A house main structure construction method according to an embodiment of the present invention will be described below with reference to fig. 1 to 7.

The house main body structure building method comprises the following steps:

building a foundation;

pouring concrete into the first pouring space, and forming a constructional column and a frame column after the concrete is solidified;

building a frame body and a template above an integral structure formed by the wall body, the constructional column and the frame column, pouring concrete into a second pouring space formed by the frame body and the template, and forming a floor slab after solidification;

and constructing a roof on the floor slab, wherein the roof comprises a plurality of layers of stacked waterproof structures.

Referring to fig. 1 to 7, the foundation construction is a well-established technology, and after the foundation is constructed, the construction of the house main body can be started. When some rural villas are built, the house main body can be even directly built on the original foundation.

The building of the house body is first started from the ground construction. The structure on dampproofing ground is different from traditional ground structure, has increased multilayer waterproof construction on traditional ground structure, and in order to assist laying of multilayer waterproof construction, has add multilayer rigid structure as the support. The multilayer waterproof structure is separated by the multilayer rigid structure, and compared with the direct lamination mode of the waterproof structure, the waterproof and moistureproof capacity is improved, and direct damage to the waterproof structures of other layers when a certain layer of waterproof structure is broken is avoided.

After the ground construction is finished, the wall body can be built on the ground. A first pouring space is required to be reserved when the wall body is built, and the first pouring space is mainly used for forming a constructional column and a frame column after subsequent cement pouring. Usually, in order to ensure the stability of the wall body, a horse tooth rubbing is reserved at the joint of the wall body and the constructional column, so that the wall body can be effectively prevented from collapsing after the constructional column is poured subsequently. Country villas are most often built with two to three floors, with the frame posts as the primary support structure, often requiring one-shot forming. In addition, it should be noted that before the structural columns and the constructional columns are poured, reinforcing steel bars are arranged in the first pouring space to be poured and are bound, so as to achieve the purpose of reinforcing the structural strength of the constructional columns and the frame columns.

After the constructional columns and the frame columns are built, the floor slabs are poured on the integral structure formed by the wall bodies, the constructional columns and the frame columns. When the floor slab is poured, a frame body needs to be built firstly, a template is laid on the frame body, and a second pouring space is built through the template. A large amount of concrete can once only be directly poured in the second space of pouring, consequently, before pouring, need guarantee the roughness and the structural strength of template, avoid taking place to squint or collapse when concreting, lead to final floor deformation or need pour again. Similarly, the second pouring space also needs to be provided with reinforcing steel bars, so that the strength of the floor slab is improved, and the damage to a human body after the floor slab is broken can be reduced.

In actual engineering, when a multi-layer house main body is encountered, multiple times of floor slab pouring are needed, floor slabs of each layer are formed in sequence, and a roof is built on the floor slab at the topmost layer. In order to improve the water dispersing capacity of the roof, the roof of the country villa adopts a sloping roof, so that the water can be dispersed freely, the water dispersing capacity is better compared with a drainage water dispersing mode of a plane roof, and the risk that the drain hole is blocked by sundries such as leaves, dust and the like can be avoided. During the roofing was built, in order to improve waterproof ability, can increase the waterproof construction that the multilayer overlapped mutually on the roofing, then at the structural structure of laying the tile that sets up in waterproof, the improvement that like this can be very big last shaping roofing's waterproof ability, and adopt the mode that the waterproof construction was overlapped mutually to the multilayer, also can not be too much increase the structural thickness, the weight of roofing, also be convenient for be under construction.

According to the house main body structure building method provided by the embodiment of the invention, the rigid structure and the waterproof structure which are arranged in a staggered mode in a multilayer mode are arranged in the moisture-proof ground, so that the moisture-proof capacity of the ground can be effectively improved, and meanwhile, the structural strength of the ground can be kept. Through set up the waterproof construction that the multilayer was folded mutually in the roofing, can effectual improvement roofing waterproof ability. Compared with the traditional house main body, the house main body built according to the house main body structure building method provided by the embodiment of the invention has better waterproof and moistureproof capabilities on the premise that the main body structure is not greatly changed, and is suitable for popularization in vast rural areas.

