[0023] See also Figures 1 to 5The utility model provides a technical solution: an assembly structure of a basement exterior wall formwork without openings and a finished steel joint strip 10, comprising: a floor 1 and a fixed steel strip 5, a plurality of fixed steel strips 5 are fixedly installed on the upper surface of the floor 1, a plurality of baffles 6 are arranged above the floor 1, the floor is used to block the poured cement, and due to the slow flow rate of cement, a small amount of cement may flow out from the gap, and a steel joint strip 10 is clamped between every two baffles 6, and the steel joint strip is used to connect between the baffles 6 and the baffles 6, and also fills the gap between the baffles 6 and the baffles 6 to ensure that less cement flows out, and effectively fixes the baffles 6 on the fixed steel strip 5 to form a wall shape, and every two steel joint strips Steel cross blocks 11 are clamped between the seam strips 10. The steel cross blocks 11 are arranged at the intersection of the rigid seam strips to connect the steel seam strips 10 on four sides, so that the formwork of the exterior wall is more integrated and cement is not easy to flow out. A cylindrical groove 12 is provided on one side of each steel cross block 11 and one side of each steel seam strip 10. The cylindrical groove 12 is adapted to the clamp 19. A transverse support device 2 is provided on one side of the cylindrical groove 12. The support device firmly presses the rigid seam strips and the steel cross blocks 11 on the fixed steel pipe 4, and indirectly presses the baffle 6 tightly to prevent it from leaking. Side panels 8 are provided on one side of the left and right baffles 6.

[0024] Specifically, the lateral support device 2 includes an outer tube 21, a telescopic rod 20 and two clamps 19, the clamps 19 are clamped with the cylindrical groove 12, the outer tube 21 and the telescopic rod 20 are arranged between the two clamps 19, and the outer tube 21 is threadedly connected with the telescopic rod 20. When not in use, the telescopic rod 20 and the outer rod can be rotated. When it is needed, the combined length of the telescopic rod 20 and the outer rod needs to be shortened first, and then the clamp 19 is clamped into a cylindrical groove 12 and the telescopic rod 20 is rotated for adjustment until the other clamp 19 is clamped into the opposite cylindrical groove 12, and the telescopic rod 20 is continued to be screwed until the telescopic rod 20 presses the two sides tightly, and one end of the outer tube 21 and one end of the telescopic rod 20 are both rotatably connected with the clamp 19, and the rotatably connected clamp 19 allows the telescopic rod 20 to be still screwed after the clamp 19 is clamped into the cylindrical groove 12;

[0025] Secondly, the steel cross block 11 is fixedly connected with the steel rod 3 on all sides, and the steel seam strip 10 is provided with a through groove 22, which penetrates the steel seam strip 10, and the steel rod 3 extends into the steel seam strip 10 and is slidably connected therewith. Since the steel cross block 11 is arranged at the intersection of the steel seam strip 10, the steel seam strips 10 on four sides can be connected together;

[0026] In addition, a slot is provided on one side of the side panel 8, and a rod assembly 9 is clamped in each slot. A steel pipe 4 is provided between the two rod assemblies 9, and nuts 7 are threadedly connected at both ends of each steel pipe 4. After installing the rod assembly 9, rotate the nut 7 until the rod assembly 9 is inserted into the slot and the nut 7 cannot be twisted. The nut 7 effectively clamps the rod assembly 9.

[0027] In addition, the clamping rod assembly 9 includes a clamping rod body, each clamping rod body is clamped with a clamping slot, rectangular slide grooves 15 are opened at both ends of the clamping rod body, a rectangular slider 13 is slidably connected in each rectangular slide groove 15, a cylindrical slide groove 14 runs through the two rectangular slide grooves 15, and the two rectangular slide grooves 15 are connected through a cylindrical slide groove 14.

[0028] Finally, a spring 16 is arranged in the cylindrical slide groove 14, and the spring 16 provides a force for tightening the steel pipe 4. Both ends of the spring 16 are fixedly connected with a cylindrical slide bar 17, and the two cylindrical slide bars 17 are respectively fixedly connected to the two rectangular sliders 13. The setting of the spring 16, the cylindrical slide bar 17 and the fixed block enables the spring 16 to generate a force to pull the rectangular slider 13 inward. At this time, the elastic force is used for contraction, so that the two steel pipes 4 and the fixed steel bar 5 fit more closely. A limiting through hole 18 is opened on each rectangular slider 13, and a steel pipe 4 is inserted into the limiting through hole 18. After the steel pipe 4 is inserted into the limiting through hole 18, it contracts inwardly under the action of the spring 16, which effectively makes the steel pipe 4 and the fixed steel bar 5 fit more closely.

[0029] When the device is working, first install the bottom baffle 6, and then install the fixed steel bar 5 on the bottom baffle 6. Each time a pair of fixed steel bars 5 is installed, it needs to be supported by the transverse support device 2. At this time, it only needs to be lightly supported. Then insert the upper baffle 6. Before inserting the baffle 6, consider whether it is necessary to use the steel cross block 11. If it is necessary, first install the cross block, then install the steel seam strip 10, then install the two baffles 6 above the steel cross block 11 and finally insert the steel seam strip 10 between the two baffles 6. Then tighten the transverse support device 2 so that the steel seam strip 10 presses the baffle 6 tightly against the fixed steel bar 5, then install the side panel 8, and finally install the clamping rod assembly 9 and the steel pipe 4. In this process, there is no need to punch holes in the baffle 6, which effectively saves the time for punching holes.
