[0002] In the field of prefabricated construction ramp technology, this construction ramp mainly solves the problem of transporting materials from outdoors to indoors during indoor construction. For some houses with outdoor steps, difficulties arise when transporting materials. Existing step-to-ramp facilities are usually fixed in size and cannot be adapted to different step sizes. Furthermore, installation, dismantling, and storage are difficult. The practical purpose of this construction ramp is to be laid on steps, turning them into ramps. Material transport trolleys can be pushed into the room through this construction ramp without damaging the steps. Its pull-out extension design can accommodate gaps created after extending steps of different sizes, and can also allow any loose materials to fall to the ground, preventing materials from remaining on the ramp and maintaining constant friction. This quick-release prefabricated construction ramp solves the problems of difficult material transportation, easy damage to steps, and inability to adapt to different step sizes.

[0003] Therefore, how to provide quick-release prefabricated construction ramps that are easy to install and dismantle, convenient to use, easy to lay on stair passages, can protect the steps from damage, and can be adapted to different step sizes is a problem that urgently needs to be solved by those skilled in the art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The quick-release prefabricated construction ramp of this utility model includes a tensioning device 1 and a first connecting device 2 installed below the tensioning device 1. A rotatable ramp plate 3 is installed on the first connecting device 2. A right-angle fixing device 4 is provided on the tensioning device 1. A second connecting device 5 is installed above the tensioning device 1.

[0028] The right-angle fixing device 4 is provided with a rubber buffer layer 41, and a positioning device 44 is provided behind the right-angle fixing device 4.

[0029] The second connecting device 5 is equipped with two spring self-locking devices 51, arranged symmetrically. The second connecting device 5 also includes an upper triangular locking mechanism 52 and a lower triangular locking mechanism 53 below it. The two triangular locking mechanisms are coaxially mounted on the guide post 54. The upper triangular locking mechanism 52 can move up and down along the guide post 54. The rubber buffer layer 41 can buffer the impact generated during construction by the material transport trolley. The positioning device 44 behind it can fix the right-angle fixing device 4 in the required position. When the second tensioning structure 12 needs to be stretched to its maximum length, the upper triangular locking mechanism 52 will first push open the spring self-locking devices 51 on both sides. The spring self-locking device 51 is locked between the upper and lower triangular locking mechanisms. Since the limiting clip 511 on the spring self-locking device 51 is a triangular structure with its hypotenuse on top and one right-angled side on the bottom, the second stretching structure 12 cannot retract, thus achieving the effect of "stretching-self-locking-unretracting". When the second stretching structure 12 needs to be retracted, it can be stretched outwards. Then the upper triangular locking mechanism 52 will push open the spring self-locking device 51. Due to its gravity, the upper and lower triangular locking mechanisms will merge together, and the spring self-locking device 51 cannot lock between the upper and lower triangular locking mechanisms, thus achieving the retraction effect of the second stretching structure 12, i.e., the effect of "stretching-unlocking-retracting".

[0030] The tensioning device 1 is divided into a first tensioning structure 11 and a second tensioning structure 12. The first tensioning structure 11 and the second tensioning structure 12 are installed in a staggered manner. The tensioning device 1 is provided with a track structure 14, and the track structure 14 is provided with limiting holes 13 on both sides.

[0031] The first connecting device 2 is equipped with a first rotary bearing 21, which allows the ramp slab 3 to rotate, so that the ramp slab 3 can be laid on the ground at any angle.

[0032] The rubber buffer layer 41 is provided with anti-slip protrusions 42, and its right-angle structure is connected to the connecting post 43. The connecting post 43 is connected to the positioning device 44, and the positioning device 44 is provided with a limiting plate 45. A second rotary bearing is provided between the right-angle structure and the connecting post 43. The connecting post 43 is located inside the track structure and can slide up and down along the track structure 14. The positioning hole 441 on the positioning device 44 corresponds to the limiting hole 13. When the right-angle fixing device is adjusted to a suitable position, the positioning hole 441 can be aligned with the limiting hole 13, and then the limiting post on the limiting plate 45 can be used for fixing, thereby fixing the right-angle fixing device at a suitable angle. The second rotary bearing adjusts the angle of the right-angle fixing device.

[0033] The positioning device 44 is provided with a positioning hole 441, which is used to align with the limiting hole 13, and then the limiting plate 45 is used to fix it.

[0034] The limiting plate 45 is provided with a limiting post 451, which is used to fix the positioning device 44 and the tensioning device 1.

[0035] The spring self-locking device 51 is provided with a limiting clip 511, which has a triangular structure.

[0036] In use, first, the tension structure 1 is stretched and extended. The spring self-locking device 5 will lock, ensuring that the tension structure 1 will not retract. The right-angle fixing device 4 can slide up and down along the track structure 14. Then, it is adjusted to a suitable position according to the limiting hole 13. The tail end of the right-angle structure on the right-angle fixing device 4 is equipped with a second rotary bearing, which can adaptively adjust the right-angle structure of the right-angle fixing device 4 to a suitable angle. The adjusted right-angle fixing device 4 is fixed by the positioning device 44 on the right-angle fixing device 4 through the positioning hole 441 using the limiting plate 45. The right-angle fixing device 4 is equipped with a rubber buffer layer 41 and anti-slip protrusions 42. The rubber buffer layer 41 can buffer the impact force generated during construction, and the anti-slip protrusions 42 can prevent the construction ramp from slipping, thereby achieving the effect of protecting the steps. The plate 3 is rotatable, allowing the lower ramp plate to be laid flat on the ground and the upper ramp plate to be laid on the upper surface. Then, the tensioning device 1 is placed on the steps, forming a ramp between the two steps for pedestrians and material transport trolleys to pass through. If the length of the construction ramp is insufficient, two or more plates can be overlapped to extend its length. When two construction ramps are overlapped, they do not need to be fixedly connected; simply overlap the ramp plates 3 vertically. The right-angle fixing device 4 will prevent the construction ramp from sliding down, and the spring self-locking device 5 will prevent the ramp from shrinking, thus achieving an automatic fixing effect. Furthermore, its length can be extended by overlapping. When the width of the construction ramp is insufficient, this construction ramp can be spliced ​​horizontally. The spliced ​​construction ramps are fixed horizontally by using the limiting post 451 on the limiting plate 45 in conjunction with the limiting hole 13.

[0037] This utility model provides a quick-release prefabricated construction ramp that is easy to install and dismantle, convenient to use, easy to lay on stair passages, can protect the steps from damage, and can be adapted to different step sizes.
