Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a pouring platform device for pile foundations. Background Art

[0002] Currently, conventional pile foundation grouting platforms typically use two sleepers placed symmetrically around the steel casing as the cage's load-bearing device. When lowering the cage, a beam passes through the cage, placing the entire cage's weight on the sleepers on either side of the casing. If the sleepers tilt or settle due to uneven force, the cage will become misaligned within the hole. Severely tilted or settled sleepers can also cause the cage's top elevation to be inaccurate, leading to significant fluctuations in pile top elevation and large pile position deviations after excavation, among other pile foundation construction issues. Utility Model Content

[0003] The purpose of this application is to provide a pouring platform device for pile foundation to solve at least one technical problem existing in the prior art.

[0004] In order to solve the above technical problems, the present application provides a pouring platform device for pile foundation, comprising a steel casing, a platform body, a steel cage, a supporting bar and a support block;

[0005] The steel casing is a cylindrical outer cylinder with upper and lower openings;

[0006] The steel casing is arranged in the pile hole to prevent surface water or other debris from entering the steel casing and affecting the construction;

[0007] The height of the steel casing exceeds the ground;

[0008] The platform body is arranged on the ground and is located above the pile hole;

[0009] The platform body is provided with a side slot for arranging the support block;

[0010] The support block is inserted into or removed from the side slot from the side of the platform body;

[0011] The upper end of the support block is higher than the upper surface of the platform body;

[0012] The upper end surface of the support block is provided with a slot that matches the size and shape of the carrying pole;

[0013] The steel cage is placed in the pile hole by hoisting;

[0014] When the steel cage is hoisted to a predetermined height, the steel cage is erected on the carrying bar by inserting the carrying bar;

[0015] The carrying bar is arranged in the slot of the supporting block.

[0016] Furthermore, the platform body includes an outer support frame and an inner support frame;

[0017] The outer support frame is a quadrilateral structure;

[0018] The inner support frame is arranged on two adjacent frame bodies of the outer support frame to increase the overall strength of the platform body and prevent construction deviation caused by deformation.

[0019] Furthermore, the outer support frame and the inner support frame are connected by welding or integrally formed.

[0020] Furthermore, lifting ears are provided on the diagonals of the platform body for lifting the platform body to the construction location by means of lifting equipment.

[0021] Furthermore, the side wall of the side slot is a concave-convex structure, and the side wall of the support block is a concave-convex structure matching the side slot structure, which is used to limit the position of the support block.

[0022] Furthermore, a limiting cam is provided at one end of the side slot close to the steel casing, and a limiting slot is provided at the other end, and a limiting plate is provided in the limiting slot;

[0023] By providing the limiting clamping protrusion and the limiting plate, the position of the support block in the horizontal direction is limited, thereby avoiding deviation in construction caused by displacement of the support block during construction.

[0024] Furthermore, the slot is a slot body with a large opening at the upper end and a small opening at the lower end, and the side wall of the slot body is a straight wall plane;

[0025] The shapes of the lower parts from both ends of the shoulder bar to the joints between the shoulder bar and the trough body are consistent with the shape of the trough body. The other parts of the shoulder bar are rectangular, which is used to displace the shoulder bar in the horizontal direction relative to the support block, resulting in deviations in construction.

[0026] Furthermore, the steel cage inside the steel casing is provided with a plurality of steel cages;

[0027] A plurality of the steel cages are arranged and connected in the axial direction.

[0028] Furthermore, a suspension bar is provided at the upper end of the uppermost reinforcement cage;

[0029] The lower end of the suspension bar is connected to the top of the steel cage, and the other end is bent into a suspension ring;

[0030] Before pouring concrete, the carrying bar passes through the lifting ring so that the steel cage is hung under the carrying bar.

[0031] Furthermore, a hanging groove is opened at the position of the carrying bar corresponding to the hanging ring, so that the steel cage is located in the middle of the pile hole when it is hung under the carrying bar, and the position of the steel cage is prevented from deviating when pouring concrete.

[0032] By adopting the above technical solution, this application has the following beneficial effects:

[0033] (1) The steel casing effectively blocks surface water and other debris from entering the pile hole, avoiding interference during construction and ensuring construction quality and safety. At the same time, the platform body and its supporting blocks, beams and other structures provide stable support for the hoisting and erection of the steel cage, simplifying the construction process and improving construction efficiency.

[0034] (2) The platform body adopts a combination design of an external support frame and an internal support frame, which is connected by welding or integrated molding, significantly enhancing the overall strength and stability of the platform, effectively preventing construction deviations caused by deformation, and ensuring construction accuracy.

