Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a slab-concrete structure building system. Background Technology

[0002] In particular, in rural housing construction projects, farmers have a special preference for "brick-concrete structure" because they believe it is relatively stable and easy to accept in terms of concept and habit. Therefore, most farmers are now accustomed to using "brick-concrete structure" to build houses.

[0003] However, traditional viscous bricks in "brick-concrete structures" consume a significant amount of clay annually. Although many modern technologies reduce clay usage, the sintering process still results in considerable waste, leading to resource scarcity and making it an unsustainable structure. Furthermore, the quality of brick wall construction is heavily influenced by the skill of the bricklayers, and the on-site mixing of mortar also requires specific technical expertise, which significantly affects the quality of the brickwork.

[0004] Secondly, brick walls are still constructed manually, and the work of plastering interior and exterior walls, supporting structural columns and ring beams also requires manual labor. Because much of this is done manually, the construction speed is slow. In addition, the brick mortar needs time to cure during the bricklaying process, and decoration can only be carried out after the brick walls and plaster have dried. It is generally impossible to renovate a house in less than six months.

[0005] Furthermore, traditional brick walls require formwork, and the construction of brick walls requires a large amount of scaffolding. The formwork requires a lot of support, and the dismantling of the formwork will increase construction costs.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0064] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0065] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0066] like Figures 1 to 20As shown in the illustration, this application provides a slab-concrete structure building system, including a wall panel assembly 1, a precast formwork assembly, and precast floor slabs 3. The wall panel assembly 1 includes multiple wall panels 1, each of which includes an exterior wall panel 11, a partition wall panel 12, and a door / window wall panel 13. The precast formwork assembly includes multiple formworks, each of which includes a ring beam formwork 21, a corner structural column formwork 22, a straight structural column formwork 23, an independent column formwork 24, a cantilever beam formwork, a closed beam formwork 2501, a main beam formwork 2502, and a secondary beam formwork 2503. The wall panel assembly 1 and the precast formwork assembly are connected to form a wall-column-beam structure of the building. The wall-column-beam structure has a casting cavity for filling with concrete. The precast floor slabs 3 are placed on top of the wall-column-beam structure and are connected to it.

[0067] The slab-concrete structure building system provided in this application replaces traditional clay bricks with a composite wall panel 1 that is an integral part of the thermal insulation template wall panel 1, and replaces the traditional formwork process with the prefabricated, non-removable template in the wall panel 1. Other elements that should be present in a "brick-concrete structure", such as ring beams, ground beams, and structural columns, remain unchanged, and the structural form is closest to that of a "brick-concrete structure".

[0068] Building upon the above, wall panel 1 replaces traditional bricks, reducing clay consumption and resource waste. Wall panel 1 is manufactured in a factory to control quality, ensuring uniformity. During on-site installation, modular fabrication using hoisting and precast formwork components reduces labor and time costs. Furthermore, the formwork casting connection function of wall panel 1, precast formwork components, and precast floor slabs 3 replaces the traditional formwork and support for ring beams and structural columns, eliminating the need for dismantling. Independent column formwork 24, cantilever beam formwork, closed beam formwork 2501, main beam formwork 2502, and secondary beam formwork 2503 can replace the formwork for main beams and cantilever beams, eliminating the need for supporting structures and subsequent formwork dismantling, further reducing labor and time costs.

[0069] In some possible implementations, a gap exists between two partially perpendicular wall panels 1 in the wall panel 1 assembly. The corner structural column formwork 22 includes two L-shaped plates 221, which are respectively connected to the two wall panels 1. The two L-shaped plates 221 are located on both sides in the wall thickness direction, forming a corner cavity between them. A corner column reinforcing bar 4 is provided in the corner cavity, and the corner column reinforcing bar 4 is connected to the reinforcing bar 5 of the wall panel. Concrete is poured into the corner cavity. The reinforcing bar and concrete in the corner cavity firmly connect the two perpendicularly distributed wall panels 1. The corner structural column formwork 22 composed of the two L-shaped plates 221 does not require a supporting structure for support, and the formwork does not need to be disassembled later, greatly reducing labor and time costs during construction.

[0070] In some possible implementations, the wall panel 1 assembly has gaps between some adjacent wall panels 1 located in the same plane. The straight structural column formwork 23 includes two parallel plates 231, which are located on both sides of the wall panel 1, forming a structural column cavity between the two plates 231 and the two wall panels 1. The structural column reinforcement 6 is located inside the structural column cavity, and concrete is poured inside the structural column cavity. The reinforcement and concrete between the two plates 231 of the straight structural column formwork 23 securely connect the two wall panels 1 with gaps. The straight structural column formwork 23 does not require a supporting structure for support, and the formwork does not need to be dismantled later, which can greatly reduce labor and time costs during construction.

