Therefore, they cannot be understood as limiting the present invention.

[0032] As introduced in the background technology, during the current independent column construction, the templates and secondary back ribs need to be assembled separately and disassembled repeatedly, and a scaffolding needs to be built around each column, which greatly increases the construction time. To address the above problems, this application proposes a template for independent column construction.

[0033] In a typical embodiment of the present application, Figures 1-6 As shown, a template for independent column construction includes a template body 1. The template body can adopt the structure of the existing independent column construction template, which is a rectangular plate body. The outer side surface of the template body is provided with multiple secondary back ribs 2. The multiple secondary back ribs are arranged in parallel, and the secondary back ribs are arranged parallel to the length direction of the template body.

[0034] Preferably, the secondary back rib adopts a U-shaped structure, including a first back rib portion 2-1 and a second back rib portion 2-2 integrally arranged on both sides of the first back rib portion, one end of the second back rib portion is integrally connected to the first back rib portion, and the other end is provided with a connecting portion 2-3, which is provided with multiple mounting holes, and the secondary back rib is detachably fixed to the template body through the mounting holes and screws.

[0035] In some other embodiments, the secondary back ribs may also be fixedly connected to the outer side surface of the template body by welding.

[0036] It is understandable that the secondary back ribs may also adopt other structural forms, as long as they can be fixedly connected to the outer side of the template body and their outer side has a plane for connecting to the reinforcement. Those skilled in the art can make a choice according to actual needs.

[0037] When the height of the template body is high, the secondary back rib is composed of multiple secondary back rib segments. In this embodiment, the secondary back rib is composed of two secondary back rib segments, and the end of one secondary back rib segment is provided with a plug-in portion, and the plug-in portion of the secondary back rib segment is inserted into the end of the other secondary back rib segment, and the plug-in portion and the end of the other secondary back rib segment are provided with matching plug-in holes, and a fixing piece is inserted into the plug-in hole for plugging and fixing two adjacent secondary back rib segments. Preferably, the fixing piece is an arc-shaped iron sheet 3, which is not easy to fall out of the plug-in hole after being inserted into the plug-in hole.

[0038] In this embodiment, a plurality of reinforcing members are fixed to the outer side surface of the first back rib portion, the plurality of reinforcing members are arranged in parallel, and the reinforcing members are arranged perpendicular to the secondary back rib portion. The reinforcing member includes a fixed portion 4 and a telescopic portion 5 arranged at one end of the fixed portion, and the telescopic portion is telescopically connected to the fixed portion.

[0039] The fixing portion includes a first reinforcing beam 4-1 and a second reinforcing beam 4-2 arranged in parallel, with a set distance between the first reinforcing beam and the second reinforcing beam. The first reinforcing beam and the second reinforcing beam are connected and fixed by a connecting plate 4-3. Preferably, the first reinforcing beam and the second reinforcing beam are both made of channel steel.

[0040] A plurality of fixing plates 6 are fixed to the outer side surfaces of the first reinforcement beam and the second reinforcement beam. In this embodiment, two fixing plates are provided, and the number of fixing plates can be set according to actual needs.

[0041] A screw passes through the fixing plate, and the screw is threadedly connected to a nut fixed to the primary back rib. The other end of the screw is threadedly connected to a fixing nut 7 pressed against the fixing plate, thereby realizing detachable fixation of the reinforcement and the secondary back rib. Preferably, the nut is fixedly connected to the primary back rib by welding.

[0042] It is understandable that the first reinforcement beam and the second reinforcement beam can also be directly detachably fixed to the first back rib portion of the secondary back rib by bolts or other fixing methods with the secondary back rib can be selected. Those skilled in the art can make settings according to actual needs.

[0043] A telescopic portion is provided at one end of the fixed portion, and the telescopic portion is telescopically connected to the fixed portion. Preferably, the telescopic portion is provided at the end of the gap between the first reinforcement beam and the second reinforcement beam, and can move in the gap between the first reinforcement beam and the second reinforcement beam along the length direction of the first reinforcement beam and the second reinforcement beam.

[0044] A baffle 5-1 is provided at the inner end of the telescopic part, and a first limiting plate 4-4 and a second limiting plate 4-5 are provided at the end gaps of the telescopic part provided by the first reinforcement beam and the second reinforcement beam. The movement of the telescopic part can make the baffle contact with the first limiting plate and the second limiting plate, thereby limiting the movement of the telescopic part, preventing the telescopic part from falling from the fixed part and the telescopic part from being retracted into the fixed part.

[0045] In this embodiment, the first limiting plate is arranged at the ends of the first reinforcing beam and the second reinforcing beam, and two first limiting plates are provided. The two first limiting plates are arranged on both sides of the space between the first reinforcing beam and the second reinforcing beam, and can contact the two side edges of the baffle without hindering the extension of the telescopic part. The second limiting plate covers the cross-section of the gap between the first reinforcing beam and the second reinforcing beam, and can contact the baffle to limit the position of the telescopic part retracting into the fixed part. At the same time, the second limiting plate also acts as a connecting plate, so that the first reinforcing beam and the second reinforcing beam are fixed.

