A reusable airbag mold with reserved holes

Abstract

The invention discloses a reusable reserved hole gasbag mould which comprises a positioning body and an expanding body sleeving the positioning body, wherein the two end parts of the expanding body are in sealing connection to the positioning body; the expanding body comprises an elastic gas filling bag; and the positioning body is a cylinder structure which is used for enabling the inner cavity of the elastic gas filling bag to communicate with an outer channel. The reusable reserved hole gasbag mould is novel in structure, is low in cost, is simple to operate, is convenient to dismount, is reusable, saves time and labor, does not generate building waste and solid waste, and meets environment-friendly requirements.

Description

technical field [0001] The invention relates to the technical field of reserved holes for installing anchor bolts of mechanical equipment, in particular to a reusable air bag mold with reserved holes. Background technique [0002] In the process of pouring the concrete foundation of equipment, in order to ensure the accurate positioning of equipment installation, under normal circumstances, most of them adopt the method of pouring concrete twice, that is, before pouring the equipment foundation, pre-fix the reserved hole mold on the laying layer for later installation The anchor bolts of the equipment leave space, and then the concrete is poured, commonly known as one-time pouring. When the equipment is in place, the anchor bolts are installed after initial calibration, and then concrete is poured into the reserved holes, commonly known as secondary pouring. The method of pouring concrete twice is easy to ensure the accuracy of equipment installation, but the problem of conc...

Problems solved by technology

The method of pouring concrete twice is easy to ensure the accuracy of equipment installation, but the problem with concrete pouring twice is that the concrete poured once and twice pours the equipment foundation into several independent solids virtually.

The first two production methods exist: time-consuming, low efficiency, high cost, difficult to remove the formwork (especially the formwork with deep holes or small holes), cannot be reused, and the recycled waste materials form construction waste and pollute the environment What's more, in order to catch up with the construction progress, the bellows are not removed and the concrete is poured directly; at the same time, because the bellows are mostly made of iron sheet materials, they are easy to corrode and rust, resulting in secondary pouring between the concrete with reserved holes and the concrete poured at the first time. gap, when the anchor bolts are under the action of force, there will be a problem that the secondary poured concrete will be partially or entirely pulled out from the hole, which will make the anchor bolts of the equipment invalid and affect the normal operation of the equipment; although the third production method can repeat It is used but the cost is high, the material consumption is large, the efficiency is low, and it is time-consuming and laborious to install and disassemble the model
