Construction tool and method for equipment foundation bolt embedment reserved hole

Abstract

The invention discloses a construction tool and method for an equipment foundation bolt embedment reserved hole. The tool comprises a hole forming tube matched with the reserved hole, and a rebar cage; the rebar cage comprises a plurality of rebar rings arranged in parallel at intervals, a plurality of vertical rebars arranged on the outer sides of the rebar rings, and a cross rebar strip arrangedon the inner side of the bottom rebar ring; the two ends of the hole forming tube are sealed, and the hole forming tube sinks into the rebar cage from the top surface of the rebar cage. The method includes the steps that the position and type of the reserved hole are determined through a drawing, and the tool matched with the reserved hole is manufactured; the rebar cage of the tool is welded tothe reserved hole position of a foundation rebar which is at the same height position as the top surface of the rebar cage, and the hole forming tube is placed in the rebar cage; concrete is poured, the hole forming tube is taken out after initial setting, and the equipment anchor bolt embedment reserved hole is formed. By means of the construction tool and method, the success rate of hole reservation is effectively increased, the reservation construction work of the anchor bolt reserved hole can be economically, quickly and efficiently completed, and the installation quality of equipment is ensured.

Description

technical field [0001] The invention relates to a construction tool and method for laying reserved holes for equipment anchor bolts. Background technique [0002] With the further development of the industrialization process, traditional small workshop factories have been gradually eliminated, and large-scale environmentally friendly industrial enterprises have further flourished. All industrial plants have to be installed with a large number of equipment during construction. Due to equipment installation and equipment The foundation cannot be constructed at the same time, so the holes for the anchor bolts of the equipment must be reserved during the construction of the equipment foundation, and the holes for the anchor bolts of the buried equipment must be fixed by secondary grouting after the equipment is installed. [0003] In order to facilitate the retention of holes during the construction process, holes are usually reserved by means of reserved wooden piles, wooden fo...

Problems solved by technology

[0003] In order to facilitate the retention of holes during the construction process, holes are usually reserved by means of reserved wooden piles, wooden formwork, prefabricated concrete formwork, and preset corrugated pipes; Embedded in the corresponding position, the disadvantage is that the position is not easy to fix, and the hole will collapse when the wooden stake is pulled out; the so-called wooden formwork is used to make the reserved hole, that is, the mandrel with the same size as the reserved hole is made with the template, and the disadvantage is that it is not easy to fix , the mandrel is not easy to take out; the so-called prefabricated concrete formwork, that is, prefabricated prefabricated slabs that are one level higher than the strength of the foundation concrete, has the disadvantage that it is easy to cause grout leakage at the installation joints, and the installation is cumbersome; the so-called prefabricated bellows, that is, prefabricated bellows The disadvantage of indwelling with reserved holes is that it is troublesome to take out and the cost is high
