Description

Technical Field

[0001] The invention relates to the technical field of reverse construction method, in particular to a reverse construction method side wall formwork. Background Art

[0002] In modern building construction, reverse construction is a method of excavating layer by layer from the ground downwards while carrying out structural construction at the same time. Its characteristics are that it can effectively utilize underground space and reduce the impact on the surrounding environment. During the reverse construction process, the installation and fixation of the side wall formwork is crucial. In the existing reverse construction, a triangular support structure is often set at the bottom of the formwork (such as patent CN112709217B), and the formwork is firmly fixed to the ground through a triangular frame welded from materials such as steel pipes or steel sections. This support method can still meet the stability requirements in the initial stage when the excavation depth is shallow and the load on the formwork is small.

[0003] However, as the excavation depth increases, the uncertainty of ground conditions, such as soft soil and high groundwater level, may cause the triangular support structure to sink or tilt, which in turn leads to insufficient overall stability of the formwork, prone to shaking or offset problems, affecting the accuracy and quality of concrete pouring, and may even pose a threat to the safety of the construction site. Summary of the invention

[0004] The purpose of the present invention is to provide a reverse construction side wall formwork to solve the problem that the existing side wall formwork only relies on the triangular support structure at the bottom for fixation, which may have insufficient stability.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A reverse construction side wall formwork comprises: a formwork body and a first support assembly, wherein the first support assembly is installed at the bottom of the formwork body and is used to support the formwork body obliquely on the ground; the formwork body can form a cavity with the rock wall, and the cavity is used to fill the casting material; a second support assembly, wherein the second support assembly is installed at the top of the formwork body and is used to be fixedly connected to the solidified casting material located on a layer above the formwork body, so that the top of the formwork body is fixed on the solidified casting material.

[0007] According to the above technical means, the present invention realizes all-round and stable support for the formwork body through two sets of upper and lower support components to solve the problem that the existing side wall formwork only relies on the triangular support structure at the bottom for fixation, which may have insufficient stability. The present invention not only sets a first support component at the bottom of the formwork body for inclined support to ensure that the formwork can stand firmly on the ground, but also adds a second support component on the top of the formwork body. In the process of pouring layer by layer in the reverse method, the formwork body of one layer under construction can be fixedly connected with the solidified pouring material of the upper layer through the second support component on the top, thereby realizing the firm fixation of the top of the formwork body.

[0008] Through the coordinated action of the upper and lower groups of supporting components, the reverse construction side wall formwork can maintain its original position and shape even if it encounters greater pressure or vibration during the pouring process, effectively avoiding problems such as formwork deformation or displacement. It not only improves construction efficiency, but also ensures that the pouring material can be evenly and accurately filled into the cavity, providing a strong guarantee for the subsequent project quality.

[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, and the other end is fixed to the ground.

[0010] According to the above technical means, the combined design of the first support rod and the second support rod in the present invention provides dual support for the formwork body. The first support rod is rotatably mounted on the formwork body at one end, and the other end is supported on the ground, so that the formwork body can maintain the required inclination angle. The second support rod is located below the first support rod, and is also rotatably mounted on the formwork body at one end, and the other end is fixed on the ground, further enhancing the stability and supporting force of the formwork body. This dual support structure can effectively disperse the pressure on the formwork body during the pouring process, prevent the formwork from being deformed or displaced due to uneven force, thereby ensuring uniform filling of the casting material and accuracy of the structure.

[0011] The first support rod and the second support rod are both rotatable, so that the first support assembly can be quickly and conveniently opened to the required angle during operation to meet the needs of template bodies with different inclination angles. At the same time, after the operation is completed, the first support rod and the second support rod can be folded up, so that the template body can become more compact and light when no support is needed, which is convenient for pushing and transporting operations, and convenient for the storage and management of the template.

