Description

House building method

Technical Field

The application relates to the technical field of house construction, in particular to a house construction method.

Background

With the development of science and technology, house construction methods have also gone through a number of stages, including thatch house construction, mud tile house construction, brick tile prefabricated house construction, brick-concrete house construction, frame cast-in-place house construction, heavy steel structure house construction, and the light steel structure house construction of the current state.

The thatch house and the clay tile house are basically eliminated, and even in rural areas, the insidious marks are almost eliminated; existing brick houses and prefabricated brick houses have been the last century. The newly constructed houses are generally constructed by adopting brick-concrete houses and frame cast-in-place houses, and the brick-concrete houses and the frame cast-in-place houses are similar to each other in that reinforced concrete is used as a basic frame for building the houses, but the brick-concrete houses are constructed by adopting bricks for building walls or non-bearing walls. Heavy steel structural houses are often referred to as large buildings, such as high-speed rail stations, airports, etc. At present, a building method which is newly developed in recent years is a light steel house building method, a wall structure system of a light steel house is jointly stressed by light steel ribbed beams and columns and a maintenance structure, various physical performance indexes are excellent, the construction period is short, the heat insulation effect is good, and the light steel house building method is a novel green, energy-saving and environment-friendly building structure system. The outer wall system is generally between 120-200mm, and because the wall body is light and thin, the actual use area of the light steel structure house is increased by about 10-15% compared with the traditional house, the indoor use area is increased by more than 90% compared with the traditional house, and the indoor space can be flexibly divided. The pipeline can be arranged in the holes reserved in the wall, the floor and the roof component, and has good concealment and more attractive appearance.

However, on one hand, the light steel structure house has limited bearing capacity and is relatively troublesome in construction process, and although the light steel structure house can well utilize the mutual supporting function among the whole structures; however, the light steel house is easily collapsed before the integral molding, and a construction accident in which the house is collapsed during the construction of the light steel house often occurs. On the other hand, the light steel structure house is generally decorated on the wall surface or the outer wall after the basic structure of the house is built, namely after a blank is built; building waste is easily generated in the decoration process, the decoration process is time-consuming and labor-consuming, and labor and material costs are indirectly increased.

Disclosure of Invention

The object of the present application is to provide a new house building method.

The following technical scheme is adopted in the application:

the application discloses a house building method, which comprises the steps of installing a plate which is prepared in advance and has good linearity, flatness and strength after being cut and folded as a wall body on a connecting structure, and assembling into a house prototype with a box-type structure; in the house prototype with the box-type structure, the plates are fixedly connected with the ground through a reserved connecting structure, the plates are connected and enclosed into a wall body through a bent clamping structure, and a connecting structure for connecting a floor panel and a connecting structure for connecting an upper-layer wall body are reserved at the top end of each plate; installing a wall tile pendant bracket on a plate, then installing an inner wall tile and/or an outer wall tile on the wall tile pendant bracket, and then filling filler into a cavity between the wall tile and the plate, so that the wall tile, the filler and the plate are pasted into an integrated structure to form a final wall body of a house; the method comprises the following steps of (1) installing a pre-prepared plate with good linearity, flatness and strength after being cut and folded as a floor panel on a connecting structure which is reserved at the top end of the plate used as a wall and is connected with the floor panel, installing a floor tile bracket on the floor panel, installing floor tiles on the floor tile bracket, and filling filler into a cavity between the floor tiles and the floor panel to enable the floor tiles, the filler and the plate to be adhered into an integral structure to form a final floor slab of a house; the construction of the walls and the floor slabs of all the floors is completed according to the method, so that the overall decoration of the house is synchronously completed while the main construction of the house is completed.

The house building method adopts the pre-prepared plates, and only simple splicing is needed in the whole building process, so that the house building method is simple and convenient to operate, free of building garbage pollution and more environment-friendly; more importantly, the method is easy for industrialized and standardized production, so that the house construction not only greatly saves labor, but also almost has no construction waste, and better meets the requirement characteristic of building environmental protection. According to the house building method, the whole structure of the house is built, meanwhile, the outer wall surface, the indoor wall surface and the floor are decorated, and building and decoration of the house are almost simultaneously carried out.

