[0029] Furthermore, two sides of the U-shaped formwork 4 are vertically and correspondingly provided with wooden squares 7 , and the corresponding wooden squares 7 on the two side panels of the U-shaped formwork are fixed by second tension screws 8 .

[0030] Furthermore, back ribs 9 are respectively arranged between the wooden square 7 and the U-shaped template 4, and between the bottom template 2 and the U-shaped template 4, and the back ribs 9 arranged between the wooden square 7 and the U-shaped template 4 are perpendicular to the wooden square 7. It should be noted that the back ribs arranged on the side panels of the U-shaped template are arranged horizontally and perpendicular to the wooden squares.

[0031] Furthermore, in order to strengthen the connection strength between the poured wall and the beam, a notch 10 is provided on the bottom surface of the beam 1, and the opening of the U-shaped template 4 corresponds to the notch 10. At the same time, the top of the fixed steel bar 6 extends into the notch 10. The top of the steel beam can selectively extend into the notch.

[0032] Furthermore, in order to protect the cross beam, a top mold 11 is provided on the top surface of the cross beam 1, and the first tension screw 3 passes through the cross beam 1 and is fixed to the top mold 11. A gap is provided between the top mold and the lateral direction, that is, a cushion block (not shown in the figure) can be provided between the top mold and the cross beam.

[0033] Furthermore, in order to speed up the fixing efficiency of the second tie screw rod, the second tie screw rod 8 is fixed by a locking fastener.

[0034] Furthermore, a steel pipe 12 is laterally arranged on the outer side of the wooden square 7, and two steel pipes are fixed to a section of each second tension screw, and are respectively fixed to the upper and lower sides of the second tension screw, so as to strengthen the lateral fixation of the wooden square, and then strengthen the fixation of the U-shaped formwork. The steel pipe 12 is fixed to the second tension screw 8 by a locking fastener.

[0035] Specifically, the locking fastener includes a fixing buckle 13 in a "C" shape, which is directly buckled on the side wall of the wooden square. The second pair of tie rods passes through the fixing buckle, and the steel pipe passes through the fixing buckle in a direction perpendicular to the second pair of tie rods and is located above and below the second pair of tie rods (refer to Figure 2 as shown). Symmetrically arranged in the fixing buckle 13 are bearing platforms 14 that move towards the middle of the fixing buckle 13. The bearing platforms 14 are in an L shape with their openings corresponding to each other. The steel pipe 12 is placed on the bearing platforms 14, and the bearing platforms drive the steel pipe to move closer to the second pair of tie rods until they抵 against each other, thereby achieving the purpose of locking the steel pipe to the second pair of tie rods.

[0036] Further, a screwing sleeve 15 adapted to the second pair of tie rods 8 is provided through the middle of the fixing buckle 13. A driving sleeve 16 that can slide along its length is sleeved on the screwing sleeve 15, and the driving sleeve 16 drives the two bearing platforms 14 to move towards or away from each other. The length of the driving sleeve is less than that of the screwing sleeve. The screwing sleeve is provided with internal threads and is adapted to the second pair of tie rods. Compared with the prior art, when the fixing buckle locks and fixes the second pair of tie rods, it can also lock the steel pipe on the second pair of tie rods for fixation.

[0037] Further, in order to enable the driving sleeve to slide on the screwing sleeve, an annular guiding groove 17 is provided along the length direction on the side wall of the screwing sleeve 15. The driving sleeve 16 is sleeved on the guiding groove 17. The two ends of the guiding groove limit the driving sleeve to prevent it from detaching from the screwing sleeve. The driving sleeve 16 and the screwing sleeve 15 are fixed by a pin shaft 18. A plurality of pin holes are provided in the axial direction of the driving sleeve and the screwing sleeve. A gear 19 is sleeved at one end of the driving sleeve 16 facing the fixing buckle 13, and the end of the tooth of the gear 19 is flush with the outer side wall of the driving sleeve 16. It should be noted that: preferably, the driving sleeve is arranged at a position close to the middle of the screwing sleeve, refer to Figure 4 as shown. The end of the tooth of the gear 19 can be flush with the outer side wall of the driving sleeve 16, or can be located within the area of the outer side wall of the driving sleeve, that is, the outer contour diameter of the gear is smaller than the outer diameter of the driving sleeve. When installing the gear, an annular groove penetrating the end of the driving sleeve is opened at one end of the driving sleeve, and the gear is sleeved and fixed in the annular groove.

[0038] Furthermore, in order to realize the movement of the bearing platform, a slide groove 20 with a T-shaped cross section and vertically arranged is provided on the vertical plate of the fixing buckle 13. The slide groove is provided along the vertical plate of the fixing buckle and has a T-shaped cross section. The bearing platform 14 is rotatably connected to a driving block 22 through a connecting block 21 on one side of the vertical plate of the fixing buckle 13. The driving block 22 extends into the slide groove 20, and the T-shaped cross section of the slide groove can prevent the driving block from escaping from the slide groove. The driving block and the connecting block are rotatably connected. As one embodiment, the connecting block and the driving block are fixed by a bearing. A rack 23 is fixedly provided on one side of the two driving blocks 22. The two racks 23 are staggered and parallel to each other, that is, the racks are centrally symmetrically arranged with the axis of the screw sleeve as the center. In the process of the driving sleeve 16 sliding toward the fixing buckle 13, the two racks are meshed with the gear 19 and are respectively located on both sides of the gear 19. During operation, pass the fixing buckle through the second tension screw and buckle it on the wooden square. At the same time, the steel pipe passes through the fixing buckle and contacts the vehicle-mounted platform. Figure 2 As shown, at this time, the bearing platform is located above and below the steel pipe and distributed on the upper and lower sides of the second tension screw. At this time, the screwing sleeve is inserted into the second tension screw, screwed into the second tension screw, and gradually passes through the fixing buckle. When one end of the screwing sleeve contacts the wood, the driving sleeve is slid to insert it into the fixing buckle and make the gear mesh with the two racks. Then the driving sleeve is screwed to drive the gear to drive the rack to move, so that the bearing platform drives the steel pipe to move toward the second tension screw until the steel pipe is tightly against the second tension screw and the wood, thereby achieving the locking of the steel pipe, the second tension screw and the wood, and then the driving sleeve and the screwing sleeve are fixed by the latch. When the locking fastener needs to be removed, the latch is pulled out, the driving sleeve is screwed in the reverse direction, the steel pipe is loosened against the second tension screw and the wood, and then the driving sleeve is pulled out to disengage the gear and the rack, and then the screwing sleeve is screwed in the reverse direction to loosen the fixation of the second tension screw.
