[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0022] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1 Example 1 of this specification provides a construction method for using ALC board for roof flower rack concrete lattice column, please refer to Figure 1 As shown, including: S1. Draw the positioning line: Draw the positioning line to determine the installation position of the ALC board; It should be noted that before installation, clean the base, locate the ALC board installation position and draw the positioning line, and then use a twist drill to drill a hole at the pipe clamp insertion position 80mm from the board end. The line drawing positioning method can be traditional line drawing. For example, use a laser level to locate the position of the ALC board on the floor / concrete beam, and use a 14mm twist drill to drill a hole at the pipe clamp insertion position 80mm from the board end.

[0024] S2. Installation of the first ALC board: after determining that the moisture content of the first ALC board is within the specified threshold, the first ALC board is hoisted, and the first pipe clamps are respectively inserted into the bottom and top of the first ALC board, and the first ALC board is installed to the corresponding positioning line, and the two first pipe clamps are respectively connected to the steel beam and the floor slab; In a possible implementation, the pipe clamp is made of Q235B galvanized material with a minimum thickness of 1.5mm. Before installation, clean the base. When installing the pipe clamp, insert the pipe clamp at a position 80mm away from the side of the plate end. When installing, first insert the pipe clamp into the corresponding hole along the thickness direction of the ALC plate, and then use a plate erector to erect the strip plate and install it to the positioning line.

[0025] It is further explained that the specifications and tools of the connectors should be checked before installation; during installation, the plate should be positioned before installation to ensure that there is no interference with the steel bars in the plate; after installation, check whether there are cracks around the plate installation position and whether the connectors are loose. The moisture content of the ALC plate should be tested before erection and should be controlled within 30%.

[0026] When hoisting, fix one end of the sling to the hook of the winch, and wrap the other end around the wall panel (the panel refers to the ALC panel), and lift the wall panel by the winch. Before installing the wall panel, the working surface and the panel must be cleaned, and no dust, oil or other debris should be allowed. Smear the ALC special adhesive in the mother-and-child groove on the side of the installed wall panel, and the mortar in the groove must not be less than half of the groove depth. If mortar falls to the ground, it is strictly forbidden to use it again. The adhesive joint is generally not lower than 4~5 mm below the board surface, making the joints between the wall panels smoother and firmer. The pipe clamp is fixed to the structure by nails, and a single pipe clamp uses 2 nails.

[0027] S3, installation of the second ALC board: apply adhesive to the bonding side of the first ALC board, make sure the moisture content of the second ALC board is within the specified threshold, then lift the second ALC board, insert the second pipe clamps at the bottom and top of the second ALC board respectively, bond the second ALC board to the first ALC board and squeeze the slurry. After squeezing, the vertical seam width must be within the threshold, and connect the two second pipe clamps to the steel beam and the floor slab respectively; In a possible implementation, the installation method is basically the same as the first ALC board, except that a crowbar is used as an aid to push the second ALC board toward the installed board (the first ALC board); the adhesive is squeezed out from the board gaps to ensure that the vertical gap width is about 5mm after squeezing, and the upper and lower vertical gap widths are consistent to ensure the bonding force between the wall panels. Mortar should be scraped on both sides of the ends of the installed board, and the groove of the installed board (the second ALC board) should be half filled with mortar. Mortar should not be scraped on both sides of the ends of the installed board to prevent it from falling off during transportation, erection, and installation; manual squeezing methods can be used for boards with lower heights, and crowbars, straps, etc. can be used for large boards to ensure uniform force; after squeezing, the board should be fixed in time, and the squeezing effect should be checked. If there is a cavity, it should be repaired immediately.

[0028] It should be noted that the thickness of the mortar scraped during the slurry squeezing operation must be strictly guaranteed to ensure the density of the bonding mortar; the boards must not be freely fitted into place, and a crowbar or straps (for larger boards) must be used to bring the two boards close together to ensure uniform slurry squeezing; in order to ensure compatibility and the quality of the wall panel joints, the board joint bonding mortar must use ALC special bonding mortar, which must not be mixed or replaced.

[0029] S4, adhesive filling, using auxiliary equipment to make gaps between the top and bottom of the first ALC board and the second ALC board and the steel beam and the floor slab respectively, and fill the gaps with adhesive; In a possible implementation, clean the working surface at the bottom of the ALC board, place two triangular wooden wedges or rubber pads on each side of the wallboard as temporary fixation of the wallboard, and the gaps at the top and bottom of the board are 1 to 2 cm. When erecting the board, it is advisable to use a winch or a car crane to improve the installation efficiency and ensure the safety of the wallboard installation. Use a narrow putty knife to push the adhesive until it overflows from the other side of the bottom board seam; use a putty knife to smooth both sides. The gap at the bottom of the board after filling must be full without omission to prevent cracking caused by board settlement; when the mortar reaches the strength, remove the wooden wedges and use the same special adhesive to repair the position of the wooden wedges. If a rubber pad is used, it can be completed in one go.

[0030] It should be noted that the board and process should be reviewed according to the construction drawings before installation; during the installation process, the same point on the board needs to be positioned twice to ensure the verticality of the board and check whether the amount of mortar is sufficient; after the installation is completed, check whether the grouting and mortar are full and whether they meet the process requirements.

[0031] After the adhesive reaches the hardness requirement, the construction is completed.

[0032] It should be noted that if Figure 2 As shown, when the board length is ≤4m, the bottom of the strip board does not need to be fixed; Figure 3 As shown, when the plate length is greater than 4m, a pipe clamp is set at the bottom. The pipe clamp is made of Q235B galvanized material with a minimum thickness of 1.2mm.

[0033] Example 2 Example 2 of this specification provides an ALC board for a roof flower stand concrete lattice column device, please refer to Figure 4 and Figure 5 As shown, it includes a first ALC board 1 and a second ALC board 2, and the first ALC board and the second ALC board are connected by an adhesive; a sub-groove 3 is provided on the side of the first ALC board 1, and a mother groove 4 matching the sub-groove is provided on the side of the second ALC board 2; the top and bottom of the first ALC board are respectively plugged with a first pipe clamp 5, and the top and bottom of the first ALC board are respectively connected to the steel beam A and the floor slab B through the first pipe clamp, and the top and bottom of the first ALC board are respectively provided with an adhesive; the top and bottom of the second ALC board are respectively plugged with a second pipe clamp 6, and the top and bottom of the second ALC board are respectively connected to the steel beam and the floor slab through the second pipe clamp, and the top and bottom of the second ALC board are respectively provided with an adhesive.

[0034] Preferably, the first pipe clamp (the first pipe clamp and the second pipe clamp have the same structure, collectively referred to as pipe clamps herein) is a T-shaped structure, including a bottom plate 51 and a column 52 disposed on the bottom. The adhesive includes mortar.

[0035] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0036] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
