Description

Paying-off hole die

Technical Field

The utility model relates to a paying-off hole die, which is particularly used for measuring paying-off of civil engineering.

Background

Currently, in the building construction process, each layer needs to be precisely positioned on the axis, and the axis of the next layer is usually projected to the previous layer. The axis of the next layer is projected to the previous layer by a plumb line through a plurality of paying-off holes. A residential building with a simple structure may need to be provided with 4 pay-off holes, a residential building may need to be provided with hundreds of pay-off holes, and a building engineering project may need to be provided with hundreds of pay-off holes. The existing paying-off hole is reserved in a square box which is generally processed by a bamboo plywood, time and labor are wasted during working, demolding is not easy, recycling is not easy, waste is caused, more importantly, reserved holes reserved in the square die are easy to fall off after later pouring, and major potential safety hazards exist. On the other hand, the pay-off hole is required to be plugged after being used, and the pay-off hole of the square box is different in size, so that a unified plugging block is not suitable for being manufactured to plug the pay-off hole in the later period, and a template is required to be built again at the pay-off hole to pour concrete for plugging, so that manpower and material resources are wasted, and the construction period is prolonged.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide the paying-off hole die, so as to solve the defects of difficult demolding, easy falling, poor recycling rate and the like of the existing paying-off hole die, and the paying-off hole can be rapidly plugged in the later stage, thereby improving the efficiency, quality and safety of the construction of the reserved paying-off hole.

The basic conception of the technical scheme adopted by the utility model is as follows: the utility model provides a unwrapping wire hole mould for set up and then form unwrapping wire hole on every layer of concrete floor, unwrapping wire hole mould is including being the mould body of back taper platform shape, and this mould body divide into two symmetrical lamella, and wherein 1 two lamella adjacencies are connected with two hinges, and 1 two other lamella adjacencies are connected through the buckle, hinge and buckle all install in mould body inner wall, the mould body includes upper shed and lower shed, upper shed's opening is greater than the lower shed, the lower shed is used for passing concrete floor.

Preferably, the upper opening is provided with a lifting handle.

Preferably, the upper opening and the lower opening are circular, the diameter of the upper opening is 200mm, the diameter of the lower opening is 160mm, and the distance between the upper opening and the lower opening is 200mm.

The beneficial effects of the utility model are as follows: when the beam slab template is used, holes are formed in the paying-off holes after the beam slab template is installed, paying-off hole dies are installed after slab reinforcement is bound, and the dies are removed after the concrete strength reaches the requirement after concrete pouring is completed. According to the utility model, the paying-off hole mould is adopted to manufacture the paying-off hole with good forming effect and consistent size on the concrete floor slab, so that the accurate manufacturing of the paying-off hole is realized, and the measurement requirement is met. After the pay-off hole is used, the plugging block uniformly manufactured by the pay-off hole die can be used for quick plugging, so that the aim of efficient construction is fulfilled. Compared with the prior art, the utility model has the advantages of simple structure, convenient construction, convenient assembly and disassembly, time and labor saving in use, improved working efficiency, accelerated engineering progress, material saving and the like.

Drawings

The utility model is described in further detail below with reference to the attached drawing figures, wherein:

FIG. 1 is a schematic diagram of a pay-off hole die;

FIG. 2 is a rear view of FIG. 1;

FIG. 3 is an outline view of a pay-off hole die;

FIG. 4 is a schematic view of the buckle in FIG. 2;

in the figure, a 1-die body I, a 2-die body II, a 3-hinge I, a 4-hinge II, a 5-buckle, a 6-lifting handle, a 7-upper opening, an 8-lower opening, a 9-base, a 10-fixing bolt, an 11-connecting rod and a 12-clamping groove are formed.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the mold body I1 and the mold body II 2 are symmetrical two pieces, wherein 1 two piece adjacent positions are connected by a hinge I3 and a hinge II 4, and the other 1 two piece adjacent positions are connected by a buckle 5, wherein the hinge I3, the hinge II 4 and the buckle 5 are all installed on the inner walls of the mold body I1 and the mold body II 2, and the buckle 5 is composed of a base 9, a fixing bolt 10, a connecting rod 11 and a clamping groove 12. The die body I1 and the die body II 2 are folded, the paying-off hole die is in an inverted cone shape, the connecting rod 11 is placed in the clamping groove 12, the paying-off hole die is locked, the connecting rod 11 is taken out of the clamping groove 12, and the paying-off hole die can be opened. The upper opening 7 and the lower opening 8 are both circular, the diameter of the upper opening 7 is 200mm, the diameter of the lower opening 8 is 160mm, the distance between the upper opening 7 and the lower opening 8 is 200mm, and the lower opening 8 is used for penetrating through the concrete floor. The upper opening 7 is provided with a lifting handle 6, and the lifting handle 6 is grasped to pull out the paying-off hole die Shi Yongshou after the paying-off hole die is detached.