At present, the construction of the ground is generally divided into two types, one is an overhead ground structure constructed by using prefabricated panels 220, and the other is a cast-in-place ground structure, which has higher structural strength than the overhead ground structure but higher cost, so that a specific ground structure type can be selected according to different requirements.

A description will be given of the moisture-proof construction of the cast-in-place floor. In some embodiments of the invention, laying a moisture-proof ground on a foundation comprises the steps of:

backfilling earthwork on the foundation, and tamping in layers to form a first rammed earth layer 110;

paving broken stones on the upper surface of the first plain soil compaction layer 110, and paving fine sand on the broken stones to level the fine sand to form a first rigid layer 120;

laying a first ground film waterproof layer 130 on the upper surface of the first rigid layer 120;

pouring concrete on the upper surface of the first ground thin film waterproof layer 130, placing reinforcing steel bars in the concrete, and forming a second rigid layer 140 after solidification;

coating a waterproof paint on the upper surface of the second rigid layer 140 to form a first floor waterproof paint layer 150;

filling cement mortar on the upper surface of the first floor waterproofing coating layer 150;

paving floor tiles on the upper surface of the cement mortar, and filling and leveling the brick joints by using the cement mortar.

Referring to fig. 2, the earthwork is backfilled and tamped layer by layer, so that the structural strength of the first rammed earth layer 110 can be effectively improved, and the problems that the house main body collapses and the like due to insufficient strength of the first rammed earth layer 110 in the following process are solved. The first rammed earth layer 110 is soft in texture, and therefore, in order to provide a rigid support foundation for the subsequent construction, crushed stones are laid on the first rammed earth layer 110 and leveled with fine sand on the crushed stones to form the first rigid layer 120. In some embodiments of the present invention, the crushed stone laid on the first rammed earth layer 110 is guaranteed to have a thickness of 200mm as much as possible to provide sufficient support strength.

Sufficient flatness and uniformity need to be ensured after fine sand laying is completed to ensure that the first ground film waterproof layer 130 is not damaged when the first ground film waterproof layer 130 is laid. In some embodiments of the present invention, the first ground film waterproof layer 130 is a polyethylene film, and the polyethylene film needs to have a thickness of 0.08mm to 0.1mm, so that the polyethylene film can ensure a certain structural strength to prevent damage during laying, and can also ensure sufficient air permeability and waterproof performance to ensure moisture resistance. The polyethylene film is a flexible material, can prevent the damage of slight deformation, has guaranteed waterproof ability.

After the first floor film waterproof layer 130 is laid, concrete is filled on the upper surface of the first floor film waterproof layer 130 to facilitate the application of the waterproof material. And a single layer of bidirectional reinforcing steel is previously laid in the second rigid layer 140 for the purpose of sufficient overall strength of the finally formed ground. In some embodiments of the present invention, the second rigid layer 140 is cast with 80mm thick C15 concrete to ensure sufficient support strength.

After the second rigid layer 140 is constructed, a waterproof coating material is applied to the upper surface of the second rigid layer 140 to form the first floor waterproof coating layer 150. In some embodiments of the present invention, the first floor waterproofing coating layer 150 uses a polymer cement waterproofing coating, which can be thickly coated for easy construction, and the polymer cement waterproofing coating is also a flexible material, which can prevent damage due to slight deformation, ensuring waterproofing ability. The thickness of the polymer cement waterproof coating is at least 2.0mm to ensure enough waterproof capability.

And finally, filling cement mortar in the first ground waterproof coating layer 150, finishing the laying of the floor tiles, and forming the final moisture-proof ground after solidification. The cement mortar filled in the first floor waterproof coating layer 150 needs to ensure a thickness of 20mm to ensure the smoothness and stability of the floor tile laying.

Through the structure that adopts first rigid layer 120, first ground film waterproof layer 130, second rigid layer 140, first ground waterproof coating layer 150 of interval arrangement in the dampproofing ground, can effectually block steam, make and keep permanent dry dehumidification effect in the house. In the construction process, it is necessary to avoid damaging the first ground film waterproof layer 130 to prevent the effect of blocking moisture from being lowered.

