[0006] In view of the above problems in the prior art, the utility model aims to provide a beam hole steel plate leveling and demoulding device for a beam and slab prefabricated pedestal, which solves the existing problems.

[0007] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0008] A beam-slab prefabricated pedestal steel plate leveling and demoulding device is provided, the leveling and demoulding device comprising a support seat, a leveling steel plate arranged at an open end of the support seat, and a spirit level fixedly mounted on the leveling steel plate.

[0009] In order to solve the problem of prefabricated parts leveling and demoulding, four evenly distributed jacks are fixedly installed in the support seat, and the telescopic ends of the four jacks are fixedly installed with top plates. The leveling steel plate is symmetrically provided with four groups of mounting grooves corresponding to the jacks, and a connecting groove connected to the mounting groove and corresponding to the telescopic ends of the jacks is provided between two of the mounting grooves. The telescopic ends of the jacks are covered with support plates, and the support plates are slidably connected to the telescopic ends of the jacks.

By setting the top plate and the support plate, the leveling steel plate can be leveled, which is convenient for making prefabricated parts. At the same time, by rotating the threaded sleeve, the distance between the support plate and the top plate can be adjusted, thereby realizing the demoulding of the prefabricated parts, and the operation is simpler and more convenient.

For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0021] Example 1

[0022] The utility model provides a beam and slab prefabricated pedestal steel plate leveling and demoulding device. Figure 1-3 As shown, the leveling and demoulding device comprises a support seat 1, a leveling steel plate 2 arranged at the open end of the support seat 1, and a level 24 fixedly mounted on the leveling steel plate 2;

[0023] Four evenly distributed jacks 3 are fixedly installed in the support seat 1, and the telescopic ends of the four jacks 3 are fixedly installed with top plates 4. Four groups of mounting grooves 21 corresponding to the jacks 3 are symmetrically arranged on the leveling steel plate 2, and a connecting groove 22 connected with the mounting grooves 21 and corresponding to the telescopic ends of the jacks 3 is arranged between two of the mounting grooves 21. The telescopic ends of the jacks 3 are covered with support plates 31, and the support plates 31 are slidably connected to the telescopic ends of the jacks 3.

[0024] When in use, the support seat 1 can be placed on the pedestal, and then the four jacks 3 can be telescopically adjusted to adjust the four corners of the leveling steel plate 2, so that the flatness of the leveling steel plate 2 can be observed according to the spirit level 24. After the leveling steel plate 2 is leveled, the prefabricated parts can be made on the leveling steel plate 2.

[0025] Furthermore, a limit strip 11 is fixedly installed at the open end of the support seat 1, and a fixing strip 12 is fixedly installed inside the support seat 1; when in use, the jack 3 can be shortened first, so that the leveling steel plate 2 can contact with the fixing strip 12 to be supported, and then the support plate 31 is operated to separate the support plate 31 from the installation groove 21, and the demolding operation can be started.

[0026] Furthermore, a limiting groove 23 corresponding to the limiting strip 11 is provided on the leveling steel plate 2; during demolding, the jack 3 can lift the leveling steel plate 2, and when it is lifted to the position corresponding to the leveling steel plate 2 and the limiting groove 23, the leveling steel plate 2 can be limited under the action of the limiting groove 23. At this time, the leveling steel plate 2 can be limited, and the jack 3 continues to drive the prefabricated part to move through the top plate 4, thereby realizing the separation of the prefabricated part and the leveling steel plate 2 and achieving demolding.

[0027] Specifically, the top plate 4 and the support plate 31 have the same size and are compatible with the mounting groove 21; the top plate 4, the support plate 31 and the mounting groove 21 are compatible, ensuring that the jack 3 can drive a corner of the leveling steel plate 2 to move, thereby facilitating leveling.

[0028] Furthermore, the support base 1 is symmetrically provided with a plurality of beam-lifting holes 13 distributed in a linear array, and the support base 1 is symmetrically provided with two groups of operating holes 14; when in use, the completed prefabricated parts can be hoisted through the beam-lifting holes 13, and the jack 3 can be operated through the operating holes 14, which makes it more convenient to use.

[0029] Example 2

[0030] Different from the first embodiment, the telescopic end of the jack 3 is threadedly connected with a threaded sleeve 32 , and the threaded sleeve 32 is rotatably connected to the support plate 31 .

[0031] When the leveling steel plate 2 is being leveled, the support plate 31 is located inside the mounting groove 21, and a certain gap is left between the top plate 4, the support plate 31 and the mounting groove 21, so that the leveling steel plate 2 can be leveled. When the prefabricated part is demoulded after being made, the jack 3 can be lowered first so that the leveling steel plate 2 contacts the fixing bar 12. At this time, the threaded sleeve 32 is rotated through the operating hole 14 to separate the support plate 31 from the mounting groove 21. The jack 3 can be extended again to realize the demoulding operation of the leveling steel plate 2.
