Description

Technical Field

[0001] This invention relates to the field of construction formwork technology, and in particular to an assembly formwork for a mooring post niche on a pier and its construction support and dismantling method. Background Technology

[0002] In the construction of mooring post niches for ship piers, traditional monolithic box-type formwork structures typically consist of 8 formwork panels (such as...). Figure 12 As shown, the formwork includes four corner molds and four side plates. All components are bolted together to form a whole. Supporting screws are installed inside the cavity to enhance the overall rigidity and strength of the formwork, thus resisting the lateral pressure generated during concrete pouring. During construction, this integral box-shaped formwork needs to be bolted to the side molds of the mooring pier. Simultaneously, it connects to the pre-embedded steel plates of the mooring bollards using pre-drilled holes at the bottom to ensure that the installation dimensions meet design standards.

[0003] However, existing technologies have significant limitations. In the demolding process, after the concrete pouring is completed, the connecting bolts between the side formwork of the mooring bollard and the box formwork must be removed first to demold the side formwork. Then, construction workers need to enter the mooring bollard box to remove the threaded rods and formwork connecting bolts one by one. The formwork is then disassembled into sections and manually carried out of the niches in batches. Finally, the box is removed along the cover plate to complete the batch and section dismantling of the overall assembled formwork. This demolding method is not only cumbersome but also inefficient, greatly increasing the labor intensity and safety risks for construction workers.

[0004] Furthermore, the presence of internal support screws in the existing formwork prevents the bollards from being pre-installed inside the formwork before the niche construction. In actual construction, after the niche is formed, manual labor combined with lifting equipment is required to hoist the bollards a second time and push them into the niche for secure installation. This process involves multiple positioning and adjustments, which not only prolongs the construction period but also increases the risk of installation accuracy deviations due to repeated handling, making it difficult to meet the high-efficiency and precise construction requirements of modern engineering. Summary of the Invention

[0005] The purpose of this invention is to provide a template for assembling the mooring post niche of a pier and a method for its construction and dismantling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A type of assembly template for mooring post niches on ship piers includes a pair of side bottom corner templates. Several auxiliary demolding components are evenly spaced on the inner bottom surface of the side bottom corner templates. The tops of the two side bottom corner templates are connected to side top corner templates by several bolt groups. Auxiliary demolding components are provided on the inner walls of the back plates of both the side top corner templates and the side bottom corner templates. The two side top corner templates are connected to the top template by several bolt groups. The two side bottom corner templates and the top template are fixed to a back template by several bolt groups. The back template is composed of several pieces of wood. The two side bottom corner templates and the top template are also fixed to each other by a pair of diagonal braces.

[0007] As a preferred embodiment of the present invention, a plurality of first reinforcing ribs are provided on the inner wall of the side top corner template body, a pair of first splicing slots are provided on the connecting surface of the side top corner template body and the top template body, a pair of first connecting blocks are provided on the connecting surface of the bottom of the side top corner template body and the side bottom corner template body, and a first through groove is provided on the back side of the side top corner template body.

[0008] As a preferred embodiment of the present invention, the side bottom corner template body is provided with several second reinforcing ribs, and the top of the side bottom corner template body is provided with a second splicing slot corresponding to the position of the first connecting block. Several first connecting blocks are respectively inserted into several corresponding second splicing slots. The back of the side bottom corner template body is provided with a second through groove, and a first sealing strip is provided on the edge of the contact surface between the side bottom corner template body, the side top corner template body, and the back template body.

[0009] As a preferred embodiment of the present invention, a second connecting block is provided on both sides of the top template body at the position corresponding to the first splicing slot, and several second connecting blocks are respectively inserted into the corresponding first splicing slot. Several third reinforcing ribs are provided on the bottom surface of the top template body, and a second sealing strip is provided on the edge of the contact surface between the top template body and the side top corner template body and the back template body.

[0010] As a preferred embodiment of the present invention, the auxiliary demolding component includes a mounting frame, on which a hydraulic telescopic cylinder is provided. A baffle is provided at the top end of the telescopic rod of the hydraulic telescopic cylinder, and several baffles are respectively arranged in several first through slots and several second through slots.

[0011] As a preferred embodiment of the present invention, the auxiliary demolding assembly includes a mounting shell disposed on the bottom surface of the side corner template body, and several rotating shafts are movably disposed inside the mounting shell via several pairs of bearing seats, each of the rotating shafts being provided with a movable wheel.

