Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure support technology, and in particular to a steel structure support column for building formwork. Background Technology
[0002] Construction formwork is a temporary support structure, made according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and the external loads acting on it. The traditional construction method is to directly erect scaffolding and then install wooden formwork. This method has a large workload and limited application scope. In addition, it cannot be easily raised or lowered and lengthened as needed, which ultimately greatly affects the operation of the construction process.
[0003] When applying for this invention, the applicant searched and found a Chinese patent that discloses a "steel structure support column for building formwork" with application number "202410972820.0". This patent mainly utilizes the axial movement capability of the threaded structure under force to provide effective height support for building formwork, and the support height is adjustable. Although the patent description mentions that it can provide effective height support for building formwork and that the support height is adjustable, the lifting and lowering process is not stable enough when adjusting the support height of the building formwork, and the base of the device cannot provide a stable support effect on uneven ground. Utility Model Content
[0004] The purpose of this utility model is to provide a steel structure support column for building formwork, which solves the problems that the lifting and lowering process of the steel structure support column is not stable when adjusting the support height of building formwork, and that the base cannot provide stable support for the device on uneven ground.
[0005] To achieve the above objectives, a steel structure support column for building formwork is provided, comprising: a motor, a threaded rod fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the threaded rod, a sliding rod fixedly connected to the threaded sleeve, a limit block fixedly connected to the bottom of the threaded sleeve, and a flange base fixedly connected to the bottom of the motor.
[0006] According to the steel structure support column of the building template, a fixing sleeve is fixedly connected to the upper surface of the flange base.
[0007] According to the steel structure support column of the building template, the top surface of the fixing sleeve is provided with a sliding groove.
[0008] According to the steel structure support column of the building formwork, a support steel plate is fixedly connected to the top surface of the threaded sleeve.
[0009] The above-mentioned solution has the following beneficial effects:
[0010] 1. This patent, by setting a fixed sleeve, can significantly improve the stability of the threaded sleeve during the lifting process and achieve the effect of limiting the threaded sleeve.
[0011] 2. This patent also improves the safety factor and installation efficiency by fixing a flange base at the bottom of the device, which allows the device to handle a relatively large number of construction sites and makes it easy to fix the device stably on the construction site.
[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Reference Figure 1-4This utility model discloses a steel structure support column for building formwork, comprising: a motor 1, a threaded rod 2 fixedly connected to the output end of the motor 1, a threaded sleeve 3 threadedly connected to the threaded rod 2, a sliding rod 4 fixedly connected to the threaded sleeve 3, a limit block 5 fixedly connected to the bottom of the threaded sleeve 3, and a flange base 9 fixedly connected to the bottom of the motor 1. By fixing the flange base 9 to the bottom of the device, the device can handle a relatively large number of construction ground surfaces and facilitates stable fixing of the device to the construction ground surface, significantly improving the safety factor and installation efficiency. The flange base 9 has the following additional beneficial effects: In the steel structure support system of building formwork, the flange base 9 is a key component connecting the support column to the ground or lower structure. The concrete pouring load (usually 10-50 tons) borne by the support column is transferred to the foundation through the flange base 9, increasing the contact area and avoiding excessive local pressure that could lead to foundation settlement or damage. If the diameter of the support column steel pipe is Φ60mm, the direct ground pressure is extremely high; The flange base 9 (such as a 200mm×200mm steel plate) can reduce the pressure to less than 1 / 10. The flange base 9 is fixed by bolt anchoring or welding to prevent the support column from slipping or overturning under horizontal forces (such as wind loads and concrete lateral pressure). The plug-in support column without a base is prone to instability due to small disturbances, while the flange base 9 provides a rigid connection, which significantly improves the resistance to lateral displacement. The flange base 9 is usually used in conjunction with adjustable nuts or wedge-shaped blocks. The verticality of the support column can be corrected by fine-tuning bolts (error ≤ 1 / 500) to ensure the overall flatness of the formwork system. The flange base 9 is fixed to the completed concrete floor slab / foundation by expansion bolts or chemical anchors. It is suitable for high-rise building construction layer by layer. In soft soil foundations or backfilled soil areas, steel plates or sleepers need to be placed under the base to further disperse the pressure and prevent settlement. In prefabricated buildings or steel frames, the base is directly welded to the steel beam or embedded parts to form a rigid support node. Types of flange base 9 include adjustable U-shaped bases and simple plug-in bases.
[0022] A fixed sleeve 6 is fixedly connected to the upper surface of the flange base 9. A groove 7 is formed on the top surface of the fixed sleeve 6. By setting the fixed sleeve 6, the stability of the threaded sleeve 3 during lifting and lowering is significantly improved, and the threaded sleeve 3 is effectively limited. Furthermore, by forming the groove 7 on the upper surface of the fixed sleeve 6, the device achieves the following improvements: The groove 7 is a key functional component in the steel structure support column system, possessing highly precise adjustment capabilities, with a typical adjustment range of 150-400mm. The specially designed corrugated groove wall can absorb 15-20% of the impact load. For high-rise building applications, a double locking device must be installed. The groove wear must be checked after every 50 uses (limited wear ≤1mm). In humid environments, stainless steel (304 / 316 grade) should be used. This design, through a modular sliding mechanism, has been tested to reduce the support system adjustment time by 30% and improve load transfer efficiency by 25%. A specially designed self-lubricating coating (MoS2 composite coating) ensures good operability even at -30℃.
[0023] A support steel plate 8 is fixedly connected to the top surface of the threaded sleeve 3. By setting the support steel plate 8 on the top of the device, the device can be improved in the following ways: The support steel plate 8 is the core load-bearing component of the steel structure support column system, which has the functions of structural stability guarantee and construction adjustment. By optimizing the stress distribution, this component can increase the safety factor of the support system by 40%. The specially designed drainage channel (section 20×10mm) can effectively solve the problem of corrosion caused by water accumulation. Actual tests show that the support steel plate 8 with the reinforced rib design can reduce the amount of material used by 25% while increasing the load-bearing capacity by 30%.
[0024] Working principle: When the motor 1 is started, the threaded rod 2 begins to rotate. Through the principle of threaded connection, the threaded sleeve 3, which is confined in the fixed sleeve 6, will move up and down stably along the slide groove 7. Under the action of the limit block 5, it is prevented from falling off the device, so as to achieve the function of stabilizing and adjusting the height of the building formwork that needs to be supported on the supporting steel plate 8. The bottom of the device is fixedly installed with a flange base 9, which allows the device to cope with a relatively large number of construction grounds and reduces the difficulty of stabilizing the device on the construction ground, significantly improving the safety factor and installation efficiency.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
