[0002] Precast panels are a common form of floor slabs in early 20th century buildings, also known as "modules or panels for engineering". They are precast concrete parts produced and processed in prefabrication yards and transported directly to construction sites for installation, hence the name "precast panels". When producing precast panels, the molds need to be fixed on the platform according to the drawings, and steel bars are placed in the reinforcement holes of the molds. Concrete is poured into the molds. In the prior art, concrete is prone to overflow from the reinforcement holes during pouring. After the concrete in the mold is poured and formed, the overflowed slurry is difficult to clean up, and the steel bars are not firmly placed in the reinforcement holes. During the pouring process, the position of the steel bars is prone to shifting due to errors, collisions and other factors, affecting the quality of the finished product.
[0003] Therefore, it is necessary to provide a new prefabricated part mold fixing device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0027] See also Figures 1 to 8 The utility model provides a prefabricated part mold fixing device in an embodiment, which comprises a mold 1 and a mounting tube 2, and the mold 1 is provided with a reinforcement hole 1a for the reinforcement to pass through, and the outer plate wall of the mold 1 is provided with an annular mounting groove 1b coaxially arranged with the reinforcement hole 1a, and the mold 1 is provided with an open abutment column 11 between the reinforcement hole 1a and the annular mounting groove 1b.
[0028] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The mounting tube 2 is rotatably mounted in the annular mounting groove 1b, and a T-shaped ring rail 21 is fixedly mounted on the mounting end of the mounting tube 2. The T-shaped ring rail 21 is inserted into the T-shaped ring groove 1c provided in the mold 1 and is slidably connected to the T-shaped ring groove 1c. The mounting tube 2 is provided with an insertion opening 2a and an outer sliding cavity 2b. An elastic component 3 is provided in the mounting tube 2, and the elastic component 3 includes an elastic open annular airbag 31. The inner ring wall of one side of the elastic open annular airbag 31 is fixed. It is embedded with elastic pleated airbag columns 32 that are interconnected, and the end of the elastic pleated airbag column 32 is fixedly installed with an arc-shaped pressure block 33. The elastic open annular airbag 31 is embedded in the mounting tube 2, and the inner bag wall of the elastic open annular airbag 31 is fixedly connected to the inner tube wall of the mounting tube 2. The arc-shaped pressure block 33 is inserted into the outer sliding cavity 2b opened in the mounting tube 2 and abuts against the outer cylindrical surface of the open abutment column 11, and the outer tube wall of the mounting tube 2 is fixedly installed with a rotating open ring 22.
[0029] It should be noted that: initially, the installation tube 2 is rotated to the insertion opening 2a that is consistent with the reinforcement hole 1a. At this time, after the steel bar is placed at the reinforcement hole 1a position of the mold 1, the rotating open ring 22 is rotated so that the outer sliding cavity 2b on the rotating open ring 22 is rotated to the reinforcement hole 1a. At this time, the reinforcement hole 1a above the steel bar is blocked by the installation tube 2. At the same time, the arc-shaped pressing block 33 is rotated along the outer cylindrical surface of the open abutment column 11 until it is rotated to the opening of the open abutment column 11. The arc-shaped pressing block 33 corresponds to the opening, and then the pressing component 4 is used to drive the elastic open annular airbag 31 to be compressed. Since the elastic open annular airbag 31 is located in the installation tube 2 and the outer bag wall is pressed by the arc-shaped pressing plate 44, the gas on the inner wall of the elastic open annular airbag 31 flows into the elastic pleated airbag column 32 after compression and expands it. Therefore, the arc-shaped pressing block 33 can be firmly pressed against the upper circle wall of the steel bar (as shown in the attached figure). Figure 8 As shown), the expanded arc-shaped pressing block 33 can also seal the gap above the arc-shaped pressing block 33, which can well fix the position of the steel bar while preventing the slurry from leaking out, and avoid the hidden danger of the steel bar position deviation caused by collision affecting the quality of the cast finished product;
[0030] Among them, the elastic contraction force of the elastic pleated airbag column 32 is greater than the elastic contraction force of the elastic open annular airbag 31. Therefore, when the arc-shaped pressing plate 44 no longer presses the elastic open annular airbag 31, since the elastic contraction force of the elastic pleated airbag column 32 is greater than the elastic contraction force of the elastic open annular airbag 31, the gas in the elastic pleated airbag column 32 is caused to pleat and contract through the contraction force of the elastic pleated airbag column 32 itself, and the arc-shaped pressing block 33 slides back into the insertion port 2a.
[0031] In the embodiments of the present invention, please refer to Figure 1 , Figure 4 and Figure 7 A pressing component 4 for pressing the elastic open annular airbag 31 is provided on the rotating open ring 22, and the pressing component 4 includes a threaded mounting plate 41, and the threaded mounting plate 41 is fixedly mounted on the rotating open ring 22, and a threaded rod 42 with a threaded connection is inserted in the threaded through hole opened on the threaded mounting plate 41, and knobs 43 and arc-shaped pressing plates 44 are installed at both ends of the threaded rod 42, and the arc-shaped pressing plates 44 are rotatably mounted on the bottom of the threaded rod 42, and the arc-shaped pressing plates 44 are fixedly embedded in the outer bag wall of the elastic open annular airbag 31, and the knob 43 is fixedly mounted on the top of the threaded rod 42.
[0032] It should be noted that: rotating the knob 43 causes the threaded rod 42 to slide along the threaded mounting plate 41 , so that the arc-shaped pressing plate 44 presses the elastic open annular airbag 31 to compress it, and the operation is simple and convenient.
[0033] The working principle of the prefabricated part mold fixing device provided by the utility model is as follows:
[0034] Initially, the installation tube 2 is rotated until the insertion opening 2a is consistent with the rib hole 1a. At this time, after the steel bar is placed at the rib hole 1a of the mold 1, the rotating open ring 22 is rotated to make the outer sliding cavity 2b on the rotating open ring 22 rotate to the rib hole 1a. At this time, the rib hole 1a above the steel bar is blocked by the installation tube 2. At the same time, the arc-shaped pressing block 33 rotates along the outer cylindrical surface of the open abutment column 11 until it rotates to the opening of the open abutment column 11. The arc-shaped pressing block 33 corresponds to the opening, and then the pressing component 4 is used to drive the elastic open annular airbag 31 to be compressed. Specifically, the knob 43 is turned to make the threaded rod 42 slide along the threaded mounting plate 41. The arc-shaped pressing plate 44 presses the elastic open annular airbag 31 for compression, and the operation is simple and convenient. Since the elastic open annular airbag 31 is located in the mounting tube 2 and the outer airbag wall is pressed against the arc-shaped pressing plate 44, after the elastic open annular airbag 31 is compressed, the gas on its inner wall flows into the elastic pleated airbag column 32 and expands it. Therefore, the arc-shaped pressing block 33 can be firmly pressed against the upper circle wall of the steel bar, and the expanded arc-shaped pressing block 33 can also seal the gap above the arc-shaped pressing block 33, which can prevent the slurry from leaking out while fixing the position of the steel bar well, and avoid the hidden danger of the steel bar position displacement caused by collision affecting the quality of the cast finished product.