[0035] (3) The support blocks are connected to the platform body through side slots, which are not only easy to install but can also be easily removed as needed, making it easier to adjust and reuse the platform. In addition, the lifting lug design on the diagonal corners of the platform body allows the entire platform to be quickly lifted to the construction location using lifting equipment, further improving construction efficiency.

[0036] (4) The concave-convex structure between the side slot and the support block, as well as the setting of the limit clamp and limit plate, effectively limit the horizontal displacement of the support block and avoid construction deviation. At the same time, the special design of the clamp also ensures the stability of the carrying bar in the horizontal direction, further ensuring the installation accuracy of the steel cage.

[0037] (5) The device supports the installation and connection of multiple steel cages in the axial direction, meeting the needs of complex pile foundation construction. At the same time, the design of the hanging bars and rings on the top steel cage, as well as the opening of the hanging slot on the pole, enable the steel cage to be stably suspended under the pole and in the middle of the pile hole, avoiding deviation of the steel cage position during concrete pouring.

[0038] (6) This technical solution has high flexibility and scalability and can be customized and adjusted according to specific construction requirements, such as adjusting the height of the steel casing, the size and shape of the platform body, etc., to adapt to pile foundation construction of different scales and types.

[0060] The present application will be further explained below in conjunction with specific implementation methods.

[0061] Example 1

[0062] like Figure 3-4As shown, this embodiment provides a pouring platform device for pile foundation, including a steel casing 1, a platform body 2, a steel cage 3, a carrying bar 4 and a support block 5;

[0063] The steel casing 1 is a cylindrical outer cylinder with upper and lower openings;

[0064] The steel casing 1 is arranged in the pile hole 6 to prevent surface water or other debris from entering the steel casing 1 and affecting the construction;

[0065] The height of the steel casing 1 exceeds the ground;

[0066] The platform body 2 is arranged on the ground and is located above the pile hole 6;

[0067] The platform body 2 is provided with a side slot 7 for setting the support block 5;

[0068] The support block 5 is inserted into or removed from the side slot 7 from the side of the platform body 2;

[0069] The upper end of the support block 5 is higher than the upper surface of the platform body 2;

[0070] The upper end surface of the support block 5 is provided with a slot 8 that matches the size and shape of the carrying pole 4;

[0071] The steel cage 3 is placed in the pile hole 6 by hoisting;

[0072] When the steel cage 3 is hoisted to a predetermined height, the steel cage 3 is erected on the carrying bar 4 by inserting the carrying bar 4;

[0073] The carrying bar 4 is arranged in the slot 8 of the supporting block 5 .

[0074] As a further embodiment of the present application, the steel cage 3 in the steel casing 1 is provided with a plurality of;

[0075] The plurality of steel cages 3 are arranged and connected in the axial direction.

[0076] like Figure 4-5 As shown, as a further embodiment of the present application, a hanger bar 16 is provided at the upper end of the uppermost reinforcement cage 3;

[0077] The lower end of the suspension rod 16 is connected to the top of the reinforcement cage 3, and the other end is bent into a suspension ring 17;

[0078] Before pouring concrete, the carrying bar 4 passes through the lifting ring 17 so that the steel cage 3 is suspended under the carrying bar 4.

[0079] As a further embodiment of the present application, a hanging groove (not shown in the figure) is opened at the position of the carrying bar 4 corresponding to the hanging ring 17, so that the steel cage 3 is located in the middle position of the pile hole 6 when it is hung under the carrying bar 4, and the position of the steel cage 3 is prevented from deviating when pouring concrete.

[0080] like Figure 1-5 As shown, during actual construction of the grouting platform device for pile foundations disclosed in this application, a pile hole 6 is first excavated and the steel guard plate is inserted into the pile hole 6. The platform body 2 is placed on the steel guard plate, and the support block 5 is inserted through the side slot 7. The support block 5 can be a wooden block or a metal block. The rebar cage 3 is hoisted into the pile hole 6. When the rebar cage 3 reaches a predetermined height, the support bar 4 is inserted through the gap between the rebar cage 3. The support bar 4 is pressed onto the support block 5 and engages with the slot 8 provided on the support block 5. The next rebar cage 3 is then hoisted, with the lower end of the next rebar cage 3 aligned with and connected to the upper end of the previous rebar cage 3. After the two rebar cages 3 are connected, the support bar 4 is removed, and the hoisted and connected rebar cage 3 is lowered again, and the above steps are repeated. When the last rebar cage 3 is hoisted, a lifting rod 16 and a lifting ring 17 are pre-installed on the last rebar cage 3 based on the height of the rebar cage 3 and the height of the support bar 4. After the lifting ring 17 is engaged with the lifting groove provided on the carrying bar 4, the slurry in the pile hole 6 is extracted and concrete is poured. After the concrete solidifies, the support block 5 and the carrying bar 4 are removed and the platform body 2 is lifted and moved. All the above components are reusable.

