[0021] The slider 2 6 can slide up and down through the sliding action of the slider 3 11 and the slide groove 3 10. When the slider 2 6 needs to be installed, the slider 2 6 is pushed upward to make the telescopic rod 7 and the spring 8 shrink upward, so that the position of the slider 2 6 is pushed upward, and then aligned with the slide groove 2 5, and the slider 2 6 is released so that the spring 8 provides elastic force to push the slider 2 6 into the inside of the slide groove 2 5, thereby facilitating the installation effect.
[0022] Among them, a slide groove 4 13 is opened at the bottom of the wooden board 1, and a slider 4 12 is slidably connected inside the slide groove 4 13. The slider 4 12 is fixedly connected to the connecting block 9, and the slider 4 12 is located at the bottom end of the connecting block 9.
[0023] The slide groove four 13 is located directly below the slide groove two 5, and the slider four 12 is located directly below the slider two 6. When the connecting block 9 needs to be installed, the slider four 12 needs to be installed to the inside of the slide groove four 13 through a sliding connection first, so as to facilitate the positioning of the connecting block 9.
[0024] Among them, the outer side of the connecting block 9 is provided with a first pair of tension steel bars 14 and a second pair of tension steel bars 17. The two ends of the first pair of tension steel bars 14 are slidably connected with mounting sleeves 16. The mounting sleeves 16 and the second pair of tension steel bars 17 are fixedly connected. At the same time, the extension surfaces of the first pair of tension steel bars 14 and the second pair of tension steel bars 17 close to the mounting sleeves 16 are vertical.
[0025] The first pair of tensioning steel bars 14 and the second pair of tensioning steel bars 17 are both fitted with the connecting block 9, so that the connecting block 9 and the wooden board 1 are limited in position. When pouring, after the concrete expands, the wooden board 1 is limited and fixed by the first pair of tensioning steel bars 14 and the second pair of tensioning steel bars 17, so it will not be displaced or stretched.
[0026] Among them, a positioning hole 15 is opened inside the first tensioning steel bar 14, a limiting pin 18 is inserted inside the positioning hole 15, a collecting groove 19 is opened inside the limiting pin 18, there are multiple positioning holes 15, and the multiple positioning holes 15 are all located inside the wooden board 1.
[0027] The limiting pin 18 is fitted with the installation sleeve 16, and the limiting pin 18 is wide at the top and narrow at the bottom. When the installation sleeve 16 is connected to the outside of the first tensioning steel bar 14, the installation sleeve 16 will be limited by the limiting pin 18 so that it will not be displaced, thereby achieving the effect of limiting and fixing.
[0028] Among them, there are four wooden boards 1, which are perpendicular to each other. There are multiple slide grooves 2 and sliders 3. The multiple slide grooves 2 are respectively located at both ends of the four wooden boards 1, and two slide grooves 2 are opened inside each wooden board 1. There are four sealing blocks 4, which are respectively located at the intersections of the four wooden boards 1.
[0029] The four sealing blocks 4 are installed to the positions where the four wooden boards 1 contact each other by sliding through multiple sliders 3 and multiple slide grooves 2, so that the four wooden boards 1 are fixed and the gaps at their intersections are sealed to prevent concrete from seeping out during pouring.
[0030] Among them, there are multiple connecting blocks 9, and the multiple connecting blocks 9 are distributed around the outer sides of the four wooden boards 1. At the same time, the multiple connecting blocks 9 are fixed to the wooden boards 1 through the sliding action of the slider 2 6 and the slide groove 2 5 and the sliding action of the slider 4 12 and the slide groove 4 13.
[0031] The main function of the plurality of connecting blocks 9 is to increase the stress-bearing range of the wooden board 1 , to prevent the wooden board 1 from being stretched or directly broken when subjected to stress, and to increase the overall firmness.
[0032] The working principle and use process of this utility model:
[0033] First, the connecting block 9 is installed to the outside of the wooden board 1 through the sliding action of the slider 4 12 and the slide groove 4 13, and the slider 2 6 is pushed upward to shrink the telescopic rod 7 and the spring 8, and the height value of the slider 2 6 exceeds the height value of the slide groove 2 5, and then the slider 2 6 is aligned with the slide groove 2 5, and the upper and lower ends of the connecting block 9 are fixed by the sliding action of the slider 2 6 and the slide groove 2 5;
[0034] Secondly, the sealing block 4 is connected to the wooden board 1 through the sliding action of the slider 1 and the slide groove 1. At the same time, the sealing block 4 will seal the intersection between the wooden boards 1 to prevent the concrete from penetrating during pouring.
[0035] At this time, the installation sleeve 16 is slidably sleeved onto the outer side of the first tension steel bar 14, so that the second tension steel bar 17 and the first tension steel bar 14 surround the outer side of the wooden board 1 and are in contact with the outer side of the connecting block 9. Finally, the limit pin 18 is inserted into the interior of the positioning hole 15, and the limit pin 18 is fitted with the installation sleeve 16, so as to achieve the effect of fixing and limiting the installation sleeve 16.
[0036] Finally, concrete is poured into the interior of the wooden board 1 to complete the overall casting. At the same time, since the outer side of the wooden board 1 is subjected to increased stress by the connecting block 9 and is limited by the second pair of tensile steel bars 17 and the first pair of tensile steel bars 14, when the concrete solidifies and expands inside, the wooden board 1 will not break or stretch, thereby increasing the overall firmness.
