Description

Technical Field

[0001] This utility model belongs to the field of construction technology of ship locks in waterway engineering, and in particular relates to a support and reinforcement device for building foundation construction. Background Technology

[0002] Ship locks, as key navigation structures on river waterways, are typically located within water conservancy projects. Their upper lock heads serve both flood control and flood discharge functions, making them typical large-scale water conservancy projects. Ship lock chambers are enormous in size, long and wide, and are divided longitudinally into multiple segments with identical structural designs. Faced with such large-scale cast-in-place concrete construction, formwork trolleys are currently widely used instead of traditional scaffolding for construction.

[0003] Formwork trolleys include Bailey bridge truss trolleys and steel frame truss trolleys. Bailey bridge truss trolleys use Bailey bridge panels for their crossbeams and columns, resulting in lower overall strength, rigidity, and stability compared to steel frame truss trolleys. When suspending large sections of steel formwork, the upper crossbeams are prone to deformation. Steel frame truss trolleys typically use electric or manual hoists in conjunction with tensioners to open and close the formwork. However, the formwork movement cannot be synchronized, easily causing distortion or deformation of the formwork plane. Furthermore, using manual hoists for opening and closing the formwork is labor-intensive, inefficient, and economically unprofitable.

[0004] To reduce labor intensity and improve construction efficiency, existing technologies utilize hydraulic formwork trolleys. However, these trolleys lack independent, fine-tuning mechanisms for the formwork's planar position, resulting in limitations such as limited adjustment functions, poor positioning accuracy, difficulty in demolding, and easy cracking of concrete. Furthermore, the gantry system suffers from insufficient structural strength, often employing single-frame structures with weak lateral and longitudinal connections and insufficient effective spatial support between columns. Under the lateral pressure of concrete and wind loads, excessive deflection or torsion occurs, causing the formwork elevation and planar position to deviate from the design. Consequently, the cast-in-place gate walls exhibit misalignment and wavy surfaces, requiring extensive repairs later on. Utility Model Content

[0031] To better understand the above technical solutions, the following is in conjunction with the appendix. Figures 1-10 The specific implementation methods are described in detail below for the above technical solutions.

[0032] refer to Figure 1 In one illustrative embodiment of the hydraulic formwork trolley 10 for the construction of lock chamber walls of this utility model, the hydraulic formwork trolley 10 includes a gantry system 1, a traveling system 2, a hydraulic system 4, and a formwork system 3.

[0033] refer to Figure 1 , Figure 3 The traveling system 2 is located at the bottom of the lower longitudinal beam 11 below the gantry system 1, and is used to move the gantry system 1 so that the gantry system 1 can be quickly and flexibly adjusted in position according to construction needs.

[0034] Template system 3 is installed on both sides of the lock chamber, and template system 3 includes inner mold 31 and outer mold 32. (Reference) Figure 8 , Figure 9 The diagram shows the assembly of the outer and inner molds. The inner mold 31 and the outer mold 32 form a molding cavity for pouring concrete for the lock chamber wall. The inner mold 31 and the outer mold 32 can be made of large steel formwork, enabling the lock chamber wall to be poured to the top in one go.

[0035] In this embodiment, the formwork system 3 is suspended from the upper longitudinal beam 12 of the gantry system 1, making the formwork system 3 more stable during construction and able to withstand the lateral pressure during concrete pouring. At the same time, the suspension connection facilitates the installation and dismantling of the formwork system 3, improving construction flexibility and efficiency, and reducing the installation and dismantling time.

[0036] The hydraulic system 4 is installed on the gantry system 1 and is mainly used to provide power for the opening and closing of the formwork system 3. The hydraulic system 4 is characterized by strong power, simple operation and high control precision, which can ensure that the opening and closing action of the formwork system 3 is accurate and fast, improve construction efficiency, reduce the error of manual operation, and at the same time ensure the service life of the formwork system 3.

[0037] Specifically, the hydraulic system 4 includes a lifting cylinder 41, which is mounted on the lower longitudinal beam 11 and is used to lift the gantry system 1 to adjust the elevation of the formwork system 3. This arrangement allows the elevation of the formwork system 3 to be precisely adjusted according to the design height of the lock chamber wall, thereby improving construction accuracy and quality.

[0038] In this embodiment, reference Figure 3 The inner sleeve 411 of the lifting cylinder 41 is mounted on the lower longitudinal beam 11.

[0039] refer to Figure 2 The hydraulic system 4 also includes a translation cylinder, which is installed on the top of the gantry system 1 and is used to push the upper longitudinal beam 12 to adjust the planar position of the inner mold 31 and the outer mold 32 of the template system 3.

[0040] The installation of the translation cylinder ensures the accurate planar position of the formwork system 3, so that the planar position of the wall after concrete pouring meets the design requirements and improves the construction quality.