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

[0013] According to the above technical means, through the design of the first rotating shaft, the first support rod can rotate around the rotating shaft, so that the position of the entire first support assembly on the template body can be flexibly adjusted, increasing the flexibility and adaptability of the template system, and can adapt to different working environments and installation requirements. When the first support assembly is not needed for support, the first support rod can be rotated to fold or move it to a position that does not occupy too much space, which helps to optimize space utilization, especially in scenes with limited space.

[0014] Furthermore, support stiffening ribs are formed on the template body, and the first rotating shaft is rotatably mounted on the support stiffening ribs.

[0015] According to the above technical means, the support stiffening ribs, as the reinforcement part of the formwork body, can significantly improve the bearing capacity and anti-deformation ability of the formwork. Installing the first rotating shaft on the support stiffening ribs can ensure that the formwork body can remain stable without shaking or deformation when the first support assembly is rotated and adjusted. By installing the first rotating shaft on the support stiffening ribs, the structural strength of the formwork body can be more effectively utilized, so that the first support assembly can provide more stable and reliable support. This helps to improve construction efficiency and reduce construction delays and safety issues caused by unstable support.

[0016] Furthermore, the first support assembly also includes a second rotating shaft, which is rotatably mounted on the template body and is 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 can be rotatably mounted on the template body.

[0017] According to the above technical means, a more stable support structure is formed by adding a second rotating shaft below the first rotating shaft and connecting the second support rod. This design not only enhances the supporting force of the template body in the vertical direction, but also improves its stability in the horizontal direction, ensuring that the template will not tilt or shift during the construction process. The introduction of the second rotating shaft allows the second support rod to also rotate around the rotating shaft, increasing the flexibility of the first support assembly so that it can adapt to support requirements of different heights and angles. When adjusting the template position or performing construction, the operator can more conveniently adjust the angle and position of the support rod.

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

[0019] According to the above technical means, a more stable support structure is formed by fixing the other end of the second support rod to the ground through anchor nails. This design significantly enhances the stability of the formwork body and the structure above it, especially when subjected to large loads or external forces such as wind, and can effectively prevent 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 can ensure that construction workers will not face safety risks due to shaking or tilting of the formwork when working on the formwork. At the same time, this also helps to reduce construction accidents caused by unstable support.

[0020] Furthermore, a tie rod hole is formed at the top of the formwork body, and the second supporting assembly is a tie rod, which can pass through the tie rod hole to fix the top of the formwork body on the solidified casting material; the casting material includes concrete and vertical bars, the vertical bars are vertically arranged in the concrete, and one end of the vertical bars can pass through the concrete and extend downward; the tie rod can pass through the tie rod hole and be fixedly connected to one end of the vertical bar to fix the top of the formwork body to the casting material.

[0021] According to the above technical means, the connection strength between the formwork body and the casting material is significantly improved by the fixed connection between the tie rod and the vertical reinforcement, ensuring that the formwork will not be displaced or deformed during the casting process, thereby ensuring the shape and dimensional accuracy of the casting material. The present invention uses the tie rod as the second support component to simplify the fixing process of the formwork. Construction personnel can quickly pass the tie rod through the tie rod hole and fix it with the vertical reinforcement, thereby saving a lot of installation time and labor costs. At the same time, 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] According to the above technical means, the addition of the tie rod hole stiffening ribs significantly enhances the structural strength of the formwork body around the tie rod hole, which helps prevent the formwork from being locally deformed or damaged when subjected to the tension of the tie rod, thereby ensuring the overall stability and service life of the formwork. At the same time, the tie rod hole stiffening ribs provide a more solid support surface for the tie rod, allowing the tie rod to be more firmly connected to the formwork body, reducing the risk of the tie rod loosening or falling off during the force process, and improving the reliability of the connection between the formwork and the casting material.

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

[0025] According to the above technical means, 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 to reduce problems such as leakage and bubbles during the pouring process and improve the pouring quality. The design of the pouring guide plate and the chute allows construction workers to adjust the pouring direction more conveniently without having to frequently move the template or reposition the pouring point. This greatly saves construction time and labor costs and improves 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 arranged to intersect, and the first stiffening rib extends along the length direction of the template body, and the second stiffening rib extends along the height direction of the template body.

