Description

Technical Field

[0001] The utility model relates to the field of concrete prefabricated component production lines, in particular to a steaming device for prefabricated components with a bottom mold trolley. Background Art

[0002] Precast concrete components (PC components for short) such as box girders and T-girders need to be steam cured and spray cured after concrete pouring and vibration because they require appropriate temperature and humidity conditions to improve the strength of the concrete.

[0003] For the prefabricated component production line with bottom mold trolley, the current maintenance method is to fix the box beam or T beam on the bottom mold trolley, and then the box beam or T beam together with the bottom mold trolley enters the steam curing room, and steam curing and spray curing are carried out on the box beam or T beam. After the stages of static, heating, constant temperature, and cooling, the PC components such as box beams and T beams meet the strength requirements. Since the bottom mold trolley needs to be steamed and sprayed in the steam curing shed together with the prefabricated components, the electrical components such as the motor and control cabinet at the bottom of the bottom mold trolley will be affected by the high temperature and high humidity environment, which is not conducive to ensuring the normal use of the electrical components, and will lead to an increase in the curing space for steaming and spraying in the steam curing shed, resulting in a certain waste of steam and spray water. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a steaming and curing device for prefabricated components with a bottom mold trolley, which has a simple structure and is beneficial to avoiding the electrical components of the bottom mold trolley from being affected and reducing the waste of steam and spray water.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A steaming device for prefabricated components with a bottom mold trolley comprises a steaming chamber, wherein the steaming chamber comprises a steel structure body and concrete walls arranged below both sides of the steel structure body, the length of the steel structure body is less than the length of the bottom mold trolley, sealing doors for sealing the two ends of the bottom mold trolley are arranged at both ends of the steel structure body, and sealing members for sealing the sides of the bottom mold trolley are arranged on the concrete wall.

[0007] As a further improvement of the above technical solution: the height of the concrete wall is greater than or equal to the height of the bottom formwork trolley, and the length is greater than or equal to the length of the steel structure body.

[0008] As a further improvement of the above technical solution: the sealing member is fixedly mounted on the concrete wall by fasteners, and the sealing member extends toward the side of the bottom form trolley.

[0009] As a further improvement of the above technical solution: the sealing member is a sealing brush or a sealing rubber strip.

[0011] As a further improvement of the above technical solution: the flexible door includes a plurality of door panels, adjacent door panels are hinged, and a first thermal insulation layer is provided on the door panels.

[0012] As a further improvement of the above technical solution: the steel structure body includes a frame and a second thermal insulation layer arranged on the frame, and a diagonal brace is provided between the side surface and the top surface of the frame.

[0013] As a further improvement of the above technical solution: the second thermal insulation layer is arranged on the top surface and side surfaces of the frame.

[0014] As a further improvement of the above technical solution: a steaming pipeline and / or a spraying pipeline is provided inside the steel structure body.

[0015] Compared with the prior art, the utility model has the following advantages: the utility model discloses a steaming and curing device for prefabricated components with a bottom mold trolley. After the bottom mold trolley drives the template and the prefabricated components into the steaming and curing chamber, since the length of the bottom mold trolley is less than the length of the steel structure body, the two ends of the bottom mold trolley are located outside the steel structure body. After the sealing doors at both ends of the steel structure body are closed, the sealing doors can be pressed on the bottom mold trolley, thereby sealing the ends of the bottom mold trolley. The sealing parts on the concrete wall seal the sides of the bottom mold trolley, thereby forming a sealed space above the bottom mold trolley. The electrical components at the bottom of the bottom mold trolley are located outside the sealed space, which is beneficial to avoid being affected by the steam and / or spray water generated during the steaming and curing process. At the same time, since there is no need to introduce steam and / or spray water into the space below the bottom mold trolley, the waste of steam and / or spray water can also be reduced, resources can be saved, and the use cost can be reduced.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Figures 1 to 6An embodiment of the steaming curing device for prefabricated components with a bottom mold trolley of the utility model is shown. The steaming curing device for prefabricated components with a bottom mold trolley of the utility model comprises a steaming curing chamber 1, the steaming curing chamber 1 comprises a steel structure main body 11 and a concrete wall 12 arranged below the two sides of the steel structure main body 11, the length of the steel structure main body 11 is less than the length of the bottom mold trolley 2, and sealing doors 3 for sealing the two ends of the bottom mold trolley 2 are arranged at both ends of the steel structure main body 11, and a sealing member 6 for sealing the side of the bottom mold trolley 2 is arranged on the concrete wall 12. In the embodiment, when the bottom mold trolley 2 enters the steaming curing chamber 1, since the steaming curing chamber 1 is divided into two layers, the lower layer adopts the concrete wall 12, which not only increases the overall structural strength of the steaming curing chamber 1, but also is conducive to rust prevention of the bottom of the steaming curing chamber 1, that is, the falling water droplets will not soak the steel structure main body 11, and at the same time, the lower layer does not need to be passed with steam, so the concrete wall 12 can be provided with no insulation material relative to the steel structure main body 11. Preferably, the height of the concrete wall 12 is greater than the height of the bottom mold trolley 2, and the length is greater than the length of the steel structure body 11, that is, a certain margin is left for both the height and the length, so as to ensure that the seal 6 can effectively seal the side of the bottom mold trolley 2, and at the same time facilitate the reliable installation of the steel structure body 11 on the concrete wall 12. Of course, in other embodiments, the height and length of the concrete wall 12 can also be appropriately reduced, but the height should not be less than the height of the bottom mold trolley 2, and the length should not be less than the length of the steel structure body 11.

