Description

Technical Field

[0001] This utility model relates to the field of template technology for precast pier bodies, and in particular to a construction platform and a precast pier body inner mold. Background Technology

[0002] The pier is the main supporting structure of a multi-span bridge, primarily made of wood, stone, concrete, reinforced concrete, and steel. Precast pier construction is a bridge building technique that involves prefabricating components in a factory or on-site, then transporting them to the site for assembly. This improves construction efficiency, reduces costs, and minimizes environmental impact. The precast components of the pier are made by pouring concrete into precast pier formwork.

[0003] The precast formwork for the pier body includes a vertical inner mold, which serves as a carrier to bear the construction load during concrete pouring and to control the size and position of the inner cavity of the precast pier body.

[0004] like Figure 1 and Figure 2 As shown, the space between the inner cavity 100 of the precast pier body and the formwork hoisting outlet 200 at the top of the pier body is narrow. The existing vertical inner formwork structure is complex. When disassembling the vertical inner formwork, the construction platform needs to be removed. However, during the construction of the vertical inner formwork, the construction platform needs to be used to support the construction personnel. This repeated disassembly and assembly of the construction platform seriously affects the construction efficiency. Utility Model Content

[0005] In view of this, the present invention provides a construction platform for the precast pier inner mold and the precast pier inner mold, which can avoid repeated disassembly and assembly of the construction platform and improve construction efficiency.

[0006] To achieve the above objectives:

[0007] This utility model provides a construction platform for a precast pier inner mold, the precast pier inner mold including a transverse bridge mold, the construction platform being rotatably mounted on the back of the transverse bridge mold along the length direction of the transverse bridge mold; the construction platform is provided with a movable fixing member, the movable fixing member being detachably connected to the transverse bridge mold when the construction platform is rotated to a position close to the back frame of the transverse bridge mold.

[0008] In one embodiment, the construction platform includes a traveling plate and a movable support; wherein the traveling plate is arranged along the length direction of the transverse bridge formwork, the movable support is located at both ends of the traveling plate, and the movable support is arranged in a direction perpendicular to the length direction of the transverse bridge formwork; one end of the movable support is rotatably connected to the back frame of the transverse bridge formwork.

[0009] In one embodiment, the movable support is a bent plate, which includes a first extension and a second extension that are perpendicularly connected to each other; wherein, both ends of the traveling plate are respectively attached to the first extension and detachably connected to the second extension; one end of the second extension is hinged to the back frame of the cross bridge mold.

[0010] In one embodiment, reinforcing ribs are provided at both ends of the first extension.

[0011] In one embodiment, the second extension is hinged to one end of the back frame of the cross bridge mold and is provided with a hinged reinforcing plate.

[0012] In one embodiment, the back frame of the cross bridge mold is provided with two hinged lugs, which are arranged along a direction perpendicular to the length direction of the cross bridge mold. The second extension is hinged to one end of the back frame of the cross bridge mold, and the hinged reinforcing plate is hinged to the two hinged lugs. The gap between the two hinged lugs is greater than the sum of the thickness of the end of the second extension hinged to the back frame of the cross bridge mold and the thickness of the hinged reinforcing plate.

[0013] In one embodiment, the construction platform further includes a guardrail, with a guardrail insert provided at one end of the first extension away from the back frame of the transverse bridge formwork, and the bottom two ends of the guardrail inserted into the guardrail insert; the back frame of the transverse bridge formwork is provided with a first hook for hooking the guardrail. In one embodiment, the bottom two ends of the guardrail extend through the first extension for a predetermined length.

[0014] In one embodiment, the movable fixing member is a rope-like structure, and the two ends of the rope-like structure are provided with second hooks; one of the second hooks is hooked onto the construction platform, and the other of the second hooks is used to hook onto the cross bridge formwork.

[0015] Based on the same concept as the aforementioned utility model, this utility model also provides a precast pier inner mold, wherein the precast pier inner mold can be provided with a construction platform as described above.

