It is particularly troublesome to support the wall top surface of the above-mentioned shape, and it is impossible to achieve synchronous adjustment of the support. Therefore, a reinforced support formwork for housing construction projects is needed. Utility Model Content

[0023] Example

[0024] The wall top of the building can be supported only by using a steel pipe to support the bottom of the support plate vertically on the ground. However, on the one hand, the support area of ​​the support plate is limited. When a wall top surface with a large area needs to be supported, a large support plate needs to be used. There is no structure that can adjust the support area of ​​the support plate. On the other hand, the middle of the wall top surface of some buildings is parallel to the ground, while the two sides are symmetrically arranged inclined surfaces. It is particularly troublesome to support the wall top surface of the above-mentioned shape, and it is impossible to achieve synchronous adjustment of the support.

[0025] To do this, see Figure 1-4 The utility model provides a reinforced support formwork for housing construction engineering, comprising: a support upright 1, a mounting base 2 is fixedly connected to the bottom end of the support upright 1, mounting holes are opened on the four sides of the mounting base 2, a lifting seat 12 with an I-shaped cross section is slidably connected in the moving channel provided on the support upright 1, a lifting column 11 is fixedly connected to the top of the lifting seat 12, the top of the lifting column 11 movably passes through the support upright 1, and is fixedly connected to a top plate 3, and folding plates 4 are rotatably connected to both side walls of the top plate 3;

[0026] It also includes a synchronous unfolding structure 5 and a lifting transmission structure 6. The synchronous unfolding structure 5 is installed at the bottom ends of the two folding plates 4 and is connected to the lifting seat 12. The synchronous unfolding structure 5 can increase the supporting area of ​​the top plate 3 on the one hand, and can make the two folding plates 4 convenient for supporting the inclined top surface of the indoor building with different inclination angles on the other hand.

[0027] The lifting transmission structure 6 is installed on the lifting seat 12 and the lifting column 11, and is connected to the supporting upright 1. The lifting transmission structure 6 can realize the manual lifting operation of the top plate 3 to meet the needs of supporting the top and wall surfaces of indoor buildings of different heights.

[0028] Further as Figure 1-4 As shown, it is worth specifically explaining that in order to be able to support a wider range of parallel surfaces of the interior wall top of the building, and also to support the wall top surface whose middle part is parallel to the ground and whose two sides are symmetrically arranged with inclined surfaces, a synchronous unfolding structure 5 is provided, including two symmetrically arranged L-shaped connecting rods 51 fixedly connected to the outer side of the lifting seat 12, the top ends of the L-shaped connecting rods 51 are fixedly connected to the bottom end of the top plate 3, the L-shaped connecting rods 51 are rotatably connected with screw rods a52, the top ends of the screw rods a52 are rotatably connected to the bottom end of the top plate 3, and the bottom ends of the screw rods a52 extend to the L-shaped connecting rods 51. The bottom of the worm wheel 53 is fixedly connected with a worm gear 53, the outer sides of the worm gear 53 are meshedly connected with worms 54, the mounting shaft holes of the two worm gears 54 are fixedly connected with the same connecting shaft 56, the connecting shaft 56 is rotatably connected to the outer sides of the two L-shaped connecting rods 51 through two inverted L-shaped bearing seats 55, one end extension of the connecting shaft 56 is fixedly connected with a handwheel a57, the outer sides of the two screw rods a52 are threadedly connected with movable blocks 58, the movable blocks 58 are slidably sleeved on the outer sides of the L-shaped connecting rods 51, the two movable blocks 58 are hinged on the opposite sides with push-pull rods 59, and the top ends of the push-pull rods 59 are hinged to the bottom of the folding plate 4.

[0029] The movable block 58 is provided with a movable opening which cooperates with the sliding sleeve of the L-shaped connecting rod 51 .

[0030] Further as Figure 1-4 As shown, it is worth specifically explaining that, in order to facilitate the support of the top plate 3 for the top surfaces of the interior walls of buildings at different heights, a lifting transmission structure 6 is provided, including a screw b61 threadedly connected in a threaded channel provided on the inner side of the lifting column 11 and the lifting seat 12, the bottom end of the screw b61 is rotatably connected to the inner bottom wall of the moving channel, and extends to the cavity provided at the bottom of the supporting upright 1, and is fixedly connected to a bevel gear a62, the outer side of the bevel gear a62 is meshingly connected to a bevel gear b63, the mounting shaft hole of the bevel gear b63 is fixedly connected to a rotating shaft 64, the rotating shaft 64 is rotatably connected to the supporting upright 1, and the end of the rotating shaft 64 away from the bevel gear b63 extends to the outer side of the supporting upright 1, and is fixedly connected to a handwheel b65.

[0031] The length of the threaded channel provided on the inner side of the lifting seat 12 is shorter than the length of the threaded channel provided on the inner side of the lifting column 11 .

[0032] In summary: when the reinforced support formwork for housing construction is used, the mounting base 2 can be fixed to the ground by bolts, and the bevel gear b63 is rotated by the hand wheel b65, so that the bevel gear a62 is driven, and the screw rod b61 is rotated. Since the screw rod b61 is threadedly connected with the lifting column 11 and the lifting seat 12, the top plate 3 is moved up and supported on the top surface of the wall to be supported indoors. If the supporting area of ​​the top plate 3 is to be increased, the two worms 54 connected to the connecting shaft 56 can be rotated by the hand wheel a57, so that the two worm wheels 53 rotate in the same direction at the same time. When the two screw rods a52 rotate in the same direction at the same time, because the screw rods a52 are threadedly connected to the movable block 58, and then cooperate with the push-pull rod 59, the two folding plates 4 can be parallel to the top plate 3, thereby expanding the supporting area. Secondly, when it is necessary to support the top surface of a wall whose middle part is parallel to the ground and whose two sides are symmetrically inclined, the bevel gear b63 can be rotated by the hand wheel b65. The same principle as above makes the inclination angle of the two folding plates 4 adjustable, so as to support the top surface of the wall of this shape, thereby greatly improving the application range of the support formwork structure.
