Description

Technical Field

[0001] This invention relates to the field of reverse construction technology, and in particular to a reverse construction sidewall formwork. Background Technology

[0002] In modern construction, the reverse construction method is a method of excavating layer by layer downwards from the ground while simultaneously constructing the structure. Its advantages include the effective use of underground space and reduced impact on the surrounding environment. During reverse construction, the installation and securing of the sidewall formwork is crucial. Current reverse construction methods often use a triangular support structure at the bottom of the formwork (such as patent CN112709217B), using a triangular frame welded from steel pipes or structural steel to firmly fix the formwork to the ground. In the initial stages, when the excavation depth is shallow and the load on the formwork is relatively small, this support method can still meet stability requirements.

[0003] However, as the excavation depth increases, uncertainties in ground conditions, such as soft soil and high groundwater levels, may cause the triangular support structure to sink or tilt, resulting in insufficient overall stability of the formwork. This can lead to problems such as swaying or shifting, affecting the accuracy and quality of concrete pouring, and even posing a threat to the safety of the construction site. Summary of the Invention

[0004] The purpose of this invention is to provide a reverse construction method for sidewall formwork to solve the problem that existing sidewall formwork may have insufficient stability due to relying solely on the triangular support structure at the bottom for fixation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A reverse-construction sidewall formwork includes: a formwork body and a first support assembly, the first support assembly being installed at the bottom of the formwork body and used to tilt and support the formwork body on the ground; the formwork body is capable of forming a cavity with the rock wall, the cavity being used to fill with castable refractory; and a second support assembly, the second support assembly being installed at the top of the formwork body and used to be fixedly connected to the solidified castable refractory located on the upper layer of the formwork body, so that the top of the formwork body is fixed on the solidified castable refractory.

[0007] Based on the aforementioned technical means, this invention achieves comprehensive and stable support for the formwork body through two sets of upper and lower support components, thus solving the problem of insufficient stability that may exist in existing side wall formworks that rely solely on the triangular support structure at the bottom for fixation. This invention not only provides a first support component at the bottom of the formwork body for inclined support, ensuring the formwork stands stably on the ground, but also adds a second support component at the top of the formwork body. During the reverse construction method of layer-by-layer pouring, the formwork body of the layer being constructed can be fixedly connected to the solidified mortar of the previous layer through the second support component at the top, thereby achieving a firm fixation of the top of the formwork body.

[0008] Through the coordinated action of the upper and lower support components, the side wall formwork of this reverse construction method can maintain its original position and shape even when encountering large pressure or vibration during the pouring process, effectively avoiding problems such as formwork deformation or displacement. This not only improves construction efficiency but also ensures that the pouring material can be filled into the cavity evenly and accurately, providing a strong guarantee for the quality of subsequent projects.

[0009] Furthermore, the first support assembly includes a first support rod and a second support rod. One end of the first support rod is rotatably mounted on the template body, and the other end is supported on the ground to keep the template body tilted. The second support rod is located below the first support rod, and one end of the second support rod is rotatably mounted on the template body, while the other end is fixed to the ground.

[0010] Based on the aforementioned technical means, the combined design of the first and second support rods in this invention provides dual support for the template body. The first support rod is rotatably mounted on the template body at one end, while the other end is supported on the ground, allowing the template body to maintain the required tilt angle. The second support rod is located below the first support rod, also rotatably mounted on the template body at one end, with the other end fixed to the ground, further enhancing the stability and support force of the template body. This dual-support structure effectively disperses the pressure on the template body during pouring, preventing deformation or displacement due to uneven stress, thereby ensuring uniform filling of the mortar and the accuracy of the structure.

[0011] The rotatable installation of both the first and second support rods allows the first support assembly to be quickly and easily opened to the required angle during operation, accommodating different tilt angles of the template body. Furthermore, after operation, both the first and second support rods can be retracted, making the template body more compact and lightweight when support is not needed, facilitating pushing, placing, and transporting operations, and simplifying template storage and management.

[0012] Furthermore, the first support assembly also includes a first rotating shaft, which is rotatably mounted on the template body. One end of the first support rod is connected to the first rotating shaft, so that one end of the first support rod is rotatably mounted on the template body.

