Description

Technical Field

[0001] This utility model relates to the field of building construction formwork technology, and in particular to a reusable and quickly assembled steel structure tower crane foundation formwork. Background Technology

[0002] In the construction industry, the construction quality and efficiency of tower crane foundations have a crucial impact on the progress of the entire project. Formwork, as a core component of tower crane foundation construction, directly affects the construction process and cost control. Traditional tower crane foundation formwork has many significant drawbacks:

[0003] In terms of reusability, most traditional formwork is for single use only and cannot be reused. This not only significantly increases construction costs but also causes a large amount of material waste, which contradicts the green construction and environmental protection concepts advocated by the current construction industry.

[0004] In terms of splicing operations, traditional formwork splicing methods are complex and cumbersome, often requiring a large amount of welding or tedious bolt connections, consuming a lot of manpower and time, severely restricting the construction progress, and making it difficult to meet the needs of modern building construction for efficient operations; the support structure design is unreasonable, the installation and disassembly of the support components of traditional formwork are extremely inconvenient, and the support stability is insufficient, which can easily lead to problems such as formwork deformation during construction, affecting the construction quality of the tower crane foundation, and may even bring safety hazards.

[0005] In addition, traditional formwork has poor versatility. Different formwork is often required for tower crane foundations of different shapes (such as rectangular, irregular, etc.), which increases the complexity and cost of construction. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems by providing a reusable and quickly assembled steel structure tower crane foundation template.

[0007] The technical solution of this utility model is implemented as follows:

[0008] This utility model provides a reusable and quickly assembled steel structure tower crane foundation template, the foundation template comprising:

[0009] The template body includes an inner side and an outer side. The template bodies can be welded together along their length direction, or they can be fixed in a first or second placement state.

[0010] The first placement state is that the inner sides of the template bodies are placed at right angles, and the second placement state is that the outer sides of the template bodies are placed at right angles, so that the template bodies can be connected end to end to form a rectangular mold cavity, which is used for pouring foundation.

[0011] The basic template also includes:

[0012] An inner support rod, both ends of which are installed on the inner side of the template body;

[0013] The main steel square tube keel is installed horizontally on the outside of the template body to connect the template body in the first placement state.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following:

[0015] 1. High reusability and cost savings: The formwork is made of metal and can be reused, effectively avoiding the material waste caused by the single use of traditional formwork, significantly reducing construction costs and conforming to the concept of green construction.

[0016] 2. Fast and efficient splicing, improving construction progress: The splicing method between the template bodies is convenient and efficient. In the initial placement state, they are connected by the interlocking of the main steel square tube keel, without the need for complicated welding or bolt fixing operations, which greatly improves the splicing speed and thus speeds up the construction progress.

[0017] 3. The support structure is reasonable, stable, and easy to assemble and disassemble: The internal support rods are connected to the formwork body through the clamping frame. During installation, they can be snapped into the locking groove from above, and during disassembly, they can be detached from above or easily removed through the hoisting point. This provides stable support for the formwork in the early stages of mold cavity formation, ensuring the molding quality of the mold cavity without affecting subsequent construction processes such as steel reinforcement mesh erection and concrete pouring. Simultaneously, the limiting part at the end of the internal support rod cooperates with the limiting area of ​​the locking groove, preventing the internal support rod from detaching from the front end of the clamping frame, further enhancing the stability of the support.

[0018] 4. High structural strength and excellent reliability: The main steel square tube keel is installed horizontally on the outside of the formwork body, and the secondary steel square tube keel is installed vertically on the outside of the main steel square tube keel. The combination of the two further strengthens the overall structural strength of the formwork, ensuring that the formwork can withstand the pressure brought by concrete pouring and other operations during construction, thus guaranteeing the safety and reliability of construction.

[0019] 5. Wide applicability and strong versatility: The template can be fixed in either the first or second placement state, which can adapt to the construction needs of different shaped foundations such as rectangular foundations and irregular foundations with multiple right angles. There is no need to customize templates for different shaped foundations, which improves the versatility and efficiency of the template.

[0020] 6. Easy to dismantle and facilitate turnover: After the foundation is poured, for foundations of the same specifications, there is no need to cut the long side of the formwork for welding. Only the fastening position needs to be removed. After being hoisted to a new position by a crane, it can be quickly reassembled, which simplifies the dismantling and reuse process and further improves the turnover efficiency of the formwork.

