Description

Technical Field

[0001] The present application relates to the technical field of concrete panels, and in particular to a high-strength thermal insulation aerated concrete panel. Background Art

[0002] Concrete slab is an important building material. There is detailed information on its characteristics, classification, uses and production process. Concrete slab is cast after mixing cement, stone, sand and water. It has high durability and can withstand greater pressure. It is suitable for various construction scenarios. Concrete slab has strong resistance to chemical substances and is not easily corroded.

[0003] A patent with publication number CN220247360U discloses a precast concrete panel, including a first concrete panel and a second concrete panel formed in one piece, the first concrete panel is located on the upper side of the second concrete panel and the lower surface of the first concrete panel is smaller than the lower surface of the second concrete panel, and the first concrete panel and the second concrete panel are provided with a step surface in at least one direction. The above patent can provide users with a method for increasing the contact area between the poured concrete and the precast concrete panel, thereby strengthening the connection strength between the precast concrete panel and the subsequently poured concrete, and improving the overall strength of the formed prefabricated reinforced concrete structure.

[0004] However, the above technical solution has the following defects:

[0005] (1) In the process of producing concrete slabs in the prior art, since concrete is only cast by mixing cement, stone, sand and water, the gravity density of the concrete slab is relatively high, generally 2000-2800 kg / m 3 , so the overall weight is large, which increases the difficulty and cost of transportation and installation, especially in the construction of high-rise buildings or large-span structures;

[0006] (2) The concrete slabs in the prior art have high thermal conductivity and poor thermal insulation. Ordinary reinforced concrete has high thermal conductivity and poor thermal insulation performance, which may lead to poor insulation effect of the building in winter and increase energy consumption. Utility Model Content

[0007] One purpose of the present application is to reduce the weight of the concrete slab while ensuring the strength of the concrete slab so that it can better withstand pressure.

[0008] To achieve the above purpose, the technical solution adopted in the present application is: a high-strength heat-insulating aerated concrete board, comprising an upper concrete board, a lower concrete board is fixedly connected to the lower surface of the upper concrete board, a plurality of positioning grooves are opened between the upper concrete board and the lower concrete board, and a positioning frame is fixedly connected to each positioning groove;

[0009] and a plurality of first slots formed on the upper surface of the upper concrete slab, wherein a second protrusion is fixedly connected between every two first slots on the upper surface of the upper concrete slab;

[0010] A plurality of first protrusions are arranged on the lower surface of the lower concrete slab, and a second groove is arranged between every two of the first protrusions.

[0011] Preferably, a plurality of first protrusions on the lower surface of one of the lower concrete slabs are plugged into a plurality of first grooves on the upper surface of another upper concrete slab.

[0012] Preferably, each positioning frame is fixedly connected with two steel bars in opposite directions.

[0013] Preferably, a plurality of positioning blocks are fixedly connected to the upper surface of the lower concrete slab, each of the positioning blocks is fixedly connected between two positioning frames, and a penetrating fixing hole is formed on the surface of each of the positioning blocks.

[0014] Preferably, a slot is provided on one side of the upper concrete slab, and a slide plate is slidably connected in the slot.

[0015] Preferably, two sliding blocks are fixedly connected to the lower surface of the slide plate, and sliding grooves are provided at positions of the upper concrete slab corresponding to the two sliding blocks, and the slide plate can slide along the sliding grooves through the sliding blocks.

[0016] Preferably, a slot is provided on one side of the lower concrete slab, an insert block is inserted into the slot, and the insert block is made of waterproof material.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] 1. A positioning frame is fixedly connected in each positioning groove of the lower concrete slab. The positioning frame is made of silicone foam and can achieve high and low temperature resistance, high flame retardancy and other characteristics. Then the upper concrete slab and the lower concrete slab are spliced ​​together, and concrete is poured into the production frame. Then the concrete will enter the positioning frame and be fixed between the upper concrete slab and the lower concrete slab. Because the silicone foam positioning frame has a lighter material, it can reduce the mass of the concrete slab to a certain extent, thereby achieving the effect of easy transportation and better heat insulation effect.

[0019] 2. A slot is opened on one side of the upper concrete slab, and then a slide plate is slidably arranged in the slot. The slide plate can be replaced according to the customized concrete slab. For example, if a concrete slab with good sound insulation needs to be replaced, the slide plate can be replaced with a slide plate with good sound insulation material. When a concrete slab with better heat insulation needs to be replaced, the slide plate can be replaced with a slide plate with good heat insulation material before pouring. Then a slot is opened inside the lower concrete slab, and an insert is inserted in the slot. The insert is made of waterproof material, so that the concrete slab has a better waterproof effect.

