[0029] (e) When preparing adhesives, proceed according to the professional instructions and use them within the specified time.
[0030] (f) When injecting the rebar embedding glue, the air in the hole should not be blocked from being discharged. The amount of glue injected should be 2 / 3 of the hole depth, and a small amount of glue should be allowed to overflow from the hole after the rebar is implanted. After the rebar embedding glue is injected, the rebar should be immediately inserted in a single direction until the bottom of the hole. It is strictly forbidden to embed the rebar by dipping the rebar in glue and then directly inserting it into the hole.
[0031] (g) After the steel bars are implanted, the cementing glue should be allowed to cure for 24 hours. During the curing period, the steel bars must not be disturbed.
[0032] (h) After the steel bars have been cured, on-site physical testing (pull-out test) shall be carried out promptly in accordance with the requirements of the specifications.
[0033] (i) Before carrying out large-scale rebar planting construction, sample rebar planting should be carried out on site first, and then random sampling should be carried out on site to conduct pull-out resistance tests on the manufacturer's anchoring glue and anchoring steel bars. Only after passing the test can large-scale rebar planting be carried out.
[0034] (4) Masonry blocks. The construction requirements for masonry blocks include the following: (a) On the day of masonry, the masonry surface of the blocks should be sprayed with water to moisten them. The amount of water sprayed should be such that the blocks are moistened to a depth of 3 to 5 mm.
[0035] (b) Before the infill wall is constructed, a 200mm high step with the same width as the wall shall be cast with C20 fine stone concrete at the corresponding position of all infill walls around the water room; a 200mm high C20 concrete base strip with the same width as the upper wall shall be added at the base of the balcony, terrace, bathroom and kitchen (including pipe well). It is strictly forbidden to use wire to penetrate the mold to create a step.
[0036] (c) Block arrangement Facade brick arrangement: Calculate the number of layers according to the net height of the wall, the height of the bricks and the thickness of the mortar joints, select the appropriate combined brick arrangement method, and determine the number of brick layers. Attention should be paid to the height and position of the door opening lintel and ring beam. When building the exterior wall, the facade brick arrangement should also consider the height and position of the window opening.
[0037] Plane block arrangement: Before laying, the blocks should be arranged in the plane position. Place the aerated concrete blocks along the axis direction between the two frame columns, adjust the gap (pay attention to the treatment of the door opening and the structural column), and when they are arranged at both ends of the wall, if the whole block cannot be arranged, the aerated concrete blocks can be cut and sawed, but the length cannot be less than 1 / 3 of the whole block length. When aerated concrete blocks are laid with dry mortar, the width of the horizontal and vertical mortar joints are both 10~15mm.
[0038] (d) Block cutting should be done with portable tools or small cutters. It is strictly forbidden to chop with axes, trowels, etc. Mortar should be used with the block.
[0039] (e) The masonry is laid by first spreading mortar and then pressing bricks for correction. The mortar is spread with a mortar shovel according to the mortar joint thickness requirements. The mortar spreading length shall not exceed 1500mm, and the amount of mortar used for two masonry blocks is appropriate. Then the masonry blocks are aligned with the masonry line and placed steadily, squeezed, and hammered with a wooden hammer until they are tightly combined with the mortar. It is required to lay and correct one block at a time during the masonry process to minimize the number of reworks.
[0040] (f) The mortar of horizontal joints should be full. The fullness of mortar should not be less than 80%. The joints should be horizontal and vertical. The mortar is full. Vertical joints should be filled with internal and external plywood. No transparent joints, blind joints or false joints should appear. The fullness of mortar of horizontal joints should not be less than 80%.
[0041] (g) Each layer of bricks should be checked for leveling, so that the horizontal joints are uniform, straight and smooth. It is advisable to use an external hand hanging line to ensure the flatness of both sides of the brick wall, thereby controlling the thickness of the plaster. The mortar joints should be pointed as the masonry is laid. After each layer of bricks is laid and corrected in place, the vertical joints are filled with mortar, and then the mortar joints are tightened to a depth of 2 to 3 mm.
[0042] (h) The upper blocks can be laid only after the mortar of the horizontal joints of the first layer of blocks has initially set. The daily laying height should be controlled within 1.8m. A gap (18cm~20cm) should be reserved between the top surface of the masonry wall and the bottom surface of the reinforced concrete beam (slab). The gap should be filled 15 days after the wall is completed. The gap is laid with inclined bricks, and the middle and both sides are filled with prefabricated triangular blocks.
[0043] (i) The masonry should be laid sequentially starting from the corners or intersection walls. The inner and outer walls should be laid simultaneously. The vertical and horizontal walls should be laid crosswise. The joints should be staggered up and down during the masonry work. The infill walls should not have continuous joints. The overlap length should not be less than 1 / 3 of the length of the masonry block.

