The wall formed by traditional masonry or simple grouting is mainly two-dimensional plane bonding between blocks, and the integrity is limited, and the seismic pull of the main structure often depends on the post-positioned metal parts, and the synergy with the wall itself reinforcing system is insufficient.

DETAILED DESCRIPTION

[0041] Please refer to Figures 1-6 In an embodiment of the present application, an environment-friendly assembled autoclaved aerated concrete block structure comprises:

[0042] The block body 1 is made of autoclaved aerated concrete, and a grouting channel system is arranged inside the block body 1.

[0043] The corner protection and clamping system comprises a plurality of corner protection units 2, each of which is composed of three mutually perpendicular plate members and is arranged at each corner of the block body 1 to cover three adjacent surfaces of the corner.

[0044] The plurality of block bodies 1 are fixed and clamped by the corner protection and clamping system, and a structural gap 3 for filling grout is formed between the facing surfaces of two adjacent block bodies 1, and the structural gap 3 is connected to the grouting channel system.

[0045] Specifically, the corner protection unit 2 can effectively protect the corners of the block body 1 during transportation to prevent damage to the block body 1 caused by bumps during transportation.

[0046] In this embodiment, the three plate members in the corner protection unit 2 are respectively:

[0047] The first protection plate 21 is embedded on the surface of the block body 1 in the height direction;

[0048] The second protection plate 22 is embedded on the surface of the block body 1 in the width direction;

[0049] The third protection plate 23 is embedded on the surface of the block body 1 in the length direction;

[0050] And the auxiliary plate 24 is connected between the two third protection plates 23 adjacent to each other on the same side of the same block body 1.

[0051] In particular, the width of the auxiliary plate 24 is the same as that of the third protection plate 23, which functions to cover the vertical joint between the two third protection plates 23, and ensures that the side walls of the structural gap 3 between the adjacent block bodies 1 in the horizontal direction are formed by the third protection plate 23 and the auxiliary plate 24 to form a continuous and uninterrupted sealing interface.

[0052] In addition, the first protection plate 21, the second protection plate 22, the third protection plate 23 and the auxiliary plate 24 are all of a composite structure, the outer layer of which is a high-rigidity protection layer made of thick glass fiber reinforced nylon, and the inner layer of which is a buffer layer made of modified elastomer, which has the ability to resist impact and absorb slight deformation.

[0053] In the embodiment, the first protection plate 21 is a trapezoidal plate with an inclined surface, the inclined surface of two of the four first protection plates 21 on the bottom of the block body 1 in the width direction is fixedly provided with a first clamping strip 211, and the inclined surface of the other two of the four first protection plates 21 is fixedly provided with a second clamping strip 212 in the shape of T in cross section, and the height of the first clamping strip 211 and the second clamping strip 212 is not more than the maximum height of the first protection plate 21.

[0054] That is, no matter how the block body 1 is placed, the corner protection unit 2 will always be in contact with the external environment first, preventing the block body 1 from being damaged by force, and the inclined surface is provided on the first protection plate 21, so that the inclined surface itself will not protrude from the first protection plate 21, and then the first clamping strip 211 and the second clamping strip 212 are provided on the inclined surface, and the height of the two is set to be not more than the height of the first protection plate 21, which makes the first protection plate 21 also contact the external environment first, so that the first clamping strip 211 and the second clamping strip 212 are further protected from being damaged.

[0055] The inclined surface of two of the four first protection plates 21 on the top of the block body 1 in the width direction is provided with a first clamping groove 213 matched with the first clamping strip 211, and the inclined surface of the other two of the four first protection plates 21 is provided with a second clamping groove 214 matched with the second clamping strip 212, and the vertical positions of the two first clamping grooves 213 correspond to the vertical positions of the two second clamping strips 212, and the vertical positions of the two second clamping grooves 214 correspond to the vertical positions of the two first clamping strips 211.

[0056] In the embodiment, the four third protection plates 23 on the same side of the block body 1 are fixedly provided with clamping blocks 231, and the four third protection plates 23 on the other side are provided with third clamping grooves 232, and the clamping block 231 on the block body 1 can be clamped into the third clamping groove 232 on another block body 1 adjacent to the block body 1.

[0057] In the vertical splicing of the block body 1, the T-shaped second clamping strip 212 on the upper block body 1 is aligned with the second clamping groove 214 on the lower block body 1, and the second clamping strip 212 is pushed into the second clamping groove 214, so that the two block bodies 1 are spliced together. During the sliding clamping of the second clamping strip 212 and the second clamping groove 214, the first clamping strip 211 on the other two first protection plates 21 at the bottom of the upper block body 1 is aligned with and clamped into the first clamping groove 213 at the top of the adjacent block body 1 of the lower block body 1. Since the block body 1 is laid in a staggered manner, the splicing between the three block bodies 1 is completed, and after splicing, the adjacent two block bodies 1 in the horizontal direction are clamped by the clamping block 231 and the clamping groove 232, thereby completing the positioning and clamping between the block bodies 1.

[0058] In the embodiment, the second clamping groove 214 is a double-step structure, which includes a guide step with a larger cross section arranged at the initial section of the inclined surface to allow the second clamping strip 212 to smoothly slide in, and a locking step with a cross section precisely matched with the head of the second clamping strip 212 to clamp the second clamping strip 212 arranged at the end section of the inclined surface. That is, when the second clamping strip 212 is completely clamped into the second clamping groove 214, a pre-connection point is formed between the two block bodies 1.