A description will be given here of the moisture protection of the overhead floor. In some embodiments of the invention, laying a moisture-proof ground on a foundation comprises the steps of:

backfilling earthwork on the foundation, and tamping in layers to form a second rammed earth layer 210;

paving prefabricated slabs 220 above the second rammed earth layer 210, and constructing an overhead layer 230 between the prefabricated slabs 220 and the second rammed earth layer 210;

laying a second ground film waterproof layer 240 on the upper surface of the prefabricated panel 220;

pouring concrete on the second ground film waterproof layer 240, placing reinforcing steel bars in the concrete, and forming a third rigid layer 250 after solidification;

the floor tiles are laid on the third rigid layer 250, and the joints of the floor tiles are filled and leveled by using cement mortar.

Referring to fig. 3, the overhead ground also needs to be backfilled with earthwork and tamped layer by layer, so that the structural strength of the second rammed earth layer 210 can be effectively improved, and the problems of collapse of the main body of the house caused by insufficient strength of the second rammed earth layer 210 in the following process and the like are avoided. The texture of the second rammed earth layer 210 is soft, so in order to provide a rigid supporting foundation for the subsequent construction, the prefabricated slab 220 is arranged above the second rammed earth layer 210, an empty layer 230 structure is left between the prefabricated slab 220 and the second rammed earth layer 210, and the prefabricated slab 220 are caulked by fine aggregate concrete, so that a certain moisture-proof effect is achieved by the empty structure.

The prefabricated panel 220 forms a flat structure on which a second ground film waterproof layer 240 may be directly laid. In some embodiments of the present invention, the second ground film waterproof layer 240 is made of polyethylene film or polypropylene fabric, and when the polyethylene film is used, the thickness of the polyethylene film needs to be ensured to be 0.08mm to 0.1mm, so that the polyethylene film can ensure a certain structural strength to prevent damage during laying, and at the same time, the air permeability and waterproof performance of the polyethylene film can be ensured to ensure the moisture-proof capability. The polyethylene film is a flexible material, can prevent the injury of slight deformation, has guaranteed waterproof ability.

After the second ground film waterproof layer 240 is laid, concrete is filled on the upper surface of the second ground film waterproof layer 240, and a bidirectional reinforcing mesh is laid in the concrete in advance, so that the overall structural strength and toughness of the finally formed third rigid layer 250 can be improved. In some embodiments of the present invention, the second rigid layer 140 is cast with C20 concrete with a thickness of 40mm, so as to ensure sufficient supporting strength. Thereafter, the tile is laid on the third rigid layer 250 and the final moisture proof floor is formed.

The structure of the overhead layer 230, the prefabricated plate 220, the second ground film waterproof layer 240 and the third rigid layer 250 which are arranged at intervals in the damp-proof ground can effectively block water vapor, so that the drying and dehumidifying effect in a house can be kept for a long time. In the construction process, the second ground film waterproof layer 240 needs to be prevented from being damaged, and the effect of preventing water vapor from being blocked is reduced.

In some embodiments of the present invention, in constructing the overhead ground, laying a moisture-proof ground on the foundation further comprises the steps of:

coating a waterproof coating layer on the upper surface of the third rigid layer 250 to form a second ground waterproof coating layer;

In actual engineering, a part of areas may have excessive humidity, and after the third rigid layer 250 is built, the upper surface of the third rigid layer 250 is coated with a waterproof coating to form a second ground waterproof coating layer, so that the waterproof capability is further improved integrally. In some embodiments of the invention, the second layer of flooring waterproofing coating uses a polymer cement waterproofing coating. The polymer cement waterproof coating can be thickly coated, is convenient to construct, is also a flexible material, can prevent the damage of slight deformation, and ensures the waterproof capability. The thickness of the polymer cement waterproof coating is at least 2.0mm to ensure enough waterproof capability.

And finally, filling cement mortar in the second waterproof floor coating layer, and finishing the laying of the floor tiles to form the final moisture-proof floor. The cement mortar filled on the second ground waterproof coating layer needs to ensure that the thickness reaches 20mm so as to ensure that the floor tiles are paved smoothly and stably.

In some embodiments of the invention, in order to prevent the damage of the rat and insect, a layer of concrete can be added on the rammed earth layer. The concrete needs to ensure the thickness of 30mm, and C15 concrete is adopted.