[0071] In some possible implementations, the wall panel 1 has a groove 101 on one edge and a base 102 on another edge. The base 102 on one of the two wall panels 1 that are to be joined is embedded in the groove 101 on the other, and the space between the base 102 and the groove 101 is filled with adhesive mortar.

[0072] The edge of the wall panel 1 is provided with a protruding strip with a thickness less than the thickness of the main body of the wall panel 1. The groove width of the groove 101 is matched with the width of the mounting plate 102. After the mounting plate 102 on one of the two wall panels 1 is embedded into the groove 101 on the other, the outer surfaces of the two wall panels 1 are in the same plane. This structure is aesthetically pleasing and makes subsequent wall decoration more convenient.

[0073] The space between the base 102 and the groove 101 is filled with adhesive sand. The adhesive mortar is used to initially fix the base 102 and the groove 101 during the initial connection. This can prevent misalignment such as tilting or sliding during the installation of the base 102 and the groove 101, making the installation of the wall more convenient.

[0074] In some possible implementations, the wall panel 1 is provided with a fixture 7 tooling hole 103 and a lifting hole 104. The fixture 7 is connected to the fixture 7 tooling hole 103 to clamp and fix adjacent wall panels 1 and / or the mold shell between adjacent wall panels 1.

[0075] The straight structural column formwork 23 is set on both sides of the wall panel 1 mounting base 102. The straight structural column formwork 23 is flush with the outer surface of the wall panel 1 and is not easy to connect. The main function of the clamp 7 is to connect the straight structural column formwork 23 to the wall panel 1. The tooling hole 103 of the clamp 7 can facilitate the fixing of the clamp 7. The lifting hole 104 facilitates the fixing of the connection structure of the lifting device.

[0076] The fixture 7 can be any suitable fixture 7 that is already mature in the existing technology.

[0077] In some possible implementations, the ring beam formwork 21 includes a bottom groove 2101 and a top groove 2102. The bottom groove 2101 covers the upper edge of the wall panel 1, and the top groove 2102 is filled with ring beam concrete. When installing the ring beam formwork onto the wall panel 1 and preparing the ring beam, adhesive mortar is applied to the upper end of the wall panel 1, the ring beam formwork is placed on the wall panel 1, and the upper end of the formwork is embedded in the bottom groove 2101 of the ring beam formwork. Then, the ring beam formwork is connected to the wall panel 1 using connectors, and then ring beam concrete is injected into the top groove 2102. Once the ring beam concrete has solidified and reached its strength, the ring beam is complete.

[0078] The width of the bottom groove 2101 of the ring beam formwork 21 is adapted to the width of the wall to which it is installed. When the ring beam formwork is installed onto the wall panel 1, the top of the wall panel 1 is embedded in the bottom groove 2101, which acts as a limit, allowing the ring beam formwork to be quickly installed onto the wall panel 1 without the need for calibration tools, and ensuring accurate alignment between the ring beam formwork and the wall panel 1. This significantly saves manpower, resources, and time, and improves the quality and aesthetics of the finished ring beam.

[0079] In some possible implementations, the ring beam mold shell 21 includes two side plates 211 and a connecting plate 212 located between and connecting the two side plates 211 respectively. The two side plates 211 form a top groove 2102 and a bottom groove 2101 on opposite sides of the connecting plate 212 along its thickness direction. This structure is simple, the manufacturing process is simple, and the positioning effect is good. Furthermore, the ring beam mold shell 21 can be integrally cast, with the two side plates 211 and the connecting plate 212 being integral, further improving the overall structural strength and reducing production difficulty.

[0080] In some possible implementations, the connecting plate 212 is provided with a plurality of fixing holes 2121, which are spaced apart sequentially along the length of the connecting plate 212. The fixing holes 2121 allow fasteners to easily pass through the connecting plate 212 and connect to the wall panel 1. The fasteners can be one of expansion bolts, cement bolts, or wire rope clips. One end of the fastener passes through the fixing hole 2121 and is fixedly connected to the wall panel 1, while the other end of the fastener is confined to the side of the connecting plate 212 away from the wall panel 1.

[0081] In some possible implementations, the width of the bottom groove 2101 gradually increases from its bottom to its opening. This serves as a guide when the ring beam membrane shell is installed onto the wall panel 1, and also provides a certain degree of automatic calibration and positioning, making the installation of the ring beam membrane shell more convenient and the position more accurate. Similarly, the width of the top groove 2102 gradually increases from its bottom to its opening, making it less likely for voids to form when concrete is injected into the top groove 2102.

[0082] In some possible implementations, the independent column formwork 24 includes two corner plates 241, which enclose an independent column cavity, into which independent column concrete is poured.

