Description

Technical Field

[0001] This invention relates to the field of facade thin-layer repair technology, and in particular to a double-sided quick-release suspended grouting template for facade thin-layer repair. Background Technology

[0002] Ship locks, as an important component of waterway engineering, are hydraulic structures built to overcome water level differences, allowing ships or fleets to rise and fall. Due to the poor strength, hardness, and density of cement-based materials, their abrasion resistance and weathering resistance are also poor. Furthermore, during long-term service, the number of steel transport vessels, including those exceeding tonnage, has continuously increased, and vessels frequently dock haphazardly, causing damage to the upstream and downstream lock chamber walls. Simultaneously, affected by factors such as moisture erosion, water flow scouring, and water pollution, many locks that have been in operation for years exhibit damage such as concrete peeling and exposed rebar on the lock chamber walls, and the affected areas are continuously expanding. This is a problem that urgently needs to be addressed.

[0003] The lock area is large, and manual repairs are time-consuming, inconvenient, and expensive, necessitating the use of grouting with formwork. However, conventional grouting techniques are prone to problems such as formwork bulging, misalignment, and even bursting after formwork installation, affecting the appearance quality and leading to significant construction losses and high costs. Furthermore, the lock's water level restricts the installation of formwork support frames and other structures, resulting in difficulties in formwork installation and reinforcement, low formwork turnover efficiency, and poor overall performance. Therefore, commonly used grouting formwork cannot meet the repair needs of this special working condition. Summary of the Invention

[0004] To address the aforementioned issues, this invention discloses a double-sided quick-release suspended grouting formwork for thin-layer repair of facades. This overcomes the limitation that a single formwork piece can only provide one repair thickness and eliminates the technical defects of existing suspended formwork where the support frame function restricts high-altitude operations. It can improve formwork splicing efficiency and turnover speed. Due to its lightweight structure and ease of operation, it can reduce reliance on heavy machinery and equipment, thereby reducing equipment rental and operating costs.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: This invention provides a double-sided quick-release suspended grouting template for thin-layer repair of facades. The suspended grouting template includes a main template, an auxiliary template, a template assembly and splicing component, and a fastening component. The auxiliary template is installed and fixed to the main template via an arc-shaped tenon joint groove. The template assembly and splicing component is fitted onto the template assembly and splicing groove of the main template. The fastening component is used to install and fix the template on the surface to be repaired.

[0006] Furthermore, the main template has an arc-shaped tenon joint groove on its side and a horizontal reinforcing rib, a vertical reinforcing rib, grouting holes, an upper splicing protrusion, and a lower splicing groove on its back. The arc-shaped tenon joint groove is a template assembly splicing groove, the vertical reinforcing rib has fastener holes, and the grouting holes include an upper grouting hole and a lower grouting hole. The template assembly splicing groove is a trapezoidal tenon and mortise structure, used to install the horizontal splicing components and auxiliary template splicing components of the template assembly. The upper splicing protrusion is located on the first horizontal reinforcing rib and is used to splice the main template or install the top cover auxiliary template. The lower splicing groove is located on the sixth horizontal reinforcing rib and is used to splice the main template or install the bottom support auxiliary template. The upper splicing protrusion and the lower splicing groove, when spliced ​​together, can be used to install the vertical splicing components of the template assembly.

[0007] Furthermore, the auxiliary templates include a bottom left auxiliary template, a bottom right auxiliary template, a heightened left auxiliary template, a heightened right auxiliary template, a top left auxiliary template, a top right auxiliary template, a bottom support auxiliary template, and a top cover auxiliary template. The bottom left, bottom right, top left, and top right auxiliary templates each include an arc-shaped tenon joint groove, fastener holes, a semi-circular tenon joint groove, and a slot for longitudinal splicing components for template assembly. The heightened left and right auxiliary templates each include an arc-shaped tenon joint groove, fastener holes, and a slot for longitudinal splicing components for template assembly. The splicing component slots include fastener holes, a semi-circular tenon joint groove, and a convex joint groove; the top cover auxiliary template includes fastener holes, a semi-circular tenon joint groove, and a concave joint groove; the top cover auxiliary template also has two rows of venting grooves. The bottom left auxiliary template, bottom right auxiliary template, raised left auxiliary template, raised right auxiliary template, top left auxiliary template, top right auxiliary template, bottom support auxiliary template, and top cover auxiliary template are double-sided. Using the auxiliary templates on both sides (a) or both sides (b) can achieve two repair thicknesses.

