Description

Technical Field

[0001] The invention relates to the technical field of building prefabricated structures, in particular to a prefabricated board structure used for buildings. Background Art

[0002] The floor slab is a load-bearing structural slab used to bear horizontal loads in construction projects. The current conventional practice is to use cast-in-place concrete or truss composite slabs, that is, to support the formwork or support the truss slab, tie the steel bars, and then cast the concrete on site. After the concrete reaches the strength, the formwork is removed to make it a load-bearing slab for the building. This practice requires a large amount of on-site operation, a long construction period, high difficulty, affects the environment, is prone to accidents, and is difficult to ensure the quality of the project, which is inconsistent with the current requirements for prefabricated development. The non-load-bearing walls of buildings, especially the non-load-bearing partition walls and external maintenance walls of residential buildings, are still built with traditional blocks, which is also an urgent problem to be solved in the current development of prefabricated buildings to improve the assembly ratio.

[0003] In the prior art, prefabricated floor panels and prefabricated wall panels, as important components of building assembly, have the advantages of factory production, fast construction speed, convenient on-site installation, low comprehensive cost, and good quality of prefabricated panels themselves; however, after the floor panels are installed, cracks between the panels are easily generated due to temperature differences and loads, and the prefabricated floor panels are not firmly supported at the supporting ends, resulting in insufficient safety and affecting the safe use and use functions of the building, especially when an earthquake occurs, reducing the seismic resistance of the building. The cracks between prefabricated wall panels, which are also formed due to temperature changes and other factors, have troubled the construction industry for many years.

The stress connecting holes of the strain body 101 of the first type of main plate 107 and the second type of main plate 108 are inserted in sequence, so that the stress fixing part 201 abuts against the strain body 101 in the groove 102 of the first type of main plate 107, and the other end of the stress rod 202 extends out of the strain body 101 of the second type of main plate 108. The stress applying part 203 is connected to the end of the stress rod 202 extending out of the stress connecting hole of the second type of main plate 108, and the stress applying part 203 abuts against the strain body 101 in the groove 102 of the second type of main plate 108, so that multiple adjacent main plates 100 are connected to form a whole.

[0078] In this embodiment, a type of main body panel 107 has grooves 102 on both sides, a type of main body panel 108 has a groove 102 on one side and a protrusion 109 on the other side, and any two adjacent type-two main body panels 108 are matched with each other through the grooves 102 and the protrusions 109.

[0080] In this embodiment, the use of a combined prefabricated panel structure can alleviate various problems of existing cast-in-place floor panels, solve the problem of unstable support of traditional prefabricated floor panels, and effectively improve the earthquake resistance. At the same time, due to the stress applied during installation between the main panels 100, the cracks between the single main panels 100 that have not been solved for a long time are completely solved, and the problem of the aesthetics of the use of prefabricated floor panels and prefabricated wall panels is solved; and through factory production, the comprehensive cost is reduced, labor is saved, and the production environment of workers is improved. The horizontal structure and partition wall structure are completed at one time, which reduces the self-weight and load weight of the building. It has obvious cost advantages and efficiency advantages over the truss panels in existing prefabricated buildings. At the same time, the prefabricated panel structure can be used for concrete frame structures, concrete frame shear wall structures, steel structures and steel tube concrete structures, etc., and has wide applicability and broad social and economic benefits.

[0081] In a preferred embodiment of the present invention, the gap between the two main body plates 100 and the connecting member 200 is filled with a filling part.

[0082] In this embodiment, after the two main body panels 100 are fixedly connected by using the strain bodies 101 and the connectors 200 , it is necessary to fill the gap between the two main body panels 100 with a cementitious material.

[0083] In a preferred embodiment of the present invention, a wing edge 110 is provided at one end of one side edge of the main plate 100, and any two adjacent main plates 100 are connected by the wing edge 110; or, wing edges 110 are provided at both ends of one side edge of the main plate 100, and any two adjacent main plates 100 are connected by the wing edge 110.

[0084] Since the main panels 100 need to be connected by a butt-lock connection, according to different connection and casting methods of the main panels 100, wing edges 110 can be respectively provided at both ends of the edge of one long side of the main panel 100, or a wing edge 110 can be respectively provided at one end of the edge of one long side of the main panel 100, and a gap groove 102 can be opened at the other end, so as to facilitate pouring and filling.