In some embodiments of the invention, constructing a roof on a floor comprises the steps of:

laying a reinforced concrete roof panel 310 on the floor slab;

paving cement mortar on the reinforced concrete roof panel 310, and forming a cement mortar slope layer 320 after solidification;

coating waterproof paint on the upper surface of the cement mortar slope layer 320 to form a first roof waterproof layer 330;

Traditional roofing is waterproof, is after building the roof through the timber apron, lays waterproof cloth on the timber structure, then lays the tile and realizes waterproofly, and this kind of mode founds the roofing, and the structure is more weak, and waterproof ability is poor.

Referring to fig. 4, the reinforced concrete roof can effectively improve the structural strength of the roof, but the concrete on the sloping roof is easy to vibrate and is not compact, so that the problem of poor waterproofness is easy to occur on the structure. Therefore, a cement mortar slope layer 320 is added on the roof surface, and a waterproof coating is applied on the cement mortar slope layer 320 to form a first roof waterproof layer 330. In some embodiments of the present invention, the thickness of the cement mortar slope layer 320 is 20mm, and the waterproof coating applied on the cement mortar slope layer 320 is a polyurethane waterproof coating, which can maintain good adhesion with the base layer.

After the first roof waterproof layer 330 is constructed, a waterproof roll material is laid on the first roof waterproof layer 330, and the waterproof roll material forms the second roof waterproof layer 340, so that an excellent waterproof effect is achieved through the laminated structure. In some embodiments of the present invention, the waterproof roll used to construct second roof waterproof layer 340 may be a high-ductility self-adhesive asphalt waterproof roll, which has a certain flexibility and can provide sufficient waterproof effect.

After constructing second roofing waterproof layer 340, can lay the pea gravel concrete on second roofing waterproof layer 340 to lay the battens on the pea gravel concrete, after the pea gravel concrete solidifies like this, alright with forming and holding nail layer 350, and the battens can closely combine with the pea gravel concrete, lay the tile this moment again on the battens alright with the stability of guaranteeing the tile.

In addition, in order to prevent the fine stone concrete from falling off the waterproofing membrane, a reinforcing mesh is laid when the nail holding layer 350 is poured.

In some embodiments of the present invention, the building main body structure building method further includes:

laying a heat-insulating material on the upper surface of the second terrace waterproof layer 420 to form a terrace heat-insulating layer 430;

paving a terrace isolating layer 440 on the upper surface of the terrace insulating layer 430 by using an isolating material;

a deck concrete layer 450 is laid on the upper surface of the deck insulation layer 440.

With the development of economy, the prior village villas are different from the prior villas, and most of the villas are provided with a large terrace on a roof or other floors for leisure and entertainment. Therefore, the waterproof of the terrace is also an important link.

Referring to fig. 5, the terrace is provided on the basis of the floor, so that after the upper surface of the floor is leveled and cleaned, the waterproof coating may be applied to form a first terrace waterproof layer 410, and a waterproof roll may be laid on the first terrace waterproof layer 410 to form a second terrace waterproof layer 420. In some embodiments of the present invention, first terrace waterproof layer 410 is made of polyurethane waterproof paint with a thickness of 2.0mm, and second terrace waterproof layer 420 is made of high-ductility self-adhesive asphalt waterproof roll with a thickness of 2.0mm, which have better waterproof capability and are convenient for construction.

After second deck waterproof layer 420 is laid, deck insulating layer 430 may be laid on second deck waterproof layer 420 in order to improve the insulating effect. In some embodiments of the present invention, the terrace insulation layer 430 is made of hydrophobic expanded perlite with a thickness of 30mm, which can provide excellent insulation.

A layer of isolation material is further laid on the terrace isolation layer 440 to be used as the terrace isolation layer 440, and then a terrace concrete layer 450 is laid on the terrace isolation layer 440 to complete the waterproof construction of the whole terrace. In some embodiments of the present invention, the terrace insulation layer 440 uses a non-woven polyester cloth, which has a good insulation effect and can be used for waterproofing. The thickness of the terrace concrete layer 450 laid on the uppermost layer needs to reach 40mm, the terrace concrete layer is used as a slope finding layer, and a reinforcing mesh needs to be added inside the terrace concrete layer for reinforcement.

