For such large-area, multi-functional, load-different, and structurally different buildings, uneven settlement, temperature shrinkage, and complex shapes will have a huge adverse impact on the building.

[0003] The traditional construction method of post-casting strips is to use "wooden formwork + steel pipe support system". This method has the following problems: ① the formwork system at the post-casting strip needs to be set up independently and for a long time, which seriously affects the space traffic and reduces the efficiency of other processes. ② the formwork system at the post-casting strip is set up for a long time, the material turnover rate is low, and the economy is low. Therefore, it is necessary to propose a post-casting strip without support system formwork construction device to solve the above technical problems. Utility Model Content

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] As a further improvement of the above solution, the embedded part is threadedly connected to the support plate and the first fixing nut respectively.

[0009] As a further improvement of the above scheme, a reinforcing bar is provided at the lower end of the bottom mold, and the reinforcing bar is a steel square tube or a steel bar; the lower end of the embedded part is sequentially inserted into the support plate, the bottom mold, the reinforcing bar and the first fixing nut.

[0010] As a further improvement of the above scheme, the lower end of the embedded part is inserted into the support plate, the bottom mold, the reinforcement bar and the second fixing nut assembly in sequence; the second fixing nut assembly includes a lifting section, a connecting section is provided at the lower end of the lifting section, and hooks are provided at the upper ends of both sides of the lifting section.

[0011] As a further improvement of the above solution, the connecting section and the lifting section are an integral structure and are hook-welded to the lifting section.

[0012] As a further improvement of the above solution, the connecting section and the lifting section are connected to the embedded part by threads. Beneficial Effects

[0013] The utility model provides a post-casting strip non-support system formwork construction device, which does not require a support frame at the post-casting strip, thereby improving the space traffic rate, improving the material turnover rate, and being able to be reused, thereby generating good economic and social benefits.

[0014] The utility model is simple to manufacture: the device is made of ordinary materials and the manufacturing process does not require special processes, which is simple and convenient; low cost: the device has low manufacturing cost, and the materials required for manufacturing are all ordinary consumables, which has good economic benefits; environmental protection and saving: the device is reusable, not easy to damage, does not cause pollution, and has good social benefits.

[0015] The utility model is easy to operate: when pouring floor slab concrete, the load-bearing embedded parts are fixed at predetermined positions, and after the concrete on both sides of the post-casting zone reaches the requirements, a lifting vehicle or a stepladder is used to install the corresponding holes of the slab bottom formwork in place.

[0016] Improve efficiency: This method uses the axial tension of the load-bearing embedded parts to cleverly fix the bottom formwork at the bottom of the first poured concrete, solving the space constraints caused by the erection of the support to improve the overall construction efficiency.
