Description

Technical Field

[0001] The invention belongs to the technical field of bridge pier column formwork, and in particular relates to a variable radius chamfering formwork system for a circular solid bridge pier top cap. Background Art

[0002] During the construction of bridge pier caps, a circle of chamfers will generally be constructed around the pier caps. The chamfer design helps to disperse the stress concentration at the edge of the pier caps, making the force more uniform, avoiding structural damage due to stress concentration, and better optimizing the bridge pier structure.

[0003] In the existing bridge pier construction, the bridge pier top cap will directly set the chamfer template at the chamfered part and the top cap template as an integrated structure; the top cap steel bars are directly tied inside the template, which increases the difficulty of the top cap steel bar tying operation due to the small space inside the top cap template; if the top cap steel bars are tied and then hoisted into the top cap template, the existence of the chamfer template (the inlet cross-section size of the chamfer template position is small) will affect the hoisting operation of the top cap steel bars, making the installation of the top cap steel bars more difficult, reducing the safety factor and affecting the construction efficiency. In addition, since top caps of different diameters require chamfer templates of different sizes, it is necessary to make specific chamfer templates for top caps of specific sizes, which greatly increases the construction cost.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Invention content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixedly connected or detachably connected; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0033] According to the specific embodiments of the present invention, Figure 1-4 As shown, the present invention provides a variable radius chamfer template system for a circular solid bridge pier top cap, the template system comprising:

[0034] The chamfer template is used to independently form the chamfered part of the pier top cap. The chamfer template includes a fixed chamfer template 1 and a telescopic chamfer template 2. A plurality of guide rings 4 are arranged on the back of the fixed chamfer template 1. A part of the telescopic chamfer template 2 is guided and moved in at least one guide ring 4 so that the telescopic chamfer template 2 extends out of or retracts into the guide ring 4 on the back of the fixed chamfer template 1 to change the length of the entire chamfer template.

[0035] The fixing frame 3 surrounds the periphery of the chamfering template, and a pushing assembly 5 is movably arranged on the fixing frame 3, and the end of the pushing assembly 5 is hinged to the back side of the chamfering template.

[0036] In the chamfer formwork system, the chamfer formwork is independently arranged. First, after the top cap steel bar is installed on the top cap formwork, the chamfer formwork system can be installed on the top cap formwork, so that the chamfer formwork system will not affect the installation operation of the top cap steel bar, which is conducive to improving construction efficiency.

[0037] When it is necessary to apply the chamfer formwork system to top cap construction operations with different diameters, the telescopic chamfer formwork 2 can be extended from or retracted into the fixed chamfer formwork 1 to a set length. Since the unfolded shape of the chamfer formwork is a fan-shaped structure, after the telescopic chamfer formwork 2 is extended from or retracted into the fixed chamfer formwork 1, the telescopic chamfer formwork 2 and the fixed chamfer formwork 1 have a certain overlapping portion, thereby only changing the overall length of the chamfer formwork without changing the inclination angle of the chamfer formwork; when the length of the chamfer formwork is determined, adjust the pushing assembly 5 on the fixing frame 3 to adjust the spacing between the fixing frame 3 and the chamfer formwork, so that the chamfer formwork is bent to a curvature arc that matches the size of the top cap; that is, the chamfer formwork system can be adjusted to sizes of different radii, so that the chamfer formwork system can be applicable to top cap construction operations of different sizes, which not only greatly improves the applicability of the chamfer formwork system, but also can greatly reduce the construction cost of the bridge piers.

[0038] A hinge seat 51 is provided on the back of the chamfering template, one end of the push assembly 5 is hinged on the hinge seat 51, and the hinge axis of the push assembly 5 extends in the vertical direction.

[0039] In one embodiment of the present application, as the telescopic chamfer template 2 is extended and retracted relative to the fixed chamfer template 1, the size of the chamfer template will change, and the end of the pushing assembly 5 is hinged to the hinge seat 51 on the back of the chamfer template, so that when the chamfer template changes in size, the pushing assembly 5 can rotate relative to the chamfer template to adapt to the size change of the chamfer template, thereby avoiding the pushing assembly 5 from restricting the size change of the chamfer template.

[0040] In this embodiment, the articulated seat 51 can be set on the back of the fixed chamfering template 1, the telescopic chamfering template 2 and part of the guide ring 4, and the position and number of the articulated seat 51 correspond to the position and number of the pushing components 5; wherein, multiple pushing components 5 are distributed as evenly as possible on the fixed frame 3 so that the chamfering template receives a more uniform pushing force.