The key point of the application is to creatively propose that the decoration of the inner wall, the outer wall and the floor is carried out while the main body structure is built; in addition, the wall tiles and the floor tiles are further reinforced to form stable final walls and final floors when being decorated; that is, the main structure construction and the wall and floor decoration are complementary. As for the wall tile pendant bracket and the floor tile bracket specifically adopted in the building construction method, the existing mounting bracket can be referred to; the wall tiles and floor tiles can also be conventional plates, such as ceramic, marble, metal, plastic or composite materials; the filling filler can be various materials which are easy to fill and meet the performance requirements of strength, heat preservation, sound insulation and the like required by building design; and is not particularly limited herein. However, in order to make building construction simpler, in a preferred embodiment of the present application, a wall tile hanger bracket and a method of installing a wall tile are particularly limited, and in another preferred embodiment, a floor tile bracket and a method of installing a floor tile are particularly limited, which will be described in detail in the following technical solutions.

It should be noted that the building construction method of the present application, similar to the sandwich construction structure and method, uses the prefabricated plate as the skeleton, such as metal plate or plate rib, and then uses the support to lay the floor tile and wall tile, and finally fills and fixes them to form the stable wall and floor. The house building method can omit a plurality of working procedures, for example, a steel bar worker, a template worker, a mortar batching and leveling worker and a form removing worker are not needed; meanwhile, a lot of auxiliary materials can be reduced; in addition, the whole house is built more cleanly and neatly due to the omission of the working procedures and auxiliary materials. In the subsequent improvement of the application, the special method of paving the wall tiles and the floor tiles is adopted, so that the technical requirements on the paving of the floor tiles and the paving of the wall tiles are greatly reduced; the laying of the floor tiles and the wall tiles is simpler and easier to operate.

In one implementation of the present application, the plate material as the wall body is a metal plate, and the plate material as the floor panel may also be a metal plate.

The plate material of the present application may be a plate material having the same characteristics, or a plate material of a different material having the same characteristics after being processed by shearing or the like, in the form of waves, cross-waves, or the like, other than the metal plate. The metal plate is preferably used in the present application, on one hand, the metal plate is easy to process into various required structures, such as a bent clamping structure required in the present application or other connecting structures, in view of the convenience of processing; on the other hand, the metal plate has better strength and stability, and better linearity and flatness, and can well meet the use requirements of the house building method.

In one implementation mode of the application, the wall tile pendant bracket is of a strip structure, and one end of the wall tile pendant bracket is provided with a first through hole, so that the wall tile pendant bracket is fixed on a wall body by adopting a screw; the other end of the wall tile hanging bracket is a side-lying I-shaped wall tile bayonet used for supporting the wall tile; in addition, a second through hole is formed in a symmetrical shaft of the bayonet structure of the laterally-lying I-shaped wall tile, so that the space between the bayonet of the wall tile and the wall body can be conveniently adjusted when the wall tile hanging bracket is fixed on the wall body, and the leveling of the wall tile is conveniently carried out; during the use, through the fixed wall tile of two rows of wall tile pendant supports from top to bottom, concrete, the lower half of the side "worker" font's of going up the wall tile pendant support wall tile bayonet socket joint upper portion edge of wall tile, the upper half of the side "worker" font's of the wall tile bayonet socket of going down the wall tile pendant support wall tile bayonet socket of going down the wall tile.

In one implementation mode of the application, the wall tile hanging bracket is arranged at the I-shaped wall tile bayonet, and a part of the wall tile bayonet close to a wall body is provided with a protrusion after extending downwards for a certain distance along the length direction of the wall tile hanging bracket during installation; the bulge is used for being inserted into the wall tile and plays a role in fixing.

