Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of storage equipment for prefabricated beam construction templates, in particular to a storage system for prefabricated box beam inner templates. Background Art
[0002] Box girders are required in the construction of bridges and highway projects. Reinforced concrete box girders are one of the important structures in bridge projects. According to the method of concrete pouring, they are divided into prefabricated box girders and cast-in-place box girders. Cast-in-place box girders refer to box girders directly cast at the construction site, while prefabricated box girders are prefabricated in advance in an independent site, and then hoisted after the lower structure of the beam is completed. In order to facilitate construction, box girders are mostly prefabricated in the form of production lines, and then the prefabricated box girders are sent to the construction site for assembly by means of transportation. The production line in the beam manufacturing site has different areas, including steel bar storage area, steel bar binding area, beam casting area, curing area and inner mold storage area. The curing area, beam casting area and inner mold storage area are arranged along the longitudinal direction of the beam body, and the work flow of each area is completed by means of transportation.
[0003] The box girder is a hollow box-type structure. When the box girder is prefabricated and cast, a bottom mold, an inner mold and an outer mold are provided for forming the beam body of the prefabricated box girder. After the beam body is cast and formed in the beam body casting area, the inner mold needs to be demolded and dragged out of the beam body cavity from the beam end and transferred to the inner mold storage area. After the hardness of the beam body reaches the standard, the outer molds on both sides of the beam body are demolded. After the outer molds are demolded, there is no need to transfer them to other work areas. The bottom mold trolley needs to transport the bottom mold supporting the beam body to the curing area to complete the beam body curing, and then enter the next beam body casting stage. The bottom mold and inner mold need to be transported back to the beam body casting area.
[0004] In order to store the inner formwork of the box girder, a box girder inner formwork storage bracket is generally set up in the inner formwork storage area. The existing inner formwork storage bracket cannot realize the self-propelled movement of the bottom formwork trolley through the inner formwork storage area, so the self-propelled circulation of the bottom formwork trolley carrying the bottom formwork cannot be realized. The bottom formwork trolley can only be hoisted to the beam casting area by hoisting. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, the storage system for the inner mold of the prefabricated box beam of the embodiment of the present application includes a bracket assembly 10 arranged along a first direction, the bracket assembly 10 includes two side support parts 102 arranged opposite to each other and a top support part 104 arranged on the top of the two side support parts 102, a travel channel 106 is formed between the two side support parts 102, the travel channel 106 is used for the bottom mold trolley carrying the bottom mold to pass through, and the travel channel 106 extends along the first direction; the top of the top support part 104 is spaced apart with an inner mold support module 20, the inner mold support module 20 is used to support the lateral sides and bottom of the inner mold of the prefabricated box beam, so as to realize the storage of the inner mold of the prefabricated box beam in the bracket assembly 10 along the first direction. Specifically, in this embodiment, the first direction is the longitudinal direction of the prefabricated box beam body, that is, Figure 1The second direction is the X direction of the precast box girder, that is, Figure 1 in the Y direction.
[0028] The storage system for the inner mold of the precast box beam provided in the embodiment of the present application has a gate structure formed by the bracket assembly 10 consisting of relatively arranged two side support parts 102 and the top support part 104 arranged on the top of the two side support parts 102. The bracket assembly 10 is open at both opposite ends along the longitudinal direction of the precast box beam body to form a walking channel for the bottom mold trolley, which not only retains the storage function of the inner mold of the precast box beam on the top of the bracket assembly, but also enables the bottom mold trolley carrying the bottom mold to pass through the inner mold storage area, so that the bottom mold trolley carrying the bottom mold can be self-propelled and circulated in the factory. The structure is simple, economical and practical, which is convenient for construction personnel to complete the grinding, cleaning and application of release agent of residual concrete of the inner mold at the top support part of the bracket assembly. It is especially suitable for integral inner molds with a longer length. By arranging a winch at the first end of the bracket assembly for demolding the inner mold, the storage system for the inner mold of the precast box beam has both the demolding function and the inner mold storage and preparation functions for the next beam making cycle.
