Description
Technical Field
[0001] This invention relates to the field of large-scale concrete construction formwork climbing scaffolding systems, and in particular to a multi-dimensional adjustable climbing scaffolding system and construction method for non-removable precast concrete insulated formwork suitable for environments with large temperature differences. Background Technology
[0002] Climbing formwork systems are an important formwork system used in the construction of vertical concrete structures. Due to their advantages such as high load-bearing capacity, fast construction speed, simple operation, and provision of a working platform for construction workers, climbing formwork systems have been widely used in the construction of various vertical concrete structures, including hydropower stations, bridge towers, and high-rise buildings. In the project area involved in this invention, where temperature differences are significant, a new type of precast concrete insulated formwork is used, with staggered joint construction as the primary method on site. The precast concrete formwork is connected by bolts, and diagonal tie rods are installed inside the formwork. Figure 6 As shown, the climbing formwork is installed on embedded cones pre-embedded in the precast concrete formwork. After the Nth pouring layer is completed, the climbing formwork is raised from the N-1 layer to the Nth layer. The positions of the two embedded cones are not in the same vertical direction, and the position of the formwork changes. The support position of the precast concrete formwork also changes with the position of the formwork. Traditional climbing formwork systems have the following problems for the construction of precast concrete insulation formwork projects: 1. Traditional climbing formwork systems cannot be applied to the staggered joint construction process of precast concrete insulation formwork; 2. Traditional climbing formwork systems cannot adapt to the construction of hyperbolic shapes; 3. Traditional climbing formwork cannot provide support and temporary reinforcement for precast concrete insulation formwork during structural construction. The content described in the background section of this invention is not an admission of prior art, but only to more easily illustrate the existing technical difficulties. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a multi-dimensional adjustable climbing frame system and construction method for precast concrete insulation formwork that does not require dismantling, which can be conveniently used for the construction of precast concrete formwork for staggered joint structures, and is easy and quick to operate.
[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-dimensional adjustable climbing frame system for precast concrete insulation formwork that does not require dismantling, wherein the formwork side of the main load-bearing triangular frame is provided with a main triangular frame anchor seat, which is used to connect with the anchoring system embedded in the precast concrete formwork. The main load-bearing triangular frames are fixedly connected by the platform main beam and connecting beam with an adjustable distance. The main beam of the platform of the main load-bearing triangular frame is equipped with a shaft connection support, and one end of the shaft connection support is hinged to the lower shaft of the template connection and the upper shaft of the template connection. The other ends of the lower shaft and the upper shaft of the template connection are respectively hinged to the shaft anchor seat, which is used to connect to the anchoring system.
[0005] In a preferred embodiment, the anchoring system is set up in two rows and multiple columns on each precast concrete formwork. The upper row of anchoring systems is connected to the main triangular frame anchor and the shaft anchor, and the lower row of anchoring systems is connected to the main triangular frame anchor.

[0006] In a preferred embodiment, the anchoring system is arranged in 2 rows and 3 columns on each precast concrete formwork, with one column of anchoring system located at the edge of the precast concrete formwork and the other columns of anchoring system located in the middle of the precast concrete formwork.

[0008] In the preferred embodiment, the anchoring system of the precast concrete formwork of the poured layer is connected to the main tripod anchoring seat; The anchoring system of the precast concrete formwork for the next pouring layer corresponds to the position of the shaft anchor seat.
[0009] In a preferred embodiment, the anchoring system includes a pre-embedded cone, which is embedded in the precast concrete formwork. The pre-embedded cone has an internal thread, and the opening of the internal thread faces the outer surface of the precast concrete formwork. The shaft anchor seat and the main triangular frame anchor seat are equipped with connecting plates, and the climbing cone bolts pass through the connecting plates and are connected to the pre-embedded tapered threads.
[0010] In the preferred embodiment, radially arranged anchor rods are fixed on the pre-embedded cone.
[0011] In the preferred embodiment, the main tripod anchor is located near the top of the main load-bearing tripod. The connecting plate of the main tripod anchor has a downward-facing "U"-shaped groove. Reinforcing structures are provided on both sides of the "U"-shaped groove. The safety pin passes through the reinforcing structure and locks the end of the climbing cone bolt in the "U"-shaped groove, so that the main load-bearing tripod can be quickly hung on the climbing cone bolt after being lifted and is prevented from falling off by the safety pin.
