Description

Technical Field

[0001] The present application relates to the field of prefabricated walls, and in particular to a novel assembled lightweight composite laminate floor slab. Background Art

[0002] At present, in the process of construction industrialization, compared with the traditional casting method, prefabricated buildings have improved the construction site environment and are more convenient for construction workers to build buildings. At the same time, they effectively shorten the construction period. Therefore, prefabricated buildings have developed rapidly.

[0003] As an important part of prefabricated buildings, prefabricated composite floor slabs have the advantages of both cast-in-place slabs and prefabricated slabs, so they are widely used in prefabricated houses. Existing composite floor slabs are made by stacking prefabricated slabs and cast-in-place reinforced concrete layers. The cast-in-place reinforced concrete layer is composed of steel bars and poured concrete. Horizontal pipelines can be laid in advance between the steel bars to realize the in-wall layout of the pipelines.

[0004] Regarding the above-mentioned related technologies, since the existing prefabricated composite floor slabs use a lot of concrete, the cost of transportation, hoisting and installation of the finished products is relatively high, and concrete also has disadvantages such as poor sound insulation and no heat preservation. Utility Model Content

[0005] In order to ensure the strength of composite floor slabs while taking into account thermal insulation and sound insulation, the present application provides a new type of assembled lightweight composite composite composite floor slab.

[0006] The present application provides a novel assembled lightweight composite laminate floor slab, which adopts the following technical solution:

[0007] A novel assembled lightweight composite laminated floor comprises a base plate, wherein a lightweight concrete layer is provided on the upper side of the base plate, a steel bar layer is provided inside the lightweight concrete layer, and a dense concrete layer is provided on the upper side of the lightweight concrete layer.

[0008] By adopting the above technical solution, a lightweight concrete layer is set on the floor, and a steel bar layer is buried inside the concrete layer. A dense concrete layer is set on the upper side of the lightweight concrete layer. The overall weight of the lightweight concrete layer is low and has a good sound insulation effect. The steel bar layer and the dense concrete layer effectively strengthen the overall structure, thereby effectively ensuring the strength of the composite floor while taking into account insulation and sound insulation.

[0009] Optionally, the lightweight concrete layer includes a plurality of giant lightweight concrete blocks, and the giant lightweight concrete blocks are evenly arranged along the length and width directions of the base plate.

[0010] By adopting the above technical solution, by using the giant lightweight concrete blocks as the main components of the lightweight concrete layer, the giant lightweight concrete blocks complete the manufacture of the lightweight concrete layer while ensuring the corresponding thermal insulation and sound insulation effects.

[0011] Optionally, a U-shaped groove is provided in the lightweight concrete layer, the U-shaped groove is located between adjacent giant lightweight concrete blocks, and the U-shaped groove is used for laying a steel bar layer.

[0012] By adopting the above technical solution, a U-shaped groove is started in the giant lightweight concrete layer to facilitate laying of the steel bar layer in the U-shaped groove, and the U-shaped groove is also convenient for laying pipes and wires in advance. The remaining space in the U-shaped groove is filled by pouring a dense concrete layer, thereby increasing the contact area between the lightweight concrete layer and the dense concrete layer, and effectively strengthening the connection strength between the lightweight concrete layer and the dense concrete layer.

[0013] Optionally, a fixing pin is provided in the U-shaped groove, the fixing pin is located at the bottom of the U-shaped groove, and the fixing pin extends along the lightweight concrete layer. There are a plurality of fixing pins.

[0014] By adopting the above technical solution, a fixing pin is arranged in the U-shaped groove to facilitate positioning when pouring in the dense concrete layer and positioning of the precast panels when installing, which effectively facilitates pouring of the dense concrete layer.

[0015] Optionally, the steel bar layer includes transverse steel bars and longitudinal steel bars, the longitudinal steel bars are arranged along the length direction of the bottom plate, the transverse steel bars are arranged along the width direction of the bottom plate, and the transverse steel bars are provided with avoidance portions, which are located at the connection between the transverse steel bars and the longitudinal steel bars.

[0016] By adopting the above technical scheme, compared with simply setting the steel bars in one direction, the steel bars are divided into transverse steel bars and longitudinal steel bars and installed and set in the transverse and longitudinal directions, so that the steel bar layer forms a steel mesh composed of transverse steel bars and longitudinal steel bars. By arranging an avoidance portion on the transverse steel bars, the connection and installation relationship between the transverse steel bars and the longitudinal steel bars is facilitated, thereby effectively enhancing the strength of the steel bar layer.