[0059] In the embodiment, the first clamping strip 211 and the first clamping groove 213 are designed as an interference fit, that is, the first clamping strip 211 also has locking force after being clamped into the first clamping groove 213, further improving the connection strength of the pre-spliced block body 1.

[0060] In the embodiment, when a plurality of block bodies 1 are laid in a staggered manner along the height direction, the first protection plates 21 in the corresponding corner protection units 2 of at least three block bodies 1 on the same vertical line can form a complete plate along the inclined surface, and the length of the complete plate is equal to the length of the block body 1.

[0061] Specifically, the length of the first protective plate 21 along the length of the block body 1 is one-third of the length of the block body 1, while the span of the inclined plane along the length of the first protective plate 21 is equal to half the length of the first protective plate 21. This allows the two first protective plates 21 at corresponding positions between two block bodies 1 to precisely interlock through the inclined plane when the block bodies 1 are laid in a staggered manner, forming a complete plate structure. Due to the staggered laying, the upper block body 1 will fit against the two bottom block bodies 1, meaning that the four first protective plates 21 at corresponding positions of the three block bodies 1 will interlock to form a strip of the same length as the block body 1. The complete sheet metal can form a continuous sealing interface, providing a side seal for the structural gap 3 formed between the three main blocks. At the same time, the third protective plate 23 at the corresponding position between two adjacent main blocks 1 in the horizontal direction will be engaged, and the auxiliary plate 24 will further form a sealing interface, providing a side seal for the structural gap 3 formed between two adjacent main blocks 1 in the horizontal direction. This eliminates the need to set an additional sealing interface during grouting, and allows the sealing interface to be automatically formed after splicing, eliminating the process and uncertainty of manual sealing, and achieving the efficient goal of "dry assembly to complete the preparation of the joint cavity".

[0062] In this embodiment, the grouting channel system includes a vertical channel 11 opened along the height direction of the block body 1 and a horizontal channel 12 opened along the length direction of the block body 1 and intersecting and communicating with the vertical channel 11. A node distribution mechanism is provided at the intersection of the vertical channel 11 and the horizontal channel 12.

[0063] In this embodiment, the node allocation mechanism includes a spherical chamber 13 opened in the block body 1 and a spherical diversion cone 14 disposed in the spherical chamber 13. The spherical diversion cone 14 is fixedly connected to the inner wall of the spherical chamber 13 by at least two helical support wing plates 15.

[0064] Specifically, after the construction of each layer of the block body 1 is completed, grout is filled into the grouting channel system through the vertical channel 11 above the block body 1. When the grout enters the spherical chamber 13 along the vertical channel 11, it will hit the spherical flow divider 14. Then the grout will be divided into three streams: one stream is reflected by the cone along the inner wall of the spherical chamber 13 downward, fills the chamber and continues to descend; the other two streams are guided by the spiral support wing plate 15 to generate rotational momentum, so that they can more smoothly and uniformly enter the horizontal channels 12 on both sides, effectively avoiding the accumulation of aggregates and air bags at the inlet of the horizontal channel 12 caused by the straight impact of the grout. Moreover, the grout entering the grouting channel system will be guided to the structural gap 3, that is, the grout will be transported to the structural gap 3 between the block bodies 1 in the vertical direction by the vertical channel 11, and the grout will be transported to the structural gap 3 between the block bodies 1 in the horizontal direction by the horizontal channel 12. When the grout fills the structural gap 3 and the grouting channel system, it can form a complete grout framework, which greatly improves the shear strength of the wall.

[0065] A construction method for building a wall body of a concrete block structure, comprising the following steps:

[0066] S1, a plurality of block bodies 1 are spliced by the corner protection and clamping system to complete the construction of the first construction layer;

[0067] Specifically, a plurality of block bodies 1 are arranged horizontally, and then pushed to slide so that the clamping blocks 231 at the corresponding positions on the adjacent two block bodies 1 are clamped into the third clamping grooves 232 to complete the construction of the block bodies 1 in the horizontal direction;

[0068] It should be noted that the clamping block 231 and the third clamping groove 232 also adopt interference fit or transition fit, that is, the clamping block 231 can slide into the third clamping groove 232 and be clamped and fixed after being in place;

[0069] S2, grout is injected from the top of the first construction layer, and the grout fills the structural gap 3 of the layer through the grouting channel system;

[0070] It should be noted that since there is only a single block body 1 in the vertical direction on the first construction layer, there will be a gap between the bottom side and the base layer, and the side of this gap does not have a sealing boundary. Therefore, when performing the first layer grouting work, the boundary of this gap needs to be auxiliary sealed, for example, a fish wall body long foamed polyethylene sealing strip or a temporary sealing paste can be laid on the base layer, and then the grouting work is performed;

[0071] S3, after the grouting of the layer is completed, the next construction layer is constructed on it, and the block bodies 1 between the two construction layers are spliced by using the corner protection and clamping system to complete the construction of the next construction layer, and the grouting work in step S2 is repeated;

[0072] In particular, when the next construction layer is built, since the block body 1 is staggered, the structural gap 3 between the upper block body 1 and the lower block body 1 is sealed by the first protective plate 21 on both sides, and the structural gap 3 between the horizontally adjacent two block bodies 1 is sealed by the third protective plate 23 and the auxiliary plate 24, that is, after splicing, a sealed boundary is automatically formed, and thus, in addition to the first construction layer grouting requiring auxiliary sealing, subsequent construction layers do not need to be sealed, further accelerating the wall building rate.

[0073] S4, repeat step S3 until the wall is completed, and the grout solidifies to form a three-dimensional reinforced skeleton.

[0074] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
