Description

Technical Field

[0001] This application relates to the technical field of pads, and in particular to an adjustable steel pad. Background Technology

[0002] In cast-in-place concrete construction, the positioning accuracy of reinforcing bars directly affects the structural bearing capacity. Current specifications require that the thickness error of the reinforcing bar protective layer be controlled within ±5mm, but on construction sites, factors such as formwork deformation and foundation settlement often lead to a deviation of 10 to 30mm between the design elevation and the actual elevation.

[0003] Traditional solutions often employ precast concrete blocks or temporary welded steel supports. The former cannot adapt to dynamic error adjustments, while the latter suffers from corrosion, contamination, and high labor intensity. In recent years, some projects have attempted to use adjustable aluminum alloy supports, but their cost is 8-10 times that of ordinary blocks, making large-scale adoption difficult.

[0004] Regarding the aforementioned technologies, the invention and existing pads have the following disadvantages: 1) The fixed size of traditional concrete blocks leads to poor construction adaptability; 2) Exposed rust on steel components causing surface contamination of concrete; 3) Customized adjustment devices are more expensive. Utility Model Content

[0005] To address the problems of poor adaptability and susceptibility to external corrosion of traditional pads, this application provides a steel adjustable pad.

[0006] The steel adjustable pad provided in this application adopts the following technical solution: An adjustable steel pad includes a pad base, which includes a main base plate and a positioning bracket. The positioning bracket is vertically installed on the upper surface of the main base plate and is inserted and fixed to the main base plate. A double-headed screw frame is also installed on the main base plate and is fixedly connected to the main base plate. Two sets of cooperating locking nuts are also installed on the double-headed screw frame. A sliding lock is installed on the lower surface of the main base plate to lock the two sets of locking nuts. The sliding lock is slidably connected to the main base plate.

[0007] By adopting the above technical solution, the pad seat is designed as a structure in which the main seat plate and the positioning bracket cooperate. The positioning bracket is then inserted and fixed to the main seat plate, facilitating the installation and disassembly of the positioning bracket, improving work efficiency, and allowing for flexible replacement of different positioning brackets when locking rebars of different diameters, thus enhancing the equipment's applicability. The double-headed screw frame is fixedly connected to the main seat plate and, with the assistance of two sets of locking nuts, enables precise height adjustment. The sliding lock is slidably connected to the main seat plate. When not in use, the two sets of locking nuts can be rotated to a parallel position, allowing the sliding lock to be supported between the two sets of locking nuts, locking them in place to prevent loosening and ensuring stability after adjustment.

[0008] Optionally, the upper end face of the main base plate is provided with a blind insertion hole for mounting the positioning bracket, and the upper end face of the main base plate is also provided with a positioning through hole for inserting the double-headed screw bracket. The lower end face of the main base plate is also provided with a limiting groove for sliding installation of the sliding lock component.

[0009] By adopting the above technical solution, the blind insertion holes and positioning through holes opened on the main plate provide accurate positioning for the installation of the positioning bracket and the double-headed screw bracket, ensuring the accuracy and stability of the installation of each component. The setting of the limiting slide groove provides guidance for the sliding of the sliding lock, enabling the sliding lock to slide smoothly and effectively lock the locking nut.

[0010] Optionally, the positioning support includes a U-shaped block and a plug-in rod corresponding to the plug-in blind hole. The plug-in rod is installed on both sides of the lower end face of the U-shaped block, and the plug-in rod is integrally formed with the U-shaped block.

[0011] By adopting the above technical solution, the positioning bracket uses a U-shaped base block and a plug-in rod integrally formed structure, which is not only simple in structure but also has high strength and stability. The U-shaped base block can better support the object that needs support, and the cooperation between the plug-in rod and the plug-in blind hole makes the installation of the positioning bracket more secure.

[0012] Optionally, the double-headed screw frame includes an arc-shaped pressure rod and a screw portion for installing a locking nut. The screw portion is symmetrically arranged at both ends of the arc-shaped pressure rod, and the screw portion and the arc-shaped pressure rod are integrally formed.

[0013] By adopting the above technical solution, the arc-shaped pressure rod and the screw section of the double-headed screw frame are integrally formed, ensuring the integrity and strength of the structure. The screw section is used to install the locking nut, and the height can be adjusted by rotating the locking nut. The arc-shaped pressure rod can better adapt to different usage scenarios and provide a more flexible adjustment method.

[0014] Optionally, an operating handle is installed on the upper end face of the arc-shaped pressure bar, and the operating handle is fixedly connected to the arc-shaped pressure bar.

