Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated walls, in particular to a high-efficiency production line for prefabricated walls. Background Art

[0002] Prefabricated walls typically consist of two outer layers (usually panels made of concrete or lightweight materials) and a central connecting layer (which may be made of insulation, sound insulation, or other functional materials). These two outer layers and the central connecting layer are typically connected using embedded parts, welding, bonding, or bolting. To simplify the construction process and increase construction speed, existing technologies generally use bonding.

[0003] The existing technology bonds the two outer layers and the middle connecting layer by gluing. However, the adhesive used for bonding is sensitive to temperature changes, especially in the winter when the temperature in the workshop is low, which reduces the bonding performance of the adhesive and affects the connection effect between the middle connecting layer and the outer layer. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a high-efficiency production line for prefabricated walls.

[0005] The technical solution of this utility model is as follows:

[0006] A high-efficiency prefabricated wall production line includes a prefabricated component pressing table for laying out prefabricated components. The prefabricated components include outer panels stacked and bonded together and a supporting frame thereon. A heating mechanism is provided on the upper end surface of the prefabricated component pressing table and arranged horizontally therewith. The heating mechanism includes a heat preservation box and a serpentine tube disposed therein. The serpentine tube has a water inlet and a water outlet, each of which is connected to an external circulating heating furnace. The outer panels are located above the heat preservation box, and a heating opening is provided above the heat preservation box.

[0007] A plurality of flattening mechanisms are provided above the heating mechanism and are arranged at intervals along the length direction of the preform pressing table. A single flattening mechanism includes a support frame and a plurality of pressing devices arranged thereon and capable of pressing the preform downward. The plurality of pressing devices are arranged along the width direction of the preform pressing table.

[0008] The prefabricated parts are laid flat on the upper surface of the insulation box through external loading equipment. After the adhesive is applied between the support frame and the outer panel, the different positions of the support frame are pressed downward against the outer panel by controlling multiple pressing devices, and the upper end surface of the support frame is flattened, which is conducive to the bonding and fixation of the outer panel on the other side of the support frame. When the temperature is low or the adhesive needs to be heated, hot water is supplied to the serpentine pipe through an external circulation heating furnace to increase the temperature inside the insulation box, and the heat is transferred to the prefabricated parts through the main body of the insulation box and the heating opening, which helps the adhesive to better bond the outer panel and the support frame.

[0009] In order to prevent the water in the serpentine pipe from freezing or to accelerate the rapid increase in the water temperature in the serpentine pipe when the work is stopped in winter, multiple sections of the serpentine pipe close to the insulation box are passed through the insulation box and located outside the insulation box. They are drain sections with drain valves. When the work is stopped in winter, the circulating heating furnace can continue to supply high-temperature water to the serpentine pipe. If the circulating heating furnace stops supplying water, the water in the serpentine pipe will be quickly drained through the drain valve to avoid freezing and facilitate the rapid increase in the temperature of the serpentine pipe when the water is supplied next time.

[0010] In order to facilitate rapid water discharge at different positions of the serpentine pipe, multiple water discharge pipe sections are arranged at intervals along the length direction of the prefabricated part pressing table, and the water discharge pipe sections located on both outer sides are not close to the water inlet and outlet.

[0011] In order to facilitate the upper surface of the insulation box to stably support the preform and to better transfer the temperature to the preform, multiple heating openings are provided, which are arranged at intervals along the length or width direction of the preform pressing table, and the minimum width of the heating opening is smaller than the minimum width of the outer panel.

[0012] The serpentine pipe is horizontally laid in the insulation box. In order to facilitate the drainage of water in the serpentine pipe and increase the water discharge speed in the serpentine pipe, multiple water discharge pipe sections are arranged on different sides.

[0013] Regarding the specific structure of the support frame, the support frame includes a vertical main support and a cantilever vertically connected to its upper part. The cantilever is parallel to the upper end surface of the prefabricated part pressing table. Multiple clamping devices are detachably connected to the lower part of the cantilever and are arranged at intervals along the length of the cantilever.

[0014] The width of the prefabricated part is consistent with the width of the prefabricated part pressing table. The widths of prefabricated parts of different models are different. In order to facilitate the adaptability of the pressing device to press different types of prefabricated parts at different positions so that the pressing force is more uniform, the length of the cantilever is adjustable.

[0015] The structure of the cantilever is that the cantilever comprises a first hollow long arm and a second hollow long arm inserted therein, and the first hollow long arm is provided with an electric push rod capable of driving the second hollow long arm to slide.

