Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a building core tube shear wall. Background Art

[0002] The core tube is the central part of the building, which is surrounded by elevator shafts, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms to form a central core tube, and the outer frame forms an outer frame inner tube structure, which is poured with reinforced concrete. The patent document with application publication number CN 118241855A discloses a template support reinforcement structure at the corner of the shear wall of the building core tube. The structure reinforces the Yin and Yang corner templates by adding Yin and Yang corner templates on the basis of the existing steel pipe and fastener support reinforcement structure. The right-angle shaper and the template shaping plate are used to hold the Yang corner template, and then the friction of the anti-deflection seat is used to effectively prevent the movement of the Yang corner template during the pouring process. The state of the template is monitored by detecting the distance between two micro ultrasonic ranging sensors 1 and 2 and the reflector. When the template deflects and moves, an alarm can be triggered to remind workers to correct the template in time, thereby ensuring the squareness of the Yin and Yang corners and effectively improving the molding quality.

[0003] In the above patent document, the friction of the anti-deviation seat is used to effectively prevent the external corner template from moving during the pouring process. However, compared with the area of ​​the external corner template, the contact area between the anti-deviation seat and the external corner cross plate is small, making it difficult to achieve the effect of preventing the external corner template from moving during the pouring process. The use of micro ultrasonic ranging sensors has high requirements for the design of the support reinforcement structure. Utility Model Content

[0004] The technical problem solved by the utility model is that at the corner of the shear wall of the building core tube, it is difficult to achieve the effect of preventing the external corner template from moving during the pouring process by using the friction between the anti-deviation seat and the external corner template.