[0012] In the preferred embodiment, the main load-bearing triangular frame is structured such that the bottom of the horizontal bar of the main triangular frame near the precast concrete formwork is hinged to the top of the vertical bar of the main triangular frame, and the vertical bar of the main triangular frame is provided with a main triangular frame anchor seat near the top and a support near the bottom. One end of the main tripod axle is hinged to the bottom of the main tripod horizontal bar away from the template, and the other end is hinged to the main tripod vertical bar. The main tripod horizontal bar, the main tripod axle, and the main tripod vertical bar form a stable load-bearing triangular structure.

Detailed Implementation
[0031] Example 1: like Figure 1 , 2 In the present invention, a multi-dimensional adjustable climbing frame system for precast concrete insulation formwork that does not require dismantling is provided. The main load-bearing triangular frame 1 is provided with a main triangular frame anchor seat 1-5 on the formwork side. The main triangular frame anchor seat 1-5 is used to connect with the anchoring system 5 embedded in the precast concrete formwork 8. Preferred solutions include Figure 5 In the process, the anchoring system 5 includes a pre-embedded cone 5-4, which is pre-embedded in the precast concrete formwork 8. The pre-embedded cone 5-4 is provided with internal threads, and the opening of the internal threads faces the outer surface of the precast concrete formwork 8. The shaft anchor seat 6 and the main triangular frame anchor seat 1-5 are equipped with connecting plates, and the climbing cone bolt 5-3 passes through the connecting plate and is threadedly connected to the pre-embedded cone 5-4.
[0032] Preferred solutions include Figure 5 In this system, radially arranged anchor rods 5-5 are fixed on the pre-embedded cone 5-4. Preferably, the anchor rods 5-5 are threadedly connected to the pre-embedded cone 5-4 via bolts, and the anchor rods 5-5 and bolts have a cross-shaped structure. The anchor rods 5-5 and bolts are cast into the concrete within the chamber to improve the load-bearing capacity of the anchoring system 5.
[0033] like Figure 6 In the middle, the main load-bearing triangular frames 1 are fixedly connected by the platform main beams 1-4 and the connecting beams in an adjustable manner; like Figure 1 In the middle, the platform main beam 1-4 of the main load-bearing triangular frame 1 is provided with a shaft connecting support 4-3, which is hinged to one end of the lower shaft 4-1 of the template connection and the upper shaft 4-2 of the template connection; like Figure 1 In the middle, the other ends of the lower shaft 4-1 and the upper shaft 4-2 of the template connection are respectively hinged to the shaft anchor seat 6, which is used to connect with the anchoring system 5. The shaft anchor seat 6 is provided with a through hole to facilitate the passage of the climbing tapered bolt 5-3 to connect with the pre-embedded cone 5-4.
[0034] Preferred solutions include Figure 3 , 4 In this process, the anchoring system 5 is set up in multiple rows and columns on each precast concrete template 8. The upper row of anchoring systems 5 is connected to the main triangular frame anchor seat 1-5 and the shaft anchor seat 6, and the lower row of anchoring systems 5 is connected to the main triangular frame anchor seat 1-5. The spacing n between adjacent anchoring systems 5 is equal, so that the staggered spacing between adjacent rows of precast concrete formwork 8 is n or a multiple of n, and only the climbing formwork system needs to be lifted directly during construction.
[0035] Preferred solutions include Figure 3 , 4 In this process, the anchoring system 5 is set in 2 rows and multiple columns on each precast concrete formwork 8. The upper row of anchoring systems 5 is connected to the main triangular frame anchoring seat 1-5 and the shaft anchoring seat 6, and the lower row of anchoring systems 5 is connected to the main triangular frame anchoring seat 1-5. The spacing n between adjacent anchoring systems 5 is equal, so that the staggered spacing between adjacent rows of precast concrete formwork 8 is n or a multiple of n, allowing the climbing frame system to be lifted directly upwards during construction without the need for lateral adjustment.