[0008] Furthermore, the template assembly splicing component includes a template assembly horizontal splicing component, a template assembly auxiliary template splicing component, and a template assembly vertical splicing component. The template assembly horizontal splicing component is provided with a template assembly horizontal splicing component slot and a template assembly horizontal splicing component tail wing. The template assembly auxiliary template splicing component is provided with a template assembly auxiliary template splicing component slot, a template assembly vertical splicing component insert, and fastener holes. The template assembly vertical splicing component is provided with a template assembly vertical splicing component slot and fastener holes. The template assembly horizontal splicing component is vertically fitted onto the template assembly splicing groove of two horizontally overlapping main templates. The template assembly auxiliary template splicing component is horizontally fitted onto the template assembly splicing groove of two vertically overlapping main templates. The template assembly vertical splicing component insert is inserted into the template assembly vertical splicing component slot of the auxiliary template and fixed to the fastener holes of the auxiliary template by fastening components. The template assembly vertical splicing component is installed on the first horizontal reinforcing rib and the sixth horizontal reinforcing rib of the two vertically overlapping main templates and fixed to the fastener holes of the vertical reinforcing ribs by fasteners.

[0009] The beneficial effects of this invention are as follows: 1. The double-sided quick-release suspended grouting template for thin-layer repair of facades provided by this invention can be quickly and continuously assembled, and the grouting area can be freely adjusted: the arc-shaped tongue and tenon joint groove, the upper splicing protrusion and the lower splicing groove of the main template and the horizontal splicing component of the template assembly realize the quick and free overlap and disassembly of adjacent templates. The template combination form can be flexibly adjusted according to the actual repair needs, thereby changing the repair area range, which is suitable for repair work on irregular damaged surfaces; the template can be quickly installed, fixed and disassembled on the facade through the splicing and fastening components of the main template and auxiliary template, which speeds up the assembly speed.

[0010] 2. The double-sided quick-release suspended grouting template for thin-layer repair of facades provided by this invention can reduce the risk of grout leakage from the template: the main template and auxiliary template, as well as the auxiliary templates, are assembled through mortise and tenon structures, making the connection between the various components of the template tighter. The overlapping of the mortise and tenon structures changes the path of the grout leakage channel, thereby significantly reducing the risk of cement grout leakage during the grouting process; at the same time, the mortise and tenon structure has self-locking characteristics, enhancing the overall stability of the template, making it less prone to deformation and detachment under grouting pressure, further ensuring the sealing effect.

[0011] 3. The double-sided quick-release suspended grouting template for thin-layer repair of facades provided by this invention can optimize the template structure, realize double-sided use, reduce template weight, and facilitate transportation: The double-layer reinforcing rib system (horizontal and vertical reinforcing ribs are arranged in a cross pattern) set on the back of the main template significantly improves the template's resistance to deformation; the auxiliary template is double-sided, and the auxiliary template can be used on both sides (a) or both sides (b) to achieve two repair thicknesses. Through the combination of the upper, lower, left, and bottom right auxiliary templates, combined with the venting groove design, the problem of air bubble residue during the grouting process is effectively solved, increasing the constraint stress while reducing the gas pressure inside the template, enhancing the template stability and ensuring the density of the repair layer.

[0012] 4. The double-sided quick-release suspended grouting formwork for thin-layer facade repair provided by this invention can optimize the construction process: the suspended installation method eliminates the disadvantages of traditional formwork being restricted by ground support frames, making it particularly suitable for facade repair scenarios such as ship locks. The installation height can be flexibly adjusted according to water level changes, reducing the risk of high-altitude operations and saving equipment rental and labor costs. The formwork assembly design eliminates the disadvantages of traditional grouting formwork segmented construction, where the middle formwork positioning anchor bolts need to be reserved while the left and right side formworks are installed, resulting in the need to fill the reserved anchor bolt holes separately. The repair surface is integrally formed, without cold joints, construction joints, or other weak parts. Adjacent formworks can be freely disassembled and assembled after curing, resulting in high formwork turnover efficiency. Attached Figure Description

One embodiment of the suspended grouting template is as follows: The grouting pipe of the commercially available grouting machine overlaps the lower grouting hole 105b of the lower main formwork 100. Pressure grouting delivers the grout to the grouting cavity formed by the main formwork 100 and the surface to be repaired. When the grout level exceeds the upper grouting hole 105a, the grouting pipe is installed in the upper grouting hole 105a. When the grout level exceeds the lower grouting hole 105b of the upper main formwork 100, the grouting pipe is installed in the lower grouting hole 105b of the upper main formwork 100. When the grout level again exceeds the upper grouting hole 105a of the upper main formwork 100, the grouting pipe is installed in the upper grouting hole 105a of the upper main formwork 100, ultimately achieving grouting of multiple formworks. The top cover auxiliary formwork 208 has a pre-reserved venting groove 213, effectively solving the problem of residual air bubbles during the grouting process. This increases the constraint stress while reducing the gas pressure inside the formwork, enhancing the stability of the formwork and ensuring the density of the repair layer.
