AI Technical Summary
During the installation and construction of steel columns, professional wrenches are difficult to operate freely under limited space, which affects the tightening of anchor bolts, and professional wrenches need to be purchased in advance.
A fastening handle is designed, including a handle, adapter, bolt, fastening plate and nut. By placing the fastening handle on the anchor bolt, the nut is used to drive the fastening plate to move the inner side and through the handle. Horizontal rotation tightens the anchor nut to achieve tightening of the anchor bolts.
The fastening handle is simple to assemble and easy to operate. It does not require the purchase of professional wrench in advance. It can operate freely in limited space, ensuring the tightening of anchor bolts and reducing construction costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of steel column installation construction, and in particular provides a foundation bolt tightening handle. Background Art
[0002] During the installation and construction of steel columns, the anchor bolts of the steel columns are generally tightened with professional wrenches. The disadvantages of this method are: first, it is necessary to purchase professional tightening wrenches in advance; second, professional wrenches sometimes cannot be operated freely in confined spaces, thus affecting the tightening of the anchor bolts. Utility Model Content
[0003] The utility model aims to provide a foundation bolt fastening handle, which solves the problem of fastening bolts in a limited space.
[0004] The utility model places the tightening handle on the anchor bolt so that the anchor nut is between the adapter plate and the tightening plate, and then screws the two nuts at the same time, the nuts drive the tightening plate to move inward until the tightening plate presses against the anchor nut, and then operates the handle to rotate the tightening handle horizontally, so that the anchor nut is rotated downward and screwed until the anchor nut is tightened.
[0005] The utility model fastening handle comprises a handle 1, an adapter plate 2, a bolt rod 3, a fastening plate 4, and a nut 5, which are used in combination. The handle 1 is vertically welded to the bottom surface of the adapter plate 2; one end of the two bolt rods 3 is respectively welded to the two side surfaces of the adapter plate 2; the fastening plate 4 passes through the two bolt rods 3 and can move; the two nuts 5 are respectively screwed into the two bolt rods 3 (see Figure 1 , Figure 2 ).
[0006] Among them, the handle 1 is made of round steel with a diameter of 30mm and a length of 200mm; the adapter plate 2 is made of a 20mm thick steel plate, with a size (length*width) of 60mm*30mm; the bolt rod 3 is 12mm in diameter and 80mm in length; the fastening plate 4 is made of a 14mm thick steel plate, with a size (length*width) of 100mm*30mm; the nut 5 is 12mm in diameter.
[0007] When in use, place the tightening handle on the anchor bolt 6, so that the anchor nut 7 is between the adapter plate 2 and the tightening plate 4, and then screw the two nuts 5 at the same time, the nuts 5 drive the tightening plate 4 to move inward until the tightening plate 4 presses against the anchor nut 7, and then operate the handle 1 to rotate the tightening handle horizontally to rotate the anchor nut 7 downward until the anchor nut 7 is tightened (see Figure 3 , Figure 4 ).
[0008] The utility model has the advantages of simple assembly and convenient operation, and does not need to purchase a professional wrench in advance, is not restricted by limited space, can be operated freely, ensures the tightening of the anchor bolts, and reduces the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 Front view of the fastening handle.
[0011] Figure 3 Use the top view for tightening the handle.
[0012] Figure 4 Use the front view for tightening the handle.
[0013] In the figure, there are a handle 1, an adapter plate 2, a bolt rod 3, a fastening plate 4, a nut 5, an anchor bolt 6, and an anchor nut 7. DETAILED DESCRIPTION
[0014] Figure 1-Figure 4 This is a specific implementation of the utility model. The utility model is further described below in conjunction with the accompanying drawings.
[0015] The utility model fastening handle comprises a handle 1, an adapter plate 2, a bolt rod 3, a fastening plate 4, and a nut 5, which are used in combination, the handle 1 is vertically welded to the bottom surface of the adapter plate 2; one end of the two bolt rods 3 are respectively welded to the two side surfaces of the adapter plate 2; the fastening plate 4 passes through the two bolt rods 3 and is movable; the two nuts 5 are respectively screwed into the two bolt rods 3.
[0016] When in use, place the tightening handle on the anchor bolt 6 so that the anchor nut 7 is between the adapter plate 2 and the tightening plate 4, then screw the two nuts 5 at the same time, the nuts 5 drive the fastening plate 4 to move inward until the fastening plate 4 presses against the anchor nut 7, then operate the handle 1 to rotate the tightening handle horizontally to rotate the anchor nut 7 downward until the anchor nut 7 is tightened.
[0017] During the installation and construction of the steel column of the main workshop of the rolling mill, a tightening handle was used to tighten the anchor bolts of the steel column. It does not require the purchase of a professional wrench in advance, and is not restricted by the limited space. It can be operated freely, ensuring the tightening of the anchor bolts. It is convenient and fast, and has a good effect. The tightening handle is used in combination, and the handle is vertically welded to the bottom surface of the adapter plate; one end of the two bolt rods is respectively welded to the two sides of the adapter plate; the fastening plate passes through the two bolt rods and can move; the two nuts are respectively screwed into the two bolt rods. When in use, the tightening handle is placed on the anchor bolt so that the anchor nut is between the adapter plate and the fastening plate, and then the two nuts are screwed at the same time. The nuts drive the fastening plate to move inward until the fastening plate presses against the anchor nut, and then the operating handle is horizontally rotated to rotate the tightening handle so that the anchor nut is rotated downward until the anchor nut is tightened. The tightening handle is simple to assemble and easy to operate. It does not require the purchase of a professional wrench in advance, and is not restricted by the limited space. It can be operated freely, ensuring the tightening of the anchor bolts and reducing the construction cost.
