Description

Technical Field

[0001] This application relates to the field of welding bracket technology, and in particular to an adjustable welding bracket for steel panel mounting. Background Technology

[0002] In construction projects, industrial equipment installation, and other scenarios, the installation quality of steel panels directly affects the reliability of subsequent welding operations, concrete pouring, and other processes. As the core support component for steel panel installation, the positioning accuracy, temporary fixing stability, and ease of height adjustment of the bracket are key to ensuring installation quality.

[0003] During the installation of steel panels, the height needs to be precisely adjusted using brackets, and the steel panels need to be firmly and temporarily fixed to prevent slippage or displacement during welding and subsequent construction processes, ensuring that the installation elevation, levelness and relative position of the steel panels meet the design requirements.

[0004] For example, patent CN107965118A discloses a circular steel bracket for supporting load-bearing panels that can be suspended. The support structure consists only of a circular steel disc, a large nut column, and a small nut column. Although it can achieve the suspended installation and foundation support of the load-bearing panels, it relies solely on the load-bearing structure of the components themselves to support the panels.

[0005] When this structure is used for welding steel panels, the steel panels are prone to slippage under welding tension or slight disturbance because the position of the steel panels is not limited, which affects the installation accuracy of the steel panels. Utility Model Content

[0006] To improve the installation accuracy of steel panels, this application provides an adjustable welding bracket for steel panel installation.

[0007] This application provides an adjustable welded bracket for mounting steel panels, which adopts the following technical solution: An adjustable welded bracket for mounting steel panels, comprising: Base, height adjustment mechanism, support plate for supporting the steel panel, and positioning mechanism; The height adjustment mechanism is mounted on the base and is used to adjust the height of the support plate. The positioning mechanism includes a support rod, a first threaded rod, and a positioning block. The support rod is located at the edge of the support plate, and the first threaded rod is threadedly connected to the support rod. The positioning block is located on the bottom end face of the first threaded rod, and the steel panel has a positioning hole corresponding to the position of the positioning block.

[0008] By adopting the above technical solution, when installing the steel panel, the four corners of the steel panel are first placed stably on the support plates of four adjustable welding brackets. The four support plates correspond one-to-one with the four corners of the support plate. The operator rotates the first threaded rod, and by utilizing the threaded engagement between the first threaded rod and the support rod, the first threaded rod moves downward along the axial direction of the support rod. This causes the bottom positioning block to gradually penetrate into the positioning hole on the steel panel, thereby achieving the positioning and temporary fixation of the steel panel. Since the four positioning blocks extend into the positioning holes at the four corners of the steel panel and support the positioning holes, the steel panel will not shift during the welding process, ensuring the stability of the steel panel position during welding and improving the installation accuracy of the steel panel. After the steel panel is welded, the first threaded rod is rotated in the opposite direction to cause the positioning blocks to detach upward from the surface of the steel panel, thus releasing the temporary fixation.

[0009] Optionally, the positioning block is cone-shaped, with a cross-sectional area at the end near the steel panel being larger than the cross-sectional area at the end away from the steel panel, and the diameter of the positioning hole on the steel panel is larger than the minimum cross-sectional area of ​​the positioning block.

[0010] By adopting the above technical solution, the conical structure can improve the uniformity of contact pressure and reduce the risk of deformation caused by excessive local stress on the steel panel; moreover, the conical structure facilitates the adjustment of the position of the steel panel. During steel panel welding, the tapered structure can constrain the steel panel, effectively resisting the tensile force generated during welding or the slippage of the steel panel caused by slight external disturbances, further improving the reliability of temporary fixation.

[0011] Optionally, the positioning mechanism further includes an auxiliary clamping assembly, which includes a fixing ring and a clamping pad. The fixing ring is disposed on the positioning block, and the clamping pad is disposed on the fixing ring.

[0012] By adopting the above technical solution, during the movement of the positioning block towards the steel panel, the fixing ring moves down synchronously with the positioning block. The bottom pressing pad first comes into contact with the surface of the steel panel. As the first threaded rod continues to tighten, the positioning block gradually locks into the positioning hole on the steel panel. The pressing pad is squeezed and undergoes elastic deformation, forming a secondary buffer pressing effect. The pressing pad is made of elastic materials such as rubber and silicone, which can avoid direct rigid contact between the positioning block and the steel panel and effectively prevent the surface of the steel panel from being scratched.

[0013] Optionally, it also includes two welding plates and a welding plate disassembly mechanism. The welding plate disassembly mechanism includes a second threaded rod and a nut. The support plate and the steel panel are respectively provided with two limiting grooves that match the welding plates on two sides corresponding to one corner edge. The two welding plates are respectively disposed in the limiting grooves. The second threaded rod is disposed at the bottom of the welding plate and passes through the support plate. The nut is threadedly connected to the second threaded rod.

