[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] The pier construction platform in this application is mainly used to assist in the casting construction of the pier. The construction platform is formed by relying on the casting formwork of the pier. The construction platform can be built without setting up additional supports or scaffolding. It is used to provide support for pier construction when the terrain conditions are complex, the construction period is tight, and the construction pressure is high.

[0039] The main components are assembled and installed in the form of detachable connections, which can facilitate the dismantling of the construction platform and the transportation of separate components, greatly improving the operating conditions and increasing construction efficiency.

[0040] See also Figure 1 , and combined with Figure 2-Figure 3 The pier construction platform in this application is mainly used for building a construction platform during the pier casting construction process. The main structure of the construction platform includes a walking platform 3 and a platform bracket. A casting template 1 is built before the pier is formed. The platform bracket relies on the structure of the casting template 1 and is arranged around the periphery of the casting template 1 to provide root support for the construction platform.

[0041] The walking platform 3 is overlapped between the platform brackets, and the walking platform 3 can be built on the basis of the platform brackets to meet the construction and use requirements of the walking platform 3.

[0042] From the perspective of support, the platform bracket includes a plurality of independent triangular brackets 2, each of which includes a vertical support rod 21, a horizontal support rod 22 and a diagonal support rod 23 of an integrated structure. The triangular bracket 2 is formed by the above-mentioned different support rods, which can effectively improve the structural strength of each platform bracket, and the triangular bracket 2 can form a separate support plane to ensure effective and reliable support.

[0043] The vertical support rod 21 is detachably connected to the casting template 1, so that the platform bracket can be connected to the casting template 1 to form a supporting base for the walking platform 3. At the same time, the detachable connection form facilitates the disassembly and assembly of the tripod bracket 2, which is conducive to turnover and reuse.

[0044] The walking platform 3 is detachably connected between the transverse support rods 22, so that the walking platform 3 and the tripod bracket 2 can also maintain a detachable connection relationship. On the basis of effectively forming a construction platform, the walking platform 3 can be disassembled and assembled to facilitate the turnover and reuse of the walking platform 3.

[0045] The casting formwork 1 in the utility model includes multiple sections distributed vertically. Specifically, the casting formwork 1 with multiple sections is constructed layer by layer from the bottom layer upwards. In order to facilitate construction at a high position, a platform bracket is arranged at the top position of each section of the casting formwork 1, which can effectively form a walking platform 3 located at the top of each section of the casting formwork 1, so as to facilitate the high-position construction casting of the entire section of the pier.

[0046] Based on the step-by-step construction of the casting formwork 1 from bottom to top, a ladder 7 is arranged between the walking platform 3 and the ground, and between walking platforms 3 of different heights. The arrangement of the ladder 7 can facilitate operators to climb between sections of different heights and improve the integrity of the pier construction platform.

[0047] In order to facilitate the climbing operation of personnel and to ensure the strength of the overall structure, the ladders 7 are arranged alternately between the walking platforms 3 of adjacent storeys.

[0048] The walking platforms 3 at different levels are all provided with manholes 6, which can be used for operators to climb or descend between the walking platforms 3 at different levels. Furthermore, the manhole 6 is arranged at the top of the ladder 7, opposite to the position of the ladder 7, and in order to facilitate entry and exit, the manhole 6 includes a square manhole 6 located on the walking platform 3, which is convenient for the reserved structure of the walking platform 3 during the overlapping process.

[0049] The walking platform 3 includes a plurality of independent platform panels 31 , and the plurality of platform panels 31 are assembled together to form the overall structure of the walking platform 3 .

[0050] Each platform plate 31 includes a platform outer frame and a patterned plate connected to the platform outer frame. Bolt holes are provided on the transverse support rod 22 and the platform outer frame. The platform outer frame and the transverse support rod 22 are detachably connected by bolts.

[0051] Through the above-mentioned arrangement, the disassembly and assembly of the platform plate 31 and the platform bracket can be facilitated, and the turnover utilization of the platform plate 31 can be effectively promoted while facilitating the construction of the overall structure of the walking platform 3.

[0052] From the perspective of protection, a protective net 5 is arranged on the periphery of the walking platform 3. The protective net 5 includes a straight side net 51 and an angle mold side net 52. The straight side net 51 includes a rectangular mesh surface, which is assembled with each other on the same side to form a protective net 5 structure on the side of the pier, while the angle mold side net 52 includes a curved mesh surface, which can follow and adapt to the end shape of the pier to form a relatively complete protective whole.