It should be noted that the wall tile pendant bracket of the application is provided with a bulge below the I-shaped wall tile bayonet for fixing the wall tile, and the wall tile can be further supported under the condition that the bonding performance of the filler is reduced, so that the wall tile is prevented from falling. It can be understood that the design of the convex structure can be determined according to the requirement, and under the condition that the requirement for paving the wall tiles is high or the weight of the wall tiles is large, the design of the convex structure is recommended to be added. It can be understood that if the projection design is adopted, correspondingly, when the wall tiles are installed, the wall tiles need to be grooved at corresponding positions, so that the projections of the outer hanging piece can be accurately inserted into the wall tiles.

In an implementation of this application, adopt wall tile pendant support to carry out the wall tile installation and specifically include following step:

the wall tile hanging bracket is fixed on the wall body by adopting a screw through a first through hole of the wall tile hanging bracket, and the side-lying H-shaped wall tile bayonets of each row of wall tile hanging brackets are kept on the same straight line;

the second through holes of the wall tile hanging piece brackets are fixed by screws, and the depth of the wall tile hanging piece brackets is driven into the wall body by adjusting screws to adjust the interval between the wall tile bayonets and the wall body, so that the leveling of the wall tile bayonets of all the wall tile hanging piece brackets is realized;

installing the wall tiles between the upper row of wall tile hanging bracket and the lower row of wall tile hanging bracket, finely adjusting screws for fixing second through holes of the wall tile hanging brackets, and leveling the laid wall tiles;

after the wall tiles are leveled, the cavity between the wall tiles and the plate is filled with filler, so that the wall tiles are firmly stuck to the surface of the plate.

It should be noted that, when practical laying is performed, for convenience of filling, 1-2 rows of the actual laying can be laid in advance, then filling is performed, and then subsequent laying is performed; or reserving a vacant space of the wall tile to facilitate filling of the filler; the concrete conditions may be determined according to actual laying conditions, and are not particularly limited herein. The spacing between the wall tile hanger brackets in each row, and the spacing between the wall tile hanger brackets in both rows, is dependent upon the particular size of the wall tile and is not specifically limited herein.

It should be noted that the key of the method for paving the wall tiles is to use a specially designed wall tile hanging bracket. In this application, the side-lying "i" shaped bayonet structure of the wall tile pendant bracket means that the tangent plane of the end part of the wall tile pendant bracket is the side-lying "i" shaped bayonet structure of the wall tile. It will be appreciated that the thickness and width of the wall tile hanger bracket of the present application will depend on the desired load bearing capacity, and that the wall tile hanger bracket may be designed to be thicker and wider for larger sizes of wall tiles, for example, the width of the wall tile hanger bracket is less than or equal to the width of the wall tile, or 1/2, 1/3, 1/4, 1/5, 1/10, 1/20, 1/40, etc., which is not specifically limited herein. It can be understood that the larger the width of the wall tile hanging bracket is, the better the supporting effect on the wall tiles is; however, the material cost is correspondingly increased; moreover, if the wall tile hanging piece bracket is too wide, the number of the first through holes and the second through holes needs to be increased, so that leveling is not facilitated; in principle, the width of the wall tile pendant bracket is preferably 1-5cm, and if the bearing capacity needs to be enhanced, the wall tile pendant bracket can be adjusted by increasing the thickness of the wall tile pendant bracket.

As for the length of the wall tile pendant bracket, the distance between the first through hole and the second through hole is directly influenced; one key point of the application is that the wall tile pendant bracket adopts two stress points, so that the wall tile pendant bracket is more stable; thus, the length of the wall tile hanger bracket may also be such that the force points are spread out as much as possible with reference to the size of the wall tile, i.e. the distance between the first through hole and the second through hole is as large as possible, e.g. the length of the wall tile hanger bracket is designed to be 1/5 to 1/2 of the size of the wall tile. In addition, the length of the wall tile hanger bracket also affects the bearing capacity of the wall tile hanger bracket, for example, the longer and the more slender the wall tile hanger bracket is, the easier the wall tile hanger bracket is to break, therefore, the length of the wall tile hanger bracket should be within the bearing capacity range, and is not limited in particular. Of course, the width and thickness of the wall tile hanger bracket have a more direct and greater impact on the bearing capacity; therefore, as long as the width and the thickness of the wall tile pendant bracket are ensured, the length of the wall tile pendant bracket can be designed according to requirements, and the problem of fracture caused by too long is not worried.

