Description

Technical Field

[0001] This utility model belongs to the field of test chambers, specifically relating to an ultra-heavy-duty thermal insulation base plate for a whole vehicle-level test chamber. Background Technology

[0002] Environmental testing chambers, such as high and low temperature humidity test chambers, constant temperature and humidity test chambers, and thermal shock test chambers, have become indispensable tools for improving product quality and refining production processes. In these test chambers, heavy-duty load-bearing insulated base plates are a crucial component. These base plates must not only withstand the concentrated loads generated by large specimens, personnel movement, and vehicle traffic within the chamber, but also possess excellent thermal insulation properties to ensure the stability and uniformity of the temperature within the chamber. Therefore, the design of the heavy-duty load-bearing insulated base plate directly affects the accuracy and reliability of the test results. Utility Model Content

[0003] The purpose of this utility model is to provide an ultra-heavy-duty thermal insulation base plate for a vehicle-grade test chamber.

[0004] This utility model is implemented according to the following technical solution.

[0005] A heavy-duty insulated base plate for a vehicle-grade test chamber includes multiple base plates. Each base plate consists of a bottom carbon steel plate and multiple parallel H-beam supports arranged on the carbon steel plate. Adjacent H-beam supports are welded together by multiple parallel channel steels. Timber supports are also arranged in an array between adjacent H-beam supports. A steel plate is placed on top of each H-beam support. An epoxy resin plate and a stainless steel checkered plate are arranged sequentially from bottom to top above the timber supports and the steel plate. Polyurethane foam is filled in the gaps between the carbon steel plate, the H-beam supports, and the epoxy resin plate. Connecting channel steels for fixing are provided on the outermost sides of the multiple H-beam supports.

[0006] Furthermore, a drainage groove is provided between adjacent bottom plates of the plurality of bottom plates, and a perforated cover plate is provided above the drainage groove.

[0007] Furthermore, the carbon steel plate and the I-beam support are welded together.

[0008] Furthermore, the top of the wooden support and the epoxy resin board are bonded and fixed together using silicone sealant.

[0009] Furthermore, the I-beam support, steel plate, epoxy resin plate, and stainless steel patterned plate are connected by bolts.

[0010] Furthermore, the carbon steel plate, steel plate, epoxy resin plate, and stainless steel patterned plate are all rectangular.

[0011] Furthermore, the connecting channel steel is connected and fixed to the embedded C-shaped steel of the foundation to prevent horizontal displacement of the base plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The overall structure of this utility model enables modular installation, which shortens the installation cycle and facilitates subsequent maintenance and replacement.

[0014] 2. By setting up I-beam supports, channel steel and timber supports to maintain the shape of the base plate, and installing insulation material in between, the load-bearing capacity of the base plate is enhanced, heat conduction is effectively blocked, and the insulation effect is improved.

[0015] 4. Using timber supports can enhance the support capacity of the base plate, increase the load-bearing capacity, and reduce the self-weight of the base plate. In addition, arranging as many timber supports as possible can relatively reduce the amount of I-beam supports, reduce the downward transfer of heat, and avoid the cold bridge effect.

[0016] 5. High-quality insulation materials (such as polyurethane foaming agent) are used to fill the interlayer of the base plate and a high-efficiency insulation layer is laid under the base plate to form a continuous insulation layer, which effectively improves the insulation performance of the base plate.

[0017] 6. The use of stainless steel patterned plates improves the anti-slip performance of the base plate, eliminating the need for additional anti-slip materials.

[0018] 7. Drainage channels are installed between the various blocks of the base plate, which can be connected to the outside through drainage pipes to ensure smooth drainage of the base plate and avoid water accumulation.

[0019] 8. The composite structure of I-beams, channel steel, and timber supports enables a load-bearing capacity of 40t / ㎡. Attached Figure Description

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-7 As shown, a heavy-duty thermal insulation base plate for a vehicle-grade test chamber includes multiple base plates 1. Each base plate 1 includes a bottom carbon steel plate 111 and multiple parallel H-beam supports 112 arranged on the carbon steel plate 111. Any adjacent H-beam supports 112 are welded together by multiple parallel channel steels 113. Any adjacent H-beam supports 112 are also arranged in an array of wooden supports 114. A steel plate 115 is provided on the top of each H-beam support 112. Epoxy resin board 116 and stainless steel checkered plate 117 are arranged sequentially from bottom to top above the wooden supports 114 and the steel plate 115. Polyurethane foam 118 is filled in the gaps between the carbon steel plate 111, the H-beam supports 112 and the epoxy resin board 116. Connecting channel steels 119 for fixing are provided on the outer sides of the outermost two sides of the multiple H-beam supports 112.