[0029] like Figures 1 to 4 As shown, in one embodiment, the bracket assembly 10 includes N groups of sub-bracket assemblies 101 arranged along a first direction, where N is a positive integer greater than or equal to 2. The sub-bracket assemblies 101 include two oppositely disposed sub-side support portions 1021 and a sub-top support portion 1041 disposed on top of the two sub-side support portions 1021. The N groups of sub-bracket assemblies 101 are spaced apart, with a transition platform 30 disposed between adjacent groups of sub-bracket assemblies 101. A transition support assembly 40 is disposed at the bottom of the transition platform 30 between adjacent groups of sub-bracket assemblies 101. In one embodiment, the transition platform 30 is disposed on the top of the top support portion 104 along the first direction. The transition platform 30 is disposed relative to the outer side of the inner mold support module 20 along a second direction perpendicular to the first direction.
[0030] Specifically, in one embodiment, the side supports 102, the sub-side supports 1021, the top supports 104, and the sub-top supports 1041 are all composed of multiple groups of interconnected support rods arranged horizontally, vertically, and diagonally, resulting in a simple structure, stability, reliability, and small space occupation. In an embodiment not shown, the side supports 102 and the sub-side supports 1021 can each be composed of other support structures such as legs and brackets, and the top supports 104 and the sub-top supports 1041 can also be composed of support structures such as support plates and support frames. Specifically, by configuring the bracket assembly 10 to be composed of multiple groups of sub-bracket assemblies 101 and providing a transition platform 30, the overall length of the bracket assembly 10 can be adjusted according to the length of the integral inner mold, thereby greatly improving the applicability of the storage system. By providing the transition platform 30, after the inner mold is removed, construction workers can stand directly on the bracket assembly 10 to complete tasks such as polishing, cleaning, and applying mold release agent to the mold, thereby greatly reducing workload and avoiding safety hazards. The precast box girder inner mold does not need to be hoisted to the ground, thereby avoiding the problems of large space occupation, cluttered beam yards, and difficult management, as well as safety hazards. Specifically, by providing a transition support assembly 40 at the bottom of the transition platform 30 between two adjacent sub-bracket assemblies 101, the stability and reliability of the storage system for the precast box girder inner mold can be greatly improved. Specifically, in one embodiment, the transition support assembly 40 is composed of multiple groups of horizontally and vertically arranged support rods connected to each other to form a support structure, with support feet provided at the bottom of the support structure. The structure is simple, stable, reliable, and takes up little space.
[0031] like Figure 3 and Figure 4As shown, in one embodiment, the transition platform 30 includes a walking board 301, with guardrails 50 disposed on the outside of the walking board 301 along a first direction. Bracket connecting plates 302 are spaced apart on both sides of the walking board 301 extending along the first direction. The bracket connecting plates 302 are connected to the top of the top support portion 104. Specifically, the guardrails 50 disposed on the outside of the transition platform 30 provide protection for construction workers and further prevent safety accidents. The bracket connecting plates 302 disposed on the sides of the walking board 301 help ensure a stable and reliable connection between the transition platform 30 and the top support portion 104. In one embodiment, a work ladder assembly 70 is disposed on the outside of the first end of the storage system along a second direction extending perpendicular to the first direction. The work ladder assembly 70 facilitates construction workers' climbing to perform tasks such as polishing, cleaning, and applying release agent to the formwork. This enables the storage system for the inner formwork of precast box beams to function as both a demolding system and an inner formwork storage system for preparing for the next beam production cycle. Specifically, the working ladder assembly 70 includes a pedal unit and guardrails provided on both sides of the pedal unit, wherein the pedal in the pedal unit remains horizontal and cannot rotate, and adjustment parts are provided on both sides of the bottom of the pedal unit. The adjustment parts are used to adjust the inclination of the working ladder assembly 70 to adapt to different working scenarios. The adjustment parts can be a connection structure in which a screw and a nut cooperate with each other. The screw passes through the mounting holes on both sides of the bottom of the pedal unit, and the nut fastens the screw to the bottom of the pedal unit. The inclination of the working ladder assembly 70 is adjusted by adjusting the longitudinal support length of the screw.
[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the top of the first end of the storage system lacks an inner mold support module 20 and is instead equipped with a winch. Specifically, the top sub-top support portion 1041 of the first sub-bracket assembly 101 lacks an inner mold support module 20. Instead, a winch is installed on the sub-top support portion 1041 of the first sub-bracket assembly 101. A working ladder assembly 70 is installed on the outer side of the first sub-bracket assembly 101, extending in a second direction perpendicular to the first direction. Specifically, by installing a winch on the sub-bracket assembly 101 near the inner mold of the precast box girder, the inner mold of the precast box girder can be demolded, eliminating the need for hoisting.
