[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1

[0035] As Figures 1-9As shown in the figure, an embodiment of the present utility model provides a heat-insulating building component, which has a hierarchical structure and includes two panels and a heat-insulating board 100 sandwiched between the two panels. A plurality of U-shaped members 300 are provided at each edge of the heat-insulating board 100. The U-shaped members 300 are buckled on the corresponding edges of the heat-insulating board 100, and each edge of the panel is fixedly connected to the U-shaped member 300 on the corresponding edge of the heat-insulating board 100 through a threaded fastener.

[0036] In one embodiment, as Figure 1 , a plurality of embedding grooves are provided at each edge of the heat-insulating board 100, and each of the U-shaped members 300 is correspondingly embedded in each of the embedding grooves. The embedding grooves are recessed at the edges of the heat-insulating board 100. After the U-shaped members 300 are embedded, preferably, the surface of the U-shaped members 300 is coplanar with the surface of the heat-insulating board 100, so that the panel can be fitted and connected to the heat-insulating board 100. In addition, the embedding grooves can play a certain limiting and constraining role on the U-shaped members 300, improving the integral combination of the panel and the heat-insulating board 100.

[0037] The above-mentioned U-shaped member 300 includes two parallel clamping plates and a connecting plate connecting the two clamping plates. Among them, the plate surfaces of the two clamping plates are parallel to the plate surface of the heat-insulating board 100, and the two clamping plates are respectively abutted against the two side plate surfaces of the heat-insulating board 100, and the connecting plate is abutted against the end surface of the corresponding edge of the heat-insulating board 100 (the top surface / bottom surface / two side surfaces of the heat-insulating board 100), realizing the buckling of the U-shaped member 300 on the corresponding edge of the heat-insulating board 100.

[0038] Further, after the U-shaped member 300 is buckled on the heat-insulating board 100, one or more bolts pass through the two clamping plates and are locked by nuts, which can ensure the connection reliability between the U-shaped member 300 and the heat-insulating board 100, prevent the U-shaped member 300 from separating from the heat-insulating board 100, and in particular, can improve the cooperative stress-bearing performance of the two clamping plates, and further improve the cooperative stress-bearing performance of the two side panels. Among them, the bolt connection position is preferably located at the end of the clamping plate, that is, on the side far from the connecting plate, so that the connecting bolts can avoid the frame-shaped plate 200.

[0039] Preferably, a steel wire mesh skeleton is provided in the above-mentioned heat-insulating board 100, which can improve the structural strength and stiffness of the heat-insulating board 100; in particular, the structural strength and stress-bearing performance of the edges of the heat-insulating board 100 can be improved by increasing the steel wire density at each edge of the heat-insulating board 100, so as to ensure the connection reliability with the U-shaped member 300 and the panel, and prevent defects such as cracking due to stress at the edges of the heat-insulating board 100.

[0040] The above-mentioned U-shaped member 300 can be a steel component or can be made of building composite materials. Further, stiffening ribs can be provided on the U-shaped member 300 to play roles such as increasing the structural strength and stress-bearing performance.

[0041] like Figure 1 and Figure 4 A hollow groove may be provided on the U-shaped member 300 to reduce the weight of the insulation board 100 and the building components.

[0042] In this embodiment, the U-shaped piece 300 is buckled on the edge of the insulation board 100, and the U-shaped piece 300 is fastened to the panels on both sides, so that the panels on both sides are connected as a whole and bear force in coordination, while ensuring the overall structural strength and other properties of the building component, the insulation board 100 and the panels are assembled at the same time, thereby facilitating the construction of the insulation layer in the building component and ensuring the insulation performance of the building component and the prefabricated building. The panels on both sides are completely separated by the insulation board 100, which reliably solves the problem of handling cold and hot bridges in the building component.

[0043] In one embodiment, if Figures 2-10 At least one of the panels is a frame-type panel 200, and each frame plate 201 of the frame-type panel 200 is fastened to the U-shaped member 300 on the corresponding edge of the insulation board 100. The frame-type panel 200 is used to ensure the structural strength and rigidity of the building component, which is not only convenient for connection with the insulation board 100 / U-shaped member 300, but also convenient for installing decorative panels and / or water and electricity pipes.