[0014] By adopting the above technical solution, after the steel panel is temporarily fixed, the welding plate is attached to the edge of the steel panel and serves as a welding transition part to assist in completing the welding operation. After the welding is completed, concrete needs to be poured onto the steel panel. After the concrete solidifies, the weld point needs to be cut to facilitate the separation of the support plate from the steel panel for subsequent use. Since there are residues after the weld point is cut, the operator rotates and unscrews the nut to remove the welding plate from the support plate, which facilitates the operator to clean up the weld point residue and avoids the weld point residue affecting the next welding effect.

[0015] Optionally, the height adjustment mechanism includes a threaded sleeve, an adjusting screw, a guide sleeve, and a guide rod. The threaded sleeve and the guide sleeve are both disposed on the base. The adjusting screw is disposed at the bottom of the support plate and threadedly connected to the threaded sleeve. The guide rod is disposed at the bottom of the support plate and slidably connected to the guide sleeve. The steel panel is disposed on the support plate.

[0016] By adopting the above technical solution, when the height of the support plate needs to be adjusted, the operator rotates the adjusting screw to drive the support plate to rise and fall vertically. During this process, the guide rod slides synchronously along the guide sleeve, restricting the rotational freedom of the support plate and ensuring that the support plate always remains horizontal during rise and fall. The threaded transmission structure has high adjustment precision and can achieve fine adjustment of the support plate height, meeting the precise elevation requirements for steel panel installation. The cooperation structure between the guide rod and the guide sleeve effectively prevents the support plate from tilting or shifting during the rising and falling process, ensuring the horizontality of the steel panel installation and providing a stable support foundation for subsequent welding and pouring processes.

[0017] Optionally, a polygonal knob is formed on the outer peripheral surface of the adjusting screw.

[0018] By adopting the above technical solution, when adjusting the adjusting screw, the wrench opening is placed against the side of the polygonal knob, and the torque is applied by the wrench to rotate the adjusting screw, thereby realizing the height adjustment of the support plate. This effectively avoids wrench slippage and improves the safety and convenience of the adjustment operation.

[0019] Optionally, the height adjustment mechanism further includes an indicator component, which includes a circular block and an axial indicator rod. The circular block is rotatably connected to the bottom of the adjusting screw. An axial indicator rod is provided on the outer circumferential surface of the circular block. An axial clearance hole is provided on the inner wall of the threaded sleeve corresponding to the position of the axial indicator rod. Height scale lines distributed along its length are engraved on the outer circumferential surface of the threaded sleeve. The top end of the axial indicator rod protrudes from the threaded sleeve, and a scale indicator mark adapted to the height scale lines is provided on the top end of the axial indicator rod.

[0020] By adopting the above technical solution, when adjusting the height of the support plate by rotating the adjusting screw, the adjusting screw drives the circular block to rise and fall synchronously, and the axial indicator rod moves vertically along the axial clearance hole of the threaded sleeve with the circular block. The operator can read the height adjustment of the support plate in real time by observing the corresponding position of the scale indicator mark at the top of the axial indicator rod and the height scale line on the outer circumference of the threaded sleeve. There is no need to rely on external measuring tools such as a level or tape measure, avoiding the tedious operation of repeated measurement and verification, and improving the efficiency of height adjustment. At the same time, the scale mark is clear and intuitive, which makes it easy for multiple sets of brackets to be adjusted to the same height at the same time, effectively ensuring the overall flatness of the steel panel installation.

[0021] Optionally, the base is provided with multiple heavy-duty casters at its bottom, and the base is provided with multiple fixing holes for locking the base position.

[0022] By adopting the above technical solution, when the support needs to be moved, the brake mechanism of the heavy-duty caster is unlocked, and the operator can push the support to adjust its placement position. After the support is moved to the preset installation position, the brake mechanism of the caster is depressed to lock the wheels, and then expansion bolts and other fasteners are inserted into the ground through the fixing holes on the base to achieve double locking of the base. The design of the heavy-duty caster is adapted to the weight requirements of the support, steel panel and subsequent concrete, making it easy and labor-saving to move and facilitating quick adjustment of the support position in complex construction environments. The double locking structure of the fixing holes and casters ensures that the support will not shift during installation, welding and pouring processes.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The conical positioning block of the positioning mechanism works in concert with the auxiliary clamping components to achieve rigid clamping and elastic buffering of the steel panel, which not only prevents the steel panel from slipping but also protects its surface from damage, providing a strong guarantee for welding accuracy. 2. The combination of threaded drive and guide structure ensures smooth lifting and lowering of the support plate. The polygonal knob design of the adjusting screw facilitates force application. The indicating component enables visual control of height adjustment without the need for external measuring tools, thus improving adjustment efficiency and accuracy. 3. A welding plate disassembly mechanism is provided, which allows the welding plate to be separated from the bracket, making it convenient to clean up the weld residue, preventing the weld residue from affecting the next welding, and improving the reusability of the bracket.

