Description

Technical Field

[0001] This utility model relates to the field of prefabricated staircase protection technology, and in particular to a temporary protection device for prefabricated staircases. Background Technology

[0002] With the increasing maturity of prefabricated construction technology, the use of prefabricated construction projects is becoming more and more common, and prefabricated stairs are an important component of this. After the prefabricated stairs are constructed, they need to be protected in a timely manner for the purpose of protecting the finished product. A common method is to use plastic to lay the platform, but plastic cannot adhere firmly to the plane of the stair steps, which can easily lead to unevenness. After long-term use, the steps are prone to shifting and need to be re-laid. Moreover, plastic usually cannot protect the sides, making it susceptible to construction contamination. On the other hand, if formwork is used for protection, it is prone to corrosion and warping after prolonged use due to moisture or exposure to sunlight, resulting in a decrease in the safety factor for personnel passage.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a temporary protection device for prefabricated stairs. The temporary protection device for prefabricated stairs includes a prefabricated stairs 100, which includes a horizontal surface 101, a vertical surface 102, a side surface 103, and a bottom surface 104.

[0029] The protective component 200 is installed on the prefabricated staircase 100 and includes a protective element 201. The protective element 201 includes a horizontal panel 201a, a vertical panel 201b, and a side panel 201c. The horizontal panel 201a is located on the horizontal surface 101, the vertical surface 102 is installed on the vertical surface 102, and the side panel 201c is located on one side of the side surface 103.

[0030] The protective component 201 is used to protect the horizontal surface 101, the vertical surface 102, and the side surface 103, protecting the prefabricated staircase 100 from wear and damage. In addition, it can reduce the pollution of the prefabricated staircase 100 during other construction processes.

[0031] During installation, pay attention to the corresponding overlap between the face and panel. Horizontal panel 201a corresponds to horizontal face 101, vertical panel 201b corresponds to vertical face 102, and side panel 201c corresponds to side face 103.

[0032] The protective component 200 also includes an auxiliary component 202, which is disposed on one side of the side panel 201c. It includes a baffle 202a, a fixing block 202b, and a first torsion spring 202c. The baffle 202a is disposed on one side of the side panel 201c, the fixing block 202b is fixed on the side panel 201c, and the two ends of the first torsion spring 202c are respectively fixed to the baffle 202a and the fixing block 202b. The baffle 202a and the fixing block 202b are rotatably connected, and the baffle 202a can fit against the bottom surface 104.

[0033] By setting the auxiliary component 202, the side panel 201c is limited, and the horizontal panel 201a and vertical panel 201b are also limited, ensuring that the entire protective component 200 will not shift its position due to frequent personnel passage, thereby improving the safety factor of personnel entering and exiting.

[0034] As shown in the figure, under the action of the first torsion spring 202c, the baffle 202a will always rotate towards the bottom surface 104, so as to fit tightly against the bottom surface 104.

[0035] When installing the protective component 200, the baffle 202a needs to be manually rotated in the opposite direction to compress the first torsion spring 202c, ensuring that the side panel 201c can smoothly fit against the side 103. After the two are fully fitted, the baffle 202a is released, and the first torsion spring 202c returns to its original position, causing the baffle 202a to rotate to a position where it fits against the bottom surface 104, and presses against the bottom surface 104 to ensure that the bottom surface 104 and the baffle 202a fit tightly together. This prevents the horizontal panel 201a, the vertical panel 201b, and the side panel 201c from shifting, which could affect the safety of the construction personnel.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the horizontal panel 201a, vertical panel 201b, and side panel 201c are all made of printed sheet metal.

[0039] The printed sheet metal is wear-resistant, slip-resistant, and reusable, thereby increasing the service life of the horizontal panel 201a, vertical panel 201b, and side panel 201c.

[0040] Specifically, bolts 201e are fixed on the horizontal panel 201a.

[0041] Bolt 201e is fixed to horizontal panel 201a by welding.

[0042] Specifically, four bolts 201e form a group, and two groups of bolts 201e are on a horizontal panel 201a.

[0043] Bolt 201e is used for later installation and fixing of the edge protection post. The bottom of the post has a mounting hole corresponding to bolt 201e. During installation, adjust the protection post so that bolt 201e is inserted into the mounting hole at the bottom of the post. Then use nuts and washers. When tightening the nuts, tighten them diagonally to ensure that the protection post is installed firmly and vertically.

