Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and specifically to a reinforced ALC board and a structure in which the reinforced ALC board is used as a floor slab and a wall board. Background Art

[0002] Autoclaved aerated concrete is internally provided with steel mesh sheets of different specifications and different quantities that have been subjected to rust prevention treatment, and autoclaved aerated concrete boards (ALC boards) for different uses can be manufactured, such as being used as roof panels, exterior wall panels, partition walls, and floor slabs.

[0003] The ALC board has the advantages of being lightweight, heat-insulating, fire-resistant, etc., but it also has disadvantages. On the one hand, since the ALC board is foamed concrete, its compressive strength is not high and its tensile strength is very low; when the ALC board is used as an exterior wall panel, it will be affected by the external environment, such as freeze-thaw, carbonation, alternate action of dry-wet cycles, temperature changes, etc., and the ALC board itself is prone to cracking; in addition, the joints between ALC boards are also prone to cracking due to the influence of alternate dry-wet cycles, temperature changes, wind vibration effects, etc. On the other hand, the ALC board has a large number of air bubbles and holes, and there are air bubbles at the contact surface between the autoclaved aerated concrete and the steel mesh sheet, the contact surface is not tight and continuous, the autoclaved aerated concrete has a poor grip on the steel mesh sheet, the steel mesh sheet is prone to slipping, and the ability of the steel mesh sheet to work together with the autoclaved aerated concrete is poor. In addition, the connected air bubbles and holes in the autoclaved aerated concrete make the steel mesh sheet contact with the moisture in the air, resulting in the steel mesh sheet being prone to rust, so the specification requires that the steel mesh sheet inside the ALC board needs to be subjected to rust prevention treatment; moreover, the ALC board belongs to a porous structure, and when attaching devices such as doors, windows, air conditioners, water heaters, water tanks, etc. are installed on the wall, the fixed bolts are prone to loosening.

[0004] Currently, when the ALC board is used for walls, the specification only allows the ALC board to be used as a self-bearing wall. For example, the "Technical Specification for the Application of Autoclaved Aerated Concrete Wallboard System" (DB11 / T 2003-2022) of the local industry standard in Beijing and the "Technical Specification for the Application of Autoclaved Aerated Concrete Wallboard" (DB33 / T 1232-2021) in Zhejiang both state that the ALC board is only used for non-bearing partition walls. In addition, due to the insufficient strength and low bearing capacity of the ALC board itself, there are many limitations in the application of the ALC board in floor slabs.

[0005] By strengthening the ALC board itself in a certain way, the applicable range of the ALC board can be expanded. For example, holes parallel to the board surface are drilled inside the ALC board, and steel bars are placed in the holes and grouted, thereby improving the strength of the ALC board. However, this strengthening method has the following deficiencies: First, it is difficult to process holes inside the ALC board, and it is not easy to ensure flatness. Especially when the holes are very long, they are prone to tilt, making it difficult to control the hole forming quality; Second, when grouting, it is impossible to observe the slurry situation, making it difficult to ensure that the slurry completely fills the holes, and it is difficult to ensure the grouting quality. There is also a problem that there may be no concrete outside the steel bars or the concrete cover thickness is insufficient, resulting in the steel bars being easily corroded.

[0006] When the ALC board is used as the wall board of a self-bearing wall, there is also the problem of how to splice the wall boards. The existing splicing methods are mainly that one side has a groove and the other side has a protrusion, which are mutually adapted for splicing, and an adhesive is filled at the splicing part; when a construction column needs to be set, grooves are respectively set on the two splicing surfaces, steel bars are arranged in the grooves and concrete is cast in situ to form an inner-encased construction column. For example, Article 5.5.9 of the existing specification "Technical Standard for Application of Autoclaved Aerated Concrete Products" (JGJ / T 17 - 2020, Record Number J 824 - 2020) stipulates that "Inner-encased construction columns should be preferably used for self-bearing walls, and the column width should not be less than 100 mm" and "When there is an opening with a width greater than 2.1 m in the infill wall, three-sided double-reinforced concrete columns with a width not less than 50 mm should be added on both sides of the opening". For the ALC board splicing method given in the above specification, the connection between ALC boards is very weak, and the crack resistance of the splicing joint is poor. Summary of the Invention

[0007] The present invention first provides a strengthened ALC board, and the primary purpose is to improve the bearing capacity of the ALC board for loads perpendicular to the board surface of the ALC board.

[0008] The technical solution adopted by the present invention is: The strengthened ALC board includes a board body. The board body has two mutually parallel board surfaces, as well as two end faces and two side faces. At least one strengthening band is respectively arranged on each board surface. The strengthening band at least includes a transverse strengthening band and / or a longitudinal strengthening band. The two ends of the transverse strengthening band extend to the two side faces, and the two ends of the longitudinal strengthening band extend to the two end faces. The strengthening bands are arranged straight; The strengthening band is a prefabricated reinforcing body, or a cast-in-situ reinforcing body, or a reinforcing body that is partially prefabricated and partially cast-in-situ, and the reinforcing body is either reinforced or not.

[0009] The beneficial effect of the above strengthened ALC board is: When a load perpendicular to the board surface of the strengthened ALC board acts on the board body, one board surface of the board body is in tension and the other board surface is in compression. The present invention correspondingly arranges strengthening bands on the two board surfaces of the board body respectively, and the strengthening bands strengthen the two board surfaces respectively, improving the ability of the two board surfaces of the board body to be in tension and compression, thereby improving the ability of the strengthened ALC board to bear loads perpendicular to its board surface.

[0010] In order to uniformly strengthen a plate body with a cuboid-shaped outer contour, further: the plate surface, end surface, and side surface of the plate body are perpendicular to each other in any two cases; the transverse strengthening bands are parallel to each other and parallel to the end surface, and the longitudinal strengthening bands are parallel to each other and parallel to the side surface. The transverse strengthening bands and longitudinal strengthening bands located on the same plate surface intersect and are connected at the foot of the perpendicular.

[0011] In order to equally strengthen the two plate surfaces of the plate body and avoid the need to distinguish between the two plate surfaces of the plate body, further: the projections of the strengthening bands on the two plate surfaces of the plate body on a plane parallel to the plate surface coincide.

[0012] In order to facilitate the production and manufacture of the strengthening bands on the plate body, further: grooves are provided on the surface of the plate body, the strengthening bands are located at the grooves, and the surface of the strengthening bands is flush with, protrudes from, or is lower than the corresponding surface of the plate body.

[0013] The grooves on the surface of the plate body can be of any shape in its cross-section. In order to facilitate the production and manufacture of the strengthening bands, optimize the force-bearing of the strengthening bands, and ensure the strengthening effect of the strengthening bands, specifically: the grooves on the surface of the plate body are in a shape with the same size of the groove opening and the groove bottom or a shape with the groove opening larger than the groove bottom in its cross-section. For example, the grooves are rectangular, semi-circular, or trapezoidal in its cross-section.

[0014] In order to realize the connection of the plate body with other structures through the reinforcement bars of the strengthening bands, further: the two ends of the reinforcement bars of at least one strengthening band are respectively extended beyond the corresponding end surface or side surface.

