Description
Technical Field
[0001] The utility model relates to the technical field of bridge engineering construction, in particular to an adjustable cylindrical pier tie beam template structure. Background Art
[0002] With China's reform and opening up and urbanization, my country's transportation infrastructure construction has achieved remarkable achievements. Roads have been built through mountains and bridges have been built across rivers, and the world's largest high-speed railway network and expressway network have been built. With the increasing scale of construction, there are more and more bridges such as highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, and flyovers. The bridges are getting higher and longer, and higher piers are needed to support them. It is very common to set tie beams on piers to ensure structural safety. The most critical preparation for tie beam construction is the processing and production of templates. Traditional customized templates can only be used for one type of tie beam, but as the height of the pier changes, the width and / or height of the tie beam of the pier with the same diameter may change. The traditional customized template has poor adaptability, long processing cycle, and low turnover utilization rate, which cannot meet the construction requirements. Therefore, an adjustable cylindrical pier tie beam template structure is urgently needed. Utility Model Content
[0003] The utility model provides an adjustable cylindrical pier tie beam template structure to solve the technical problems of poor adaptability, long processing cycle and low turnover utilization rate of traditional bridge pier tie beam templates.
[0004] The utility model is realized by adopting the following technical scheme: an adjustable cylindrical pier tie beam template structure, comprising a template frame surrounded by a semicircular segment template, an adjustable segment template, an end connecting segment template, and a straight segment flat template. The adjustable segment template is an arc-shaped template connected to the two ends of the semicircular segment template, the end connecting segment template is a flat template, one end of which is connected to the adjustable segment template, and the other end is connected to the straight segment flat template. Ribs are arranged horizontally and vertically on the outer side of each template. The ribs at the connection of each template are connecting plates. Connecting holes are arranged on the connecting plates. Bolts are inserted into the connecting holes to fix adjacent templates with nuts. A plurality of tie rod fixing grooves for fixing tie rods are arranged horizontally and symmetrically on the outer sides of the ribs of the end connecting segment template and the straight segment flat template.
[0005] Furthermore, the straight segment flat template is formed by combining and splicing a plurality of sections.
[0006] Furthermore, the ribs at the upper and lower edges of each template are connecting plates, and connecting holes are provided on the connecting plates, which can be fixed by bolts and nuts to increase the height of the template frame.
[0007] Furthermore, the pull rod fixing slot is composed of two channel steels which are back to back.
[0008] The utility model discloses an adjustable cylindrical pier tie beam template structure, which can adapt to tie beams of the same diameter but different widths, thereby increasing the turnover times and reducing the template production cycle. It transforms the traditional customized tie beam template in construction into a freely adjustable optional structure, and is an economical and efficient template structure.
[0009] Compared with the traditional method of making fixed formwork, it has high flexibility, strong applicability, many turnover times and short production cycle, which greatly reduces the construction cost. When the width of the tie beam changes, only the adjustable section of the formwork needs to be replaced and reconnected for matching use. When the height of the tie beam changes, only the templates need to be raised and connected for matching use. No customization is required, and it has extremely wide promotion value.

[0019] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an adjustable cylindrical pier tie beam template structure of the utility model in conjunction with the accompanying drawings.
[0020] like Figure 1 to Figure 8As shown, an adjustable cylindrical pier tie beam formwork structure includes a formwork frame composed of a semicircular segment formwork 1, an adjustable segment formwork 2, an end connecting segment formwork 3, and a straight segment flat formwork 4. The adjustable segment formwork 2 is an arc-shaped formwork connected to both ends of the semicircular segment formwork 1. The end connecting segment formwork 3 is a flat formwork, one end of which is connected to the adjustable segment formwork 2, and the other end is connected to the straight segment flat formwork 4. Ribs 5 are arranged horizontally and vertically on the outer side surface of each formwork. The ribs 5 at the connection of each formwork are connecting plates 6. Connecting holes 7 are arranged on the connecting plates 6. Bolts are inserted into the connecting holes 7 to fix adjacent formworks with nuts. A plurality of tie rod fixing slots 8 for fixing tie rods are arranged horizontally and symmetrically between the end connecting segment formwork 3 and the straight segment flat formwork 4.
[0021] Semicircular segment templates 1 are made of two per set and are bent from 5mm thick steel plates, with an inner diameter equal to the diameter of the pier column. The arc length of the adjustable segment template 2 is determined based on the width of the tie beam. It is bent from 5mm thick steel plates, with the same arc as the pier column. Each group is divided into two types, two of each type, and several groups are configured according to the width of the tie beam. The end connection segment template 3 is cut from 5mm thick steel plates, with four per set, divided into two types; the straight segment flat template 4 uses a combined steel template, and the number of configurations is determined according to the length of the tie beam.
[0022] The ribs 5 are divided into two types: arc-shaped and straight-line types. They are made of 5mm thick steel plates and connected to the template by welding. Ribs are set in the longitudinal and transverse directions of the arc segment, with a rib width of 7cm, a transverse spacing of 30cm, and a longitudinal spacing of 20cm; transverse ribs are set in the straight segment, with a rib width of 5cm and a spacing of 30cm; the end ribs on both sides of each section of the template are connecting plates 6, with holes punched as installation ports for assembly bolts, with a spacing of 10cm; the top and bottom ribs of the template can also be connecting plates 6, with holes punched as installation ports for upper and lower layer connection bolts, with a spacing of 20cm.
[0023] The tie rod fixing slot 8 is composed of two channel steels back to back, with a 2~3cm spacing between the channel steels for inserting the tie rod, and the height of the channel steel is 15~20cm higher than the template; the tie rod fixing slot 8 is welded and fixed perpendicular to the direction of the transverse rib, and is respectively set at the center of the end connection section and the center of each straight section standard block.
