Detailed implementation manners
[0023] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
[0025] The following combines Figures 1 to 5 to specifically illustrate an adjustable magnetic adsorption fixture for prestressed composite slab production according to an embodiment of the present invention.
[0026] Such as Figures 1 to 5As shown in the figure, an adjustable magnetic adsorption fixture for the production of prestressed composite slabs according to an embodiment of the present utility model includes: an upper flat plate structure 102, a lower flat plate structure 104, an adjustment bolt 106, an adjustment nut 108, a magnetic adsorption fixture 110, etc. The upper flat plate structure 102 includes an upper flat plate 1022 and two oppositely arranged first side support plates 1024 integrally formed with the upper flat plate 1022, and a connection through hole 1026 is provided on the upper flat plate 1022. The lower flat plate structure 104 includes a lower flat plate 1042 and two oppositely arranged second side support plates 1044 integrally formed with the lower flat plate 1042. The second side support plates 1044 are flush with the bottom surfaces of the first side support plates 1024, and the formed two end portions can be more evenly pressed on two adjacent templates, and the force is relatively balanced. An adjustment through hole 1046 is provided on the lower flat plate 1042, and the adjustment through hole 1046 corresponds to the connection through hole 1026, so that the fixed position of the lower flat plate structure 104 and the upper flat plate structure 102 can be adjusted, and further the length adjustment of the entire magnetic adsorption fixture can be realized. The adjustment bolt 106 sequentially passes through the connection through hole 1026 and the adjustment through hole 1046 from the top surface of the upper flat plate 1022, and two adjustment nuts 108 are sleeved on the adjustment bolt 106, one is above the top surface of the upper flat plate 1022, and the other is below the bottom surface of the lower flat plate 1042, so that the tightening and fixing and the loosening and movement between the upper flat plate structure 102 and the lower flat plate structure 104 can be realized. The magnetic adsorption fixture 110 is connected to the bottom end of the adjustment bolt 106. By cooperating with the adjustment nut 108 and the adjustment bolt 106, the height of the magnetic adsorption fixture 110 can be adjusted. Generally, its bottom surface is flush with the bottom surfaces of the first side support plates 1024 and the second side support plates 1044, which can not only provide appropriate pressure for two adjacent cross molds to ensure product quality, but also facilitate the disassembly of the magnetic adsorption fixture. The adjustable magnetic adsorption fixture for the production of prestressed composite slabs can press on two adjacent cross molds through the end portions of the side support plates, and the magnetic adsorption fixture 110 adsorbs on the iron mold table to realize the support and position fixation of the cross molds, and basically no mold running phenomenon will occur, ensuring the production quality of prestressed composite slabs. The relative position of the lower flat plate structure 104 and the upper flat plate structure 102 is adjustable, so that it can adapt to different cross mold spacings.
[0027] Further, as Figure 3 shown, the magnetic adsorption fixture 110 is annular and is threadedly connected with the adjustment nut 108, which can not only ensure the pressure on two adjacent cross molds, but also facilitate disassembly.
[0028] Further, as Figure 5As shown in the figure, the adjustment through hole 1046 is an arc-shaped long hole. The width of the arc-shaped long hole is smaller than the outer diameter of the adjusting nut 108, and the length of the arc-shaped long hole is not greater than half of the length of the lower flat plate 1042. Thus, the relative position between the lower flat plate structure 104 and the upper flat plate structure 102 can be adjusted, and thus, it can adapt to different transverse mode spacings. The minimum length of the length adjustment is the length of the first side support plate 1024, and the maximum length is less than the length of the first side support plate 1024 plus half of the length of the second side support plate 1044. In this way, the magnetic adsorption fixing part 110 can be used to achieve relatively firm adsorption and fixation, ensuring the pressing and fixing effect of the end of the side support plate on the transverse mode.
[0029] Furthermore, the length adjustment range is 8 cm - 12 cm.
[0030] Furthermore, the magnetic adsorption fixing part 110 corresponds to the central area of the upper flat plate 1022, and when in use, its bottom surface is flush with the bottom surfaces of the first side support plate 1024 and the second side support plate 1044. It can not only provide appropriate pressure for two adjacent transverse modes to ensure product quality, but also facilitate the disassembly of the magnetic adsorption fixator.
[0031] The working process of an adjustable magnetic adsorption fixator for prestressed composite slab production proposed by the present utility model is as follows: [[ID=X]]
[0032] Place the iron mold table, side mold, steel bars, and multiple transverse modes inside the side mold frame; adjust the length of the adjustable magnetic adsorption fixator for prestressed composite slab production according to the length of the gap required between adjacent casting plates; the side support plates of the adjustable magnetic adsorption fixator for prestressed composite slab production are placed through the gaps of the steel bars, and the ends of the side support plates are pressed on two transverse modes (the transverse mode is a long strip plate with an L-shaped cross-section), the ends of the side support plates are pressed on the flat plates of the two transverse modes, and the magnetic adsorption fixing part 110 is adsorbed on the iron mold table, thereby fixing and limiting the two transverse modes, ensuring that there is no mold running during the casting of the corresponding plates.