[0015] For the strengthening bands, the reinforcing body alone plays a role in strengthening the plate body, or the reinforcing body and the reinforcement bars are combined with each other to jointly bear the force, and the reinforcing body and the reinforcement bars jointly play a role in strengthening the plate body. Specifically: the reinforcing body is mortar, fine aggregate concrete, ceramsite concrete, cement-based grouting material, high-strength gypsum, epoxy resin grouting material, etc.

[0016] In order to facilitate the splicing of the strengthened ALC plate with another strengthened ALC plate into a larger-area plate member by using the side surface or end surface in a cast-in-place manner, or to facilitate the strengthening of the side surface or end surface by cast-in-place, further: at least one of the four surfaces, namely the two side surfaces and the two end surfaces of the plate body, is provided with a splicing groove, the splicing groove is a cast-in-place groove, and the center line of the splicing groove is parallel to the plate surface.

[0017] In order to reduce the risk of separation between the reinforcement band and the plate body after the reinforced ALC plate is stressed, ensure the reinforcement effect of the reinforcement band on the plate body, and improve the shear resistance of the reinforced ALC plate, further: "There is at least one group of transverse reinforcement bands located on different plate surfaces and corresponding to each other, each group consists of two transverse reinforcement bands, and at least one group of transverse reinforcement bands are connected in a ring on the side surface of the plate body to form a transverse ring-shaped reinforcement band" and / or "There is at least one group of longitudinal reinforcement bands located on different plate surfaces and corresponding to each other, each group consists of two longitudinal reinforcement bands, and at least one group of longitudinal reinforcement bands are connected in a ring on the end surface of the plate body to form a longitudinal ring-shaped reinforcement band".

[0018] The plate body of the reinforced ALC plate is generally a strip board. Therefore, the area of the plate surface is greater than or much greater than the area of the side surface, and the area of the side surface is greater than or much greater than the area of the end surface. The following provides a typical reinforcement method for a reinforced ALC plate with a strip board as the plate body: Longitudinal reinforcement bands are respectively arranged on the two plate surfaces of the plate body, each longitudinal reinforcement band is parallel to each other, and the reinforcement of the longitudinal reinforcement band extends beyond the end surface; Transverse reinforcement bands are also respectively arranged on the two plate surfaces of the plate body, each transverse reinforcement band is parallel to each other and perpendicular to the longitudinal reinforcement band, and the transverse reinforcement band and the longitudinal reinforcement band intersect and are connected at the foot of the perpendicular. Two transverse reinforcement bands located on different plate surfaces and corresponding to each other are connected in a ring on the side surface of the plate body to form a transverse ring-shaped reinforcement band.

[0019] The reinforced ALC plates are generally spliced through the side surfaces. Both side surfaces of the plate body may be used for splicing with the plate body, or only one side surface may be used for splicing with the plate body.

[0020] For a reinforced ALC plate with only one side surface used for splicing with the plate body and the other side surface directly forming an end surface, in order to facilitate the splicing of the plate bodies by in-situ casting and to reinforce the non-spliced side surface, further: The plate body is provided with a transverse ring-shaped reinforcement band, the reinforcement of the transverse ring-shaped reinforcement band is in a ring shape, side grooves are provided on both side surfaces of the plate body, and the center line of the side groove is parallel to the plate surface; There is a side reinforcement band in one side groove, the side reinforcement band is a precast and reinforced reinforcing body, and the side reinforcement band intersects and is connected with the transverse ring-shaped reinforcement band; The other side groove is an in-situ casting groove, and the reinforcement of the transverse ring-shaped reinforcement band in this side groove protrudes from this side surface.

[0021] When the plate body of the reinforced ALC plate is a strip board, in order to improve the ability of the reinforced ALC plate to bear the load perpendicular to the side surface of the plate body, for example, when the side surface of the plate body is placed horizontally and the reinforced ALC plate is used at the top of a door opening or a window opening and also serves as a wall and a beam, one reinforcement method of the reinforced ALC plate is: The plate body is provided with a transverse ring-shaped reinforcement band, the reinforcement of the transverse ring-shaped reinforcement band is in a ring shape; At least one side surface of the plate body is provided with a side reinforcement band, the side reinforcement band intersects and is connected with the transverse ring-shaped reinforcement band, the side reinforcement band is a reinforced reinforcing body, and all of the reinforcing body of the side reinforcement band is precast, or all is cast in-situ, or part is precast and part is cast in-situ.

[0022] For a reinforced ALC board with both side surfaces used for splicing with a plate body, in order to insert steel bars and cast-in-place connect after splicing two plate bodies, and improve the integrity and seismic resistance of the plate bodies after splicing, further: the plate body is provided with a transverse annular reinforcement belt, the reinforcement of the transverse annular reinforcement belt is annular, both side surfaces of the plate body are provided with side grooves, the center line of the side grooves is parallel to the plate surface, both side grooves are cast-in-place grooves and correspond to each other, the reinforcement of the transverse annular reinforcement belt in the two side grooves protrudes from this side surface, and the height of the reinforcement protruding from the side surface is not greater than the depth of the side groove.

[0023] In addition, if the plate bodies of two reinforced ALC boards are spliced with each other through the side surfaces and it is impossible to insert steel bars into the side grooves from the end surface of the plate body due to the obstruction of other objects, in this case, in order to improve the connection strength between the plate bodies, further: the plate body is provided with a transverse annular reinforcement belt, the two side surfaces of the plate body are respectively provided with side grooves, both side grooves are cast-in-place grooves and correspond to each other, at least one blind hole is provided at the bottom of one side groove, and the reinforcement of the transverse annular reinforcement belt on the other side surface is provided with an extension protruding from this side surface, and the extension corresponds to the blind hole.

[0024] In order to enable the reinforcement of the transverse annular reinforcement belt of the reinforced ALC board to extend into the side groove of the adjacent plate body or other cast-in-place structures after splicing with another reinforced ALC board through the side surface, thereby improving the cast-in-place splicing strength of the reinforced ALC board or the integrity with other cast-in-place structures, even further: the reinforcement of the transverse annular reinforcement belt protrudes from the side surface on the side with the blind hole, and the height of the reinforcement protruding from the side surface is not greater than the depth of the side groove.

[0025] The present invention also provides a floor slab structure, the purpose of which is to realize the integration of heat insulation and structure of the floor slab. The floor slab structure includes at least two of the above-mentioned reinforced ALC boards, each plate body is spliced with each other through the side surface to form a floor slab, a splicing joint is formed between the plate bodies, one plate surface of the plate body forms the top surface of the floor slab, the other plate surface forms the bottom surface of the floor slab, and the reinforcement belt of the plate body includes a transverse reinforcement belt and a longitudinal reinforcement belt, and the reinforcement belt is a precast or cast-in-place reinforcing body with reinforcement.

[0026] Further: the transverse reinforcement belts on the two plate surfaces of the plate body are connected into a ring on the side surface of the plate body and form a transverse annular reinforcement belt, and the reinforcement of the transverse annular reinforcement belt is annular.

[0027] In order to make the plate bodies more stable after being spliced with each other through the sides, further: side grooves are provided on both sides of the splicing seam, the center line of the side groove is parallel to the plate surface, the side grooves on both sides of the splicing seam are all cast-in-place grooves and correspond to each other, the reinforcement bars of the transverse annular reinforcement belts of the two plate bodies on both sides of the splicing seam are intertwined in the cavity formed by the splicing of the two side grooves, at least one reinforcing bar is arranged in the intertwined area along the length direction of the side groove, and a reinforced body is cast-in-place in the cavity formed by the splicing of the two side grooves on both sides of the splicing seam to form an embedded hidden beam.

