Description

Technical Field

[0001] This utility model relates to the field of precast wall components, and in particular to a precast reinforced concrete wall sound insulation and heat insulation component. Background Technology

[0002] Reinforced concrete slab components, also known as wall panels, are prefabricated concrete panels manufactured in prefabrication plants or on construction sites for use in building assembly. Using prefabricated concrete wall panels to construct prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet work, save on-site labor, overcome seasonal influences, and shorten the construction cycle.

[0003] The existing type of precast concrete house with heat insulation and sound insulation (Announcement No.: CN215802645U) has at least the following drawbacks: the sound insulation effect is poor when only heat insulation boards are used. When the distance to the sound source is close, the sound waves are directly transmitted to the interior through the wall, which cannot effectively insulate the sound. In addition, the inner side of the wall is made of smooth and thin material for ease of use, which makes it easy to break, crack and age, affecting the sound insulation and heat insulation effect. Replacing it is also very troublesome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a precast reinforced concrete wall sound and heat insulation component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precast reinforced concrete wall sound and heat insulation component includes a main wall, in which connecting rods are provided, the connecting rods being arranged horizontally at equal intervals, and annular ribs being provided on the outer side of the connecting rods, the annular ribs vertically surrounding the outer side of the connecting rods, the connecting rods being welded to the inner side of the annular ribs, an mounting block being fixedly installed on the inner side of the connecting rods, a heat insulation layer being provided on the inner side wall of the main wall, the heat insulation layer being fixed to the main wall, the heat insulation layer having holes for fitting onto the mounting block, and a fiberboard being provided on the outer side of the heat insulation layer.

[0007] As a further embodiment of this utility model, an installation groove is provided on the fiberboard at the position corresponding to the installation block, a threaded rod is provided in the installation groove, the threaded rod can move in the installation groove, and a gasket is provided between the threaded rod and the installation groove, the gasket being preferably a sound insulation sheet.

[0008] As a further embodiment of this utility model, diffuse spheres are evenly spaced on the outer side wall of the main wall. The diffuse spheres are hemispherical, and a connecting block is fixedly installed on the back of the diffuse sphere. The tail of the connecting block is fixedly welded to the side wall of the connecting rod.

[0010] As a further embodiment of this utility model, the connecting rod has a hollow structure inside, and sound insulation cotton is provided on the connecting rod, with the sound insulation cotton filling the inside of the connecting rod.

[0011] As a further embodiment of this utility model, the left side of the connecting rod extends to the outside of the main wall, and a connecting groove is provided on the right side of the main wall corresponding to the position of the connecting rod, so that the connecting rod can be inserted into the connecting groove.

[0012] As a further embodiment of this utility model, the main wall and the left and right sides of the insulation layer are staggered, and the insulation layer can shield the connection between the main wall and the insulation layer.

[0013] As a further embodiment of this invention, the heat insulation layer is preferably made of foamed cement board.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the two main walls can be joined together by inserting the connecting rod into the connecting groove. The heat insulation layer on the main wall can block the connection point of the main wall, preventing sound from passing through the connection point. At the same time, the spherical diffuser on the outside of the main wall can reflect and diffuse some of the sound. Then, the annular ribs and connecting rod can absorb most of the sound on the main wall. The heat insulation layer can also absorb some of the sound. Finally, the fiberboard can reflect the sound from the outside, thereby achieving effective sound insulation while providing heat insulation.

[0016] 2. In this utility model, the threaded rod can be removed from the mounting block by rotating the threaded rod, and then the gasket in the mounting groove can be removed. At this time, the fiberboard can be removed from the insulation layer and replaced. After replacing the fiberboard, the threaded rod can be fixed to the mounting block to complete the replacement, thereby achieving the effect of easy maintenance and convenient replacement of the interior wall surface.
