DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The present invention provides a screw anchor adjustment lock, comprising a locking member 1, wherein an anchor core 2 and an adjusting nut 3 are respectively arranged at both ends of the locking member 1; the locking member 1 is divided into a clamping section 1.1 and a first connecting section 1.2 and a second connecting section 1.3 arranged at both ends of the clamping section 1.1, and the diameter of the second connecting section 1.3 is smaller than the diameter of the clamping section 1.1; the first connecting section 1.2 and the second connecting section 1.3 are both provided with external threads, and the adjusting nut 3 is threadedly connected with the second connecting section 1.3; the locking member 1 is provided with a mounting hole 1.4 along the axial direction, and the mounting hole 1.4 is divided into a tapered hole section 1.41 and a round hole section 1.42, and the round hole section 1.42 is arranged corresponding to the second connecting section 1.3, and the anchor core 2 is adapted to the tapered hole section 1.41 of the mounting hole 1.4;

[0021] The anchor core 2 is a variable anchor core 2, and the anchor core 2 includes an anchor tube 2.1. The anchor tube 2.1 is a frustum structure. The anchor tube 2.1 is composed of three anchor plates 2.11. The anchor tube 2.1 is provided with a fixing ring 2.2 for fixing the three anchor plates 2.11, and the fixing ring 2.2 is a wire ring; a groove 2.12 is provided on the anchor plate 2.11, and the grooves 2.12 on the three anchor plates 2.11 form an annular groove, and the fixing ring 2.2 is located in the annular groove.

[0022] Furthermore, in order to achieve the fixing and limiting effect of the anchor core 2, a connecting tube 4 is threadedly connected to one end of the locking member 1 close to the anchor core 2, and a base 5 is fixedly connected to the end of the connecting tube 4. A through hole 5.1 is opened on the base 5, and the mounting hole 1.4 is in the same straight line as the through hole 5.1.

[0023] Furthermore, in order to improve the connection effect with the connecting rod 6, an anti-slip pattern is provided on the side of the anchor sheet 2.11 away from the clamping groove 2.12; in order to better fix the connecting rod 6 after the anchor core 2 is matched with the mounting hole 1.4, the inner diameter of the small diameter end of the anchor tube 2.1 is made smaller than the inner diameter of the large diameter end of the anchor tube 2.1, and the inner diameter of the large diameter end of the anchor tube 2.1 is the same as the aperture of the through hole 5.1. Therefore, when the anchor core 2 fixes the connecting rod 6, the force of the anchor sheet 2.11 on the connecting rod 6 can be increased, and the connection effect between the anchor core 2 and the connecting rod 6 can be improved by increasing the friction between the connecting rod 6 and the anchor core 2.

[0024] Furthermore, in order to facilitate adjustment when supporting the formwork 9, a clamping platform 1.11 is symmetrically provided at one end of the clamping section 1.1 close to the second connecting section 1.3.

[0025] Furthermore, the base 5 is a regular hexagonal structure.

[0026] The screw anchor adjustment lock provided by the present invention, when in use, after the template 9 is supported, when the template 9 is limited and fixed, the limiting steel plate 7 is first sleeved on the connecting rod 6, and the limiting steel plate 7 is made to contact with the fixing frame 8 on the supported template 9, and then the connecting rod 6 is inserted through the mounting hole 1.4 of the second connecting section 1.3 of the locking member 1, and at the same time, the second connecting section 1.3 is inserted into the through hole 5.1 of the limiting steel plate 7, so that the adjusting nut 3 is in contact with the limiting steel plate 7, and then the anchor core 2 is sleeved on the connecting rod 6, and the anchor core 2 is pushed into the tapered hole section of the mounting hole 1.4. 1.41, then put the connecting tube 4 and the base 5 on the connecting rod 6 in sequence, and make the connecting rod 6 extend from the through hole 5.1 on the base 5, and then connect the connecting tube 4 with the locking member 1 through the first connecting section 1.2. At the same time, the base 5 will generate thrust on the anchor core 2, and further push the anchor core 2 into the tapered hole section 1.41 of the mounting hole 1.4, so that the connecting rod 6 is limited and fixed under the action of the anchor core 2. By adjusting the position of the adjusting nut 3 on the second connecting section 1.3 as needed, the spacing between the two templates 9 can be adjusted, and the operation is simple. The connecting rod 6 can be a steel bar or a carbon fiber rod. The selection of the connecting rod 6 is not limited to the tension bolts with threads at both ends. It is more convenient to obtain materials during construction and save construction costs. After the concrete is poured, only the excess part needs to be cut off, and no holes will be formed, ensuring the pouring quality of the concrete.