[0041] The hydraulic system 4 also includes an internal demolding cylinder 44. The internal mold 31 is connected to the column 14 of the gantry system 1 via the internal demolding cylinder 44, which assists the internal mold 31 in demolding. (Reference) Figure 9 The area within the cloud-lined frame in the inner mold assembly diagram indicates the installation location of the inner demolding cylinder.

[0042] The hydraulic system 4 also includes an external demolding cylinder 45, which is mounted on top of the gantry system 1. The external demolding cylinder 45 is connected to the bottom of the outer side of the outer mold 32, and can assist the outer mold 32 in demolding.

[0043] The lifting cylinder 41, the translation cylinder, the inner demolding cylinder 44, and the outer demolding cylinder 45 are connected to the same hydraulic station, which can realize the precise opening and closing of the template.

[0044] In this embodiment, by setting up a lifting cylinder 41, a translation cylinder, an inner demolding cylinder 44, and an outer demolding cylinder 45, flexible adjustment of the elevation of the template system 3 and the planar positions of the inner mold 31 and outer mold 32 is achieved. This simplifies the demolding operation, improves construction efficiency, reduces labor intensity, and makes the construction of the lock chamber wall more convenient and efficient. Furthermore, all cylinders are connected to the same hydraulic station, ensuring synchronized movement of the template. This solves the technical problem in existing technologies where using electric hoists or hand-operated hoists in conjunction with tensioners to open and close the template easily causes distortion or deformation of the template plane.

[0045] In some embodiments of this application, reference is made to Figure 1 The hydraulic template trolley 10 also includes a safety protection system 6.

[0046] By incorporating safety protection system 6, the safety of the hydraulic formwork trolley 10 during construction is enhanced. It effectively prevents construction workers from accidentally falling or coming into contact with dangerous areas, protecting their personal safety, reducing the occurrence of accidents, and also helps maintain order at the construction site, ensuring the smooth progress of the construction process.

[0047] refer to Figure 7 The safety protection system 6 includes a construction guardrail 51, which is located on the outside of the outer formwork 32, the inside of the inner formwork 31, and the top and ends of the gantry system 1.

[0048] In this embodiment, the multi-directional arrangement of the construction guardrail 51 forms a comprehensive safety protection network, providing all-round safety protection for construction workers, greatly reducing construction risks, and ensuring the personal safety of construction workers.

[0049] Safety protection system 6 also includes a work ladder 52, which is located between the column 14 and the inner mold 31. In some embodiments of this application, the translation cylinder includes an inner translation cylinder 43, which is used to adjust the planar position of the inner mold 31.

[0050] The translation cylinder also includes an outer translation cylinder 42, which is used to adjust the planar position of the outer mold 32.

[0051] In this embodiment, the translation cylinder is divided into an inner translation cylinder 43 and an outer translation cylinder 42, which are used to adjust the planar position of the inner mold 31 and the outer mold 32 respectively, so that the template position adjustment is more precise and independent, which can better meet the requirements of the lock chamber wall construction for the template position accuracy, thereby improving the construction quality.

[0052] Furthermore, the template system 3 also includes end templates, which are located between the ends of the inner mold 31 and the outer mold 32. During installation of the template system 3, the lifting cylinder 41 first lifts the gantry system 1 to adjust the elevation, ensuring it meets the requirements of the drawings and specifications. After the elevation adjustment is in place, the inner mold 31 is coarsely adjusted by pushing it with the inner translation cylinder 43; then, the outer translation cylinder 42 pushes the upper longitudinal beam 12 at the top to coarsely adjust the outer mold 32. After the coarse adjustments of the inner mold 31 and outer mold 32 are completed, the templates are finely adjusted, and finally, the end templates are installed, thus completing the installation of the template system 3.

[0053] In some embodiments of this application, the various components of the gantry system 1 can be fixed by bolt connection.

[0054] In this embodiment, all components of the gantry system 1 can be quickly assembled and disassembled without the need for on-site welding. Compared to the existing Bailey frame formwork trolleys and steel bracket formwork trolleys, which are assembled by welding, this method is beneficial for the subsequent modification of formwork trolleys for the construction of lock chamber walls in Level 2 and Level 3 ship locks, increasing the number of formwork turnovers and reducing construction costs.

[0055] refer to Figure 4 The gantry system 1 includes multiple gantry beams 131 and multiple columns 14. There are two symmetrically arranged lower longitudinal beams 11, and the multiple columns 14 are arranged in two rows on the lower longitudinal beams 11.

[0056] The two lower longitudinal beams 11 provide two parallel stress baselines, ensuring symmetrical and stable movement and load transfer of the hydraulic trolley. The column 14 and the lower longitudinal beams 11 can be connected by bolts.