[0044] In one embodiment, if Figures 2-7 At least part of the frame plate 201 includes a first plate body 2011 and a second plate body 2012 vertically connected, the first plate body 2011 is in contact with the insulation board 100 and is fastened to the corresponding U-shaped member 300 through threaded fasteners, and the second plate body 2012 is located on the side of the first plate body 2011 away from the insulation board 100.

[0045] Optionally, at least part of the frame plate 201 is an L-shaped frame plate, and the end of the second plate body 2012 is connected to the end of the first plate body 2011, and the L-shaped frame plate can be made of angle steel. The frame plate 200 is preferably an integral structure, for example, four angle steels can be welded to form a frame structure, and of course, an integrally formed structure can also be used.

[0046] Among them, optionally, at least part of the frame plate 201 is a T-shaped frame plate, and the end of the first plate body 2011 can be connected to the middle of the second plate body 2012. In this case, the second plate body 2012 can be used to close the edges of the building component / the insulation board 100 to further improve the structural strength and stress-bearing performance of the building component; the end of the second plate body 2012 can also be connected to the middle of the first plate body 2011.

[0047] Optionally, at least part of the border plate 201 is a cross-shaped border plate. For example, the middle of its first plate body 2011 is connected to the middle of its second plate body 2012, so it combines the functions of the above two T-shaped border plates.

[0048] In another embodiment, as Figures 8-9 , each of the border plates 201 is at least partially a rectangular pipe 202, and one side of the rectangular pipe 202 abuts against the heat preservation plate 100. Among them, the above-mentioned rectangular pipe 202 includes but is not limited to a steel pipe.

[0049] Wherein, the rectangular pipe 202 includes oppositely arranged installation side wall plates and wall side wall plates, and oppositely arranged outer edge side wall plates and inner edge side wall plates. The installation side wall plate abuts against the heat preservation plate 100; the threaded fastener sequentially passes through the wall side wall plate and the installation side wall plate and then is fixedly connected to the corresponding U-shaped member 300; and / or, connection wing plates are respectively formed on two parallel clamping plates of the U-shaped member 300, and the connection wing plates abut against the corresponding inner edge side wall plates and are fixedly connected to each other through the threaded fasteners.

[0050] The above-mentioned threaded fastener is preferably a self-tapping screw, but it is also a feasible solution to use a bolt and connect two opposite border plates 201 on both sides of the heat preservation plate 100 as a whole through the bolt.

[0051] In one of the embodiments, as Figures 1-5 、 Figures 8-10 , the heat preservation type building component provided in this embodiment is a wall panel component 1, and the heat preservation plate 100 correspondingly has four edges.

[0052] In another embodiment, as Figure 6 and Figure 7 , the heat preservation type building component provided in this embodiment is a column component 2, including but not limited to an L-shaped column, a T-shaped column or a cross-shaped column. The heat preservation plate 100 is correspondingly L-shaped, T-shaped or cross-shaped, and the frame plate 200 is designed in a matching manner.

[0053] Based on the setting of the frame plate 200, a cavity can be formed on both sides of the heat preservation plate 100 respectively, and this cavity can be used for installing decorative plates and / or installing water and electricity pipelines, etc. Therefore, preferably, as Figure 4 , at least part of the border plate 201 is provided with a pipeline hole 2031 for the decoration pipeline to pass through.

[0054] In addition, as Figure 4 , at least part of the border plate 201 is provided with an assembly hole 2032 for assembling and connecting with other building components. The assembly connection between building components is preferably through bolt assembly.

[0055] Further preferably, asFigure 3 , Figures 8-10 , a support structure is provided on at least one side of the heat preservation board 100. The support structure is fixedly connected to the U-shaped members 300 on the two vertical edges of the heat preservation board 100 respectively. Setting the support structure can effectively improve the overall structural strength and stability of building components, and this method is particularly applicable to the wall panel component 1.

[0056] In one embodiment, as Figure 3 , Figures 8-10 , the support structure includes an X-shaped support member 400 or a plurality of X-shaped support members 400 distributed vertically in sequence. The four end parts of the X-shaped support member 400 are respectively fixedly connected to the four U-shaped members 300 on the two vertical edges of the heat preservation board 100 in one-to-one correspondence.

