In the block laying, a wet laying method or a dry laying method can be employed.
The wet bricking method comprises the following specific steps: before building, the common building blocks and the self-locking hollow building blocks are wetted, impurities on the surfaces of the building blocks are washed away, one building block is built to correct one building block from a corner or a positioning building block at the beginning of each building block, and mortar is filled in transverse and vertical seams. The exposed end of the self-locking hollow block is knocked off the convex rib on the side surface by a masonry knife and is plugged by a plugging block or concrete, and the groove on the upper part of the self-locking hollow block is filled and leveled by mortar or fine stone concrete in the same length of the plugging block. When the wall body is built to the last skin of the top surface, the waterproof ribs at the top of the self-locking hollow building blocks are knocked off, construction is carried out at the joint of the self-locking hollow building blocks and the upper structure by adopting a wedge-shaped building method, and the self-locking hollow building blocks are not matched with modules and are filled with fine aggregate concrete.
The case of using the wet masonry method requires attention is:
(1) when the wall body has no door and window openings, reinforced concrete belts are arranged in grooves at the tops of the self-locking hollow blocks every 4-6 sheets of the self-locking hollow blocks; when the wall body is provided with a door and window opening, a reinforced concrete belt is arranged on the top groove of the self-locking hollow block below the opening and the self-locking hollow block on the lintel at the top of the opening.
(2) The interface of the self-locking hollow block and the beam, the column or the concrete wall is provided with a thin steel wire net before painting, and then is plastered by waterproof mortar, so as to achieve the purposes of reinforcing the wall and preventing cracking and falling.
The concrete method of the dry-masonry method is as follows: during construction, a wall body is built by common building blocks and self-locking hollow building blocks, then the formed wall body is watered and moistened, mortar is filled at the transverse and vertical joints or pressure is applied during wall plastering, the mortar is squeezed into mortar joints, and the plumpness of the mortar joints is required to reach more than 80%. Two tie bars are arranged in the height positions of every two self-locking hollow building blocks, and the tie bars extend into the wall body by not less than 1000 mm.
The dry-laying method needs to be carefully adopted in the following cases:
(1) and a steel wire mesh is arranged at the joint of the self-locking hollow building block and the beam, the column or the concrete wall.
(2) A15-20 mm gap is reserved between the top skin self-locking hollow building block and the beam bottom or the slab bottom of the upper floor, similarly, the top skin is used for knocking off the waterproof ribs at the top of the self-locking hollow building block, and then a flexible connecting material meeting the deformation requirement is filled in the gap.
Construction conditions in winter: and (3) entering winter construction when the average temperature of the continuous 5 balances is lower than 5 ℃ or the lowest temperature of the day is lower than 0 ℃, and adopting winter construction measures. Before building the small-size building blocks used in winter construction, frozen objects such as frost and the like should be removed. The thickness of the construction mortar is increased to over 88mm in winter, the masonry mortar is mixed by common Portland cement, frozen blocks with the diameter of more than 10mm cannot be contained in the mortar, and the use temperature of the mortar is not lower than 5 ℃.
Construction conditions in rainy season: when the masonry is carried out in rainy season, rain-proof measures are needed, the mortar is prevented from being washed by rainwater, and the consistency of the mortar is reduced to below 50 mm; the building height is less than or equal to 1.2m every day, the surface of the wall body is covered during work collection, the verticality of the wall body is checked after heavy rain, and the building blocks which are sprayed with water are dried and used after being checked by professionals.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