[0012] As a preferred embodiment of the present invention, the front sides of the top corner template body and the bottom corner template body are respectively provided with a first hook and a second hook.

[0013] In a preferred embodiment of the present invention, both ends of the diagonal brace are respectively mounted on the second reinforcing rib and the third reinforcing rib by bolt groups.

[0014] As a preferred embodiment of the present invention, a method for assembling and disassembling the formwork for the mooring post niche of a ship pier includes two steps: formwork erection and demolding. Before setting up the formwork, the construction workers need to first pour concrete to the height required for the mooring bollards. At this point, the top surface of the mooring bollards serves as the foundation platform for the subsequent formwork installation. After the foundation pouring is completed, the top surface of the mooring bollards is precisely measured and laid out using surveying instruments such as a total station to determine the installation positions of the mooring bollards and formwork, providing a precise positioning basis for subsequent installation. Next, the bollard is first placed on top of the berthing pier using lifting equipment. During the lifting process, the lifting points are reasonably selected according to the weight and center of gravity of the bollard to prevent it from swaying or tilting. After being lifted to the designated position, the bollard is firmly fixed to the berthing pier by pre-embedded bolts or welding to ensure its accurate and stable position, providing a reliable benchmark for subsequent formwork installation. Next, using lifting equipment, the two side corner formwork panels are placed on top of the mooring pier, positioned on either side of the bollard. Before hoisting, the surface of the side corner formwork panels needs to be cleaned and inspected to ensure that the surface is flat, undamaged, and that the release agent is evenly applied. During placement, preliminary positioning is performed according to the pre-measured and laid-out positioning lines and the positioning marks on the formwork. Then, measuring tools such as levels and theodolites are used to precisely adjust the verticality, horizontality, and position of the formwork to ensure accurate positioning. After the position is determined, the two side corner formwork panels are fixed to the mooring pier using bolts. During bolt tightening, a diagonal tightening method is used to ensure even stress on the formwork and prevent deformation. Subsequently, the first splicing slots of the two side corner templates are aligned with the second splicing blocks on both sides of the top template and inserted. Bolts are then used to secure the two side corner templates to the top template. During bolt installation, the bolts are tightened according to the specified torque requirements to ensure a secure connection. After installation, the template is lifted using hoisting equipment, and the first mating blocks at the bottom of the two side corner templates are aligned with several second splicing slots on the side bottom corner template for positioning. After positioning, construction workers enter the template and use bolts to securely connect the side corner templates to the side bottom corner templates. During bolt connection, the tightening sequence and torque requirements are also followed to ensure a tight connection between all parts of the template. Subsequently, bolt sets are used to further support and fix the side bottom corner formwork and top formwork on both sides, respectively, by using several diagonal bracing rods. The arrangement of the diagonal bracing rods is reasonably designed according to factors such as the size and shape of the formwork and the lateral pressure during concrete pouring, forming a stable support system. The connection between the diagonal bracing rods and the formwork and the pier is firm and reliable, ensuring that the formwork can withstand large lateral pressure without deformation or displacement during concrete pouring. Finally, simply use bolt sets to fix the back plate between the top template body and the two side bottom corner template bodies. Before installing the back plate and after fixing the back plate, conduct a comprehensive inspection of the entire template system, including whether the template connection is firm, whether the support is stable, and whether the dimensions meet the design requirements. After the overall template installation is completed, the construction personnel need to install the template for the remaining part of the berthing pier on the top of the berthing pier and carry out the final pouring operation of the main body of the berthing pier. After the pier is fully cast and other formwork is removed, and the concrete reaches a certain strength, the formwork removal operation begins. First, workers enter the formwork to remove several bolt groups securing the back formwork. During removal, the bolts are loosened gradually in a specific order to prevent damage to the back plate due to uneven stress. Then, the wooden strips of the back formwork are removed one by one from inside the formwork. After all the wooden strips are removed, the structure is cleaned and inspected for future use. The hydraulic supply system pipelines were then connected to the interfaces of several hydraulic telescopic cylinders. After the construction workers exited, the cylinders were secured to several first and second hooks using traction and lifting equipment. Several hydraulic telescopic cylinders are simultaneously activated using a hydraulic supply system. These cylinders extend telescopic rods, which in turn push baffles against the inner wall of the niche. During this process, the hydraulic system controls the thrust and extension speed of the cylinders to ensure uniform stress on the formwork, allowing it to smoothly detach from the niche. Simultaneously, a traction device activates the pull ropes, applying both pushing and pulling forces outwards to the entire formwork. Through the combined action of hydraulic thrust and mechanical pull, the bond between the concrete and the formwork is overcome, ultimately pulling the entire formwork out of the poured niche. Finally, the entire construction work can be completed simply by lifting the formwork back using hoisting equipment. After the formwork is lifted back, it should be thoroughly cleaned, repaired, and maintained. All parts of the formwork should be checked for integrity, and any damaged parts should be replaced or repaired to prepare for the next use.

