Description

Bolt installation anti-deviation tool and method Technical Field The invention relates to the field of bolt installation, in particular to a bolt installation deviation prevention tool and a method. Background In the construction of building engineering, the civil engineering and the steel structure engineering, the civil engineering and the equipment installation engineering all relate to bolt installation, and particularly, when the metallurgical civil engineering is constructed, a large quantity of embedded bolts are adopted. The embedded bolts become an irreplaceable construction technology for the connection of civil engineering and steel structures and the connection of civil engineering and mechanical equipment in the future. In recent years, the requirements on the quality of the building engineering are more and more strict, and the installation precision of steel structures and equipment is also more and more refined. Especially when a huge number of embedded bolts are required to be installed, the progress and quality of engineering projects are greatly reduced, and a scientific and reasonable bolt construction process is an important guarantee for construction quality and engineering quality. During civil engineering construction, the embedded bolts always have problems of common quality in actual construction, such as serious deviation of adjacent embedded bolts and large scale height error of the embedded bolts, and unavoidable safety and quality hidden trouble are reserved for subsequent construction. After the steel bar binding and the template mounting are completed in the civil construction process, a total station casting mode is generally adopted, an independent steel bar frame needing to be embedded is welded on the foundation, the accurate position of a bolt is measured by a tape measure and marked on the steel bar frame, then the line is hung on the frame in sequence, and the embedded bolts are welded in sequence. When the process is used for construction, when the distance is slightly long, the superposition measurement is carried out, and the wind force is large, the error of the embedded bolt is often large, and the line is easily touched by other personnel by mistake to cause serious deviation, the construction sequence is tedious and the excessive manpower and time are wasted. Disclosure of Invention The invention provides a bolt installation deviation prevention tool and a bolt installation deviation prevention method, which can solve the problem of deviation during bolt installation on a construction site. The embodiment of the invention provides a bolt installation deviation-preventing tool, which is used for installing a bolt on a foundation and comprises a template, wherein the outer contour shape of the template is the same as that of the foundation, a screw hole is arranged on the template, and the distance and the direction between the central line of the screw hole and the central line of the outer contour of the template are the same as those between the central line of the installation position of the bolt on the foundation and the central line of the outer contour of the foundation. In some of these embodiments, the dimensions of the template are the same as the dimensions of the base. In some of these embodiments, the size of the template is smaller than the size of the base. In some of these embodiments, the inner diameter of the threaded bore is greater than the outer diameter of the shank of the bolt. In some of these embodiments, the form comprises a wood form or a steel plate. The embodiment of the invention provides a bolt installation deviation prevention method for installing a bolt on a foundation, which comprises the following steps of providing a template. The outer contour shape of the template is the same as the outer contour shape of the foundation. And drilling a screw hole on the template, and enabling the distance and the direction between the central line of the screw hole and the central line of the outer contour of the template to be the same as the distance and the direction between the central line of the installation position of the bolt on the foundation and the central line of the outer contour of the foundation. The center line of the outer contour of the template is overlapped with the center line of the outer contour of the foundation. The bolts are passed through the screw holes, and then the bolts are connected with the base. In some of these embodiments, the drill locations of the screw holes are marked on the template before the screw holes are drilled on the template.