[0036] Preferred solutions include Figure 3 , 4 In this design, the anchoring system 5 is arranged in 2 rows and 3 columns on each precast concrete formwork 8, with one column of anchoring system 5 located at the edge of the precast concrete formwork 8 and the other columns located in the middle of the precast concrete formwork 8. This structure allows for direct lifting of the entire climbing scaffold system with staggered joints in the precast concrete formwork 8, reducing the time required for adjusting and positioning the climbing scaffold system and improving construction efficiency. Furthermore, the staggered arrangement of the precast concrete formwork 8 enhances the strength of the vertical formwork structure that does not require dismantling.
[0037] Preferred solutions include Figure 1 In the middle, the main load-bearing triangular frame 1, the shaft connecting support 4-3, the lower shaft 4-1 connecting to the formwork, and the upper shaft 4-2 connecting to the formwork are arranged in multiple groups along the horizontal direction, and the groups are fixedly connected by connecting beams; in Figure 6For ease of observation, the structure of the connecting beams is omitted. Preferably, the connecting beams are fixedly connected to each climbing frame assembly, i.e., each climbing frame unit, in an adjustable manner, such as using fasteners, to improve stability and adaptability to dam curvature adjustments. The platform main beams 1-4 are arranged in multiple sets in the vertical direction of the main load-bearing triangular frame 1 to improve the rigidity of the entire climbing frame system.
[0038] like Figure 6 In the middle, the precast concrete formwork 8 in adjacent rows are arranged in an alternating manner, with an alternation interval of n or a multiple of n.
[0039] Preferred solutions include Figure 6 In the middle, the anchoring system 5 of the precast concrete formwork 8 of the poured layer is connected to the main tripod anchoring seat 1-5; The anchoring system 5 of the precast concrete formwork 8 for the next pouring layer corresponds to the position of the shaft anchoring seat 6.
[0040] Preferred solutions include Figure 1 , 4 In the middle, the main tripod anchor 1-5 is located near the top of the main load-bearing tripod 1. The connecting plate of the main tripod anchor 1-5 has a downward-facing "U" shaped groove. There are reinforcing structures on both sides of the "U" shaped groove. The reinforcing structures are made of channel steel or I-beams. The safety pin 1-6 passes through the reinforcing structure and locks the end of the climbing cone bolt 5-3 in the "U" shaped groove so that the main load-bearing tripod 1 can be quickly hung on the climbing cone bolt 5-3 after being lifted, and the safety pin 1-6 is inserted to prevent the entire main load-bearing tripod 1 from falling off.
[0041] Preferred solutions include Figure 1 In the middle, the structure of the main load-bearing triangular frame 1 is as follows: the bottom of the horizontal bar 1-1 of the main triangular frame near the precast concrete formwork is hinged to the top of the vertical bar 1-2 of the main triangular frame. The vertical bar 1-2 of the main triangular frame is provided with a main triangular frame anchor 1-5 near the top and a support near the bottom. The support mainly bears the pressure and supports the surface of the precast concrete formwork 8. One end of the main triangular frame shaft 1-3 is hinged to the bottom of the main triangular frame horizontal bar 1-1 away from the template, and the other end is hinged to the main triangular frame vertical bar 1-2. The main triangular frame horizontal bar 1-1, the main triangular frame shaft 1-3 and the main triangular frame vertical bar 1-2 form a stable load-bearing triangular structure. The shaft connection support 4-3 is located on the main beam 1-4 of the platform, near the main triangular frame shaft 1-3. This structure improves the stiffness and stability of the load-bearing structure.
[0042] Preferred solutions include Figure 1 , 2In the middle, the bottom of the main load-bearing triangular frame 1 is connected to the lower platform frame assembly 3; the lower platform frame assembly 3 consists of the lower platform front suspension rod 3-1, the lower platform rear suspension rod 3-2 and the lower platform horizontal rod 3-3, and the lower platform main beam 3-4 is laid on the lower platform horizontal rod 3-3.
[0043] The top of the main load-bearing tripod 1 is connected to the upper platform frame assembly 2; as follows Figure 1 In the middle, the upper platform frame assembly 2 includes two upper platform uprights 2-1. The bottom of the two upper platform uprights 2-1 is connected to the platform main beam 1-4 at the top of the main triangular frame horizontal bar 1-1 via upper platform connecting supports 2-4. An upper platform axle 2-5 is provided between the two upper platform uprights 2-1. The upper platform horizontal bar 2-2 is connected to the two upper platform uprights 2-1. An upper platform main beam 2-6 and an upper platform railing 2-3 are provided on the upper platform horizontal bar 2-2. The levelness of the upper platform main beam 2-6 can be adjusted through the upper platform axle 2-5, making it convenient for workers to stand during construction.