[0053] From the installation perspective of the protective net 5, the outer end of the transverse support rod 22 is connected to the vertically arranged protective rod 24, and the protective rods 24 are connected with a crossbeam 4. The crossbeam 4 and the protective rods 24 are detachably connected. The setting of the crossbeam 4 can provide an installation basis for the protective net 5.

[0054] Furthermore, the protective net 5 is arranged on the inner side of the protective rod 24, and the protective net 5 and the crossbeam 4 are detachably connected by a U-shaped clamp. Similarly, the detachable connection is conducive to the turnover application of the protective structure, and can reduce the difficulty of disassembly and assembly and improve construction efficiency.

[0055] At the same floor height, the platform brackets are evenly distributed around the casting formwork 1, and each triangular bracket 2 is arranged vertically to form a vertical support plane. Through multiple evenly distributed triangular support planes, a relatively uniform support can be formed to ensure the overall balance of the supporting force.

[0056] A plurality of bolt holes are arranged on the vertical support rod 21 , the casting formwork 1 comprises a main reinforcement channel steel, the main reinforcement channel steel is provided with bolt holes, and the triangular bracket 2 is detachably connected to the main reinforcement channel steel by bolts.

[0057] The triangular bracket 2 can be detachably installed on the casting template 1. The main reinforcement channel steel of the casting template 1 has a high structural strength and can provide a good supporting effect for the construction platform.

[0058] The pier column construction platform of the utility model, the casting template 1, the triangular bracket 2, the platform plate 31, the protective net 5 and the ladder 7 are all designed as independent structures, and the assembly between the components is realized by bolts. In this way, not only the structure of the entire construction platform can be simplified, but also the detachable connection of the construction platform can be realized, so as to facilitate the installation and transportation of the construction platform.

[0059] The vertical support rods 21, transverse support rods 22 and diagonal support rods 23 of the triangular bracket 2 are made of ∠75# equilateral angle steel, and the protective rods 24 are welded into a whole with □40 square tubes. The vertical support rods 21 are fixed to the main reinforcement channel steel on the outside of the pier column formwork by bolts, and the spacing between the vertical support rods 21 is not more than 1.2 meters.

[0060] The transverse support rods 22 are connected by platform plates 31, and the platform plates 31 are welded into a whole by ∠50# equilateral angle steel, 6 mm steel strip, and 3 mm patterned plate. The guard rod 24 is set at a height of 1.2 meters. The guard rods 24 are connected by beams 4 and protective nets 5 to form a circular guardrail. The protective net 5 is made of □40 square tubes and steel wire mesh welded into straight plate side nets 51 with rectangular surfaces and angle mold side nets 52 with curved surfaces.

[0061] The pier is cast in sections. First, a casting formwork 1 surrounding the bridge pier is installed at the bottom of the pier, and a triangular bracket 2 is installed around the formwork. The horizontal support rods 22 connect the walking platform 3 and the crossbeams 4 and the protective net 5 between the protective rods 24 to form a semi-enclosed construction platform.

[0062] The construction workers enter the construction platform through the ladder 7 and the manhole 6, and work on the construction platform to cast the first section of the pier column. After the first section is cast, the second section of the formwork is installed on the basis of the formwork of the first section to form a circular platform for the second section. The construction is carried out upward in sequence, and after the entire pier column is cast, the formwork is removed from top to bottom in sequence.

[0063] The entire pouring process does not require the erection of scaffolding and is not restricted by the terrain and geological structure around the pier.

[0064] In the specific steps, first install the bottom section pier column formwork, install the triangular bracket 2 on the formwork along the circumferential direction of the formwork, and complete the circumferential platform erection. Set the ladder 7 along the longitudinal direction of the formwork, use the construction platform as a pouring construction platform, and pour the first section pier column concrete;

[0065] After the first section of the pier column is poured, install the second section of the pier column reinforcement cage and set the guy rope;

[0066] Install the second section pier column formwork, construction platform and ladder 7 on the basis of the first section pier column formwork, set the formwork cable wind rope, and pour the second section pier column concrete;

[0067] Repeat the above steps and pour upwards in sequence until the top section of the pier column is poured with concrete;

[0068] The pier column formwork, construction platform and vertical ladder 7 are removed from top to bottom to complete the pier column pouring construction.

[0069] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
