[0032] The two box cross beams 1 are fixedly connected to two mutually parallel cross beam guide rails 110 in the vertical direction on the outside, and the cross beam guide rails 110 extend to the outside of the outer frame. One push rod beam 3 is slidably connected to the left cross beam guide rail 110, and the other push rod beam 3 is slidably connected to the right cross beam guide rail 110; the movable blocking plate 6 is installed in the outer frame of the box body, and is fixedly connected to one end of a plurality of longitudinally parallel push rods 604, and the other end of the push rod 604 passes through the web opening 108 of the box cross beam 1 and is connected to the push rod beam 3.

[0035] The movable blocking plate 6 is arranged between two partitions 5, or between the partition 5 and the longitudinal beam. When pouring concrete, the position of the movable blocking plate 6 is adjusted. After it is in place, the fixing nuts 603 and the blocking plate locking nuts 605 on the push rod 604 are tightened, so that the two blocking plate locking nuts 605 clamp the push rod beam 3 in front and back;

[0036] The end of the push rod beam 3 is locked and connected with the flat plate pin hole 107 on the head flat plate 106 at the end of the box H steel cross beam 1 through the limit plate positioning hole 304 on the limit plate 303 through the pin 111, and then the connected movable blocking plate 6 is accurately positioned and locked through the push rod beam 3, so as to realize the accurate positioning of the ends of multiple precast concrete columns C1 or beams C2; the push rod beam 3 is pushed to move outward on the cross beam guide rail 102, and the push rod 604 drives the blocking plate vertical plate 601 to quickly separate from the precast concrete column C1 or beam C2;

The beam surface stiffening plates 102 are provided with lifting holes 103 to facilitate the lifting and transportation of the box body. The transverse beam connecting plate 104 is provided with transverse beam connecting plate bolt holes 105, and the end of the box body steel longitudinal steel beam 2 is provided with a longitudinal beam connecting plate 201, which is provided with a longitudinal beam connecting plate bolt hole 202. The longitudinal and transverse beam connecting bolts 203 pass through the transverse beam connecting plate bolt holes 105 and the longitudinal beam connecting plate bolt holes 202. After tightening, the box body transverse steel beam 1 and the box body longitudinal steel beam 2 are fixedly connected to form a structure as shown in FIG. Figure 4 The shown box mold is the outer frame of the box.

[0038] like Figure 4 , Figure 5 , Fig. 9 , Fig.10 As shown, the upper flange of the box body transverse steel beam 1 is provided with multiple rows of transverse beam upper flange bolt holes 109, the end of the partition 5 is provided with an end fixing hole 501, and the connecting transverse beam bolt 703 of the connecting member 7 passes through the transverse beam upper flange bolt hole 109 and the connecting transverse beam hole 701 to achieve the connection between the connecting member 7 and the upper flange of the transverse steel beam 1. The connecting partition bolt 704 passes through the connecting partition hole 702 and the end fixing hole 501 of the partition 5, and the partition 5 can be connected to the upper flange of the steel transverse steel beam 1 through the connecting member 7 after the nut is locked.

[0039] like Figure 6 , Fig.12As shown, the blocking plate upright plate 601 of the movable blocking plate 6 is mainly used to block the end concrete of the precast concrete column C1 and the precast concrete beam C2 when the precast component concrete is poured. The blocking plate upright plate 601 has multiple beam and column reinforcement through holes 602 at predetermined positions. When pouring concrete, the precast concrete beam or column longitudinal reinforcement C3 passes through the beam and column reinforcement through holes 602 without affecting the concrete blocking; the push rod 604 is connected to the blocking plate upright plate 601 through the push rod fixing nut 603. When pouring concrete components with different precast beam and column sections, the blocking plate upright plate 601 can be quickly replaced; the push rod 604 passes through the web opening 108 of the box steel cross beam 1 and the push rod through hole 302 of the push rod beam 3, and the push rod 604 is fixed on the push rod beam 3 through the blocking plate locking nut 605. The position of the locking nut 605 can be adjusted to correspond to the end position of the precast concrete column C1 and the precast concrete beam C2 of different lengths.

Figure 1 , Figure 2 As shown on the right, when pouring the concrete of the precast concrete column C1 and the precast concrete beam C2, adjust the position of the locking nut 605, the position of the limit plate positioning hole 304 coincides with the position of the flat plate pin hole 107, and insert the pin 111 to lock and position. When the concrete pouring of the precast component is completed and separated from the box body, take out the pin 111, push the push rod beam 3 to move outward, and drive the movable blocking plate 6 to move outward and separate from the precast concrete column C1 and the precast concrete beam C2.

[0041] The precast concrete column C1 and the precast concrete beam C2 can be removed from the box when they reach the required strength. Before removing from the box, the pin 111 is taken out to push the push rod beam 3 to move outward. The push rod beam 3 moves on the beam guide rail 102 to link the blocking plate and the vertical plate 601 to separate from the precast concrete column and beam joint surface. Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown on the left side, the movable blocking plate 6 is separated from the precast concrete column C1 and the precast concrete beam C2, and then hoisted away from the box as a whole, completing the demoulding and boxing of the precast concrete column C1 and the precast concrete beam C2.

The connecting piece 7 is an L-shaped plate, the bottom plate is provided with a connecting cross beam hole 701, and the vertical plate is provided with a connecting partition hole 702. The connecting cross beam hole 701 of the connecting piece 7 is aligned with the bolt hole 109 on the upper flange of the beam, and the connecting cross beam bolt 703 is tightened. The connecting partition bolt 704 passes through the connecting partition hole 702 and the end fixing hole 501 of the partition 5, and the partition bolt 704 is tightened. In this way, the partition 5 is connected to the upper flange of the steel cross beam 1 through the connecting piece 7, as shown in FIG. Figure 1 , Figure 7 As shown, different partition spacings can be determined to correspond to different cross-sectional widths of the precast concrete columns C1 and precast concrete beams C2.

[0043] like Figure 7 As shown on the left and right sides, the inner side of the H-shaped steel of the box body steel longitudinal beam 2 is filled with a side pad B1 to make the inner side of the box body steel longitudinal beam 2 flat. The inner side of the box body steel longitudinal beam 2 is attached with a longitudinal beam side plugging plate 8 to form the inner cavity of the precast concrete column C1 or precast concrete beam C2 of the box mold side unit. By adjusting the width of the longitudinal beam side plugging plate 8, the required cross-sectional width of the precast concrete column C1 or precast concrete beam C2 can be adjusted; the height of the longitudinal beam side plugging plate 8 is flush with the top surface of the partition 5; Figure 4 , Figure 7 As shown, Figure 7 As shown, the lower part of the cavity between the partition 5 and the longitudinal beam side blocking plate 8, or between two adjacent partitions 5, is not provided with or is provided with spacers B2 of different heights, so that the cross-sectional heights of different precast concrete columns C1 or precast concrete beams C2 can be adjusted.

Different cross-sectional widths and heights of the precast concrete columns C1 or precast concrete beams C2 correspond to different heights and horizontal positions of the push rods 604 of the movable blocking plate 6. The push rods 604 pass through the cross beam web openings 108 and the push rod through holes 302, and are fixed to the push rod beam 3 with push rod fixing nuts 603.
