Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a convenient auxiliary device for pre-embedding anchor bolts. Background Technology

[0002] Anchor bolts are screw-like rods used to fasten equipment and other equipment to a concrete foundation. They are commonly used in infrastructure projects such as railways, highways, power plants, factories, mines, bridges, tower cranes, long-span steel structures, and large buildings. In actual construction, anchor bolts are typically pre-fixed at the four corners, and then concrete is poured around the lower ends of the anchor bolts. After the concrete hardens, the anchor bolts are embedded in it. However, existing pre-embedding auxiliary devices have low pre-fixing accuracy and can usually only pre-fix one type of anchor bolt. In actual construction, however, various diameters of anchor bolts are used, resulting in poor flexibility and difficulty in meeting actual construction needs. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient anchor bolt pre-embedding auxiliary device. When using this device, the mounting components are placed above the anchor bolt pre-embedding area via a support frame. Based on the diameter of the anchor bolt to be installed, the number of straightening tube layers is selected so that the inner diameter of the uppermost straightening tube matches the diameter of the anchor bolt. The mounting sleeve is then rotated until the straightening tube is in the desired position, and then the locking device is used to lock the mounting sleeve onto the mounting post. Finally, the anchor bolt is passed through the straightening tube from bottom to top and threadedly connected to the hanging nut. The anchor bolt is then hung on the straightening tube using the hanging nut. This device is suitable for pre-embedding anchor bolts of different specifications, offering high pre-fixing accuracy and good flexibility.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A convenient anchor bolt pre-embedding auxiliary device includes a support frame and an installation assembly. The support frame includes a cross plate and support feet respectively disposed at the four corners of the cross plate. The installation assembly includes an installation column, an installation sleeve, and four installation units. The upper end of the installation column is fixedly connected to the intersection of the cross plate. The installation sleeve is rotatably disposed at the lower end of the installation column and is locked to the installation column by several locking components. The installation units are respectively disposed at the four outer corners of the installation sleeve. Each installation unit includes multiple overlapping straightening tubes, the inner diameter of which increases from top to bottom. The lower inner edge of the upper straightening tube is fixed with a connecting protrusion ring, which tightly embeds into the lower straightening tube to detachably connect the adjacent straightening tubes together. The lowermost straightening tube is fixedly connected to the installation sleeve by a connector. The upper end of the anchor bolt tightly passes through the upper end of the straightening tube with a matching inner diameter and is threadedly connected to the hanging nut. The anchor bolt is hung on the straightening tube by the hanging nut.

[0006] Furthermore, a locking nut is threaded onto the anchor bolt below the straightening tube, and the straightening tube is tightly clamped between the hook nut and the locking nut.

[0007] Furthermore, the connecting component includes a fixed square tube, a movable square rod, and a positioning bolt; the inner end of the fixed square tube is fixedly connected to the side wall of the mounting sleeve, and the outer end of the fixed square tube is sleeved on the movable square rod; the outer end of the movable square rod is fixedly connected to the side wall of the lowest straightening tube; the positioning bolt is threaded to the outer end of the fixed square tube and its inner end is tightly abutted against the movable square rod, and the movable square rod is locked onto the fixed square tube by the positioning bolt.

[0008] Furthermore, the movable square rod is provided with a scale for observing the length of the movable square rod extending outward from the fixed square tube.

[0009] Furthermore, the locking component is a locking bolt, which is threadedly connected to the mounting sleeve and its inner end is tightly pressed against the mounting post. The mounting sleeve is locked onto the mounting post by the locking bolt.

[0010] Furthermore, the support foot includes a support rod, a support tube, and two adjusting nuts; the upper end of the support rod is threaded to the support tube, and the length of the support foot is adjusted by rotating the support rod; the support tube passes through the cross plate, and the adjusting nuts are threaded to the support tubes on both sides of the cross plate, and the height of the cross plate mounted on the support tube is adjusted by rotating the adjusting nuts.

[0011] Furthermore, a pad is fixed to the lower end of the support rod to increase the contact area with the ground.

[0012] Furthermore, the lower end of the support rod is provided with an installation hole, the upper end of a stabilizing nail is threaded to the installation hole, and the lower end of the stabilizing nail is inserted into the soil.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1. This utility model discloses a convenient anchor bolt pre-embedding auxiliary device. In use, the installation component is placed above the anchor bolt pre-embedding area using a support frame. The number of straightening tube layers is selected according to the diameter of the anchor bolt to be installed, ensuring that the inner diameter of the uppermost straightening tube matches the diameter of the anchor bolt. The installation sleeve is then rotated until the straightening tube is in the desired position, and a locking device is used to lock the installation sleeve onto the installation column. Finally, the anchor bolt is passed through the straightening tube from bottom to top and threadedly connected to the hook nut. The anchor bolt is then hung on the straightening tube using the hook nut. The straightening tube can also straighten and orient the anchor bolt, limiting its lateral movement. This device is suitable for pre-embedding anchor bolts of different specifications, offering high pre-fixing accuracy and good flexibility.

[0015] 2. This utility model provides a convenient auxiliary device for pre-embedding anchor bolts. The straightening tube is tightly clamped between the hook nut and the locking nut, which can restrict the up-and-down movement of the anchor bolts. At the same time, the length of the moving square rod extending outward from the fixed square tube can be observed through the scale, and the moving square rod is locked to the fixed square tube by the positioning bolt. The installation distance of the four anchor bolts can be adjusted according to actual needs, which is highly flexible.

[0016] 3. This utility model provides a convenient anchor bolt pre-embedding auxiliary device. The stabilizing nail can be detachably installed at the lower end of the support rod. When the soil is hard, the stabilizing nail can be omitted and the support rod can be supported by a pad. When the soil is relatively soft, the stabilizing nail can be inserted into the soil and supported on the ground by the pad, which can make the support foot installation more stable. In addition, the length of the support foot can be roughly adjusted by rotating the support rod, and the height of the cross plate installed on the support tube can be finely adjusted by rotating the adjusting nut. It is easy to operate and has good performance. Attached Figure Description