It should be noted that, in the method for paving the wall tile, due to the adoption of the wall tile pendant bracket specially designed in the application, compared with the existing wall tile paving, the paving method adopted in the application can be operated only by adopting a simple wall tile pendant bracket without a complex external hanging frame; adopt the wall tile pendant support of this application, the interval between wall tile and the wall body can be very little, and both's interval is wall tile pendant support's thickness or slightly bigger than wall tile pendant support thickness exactly basically, consequently, does not need very big space, and the filling cost is low, and the construction degree of difficulty is little. Therefore, the method for paving the wall tiles adopts the wall tile hanging piece support and the filling material to paste to carry out double fixation on the wall tiles, and the wall tiles and the wall body are fixed and bonded in a comprehensive and integrated mode, so that the wall tiles are not easy to drop even if the wall tiles are broken into small blocks, and the potential safety hazard that the wall tiles are broken and drop is solved. In addition, the wall tile pendant bracket is small and exquisite, easy to operate, low in material cost and construction cost, capable of being fixed only by screws and conveniently leveled only by adjusting the screws, simple and convenient to operate and low in technical requirements on constructors; in addition, the wall tile is paved by adopting the wall tile hanging bracket, integral construction is not needed, one-step forming is not needed, the bayonet of the wall tile hanging bracket can be leveled firstly during leveling, and after the wall tile is installed, fine adjustment and leveling can be performed through screws, for example, the screws for fixing the second through holes are adjusted; the wall tile hanging piece supports can be installed and the wall tiles can be laid in a row, so that the construction is more flexible. Generally speaking, a wall tile can adopt two upper and lower rows, and four wall tile pendant supports in total support fixedly, and four wall tile pendant supports evenly distributed are in four angles of wall tile or be close to the place at four angles. In a word, the wall tile is paved by adopting the wall tile hanging piece support, so that the wall tile paving quality and efficiency can be better guaranteed, the technical level dependence on constructors is reduced, and the standardized operation is easy.

In one implementation manner of the application, one end of the top of the screw fixed by the second through hole is provided with a first external thread, the tail end of the screw is provided with a wrenching structure, a part close to the tail end is provided with a second external thread, and the thread directions of the first external thread and the second external thread are opposite; the second through hole has an internal thread matching the second external thread.

It should be noted that, the screw with threads at both ends and opposite thread directions is used for fixing the second through hole; when the wall tile hanging bracket is used, the wall tile hanging bracket and the wall surface can be moved in the opposite direction or in the opposite direction by rotating the screw, so that the effect of adjusting the gap between the wall tile hanging bracket or the wall tile and the wall body is achieved, and the leveling can be conveniently carried out. It can be understood that in principle, the spacing between the wall tile hanging bracket or the wall tile and the wall can be adjusted by screwing the screw into the wall or screwing the screw out of the wall, so that the leveling effect is achieved, and only one end of the mode moves; this application adopts the screw of both ends screw thread opposite direction, and when this screw was rotated, both ends were relative movement together like this, can improve fine setting efficiency and fine setting range, conveniently make level.

It should be further noted that the screw for fixing the second through hole is a specially designed screw, so that leveling is facilitated; as for the screw fixing the first through hole, a conventional screw or an expansion screw may be used, which is not particularly limited herein.

Preferably, the top of the screw fixed by the second through hole is in a sharp structure.

It should be noted that, in the present application, the top of the screw fixed by the second through hole may be a sharp structure or a flat structure; the sharp-pointed structure can conveniently be hit the screw into the wall body, if the flat head structure then need punch in advance to supporting expansion pipe is firm.

