Description

Fixing device for arc wall Technical Field The utility model belongs to the technical field of constructional engineering, and particularly relates to a fixing device for an arc wall. Background In arc wall construction, traditional supporting mode has the problem that the regulation precision is low, stability is poor. In the prior art, a simple diagonal bracing structure is adopted, so that accurate perpendicularity control cannot be realized, the template is easy to deform, and the concrete forming quality is difficult to guarantee. Especially in complex curved surface construction, the conventional support system is difficult to adapt to the change of different curvatures, and the adjustment process is time-consuming and labor-consuming. Although some adjustable supporting devices exist, the adjustable supporting device still has the defects of limited adjusting range, easy looseness of nodes and the like, and cannot meet the high-standard construction requirements. These deficiencies affect the efficiency of construction and quality control of the arcuate wall. Disclosure of utility model The utility model provides a fixing device for an arc wall body, which is used for solving the problem that the verticality of the arc wall body in the prior art cannot be controlled. The utility model provides a fixing device of an arc wall, which comprises a pre-embedded anchor bolt, an adjusting screw and at least two supporting units, wherein the pre-embedded anchor bolt is arranged on the arc wall; the embedded anchor bolt is arranged in the structural plate and positioned at the center of the arc wall, the top of the embedded anchor bolt is fixedly connected with an adjusting screw, and at least two supporting units are sleeved on the adjusting screw; The supporting unit comprises a fastening sleeve, an upper inclined strut and a lower inclined strut, wherein the inner wall of the fastening sleeve is provided with threads matched with the adjusting screw, the outer profile of the fastening sleeve is of a quadrilateral section, the fixed ends of the upper inclined strut and the lower inclined strut are respectively connected with the outer side wall of the fastening sleeve, the supporting ends of the upper inclined strut and the lower inclined strut can be adjusted in the vertical direction, and the supporting ends are connected with U-shaped clamping plates and are used for being clamped with a main keel of an arc wall body. Compared with the prior art, the utility model has the advantages that the force systems of all diagonal braces are converged at the geometric center of the arc wall body through the embedded anchor bolts positioned at the circle centers to form a stable supporting system, and the coordination of the fastening sleeve with the quadrangular cross section and the screw rod provides four standardized installation planes for diagonal brace connection, so that the universal adjustment of the diagonal braces is ensured, and the installation is simple. Further, a pair of ear plates are fixedly connected to at least one outer side wall of the fastening sleeve, the ear plates are provided with a plurality of vertically arranged adjusting holes, and fixed ends of the upper inclined strut and the lower inclined strut are hinged through adjusting hole assembly pins of the ear plates respectively.
