Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bolt measuring devices, and in particular to a bolt measuring and positioning device. Background Technology
[0002] Anchor bolts are widely used in industrial buildings. They are embedded in the foundation and connected to steel columns to complete the installation of the steel structure. With the continuous development of modern equipment, the accuracy requirements for anchor bolt embedding are gradually increasing, while the required construction period is also gradually shortening. Anchor bolt positioning measurements are mostly performed using visual methods, string lines, or instrumental methods. Visual methods have a large measurement error; although they are time-efficient, they are prone to significant errors. String lines are not suitable for situations where the distance between foundations is large. Instrumental methods offer high accuracy, but require the instrument to be re-erected for each foundation, which is time-consuming. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an anchor bolt measuring and positioning device, which can quickly position and measure the entire group of anchor bolts, solving the problems of inaccurate anchor bolt positioning and long measurement time.

[0018] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.
[0019] like Figure 1 As shown, this utility model provides an anchor bolt measuring and positioning device, including a device plate 1, a connecting rod 7, and a bolt measuring panel 8. The device plate 1 is a hollow plate frame structure, preferably a rectangular plate frame. A level bubble meter 4 is installed on the device plate 1 to determine whether the measuring device plate 1 is in a horizontal state. Scale scales 2 are respectively provided on two opposite sides of the upper surface of the device plate 1, and the scale scales 2 are used to measure the longitudinal position (X direction) of the bolt. Slide grooves 3 are formed on the upper surface of the device plate 1 on the inner side of the two scale scales 2. The slide grooves 3 are inverted T-shaped grooves. The connecting rod 7 has graduations on its body, and a sliding terminal 5 is fixedly connected to each end of the connecting rod 7. The sliding terminal 5 is an inverted T-shaped plate that matches the shape of the slide groove 3. The sliding terminal 5 is slidably inserted into the corresponding side of the slide groove 3 and moves linearly along the slide groove 3. A sliding terminal pointer 6 is fixed on the sliding terminal 5, and the sliding terminal pointer 6 faces the scale scale 2 to indicate the longitudinal graduation at its position.
[0020] Several horizontally placed bolt measuring panels 8 are slidably connected to the connecting rod 7. To ensure that the bolt measuring panels 8 remain in a horizontal position, the connecting rod 7 is a multi-faceted prism structure, such as a triangular prism, a quadrangular prism, or a pentagonal prism. Correspondingly, through holes are opened on the side walls of the bolt measuring panels 8, and the through holes are multi-faceted holes that match the cross-sectional shape of the connecting rod 7.
[0021] Please see Figure 2One side of the bolt measuring panel 8 has a U-shaped opening structure. The U-shaped opening is used to hold the anchor bolt. A vertically placed laser emitter 83 (such as a laser pointer) is installed on the inner wall of the bottom of the U-shaped opening opposite to the opening position. The laser emission port of the laser emitter 83 faces vertically downward. By emitting a laser perpendicular to the bolt measuring panel 8, the perpendicularity of the anchor bolt (Z-axis direction) is measured. A through reading hole 82 is opened on the bolt measuring panel 8 on the opposite side of the U-shaped opening. The scale value on the connecting rod 7 can be observed through the reading hole 82. A bolt measuring panel pointer 81 is installed on one side of the reading hole 82. The bolt measuring panel pointer 81 faces the reading hole 82, indicating the horizontal position (Y-axis direction) of the connecting rod 7.
[0022] Adjustable bases 9 are also provided at the four corners of the lower surface of the device plate 1. The adjustable bases 9 include two implementation methods:
[0023] Please see Figure 3 The first type: The adjustable base 9 includes an adjustable base support 91, an adjustable base screw 92, a first bearing 11, and an adjustable base plate 93. The adjustable base plate 93 is fixedly connected to the lower end of the adjustable base support 91. The adjustable base support 91 has a vertical threaded hole inside, and the adjustable base support 91 is threadedly connected to the adjustable base screw 92 through the threaded hole. The upper end of the adjustable base screw 92 is inserted into the inner ring of the first bearing 11 and fixedly connected to it. The outer ring of the first bearing 11 is fixed to the lower surface of the device plate 1. When it is necessary to adjust the height of any corner of the device plate 1, the adjustable base screw 92 is rotated, and the horizontality of the device plate 1 is adjusted by the extension or retraction of the adjustable base screw 92 relative to the adjustable base support 91.