[0057] Among them, the support structure and the U-shaped member 300 can adopt a bolt fixed connection form. In particular, in the above structure of "passing one or more bolts through two clamping plates and locking them with nuts", the bolts can pass through the support structure on one side, the clamping plate on one side, the heat preservation board 100, the clamping plate on the other side and the support structure on the other side in sequence, and then be locked with nuts. In this way, not only the connection between the support structure and the U-shaped member 300 is realized, but also the support structures on both sides are stressed together, further improving the overall structural strength and mechanical properties of building components.

[0058] In one embodiment, as Figure 5 and Figure 9 , at least one of the frame-shaped plates 200 is provided with a strengthening bridge 500. The strengthening bridge 500 is fixedly connected to the two opposite frame plates 201 of the corresponding frame-shaped plate 200 respectively. For example, the vertical strengthening bridge 500 is fixedly connected to the top and bottom frame plates of the corresponding frame-shaped plate 200 respectively, and / or the horizontal strengthening bridge 500 is fixedly connected to the two side frame plates of the corresponding frame-shaped plate 200 respectively. The above strengthening bridge 500 can adopt an L-shaped strengthening plate / T-shaped strengthening plate; the strengthening bridge 500 and the frame plate 201 are preferably welded and fixed. The setting of the strengthening bridge 500 can effectively improve the structural strength, stiffness and mechanical properties of the above heat preservation type building components, and this scheme is particularly applicable to the situation where the building components are relatively wide (such as large-format wall panels) or relatively high.

[0059] When a strengthening bridge 500 and a support structure are provided at the same time, a support member 400 can be provided on each side of the strengthening bridge 500 or a plurality of support members 400 distributed vertically in sequence. The support member 400 can be an X-shaped support member 400 or a V-shaped support member 400. Among them, the two ends of the X-shaped support member 400 are fixedly connected to two U-shaped members 300 on the vertical edges of the insulation board 100 in a one-to-one correspondence, and the other two ends are fixedly connected to the strengthening bridge 500; the two ends of the V-shaped support member 400 are fixedly connected to two U-shaped members 300 on the vertical edges of the insulation board 100 in a one-to-one correspondence, and the corner ends are fixedly connected to the strengthening bridge 500.

[0060] In one embodiment, for the case where the heat-insulating building component is the column component 2, such as Figure 5 and Figure 9 , it is preferably to provide an L-shaped intermediate bridge 600 at the turning point. The L-shaped intermediate bridge 600 is fixedly connected to the upper and lower two side frame plates of the corresponding frame-shaped plate 200 respectively; among them, the L-shaped intermediate bridge 600 can be made of angle steel, and it is preferably to use welding to fix between the intermediate bridge 600 and the side frame plate. The setting of the intermediate bridge 600 can effectively improve the structural strength, stiffness and mechanical properties of the above-mentioned column component 2, and can also ensure the installation structural stability and reliability of the insulation board 100.

[0061] In one embodiment, for the case where the heat-insulating building component is the wallboard component 1, such as Figure 12 and Figure 13 , at least one side edge of the wallboard component 1 is a column node side edge. For the column node side edge, two side frame plates at the corresponding side edge respectively extend outward to form wedge-shaped node plates 204. The wedge-shaped node plates 204 taper outward and the wedge surfaces face outward. The wedge-shaped node plates 204 are provided with assembly parts for assembling and connecting with adjacent wallboards. The assembly parts are preferably bolt holes.

[0062] Among them, the two wedge surfaces at the column node side edge are perpendicular to each other, which can further facilitate the assembly of corner nodes such as L-shaped corner nodes, T-shaped corner nodes, and cross-shaped corner nodes. Specifically, two column node side edges can be assembled into an L-shaped corner node, three column node side edges can be assembled into a T-shaped corner node, and four column node side edges can be assembled into a cross-shaped corner node. Correspondingly, the included angle between the wedge surface and the thickness direction of the wallboard component 1 is 45°.

