Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a reusable prefabricated tower crane foundation protection plate. Background Technology

[0002] As an indispensable large-scale lifting equipment in construction, the stability and safety of the tower crane's foundation structure are of paramount importance. Tower crane foundations are typically constructed of poured concrete and exposed to the construction site, making them susceptible to external environmental influences such as rainwater erosion and debris accumulation. Furthermore, the area around the tower crane foundation is frequently frequented by people; without effective protective measures, unauthorized personnel may climb the tower crane, potentially leading to safety accidents.

[0003] Traditional tower crane foundation protection measures are mostly temporary structural modifications, such as using steel pipes to build fences or fixed steel plate welding protection. This method is not reusable. Fixed protection structures are often abandoned after the tower crane is dismantled and cannot be reused, resulting in material waste and increased costs. Moreover, the welding and fixing process requires professional workers, which is time-consuming and inconvenient to dismantle, affecting the construction progress. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1-4 As shown, this utility model provides a reusable prefabricated tower crane foundation protection plate, including an outer protective plate 1, an inner protective plate 2, and a tower crane foundation 7. A tower crane standard section 8 is installed on the upper surface of the tower crane foundation 7. The outer protective plate 1 is installed on the surface of the tower crane foundation 7 and is located outside the tower crane standard section 8. The inner protective plate 2 is installed in the middle of the upper surface of the outer protective plate 1 and is located inside the tower crane standard section 8. Both the outer protective plate 1 and the inner protective plate 2 are assembled from several plates.

[0027] As an optional implementation, the outer protective plate 1 is composed of eight trapezoidal steel plates 101. Each trapezoidal steel plate 101 has a right-angle portion 102 and a hypotenuse portion 103. Two pads 3 are provided below each pair of adjacent right-angle portions 102. Each pad 3 is provided with a bolt connector for adjusting the position between the two trapezoidal steel plates 101. Two L-shaped pads 4 are provided below each pair of adjacent hypotenuse portions 103. Each L-shaped pad 4 is provided with an insertion structure for fixing the position of the two hypotenuse portions 103. By stacking and splicing the eight trapezoidal steel plates 101, the outer protective plate 1 can be adapted to the size of various tower crane standard sections 8. At the same time, the height of the pads 3 and L-shaped pads 4 compensates for the unevenness of the tower crane foundation 7 surface, preventing the protective plate from tilting or shaking after installation. In addition, the pads 3 and L-shaped pads 4 are made of vulcanized rubber, which is elastic and can absorb the vibration or impact load during tower crane operation.

[0028] Reference Figure 3 As shown, two adjacent right-angled portions 102 are stacked on top of each other. The bolt connection includes two bolts 301 fixedly connected to the upper surface of the pad 3. Several positioning holes 302 for inserting into the bolts 301 are opened on the surface of the two adjacent right-angled portions 102. The upper thread of the bolts 301 is connected to the nuts 303 for clamping and fixing the two right-angled portions 102. The outer protective plate 1 is assembled from eight trapezoidal steel plates 101 through the bolt connection and the insertion structure. After the steel plates of the two adjacent right-angled portions 102 are stacked, they are supported by the pad 3. After the bolts 301 pass through the positioning holes 302 on the two steel plates, the nuts 303 are tightened to achieve horizontal fixation. At this time, the inner ring of the outer protective plate 1 is adapted to the outer size of the tower crane standard section 8.

[0029] As an optional implementation, the plug-in structure includes a U-shaped pin 402. The upper surface of the L-shaped pad 4 is provided with a pin hole 401 that is adapted to the U-shaped pin 402. Each of the two adjacent inclined sides 103 is provided with a fixing hole 403 for inserting the U-shaped pin 402. A magnet 404 is fixedly connected to the inner bottom of the pin hole 401. The magnet 404 is magnetically connected to the iron U-shaped pin 402. The connection between the two adjacent inclined sides 103 is achieved by simultaneously inserting the U-shaped pin 402 into the two fixing holes 403 and the two pin holes 401 on the L-shaped pad 4. The magnet 404 assists in fixing the U-shaped pin 402, ensuring a tight connection between the two inclined sides 103.

