Positioning device for anchor bolts and construction method of positioning device

Abstract

The invention discloses a positioning device for anchor bolts. The positioning device comprises a pile body index dial. The outer wall of the pile body index dial is uniformly and circumferentially connected with telescopic tubes perpendicular to the surface of the outer wall of the pile body index dial at intervals. Device positioning blocks are fixed to the ends of the telescopic tubes. Device positioning bolts are arranged in the device positioning blocks correspondingly. A plurality of sets of first clamping strips capable of moving left and right are connected between the surfaces of the opposite inner walls of the front side and the rear side of the pile body index dial. Every two opposite semicircular grooves located in the two first clamping strips of the same set form a positioning groove matched with a thread on one anchor bolt. A plurality of sets of second clamping strips capable of moving front and back are connected between the surfaces of the opposite inner walls of the left side and the right side of the pile body index dial. Every two opposite semicircular grooves located in the two second clamping strips of the same set form a positioning groove matched with a thread on one anchor bolt. A gap exists between the first clamping strips and the second clamping strips in the longitudinal direction. The positioning device is simple in structure, easy to machine, high in positioning precision, easy to operate and capable of being recycled.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a positioning device for anchor bolts at column bases and a construction method thereof. Background technique [0002] With the wide application of steel structure buildings, it is often necessary to use column foot anchors to fix building steel columns or equipment in the foundation construction of construction projects. However, during the construction process, the on-site problems caused by the inaccurate positioning of the anchor bolts at the column feet are one of the most frequently reported problems in the construction of steel structures.

Problems solved by technology

However, during the construction process, the on-site problems caused by the inaccurate positioning of the anchor bolts at the column feet are one of the most frequently reported problems in steel structure construction.

Due to the uneven level of the construction team, the responsibilities of the civil engineering party and the steel structure party for pre-embedded anchor bolts are not clear, the disadvantages of making traditional anchor bolt positioning molds, and the concrete is easy to squeeze the anchor bolts and cause deviations, etc. Affected by the impact, the pre-embedded deviation of the anchor bolt is far greater than the allowable deviation range of the national standard (the national acceptance standard allows the center deviation of the anchor bolt at the foot of the column to be 5mm, but the actual construction of the project often reaches several centimeters or even tens of centimeters or more). Construction quality and safety have brought great hidden dangers

The positioning mold of the traditional anchor bolt is time-consuming, labor-intensive and has a large error. As a result, the pre-embedded effect of the anchor bolt at the column foot is often not good, and the mold steel plate has small holes, which is not conducive to the concrete vibration on site, and may easily cause uneven vibration. , not dense, etc., the disadvantages are obvious

Construction personnel often repeat rectification and rework for this, which consumes a lot of time, energy and cost, thus affecting the quality, safety and progress of the project