[0085] like Figure 12-16As shown, optionally, stress connection can be performed between main panels 100 with different structures through a formless and ribbed cast-in-place connecting belt structure, wherein, in a preferred embodiment of the present invention, the strain body 101 includes connecting ribs; the connecting member 200 includes fixed ribs and a first filling portion 205; one end of the connecting rib is pre-buried in the main panel 100, and the other end of the connecting rib extends out of the main panel 100; any two adjacent main panels 100 are overlapped by the connecting ribs, the fixed ribs are used to be wound around the outside of the connecting ribs between the two adjacent main panels 100, and the first filling portion 205 is used to fill the outside of the connecting ribs of any two adjacent main panels 100, so that multiple main panels 100 are connected to form a whole.

[0086] Optionally, the structure of the main panel 100 can be in various forms; for example: the lower end edges of both sides of the main panel 100 in the long side direction are provided with protruding wing edges 110, and the wing edges 110 serve as the required template for the cast-in-place connecting strip. The wing edges 110 at the intersection of adjacent main panels 100 are in a parent-child relationship with each other. Several exposed circular connecting ribs are pre-buried on both sides of the main panel 100 along the long side direction, and the connecting ribs are located at the upper part of the plate wing edges 110. After the adjacent main panels 100 are installed in place, the circular connecting ribs of the adjacent main panels 100 overlap each other, the overlapping method is firm, and the overlapping length meets the requirements of the specification; the lower wing edges 110 of the two adjacent main panels 100 and the side surfaces of the main panels 100 form a groove 102.

[0087] For example, the edges of the upper and lower ends of the long sides of the main plate 100 are provided with protruding wing edges 110, which are used as the required templates for the cast-in-place connection belts. The wing edges 110 at the intersection of adjacent main plates 100 are in a parent-child relationship with each other, and the wing edges 110 of the long sides of the main plate 100 are provided with a plurality of transverse grooves 102, each of which forms a notch at only one of the upper and lower edges, serving as a connection rib connection operation hole; the two sides of the main plate 100 are provided with a notch at the upper and lower edges. Several exposed circular connecting ribs are pre-buried, and the connecting ribs are located inside the plate thickness and between the upper and lower wing edges 110. After the adjacent main panels 100 are installed in place, the circular connecting ribs of the adjacent main panels 100 overlap each other, and the overlapping length meets the requirements of the specification. The upper and lower wing edges 110 of the two adjacent main panels 100 and the sides of the main panels 100 form a "column barrel" shape, and a gap is left in the wing edge 110 at the upper end of the main panel 100, through which the cementitious material can be filled for pouring.

[0088] In this embodiment, the first filling part 205 can be cast from the upper part of the connection belt, and the cementitious material of the cast-in-place connection belt will not form leakage at the fitting part of the wing edge 110. When the cementitious material of the connection belt solidifies and reaches strength, the strength of the connection belt exceeds the corresponding cross-sectional strength of the main plate 100 itself, forming an integral prefabricated plate structure; the fixed connection belt formed by the connection ribs and cementitious material between the two main plates 100 solidifies the two main plates 100 together. When the main plates 100 are deformed, the connection ribs bear the tensile force, and the first filling part 205 bears the expansion pressure. Because the connection strength of the connection belt is greater than the corresponding cross-sectional strength of the plate itself, cracks will not occur at the junction of the two main plates 100. Thus, the problem of cracks caused by temperature changes is successfully solved.

[0089] like Fig.15 and Fig.16 As shown, on the basis of the above embodiment, further, the connection method of the connecting member 200 provided in this embodiment and the main body plate 100 can be multiple ways. In a preferred embodiment of the present invention, the main body plate 100 includes a third type of main body plate 111 and a fourth type of main body plate 112; a strain body 101 is provided on the third type of main body plate 111, and the strain body 101 includes a connecting rib; the connecting member 200 includes a second filling portion 206 and a third filling portion 207; one end of the connecting rib is pre-buried in the third type of main body plate 111, and the other end of the connecting rib extends out of the third type of main body plate 111; the fourth type of main body plate 112 is provided with a strain body 101, and the strain body 101 includes a connecting rib; the connecting member 200 includes a second filling portion 206 and a third filling portion 207; one end of the connecting rib is pre-buried in the third type of main body plate 111, and the other end of the connecting rib extends out of the third type of main body plate 111; A plug hole 113 is provided on one side of the corresponding type-3 main body plate 111, and the connecting rib is used to be inserted into the plug hole 113. A filling groove 114 is provided on the type-4 main body plate 112, and the filling groove 114 is extended in a direction perpendicular to the plug hole 113. The second filling portion 206 is used to fill the filling groove 114 to fix the connecting rib inserted in the plug hole 113 in the type-4 main body plate 112; the third filling portion 207 is used to fill the gap between any two adjacent type-3 main body plates 111 and type-4 main body plates 112, so that multiple main body plates 100 are connected to form a whole.