[0028] In order to realize the formwork-free construction of the cast-in-place part of the floor slab structure, further: the reinforcement belt at the bottom of the floor slab is a precast and reinforced reinforced body, the longitudinal reinforcement belt at the top of the floor slab is a cast-in-place or precast and reinforced reinforced body, and the part of the transverse annular reinforcement belt located on the top surface and the side surface of the plate body is a cast-in-place reinforced body and is cast as a whole with the hidden beam.

[0029] In order to facilitate the laying of pipelines in the floor slab, further: at least one of the transverse reinforcement belt, the longitudinal reinforcement belt and the hidden beam is internally provided with a wiring pipe.

[0030] Further: the floor slab structure further includes a ring beam around the floor slab, both ends of the reinforcement bars of the longitudinal reinforcement belt extend beyond the end surface and are connected to the ring beam, both ends of the reinforcement bars of the hidden beam extend beyond the corresponding end surfaces of the plate body and are connected to the ring beam, and the reinforcement bars of the transverse annular reinforcement belt on the side surface where the plate body contacts the ring beam extend into the ring beam.

[0031] The beneficial effects of the floor slab structure of the present invention are as follows: the floor slab structure realizes the integration of multiple functions such as structure, heat preservation, sound insulation, and fire prevention. The strengthened ALC plates are strengthened through the longitudinal reinforcement belt and the transverse annular reinforcement belt, and the shrinkage and tensile deformation of the floor slab under the action of temperature are restricted, significantly reducing the cracking risk of the plate body; at the same time, through the strengthening of the plate body, the bending and shear resistance capabilities of the plate body when bearing loads perpendicular to the plate surface are improved, and the tensile, shear, and compressive resistance capabilities of the plate body when bearing loads parallel to the plate surface are also improved, while retaining the advantages of heat preservation, heat insulation, fire prevention, etc. possessed by the plate material itself. Side grooves are respectively provided on the two sides of the splicing seam, and a reinforced body is cast-in-place in the cavity formed by the splicing of the two side grooves to form a hidden beam with reinforcement bars, which not only makes the plate bodies closely connected, improves the strength and waterproof performance at the splicing seam, but also greatly improves the integrity of the floor slab, fully meeting the stress requirements of the floor slab. The bottom surface of the floor slab has a reinforcement belt. When other equipment needs to be installed by hanging with screws, the screws can be placed in the reinforcement belt at the bottom surface of the floor slab or in the hidden beam, which can avoid the loosening and falling off of the screws. The reinforcement bars in the reinforcement belt are completely wrapped by the reinforced body, and there is no need to apply additional rust-proof paint or perform other rust-proof treatments on the reinforcement bars. Wiring pipes can also be buried in the reinforcement belt and the hidden beam and then cast-in-place. The wiring pipes are used to bury pipelines to realize pipeline integration.

[0032] The present invention also provides a wall structure, aiming to achieve the integration of thermal insulation and structure. The wall structure includes a wall formed by splicing at least two ALC boards. The board body of the ALC board has two parallel plate surfaces, as well as two end faces and two side faces. Among them, at least one ALC board is the strengthened ALC board described in the first theme above.

The two plate surfaces of the board body are respectively arranged vertically to form the two wall surfaces of the wall, and the strengthening belt is a precast or cast-in-place reinforcement body.

[0033] In order to avoid installing formwork on the wall surface of the wall and casting the strengthening belt located on the wall surface, further: the strengthening belts on the two wall surfaces of the wall are precast and are reinforcement bodies with or without reinforcement.

[0035] Further: the wall structure also includes ring beams and construction columns around the wall. The board body is provided with longitudinal strengthening belts and transverse circular strengthening belts. Both ends of the reinforcement of the longitudinal strengthening belt extend beyond the end face and are connected to the ring beam or the construction column. Both ends of the steel bars of the hidden beam extend beyond the board body and are connected to the ring beam or the construction column. The reinforcement of the transverse circular strengthening belt on the side face where the board body contacts the ring beam or the construction column extends into the ring beam or the construction column.

[0036] In order to facilitate laying pipelines in the wall, further: wiring pipes are also buried inside the strengthening belt and / or the hidden beam.

[0037] The wall structure can be used as a load-bearing wall or a self-supporting wall, and can be used as an exterior wall or an interior partition wall.

[0038] The following provides a wall structure that can be used as a load-bearing wall, specifically: reinforced ALC panels are spliced ​​together through the sides of the panel bodies to form a wall, the reinforcement belts of the two wall surfaces of the wall body are prefabricated and reinforced reinforcement bodies, the panel body is provided with a transverse annular reinforcement belt, and the reinforcement of the transverse annular reinforcement belt is annular; side grooves are provided on the sides on both sides of the splicing seam, and the center lines of the side grooves are parallel to the panel surface, and the side grooves on both sides of the splicing seam are cast-in-place grooves and correspond to each other, and the reinforcements of the transverse annular reinforcement belts of the two panel bodies on both sides of the splicing seam are intertwined in a cavity formed by splicing the two side grooves, and at least one steel bar is passed through the intertwining area, and the steel bars are arranged along the length direction of the side grooves, and the two side grooves on both sides of the splicing seam are spliced ​​to form a cast-in-place reinforcement body in the cavity to form an inner-enclosed hidden beam, and the hidden beam is arranged horizontally or vertically.

[0039] The following provides a typical wall structure that can be used as a self-supporting wall. Specifically: reinforced ALC panels are spliced ​​together through the sides of the panel bodies to form a wall. The reinforcement belts of the two wall surfaces of the wall are prefabricated reinforcement bodies. The panel bodies are provided with transverse annular reinforcement belts, and the reinforcement of the transverse annular reinforcement belts is annular. Side grooves are arranged on the sides of both sides of the splicing seam. The center lines of the side grooves are parallel to the panel surfaces. The side grooves on both sides of the splicing seam are cast-in-place grooves and correspond to each other. At least one blind hole is arranged at the bottom of the side groove on one side of the splicing seam. The reinforcement of the transverse annular reinforcement belt on the side of the other side of the splicing seam is arranged to protrude from the extension of the side. The extension is located in the blind hole. The side grooves on both sides of the splicing seam are spliced ​​to form a cast-in-place reinforcement body in the cavity and form an inner-enclosed hidden beam. The hidden beam is arranged horizontally or vertically. The panel bodies on one or both sides of the splicing seam are provided with cast-in-place holes connected to the side grooves.

[0040] In order to further strengthen the connection between the wall and the structural column, further: a concave hole is provided at the bottom of the side groove on the side where the plate body contacts the structural column, and the concave hole forms a tooth joint structure.

