The designed compressive strength values are as follows:
1. the strength grade of the building block is MU5, the strength grade of the mortar is Mb5 → the design value of the compression strength of the masonry is 1.31 MPa;
2. the strength grade of the building block is MU3.5, the strength grade of the mortar is Mb5 → the designed value of the compressive strength of the building block is 0.95 MPa.
3. The mortar strength M5, the design value of axial tensile strength, bending tensile strength and shear strength 0.08 MPa.
Elastic modulus of the masonry: 1500f (non-grouted concrete block masonry, when the mortar strength is M5), wherein f is the designed compressive strength value of the masonry.
Allowable height-thickness ratio of masonry wall: when the mortar strength is M5 or Mb5, the height-thickness ratio of the masonry wall does not exceed 24. When the thickness of the non-bearing wall is 90-240 mm, the height-thickness ratio can be corrected by adopting a correction coefficient of 1.2-1.5. For example, when the thickness is 240mm, the correction coefficient is 1.2; the correction factor was 1.28 for a thickness of 200mm and 1.5 for a thickness of 90 mm.
The steel strip 4 is Q345B, and the design value f of tensile strength, compression strength and bending strength is 305N/mm2Design value of shear strength fv 175N/mm2Modulus of elasticity 2.0x105N/mm2。
In the embodiment, the center distance between the steel belts 4 is 800mm, and the steel belts 4 are arranged on two sides of the wall. The width of the steel strip 4 is 80mm, the thickness is 3.5mm, and the net section coefficient is 0.85. The tensile design value of the steel strip 4 is 72.5kN, and the shear design value is 44 kN; the deformation of the steel strip 4 is shown in Table 2.

Wherein the maximum elongation of the steel strip 4 in elastic deformation is 3.8% L, and L is the length of the steel strip 4.
Of course, the calculated requirement is satisfied, the center distance of the steel strip 4 can be less than 800 mm; similarly, the width of the steel strip 4 can be less than 80mm according to calculation requirements, and single-sided steel strip installation is also allowed.
8.8-grade split bolts are selected as the wall-penetrating bolts 7 of the steel belt 4. Tensile strength design value of split bolt 400N/mm2Shear strength design value 320N/mm2. The center distance of the through-wall bolts 7 on the same steel strip 4 is 600 mm.
Wherein, the basic design parameters of the anchor bolt are shown in a table 1.

Designed anchor bolt tension value Rd (kN) and standard concrete strength value of 30N/mm2。
The additional loads include: thin stonePlate material 33.9kg/m213.0kg/m rock wool board2The self weight of the steel strip 4 is 2.2 kg/m; masonry at 1000kg/m3And (4) calculating.
Beam waiting generation: section 800x200mm, calculated load per extension meter: the additional load is 0.397kN/m, the self weight of the wall body is 1.6kN/m, the total is 1.997kN/m, and the total is calculated according to 2.0 kN/m.
The system's shock resistance is verified below.
Calculating the bearing capacity of the wall body:
vertical: the height of the filler wall 61 is calculated according to 3000mm (if the height exceeds 3000mm, a reinforced concrete strip needs to be arranged), the steel strips 4 inside and outside the wall body are connected by using split bolts, and the steel strips 4 only bear the additional load in the vertical direction, namely 0.397x3 is 1.191 kN.
Tensile strength (min22.4kN) and shear strength (min12.36kN) of the split bolt; the steel belt 4 is tensile (72.5kN) and far larger than the additional load, so that the requirement is met.
Level: calculated by the bottom shear method, FEK＝a1Geq calculation of a1For horizontal seismic influence coefficients: small 0.16, medium 0.45 and large 0.90. Horizontal seismic force (units of computation per linear meter): small vibration of 0.32kN, medium vibration of 0.90N and large vibration of 1.8 kN.
The sectional area of the wall body is 0.2m x0.8 m-0.16 square meter, the design value of the shear strength is 0.06MPa, and the self shear-resistant bearing capacity of the wall body is 0.16x0.06x 1000-9.6 kN. If the wall height is 3000mm, the small earthquake shear force Vmax is 0.32x3 which is 0.96kN, the medium earthquake Vmax is 0.9x3 which is 2.7kN, the large earthquake Vmax is 1.8x3 which is 5.4kN, and the small earthquake shear force Vmax is less than 9.6kN, namely, the horizontal earthquake shear force can be met under the condition that the steel strip 4 is not added, the wall shear force is met, namely, the masonry can not crack along the through seam, namely, the wall deformation meets the requirement, the steel strip pendant and the wall are clamped into a whole due to the split bolts, and the outer facing deformation meets the requirement.
(II) calculating the horizontal bearing capacity of the equivalent beam:
The deformation is calculated according to the elastic theory, when 44kN is adopted, the deformation amount is 1500x3.8 percent to 57mm, the small vibration 57x0.095/44 to 0.123mm, the medium vibration 0.337mm and the large vibration 0.69 mm.
The maximum allowable deformation value is L/250, namely 12mm according to the specification of the curtain wall. Wind load is calculated according to 0.65 x1.1x0.7-0.5 kN/square meter (negative wind pressure), the wind suction force is 0.5 x0.8x1.5-0.6 kN, the elongation of the steel strip 4 is 0.78mm (the local wind pressure change part needs to be strengthened), and the deformation of the steel strip 4 meets the requirement according to the elongation.
Therefore, the contribution of the combination of the steel belt 4 and the wall body to the rigidity and the bearing capacity is not 1+1, the rigidity and the bearing capacity after the combination are greatly improved, and the part for improving the bearing capacity after the combination can be used as safe reserve.
If the wall thickness does not meet the anti-seismic requirement through calculation, the steel strip 4 can be changed into profile steel and implemented according to the specifications of dry-hanging stone curtain walls.

the middle part of the vertical plate of the lifting and supporting piece 2 is connected with a wall through bolt 7, and the steel belt 4 and the lifting and supporting piece 2 are fixed on the wall body together by the wall through bolt 7. The free end of the vertical plate of the lifting and supporting piece 2 is connected with the steel belt 4 through a bolt 5, and the bolt 5 can be a carriage bolt.
An insulating layer 8 is arranged between the wall body and the buckling groove plate 3, and the buckling groove plate 3 can be a stone plate, a porcelain plate, a calcium silicate plate, a cement fiber pressure plate and the like.
The construction method of the building frame infilled wall combined installation system comprises the following steps:
(1) as shown in fig. 1 and 2, the wall bolt 7 is embedded in the wall body in advance;
(2) fixing the steel belt 4 on the infilled wall body 61, the upper beam 62 and the lower beam 63 through wall bolts 7;
(3) and installing a double-hook hanger body 1: the double-hook hanger body 1 is grabbed on the buckling groove plate 3, and glue is injected to reinforce the contact part; the buckling groove plate 3 is manufactured according to the design specification;
(4) the connector of the lifting and supporting piece 2 is arranged in the bracket of the double-hook hanging piece body 1;
(5) the heat-insulating layer 8 is bonded with the back surface of the buckling groove plate 3 in a cold-pressing and static-maintaining way;
(6) as shown in fig. 16 and 17, the lifting member 2 is fixed to the wall.
The heat-insulating layer and the buckling groove plate can be fixed on the steel belt and the wall together through the double-hook hanging piece body and the lifting piece, the structure is simple, independent hanging can be realized, and the installation is very convenient; the buckling groove plate is firmly grasped by the double-hook hanger body, and the double-hook hanger body is firmly fixed on the wall body through the lifting and supporting piece and the steel belt, so that the formed assembly body has stable structure, firmness, durability and strong shock resistance.
The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
