Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, and more specifically, to a fixture for fixing embedded parts of precast concrete components. Background Technology

[0002] In the production of precast concrete components, the precise positioning of embedded parts directly affects the structural performance of the components. Traditional fixing fixtures mostly rely on single-point locking structures to position precast components, which have problems such as insufficient vibration resistance and low degree of adjustment. During the pouring process, vibration can easily cause embedded parts to shift, affecting product quality. In addition, existing fixing fixtures are complex in structure and time-consuming to assemble and disassemble, which is not conducive to improving production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for fixing embedded parts of precast concrete components. It has a simple structure and can quickly and stably position embedded parts, effectively improving product quality and production efficiency.

[0004] A fixture for fixing embedded parts of precast concrete components includes a mold, a crossbar mounted on the mold, and at least one positioning component slidably connected to the crossbar. The positioning component includes a sleeve, two fixing components, and a positioning element. The sleeve is fitted around the outer periphery of the crossbar. The sleeve includes a first surface at the upper end and a second surface perpendicular to the first surface. The two fixing components are respectively disposed on the first surface and the second surface. The positioning element is fixedly connected to the sleeve.

[0005] In the above technical solution, the positioning component is freely adjustable in the horizontal direction through the sliding connection between the sleeve and the crossbar, meeting the installation requirements of different embedded parts positions and offering flexibility and convenience. Two sets of fixing components act on the vertical and horizontal planes of the sleeve respectively, forming a bidirectional lock that effectively prevents sleeve displacement during pouring and ensures the accuracy of the embedded part position. The fixed connection between the positioning component and the sleeve simplifies the tooling structure and improves overall stability.

[0006] Furthermore, the fixing component includes a fixing nut and a fixing bolt. The fixing nut is fixedly connected to the sleeve, the sleeve has a through hole corresponding to the fixing nut, and the fixing bolt is threadedly connected to the fixing nut and passes through the through hole.

[0007] In the above technical solution, a threaded bolt and nut are used as the locking mechanism, which allows for rapid adjustment of tightness through rotation and maintains a constant clamping force by utilizing the self-locking property of the threads. The through-hole structure allows the bolt end to directly abut against the surface of the crossbar, preventing accidental slippage caused by vibration.

[0008] Furthermore, the sleeve includes a third surface located at its lower end, to which the positioning element is welded.

[0009] In the above technical solution, the positioning component is welded to the bottom of the sleeve, which on the one hand ensures the stability of the connection, and on the other hand facilitates the positioning component to extend into the interior of the cast structure to achieve pre-embedding.

[0010] Furthermore, the sleeve includes a fourth surface opposite to the second surface, and the positioning element is welded to the fourth surface.

[0011] In the above technical solution, the positioning component is welded to the side surface of the sleeve, which can meet the pre-embedding requirements of horizontal or inclined angles, and the welding structure can ensure the stability of the overall structure.

[0012] Furthermore, the mold includes two end molds arranged opposite each other and two side molds arranged opposite each other, with the two end molds and the two side molds forming a rectangle.

[0013] In the above technical solution, the mold adopts a rectangular frame structure, and the assembly and disassembly efficiency is improved by modularly assembling the end mold and the side mold.

[0014] Furthermore, the two ends of the crossbar are respectively connected to the two side molds.

[0015] In the above technical solution, the two ends of the crossbar are connected to the side mold, which simplifies the installation and positioning process of the crossbar and facilitates quick adjustment of the tooling layout.

[0016] Furthermore, the upper surface of the side mold is provided with several sets of positioning holes, and the two ends of the crossbar are provided with positioning plates. The positioning plates are provided with threaded positioning elements, and the threaded positioning elements can select one set of positioning holes to connect with the side mold.

[0017] In the above technical solution, the cooperation of multiple sets of positioning holes and threaded positioning parts enables flexible adjustment of the crossbar position, which can be adapted to the production needs of pre-embedded parts in different positions.

[0018] Furthermore, there are at least two crossbars, and the at least two crossbars are arranged along the length direction of the side mold.

[0019] In the above technical solution, multiple crossbars can simultaneously perform positioning operations for multiple sets of embedded parts, thereby improving production efficiency.

