The outer sides of the four guide columns 6 are slidably connected with a carrying outer frame 7;

[0035] When the carrying outer frame 7 moves downward, the building materials placed on the inner side of the carrying frame 1 and between the two hollow oblique frames 2 are compressed and fixed. A T-shaped pressure plate 8 is fixed on the inner side of the carrying outer frame 7 and between the two hollow oblique frames 2. Expansion plates 10 are provided on both sides of the lower end of the T-shaped pressure plate 8. In the process of gradual downward movement of the carrying outer frame 7, in order to drive the two expansion plates 10 to slowly expand according to the inclination of the two hollow oblique frames 2, thereby expanding the contact surface for squeezing the building materials, a plurality of sliding columns 9 are evenly fixed to the lower end of the T-shaped pressure plate 8. The expansion plates 10 are slidably connected to the sliding columns 9. The outer side of each sliding column 9 is symmetrically sleeved with a first spring 11, one end of the first spring 11 is fixed to the expansion plate 10, and the other end of the first spring 11 is fixed to the T-shaped pressure plate 8;

[0036] In order to facilitate manual adjustment of the height position of the carrying outer frame 7 and drive the carrying outer frame 7 to move up and down, the upper end of the carrier frame 1 and the lower end of the first top plate 4 are rotatably connected to a screw rod 12, the upper ends of the screw rod 12 respectively penetrate the carrying outer frame 7 and the first top plate 4 and are rotatably connected to the first top plate 4, the screw rod 12 is threadedly connected to the carrying outer frame 7, and a handle 22 is fixed to the top of the screw rod 12. When the handle 22 is grasped and the screw rod 12 is rotated to drive the carrying outer frame 7 to move up and down under the guidance of the guide column 6, in order to limit and fix the position of the carrying outer frame 7, a limit assembly is provided between the screw rod 12 and the first top plate 4;

[0037] Specifically, the limiting assembly includes a first spur gear 13. The first spur gear 13 is fixed to the outside of the screw 12 and located at the upper end of the first top plate 4. A gear groove 14 is opened inside the first top plate 4 and located on the outside of the first spur gear 13. A second spur gear 15 is slidably connected to the inside of the gear groove 14.

The lower end of the second spring 16 is fixed to the first top plate 4.

[0038] Example 2:

[0039] The building material stacking bracket provided in Example 1 is further optimized. Specifically, Figure 1 、 4As shown in Figures 5 and 6, after the building materials are pressed and consolidated by the carrying outer frame 7, the T-shaped pressure plate 8 and the expansion plate 10, when one end of the building material extends to the outside of the carrier frame 1, in order to facilitate the protection of the end of the building material, the inner sides of the two hollow oblique frames 2 are movably connected with hollow support tubes 17, and the interiors of both ends of the carrying outer frame 7 are provided with two arc-shaped through grooves 21. The outer sides of the hollow support tubes 17 are fitted with the inner sides of the arc-shaped through grooves 21, so that the hollow support tubes 17 can be conveniently raised and lowered synchronously with the carrying outer frame 7. In order to prevent the hollow support tubes 17 from falling out from the inner sides of the hollow oblique frames 2, the outer sides of both ends of each hollow support tube 17 are fixed with limit rings 18, and the limit rings 18 are fitted with the carrying outer frame 7;

[0040] Each hollow support tube 17 is slidably connected to a slide rod 19 on the inside, and a third spring 20 is fixed to one end of the slide rod 19. The end of the third spring 20 away from the slide rod 19 is fixed to the hollow support tube 17. An elastic cloth cover 23 is provided between the two slide rods 19 and on the outside of the carrying outer frame 7. By pulling out the slide rod 19, the elastic cloth cover 23 can be easily put on the end of the building material extending to the outside of the carrier frame 1, thereby effectively protecting the end of the building material;

[0041] The use process of the building material stacking bracket provided by the present invention is as follows: after the building materials are stacked inside the carrier frame 1 and located between the two hollow oblique frames 2, the second flat gear 15 is pressed to slide into the inner side of the gear groove 14, thereby releasing the meshing of the second flat gear 15 and the first flat gear 13, so that the handle 22 can be grasped to rotate the screw 12. The screw 12 is threadedly connected to the carrying outer frame 7 to drive the carrying outer frame 7 to move downward under the guidance of the guide column 6. The elastic characteristics of the first spring 11 facilitate the pushing out of the expansion plate 10, so that the two expansion plates 10 gradually expand as the carrying outer frame 7 moves downward, thereby pressing and securing the building materials.

[0042] After the outer frame 7 is moved downward and the building materials are pressed and fixed, the teeth of the first flat gear 13 and the second flat gear 15 are aligned, and the second flat gear 15 is released. The elastic force of the second spring 16 drives the second flat gear 15 to reset, so that the second flat gear 15 is re-engaged with the first flat gear 13, thereby limiting the rotation of the screw 12, thereby fixing the height position of the outer frame 7 and completing the fixing of the building materials;

[0043] During the lifting and lowering process of the carrying outer frame 7, the hollow support tube 17 always follows the movement of the carrying outer frame 7 through the arc-shaped through groove 21. After the building material is fixed, when one end of the building material extends to the outside of the carrier frame 1, the slide rod 19 is pulled out to facilitate the elastic cloth cover 23 to be put on the end of the building material, thereby protecting the extended end of the building material.