[0081] By adopting the above technical solution, this application has the following beneficial effects:

[0082] (1) The pile foundation pouring platform device disclosed in this application makes the hoisting and connection process of the steel cage 3 more efficient. The coordinated use of the supporting bar 4 and the support block 5 enables the steel cage 3 to be conveniently erected at a predetermined height without the need for additional manpower or equipment to stabilize the steel cage 3, thereby speeding up the construction progress.

[0083] (2) The hanging groove on the shoulder bar 4 cooperates with the hanging ring 17 on the steel cage 3, ensuring that the steel cage 3 can be kept in the middle position of the pile hole 6 when pouring concrete, effectively avoiding the deviation of the position of the steel cage 3 and improving the construction accuracy.

[0084] (3) The setting of the steel casing 1 effectively prevents surface water and other debris from entering the pile hole 6, avoiding safety hazards during construction. At the same time, the overall structural design of the pouring platform device is stable and can withstand the weight and pressure of the steel cage 3 and concrete pouring, ensuring construction safety.

[0085] (4) All parts of the pouring platform device are reusable, which reduces material waste, construction costs, and waste generation at the construction site, meeting environmental protection requirements.

[0086] (5) The support block 5 can be easily inserted and removed through the side slot 7, and the carrying bar 4 can also be easily installed and disassembled, making the operation process of the entire device simple and quick, reducing the construction difficulty and the labor intensity of workers.

[0087] Example 2

[0088] like Figure 9-14 As shown, this embodiment provides the specific structure and connection method of the side slot 7, support block 5 and carrying bar 4 in Example 1.

[0089] As a further embodiment of the present application, the side wall of the side slot 7 is a concave-convex structure 12, and the side wall of the support block 5 is a concave-convex structure 12 matching the structure of the side slot 7, which is used to limit the position of the support block 5.

[0090] As a further embodiment of the present application, a limiting protrusion 13 is provided at one end of the side slot 7 close to the steel casing 1, and a limiting slot 14 is provided at the other end, and a limiting plate 15 is provided in the limiting slot 14;

[0091] By providing the limiting protrusion 13 and the limiting plate 15 , the position of the support block 5 in the horizontal direction is limited, thereby avoiding deviation in construction caused by displacement of the support block 5 during construction.

[0092] As a further embodiment of the present application, the card slot 8 is a slot body with a large opening at the upper end and a small opening at the lower end, and the side wall of the slot body is a straight wall plane;

[0093] The shapes of the lower parts from both ends of the carrying bar 4 to the joints with the trough body are consistent with the shape of the trough body. The other positions of the carrying bar 4 are rectangular, which is used to displace the carrying bar 4 in the horizontal direction relative to the support block 5, resulting in deviations in construction.

[0094] The support block 5 described in this application is inserted from the side slot 7, and the concave-convex structure 12 on the support block 5 is matched with the concave-convex structure 12 on the side slot 7, and the inner side of the support block 5 abuts against the limiting protrusion 13. Preferably, the height of the limiting protrusion 13 is lower than the height of the support block 5, so that when viewed from the inner side of the platform body 2 to the outside, the support block 5 has a protruding structure, which makes it convenient to knock out the support block 5 later and also leaves space for the carrying bar 4 to fall. After the inner side of the support block 5 completes the abutment, a limiting plate 15 is inserted into the limiting slot 14 on the other side to limit the support block 5. As a result, the support block 5 is limited in all directions to prevent deviations in construction caused by shaking. At this time, the carrying bar 4 is placed on the support block 5. Since the cross-section of the carrying bar 4 near the middle position is a rectangular structure, its protruding part compared to the trapezoidal structure can provide limiting and positioning functions. When it is necessary to remove the carrying bar 4 and the support block 5, the limiting plate 15 is first removed from the limiting slot 14, and then the support block 5 is knocked out from the inner side of the platform body 2. Since the lower shapes of the two ends of the carrying bar 4 also match the shapes of the clamping slot 8, the support blocks 5 can move smoothly along the axis of the carrying bar 4 when knocked out. After the support blocks 5 on both sides are knocked out, the carrying bar 4 falls down due to the loss of support, so that the lifting ring 17 in Example 1 is disengaged from the lifting slot, so that the carrying bar 4 can be pulled out from the side.

