Description

Technical Field

[0001] This utility model relates to the technical field of building construction formwork, and in particular to a steel formwork for a platform wall with a drainage ditch that can be freely disassembled and assembled. Background Technology

[0002] In the construction of platforms for transportation projects such as railways and highways, platform walls with drainage ditches are a common structure. These walls are located at the edge of the platform and serve functions such as separating areas, bearing loads, and providing drainage. When constructing platform walls with drainage ditches, formwork is required to shape the concrete pouring. Among various formwork materials, steel formwork is a commonly used choice due to its high strength, high rigidity, and smooth surface.

[0003] Existing platform wall steel formwork is typically an integral or fixed-connection structure. During installation and dismantling, integral formwork requires large hoisting equipment, is complex to operate, and consumes significant manpower and time. Fixed-connection formwork is difficult to adjust in size and flexibly combine to meet different construction needs, resulting in poor versatility and increased construction costs. Therefore, a freely detachable and combinable platform wall steel formwork with drainage ditches is needed to improve construction efficiency, reduce costs, and ensure the construction quality of both the platform wall and the drainage ditches. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steel formwork for a platform wall with a drainage ditch that can be freely disassembled and assembled, which is flexible to adapt to different construction needs, has a firm connection and good sealing, and is easy to operate.

[0005] This utility model discloses a freely detachable and combinable steel formwork for a platform wall with a drainage ditch, comprising multiple platform wall formwork units and multiple drainage ditch formwork units; the platform wall formwork unit includes a wall body formwork and a wall bottom formwork, the bottom of the wall body formwork and the wall bottom formwork are detachably connected, and the wall body formwork and the wall bottom formwork are connected by reinforcing ribs through connectors; the drainage ditch formwork unit includes a drainage ditch sidewall formwork and a drainage ditch bottom formwork, the drainage ditch sidewall formwork and the drainage ditch bottom formwork are detachably connected.

[0006] Furthermore, the platform wall formwork unit and the drainage ditch formwork unit are connected by a first mating tenon and a first mating mortise. The shapes of the first mating tenon and the first mating mortise are compatible, and a sealing rubber strip is provided on their contact surface.

[0007] Furthermore, a quick-release assembly is provided at the connection between the wall body template and the wall bottom template. The quick-release assembly includes a U-shaped clip and a U-shaped groove. The U-shaped clip is set on the wall body template, and the U-shaped groove is set on the wall bottom template. The open end of the U-shaped clip and the U-shaped groove are rotatably connected by a pin, and a tightening nut is provided at the closed end of the U-shaped clip.

[0008] Furthermore, the connecting ends of the side wall template and the bottom template of the ditch are provided with lifting protrusions and lifting grooves, which cooperate with each other, and a handle is provided on the lifting protrusion.

[0009] Furthermore, the ditch sidewall template includes an inner template and an outer template, which are connected by an adjustable telescopic assembly. The adjustable telescopic assembly includes an adjusting rod and an adjusting sleeve fitted on the adjusting rod. One end of the adjusting rod is fixed to the inner template, and the adjusting sleeve is fixed to the outer template. An adjusting nut is provided on the adjusting sleeve.

[0010] Furthermore, ventilation holes are evenly distributed on the bottom template of the ditch.

[0011] Furthermore, the surfaces of both the platform wall formwork unit and the drainage ditch formwork unit are coated with a release oil layer.

[0012] Furthermore, adjacent drainage ditch template units are connected by a second tenon and a second mortise. The shapes of the second tenon and the second mortise are compatible, and a positioning protrusion is provided on the second tenon, while a positioning groove is provided in the second mortise.

