[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown in the figure, a gate embedded part installation and positioning device provided by a specific embodiment of the present invention includes an adjusting base 1 and a stud assembly, wherein, The stud assembly includes a stud 2, a first hollow sleeve 3, and a second hollow sleeve 4. One end of the stud 2 is integrally formed with a ball head 9. One end of the first hollow sleeve 3 is used to fit onto the outer circumferential surface of the other end of the stud 2. One end of the second hollow sleeve 4 is used to fit into the other end of the first hollow sleeve 3. The second hollow sleeve 4 is provided with a radially penetrating clamping hole for installing a clamping screw 8. One end face of the adjusting base 1 is provided with a slot that mates with the ball head 9, and the other end face of the adjusting base 1 opposite to the slot is provided with a level bubble 5.

[0020] Specifically, two level bubbles are set on the top surface of the base 1. After the base 1 is connected, the height and level can be adjusted: the height is adjusted by using the first hollow sleeve 3 and the second hollow sleeve 4, and the level bubbles are observed to determine whether the plane of the base is level.

[0021] Furthermore, a locking element is provided at the slot, which is a pressure plate + bolt or wedge + bolt structure, used for surface contact locking after alignment is completed.

[0022] Furthermore, after the adjustment is completed, the bottom sill can be placed on top of the adjustment base 1 and fixed by welding or secondary reinforcement using the original adjustment plate and the bottom sill. This allows for the rapid positioning, leveling and centering of horizontal embedded parts such as the bottom sill even when there is a large deviation in the reinforcing bar.

[0023] Based on the above basic implementation method, the adjustment base 1 also includes a laser through hole 6 that is disposed through the thickness direction of the adjustment base 1, and the laser through hole 6 is configured as two spaced apart from each other.

[0024] Specifically, the inner circumferential surface of one end of the first hollow sleeve 3 is provided with an internal thread for threaded connection with the end of the stud 2 during the installation of the embedded part.

[0025] In one specific embodiment, the inner circumferential surface of one end of the second hollow sleeve 4 is provided with an internal thread for connecting with the first hollow sleeve 3 during the installation of the embedded part; the outer circumferential surface of the first hollow sleeve 3 is provided with a locking nut for locking the position of the stud 2 after the position adjustment of the first hollow sleeve 3 is completed.

[0026] In this embodiment, the slot is an arc-shaped slot and the opening direction of the slot is along the length direction of the adjusting base, so that the ball head 9 can be inserted into the slot from the opening during the installation of the embedded part.

[0027] Furthermore, the arc surface of the arc-shaped slot is a spherical or cylindrical-spherical composite surface structure, which enables the ball head 9 to have multi-degree-of-freedom fine adjustment capabilities relative to the adjustment base, including pitch, yaw, and small-range translation.

[0028] In another specific embodiment, the level bubble 5 includes at least two, and the sensitive axes of the two are arranged orthogonally to each other; the clamping hole is provided with an internal thread for threaded connection with the clamping screw.

[0029] Specifically, when the device is used for vertical embedded part installation, a lateral installation position is provided to install at least one of the leveling bubbles 5 to the side of the adjusting base 1 for adjusting the vertical direction of plumb correction.

[0030] In one specific embodiment, a handwheel is provided on the clamping screw 8, and a clamping element is provided at one end of the clamping screw 8 facing the second hollow sleeve 4; the level bubble side of the adjusting base 1 is engraved with connecting lines and scale marks at the corresponding positions of the laser through hole 6, and a detachable laser centering device is provided in the laser through hole 6, and the laser beam of the laser centering device can be seen on both the stud side and the level bubble side of the adjusting base 1 when the embedded part is installed.

[0031] In this embodiment, the adjusting base 1 is an integral beam-shaped component that spans two sets of anchoring components. The bottom surface is provided with reinforcing ribs, and the top surface is provided with a sill support step or anti-slip texture. The length of the beam-shaped component is replaceable or telescopic to accommodate the first-stage reinforcing bars with different spacing. The load-bearing structure of the adjusting base 1 is designed with a margin of not less than the sill's own weight and the additional load during installation. The bottom or side surface is provided with lifting holes / handle holes to meet the needs of handling and temporary load-bearing of sills weighing not less than 1,000 kg. At the same time, weight reduction is achieved through opening holes and the arrangement of reinforcing ribs.

