Specifically, during installation, the positioning rod and the positioning slot are connected in the vertical direction or the horizontal direction according to the angle of the steel bar. When connecting in the vertical direction, the connection block needs to be installed and fixed after the positioning rod and the positioning slot are connected. Before installation and fixation, it is necessary to use external force to move the support plate to compress the spring. When the connection block and the positioning rod are firmly fixed, the external force is removed, so that the support plate is connected to the upper and lower parts of the middle template under the elastic force of the spring. When the bolt is in contact with the guide rails, the springs are engaged, and the guide rails are engaged with the guide rails, which are in contact with the guide rails on the upper and lower surfaces of the middle template.

[0028] The utility model provides a separate prefabricated beam and slab side formwork structure, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes an upper template 1, a middle template 2, a lower template 3 and multiple back ribs 4, wherein the upper template 1, the middle template 2 and the lower template 3 all have a certain thickness, and the upper template 1, the middle template 2 and the lower template 3 are spliced in sequence along the vertical direction, the middle part of the back rib 4 is fixedly connected to the back of the middle template 2, the upper part is movably connected to the upper template 1 through a connecting piece, and the lower part is movably connected to the lower template 3 through a connecting piece, and multiple back ribs 4 are arranged at intervals along the length direction of the middle template 2, and the upper template 1 and the lower template 3 are both provided with comb teeth 5 for placing positioning steel bars, and the comb teeth 5 are connected to the middle template 2.

[0029] In this embodiment, the upper formwork 1, the middle formwork 2, the lower formwork 3, the multiple back ribs 4 and the comb teeth 5 are connected to the middle formwork 2, which can facilitate the demolding of the side formwork; the utility model divides the side formwork into three parts, which can solve the problem that when the existing side formwork uses a whole plate, the formwork cannot be removed after tying the steel bars and pouring the concrete.

[0030] In the present invention, preferably, Figure 1 、 Figure 2 and Figure 3 As shown, the connecting part includes a connecting rod 6 and a bolt 7. A through hole is provided on the back rib 4. One end of the connecting rod 6 is fixedly connected to the upper template 1 or the lower template 3, and the other end is fixedly connected to the through hole by a bolt 7. In order to reduce the installation accuracy, the size of the through hole can be appropriately increased, and corresponding gaskets can be provided for installation.

[0031] In this embodiment, by providing the connecting rod 6, the bolt 7 and the through hole, the upper template 1 or the lower template 3 can be easily assembled and disassembled, thereby improving efficiency.

[0032] In the present invention, preferably, Figure 1 and Figure 2 As shown, the front side of the middle template 2 is a flat plate, and the upper and lower sides of the flat plate are respectively fitted with the bottom side of the upper template 1 and the top side of the lower template 3 .

[0033] In this embodiment, by setting the front side of the middle template 2 as a flat plate, the opening size of the comb teeth 5 can be reduced, effectively avoiding the leakage of concrete during pouring.

[0034] In the present invention, preferably, Figure 1 、 Figure 3 and Figure 4 As shown, the upper template 1 and the lower template 3 are both provided with positioning rods 8 along the vertical direction, and the upper and lower surfaces of the middle template 2 are both provided with positioning grooves 9, the length direction of the positioning groove 9 is consistent with the length direction of the connecting rod 6, and the end of the positioning groove 9 close to the back rib 4 is connected to the back of the middle template 2. When the positioning rod 8 is matched with the positioning groove 9, the ends of the upper template 1, the middle template 2 and the lower template 3 are flush; the positioning rods 8 include multiple ones, and the multiple positioning rods 8 are arranged at intervals along the length direction of the upper template 1 or the lower template 3.

[0035] In this embodiment, through the setting of the positioning rod 8 and the positioning groove 9, the positioning of the upper template 1 and the lower template 3 can be facilitated, and the installation efficiency is improved. Combined with the length direction of the positioning groove 9 being consistent with the length direction of the connecting rod 6, the positioning groove 9 is connected to the back of the middle template 2 at one end close to the back rib 4, which can facilitate the adjustment of the upper template 1 and the lower template 3 in the direction perpendicular to their surfaces, reducing the difficulty of installation. At the same time, the positioning rod 8 and the positioning groove 9 can be selected to cooperate in the vertical direction or the horizontal direction according to actual conditions; combined with the setting of multiple positioning rods 8, the positioning accuracy can be improved.

[0036] In the present invention, preferably, Figure 3 and Figure 4 As shown, an auxiliary connecting assembly is installed on the positioning rod 8, and the auxiliary connecting assembly includes a connecting block 10, a support plate 11 and a spring 12. The connecting block 10 is detachably installed on the end of the positioning rod 8 away from the upper template 1 or the lower template 3, and the support plate 11 is slidably sleeved on the positioning rod 8. The spring 12 is sleeved on the positioning rod 8, and the two ends of the spring 12 are respectively fixedly connected to the connecting block 10 and the support plate 11. When the positioning rod 8 is matched with the positioning groove 9, the support plate 11 abuts against the upper and lower surfaces of the middle template 2 under the elastic force of the spring 12.

[0037] In this embodiment, by setting up the auxiliary connecting assembly including the connecting block 10, the support plate 11 and the spring 12, the free movement of the positioning rod 8 and the positioning groove 9 after cooperation can be avoided, thereby further improving the positioning accuracy. At the same time, the upper template 1 or the lower template 3 can be temporarily fixed to the middle template 2, which facilitates the connection and fixation of the bolt 7 to the through hole. Specifically, during installation, the positioning rod 8 and the positioning groove 9 are connected in the vertical direction or the horizontal direction according to the angle of the steel bar. When connected in the vertical direction, the connecting block 10 needs to wait until the positioning rod 8 and the positioning groove 9 are connected before installation and fixation. Before installation and fixation, it is necessary to use external force to move the support plate 11 to compress the spring 12. When the connecting block 10 is firmly fixed to the positioning rod 8, the external force is removed, so that the support plate 11 is connected to the middle template 2 under the elastic force of the spring 12. The upper and lower surfaces can be abutted. When connecting in the horizontal direction, it is necessary to first install and fix the connecting block 10 and the positioning rod 8, and then connect the positioning rod 8 and the positioning slot 9. Before connecting, it is necessary to use external force to pull down or pull up the support plate 11 to compress the spring 12. When installing the upper template 1, pull down is used, and when installing the lower template 3, pull up is used, so as to leave a space of sufficient length for the positioning rod 8 and the positioning slot 9 to cooperate. When the positioning rod 8 and the positioning slot 9 are fully matched, remove the external force, so that the support plate 11 can be abutted against the upper and lower surfaces of the middle template 2 under the elastic force of the spring 12. In this process, the elastic force of the spring 12 can ensure that the upper template 1 or the lower template 3 is tightly fitted with the middle template 2, so that when the bolt 7 is connected, there is no need for additional support and fixation, and the threaded connection can be conveniently and quickly performed.