[0015] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: 1. This invention optimizes the number of templates to 5 pieces. By reducing the number of template splicing nodes, the time for setting up and dismantling the formwork is greatly shortened. Fewer templates mean fewer bolt connections and disassembly work, reducing the complexity of manual operation and enabling construction workers to complete the installation and dismantling of the templates more quickly, thus significantly improving construction efficiency.

[0016] 2. From the perspective of construction cost, this invention reduces the need for secondary installation of mooring bollards and repeated disassembly and transportation of formwork, thereby reducing labor and machinery usage costs. The stable formwork structure and good construction quality reduce later repair and maintenance costs. In terms of construction cycle, the efficient support and disassembly and overall demolding technology significantly shortens the construction period, enabling the project to be put into use more quickly and creating greater economic benefits.

[0017] This invention achieves one-time demolding by setting up auxiliary demolding components and auxiliary unloading components, and adopting a composite demolding technology of hydraulic jacking and mechanical traction. The hydraulic telescopic cylinder pushes the baffle to squeeze the inner wall of the niche, while the traction equipment applies an outward pulling force, which can quickly pull the entire template out of the niche. The moving wheels of the auxiliary unloading component facilitate the transfer of the template after disassembly, eliminating the need for manual handling of each piece, significantly improving demolding efficiency, greatly accelerating the construction progress, greatly reducing the physical exertion of construction workers, and effectively ensuring the personal safety of construction workers.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0021] like Figure 1-12 As shown, the present invention proposes an assembly template for a mooring column niche and its construction and dismantling method, which includes a pair of side bottom corner template bodies 2, forming the lower two sides of the template structure. An auxiliary demolding component 6 is provided on the inner bottom surface of the template to assist in the subsequent template dismantling work. The top of the side bottom corner template body 2 is connected to the side top corner template body 1 by bolt group, which is stable and easy to dismantle. An auxiliary demolding component 5 is installed on the inner back wall of both the side top corner template body 1 and the side bottom corner template body 2 to provide assistance for template demolding. The inner wall of the side top corner template 1 is provided with a first reinforcing rib 10 to enhance the template strength and prevent deformation during pouring. The connecting surface that contacts the top template 3 has a first splicing groove 11, which cooperates with the second connecting block 30 of the top template 3. The bottom connecting surface that contacts the side bottom corner template 2 has a first connecting block 12, which corresponds to the second splicing groove 21 of the side bottom corner template 2. With this structure and the addition of bolts for fixing, the connection is ensured to be accurate and firm. The back of the side top corner template 1 has a first through groove 14 to facilitate the extension of the telescopic rod of the demolding component 5. A second reinforcing rib 20 is provided inside the side bottom corner template body 2 to further improve the stability of the template. The second splicing groove 21 at the top fits with the first connecting block 12 of the side top corner template body 1. The second through groove 23 on the back corresponds to the first through groove 14 of the side top corner template body 1, which facilitates the installation of the auxiliary demolding component 5. A first sealing strip 24 is provided at the edge that contacts the side top corner template body 1 and the back template body 4 to ensure the sealing of the template splice and prevent grout leakage during concrete pouring. The second connecting blocks 30 on both sides of the top template body 3 are inserted into the first splicing groove of the side top corner template body 1. The bottom is provided with a third reinforcing rib plate 31, which together with the reinforcing rib plates of the side bottom corner template body 2 and the side top corner template body 1 to form a stable frame. The edge of the contact surface between the top template body 3 and the side top corner template body 1 and the back template body 4 is provided with a second sealing strip 32, which cooperates with the first sealing strip 24 to provide double protection for the sealing effect. The auxiliary demolding component 5 includes a mounting frame 50 on which a hydraulic telescopic cylinder 51 is mounted. The top of the telescopic rod of the hydraulic telescopic cylinder 51 is connected to a baffle 52. The baffle 52 is located in the first through groove 14 and the second through groove 23. During demolding, the hydraulic telescopic cylinder 51 pushes the baffle 52 against the inner wall of the niche, and the template is detached in conjunction with external traction. The mounting shell 60 of the auxiliary demolding component 6 is fixed to the inner bottom surface of the side bottom corner template body 2. A rotating shaft 62 is installed in the shell through a bearing seat 61. The rotating shaft 62 is equipped with a moving wheel 63. Several moving wheels 63 and the bottom surface of the side bottom corner template body 2 simultaneously contact the inner bottom surface of the niche. The moving wheels 63 play an auxiliary role, reduce the bottom friction, and make it easier to move the template after disassembly. During construction, the template as a whole remains stable according to gravity and is not affected by the moving wheels. The top corner template 1 and the bottom corner template 2 are respectively provided with a first hook 13 and a second hook 22 on the front, which are used to connect the lifting equipment and the traction equipment to meet the force requirements during the template lifting and demolding process. The two ends of the diagonal brace 7 are fixed to the second reinforcing rib plate 20 of the bottom corner template 2 and the third reinforcing rib plate 31 of the top template 3 by bolt groups, forming a triangular stable structure, which effectively resists the lateral pressure generated by concrete pouring and ensures the stability of the template during the construction process. The back formwork body 4 is composed of several vertical wooden strips 4 arranged horizontally and assembled by detachable bolt groups. During the subsequent demolding process, several wooden strips can be removed one by one.