[0020] Compared with existing technologies, the advantages of this invention are: the sliding connection between the sleeve and the crossbar allows for free adjustment of the positioning component in the horizontal direction, meeting the installation requirements of different embedded parts positions, and offering flexibility and convenience. Two sets of fixing components act on the vertical and horizontal planes of the sleeve respectively, forming a bidirectional lock, effectively preventing sleeve displacement during pouring and ensuring the accuracy of the embedded part position. The fixed connection between the positioning component and the sleeve simplifies the tooling structure and improves overall stability. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] Please refer to Figures 1 to 6 In a preferred embodiment, the precast concrete component fixing fixture of this utility model mainly includes a mold 1, a crossbar 2, and at least one positioning component 3. The crossbar 2 is mounted on the mold 1, and the positioning component 3 is slidably connected to the crossbar 2. The positioning component 3 includes a sleeve 31, two fixing components 32, and a positioning element 33. The sleeve 31 is fitted around the outer periphery of the crossbar 2 and includes a first surface at its upper end and a second surface perpendicular to the first surface. The two fixing components 32 are respectively disposed on the first and second surfaces, and the positioning element 33 is fixedly connected to the sleeve 31.

[0032] For example, the crossbar 2 is a tubular shape with a square cross-section. A sleeve 31 is fitted around the outer periphery of the crossbar 2, and the shape of the sleeve 31 matches the circumferential shape of the crossbar 2. The sleeve 31 includes a first surface at the upper end, a third surface at the lower end parallel to the first surface, and a second and fourth surface perpendicularly connected between the first and third surfaces. The sleeve 31 can slide along the extension direction of the crossbar 2, thereby adjusting the position of the positioning member 33. The positioning member 33 is used to connect embedded parts; in specific implementations, the positioning member 33 can utilize an existing embedded part connection and positioning structure.

[0033] As can be seen from the above technical solution, the sliding connection between the sleeve 31 and the crossbar 2 enables the positioning component 3 to be freely adjustable in the horizontal direction, meeting the installation requirements of different embedded parts positions, and is flexible and convenient to use. Two sets of fixing components 32 act on the vertical and horizontal planes of the sleeve 31 respectively, forming a bidirectional lock, effectively preventing displacement of the sleeve 31 during pouring and ensuring the accuracy of the embedded part position. The positioning component 33 is fixedly connected to the sleeve 31, simplifying the tooling structure and improving overall stability.

[0034] The fixing component 32 includes a fixing nut 321 and a fixing bolt 322. The fixing nut 321 is fixedly connected to the sleeve 31, and the sleeve 31 has a through hole corresponding to the fixing nut 321. The fixing bolt 322 is threadedly connected to the fixing nut 321 and passes through the through hole. The threaded fixing bolt 322 and nut serve as a locking mechanism, which allows for quick adjustment of tightness through rotation and maintains a constant clamping force using the self-locking property of the thread. The through hole structure allows the bolt end to directly abut against the surface of the crossbar 2, preventing accidental slippage caused by vibration.

[0035] Please refer to Figure 2 and Figure 3 In the first embodiment of this utility model, the sleeve 31 includes a third surface located at its lower end, and a positioning member 33 is welded to the third surface. Welding the positioning member 33 to the bottom of the sleeve 31 ensures the stability of the connection and facilitates the positioning member 33 to extend into the interior of the cast structure for pre-embedding.

[0036] Please refer to Figure 4 and Figure 5 In the second embodiment of this utility model, the sleeve 31 includes a fourth surface opposite to the second surface, and the positioning member 33 is welded to the fourth surface. The positioning member 33 is welded to the lateral surface of the sleeve 31, which can meet the pre-embedding requirements of horizontal or inclined angles, and the welding structure can ensure the stability of the overall structure.

[0037] Please refer to Figure 1 and Figure 6 The mold 1 includes two end molds 11 arranged opposite each other and two side molds 12 arranged opposite each other, forming a rectangle. The mold 1 adopts a rectangular frame structure, and the modular assembly of the end molds 11 and the side molds 12 improves the efficiency of assembly and disassembly.

[0038] The two ends of the crossbar 2 are respectively connected to the two side molds 12. By connecting the two ends of the crossbar 2 to the side molds 12, the installation and positioning process of the crossbar 2 is simplified, and the tooling layout can be quickly adjusted.

[0039] The upper surface of the side mold 12 has several sets of positioning holes 121. The two ends of the crossbar 2 are provided with positioning plates 21, and the positioning plates 21 are provided with threaded positioning parts 22. The threaded positioning parts 22 can select one set of positioning holes 121 to connect with the side mold 12. The cooperation of multiple sets of positioning holes 121 and threaded positioning parts 22 realizes the flexible adjustment of the position of the crossbar 2, which can adapt to the production needs of different pre-embedded positions.

[0040] In the above embodiment, there are at least two crossbars 2, and at least two crossbars 2 are arranged along the length direction of the side mold 12. Multiple crossbars 2 enable simultaneous positioning of multiple sets of embedded parts, thereby improving production efficiency.