[0013] Furthermore, the platform wall formwork units are positioned by positioning columns and positioning sleeves. The positioning columns are set on the side of one platform wall formwork unit, and the positioning sleeves are set on the opposite sides of adjacent platform wall formwork units. The positioning columns and positioning sleeves are fitted with a clearance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The wall formwork and bottom formwork in the platform wall formwork unit are detachably connected, and the side wall formwork and bottom formwork in the ditch formwork unit are detachably connected. Appropriate connection methods are used between the platform wall formwork unit and the ditch formwork unit, between adjacent platform wall formwork units, and between adjacent ditch formwork units.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] like Figures 1 to 6 As shown, this utility model discloses a freely detachable and combinable steel formwork for a platform wall with a drainage ditch, comprising multiple platform wall formwork units 1 and multiple drainage ditch formwork units 2. The platform wall formwork unit 1 includes a wall body formwork 11 and a wall bottom formwork 12, with the bottom of the wall body formwork 11 detachably connected to the wall bottom formwork 12. The wall body formwork 11 and the wall bottom formwork 12 are connected by reinforcing ribs via connectors. The drainage ditch formwork unit 2 includes a drainage ditch sidewall formwork 21 and a drainage ditch bottom formwork 22, which are detachably connected.

[0027] By disassembling the formwork for the platform wall and drainage ditch into multiple independent units, these units can be freely combined and disassembled during construction. During assembly, the bottom of the wall formwork 11 and the bottom wall formwork 12 combine to form a complete platform wall formwork, while the side wall formwork 21 and the bottom formwork 22 of the drainage ditch combine to form a complete drainage ditch formwork. Reinforcing ribs enhance the formwork's strength and stability to withstand the pressure and loads during concrete pouring. The freely detachable and combinable design eliminates the need for large hoisting equipment like with monolithic formwork, simplifying operation and significantly reducing time and manpower spent on installation and disassembly, thus improving construction efficiency. Furthermore, the formwork can be adjusted in size and flexibly combined according to different construction needs, adapting to the construction of platform walls with drainage ditches of different specifications and shapes. Compared to fixed and difficult-to-adjust formwork, its versatility is significantly improved, allowing one set of formwork to be used in various construction scenarios, reducing the cost of custom-made formwork for different construction needs. The disassembled formwork units are small in size, facilitating transportation and storage, saving space and costs associated with transportation and storage.

[0028] The platform wall formwork unit 1 and the drainage ditch formwork unit 2 are connected by a first tenon 15 and a first mortise and tenon joint. The shapes of the first tenon 15 and the first mortise and tenon joint are compatible, and a sealing rubber strip is provided on their contact surface. The tenon and tenon structure of the first tenon 15 and the first mortise and tenon joint enables the two formwork units to be precisely connected, enhancing the tightness and stability of the connection. During the concrete pouring process, it can effectively prevent problems such as formwork bulging and grout leakage caused by loosening of the formwork connection, ensuring the stability of the overall formwork structure under construction load, and thus ensuring the construction quality of the platform wall with drainage ditch. The sealing rubber strip has good elasticity and compression deformation capacity. When the first tenon 15 is inserted into the first mortise and tenon joint, the rubber strip is squeezed and undergoes elastic deformation, tightly fitting the contact surface of the tenon and the mortise and tenon joint, thereby preventing liquid from seeping through the gaps in the contact surface.

[0029] A quick-release assembly is preferably provided at the connection between the wall formwork 11 and the wall base formwork 12. The quick-release assembly includes a U-shaped locking block 16 and a U-shaped slot 17. The U-shaped locking block 16 is set on the wall formwork 11, and the U-shaped slot 17 is set on the wall base formwork 12. The open end of the U-shaped locking block 16 and the U-shaped slot 17 are rotatably connected by a pin 18, and a tightening nut 19 is provided at the closed end of the U-shaped locking block 16. The pin 18 serves as a rotation axis, allowing the U-shaped locking block 16 to rotate freely within a certain angle range around the pin 18. When it is necessary to connect the wall formwork 11 and the wall base formwork 12, the construction worker rotates the U-shaped locking block 16 to engage with the U-shaped slot 17. 7. Align and insert the U-shaped blocks 16 and U-shaped slots 17 into each other to achieve the initial connection and positioning of the wall formwork 11 and the wall base formwork 12. Rotate the tightening nut 19 with a tool. Under the action of the threads on the U-shaped blocks 16, the tightening nut 19 moves along the thread direction. As the tightening nut 19 moves, it generates a pressure perpendicular to the surface of the U-shaped slot 17, which increases the friction between the U-shaped blocks 16 and the U-shaped slot 17, thereby tightly connecting the wall formwork 11 and the wall base formwork 12 together, resisting various external forces generated during concrete pouring, and ensuring the stability of the formwork connection.