[0013] Based on the aforementioned technical means, the first support rod can rotate around the first pivot axis, allowing for flexible adjustment of the position of the entire first support assembly on the template body. This increases the flexibility and adaptability of the template system, enabling it to adapt to different working environments and installation requirements. When the first support assembly is not needed, it can be folded or moved to a location that does not occupy too much space by rotating the first support rod, helping to optimize space utilization, especially in space-constrained scenarios.

[0014] Furthermore, the template body is provided with supporting stiffening ribs, and the first rotating shaft is rotatably mounted on the supporting stiffening ribs.

[0015] Based on the aforementioned technical methods, the supporting stiffening ribs, as a reinforcement component of the formwork body, can significantly improve the formwork's load-bearing capacity and resistance to deformation. Installing the first rotating shaft on the supporting stiffening ribs ensures that the formwork body remains stable during rotation and adjustment of the first support assembly, preventing swaying or deformation. By installing the first rotating shaft on the supporting stiffening ribs, the structural strength of the formwork body can be utilized more effectively, enabling the first support assembly to provide more stable and reliable support. This helps improve construction efficiency and reduces construction delays and safety issues caused by unstable supports.

[0016] Furthermore, the first support assembly also includes a second rotating shaft, which is rotatably mounted on the template body and located below the first rotating shaft; one end of the second support rod is connected to the second rotating shaft so that one end of the second support rod is rotatably mounted on the template body.

[0017] Based on the aforementioned technical means, by adding a second rotating shaft below the first rotating shaft and connecting it to a second support rod, a more stable support structure is formed. This design not only enhances the vertical support force of the template body but also improves its horizontal stability, ensuring that the template will not tilt or shift during construction. The introduction of the second rotating shaft allows the second support rod to also rotate around the shaft, increasing the flexibility of the first support component and enabling it to adapt to support requirements at different heights and angles. When adjusting the template position or carrying out construction, operators can more easily adjust the angle and position of the support rod.

[0018] Furthermore, the other end of the second support rod has a ground anchor hole, and the first support assembly also includes an anchor nail that can pass through the ground anchor hole to fix the other end of the second support rod to the ground.

[0019] By using the aforementioned technical methods, a more stable support structure is formed by fixing the other end of the second support rod to the ground with anchor bolts. This design significantly enhances the stability of the formwork itself and the structure above it, especially when subjected to large loads or external forces such as wind, effectively preventing the formwork from overturning or shifting. A stable support structure is an important guarantee for construction safety. Fixing the second support rod to the ground ensures that construction workers will not face safety risks due to the swaying or tilting of the formwork when working on it. At the same time, this also helps to reduce construction accidents caused by unstable supports.

[0020] Furthermore, a tie rod hole is formed at the top of the template body, and the second support component is a tie rod that can pass through the tie rod hole to fix the top of the template body onto the solidified cast-in-place material. The cast-in-place material includes concrete and vertical reinforcement bars, which are vertically arranged within the concrete, and one end of the vertical reinforcement bar can extend downward through the concrete. The tie rod can pass through the tie rod hole and be fixedly connected to one end of the vertical reinforcement bar to fix the top of the template body to the cast-in-place material.

[0021] Based on the aforementioned technical means, the connection strength between the formwork body and the castable material is significantly improved through the fixed connection of the tie rod and the vertical reinforcement, ensuring that the formwork will not shift or deform during the pouring process, thereby guaranteeing the shape and dimensional accuracy of the castable material. This invention uses tie rods as a second support component, simplifying the formwork fixing process. Construction workers can quickly pass the tie rods through the tie rod holes and fix them to the vertical reinforcement, thus saving significant installation time and labor costs. Simultaneously, this design also facilitates the disassembly and reuse of the formwork.

[0022] Furthermore, a tie rod hole stiffening rib is formed on the top of the template body, and the tie rod hole stiffening rib is located on the side of the tie rod hole.

