[0025] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] See also Figure 1-5 The utility model is a concrete beam-slab structure without support and free formwork, including a base 1, with free formwork 2 placed on the front and rear sides of the top of the base 1, and side panels 3 placed on both sides of the top of the base 1, and the two side panels 3 are symmetrically arranged on both sides of the free formwork 2; an adjustment component is provided at the top of the free formwork 2, and the adjustment component includes a slide 4, which is opened at the top of the free formwork 2, and a slider 5 is slidably connected inside the slide 4, and a fixing hole 6 is opened at the top of the slider 5, and a supporting steel bar 7 is placed inside the fixing hole 6, and a placement groove 8 is opened inside the slider 5, and slides 9 are slidably connected on both sides of the placement groove 8, a spring 10 is fixedly connected between the two slides 9, and a block 11 is fixedly connected to one side of the slide 9, and a slot 12 is opened on the inner wall of the slide 4, and the other side of the block 11 passes through the slider 5 and extends to the inside of the slot 12.

[0028] Specifically: the slider 5 is slidably connected to the slide groove 4, and can slide smoothly to ensure that adjustment work can be carried out. The supporting steel bar 7 is in the shape of an I-beam. The purpose of this design is to facilitate the assembly of other non-removal formwork 2 and ensure that the concrete beam-slab structure without support and non-removal formwork can be suitable for assembly requirements of different heights. Two blocks are set in each group of blocks 11, which can ensure that the block 11 and the card groove 12 are more stable during the use of the block.

[0029] Example 2

[0030] See also Figure 1-5On the basis of Example 1, a through hole 13 is opened inside the side plate 3, and a bolt 14 is threadedly connected to one side of the through hole 13. Limiting holes 15 are opened on both sides of the disassembly-free formwork 2. One end of the bolt 14 passes through the through hole 13 and extends to the inside of the limiting hole 15. The supporting steel bars 7 are I-shaped, and there are three of them, which are used to fix two groups of disassembly-free formwork 2. There are six slide grooves 4, which are divided into two groups and are evenly opened at the top of the disassembly-free formwork 2. There are twelve blocks 11, one side of which is an inclined surface. There are six groups of slots 12, each with six, and twelve bolts 14, which are equally divided into two groups.

[0031] Specifically: through the setting of the through hole 13, the bolt 14 and the limit hole 15, the stability of the side panel 3 during use can be ensured. The purpose of setting six slide grooves 4 is to ensure the uniform placement of the fixing holes 6 to facilitate the uniform installation of the supporting steel bars 7. One side of the block 11 is designed with a slope, so that it can be guaranteed to move freely to one side without getting stuck.

[0032] The working principle of the present invention is as follows: when the distance between the two groups of non-disassembly formwork 2 becomes larger, the worker only needs to push the slider 5. Since one side of the block 11 is a slope, the slider 5 can move freely in one direction. In the process of pushing the slider 5, the block 11 will shrink toward the inside of the slider 5, squeezing the spring 10. When the slider 5 moves to the appropriate position, the spring 10 will rebound. The force generated by the rebound of the spring 10 pushes the slide 9 to move. The slide 9 drives the block 11 to move, so that the block 11 enters the inside of the slot 12. Then, the fixing hole 6 and the support steel bar 7 can be used normally, and there is no need to customize or temporarily process the support steel bar 7. This greatly improves the practicality of the non-disassembly formwork 2. The present invention has the advantages of no support and no disassembly formwork through the arrangement of the non-disassembly formwork 2 and the side panels 3, and solves the problem of the traditional concrete beam and slab construction method that requires a large amount of manpower for disassembly and assembly.