[0017] Optionally, both the longitudinal steel bars and the transverse steel bars are arranged in the U-shaped groove, two longitudinal steel bars are arranged in the U-shaped groove for placing the longitudinal steel bars, and one transverse steel bar is arranged in the U-shaped groove for placing the transverse steel bars.

[0018] By adopting the above technical solution, since the width of the composite composite floor is relatively narrow, only one horizontal steel bar is installed in each horizontal U-shaped groove. By arranging two longitudinal steel bars in the U-shaped groove, the problem of insufficient strength of the steel bar layer along the length direction of the floor due to the excessive length of the composite composite floor is effectively solved.

[0019] Optionally, the base plate is a thick cement fireproof board.

[0020] By adopting the above technical solution, cement fireproof board is used as the bottom plate. Compared with the traditional bottom plate, cement fireproof board has better fire prevention and fire source isolation, so that when the wall requires higher fire protection requirements, the composite composite floor can be effectively installed and used, effectively expanding the scope of application. Optionally, the dense concrete layer is provided with connecting parts on both sides of the bottom plate in the width direction, and the connecting parts wrap the bottom plate and the two sides of the lightweight concrete layer in the width direction, and the connecting parts are used for the installation of the composite composite floor.

[0021] By adopting the above technical solution, when pouring the dense concrete layer, the connection parts are poured on both sides of the dense concrete layer close to the width direction of the bottom plate, so that the construction workers can position and guide the composite composite floor when installing it on site.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. A lightweight concrete layer is set on the floor, and a steel bar layer is buried inside the concrete layer. A dense concrete layer is set on the upper side of the lightweight concrete layer. The lightweight concrete layer has a lower overall mass and has a better sound insulation effect. The steel bar layer and the dense concrete layer effectively strengthen the overall structure, thereby effectively ensuring the strength of the composite floor while taking into account both thermal insulation and sound insulation;

[0024] 2. Start a U-shaped groove in the giant lightweight concrete layer to facilitate laying the steel bar layer in the U-shaped groove, and the U-shaped groove is also convenient for laying pipes and wires in advance. Fill the remaining space in the U-shaped groove by pouring a dense concrete layer to increase the contact area between the lightweight concrete layer and the dense concrete layer, effectively strengthening the connection strength between the lightweight concrete layer and the dense concrete layer.

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] The embodiment of the present application discloses a novel assembled lightweight composite composite floor slab.

[0031] Reference Figure 1 A novel assembled lightweight composite composite floor slab comprises a bottom plate 1, a lightweight concrete layer 2 is arranged on the upper side of the bottom plate 1, a steel bar layer 3 is arranged inside the lightweight concrete layer 2, and a dense concrete layer 4 is arranged on the upper side of the lightweight concrete layer 2. A lightweight concrete layer 2 is arranged on the floor, and a steel bar layer 3 is buried inside the concrete layer, and a dense concrete layer 4 is arranged on the upper side of the lightweight concrete layer 2. The lightweight concrete layer 2 has a low overall mass and has a good sound insulation effect. The steel bar layer 3 and the dense concrete layer 4 effectively enhance the overall structure, thereby effectively ensuring the strength of the composite floor slab while taking into account both thermal insulation and sound insulation.

[0032] Reference Figure 1 In order to effectively improve the fireproof performance of the whole structure. In this embodiment, the bottom plate 1 is a thick cement fireproof board. Compared with the traditional bottom plate 1, the cement fireproof board is used as the bottom plate 1. The cement fireproof board has a better fireproof and fire source isolation method, so that when the wall requires higher fireproof requirements, the composite composite floor slab can be effectively installed and used, which expands the application scope of the composite composite floor slab.

[0033] Reference Figure 1 In order to facilitate the subsequent installation and adjustment of the composite composite floor slab by the operators, the dense concrete layer 4 is provided with connecting parts on both sides of the width direction of the bottom plate 1, and the connecting parts wrap the bottom plate 1 and the two sides of the width direction of the lightweight concrete layer 2, and the connecting parts are used for the installation of the composite composite floor slab. When pouring the dense concrete layer 4, the connecting parts are poured on both sides of the dense concrete layer 4 close to the width direction of the bottom plate 1, so that the construction personnel can position and guide the composite composite floor slab when installing it on site.