[0041] The beneficial effects of the wall structure of the present invention are as follows: The wall structure realizes the combination of multiple functions such as structure, heat insulation, sound insulation, and fire prevention. The reinforced ALC board is reinforced by the reinforcing belt for the board body. The reinforcing belt can be cast-in-place or precast, and can be provided with steel bars or without steel bars, which improves the ability of the wall to resist various internal forces such as tension, compression, bending, and shear generated by the load. The reinforced ALC board is strengthened by the longitudinal reinforcing belt and the transverse annular reinforcing belt. The shrinkage and tensile deformation of the wall under harsh environments such as freeze-thaw cycles, alternating wet and dry cycles, and temperature changes are restricted, significantly reducing the cracking risk of the board body; the reinforcing belt inhibits the generation of shear diagonal cracks, and the hoop restraint restricts the expansion of the cross-section around the circumference when compressed, improving the compressive strength of the material. It not only improves the flexural and shear resistance of the wall when bearing the load perpendicular to the wall surface, but also improves the tensile, shear, and compressive resistance of the wall when bearing the load parallel to the wall surface, and retains the advantages of heat insulation, fire prevention, etc. of the board itself. Side grooves are respectively provided on the two board bodies on both sides of the splicing joint. Reinforcing bars are inserted into the cavity formed by the splicing of the two side grooves and cast-in-place to form a concealed beam, which tightly connects the board bodies. This not only improves the strength and waterproof performance of the splicing joint, but also makes the board bodies tightly connected to form a wall structure with excellent integrity. Moreover, it improves the bearing capacity of the wall to resist horizontal loads such as earthquakes or winds, enabling the wall structure to meet the force requirements of being used as a load-bearing wall. The reinforcing bars intertwined and connected at the joints reduce the cracking risk of the wall under harsh environments.

[0042] The steel bars of the transverse annular reinforcing belt have extension parts protruding from the side surface. The extension parts are inserted into the blind holes. The board body is provided with cast-in-place holes communicating with the side grooves. Thus, a reinforcing body can be poured in the cavity formed by the splicing of the side grooves to form a concealed beam, and it can also achieve formwork-free pouring. When the wall structure is used as a self-supporting wall and steel bars cannot be inserted from the end face, the steel bars of the transverse annular reinforcing belt at the splicing joint can maintain good lap connection in the direction of the transverse reinforcing belt, ensuring the continuity of the steel bars in tension at the splicing joint. The wall surface of the wall structure has a reinforcing belt. When other equipment needs to be installed by hanging with screws, the screws can be placed in the reinforcing belt on the wall surface or in the concealed beam, which can prevent the screws from loosening and falling off. Wiring pipes are also buried inside the reinforcing belt and / or the concealed beam. The wiring pipes are used to bury pipelines, enabling pipeline integration.

[0043] The present invention also provides another wall structure to solve the problem of how to open doors and windows on the wall. A wall structure includes a wall, and the wall is any one of the wall structures described in the above third theme. And the wall is provided with a rectangular hole, and the hole is a door opening or a window opening, and at least one side of the hole is formed by the side surface or the end surface of the board body.

[0044] In order to improve the strength of each side of the hole, further: reinforcing bands with steel bars are respectively arranged on the side surface or the end surface of the side of the plate body forming the hole, and the reinforcing band is a cast-in-place reinforcing body, or a precast reinforcing body, or a reinforcing body with part cast-in-place and part precast.

[0045] The side of the hole is generally formed by the side surface of the plate body. Specifically: a side groove is provided on the side surface of the side of the plate body forming the hole, and a side reinforcing band is arranged in the side groove. The side reinforcing band is a precast reinforcing body with steel bars.

[0046] The beneficial effect of a wall structure of the present invention is that: by directly forming a hole serving as a door opening or a window opening through the plate body, the construction is simple and fast, and at the same time, the stress concentration parts around the hole can be strengthened.

[0056] The present invention will be further described below with reference to the drawings.

[0057] The first subject of the present invention is a reinforced ALC board, and the primary purpose is to improve the bearing capacity of the ALC board to withstand loads perpendicular to the board surface of the ALC board. As Figures 1 to 4 shown, the reinforced ALC board includes a board body 1, and the board body 1 is made of a lightweight material. The outer contour of the board body 1 is in the shape of a cuboid. The board body 1 has two parallel board surfaces, as well as two end faces and two side faces. Among them, the board surface is the face with the largest area of the board body 1, and the end face is generally the face with the smallest area. At least one reinforcing strip is provided on each board surface of the board body 1. The reinforcing strip includes at least a transverse reinforcing strip 2 and / or a longitudinal reinforcing strip 3. The two ends of the transverse reinforcing strip 2 extend to the two side faces, and the two ends of the longitudinal reinforcing strip 3 extend to the two end faces. The center line of the transverse reinforcing strip 2 is generally perpendicular to the center line of the longitudinal reinforcing strip 3, and may also be obliquely intersecting. The reinforcing strip is arranged straight, that is, the center line of the reinforcing strip is linear. When there are two or more transverse reinforcing strips 2 or longitudinal reinforcing strips 3 on a single board surface of the board body 1, the center lines of each transverse reinforcing strip 2 are preferably parallel to each other, and the center lines of each longitudinal reinforcing strip 3 are also preferably parallel to each other. For example, any two of the board surface, end face and side face of the board body 1 are perpendicular to each other. The transverse reinforcing strips 2 are parallel to each other and parallel to the end face, and the longitudinal reinforcing strips 3 are parallel to each other and parallel to the side face. The transverse reinforcing strip 2 and the longitudinal reinforcing strip 3 located on the same board surface intersect and are connected at the foot of the perpendicular, that is, the transverse reinforcing strip 2 and the longitudinal reinforcing strip 3 are integrated at the intersection. When there are three or more transverse reinforcing strips 2 or longitudinal reinforcing strips 3 on a single board surface, each transverse reinforcing strip 2 can be arranged at equal intervals, and each longitudinal reinforcing strip 3 can also be arranged at equal intervals, and local densification can be carried out according to the force requirements. In order to equally reinforce the two board surfaces of the board body 1 and avoid the need to distinguish between the two board surfaces of the board body 1, the projections of the reinforcing strips on the two board surfaces of the board body 1 on a plane parallel to the board surface coincide, that is, the arrangements of the reinforcing strips on the two board surfaces of the board body 1 are the same.

[0058] The reinforcing belt is made of a material or structure with a strength higher than that of the plate body 1. It can be precast, cast-in-place, or partially precast and partially cast-in-place. The reinforcing belt can be reinforced with steel bars, not reinforced with steel bars, or some of the reinforcing belts are reinforced with steel bars and some are not. To facilitate the cast-in-place production of the reinforcing belt, the plate body 1 is provided with a cast-in-place groove with or without steel bars at the position of the cast-in-place reinforcement body. To improve the strengthening effect, the reinforcing belt is preferably a reinforced reinforcement body. The reinforcing belt can be directly attached to the plate body 1. To facilitate the production of the reinforcing belt, grooves are provided on the surface of the plate body 1. The surface of the plate body 1 is any surface of the plate body. The reinforcing belt is entirely or partially located at the groove, and the surface of the reinforcing belt is flush with, protrudes from, or is lower than the corresponding surface of the plate body 1. To form a flat surface, the surface of the reinforcing belt is flush with the corresponding surface of the plate body 1. The groove on the surface of the plate body 1 can be of any shape in its cross-section. To facilitate the construction of the reinforcing belt and optimize the force-bearing of the reinforcing belt and ensure the reinforcement effect of the reinforcing belt, the groove on the surface of the plate body 1 is in a shape with the same size of the groove opening and the groove bottom or a shape with the groove opening larger than the groove bottom in its cross-section. For example, the groove corresponding to the longitudinal reinforcing belt 3 is trapezoidal in its cross-section, as shown in Figure 1 and Figure 2 ; or the groove corresponding to the longitudinal reinforcing belt 3 is rectangular in its cross-section, as shown in Figure 4 ; or the groove corresponding to the longitudinal reinforcing belt 3 is semi-circular in its cross-section, as shown in Figure 4 . Another example is that the side groove 4 is trapezoidal in its cross-section, as shown in Figure 5 and 6 .

