DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] Combine the following Figures 1 to 12 , describing an embodiment of the present invention.

[0029] According to an embodiment of the present invention, on the one hand, a combination 1 is provided, which is a prefabricated component for installation at a window 20 of a wall. The combination 1 includes a steel frame 11 and at least two autoclaved aerated concrete panels 12. Specifically, the steel frame 11 includes a main frame portion 11a and a plurality of extension portions 11b. The main frame portion 11a is surrounded by a closed structure and forms a reserved opening 114. Among them, at least two extension portions 11b are fixedly connected to the top of the main frame portion 11a and are arranged at intervals to form at least one top mounting groove 115 together with the top of the main frame portion 11a. At least two extension portions 11b are fixedly connected to the bottom of the main frame portion 11a and are arranged at intervals to form at least one bottom mounting groove 116 together with the bottom of the main frame. The above-mentioned at least two autoclaved aerated concrete panels 12 are fixedly connected to the top mounting groove 115 and the bottom mounting groove 116 respectively.

[0030] In this embodiment, firstly, the assembly 1 of the present invention is a prefabricated component with a reserved opening 114, which can be directly installed at the window 20 of the wall without on-site assembly, and the installation efficiency is high; secondly, the steel frame 11 of the assembly 1 forms a structural column at the wall window 20, and the top and bottom of the steel frame 11 respectively form a top mounting groove 115 and a bottom mounting groove 116, and the autoclaved aerated concrete board 12 is installed in the top mounting groove 115 and the bottom mounting groove 116 to form a lintel at the wall window 20, thereby ensuring the structural quality at the wall window 20.

[0031] It should be noted that Figure 1 and Figure 2 In the figure, the left-right direction corresponds to the height direction of the wall, and the up-down direction corresponds to the horizontal direction of the wall. That is, when the assembly 1 is installed in the wall, Figure 2 In the embodiment, the top mounting groove 115 on the left side faces upward, and the bottom mounting groove 116 on the right side faces downward.

[0032] It is understandable that the present invention does not limit the specific setting dimensions of the steel frame 11 and the reserved opening 114. The setting dimensions of the steel frame 11 depend on the dimensions of the wall window 20, and the specific setting dimensions of the reserved opening 114 depend on the dimensions of the reserved opening 114 in the architectural design. In many design schemes, the width of the window 20 is greater than 2.4m, and the on-site assembly method has low construction efficiency and is difficult to ensure construction quality. The assembly 1 of the present application can be quickly and easily installed at a window 20 of a larger size such as a width greater than 2.4m, with high construction efficiency and easy to ensure installation quality.

[0033] Of course, the assembly 1 of the present invention can also be applied to a wall with a window 20 having a width less than or equal to 2.4 m, and the present application does not limit this.

[0034] In some embodiments, the top of the main frame portion 11a is provided with two extensions 11b to form a top mounting groove 115. Also, the bottom of the main frame portion 11a is provided with two extensions 11b to form a bottom mounting groove 116. Accordingly, two autoclaved aerated concrete panels 12 are provided, and the two autoclaved aerated concrete panels 12 are respectively fixedly connected to the top mounting groove 115 and the bottom mounting groove 116. The assembly 1 thus provided has a simple structure and is easy to process and manufacture.

[0035] In some embodiments, the top of the main frame portion 11a is provided with a plurality of extension portions 11b, and a plurality of top mounting grooves 115 are formed. Also, the bottom of the main frame portion 11a is provided with a plurality of extension portions 11b, and a plurality of bottom mounting grooves 116 are formed. Accordingly, a plurality of autoclaved aerated concrete panels 12 are provided. The number of autoclaved aerated concrete panels 12 provided should be the sum of the number of top mounting grooves 115 and bottom mounting grooves 116 provided, so that one autoclaved aerated concrete panel 12 is provided in each top mounting groove 115 and bottom mounting groove 116. In the thus configured assembly 1, autoclaved aerated concrete slabs 12 are disposed in the multiple top mounting grooves 115 of the main frame portion 11a to form a top lintel of the window 20, and the multiple extension portions 11b in the top lintel, that is, the extension portion 11b disposed at the top of the main frame portion 11a, can play a structural reinforcement role on the top of the window 20; autoclaved aerated concrete slabs 12 are disposed in the multiple bottom mounting grooves 116 of the main frame portion 11a to form a bottom lintel of the window 20, and the multiple extension portions 11b in the bottom lintel, that is, the extension portion 11b disposed at the bottom of the main frame portion 11a, can play a structural reinforcement role on the bottom of the window 20, thereby ensuring the structural quality at the window 20.