[0041] The push assembly 5 includes a slide block 55, and a slide groove is provided on the fixed frame 3, and the slide block 55 slides in the slide groove; the slide block 55 is cylindrical, and the axis of the cylindrical slide block 55 is perpendicular to the plane where the fixed frame 3 is located. In one embodiment of the present application, the slide block 55 in the push assembly 5 slides along the fixed frame 3, so that the position of the push assembly 5 relative to the fixed frame 3 can be adjusted. When the chamfering template is adjusted to different curvature radii, the push assembly 5 can apply pressure to the chamfering template at a suitable position.

[0042] In the present application, the slider 55 is set to be cylindrical so that the stud 53 can drive the slider 55 to rotate; thereby, in the process of adjusting the size of the chamfering template, the position of the push assembly 5 can be adaptively changed, so that the push assembly 5 will not limit the size adjustment process of the chamfering template, thereby better adapting to the size adjustment process of the chamfering template.

[0043] The push assembly 5 further includes an articulated rod 52, which is articulated on the articulated seat 51 of the chamfering template. In one embodiment of the present application, an independent articulated rod 52 is provided, which is more convenient for articulating with the articulated seat 51.

[0044] The push assembly 5 further includes a stud 53 , one end of which is threadedly connected to the hinge rod 52 , and the other end of which is threadedly connected to the slider 55 .

[0045] In one embodiment of the present application, the distance between the hinge rod 52 and the slider 55 is adjusted by rotating the stud 53. That is, when the chamfering template is set to different diameter sizes, the distance between the chamfering template and the fixing frame 3 is adjusted by adjusting the length of the stud 53 retracted in the hinge seat 51, so that the fixing frame 3 can better support the chamfering templates of different diameter sizes.

[0046] A long through hole is provided on the fixing frame 3 at the position corresponding to the stud 53, and the stud 53 moves in the long through hole. In one embodiment of the present application, a long through hole is provided in the fixing frame 3 at the position corresponding to the stud 53, so that the stud 53 can adjust the position relative to the fixing frame 3. When corresponding to chamfering templates of different diameters, the stud 53 can be moved to different positions in the fixing frame 3, so as to better support the chamfering template.

[0047] The slider 55 is provided with a threaded hole, in which a slider bolt 54 is threadedly connected; the fixing frame 3 is provided with a long through hole corresponding to the position of the slider bolt 54, for the slider bolt 54 to pass through the long through hole and then be threadedly connected to the slider 55. In one embodiment of the present application, after the slider 55 is moved into position, the slider bolt 54 is tightened to fix the slider 55 on the fixing frame 3, so that the push assembly 5 can support the chamfering template more stably.

[0048] At least one of the plurality of guide rings 4 is threadedly connected with a clamping bolt 7. After the position of the telescopic chamfer template 2 in the fixed chamfer template 1 is adjusted, the clamping bolt 7 is tightened to fix the telescopic chamfer template 2 relative to the fixed chamfer template 1. In one embodiment of the present application, the telescopic chamfer template 2 is pressed against the fixed chamfer template 1 by the clamping bolt 7, so that the telescopic chamfer template 2 is fixed relative to the fixed chamfer template 1, and the size of the chamfer template is adjusted.

[0049] A fixing rod 8 is provided at the bottom of the fixing frame 3, and the fixing rod 8 is used to be fixed in the top hat mold. In one embodiment of the present application, by providing the fixing rod 8 at the bottom of the fixing rod 8, a perforation can be provided at a corresponding position of the top hat mold for the fixing rod 8 to pass through, and then a nut is connected to the fixing rod 8 to fix the chamfer template system on the top hat mold.

[0050] A pair of lifting ears 6 are symmetrically arranged on the top surface of the fixing frame 3. In one embodiment of the present application, the entire chamfering formwork system can be hoisted by the lifting ears 6, which makes it easier to transport the chamfering formwork system.

[0051] When using the chamfer template system, first adjust the size of the chamfer template according to the size of the top hat to be constructed, retract the telescopic chamfer template 2 into or extend a part of the fixed chamfer template 1, and after the size adjustment of the chamfer template is completed, tighten the clamping bolt 7 to fix the telescopic chamfer template 2 relatively to the fixed chamfer template 1; in the process of adjusting the size of the chamfer template, loosen the slider bolt 54 so that the push assembly 5 can move relative to the fixing frame 3, so that the push assembly 5 can adapt to the different size changes of the chamfer template in time; then adjust the position of the slider 55 so that each push assembly 5 can push the chamfer template at a suitable position, and rotate and adjust the stud 53 to adjust the distance between the chamfer template and the fixing frame 3, so that the push assembly 5 pushes the chamfer template to a suitable outer size, and finally tighten the slider bolt 54 to complete the adjustment operation of the chamfer template system; then the chamfer template system is hoisted on the top hat template through the lifting ear 6, and it is stably and reliably fixedly connected to the top hat template through the heavy fixing rod 8 of the chamfer template system.

[0052] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
