheral side of the adjusting screw rod 1. The center of adjusting screw 1 is fixed with operation panel 7 on week side, and operation panel 7 is convenient for the workman to operate adjusting screw 1 and rotates, makes two regulation seats 3 drive two fixing screw 2 and is close to each other or keep away from each other, realizes shortening or the extension of distance.

The fixing seat 4 is sleeved at one end, away from each other, of each of the two fixing screw rods 2, the fixing screw rods 2 penetrate through the center of the corresponding fixing seat 4, the corresponding fixing seat 4 is cuboid, one side face of the corresponding fixing seat is a plane, and the side face opposite to the plane is concave towards the plane to form two semicircular concave arc faces. A plurality of friction grooves 9 have been all seted up in plane and the cambered surface, and friction groove 9 makes the surface irregularity of fixing base 4, has increased the coefficient of friction on surface.

One side of two fixing bases 4 that keep away from each other all supports and has the screw thread cover to establish the fixation nut 5 at fixing bolt week side. After the adjusting screw rod 1 and the fixing screw rod 2 are fixed in position, the two fixing seats 4 are close to each other by adjusting the fixing nuts 5, and the constructed formwork is clamped and positioned, so that the concrete is poured and formed conveniently.

Wear to be equipped with connecting rod 6 between two fixing bases 4, connecting rod 6 passes two simultaneously and adjusts seat 3, is connected fixing base 4 and regulation seat 3 through connecting rod 6, is convenient for adjust seat 3 and adjusting screw 1's guiding orientation, in the work progress, can keep the level to press from both sides tightly, reduces crooked. Connecting rod 6 and adjusting screw 1 are located fixing screw 2's both sides respectively and about fixing screw 2 symmetry, and this makes whole syllogic split bolt's atress more even, and the atress intensity is better.

The implementation principle and the beneficial effects of the embodiment are as follows:

firstly, a worker operates the adjusting screw rod 1 to rotate, so that the two adjusting seats 3 drive the two fixing screw rods 2 to be close to each other, and the length of the three-section type split bolt is reduced. And then the three-section type split bolt is arranged in a constructed template, the fixing screw rods 2 at two ends respectively penetrate through two ends of the template, two ends of the connecting rod 6 also penetrate out, and the three-section type split bolt is perpendicular to the plate wall of the template when the position of the connecting rod 6 is controlled. Then, the fixing seat 4 is sleeved on the end part of the fixing screw rod 2 penetrating out of the template, and finally, the fixing seat 4 can be tightly abutted on the side wall of the template through the rotation of the fixing nut 5 and the adjusting screw rod 1.

The utility model discloses an adjusting screw 1 drives two adjustment discs simultaneously and adjusts, only needs to adjust two fixing bases 4 and fixation nut 5's butt in the operation process, and last cooperation adjusting screw 1 rotates and adjusts, and whole operating procedure significantly reduces, and the fault-tolerant rate improves, and is more laborsaving convenient.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