[0027] According to the above technical means, the intersection of the first stiffening rib and the second stiffening rib forms a stable support network, which significantly enhances the structural strength of the formwork body in the length and height directions. The addition of the first stiffening rib and the second stiffening rib enables the formwork body to withstand greater loads, including the weight of the casting material, the pressure of the construction equipment, and external factors such as wind force. It helps to prevent the formwork from being deformed or damaged due to excessive force during the casting process, and ensures the accuracy and stability of the casting structure.

[0028] Beneficial effects achieved by the present invention:

[0029] 1. The present invention realizes all-round and stable support for the formwork body through two sets of upper and lower support components, so as to solve the problem that the existing side wall formwork only relies on the triangular support structure at the bottom for fixation, which may have insufficient stability. The present invention not only sets a first support component at the bottom of the formwork body for inclined support to ensure that the formwork can stand firmly on the ground, but also adds a second support component on the top of the formwork body. In the process of pouring layer by layer in the reverse method, the formwork body of one layer under construction can be fixedly connected with the solidified pouring material of the upper layer through the second support component on the top, thereby realizing the firm fixation of the top of the formwork body.

[0030] 2. Through the synergistic effect of the upper and lower groups of support components, the reverse construction side wall formwork can maintain its original position and shape even if it encounters greater pressure or vibration during the pouring process, effectively avoiding problems such as formwork deformation or displacement, which not only improves the construction efficiency, but also ensures that the pouring material can be evenly and accurately filled into the cavity, providing a strong guarantee for the subsequent engineering quality.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0050] The technical solution of this embodiment is described in detail below in conjunction with specific drawings.

[0051] like Figure 1As shown, this embodiment proposes a reverse construction side wall formwork, including: a formwork body 1 and a first support assembly 2, the first support assembly 2 is installed at the bottom of the formwork body 1, and the first support assembly 2 is used to support the formwork body 1 obliquely 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 casting material 5; the second support assembly 6, the second support assembly 6 is installed on the top of the formwork body 1, and the second support assembly 6 is used to be fixedly connected with the solidified casting 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 casting material 5.

[0052] In the specific reverse construction process, the first ground layer is constructed first: after the shaft is excavated to the designed elevation, the first support assembly 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 the formwork body 1 and the rock wall 8. The casting material 5 is filled in the cavity 4, and the casting speed and amount are controlled to ensure that the casting material 5 can evenly fill the entire cavity 4. After the casting material 5 is completely solidified, the formwork is removed to prepare for the next layer of construction.

[0053] like Figure 3 and Figure 4 As shown, construction is then carried out layer by layer (the second layer and above): after the previous layer of casting material 5 is completely solidified, an excavator or other excavation equipment is used to dig downward to the designed elevation to form a new construction space. The first support assembly 2 is installed at the bottom of the formwork body 1 and adjusted to a suitable inclination angle to ensure that the angle of the formwork body 1 is consistent with that of the previous layer of casting material 5. The second support assembly 6 is then installed on the top of the formwork body 1 and fixedly connected to the solidified casting material 5. The casting material 5 is filled into the new cavity 4 and the above casting process is repeated.

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

[0055] This embodiment realizes all-round and stable support for the formwork body 1 through two sets of upper and lower support components, so as to solve the problem that the existing side wall formwork only relies on the triangular support structure at the bottom for fixation, which may have insufficient stability. This embodiment not only sets a first support component 2 at the bottom of the formwork body 1 for inclined support to ensure that the formwork can stand firmly on the ground 3, but also adds a second support component 6 at the top of the formwork body 1. In the process of pouring layer by layer in the reverse method, the formwork body 1 under construction can be fixedly connected with the solidified pouring material 5 of the upper layer through the second support component 6 at the top, thereby realizing the firm fixation of the top of the formwork body 1.