[0044] Preferred solutions include Figure 1 , 2 In the design, the upper platform shaft 2-5, the main tripod shaft 1-3, the lower template connecting shaft 4-1, and the upper template connecting shaft 4-2 are all adjustable in length and self-locking. Preferably, the shafts adopt a screw sleeve structure, with screws at both ends of the shaft. The two screws have opposite thread directions, and the two screws are connected to a threaded sleeve in the middle. The length of the entire shaft is adjusted by rotating the threaded sleeve and locked by a nut.
[0045] Example 2: like Figure 3 , 6 A construction method using the aforementioned multi-dimensional adjustable climbing scaffold system for non-removable precast concrete insulation formwork includes the following steps: S1, the shaft anchoring seat 6 of the lower shaft 4-1 and the upper shaft 4-2 of the template connection is connected to the anchoring system 5 of the precast concrete template 8 of the N+1th layer, and the main triangular frame anchoring seat 1-5 of the main load-bearing triangular frame 1 is connected to the anchoring system 5 of the precast concrete template 8 of the Nth layer. When pouring the first layer, the shaft connecting support 4-3 is fixed to the ground by ground anchor bolts. The lower shaft connecting the formwork 4-1 and the upper shaft connecting the formwork 4-2 are installed at the formwork support point 5-1 of the precast concrete formwork 8. The verticality of the formwork is adjusted and the formwork is erected. S2. After the first layer of concrete is poured and initially set, install the climbing bolts 5-3 at the anchor point 5-2 of the precast concrete formwork 8, hoist the main load-bearing triangular frame 1, install the formwork connection support shaft system 4, and install the second layer of precast concrete formwork 8. Before hoisting the second layer of precast concrete formwork 8, install the shaft anchor seat 6 on the formwork support point 5-1. The second layer of precast concrete formwork 8 and the first layer of precast concrete formwork 8 are staggered, and the formwork connection support shaft system 4 is hinged to the main triangular frame anchor seat 1-5. S3. Pour the second layer of concrete. After initial setting, remove safety pins 1-6, separate the shaft anchor seat 6 from the anchoring system 5, and remove the main triangular frame anchor seat 1-5 on the precast concrete formwork 8 of the second layer. In this example, initial setting refers to the condition that the concrete reaches the demolding strength after setting.
[0046] S4. Lift the entire climbing formwork system to the height of one section. In this example, the height of one section usually refers to the height of a row of precast concrete insulation formwork that does not need to be dismantled. The lifting is carried out by a lifting device arranged on the temporary dam top. Since the present invention adopts a lightweight design scheme, the structure of the existing climbing formwork system is greatly simplified without affecting the function, thus greatly reducing the lifting weight requirement. Realign and connect the main triangular anchor seat 1-5 of the main load-bearing triangular frame 1 with the anchoring system 5 of the second section of precast concrete formwork 8, and connect the formwork connecting support shaft system 4 with the anchoring system 5 of the third section of precast concrete formwork 8. S5. Pour the third layer of concrete, repeat steps S3 to S4, and so on, to complete the concrete pouring of each section without dismantling the precast concrete insulation formwork and climbing frame system.
[0047] Preferred solutions include Figure 1 In the process of adjusting the lengths of the lower template connecting shaft 4-1 and the upper template connecting shaft 4-2 in the template connecting support shaft system 4, the precast concrete templates 8 of each compartment are made to conform to the surface curvature of the concrete structure. That is, different included angles can be set between the rows of non-removable precast concrete insulation templates; the working surfaces of adjacent non-removable precast concrete insulation templates in the same row can not be a straight line, but rather a fitted curve that matches the horizontal curve of the dam. Similarly, the working surfaces between rows of non-removable precast concrete insulation templates in the vertical direction can not be a straight line, but rather a fitted vertical curve of the dam. This advantage allows for convenient application in the pouring and construction of hyperbolic arch dams.
[0048] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The embodiments and features described in these embodiments can be arbitrarily combined without conflict. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