[0034] Reference Figure 2 and Figure 3 The installation and setting method of the lightweight concrete layer 2 is that the lightweight concrete layer 2 includes a plurality of giant lightweight concrete blocks 21, and the giant lightweight concrete blocks 21 are evenly arranged along the length and width direction of the bottom plate 1. By using the giant lightweight concrete blocks 21 as the main component of the lightweight concrete layer 2, while ensuring the corresponding heat preservation and sound insulation effects, the giant lightweight concrete blocks 21 complete the installation and setting of the lightweight concrete layer 2.

[0035] Reference Figure 1 and Figure 3, in order to facilitate the laying and placement of the steel bar layer 3. A U-shaped groove 23 is provided in the lightweight concrete layer 2, and the U-shaped groove 23 is located between adjacent giant lightweight concrete blocks 21. The U-shaped groove 23 is used to lay the steel bar layer 3. The U-shaped groove 23 is started in the giant lightweight concrete layer to facilitate the laying of the steel bar layer 3 in the U-shaped groove 23, and the U-shaped groove 23 is also convenient for laying pipelines and wires in advance, so as to facilitate the routing and installation of pipelines in the later stage. The remaining space in the U-shaped groove 23 is filled by pouring a dense concrete layer, thereby increasing the contact area between the lightweight concrete layer 2 and the dense concrete layer 4, and effectively strengthening the connection strength between the lightweight concrete layer 2 and the dense concrete layer 4.

[0036] Reference Figure 1 and Figure 3 When pouring the dense concrete layer 4, the mold needs to be positioned and installed. A fixing pin 22 is provided in the U-shaped groove 23, and the fixing pin 22 is located at the bottom of the U-shaped groove 23. The fixing pin 22 extends along the lightweight concrete layer 2, and a plurality of fixing pins 22 are provided. The fixing pin 22 is provided in the U-shaped groove 23 to facilitate positioning when pouring the dense concrete layer 4 and positioning the precast panels when installing, so as to facilitate pouring the dense concrete layer 4.

[0037] Reference Figure 2 and Figure 3 , in order to strengthen and connect the overall strength. The steel bar layer 3 includes transverse steel bars 32 and longitudinal steel bars 31. The longitudinal steel bars 31 are arranged along the length direction of the bottom plate 1, and the transverse steel bars 32 are arranged along the width direction of the bottom plate 1. The transverse steel bars 32 are provided with an avoidance portion, and the avoidance portion is located at the connection between the transverse steel bars 32 and the longitudinal steel bars 31. Compared with simply arranging steel bars in one direction, the steel bars are divided into transverse steel bars 32 and longitudinal steel bars 31 and are installed and arranged transversely and longitudinally, so that the steel bar layer 3 forms a steel mesh composed of transverse steel bars 32 and longitudinal steel bars 31. By arranging the avoidance portion on the transverse steel bars 32, the connection and installation relationship between the transverse steel bars 32 and the longitudinal steel bars 31 is facilitated, and the connection strength of the steel bar layer 3 is strengthened.

[0038] Reference Figure 2 and Figure 3, usually the length of the composite composite floor is long, and it is usually installed and used vertically in the length direction, so more support and reinforcement are required in the length direction compared with the width direction. Therefore, the longitudinal steel bars 31 and the transverse steel bars 32 are both arranged in the U-shaped groove 23, and two longitudinal steel bars 31 are arranged in the U-shaped groove 23 for placing the longitudinal steel bars 31, and one transverse steel bar 32 is arranged in the U-shaped groove 23 for placing the transverse steel bars 32. Since the width of the composite composite floor is relatively narrow, only one transverse steel bar 32 is installed in each transverse U-shaped groove 23. By arranging two longitudinal steel bars 31 in the U-shaped groove 23, the problem of insufficient strength of the steel bar layer 3 along the length direction of the floor caused by the excessive length of the composite composite floor is solved.

[0039] Reference Figure 2 It may happen that due to the required width being large, two parallel bottom plates 1 are provided. When installing the longitudinal steel bars 31 between the two bottom plates 1, three steel bars can be placed to ensure a stable connection between the two bottom plates 1.

[0040] The implementation principle of a novel assembled lightweight composite laminated floor in the embodiment of the present application is as follows: by arranging a partial lightweight concrete layer 2 in the composite laminated floor to replace the traditional dense concrete layer 4, the overall weight is effectively reduced. Compared with the dense concrete layer 4, the lightweight concrete layer 2 also has better sound insulation and thermal insulation effects, which effectively improves the sound insulation and thermal insulation effects of the composite laminated floor. By adding a thick cement fireproof board to the composite laminated floor, the composite laminated floor has better fire insulation ability, so that the composite laminated floor can be used in walls with relevant fire insulation requirements.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
