Abstract

The invention discloses a variable-diameter building hole reservation device, and relates to the technical field of buildings. The variable-diameter building hole reservation device comprises a mounting base, wherein the inner wall of the mounting base is fixedly connected to springs I which are uniformly distributed; the outer sides of the springs I are fixedly connected to top blocks; the outersides of the top blocks are fixedly connected to a telescopic plate I and a telescopic plate II; rubber sleeves sleeve outside the telescopic plate I and the telescopic plate II; and the middle partsof rubber sleeves are filled with electrorheological fluid. According to the variable-diameter building hole reservation device disclosed by the invention, rotary plates are matched with the top blocks for use, so that the rotary plates are rotated to realize extension and retraction of the top blocks in use, and therefore, size of the diameter of the hole reservation device is changed, and hole reservation needs are met; and moreover, blocking blocks and blocking slots are used for realizing diameter fixing of the reservation device, so that later-stage pouring is convenient, and therefore, the variable-diameter effect is achieved, practicability is effectively improved, later-stage recycling and classifying of the reservation device is convenient, and labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a variable-diameter construction hole reservation device. Background technique [0002] During the construction process, it is often encountered that holes are reserved, which is convenient for later pipeline laying and decoration. Most of the holes are reserved before concrete pouring. A cylinder with the same diameter as the hole is placed in the reserved hole position. When pouring concrete, reserved holes can be formed automatically. [0003] The current reserved hole construction is relatively simple, and the demand for the cylinder is also relatively large, because the diameter of the reserved hole is different, while the diameter of the cylinder is fixed and cannot be changed, resulting in low practicability of the cylinder, and each The diameter of the cylinder needs to be prepared in multiple groups, and the quantity is large, which is not convenient for later recy...