Detailed Implementation

[0026] The following combination Figure 1 , Figure 2 and Figure 3 This application will be described in further detail.

[0027] This embodiment discloses an adjustable welding bracket for mounting steel panels.

[0028] Reference Figure 1 and Figure 2 An adjustable welded bracket for mounting steel panels, comprising: The system includes a base 100, a height adjustment mechanism 200, a support plate 600 for supporting the steel panel 700, two welding plates 500, a welding plate disassembly mechanism 400, and a positioning mechanism 300. The height adjustment mechanism 200 is fixedly mounted on the base 100 to adjust the height of the support plate 600. The welding plate disassembly mechanism 400 is used to detachably connect the welding plate 500 to the support plate 600. The positioning mechanism 300 is used to temporarily clamp the steel panel 700 onto the support plate 600.

[0029] To facilitate the movement and positioning of the support, the four corners of the base 100 are fastened to the heavy-duty casters 120 by high-strength bolts. The heavy-duty casters 120 are made of polyurethane wheel surface, have built-in double ball bearings, and are equipped with a brake locking function. When the brake is locked in a stationary state, there is no displacement deviation. Two circular fixing holes 110 are evenly opened on the base 100 for double locking with the expansion bolts and the ground foundation to ensure the stability of the support during construction.

[0030] The height adjustment mechanism 200 includes a threaded sleeve 210, an adjusting screw 230, a guide sleeve 220, an indicator component 250, and a guide rod 240. The threaded sleeve 210 and the guide sleeve 220 are both vertically fixed to the upper surface of the base 100 by full welding. The threaded sleeve 210 is located at the center of the base 100, and the guide sleeves 220 are symmetrically arranged on both sides of the threaded sleeve 210. The center line connecting the three forms an isosceles triangle, which improves the stability of the support. The adjusting screw 230 is located at the bottom of the support plate 600 and is threadedly connected to the threaded sleeve 210. The guide rod 240 is located at the bottom of the support plate 600 and is slidably connected to the guide sleeve 220. The steel panel 700 is set on the support plate 600. In order to facilitate the rotation of the adjusting screw 230, a polygonal knob 260 is fixedly installed on the upper outer circumference of the adjusting screw 230. The indicator component is located at the bottom of the adjusting screw 230, which makes it easy for the operator to obtain height information.

[0031] Reference Figure 2 and Figure 3 The indicating component 250 includes a circular block 253 and an axial indicating rod 251. The circular block 253 is a solid carbon steel cylinder, which is rotatably connected to the bottom of the adjusting screw 230 via a deep groove ball bearing and slides inside the threaded sleeve 210. The axial indicating rod 251 is a stainless steel rod, which is vertically fixed to the outer circumference of the circular block 253 by welding. The inner wall of the threaded sleeve 210 is provided with a rectangular axial clearance hole 252 for the axial indicating rod 251 to slide, corresponding to the position of the axial indicating rod 251. The outer circumference of the threaded sleeve 210 is engraved with height scale lines distributed along its length. The axial indicating rod 251 penetrates the cylinder wall of the threaded sleeve 210. To facilitate reading, the top of the axial indicating rod 251 is provided with a red fluorescent scale indicator that matches the height scale lines.

[0032] Specifically, when adjusting the height of the support plate 600, the operator adjusts the adjusting screw 230 by placing the wrench opening against the side of the polygonal knob 260, applying torque to rotate the adjusting screw 230, thus driving the support plate 600 to rise and fall vertically. During this process, the guide rod 240 slides synchronously along the guide sleeve 220, restricting the rotational freedom of the support plate 600 and ensuring that the support plate 600 remains horizontal during rise and fall. The threaded transmission structure offers high adjustment precision, enabling fine-tuning of the support plate 600's height to meet the requirements of the steel panel 70. The precise elevation requirements for installation are met; the cooperative structure between the guide rod 240 and the guide sleeve 220 effectively prevents the support plate 600 from tilting or shifting during the lifting process. When the adjusting screw 230 rotates and rises, it also drives the round block 253 to rise and fall synchronously. The axial indicator rod 251 moves vertically along the axial clearance hole 252 of the threaded sleeve 210 with the round block 253. The operator can read the height adjustment amount of the support plate 600 in real time by observing the corresponding position of the scale indicator mark at the top of the axial indicator rod 251 and the height scale line on the outer circumference of the threaded sleeve 210.