[0023] Based on the aforementioned technical methods, the addition of stiffening ribs around the tie rod holes significantly enhances the structural strength of the formwork body around the tie rod holes. This helps prevent localized deformation or damage to the formwork when subjected to tie rod tension, thereby ensuring the overall stability and service life of the formwork. Simultaneously, the stiffening ribs provide a more robust support surface for the tie rods, enabling a more secure connection between the tie rods and the formwork body. This reduces the risk of loosening or detachment of the tie rods during stress, and improves the reliability of the connection between the formwork and the cast-in-place material.

[0024] Furthermore, it also includes a pouring guide plate, which is installed obliquely at the top of the template body; a groove is formed at the top of the template body, and the groove extends along the length direction of the template body; the groove is adapted to the pouring guide plate, the pouring guide plate is installed on the groove, and can move on the groove.

[0025] Based on the aforementioned technical methods, the pouring guide plate can guide the pouring material to be poured in a predetermined direction and path, thereby ensuring the orderliness and accuracy of the pouring process. This helps reduce problems such as grout leakage and air bubbles during pouring, improving the pouring quality. The design of the pouring guide plate and chute allows construction workers to more easily adjust the pouring direction without frequently moving formwork or repositioning the pouring point. This significantly saves construction time and labor costs, improving construction efficiency.

[0026] Furthermore, a first stiffening rib and a second stiffening rib are formed on the template body. The first stiffening rib and the second stiffening rib are intersecting and arranged, with the first stiffening rib extending along the length direction of the template body and the second stiffening rib extending along the height direction of the template body.

[0027] Based on the aforementioned technical means, the intersection of the first and second stiffening ribs forms a stable support network, significantly enhancing the structural strength of the formwork body in both length and height directions. The addition of the first and second stiffening ribs allows the formwork body to withstand greater loads, including the weight of the cast-in-place material, the pressure of construction equipment, and external factors such as wind. This helps prevent deformation or damage to the formwork during casting due to excessive stress, ensuring the accuracy and stability of the cast-in-place structure.

[0028] The beneficial effects achieved by this invention are as follows:

[0029] 1. This invention achieves comprehensive and stable support for the formwork body through two sets of upper and lower support components, solving the problem of insufficient stability that may exist in existing side wall formwork which relies solely on the triangular support structure at the bottom for fixation. This invention not only provides a first support component at the bottom of the formwork body for inclined support, ensuring the formwork stands stably on the ground, but also adds a second support component at the top of the formwork body. During the reverse construction method of layer-by-layer pouring, the formwork body of the layer being constructed can be fixedly connected to the solidified mortar of the previous layer through the second support component at the top, thus achieving a firm fixation of the top of the formwork body.

[0030] 2. Through the synergistic effect of the upper and lower sets of support components, the side wall formwork of this reverse construction method can maintain its original position and shape even when encountering large pressure or vibration during the pouring process. This effectively avoids problems such as formwork deformation or displacement, which not only improves construction efficiency, but also ensures that the pouring material can be filled into the cavity evenly and accurately, providing a strong guarantee for the quality of subsequent projects.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0050] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0051] like Figure 1As shown, this embodiment proposes a reverse construction sidewall formwork, including: a formwork body 1 and a first support component 2. The first support component 2 is installed at the bottom of the formwork body 1 and is used to tilt and support the formwork body 1 on the ground 3. The formwork body 1 can form a cavity 4 with the rock wall 8, and the cavity 4 is used to fill the castable material 5. The second support component 6 is installed at the top of the formwork body 1 and is used to fix and connect with the solidified castable material 5 located on the upper layer of the formwork body 1, so that the top of the formwork body 1 is fixed on the solidified castable material 5.

[0052] In the specific reverse construction method, the first layer of ground-level construction is carried out: after the shaft is excavated to the design elevation, the first support component 2 is installed at the bottom of the formwork body 1 and adjusted to a suitable inclination angle to ensure that the formwork body 1 can be stably supported on the ground 3 and form the required cavity 4 between it and the rock wall 8. The cavity 4 is then filled with mortar 5, carefully controlling the pouring speed and volume to ensure that the mortar 5 can evenly fill the entire cavity 4. After the mortar 5 has completely solidified, the formwork is removed to prepare for the next layer of construction.