[0016] In order to improve the downward pressure of multiple pressing devices on different positions of the support frame and improve the pressing and bonding effect between different positions of the support frame and the outer plate, one end of the first hollow long arm is rotatably connected to the upper part of the vertical main support through a rotating rod.

[0017] In order to increase the contact area between the multiple pressing devices and the support frame so that the pressing force is more evenly distributed at different positions of the support frame, the lower ends of the multiple pressing devices can be pressed and connected to the prefabricated parts through the pressing plate.

[0018] The beneficial effect of the present invention is that a heating mechanism is provided on the upper end surface of the prefabricated component pressing table in the horizontal direction, and the outer panels of the prefabricated component are laid flat on the heat-insulating box of the heating mechanism. The temperature is transferred upward to the prefabricated component through the serpentine tube, so that the adhesive of the outer panels and the supporting frame can improve its bonding performance at a suitable temperature, thereby improving the bonding effect and quality of the lower outer panels and the supporting frame, as well as the supporting frame and the upper outer panels.

[0019] Different sections of the serpentine pipe are arranged on the outside of the insulation box, and a drain valve is provided on the drain pipe section. When the work is stopped in winter or the circulating heating furnace stops supplying water, the water in the serpentine pipe can be quickly drained through the drain valve to avoid the water in the serpentine pipe from freezing, and it is conducive to quickly raising the temperature in the serpentine pipe when the water is supplied next time;

[0020] Multiple water discharge pipe sections are arranged at intervals along the length direction of the prefabricated component pressing table, and the water discharge pipe sections located on both outer sides are not close to the water inlet and outlet, so as to facilitate rapid water discharge at different positions of the serpentine pipe.

[0021] In order to facilitate the upper surface of the insulation box to stably support the preform and to better transfer the temperature to the preform, a plurality of heating openings are provided, which are arranged at intervals along the length or width direction of the preform pressing table.

[0029] See also Figure 1 、 Figure 2 and Figure 3As shown, a high-efficiency prefabricated wall production line includes a prefabricated component pressing table 1 for laying prefabricated components flatly. The prefabricated components include outer panels 2 stacked and bonded together and a supporting frame 3 thereon. The upper end surface of the prefabricated component pressing table 1 is provided with a heating mechanism for heating or insulating the adhesive used on the prefabricated components thereon, thereby facilitating the adhesive to better bond and fix the two outer panels 2 and the supporting frame 3, thereby improving the production quality of the prefabricated panels. The heating mechanism is arranged horizontally and includes an insulation box 4 and a serpentine tube 5 disposed therein. The serpentine tube 5 has a water inlet 501 and a water outlet 502, each of which is connected to an external circulating heating furnace. The bottom outer panel 2 is located above the insulation box 4, and a heating opening 401 is provided above the insulation box 4.

[0030] In order to prevent the water in the serpentine tube 5 from freezing during winter shutdown or to accelerate the rapid increase in the water temperature in the serpentine tube 5, multiple sections of the serpentine tube 5 close to the insulation box 4 are passed through the insulation box 4 and located outside the insulation box 4. They are the drain pipe sections 503, and a drain valve 6 is provided on the drain pipe section 503. When the circulation heating furnace is shut down in winter, the circulation heating furnace can continue to supply high-temperature water to the serpentine tube 5. If the circulation heating furnace stops supplying water, the water in the serpentine tube 5 will be quickly drained through the drain valve 6 to avoid freezing and facilitate the rapid increase in the temperature of the serpentine tube 5 when the water is supplied next time.

[0031] To facilitate rapid water drainage at various locations within the serpentine 5, multiple drain sections 503 are spaced apart along the length of the preform pressing platform 1. The outer drain sections 503 are located away from the water inlet 501 and outlet 502. The serpentine 5 is laid horizontally within the insulation box 4. To facilitate drainage and increase the speed of water drainage within the serpentine 5, the multiple drain sections 503 are arranged on different sides.

[0032] See also Figure 4 As shown, in order to facilitate the upper surface of the insulation box 4 to stably support the preform and to better transfer the temperature to the preform, a plurality of heating openings 401 can be provided, which are arranged at intervals along the length or width direction of the preform pressing table 1. In this embodiment, only one heating opening 401 is provided, and the minimum width of the heating opening 401 is smaller than the minimum width of the outer panel 2.

[0033] See also Figure 1As shown, multiple flattening mechanisms are provided above the heating mechanism. These flattening mechanisms are located above the preform support frame 3 or above the outer panel 2 above the support frame 3. During bonding, they can press and flatten the support frame 3 and the uppermost outer panel 2 downward, thereby increasing the bonding area and strength between the support frame 3 and the two outer panels 2. The flattening mechanisms are arranged at intervals along the length of the preform pressing platform 1. A single flattening mechanism includes a support frame and multiple pressing devices 11 disposed thereon and capable of pressing the preform downward. The multiple pressing devices 11 are arranged along the width of the preform pressing platform 1.