[0046] In some other embodiments, the fixed part may also be an integral beam with a slide groove provided at its end, and the telescopic part is telescopically connected to the fixed part through the slide groove. Those skilled in the art may make settings according to actual needs, which will not be described in detail here.

[0047] The telescopic portion at one end of the first reinforcement beam and the second reinforcement beam is provided with a first limiting hole 8, and the other end of the first reinforcement beam and the second reinforcement beam is provided with a plurality of second limiting holes 9, into which limiting members can be inserted.

[0048] Preferably, the first limiting hole and the second limiting hole are rectangular holes, and the limiting member is an inclined iron 10 with a larger width at one end and a smaller width at the other end. The inclined iron can be inserted into the first limiting hole and the second limiting hole, and the end of the inclined iron with a larger width is located at the top. The limiting member is an inclined iron, and can utilize the shape of the inclined iron and the coordinated effect of the inclined iron's own gravity to achieve fixation in the limiting hole. There is no need to set up other locking structures, and the implementation method is simple and quick.

[0049] It is understandable that the limiting holes may also be round holes, and the limiting members may be limiting bolts and limiting nuts, which may also achieve the same function. Those skilled in the art may make settings according to actual needs.

[0050] A plurality of second limiting holes are provided to meet the use requirements of reinforcement pieces of different widths.

[0051] The ends of the telescopic parts of the first and second reinforcing beams are also provided with rectangular holes. After the telescopic part is received in the fixed part, the oblique iron can be inserted into the rectangular hole and the first limiting hole to achieve locking and fixation of the telescopic part after it is received in the fixed part.

[0052] Example 2:

[0053] This embodiment discloses a template system for independent column construction, which is used for the pouring construction of square columns. Figure 7-Figure 8 As shown, it includes four independent column construction templates described in Example 1, and the four independent column construction templates described in Example 1 enclose a rectangular space as a casting space for the independent column.

[0054] In the two adjacent first independent column construction formwork and second independent column construction formwork arranged at 90°, the telescopic part of the reinforcement of the first independent column construction formwork extends out of the fixed part and passes through the gap between the first reinforcement beam and the second reinforcement beam of the second independent column construction formwork to pass through the fixed part end of the second independent column construction formwork. The first limiting piece is inserted into the first limiting hole of the telescopic part of the first independent column construction formwork, and the first limiting piece is located on the outside of the reinforcement of the second independent column construction formwork. The second limiting piece is inserted into the second limiting hole at the fixed part end of the second independent column construction formwork, and the second limiting piece is located on the outside of the telescopic part of the first independent column construction formwork. The first limiting piece and the second limiting piece are used to complete the limiting fixation of the reinforcements of the two adjacent independent column construction formworks. The same method is used to sequentially limit and fix the reinforcements of the adjacent independent column construction formworks to complete the limiting fixation of the four independent column construction formworks.

[0055] Example 3:

[0056] This embodiment discloses a construction method of the formwork system for independent column construction described in Example 2, comprising the following steps:

[0057] Step 1: Assemble the formwork body, secondary back ribs and reinforcement parts of the four independent column construction formwork in advance.

[0058] Specifically, the template body is cut into the required size for installation, and the secondary back ribs are fixed to the template body with screws according to the design drawings. Preferably, the screws are drilled in at an angle, and the reinforcement is fixed to the secondary back ribs using screws and nuts.

[0059] Step 2: Hoist the four independent column construction templates so that the four independent column construction templates enclose a square space for pouring the independent columns.

[0060] Step 3: Among the two adjacent independent column construction formworks that are at 90° angles, extend the telescopic part of one of the independent column construction formworks and pass it through the end of the fixed part of the other independent column construction formwork, and insert the oblique iron, and insert the oblique iron into the end of the fixed part of the other independent column construction formwork to complete the splicing of the two adjacent independent column construction formworks. Use the same method to complete the splicing of the four independent column construction formworks in sequence. After the splicing is completed, the construction of the independent column construction formwork system is completed.

[0061] After the templates are spliced, the independent columns are poured. After the pouring is completed, the inclined iron is removed, the four independent column construction templates are separated and stored for the next pouring.

[0062] By adopting the construction method of this embodiment, the templates for independent column construction are pre-assembled. When in use, the entire template system is assembled at one time by the templates for independent column construction. The templates for independent column construction can be used repeatedly without disassembling into separate individual parts, which greatly improves the installation quality and efficiency of the square column templates, improves construction safety and site cleanliness, shortens the construction period, and reduces labor costs.

[0063] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