[0063] Embodiment 2

[0064] The embodiment of the present utility model provides a prefabricated building, including:

[0065] A plurality of prefabricated wallboards 1, at least part of the prefabricated wallboards 1 adopt the heat-insulating building components provided in the above-mentioned Embodiment 1, and the heat-insulating building components are designed into corresponding structures;

[0066] And / or, including at least one precast column 2, at least part of the precast column 2 adopts the heat-insulating building component provided in the first embodiment above, and the heat-insulating building component is designed into a corresponding structure.

[0067] In another embodiment, such as Figure 10 and Figure 11 , a precast column 2 is provided: the precast column 2 includes a column top plate 22, a column bottom plate 23 and a plurality of vertical pipes 21. The vertical pipes 21 are arranged at intervals to form a column frame. The column top plate 22 is connected to the top end of the column frame, and the column bottom plate 23 is connected to the bottom end of the column frame. When the precast wall panel 1 of the heat-insulating building component type is adopted, the side border plates of the frame-shaped plate 200 are fixedly connected to the vertical pipes 21 at the corresponding edge parts of the above-mentioned precast column 2, including but not limited to being fixed by bolts / sheet metal screws, etc. Among them, a plurality of transverse connecting pipes 24 arranged in sequence from top to bottom can be adopted to connect between adjacent vertical pipes 21, which can significantly improve the structural strength, stiffness and mechanical properties of the precast column 2.

[0068] In another embodiment, such as Figure 13 , each precast wall panel 1 at the intersection of longitudinal and transverse walls adopts the wall panel component 1 with a column node edge provided in the first embodiment above. At the intersection of longitudinal and transverse walls, the column node edges of each wall panel component 1 are assembled and connected to form a column-free corner node.

[0069] Among them, at the intersection of longitudinal and transverse walls, two precast wall panels 1 can be assembled into an L-shaped intersection node, and the L-shaped column at this node can be cancelled; at the intersection of longitudinal and transverse walls, three precast wall panels 1 can be assembled into a T-shaped intersection node, and the T-shaped column at this node can be cancelled; at the intersection of longitudinal and transverse walls, four precast wall panels 1 can be assembled into a cross-shaped intersection node, and the cross-shaped column at this node can be cancelled.

[0070] Based on the above scheme, a column-free prefabricated building can be realized, with a simple structure and ingenious form. While ensuring the building quality, it reduces the number of components during assembly construction, and improves the standardization production level and construction efficiency of wall prefabrication construction.

[0071] Furthermore, such as Figure 13 , at the above-mentioned column-free corner node, each column node edge encloses a node cavity 10, and concrete is poured in the node cavity 10 to form a steel-concrete structural node, which can further improve the structural strength and mechanical properties of the column-free corner node, as well as improve the seismic resistance of the prefabricated building; moreover, each column node edge can form a formwork, so the in-situ concrete construction is very convenient and can obtain high construction quality and construction efficiency.

[0072] In the above structure, the concrete in the node cavity 10 can not only improve the structural integrity and cooperative force-bearing capacity of the edges of each column node, but also solve the cold and heat bridge problems at the intersections of longitudinal and transverse walls.

[0073] In a further optional embodiment, the wedge-shaped node plate 204 is a hollow plate, and a top pouring hole is opened at the top of the wedge-shaped node plate 204. When pouring concrete into the node cavity 10, concrete is poured into the wedge-shaped node plate 204 at the same time; and / or, side pouring holes communicating with the node cavity 10 are opened on the side of the wedge-shaped node plate 204. When pouring concrete into the node cavity 10, the concrete enters the hollow cavity of the wedge-shaped node plate 204 together. This structure can further improve the bonding property between the steel structure and the concrete structure at the columnless corner node, and improve the structural strength and force-bearing performance at the columnless corner node.

[0074] In addition, for the edge of each column node, a plurality of connecting rods are used to connect the two wedge-shaped node plates 204 at the edge of the column node. This can not only improve the structural integrity and cooperative force-bearing capacity of the two side frame plates 200, but also effectively improve the bonding property between the concrete and the wedge-shaped node plate 204, thereby improving the structural strength and force-bearing performance at the columnless corner node and the overall quality of the prefabricated building.

[0075] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
