Description
Technical Field
[0001] The utility model belongs to the technical field of bridge construction equipment, and in particular relates to a prefabricated wedge block shaping die. Background Art
[0002] With the rapid development of highway construction, demand for prefabricated small box girders or T-beams is growing, and factory-based assembly line production is gradually increasing in popularity. To meet route requirements for drainage, turning, and climbing, small box girders or T-beams typically have transverse and longitudinal slopes at their tops and bottoms. When the turning angle is large, the beam ends also have diagonal angles. The wedges are located at the bottom of each end of the box girder, and they have both transverse and longitudinal slopes relative to the beam bottom.
[0003] To facilitate later beam erection, small box beams or T-beams are prefabricated with bottom wedges at the desired slope. During formwork commissioning, the wedges must be adjusted for both horizontal and vertical slopes. This is affected by the intersecting end faces, causing variations in the measurement datum. This makes conversion and measurement difficult and requires a high level of expertise. Horizontal and vertical slopes are typically around ±5%. Even small errors in the bottom beam slope during beam erection can be reflected back to the top beam, resulting in significant misalignment.
[0004] At present, the slope of the bottom wedge of a small box beam or T-beam is mainly adjusted manually. Multiple screws are installed at the bottom of the wedge. The height of the screws is manually adjusted and measured to see if they are in place. Multiple measurements and repeated adjustments are often required to ensure they are in place. In addition, due to the limitations of the professional quality of the staff, the actual error is large, and it is easy to make mistakes or make a reverse slope. Utility Model Content

[0027] like Figures 1 to 3 As shown, the prefabricated wedge block forming mold of the embodiment of the present application includes a base 10 and a universal rotating structure 40. The base 10 is provided with a forming groove 101, and a pad 20 is provided in the forming groove 101. The pad 20 is used to form the longitudinal and transverse slopes of the prefabricated wedge block; the universal rotating structure 40 is arranged at the center position of the pad 20, and the universal rotating structure 40 is respectively connected to the bottom plate 102 of the forming groove 101 and the pad 20. The base 10 is provided with a telescopic component 30 that abuts the bottom of the pad 20. The telescopic component 30 is spaced apart on the first side 201 of the pad 20 to cooperate with the universal rotating structure 40 to adjust the longitudinal and transverse slopes of the pad 20.
[0028] Specifically, in this embodiment, since the height of the center position of the pad 20 corresponding to the precast wedge block forming mold on the beam body is fixed, the center position of the pad 20 is used as a positioning reference to adjust the slope of the pad 20 to form the longitudinal and transverse slopes of the precast wedge block. The pad slope adjustment only needs to be adjusted by adjusting the telescopic assembly on one side of the pad 20. Specifically, in this embodiment, the telescopic assembly 30 can be an automatic telescopic assembly. The automatic telescopic assembly can use an automatic telescopic rod, an electric push rod, etc. in the existing technology to implement automatic slope adjustment of the pad 20. It can automatically calculate the lifting height based on the transverse slope, longitudinal slope, and oblique angle requirements of the precast wedge block, thereby adjusting the required slope of the pad 20. No further details are given here.
[0029] Therefore, the prefabricated wedge block forming mold provided in the embodiment of the present application adopts a universal rotating structure 40 set at the center position of the pad 20, and a telescopic device 30 is set at intervals on one side of the pad 20. It can fully utilize the fine-tuning and positioning functions of the universal rotating structure 40 to work in coordination with the telescopic component 30, and adjust the height of the pad 20 at different positions according to the longitudinal slope and transverse slope data required by the prefabricated wedge block so that the longitudinal and transverse slopes of the pad 20 match the longitudinal and transverse slopes of the prefabricated wedge block. Compared with the existing technology, the slope adjustment operation is simpler and more convenient, and the adjustment accuracy is high, which solves the problems of difficult and large error in slope adjustment during wedge block prefabrication, easy error or reverse slope, thereby improving the efficiency of the production line. In addition, in the slope adjustment process, the fine-tuning effect of the universal rotating structure can be fully utilized, making the structure simpler, more compact, stable and reliable.
[0030] like Figure 4 As shown, in one embodiment, the universal rotation structure 40 includes a ball head 401, a positioning shaft 402, and a stopper 403; wherein the ball head 401 and the positioning shaft 402 are connected; a stopper slot 204 is provided at the bottom of the base plate 20, and the ball head 401 is rotatably disposed within the stopper slot 204; the positioning shaft 402 is fixedly connected to the base plate 102 via a fastener 407 such as a lock nut, and the stopper 403 is nested at the bottom of the ball head 401 and fixedly connected to the base plate 20 via a fastener 407 such as a lock nut. Specifically, directly using the stopper slot 204 and the ball head 401 to achieve an articulated connection, the structure is simple and compact, the operation process is stable and reliable, and it is easy to manufacture. Specifically, the stopper slot 204 is a square recessed groove, which makes the installation and positioning of the ball head 401 and the stopper slot 204 extremely simple and convenient.
