Concrete connecting structure and concrete building

Abstract

This utility model discloses a concrete connection structure and a concrete building. The concrete connection structure includes a connecting component and a composite reinforcing plate. The connecting component includes connecting steel bars, with each end of the connecting steel bars used to connect to two concrete blocks. The composite reinforcing plate includes a reinforcing base plate and expansion tubes. The reinforcing base plate is disposed between the two concrete blocks, and the connecting steel bars pass through the reinforcing base plate. Multiple expansion tubes are spaced apart within the reinforcing base plate. Each expansion tube includes a fracturing shell and a water-absorbing core disposed within the fracturing shell. The water-absorbing core absorbs liquid and expands. When liquid seeps into the reinforcing base plate, the water-absorbing core absorbs the liquid and expands, increasing the density of the reinforcing base plate.

Description

Technical Field

[0001] This utility model belongs to the field of concrete reinforcement technology, specifically relating to a concrete connection structure and a concrete building. Background Technology

[0002] Rockfill concrete refers to a large-volume concrete block formed by piling up large-diameter boulders to form a rockfill skeleton, and then pouring self-compacting concrete on the rockfill to bind it together. Rockfill concrete has the advantages of simple construction process and good volume stability. However, the surface of rockfill concrete is complex and contains both concrete and boulders, which leads to low connection strength and weak connection when reinforcing and connecting two concrete blocks. This results in poor concrete reinforcement stability. Furthermore, the osmotic pressure and shear stress generated when liquid seeps into the connection between the two concrete blocks can easily lead to connection failure, affecting the overall structural strength of the concrete structure. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies, this utility model provides a concrete connection structure and a concrete building, which aims to solve the technical problems of low connection strength and easy failure of the connection between two concrete blocks.

[0004] To achieve the above objectives, this utility model provides a concrete connection structure, which includes:

[0005] The connecting assembly includes connecting steel bars, the two ends of which are respectively used to connect to two concrete blocks one by one;

[0006] The composite reinforcing plate includes a reinforcing base plate and expansion tubes. The reinforcing base plate is located between two concrete blocks, and the connecting steel bars pass through the reinforcing base plate. Multiple expansion tubes are arranged at intervals inside the reinforcing base plate. Each expansion tube includes a fracturing shell and a water-absorbing core located inside the fracturing shell. The water-absorbing core is used to absorb liquid and expand.

[0007] In this embodiment of the invention, the absorbent core includes an expansion layer and an absorbent block. The expansion layer covers the outside of the absorbent block and is used for liquid permeation, while the absorbent block is used for absorbing liquid.

[0008] In this embodiment of the utility model, the water-absorbing block is made of water-absorbing resin material.

[0009] In this embodiment of the utility model, the reinforcing substrate includes a first connecting plate layer, a reinforcing support plate layer and a second connecting plate layer stacked together. The first connecting plate layer and the second connecting plate layer are respectively connected to two concrete blocks one-to-one, and multiple expansion tubes are arranged at intervals in both the first connecting plate layer and the second connecting plate layer.

[0010] In this embodiment of the utility model, the two concrete blocks are respectively designated as old concrete blocks and new concrete blocks. The first connecting plate layer is connected to the old concrete block, and the second connecting plate layer has a roughened surface on the side facing away from the reinforcing support plate layer. The roughened surface is provided with roughened texture, and the roughened surface is connected to the new concrete block.

[0011] In this embodiment of the utility model, the connecting steel bar includes a rebar section, a pre-embedded section, and a connecting section. One end of the pre-embedded section is connected to the rebar section, and the other end of the pre-embedded section is connected to the connecting section. The pre-embedded section passes through the first connecting plate layer, the reinforcing support plate layer, and the second connecting plate layer. A rebar hole is opened on the old concrete block, and the rebar section extends into the rebar hole and connects with the old concrete block. The connecting section is connected with the new concrete block.

[0012] In this embodiment of the utility model, the length of the rebar segment is not less than 100mm, the length of the connecting segment is not less than 100mm, and the diameter of the connecting rebar is not less than 16mm.

[0013] In this embodiment of the invention, the connecting component includes multiple connecting steel bar groups, which are spaced apart along a first direction, and each connecting steel bar group includes multiple connecting steel bars spaced apart along a second direction.

