[0020] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] The following is a further detailed description of the utility model in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows:

[0022] like Figures 1 to 3 As shown, the utility model provides a tunnel steel support construction platform, including a bottom platform 1 and two sets of steel support joint matching devices 2;

[0023] Among them, the upper surface of the bottom platform 1 is a horizontal plane, and the bottom platform 1 is arranged on the processing site as a welding platform; one group of steel support joint matching devices 2 are welded and fixed on the bottom platform 1, and another group of steel support joint matching devices 2 are detachably installed on the bottom platform 1. The detachably installed steel support joint matching devices 2 are adjusted according to the length of different unit components in the tunnel steel support support so that the distance between the two groups of steel support joint matching devices 2 adapts to the unit component length of the steel support support.

[0024] This technical solution may also include the following technical details to better achieve the technical effect: the bottom platform 1 is a steel plate.

[0025] The present technical scheme may also include the following technical details to better achieve the technical effect: the steel support joint matching device 2 includes: a first connecting steel plate 7, a first steel section 4, a second steel section 5 and a steel plate support pad 6; a plurality of connecting holes are opened on the first connecting steel plate 7, and a plurality of first connecting steel plates 7 are welded at intervals on the wing plate of the first steel section 4. The bottom inner side of the first steel section 4 is used to adjust its inclination angle through the steel plate support pad 6, and then the second steel section 5 is installed. After adjusting its inclination angle through the steel plate support pad 6 under the second steel section 5, the first steel section 4 and the second steel section 5 are connected as a whole through the fixed channel steel 9, so that the end of the single-piece rod of the unit component can be against the first connecting steel plate 7, and the end of the single-section rod 3 has a second connecting steel plate, the first connecting steel plate 7 and the second connecting steel plate are connected by bolts, and the inner side surface of the end of the single-piece rod of the unit component is supported by the second steel section 5. The steel support joint of the present application is used for a unit component with a certain curvature, so the first steel section 4 and the second steel section 5 need to be adjusted in angle to place the main steel section of the unit component, so as to facilitate the welding of the connecting steel bars 10 and the mesh steel bars after the main steel section is placed and fixed.

[0026] When installing the steel support joint matching device 2, first lay out and draw lines, put I-20 steel (i.e. the first steel 4) in place, use steel plate support 6 as a support pad on the inside, accurately adjust its angle and spot weld it, install I-12.6 steel (i.e. the second steel 5), and after adjusting the angle, connect the two groups of I-steels into a whole. After the first connecting steel plate 7 is in place, install the single-section rod 3 of the manufactured unit element, check whether the holes of the joint matching plate are completely aligned with the holes of the first connecting steel plate 7, and finally weld and fix the first connecting steel plate 7.

[0027] The present technical solution may also include the following technical details to better achieve the technical effect: the steel support joint matching device 2 also includes a stiffening plate 8, and a plurality of stiffening plates 8 are welded at intervals behind the first steel section 4. In the present embodiment, the stiffening plates 8 are arranged at intervals of 1 meter.

[0028] The present technical solution may also include the following technical details to better achieve the technical effect: wherein the fixed channel steel 9 of the steel support joint matching device 2 which is detachably connected to the bottom platform 1 is connected to the bottom platform 1 by bolts.

[0029] This technical solution may also include the following technical details to better achieve the technical effect: Figure 4 As shown, a limiting device is also included, which includes a gate-shaped steel base 11 and a plurality of upright columns 12;

[0030] The steel base is transversely arranged at the center position between the two sets of steel support joint matching devices 2, and the upright columns 12 are fixed to the surface of the gate-shaped steel base 11 in groups of two at intervals, and are used to limit the center part of the single rod 3 of the tunnel steel support. In this embodiment, the height of the gate-shaped steel base is set so that the bottom surface of the center part of the single rod can be placed on the top surface of the gate-shaped steel base. A upright column 12 is arranged on both sides of each single rod, and the upright column 12 is welded to the gate-shaped steel base 11, so as to limit the single rod 3. In addition, the height of the upright column 12 should be lower than half the height of the single rod 3 to avoid affecting the welding of the steel mesh.

[0031] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
