[0023] See also Figure 1-5 As shown, a steel scaffold for construction engineering comprises a plurality of uprights 1, a work board body 3 and an outer frame 10, wherein the number of uprights 1 is several, a cross bar 2 is fixedly connected to the surface of the uprights 1, and adjacent cross bars 2 can be connected by the cross bar 2, a diagonal brace is installed on the surface of the uprights 1, a fixing frame 4 is fixedly connected to the surface of the work board body 3, a hook 5 is fixedly connected to the surface of the fixing frame 4, and the inner surface of the hook 5 is in contact with the surface of the cross bar 2, a feeding port 6 is provided on the top of the work board body 3, a rectangular plate 7 is installed on the top of the work board body 3 through a spring hinge, a through groove is provided on the top of the rectangular plate 7, a cavity 8 is provided inside the rectangular plate 7, and the surface of the rectangular plate 7 is in contact with the feeding port 6. The inner wall of the opening 6 is in contact with each other, the through groove is connected with the cavity 8, and a sealing mechanism 9 is installed inside the cavity 8. The sealing mechanism 9 can seal the through groove to reduce the possibility of tools on the work board body 3 falling off. The surfaces on both sides of the outer frame 10 are fixedly connected with extension plates 11, and both sides of the top of the extension plate 11 are fixedly connected with limit plates 12. The bottom of the work board body 3 is provided with a limit groove 13, and the surface of the limit plate 12 is slidably connected with the inner wall of the limit groove 13. Positioning grooves are provided on both sides of the top of the work board body 3, and the positioning pins 14 are detachably connected inside the positioning grooves. The positioning pins 14 slide through the extension plate 11, thereby further fixing the position of the extension plate 11;

[0024] A top plate 16 and a bottom plate 15 are fixedly connected to the upper and lower parts of the surface of one side of the outer frame 10, respectively. A screw rod 17 is rotatably connected to the top of the bottom plate 15. The top of the screw rod 17 is rotatably connected to the bottom of the top plate 16. A first gear plate 18 is fixedly sleeved on the upper part of the surface of the screw rod 17. An L-shaped plate is fixedly connected to the bottom of the top plate 16. A driving mechanism 20 is installed at the bottom of the inner surface of the L-shaped plate. A slide plate 19 is threadedly sleeved on the surface of the screw rod 17. A slide groove is provided on the surface of the outer frame 10. The surface of the slide plate 19 is slidably connected to the inner wall of the slide groove. A storage frame 21 is fixedly connected to the surface of the slide plate 19. Vertical plates 22 are fixedly connected to both sides of the top of the storage frame 21. The surface of the vertical plate 22 is slidably connected to the inner wall of the outer frame 10. A connecting rod 23 is fixedly connected to the top of the vertical plate 22. By cooperating with the vertical plate 22 and the connecting rod 23, the screw rod 17 can be unfolded while the storage frame 21 rises, so that the materials placed inside the storage frame 21 can rise smoothly.

[0025] The sealing mechanism 9 includes a rotating shaft 91, a rotating disk 92 and a sealing plate 93. The rotating shaft 91 rotates and penetrates the working board body 3. The sealing plate 93 is fixedly connected to the top of the rotating shaft 91, and the rotating disk 92 is fixedly connected to the bottom of the rotating shaft 91. The bottom of the rotating disk 92 contacts the bottom of the inner wall of the cavity 8. When the staff rotates the sealing plate 93, the rotating disk 92 can be driven to rotate through the rotating shaft 91. At this time, the through groove can be exposed, and the staff can transport materials such as steel pipes through the through groove. When the scaffold is in normal use, the through groove is sealed by the rotating disk 92 to reduce the risk of tools falling. The center of the inner wall of the cavity 8 is consistent with the center of the rotating shaft 91, and the height of the top of the rotating shaft 91 is equal to the height of the top of the rectangular plate 7. Based on this, it is convenient for the staff to rotate the sealing plate 93 to drive the rotating shaft 91 and the rotating disk 92 to rotate, so that the through groove can be exposed. In this process, the staff does not need to stand at the edge of the working board body 3, thereby increasing the safety of the scaffold when in use.

[0026] More preferably, the staff can install a railing on the top of the fixing frame 4 according to actual needs, so as to control the range of the staff's activities on the work board body 3, thereby improving the safety of the scaffolding when in use.

[0027] The driving mechanism 20 includes a motor 201, a driving shaft 202 and a second gear plate 203. The motor 201 is fixedly connected to the bottom of the inner surface of the L-shaped plate, the driving shaft 202 is fixedly connected to the output shaft of the motor 201, and the second gear plate 203 is fixedly sleeved on the surface of the driving shaft 202. The second gear plate 203 is meshed with the first gear plate 18. When the staff starts the motor 201, the driving shaft 202 drives the second gear plate 203 to rotate. Accordingly, the screw rod 17 rotates with the first gear plate 18 to adjust the height of the slide plate 19 so as to transport the material.

[0028] Working principle: When installing the scaffold, the staff can first install the work board body 3 and the fixing frame 4 by using the hook 5 in conjunction with the cross bar 2, and then the staff can push the outer frame 10 horizontally to the bottom of the work board body 3. At this time, the limit plate 12 and the limit groove 13 can be used in conjunction to limit the position of the outer frame 10. After that, the staff can further fix the position of the outer frame 10 and the extension plate 11 by using the positioning pin 14 in conjunction with the positioning groove. Finally, the staff can install the diagonal brace on the surface of the vertical pole 1 to support the state of the scaffold.

[0029] When the present scaffold is in use, the staff stand on the work board body 3 to carry out the work. When it is necessary to transport materials such as steel pipes to the work board body 3, the staff standing on the work board body 3 rotates the sealing plate 93, and the turntable 92 rotates accordingly, the through slot can be exposed, and the staff below can pass one end of the steel pipe through the through slot to the top of the work board body 3. When it is necessary to transport materials such as bricks, the staff below can place the materials inside the storage frame 21 and start the motor 201. The screw rod 17 rotates accordingly to drive the slide plate 19 and the storage frame 21 to rise. During this process, the vertical plate 22 and the connecting rod 23 can flip open the rectangular plate 7 so that the materials can be better transported to the top. Finally, the staff takes out the materials in the storage frame 21 to carry out construction work. After the staff takes out the materials and starts the motor 201 for reverse operation, the storage frame 21 can drop to the initial position. At this time, the rectangular plate 7 can be automatically closed under the action of the spring hinge to increase the safety of the present scaffold when in use.
