DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0027] In this specification, the terms "vertical", "lateral", "longitudinal", "up", "down", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0028] The ALC board joint structure disclosed in the present invention is as follows: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the bottom end of the ALC board extends to the structural board 6, and the top end extends to the structural beam 7, and two adjacent ALC boards form a joint; of the two adjacent ALC boards forming the joint, one is the left side board 8, and the other is the right side board 9; along the extension direction of the joint, several sets of joint connection systems 1 are distributed at intervals on the joint, and each set of joint connection systems 1 includes connecting steel bars 11, steel bar grouting holes 12, steel mesh 13 and mesh grouting grooves 14; the left side of the mesh grouting groove 14 extends transversely along the joint to the left side board 8, and the right side of the mesh grouting groove 14 extends transversely along the joint to the right side board 9, and the steel mesh 13 covers the bottom of the mesh grouting groove 14 in the transverse direction, that is, the steel mesh 13 spans between the left side board 8 and the right side board 9, and when the mesh grouting groove 14 is filled with slurry and solidified, the slurry and the steel mesh 13 are solidified into a whole, thereby connecting the left side board 8 and the right side board 9 together in the transverse direction. The steel bar grouting hole 12 extends transversely along the joint, with its left end extending into the left side plate 8 and its right end extending into the right side plate 9. The connecting steel bar 11 is arranged in the steel bar grouting hole 12, that is, the connecting steel bar 11 spans between the left side plate 8 and the right side plate 9. When the steel bar grouting hole 12 is filled with slurry and solidified, the slurry and the connecting steel bar 11 are consolidated into a whole, thereby connecting the left side plate 8 and the right side plate 9 together in the transverse direction. The steel bar grouting hole 12 is connected to the mesh grouting groove 14. In this way, when pouring slurry, the steel bar grouting hole 12 and the mesh grouting groove 14 can be poured at the same time. In this way, the slurry, the connecting steel bar 11 and the wire mesh 13 are consolidated into a whole, and the left side plate 8 and the right side plate 9 are jointly connected, and the connection strength is significantly improved.

[0029] In order to further strengthen crack control, a concave slot is provided on one side of the left plate 8 where the joint is formed. The slot is vertically penetrated, and a vertically extending grouting pipe 3 is provided in the slot. The mesh grouting grooves 14 of each set of joint connection systems 1 are connected through the grouting pipe 3, and a grouting hole 5 connected to the grouting pipe 3 is provided at the bottom of the grouting pipe 3; after the slurry that fills the grouting pipe 3, the mesh grouting groove 14 and the steel bar grouting hole 12 solidifies, several sets of joint connection systems 1 are connected as a whole. The slurry is injected from the grouting pipe 3, and it fills each set of joint connection systems 1 and the grouting pipe 3 from bottom to top in sequence, so that a vertical column is formed vertically along the grouting pipe 3 to connect several sets of joint connection systems 1, forming a horizontal and vertical integrated structure to strengthen the joints, effectively avoiding the quality problem of cracking of the plate seams at the joints of the ALC strip board.

[0030] Preferably, the steel mesh 13 is laid horizontally on the bottom of the mesh grouting groove 14, and the connecting steel bar 11 is vertically arranged above the steel mesh 13. Of course, the connecting steel bar 11 can also be placed at the bottom and the steel mesh 13 at the top. However, if the steel mesh 13 is directly laid on the bottom of the mesh grouting groove 14, the contact area between the steel mesh 13 and the bottom of the mesh grouting groove 14 is larger, which is more conducive to flattening the steel mesh 13, and the connecting steel bar 11 is pressed on the steel mesh 13, which can avoid the position of the steel mesh 13 from changing to a certain extent during grouting.

[0031] In order to further enhance the crack control performance of each set of joint connection system 1, a connecting steel bar 11 is respectively provided on both sides of the front and rear of the wire mesh 13 along the longitudinal direction of the joint. Compared with only one connecting steel bar 11, the tensile strength of the joint connection system 1 obtained after the two connecting steel bars 11 are cast is improved, which is more conducive to preventing cracks in the plate joints.

[0032] In order to discharge the air in the hole during grouting, an exhaust hole 15 is provided at the end of the steel bar grouting hole 12 in the transverse direction. The exhaust hole 15 passes through the back of the ALC board in the longitudinal direction and is located at the top of the steel bar grouting hole 12 in the vertical direction.

[0033] In order to achieve reliable installation of the ALC board, a top connection system 2 is provided between the top of the joint and the structural beam 7. Figure 3 As shown, the top connection system 2 includes a top reserved groove 21 set at the top of the joint and a steel anchor 22 installed on the structural beam 7 in the top reserved groove 21. The grouting pipe 3 is connected to the top reserved groove 21, and the grout filled in the top reserved groove 21 is solidified into one with the steel anchor 22. The top reserved groove 21 extends to the structural beam 7 along the vertical top; the top reserved groove 21 extends to the left side plate 8 along the horizontal left end, and the left end extends to the right side plate 9. When concrete is poured into the top reserved groove 21, after the concrete solidifies, it straddles the joint between the left side plate 8 and the right side plate 9, with one end inserted into the left side plate 8 and the other end inserted into the right side plate 9, playing the role of a connector, and the steel anchor 22 fixed to the structural beam 7 is solidified in the concrete, thereby achieving a reliable connection between the top of the ALC board and the structural beam 7, and avoiding the problem of cracks at the top of the ALC board.

[0034] A bottom grouting groove 4 is provided at the bottom end of the joint, the bottom grouting groove 4 is connected to the grouting pipe 3, and the bottom grouting groove 4 is filled with grouting liquid; the bottom grouting groove 4 extends to the structural plate 6 along the vertical bottom end; the bottom grouting groove 4 extends to the left plate 8 along the horizontal left end, and the left end extends to the right plate 9. Similar to the top end, after the concrete poured into the bottom grouting groove 4 solidifies, the left plate 8 and the right plate 9 are connected at the bottom end, which can avoid the problem of cracks at the bottom end of the ALC plate. Moreover, after the concrete poured into the bottom grouting groove 4 solidifies, the bottom end of the concrete column formed in the grouting pipe 3 forms an enlarged base, which improves the stability and reliability of the concrete column to a certain extent.

[0035] The construction method of the ALC board joint structure comprises the following steps:

[0036] ALC board processing:

[0037] Slots for forming steel bar grouting holes 12, mesh grouting grooves 14, top reserved grooves 21 and bottom grouting grooves 4 are provided on the left side plate 8 and the right side plate 9, and exhaust holes 15 are provided on the corresponding external sides;