[0030] Reference Figure 4 As shown, the inner ring guard plate 2 is formed by stacking four L-shaped steel plates 201. The outer corners of the four L-shaped steel plates 201 are provided with notches 202 that are adapted to the uprights of the tower crane standard section 8. There are bolt connectors 25 between each pair of adjacent L-shaped steel plates 201 to fix the distance between them. The middle of the four L-shaped steel plates 201 is provided with a bending line, and the four L-shaped steel plates 201 are stacked to form a truncated pyramid shape. The slope height of the L-shaped steel plates 201 is 3-5cm. The inner ring guard plate 2 is stacked on top of the outer ring guard plate 1. The surfaces of the inner ring guard plate 2 and the outer ring guard plate 1 are provided with a warning anti-corrosion coating. The notches 202 are adapted to the uprights of the tower crane standard section 8 to form an inner closed protection. The outer ring guard plate 1 covers the perimeter of the tower crane foundation 7 to prevent personnel from climbing or falling objects from impacting it. After the inner ring guard plate 2 is stacked, it forms a sloping structure (sloping height 3-5cm), which further prevents personnel from approaching the uprights of the tower crane standard section 8 and avoids water accumulation.

[0031] As an optional implementation, the bolted connector 25 includes a bolt 201, which is fixedly connected to the surface of the lower L-shaped steel plate 201. The surface of the upper L-shaped steel plate 201 has several positioning holes 202 for inserting the bolt 201. The bolt 201 is threaded with a nut 203 for pressing and stacking the L-shaped steel plates 201. The inner ring guard plate 2 is formed by stacking four L-shaped steel plates 201 into a truncated pyramid shape. By inserting the bolt 201 into the positioning hole 202 in a suitable position and rotating the nut 203 to fix it, the notch 202 is adapted to the tower crane standard section 8 upright, forming an inner closed protection.

[0032] Furthermore, each of the two stacked L-shaped steel plates 201 has a through hole 6 that is compatible with the bolt 301. The through hole 6 facilitates the fixing of the inner ring guard plate 2 to the surface of the outer guard plate 1. The through hole 6 can be drilled at the edge of the L-shaped steel plate 201 by a drilling machine after the positions of the inner ring guard plate 2 and the outer guard plate 1 have been determined.

[0033] Specifically, both pad 3 and L-shaped pad 4 are made of vulcanized rubber and are fixed to the surface of the tower crane foundation 7 by expansion bolts. The height of pad 3 and L-shaped pad 4 compensates for the unevenness of the surface of the tower crane foundation 7, preventing the protective plate from tilting or shaking after installation. At the same time, the vulcanized rubber material of pad 3 and L-shaped pad 4 is elastic and can absorb the vibration or impact load during tower crane operation, reduce the wear and noise of the protective plate, prevent the steel plate from hard collision with the tower crane foundation 7, and extend the service life of the protective plate.

[0034] The outer protective plate 1 is assembled from eight trapezoidal steel plates 101 using bolted connectors and a plug-in structure. Adjacent right-angled steel plates 102 are supported by pads 3. Bolts 301 pass through positioning holes 302 on the two steel plates and are tightened with nuts 303 to achieve horizontal fixation. The connection between adjacent inclined plates 103 is achieved by inserting U-shaped pins 402 into two pin holes 401 on L-shaped pads 4. Magnets 404 assist in fixing the U-shaped pins 402, ensuring a tight fit between the inclined plates. The inner ring guard plate 2 is made of four L-shaped steel plates 201 stacked into a truncated pyramid shape. It is fixed by inserting bolts 2 501 into the positioning holes 2 502 in the appropriate positions and rotating nuts 2 503. The notch groove 202 is adapted to the tower crane standard section 8 uprights to form an inner closed protection. The outer guard plate 1 covers the perimeter of the tower crane foundation 7 to prevent personnel from climbing or falling objects from impacting it. After the inner ring guard plates 2 are stacked, they form a sloping structure (sloping height 3-5cm), which further prevents personnel from approaching the tower crane standard section 8 uprights and at the same time avoids water accumulation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
