[0020] The beam formwork lifting mechanism includes a slot opened at the top of the side wall of the frame steel formwork, with template slots 3 fixed to the frame steel formwork vertically arranged on both sides of the slot, a lifting formwork 4 is inserted into the template slot 3, a horizontally arranged beam formwork 5 is fixed to the upper end of the lifting formwork 4, and a horizontally arranged connecting plate 6 is fixed to the lower end of the lifting formwork 4, and a hydraulic rod 7 connecting the connecting plate 6 and the side wall of the template slot 3 is arranged between the two.

[0021] The utility model adjusts the height of the beam template 5 to meet the elevation by arranging a lifting mechanism on the frame steel template, thereby overcoming the problems of difficult adjustment, high labor intensity and impact on progress and construction quality in the existing template support when the elevations of the beams passing through the columns in four directions at the junction of beams and columns are inconsistent.

[0022] The frame steel formwork includes four column formworks 11. Two vertically distributed splicing ear plates 12 and a U-shaped clamping plate 13 are fixed to the outer sides of the two vertical main keels 2 of the column formwork 11. A vertically arranged short pin 14 is fixed between the two splicing ear plates 12. The side wall ends of the U-shaped clamping plate 13 are screwed with locking screws 15.

[0023] Motors 8 are fixed to the inner bottom of the two vertical main keels 2 of the column formwork 11, a vertically arranged rack 9 is fixed to the base plate 1, and a power gear 10 meshing with the rack 9 is connected to the output shaft of the motor 8.

[0024] The combined structure of the frame steel formwork is easy to install. At the same time, the engaging structure of the motor 8 and the rack 9 drives the column formwork 11 to adjust its height to ensure that the column formwork 11 is flush and reaches the elevation position.

[0025] The connecting plate 6 is a U-shaped structure, and a transverse main purlin 19 is provided on the lower end face of the beam formwork 5. A column 20 is provided between the transverse main purlin 19 and the connecting plate 6 to fix the two, and a diagonal brace 21 is provided between the column 20 and the transverse main purlin 19 to fix the two.

[0027] Several locking hoops distributed up and down are provided on the outside of the vertical main keel 2. Each locking hoop includes two clamping rods I16 distributed front and back and bent upward at both ends into a U-shape, and two clamping rods II17 distributed left and right and bent upward at one end into a U-shape.

At this time, the motor 8 is started, and the motor 8 drives the power gear 10 to rotate. Since the rack 9 is in a stationary state, under the meshing action of the rack 9 and the power gear 10, the motor 8, the vertical main keel 2 and the column template 11 rise synchronously until the column template 11 is flush, and then the motor 8 is turned off, and a wedge-shaped pad is installed at the gap between the vertical main keel 2 and the bottom plate 1 for fixing; then the hydraulic rod 7 is turned on, and the connecting plate 6 drives the lifting template 4 to rise and fall at the same time, so that the height of the beam template 5 is raised to the designed height, and the hydraulic rod 7 is turned off to complete the adjustment of the elevation of the beam template 5. Subsequently, the remaining main keels are installed between the vertical main keels 2 on both sides of each column template 11, and the column template 11 is locked by the clamping rod I and the clamping rod II through the latch 18. During the locking process, the column template 11 and the beam template 5 are proofread by the spirit level 22 and the verticality detector 23 to meet the flatness requirements, and finally the through-wall bolts are installed.

[0034] In the specific implementation process, two connecting ear plates 25 distributed up and down are fixed on the outer side wall of the template slot 3, the hydraulic rod 7 is placed upside down, and the cylinder body of the hydraulic rod 7 is connected to the connecting ear plates 25 through a pin shaft.