[0014] To achieve the above objectives, this utility model also provides a concrete building, which includes the concrete connection structure described above.

[0015] Through the above technical solutions, the concrete connection structure and concrete building provided by the embodiments of this utility model have the following beneficial effects:

[0016] In the technical solution of this utility model, a reinforcing base plate is disposed between two concrete blocks and connected to each of the two concrete blocks respectively. Connecting steel bars are inserted through the reinforcing base plate and extend into the two concrete blocks respectively to connect the two concrete blocks. Furthermore, multiple expansion tubes are provided inside the reinforcing base plate. Each expansion tube includes a fracturing shell and a water-absorbing core. The fracturing shell covers the water-absorbing core. When the reinforcing base plate is connected to the concrete blocks, it is subjected to pressure from the concrete blocks. The pressure from the concrete blocks acts on the fracturing shell through the reinforcing base plate, causing the fracturing shell to rupture and exposing the water-absorbing core. When liquid seeps into the reinforcing base plate, the water-absorbing core can absorb the liquid and expand to increase the density of the reinforcing base plate. This allows the two sides of the reinforcing base plate to be in close contact with the two concrete blocks respectively, improving the impermeability and shear resistance at the connection between the two concrete blocks, thereby strengthening the connection strength between the two concrete blocks. This effectively prevents connection failure caused by liquid seepage between the two concrete blocks and improves the overall structural strength of the concrete building.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] The concrete connection structure of this utility model is described below with reference to the accompanying drawings.

[0027] like Figures 1 to 4As shown, this utility model provides a concrete connection structure, which includes a connection component and a composite reinforcing plate 20. The connection component includes a connecting steel bar 10, and the two ends of the connecting steel bar 10 are respectively used to connect to two concrete blocks 200 one by one. The composite reinforcing plate 20 includes a reinforcing base plate 21 and expansion tubes 22. The reinforcing base plate 21 is disposed between the two concrete blocks 200, and the connecting steel bar 10 passes through the reinforcing base plate 21. Multiple expansion tubes 22 are arranged at intervals in the reinforcing base plate 21. Each expansion tube 22 includes a fracturing shell 221 and a water-absorbing core 222 disposed in the fracturing shell 221. The water-absorbing core 222 is used to absorb liquid and expand.

[0028] It should be noted that the concrete block 200 is a block structure formed by concrete pouring. The concrete block 200 can be a block structure containing only concrete, or it can be a riprap concrete block structure containing concrete and riprap. This utility model does not limit the structural form of the concrete block 200, and the concrete block 200 is applied to concrete buildings.

[0029] Specifically, the reinforcing base plate 21 is disposed between and connected to the two concrete blocks 200 respectively. Connecting steel bars 10 pass through the reinforcing base plate 21 and extend into the two concrete blocks 200 respectively to connect them. Furthermore, the reinforcing base plate 21 is provided with multiple expansion tubes 22, each including a fracturing shell 221 and a water-absorbing core 222. The fracturing shell 221 covers the water-absorbing core 222. When the reinforcing base plate 21 is connected to the concrete blocks 200, it is subjected to pressure from the concrete blocks 200. This pressure is transmitted through the reinforcing base plate 21. The water-absorbing core 222 is used on the fracturing shell 221 to cause the fracturing shell 221 to rupture and expose the water-absorbing core 222. When liquid seeps into the reinforcing base plate 21, the water-absorbing core 222 can absorb the liquid and expand to increase the density of the reinforcing base plate 21. This allows the two sides of the reinforcing base plate 21 to be in close contact with the two concrete blocks 200, improving the impermeability and shear resistance at the connection between the two concrete blocks 200. This strengthens the connection strength between the two concrete blocks 200, effectively preventing connection failure caused by liquid seepage between the two concrete blocks 200, and improving the overall structural strength of the concrete building.

