Description

Technical Field

[0001] This invention belongs to the field of energy-saving building technology, and in particular relates to a firmly connected thermal insulation concrete composite slab structure for buildings. Background Technology

[0002] Prefabricated buildings have developed rapidly due to their good economic, environmental and social benefits. With the continuous improvement of building energy conservation and environmental protection requirements, the thermal insulation technology of building structures is also being strengthened. In particular, floor insulation and sound insulation technology have developed rapidly and become an important building energy conservation technology in my country. Among them, thermal insulation concrete composite slabs for buildings are a widely used energy-saving building material.

[0003] Concrete composite slabs are monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Concrete composite slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity. This construction technology saves the process of on-site formwork and some of the steel bar tying, thus improving construction efficiency.

[0004] An existing Chinese patent application with publication number CN117661769A discloses a concrete composite thermal insulation and sound insulation board, which includes a concrete composite board, a thermal insulation and sound insulation board and a junction box. The concrete composite board is connected to the thermal insulation and sound insulation board by cement. The junction box passes through the concrete composite board and is installed on the thermal insulation and sound insulation board. The gap between the junction box and the thermal insulation and sound insulation board is filled with cement.

[0005] The aforementioned composite concrete insulation and soundproofing board includes a composite concrete slab and an insulation and soundproofing board. After the two are stacked, they are connected by cement curing. This single connection method, which relies solely on cement curing, is prone to weakening of the connection between the composite concrete slab and the insulation and soundproofing board due to vibration and other factors during transportation, thereby reducing the overall connection strength of the composite concrete insulation and soundproofing board to a certain extent. Summary of the Invention

[0006] The purpose of this invention is to provide a robustly connected insulated concrete composite slab structure for buildings. Through the specific structural design of the ribbed composite component, the insulation board, connector one, and connector two, this invention solves the problem in the prior art where the single connection method relying solely on cement curing is prone to weakening of the connection force between the concrete composite slab and the insulation and sound insulation board due to vibration and other factors during transportation, thus reducing the overall connection strength of the concrete composite insulation and sound insulation slab to a certain extent.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a firmly connected thermal insulation concrete composite slab structure for buildings, including a stiffener-plate composite assembly, which is made by splicing a composite base plate and a steel reinforcement frame; a composite concrete layer, cast in place on the stiffener-plate composite assembly, forming an integral structure with the steel reinforcement frame; an insulation board, which is tightly attached to the side of the composite base plate opposite to the steel reinforcement frame, and is connected to the composite base plate through the steel reinforcement frame, with adjacent insulation boards connected by H-channel steel; the steel reinforcement frame includes a steel mesh, a first connector, and a second connector, the steel mesh being arranged in a cross pattern, the first connector being installed on the composite base plate and engaging with the steel mesh, and the first connector being used to limit the steel mesh in the Y-axis direction; the second connector penetrating the insulation board and engaging with the steel mesh, and being used to limit the steel mesh in the X-axis and Z-axis directions.

[0009] The present invention is further configured such that the surface of the laminated substrate is provided with a positioning groove and a second connection hole, the positioning groove and the second connection hole are arrayed on the surface of the laminated substrate, and the second connection hole is provided in a one-to-one correspondence with the first connection hole.

[0010] The present invention is further configured such that the reinforcing mesh is composed of a plurality of transverse reinforcing bars and longitudinal reinforcing bars, the transverse reinforcing bars and longitudinal reinforcing bars are arranged in a cross pattern, the transverse reinforcing bars are arranged above the composite substrate along the X-axis and penetrate the composite concrete layer, and the longitudinal reinforcing bars are arranged above the composite substrate along the Y-axis and penetrate the composite concrete layer.

[0011] The present invention is further configured such that the cross intersection of the transverse and longitudinal reinforcing bars is fixed by tying, or the longitudinal reinforcing bars are provided with bent sections corresponding to the transverse reinforcing bars, and the cross intersection of the transverse and longitudinal reinforcing bars is fixed by the bent sections and tying.

[0012] The present invention is further configured such that the connecting member 1 consists of a positioning head, a fixing rod, and a limiting buckle. The positioning head is tightly fitted into the corresponding positioning groove, and the positioning head and the limiting buckle are connected by the fixing rod. The limiting buckle has a reinforcing bar insertion port 1 on its peripheral side. The transverse reinforcing bar is fitted into the limiting buckle by the reinforcing bar insertion port 1. The reinforcing bar insertion ports 1 on several limiting buckles arranged along the X-axis direction face the same direction, while the reinforcing bar insertion ports 1 on two adjacent limiting buckles arranged along the Y-axis direction face opposite directions.

