Embedded bolt cleading

Abstract

The invention discloses an embedded bolt cleading which comprises a steel plate, galvanized pipes and two connecting steel pipes, wherein 2 to 10 positioning holes are drilled on the steel plate, a cross axis is carved on the steel plate, and the steel plate is also provided with a vibrating hole the center of which is positioned at the crossing point of the axis; the galvanized pipes are fixed on the upper end surface of the steel plate by welding, the axes of the galvanized pipes are vertical to the upper end face of the steel plate, each galvanized pipe is positioned at one positioning hole of the steel plate correspondingly, the inner diameter of the galvanized pipe is equal to the diameter of the positioning hole, and the axis of the galvanized pipe and the axis of the positioning hole are the same; and the two connecting steel pipes are respectively welded outside the galvanized pipes. The galvanized pipes are welded at the positioning holes, therefore, the embedded bolt cleading can well limit the position of a bolt. The connecting steel pipes enable the cleading to be convenient to install and dismantle.

Description

technical field [0001] The invention relates to a construction device, in particular to a pre-embedded bolt sleeve plate used for bolt positioning in the construction of pre-embedded bolts at the bottom of a column. Background technique [0002] With the development of the construction industry to the present, steel structure buildings have risen rapidly due to their advantages such as low cost and good seismic performance. The steel columns of steel structure buildings are generally rooted on the foundation concrete column base through pre-embedded anchor bolts, but it is difficult to accurately locate the pre-embedded bolts during the installation process, and the bolts are likely to be displaced during the pouring of the foundation concrete, which will affect the Detrimental effect on subsequent superstructure installation. Therefore, the firmness and installation accuracy of the pre-embedded installation of foundation anchor bolts are important factors affecting the ins...

Problems solved by technology

However, when this kind of formwork is used, the bolts can only be positioned and supported by the positioning holes. Usually, the embedded bolts are relatively long. Loosening will affect the precise positioning of the bolts and affect the quality of the building

And there is also defect in the placement of this formwork during use, because this formwork does not have the structure that can make formwork be placed on the post wood formwork of steel column, so this formwork area must be greater than the steel column surface area to be poured, on the one hand inconvenient Pouring concrete, on the other hand, when the embedded bolts are designed in the middle of large steel columns, then the production of formwork will waste raw materials