[0059] The load perpendicular to the plate surface acts on the plate body 1. For example, when the plate body 1 is placed horizontally, that is, the plate surface is horizontal, and the plate body 1 is subjected to a vertical load; or when the plate body 1 is placed vertically, that is, the plate surface is vertical, and the plate body 1 is subjected to a horizontal load; one plate surface of the plate body 1 is in tension and the other plate surface is in compression. From the perspective of force, the present invention correspondingly sets reinforcing belts on the two plate surfaces of the plate body 1 respectively. The reinforcing belts strengthen the two plate surfaces respectively, improving the tensile and compressive capacities of the two plate surfaces of the plate body 1, thereby improving the capacity of the reinforced ALC plate to bear the load perpendicular to its plate surface.

[0060] The end face and side face of the plate body 1 generally need to be connected or spliced with other structures. When the reinforcing belt has steel bars, to improve the connection strength between the plate body 1 and other structures, especially to facilitate the connection with other cast-in-place structures, the two ends of the steel bars of at least one reinforcing belt are respectively extended beyond the corresponding end face or side face, that is, the steel bars of some or all of the reinforcing belts are extended beyond the corresponding end face or side face. For example, the two ends of the steel bars of the longitudinal reinforcing belt 3 are respectively extended beyond the corresponding end face of the plate body 1.

[0061] The plate bodies 1 are generally spliced through their sides, or the sides can be spliced with the end faces, and it can also be used to connect with other structures such as walls, ring beams or construction columns. When the plate bodies 1 are generally spliced through their sides, the two sides of the plate body 1 can be flat surfaces, as shown in Figure 1 or the two sides of the plate body 1 are inclined surfaces that are adapted to each other; the two sides of the plate body 1 can also be concave-convex structures that are adapted to each other, as shown in Figures 2 to 4 ; the two sides of the plate body 1 can also be other structures, for example, see Figure 5 and Figure 6 . In order to facilitate the splicing of the reinforced ALC plates into larger-area plate members by using the sides or end faces in a cast-in-place manner, at least one of the four faces, namely the two sides and the two end faces of the plate body 1, is provided with a splicing groove, and the splicing groove is a cast-in-place groove, and the center line of the splicing groove is parallel to the plate surface. For example, the sides and end faces of the plate body 1 used for splicing are both provided with splicing grooves, and the two splicing grooves enclose a closed cavity, and a reinforcing body can be poured into the cavity. The reinforcing body in each subject of the present invention is a material with better strength than that of the plate body 1. The reinforcing body directly reinforces the plate body 1 alone, or the reinforcing body is combined with the reinforcement to reinforce the plate body 1. Generally speaking, the reinforcing body is mortar, fine aggregate concrete, ceramsite concrete, cement-based grouting material, high-strength gypsum, epoxy resin grouting material, etc.

[0062] In order to give full play to the reinforcing effect of the strengthening belt on the plate body 1, avoid the separation of the strengthening belt from the plate body 1, and improve the shear resistance of the reinforced ALC plate, see Figures 5 to 9, "There is at least one group of transverse reinforcement belts 2 located on different plate surfaces and corresponding to each other. Each group consists of two transverse reinforcement belts 2. At least one group of transverse reinforcement belts 2 are connected in a loop on the side surface of the plate body 1 to form a transverse loop reinforcement belt" and / or "There is at least one group of longitudinal reinforcement belts 3 located on different plate surfaces and corresponding to each other. Each group consists of two longitudinal reinforcement belts 3. At least one group of longitudinal reinforcement belts 3 are connected in a loop on the end surface of the plate body 1 to form a longitudinal loop reinforcement belt". That is to say, the transverse reinforcement belts 2 on different plate surfaces can be connected in a loop, or the longitudinal reinforcement belts 3 on different plate surfaces can be connected in a loop, or the transverse reinforcement belts 2 on different plate surfaces and the longitudinal reinforcement belts 3 on different plate surfaces can be connected in a loop respectively; all the transverse reinforcement belts 2 on two plate surfaces can be connected in a loop, or only some of the transverse reinforcement belts 2 can be connected in a loop, and the remaining transverse reinforcement belts 2 are in a straight strip shape; similarly, all the longitudinal reinforcement belts 3 on different plate surfaces can be connected in a loop, or only some of the longitudinal reinforcement belts 3 can be connected in a loop, and the remaining longitudinal reinforcement belts 3 are in a straight strip shape. The part of the transverse loop reinforcement belt located on the side surface of the plate body 1 is the same as the part located on the plate surface of the plate body 1. The part of the longitudinal loop reinforcement belt located on the end surface of the plate body 1 is the same as the part located on the plate surface of the plate body 1. In order to ensure the hoop restraint effect of the transverse loop reinforcement belt and the longitudinal loop reinforcement belt, both the transverse loop reinforcement belt and the longitudinal loop reinforcement belt are preferably precast, cast-in-place, or partially precast and partially cast-in-place reinforcing bodies, and the reinforcing body has a ring-shaped steel reinforcement.

[0063] The transverse loop reinforcement belt and the longitudinal loop reinforcement belt play a role of a hoop. The transverse loop reinforcement belt mainly plays a role of hoop restraint on the whole formed by the longitudinal reinforcement belt 3 and the plate body 1. The longitudinal loop reinforcement belt mainly plays a role of hoop restraint on the transverse reinforcement belt 2. Both the transverse loop reinforcement belt and the longitudinal loop reinforcement belt can prevent the separation of the reinforcement belt and the plate body 1 and inhibit the generation of shear inclined cracks. When under compression, on the cross-section perpendicular to the pressure, the expansion around the periphery of the reinforced ALC board is hoop-restrained, and the compressive strength of the material is increased. This not only improves the flexural and shear resistance of the plate body 1 when bearing the load perpendicular to the wall surface, but also improves the tensile, shear, and compressive resistance of the plate body 1 when bearing the load parallel to the wall surface, so that the reinforced ALC board can be used as a floor slab or a load-bearing wall. The plate body 1 of the reinforced ALC board is generally a strip board, that is, the area of the plate surface is greater than or much greater than the area of the side surface, and the area of the side surface is greater than or much greater than the area of the end surface. According to the structural characteristics of the reinforced ALC board with the plate body 1 being a strip board, the outer contour of the plate body 1 is in the shape of a cuboid, see Figure 7 , Figure 11 and 12, The typical strengthening method of the reinforced ALC board is as follows: longitudinal strengthening belts 3 are respectively arranged on the two board surfaces of the board body 1, each longitudinal strengthening belt 3 is parallel to each other and parallel to the side surface, and the steel bars of the longitudinal strengthening belt 3 extend beyond the end surface to facilitate connection with other structures; transverse strengthening belts 2 are also respectively arranged on the two board surfaces of the board body 1, each transverse strengthening belt 2 is parallel to each other and perpendicular to the longitudinal strengthening belt 3, the transverse strengthening belts 2 on the two board surfaces correspond to each other, the transverse strengthening belt 2 and the longitudinal strengthening belt 3 intersect and are connected at the foot of the perpendicular, and two transverse strengthening belts 2 on different board surfaces and corresponding to each other are connected into a ring on the side surface of the board body 1 to form a transverse ring-shaped strengthening belt.