[0013] The present invention is further configured such that the second connector is composed of a locking part and a limiting part. The locking part includes a limiting plate that fits tightly in the mounting groove. A locking post is fixed on the limiting plate and passes through the first connecting hole and the second connecting hole in sequence. The locking post is provided with an arc-shaped cavity, and the top of the locking post is provided with a curved groove concentric with the arc-shaped cavity.

[0014] The present invention is further configured such that the limiting plate is provided with an annular isolation groove concentric with the locking post on the side of the limiting plate, and a heat preservation plate that fits tightly with the limiting plate is tightly fitted on the locking post, and an isolation heat preservation ring that fits tightly in the annular isolation groove is fixed on the surface of the heat preservation plate.

[0015] The invention is further configured such that the top of the locking post is provided with a second steel bar insertion port extending along its axial direction, the longitudinal steel bar is inserted and fitted inside the second steel bar insertion port, and an elastic pad layer that is in close contact with the longitudinal steel bar is installed at the bottom of the second steel bar insertion port. The dimension of the elastic pad layer along the axial direction of the limiting part is smaller than that of the second steel bar insertion port.

[0016] The present invention is further configured such that the limiting part is an annular structure adapted to the arc-shaped cavity, the inner diameter of the limiting part, the inner diameter of the arc-shaped cavity and the diameter of the curved groove are the same, the peripheral side of the limiting part is provided with a locking inlet with the same diameter as the locking post, and the inner wall of the limiting part is provided with a limiting groove adapted to the longitudinal reinforcing bar, the limiting groove being used to limit the longitudinal reinforcing bar in the X-axis direction.

[0017] The present invention has the following beneficial effects: 1. The present invention provides several connectors 1 and 2 on the composite substrate and the insulation board. Connector 1 is installed on the composite substrate and is connected to the reinforcing mesh. Connector 1 is used to limit the reinforcing mesh in the Y-axis direction. Connector 2 passes through the insulation board and is connected to the reinforcing mesh. It is used to limit the reinforcing mesh in the X and Z-axis directions. In this way, the connection between the reinforcing plate composite assembly, the insulation board and the composite concrete layer is greatly improved through the combined action of connector 1 and connector 2, so that the overall integrity of the insulated concrete composite slab structure after pouring is stronger.

[0018] In this invention, after the longitudinal reinforcing bars are placed inside the locking column and supported by the reinforcing bars, some concrete can be poured into the reinforcing bar placement entrance 2 along the gap between the longitudinal reinforcing bars and the reinforcing bar placement entrance 2. After the cement has cured, the longitudinal reinforcing bars can be fixed in the reinforcing bar placement entrance 2. In this way, the longitudinal reinforcing bars and the locking column can be firmly connected together to form an integral reinforced structure. Through the supporting effect of each connector 2 and connector pair on the longitudinal and transverse reinforcing bars, it can be ensured that the cross-shaped longitudinal and transverse reinforcing bars maintain a certain distance from the composite base plate, which facilitates the preparation of reinforcing mesh and improves construction efficiency.

[0019] In this invention, the diameter of the locking post is 0.5-1.0 cm smaller than the diameters of connecting hole one and connecting hole two, so as to ensure that concrete or cement can flow into the installation groove through connecting hole one and connecting hole two, and then fill the gap between connecting hole one and connecting hole two and the locking post through the cement curing effect, thereby improving the firmness of the connection between the composite substrate and the insulation board.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figures 1-12 The present invention is a firmly connected thermal insulation concrete composite slab structure for buildings, comprising a stiffener-plate composite assembly 1, a composite concrete layer 3, and an insulation board 4; the stiffener-plate composite assembly 1 is made by splicing a composite base plate 2 and a steel reinforcement frame; the composite concrete layer 3 is cast in place on the stiffener-plate composite assembly 1 and is cast into an integral structure with the steel reinforcement frame; the insulation board 4 is tightly attached to the side of the composite base plate 2 opposite to the steel reinforcement frame, and is connected to the composite base plate 2 through the steel reinforcement frame, and adjacent insulation boards 4 are connected by H-channel steel 5.