[0036] Exemplarily, the top mounting groove 115 and the bottom mounting groove 116 are both configured in a "U" shape, wherein the notch of the top mounting groove 115 faces upward, and the two adjacent extensions 11b located at the top of the main frame portion 11a are respectively formed as the two side walls of the top mounting groove 115, and the top of the main frame portion 11a is formed as the bottom wall of the top mounting groove 115. Wherein, the notch of the bottom mounting groove 116 faces downward, and the two adjacent extensions 11b located at the bottom of the main frame portion 11a are respectively formed as the two side walls of the bottom mounting groove 116, and the bottom of the main frame portion 11a is formed as the bottom wall of the bottom mounting groove 116.

[0037] It can be understood that the number of top mounting grooves 115 and bottom mounting grooves 116 depends on the number of extensions 11b, wherein the number of extensions 11b located at the top of the main frame 11a can be 2, 3, 4, 5 or other numbers, and the number of extensions 11b located at the bottom of the main frame 11a can be 2, 3, 4, 5 or other numbers, and the number of the two can be the same or different. For example, Figure 1 As shown, the extension portion 11b located at the top of the main frame portion 11a and the extension portion 11b located at the bottom of the main frame portion 11a can be set to 4, and 3 top mounting grooves 115 and 3 bottom mounting grooves 116 are formed at the top and bottom of the main frame portion 11a respectively.

[0038] Among them, the top mounting groove 115 and the bottom mounting groove 116 can be arranged opposite to each other, that is, the extension portion 11b located at the top of the main frame portion 11a and the extension portion 11b located at the bottom of the main frame portion 11a are arranged one by one; or the top mounting groove 115 and the bottom mounting groove 116 can also be staggered, that is, the extension portion 11b located at the top of the main frame portion 11a and the extension portion 11b located at the bottom of the main frame portion 11a are staggered.

[0039] Among them, along the height direction, that is, Figure 1 In the left and right directions, the extension portion 11b at the top is roughly flush with the top end of the autoclaved aerated concrete slab 12 located in the top mounting groove 115, and the extension portion 11b at the bottom protrudes from the bottom end of the autoclaved aerated concrete slab 12 located in the bottom mounting groove 116, so as to match the concrete counter-ridge 23 set on the lower structure 22.

[0040] In some embodiments, the steel frame 11 includes two cross beams 111 and two first columns 112, the two cross beams 111 are parallel and spaced along the first direction, and the two first columns 112 are parallel and spaced along the second direction; the two first columns 112 are fixedly connected to the two sides of the two cross beams 111, respectively, and the two cross beams 111 and the two first columns 112 together form the main frame portion 11a. In the first direction, the two ends of the first column 112 protrude from the two cross beams 111, respectively, and the part of the first column 112 protruding from the cross beam 111 forms the extension portion 11b.

[0041] It should be noted that the first direction is the height direction, that is, Figure 1 and Figure 2 The second direction is the horizontal direction, that is, Figure 1 and Figure 2 The up and down directions in .

[0042] In this embodiment, the cross beam 111 and the first column 112 are arranged perpendicular to each other and form a rectangular frame-shaped reserved opening 114. The upper cross beam 111 of the two cross beams 111, i.e. Figure 2 The left side crossbeam 111 forms the top of the main frame portion 11a, and the crossbeam 111 located below, i.e. Figure 2 The crossbeam 111 on the middle right side forms the bottom of the main frame portion 11a. The middle parts of the two first columns 112 form the two sides of the main frame portion 11a respectively. Along the first direction, that is, the direction from the top to the bottom of the main frame portion 11a, one end of the two first columns 112 protrudes from the upper crossbeam 111 of the two crossbeams 111 and forms two extensions 11b at the top; the other ends of the two first columns 112 protrude from the lower crossbeam 111 of the two crossbeams 111 and form two extensions 11b at the bottom.

[0043] In some embodiments, the steel frame 11 further includes a plurality of second columns 113, which are fixedly connected to the beam 111, and the second columns 113 form an extension 11b. Specifically, some of the second columns 113 are fixedly connected to the upper beam 111 of the two beams 111, and form the top extension 11b; and some of the second columns 113 are fixedly connected to the lower beam 111 of the two beams 111, and form the bottom extension 11b.

