Therefore, the elastic mounting structure is not limited herein.

The precast beam bottom die support disclosed by the embodiment is specifically used as follows:

in order to keep the inclination angle of the panel 2 consistent with the construction site inclination, it is necessary to measure the construction site inclination before construction. And then the screw connection positions of the four adjusting screws 7 below the panel 2 and the corresponding sleeves 9 are adjusted according to the gradient of the construction site so as to change the inclination angle of the panel 2. In the specific process of adjusting each adjusting screw 7, due to the existence of the bracket 9 and the rotating shaft 5 arranged below the panel 2, the panel 2 can only rotate around the rotating shaft 5, that is, only two adjusting screws 7 on one side of the rotating shaft 5 can be lifted, and simultaneously two adjusting screws 7 on the other side of the rotating shaft 5 are lowered, so that the inclination angle of the panel 2 can be adjusted. In other words, in the specific adjusting process, it is necessary to adjust the two adjusting screws 7 on one side of the rotating shaft 5 at the same time, and adjust the two adjusting screws 7 on the other side of the rotating shaft 5 at the same time, so that the edge of the panel 2 on one side of the rotating shaft 5 is raised, and the edge of the panel 2 on the other side of the rotating shaft 5 is lowered, thereby adjusting the inclination angle of the panel 2. When the inclination angle of the panel 2 is consistent with the gradient of a construction site, the precast beam 19 required by construction can be directly erected on the panel 2 to complete the subsequent construction process. It is worth noting that the adjusting method of the screwing position depends on a specific screwing structure between the adjusting screw 7 and the sleeve 9, if the sleeve 9 is screwed with the adjusting screw 7 through the adjusting nut 10, the screwing position can be changed only by rotating the adjusting nut 10 on the sleeve 9, and further the length of the adjusting screw 7 extending into the sleeve 9 is controlled, so as to complete the adjustment of the top position of the panel 2; if sleeve 9 directly sets up the internal thread in the inboard face to realize the spiro union with adjusting screw 7, then need rotate adjusting screw 7, make adjusting screw 7's circular joint 8 take place to rotate in locator 6's indent arc structure, and then change adjusting screw 7 and sleeve 9's spiro union position, in order to realize stretching into the control of sleeve 9 interior length to adjusting screw 7. The specific adjustment manner of the screwing position depends on the screwing structure of the sleeve 9 and the adjusting screw 7, and a detailed description thereof is omitted.

The precast beam bottom die support disclosed in this embodiment realizes the adjustment of the inclination angle of the panel 2 by arranging the positioner 6, the adjusting screw 7 and the sleeve 9 between the panel 2 and the base 1, so that the precast beam bottom die support can be applied to the bridge construction with various slopes. Moreover, the whole adjusting process of the inclination angle of the panel 2 only needs to rotate the adjusting nut 10 or the adjusting screw 7, the screwing position of each adjusting screw 7 and the sleeve 9 can be changed, the adjustment of the inclination angle of the panel 2 is realized, the operation process is simple, the adjustment can be completed in a short time, and the adjusting efficiency is high. Most importantly, the whole adjusting process does not need to be subjected to the processes of dismantling and re-welding, so that the material waste and the investment of constructors are greatly reduced, the construction cost is favorably reduced, and the economic benefit of a construction unit is improved.