[0030] In this embodiment of the invention, the absorbent core 222 includes an expansion layer 2221 and an absorbent block 2222. The expansion layer 2221 covers the outside of the absorbent block 2222. The expansion layer 2221 is used for liquid permeation, and the absorbent block 2222 is used for absorbing liquid. Figures 1 to 4As shown, the fracturing shell 221 covers the outside of the expansion layer 2221, and the expansion layer 2221 covers the outside of the water-absorbing block 2222. The fracturing shell 221 can stably cover the expansion layer 2221 and the water-absorbing block 2222 when the reinforcing substrate 21 is not under pressure, preventing the water-absorbing block 2222 from absorbing water and expanding when it comes into contact with liquid, thus improving structural stability. Furthermore, when the fracturing shell 221 is subjected to pressure and fractures when the concrete block 200 is connected to the reinforcing substrate 21, the expansion layer 2221 is exposed. When the liquid penetrates through the expansion layer 2221, the water-absorbing block 2222 absorbs the liquid and pushes the expansion layer 2221, causing the expansion layer 2221 to expand and densely fill the reinforcing substrate 21. The increased density of the reinforcing substrate 21 presses against the concrete block 200, strengthening the connection strength and improving shear resistance and impermeability.

[0031] Furthermore, the water-absorbing block 2222 is made of water-absorbing resin. The water-absorbing resin block 2222 can absorb 250g / g of water in distilled water and 50g / g of water in simulated concrete pore solution. This allows the water-absorbing block 2222 to absorb liquid and expand when in contact with liquid. The expansion layer 2221 is made of cement mortar. When the water-absorbing block 2222 expands, it pushes the expansion layer 2221, causing the expansion layer 2221 to deform and fill the pores of the reinforcing substrate 21, thereby improving the density of the reinforcing substrate 21 and thus improving the shear resistance and impermeability between the two concrete blocks 200. In addition, microcrystalline cellulose can be added to the expansion layer 2221 as a disintegrant, so that the expansion layer 2221 can quickly disintegrate and densely fill the reinforcing substrate 21 when pushed by the water-absorbing block 2222, further improving the structural strength of the reinforcing substrate 21.

[0032] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the reinforcing substrate 21 includes a first connecting plate layer 211, a reinforcing support plate layer 212, and a second connecting plate layer 213 stacked together. The first connecting plate layer 211 and the second connecting plate layer 213 are respectively connected to two concrete blocks 200 in a one-to-one correspondence, and both the first connecting plate layer 211 and the second connecting plate layer 213 are provided with a plurality of expansion tubes 22 arranged at intervals. The reinforcing support plate is disposed between the first connecting plate layer 211 and the second connecting plate layer 213 and is used to support the first connecting plate layer 211 and the second connecting plate layer 213, further improving the structural strength of the reinforcing substrate 21.

[0033] Furthermore, the two concrete blocks 200 are respectively designated as old concrete block 200a and new concrete block 200b. The first connecting plate layer 211 is connected to the old concrete block 200a. The second connecting plate layer 213 has a roughened surface 2131 on the side facing away from the reinforcing support plate layer 212. The roughened surface 2131 has roughened texture and is connected to the new concrete block 200b.

[0034] like Figures 1 to 4 As shown, when reinforcing the old concrete block 200a, a new concrete block 200b needs to be connected to the old concrete block 200a to enhance structural strength and stability. First, the connecting steel bar 10 is inserted into the old concrete block 200a and connected to it. Then, the first connecting plate layer 211 is connected to the old concrete block 200a. Next, concrete is poured on the side where the roughened surface 2131 is located to form the new concrete block 200b. Then, concrete is poured on the new concrete block 200b. Previously, the fracturing shell 221 was wrapped around the expansion layer 2221 and the water-absorbing block 2222, ensuring that the reinforcing base plate 21 would not affect the pouring of the new concrete block 200b, thus guaranteeing the pouring effect of the new concrete block 200b. Furthermore, during the pouring process of the new concrete block 200b, it hardened and exerted pressure on the first connecting plate layer 211 and the second connecting plate layer 213, which in turn acted on the fracturing shell 221. The fracturing shell 221 ruptures, exposing the expansion layer 2221. As liquid seeps into the expansion layer 2221, the absorbent block 2222 absorbs the liquid and expands, pushing against the expansion layer 2221. This causes the expansion layer 2221 to densely fill the pores of the first connecting plate layer 211 and the second connecting plate layer 213. The first connecting plate layer 211 presses firmly against the old concrete block 200a, and the roughened surface 2131 of the second connecting plate layer 213 presses firmly against the new concrete block 200b, significantly improving the performance of the old concrete block 200a. The shear resistance and impermeability of the concrete block 200a and the new concrete block 200b are improved. Furthermore, the hardness of the reinforcing support plate is greater than that of the first connecting plate layer 211 and the second connecting plate layer 213. This not only facilitates close contact between the first connecting plate layer 211 and the second connecting plate layer 213 and the old concrete block 200a and the new concrete block 200b respectively under expansion, but also ensures stable support of the first connecting plate layer 211 and the second connecting plate layer 213, thus improving structural stability. Moreover, the roughened surface 2131 of the second connecting plate layer 213 is treated with a roughening process in the prior art to form roughened textures. The new concrete block 200b is poured onto the roughened surface 2131, further strengthening the connection strength between the second connecting plate layer 213 and the new concrete block 200b.