[0044] More specifically, the second column 113 is perpendicular to the beam 111 and is spaced along the second direction between the two first columns 112. In this embodiment, the portion of the first column 112 protruding from the beam 111 forms a partial extension 11b, and the second column 113 forms another partial extension 11b.

[0045] In some embodiments not shown, the two cross beams 111 and the two first columns 112 form a rectangular frame structure, and the steel frame 11 further includes a plurality of second columns 113, which are fixedly connected to the cross beams 111, and the second columns 113 form extensions 11b. That is, in this embodiment, the plurality of extensions 11b are all formed by the second columns 113.

[0046] For example, the cross beam 111 and the first column 112 may be integrally formed, or connected by welding to form an integral structure. For example, the second column 113 and the cross beam 111 may be integrally formed, or connected by welding to form an integral structure.

[0047] Exemplarily, the cross beam 111 , the first column 112 and the second column 113 may be steel square tubes, channel steels, section steels or other steel structures.

[0048] Further, in some embodiments, the autoclaved aerated concrete slab 12 and the steel frame 11 are connected at the connection node by using the first connector 13 and the first hook bolt 14. Specifically, the assembly 1 includes a plurality of first connectors 13 and a plurality of first hook bolts 14. Among them, some of the first connectors 13 are fixedly connected in the top mounting groove 115, and some of the first connectors 13 are fixedly connected in the bottom mounting groove 116. A first hook bolt 14 is penetrated in each autoclaved aerated concrete slab 12, and the first hook bolt 14 is arranged corresponding to the first connector 13, and the hook head of the first hook bolt 14 is fixedly connected to the first connector 13. Such an arrangement is convenient for ensuring the connection strength between the autoclaved aerated concrete slab 12 and the steel frame 11, thereby ensuring the structural quality of the wall.

[0049] For example, Figure 3 As shown, the autoclaved aerated concrete board 12 is arranged in the top mounting groove 115 or the bottom mounting groove 116, and the edge of the autoclaved aerated concrete board 12 is provided with a first connection hole 121, specifically, near the edge of the two side walls and the bottom wall of the top mounting groove 115 or the bottom mounting groove 116, and the first hook bolt 14 is passed through and fixed in the first connection hole 121. Correspondingly, the two side walls and the bottom wall of the top mounting groove 115 or the bottom mounting groove 116 are fixedly connected with the first connection member 13, and the position of the first connection member 13 corresponds to the position of the first hook bolt 14 in the first connection hole 121. When the autoclaved aerated concrete board 12 is installed in the top mounting groove 115 or the bottom mounting groove 116, the hook head of the first hook bolt 14 is fixedly connected to the corresponding first connection member 13, thereby realizing the fixed connection between the autoclaved aerated concrete board 12 and the steel frame 11.

[0050] like Figure 2 In the illustrated embodiment, the bottom wall of the top mounting groove 115 or the bottom mounting groove 116 is formed by the cross beam 111 , and the two side walls are formed by the first column 112 and the second column 113 , that is, the first connecting member 13 is fixedly connected to the cross beam 111 , the first column 112 and the second column 113 .

[0051] It can be understood that a plurality of first connecting members 13 are provided in each top mounting groove 115 and a plurality of bottom mounting grooves 116, and correspondingly, a plurality of first hook bolts 14 are provided on each autoclaved aerated concrete board 12. The present invention does not specifically limit the number of the first connecting members 13 and the first hook bolts 14, as long as the load requirements of the assembly 1 are met.

[0052] Exemplarily, the first connecting member 13 may be an angle steel, a T-shaped steel, etc. Exemplarily, the hook head of the first hook bolt 14 may be welded to the first connecting member 13 .

[0053] According to an embodiment of the present invention, on the other hand, a wall is further provided, comprising a structure 2 and the structure 2 as described in the above embodiment, wherein a window 20 is formed in the structure 2, and an assembly 1 is installed at the window 20 and fixedly connected to the structure 2. Since the wall of the present invention comprises the assembly 1 described in the above embodiment, it has the same technical effect as the assembly 1 of the present invention, and will not be described in detail herein.