[0053] like Figure 3 and Figure 4 As shown, construction proceeds layer by layer (second layer and above): After the previous layer of grout 5 has completely solidified, an excavator or other excavation equipment is used to excavate downwards to the design elevation, forming a new construction space. The first support component 2 is installed at the bottom of the formwork body 1 and adjusted to a suitable inclination angle to ensure that the formwork body 1 is at the same angle as the previous layer of grout 5. The second support component 6 is then installed at the top of the formwork body 1 and fixedly connected to the solidified grout 5. The new cavity 4 is filled with grout 5, and the above pouring process is repeated.

[0054] After the grout 5 has completely solidified, check the pouring quality and make repairs if necessary. Repeat the above steps, advancing layer by layer downwards until the designed depth is reached.

[0055] This embodiment achieves comprehensive and stable support for the template body 1 through two sets of upper and lower support components, solving the problem of insufficient stability that may exist in existing side wall templates that rely solely on the triangular support structure at the bottom for fixation. This embodiment not only provides inclined support to the bottom of the template body 1 with a first support component 2 to ensure the template stands stably on the ground 3, but also adds a second support component 6 at the top of the template body 1. During the reverse construction method of layer-by-layer pouring, the template body 1 of the layer being constructed can be fixedly connected to the solidified mortar 5 of the previous layer through the second support component 6 at the top, thus achieving a firm fixation of the top of the template body 1.

[0056] Through the coordinated action of the upper and lower support components, the side wall formwork of this reverse construction method can maintain its original position and shape even when encountering large pressure or vibration during the pouring process, effectively avoiding problems such as formwork deformation or displacement. This not only improves construction efficiency but also ensures that the pouring material can be filled into the cavity evenly and accurately, providing a strong guarantee for the quality of subsequent projects.

[0057] like Figure 3 and Figure 4 As shown, in this embodiment, a reverse-construction sidewall formwork also includes a sealing mesh 9. The sealing mesh 9 is connected to the bottom of the formwork body 1 and is laid under the pouring material 5 during the pouring process. It is used to isolate the contact between the ground soil layer 3 and the pouring material 5, reducing the contamination of the working surface. After the upper layer of pouring material 5 solidifies, the sealing mesh 9 of that layer is removed, increasing the roughness at the junction of the two layers, making the structure more integral, and effectively preventing water leakage. Preferably, in this embodiment, the sealing mesh 9 is made of galvanized material. Galvanized material has good corrosion resistance and rust prevention, which can maintain the integrity and functionality of the sealing mesh for a long time, further enhancing its protective effect on the pouring material.

[0058] like Figure 1 As shown, the first support assembly 2 includes a first support rod 21 and a second support rod 22. One end of the first support rod 21 is rotatably mounted on the template body 1, and the other end is supported on the ground 3 so that the template body 1 is kept tilted. The second support rod 22 is located below the first support rod 21, and one end of the second support rod 22 is rotatably mounted on the template body 1, and the other end is fixed on the ground 3.

[0059] like Figure 1 As shown, the combined design of the first support rod 21 and the second support rod 22 in this embodiment provides dual support for the template body 1. The first support rod 21 is rotatably mounted on the template body 1 at one end, while the other end is supported on the ground, allowing the template body 1 to maintain the required tilt angle. The second support rod 22 is located below the first support rod 21, also rotatably mounted on the template body 1 at one end, while the other end is fixed to the ground, further enhancing the stability and support force of the template body 1. This dual-support structure can effectively distribute the pressure on the template body 1 during the pouring process, preventing deformation or displacement of the template due to uneven stress, thereby ensuring the uniform filling of the mortar 5 and the accuracy of the structure.

[0060] The rotatable installation of both the first support rod 21 and the second support rod 22 allows the first support assembly 2 to be quickly and easily opened to the required angle during operation, accommodating the needs of the template body 1 at different tilt angles. Furthermore, after operation, both the first support rod 21 and the second support rod 22 can be retracted, making the template body 1 more compact and lightweight when support is not needed, facilitating pushing, placing, and transporting operations, and simplifying template storage and management.