[0036] The reinforcing steel frame includes a reinforcing mesh, connector 6, and connector 7. The reinforcing mesh is arranged in a cross pattern. Connector 6 is installed on the composite base plate 2 and is snapped into the reinforcing mesh. Connector 6 is used to limit the reinforcing mesh in the Y-axis direction. Connector 7 passes through the insulation board 4 and is snapped into the reinforcing mesh. It is used to limit the reinforcing mesh in the X and Z-axis directions. In this way, the joint action of connector 6 and connector 7 greatly improves the connection strength between the reinforcing plate composite assembly 1, the insulation board 4, and the composite concrete layer 3, making the overall structure of the insulated concrete composite slab stronger after pouring.

[0037] In this embodiment of the invention, such as Figure 6As shown, the bottom of the insulation board 4 is provided with several mounting grooves 8, and the top of the insulation board 4 is provided with connecting holes 9 corresponding to the mounting grooves 8. The connecting holes 9 concentrically pass through the corresponding mounting grooves 8. One side of the insulation board 4 is provided with an adapter groove 10 extending along the length of the H-channel steel 5. The adapter groove 10 is used to keep the bottom of the insulation board 4 flush with the bottom of the H-channel steel 5, so as to improve the integrity of the structure after the H-channel steel 5 and the insulation boards 4 on both sides are spliced. The insulation board 4 can be made of professional materials with excellent thermal insulation and sound insulation effects, such as mineral wool board or polystyrene board.

[0038] In this embodiment of the invention, such as Figure 8 As shown, the surface of the composite substrate 2 is provided with positioning grooves 11 and connecting holes 12. The positioning grooves 11 and connecting holes 12 are arrayed on the surface of the composite substrate 2. The connecting holes 12 and connecting holes 9 are arranged one-to-one. That is, when the composite substrate 2 is aligned and attached to the top of the insulation board 4, each connecting hole 12 is concentrically connected to its corresponding connecting hole 9 below it, so that the connector 7 can pass through the connecting holes 12 and connecting holes 9 to complete the stable connection between the composite substrate 2 and the insulation board 4. It should be noted that the material of the composite substrate 2 can be selected according to multiple factors according to the actual construction needs. This is the prior art and will not be described in detail here.

[0039] In this embodiment of the invention, such as Figure 3 and Figure 7 As shown, the reinforcing mesh consists of several transverse reinforcing bars 13 and longitudinal reinforcing bars 14. The transverse reinforcing bars 13 and longitudinal reinforcing bars 14 are arranged in a cross pattern. The transverse reinforcing bars 13 are arranged above the composite base plate 2 along the X-axis and penetrate the composite concrete layer 3. The longitudinal reinforcing bars 14 are arranged above the composite base plate 2 along the Y-axis and penetrate the composite concrete layer 3. The reinforcing mesh structure composed of several transverse reinforcing bars 13 and longitudinal reinforcing bars 14 arranged in a cross pattern can improve the overall strength of the entire thermal insulation concrete composite slab structure after the concrete is poured (i.e., the overall strength after the reinforcing plate composite component 1 is combined with the composite concrete layer 3).

[0040] In this embodiment of the invention, such as Figure 4 and Figure 5 As shown, the cross intersection of the transverse steel bar 13 and the longitudinal steel bar 14 is fixed by tying. After the transverse steel bar 13 and the longitudinal steel bar 14 are arranged in a cross shape, the transverse steel bar 13 and the longitudinal steel bar 14 are firmly fixed by tying. In this way, the transverse steel bar 13 and the longitudinal steel bar 14 can be tied into an integrated steel mesh structure.

[0041] Alternatively, the longitudinal reinforcing bars 14 may be provided with bent sections 15 that correspond one-to-one with the transverse reinforcing bars 13. These bent sections 15 are processed using a reinforcing bar bending machine commonly used in the construction field. The cross intersection of the transverse reinforcing bars 13 and the longitudinal reinforcing bars 14 is fixed by the bent sections 15 and tie bars. The setting of the bent sections 15 can improve the firmness of the fit and binding between the transverse reinforcing bars 13 and the longitudinal reinforcing bars 14.