[0064] The following provides another type of reinforced ALC board, mainly to improve the ability of the board body to bear the load perpendicular to the side surface. See Figure 15 For the reinforced ALC board placed horizontally on the upper part, the board body 1 of the reinforced ALC board is a strip board. In order to improve the ability of the reinforced ALC board to bear the load perpendicular to the side surface of the board body 1, a transverse ring-shaped strengthening belt is arranged on the board body 1, and the steel bars of the transverse ring-shaped strengthening belt are in a ring shape; longitudinal strengthening belts 3 are arranged on the board body 1, and the steel bars of the longitudinal strengthening belt 3 extend beyond the end surface; side strengthening belts 5 are arranged on both side surfaces of the board body 1, the side strengthening belt 5 intersects and is connected with the transverse ring-shaped strengthening belt, the side strengthening belt 5 is a reinforcing body with steel bars, all of the reinforcing bodies of the side strengthening belt 5 are precast, or all are cast-in-place, or part are precast and part are cast-in-place, and the steel bars of the side strengthening belt 5 extend beyond the end surface. In order to facilitate the casting of the side strengthening belt 5, side grooves 4 can be arranged on the side surface, and the side strengthening belt 5 is located in the side groove 4.

[0065] Reinforced ALC boards often need to be spliced into larger board members. The reinforced ALC boards can be spliced by end surface and side surface, or side surface and side surface, or end surface and side surface. The reinforced ALC boards are generally spliced through the side surface. The following takes the splicing of the board body 1 through the side surface as an example for description. For the board body 1 spliced through the side surface, both side surfaces of the board body 1 may be used for splicing with the board body 1, or only one side surface may be used for splicing with the board body 1. For the reinforced ALC board with only one side surface used for splicing, one side surface is the splicing side surface, and the other side surface is the non-splicing side surface. The non-splicing side surface may directly form an end surface, or may be cast-in-place and connected with other structures. In order to facilitate the splicing of the board bodies 1 by the cast-in-place method, side grooves 4 are arranged on the side surface used for splicing. The side groove 4 is a cast-in-place groove, and the center line of the side groove 4 is parallel to the board surface; the board body 1 is also provided with a transverse ring-shaped strengthening belt, the steel bars of the transverse ring-shaped strengthening belt are in a ring shape, and the steel bars of the transverse ring-shaped strengthening belt in the side groove 4 used for splicing protrude from this side surface. See Figure 5On the left side, it makes the splicing of the plate bodies 1 more stable. When the non-spliced side surfaces of the plate bodies 1 form end faces, in order to reinforce the non-spliced side surfaces, side strengthening belts 5 are arranged on the non-spliced side surfaces. The side strengthening belts 5 are reinforcing bodies with steel bars. The side strengthening belts 5 can be precast, cast-in-place, or partially precast and partially cast-in-place. In order to facilitate the production of the side strengthening belts 5, side grooves 4 are arranged on the non-spliced side surfaces of the plate bodies 1. The side strengthening belts 5 are located in the side grooves 4 and are flush with the non-spliced side surfaces, as Figure 5 shown. When the non-spliced side surfaces of the plate bodies 1 are cast-in-place and connected to other structures, transverse ring-shaped strengthening belts are arranged on the plate bodies. The steel bars of the transverse ring-shaped strengthening belts protrude from the non-spliced side surfaces. For example, see Figure 5 and Figure 9 . The steel bars in the side grooves 4 on the left side of the plate body 1 protrude from the side surface, which is beneficial to the stable connection between the left side surface of the plate body 1 and other structures.

[0066] For the reinforced ALC plates where only two side surfaces are used for splicing with other plate bodies 1, in order to insert steel bars and perform cast-in-place connection after splicing the two spliced plate bodies 1, and improve the integrity and seismic resistance of the plate bodies 1 after splicing, see Figure 6 and Figure 9 . Transverse ring-shaped strengthening belts are arranged on both side surfaces of the plate body 1. The steel bars of the transverse ring-shaped strengthening belts are annular. Side grooves 4 are arranged on both side surfaces of the plate body 1. The center lines of the side grooves 4 are parallel to the plate surfaces. Both side grooves 4 are cast-in-place grooves and correspond to each other. The steel bars of the transverse ring-shaped strengthening belts in the two side grooves 4 protrude from the side surfaces, and the height of the protruding steel bars from the side surfaces is not greater than the depth of the side grooves 4. After the two plate bodies 1 are spliced through the side surfaces, the side grooves 4 on both sides of the splicing joint are spliced to form a cavity. The steel bars of the transverse ring-shaped strengthening belts are intertwined in the cavity formed by the splicing of the two side grooves 4. One or more steel bars are inserted from the end face of the plate body 1 into the intertwined area. The steel bars are arranged along the length direction of the side grooves 4, and a reinforcing body is poured into the cavity, and an embedded hidden beam 7 can be formed between the two plate bodies 1.

[0067] After the two plate bodies 1 are spliced through the side surfaces, when the end face is blocked and steel bars cannot be inserted and a reinforcing body is poured into the cavity formed by the splicing of the two side grooves 4 through the end face, in order to improve the connection strength between the plate bodies 1, see Figure 10, the plate body 1 is provided with a transverse annular reinforcement belt, and side grooves 4 are respectively provided on the two sides of the plate body 1. The two side grooves 4 are cast-in-place grooves and correspond to each other. At least one blind hole 6 is provided at the bottom of one side groove 4, and the reinforcement of the transverse annular reinforcement belt on the other side is provided with an extension protruding from the side, and the extension corresponds to the blind hole 6. After the two plate bodies 1 are spliced ​​through the side, the extension of the reinforcement of the transverse annular reinforcement belt is directly inserted into the blind hole 6. After the reinforcement body is cast in the cavity formed by the splicing of the two side grooves 4, the blind hole 6 is filled with the reinforcement body to form a structure equivalent to a tooth joint, so as to achieve a stable connection between the plate bodies 1. In order to improve the cast-in-place splicing strength of the reinforced ALC board or the integrity with other cast-in-place structures, the reinforcement of the transverse annular reinforcement belt protrudes from the side with the blind hole 6, and the height of the reinforcement protruding from the side is not greater than the depth of the side groove 4.

[0068] Whether the side of the plate body 1 is cast-in-place spliced ​​with other plate bodies 1 or with other structures, the reinforcement of the transverse annular reinforcement belt on the side of the cast-in-place splicing is preferably protruding from the side, so that the reinforcement of the transverse annular reinforcement belt can extend more into the cast-in-place reinforcement body, thereby improving the connection strength. For the side of the plate body 1 cast-in-place spliced ​​with other plate bodies 1, the height of the reinforcement of the transverse annular reinforcement belt protruding from the side is not greater than the depth of the side groove 4, so as to avoid the problem that the plate body 1 cannot be spliced.