[0056] Through the coordinated action of the upper and lower groups of supporting components, the reverse construction side wall formwork can maintain its original position and shape even if it encounters greater pressure or vibration during the pouring process, effectively avoiding problems such as formwork deformation or displacement. It not only improves construction efficiency, but also ensures that the pouring material can be evenly and accurately filled into the cavity, providing a strong guarantee for the subsequent project quality.

[0057] like Figure 3 and Figure 4 As shown, in this embodiment, a reverse construction side wall formwork also includes a closing net 9, which is connected to the bottom of the formwork body 1 and laid under the casting material 5 during the casting process, and is used to isolate the contact between the ground 3 soil layer and the casting material 5, thereby reducing the pollution of the working surface. When the upper layer of casting material 5 solidifies, the closing net 9 of this layer is removed to increase the roughness of the junction of the two layers, making the structure more integrated and effectively preventing water leakage. Preferably, in this embodiment, the closing net 9 is made of galvanized material, which has good corrosion resistance and rust resistance, and can maintain the integrity and functionality of the closing net for a long time, further enhancing its protective effect on the casting 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 to keep the template body 1 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 double support for the template body 1. The first support rod 21 is rotatably mounted on the template body 1 at one end, and the other end is supported on the ground, so that the template body 1 can maintain the required inclination angle. The second support rod 22 is located below the first support rod 21, and is also rotatably mounted on the template body 1 at one end, and the other end is fixed on the ground, further enhancing the stability and supporting force of the template body 1. This double support structure can effectively disperse the pressure on the template body 1 during the pouring process, prevent the template from being deformed or displaced due to uneven force, thereby ensuring the uniform filling of the casting material 5 and the accuracy of the structure.

[0060] The first support rod 21 and the second support rod 22 are both rotatable, so that the first support assembly 2 can be quickly and conveniently opened to the required angle during operation to meet the needs of the template body 1 with different inclination angles. At the same time, after the operation is completed, the first support rod 21 and the second support rod 22 can be retracted, so that the template body 1 can become more compact and lightweight when no support is needed, which is convenient for pushing and transporting operations, and facilitates the storage and management of the template.

[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, and 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] Through the design of the first rotating shaft 23, the first support rod 21 can rotate around the rotating shaft, so that the position of the entire first support assembly 2 on the template body 1 can be flexibly adjusted, increasing the flexibility and adaptability of the template system, and can adapt to different working environments and installation requirements. When the first support assembly 2 is not needed for support, the first support rod 21 can be rotated to fold or move it to a position that does not occupy too much space, which helps to optimize space utilization, especially in scenes with limited space.

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

[0064] The support stiffening rib 11, as a reinforcement part of the formwork body 1, can significantly improve the bearing capacity and anti-deformation ability of the formwork. Installing the first rotating shaft 23 on the support stiffening rib 11 can ensure that the formwork body 1 can remain stable without shaking or deformation when the first support assembly 2 is rotated and adjusted. By installing the first rotating shaft 23 on the support stiffening rib 11, the structural strength of the formwork body 1 can be more effectively utilized, so that the first support assembly 2 can provide more stable and reliable support. This helps to improve construction efficiency and reduce 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 the second rotating shaft 24 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 can be rotatably mounted on the template body 1.

[0066] This embodiment forms a more stable support structure by adding a second rotating shaft 24 below the first rotating shaft 23 and connecting the second support rod 22. This design not only enhances the support force of the template body 1 in the vertical direction, but also improves its stability in the horizontal direction, ensuring that the template will not tilt or shift during the construction process. The introduction of the second rotating shaft 24 allows the second support rod 22 to also rotate around the rotating shaft, increasing the flexibility of the first support assembly 2, so that it can adapt to support requirements of different heights and angles. When adjusting the template position or performing construction, the operator can more conveniently adjust the angle and position of the support rod.