[0095] By adopting the above technical solution, this application has the following beneficial effects:

[0096] (1) By matching the side slots 7 with the concave-convex structure 12 on the side wall of the support block 5, the horizontal displacement of the support block 5 is effectively limited, thereby enhancing the structural stability of the entire pouring platform device. This design avoids construction deviations caused by shaking or displacement of the support block 5 during construction, thereby improving construction accuracy.

[0097] (2) The arrangement of the limiting protrusion 13 and the limiting plate 15 enables the support block 5 to be quickly and firmly positioned after being inserted into the side slot 7 without the need for additional fixing measures, which not only simplifies the construction steps but also improves the construction efficiency.

[0098] (3) The design of the support block 5 takes into account the need for easy installation and disassembly. The height of the limit clamp 13 is lower than that of the support block 5, so that the support block 5 has a protruding structure on the platform body 2, which is convenient for knocking out the support block 5 later. At the same time, the design of the carrying bar 4 also takes into account the compatibility with the clamping slot 8, so that when dismantling, it can move smoothly along the axis direction of the carrying bar 4, thereby easily pulling out the carrying bar 4.

[0099] (4) The stable connection between the support block 5 and the carrying bar 4 avoids safety hazards caused by shaking or displacement, provides a safer working environment for construction workers, and ensures the safety of the grouting platform device during the construction process.

[0100] Example 3

[0101] like Figure 6-8 As shown, this embodiment provides the specific structure and selected materials of the platform body 2. The platform body 2 includes an outer support frame 9 and an inner support frame 10;

[0102] The outer support frame 9 is a quadrilateral structure;

[0103] The inner support frame 10 is provided on two adjacent frames of the outer support frame 9 to increase the overall strength of the platform body 2 and prevent construction deviation caused by deformation.

[0104] As a further embodiment of the present application, the outer support frame 9 and the inner support frame 10 are connected by welding or integrally formed.

[0105] As a further embodiment of the present application, lifting ears 11 are provided on the diagonals of the platform body 2 for lifting the platform body 2 to the construction location by means of lifting equipment.

[0106] In this application, the platform body 2 can be a steel or other metal structure. Furthermore, this embodiment also discloses implementations in which the platform body 2 is made of other materials. In this embodiment, the platform body 2 can also be made of polypropylene, which has high strength and compressive strength. It is a green and environmentally friendly material. The dimensions of the platform body 2 are the same as those of the steel structure embodiment. The entire platform body 2 is manufactured in a single factory process, reducing smoke pollution generated by welding. Compared to platform bodies 2 made of steel, the platform body 2 is lightweight and strong. It can be easily transported and used manually, making it easy to operate and reusable. In this embodiment, the platform body 2 can also be made of polyvinyl chloride with internal reinforcement. This relatively inexpensive material improves the device's compressive strength. The entire platform body 2 is manufactured in a single factory process, resulting in high overall stability, reducing smoke pollution generated by welding, and contributing to environmental protection. If the device is damaged, it can be recycled for secondary processing, reducing device costs and making it reusable. Compared to platform bodies 2 made of steel, the platform body 2 is lightweight and strong.

[0107] By adopting the above technical solution, this application has the following beneficial effects:

[0108] (1) By designing a structure combining the outer support frame 9 and the inner support frame 10, the overall strength of the platform body 2 is significantly enhanced. This design effectively prevents the platform body 2 from being deformed due to uneven force during construction, thereby avoiding construction deviations and improving construction accuracy and safety.

[0109] (2) The outer support frame 9 and the inner support frame 10 are connected by welding or integrated molding, which reduces gaps and potential weaknesses at the connection and improves the overall stability and durability of the platform. At the same time, this manufacturing process also simplifies the installation process and reduces the difficulty of construction.

[0110] (3) The lifting lugs 11 provided on the diagonal corners of the platform body 2 allow the platform body 2 to be easily hoisted to the construction site using lifting equipment, greatly improving construction efficiency. In addition, the platform body 2 is made of lightweight materials such as polypropylene or polyvinyl chloride, which can be easily moved and used manually, further simplifying the operation process.

[0111] (4) The use of green and environmentally friendly materials such as polypropylene or polyvinyl chloride to make the platform body 2 not only reduces environmental problems such as smoke pollution, but also conforms to the concept of sustainable development. These materials can be recycled and processed again, reducing resource waste and environmental pollution.

[0112] (5) Compared with the traditional steel structure platform body 2, the platform body 2 made of materials such as polypropylene or polyvinyl chloride has a greater cost advantage. These materials are relatively cheap, and the production process reduces welding and other operations, thereby reducing production costs. At the same time, because the platform body 2 made of these materials is light and strong, it can be reused, further reducing long-term construction costs.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
