Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated walls, in particular to a novel building energy-saving and sound-insulating prefabricated wall. Background Art

[0002] Nowadays, with the continuous development of society and the continuous construction of cities, in order to save construction time and ensure quality, prefabricated buildings are gradually being widely used. In the process of prefabricated building construction, in order to ensure construction efficiency and convenience, building energy-saving and sound-insulating prefabricated walls are usually used for construction. The existing building energy-saving and sound-insulating prefabricated walls are usually composed of concrete walls, insulation layers, sound insulation layers and structural layers.

[0003] For example: The utility model with application number CN202321306044.8 discloses a prefabricated environmentally friendly and energy-saving wall for a building. Specifically, the utility model discloses a prefabricated environmentally friendly and energy-saving wall for a building, which relates to the technical field of energy-saving walls and solves the technical problem that the existing technology cannot actively insulate and recycle energy. It includes a main wall panel, which is a rectangular plate body. The front wall of the main wall panel is provided with an installation groove, which is a rectangular groove. A light energy collection structure is installed in the main wall panel, a heat insulation structure is installed in the main wall panel, and a sound insulation structure is provided in the main wall panel. The utility model is charged by solar panels to provide electricity for the battery, protects the solar panel through a transparent panel to reduce the external erosion of the solar panel, circulates cold water or hot water through a heat pipe to provide internal heating or cooling, and forms isolation from the external temperature. By filling with foam and sound insulation tiles and cavities, the internal sound transmission is reduced and absorbed, and the wall structure strength is increased by reinforcing rods.

[0004] However, during the transportation of energy-saving and sound-insulating prefabricated walls for buildings, the prefabricated parts are prone to shaking in the carriage due to factors such as road bumps and vehicle start-stops, causing their edges and corners to frequently contact the metal frame or adjacent components of the carriage, and then be damaged due to scratches and collisions. This will not only damage the functional performance of the wall, but also increase the difficulty of handling during the construction process, affecting the subsequent installation and use of the wall. Summary of the Invention

[0005] In view of this, the present invention provides a novel energy-saving and sound-insulating prefabricated wall for building, which has a first splicing block and a second splicing block for protecting the edges and corners during transportation. During transportation of the prefabricated wall, the second splicing block and the first splicing block can be flipped so that the inclined surface of the second splicing block fits with the inclined surface of the first splicing block to form an L-shaped block, so that the L-shaped block covers the right-angled corners of the prefabricated wall, thereby preventing the corners of the prefabricated wall from being damaged during transportation. When the inclined surface of the second splicing block fits with the inclined surface of the first splicing block, the splicing plug-in of the first splicing block will be inserted into the splicing slot of the second splicing block to form a mechanical bite structure. After the splicing plug-in and the splicing slot are engaged, the second splicing block and the first splicing block form a rigid whole, which will not be dispersed or shifted due to shaking during transportation. At the same time, the setting of the inclined surfaces of the second splicing block and the first splicing block will generate lateral extrusion force when under pressure, so that the splicing plug-in and the splicing slot are pressed tighter and tighter, thereby achieving physical locking.

[0016] Beneficial effects

[0017] During the transportation of the present invention, it is only necessary to press the toggle slot to make the control slide drive the locking plug to move. As the locking plug moves, it will be stored in the auxiliary rotating seat. Only then can the limit of the auxiliary rotating seat be released. At this time, the auxiliary rotating seat can be rotated to release the limit of the first splicing block and the second splicing block. Then, the second splicing block and the first splicing block are flipped over, so that the inclined surface of the second splicing block and the inclined surface of the first splicing block are fitted together to form an L-shaped block, so that the L-shaped block covers the right angle of the prefabricated wall. Corners, to prevent vehicle bumps, sudden braking or loading and unloading collisions during transportation, the L-shaped block can disperse the impact force to the L-shaped block, avoiding the impact force directly acting on the fragile parts of the wall corners. At the same time, through the auxiliary rubber block, when the prefabricated wall collides with the transport carriage or other components, the elastic deformation of the rubber block will absorb the impact energy, reduce the damage to the corners caused by hard collisions, ensure the integrity of the wall, reduce the overall performance degradation and appearance defects of the wall caused by damage to the corners, and effectively improve the practicality of the building energy-saving and sound-insulating prefabricated wall.

[0018] When the first splicing block and the second splicing block are stored back into the first receiving groove and the second receiving groove, the inclined surfaces of the first splicing block and the second splicing block can be filled by setting the limit block, so that the first receiving groove and the second receiving groove are completely filled, so that the wall will not be concave after the splicing is completed, ensuring the flatness and beauty of the surface of the building's energy-saving and sound-insulating prefabricated wall, and further improving the practicality of the building's energy-saving and sound-insulating prefabricated wall.

[0019] The sound insulation functional layer forms a moderate curved surface with a curvature radius of 100mm-300mm, which can effectively diffuse the human voice frequency band and environmental low-frequency noise. At the same time, when the wall is vibrated or deformed, the elastic deformation of the curved surface can buffer the stress. The trapezoidal slope of the thermal insulation interlayer will form a continuous heat flow reflection interface, forcing the heat to be reflected multiple times in the air layer between the panels rather than conducted in a straight line, thereby improving the thermal insulation effect of the prefabricated wall and effectively improving the applicability of the building energy-saving and sound insulation prefabricated wall.

