[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment: an assembled non-disassembly steel bar truss formwork, including a bottom formwork 1, the inner wall of the bottom formwork 1 is provided with a positioning mechanism, the inner wall of the bottom formwork 1 is fixedly connected with a guide tube 4, the guide tube 4 allows the L frame 3 to move laterally, and the movement trajectory will not be offset, the top of the bottom formwork 1 is in contact with a steel truss 5, the steel truss 5 can provide structural support, share loads, provide rigid support and other functions, and the outer wall of the steel truss 5 is provided with a card slot 6.

[0027] Reference Figure 1 and Figure 4 The right end side wall of the bottom template 1 is fixedly connected with a plug plate 7, and the right end inner wall of the bottom template 1 is elastically connected with a limit block 9 through a positioning spring 8. The limit block 9 is an inclined surface. When the inclined surface is squeezed, the limit block 9 will slide along the inner wall of the inner wall bottom template 1. The bottom end of the limit block 9 is fixedly connected with a fixed block 10, and the fixed block 10 is used to move the limit block 9 to achieve the effect of releasing the limit. The right end inner wall of the bottom template 1 is fixedly connected with one end of the positioning spring 8. When the limit block 9 moves to the right, the positioning spring 8 will be compressed. When resetting, the elastic force of the positioning spring 8 is used to reset the limit block 9. The other end of the positioning spring 8 is fixedly connected to the right end of the limit block 9, and the limit block 9 is slidably connected to the inner wall of the bottom template 1. The limit block 9 is plugged into the side wall of the plug plate 7. The side wall of the plug plate 7 is provided with a notch, which can allow the notch of the plug plate 7 to be plugged into the limit block 9 to connect the two groups of bottom templates 1, and the plug plate 7 is plugged into the left end side wall of the bottom template 1.

[0028] Reference Figure 1-Figure 3 The positioning mechanism includes an L frame 3, which is slidably connected to the inner wall of the bottom template 1. The left end of the L frame 3 is fixedly connected to one end of the return spring 2. When the L frame 3 moves to the left, the return spring 2 is compressed. When resetting, the elastic force of the return spring 2 is used to bring the L frame 3 back to the original position. This position relationship is based on Figure 2 As shown, the other end of the return spring 2 is fixedly connected to the inner wall of the left end of the bottom template 1, the L frame 3 is slidably connected to the outer wall of the guide tube 4, and the L frame 3 is plugged into the inner wall of the slot 6.

[0029] Working principle: First, when the steel truss 5 and the bottom template 1 need to be separated and disassembled, just move the L frame 3 to the left and compress the reset spring 2 to separate the L frame 3 and the slot 6 on the steel truss 5, and then take the steel truss 5 out from the top of the bottom template 1. When it needs to be installed, just place the steel truss 5 on the bottom template 1, let the notches of the L frame 3 and the slot 6 correspond, and finally release the L frame 3 and use the reverse elastic force of the reset spring 2 to reset the L frame 3, so that the L frame 3 and the slot 6 on the steel truss 5 are plugged in, completing the preliminary positioning and installation of the entire steel truss 5, and finally fasten the steel truss 5 and the bottom template 1 by bolts to facilitate the accuracy and consistency of subsequent concrete pouring, which helps to improve the quality and reliability of the building.

[0030] When multiple groups of bottom templates 1 need to be spliced ​​and cast, it is only necessary to insert the plug plate 7 into the groove of the left side wall of the bottom template 1 so that the right end of the plug plate 7 squeezes the inclined surface of the limit block 9, so that the limit block 9 moves to the right and compresses the positioning spring 8. When the groove on the side wall of the plug plate 7 coincides with the limit block 9, the elastic force of the positioning spring 8 is used to connect the limit block 9 with the side wall groove of the plug plate 7 to complete the one-way limit. When the limit needs to be released, it is only necessary to separate the limit block 9 and the plug plate 7 by moving the fixed block 10, so that the plug plate 7 can be moved out of the groove of the left side wall of the bottom template 1, and the splicing of multiple groups of bottom templates 1 can be released.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