[0042] Example 2, based on Example 1, such as Figure 5 and Figure 9 As shown, connector 6 consists of a positioning head 16, a fixing rod 17, and a limiting buckle 18. The positioning head 16 fits tightly into the corresponding positioning groove 11. The positioning head 16 and the limiting buckle 18 are connected by the fixing rod 17. The limiting buckle 18 has a rebar insertion inlet 19 on its circumferential side. The size of the rebar insertion inlet 19 is designed to meet the insertion requirements of the transverse rebar 13. By directly inserting the positioning head 16 into the positioning groove 11 from top to bottom, the connector 6 can be quickly installed on the top of the composite substrate 2, which improves the assembly efficiency between the connector 6 and the composite substrate 2.

[0043] The transverse reinforcing bars 13 are fitted inside the limiting buckles 18 by reinforcing bar insertion ports 19. The reinforcing bar insertion ports 19 on several limiting buckles 18 arranged along the X-axis face the same direction, while the reinforcing bar insertion ports 19 on two adjacent limiting buckles 18 arranged along the Y-axis face opposite directions. Specifically, after the rapid installation of each connector 6 on the top of the composite substrate 2 is achieved, the corresponding number of transverse reinforcing bars 13 are first horizontally inserted into the limiting buckles 18 on the connector 6 through the reinforcing bar insertion ports 19. Then, the corresponding number of longitudinal reinforcing bars 14 are placed on top of the transverse reinforcing bars 13, and each bent section 15 is engaged with the transverse reinforcing bars 13 at the corresponding position. After the reinforcement is tied, the reinforcement mesh is supported and fixed on each connector 6.

[0044] Depend on Figure 5 As shown, after the steel mesh is supported and fixed on each connector 6, the steel mesh cannot move freely along the Y-axis because the steel bar insertion entrances 19 on the two adjacent limit buckles 18 arranged along the Y-axis face opposite directions. That is, each connector 6 not only supports the steel mesh, but also limits the steel mesh in the Y-axis direction.

[0045] In this embodiment of the invention, such as Figure 5 , Figure 11 and Figure 12As shown, connector 27 consists of a locking part 20 and a limiting part 21. The locking part 20 includes a limiting plate 22 that fits tightly in the mounting groove 8. A locking post 23 is fixed on the limiting plate 22, which passes through the first connecting hole 9 and the second connecting hole 12 in sequence. (It should be noted that the diameter of the locking post 23 is the same as the diameter of the first connecting hole 9 and the second connecting hole 12, or the diameter of the locking post 23 is 0.5-1.0 cm smaller than the diameter of the first connecting hole 9 and the second connecting hole 12, so as to ensure that concrete or cement can flow from the first connecting hole 9 and the second connecting hole 12 into the mounting groove 8, and then fill the gap between the first connecting hole 9 and the second connecting hole 12 and the locking post 23 through the cement curing effect, thus improving the firmness of the connection between the composite substrate 2 and the insulation board 4.) The locking post 23 is provided with an arc-shaped cavity 24, and the top of the locking post 23 is provided with a curved groove 25 concentric with the arc-shaped cavity 24.

[0046] In this embodiment of the invention, such as Figure 11 As shown, the limiting plate 22 has an annular isolation groove 26 concentric with the locking post 23 on the side of the limiting plate 22. The locking post 23 is tightly fitted with an insulation plate 27 that fits against the limiting plate 22. An isolation insulation ring 28 that fits tightly in the annular isolation groove 26 is fixed on the surface of the insulation plate 27. This ensures the tightness of the fit between the insulation plate 27 and the limiting plate 22. During the production of the thermal insulation concrete composite slab, the locking part 20 and the limiting part 21 are installed separately on the thermal insulation board 4. That is, the locking part 20 is first inserted into the thermal insulation board 4 and the composite base plate 2, and then the limiting part 21 is rotated and installed onto the locking part 20.

[0047] Furthermore, the top of the locking post 23 is provided with a second reinforcing bar insertion port 29 extending axially. The longitudinal reinforcing bar 14 is inserted into the second reinforcing bar insertion port 29. An elastic pad 30 is installed at the bottom of the second reinforcing bar insertion port 29, which is in close contact with the longitudinal reinforcing bar 14. The elastic pad 30 is smaller than the second reinforcing bar insertion port 29 in the axial direction of the limiting part 21. Through the above structural design, after the longitudinal reinforcing bar 14 is confined and supported in the second reinforcing bar insertion port 29 on the locking post 23, it can be ensured that some concrete can flow along the longitudinal reinforcing bar 14 and the second reinforcing bar insertion port 29 during concrete pouring. The gap between the two rebar insertion points 29 is entered into the two rebar insertion points 29. After the cement has cured, the longitudinal rebar 14 can be fixed in the two rebar insertion points 29. In this way, the longitudinal rebar 14 and the locking post 23 can be firmly connected together to form an integral reinforced structure. Through the support of the longitudinal rebar 14 and the transverse rebar 13 by the various connectors 2 and 16, it can be ensured that the cross-arranged longitudinal rebar 14 and transverse rebar 13 maintain a certain distance from the composite base plate 2, which facilitates the preparation of the rebar mesh for rebar tying construction and improves construction efficiency.

