Shaft masonry mold

Technical Field

The utility model belongs to the technical field of municipal engineering, and particularly relates to a shaft masonry mold.

Background

At present, most of the well bores are built by workers through experience, the well bores are easy to build out of round, the thickness of each layer of mortar cannot be guaranteed in the building process, the problem that the building height of the same layer is uneven can occur, in the building process, as no reference object exists, the circle center of the well bore cannot be measured and determined along with the increasing height of the well bore, and the problems that the finally built well bore deviates and the height of the well bore is high are easily caused.

In order to solve the above problems, some molds for shaft construction are disclosed, for example ZL2016211922712, and patent entitled "cylindrical well construction mold", which discloses a mold for controlling shaft construction, but the mold in this patent cannot be taken layer by layer, so that a plurality of layers of molds must be arranged from the bottom of the shaft, the height of the final plurality of layers of molds is equal to that of the shaft, the molds can be extracted after the shaft construction is completed, and the later extraction of the molds is difficult, and the completion of shaft construction and re-extraction of the molds can cause problems of loosening bricks, deformation of the shape of the whole shaft, difficulty in extracting the molds, and the like.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model.

The mold comprises a cylinder 1, wherein the outer diameter of the cylinder 1 is equal to the inner diameter of a shaft to be built, an inner support 2 is arranged inside the cylinder 1, the inner support 2 is used for supporting the cylinder 1 and preventing the cylinder 1 from deforming in the using process, the inner support 2 can be convenient for moving the cylinder 1 in the using process, a worker holds the inner support 2 by hand, and therefore lifting and moving of the cylinder 1 can be achieved without additionally arranging a separate lifting structure. The inner support 2 selected in this embodiment is a cross support, as shown in fig. 2, and the end of the cross support is welded on the inner surface of the cylinder 1. The upper surface of the inner support 2 is also provided with a level meter 5, the level meter 5 is a bubble level meter, and the level meter 5 is used for guaranteeing the horizontality of the die, thereby guaranteeing the horizontality of each layer of masonry.

A plurality of calibration sheets 3 are uniformly fixed outwards in a circle on the outer surface of the vertical cylinder 1, the calibration sheets 3 are vertical thin iron sheets and are welded on the cylinder 1, preferably, the calibration sheets 3 are uniformly provided with four sheets, the length of each calibration sheet 3 is 5cm, the thickness of each calibration sheet is 1mm, the height of each calibration sheet 3 is equal to the thickness of a mortar layer to be smeared, the distance between the upper surface of each calibration sheet 3 and the upper surface of the cylinder 1 is equal to the thickness of a brick 4, and the distance between the lower surface of each calibration sheet 3 and the lower surface of the cylinder 1 is also equal to the thickness of the brick 4.