[0034] The prefabricated parts are laid flat on the upper surface of the insulation box 4 through external loading equipment. After the adhesive is applied between the support frame 3 and the outer panel 2, the multiple pressing devices 11 are controlled to press down, so that different positions of the support frame 3 are pressed downward to the outer panel 2, and the upper end surface of the support frame 3 is flattened, which is conducive to the bonding and fixation of the outer panel 2 on the other side of the support frame 3. When the temperature is low or the adhesive needs to be heated, hot water is supplied to the serpentine tube 5 through an external circulation heating furnace, so that the temperature inside the insulation box 4 increases, and the heat is transferred to the prefabricated parts through the main body of the insulation box 4 and the heating opening 401, which helps the adhesive to better bond the outer panel 2 and the support frame 3.

[0035] See also Figure 1 As shown, regarding the specific structure of the support frame, the support frame includes a vertical main support 7 and a cantilever vertically connected to its upper part, the cantilever is parallel to the upper end surface of the preform pressing table 1, and multiple clamping devices 11 are detachably connected to the lower part of the cantilever and are arranged at intervals along the length direction of the cantilever.

[0036] The width of the preform is consistent with the width of the preform pressing platform 1, and the length of the preform is consistent with the length of the preform pressing platform 1. The widths of different types of preforms are different. In order to facilitate the adaptability of the pressing device 11 to press different types of preforms at different positions, so that the pressing force is more uniform, the length of the cantilever is adjustable. The cantilever of this embodiment includes a first hollow long arm 8 and a second hollow long arm 9 inserted therein. One end of the first hollow long arm 8 is arranged near the vertical main support 7. The first hollow long arm 8 is provided with an electric push rod 10 that can drive the second hollow long arm 9 to slide. The space inside the first hollow long arm 8 of this embodiment is relatively large, and the electric push rod 10 can be installed inside the first hollow long arm 8 along its length direction, thereby reducing the space occupied by the electric push rod 10 when it is set outside, or reducing the impact on the installation or movement position of the pressing device thereon; and the electric push rod 10 can also be arranged on the outside of the first hollow long arm 8 without hindering the installation or movement position of the pressing device.

[0037] A chain 14 is provided at the end of the second hollow long arm 9 away from the vertical main support 7. The chain 14 is slidably connected to the outer side of the preform pressing platform 1. The sliding direction is the length direction of the preform pressing platform 1. The length of the chain 14 is set according to the height of the second hollow long arm 9. The chain 14 is used to support and tighten the end of the second hollow long arm 9 away from the vertical main support 7 when the clamping device 11 is pressed down, so as to prevent the end of the second hollow long arm 9 away from the vertical main support 7 from warping.

[0038] See also Figure 1 and Figure 3 As shown, multiple pressing devices 11 press down on different positions of the support frame 3 to improve the pressing and bonding effect between the support frame 3 and the outer panel 2 at different positions, which is conducive to better distribution of the pressing force. Therefore, one end of the first hollow long arm 8 is rotatably connected to the upper part of the vertical main support 7 through a rotating rod 13, and the rotating rod 13 is vertically inserted into the upper part of the vertical main support 7. The upper part of the rotating rod 13 is fixedly connected to one end of the first hollow long arm 8, so that multiple pressing devices 11 on the same cantilever can follow the cantilever to rotate a certain angle, so that multiple pressing devices 11 press down on different positions on the prefabricated part. The pressing device 11 is a hydraulic cylinder or an electric push rod 10, and multiple pressing devices 11 can be controlled separately. If a part of the prefabricated part is uneven or warped, the pressing device 11 at the corresponding position is controlled separately to cooperate with other pressing devices 11 to press the prefabricated part downward, which facilitates the bonding of the two outer panels 2 and the support frame 3 and improves the flatness of the prefabricated part.

[0039] In order to increase the contact area between the multiple clamping devices 11 and the supporting frame 3, so that the clamping force is more evenly distributed at different positions of the supporting frame 3, the lower ends of the multiple clamping devices 11 can be clamped and connected to the prefabricated part through the clamping plate member 12. The lower end surface of the clamping plate member 12 is flat, which can increase the contact area with the outer panel 2 or the supporting frame 3 in the prefabricated part, so that the clamping force of the clamping device 11 is evenly distributed downward on the prefabricated part, avoiding the phenomenon of warping or unevenness on one side of the prefabricated part.