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

[0068] This embodiment forms a more stable support structure by fixing the other end of the second support rod 22 to the ground 3 through the anchor 25. This design significantly enhances the stability of the formwork body 1 and the structure above it, and can effectively prevent the formwork from overturning or deflecting, especially when subjected to large loads or external forces such as wind. A stable support structure is an important guarantee for construction safety. Fixing the second support rod 22 to the ground 3 can ensure that construction workers will not face safety risks due to shaking or tilting of the formwork when working on the formwork. 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 formwork body 1, and the second supporting assembly 6 is a tie rod, which can pass through the tie rod hole 12 to fix the top of the formwork body 1 on the solidified casting material 5; the casting material 5 includes concrete 51 and vertical ribs 52, the vertical ribs 52 are vertically arranged in the concrete 51, and one end of the vertical ribs 52 can pass through the concrete 51 and extend downward; the tie rod can pass through the tie rod hole 12 and be fixedly connected to one end of the vertical rib 52, so as to fix the top of the formwork body 1 to the casting material 5.

[0070] In this embodiment, the connection strength between the formwork body 1 and the casting material 5 is significantly improved by the fixed connection between the tie rod and the vertical rib 52, ensuring that the formwork will not be displaced or deformed during the casting process, thereby ensuring the shape and dimensional accuracy of the casting material 5. In this embodiment, the tie rod is used as the second support component 6, which simplifies the fixing process of the formwork. The construction personnel can quickly pass the tie rod through the tie rod hole 12 and fix it to the vertical rib 52, thereby saving a lot 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] The addition of the tie rod hole stiffening rib 13 in this embodiment significantly enhances the structural strength of the template body 1 around the tie rod hole 12, which helps prevent the template from being partially deformed or damaged when subjected to the tension of the tie rod, thereby ensuring the overall stability and service life of the template. At the same time, the tie rod hole stiffening rib 13 provides a more solid support surface for the tie rod, so that the tie rod can be more firmly connected to the template body 1, reducing the risk of the tie rod loosening or falling off during the force process, and improving the connection reliability between the template and the casting material 5.

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

[0074] The pouring guide plate 7 can guide the pouring material 5 to be poured in a predetermined direction and path, thereby ensuring the orderliness and accuracy of the pouring process. This helps to reduce problems such as leakage and bubbles during the pouring process and improve the pouring quality. The design of the pouring guide plate 7 and the chute 14 allows construction workers to adjust the pouring direction more conveniently without having to frequently move the template or reposition the pouring point. This greatly saves construction time and labor costs and improves construction efficiency.

[0075] In this embodiment, the pouring guide plate 7 includes a third support rod 71 and a guide inclined plate 72. The guide inclined plate 72 is adapted to the slide 14. The guide inclined plate 72 is installed on the slide 14 and can move on the slide 14 to improve the construction efficiency when pouring concrete 51. One end of the third support rod 71 is fixed on the guide inclined plate 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 inclined plate 72 from being displaced or deformed under the pressure of the pouring material.

[0076] like Figure 1 and Figure 2 As shown, the template body 1 is further formed with a first stiffening rib 15 and a second stiffening rib 16 , which are arranged to intersect with each other, and the first stiffening rib 15 extends along the length direction of the template body 1 , and the second stiffening rib 16 extends along the height direction of the template body 1 .

[0077] The intersection of the first stiffening rib 15 and the second stiffening rib 16 forms a stable support network, which significantly enhances the structural strength of the formwork body 1 in the 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 casting material, the pressure of the construction equipment, and external factors such as wind force. This helps prevent the formwork from being deformed or damaged due to excessive force during the casting process, and ensures the accuracy and stability of the casting structure.

[0078] In this embodiment, Figure 2 As shown, a rubber pad 17 is also provided on the template body 1, and 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 casting material 5 from seeping out from the template gap during the casting process, thereby ensuring the integrity and quality of the casting structure.

[0079] In this embodiment, Figure 1 As shown, a blade foot 18 is also formed on the template body 1. The blade foot 18 is located at the bottom end 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 pouring structure.