Preferably, the screwing structure of the screw fixed by the second through hole is a straight groove, a cross groove H shape, a cross groove Z shape, a cross groove F shape, a square groove, a composite groove, an internal spline, an internal hexagonal flower shape, an internal triangle, an internal hexagonal, an internal 12-degree angle, a six-blade groove or a high-torque cross groove.

Preferably, the second through hole is used for fixing the screw, and a cylinder between the first external thread and the second external thread is a flat cylinder or a polygonal cylinder.

The screw fixed by the second through hole has the function of adjusting and flatly paving the wall tiles by rotating the screw, and the screw is generally rotated by a wrenching structure during adjustment; however, under the condition that the fine adjustment by the wrenching structure is difficult or inconvenient, the fine adjustment can be conveniently performed by rotating the screw by a wrench through the flat cylinder or the polygonal cylinder between the first external thread and the second external thread in the preferred modification of the present application.

Preferably, the wall tile pendant bracket is an integrated structure made of metal, plastic or ceramic.

More preferably, the wall tile pendant support is an integrated structure made of aluminum profiles.

It should be noted that the wall tile pendant bracket of the present application is made of aluminum profiles or plastics, which is mainly convenient for production and low in cost, and does not exclude that other known materials can be used for preparing the wall tile pendant bracket of the present application, and is not specifically limited herein.

In one implementation of the present application, a floor tile bracket is installed on a floor panel, and then floor tiles are installed on the floor tile bracket, specifically including driving a tapping screw into the floor panel where the floor tiles are to be laid according to a desired position; installing a nut structural component matched with the self-tapping screw on the self-tapping screw to form a structural component bracket capable of supporting and positioning floor tiles; positioning and leveling the nut structure components on all the structure component brackets; laying the floor tiles on the structural component support which is positioned and leveled; the floor tiles are finely adjusted by rotating the self-tapping screws combined with the nut structure components, so that the flatness and the positioning accuracy of the laid floor tiles are improved; then, filling filler into the cavity between the floor tiles and the floor panel, and sticking the floor tiles and the floor panel into an integrated structure.

The floor tile laying method is different from the existing wet laying and dry laying, the floor tiles are supported and fixed in advance by the aid of the structural component support, and the floor tiles are guaranteed to have excellent smoothness and stability after being laid and attached through twice leveling; moreover, the two-time leveling can be realized only by rotating the self-tapping screw or the nut structural component, and the operation is simple and convenient. Finally, because the floor tiles after being paved are doubly fixed by the filling filler and the structural component bracket, the floor tiles are more stable than the traditional paving mode. The floor tile laying method has low technical requirements on constructors, and can be used for simple training; and the leveling and filling modes are simple, so that the laying quality and efficiency of the floor tiles can be ensured.

It can be understood that, for the traditional paving and pasting mode, when the floor tiles are paved, constructors need to repeatedly scrape cement and continuously beat and level the floor tiles by using small hammers, and the paving and pasting technical requirements of the constructors are high in practice so as to ensure that the floor tiles are finally paved and leveled; and also affects the efficiency of the floor tile laying. The floor tile paving and pasting method can be used for conveniently and visually leveling and fixing the floor tiles only by adjusting the self-tapping screws during operation.

In addition, during construction, in order to avoid floor tile movement caused by filling, a certain pressure can be applied to the floor tiles in advance, or a small amount of glue or cement is adopted to fix the floor tiles on the structural component bracket preliminarily, or a groove can be formed in the floor tiles in advance to clamp the structure on the structural component bracket; the concrete conditions may be determined according to the site construction conditions, as long as the slab brick can be prevented from shifting during filling, and are not particularly limited herein.

In one implementation of the present application, one end of the top of the self-tapping screw has a first external thread; the tail end of the self-tapping screw is provided with a wrenching structure, and the part close to the tail end is provided with a second external thread; and the thread directions of the first external thread and the second external thread are opposite.