[0090] Optionally, protruding wing edges 110 are provided on the upper and lower end edges of the long sides of both sides of the main plate 100, and the wing edges 110 serve as the required templates for the cast-in-place connecting strips. The wing edges 110 at the intersection of adjacent main plates 100 are in a parent-child relationship with each other, and a number of transverse grooves 102 are provided on the wing edges 110 of the long sides of both sides of the main plate 100, and each transverse groove 102 forms a notch as a material inlet at only one of the upper and lower edges; a number of exposed circular connecting ribs are pre-embedded along the long side direction on one side of the main plate 100, and the connecting ribs are located inside the plate thickness and between the upper and lower wing edges 110, and a filling groove 114 with the same length as the main plate 100 is reserved on the other side of the main plate 100 close to the main body side wall along the long direction of the main plate 100, and a socket 113 for the circular connecting rib to pass through is reserved on the side wall shared by the filling groove 114 and the main plate 100 at a position corresponding to the reserved circular rib. After the adjacent main panels 100 are installed in place, the circular connecting ribs of the adjacent main panels 100 penetrate into the reserved filling grooves 114 by a sufficient length through the reserved insertion holes 113, and gaps are left in the gaps at the upper end wing edges 110 of the main panels 100 and in the filling grooves 114 as material openings, which can be used to fill the second filling portion 206 and the third filling portion 207 respectively.

[0091] In this embodiment, when the connecting ribs are solidified with the second filling part 206 and the third filling part 207 to reach the strength, double columns with connecting ribs are formed. The filling groove 114 ensures the anchoring of the connecting ribs on the side of the main plate 100 without ribs. The strength of the connecting belt exceeds the corresponding cross-sectional strength of the main plate 100 itself, forming an integral prefabricated plate structure. The double column connecting belt between the two main plates 100, which contains connecting ribs and the second filling part 206 and the third filling part 207, solidifies the two main plates 100 together. When the main plate 100 is deformed by temperature, the connecting ribs bear the tensile force, and the second filling part and the third filling part 207 bear the pressure generated by the expansion. Since the connection strength of the connecting belt is greater than the corresponding cross-sectional strength of the main plate 100 itself, cracks will not occur at the junction of the two main plates 100. Thus, the problem of cracks formed by temperature changes is successfully solved.

[0092] Optionally, the first filling part 205 , the second filling part 206 and the third filling part 207 may be made of cementitious materials or poured with concrete materials.

[0098] In this embodiment, pipe holes for passing water and electricity pipelines are reserved in the main plate 100, and thermal insulation and sound insulation materials can be placed in the pipe holes, and thermal insulation materials are filled inside the hollow plate, thereby effectively improving the thermal insulation performance of the house and improving the quality of the building. The prefabricated board is fundamentally different from the traditional prefabricated board. It realizes the transformation from the production of a single prefabricated board in the factory to the installation and assembly to become an integral prefabricated board. In terms of construction, the comprehensive cost is low. It is an important improvement on the composite panels widely used in current prefabricated buildings, and is of great significance to the re-promotion of the application of prefabricated panels and the promotion of the development of building assembly.

[0099] It should be noted that the connector 200 provided in this embodiment can be divided into a main plate 100 stress connector 200 and a main plate 100 moldless ribbed cast-in-place connecting belt structure; the main plate 100 stress connector 200 can include the main plate 100 and the stress connector 200, and the main plate 100 generates mutual stress between any two adjacent main plates 100 and connects them to form a whole through the strain body 101 and the connector 200; the stress is applied by the connector 200 to the corresponding variant 101, so that each single main plate 100 is closely connected together, and a lasting mutual stress is generated between the main plates 100 to form an integral prefabricated plate, and the lasting mutual stress between the main plates 100 effectively offsets the temperature. stress and other stresses, thereby avoiding the generation of temperature cracks between the main panels 100; the main panel 100 moldless ribbed cast-in-place connecting belt structure includes the main panel 100 and the cast-in-place connecting belt, the main panel 100 is pre-embedded with connecting ribs required for the connecting belt, and the edge of the main panel 100 is provided with a wing edge 110 that acts as a template for the cast-in-place connecting belt.

When the cementitious material solidifies and reaches strength, a cast-in-place connecting belt containing connecting ribs is formed, and the connecting belt connects the two adjacent main panels 100 to form an integral prefabricated panel structure. Since the cast-in-place connecting belt contains connecting ribs and the strength of the connecting belt exceeds the strength of the main body with the same cross section, it is ensured that cracks caused by temperature stress changes and other stresses will not be generated at the connection of the main panel 100.

[0100] Among them, the main panels 100 of the two connection methods have support members fixed to the supports of the main panels 100 at the support ends, which can effectively and firmly connect the main panels 100 and the supports, greatly enhancing the connection force between the prefabricated main panels 100 and the supports.