[0030] The prior art has the following defects:

[0031] (1) In the process of producing concrete slabs in the prior art, since concrete is only cast by mixing cement, stone, sand and water, the gravity density of the concrete slab is relatively high, generally 2000-2800 kg / m 3 , so the overall weight is large, which increases the difficulty and cost of transportation and installation, especially in the construction of high-rise buildings or large-span structures.

[0032] (2) The concrete slabs in the prior art have high thermal conductivity and poor thermal insulation. Ordinary reinforced concrete has high thermal conductivity and poor thermal insulation performance, which may lead to poor thermal insulation effect of the building in winter and increase energy consumption.

[0033] As an improvement, Figures 1 to 5 As shown, the preferred embodiments of the present application are:

[0034] A high-strength heat-insulating aerated concrete panel comprises an upper concrete panel 1, a lower concrete panel 11 being fixedly connected to the lower surface of the upper concrete panel 1, a plurality of positioning grooves 15 being provided between the upper concrete panel 1 and the lower concrete panel 11, a positioning frame 14 being fixedly connected to each positioning groove 15; a plurality of first slot bodies 12 being provided on the upper surface of the upper concrete panel 1, a second protrusion 110 being fixedly connected between every two first slot bodies 12 on the upper surface of the upper concrete panel 1; and a plurality of first protrusions 13 being provided on the lower surface of the lower concrete panel 11, a second slot body 111 being provided between every two first protrusions 13.

[0035] Specifically, in the process of producing concrete slabs in the prior art, since concrete is only cast by mixing cement, stone, sand and water, the gravity density of the concrete slab is relatively high, generally 2000-2800kg / m 3 , so the overall weight is large, which increases the difficulty and cost of transportation and installation, especially in the construction of high-rise buildings or large-span structures;

[0036] Therefore, the utility model can reduce the weight of the concrete slab through the corresponding structure while ensuring the strength of the concrete slab. First, when the concrete slab is made, a positioning frame 14 is fixedly connected in each positioning groove 15 of the lower concrete slab 11. The positioning frame 14 is made of silicone foam and can achieve high and low temperature resistance, high flame retardancy and other characteristics. Then, the upper concrete slab 1 and the lower concrete slab 11 are spliced ​​together, and concrete is poured into the making frame. Then, the concrete will enter the positioning frame 14, so as to be fixed between the upper concrete slab 1 and the lower concrete slab 11. Because the positioning frame 14 made of silicone foam has a lighter material, it can reduce the mass of the concrete slab to a certain extent, thereby achieving the effect of facilitating transportation and having a better heat insulation effect.

[0037] The concrete slab has a high gravity density, generally 2000-2800kg / m, because the concrete is only cast by mixing cement, stone, sand and water. 3 , so the overall weight is large, which increases the difficulty and cost of transportation and installation.

[0038] like Figures 2 to 4 As shown, in this embodiment, a plurality of first protrusions 13 on the lower surface of one lower concrete slab 11 are plugged into a plurality of first slots 12 on the upper surface of another upper concrete slab 1 .

[0039] Specifically, by fixing a plurality of first protrusions 13 on the lower surface of the lower concrete slab 11, when a larger concrete slab needs to be made, the plurality of first protrusions 13 on the lower surface of one of the lower concrete slabs 11 are inserted into a plurality of first grooves 12 on the upper surface of another upper concrete slab 1, so that a larger concrete slab frame can be obtained, and at the same time, the strength of the synthesized concrete slab can be ensured, thereby achieving a better use effect, being more practical, adapting to more attempts to produce concrete slabs, and expanding the size types of concrete slabs.

[0040] like Figure 5 As shown, in this embodiment, two steel bars 116 in opposite directions are fixedly connected in each positioning frame 14 .

[0041] Specifically, by fixing two steel frames 116 in opposite directions in each positioning frame 14, the steel frames 116 can provide certain support to the positioning frame 14, and when concrete is poured into the positioning frame 14, the steel frames 116 can improve the compressive strength of the concrete slab, and each steel frame 116 is triangular.