[0030] The preferred connection ends of the sidewall formwork 21 and bottom formwork 22 of the ditch are provided with lifting protrusions 221 and lifting grooves 222. The lifting protrusions 221 and lifting grooves 222 cooperate with each other, and a handle is provided on the lifting protrusions 221. The lifting protrusions 221 and lifting grooves 222 are connected by the principle of convex-concave fit in mechanical structure. This mechanical fit can withstand a certain external force and maintain the stability of the formwork connection during concrete pouring. The handle provides a point of force for construction personnel to apply external force. By pulling the lifting protrusions 221 with the handle, the lifting protrusions 221 overcome the friction between themselves and the lifting grooves 222 and the possible initial resistance under the action of the pulling force, and smoothly embed themselves into the lifting grooves 222. At the same time, during disassembly, the reverse pulling force can help overcome the adhesive force generated at the formwork connection due to concrete solidification and other reasons, so as to achieve rapid separation of the formwork. The presence of the handle allows construction personnel to more effectively control the force during the connection and disassembly process, ensuring smooth operation.

[0031] The preferred drainage ditch sidewall template 21 includes an inner template 211 and an outer template 212, which are connected by an adjustable telescopic assembly 213. The adjustable telescopic assembly 213 includes an adjusting rod 2131 and an adjusting sleeve 2132 sleeved on the adjusting rod 2131. One end of the adjusting rod 2131 is fixed to the inner template 211, and the adjusting sleeve 2132 is fixed to the outer template 212. An adjusting nut 2133 is provided on the adjusting sleeve 2132. When the adjusting nut 2133 is rotated, since the adjusting nut 2133 is threadedly connected to the adjusting sleeve 2132, the rotation of the adjusting nut 2133 is converted into the adjusting sleeve 2132 moving along the adjusting rod 2131. The linear movement of the adjusting sleeve 2132 changes the distance between the inner template 211 and the outer template 212, thereby adjusting the width of the ditch sidewall template. This design allows the same template to be used for the construction of ditches of different sizes and specifications, improving the versatility of the template and reducing the cost of customizing templates for different projects. After the adjusting sleeve 2132 moves to the appropriate position, the adjusting nut 2133 is rotated. The adjusting nut 2133 will press tightly against the adjusting rod 2131 under the action of the thread, thereby locking the position of the adjusting sleeve 2132. This ensures that the adjusting sleeve 2132 will not move arbitrarily due to external forces during the concrete pouring process, ensuring the dimensional stability of the template after adjustment.

[0032] The preferred bottom template 22 of the drainage ditch is evenly provided with ventilation holes 223; when pouring concrete, the air in the concrete is discharged; if the template is not breathable, the air will be trapped inside the concrete and will form air on the concrete surface. Through the discharge channel provided by the ventilation holes 223, the surface of the poured concrete is made smoother and flatter, reducing surface defects caused by air bubbles and improving the appearance quality of the concrete structure.

[0033] Both the preferred platform wall formwork unit 1 and the drainage ditch formwork unit 2 are coated with a release oil layer. As a physical isolation medium, the release oil layer forms a physical barrier between the formwork and the concrete. When the concrete is poured into the formwork, this oil film prevents the cement paste and other components in the concrete from directly contacting the formwork surface, thereby reducing the adhesion between the two and achieving effective isolation between the formwork and the concrete, creating favorable conditions for subsequent demolding work.

