Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pipe pile curing technology, specifically relating to a concrete pipe pile curing test chamber. Background Technology
[0002] Concrete pipe piles are prefabricated in factories, and steam curing is required during the production process. Different specifications and standards of concrete pipe piles require different curing conditions. In actual production, curing tests need to be conducted on each batch of pipe piles to determine the optimal curing conditions while ensuring certain production costs and efficiency. Existing steam curing chambers for concrete pipe piles can only cure the pipe piles within the chamber under specific temperature, humidity, and time conditions, making it impossible to create different curing conditions for separate curing tests on different pipe piles. Utility Model Content
[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a concrete pipe pile curing test chamber, including a box body with an opening at the top, the opening being covered by a box lid, an upper and lower passage in the middle of the box body, and the interior of the box body being divided into several steam curing chambers from top to bottom by several layers, with pipe pile support frames respectively provided on both sides of the upper and lower passages in the steam curing chambers. Each layer consists of two fixed layers and one movable layer. One side of the fixed layer is fixedly connected to the box body, and the movable layer is located in the upper and lower passages, with both sides of the movable layer resting on the two fixed layers. Several steam nozzles are provided above each pipe pile support frame, and steam is sprayed from the steam nozzles. Each steam curing chamber is equipped with a heating device and a temperature and humidity detection device.
[0004] As a preferred embodiment of the above technical solution, the bottom of the box is provided with a drain pipe, and several drain holes are provided on both sides of the movable shelf. Two adjacent steam curing chambers are connected through the drain holes on the corresponding movable shelf.
[0005] As a preferred embodiment of the above technical solution, a number of lifting lugs are fixedly connected to the movable shelf.
[0006] As a preferred embodiment of the above technical solution, there is a gap between the bottommost layer of the pipe pile support frame and the bottom of the box body.
[0007] As a preferred embodiment of the above technical solution, the pipe pile support frame is composed of several support arms arranged at intervals in sequence, one end of the support arm is fixedly connected to the box body, and the support arms in the same pipe pile support frame are fixedly connected by several connecting rods.
[0008] As a preferred embodiment of the above technical solution, the end of the support arm near the channel is bent upwards to form an anti-detachment part.
[0009] The beneficial effects of this utility model are: the concrete pipe pile curing test chamber of this utility model can be internally divided as needed to form steam curing chambers with different curing conditions for oxidation testing of pipe piles. Alternatively, the steam curing chambers can be connected after the divisions are removed, allowing pipe piles to be cured and used in production under the same curing conditions. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0011] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0012] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0014] like Figure 1As shown, the concrete pipe pile curing test chamber includes a box body 1 with an opening at the top, covered by a box cover 2. The interior of the box body 1 has a vertical passage 3 in the middle. The interior of the box body 1 is divided into several curing chambers 4 from top to bottom by several shelves. Pipe pile support frames 5 are respectively installed on both sides of the vertical passage 3 in the curing chamber 4. Each shelf consists of two fixed shelves 6 and one movable shelf 7. One side of the fixed shelf 6 is fixedly connected to the box body 1. The movable shelf 7 is located within the vertical passage 3, with its two sides resting on the two fixed shelves 6. Several steam nozzles 8 are installed above each pipe pile support frame 5, spraying steam. Each curing chamber 4 is equipped with a heating device 9 and a temperature and humidity detection device. The steam nozzles 8 are connected to a steam engine, spraying steam at a certain temperature to maintain a specific humidity level within the curing chamber 4. The heating device 9 heats each curing chamber 4 to maintain a specific temperature. This allows the enclosure 1 to be divided into multiple independently controllable steam curing chambers 4, enabling steam curing tests on the pipe piles and quickly determining the optimal curing parameters. When not conducting curing tests, the movable shelves 7 can be removed to ensure consistent curing conditions within the enclosure for pipe pile curing production. The enclosure 1 is typically located in an underground foundation pit, providing good insulation. Existing technologies, such as resistance wire heaters, are used for the heating device 9. The temperature and humidity detection device is also existing technology; commercially available products with real-time temperature and humidity monitoring capabilities can be purchased.
[0015] Furthermore, a drain pipe 10 is provided at the bottom of the chamber 1, and several drain holes 11 are provided on both sides of the movable shelf 7. Two adjacent steam curing chambers 4 are connected through the drain holes 11 on the corresponding movable shelf 7. The condensate formed by steam condensation can be gradually discharged to the bottom of the chamber 1 through the drain holes 11, and then discharged from the drain pipe 10.
[0016] Furthermore, several lifting lugs 12 are fixedly connected to the movable shelf 7. The movable shelf 7 can be formed by sequentially splicing several small boards, thus avoiding the movable shelf 7 being too large and difficult to install and remove. Each small board is provided with lifting lugs 12 to facilitate the installation and removal of the movable shelf 7.
[0017] Furthermore, there is a gap between the bottommost pipe pile support frame 5 and the bottom of the box body 1. This prevents the bottommost pipe piles from being soaked by condensate that has not been drained in time, which would affect the steam curing effect of the pipe piles.
[0018] Furthermore, the pipe pile support frame 5 is composed of several support arms arranged at intervals in sequence. One end of each support arm is fixedly connected to the housing 1, and the support arms in the same pipe pile support frame 5 are fixedly connected to each other by several connecting rods. In this way, when the pipe pile is placed into or taken out of the housing 1, a crane can be used with cables to lift the pipe pile for loading and unloading.
[0019] Furthermore, the end of the support arm near the channel is bent upwards to form an anti-slip section 13. The anti-slip section 13 prevents the pipe pile on the support arm from slipping off.
[0020] It is worth mentioning that the technical features of the heating device and temperature and humidity detection device involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0021] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