[0030] The aforementioned vehicle-grade test chamber heavy-duty insulated base plate has drainage grooves 2 between adjacent base plates 1, and a perforated cover plate 3 is provided above the drainage grooves 2.

[0031] The carbon steel plate 111 of the vehicle-grade test chamber and the I-beam support 112 are welded together.

[0032] The top of the wooden support 114 of the vehicle-grade test chamber and the epoxy resin board 116 are glued and fixed together with silicone sealant.

[0033] The aforementioned vehicle-grade test chamber's heavy-duty insulated base plate is connected by bolts 4 through I-beam supports 112, steel plates 115, epoxy resin plates 116, and stainless steel patterned plates 117.

[0034] The aforementioned vehicle-grade test chamber's heavy-duty insulated base plate has rectangular carbon steel plate 111, steel plate 115, epoxy resin plate 116, and stainless steel patterned plate 117.

[0035] The aforementioned vehicle-grade test chamber's heavy-duty insulated base plate has its connecting channel steel 119 connected and fixed to the foundation C-shaped steel embedded part 5 to prevent horizontal displacement of the base plate.

[0036] The timber support 114 can enhance the support capacity of the base plate, increase the load-bearing capacity, and reduce the weight of the base plate. In addition, since the I-beam support 112 has a strong heat conduction capacity, arranging as many timber supports 114 as possible can relatively reduce the amount of I-beam support 112 used, which can also reduce the downward transfer of heat and avoid the cold bridge effect.

[0037] The polyurethane foam 118 filling the gaps between the I-beam support 112, the channel steel 113 and the timber support 114 has a heat insulation function.

[0038] The I-beam support 112, steel plate 115, epoxy resin plate 116 and stainless steel patterned plate 117 are fixed together by bolts 4, and silicone sealant is injected into the bolt holes for sealing.

[0039] A drainage groove 2 is provided at the joint between adjacent bottom plates 1, and condensate water inside the cabin can be discharged through a drainage pipe.

[0040] The channel steel 113, connecting channel steel 119, foundation channel steel 7, and channel steel I9 are all C-shaped.

[0041] The connecting channel steel 119 and the foundation C-shaped steel embedded part 5 are welded and fixed to prevent horizontal displacement of the base plate.

[0042] The specific steps for making each base plate are as follows:

[0043] 1. Place I-beam supports 112 side by side on the carbon steel plate 111, and weld the I-beam supports 112 and the carbon steel plate 111 together;

[0044] 2. Weld the I-beam supports 112 together with transverse channel steel 113 to form a load-bearing frame;

[0045] 3. Arrange timber supports 114 in an array between the I-beam supports 112;

[0046] 4. Install a steel plate 115 above the I-beam support 112;

[0047] 5. Lay epoxy resin board 116 and stainless steel patterned plate 117 on the timber support 114 and steel plate 115 in sequence. The top of the timber support 114 and the epoxy resin board 116 are glued and fixed together with silicone sealant. Use bolts 4 to connect and fix the I-beam support 112, steel plate 115, epoxy resin board 116 and stainless steel patterned plate 117.

[0048] The specific steps for using the entire base plate are as follows:

[0049] 1. Dig pit 6 in the ground, and bury the foundation channel steel 7 in the concrete of the foundation at the bottom of the pit in a rectangular array, with only the upper surface exposed.

[0050] 2. Based on the dimensions of each base plate 1, first weld the foundation C-shaped steel embedded parts 5 to the foundation channel steel 7, arranged in a checkerboard pattern;

[0051] 3. Then place the rigid high-efficiency insulation board 8 on the C-shaped steel embedded part 5 of the foundation;

[0052] 4. Then place the pre-assembled base plate 1 on the insulation plate 8;

[0053] 5. Weld the connecting channel steel 119 on both sides of the base plate 1 and the ends of the I-beam support 112 at the front and rear of the base plate 1 to the foundation C-shaped steel embedded parts 5. That is, the four sides of each base plate 1 are welded to the foundation C-shaped steel embedded parts 5. Fill the outer side of the I-beam support 112 on both sides with polyurethane foam 118.

[0054] 6. Finally, install channel steel I9 between adjacent base plates 1. Channel steel I9 is ​​welded to the C-shaped steel embedded part 5 of the foundation. Attach drainage trough 2 to channel steel I9. Cover drainage trough 2 with cover plate 3. Install all base plates 1 in sequence. The top surface of the entire base plate and the ground 10 are on the same horizontal plane.

[0055] In this way, the production and installation of the heavy-duty insulated base plate for the whole vehicle-level test chamber are realized, which can have the effects of load-bearing and heat preservation.
