[0004] However, this device has the following shortcomings:

[0005] 1. When the treadmill is used in building construction, its strength performance is very important. Although the treadmill mentioned above can be folded, the strength of its folded part is relatively weak when the treadmill is unfolded and used, which makes it easy to deform when using it, thereby increasing the danger of using the treadmill.

[0006] 2. Due to the existence of certain dimensional errors during scaffolding erection, and the different dimensions of scaffolding erected in different locations, the aforementioned treads cannot adjust the hook length according to the scaffolding dimensions, resulting in a limited range of applicability for the device. Utility Model Content

[0007] The purpose of this invention is to provide a foldable temporary stair tread structure for building construction, in order to solve the existing problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a foldable temporary step board structure for building construction, including a step A, a step B hinged to one side of the step A, two sets of hook assemblies provided on the other side of the step A, and a reinforcing assembly provided at the bottom of the step A;

[0012] Preferably, a hidden hole is provided on the top inner side of the storage groove away from the movable rod to accommodate the bolt, thereby concealing the bolt.

[0013] Preferably, the tops of pedals A and B are uniformly provided with anti-slip protrusions, which can improve the anti-slip performance of pedals A and B and increase the stability of stepping.

[0014] Preferably, the two sets of hooks on the same side are provided with a pull rod at one end, which makes it convenient to adjust the length of the two sets of hooks on the left side by pulling the pull rod. At the same time, after pedal A and pedal B are folded, the device can be moved by pulling the pull rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the structure of this foldable temporary construction step board:

[0016] 1. Through the cooperation between the storage slot, movable rod, spring B, support plate, threaded hole and bolt, after the pedal is unfolded, the support plate flips and snaps into the bottom of the connection between pedal A and pedal B, which can directly form rigid support for the folded part. This not only avoids the connection from deforming due to force and affecting construction safety, but also further strengthens the overall structural strength of the step plate, making the pedal more stable and reliable during the load-bearing process.

[0017] 2. Through the cooperation between the guide hole, guide rod, spring A and hook, the device can achieve adaptive extension and retraction adjustment by means of the elastic movement of the hook. It can accurately match the installation requirements of scaffolding with different spacing specifications without the need for additional adapter parts or complicated adjustment operations. This effectively broadens the applicable scenarios and adaptation range of the device and significantly improves its versatility and practicality in diverse construction scenarios.
