Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, specifically relating to a construction method and apparatus for high-efficiency thermal insulation composite walls for building envelopes. Background Technology
[0002] With the continuous improvement of building energy efficiency standards, especially the promotion of passive ultra-low energy buildings and near-zero energy buildings, the thermal insulation performance of building envelopes has become crucial for reducing building operating energy consumption and improving indoor thermal comfort. Traditional composite wall construction often employs layered casting or external insulation board application to form an outer protective layer, an insulation layer, and an inner structural layer. However, existing technologies have the following shortcomings: 1. The construction process is fragmented and inefficient. The outer protective layer, insulation layer and phase change energy storage layer often need to be poured in multiple stages. After each pour, it is necessary to wait for initial setting or install temporary partition templates. The construction cycle is long and the quality of interlayer bonding is difficult to guarantee, which can easily lead to cold joints or debonding.
[0003] 2. Difficulty in vibration and thickness control For thermal insulation materials containing aerogels, vacuum insulation panels, or other brittle and easily damaged materials, as well as energy storage layers containing microencapsulated phase change materials, traditional vibratory rods or immersion vibrators can easily damage the material structure, leading to a decrease in thermal insulation or energy storage performance. Furthermore, the thickness of each layer relies on manual positioning and adjustment, resulting in poor precision and difficulty in meeting the uniformity requirements of the design.
[0004] 3. Lack of integrated pouring and regulating devices Existing equipment cannot simultaneously complete precise layered casting of multiple materials and thicknesses, lacks a protection mechanism for phase change materials, and cannot dynamically adjust the vibration depth and angle during the casting process to meet the compaction requirements of different layer thicknesses. To address the aforementioned issues, this application proposes a construction method and apparatus for a high-efficiency thermal insulation composite wall for building envelopes.

[0026] Reference Figure 2 The adjustment mechanism 7 also includes multiple fixing boxes 78. The rotating rod 72 is fixedly installed on two mounting plates 53 on the same side, and is rotatably connected to a fixed box 78 on the same mounting plate 53.

At the same time, the setting of the fixed box 78 can stabilize the rotation state of the rotating rod 72 and isolate and protect the worm gears 74 and worm wheels 75.
[0027] Working principle: During operation, different building phase change materials are placed between two partitions 2 inside the casting box 1. During casting, the drive motor 9 is switched on, and the output shaft of the drive motor 9 drives the active rod 11 to rotate. The active rod 11 drives the rotating roller 15 to rotate. The rotating roller 15 is slidably connected to the slider 17 through the cam groove 16, thereby driving the drive plate 12 to move up and down. The drive plate 12 is slidably connected to the inclined hole 13 through the movable shaft 14, thereby driving the force plate 10 and the push plate 54 to move laterally. In turn, the mounting plate 53 drives the fixed frame 51 and the vibrating bar 52 to quickly vibrate the casting material in the casting box 1. When it is necessary to adjust the vibration height, the output shaft of the adjusting motor 73 drives the two rotating rods 72 to rotate simultaneously through the meshing of the two sprockets 76 and the chain 77. The rotating rod 72, through the meshing of the worm gear 74 and the worm wheel 75, drives the positioning shaft 71 to change angle, which in turn drives the fixed frame 51 to change angle. This allows for vibration compaction of the pouring material to different thicknesses. At the same time, the fixed box 78 stabilizes the rotation of the rotating rod 72 and isolates and protects the worm gear 74 and the worm wheel 75. When it is necessary to adjust the pouring thickness, the solenoid valve 66 controls the four hydraulic cylinders 62. The hydraulic cylinders 62 drive the top block 63 to move through the piston. The top block 63 is rotatably connected to the guide block 65, which drives the guide block 65 to move up and down. The guide block 65 is slidably connected to the guide plate 61, which drives the guide plate 61 to change angle, thereby adjusting the pouring thickness between the two guide plates 61.
