Description

Technical Field

[0001] This utility model relates to the field of precast beam production technology, specifically a precast beam production mold. Background Technology

[0002] Precast beams are beams that are prefabricated in a factory and then transported to the construction site for installation and fixation according to design requirements. Existing precast beam production molds can only produce precast beams with a single structure, which cannot take into account the production of hollow beams. Using multiple precast beam production molds not only requires placing a large number of molds on the construction site, but also occupies a large part of the construction site area. Therefore, those skilled in the art have provided a precast beam production mold to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a precast beam production mold to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a precast beam production mold, including a base, a mold body fixedly connected to the top of the base, an installation hole provided on one side inner wall of the mold body, and a sealing plate inserted through and sealed into the installation hole, a central rod fixedly connected to the inner side of the sealing plate, a top cover snapped onto the top of the mold body, two hydraulic rods symmetrically arranged on the top of the top cover, the telescopic ends of the two hydraulic rods fixedly connected to the same connecting plate, a connecting rod fixedly connected to the bottom of the connecting plate, and the connecting rod penetrating the top cover and extending into the mold body, and a pressure plate fixedly connected to the bottom end of the connecting rod.

[0005] As a further embodiment of this utility model: a heater is fixedly connected to the side of the mold body away from the sealing plate, and multiple heat-conducting pipes are vertically and symmetrically fixedly connected to the side of the heater close to the mold body, and the outer walls of the multiple heat-conducting pipes are tightly attached to the outer wall of the mold body.

[0006] As a further improvement of this utility model: both sides of the mold body are fixedly connected with clamping tubes, and the bottom of the top cover is symmetrically fixedly connected with two clamping rods, which are inserted through and clamped into the clamping tubes.

[0007] As a further improvement of this utility model: the top of the pressure plate and the top cover are symmetrically connected with two sets of insertion holes, which are located above the central rod.

[0008] As a further improvement of this utility model: grip rings are fixedly connected to both sides of the top cover, and the sealing plate is located on the lower side of the top cover.

[0009] As a further improvement of this utility model: two rectangular holes are symmetrically opened through one side of the base, and the top opening of the mold body and the bottom of the top cover are sealed and fitted together.

[0010] As a further embodiment of this utility model: the outer side of the pressure plate is fitted with the inner wall of the mold body, and a handle is fixedly connected to the side of the sealing plate away from the central rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The reinforcing bars can be inserted into the concrete through the insertion holes. Activating the heater heats multiple heat pipes, which then transfer heat to the entire mold body, accelerating the evaporation of moisture from the concrete and speeding up the molding process. Activating the two hydraulic rods retracts the connecting plate, causing it to descend. The descending connecting plate then lowers the connecting rod and pressure plate onto the concrete, making it more compact. Holding the handle and pulling the center rod and sealing plate backwards allows the entire precast beam to be pulled out of the mold body and finally removed from the sealing plate and center rod. At this point, the precast beam formed by the center rod is hollow.

[0013] This invention is simple to use. By injecting concrete into the mold body and molding it on the central rod, a hollow precast beam can be formed. When it is not necessary to produce hollow precast beams, the sealing plate can be replaced with a sealing plate without the central rod. Activating the two hydraulic rods can drive the pressure plate to descend and press on the concrete, which can make the concrete more compact. Through multiple insertion holes, steel bars can be inserted into the concrete, which facilitates the installation of steel bars in the precast beam. Attached Figure Description

[0020] Please see Figures 1-4 In this embodiment of the present invention, a precast beam production mold includes a base 1, a mold body 7 fixedly connected to the top of the base 1, an installation hole 17 is provided on one side inner wall of the mold body 7, and a sealing plate 9 is inserted through and sealed in the installation hole 17. A center rod 16 is fixedly connected to the inner side of the sealing plate 9. A top cover 12 is snapped onto the top of the mold body 7. Two hydraulic rods 13 are symmetrically arranged on the top of the top cover 12. The telescopic ends of the two hydraulic rods 13 are fixedly connected to the same connecting plate 14. A connecting rod 15 is fixedly connected to the bottom of the connecting plate 14, and the connecting rod 15 passes through the top cover 12 and extends into the mold body 7. A pressure plate 18 is fixedly connected to the bottom end of the connecting rod 15.

[0021] In this embodiment, a heater 6 is fixedly connected to the side of the mold body 7 away from the sealing plate 9, and multiple heat conduction pipes 5 are vertically and symmetrically fixedly connected to the side of the heater 6 close to the mold body 7, and the outer walls of the multiple heat conduction pipes 5 are tightly attached to the outer wall of the mold body 7.

[0022] In this embodiment, clamping tubes 3 are fixedly connected to both sides of the mold body 7, and two clamping rods 4 are symmetrically fixedly connected to the bottom of the top cover 12, with the clamping rods 4 penetrating and clamping into the clamping tubes 3.

[0023] In this embodiment, two sets of insertion holes 11 are symmetrically provided on the top of the pressure plate 18 and the top cover 12. The insertion holes 11 are located above the center rod 16. The top cover 12 is installed by inserting it into the clamping tube 3 through two clamping rods 4. The top cover 12 can be removed from the mold body 7, and then an appropriate amount of concrete slurry can be injected into the mold body 7. Then the top cover 12 is put back on for sealing. Insertion holes 11 are provided on both the top cover 12 and the pressure plate 18. At this time, the reinforcing bars can be inserted into the concrete through the insertion holes 11.

[0024] In this embodiment, grip rings 10 are fixedly connected to both sides of the top cover 12, and the sealing plate 9 is located on the lower side of the top cover 12.

The heater 6 can be activated to heat multiple heat conduction pipes 5. The heat conduction pipes 5 can conduct heat to the entire mold body 7, thereby accelerating the hydration of the concrete in the mold body 7. The evaporation of the concrete accelerates the molding process. After the two hydraulic rods 13 retract, they can drive the connecting plate 14 to descend. The descent of the connecting plate 14 will drive the connecting rod 15 and the pressure plate 18 to descend and press on the concrete, thereby making the concrete more compact. After removing the top cover 12, a release agent is injected into the mold body 7. Then, hold the handle 8 and pull the center rod 16 and the sealing plate 9 backward. At this time, the entire precast beam can be pulled out from the mold body 7 and finally removed from the sealing plate 9 and the center rod 16. The precast beam formed by the center rod 16 is now hollow.
