[0048] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0049] Those skilled in the art will appreciate that, unless otherwise stated, the "said" and "the" used herein may also include plural forms. It should be understood that when we refer to an element as being "connected" or "coupled" to another element, the element may be directly connected or coupled to the other element, or may refer to a connection relationship between the element and the other element through an intermediate element.

[0050] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0051] Against the backdrop of accelerated urbanization, various types of roads and facilities are increasing day by day. In urban transportation construction projects, it is often necessary to build overpasses, viaducts or other bridges with piers supporting the upper cap beams.

[0052] The manufacture of a large-span cantilever cap beam for a double-column pier requires a cap beam formwork, which needs to be supported by a cap beam bracket. Generally, it is necessary to first embed a steel plate on the side of the pier column and weld it to a triangular bracket, and then support the cap beam formwork above. However, the cost of using the embedded steel plate welding process is relatively high. Specifically, burying the embedded steel plate consumes a large amount of steel, and the embedded steel plate needs to be welded or cut and cannot be reused, resulting in excessively high costs.

[0053] Moreover, the requirements for welding quality are relatively high, which is not only labor-intensive and time-consuming but also difficult to ensure quality.

[0054] Furthermore, for large-span cantilever cap beams, the temporary structural design needs to reduce the span and lower the deflection of the load-bearing beam, which requires the removal of the embedded steel plates and triangular brackets. When the brackets are dismantled, the welds need to be cut manually, which has low turnover efficiency and is easy to damage the material during cutting, resulting in reduced material performance and a safety hazard in the subsequent use of the cap beam brackets.

[0055] The cap beam bracket and the installation method thereof provided in this application are intended to solve the above-mentioned technical problems of the related technology.

[0056] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0057] like Figure 1 As shown, the embodiment of the present application provides a double-column pier long-span cantilever cap beam bracket 100 for supporting a cap beam 300 above a pier column 200. The cap beam bracket 100 includes: at least two triangular brackets 10 configured for each pier column 200, at least one set of first screw rods 20 and at least one set of second screw rods 30.

[0058] In the transverse direction, the two triangular brackets 10 are symmetrically distributed about the pier 200. The transverse direction is the direction in which the two piers 200 are arranged in the horizontal plane.

[0059] The triangular bracket 10 comprises a cross beam 11, a vertical beam 12 and an oblique beam 13 which are fixedly connected, and the cross beam 11 is located at the top.

[0060] The first screw rod 20 passes through the pier 200 in the transverse direction, and both ends are detachably connected to the cross beams 11 of two triangular brackets 10 symmetrically distributed about the pier 200 axis.

[0061] The second screw rod 30 passes through the pier 200 in the transverse direction, and both ends are detachably connected to the inclined beams 13 of two triangular brackets 10 symmetrically distributed about the pier 200 axis.

[0062] In this embodiment, every two triangular brackets 10 are symmetrically distributed on both sides of the pier 200 in a transverse direction, and the two triangular brackets 10 are connected in a detachable manner by the first screw rod 20 and the second screw rod 30 to form an integral structure to bear the force together. The force on the upper cap beam 300 supported by the triangular bracket 10 is mainly tensile force that is dispersed and transmitted to the first screw rod 20, and mainly shear force that is dispersed and transmitted to the second screw rod 30. The first screw rod 20 is tensile, the second screw rod 30 is sheared, and the pier 200 is compressed, which can bear the weight of the entire cap beam 300. The present application replaces welding with a detachable connection, which can ensure the structural safety of the cap beam bracket 100 itself on the basis of bearing a large load, can be quickly installed and removed, and the cap beam bracket 100 can be turned over as a whole, thereby improving the installation efficiency. Moreover, there is no need for embedded steel plates. Compared with embedded steel plates that are difficult to reuse, the high-strength first screw rod 20 and the second screw rod 30 can be reused, thereby saving costs.

[0063] Moreover, the cap beam bracket 100 provided in the embodiment of the present application does not require welding of steel plates, and does not require cutting of welds during dismantling, which can reduce the degree of damage that may occur to the material structure during dismantling and can effectively ensure the safety and stability of the overall structure.

[0064] It should be noted that in the embodiment of the present application, the transverse direction is the direction in which the two piers 200 are arranged in the horizontal plane, that is, the direction in which the cap beam 300 extends. The longitudinal direction is the direction in which the cap beam 300 is arranged in the horizontal plane, or the direction in which the road set above the cap beam 300 extends. The vertical direction is the direction perpendicular to the horizontal plane, such as the extension direction of the pier 200.

