[0021] The following will, with reference to the drawings, detail the technical solutions provided by the embodiments of the present application.

[0022] Embodiment 1

[0023] Embodiment 1 of the present specification provides a device for replacing the concrete lattice columns of the roof flower rack with ALC boards. Please refer to Figure 1 As shown, it includes a first ALC board 1 and a second ALC board 2. 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; first pipe clamps 5 are respectively inserted at the top and bottom of the first ALC board 1, 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 clamps, and adhesives are respectively provided at the top and bottom of the first ALC board; second pipe clamps 6 are respectively inserted at the top and bottom of the second ALC board 2, 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 clamps, and adhesives are respectively provided at the top and bottom of the second ALC board.

[0024] Preferably, the first pipe clamp (the first and second pipe clamps have the same structure and are collectively referred to as pipe clamps herein) has a T-shaped structure and includes a bottom plate 51 and a column 52 provided on the bottom. The adhesive includes mortar.

[0025] Preferably, refer to Figure 2 As shown, a cross beam 53 is provided at the top of the column 52, and slots capable of inserting the cross beam are respectively provided at the top and bottom of the first ALC board. The setting of the cross beam can improve the stability of the board and prevent the board from rotating during the installation process.

[0026] Embodiment 2

[0027] Embodiment 2 of this specification provides a construction method using ALC boards to replace the concrete lattice columns of the roof flower rack, including:

[0028] S1. Drawing and positioning: Draw positioning lines to determine the installation positions of the ALC boards;

[0029] It should be noted that before installation, first clean the base layer, position the installation positions of the ALC boards and draw positioning lines, and then use a twist drill to drill holes at the pipe clamp insertion positions 80 mm from the board end. The drawing and positioning method can use the traditional drawing method. For example, use a laser level to position the ALC boards on the floor slab / concrete beam, and use a 14 mm twist drill to drill holes at the pipe clamp insertion positions 80 mm from the board end.

[0030] S2. Installation of the first ALC board: After determining that the moisture content of the first ALC board is within the specified threshold, lift the first ALC board, insert the first pipe clamps at the bottom and top of the first ALC board respectively, install the first ALC board to the corresponding positioning lines, and connect the two first pipe clamps to the steel beam and the floor slab respectively;

[0031] In a possible implementation, the pipe clamp is made of Q235B galvanized material with a minimum thickness of 1.5 mm. Before installation, first clean the base layer. During the construction of the pipe clamp, insert the pipe clamp at a position 80 mm from one side of the board end. During installation, first insert the pipe clamp along the thickness direction of the ALC board into the corresponding hole positions, and then use an upright board machine to stand up the strip board and install it to the positioning lines.

[0032] Further, check the specifications of the connectors and tools before the start of installation; during the installation process, first position and then install to ensure that there is no interference with the steel bars inside the board; after installation, check whether there are cracks around the installation positions of the boards and whether the connectors are loose, etc. The moisture content of the ALC board should be detected before standing up the board and should be controlled within 30%.

[0033] When hoisting, fix one end of the sling to the winch hook, and let the other end go around the wall panel (the panel refers to the ALC panel) for one week, then hoist the wall panel by the winch. Before installing the wall panel, clean the working surface and the panel, and there shall be no dust, oil stains or other sundries. Apply the special ALC adhesive fully in the male and female grooves on the side of the already installed wall panel, and the mortar in the groove shall not be less than half of the groove depth. If the mortar drops to the ground, it is strictly prohibited to use it again. The adhesive caulking is generally not less than 4 - 5 mm from the panel surface to make the joint between the wall panels more flat and firm. The pipe clamp is fixed to the structure by shooting nails, and 2 shooting nails are used for a single pipe clamp.

[0034] S3. Installation of the second ALC panel: Apply the adhesive on the fitting side of the first ALC panel. After determining that the moisture content of the second ALC panel is within the specified threshold, hoist the second ALC panel, insert the second pipe clamps at the bottom and top of the second ALC panel respectively, fit the second ALC panel with the first ALC panel to extrude the mortar, and the width of the vertical joint after extrusion shall be within the threshold, then connect the two second pipe clamps to the steel beam and the floor slab respectively;

[0035] In a possible implementation, the installation method is basically the same as that of the first ALC panel. The difference is that a crowbar is used as an aid to push the second ALC panel towards the already installed panel (the first ALC panel); the adhesive extrudes from the panel joint, ensuring that the width of the vertical joint after extrusion is about 5 mm and the upper and lower vertical joint widths are the same to ensure the bonding force between the wall panels. Mortar should be scraped and plastered on both sides of the end of the already installed panel. Half of the groove of the panel to be installed (the second ALC panel) is filled with mortar, and mortar is not scraped and plastered on both sides of the end of the panel to be installed to prevent it from falling off during handling, standing the panel and installation; for the panels with a lower height, the manual pushing method can be adopted, and for the large panels, methods such as crowbars and straps can be used to ensure uniform stress; after the mortar extrusion is completed, the panel should be fixed in time and the mortar extrusion effect should be checked. If there are voids, they should be repaired immediately.

[0036] It should be noted that the thickness of the mortar scraping and plastering during the mortar extrusion operation should be strictly guaranteed to ensure the density of the bonding mortar; the panels shall not be freely fitted into place, and a crowbar or a strap (for larger panels) shall be used to make the two panels close to each other to ensure uniform mortar extrusion; to ensure compatibility and the quality of the wall panel joints, the special ALC adhesive mortar shall be used for the panel joint adhesive mortar, and it shall not be mixed or replaced.

[0037] S4. Adhesive filling: Use auxiliary equipment to make gaps exist between the top and bottom of the installed first ALC panel and the second ALC panel and the steel beam and the floor slab respectively, and fill the adhesive in the gaps;

[0038] In a possible implementation, clean the working surface at the bottom of the ALC board. Place 2 triangular wooden wedges or rubber pads on each side of the wall board as temporary fixation for the wall board. The gaps at the top and bottom of the board are both 1 - 2 cm. When erecting the board, it is advisable to use a winch or a truck crane to improve the installation efficiency and ensure the safety of wall board installation. Push and fill the adhesive with a narrow putty knife until it overflows from the other side of the bottom board seam; use a putty knife to smooth both sides. The bottom board seam after filling should be full without omission to prevent cracking caused by board settlement; after the mortar reaches the required strength, remove the wooden wedges and repair the positions where the wooden wedges were filled with a homogeneous special adhesive. If rubber pads are used, the work can be completed in one go.

[0039] It should be noted that before installation, the plates and processes shall be rechecked according to the construction drawings; during the installation process, the same point on the plate shall be positioned twice to ensure the verticality of the plate, and check whether the amount of plastering is sufficient; after installation, check whether the caulking and bedding mortar are full and meet the process requirements.

[0040] After the adhesive reaches the required hardness, the construction is completed.

[0041] It should be noted that when the board length ≤ 4m, the bottom of the strip board does not need to be fixed; when the board length > 4m, a pipe clamp is set below. The pipe clamp is made of Q235B galvanized material with a minimum thickness of 1.2 mm.

[0042] It also should be noted that the term "comprises", "comprising", or any other variation thereof is intended to cover a non - exclusive inclusion, such that a process, method, commodity, or device that comprises a series of elements includes not only those elements but also other elements not expressly listed, or elements that are inherent to such process, method, commodity, or device. Without further limitation, an element limited by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, commodity, or device that comprises the said element.

[0043] The above - mentioned are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