[0069] The second subject of the present invention is a floor structure. Figures 7 to 9 The floor structure includes at least two reinforced ALC panels described in the first subject above, each panel 1 is spliced ​​together through the side to form a floor, a splicing seam is formed between the panels 1, one panel surface of the panel 1 forms the top surface of the floor, and the other panel surface forms the bottom surface of the floor, and the reinforcement belt of the panel 1 includes a transverse reinforcement belt 2 and a longitudinal reinforcement belt 3, and the reinforcement belt is a prefabricated or cast-in-place reinforcement body with reinforcement. When the reinforcement belt is cast-in-place, before casting, the panel 1 can be provided with a cast-in-place groove with reinforcement along the reinforcement belt to facilitate cast-in-place construction.

[0070] In order to ensure the strength of the reinforced ALC board, to ensure the strength of the floor structure, such as Figures 7 to 9 As shown, the transverse reinforcement belts 2 on the two plate surfaces of the plate body 1 are connected to form a ring on the side of the plate body 1, and form a transverse ring-shaped reinforcement belt, and the reinforcement of the transverse ring-shaped reinforcement belt is ring-shaped.

[0071] In order to make the plate bodies 1 more stable after being spliced side by side, side grooves 4 are provided on both sides of the splicing seam. The center line of the side groove 4 is parallel to the plate surface. The side grooves 4 on both sides of the splicing seam are all cast-in-place grooves and correspond to each other. The steel reinforcements of the transverse annular strengthening belts of the two plate bodies 1 on both sides of the splicing seam are intertwined in the cavity formed by the splicing of the two side grooves 4. At least one steel bar is inserted in the intertwined area, and the steel bar is arranged along the length direction of the side groove 4. A reinforcing body is cast-in-place in the cavity formed by the splicing of the two side grooves 4 on both sides of the splicing seam to form an inner-encased hidden beam 7. For example, see Figure 9 , four steel bars are inserted in the intertwined area, and the four steel bars and the steel reinforcements of the transverse annular strengthening belt form a columnar steel cage structure, and the steel cage structure becomes the steel reinforcement of the hidden beam 7.

[0072] For the convenience of construction and to realize the formwork-free construction of the cast-in-place part of the floor slab structure, the strengthening belt at the bottom of the floor slab is a precast and reinforced reinforcing body; the longitudinal strengthening belt 3 on the top surface of the floor slab does not affect the pouring of the hidden beam 7, so it can be precast and have a reinforced reinforcing body, and of course it can also be cast-in-place and have a reinforced reinforcing body; the part of the transverse annular strengthening belt located on the top surface of the floor slab and the side of the plate body 1 is a cast-in-place reinforcing body and is cast-in-place synchronously with the hidden beam 7, thus becoming an integral whole. The hidden beam 7 can be completely inner-encased, that is, the plate bodies 1 are tightly spliced at the top and bottom surfaces of the floor slab, and the side grooves 4 at the end faces of the plate bodies 1 serve as the pouring entrances of the hidden beam 7; or the part of the transverse annular strengthening belt located on the top surface of the floor slab can be used as the pouring entrance of the hidden beam 7, because the transverse annular strengthening belt is connected and communicated with the side groove 4 on the side of the plate body; the hidden beam 7 can also be partially inner-encased, that is, the plate bodies 1 are tightly spliced at the bottom surface of the floor slab, and the plate bodies 1 leave gaps at the top surface of the floor slab for convenient cast-in-place construction.

[0073] Since the part of the transverse annular strengthening belt located on the top surface of the floor slab, the longitudinal strengthening belt 3 and the hidden beam 7 can all be cast-in-place without formwork, in order to facilitate the laying of pipelines in the floor slab and realize pipeline integration, wiring pipes 8 can be buried in at least one of the three positions of the transverse strengthening belt 2, the longitudinal strengthening belt 3 and the hidden beam 7 first and then cast-in-place, where the wiring pipes 8 are used for burying pipelines. For example, the wiring pipes 8 are PVC pipes.

[0074] The sides of the plate bodies 1 are spliced with each other and the perimeter of the floor slab formed is placed on the wall or beam. See Figure 7 , the floor slab structure also includes a ring beam 9 around the floor slab. The two ends of the steel reinforcement of the longitudinal strengthening belt 3 extend beyond the end face and are connected to the ring beam 9. The two ends of the steel bars of the hidden beam 7 extend beyond the corresponding end faces of the plate bodies 1 and are connected to the ring beam 9. The steel reinforcement of the transverse annular strengthening belt on the side of the plate body 1 in contact with the ring beam 9 extends into the ring beam 9 to realize effective connection of the entire perimeter of the floor slab with the ring beam 9.

[0075] The third subject matter of the present invention is a wall structure. The wall structure includes a wall formed by splicing at least two ALC boards. The board body 1 of the ALC board has two parallel board surfaces, as well as two end faces and two side faces, and at least one ALC board is the strengthened ALC board described in the first subject matter above. That is to say, the wall can be spliced by existing ALC boards and the strengthened ALC boards described in the first subject matter above, or can be completely spliced by the strengthened ALC boards described in the first subject matter above. The splicing method of the wall is that "the side faces of each board body 1 are spliced with each other" and / or "the side face of each board body 1 is spliced with the end face", and a splicing seam is formed between the board bodies 1. The two sides of the splicing seam are respectively a side face and a side face, or a side face and an end face. The two board surfaces of the board body 1 are respectively arranged vertically to form two wall surfaces of the wall, and the side faces of the board body 1 are arranged horizontally or vertically. For example, in Figure 11 and Figure 13 In the illustrated embodiment, the side faces of each board body 1 are spliced with each other, and the side faces of the board body 1 are all arranged horizontally; in Figure 12 and Figure 14 In the illustrated embodiment, the side faces of each board body 1 are spliced with each other, and the side faces of the board body 1 are all arranged vertically; in Figure 15 In the illustrated embodiment, the side face of the board body 1 is spliced with the end face. The strengthening belts on the two wall surfaces of the wall are precast or cast-in-place reinforcing bodies. Since the board surfaces of the board body 1 are arranged vertically, if the strengthening belt located on the board surface is constructed by casting in place, formwork support is required, and the construction is relatively cumbersome. Therefore, the strengthening belt located on the board surface is preferably a precast reinforcing body. The strengthening belts on the two wall surfaces of the wall are reinforcing bodies with or without reinforcement bars, and whether to be reinforced is determined according to the force on the wall. For example, the strengthening belts on the two wall surfaces of the wall are precast and have reinforcing bodies with or without reinforcement bars.

[0076] In order to splice the wall by casting in place to ensure the strength and waterproofness of the splicing seam, splicing grooves are respectively arranged on the side faces or end faces on both sides of the splicing seam. The splicing grooves on both sides of the splicing seam correspond to each other, and a cavity formed by splicing the splicing grooves on both sides of the splicing seam is cast with a reinforcing body to form an in-built hidden beam 7. The hidden beam 7 is arranged horizontally or vertically, and steel bars can be placed or not placed in the hidden beam 7.