[0034] Reference Figure 1 and Figure 2 A reusable and rapidly assembled steel structure tower crane foundation formwork, the foundation formwork includes:

[0035] The template body 10 includes inner and outer sides. The template bodies 10 can be welded together along their length, forming the side edges of the concrete foundation formwork. The template bodies 10 can also be fixed in either a first or a second placement configuration. In the first placement configuration, the inner sides of the template bodies 10 are arranged at right angles; in the second placement configuration, the outer sides of the template bodies 10 are arranged at right angles, allowing the template bodies 10 to be connected end-to-end to form a rectangular mold cavity. This rectangular mold cavity is used for pouring the foundation. Figure 1 and Figure 2 As shown, of course, this is only... Figure 1 and Figure 2 The rectangular mold cavity shown only needs to be placed using the first placement state. If the foundation has multiple right-angled sides, then the second placement state is required for fixation, such as... Figure 4 As shown;

[0036] The basic template also includes:

[0037] The inner support rod 20 has both ends installed on the inner side of the template body 10, such as... Figure 1 and Figure 2As shown, the inner support rod 20 is cross-shaped and installed inside the rectangular mold cavity to support it. Furthermore, a retaining frame 13 is installed inside the template body 10 located in the middle of the rectangular surrounding frame. A retaining groove 131 is formed within the retaining frame 13, and both ends of the inner support rod 20 can be inserted into the retaining groove 131. The top of the retaining frame 13 is open, allowing the inner support rod 20 to be inserted into the retaining groove 131 from above, or detached from the retaining frame 13 from above. After the foundation's steel reinforcement mesh is erected and before concrete pouring, the inner support rod 20 can be inserted into the retaining groove 131 from above. Figure 6 The inner support rod 20 shown is lifted and removed from the hoisting point. The function of the inner support rod 20 is to support the template in the early stage of mold cavity formation.

[0038] Furthermore, the end of the inner support rod 20 has a limiting part 21 extending to both sides, and the engaging groove 131 has a limiting area corresponding to the position of the limiting part 21. When the inner support rod 20 is engaged in the engaging groove 131, the cooperation between the limiting part 21 and the limiting area can prevent the inner support rod 20 from detaching from the front end of the frame 13.

[0039] The basic template further includes: steel square tube main keel 11, which is installed horizontally on the outside of the template body 10. It is used to connect the template body 10 in the first placement state to further strengthen the structural strength of the template. It should be noted that in the first placement state, the template body 10 is connected by the interlocking of the steel square tube main keel 11. In the second placement state, it is connected only by welding.

[0040] The basic formwork also includes: secondary steel square tube joists 12, which are vertically installed on the outside of the main steel square tube joists 11.

[0041] The corners of the aforementioned rectangular mold cavity have two installation methods. In the first embodiment, as shown... Figure 1 As shown, the two opposite sides of the rectangular bounding box are the first side, and the other two opposite sides are the second side.

[0042] In the first placement state:

[0043] On the first side, both ends of the main steel square tube keel 11 are bent at 90° toward the height direction of the template body 10, so that a groove 111 is formed between the bent area and the template body 10. The size of the groove 111 is consistent with the cross section of the main steel square tube keel 11. On the second side, both ends of the main steel square tube keel 11 extend axially so that the main steel square tube keel 11 can be inserted into the groove 111.

[0044] In the second embodiment, the two opposite sides of the rectangular enclosure frame are the first side, and the other two opposite sides are the second side. In the first placement state: on the first side, one end of the steel square tube main keel 11 is bent 90° toward the height direction of the template body 10, so that a groove 111 is formed between the bent area and the template body 10. The size of the groove 111 is consistent with the cross-section of the steel square tube main keel 11. The other end of the steel square tube main keel 11 extends axially to be inserted into the groove 111 formed by another template body 10. The bending section of the first side faces the opposite direction to the bending section of the second side, so that each steel square tube main keel 11 can be tightly fastened.

[0045] After the foundation is poured, the formwork is removed and moved to another location where a foundation of the same specifications needs to be poured. The formwork is made of metal and can be reused. It should be noted that since the specifications of multiple foundations are the same, it is not necessary to cut the formwork welded on the long side. Only the interlocking parts need to be removed. The formwork is then hoisted to the corresponding position by a crane and reassembled.

[0046] by Figure 5 Taking the case of a smaller foundation as an example, the installation method applicable to the first embodiment requires moving the template body 10 on the second side in the direction of the black arrow. The other side is operated in the same way. Then the template can be removed and demolded. For a larger foundation, the installation method applicable to the second embodiment is... Figure 2 As shown, the template body 10 on the second side needs to be knocked upward to make it move upward until the steel square tube main keel 11 is disengaged from the limit of the slot 111, and the demolding work can be completed.

[0047] Based on the above structure, in the second placement state, the two template bodies 10 are welded together, and the steel square tube main keels 11 on the two template bodies 10 are also welded together; wherein, the welding surfaces between the template bodies 10 and the welding surfaces between the steel square tube main keels 11 are perpendicular to each other, such as... Figure 4 As shown, through this welding method, when the right template body 10 is subjected to pressure, the steel square tube main keel 11 on the left template body 10 will bear the force, and when the left template body 10 is subjected to pressure, the right template body 10 will bear the force, forming a mutually supporting system to ensure structural stability.

[0048] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