[0061] like Figure 1 As shown, the first support assembly 2 also includes a first rotating shaft 23, which is rotatably mounted on the template body 1. One end of the first support rod 21 is connected to the first rotating shaft 23 so that one end of the first support rod 21 is rotatably mounted on the template body 1.

[0062] The design of the first pivot 23 allows the first support rod 21 to rotate around the pivot, enabling flexible adjustment of the position of the entire first support assembly 2 on the template body 1. This increases the flexibility and adaptability of the template system, allowing it to adapt to different working environments and installation requirements. When the first support assembly 2 is not needed, it can be folded or moved to a position that does not occupy too much space by rotating the first support rod 21, which helps optimize space utilization, especially in space-constrained scenarios.

[0063] like Figure 1 As shown, a support stiffening rib 11 is formed on the template body 1, and the first rotating shaft 23 is rotatably mounted on the support stiffening rib 11.

[0064] The stiffening rib 11, serving as a reinforcement of the formwork body 1, significantly improves the formwork's load-bearing capacity and resistance to deformation. Installing the first rotating shaft 23 on the stiffening rib 11 ensures that the formwork body 1 remains stable during rotation and adjustment of the first support assembly 2, preventing swaying or deformation. By installing the first rotating shaft 23 on the stiffening rib 11, the structural strength of the formwork body 1 can be utilized more effectively, enabling the first support assembly 2 to provide more stable and reliable support. This helps improve construction efficiency and reduces construction delays and safety issues caused by unstable support.

[0065] like Figure 1 As shown, the first support assembly 2 also includes a second rotating shaft 24, which is rotatably mounted on the template body 1 and is located below the first rotating shaft 23; one end of the second support rod 22 is connected to the second rotating shaft 24 so that one end of the second support rod 22 is rotatably mounted on the template body 1.

[0066] This embodiment adds a second rotating shaft 24 below the first rotating shaft 23 and connects it to a second support rod 22, forming a more stable support structure. This design not only enhances the vertical support force of the template body 1 but also improves its horizontal stability, ensuring that the template will not tilt or shift during construction. The introduction of the second rotating shaft 24 allows the second support rod 22 to also rotate around the shaft, increasing the flexibility of the first support component 2 and enabling it to adapt to support requirements at different heights and angles. When adjusting the template position or carrying out construction, operators can more easily adjust the angle and position of the support rod.

[0067] like Figure 1 As shown, the other end of the second support rod 22 has a ground anchor hole 221. The first support assembly 2 also includes an anchor 25, which can pass through the ground anchor hole 221 to fix the other end of the second support rod 22 to the ground 3.

[0068] In this embodiment, by fixing the other end of the second support rod 22 to the ground 3 with anchor nails 25, a more stable support structure is formed. This design significantly enhances the stability of the formwork body 1 and the structure above it, especially when subjected to large loads or external forces such as wind, effectively preventing the formwork from overturning or shifting. A stable support structure is an important guarantee for construction safety. Fixing the second support rod 22 to the ground 3 ensures that construction workers will not face safety risks due to the swaying or tilting of the formwork when working on it. At the same time, this also helps to reduce construction accidents caused by unstable support.

[0069] like Figure 1 As shown, a tie rod hole 12 is formed at the top of the template body 1, and the second support component 6 is a tie rod. The tie rod can pass through the tie rod hole 12 to fix the top of the template body 1 onto the solidified castable material 5. The castable material 5 includes concrete 51 and vertical reinforcement 52. The vertical reinforcement 52 is vertically set in the concrete 51, and one end of the vertical reinforcement 52 can extend downward through the concrete 51. The tie rod can pass through the tie rod hole 12 and be fixedly connected to one end of the vertical reinforcement 52 to fix the top of the template body 1 to the castable material 5.

[0070] In this embodiment, the connection strength between the formwork body 1 and the castable material 5 is significantly improved through the fixed connection of the tie rod and the vertical reinforcement 52, ensuring that the formwork will not shift or deform during the pouring process, thereby guaranteeing the shape and dimensional accuracy of the castable material 5. This embodiment uses the tie rod as the second support component 6, simplifying the formwork fixing process. Construction workers can quickly pass the tie rod through the tie rod hole 12 and fix it to the vertical reinforcement 52, thus saving a significant amount of installation time and labor costs. At the same time, this design also facilitates the disassembly and reuse of the formwork.