[0031] In one embodiment, the universal rotation structure 40 further includes a limiting structure 404 disposed between the ball head 401 and the positioning shaft 402. The bottom surface of the limiting structure 404 abuts against the base plate 102 to limit the distance between the connection point between the backing plate 20 and the ball head 401 and the base plate 102. By further providing the limiting structure 404 to limit the distance between the connection point between the backing plate 20 and the ball head 401 and the base plate 102, the universal rotation structure 40 can be ensured to be more stable and reliable during the operation of the coordinated telescopic assembly 30.
[0032] In one embodiment, the limiting structure 404 is a limiting boss, and the top of the limiting boss is provided with a chamfered structure 405. Specifically, the use of a limiting boss as the limiting structure 404 is simple in structure and easy to manufacture. Moreover, the provision of the chamfered structure 405 can effectively prevent interference between the limiting structure 404 and other parts, and avoid stress concentration at the connection with the transition portion 406.
[0033] In one embodiment, a transition portion 406 is provided between the ball head 401 and the limiting boss. The limiting member 403 is a plate-like structure nested between the bottom of the ball head 401 and the transition portion 406. The provision of the transition portion 406 not only effectively secures the plate-like limiting member 403 but also effectively adjusts the distance between the ball head 401 and the limiting boss to accommodate the relative positional constraints between the backing plate 20 and the base plate 102. Furthermore, to ensure a good match between the contact area between the ball head 401 and the limiting member 403, a circular arc groove structure that matches the spherical surface structure of the bottom of the ball head 401 can be provided on the limiting member 403 where it contacts the bottom of the ball head 401.
[0034] In one embodiment, the telescopic assembly 30 includes two groups, and the line connecting the universal rotation structure 40 and the two groups of telescopic assemblies 30 forms a triangle. Specifically, the triangular arrangement of the universal rotation structure 40 and the two groups of telescopic assemblies 30 can greatly improve the stability and reliability of the slope adjustment process of the pad 20.
[0035] In one embodiment, support assemblies 50 are provided at intervals on the base 10 to abut the bottom of the pad 20. The support assemblies 50 are used to support the pad 20 after the universal rotation structure 40 cooperates with the telescopic assembly 30 to adjust the longitudinal and transverse slopes of the pad 20. Specifically, after the telescopic assembly 30 lifts the pad 20 to a preset slope, the support assembly 50 is used to support the pad 20, thereby achieving the slope adjustment of the prefabricated wedge. In one embodiment, multiple groups of support assemblies 50 are symmetrically arranged at intervals on the second side 202 and the third side 203 adjacent to the first side 201. The arrangement of the above-mentioned support assemblies 50 can be combined with the universal rotation structure 40 to evenly distribute the supporting force on the bottom of the pad 20, thereby avoiding uneven support force on the pad 20 and affecting the accuracy of the slope.
[0036] In one embodiment, the support assembly 50 includes an adjusting screw 501 and an adjusting nut 502. The adjusting screw 501 is passed through the base plate 102, and the adjusting nut 502 is used to fix the adjusting screw 501 to the base plate 102. The adjusting screw 501 improves the support function and prevents the actuator of the telescopic assembly, such as the automatic telescopic rod, from being damaged by the weight of the concrete beam above. When the actuator is adjusted to an angle, the adjusting screw 501 is used to adjust the height vertically to fix the base plate 20. After detection, the telescopic assembly, such as the actuator of the automatic telescopic rod, is retracted to avoid damage. In addition, because the universal rotation structure 40 can limit the base plate 20, it can prevent the base plate 20 from being lifted up when the adjusting screw 501 is turned, affecting the accuracy of the slope.
[0037] In one embodiment, the end of the adjusting screw 501 that contacts the backing plate 101 is a spherical structure. By setting the top of the adjusting screw 501 as a spherical structure, damage to the backing plate 20 during the supporting process can be avoided.
[0038] According to the above embodiments, it can be seen that the prefabricated wedge block forming mold involved in the present application has a simple and convenient slope adjustment operation and high adjustment accuracy, which solves the problems of difficulty in adjusting the slope of the wedge block during prefabrication, large errors, easy mistakes or reverse slope, and has a simple and compact structure, stable and reliable.

Any changes or substitutions that can be easily made by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the appended claims.