[0065] like Figure 1 As shown, in some possible embodiments, the first screw rod 20 is disposed above the second screw rod 30 .

[0066] The plurality of first screw rods 20 in each group of first screw rods 20 are arranged in sequence and spaced apart in the vertical direction, and both ends are detachably connected to the corresponding cross beams 11 of the same triangular bracket 10 .

[0067] The plurality of second screw rods 30 in each group of second screw rods 30 are arranged in sequence and spaced apart in the vertical direction, and both ends are detachably connected to the oblique beams 13 of the same corresponding triangular bracket 10 .

[0068] In this embodiment, the cross beam 11 of the triangular bracket 10 is located upward, one end of which contacts the side of the pier 200, and the other end of which extends out. One end of the inclined beam 13 is fixedly connected to the other end of the cross beam 11, and the other end of the inclined beam 13 contacts the side of the pier 200. The vertical beam 12 is vertically arranged, close to the side of the pier 200, and connected between the bottom surface of the cross beam 11 and the top surface of the inclined beam 13. The first screw rod 20 is located upward and detachably connected to the cross beam 11 of the triangular bracket 10, and the second screw rod 30 is located downward and detachably connected to the bottom end of the inclined beam 13 of the triangular bracket 10.

[0069] Moreover, if Figure 2 As shown, Figure 2 for Figure 1 In the top view schematic diagram after the cap beam 300 is omitted, each group of first screw rods 20 includes a plurality of first screw rods 20 arranged at vertical intervals, each first screw rod 20 extends laterally, and one end of the crossbeam 11 has a certain size in the vertical direction, and can be detachably connected to the plurality of first screw rods 20 arranged at vertical intervals at the same time, thereby enhancing the connection stability between the first screw rods 20 and the triangular bracket 10, and thereby increasing the load-bearing capacity of the cap beam bracket 100.

[0070] like Figure 3 As shown, in some possible embodiments, the end of the crossbeam 11 has a connecting plate 14 , which is attached to the side of the pier 200 and is detachably connected to the end of the first screw rod 20 extending out of the pier 200 .

[0071] In this embodiment, the connecting plate 14 has a certain area in the vertical plane and can fit with the side of the pier 200, so that the contact area between the triangular bracket 10 and the side of the pier 200 is larger, and it can be detachably connected to multiple first screw rods 20 at the same time.

[0072] Alternatively, if Figure 3 As shown, the connecting plate 14 has a plurality of connecting holes, and the ends of the first screw rod 20 are inserted into the connecting holes and fixed with nuts 90. The operation is simple and the nuts 90 can also effectively prevent the triangular bracket 10 from tipping over.

[0073] Optionally, the end of the inclined beam 13 also has a connecting plate 14, which is attached to the side of the pier 200 and is detachably connected to the end of the second screw rod 30 extending out of the pier 200 through a nut 90.

[0074] like Figure 1 As shown, in some possible embodiments, at least two triangular brackets 10 are disposed on the same side of the pier 200 along the longitudinal direction in the horizontal plane.

[0075] The plurality of first screw rods 20 are arranged along a longitudinal spacing in a horizontal plane.

[0076] In this embodiment, the longitudinal side of the pier 200 also has a certain size. A plurality of triangular brackets 10 are arranged on the same side of the pier 200 , which are detachably connected to a plurality of groups of first screw rods 20 , respectively, and can increase the longitudinal load of the cap beam bracket 100 .

[0077] like Figure 4 As shown, in some possible embodiments, the cap beam bracket 100 further includes: a connecting member 40 connected between adjacent triangular brackets 10 arranged on the same side of the pier 200 .

[0078] In this embodiment, the connecting member 40 connects the triangular brackets 10 arranged on the same side into a whole, thereby enhancing the stability of the cap beam bracket 100 .

[0079] In some possible embodiments, the triangular brackets 10 disposed on the same side of the pier 200 have the same height.

[0080] In this embodiment, the heights of the triangular brackets 10 are all consistent, so that structures such as the load-bearing beam 50 can be easily arranged on the triangular brackets 10 on the same side.

[0081] In some possible embodiments, Figure 1 and Figure 4 As shown, the cap beam bracket 100 also includes: a load-bearing beam 50, which is arranged longitudinally in the horizontal plane above the cross beams 11 of the multiple triangular brackets 10 arranged on the same side of the pier 200.

[0082] In this embodiment, the load-bearing beam 50 is located above the triangular bracket 10 and extends longitudinally to prevent overturning.

[0083] Optionally, angle steel is used as a flat link to connect the load-bearing beam 50 into a whole to prevent overturning, which can enhance the overall stability of the cap beam bracket 100 and further improve construction safety.