[0015] By adopting the above technical solution, the design of the operating handle facilitates the operation of the double-ended screw head. When adjusting the height, the operator can more easily rotate the double-ended screw head by holding the operating handle, thus improving the ease of operation.

[0016] Optionally, the sliding lock includes a support block and a positioning slide plate slidably installed in the limiting slide groove. The positioning slide plate is installed on the upper end surface of the support block, and the positioning slide plate and the support block are integrally formed.

[0017] By adopting the above technical solution, the support block and positioning slide plate of the sliding lock are integrally formed, resulting in a compact structure and good stability. The positioning slide plate slides in the limiting groove, which can accurately lock the locking nut, while the support block provides the necessary support force for locking.

[0018] Optionally, a right-angle plate assembly is installed on the lower end face of the main seat plate. The right-angle plate assembly is fixedly connected to the main seat plate, and a support spring is also fixedly installed between the right-angle plate assembly and the support block.

[0019] By adopting the above technical solution, the right-angle plate assembly and the support spring provide elastic support for the sliding lock component. When the sliding lock component locks the locking nut, the support spring can provide cushioning to prevent rigid collision between the sliding lock component and the locking nut, while also ensuring the stability of the sliding lock component during the locking process.

[0020] Optionally, a plastic protective cap is fitted onto the lower end face of the screw section, and the plastic protective cap is detachably and fixedly connected to the screw section.

[0021] By adopting the above technical solution, the plastic protective cap protects the lower end face of the screw, preventing damage during use. The plastic protective cap is detachably and securely connected to the screw, facilitating replacement and maintenance.

[0022] In summary, this application offers at least one of the following beneficial technical effects: The steel adjustable pad of this application has a reasonable overall structural design, with tight fit between all components. Through the synergistic action of components such as the positioning bracket, double-headed screw frame, locking nut, and sliding lock, highly precise adjustment and reliable locking are achieved. Its installation and disassembly process is simple and convenient, improving work efficiency. Simultaneously, the structural design and protective measures of each component ensure the strength, stability, and service life of the pad, meeting various application needs in industrial production and construction.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an adjustable steel pad. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a steel adjustable pad includes a pad seat 1, which includes a main seat plate 11 and a positioning bracket 12. The positioning bracket 12 is vertically installed on the upper surface of the main seat plate 11 and is inserted and fixed to the main seat plate 11. A double-headed screw frame 2 is also installed on the main seat plate 11 and is fixedly connected to the main seat plate 11. Two sets of cooperating locking nuts 3 are also installed on the double-headed screw frame 2. A sliding lock 4 for locking the two sets of locking nuts 3 is installed on the lower surface of the main seat plate 11 and is slidably connected to the main seat plate 11. By designing the pad seat 1 into a structure in which the main seat plate 11 and the positioning bracket 12 cooperate, and by inserting and fixing the positioning bracket 12 to the main seat plate 11, the installation and disassembly of the positioning bracket 12 are facilitated, improving work efficiency. Furthermore, different positioning brackets 12 can be flexibly replaced when locking steel bars of different diameters, thus improving the applicability of the equipment. The double-headed screw bracket 2 is fixedly connected to the main base plate 11 and, together with two sets of locking nuts 3, allows for precise height adjustment. The sliding lock 4 is slidably connected to the main base plate 11. When not in use, the two sets of locking nuts 3 can be rotated to a parallel position, allowing the sliding lock 4 to be supported between the two sets of locking nuts 3. This locks the locking nuts 3, preventing them from loosening and ensuring stability after adjustment.

[0032] Reference Figure 4 and Figure 6 As shown, the upper end face of the main base plate 11 has a blind insertion hole for mounting the positioning bracket 12, and the upper end face of the main base plate 11 also has a positioning through hole 111 for inserting the double-headed screw bracket 2. The lower end face of the main base plate 11 also has a limiting groove 112 for sliding installation of the sliding lock component 4. The blind insertion hole and the positioning through hole 111 on the main base plate 11 provide accurate positioning for the installation of the positioning bracket 12 and the double-headed screw bracket 2, ensuring the accuracy and stability of the installation of each component. The limiting groove 112 provides guidance for the sliding of the sliding lock component 4, enabling the sliding lock component 4 to slide smoothly and effectively lock the locking nut 3. The positioning bracket 12 includes a U-shaped seat block 121 and a plug-in rod 122 corresponding to the blind insertion hole. The plug-in rod 122 is installed on both sides of the lower end face of the U-shaped seat block 121, and the plug-in rod 122 is integrally formed with the U-shaped seat block 121. The positioning bracket 12 adopts an integral structure of U-shaped seat block 121 and plug-in rod 122, which is not only simple in structure, but also has high strength and stability. The U-shaped seat block 121 can better support the object that needs to be supported, and the cooperation between the plug-in rod 122 and the plug-in blind hole makes the installation of the positioning bracket 12 more secure.