[0024] Please see Figure 4The second method involves T-shaped base grooves 10 formed at the four corners of the lower surface of the device plate 1, with an adjustable base 9 slidably connected within each groove. Preferably, the base grooves 10 are positioned at a 45° angle from the top corner. The adjustable base 9 includes an adjustable base support 91, an adjustable base screw 92, a rotating bearing 12, a limiting plate 13, and an adjustable base bottom plate 93. The adjustable base bottom plate 93 is fixedly connected to the lower end of the adjustable base support 91. A vertical threaded hole is formed inside the adjustable base support 91, which is threadedly connected to the adjustable base screw 92 through the threaded hole. The upper end of the adjustable base screw 92 is inserted into and fixedly connected to the inner ring of the rotating bearing 12. The outer ring of the rotating bearing 12 is fixedly connected to the lower surface of the limiting plate 13. The limiting plate 13 is slidably inserted into the transverse groove of the base groove 10, allowing the adjustable base 9 to change position on the lower surface of the device plate 1 through the sliding of the limiting plate 13. In use, the adjustable base 9 is placed on top of the base template, and the adjustable base support 91 provides overall support. By sliding the adjustable base 9, the adjustable base plate 93 can be positioned within the adjustable range of the base slide groove 10 to ensure stable ground support and effective contact with the contact surface. To facilitate processing and installation, a large horizontal groove can be first opened on the lower surface of the device plate 1. The limiting plate 13 is placed in the horizontal groove, and a fixing plate is fixed to the horizontal groove on the lower surface of the device plate on both sides of the adjustable base screw 92. A channel is left between the fixing plates for the adjustable base screw 92 or the rotating bearing to pass through, forming a T-shaped groove with the horizontal groove, which limits the limiting plate 13 within the device plate 1 and prevents it from falling off.
[0025] Usage: Place the adjustable base 9 on the stable foundation template, and adjust the adjustable base screws 92 one by one to center the bubble in the horizontal bubble meter 4 on the device plate 1, so that the device plate 1 is in a horizontal state; adjust the position of the connecting rod 7 through the sliding terminal 5, and use the reading of the scale 2 to ensure that the longitudinal position of the connecting rod 7 meets the design requirements and stop moving the sliding terminal 5. If necessary, wedges can be used to temporarily fix the sliding terminal 5 at both ends; next, adjust the position of the bolt measuring panel 8 to ensure that the lateral position meets the design requirements, thereby achieving precise positioning of the bolts and installing the anchor bolts.
[0026] After the anchor bolts are installed, move the bolt measuring panel 8 so that the anchor bolt is located in the groove of the bolt measuring panel 8, with the outer wall of the bolt tightly against the U-shaped opening of the bolt measuring panel. The pointer 81 of the bolt measuring panel reads the value through the reading hole 82 of the bolt measuring panel, thereby verifying the lateral position of the anchor bolt. Turn on the laser emitter 83 to emit a vertical beam of light perpendicular to the bolt measuring panel 8. Adjust the verticality of the anchor bolt by using the vertical beam of light to meet the requirements. At this point, one of the anchor bolts in the group has been accurately positioned. The other anchor bolts are then positioned longitudinally and laterally according to the above operation, thereby realizing the positioning measurement of the entire group of anchor bolts. According to the drawings, the positioning measurement of other groups of the same anchor bolts can be performed without adjusting the positioning measuring device.
[0027] This device can perform positioning and measurement of an entire group of anchor bolts, and can be operated by one person to continuously measure identical anchor bolts.
[0028] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