[0054] In some embodiments, the connection nodes of the structure 2 and the assembly 1 are fixedly connected by a connection structure 3. Specifically, the wall includes a plurality of connection structures 3, and the plurality of connection structures 3 are respectively connected between the plurality of extension portions 11b and the structure 2. Figure 4 and 5 As shown, the connection structure 3 includes an anchor 31 and a second connection member 32 connected to each other. The anchor 31 is fixedly connected to the structure 2, and the second connection member 32 is fixedly connected to the extension portion 11b, thereby realizing a fixed connection between the steel frame 11 of the assembly 1 and the structure 2, facilitating construction, further improving construction efficiency, and making it easy to ensure construction quality, thereby ensuring the overall strength of the structure.

[0055] For example, Figure 6 As shown, the anchor 31 and the second connecting member 32 are fixedly connected, and both are fixedly arranged on the structure 2. The anchor 31 and the second connecting member 32 can be bolted, welded, or integrally formed. The anchor 31 can be pre-buried in the structure 2 or placed in the structure 2 later. When the assembly 1 is installed, the end of the extension portion 11b of the assembly 1 is fixedly connected to the second connecting member 32, such as by welding, to achieve the fixation of the assembly 1 and the structure 2.

[0056] For example, Figure 7 As shown, the anchor 31 and the second connector 32 are detachably connected, and the anchor 31 can be pre-buried in the structure 2 or placed in the structure 2 later, and the free end of the anchor 31 is provided with a threaded section. The second connector 32 is fixed to the bottom of the extension 11b, and the second connector 32 is provided with a connection hole corresponding to the anchor 31. The second connector 32 and the extension 11b can be welded or integrally formed. When installing the assembly 1, the anchor 31 passes through the connection hole of the second connector 32, and the second connector 32 and the anchor 31 are fixed by using a nut and the threaded section on the anchor 31, thereby fixing the assembly 1 and the structure 2.

[0057] Exemplarily, the anchor 31 may be an expansion bolt, a chemical bolt, an embedded bolt, etc. Exemplarily, the first connecting member 13 may be a steel plate, a steel block, etc.

[0058] Specifically, the structure 2 includes an upper structure 21 and a lower structure 22, and the window 20 is formed between the upper structure 21 and the lower structure 22. A plurality of the above-mentioned connection structures 3 are provided on both the upper structure 21 and the lower structure 22, and each extension portion 11b located at the top of the steel frame 11 is respectively connected to the corresponding connection structure 3 on the upper structure 21, and each extension portion 11b located at the bottom of the steel frame 11 is respectively connected to the corresponding connection structure 3 on the lower structure 22.

[0059] It can be understood that the autoclaved aerated concrete board 12 is installed in the top mounting groove 115 or the bottom mounting groove 116, and the top of the top mounting groove 115 and the bottom of the bottom mounting groove 116 are both open, that is, when the assembly 1 is installed between the upper structure 21 and the lower structure 22, the autoclaved aerated concrete board 12 located in the top mounting groove 115 is adjacent to the upper structure 21, and the lower structure 22 located in the bottom mounting groove 116 is adjacent to the lower structure 22.

[0060] In some embodiments, an adhesive layer is provided between the autoclaved aerated concrete board 12 located in the top mounting groove 115 and the upper structure 21; and an adhesive layer is provided between the autoclaved aerated concrete board 12 located in the bottom mounting groove 116 and the lower structure 22 to ensure the sealing and waterproof properties between the assembly 1 and the structure 2.

[0061] In some embodiments, a concrete counter-ridge 23 is further provided on the lower structure 22, and the concrete counter-ridge 23 is located between the autoclaved aerated concrete board 12 in the bottom installation groove 116 and the lower structure 22. In this embodiment, the adhesive layer between the autoclaved aerated concrete board 12 in the bottom installation groove 116 and the lower structure 22 is specifically provided between the autoclaved aerated concrete board 12 and the concrete counter-ridge 23.

[0062] like Figure 4 As shown, along the horizontal direction, that is Figure 4 In the vertical direction, the extension length of the concrete counter-ridge 23 is substantially the same as the length of the autoclaved aerated concrete slab 12, and a gap is reserved between adjacent concrete counter-ridges 23. The above-mentioned connection structure 3 on the lower structure 22 is located in the gap between the concrete counter-ridges 23, and at least part of the extension part 11b of the steel frame 11 located at the bottom can penetrate into the gap and realize fixed connection with the lower structure 22 through the connection structure 3 in the gap.