[0041] Specific usage and function of this embodiment: In the present invention, the provision of the waterproof coiled material layer 101 can reduce the intrusion of water vapor, the provision of the sound insulation functional layer 102 can enhance the sound insulation effect of the prefabricated wall, the provision of the thermal insulation interlayer 103 can enhance the thermal insulation effect of the prefabricated wall, and the provision of the steel skeleton layer 104 can enhance the overall strength of the prefabricated wall. During the transportation of the prefabricated wall, the second splicing block 113 and the first splicing block 112 can be flipped over so that the inclined surface of the second splicing block 113 and the inclined surface of the first splicing block 112 fit together to form an L-shaped block, so that the L-shaped block covers the right-angled corners of the prefabricated wall to prevent the corners of the prefabricated wall from being damaged during transportation. When the inclined surface of 3 fits with the inclined surface of the first splicing block 112, the splicing plug-in 117 of the first splicing block 112 will be inserted into the splicing slot 116 of the second splicing block 113, forming a mechanical bite structure. After the splicing plug-in 117 and the splicing slot 116 are engaged, the second splicing block 113 and the first splicing block 112 form a rigid whole, which will not be scattered or shifted due to shaking during transportation. At the same time, the setting of the inclined surfaces of the second splicing block 113 and the first splicing block 112 and the design of the inclined surfaces decompose the impact force into lateral friction force and longitudinal pressure, and realize self-locking through the metal contact surface with a friction coefficient of 0.8, so that the splicing plug-in 117 and the splicing slot 116 are pressed tighter and tighter, realizing physical locking. At the same time, the mechanical bite structure can also be easily disassembled and assembled. During the splicing process of the second splicing block 113 and the first splicing block 112, the auxiliary rubber block 114 will also be spliced. The auxiliary rubber block 114 is spliced ​​into an L-shaped rubber seat by setting the inclined surface of the auxiliary rubber block 114. The L-shaped rubber seat can provide buffer protection for the prefabricated wall. The first splicing block 112 and the second splicing block 113 in the first receiving groove 108 and the second receiving groove 109 can be limited by setting the limiting block 118. At the same time, the limiting block 118 can fill the inclined surfaces of the first splicing block 112 and the second splicing block 113, so that the first receiving groove 108 and the second receiving groove 109 are completely filled, so that there will be no gaps in the wall after the splicing is completed, ensuring the splicing of the wall. The auxiliary rotating seat 115 is fixed with the locking plug 120 in the initial state and fixed with the position of the auxiliary rotating seat 115, thereby ensuring the limiting effect of the limit block 118 on the first splicing block 112 and the second splicing block 113. During transportation, it is only necessary to press the toggle groove 122 to make the control slide 119 slide in the auxiliary rotating seat 115 and squeeze the auxiliary spring 121. As the control slide 119 slides, the locking plug 120 is driven to move. As the locking plug 120 moves, it is retracted into the auxiliary rotating seat 115. Only then can the limiting of the auxiliary rotating seat 115 be released, and the auxiliary rotating seat 115 can be rotated to release the limiting of the first splicing block 112 and the second splicing block 113.At this time, the first splicing block 112 and the second splicing block 113 can be rotated to facilitate subsequent splicing. The first receiving groove 108 and the second receiving groove 109 are both coated with epoxy resin for waterproof and moisture-proof treatment. Metal reinforcement frames are installed at the edges of the first receiving groove 108 and the second receiving groove 109 to prevent cracking. The contact surfaces of the first splicing block 112, the second splicing block 113 and the limit block 118 are all provided with elastic sealing strips, which are squeezed and sealed during storage. In the process of splicing the prefabricated wall, the positioning plug 105 on the left side of the concrete base 1 is inserted into the positioning slot 106 on the right side of the concrete base 1 of another prefabricated wall. The prefabricated wall can be positioned by cooperating with the positioning plug 105 and the positioning slot 106. When the positioning block 105 is inserted into the positioning slot 106, the positioning slot 106 will squeeze the locking block 123. As the locking block 123 is squeezed, it will slide in the positioning block 105 and squeeze the fixing spring 124. When the positioning block 105 is fully inserted into the positioning slot 106, the locking slot 107 is aligned with the locking block 123. At this time, the locking block 123 will reset with the rebound of the fixing spring 124, so that the locking block 123 is inserted into the locking slot 107, which assists in fixing the prefabricated wall and ensures the stability of the prefabricated wall during the splicing process. The auxiliary rubber block 114 is made of EPDM rubber with a Shore hardness of 60A, a thickness of 10mm, and a rebound rate of ≥80%. The material of the splicing block 117 and the splicing slot 116 are both Q235B steel.

[0042] Example 2: Based on Example 1, please refer to Figures 1 to 10 As shown, it includes: a sound insulation functional layer 102 and a thermal insulation interlayer 103. The sound insulation functional layer 102 is composed of multiple groups of arc-shaped plate structures made of flexible sound insulation materials, and the multiple groups of arc-shaped plate structures are arranged in parallel along the sound propagation direction; the arc curvature radius of the arc-shaped plate structure is 100mm-300mm, and the central angle thereof is 90 degrees-180 degrees.

[0043] The thermal insulation interlayer 103 is composed of a plurality of groups of trapezoidal plate structures made of rock wool boards, and the plurality of groups of trapezoidal plate structures are arranged in a linear array along the height direction of the wall.

[0044] Specific usage and function of this embodiment: In the present invention, a moderate curved surface curvature is formed by a curvature radius of 100mm-300mm, which can produce effective diffuse reflection of the human voice frequency band and environmental low-frequency noise. At the same time, when the wall is vibrated or deformed, the elastic deformation of the curved surface can buffer the stress. The trapezoidal slope will form a continuous heat flow reflection interface, forcing the heat to be reflected multiple times in the air layer between the plates rather than conducted in a straight line, thereby improving the thermal insulation effect of the prefabricated wall.
