Horizontal construction joint reinforcing bolt and reinforcing method based on bolt
A technology of horizontal construction joints and bolts, which is applied to the joints of formwork/formwork/work frame, formwork/formwork/work frame, and on-site preparation of building components. The system lacks problems such as the connection of the old wall structure to achieve the effect of reducing construction slag, ensuring the smoothness of the wall surface, and good quality of one-time molding

Example Embodiment
[0040] Example 1:
[0041] Such as Figure 1 to Figure 3 A horizontal construction joint reinforcement bolt shown includes an inner wall screw 1, and both ends of the inner wall screw 1 are threadedly connected with the outer wall screw 2 and the connecting wall fixing member 3; the outer wall screw 2 includes a base part 21, a base part 22, and a screw part 23 connected in sequence. The outer diameter of the base part 21 is larger than the outer diameter of the base part 22. The base part 21 is provided with a threaded hole 24, and the base part 22 is provided The threaded groove 25 communicated with the threaded hole 24, the threaded hole 24 and the threaded groove 25 are coaxial with the screw portion 23, and the threaded hole 24 and the threaded groove 25 are matched with the inner wall screw 1; A tapered sleeve 4 is sleeved on the screw 1 in the inner wall section, and the tapered sleeve 4 is coaxial with the screw 1 in the inner wall section. The groove 26 matched with the...

[0042] Example 2:
[0043] Such as Figure 1 to Figure 3 A horizontal construction joint reinforcement bolt is shown. On the basis of Embodiment 1, the connecting wall fixing member 3 includes a bottom plate 31, a protrusion 32 fixed on the bottom plate 31, and the protrusion 32 is arranged in the wall. The threaded insertion hole that matches the segment screw 1, and the inner-wall segment screw 1 is inserted into the threaded insertion hole; the screw 5 is fixedly connected to the bottom plate 31, and the screw 5 extends from the bottom plate 31 away from the side where the protrusion 32 is located. Out. The groove 26 is tapered with a diameter gradually decreasing from the open end to the bottom end, and the bottom end of the groove 26 matches the base part 21; when the base part 21 is located at the bottom end of the groove 26, The base portion 21 and the base portion 22 are both located in the groove 26. A mountain-shaped pipe clamp 6 is movably sleeved on the outer screw ...