[0022] During construction, before setting up the formwork, the workers first need to pour the concrete to the required height for the niches on the berth. Then, using lifting equipment, the mooring bollard 8 is placed on top of the berth. Next, the two side bottom corner formwork bodies 2 are placed on top of the berth, positioned on either side of the mooring bollard 8, and positioned according to the actual specifications of the formwork and the location of the niches. After the positions are determined, the two side bottom corner formwork bodies 2 are fixed to the berth using bolts. Then, the first splicing slots 11 of the two side top corner formwork bodies 1 are aligned with the second splicing blocks on both sides of the top formwork body 3 and inserted. The two side top corner formwork bodies 1 and the top formwork body 3 are then fixed together using bolts. The installation is then complete. Afterwards, the formwork is lifted using a hoisting device, and the first connecting blocks 12 at the bottom of the two side top corner template bodies 1 are aligned with several second splicing slots 21 and inserted for positioning. After positioning, the construction workers enter the formwork and use bolt sets to fix the side top corner template body 1 and the side bottom corner template body 2. Then, the bolt sets are used to further support and fix the side bottom corner template bodies 2 and the top template body 3 on both sides with several diagonal bracing rods 7 respectively. Finally, the back plate is fixed between the top template body 3 and the two side bottom corner template bodies 2 with bolt sets. The overall template installation is now complete. Finally, the construction workers need to install the template for the remaining part of the berthing pier on the top of the berthing pier and carry out the final pouring operation of the main body of the berthing pier. After the overall casting of the pier is completed and the formwork is removed, the formwork removal operation of this device is carried out. First, the construction personnel enter the formwork to remove several bolt groups that fix the back formwork body 4. Then, several wooden strips 40 of the back formwork body 4 are removed one by one and taken out from the formwork. The pipeline of the hydraulic supply system is connected to the interface of several hydraulic telescopic cylinders 51. After the construction personnel come out, the traction equipment and lifting equipment are fixed to several first hooks 13 and second hooks 22 respectively. The hydraulic industrial system is used to simultaneously start several hydraulic telescopic cylinders 51. The hydraulic telescopic cylinders 51 push out the telescopic rod. The telescopic rod pushes the baffle 52 to squeeze the inner wall of the niche. At the same time, the traction equipment starts to pull the rope, which pushes and pulls the entire formwork outward at the same time, thereby pulling the entire formwork out of the cast niche. Finally, the entire construction operation is completed by simply starting the equipment to lift the formwork back.

[0023] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.