[0042] like Figure 2 As shown, in this embodiment, a plurality of positioning blocks 18 are fixedly connected to the upper surface of the lower concrete slab 11 , each positioning block 18 is fixedly connected between two positioning frames 14 , and a penetrating fixing hole 19 is formed on the surface of each positioning block 18 .

[0043] Specifically, a positioning block 18 is fixed between every two positioning frames 14, and a fixing hole 19 is opened on the side of the positioning block 18. In this way, after the concrete is poured into the positioning frame 14, the entire upper concrete slab 1 and the lower concrete slab 11 can form a loop, thereby making the concrete pouring effect better and improving the bearing capacity of the entire concrete slab.

[0044] like Figure 1 As shown, in this embodiment, a slot 112 is provided on one side of the upper concrete slab 1, and a slide plate 114 is slidably connected in the slot 112. Two sliders 115 are fixedly connected to the lower surface of the slider 114. Positions of the upper concrete slab 1 corresponding to the two sliders 115 are provided with slide grooves 113, and the slide plate 114 can slide along the slide grooves 113 through the sliders 115. A slot 16 is provided on one side of the lower concrete slab 11, and an insert block 17 is inserted in the slot 16. The insert block 17 is made of waterproof material.

[0045] Specifically, a slot 112 is opened on one side of the upper concrete slab 1, and then a slide plate 114 is slidably set in the slot 112. The slide plate 114 can be replaced according to the customized concrete slab. For example, if a concrete slab with good sound insulation needs to be replaced, the slide plate 114 can be replaced with a slide plate with good sound insulation material. When a concrete slab with better heat insulation needs to be replaced, the slide plate 114 can be replaced with a slide plate 114 with good heat insulation material before pouring. Then, a slot 16 is opened in the lower concrete slab 11, and an insert block 17 is inserted in the slot 16. The insert block 17 is made of waterproof material, so that the concrete slab can have a better waterproof effect.

[0046] The working principle of the present application is as follows: first, when the concrete slab is made, a positioning frame 14 is fixedly connected in each positioning groove 15 of the lower concrete slab 11, and the positioning frame 14 is made of silicone foam material, which can achieve high and low temperature resistance, high flame retardancy and other characteristics, and then the upper concrete slab 1 and the lower concrete slab 11 are spliced ​​together, and then concrete is poured into the making frame, and then the concrete will enter the positioning frame 14, and two steel bars 116 in opposite directions are fixedly connected in each positioning frame 14, so that the positioning frame 14 can be supported to a certain extent by the steel bars 116, and when the concrete is poured into the positioning frame 14, the steel bars 116 can improve the compressive strength of the concrete slab, and each steel bar 116 is triangular, so that it is fixed between the upper concrete slab 1 and the lower concrete slab 11, because the silicone foam positioning frame 14 has a lighter material, it can reduce the mass of the concrete slab to a certain extent, thereby achieving the effect of facilitating transportation, and can also have a better heat insulation effect;

[0047] Furthermore, by fixing a positioning block 18 between each two positioning frames 14, and then opening a fixing hole 19 on the side of the positioning block 18, after the concrete is poured into the positioning frame 14, the entire upper concrete slab 1 and the lower concrete slab 11 can form a loop, thereby making the pouring of concrete better and improving the bearing capacity of the entire concrete slab.

[0048] Then, when a larger concrete slab needs to be made, by inserting a plurality of first protrusions 13 on the lower surface of one of the lower concrete slabs 11 into a plurality of first grooves 12 on the upper surface of another upper concrete slab 1, a larger concrete slab frame can be obtained, and at the same time, the strength of the synthesized concrete slab can be ensured, achieving a better use effect, being more practical, adapting to more attempts to produce concrete slabs, and expanding the size types of concrete slabs;

[0049] In addition, a slot 112 is provided on one side of the upper concrete slab 1, and a slide plate 114 is slidably provided in the slot 112. The slide plate 114 can be replaced according to the customized concrete slab. For example, if a concrete slab with good sound insulation needs to be replaced, the slide plate 114 can be replaced with a slide plate 114 with good sound insulation material. If a concrete slab with better heat insulation needs to be replaced, the slide plate 114 can be replaced with a slide plate 114 with good heat insulation material before pouring. Then, a slot 16 is provided inside the lower concrete slab 11, and an insert block 17 is inserted in the slot 16. The insert block 17 is made of waterproof material, so that the concrete slab has a better waterproof effect.
