Description

Technical Field

[0001] This utility model belongs to the field of prefabrication mold technology, specifically, it relates to a prefabrication mold frame device for cement houses. Background Technology

[0002] Precast concrete formwork refers to molds used to manufacture prefabricated concrete buildings, also known as precast monolithic concrete building molds. These molds play a crucial role in modern industrialized construction, gradually changing traditional building construction methods. Precast monolithic concrete building molds demonstrate significant advantages in practical applications; they can not only drastically shorten the construction cycle but also effectively reduce construction waste, aligning with the principles of green building.

[0003] After a concrete structure is cast using precast molds, the current demolding method mostly involves using a crane. When the crane is working, it lifts the precast concrete structure using wire ropes and hooks. However, as the concrete structure rises, the wire ropes and hooks sway under the crane's force, which can easily cause the walls of the concrete structure to collide with the molds and cause damage.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A precast concrete formwork device includes an inner formwork base, a first outer wall formwork, and a second outer wall formwork. The inner formwork base has a movable cavity on its inner side. A support seat is slidably disposed on the top inner wall of the movable cavity. A sealing plate is fixedly connected to the top of the support seat. The bottom of the sealing plate contacts the top outer wall of the inner formwork base. A lifting cylinder is fixedly installed on the bottom inner wall of the movable cavity. The piston rod of the lifting cylinder is connected to the bottom outer wall of the support seat. Symmetrically arranged support mechanisms are installed inside the movable cavity.

[0007] According to the aforementioned precast concrete formwork device, the support mechanism includes a lifting support rod, a support frame, and a sliding support. The support frame is fixedly connected to the bottom outer wall of the support base, and the top end of the lifting support rod is hinged to the support frame.

[0008] According to the precast formwork device for cement houses, the bottom inner wall of the movable cavity is provided with symmetrically arranged movable grooves, the sliding support is slidably connected to the inner wall of the movable groove, and the bottom end of the lifting support rod is hinged to the sliding support.

[0009] According to the aforementioned precast formwork device for cement houses, an opening is provided on one side of the inner formwork base, and a maintenance plate is installed on the inner wall of the opening. The maintenance plate and the side of the inner formwork base are on the same plane.

[0010] According to the precast formwork device for cement houses, two first outer wall molds are symmetrically arranged, and the first outer wall molds are symmetrically arranged on the left and right sides of the inner mold base.

[0011] According to the aforementioned precast formwork device for cement houses, two second outer wall molds are symmetrically arranged, and the second outer wall molds are symmetrically arranged on the front and rear sides of the inner mold base. The second outer wall molds and the first outer wall molds together form an outer mold frame structure.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention utilizes an inner mold base, a first outer wall mold, and a second outer wall mold for pouring concrete. After pouring, when the concrete is demolded using a crane, wire rope, and hook, a lifting cylinder simultaneously pushes the support base and sealing plate upwards. The support base and sealing plate then push the concrete structure upwards, ensuring that the concrete structure remains vertically upright under the lifting action of the lifting cylinder, support base, and sealing plate. This prevents the walls of the concrete structure from colliding with the inner mold base during demolding and causing damage, thus providing a good auxiliary demolding effect.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown, a precast concrete building formwork device includes an inner formwork base 1, a first outer wall formwork 2, and a second outer wall formwork 3. Two first outer wall formwork 2s are symmetrically arranged on the left and right sides of the inner formwork base 1. Two second outer wall formwork 3s are symmetrically arranged on the front and rear sides of the inner formwork base 1. The second outer wall formwork 3s and the first outer wall formwork 2 together form the outer formwork frame structure. The concrete building is poured using the inner formwork base 1, the first outer wall formwork 2, and the second outer wall formwork 3. After pouring, when demolding, the crane hook is connected to the roof connection of the concrete building. After connection, the first outer wall formwork 2 and the second outer wall formwork 3 are moved to the side of the concrete building, and then the concrete building can be lifted and demolded by the crane. An movable cavity is provided on the inner side of the inner formwork base 1. 7. A support seat 9 is slidably installed on the inner wall of the top of the movable cavity 7. A sealing plate 4 is fixedly connected to the top of the support seat 9. The bottom of the sealing plate 4 contacts the outer wall of the top of the inner mold base 1. A lifting cylinder 8 is fixedly installed on the inner wall of the bottom of the movable cavity 7. The piston rod of the lifting cylinder 8 is connected to the outer wall of the bottom of the support seat 9. When the cement chamber is lifted and demolded by a crane, the lifting cylinder 8 is activated, which pushes the support seat 9 and the sealing plate 4 upward. The support seat 9 and the sealing plate 4 push the cement chamber upward, so that the cement chamber always remains in a vertical upward state under the lifting action of the lifting cylinder 8, the support seat 9 and the sealing plate 4. This avoids the cement chamber wall from colliding with the inner mold base 1 during demolding and causing damage, thus playing a good auxiliary demolding role. Symmetrically arranged support mechanisms are installed in the movable cavity 7.

[0024] In a specific embodiment, the support mechanism includes a lifting rod 10, a support frame 11, and a sliding support 13. The support frame 11 is fixedly connected to the bottom outer wall of the support base 9. The top end of the lifting rod 10 is hinged to the support frame 11. The bottom inner wall of the movable cavity 7 has symmetrically arranged movable grooves 12. The sliding support 13 is slidably connected to the inner wall of the movable grooves 12. The bottom end of the lifting rod 10 is hinged to the sliding support 13. When the support base 9 moves upward, it drives the support frame 11 to move upward. The sliding support 13, which is matched with the support frame 11, causes the tilt angle of the lifting rod 10 to change. When the tilt angle of the lifting rod 10 changes, the movable grooves 12 can drive the sliding support 13 to move, so that the support frame 11, the lifting rod 10, and the sliding support 13 can provide stable support for the support base 9. An movable opening 5 is opened on one side of the inner mold base 1. An inspection plate 6 is installed on the inner wall of the movable opening 5. The inspection plate 6 and the side of the inner mold base 1 are on the same plane.

[0025] The implementation principle of a precast concrete formwork device for a cement house in this embodiment is as follows: In specific use, the cement house is poured using the inner formwork base 1, the first outer wall formwork 2, and the second outer wall formwork 3. After pouring, when demolding, the crane hook is connected to the roof connection of the cement house. After the connection is completed, the first outer wall formwork 2 and the second outer wall formwork 3 are moved to the side of the cement house. Then, the cement house can be lifted and demolded by the crane. At the same time, the lifting cylinder 8 is activated, causing the lifting cylinder 8 to push the support base 9 and the sealing plate 4 upward. The support base 9 and the sealing plate 4 push the cement house upward, so that the cement house is lifted. Under the lifting action of the hydraulic cylinder 8, support seat 9 and sealing plate 4, it always maintains a vertical upward movement, avoiding the collision between the cement chamber wall and the inner mold seat 1 during demolding and causing damage. It plays a good role in assisting demolding. When the support seat 9 moves upward, it drives the support frame 11 to move upward. The sliding support 13 provided with the support frame 11 changes the tilt angle of the lifting support rod 10. When the tilt angle of the lifting support rod 10 changes, the movable groove 12 provided with the support can drive the sliding support 13 to move, so that the support frame 11, lifting support rod 10 and sliding support 13 can provide stable support for the support seat 9.