[0033] like Figure 1 and Figure 2As shown, in one embodiment, first diagonal supports 108 are symmetrically provided on the sub-side supports 1021 of the first and Nth sub-bracket assemblies 101. Specifically, the additional symmetrical first diagonal supports 108 are provided on the sub-bracket assembly 101 housing the winch and the sub-bracket assembly 101 housing the end-of-mold removal. This ensures the stability and reliability of the storage system during the placement and removal of the precast box girder inner molds, preventing potential safety incidents. Specifically, the first diagonal supports 108 are preferably telescopic support rods, which are simple and compact, easy to install and deploy, and stable, reliable, and easily adjustable.
[0034] like Figures 1 to 4 As shown, in one embodiment, the inner mold support module 20 includes a first roller assembly 205, a support block 201 and a second roller assembly 203; wherein, the support block 201 is relatively arranged along a second direction perpendicular to the first direction, the second roller assembly 203 is arranged on the inner side of the support block 201, and the first roller assembly 205 is arranged on the two outer sides of the top support portion 104 opposite to each other along the first direction, and the first roller assembly 205 is arranged along the second direction; the second roller assembly 203 is used to support the lateral sides of the prefabricated box beam inner mold, and the first roller assembly 205 is used to support the bottom of the prefabricated box beam inner mold to provide rolling support for the prefabricated box beam inner mold to move along the first direction. Specifically, by arranging the first roller assembly 205 and the second roller assembly 203 in conjunction with the support block 201, the precast box girder inner mold can be effectively rolled and supported from the sides and bottom, providing a stable and reliable guide during the storage and removal of the precast box girder inner mold. Furthermore, the placement of the first roller assembly 205 on the outside of the top support portion 104 helps reduce the overall height of the support module 20, thereby facilitating stable and reliable support of the precast box girder inner mold by the support module 20. Specifically, the first roller assembly 205 and the second roller assembly 203 each include a mounting base 207, a positioning shaft 208, and a roller 209. The positioning shaft 208 is fixedly mounted on the mounting base 207, and the roller 209 is rotatably mounted on the positioning shaft 208, resulting in a simple, stable, and reliable structure. Specifically, the rolling support and guiding action of the two roller assemblies in the inner mold support module 20 make the demolding and storage of longer, integral inner molds more convenient, stable, and reliable.
[0035] like Figure 2 and Figure 4As shown, in one embodiment, the side support portion 102 is a bracket structure, and second oblique support members 110 connected to the top support portion 104 are provided at opposite ends of the bracket structure along a first direction. The connection between the second oblique support member 110 and the top support portion 104 is located near the connection between the side support portion 102 and the top support portion 104. Specifically, the second oblique support member 110 is provided near the connection between the side support portion 102 and the top support portion 104 at the opening of the bracket assembly 10. This can further enhance the structural strength and stability of the bracket assembly 10 while preventing interference when the bottom mold trolley passes through the inner mold storage area. Specifically, the second oblique support member 110 is a rod-shaped structure, which is easy to manufacture and has low cost.
[0036] like Figures 1 to 3 As shown, in one embodiment, an adjustable support assembly 60 is provided at the bottom of the sub-side support portion 1021 of the side support portion 102. The adjustable support assembly 60 includes a support base 601 and a fastening assembly 602. The fastening assembly 602 is fixedly connected to the sub-side support portion 1021, and the support base 601 is movably connected to the fastening assembly 602 in a vertical direction. Specifically, the provision of the adjustable support assembly 60 facilitates adjustment of the overall height of the bracket assembly 10 according to the actual conditions of the construction site, thereby ensuring smooth construction. Specifically, the fastening assembly 602 can be a nut threadedly connected to the support base 601.
[0037] According to the above embodiments, it can be seen that the storage system for the inner mold of the prefabricated box beam involved in the present application, by setting a bracket assembly of a portal structure, the bracket assembly is open at both opposite ends along the longitudinal direction of the prefabricated box beam body to form a running channel for the bottom mold trolley, which not only retains the storage function of the inner mold of the prefabricated box beam on the top of the bracket assembly, but also enables the bottom mold trolley carrying the bottom mold to pass through the inner mold storage area, thereby enabling the bottom mold trolley carrying the bottom mold to move self-propelled in the factory, with a simple structure, economical and practical, and convenient for construction personnel to complete the grinding, cleaning and release agent application of the residual concrete of the inner mold at the top support part of the bracket assembly, and is particularly suitable for the storage of integral inner molds with a longer length.