[0057] refer to Figure 5 Multiple columns 14 in the same row are connected by longitudinal connecting beams 151 to connect the single column 14 into a longitudinal whole, which significantly enhances the longitudinal stiffness of the gantry and reduces the out-of-plane deformation of the column 14.

[0058] The bottom of the gantry beam 131 is fixedly connected to the columns 14 on both sides with first diagonal braces 161. The first diagonal braces 161 form a triangular stable structure between the beam and the columns 14, which effectively resists horizontal shear force and vertical bending moment and reduces stress concentration at the nodes.

[0059] The first diagonal brace 161 is bolted to the gantry beam 131 and the column 14 at both ends. The bolted joints make the first diagonal brace 161 easy to assemble and disassemble, and the angle of the first diagonal brace 161 can be quickly adjusted or different specifications can be replaced according to the stress requirements, thus improving on-site adaptability.

[0060] A second crossbeam 132 connects the first diagonal brace 161, and two vertical beams 17 are provided between the second crossbeam 132 and the portal frame crossbeam 131. (Reference) Figure 4 The second crossbeam 132, together with the double vertical beams 17, forms a local small frame, which further shares the load of the portal frame crossbeam 131 and reduces the span of the crossbeam, thereby reducing the cross-sectional dimensions and steel consumption of the portal frame crossbeam 131.

[0061] A second diagonal brace 162 is provided between the two opposite sides of the vertical beams 17 and the second horizontal beam 132. The second diagonal brace 162 forms a secondary triangular support between the vertical beams 17 and the second horizontal beam 132, which improves the local torsional stiffness and suppresses the swaying of the formwork trolley during operation.

[0062] In this embodiment, the second crossbeam 132 is fixed to the first diagonal brace 161 and the gantry crossbeam 131 by bolts, and the vertical beam 17 is fixed to the second diagonal brace 162 and the second crossbeam 132 support by bolts.

[0063] By setting up multiple portal frame beams 131, columns 14, first diagonal braces 161, second portal beams 132, vertical beams 17, and second diagonal braces 162, a stable portal frame system 1 is formed. This structure enhances the overall stability and load-bearing capacity of the portal frame system 1, effectively resisting the effects of various external forces during construction, and ensuring the stability and accuracy of the construction process.

[0064] In some embodiments of this application, reference is made to Figure 6 Multiple gantry beams 131 are connected by horizontal connecting beams 18, the downward projection of which lies between the two columns 14. The horizontal connecting beams 18 connect the gantry beams 131 into a whole, further enhancing the structural strength.

[0065] In this embodiment, the horizontal connecting beam 18 can be fixedly connected to the gantry beam 131 by bolts.

[0066] Both ends of the gantry beam 131 extend to the outside of the column 14 to form cantilever ends, and upper longitudinal beams 12 are provided at the cantilever ends for suspending the formwork system 3. The cantilever ends and the upper longitudinal beams 12 cooperate to form an extended suspension platform, which allows the formwork system 3 to be operated simultaneously on both sides of the gate chamber wall, expanding the construction area and improving the efficiency of wall pouring.

[0067] In this embodiment, a horizontal connecting beam 18 is used to connect multiple gantry beams 131, with the projection of the horizontal connecting beam 18 located between two columns 14. Simultaneously, both ends of the gantry beams 131 are extended to form cantilever ends, and upper longitudinal beams 12 are installed at the cantilever ends to suspend the formwork system 3. This structure enhances the connection strength and overall integrity between the gantry beams 131, improves the stability of the gantry system 1, and also provides more stable suspension connection points for the formwork system 3, ensuring the stability of the formwork system 3 during construction.

[0068] In some embodiments of this application, a vertical connecting beam 153 is connected between the first diagonal brace 161 and the gantry beam 131, and the vertical connecting beam 153 is connected to the column 14 through a horizontal connecting beam 152 and a diagonal connecting beam 154.

[0069] The vertical connecting beam 153, the column 14, and the diagonal connecting beam 154 of the column are fixed together by bolts.

[0070] In this embodiment, a vertical connecting beam 153 is connected between the first diagonal brace 161 and the gantry beam 131, and the vertical connecting beam 153 is connected to the column 14 through the horizontal connecting beam 152 and the diagonal connecting beam 154, which further strengthens the connection strength between the components of the gantry system 1, improves the structural strength and stability of the entire gantry system 1, and enables it to better withstand various loads during construction.

[0071] In some embodiments of this application, reference is made to Figure 5 A third diagonal brace 163 is provided between adjacent columns 14, and the third diagonal brace 163 is located between the longitudinal connecting beams 151 of the two columns.

[0072] The third diagonal brace 163 forms an additional support between adjacent columns 14, reducing the free length of the columns 14 and preventing the columns 14 from buckling outwards.

