Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier construction, and specifically, to a high-precision positioning frame for pre-embedded steel bars of an assembled pier column. Background Technique

[0002] With the continuous development of bridge construction technology, in order to minimize the interference caused by urban bridge construction to the existing traffic, citizens' work and life, the assembled construction, which represents the development direction of factory-based, assembled, mechanized, green and rapid construction, has gradually become the first choice for urban bridge construction.

[0003] However, in the construction of assembled bridges, the connection between the pier column and the bearing platform and the capping beam mostly adopts grouting sleeve connection, which requires very high precision of the pre-embedded steel bars. Since the pre-embedded steel bars are pre-embedded synchronously on site during the binding of the bearing platform steel bars, the traditional pre-embedding method of the pre-embedded steel bars uses single-piece positioning pre-embedding, with low work efficiency and poor steel bar positioning accuracy, bringing great hidden dangers to the later installation.

The middle of the positioning frame body 100 is hollow. A plurality of positioning sleeves 110 are circumferentially arranged on the positioning frame body 100. A positioning hole for positioning the pre-embedded steel bar is provided in the positioning sleeve 110.

[0031] In this embodiment, the hollow design in the middle of the positioning frame body 100 facilitates operation and reduces weight.

[0032] Through the positioning sleeve 110 and the positioning holes in this embodiment, positioning sleeves 110 with different diameters can be customized according to the actual steel bar sizes, so as to achieve precise positioning of embedded steel bars with different diameters and improve the applicability.

[0033] In this embodiment, the positioning frame body 100 includes an upper frame 130 and a lower frame 140 that are correspondingly arranged up and down.

[0034] Through the upper frame 130 and the lower frame 140 that are correspondingly arranged up and down in this embodiment and are connected by the connecting part 150, the overall strength and stability of the positioning frame body 100 are increased.

[0035] In this embodiment, a profiled steel positioning frame 200 is provided on the outer side wall of the positioning frame body 100. The profiled steel positioning frame 200 includes a first mounting plate 210 and a second mounting plate 220. On the left and right sides of the first mounting plate 210 and the second mounting plate 220, there are first reinforcing plates 230 arranged perpendicular to the first mounting plate 210 and second reinforcing plates 240 arranged obliquely to the first mounting plate 210. The first mounting plate 210, the second mounting plate 220, the first reinforcing plates 230 and the second reinforcing plates 240 together form the profiled steel positioning frame 200.

[0036] Through the setting of the profiled steel positioning frame 200 in this embodiment, the positioning frame body 100 can be accurately positioned. The settings of the first mounting plate 210, the second mounting plate 220, the first reinforcing plates 230 and the second reinforcing plates 240 enable the whole to bear greater loads and resist stronger external forces, which helps to enhance the structural strength and further fix the positioning frame body 100.

[0037] In this embodiment, the positioning frame body 100 is clamped in the middle of the profiled steel positioning frame 200 to form a frame structure. The first mounting plate 210 and the second mounting plate 220 are used for fixed cooperation with the mounting frame body, and the first reinforcing plates 230 and the second reinforcing plates 240 further fix the positioning frame body 100.

[0038] Through the clamping setting of the mounting frame body 100 and the profiled steel positioning frame 200 in this embodiment, the installation process is simplified, so that the positioning frame body 100 can be quickly disassembled and reinstalled when needed, improving the construction efficiency. The cooperation setting of the positioning frame body 100 with the mounting plates and the reinforcing plates reduces the loosening or displacement of the positioning frame body 100 caused by vibration or external forces.

[0039] In this embodiment, the connecting portion 150 includes a web 151 for connecting the upper frame 130 and the lower frame 140. Stiffening plates 152 are vertically arranged along the web 151 on both side walls of the web 151 and are circumferentially distributed. The stiffening plates 152 are used to support the upper frame 130 and the lower frame 140.