[0077] Generally, the perimeter of the wall structure is a ring beam 9 and a construction column 10, see Figures 11 to 13, the plate body 1 is provided with longitudinal reinforcement bands 3 and transverse annular reinforcement bands. The longitudinal reinforcement bands 3 and the transverse annular reinforcement bands intersect and are connected on the plate surface. Both ends of the reinforcement bars of the longitudinal reinforcement bands 3 extend beyond the end faces and are connected to the ring beam 9 or the structural column 10; when there is a hidden beam 7 with reinforcement bars at the splicing joint, both ends of the reinforcement bars of the hidden beam 7 extend beyond the plate body 1 respectively and are connected to the ring beam 9 or the structural column 10; the reinforcement bars of the transverse annular reinforcement bands on the side surface where the plate body 1 contacts the ring beam 9 or the structural column 10 extend into the ring beam 9 or the structural column 10. In order to further strengthen the connection between the wall body and the structural column 10, concave holes 11 forming a dovetail structure are arranged on the side surface or the end face where the plate body 1 contacts the structural column 10. The concave holes 11 can be one or more, such as Figure 15 as shown.

[0078] In order to facilitate the laying of pipelines in the wall body and realize pipeline integration, wiring pipes 8 can be buried inside the reinforcement bands and / or the hidden beam 7 first. Among them, the wiring pipes 8 are used for burying pipelines. For example, the wiring pipes 8 are PVC pipes.

[0079] When the wall body does not need to be provided with doors and windows, the side surfaces of each plate body 1 are suitable for splicing with each other; when the wall body needs to be provided with doors and windows, the side surfaces of each plate body 1 are suitable for splicing with the end faces, or the side surfaces of each plate body 1 are spliced with each other and the side surfaces are spliced with the end faces. When there is splicing between the side surface and the end face of the plate body 1 in the wall structure, in order to realize stable splicing between the side surface and the end face, splicing grooves are respectively arranged on the side surface and the end face on both sides of the splicing joint. The splicing grooves on both sides of the splicing joint correspond to each other, and the splicing structure and method between the side surface and the end face are the same as the splicing structure and method between the side surfaces in the present invention. For example, see Figure 15 , splicing grooves are respectively arranged on the side surface and the end face, and a reinforcing body is cast in situ in the cavity formed by the splicing of the splicing grooves to form an inner-encased hidden beam 7.

[0080] The wall structure can be used as a load-bearing wall or a self-load-bearing wall, and can be used as an exterior wall or an interior partition wall. There are different construction restrictions when the wall structure is used as a load-bearing wall and a self-load-bearing wall. When the wall structure is used as a load-bearing wall and the side surface of the plate body 1 is arranged vertically, there is no obstacle at one end face of the plate body 1; when the wall structure is used as a non-load-bearing wall and the side surface of the plate body 1 is arranged vertically, there are obstacles at both end faces of the plate body 1.

[0081] When the wall structure is used as a load-bearing wall, the splicing method between the reinforced ALC plates can be the same as the splicing method between the strong ALC plates in the floor structure described in the above second theme.

[0082] It is assumed that the plate body 1 is spliced ​​through the side. When the plate body 1 has an end face without any obstruction, for example, when the wall structure is used as a load-bearing wall, the reinforced ALC panels are spliced ​​with each other through the sides of the plate body 1 to form a wall. The reinforcement belts of the two wall surfaces of the wall are prefabricated and reinforced reinforcement bodies. The plate body 1 is provided with a transverse annular reinforcement belt, and the reinforcement of the transverse annular reinforcement belt is annular. Side grooves 4 are arranged on the sides on both sides of the splicing seam, and the center lines of the side grooves 4 are parallel to the plate surface. The side grooves 4 on both sides of the splicing seam are cast-in-place grooves, and the side grooves 4 on both sides of the splicing seam correspond to each other. The side grooves 4 on both sides of the joint are spliced ​​to form a columnar cavity. The reinforcement of the transverse annular reinforcement belts of the two plate bodies 1 on both sides of the splicing seam is interwoven with each other in the cavity formed by the splicing of the two side grooves 4. At least one steel bar is passed through the interwoven area, and the steel bars are arranged along the length direction of the side grooves 4. The two side grooves 4 on both sides of the splicing seam are spliced ​​together to form a cast-in-place reinforcement body in the cavity formed and form an inner-wrapped hidden beam 7. The interwoven reinforcement and the passed steel bars form a steel cage of the hidden beam 7, and the hidden beam 7 is arranged horizontally or vertically.

[0083] It is assumed that the plate body 1 is spliced ​​through the side. When there are obstacles on both end faces of the plate body 1, for example, when the wall structure is used as a non-load-bearing wall, and the two end faces of the plate body 1 are blocked by beams and floor slabs respectively, the reinforced ALC plate is spliced ​​with each other through the side of the plate body 1 to form a wall. The reinforcement belts of the two wall surfaces of the wall are prefabricated reinforcement bodies. The plate body 1 is provided with a transverse annular reinforcement belt, and the reinforcement of the transverse annular reinforcement belt is annular. Side grooves 4 are arranged on the sides of both sides of the splicing seam. The center line of the side groove 4 is parallel to the plate surface. The side grooves 4 on both sides of the splicing seam are cast-in-place grooves and correspond to each other. At least one blind hole 6 is arranged at the bottom of the side groove 4 on one side of the splicing seam. The reinforcement of the transverse annular reinforcement belt on the side of the other side of the splicing seam is arranged to protrude from the extension of the side. The extension is located in the blind hole 6. The blind hole 6 forms a structure similar to a horse tooth joint. The side grooves 4 on both sides of the splicing seam are spliced ​​to form a cast-in-place reinforcement body in the cavity and form an internally enclosed hidden beam 7. The hidden beam 7 is arranged horizontally or vertically. See. Figure 10 In order to realize the cast-in-place construction of the hidden beam 7, the plate body 1 on one side or both sides of the joint is provided with a cast-in-place hole connected to the side groove 4.

[0084] The reinforcement of the transverse annular reinforcement belt has an extension part protruding from the side, and the extension part is inserted into the blind hole 6. The plate body 1 is provided with a cast-in-place hole connected to the side groove 4, so that the reinforcement body can be cast in the cavity formed by splicing the side grooves 4 and a hidden beam 7 can be formed. It can also achieve formwork-free casting. When the wall structure is used as a self-supporting wall and the steel bars cannot be inserted from the end face, the reinforcement of the transverse annular reinforcement belt at the joint can maintain good overlap and connection of the steel bars in the direction of the transverse reinforcement belt 2, ensuring the continuity of the steel bars under tension at the joint. When the wall surface of the wall structure has a reinforcement belt and other equipment needs to be suspended and installed by screws, the screws can be placed in the reinforcement belt of the wall surface, or in the hidden beam 7, to prevent the screws from loosening and falling off.

[0085] The fourth subject of the present invention is a wall structure, which solves the problem of how to open doors and windows on the wall. As Figure 15 shown, a wall structure includes a wall, which is any one of the wall structures described in the above-mentioned third subject, and the wall is provided with a rectangular hole, which is a door hole or a window hole, and the hole is formed by at least one side of the plate body 1 from the side or end face of the plate body 1. By splicing plate bodies of different sizes to form the hole, the construction is simple and fast. The hole is generally rectangular and has four sides. In order to facilitate the installation of doors and windows, a reinforced belt with reinforcement is respectively arranged on the side or end face of the side of the plate body 1 forming the hole.