[0034] Preferably, adjacent ditch template units 2 are connected by a second tenon 23 and a second tenon groove 24. The shapes of the second tenon 23 and the second tenon groove 24 are compatible, and the second tenon 23 is provided with a positioning protrusion, while the second tenon groove 24 is provided with a positioning groove. The second tenon 23 and the second tenon groove 24 can fit tightly together when connected, providing a strong mechanical interlocking effect. This tight fit can effectively resist the lateral pressure generated during concrete pouring and other construction loads, ensuring that there will be no loosening or displacement between adjacent ditch template units 2, and ensuring the stability of the entire ditch template structure during construction. The positioning protrusion and the positioning groove cooperate with each other to provide positioning for the installation of the template. Precise positioning ensures the overall flatness and straightness of the ditch template after splicing, avoiding ditch forming quality problems caused by template installation deviations, such as uneven ditch walls and inconsistent ditch widths.

[0035] The preferred platform wall template units 1 are positioned using positioning posts 3 and positioning sleeves 4. Positioning posts 3 are located on the side of one platform wall template unit 1, and positioning sleeves 4 are located on the opposite sides of adjacent platform wall template units 1. The positioning posts 3 and positioning sleeves 4 are fitted with a clearance fit. This design ensures that the positioning posts 3 can be smoothly inserted into the positioning sleeves 4 while precisely defining the relative positions of adjacent platform wall template units 1. Horizontally, the clearance fit ensures tight contact between the positioning posts 3 and the inner walls of the positioning sleeves 4, effectively preventing lateral shifts during template unit assembly and ensuring that all platform wall template units are aligned on a straight line, guaranteeing the overall flatness of the platform wall. Vertically, this positioning method precisely controls the height difference between template units, preventing misalignment, improving the construction accuracy of the platform wall, and providing a good foundation for subsequent platform surface paving and related facility installation.

[0036] This utility model discloses a freely detachable and assembleable steel formwork for a platform wall with a drainage ditch. During assembly, the bottom of the wall formwork 11 is first connected to the bottom wall formwork 12 via connectors, and quick-release components are installed at the connection between the wall formwork 11 and the bottom wall formwork 12. When assembling the drainage ditch formwork unit 2, the inner formwork 211 and outer formwork 212 are adjusted to a suitable spacing using telescopic components 213 to form a drainage ditch sidewall formwork 21 that meets the design width requirements. Then, the drainage ditch sidewall formwork 21 is connected to the drainage ditch bottom formwork 22. Adjacent drainage ditch formwork units 2 are connected via second tenons 23 and second mortises 24. The fit between the positioning protrusions and positioning grooves, and between the positioning posts 3 and positioning sleeves 4, is checked to ensure accurate splicing. Throughout the entire formwork assembly process... The platform wall template units 1 are connected by the first tenon 15 and the first tenon groove. Adjacent template units are accurately spliced ​​by the positioning column 3 and the positioning sleeve 4. After the construction of the platform wall and the ditch is completed, the connecting parts of the wall template 11 and the bottom template 12 are loosened first. Then, using the quick-release assembly, the pin 18 is rotated to make the U-shaped clip 16 rotate out of the U-shaped clip 17, so that the wall template 11 and the bottom template 12 can be separated. When disassembling the ditch template unit 2, the construction personnel first hold the handle on the lifting protrusion 221 to lift the ditch side wall template 21 from the bottom template 22 of the ditch. Then, the connection of the adjusting telescopic assembly 213 is disassembled, so that the ditch template unit 2 can be separated into the inner template 211 and the outer template 212. Finally, the bottom template 22 of the ditch is removed.

[0037] This utility model discloses a freely detachable and combinable steel formwork for a platform wall with a drainage ditch. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