[0040] Through the design of the web 151 and the stiffening plates 152 in this embodiment, additional support and stability are provided, making the positioning frame body 100 more stable when bearing heavy loads, and helping to reduce deformation or damage caused by long-term use or environmental factors.

[0041] In this embodiment, the positioning sleeve 110 is located on one side of the web 151 away from the middle of the positioning frame body 100. One end of the positioning sleeve 110 is connected to the lower frame 140, and the other end of the positioning sleeve 110 extends out of the upper frame 130 along the length direction of the positioning sleeve 110.

[0042] Due to the position of the positioning sleeve 110 in this embodiment, it is more stable when bearing the acting force from the embedded steel bars, reducing deformation and damage caused by stress transfer, and helping to maintain the structural stability of the mounting frame body 100.

[0043] In this embodiment, at the end of the side wall where the positioning sleeve 110 at the four corners extends out of the upper frame 130, a positioning joint 111 perpendicular to the positioning sleeve 110 is provided, and a positioning pin 120 that can extend into the positioning sleeve 110 is threadedly connected to the positioning joint 111.

[0044] Through the setting of the positioning joint and the positioning pin in this embodiment, when the steel bars are inserted into the positioning sleeve, the embedded steel bars can be fixed, which helps to improve the overall stability of the embedded steel bars and better position the embedded steel bars, reducing the displacement of the embedded steel bars caused by movement or vibration.

[0045] In this embodiment, lifting points 160 are provided between the positioning sleeves 110 at the four corners and the nearest positioning sleeve 110. The lifting points 160 are located at one end of the upper frame 130 away from the lower frame 140. The lifting points 160 are perpendicular to the positioning pins 120, and a through hole 161 is provided in the middle of the lifting points 160.

[0046] Through the setting of the lifting points and the through holes in this embodiment, the positioning frame body can be moved well, facilitating the overall handling, installation, disassembly and positioning of the positioning frame main body on the construction site, and increasing the convenience of construction.

[0047] In this embodiment, the diameter of the positioning hole is larger than the outer diameter of the embedded steel bar.

[0048] In this embodiment, the diameter of the positioning hole is larger than the outer diameter of the embedded steel bar, ensuring that the steel bar can be easily inserted and fixed, which helps to reduce the friction and resistance generated when inserting the embedded steel bar and extends the service life of the positioning sleeve 110.

[0049] When this embodiment is in use, according to the specific requirements of the construction site and the design dimensions of the pier column, a steel shape positioning frame 200 and a positioning frame body 100 of appropriate sizes are customized to ensure that the size of the steel shape positioning frame 200 can meet the support and fixing requirements for the positioning frame body 100. Prepare the required positioning sleeves 110, and customize the positioning sleeves 110 with different diameter positioning holes according to the actual size of the embedded steel bar to ensure the precise positioning of the steel bar; according to the size of the positioning frame body 100, initially determine the overlapping position of the bearing platform formwork and the support. Use a truck crane to hoist the positioning frame body 100 onto the bearing platform formwork through the through hole 161 in the middle of the lifting point 160, and manually cooperate with the truck crane to slowly move the positioning frame body 100 to the designed position to ensure the accurate contact position between the steel shape positioning frame 200 and the positioning frame body 100. Perform spot welding at the contact position to fix the positioning frame body 100, insert each embedded steel bar of the bearing platform into the steel bar positioning sleeve 110 one by one, and uniformly cut the top of the steel bars using a sawing machine so that the top of the steel bars is flush with the steel bar positioning sleeve 110. Then, screw the threaded positioning pins 120 on the positioning sleeves 110 at the four corners into the inside of the positioning sleeves 110 through the positioning joints 111 for fastening, so that the embedded steel bars and the steel bar positioning frame body 100 become a non-sliding integral body. Then, perform the pouring of concrete. After the strength reaches the requirements, the positioning frame body 100 and the steel shape positioning frame 200 are removed and moved away as a whole for repeated use.

[0050] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0051] In summary, the above are only the preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the patent of the present utility model.