[0048] In this embodiment of the invention, such as Figure 10 and Figure 12As shown, the limiting part 21 is an annular structure adapted to the arc-shaped cavity 24. The inner diameter of the limiting part 21, the inner diameter of the arc-shaped cavity 24, and the diameter of the curved groove 25 are the same. The peripheral side of the limiting part 21 is provided with a locking inlet 31 with the same diameter as the locking post 23. The inner wall of the limiting part 21 is provided with a limiting groove 32 adapted to the longitudinal steel bar 14. The limiting groove 32 is used to limit the longitudinal steel bar 14 in the X-axis direction. By aligning the locking inlet 31 on the limiting part 21 downward with the locking post 23 and moving it downward along the locking post 23 until the inner wall of the limiting part 21 fits against the curved groove 25, the limiting part 21 can be inserted into the arc-shaped cavity 24 by rotating it. In this way, the insulation board 4 and the composite substrate 2 can be tightly connected.

[0049] The fabrication process for thermally insulated concrete composite slab structures in buildings is as follows: First, securely install the corresponding number of locking parts 20 through the connecting holes 9 on the insulation board 4 into each mounting slot 8. Then, place the insulation board 4 with the locking parts 20 installed flat on the construction table, ensuring that each locking part 20 is arranged vertically upwards. Next, align each connecting hole 12 on the composite substrate 2 with the locking part 20 and install it along the locking part 20 onto the top of the insulation board 4, thus achieving the initial bonding of the composite substrate 2 on the top of the insulation board 4. At this time, each locking part 20 passes through the composite substrate 2.

[0050] Subsequently, the corresponding number of connectors 6 are tightly inserted into the positioning slots 11 on the top of the composite substrate 2, and the orientation of the steel bar insertion slots 19 on each connector 6 is adjusted to meet the installation requirements. After the rapid installation of each connector 6 on the top of the composite substrate 2 is achieved, the corresponding number of transverse steel bars 13 are first horizontally inserted into the limiting buckles 18 on the connector 6 through the steel bar insertion slots 19. Then, the corresponding number of longitudinal steel bars 14 are placed on top of the transverse steel bars 13, and each bent section 15 is engaged with the transverse steel bar 13 at the corresponding position. At the same time, the longitudinal steel bars 14 are inserted into the steel bar insertion slots 29 on the top of the locking post 23 and supported by the elastic pad 30. After the reinforcement treatment, the steel mesh is supported and fixed on each connector 6.

[0051] Next, align the locking inlet 31 on the limiting part 21 downwards with the locking post 23, and move it downwards along the locking post 23 until the inner wall of the limiting part 21 is in contact with the longitudinal steel bar 14. Press the longitudinal steel bar 14 downwards to squeeze the elastic pad 30, so that the top of the longitudinal steel bar 14 is completely inserted into the steel bar insertion inlet 29. Continue to move the limiting part 21 downwards until its inner wall is in contact with the curved groove 25. Then, rotate the limiting part 21 to insert it into the arc-shaped cavity 24, and align the limiting groove 32 with the longitudinal steel bar 14 from top to bottom. After releasing the local downward pressure applied to the longitudinal steel bar 14, the elastic force of the elastic pad 30 makes the longitudinal steel bar 14 fit tightly against the groove. Pressed into the limiting groove 32, each limiting part 21 is installed and fixed on the locking post 23 in the same way. In this way, the downward extrusion force generated by each longitudinal steel bar 14 on the limiting part 21, under the tension of the locking post 23, achieves a firm connection between the insulation board 4 and the composite base plate 2, thereby improving the overall strength of the insulation concrete composite slab structure. Finally, the composite concrete layer 3 is formed by pouring concrete on the steel mesh. Thus, the building insulation concrete composite slab structure is prepared. In the future, when multiple building insulation concrete composite slab structures are spliced ​​together by using H-channel steel 5, it is only necessary to pour concrete in the space above H-channel steel 5.
