All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application discloses a pre-buried plate mounting device, which is shown in fig. 1, and comprises: a supporting structure 7 for bearing the embedded plate 8, two height-adjusting columns 4 for adjusting the height and a bracket 3 for supporting the embedded plate mounting equipment;
two height-adjusting columns 4 are fixedly arranged above the supporting structure 7 in parallel, each height-adjusting column 4 is provided with a limiting and adjusting device 1 for limiting and adjusting height, and the limiting and adjusting device 1 of each height-adjusting column 4 can be adjusted and fixed in a height adjusting range allowed by each height-adjusting column 4;
the bracket 3 is clamped below the limit adjusting device 1 through the limit adjusting devices 1 of the two height adjusting columns 4;
the bracket 3 is movably connected with each height-adjusting column 4 and each limit adjusting device 1.
Specifically, the supporting structure 7 of the embedded board installation device can form a sleeve opening, so that one end of the embedded board 8 can enter and is supported by the supporting structure 7, two independent embedded board installation devices are required to be used cooperatively during installation to hoist the embedded board 8, and the embedded board 8 is hoisted, as shown in fig. 2, by placing two symmetrical ends of the embedded board 8 on the supporting structure 7 of the two embedded board installation devices respectively, the two embedded board installation devices can hoist the embedded board 8.
Specifically, after bearing the embedded board 8 through the supporting structure 7, the embedded board installation device can be lifted by taking the bracket 3 as a supporting point in a manual mode or a crane mode or the like, at the moment, the bottom of the height-adjusting column 4 is fixedly connected with the supporting structure 7, the limiting device on the height-adjusting column 4 clamps the main bracket 3, the height-adjusting column 4 plays a role of connecting the bracket 3 with the supporting structure 7, the lifting device can lift the whole embedded installation device and the embedded board 8 therein through the bracket 3, two embedded board installation devices bearing the same embedded board 8 are lifted in place together through the lifting device, the brackets 3 of the two embedded board installation devices are placed on the supporting structure 7 around a construction site, for example, a template preset beside the bracket is used, and the embedded board 8 is suspended by the template supporting bracket 3.
Specifically, after the embedded plate 8 is hoisted in place, see fig. 3, the brackets 3 on the two embedded plate installation devices are supported above the installation positions by means of the templates beside, and at the moment, the height of the embedded plate 8 can be finely adjusted by adjusting the limit adjusting devices 1 on the four height-adjusting columns 4 on the two embedded plate installation devices, and the height of the embedded plate 8 on the installation positions can be adjusted by adjusting the heights of the four limit adjusting devices 1 on the four height-adjusting columns 4, so that whether the embedded plate 8 is adjusted to the correct height can be determined by the corresponding height measuring devices.
Specifically, the limit adjusting device 1 may have a latch, a thread, or other structures, and be matched with a limit structure on the height-adjusting column 4, such as a thread, a slot, or other limit structures, to adjust the height, and to fix the height-adjusting column 4 to achieve the limit.
Specifically, the hole 11 that can allow the height-adjusting column 4 to pass is reserved on the support 3 in advance, the support 3 is sleeved on two height-adjusting columns 4, then the corresponding limit adjusting device 1 is installed on the two height-adjusting columns 4, and accordingly installation is achieved, the reserved hole 11 on the support 3 can only allow the height-adjusting column 4 to pass, after the limit adjusting device 1 is additionally installed, the width of the limit adjusting device 1 exceeds the reserved hole 11 on the support 3, therefore the support 3 cannot move upwards from below the limit adjusting device 1, and therefore the height of the embedded plate 8 on the supporting structure 7 below the height-adjusting column 4 from the support 3 can be adjusted through adjusting the height of the limit adjusting device 1 on the height-adjusting column 4, and accordingly height adjustment is achieved.
Specifically, through dragging support 3 or utilizing the hole 11 that reserves on the support 3, also can make pre-buried board 8 remove in the direction of speaking, realize the fine setting, ensure that pre-buried board 8 is accurate to be installed at appointed place.

The embodiment of the application discloses a specific embedded plate mounting device, and compared with the previous embodiment, the technical scheme of the embodiment is further described and optimized.
Specifically, the support structure 7 on the installation apparatus of the pre-buried plate for bearing the pre-buried plate 8 may be an integral structure, for example, as shown in fig. 4 or fig. 5, but because the pre-buried plate 8 has various sizes, for convenience in manufacturing the support structure 7 corresponding to the size of the pre-buried plate 8, the support structure 7 may include 3 parts, which are the first support structure 2 and the second support structure 5 for supporting the pre-buried plate 8 and the transverse fixing structure 6 for fixedly connecting the first support structure 2 and the second support structure 5, respectively, as shown in fig. 1;
the first support structure 2 and the second support structure 5 are fixedly connected through a transverse fixing structure 6 to form a sleeve opening capable of bearing the embedded plate 8;
two height-adjusting posts 4 are fixedly arranged on the transverse fixing structure 6.
Specifically, as shown in fig. 1, the first support structure 2 and the second support structure 5 may be L-shaped steel, and the first support structure 2 and the second support structure 5 may also be concave-shaped steel, so long as the transverse fixing structure 6 is fixed above the first support structure 2 and the second support structure 5.
Further, referring to fig. 6, in order to increase applicability of the embedded board mounting apparatus, the transverse fixing structure 6 may be a structure with a telescopic function, such as a telescopic rod, and the distance between the first support structure 2 and the second support structure 5 may be adjusted by telescopic operation, so as to implement the embedded board 8 with various widths adapted, and at this time, the two height-adjusting posts 4 may be mounted in an area where the telescopic rod is not moved, so that the height-adjusting function is not affected.
Specifically, referring to fig. 7, for convenience in assembly at a construction site, the bracket 3 is formed by splicing two steel pipes and a welding member 10 having a fixing function, and a hole 11 allowing two height-adjusting columns 4 to pass through and having a width larger than the diameter of the two height-adjusting columns 4 and smaller than the diameter of the two limit adjusting devices 1 is reserved between the two steel pipes. Meanwhile, the limit adjusting device 1 can be a nut, threads can be arranged on each heightening column 4, the limit adjusting device 1 can be a hexagon nut, the height can be adjusted by screwing on the heightening column 4, in order to better resist the support 3, the support 3 can be ensured to be stably resisted below by the limit adjusting device 1, the limit adjusting device 1 can be a nut with a boss 12 arranged at the bottom, and the radius of the nut is increased by the boss 12, as shown in fig. 1.