[0083] Furthermore, a splicing edge 2411 is provided on one side edge of the corner plate 241. When two corner plates 241 are spliced ​​together, the splicing edge 2411 of one corner plate 241 fits against the other side edge of the other corner plate 241. The splicing edge 2411 has a positioning effect, so that the two corner plates 241 are accurately positioned when spliced ​​together, and the splicing is convenient.

[0084] Furthermore, when the two corner plates 241 are spliced, clamping plates are set on the outer periphery to ensure that the splicing of the independent column mold shell 24 is stable.

[0085] In some possible implementations, the cantilever beam formwork, the main beam formwork 2502, and the secondary beam formwork 2503 all include a base plate 251 and portions 252 located on both sides of the base plate 251 along its width. The base plate 251 and the side plates 252 enclose a casting cavity, which is filled with concrete. After casting, the cantilever beam, main beam, and secondary beam are formed. The formwork does not require a supporting structure, and the formwork does not need to be dismantled later, which can greatly reduce labor and time costs during construction.

[0086] In some possible implementations, the precast floor slab 3 includes a bottom slab 31 and truss reinforcement 32 disposed on the bottom slab 31. The bottom slab 31 is laid on the wall-column-beam structure, and the floor slab concrete is poured directly onto the bottom slab 31, covering the truss reinforcement 32.

[0087] The bottom plate 31 is a cement floor slab or a color steel plate. The truss reinforcement 32 is directly welded to the bottom plate 31, and the precast floor slab 3 is directly laid on the wall column beam structure for pouring.

[0088] In some possible implementations, the exterior wall panel 11 includes a foamed cement insulation layer b and an ultra-high performance concrete layer c, wherein the ultra-high performance concrete layer c is disposed on both sides of the foamed cement insulation layer b along the thickness direction, and a steel mesh a is disposed between the ultra-high performance concrete layer c and the foamed cement insulation layer b.

[0089] Foamed cement insulation layer (b) provides thermal insulation. It uses foamed cement insulation boards with low thermal conductivity, effectively preventing heat transfer. In summer, it blocks high outdoor temperatures from entering the room, and in winter, it reduces heat loss, maintaining a stable room temperature. Furthermore, it is fireproof and waterproof; the material itself is non-combustible and has good waterproof performance, making it suitable for use as a firebreak and meeting building fire safety requirements. Additionally, it reduces the load on walls; its low density allows for thinner walls, increasing usable indoor space and avoiding the heaviness of traditional brick walls.

[0090] Steel mesh A serves as a reinforcement structure. Embedding steel mesh A into the wall enhances tensile strength and load-bearing capacity, preventing deformation. It can also reduce the risk of cracking by constraining the differences in thermal expansion and contraction between different materials.

[0091] The ultra-high performance concrete layer (C) uses UHPC (ultra-high performance concrete), which boasts high strength, with a compressive strength exceeding 120 MPa, far surpassing ordinary concrete, and can withstand extreme loads. It exhibits strong durability, is impermeable, corrosion-resistant, and wear-resistant, making it suitable for extreme environments and offering a long service life.

[0092] The partition wall panel 12 includes a foamed cement insulation layer b and a crack-resistant mortar cement layer d. The crack-resistant mortar cement layer d is disposed on both sides of the foamed cement insulation layer b along the thickness direction. A fiberglass mesh cloth e is disposed between the crack-resistant mortar cement layer d and the foamed cement insulation layer b.

[0093] The crack-resistant mortar cement layer (d) has good crack resistance. By applying two coats of mortar and embedding fiberglass mesh (e), the wall surface toughness is enhanced, preventing cracking. It also has strong adhesion, improving the bond strength between the mortar and the substrate, ensuring structural stability.

[0094] Fiberglass mesh fabric is crack-resistant and waterproof, preventing crack propagation, enhancing impermeability, extending wall life, providing corrosion and fire resistance, resisting chemical corrosion and high temperatures, and improving building durability. It is also lightweight yet high-strength, easy to install and reduces load pressure.

[0095] The door and window wall panel 13 includes a foamed cement insulation layer b and an ultra-high performance concrete layer c. The ultra-high performance concrete layer c is disposed on both sides of the foamed cement insulation layer b along its thickness direction. A steel mesh a is disposed between the ultra-high performance concrete layer c and the foamed cement insulation layer b. The door and window wall panel 13 has a window 1301. The door and window wall panel 13 is a type of exterior wall and needs to achieve similar performance; therefore, its structure is similar to that of the exterior wall panel 11.

[0096] Furthermore, the door and window wall panel 13 includes a main board 131 and an extension board 132. The window 1301 is disposed on the main board 131, and the extension board 132 forms half of the door opening 1302 on the main board 131. The two door and window wall panels 13 are spliced ​​together to form the entire door opening 1302.

[0097] The preferred embodiments disclosed above are merely illustrative of this application. The preferred embodiments do not exhaustively describe modifications and variations. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