In some embodiments of the present invention, the building main body structure building method further includes: set up direct drainage structure in the space is laid to the balcony, direct drainage structure's inlet opening and balcony concrete layer 450 parallel and level, direct drainage structure's drain pipe is buried underground in the wall body.

The side drainage structure that traditional balcony drainage structures adopted appears the jam phenomenon easily under the long-term influence of fallen leaves, laying dust, and the drain pipe among the balcony drainage structures of present rural villa is mostly buried underground in the wall body, consequently leads to balcony drainage structures to be difficult to the clearance easily. The problem can be effectively avoided by adopting a direct drainage structure. The water inlet of the direct drainage structure is flush with the terrace platform which is finally formed, so that the appearance is ensured. In the construction, the terrace concrete layer 450 is plugged up only by the flush, so that the water inlet can be prevented from being made by cement and the like.

reserving a windowsill laying space on a wall body;

paving fine stone reinforced concrete on the windowsill paving space, and forming a windowsill beam 610 after solidification;

sequentially paving a windowsill cement mortar bedding bottom layer 620 and a windowsill waterproof bedding bottom layer 630 on the windowsill beam 610; the cement mortar bedding layer and the sill waterproof bedding layer 630 both have an inclination angle toward the outside of the sill and downward;

installing the window frame on the waterproof pad bottom layer 630 of the windowsill, and laying a windowsill panel 640 on the waterproof pad bottom layer 630 of the windowsill;

a gap between the sill and the sill panel 640 is filled with a waterproof material and sealed with a watertight adhesive.

The windowsill is a part directly facing rainwater erosion, and the traditional windowsill structure is not subjected to waterproof treatment or is simply sealed by adopting cement, so that water seepage is difficult to avoid, and damage to the windowsill and a wall body is easily caused in the past. Therefore, the windowsill also needs to be waterproofed. Referring to fig. 7, in a windowsill-laying space reserved on a wall body, a windowsill beam 610 is first constructed using fine stone reinforced concrete for subsequent installation of the windowsill. A cement mortar bedding layer and a windowsill waterproof bedding layer 630 are sequentially constructed on the windowsill beam 610 to protect the wall and prevent the wall from being damaged by water seepage. And then, installing a windowsill on the windowsill waterproof pad bottom layer 630, and laying a windowsill panel 640, wherein gaps exist among the windowsill waterproof pad bottom layer 630, the windowsill and the windowsill panel 640 in the process, the gaps are filled with waterproof materials, and then, watertight glue is used for further watertight treatment. In some embodiments of the present invention, sill flashing bottom layer 630 is constructed using a polymeric flashing mortar, the flashing material filling the gap is also a polymeric flashing mortar, and the water-tight glue is weatherproof glue. In addition, sill beam 610, cement mortar underlayment and sill waterproofing underlayment 630 will maintain an outward angle of inclination to ensure that water does not accumulate on the sill.

and coating the outer side of the wall body with an outer wall coating material.

The outer wall surface of the main villa body needs to be plastered, so that the direct corrosion of rainwater to the outer wall can be reduced. And the outer wall is because need expose for a long time in the rainwater, consequently need carry out certain waterproof treatment, rural country villa adopts the ceramic tile laminating mostly on the outer wall surface, and the ceramic tile laminating cost is higher, and in case the ceramic tile drops and takes place the accident easily, and is difficult to find the ceramic tile of replacement, even find the replacement ceramic tile, the cost of laminating again is also extremely high. Also someone directly uses cement wall, but traditional cement wall's water-proof effects is poor, appears the outer wall fracture easily. The mode that the polypropylene fiber and the waterproof agent are added in the cement mortar to be mixed into the outer wall coating material is adopted, and the outer wall coating material after mixing and modulation is coated on the outer wall, so that the waterproof effect can be effectively improved. In some embodiments of the invention, the exterior wall coating material is formed by mixing polypropylene fibers and 40% of waterproof agent in cement mortar, and has excellent waterproof effect.

In addition, if the outer wall coating materials are directly coated on the joints among the wall surface, the constructional columns and the frame columns, the strength of the outer wall coating materials coated on the outer wall is not enough due to dislocation, and therefore the matrix bonding reinforcing steel wire meshes are arranged on the joints among the wall surface, the constructional columns and the frame columns, and the bonding capability of the outer wall coating materials is improved.