6. A method for supporting and dismantling the formwork for the mooring post niche of a pier according to any one of claims 1-5, characterized in that: It includes two implementation methods: formwork support and demolding. The formwork support method includes the following steps: Step 1: The construction workers need to first pour the berth to the height where the niche needs to be set. At this time, the top surface of the berth serves as the foundation platform for subsequent formwork installation. After the foundation is poured, the top surface of the berth is precisely measured and laid out using a total station measuring instrument to determine the installation position of the mooring bollard (8) and the formwork, providing a precise positioning basis for subsequent installation. Step 2: First, use lifting equipment to place the bollard (8) on the top of the berthing pier. During the lifting process, select the lifting point reasonably according to the weight and center of gravity of the bollard (8) to prevent the bollard (8) from shaking or tilting. After lifting to the designated position, fix the bollard (8) firmly on the berthing pier by pre-embedded bolts or welding to ensure that its position is accurate and stable, and provide a reliable benchmark for subsequent template installation. Step 3: Use the lifting equipment to place the two side bottom corner templates (2) on the top of the mooring pier, so that they are located on both sides of the mooring bollard (8). Before hoisting, the surface of the side bottom corner templates (2) needs to be cleaned and inspected to ensure that the template surface is flat, undamaged and the release agent is evenly applied. When placing, according to the positioning line measured and laid out in advance, combined with the positioning marks on the template, the initial positioning is carried out. Then, the verticality, horizontality and position of the template are precisely adjusted using a level and a theodolite to ensure that the template position is accurate. After the position is determined, use bolts to fix the two side bottom corner templates (2) on the mooring pier. During the bolt tightening process, the diagonal tightening method is used to ensure that the template is evenly stressed and to prevent the template from deforming. Step 4: Align the first splicing slots (11) of the two side corner template bodies (1) with the second splicing blocks on both sides of the top template body (3) and insert them. Use bolt sets to fix the two side corner template bodies (1) and the top template body (3) in place. When installing the bolts, tighten them according to the specified torque requirements to ensure the connection is firm. After installation, use lifting equipment to lift them up and align the first connecting blocks (12) at the bottom of the two side corner template bodies (1) with the several second splicing slots (21) on the side bottom corner template body (2) for positioning. After positioning, the construction personnel enter the template and use bolt sets to fix the side corner template bodies (1) and the side bottom corner template bodies (2) in place. When connecting the bolts, follow the corresponding tightening sequence and torque requirements to ensure that the connection of each part of the template is tight. Step 5: Use bolts to further support and fix the side bottom corner templates (2) and top templates (3) on both sides with several diagonal braces (7). The arrangement of the diagonal braces (7) is designed reasonably according to the size and shape of the template and the lateral pressure factors during concrete pouring to form a stable support system. The connection between the diagonal braces (7) and the template and the pier is firm and reliable, ensuring that the template can withstand a large lateral pressure without deformation or displacement during concrete pouring. Step six, finally, just use bolts to fix the back plate between the top template body (3) and the two side bottom corner template bodies (2). Before the back plate is installed, after the back plate is fixed, conduct a comprehensive inspection of the entire template system, including whether the template connection is firm, whether the support is stable, and whether the size meets the design requirements. After the overall template installation is completed, the construction personnel need to install the template for the remaining part of the berthing pier on the top of the berthing pier and carry out the final pouring operation of the main body of the berthing pier. The demolding method includes the following steps: Step 1: After the overall casting of the pier is completed and other formwork is removed, the concrete reaches a certain strength. At this time, the formwork removal operation of this device is carried out. First, the construction personnel enter the formwork to remove several bolt groups that fix the back formwork body (4). During the removal process, the bolts are loosened in a certain order to prevent the back plate from being damaged due to uneven force. Several wooden strips (40) of the back formwork body (4) are removed one by one and taken out from the formwork. After all of them are taken out, they are cleaned and inspected for future use. Step 2: Connect the pipeline of the hydraulic supply system to the interfaces of several hydraulic telescopic cylinders (51). After the construction personnel come out, use traction equipment and lifting equipment to fix them to several first hooks (13) and second hooks (22). Use the hydraulic supply system to start several hydraulic telescopic cylinders (51) at the same time. The hydraulic telescopic cylinders (51) push out the telescopic rod, and the telescopic rod pushes the baffle (52) to squeeze the inner wall of the niche. In this process, the hydraulic system controls the thrust and extension speed of the telescopic cylinder to ensure that the template is subjected to uniform force and is smoothly removed from the niche. At the same time, the traction equipment starts to pull the rope, and pushes and pulls the template outward at the same time. Through the synergistic effect of hydraulic thrust and mechanical pull, the bonding force between the concrete and the template is overcome, and the template is pulled out of the completed niche. Step three: The entire construction operation can be completed simply by lifting the formwork back using hoisting equipment. After the formwork is lifted back, it should be thoroughly cleaned, repaired, and maintained. Check whether each part of the formwork is intact, and replace or repair any damaged parts to prepare it for the next use.
