Description

Technical Field

[0001] This utility model relates to the field of precast beam production technology, specifically to the bottom mold structure for producing precast beams. Background Technology

[0002] The bottom formwork structure for producing precast beams refers to the mold used to support and fix the shape and position of concrete during the pouring process. It is usually made of strong materials such as steel or concrete, with sufficient strength and stability to withstand the weight of the newly poured concrete and various loads during construction. The design of the bottom formwork needs to take into account the size, shape and position of the precast beam and the embedded parts to ensure that the precast beam can meet the design requirements and construction standards after demolding.

[0003] Currently, when using the bottom formwork structure, concrete is poured onto the surface of the steel panel. Due to the fluidity of concrete, it flows in different directions, causing the bottom formwork panel to bend due to uneven pressure. At the same time, prolonged exposure to high pressure can cause overall structural deformation, resulting in uneven bottoms of the precast beams and affecting production quality. Therefore, a bottom formwork structure for producing precast beams has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bottom mold structure for producing precast beams, which has advantages such as reducing the pressure on the bottom mold structure during precast beam production and increasing its service life, thus solving the problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom mold structure for producing precast beams, comprising horizontal channel steel, longitudinal channel steel and panel steel plate, wherein the outer wall of the horizontal channel steel is provided with a support structure;

[0006] The support structure includes four limiting frames fixedly installed on the top of the crossbar channel steel and the bottom of the panel steel plate, respectively. A load-bearing seat is slidably connected between two adjacent limiting frames. Four mounting plates are fixedly installed between the crossbar channel steel and the panel steel plate. Threaded rods are movably installed inside the mounting plates. A threaded seat is fixedly installed on the left outer wall of the load-bearing seat. Four rubber pads are movably installed on the top inner wall of the crossbar channel steel. A support steel plate is fixedly installed on the bottom outer wall of the rubber pads.

A nut is threadedly connected to the outer peripheral wall of the support rod. A support base is fixedly installed on the bottom outer wall of the support rod. Five support frames are fixedly installed on the bottom outer wall of the support steel plate.

[0007] Furthermore, both the crossbar channel steel and the supporting steel plate are slidably connected to two limiting rods inside. The bottom inner wall of the crossbar channel steel is fixedly installed with two card seats. The limiting rods are slidably connected inside the card seats and are of the same size. Both the crossbar channel steel and the supporting steel plate are provided with a number of sliding holes inside. The limiting rods are slidably connected inside the sliding holes and are of the same size.

[0008] Furthermore, the limiting frame is U-shaped, and the two limiting frames are slidably connected to the top, bottom, left and right outer walls of the load-bearing seat, respectively. The threaded rod passes through the interior of the mounting plate and is threadedly connected to the interior of the threaded seat.

[0009] Furthermore, the four rubber pads are equidistantly distributed on the top of the supporting steel plate, and the five supporting frames are equidistantly distributed on the bottom of the supporting steel plate, with the supporting steel plate and the supporting frames installed in a staggered manner.

[0010] Furthermore, the supporting steel plate has grooves on both the left and right sides, the supporting rod is slidably connected inside the groove and is of a suitable size, and the outer walls of the supporting ring and nut are respectively attached to the bottom outer wall and the top outer wall of the supporting steel plate.

[0011] Furthermore, the outer peripheral wall of the support ring is provided with a threaded groove, which is located above the support steel plate, and the nut is threadedly connected to the threaded groove and is of a suitable size.

[0012] Furthermore, the number of longitudinal channel steels is five and they are welded to the top of the transverse channel steels, and the panel steel plate is welded to the top of the longitudinal channel steels.

[0013] Furthermore, a limiting plate is fixedly installed inside the limiting frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This precast beam production bottom formwork structure uses the steel panel to position the load-bearing base, which in turn supports the bottom of the steel panel, reducing the impact of pressure on the steel panel and preventing deformation. Rubber pads reduce pressure concentration on the bottom formwork, preventing damage due to excessive localized pressure. The entire bottom formwork is supported by support frames, support steel plates, support rods, support rings, and support bases, significantly reducing the impact of pressure on the bottom formwork, improving its service life, and enhancing the quality of precast beam production.

Two support rods 11 are slidably connected inside the support steel plate 10. A support ring 12 is fixedly installed on the outer peripheral wall of the support rod 11. A nut 13 is threadedly connected to the outer peripheral wall of the support rod 11. Sliding grooves are opened on both the left and right sides of the support steel plate 10. The support rods 11 are slidably connected inside the sliding grooves and are of a suitable size. The outer walls of the support rings 12 and the nuts 13 on opposite sides are respectively attached to the bottom outer wall and the top outer wall of the support steel plate 10. Sliding grooves are opened on both the left and right sides of the support steel plate 10. The support rods 11 are slidably connected inside the sliding grooves and are of a suitable size. The outer walls of the support rings 12 and the nuts 13 on opposite sides are respectively attached to the bottom outer wall and the top outer wall of the support steel plate 10.

[0027] A support base 14 is fixedly installed on the bottom outer wall of the support rod 11, and five support frames 15 are fixedly installed on the bottom outer wall of the support steel plate 10.
