Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a large cantilever cap beam template structure with gradually changing transverse slope and a construction method thereof. Background Art

[0002] like Figure 1 As shown, the large cantilever cap beam is constructed within the central green belt of an existing urban road. To enhance the aesthetic curves, the pier cap 4 is designed as a curved S-shaped cantilever cap beam structure located on the curved section of the route. The gradual cross slope results in a different slope for each large cantilever cap beam 5. During construction, maintaining access to the existing road and ensuring construction quality emphasizes the natural appearance of exposed concrete. This significantly increased the difficulty of standardizing the large cantilever cap beams of the Huavase Pier.

[0003] At present, the construction of large cantilever cap beams usually adopts the combination of buckle brackets or floor-standing steel pipe brackets + buckle brackets. The elevation is basically adjusted by the top support of the rods. The bottom formwork is spliced ​​on-site with wooden formwork. Various slopes are achieved by adjusting the top support height of the buckle brackets. The main problems during construction are as follows:

[0004] (1) The quality of the joint between the cap beam and the pier column is poor;

[0005] (2) The cap beam formwork cannot be quickly hoisted and disassembled;

[0006] (3) The template cannot be applied to different slopes, and the template investment cost is high;

[0007] (4) Safety and operability are not strong in construction environments with heavy vehicle traffic.

[0008] Construction is carried out on a busy road without closing the road. The use of disc-shaped brackets to adjust the cross slope is not very safe and the joints between the cap beam and the vase pier cap are prone to misalignment. A large amount of manpower is required to adjust the template elevation, install and disassemble the template, which not only increases the labor intensity of the workers, but also raises the risk of construction safety and quality, which is not conducive to standardized construction.

[0034] The application will be described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in further detail below with reference to the drawings and embodiments.

[0036] Referring to Figures 1 to 8 The present application provides a large cantilever cap beam formwork structure with gradual transverse slope, comprising: a common base form 1, a replacement slope starting support 2, and a side form 3.

[0037] In the present embodiment, the common base form 1 is the base form of the cap beam of the normal section (i.e. non-curved section) of the bridge.

[0038] In the present embodiment, the number of the replacement slope starting supports 2 is multiple. The top of each replacement slope starting support 2 is formed with a slope surface. The slopes of the slope surfaces of the multiple replacement slope starting supports 2 are different.

[0039] As a preferred embodiment, the slopes of the slope surfaces of the multiple replacement slope starting supports 2 are gradiently increased. Referring to Figures 5 to 8 As shown in

[0040] One replacement slope starting support 2 is supported on the common base form 1. The slope of the slope surface of one replacement slope starting support 2 is adapted to the transverse slope of the large cantilever cap beam 5.

[0041] The side form 3 comprises two common modules 31 and multiple replacement turning modules 32. Each replacement turning module 32 comprises two form sections. One end of the two form sections of one replacement turning module 32 is connected together at a preset angle. The other end of the two form sections of one replacement turning module 32 is connected to the two common modules 31 respectively. The preset angles of the one end of the two form sections of the multiple replacement turning modules 32 are different.

[0042] As a preferred embodiment, the preset angles of the one end of the two form sections of the multiple replacement turning modules 32 are gradiently increased. Referring to Figure 3 and Figure 4 As shown in

[0043] In the present embodiment, the central axis of one common module is coaxially arranged with the central axis of one form section, and the central axis of the other common module is coaxially arranged with the central axis of the other form section. In Figure 3In the embodiment, the slope of the central axis of the section of the formwork section is 2%. Figure 4 In the embodiment, the slope of the central axis of the section of the formwork section is 3%.

[0044] The opposite sides of the common base form 1 are respectively provided with side forms 3. The side forms 3 and the base form enclose a pouring space for pouring the large cantilever cap beam 5. When pouring the large cantilever cap beam 5 with different transverse slopes, the position and pose of the pouring space are adapted to the position and pose of the large cantilever cap beam 5 formwork structure by replacing the replacement slope support 2 and the replacement turning formwork which are adapted to the slope of the large cantilever cap beam 5.

[0045] In the embodiment, the bottom of the common base form 1 is provided with a support frame 11. The bottom surface of the support frame 11 is provided in the horizontal direction. The slope surface of one replacement slope support 2 is supported on the bottom surface of the support frame 11. One replacement slope support 2 is connected to the support frame 11 by fasteners.

[0046] As a preferred embodiment, one replacement slope support 2 is erected on the ground by a floor type steel pipe Bailey beam support.

[0047] The present application provides a construction method of a large cantilever cap beam formwork structure with a gradually changing transverse slope, comprising the following steps:

[0048] S1, based on the transverse slope of the large cantilever cap beam 5, one replacement slope support 2 and one replacement turning module 32 are determined.

