5、tweight wall materials have been developed, as wall material multi-storey and high-rise frame structure, use them to replace the traditional clay brick wall materials has become a inevitable result of history.The clay ceramsite concrete hollow block, referred to as the clay block, is made from clay
6、ceramsite calcined at high temperature after extrusion into the Department of orthopedics, with cement as cementing material mixed with ceramic sand according to a certain proportion by pressing the blind hole type hollow or solid block, characterized by light weight, good noise and large amount use
7、d in multi-storey and high-rise buildings the frame structure, not only reduces the structural load, reduce the section size of the wall, column, beam, and the relative increase in the use of the building space, the room layout is more flexible.2 featuresMake full use of masonry mortar embedded in t
8、he block hole, form a bonding pin key, block block sliding, forming a common force body, to ensure the overall performance of the wall.Developed a solid block, for windows and doors and walls, staggered joint, improved the laying of traditional methods, in the interface of masonry and concrete and t
9、he opening slot at the wall and the wall to eliminate the interfacial crack crack in the steel wire net.Compared with clay brick masonry, it has the advantages of fast masonry speed, convenient operation and small labor intensity. Its walls are light, and its properties conform to the needs of China
10、s wall reform.3 scope of applicationThe utility model is suitable for multi-storey and high-rise frame structures, indoor partition walls, partition walls and retaining walls.4 process principle4.1 according to the concrete hollow block group method, the blind hole of the block is facing up, and the
11、 back wall is built on the wall. The mortar is embedded in the hole of the block, and the 8-10mm forms a bonding pin, which blocks the block to slide and form a common force body.4.2 sets of wall Rachel reinforced and reinforced concrete column wall, reliable connection, when the wall length more th
12、an 3m in the wall of constructional column, deformation block wall and concrete wall column contact interface and the direction of the length of the wall, to prevent masonry structural cracks.4.3, in the block wall and the concrete structure contact interface, slotted openings and holes around the e
13、stablishment of steel wire mesh, to prevent wall paint layer turtle cracks.4.4 take the necessary structural measures, such as adding a long steel structural column, the amount of configuration to increase the overall performance of the wall temperature shrinkage stress.5 process flow and operation
14、points5.1 processConstruction preparation, cleaning at the grassroots level, dividing the bullet line, setting up the leather number, setting the wall, pulling the reinforcing bar, laying out the first brick, laying out the wall, laying the bricks, and finishing the node before the plastering.5.2 op
15、eration points:5.2.1 clean the slurry, loose concrete blocks, sundries and so on before the masonry, so as to clean the base surface.The position of the sideline and pop 5.2.2 masonry wall.5.2.3 vertical count rod: masonry level, seam thickness is controlled at 8mm to 12mm.5.2.4 set up wall reinforc
16、ing bars on the concrete wall column according to the location of the wall, the number of leather bars and the spacing of the tie bars.5.2.5 according to the position of a wall line and the line of position for the first door skin brick loft.5.2.6 masonry method according to the improved method of g
17、roup construction, horizontal seam ash thickness of about 20mm, in order to ensure that there are 8-10mm embedded block holes, forming a bonding pin key.5.2.7 verticality control of the wall: using line drop method to control.5.2.8 mortar plumpness: the horizontal joint is constructed by extrusion m
18、ethod, and the end joint is filled with grout.5.3 technical measuresThe interface crack of ceramsite masonry and concrete structure and the cracking of surface plastering layer are the common quality defects of ceramsite masonry wall. The root of this problem lies in the lack of improvement of tradi
19、tional masonry technology and the lack of targeted technical measures.In the construction of ceramsite masonry, the following technical measures must be taken in accordance with its characteristics:5.3.1 first floor wall root 640mm high within the scope of the use of solid masonry blocks, block hole
20、 to prevent moisture absorption of water, causing the wall mildew,The wall and the wall group method as shown in figure 1.5.3.2 blocks for wrong seam are made of solid blocks.In the 5.3.3 wall, the blocks at the level of the pre embedded pipeline are made of masonry blocks with concave troughs.5.3.4
21、 Rachel reinforced wall set: pitch height direction is 6 500mm, usually along the wall layout, the lap length is 45d, a reliable connection with the main structure, Rachel reinforced block arranged in the blind hole, and should be placed in the steel covered with cement mortar, Rachel reinforced mas
22、onry with solid upper block, wall corner added 1 with 6 corner construction steel, as shown in figure 2.5.3.5 the length of the wall is more than 3m, according to 2500mm set 190mm * 190 (120) mm, with 4 Phi 10, phi 6 250 cast-in-place reinforced concrete structural column.5.3.6 doors and windows mus
23、t be lined with solid blocks on both sides.5.3.7 masonry wall and the floor at the junction of the use of special solid block, was fish scale oblique masonry tight, and its construction time should be completed in the lower masonry after a week, the special block shown in figure 3.5.3.8 treatment of
24、 external dry hanging stone curtain wall or glass embedded parts as shown in figure 4.5.3.9 wall corner and T-shaped wall should be built simultaneously, temporary office should be built into discontinuous oblique oblique Cha Cha, horizontal projection length should not be less than the height of th