[0033] Reference Figure 5As shown, the double-headed screw frame 2 includes an arc-shaped pressure rod 21 and a screw section 22 for mounting the locking nut 3. The screw section 22 is symmetrically arranged at both ends of the arc-shaped pressure rod 21, and the screw section 22 and the arc-shaped pressure rod 21 are integrally formed. The integral formation of the arc-shaped pressure rod 21 and the screw section 22 of the double-headed screw frame 2 ensures the integrity and strength of the structure. The screw section 22 is used to mount the locking nut 3. The height can be adjusted by rotating the locking nut 3. The arc-shaped pressure rod 21 can better adapt to different usage scenarios and provide a more flexible adjustment method. An operating handle 211 is installed on the upper end face of the arc-shaped pressure rod 21, and the operating handle 211 is fixedly connected to the arc-shaped pressure rod 21. The setting of the operating handle 211 facilitates the operation of the double-headed screw frame 2 by the operator. When adjusting the height, the operator can hold the operating handle 211 to rotate the double-headed screw frame 2 more easily, improving the convenience of operation.

[0034] Reference Figure 2 and Figure 3 As shown, the sliding lock component 4 includes a support block 41 and a positioning slide plate 42 slidably installed in the limiting slide groove 112. The positioning slide plate 42 is installed on the upper end face of the support block 41, and the positioning slide plate 42 and the support block 41 are integrally formed. The support block 41 and the positioning slide plate 42 of the sliding lock component 4 are integrally formed, resulting in a compact structure and good stability. The positioning slide plate 42 slides in the limiting slide groove 112, which can accurately lock the locking nut 3, and the support block 41 provides the necessary support force for locking. A right-angle plate assembly 13 is installed on the lower end face of the main seat plate 11. The right-angle plate assembly 13 is fixedly connected to the main seat plate 11, and a support spring 131 is also fixedly installed between the right-angle plate assembly 13 and the support block 41. The right-angle plate assembly 13 and the support spring 131 provide elastic support for the sliding lock component 4. When the sliding lock 4 locks the locking nut 3, the support spring 131 provides cushioning to prevent rigid collisions between the sliding lock 4 and the locking nut 3, while also ensuring the stability of the sliding lock 4 during the locking process. A plastic protective cap 221 is fitted onto the lower end face of the screw portion 22, and the plastic protective cap 221 is detachably and fixedly connected to the screw portion 22. The plastic protective cap 221 protects the lower end face of the screw portion 22, preventing damage during use. The detachable and fixed connection between the plastic protective cap 221 and the screw portion 22 facilitates replacement and maintenance.

[0035] The implementation principle of the steel adjustable pad in this embodiment is as follows: During component installation, the main base plate 11 is preferably made of high-strength carbon steel, and its size is designed according to actual usage requirements. The U-shaped seat block 121 and the plug-in rod 122 of the positioning bracket 12 are manufactured using an integral molding process, and the material is also carbon steel. During installation, a suitable positioning bracket 12 is selected, and the plug-in rod 122 is inserted into the plug-in blind hole of the main base plate 11, ensuring that the positioning bracket 12 is vertically installed on the upper end face of the main base plate 11. Then, the screw part 22 of the double-headed screw bracket 2 is passed through the positioning through hole 111 on the main base plate 11, and then the locking nut 3 is installed to limit and lock the position. The locking nut 3 is a standard specification nut, made of carbon steel, and galvanized to improve rust resistance. After the edges of the two sets of locking nuts 3 are rotated to a parallel position, the support block 41 of the sliding lock 4 can be supported between the two sets of locking nuts 3 for locking. Finally, the plastic protective cap 221 is put on the locking nuts 3 for protection. The plastic protective cap 221 is made of soft plastic and is fitted onto the lower end face of the screw part 22 by an interference fit to achieve a detachable and fixed connection.

[0036] When height adjustment is required, the sliding lock 4 releases the locking nut 3, and then the locking nut 3 is rotated. The height is adjusted through the engagement of the screw 22 and the locking nut 3. Adjust to the appropriate height as needed. After height adjustment, the sliding lock 4 locks the two sets of locking nuts 3. The sliding lock 4 slides within the limiting groove 112, and the support spring 131 provides elastic support to ensure locking stability.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