[0016] This utility model provides a construction platform and a precast pier inner mold. The construction platform is rotatably connected to the back frame of the transverse bridge mold of the precast pier inner mold. In the demolding state, firstly, the guardrail hooks on the construction platform are removed from the first hook on the transverse bridge mold. The construction platform is then rotated to a position close to the back frame of the transverse bridge mold. Next, movable fasteners are used to fix the construction platform to the transverse bridge mold. After the remaining templates and movable blocks on both sides of the transverse bridge mold retract, the precast pier inner mold is hoisted out from the template hoisting outlet at the top of the pier. The precast pier inner mold is then... During the next assembly, the construction platform only needs to be flipped to a horizontal position after the remaining templates and movable blocks on both sides of the cross bridge formwork are unfolded. This avoids repeated disassembly and assembly of the construction platform, reduces the workload, and improves construction efficiency. The hinged ear plates on the back frame of the cross bridge formwork have an adjustment gap between the hinged parts of the movable support and the hinged parts of the frame, which can avoid assembly errors caused by processing and reduce assembly difficulty. The walking boards of the construction platform can use standard steel scaffolding boards, and the main body of the movable support is a bent plate, which effectively reduces the weight of the construction platform and the production and processing costs.

[0034] The term “include” or any other variation thereof is intended to cover non-exclusive inclusion, which includes not only those elements listed, but also other elements not expressly listed.

[0035] like Figures 3 to 7 As shown in the embodiment of this application, the construction platform 20 of the precast pier inner mold is rotatably disposed on the back of the transverse bridge mold 10 along the length direction of the transverse bridge mold 10 of the precast pier inner mold, i.e., the back frame 102; the construction platform 20 is provided with a movable fixing member 30, which is used to detachably connect to the transverse bridge mold 10 when the construction platform 20 rotates to a position close to the back frame 102 of the transverse bridge mold 10.

[0036] The construction platform 20 of the precast pier inner mold in this embodiment is rotatably connected to the back frame 102 of the transverse bridge mold 10. In the demolding state, the guardrail 40 on the construction platform 20 is first removed and hung on the first hook reserved on the back frame 102 of the transverse bridge mold 10. The construction platform 20 is then rotated to a position close to the back frame 102 of the transverse bridge mold 10. Then, the construction platform 20 is fixed to the back frame 102 of the transverse bridge mold 10 using movable fasteners 30. After the remaining templates and movable blocks on both sides of the transverse bridge mold 10 are retracted, the inner mold of the precast pier is hoisted out from the template hoisting outlet at the top of the pier. During the next assembly construction, the inner mold of the precast pier only needs to be unfolded after the remaining templates and movable blocks on both sides of the transverse bridge mold 10 are unfolded, and the construction platform 20 is rotated to a horizontal position. This avoids repeated disassembly and assembly of the construction platform 20, reduces the amount of construction work, and improves construction efficiency.

[0037] like Figures 5 to 7 As shown, in one embodiment, the movable fixing member 30 is a rope-like structure with second hooks 302 at both ends; one second hook 302 is hooked onto the construction platform 20, and the other second hook 302 is used to hook onto the transverse bridge formwork 10. Specifically, the movable fixing member 30 is a double-hook stainless steel wire rope, which effectively reduces production and processing costs. When dismantling the formwork, the guardrail 40 is removed, and the movable support 23 is rotated to the upper or lower part of the back frame 102 of the transverse bridge formwork 10 via the hinge pin 60. The double-hook stainless steel rope is fixed to the template connection hole 104 on the upper part of the transverse bridge formwork 10 through the reserved fixing hole 230 on the movable support 23. Then, the connecting bolts between the transverse bridge formwork 10 and the transverse bridge movable blocks, the oblique corner formwork, the longitudinal bridge movable blocks and the flat corner formwork on both sides are removed. The oblique support rod is contracted to loosen the inner formwork and the pier body. After the inner formwork is loosened, the construction platform 20 is rotated to contract to a suitable position. After the inner formwork is fixed, the pier body is hoisted out, realizing quick installation and dismantling and improving construction efficiency.

[0038] like Figure 5 As shown, in one embodiment, the construction platform 20 includes a traveling plate 21 and a movable support 23; wherein, the traveling plate 21 is arranged along the length direction of the transverse bridge formwork 10, i.e., as shown in the figure. Figure 5In the X direction shown, the movable brackets 23 are located at both ends of the traveling plate 21. The movable brackets 23 are arranged in a direction perpendicular to the length direction of the transverse bridge mold 10, i.e., as shown in the figure. Figure 5 The Y direction is shown; one end of the movable bracket 23 is rotatably connected to the back frame 102 of the cross bridge mold 10. As shown... Figures 8 to 12 As shown, in one embodiment, the movable support 23 is a bent plate, which includes a first extension 232 and a second extension 234 that are perpendicularly connected to each other; wherein, both ends of the traveling plate 21 are respectively attached to the first extension 232 and detachably connected to the second extension 234; one end of the second extension 234 is hinged to the back frame 102 of the cross bridge mold 10. Specifically, both ends of the traveling plate 21 are connected to the second extension 234 as a whole by bolts, and the second extension 234 and the end of the traveling plate 21 are provided with traveling plate mounting holes at intervals.