[0029] In the steaming and curing device for prefabricated components with a bottom mold trolley of the present embodiment, after the bottom mold trolley 2 drives the template 21 and the prefabricated components into the steaming and curing chamber 1, since the length of the bottom mold trolley 2 is less than the length of the steel structure body 11, the two ends of the bottom mold trolley 2 are located outside the steel structure body 11. After the sealing doors 3 at the two ends of the steel structure body 11 are closed, the sealing doors 3 can be pressed on the bottom mold trolley 2, thereby sealing the ends of the bottom mold trolley 2, and the sealing member 6 on the concrete wall 12 seals the side of the bottom mold trolley 2, thereby forming a sealed space above the bottom mold trolley 2, and the electrical components at the bottom of the bottom mold trolley 2 are located outside the sealed space, which is conducive to avoiding the influence of steam and / or spray water (the spray water is in an atomized state) generated during the steaming and curing process. At the same time, since there is no need to introduce steam and / or spray water into the space below the bottom mold trolley 2, the waste of steam and / or spray water can also be reduced, resources are saved, and the use cost is reduced. The structure is reasonable and effective. Preferably, bolts may be embedded in the concrete wall 12 , and the steel structure body 11 may be fixed to the concrete wall 12 by the embedded bolts. The concrete wall 12 may provide reliable support for the steel structure body 11 and ensure the installation stability of the steel structure body 11 .

[0030] Furthermore, in this embodiment, the seal 6 is fixedly mounted on the concrete wall 12 by fasteners (not shown in the figure, such as bolts, screws, etc.), and the seal 6 extends to the side of the bottom mold trolley 2. When the bottom mold trolley 2 is in place, the seal 6 can overlap or abut the side of the bottom mold trolley 2, and the structure is simple, reliable, and easy to replace.

[0031] Preferably, in this embodiment, the sealing member 6 is a sealing brush. The bristles of the sealing brush can provide a good sealing effect after contacting the bottom mold trolley 2 to prevent steam and spray water from leaking. Of course, in other embodiments, the sealing member 6 can also be a sealing strip.

[0032] Furthermore, in this embodiment, the sealing door 3 is a flexible door, and door lifting tracks 111 are provided at both ends of the steel structure body 11, and a door translation track 112 arranged along the length direction of the steel structure body 11 is provided at the top, and the door translation track 112 is connected to the door lifting track 111. When closing the door, the sealing door 3 first translates along the door translation track 112, and then descends along the door lifting track 111 until the sealing door 3 contacts the end of the bottom mold trolley 2, at which time the sealing of the two ends of the bottom mold trolley 2 can be achieved, and the structure is simple and effective. Compared with only using the lifting method to open and close the door, the space in the length direction of the steel structure body 11 can be fully utilized, and the height of the steel structure body 11 can be reduced.

[0033] As a preferred embodiment, the flexible door includes multiple door panels, and adjacent door panels are hinged to achieve bending of the sealed door 3, which is convenient for moving on the door lifting track 111 and the door translation track 112. A first thermal insulation layer (not shown in the figure) is provided on the door panel. The first thermal insulation layer is beneficial to reducing heat loss in the steel structure body 11 and reducing energy consumption.

[0034] Furthermore, in this embodiment, the steel structure body 11 includes a skeleton 113 (for example, a skeleton 113 welded from steel components, which is beneficial to ensuring the structural strength of the steel structure body 11 itself) and a second thermal insulation layer 114 arranged on the skeleton 113. The provision of the second thermal insulation layer 114 is beneficial to reducing heat loss in the steel structure body 11 and reducing energy consumption. A diagonal brace 115 is provided between the side and top surface of the skeleton 113. The diagonal brace 115 can further increase the structural strength of the skeleton 113 and improve the wind resistance.

[0035] As a preferred embodiment, the second thermal insulation layer 114 is disposed on the top surface and the side surface of the frame 113, which is beneficial to comprehensively reduce the heat loss in the steel structure body 11 and reduce energy consumption.

[0036] According to actual maintenance requirements, a steam curing pipeline 4 and / or a spraying pipeline 5 can be arranged inside the steel structure body 11. The steam curing pipeline 4 and the spraying pipeline 5 output steam and spray water respectively to cure the prefabricated components. Preferably, the steam curing pipeline 4 and the spraying pipeline 5 can be arranged on both sides of the steel structure body 11, which is conducive to ensuring the uniformity of temperature and humidity in the steel structure body 11.

[0037] Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