[0071] like Figure 1 As shown, a tie rod hole stiffening rib 13 is also formed on the top of the template body 1, and the tie rod hole stiffening rib 13 is located on the side of the tie rod hole 12.

[0072] In this embodiment, the addition of stiffening ribs 13 around the tie rod holes significantly enhances the structural strength of the template body 1 around the tie rod holes 12, helping to prevent local deformation or damage to the template when subjected to tie rod tension, thereby ensuring the overall stability and service life of the template. Simultaneously, the stiffening ribs 13 provide a more robust support surface for the tie rods, enabling a more secure connection between the tie rods and the template body 1, reducing the risk of loosening or detachment of the tie rods during stress, and improving the reliability of the connection between the template and the cast-in-place material 5.

[0073] like Figure 3 and Figure 4 As shown, it also includes a pouring guide plate 7, which is installed at an angle on the top of the template body 1; a groove 14 is formed on the top of the template body 1, and the groove 14 extends along the length direction of the template body 1; the groove 14 is adapted to the pouring guide plate 7, the pouring guide plate 7 is installed on the groove 14, and can move on the groove 14.

[0074] The pouring guide plate 7 guides the pouring material 5 to be poured in a predetermined direction and along a predetermined path, thus ensuring the orderliness and accuracy of the pouring process. This helps reduce problems such as grout leakage and air bubbles during pouring, improving the pouring quality. The design of the pouring guide plate 7 and the chute 14 allows construction workers to more easily adjust the pouring direction without frequently moving the formwork or repositioning the pouring point. This significantly saves construction time and labor costs, improving construction efficiency.

[0075] In this embodiment, the pouring guide plate 7 includes a third support rod 71 and a guide ramp 72. The guide ramp 72 is adapted to the chute 14 and is installed on the chute 14, and can move on the chute 14 to improve the construction efficiency during concrete 51 pouring. One end of the third support rod 71 is fixed to the guide ramp 72, and the other end is supported on the ground 3. The third support rod 71 provides additional support for the pouring guide plate 7, enhances its stability during the pouring process, and helps prevent the guide ramp 72 from displacing or deforming under the pressure of the pouring material.

[0076] like Figure 1 and Figure 2 As shown, a first stiffening rib 15 and a second stiffening rib 16 are also formed on the template body 1. The first stiffening rib 15 and the second stiffening rib 16 are intersecting and arranged, with the first stiffening rib 15 extending along the length direction of the template body 1 and the second stiffening rib 16 extending along the height direction of the template body 1.

[0077] The intersecting arrangement of the first stiffening rib 15 and the second stiffening rib 16 forms a stable support network, significantly enhancing the structural strength of the formwork body 1 in both length and height directions. The addition of the first stiffening rib 15 and the second stiffening rib 16 enables the formwork body 1 to withstand greater loads, including the weight of the cast-in-place material, the pressure of construction equipment, and external factors such as wind. This helps prevent the formwork from deforming or breaking due to excessive stress during the casting process, ensuring the accuracy and stability of the cast-in-place structure.

[0078] In this embodiment, as Figure 2 As shown, a rubber pad 17 is also provided on the template body 1. Two adjacent template bodies 1 on the same layer are connected by the rubber pad 17. The rubber pad 17 has excellent elasticity and sealing performance, and can fit tightly between two adjacent template bodies 1, effectively preventing the pouring material 5 from seeping out from the template gaps during the pouring process, thus ensuring the integrity and quality of the poured structure.

[0079] In this embodiment, as Figure 1 As shown, a cutting edge 18 is also formed on the template body 1. The cutting edge 18 is located at the bottom of the template body 1 and is used to insert the template body 1 more firmly into the ground 3, thereby enhancing the stability of the template during the pouring process, preventing the template from tilting or collapsing due to excessive force during the pouring process, and ensuring the accuracy and safety of the poured structure.
