[0023] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0024] Reference Figures 1 to 4 An example of the utility model provides a post-cast strip force transmission device, including a force transmission component 1 and a protective component 2. The force transmission component 1 includes a first force transmission rod 11 and a second force transmission rod 12. One end of the first force transmission rod 11 and one end of the second force transmission rod 12 are telescopically adjustable. The other end of the first force transmission rod 11 and the other end of the second force transmission rod 12 are respectively connected to the concrete structures on both sides of the post-cast strip. The protective component 2 is laid on the post-cast strip.

[0025] Specifically, a threaded hole 111 is provided at one end of the first force transmission rod 11 , and an external thread 121 screwed into the threaded hole 111 is provided at one end of the second force transmission rod 12 .

[0026] After the post-cast strip of the floor slab is left, the external thread 121 at one end of the second force transmission rod 12 is screwed into the threaded hole 111 at one end of the first force transmission rod 11, so that the length of the first force transmission rod 11 and the second force transmission rod 12 after connection is shorter than the width of the post-cast strip, so as to facilitate the first force transmission rod 11 and the second force transmission rod 12 to be placed in the post-cast strip. Then, the external thread 121 at one end of the second force transmission rod 12 is screwed out of the threaded hole 111 at one end of the first force transmission rod 11 to adjust the length of the first force transmission rod 11 and the second force transmission rod 12 after connection, so that the other end of the first force transmission rod 11 and the other end of the second force transmission rod 12 are respectively in contact with the concrete on both sides of the post-cast strip. Then, the protective component 2 is laid on the post-cast strip, the force transmission component 1 can support and transmit force to the post-cast strip, and the protective component 2 can protect the post-cast strip, thereby ensuring the stability and safety of the entire building structure. Moreover, before the construction of the post-cast strip structure, the force transmission component 1 and the protective component 2 can be recycled for easy recycling.

[0027] In some preferred embodiments, support plates 13 are provided at the opposite ends of the first force transmission rod 11 and the second force transmission rod 12, and the support plates 13 abut against the inner side of the post-cast slab. The support plates 13 can increase the force-bearing area between the first force transmission rod 11 and the second force transmission rod 12 and the post-cast strip, thereby avoiding stress concentration on the inner side of the post-cast strip caused by the ends of the first force transmission rod 11 and the second force transmission rod 12 and causing structural damage to the inner side of the post-cast strip.

[0028] Furthermore, the first force transmission rod 11 and the second force transmission rod 12 are both steel pipes, and the support plate 13 is a steel plate. The first force transmission rod 11 and the second force transmission rod 12 are both rotatably connected to the support plate 13. When the first force transmission rod 11 and the second force transmission rod 12 are threadedly connected, the first force transmission rod 11 or the second force transmission rod 12 rotates, so that the support plate 13 will not rotate relative to the concrete structure on the side of the post-cast strip, thereby ensuring that the support plate 13 can abut against the concrete structure on the side of the post-cast strip.

[0029] Furthermore, the first force transmission rod 11 and the second force transmission rod 12 are both perpendicular to the support plate 13, thereby ensuring that the support plate 13 is in full contact with the concrete structure on the side of the post-cast strip, thereby improving the stability of the entire building structure.

[0030] In some preferred embodiments, the protective component 2 includes a protective steel plate 21 and a plurality of steel bars 22. The plurality of steel bars 22 are arranged at the bottom of the protective steel plate 21. The protective steel plate 21 is laid on the post-cast strip. The plurality of steel bars 22 are clamped on the inner sides of the post-cast strip. Construction workers and vehicles can pass through the protective steel plate 21 to facilitate the material transfer between various construction areas. Moreover, the plurality of steel bars 22 can limit the protective steel plate 21 to prevent the protective steel plate 21 from being displaced due to the construction load when the construction workers and vehicles pass by.

[0031] Specifically, a plurality of steel bars 22 are symmetrically arranged along the center line of the protective steel plate 21 , so that the forces on the steel bars 22 and the inner sides of the post-cast strip are balanced, thereby preventing the protective steel plate 21 from being skewed.

[0032] Furthermore, the protective steel plate 21 extends out on both sides and overlaps on the concrete on both sides of the post-cast strip, which can increase the force-bearing area between the protective plate and the concrete structure on both sides of the post-cast strip, reduce the concentrated force on the concrete structure on both sides of the post-cast strip, and thus improve the stability of the concrete structure on both sides of the post-cast strip.

[0033] Furthermore, the protective steel plate 21 and the steel bar 22 are welded, so that parts of different shapes can be conveniently connected together, the connection is firm, the manufacturing process is simple, and the operation is convenient.

[0034] Furthermore, the top of the protective steel plate 21 is provided with anti-skid grooves, which can increase the friction between the construction workers or vehicles and the protective steel plate 21, thereby preventing the construction workers from slipping or the vehicle from skidding, and improving safety.

[0035] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
