DETAILED DESCRIPTION

[0021] A construction method for a masonry sandwich decorative wall is achieved by the following steps:

[0022] Step S1: Casting the structural column 1, embedding a plurality of main tie bars 2 arranged in the horizontal direction and evenly distributed vertically during the casting process, and welding and fixing the main tie bars 2 to the main vertical steel bars in the structural column 1;

[0023] Step S2: build an inner leaf wall 3 between two structural columns 1, and use aerated concrete blocks 4 as masonry units. During the masonry process, the two ends of the horizontally arranged seismic steel bars 5 are welded and fixed to the two main tie bars 2 that match the positions, and the horizontally arranged rectangular tie steel mesh 6 is welded and fixed to the two main tie bars 2 that match the positions, and then the seismic steel bars 5, the main tie bars 2 and the tie steel mesh 6 are built together between two adjacent layers of aerated concrete blocks 4 that match the positions; at this time, the tie steel mesh 6 exceeds the inner leaf wall 3; the size of the aerated concrete block 4 is 600mm*200mm*240mm; the tie steel mesh 6 is made of galvanized steel bars with a diameter of 4mm, and the overhanging length of the tie steel mesh 6 is 200mm;

[0024] When the masonry reaches the middle of each floor, a ring beam 7 is cast on the aerated concrete blocks 4, and a load-relief cantilever 8 is cast on the outside of the ring beam 7; the cantilever length of the load-relief cantilever 8 is 165mm and the cantilever thickness is 100mm;

[0025] Step S3: After the inner leaf wall 3 is built, a plaster layer is applied on the outer side of the inner leaf wall 3 for moisture-proof and leveling treatment; the plaster layer is a cement mortar mixed with 5% waterproof powder and a water-sand ratio of 1:2.5, and the thickness of the plaster layer is 20 mm;

[0026] Step S4: Install the insulation board 9 on the outer side of the plaster layer, fix the top of the insulation board 9 to the tie steel mesh 6 located on the upper side, and fix the bottom of the insulation board 9 to the tie steel mesh 6 located on the lower side, and use insulation expansion nails to fix the connection; the insulation board 9 is a Class A fireproof and hydrophobic rock wool insulation board 9 with a thickness of 80 mm and a width modulus of 500 mm;

[0027] Step S5: build an outer leaf wall 10 on the outside of the insulation board 9, using shale sintered bricks 11 as masonry units, and during the masonry process, build the tie steel mesh 6 that exceeds the inner leaf wall 3 between two adjacent layers of shale sintered bricks 11 that match the position; at this time, an air layer is left between the outer leaf wall 10 and the insulation board 9; the thickness of the air layer is 20 mm; the insulation layer and the air layer can block the transmission of sound waves, which can effectively reduce the transmission of sound waves by more than 95%;

[0028] Before building the outer leaf wall 10, a pull-out test is performed on the tie steel mesh 6; the size of the shale sintered brick 11 is 240mm*112mm*52mm;

[0029] When the masonry reaches the middle of each floor, shale fired bricks 11 are laid on the lower surface, upper surface and side surface of the unloading eaves 8, and the weight of the shale fired bricks 11 above the unloading eaves 8 is unloaded onto the unloading eaves 8;

[0030] Step S6: clean the outer leaf wall 10, and perform grouting and spraying of protective liquid on the outer leaf wall 10; the grouting adopts a flat seam form, and the thickness of the mortar seam recessed into the outer leaf wall 10 is 8mm~10mm; the depth of the grouting is consistent.

[0031] As attached Figure 1 As shown, in the steps S1 and S2, the lightning protection mesh is connected to the main body tie bars 2, the main body vertical steel bars, the seismic steel bars 5 and the tie steel mesh 6 to form a whole, forming the functions of the seismic resistance, lightning protection and shielding network of the entire building.

[0032] Especially when used in scientific research buildings, it can realize the electrostatic shielding function of precision laboratories against external interference signals and magnetic radiation, and play a protective role in the accuracy of precision experimental instruments, electrostatic short circuits of circuit boards, and the accuracy of test data.

[0033] As attached Figure 2 As shown, in step S5, the "three-in-one" masonry method is adopted when the outer leaf wall 10 is built, and the two layers of aerated concrete blocks 4 of the inner leaf wall 3 correspond to the eight layers of shale sintered bricks 11 of the outer leaf wall 10, ensuring that the tie steel mesh 6 is accurately pressed into the mortar joints with matching positions.

[0034] During the masonry, the problem of inconsistent elevations of the horizontal mortar joints of the inner leaf wall 3 and the outer leaf wall 10 is solved by adjusting the mortar joint width.

[0035] As attached Figure 3 As shown, in the step S5, when the shale sintered bricks 11 are built to the door and window openings or the awning position, the eaves of the structure eaves 12 are built in a vertical manner, and the shale sintered bricks 11 are cut into L-shape or C-shape. When laying, the cut shale sintered bricks 11 are hung on the eaves of the structure eaves 12; the eaves are completely covered; no secondary closing is required, and the outer leaf wall 10 is decorated in a seamless manner, which is beautiful and atmospheric.

[0036] In step S5, the outer leaf wall 10 is built by horizontal or vertical laying of shale sintered bricks 11; when vertical laying is adopted, a false joint matching the shape of the mortar joint is opened on a shale sintered brick 11 at the inner corner or outer corner, and is filled with grout.

[0037] A groove with a depth of 20 mm is cut on the surface layer of the shale fired brick 11 as a false seam, and the outer leaf wall 10 after treatment is neat and beautiful.

[0038] As attached Figure 4As shown, when the outer leaf wall 10 is the outer leaf wall 10 of the scientific research building, a number of gas cylinder rooms close to the ground are built on the outer side of the outer leaf wall 10, and a triangular wall 13 arranged vertically is built on one side of the top of each gas cylinder room, and a triangular pyramid wall 14 arranged vertically is built on the other side, and the top of the triangular wall 13 and the top of the triangular pyramid wall 14 are jointly built with a U-shaped channel 15 that is close to the outer leaf wall 10 and opens to the outside; a pipe hole 17 is opened on the upper surface of the gas cylinder room.

[0039] When the triangular pyramid wall 14 is built, ordinary bricks are laid inside the triangular pyramid wall 14, and 240mm sintered shale bricks 11 are laid outside the ordinary bricks, which are integrated with the outer leaf wall 10; the oblique part of the triangular pyramid wall 14 is gradually retreated upwards and built to the bottom of the U-shaped channel 15;

[0040] The gas cylinder room is used to place inflammable and explosive gas cylinders. The pipelines of the inflammable and explosive gas cylinders are laid into each laboratory through the pipeline hole 17 and the U-shaped channel 15. When the inflammable and explosive gas cylinder explodes, the explosion shock wave is directed toward the outside of the scientific research building, ensuring the safety of the researchers in the laboratory.

[0041] During the specific implementation process, when the inner leaf wall 3 is built, the pre-buried main tie bars 2 are first straightened, and then the masonry position line of the structural base is determined according to the sizes of the aerated concrete blocks 4 and the shale sintered bricks 11; then the base is leveled with premixed mortar, and skin number rods are set on both sides of the inner leaf wall 3 to control the height direction positions of the masonry mortar joints, door and window openings, and eaves; then two layers of aerated concrete blocks 4 are built according to the positions of the skin number rods; then the galvanized steel mesh 6 is pressed into the mortar joints, and the galvanized steel mesh 6 is welded to the main tie bars 2 to form an integral structure.