[0084] like Figure 1 and Figure 4 As shown, in some possible embodiments, the cap beam bracket 100 further includes: a discharge block 60 , a Bailey frame 70 and a distribution beam 80 .

[0085] The unloading block 60 is disposed above the load-bearing beam 50 .

[0086] The Bailey rack 70 is disposed laterally above the unloading block 60 .

[0087] The distribution beams 80 are arranged between the Bailey frames 70 and the cap beams 300 at intervals in the lateral direction.

[0088] In this embodiment, the unloading block 60, the Bailey frame 70 and the distribution beam 80 are stacked on the load-bearing beam 50 in sequence, and the top distribution beam 80 supports the cap beam 300. The unloading block 60 can adjust the elevation of the upper Bailey frame 70 to ensure that after the concrete of the cap beam 300 reaches sufficient strength, the temporary support load can be safely and smoothly transferred to the main body of the cap beam 300 to complete the unloading process of the bracket. The Bailey frame 70 can protect the construction working surface and ensure that the cap beam 300 reaches the designed size. The distribution beam 80 can distribute the load to the Bailey frame 70 below in the lateral direction.

[0089] Based on the same inventive concept, the present application embodiment also provides a method for installing any cap beam bracket 100 provided in the above embodiments. The flow chart of the method is as follows: Figure 5 As shown, the method includes steps S101 to S104:

[0090] S101: Thread at least one set of first lead screws 20 and at least one set of second lead screws 30 through the pier column 200.

[0091] S102: Symmetrically arrange the triangular brackets 10 on both sides of the pier column 200 along the transverse direction with respect to the axis of symmetry of the pier column 200.

[0092] S103: Removably connect both ends of the first lead screw 20 to the cross beams 11 of two triangular brackets 10 that are symmetrically distributed with respect to the axis of symmetry of the pier column 200.

[0095] In this embodiment, both the first lead screw 20 and the second lead screw 30 are threaded through the corresponding positions reserved in the pier column 200, and then the triangular brackets 10 are arranged on both sides of the pier column 200. Both ends of the first lead screw 20 are removably connected to the cross beams 11 of two triangular brackets 10 that are symmetrically distributed with respect to the axis of symmetry of the pier column 200, and both ends of the second lead screw 30 are removably connected to the inclined beams 13 of two triangular brackets 10 that are symmetrically distributed with respect to the axis of symmetry of the pier column 200. The triangular brackets 10 and the first lead screw 20 and the second lead screw 30 bear the load together. The first lead screw 20 is in tension, the second lead screw 30 is in shear, and the pier body is in compression, and can bear the weight of the entire cap beam 300. By using the detachable connection method instead of welding in this application, the structural safety of the cap beam bracket 100 itself can be ensured on the basis of bearing a large load, and it can be quickly installed and removed. The cap beam bracket 100 can be rotated as a whole, improving the installation efficiency. Moreover, there is no need to embed steel plates, which can save costs.

[0096] Furthermore, the cap beam bracket 100 provided in the embodiment of the present application does not require welding of steel plates, and there is no need to cut the welds during demolition, which can reduce the possible damage to the material structure during demolition and effectively ensure the safety and stability of the overall structure.

[0097] Optionally, pipes can be embedded in the pier column 200 and positioned with "well"-shaped steel bars; then, the first lead screw 20 and the second lead screw 30 are passed through the pipes and the triangular brackets 10 are installed, and the nuts 90 are tightened so that the triangular brackets 10 are removably connected to the first lead screw 20 and the second lead screw 30.

[0098] In some possible embodiments, the installation method of the cap beam bracket 100 provided in the embodiment of the present application further includes the following steps:

[0099] A load-bearing beam 50 , a discharge block 60 , a Bailey frame 70 and a distribution beam 80 are sequentially arranged above the triangular bracket 10 , so that the distribution beam 80 supports the cap beam 300 .

[0100] In this embodiment, after the triangular bracket 10 is installed, a load-bearing beam 50, a drop block 60, a Bailey frame 70 and a distribution beam 80 are sequentially arranged above the triangular bracket 10. The distribution beam 80 supports the cap beam 300 above, so that the cap beam 300 has effective support and sufficient safety. The cap beam bracket 100 has certain versatility and economy, and can also improve turnover efficiency and installation efficiency.

[0105] Optionally, the step of installing the distribution beam 80 in the above steps may include the following steps:

[0106] Distribution beams 80 are arranged on the Bailey frame 70 at intervals in the transverse direction.

[0107] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:
