[0032] The housing construction prefabricated beam mold can be placed on the corresponding platform in advance before the concrete pouring of the prefabricated beam, the width of the first pouring cavity 2 or the second pouring cavity 3 to be poured at present is adjusted in advance according to the width design requirement of the prefabricated beam, the width of the first pouring cavity 2 and the second pouring cavity 3 can be adjusted by screwing the corresponding locking clamping parts, one is enlarged and the other is reduced, finally, the state of adjustment and locking is reached, then the internal bundled steel bars are prevented and the concrete is poured into the corresponding pouring cavity and vibrated as required, and the concrete is completely solidified into the prefabricated beam after waiting.

[0033] In any of the above schemes, preferably, the sliding frame includes two through openings 5 respectively arranged on the corresponding end portion side walls of the middle partition plate 4, end portion sliding baffle plates 6 perpendicular to the middle partition plate 4 are respectively slidably inserted into the two through openings 5, the two end portion sliding baffle plates 6 are integrally welded and fixedly connected through a connecting side plate 7 perpendicular thereto, the bottom of the two end portion sliding baffle plates 6 and the bottom of the connecting side plate 7 are both matched and tightly abutted with the bottom of the first pouring cavity 2, and the right ends of the two end portion sliding baffle plates 6 are fixedly welded on the left side wall of the locking clamping part.

[0034] The whole sliding frame is formed into a U-shaped sliding frame by welding two end portion sliding baffle plates 6 and a connecting side plate 7, and the width size of the first pouring cavity 2 and the second pouring cavity 3 can be adjusted simultaneously in the sliding process, so that one of the pouring cavities is adjusted to the appropriate size as required, and the locking part is directly adjusted by screwing the locking clamping part to achieve rapid adjustment and timely locking.

[0035] In the sliding process, the through opening 5 and the end portion sliding baffle plate 6 are slidably matched to realize stable constraint and positioning and ensure the smoothness of sliding.

[0036] In any of the above schemes, preferably, the locking clamping part includes an inverted U-shaped plate frame 8 clamped on both sides of the right side wall of the second pouring cavity 3, the bottom of the left vertical section of the inverted U-shaped plate frame 8 abuts against the bottom of the second pouring cavity 3, the right vertical section of the inverted U-shaped plate frame 8 is arranged outside the second pouring cavity 3, a connecting pipe joint 9 is fixedly installed at both ends of the right side wall of the lower frame 1, a displacement locking part is movably and cooperatively installed in each connecting pipe joint 9, the right end of each displacement locking part is screwed through a corresponding threaded hole 10 in the right vertical section of the inverted U-shaped plate frame 8 and extends to the outside, and the two displacement locking parts drive the inverted U-shaped plate frame 8 to approach or move away from the middle partition plate 4 in a synchronous rotating state to adjust the width size of the first pouring cavity 2 and the second pouring cavity 3.

[0037] The locking clamping component mainly relies on the synchronous rotation of the two displacement locking members to drive the entire inverted U-shaped plate frame 8 to move along the left-right direction. During the displacement process, the U-shaped sliding frame formed by the left side fixedly welded end sliding baffle 6 and the connecting side plate 7 is translated, thereby achieving the purpose of adjusting the available width size of the current first pouring cavity 2 and the second pouring cavity 3.

[0038] In any of the above schemes, preferably, the displacement locking member includes an adjusting threaded rod 11 screwed through the corresponding threaded hole 10 on the right side vertical section of the inverted U-shaped plate frame 8. The left end of the adjusting threaded rod 11 is fixedly connected with a stepped shaft 1101 which extends into a stepped hole 12 inside the connecting pipe joint 9. An end baffle ring 13 is sleeved on the outer wall of the right side small diameter section of the stepped shaft 1101. The left side of the end baffle ring 13 is fixedly connected with the right end of the connecting pipe joint 9.

During the adjustment, the adjusting knob 14 is twisted to coaxially rotate the current adjusting threaded rod 11 and the stepped shaft 1101. During the rotation, the inverted U-shaped plate frame 8 is pushed or pulled to achieve the purpose of moving close to or away from the middle partition plate 4.

[0041] Embodiment 2: Compared with Embodiment 1, the difference lies in that it further includes the following technical features:

[0042] In any of the above schemes, preferably, a push shaft 15 is inserted and fitted at each end of the left side wall of the lower frame 1. The left end of the push shaft 15 extends to the left side outside of the lower frame 1. A push disc 16 is fixedly installed at the end of each push shaft 15. The right end of the push disc 16 abuts against the left side wall of the connecting side plate 7. A push spring 17 is sleeved on the outer wall of the push shaft 15 between each push disc 16 and the left side wall of the lower frame 1. The right end of each push spring 17 abuts against the push disc 16, and the left end of each push spring 17 abuts against the corresponding side wall of the lower frame 1.

[0043] When the inverted U-shaped plate frame 8 drives the U-shaped sliding frame formed by the two end sliding baffle plates 6 and the connecting side plate 7 to move to the position, in order to further ensure the stability of the structure, the pushing spring 17 is arranged to push the pushing disc 16 to realize the abutting of the left side positioning effect.

[0044] In any of the above schemes, preferably, the first pouring cavity 2 and the second pouring cavity 3 are used for pouring the precast beam in the working state.

[0045] When pouring the precast beam, the size of the currently used pouring cavity can be quickly adjusted according to the needs, achieving the purpose of adjusting the size of the mold as needed.

[0046] In any of the above schemes, preferably, the outer thread of the adjusting screw rod 11 is a trapezoidal thread. The trapezoidal thread can bear outward pushing expansion force during pouring, ensuring the effect of shaping the entire structure.

[0047] In any of the above schemes, preferably, the height of the middle partition plate 4 is greater than the height of the lower frame 1. Increasing the height of the middle partition plate 4 can reduce the probability of concrete material scattering towards the other side during pouring.

[0048] Specific working principle: Before pouring concrete for the precast beam, the entire structure is placed on the corresponding platform. According to the width design needs of the precast beam, the width of the first pouring cavity 2 or the second pouring cavity 3 currently needed for pouring is adjusted in advance. During adjustment, by screwing the corresponding locking clamping parts, one of the first pouring cavity 2 and the second pouring cavity 3 can be adjusted to increase the width, and the other can be adjusted to decrease the width, finally reaching the state of adjustment and locking. Then, by preventing the internal binding steel and using pouring equipment to pour concrete into the corresponding pouring cavity and vibrating as needed, the concrete is completely solidified into a precast beam.

[0049] As can be seen from the above, the precast beam mold can complete the rapid pouring and molding of precast beams of different widths, effectively improving the use efficiency of the mold and the manufacturing efficiency of the precast beam during the manufacturing of the precast beam. The size of the first pouring cavity 2 and the second pouring cavity 3 can be quickly adjusted, and after the adjustment is completed, it can be self-locked in time, which can complete the rapid pouring of precast beams with the same size or different sizes. The small parts on the entire mold do not need to be frequently disassembled after installation, effectively ensuring the integrity of the entire mold after moving and shifting, reducing the loss probability of small parts, improving the safety of the mold during use, and reducing the frequency of maintenance and replacement parts.