It should be noted that, the application creatively designs the helicitic texture at self-tapping screw's both ends to the screw thread at both ends designs for opposite screw thread direction respectively, and when using like this, just can realize moving in opposite directions or back of nut structure subassembly and floor through rotatory self-tapping screw, plays the effect of adjustment floor tile and floor's clearance and height, thereby can be convenient make level. It can be understood that in principle, the height of the floor tiles can be adjusted by screwing the tapping screws into the floor or screwing the tapping screws out of the floor, so that the leveling effect is achieved, and only one end of the floor tiles moves in the mode; the self-tapping screw with opposite thread directions at two ends is creatively designed, so that when the self-tapping screw is rotated, the two ends are moved relatively together, the fine adjustment efficiency and the fine adjustment range can be improved, and the leveling is convenient.

In one implementation of the present application, the second external thread portion of the self-tapping screw has a larger diameter than the first external thread portion, so that the nut component can be threaded through the top end of the self-tapping screw and then screwed into the second external thread position.

In one implementation of the present application, the screwing structure of the tapping screw is a straight groove, a cross groove H-shaped, a cross groove Z-shaped, a cross groove F-shaped, a square groove, a composite groove, an internal spline, an internal hexagonal flower shape, an internal triangle, an internal hexagonal, an internal 12-degree angle, a six-blade groove, or a high-torque cross groove. It is to be understood that the key to the present application is to design the thread structures with opposite thread directions at both ends of the tapping screw, and as for the screwing structure of the tapping screw, reference may be made to the existing screw structure.

In one implementation of the present application, the post between the first external thread and the second external thread of the tapping screw is a flat post or a polygonal post.

It should be noted that, when the tapping screw is rotated, the screwing is generally performed by the wrenching structure; however, in the case where it is difficult or inconvenient to perform fine adjustment by rotating the tapping screw with the tapping screw wrenching structure, fine adjustment can be performed by rotating the tapping screw with a wrench conveniently by using a flat cylinder or a polygonal cylinder between the first external thread and the second external thread in a preferred modification of the present invention.

In one implementation of the present application, the geometric center of the nut structural component has a screw hole, the internal thread of the screw hole matches with the second external thread of the tail of the self-tapping screw. The screw hole is a through hole penetrating through the nut structural component, so that the self-tapping screw can still be rotated through the screwing structure of the self-tapping screw after the nut structural component is installed on the self-tapping screw.

In one implementation of the present application, the geometric center of the nut structure assembly is an upwardly or downwardly convex structure, and the periphery of the convex structure has a mounting plane of the floor tiles disposed on the same horizontal plane. The nut structure component is characterized in that the geometric center of the nut structure component is designed into a convex structure, so that the stability of combination of the nut structure component and the self-tapping screw can be enhanced; on the other hand, when the convex structure is convex upwards, the floor tile has the limiting function. Of course, other methods can be adopted for limiting, such as processing side grooves on four corners of the floor tile to adapt to the installation plane of the nut structure component; a downwardly convex design may be used.

In one implementation of the present application, the geometric center of the nut structure assembly has an "i" shaped detent structure. It should be noted that, the nut structure component is designed into an I-shaped clamping structure, so that the floor tiles can be limited on one hand; on the other hand, can also realize better fixed action through the screens structure.

In one implementation of the present application, the filler between the wall tiles and the panels and the filler between the floor tiles and the floor panels are each independently at least one selected from the group consisting of foaming glue, foaming cement and self-leveling grout.

It should be noted that specific fillers of the present application can be referred to existing building fillers including, but not limited to, foamed rubber, foamed cement, and self-leveling grout. It will be appreciated that any filler that can be conveniently flowed and filled into a small void can be used in this application as long as it can support and stabilize the wall tile after setting.

The beneficial effect of this application lies in:

according to the house building method, the prefabricated plates are directly adopted for simple splicing to complete house building, the operation is simple and convenient, standardized production is easy, and a large amount of labor can be saved; in addition, in the building process, the decoration of the inner wall, the outer wall and the floor of the house is finished simultaneously, so that the building and the decoration of the house can be finished synchronously, and the building construction period is greatly shortened. The house building method is simple and convenient to operate, and easy to standardize and industrially produce; moreover, almost no construction waste is generated, and the requirement of environment-friendly buildings is met.