[0033] The positioning mechanism 300 is used to temporarily clamp the steel panel 700 onto the support plate 600. The positioning mechanism 300 includes a support rod 310, a first threaded rod 330, an auxiliary clamping assembly 340, and a positioning block 320. The support rod 310 is located on the edge of the support plate 600 away from the steel panel. The support rod 310 is L-shaped, and its top is welded with a nut 410 seat with internal threads. The first threaded rod 330 is threadedly connected to the support rod 310. The positioning block 320 is fixedly disposed on the bottom end face of the first threaded rod 330, and the steel panel 700 corresponds to the positioning block 320. Positioning holes are provided at the location. In order to better realize the position adjustment of the steel panel 700, the positioning block 320 is conical in shape. The cross-sectional area of ​​the end near the steel panel 700 is larger than the cross-sectional area of ​​the end away from the steel panel 700. The diameter of the positioning hole on the steel panel 700 is larger than the minimum cross-sectional area of ​​the positioning block 320. The auxiliary pressing component 340 includes a fixing ring 341 and a pressing pad 342. The fixing ring 341 is located on the upper part of the positioning block 320. The pressing pad 342 is a silicone pad, which is fixed to the bottom of the fixing ring 341 by a vulcanization process. It has a honeycomb buffer structure inside.

[0034] Specifically, when installing the steel panel 700, the four corners of the steel panel 700 are first placed stably on the support plates 600 of the four adjustable welded brackets. The four support plates 600 correspond one-to-one with the four corners of the support plate 600. The operator rotates the first threaded rod 330, and by utilizing the threaded engagement between the first threaded rod 330 and the support rod 310, the first threaded rod 330 moves downward along the axial direction of the support rod 310. This causes the bottom positioning block 320 to gradually penetrate into the positioning hole on the steel panel 700. The fixing ring 341 moves downward synchronously with the positioning block 320. The bottom pressure pad 342 first comes into contact with the surface of the steel panel 700. As the first threaded rod 330 continues to tighten, the pressure pad 342 is compressed and undergoes elastic deformation, forming a secondary buffering and pressing effect. The pressure pad 342 is made of elastic materials such as rubber and silicone, which can prevent the positioning block 320 from directly and rigidly contacting the steel panel 700, effectively preventing the surface of the steel panel 700 from being scratched, and realizing the positioning and temporary fixation of the steel panel 700.

[0035] The welding plate disassembly mechanism 400 includes two welding plates 500, a second threaded rod 420, and a nut 410. The support plate 600 and the steel panel 700 have two corresponding limiting grooves on their respective sides that match the welding plates 500. The two welding plates 500 are respectively set in the limiting grooves. The second threaded rod 420 is set at the bottom of the welding plate 500 and passes through the support plate 600. The nut 410 is threadedly connected to the second threaded rod 420.

[0036] Specifically, after the steel panel 700 is temporarily fixed, the welding plate 500 is attached to the edge of the steel panel 700 as a welding transition part to assist in completing the welding operation. After welding is completed, concrete needs to be poured onto the steel panel 700. After the concrete solidifies, the weld points need to be cut to facilitate the separation of the support plate 600 from the steel panel 700 for subsequent use. Since there are residues after the weld points are cut, the operator rotates and unscrews the nut 410 to remove the welding plate 500 from the support plate 600, which facilitates the operator to clean up the weld residues and avoids the weld residues affecting the next welding effect.

[0037] The implementation principle of this application embodiment is as follows: Unlock the brake of the heavy-duty universal wheel 120 of the base 100, push the four sets of brackets to the preset positions at the four corners of the steel panel 700, step on the brake and insert expansion bolts through the fixing holes 110 for double locking; use a wrench to rotate the polygonal knob 260 on the adjusting screw 230 to adjust, and use the scale of the indicating component 250 to simultaneously adjust the four sets of support plates 600 to the design elevation and calibrate the level; lift the steel panel 700 and, with manual assistance, place its four corners on the support plate 600, align the positioning holes with the positioning blocks 320, rotate the first threaded rod 330 to drive the conical positioning block 320 into the positioning hole, until the pressing pad 342 of the auxiliary pressing component 340 adheres to the steel panel 700 and elastically deforms completely. Temporary fixation is achieved; welding is completed using welding plate 500 as a transition piece; steel panel 700 is further fixed. After welding is completed, the first threaded rod 330 is rotated to raise the positioning block 320. At this time, the temporary fixation is released, and the positioning hole is sealed. Concrete is poured in layers according to the design thickness and cured until solidified. After the concrete solidifies, the weld points are cut using an angle grinder to separate the welding plate 500 from the steel panel 700. After separation, the adjusting screw 230 is rotated to lower the welding bracket, the casters are unlocked to move the bracket away from the work area, the nut 410 is unscrewed to remove the welding plate 500, and the weld residue left after cutting the welding plate 500 is cleaned to avoid the weld residue affecting the installation quality of the steel panel 700 in the next installation.