[0045] (k) The corners and joints of the block wall should be built at the same time. It is strictly forbidden to build the inner and outer walls separately without reliable measures. Temporary breaks that cannot be built at the same time and must be left should be built into inclined joints, and the horizontal projection length of the inclined joints shall not be less than 2 / 3 of the height. When repairing temporary breaks, the mortar and debris at the joints should be cleaned, watered and moistened, and filled with mortar to keep the mortar joints straight.
[0046] (5) Casting of ring beams, lintels and structural columns. The requirements for setting structural columns include the following: 1) In addition to the structural columns clearly marked in the structural drawings, if the infill wall meets any of the following conditions, structural columns must be set as required: a. When the size of door and window openings is ≥2m, structural columns must be set on both sides; b. When the wall length is ≥5m or twice the floor height, structural columns shall be set at intervals of 3m; c. When the end of the infill wall is unconstrained or has a concrete wall (column), a structural column is set at the end; d. Structural columns should be set at the intersections of different walls; e. Structural columns are installed at the corners of brick elevator shaft.
[0047] like Figure 2 As shown, it shows a schematic diagram of the cross-section structure of the structural column. In the figure, the wall thickness is 190 (90) × 200, the reinforcement is 4C10, and the stirrups are C6@200.
[0048] 2) Construction requirements for structural columns include the following: a. The masonry at the structural column position is built in a tooth-shaped form. The tooth-shaped joint is left from the root according to the principle of retreating first and advancing later. The advance and retreat size is 60mm, and the height of the aerated concrete block is staggered at intervals of one layer.
[0049] b. The formwork of the structural column is made of 15mm thick plywood, the secondary back ribs are made of wooden squares, and are placed vertically on the ground; the main ribs are made of wooden squares, and the horizontal spacing is 500mm. A row of A14 tension screws is set in the middle of the column.
[0050] c. The structural column reinforcement should be anchored into the upper and lower beams and slabs at each La.
[0051] d. The main reinforcement of the structural column is overlapped by binding, the overlap length is 50d, and the thickness of the steel bar protective layer is 20mm.
[0052] e. The concrete of the structural column can be poured in sections, each time pouring to the top of the ring beam or window sill.
[0053] f. When the formwork of the structural column reaches 300mm above the bottom of the beam, use the formwork to set up a 45° angle concrete pouring feed port. After the concrete is poured and reaches initial setting, the concrete in this triangular part is chiseled off. Figure 3 As shown in the figure, it shows the structural diagram of the structural column in the normal position; Figure 4 As shown, it shows the structural schematic diagram of the structural columns at the door and window openings.
[0054] 3) The construction process of ring beam and lintel includes the following: When there is no beam or slab at the top of the infill wall, a top ring beam is set at the top of the wall, and the longitudinal reinforcement is anchored into the concrete column and wall La. When the wall height is greater than 4m, a full-length concrete structural belt should be added every 2m (or above and below the window, above the door). Where there is no beam at the top of the door and window openings in the infill wall, a reinforced concrete lintel is set. If the opening is close to the concrete column or wall or the length of the infill wall beside the concrete column or wall is less than the support length of the lintel, the longitudinal reinforcement of the lintel should be reserved in the column first, and then the lintel should be cast. When the distance from the top of the door and window opening to the bottom of the floor beam is ≤h (lintel height) +100mm and it is impossible to set up a separate lintel, the top lintel of the opening and the floor beam are cast at the same time. The lintel is 250mm deep in the width of the opening. The ring beam can also serve as a lintel, but the position size and reinforcement of the lintel should meet the requirements of the lintel. When there is a door opening in the wall, the ring beam also serves as a lintel. The connected wall ring beams are set at the same elevation. The exterior wall needs to be equipped with window sill beams, with the ends extending 250mm on both sides. When the elevator is surrounded by infill walls, ring beams should be set at intervals along the height according to the elevator sample. The ring beam width is the same as the wall, the height is 00, the reinforcement is 2C12 above and below, and the stirrups are 6@150. If there is no sample reference during construction, ring beams should be set every half floor and not more than 2m. GZa: 200×200, 4C12, C6@200 are set at the corners of the elevator shaft infill wall.
[0055] 4) The construction requirements for ring beams and lintels are as follows: The reinforcement of ring beams and lintels are tied and overlapped, with an overlap length of 60d and a reinforcement protective layer thickness of 20mm. The formwork is made of 15mm thick multilayer board, and the secondary and main ribs are made of wood. The secondary ribs are arranged parallel to the beam direction; the bottom formwork of the lintel is in the form of 15mm thick multilayer board + wood + steel pipe formwork.
[0056] 5) Setting and construction of horizontal tie bars. A 2C6 horizontal tie bar is set every 500mm or two layers of bricks according to the wall height range. It is advisable to arrange it along the entire length of the wall (the length of penetration into the wall is not less than 600mm). The tie bar is connected to the main structure by planting bars. When connecting horizontal tie bars, tie overlap is adopted, and the overlap length is 400mm. When mortar masonry is adopted, the protective layer thickness of the horizontal tie bar is controlled at 20mm. The horizontal tie bar should be passed through the structural column and pass through the inner side of the main reinforcement of the structural column.