[0044] By using pre-set bolts 201e, construction time is saved, and protective columns can be installed without damaging the prefabricated stairs.

[0045] Specifically, the horizontal panel 201a and the vertical panel 201b are fixed together, and the horizontal panel 201a and the vertical panel 201b are at right angles.

[0046] Specifically, the side panel 201c is hinged to one end of the horizontal panel 201a.

[0047] The side panel 201c and the horizontal panel 201a are hinged together by the hinge 201f, which allows for folding and flexible construction. Prefabricated stairs of the same size can be reused, thereby saving construction costs.

[0048] Example 3

[0049] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, the auxiliary component 202 also includes a limiting block 202d and a fixing plate 202e. The limiting block 202d is disposed on one side of the side panel 201c, and the fixing plate 202e is fixed on the vertical panel 201b. The limiting block 202d and the fixing plate 202e are rotatably connected.

[0051] The limiting block 202d and the fixing plate 202e are set to ensure that the side panel 201c fits tightly against the side 103.

[0052] Specifically, a second torsion spring 202f is fixed to one side of the limiting block 202d, and the other end of the second torsion spring 202f is fixed to the fixing plate 202e.

[0053] As shown in the figure, under the action of the second torsion spring 202f, the limiting block 202d is pushed to rotate towards the side 103, thereby squeezing the side 103 and making the side panel 201c fit tightly against the side 103.

[0054] During installation, the limiting block 202d needs to be manually rotated to further compress the second torsion spring 202f, ensuring that the limiting block 202d does not obstruct the side panel 201c from approaching the side 103. After ensuring that the two are in contact, the limiting block 202d is released, and the second torsion spring 202f will push the limiting block 202d to rotate toward the side 103 again, so that the side panel 201c is in close contact with the side 103, preventing the side panel 201c from shifting position.

[0055] Specifically, anti-slip strips 201d are fixed on the horizontal panel 201a.

[0056] Two anti-slip strips 201d are provided on a horizontal panel 201a to improve the safety of personnel entering and exiting.

[0057] The protection component 200 is reusable.

[0058] The prefabricated staircase 100 protected by this solution has one side 103 in contact with the wall. There are multiple protective components 200. The appropriate number is selected according to the number of steps of the prefabricated staircase 100 to ensure that all sides of the prefabricated staircase 100 except the bottom surface 104 have corresponding panels for protection. This protects the prefabricated staircase from wear or damage. In addition, it can reduce the pollution of the prefabricated staircase during other construction processes.

[0059] When using, ensure that the surfaces and panels correspond and overlap. Horizontal panel 201a corresponds to horizontal surface 101, vertical panel 201b corresponds to vertical surface 102, and side panel 201c corresponds to side surface 103. Manually rotate baffle 202a in the opposite direction to compress the first torsion spring 202c, ensuring that side panel 201c can smoothly adhere to side surface 103. Once they are fully adhered, release baffle 202a. The first torsion spring 202c will return to its original position, causing baffle 202a to rotate to a position where it adheres to bottom surface 104, and then align with the bottom... The bottom surface 104 is pressed to ensure that the bottom surface 104 is in close contact with the baffle 202a. At the same time, the limiting block 202d is manually rotated to further compress the second torsion spring 202f, ensuring that the limiting block 202d does not obstruct the side panel 201c from approaching the side 103. After ensuring that the two are in close contact, the limiting block 202d is released. The second torsion spring 202f will push the limiting block 202d to rotate towards the side 103 again, so that the side panel 201c is in close contact with the side 103, preventing the side panel 201c from shifting position.

[0060] When installing the edge protection post, adjust the post so that the bolt 201e is inserted into the mounting hole at the bottom of the post. Then, use nuts and washers to tighten the nuts diagonally to ensure that the protection post is installed firmly and vertically.

[0061] When disassembly is required, first remove the protective column, then rotate the baffle 202a and the limiting block 202d in the opposite direction to remove the horizontal panel 201a, vertical panel 201b and side panel 201c from the prefabricated staircase 100 and store them in an orderly manner. This facilitates the reuse of prefabricated staircases 100 of the same size, thereby saving construction costs.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