[0039] like Figures 8 to 10 As shown, in one embodiment, the first extension 232 has reinforcing ribs 236 at both ends. By further providing reinforcing ribs 236, the structural strength of the construction platform 20 can be greatly improved, and the construction risk can be reduced. In one embodiment, the second extension 234 is hinged to the back frame 102 of the cross bridge formwork 10 at one end and has a hinged reinforcing plate 238. Figure 11 and Figure 12 As shown, in one embodiment, the back frame 102 of the cross bridge mold 10 is provided with two hinged ear plates 104. The second extension 234 is hinged to one end of the back frame 102 of the cross bridge mold 10, and the hinged reinforcing plate 238 is hinged to the two hinged ear plates 104. The two hinged ear plates 104 are spaced apart along a direction perpendicular to the length direction of the cross bridge mold 10. The gap between the two hinged ear plates 104 is greater than the sum of the thickness of the end of the second extension 234 hinged to the back frame 102 of the cross bridge mold 10 and the thickness of the hinged reinforcing plate 238.

[0040] like Figure 11 and Figure 12 As shown, specifically, the hinged ear plate 106 on the back frame 102 of the cross bridge formwork 10 and the hinged part of the movable support 23, that is, between one end of the second extension 234 and the hinged reinforcing plate 238, are provided with an adjustment gap, which can avoid the assembly error caused by the processing of the movable support 23 and reduce the assembly difficulty of the construction platform 20. The walking board 21 of the construction platform 20 can be a standard steel scaffold board, and the main body of the movable support 23 is a bent plate, which effectively reduces the weight and production and processing cost of the construction platform 20, and makes it easy for construction personnel to quickly move it without the aid of machinery, thus reducing the assembly difficulty.

[0041] like Figure 13 and Figure 14As shown, in one embodiment, the inner mold also includes a guardrail 40. A guardrail insert 50 is provided at one end of the back frame 102 away from the cross-bridge mold 10 on the first extension 232. The bottom two ends of the guardrail 40 are inserted into the guardrail insert 50. The back frame 102 of the cross-bridge mold 10 is provided with a first hook for hooking the guardrail 40. In one embodiment, the bottom two ends of the guardrail 40 extend downwards through the first extension 232 by a predetermined length. Guardrail mounting holes are pre-drilled on the first extension 232 at positions corresponding to the guardrail insert 50, facilitating the bottom of the guardrail 40 to pass through the first extension 232. The side of the guardrail insert 50 is fastened to the second extension 234 with bolts. The lower crossbar of the guardrail 40 supports the entire guardrail 40 through the guardrail insert 50, while simultaneously preventing tools on the traveling plate 21 from falling from a height. Specifically, after the guardrail 40 is inserted into the guardrail insert 50, it extends beyond the movable bracket 23 by a predetermined length, for example, about 10mm. This prevents the guardrail 40 from falling and effectively avoids construction risks. Specifically, the guardrail insert 50 is connected to the second extension 234 by fastening bolts, which is structurally stable and reliable, and easy to install, disassemble and maintain. After the inner mold is assembled, the movable bracket 23 is hinged to the hinge ear plate 104 on the back frame 102 of the cross bridge mold 10 by hinge pin 60. After the guardrail 40 is inserted into the guardrail insert 50, the guardrail 40 is fixed by the fastening bolts on the guardrail insert 50. The movable fixing part 30 is provided in the reserved fixing hole 230 on the movable bracket 23. Specifically, the reserved fixing hole 230 is provided at one end of the second extension 234, which is convenient to find when the movable fixing part 30 is needed to fix the construction platform 20 on the cross bridge mold 10.

[0042] Based on the same concept as the foregoing embodiments, this application also provides a precast pier inner mold, which can be used to set up a construction platform with the precast pier inner mold as described in the foregoing embodiments.

[0043] As can be seen from the above embodiments, the construction platform and the precast pier inner mold involved in this application can avoid repeated disassembly and assembly of the construction platform and improve construction efficiency.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily obtained by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