[0032] Specifically, the laser beam can be seen from the bottom to the top; the scale markings include equidistant lines based on the line connecting the centers of the two through holes and X1 and X2 counting marks, which are used to quickly draw and determine the center line of the door slot under two working conditions: whether the theoretical baseline and the layout line coincide or not; the clamping part is a pressure point or a hemispherical end, and can be used with an arc-shaped pad to improve the anti-slip clamping force on the insert.

[0033] In another specific embodiment, the device operates as follows: According to the positions of the two first-phase reinforcing bars, install the two sets of anchoring components respectively and lock them with clamping screws and handwheels; insert the stud ball head 9 from the side of the arc-shaped slotted seat on the back of the adjusting base 1 and initially lock it to fix the two sets of anchoring components to the adjusting base; rotate the first and second hollow sleeves and cooperate with the locking nut 7 to adjust the elevation and level of the adjusting base 1 until the level bubble 5 indicates qualified; arrange the laser centering device in the laser through hole 6, and determine the center line of the door slot according to the center of the two through holes and the scale mark on the top surface, according to the two cases of the theoretical baseline and the layout line coinciding or not coinciding, to achieve the centering of the bottom sill; place the bottom sill on the adjusting base 1 and re-measure the elevation, level and centering. After passing the test, use the original adjusting plate to weld and fix the bottom sill or perform secondary reinforcement.

[0034] Furthermore, when used for the installation of vertical embedded parts such as main rails / reverse rails, the level bubble 5 is converted and installed on the side of the adjustment base 1, and the vertical plane position is controlled by the distance of the infrared centering device relative to the bottom sill baseline, thus completing the positioning and locking of the guide rail.

[0035] Furthermore, the installation steps for the vertical embedded parts are as follows: Remove the level bubble 5 from the top surface and install it in the reserved position on the side of the adjusting base 1, so that its sensitive axis is used for plumb correction and the bubble zero position is checked; install adjustable supports in the two laser through holes 6 and adjust the height so that the optical axes of the two holes are at the same design line elevation; mark the bottom sill baseline D0 on the structural surface. If D0 is not on the same plane as the device's graduated plane, equidistant lines of D0 can be drawn in the graduated area on the top surface of the device according to the known offset, as a reading reference; install the two sets of anchoring components on the two primary reinforcing bars respectively. The second hollow sleeve 4 clamps the insert rib with clamping screws 8 and clamping parts; the stud ball head is inserted into the arc groove from the side of the adjusting base 1, and the locking part is initially kept in a lightly locked state; the first hollow sleeve 3 and stud 2 are rotated to complete the initial adjustment of height and extension, so that the adjusting base 1 is near the design position of the guide rail; the side-mounted level bubble 5 is observed, and the two sets of anchoring components are finely adjusted to make the adjusting base 1 basically horizontal in the vertical plane. The guide rail is temporarily supported on the support surface of the adjusting base 1 or on a temporary tooling, and fixed with soft clamps or straps; when D0 coincides with the theoretical center line of the guide rail, the two-hole light source is turned on, the center projection points of the two holes are read in the engraved area and connected to obtain the measurement baseline of the device. Adjust the position and attitude of the device to make the baseline coincide with D0 or maintain the design relationship; when D0 does not coincide with the theoretical center line of the guide rail and the offset d is known, use the through hole near D0 as the drawing point, mark the point at a distance d along the normal scale, obtain the corresponding point for the other hole in the same way, and connect the points to obtain the target line of the guide rail. Adjust the position and attitude of the device to make the working surface of the guide rail meet the design offset relative to the target line; slightly loosen the locking part at the ball head slot, and make slight displacement or rotation under universal joint. After the offset meets the requirements, fully lock the ball head slot and tighten the locking nut of the first hollow sleeve 3 to make the system rigid; check whether the vertical plane where the guide rail is located is horizontal by using the side-mounted level bubble 5; use a digital inclinometer, plumb bob, or laser plumb line to check the plumbness along the entire length of the guide rail. It is recommended that the single-trip error not exceed 0.5 mm per meter, and the cumulative error not exceed 1 mm. If torsion or forward / backward sway occurs, adjust the differential extension using two sets of anchoring components, and correct it using the pitch and yaw degrees of freedom of the ball head slot. After the offset and plumb line meet the standards, perform tack fixing and final fixing in the order from the middle to both ends. After welding or final tightening, re-measure. If there is springback, make minor corrections before final fixing. Adjust the height of the two infrared supports to ensure that the two optical axes are at the same elevation. If necessary, install a liftable outer sleeve with a range of 0 to 30 mm outside the through hole. Absorb the height difference through the differential extension of the two sets of anchoring components, while keeping the side-mounted level bubble centered.