[0035] In this embodiment of the utility model, the connecting steel bar 10 includes a rebar section 11, a pre-embedded section 12, and a connecting section 13. One end of the pre-embedded section 12 is connected to the rebar section 11, and the other end of the pre-embedded section 12 is connected to the connecting section 13. The pre-embedded section 12 is disposed through the first connecting plate layer 211, the reinforcing support plate layer 212, and the second connecting plate layer 213. A rebar hole is opened on the old concrete block 200a. The rebar section 11 extends into the rebar hole and is connected to the old concrete block 200a. The connecting section 13 is connected to the new concrete block 200b.

[0036] like Figures 1 to 4 As shown, the old concrete block 200a has anchoring holes. The anchoring segment 11 of the connecting steel bar 10 extends into the anchoring hole and is connected to the anchoring hole, which strengthens the connection strength between the first connecting plate layer 211 and the old concrete block 200a, making the connection stable and reliable. The pre-embedded segment 12 passes through the first connecting plate layer 211, the reinforcing support plate layer 212 and the second connecting plate layer 213 to connect the first connecting plate layer 211, the reinforcing support plate layer 212 and the second connecting plate layer 213, making the connection stable and reliable. Furthermore, the connecting segment 13 extends out of the roughened surface 2131. The new concrete block 200b is cast and formed on the side where the roughened surface 2131 is located, so that the connecting segment 13 extends into and is connected to the new concrete block 200b, which greatly improves the shear resistance and the reinforcement stability of the concrete block 200.

[0037] Furthermore, the rebar segment 11 extends into the rebar hole and connects with the old concrete block 200a. The length of the rebar segment 11 is not less than 100mm to strengthen the connection strength between the rebar segment 11 and the old concrete block 200a. Similarly, the connecting segment 13 extends into the new concrete block 200b and connects with it. The length of the connecting segment 13 is not less than 100mm to strengthen the connection strength between the connecting segment 13 and the new concrete block 200b. The diameter of the connecting steel bar 10 is not less than 16mm to enhance the shear resistance of the old concrete block 200a, the reinforcing base plate 21, and the new concrete block 200b. The connection is stable and reliable, improving the stability of the reinforcement. In addition, the connecting steel bar 10 can be HRB400 ribbed steel bar from the prior art, further improving the tensile strength of the connecting steel bar 10 and extending its service durability.

[0038] In this embodiment of the invention, the connecting assembly includes multiple groups of connecting steel bars, which are spaced apart along a first direction. Each group of connecting steel bars includes multiple connecting steel bars 10 spaced apart along a second direction. Figures 1 to 4As shown, the first direction is set as the front-back direction and the second direction is set as the left-right direction. Multiple connecting steel bar groups are spaced apart along the front-back direction. Multiple connecting steel bars 10 in each connecting steel bar group are spaced apart along the left-right direction. Each connecting steel bar 10 passes through the reinforcing base plate 21 and is connected to the old concrete block 200a and the new concrete block 200b respectively, which greatly improves the connection strength and reinforcement stability between the new concrete block 200b and the old concrete block 200a.

[0039] Furthermore, this utility model also provides a concrete structure, which includes the concrete connection structure described above. The concrete structure also includes an old concrete block 200a and a new concrete block 200b. The two ends of the connecting steel bar 10 are respectively connected to the old concrete block 200a and the new concrete block 200b. The first connecting plate layer 211 is connected to the old concrete block 200a, and the roughened surface 2131 of the second connecting plate layer 213 is connected to the new concrete block 200b, thereby improving the connection stability between the old concrete block 200a and the new concrete block 200b.