[0049] S2, one replacement slope support 2 is erected on the ground.

[0050] S3, the common base form 1 is installed on the slope surface of one replacement slope support 2 to tilt the common base form 1 so that the slope of the common base form 1 is adapted to the transverse slope of the large cantilever cap beam 5.

[0051] S4, the other end of the two sections of the replacement turning module 32 are respectively connected to two common modules 31 to form side forms 3.

[0052] S5, the side forms 3 are respectively erected on the opposite sides of the common base form 1, and the side forms 3 and the base form enclose a pouring space for pouring the large cantilever cap beam 5, so that the position and pose of the pouring space are adapted to the position and pose of the large cantilever cap beam 5 formwork structure.

[0053] In the embodiment, the large cantilever cap beam gradually changing transverse slope of the road curve section is optimized (such as 1%, 2%, 3%, 4%), and the elevation error generated after the transverse slope is optimized is adjusted by the height of the cushion stone. When the vase pier cap 4 is constructed, the transverse slope of the top cap formwork needs to be adjusted to the corresponding optimized slope. In the case of the horizontal cap beam formwork support, the cap beam side form adjusting block and the base form replacement slope support are adjusted to the optimized slope. The gradually changing transverse slope is only classified into several slopes, and the construction difficulty is greatly reduced.

[0054] The outer edge margin of the pier cap top must be uniform. The bottom mold length of the large cantilever cap beam is fixed to ensure the uniformity of the outer side distance of the pier cap top. Otherwise, it will directly affect the tightness of the joint between the cap beam and the pier column, thereby causing quality problems, for example, the cap beam with the same cap size and curvature but with a 2% double slope and a 3% single slope, the lower cap formwork is different. To ensure that the distance from the outer side of the pier to the center of the line is equal, the influence of different slopes of the large cantilever cap beam on the installation of the bottom mold of the cantilever end of the cap beam is eliminated. When designing the cap steel formwork, this situation needs to be considered in advance, for example, the center position of the outer side of the 2% double slope and the 3% single slope pier is 5300mm.

[0055] The side mold of the cap beam realizes the slope conversion by replacing the turning module, and improves the turnover utilization rate of the cap beam formwork. The design of the side mold of the large cantilever cap beam is optimized, and the slope is adjusted by replacing the turning module to reduce the number of formworks.

[0056] The bottom mold of the cap beam realizes the slope conversion by replacing the slope support, and improves the turnover utilization rate of the formwork.

[0057] Different slopes are changed by replacing the slope support under the bottom mold, and the number of formworks is reduced. The ordinary bottom mold formwork is designed as a flat slope or one kind of slope, and the replacement of the slope support can be applied to each slope.

[0058] The cantilever end and the middle section bottom mold of the large cantilever cap beam are connected into a whole, and can be quickly hoisted during the occupation construction. The replacement of the slope support is connected with the support frame of the bottom mold through fasteners such as bolts.

[0059] The gap between the formwork of the large cantilever cap beam and the concrete pier column is 10mm in design, which is convenient for the installation and removal of the formwork.

[0060] The gap between the large cantilever cap beam and the concrete pier column is sealed by structural glue to ensure the tightness.

[0061] The support frame of the large cantilever cap beam adopts a falling type steel pipe Bailey beam support, and the top of the support frame is horizontal.

[0062] After the optimization of the slope of the large cantilever cap beam, the elevation of the support frame is determined according to the design elevation of the large cantilever cap beam and the height of the steel formwork, which is simple to operate and easy to standardize the construction of the gradually changing slope.

[0063] The large cantilever cap beam formwork structure with a gradually changing slope of the present application optimizes the slope value of the large cantilever cap beam, and greatly reduces the types of the slope value of the cap beam by slightly adjusting the height of the cushion stone to optimize the error.

[0064] The large cantilever cap beam formwork structure with a gradually changing slope of the present application ensures that the large cantilever cap beam with an S curve pier cap has a misalignment of not more than 5mm at the joint between the pier and the cap beam under the change of the slope value, and improves the construction quality and the sensory effect.

[0065] In the case of road construction across the road without changing the transition, the large cantilever cap beam formwork structure with gradual transverse slope of the present application is divided into blocks as a whole for convenient hoisting and dismounting, thereby ensuring smooth and safe traffic.

[0066] The large cantilever cap beam formwork structure with gradual transverse slope of the present application adopts large cantilever cap beam formwork to replace the turning module and the slope starting support, thereby realizing the rapid strain of the transverse slope of the large cantilever cap beam, improving the utilization rate of the formwork, and saving the cost.

It should be understood by those skilled in the art that the scope of the application involved in the present application is not limited to the technical solutions formed by the specific combinations of the above technical features, and also covers other technical solutions formed by any combination of the above technical features or equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) having similar functions to form technical solutions.