[0036] To aid in a better understanding of the present invention, a more comprehensive and specific embodiment is described, in which the present invention provides an installation and positioning device for a gate embedded component, comprising an adjusting base 1 and a stud assembly, wherein... The stud assembly includes a stud 2, a first hollow sleeve 3, and a second hollow sleeve 4. One end of the stud 2 is integrally formed with a ball head 9. One end of the first hollow sleeve 3 is used to fit onto the outer circumferential surface of the other end of the stud 2. One end of the second hollow sleeve 4 is used to fit into the other end of the first hollow sleeve 3. The second hollow sleeve 4 is provided with a radially penetrating clamping hole for installing a clamping screw 8. One end face of the adjusting base 1 is provided with a slot that mates with the ball head 9, and the other end face of the adjusting base 1 opposite to the slot is provided with a level bubble 5.

[0037] In this embodiment, the adjusting base 1 also includes a laser through hole 6 that runs through the thickness direction of the adjusting base, and the laser through holes 6 are arranged in two spaced apart from each other; the inner circumferential surface of one end of the first hollow sleeve 3 is provided with an internal thread for threaded connection with the end of the stud 2 during the installation of the embedded part; the inner circumferential surface of one end of the second hollow sleeve 4 is provided with an internal thread for connection with the first hollow sleeve 3 during the installation of the embedded part; the outer circumferential surface of the first hollow sleeve 3 is provided with a locking nut 7 for locking the position of the stud 2 after the position adjustment of the first hollow sleeve 3 is completed; the slot is an arc-shaped slot and the opening direction of the slot is along the length direction of the adjusting base 1, so as to insert the ball head 9 into the slot from the opening during the installation of the embedded part; the level bubble 5 includes at least two, and the sensitive axes of the two are orthogonally arranged to each other.

[0038] Specifically, the clamping hole is provided with an internal thread for threaded connection with the clamping screw 8; the clamping screw 8 is provided with a handwheel, and a clamping element is provided at the end of the clamping screw 8 facing the second hollow sleeve 4; the level bubble side of the adjusting base 1 is engraved with connecting lines and scale marks at the corresponding position of the laser through hole 6, and a detachable laser centering device is provided in the laser through hole 6, and the laser beam of the laser centering device can be seen on both the stud side and the level bubble side of the adjusting base 1 when the embedded part is installed.

[0039] In summary, the embodiments disclosed herein have at least the following technical effects: By using precise studs and ball heads in conjunction with the slotted structure, significant deviations (including errors in planar position and direction) in the initial reinforcement insertion during civil construction can be effectively compensated. An adjustment device allows embedded parts (such as bottom sills and guide rails) to be conveniently and quickly positioned and precisely aligned during installation, ensuring consistency with the center of the door slot, the center of the opening, and the design elevation, thus solving the alignment difficulties caused by reinforcement insertion deviations in traditional techniques. The device employs a ball-head 9 with a slotted design, allowing the stud 2 to rotate at multiple angles during installation, providing sufficient freedom for fine adjustments. Through the coordination of the level bubble 5 and the laser centering device, precise adjustments in both horizontal and vertical directions can be achieved, reducing errors from manual adjustments and improving adjustment efficiency. Because the device is designed to be modular and detachable, all components (such as the first hollow sleeve, the second hollow sleeve, clamping screws, etc.) can be reused, which reduces equipment costs and improves the economic efficiency of the construction site. In traditional construction processes, deviations in the placement of reinforcing bars directly affect the installation accuracy of embedded parts. This invention, however, effectively compensates for these deviations through an adjustable stud structure and clamping device. Whether the reinforcing bar is vertical or horizontal, this device ensures accurate positioning of the embedded part, thereby improving installation quality and safety. The laser through-hole 6 and detachable laser centering device on the device not only make the centering process more intuitive, but also enable rapid centering and positioning through the visible range of the laser beam on the stud side and the level bubble side, avoiding the cumbersome steps in traditional measurement methods and greatly improving work efficiency and centering accuracy.

[0040] This device integrates multiple functions such as bubble level, laser centering, and clamping screws, avoiding the tedious process of multiple adjustments and verifications required in traditional methods. Construction personnel can complete precise installation with simple operations (such as adjusting screws and observing the bubble and laser), saving a lot of time and manpower.

[0041] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