[0073] Continue to refer to Figure 5 Along the length of the longitudinal connecting beam 151 of the column, multiple third diagonal braces 163 are arranged in an X-shape, forming a two-way shear truss, which significantly improves the longitudinal lateral stiffness of the gantry.

[0074] In this embodiment, a third diagonal brace 163 in an X-shape is provided between adjacent columns 14, which enhances the connection stability between adjacent columns 14, improves the overall deformation resistance of the gantry system 1, and further optimizes the structural performance of the gantry system 1, making it more stable and reliable during construction.

[0075] In some embodiments of this application, fourth diagonal braces 164 are provided between the gantry beams 131, and a plurality of fourth diagonal braces 164 are symmetrically arranged along the longitudinal centerline L of the gantry system 1. (See reference...) Figure 6 The fourth diagonal brace 164 on one side of the longitudinal centerline L is located between the adjacent horizontal connecting beams 18.

[0076] In some embodiments of this application, a construction platform 6 is reserved on the top of the outer mold 32 for integral casting of the cable trough and the gate chamber wall. Integral casting of the cable trough and the gate chamber wall shortens the construction period and reduces construction costs.

[0077] The cable trough is a cantilever structure, and the construction platform 6 facilitates the pouring of the cable trough and the gate chamber wall.

[0078] Multiple sets of spaced steel supports are detachably erected on the construction platform 6, and support plates are laid on the steel supports to form the working surface of the construction platform 6.

[0079] The combination of steel frame and support plate makes the construction platform 6 more flexible and can meet different construction needs.

[0080] For example, in this embodiment, the spacing between the steel brackets is 650mm, and the support plate includes imitation wood and thick bamboo plywood. A 5cm×8cm imitation wood panel and a 1.5cm thick bamboo plywood panel are laid on top of the steel brackets, and finally, the cable trough reinforcement is tied.

[0081] In some cases, the steel wire ropes of the suspended formwork pass through the cable trough, which can be sealed using the suspended formwork method before backfilling behind the wall, thus improving the convenience and efficiency of construction.

[0082] In some embodiments of this application, reference is made to Figure 3 The walking system 2 includes steel rails 21 and walking wheel sets 22. There are two steel rails 21 arranged symmetrically and fixed to the ground by bolts. The walking wheel sets 22 are set on the steel rails 21, and the walking wheel sets 22 on the two steel rails 21 move synchronously.

[0083] By employing at least four sets of powered walking mechanisms, the heavy-duty formwork trolley can be guaranteed to travel smoothly and accurately along the steel rail 21, preventing construction errors or safety hazards caused by asynchronous walking.

[0084] In this embodiment, the motor power of the walking wheel assembly 22 is 7.5 kW, the walking speed is 3~5 m / min, the walking wheel assembly 22 adopts chain and sprocket drive, and uses a high-efficiency cycloidal pinwheel reducer. The walking system 2 uses a single cable and a single switch for control, ensuring synchronization of the walking motors on both sides.

[0085] In some embodiments of this application, reference continues to be made to Figure 3The gantry system 1 also includes several top supports 19, which are used to support the bottom of the lower longitudinal beam 11.

[0086] In this embodiment, several top supports 19 are provided at the bottom of the lower longitudinal beam 11 of the gantry system 1. These top supports 19 effectively support the lower longitudinal beam 11, enhance its load-bearing capacity, and prevent it from deforming or sinking during construction. At the same time, the top supports 19 facilitate the lifting cylinder 41 to adjust the height of the formwork system 3, ensuring the overall stability and construction accuracy of the gantry system 1.

[0087] In some embodiments of this application, the template system 3 further includes a ladder template 33 and a floating bollard template 34.

[0088] The floating bollard template 34 is optimized to have rounded corners. The floating bollard template 34 is connected in the middle by screw rods. The reinforcement and removal of the floating bollard template 34 are achieved by tightening and loosening the screw rods.

[0089] In this embodiment, the floating mooring bollards are constructed using a one-time casting process. Channel steel is used to fix the floating mooring bollard tracks at the fabrication yard, and then the bollards are transported to the construction site for overall hoisting. The floating mooring bollard formwork 34 is installed before the floating mooring bollard tracks are installed.

[0090] The floating mooring bollard formwork 34 and its track do not move synchronously with the hydraulic formwork trolley 10. They can be installed after the steel reinforcement of the lock chamber wall is tied.

[0091] This utility model proposes a hydraulic formwork trolley 10 for the construction of lock chamber walls. Utilizing a hydraulic system 4, it achieves integrated reinforcement, dismantling, movement, and lifting of the inner formwork 31 and the outer formwork 32, greatly improving construction efficiency. Furthermore, all cylinders in the hydraulic system 4 are uniformly controlled by a central hydraulic station, improving the installation accuracy of the formwork system 3 compared to traditional hand-operated hoists and electric hoists for opening and closing the formwork.
