The important control points in the construction process of rural houses
1. Rural residential foundation
(1) The foundation of the design map of rural houses must be excavated to the old soil layer, the soil quality should be uniform, and the depth of the old soil should not be less than 20cm.
(2) The burial depth of the rural house design plans (calculated from the lowest value of the outdoor floor after completion) should not be less than the thickness of the local permafrost, and should not be less than 50cm. If necessary, there should be design. The foundation trench (pit) backfill soil should be layered and compacted.
(3) After the basic design of the rural house plans is controlled to the bearing layer, whether there are voids or weak layers under the foundations of the steel (coarse) detection is applied, and if so, it shall be removed and dug to the old land.
(4) After the floor of the design plan of the rural house meets the requirements, the foundation shall be immediately constructed to avoid rain soaking and exposure. If soaking occurs, the soaked and softened foundation soil shall be removed before the foundation construction; after the foundation construction is completed, Backfill immediately to avoid water soaking and disturb the foundation.
 
2, rural residential rubble base
(1) Design of small rural villas. Masonry foundation masonry: The rubble foundation should be layered and masonry (this is also the case between the first layer of rubble and soil). It should be face down and up and down. If the foundation is a ladder, it should be erected from the lowest point;
(2) The design of the small rural villa should leave gaps between the rubble, and it should be done with masonry mortar. Instead of dry rubbing a layer of rubble, and then laying a layer of mortar, then the construction method of flushing the joints with water to avoid cement Lost by water.
(3) The design of rural villas should be made of masonry stone, stones with better stones should be used, and weathered stones should not be used.
  
3, rural cottage design residential brickwork project
(1) The strength of the selected brick must meet the requirements, and it should be sent to the inspection department for inspection before it can be used.
(2) The load-bearing wall shall be a 240-mm solid brick wall (a brick wall), and the empty-bucket wall shall not be used as a load-bearing wall.
(3) In order to ensure the quality of the masonry, it is forbidden to dry the bricks on the wall, and a unified assembly method shall be adopted. The fullness of the horizontal mortar joints of the brickwork shall not be less than 80% (ie, the contact surface between the bricks and the mortar); The mortar must be full and the thickness of the seam should be controlled between 8-12mm.
(4) In the design of rural villas at the corners or intersections of brickwork, the masonry shall be constructed at the same time. When the construction (masonry) cannot be performed at the same time, the slanting shall be kept (stepping), and the division shall not be divided into two separate parts. The construction (except for the structural column here) has no reliable connection between the vertical and horizontal walls, resulting in cracking or even collapse of the wall. (5) In the corners or intersections of the wall with or without structural columns, wall bars (not less than 2 Ф 6 rebars) shall be provided along the height of the wall every 500 mm, and the length of the pull bars shall be deeper than the walls. Less than 1 meter.
(6) It is forbidden to open a horizontal groove on the masonry brickwork that has been completed, or to make holes in the wall.
(7) Masonry mortar shall be constructed according to the specified proportions, mechanical stirring shall be adopted, water shall not be added arbitrarily during use, and must be used up within a certain period of time (before the initial coagulation of the mortar loses its fluidity), and shall not exceed 2 hours. Instead of lime cream, stone powder is strictly prohibited instead of sand.
(8) The thickness of the lintel of doors and windows for rural villa design drawings must meet the requirements. The length of the shelving on both sides of the lintel must not be less than 250 mm, and the bottom of the lintel should be filled with pulp. For example, the reinforced beam ribs and the diameter of the bottom reinforcement Should be Ф6-Ф8mm, both ends of which extend into the wall not less than 240mm. Both ends of the steel bar must be hooked. There must be no less than three steel bars and the strength of the cement mortar is not less than M5.
(9) Monolithic walls that are not connected to other masonry at both ends, (such as structural columns at both ends, but the structural column has not yet been poured). The height of the masonry should not exceed one step scaffolding; if it must be exceeded, temporary stabilization should be adopted. Measures to prevent the masonry from collapsing under the influence of external forces (such as strong winds).
(10) The dimensions of the temporary openings for the construction of rural cottages should not be more than 900 mm and the height should not be more than 1.8 meters. The lintels should be installed here. When the caverns are made up, they should be bitten with both sides.
(11) The external walls of the scaffolding should be plugged so as not to cause water leakage on the external wall.
