Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a protective device for aluminum formwork staircases that can be easily installed and dismantled. Background Technology

[0002] With the increasing application of aluminum formwork systems, a quick-disassembly protective method has not yet been developed for the protection of aluminum formwork staircases. Traditional protection methods are time-consuming and labor-intensive, and the protective effect is not ideal, which restricts the efficiency of aluminum formwork systems. Therefore, it is necessary to develop a quick-disassembly protective device for aluminum formwork staircases. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a protective device for aluminum formwork stairs that can be easily installed and disassembled, making it easy to install and disassemble, enabling rapid and flexible turnover, providing reliable protection, having a simple structure, being easy to manufacture, and being inexpensive, thereby overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides a protective device for aluminum formwork stairs that can be easily installed and dismantled, including an angle steel bottom beam, uprights, crossbars and connecting plates;

[0005] The angle steel bottom beam is an angle steel that is inclined at the same angle as the aluminum formwork staircase. Several uprights are set vertically and welded to the angle steel bottom beam at equal intervals. Several horizontal bars are inclined at the same angle as the angle steel bottom beam and welded to the uprights at equal intervals, so that the horizontal bars, uprights and angle steel bottom beam together form a parallelogram grid frame structure.

[0006] The connecting plate is rectangular, and multiple connecting plates are spaced apart along the length of the angle steel bottom beam. Each connecting plate is welded and fixed to the outer side of the vertical surface of the angle steel bottom beam and extends below the angle steel bottom beam. The connecting plate and the side formwork of the aluminum formwork staircase have connection holes at corresponding positions.

[0007] The angle steel bottom beam is placed on the side formwork of the aluminum formwork staircase, and the pin is inserted into the connecting hole of the connecting plate and the side formwork and locked with a pin plate.

[0008] As an improvement of this utility model, the angle steel bottom beam is made of angle steel with a specification of 50mm×50mm×2.

[0009] The uprights and crossbars are made of 25 mm × 25 mm galvanized square tubing.

[0010] The spacing between the uprights is 0.8m, and the spacing between the horizontal bars is 0.6m.

[0011] The connecting plate is made of 100mm×50mm steel plate, the spacing between adjacent connecting plates is 0.9m, and the diameter of the connecting hole is 20mm.

[0012] With this design, the present invention has at least the following advantages.

[0013] 1. This utility model adopts a modular design. Multiple protective devices are connected to the side mold of the aluminum formwork staircase through pins and pin plates, which makes installation and disassembly convenient and enables rapid turnover.

[0014] 2. The protective effect is reliable, protecting both the side formwork itself and the safety of construction workers;

[0015] 3. It has a simple structure, is easy to manufacture, and has a low cost. Attached Figure Description

[0021] Please see Figures 1 to 3 This utility model provides a protective device for aluminum formwork stairs that can be easily installed and dismantled, including an angle steel bottom beam 1, a vertical pole 2, a horizontal pole 3, and a connecting plate 4.

[0022] The angle steel base beam 1 is an inclined angle steel, with the inclination angle matching that of the aluminum formwork staircase 7. Several vertical posts 2 are vertically installed and welded to the angle steel base beam 1 at equal intervals. Several horizontal posts 3 have the same inclination angle as the angle steel base beam 1 and are welded to the vertical posts 1 at equal intervals. The horizontal posts 3, vertical posts 2, and angle steel base beam 1 together form a parallelogram grid frame structure.

[0023] In this embodiment, the angle steel base beam 1 is made of 50mm×50mm×2 angle steel, and the uprights 2 and crossbars 3 are both made of 25mm×25mm galvanized square tubing. The spacing between adjacent uprights 2 is 0.8m, the length of upright 2 is 1.2m, and the crossbars 3 are arranged in two layers, with the upper layer located at the top of the uprights 2 and the lower layer located in the middle of the uprights 2. The spacing between the upper and lower layers of crossbars 3, and the spacing between the lower crossbar 3 and the angle steel base beam 1, are both 0.6m.

[0024] The connecting plate 4 is rectangular, and multiple connecting plates 4 are spaced apart along the length of the angle steel bottom beam 1. The connecting plate 4 is welded and fixed to the outer side of the vertical surface of the angle steel bottom beam 1 and extends below the angle steel bottom beam 1. Connection holes are opened at corresponding positions on the connecting plate 1 and the side formwork 8 of the aluminum formwork staircase 7.

[0025] It should be noted that the opening on the side formwork 8 is located at the inside corner formed by the riser and the tread. Making an opening at this location does not affect the pouring of the aluminum formwork staircase 7, nor does it affect the reuse of the side formwork 8.

[0026] In this embodiment, the connecting plate 4 is made of 100mm×50mm steel plate, the spacing between adjacent connecting plates 4 is 0.9m, and the diameter of the connecting hole is 20mm.

[0027] When using this utility model, the angle steel bottom beam 1 is placed on the side mold 8 of the aluminum formwork staircase 7, and the connecting plate 4 is aligned with the connecting hole on the side mold 8. After inserting the pin 5 into the connecting hole, it is locked with the pin piece 6, which can achieve quick installation and disassembly. According to feedback from on-site operators, the average installation and disassembly time of this utility model is about 10 minutes.

[0028] This utility model is easy to install and disassemble, can be quickly reused, has reliable protective effect, simple and lightweight structure, is easy to manufacture, and has low cost.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
