Abstract

The present invention discloses a through-type composite keel and an assembled wall. The assembled wall includes a composite keel, a wall panel, a core panel, and a wall frame. Two wall panels are parallel to each other and connected by the composite keel. Multiple composite keels are arranged side by side and vertically. The composite keel includes a vertical keel and a horizontal keel. The two vertical keels and two horizontal keels are spliced ​​into a rectangular shape. A rectangular through hole is formed between the vertical keels and the horizontal keels. The core panel extends from one side of the wall panel through the through hole to the other side of the wall panel. The wall frame is arranged around the edge of the wall panel and fixedly connects the two wall panels and the multiple composite keels. The vertical keels are not inserted in the middle of the core panel, but are arranged on both sides of the core panel and connected by the horizontal keel. Therefore, the composite keel forms a through hole along the length of the wall panel. The through hole allows the core panel to pass through, so that the core panel can be continuous in the wall panel, thereby eliminating weak points in fire protection and sound insulation.

Description

Technical Field

[0001] The present invention relates to the field of assembled walls, and in particular to a through-type combined keel and an assembled wall. Background Art

[0002] The related technologies of the assembled wall to which the subject matter disclosed in this invention relates are disclosed in:

[0003] CN115974514A Crop gypsum composite covering panel for improving fire resistance of lightweight wall and its application;

[0004] CN213418918U extra large fire door;

[0007] The defect of the above structure is that the fireproof cotton is discontinuous inside the wall panel, and the gap between the fireproof cotton and the C-shaped steel forms a fire-proof weak point. During the high-temperature burning process of the flame, the C-shaped steel will deform, causing the gap between the C-shaped steel and the fireproof cotton to expand, and the flame can pass through the gap to reach the other side of the prefabricated wall panel.

[0008] On the other hand, the sound on one side of the prefabricated wall can be transmitted to the wall panels on the other side through the wall panels and C-shaped steel, so the sound insulation and noise reduction effect of the existing prefabricated walls is not good. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figure 1As shown, the existing prefabricated wall 6 with fireproof function uses C-shaped steel 61 arranged continuously side by side as a keel. During the high-temperature burning process of the flame, the wall panel and the C-shaped steel 61 will be deformed, causing the gap between the C-shaped steel 61 and the fireproof cotton 62 to expand, and the flame can reach the other side of the prefabricated wall through the gap.

[0041] In order to solve the above technical problems, it is necessary to make the fireproof cotton between the two wall panels continuous.

[0042] This specific embodiment provides a through-type combined keel and an assembled wall. The assembled wall has continuous fireproof cotton, and the fireproof cotton can pass through the combined keel from one side of the wall panel to the other side of the wall panel.

[0043] Example 1, please refer to Figure 2 、 3 .

[0044] The combined keel includes: a vertical keel 1 and a horizontal keel 2;

[0045] The two vertical keels 1 and the two horizontal keels 2 are spliced ​​into a rectangular shape. A rectangular through hole 3 is formed between the vertical keels 1 and the horizontal keels 2 . The through hole 3 is used to pass through the core plate 5 .

[0046] Optionally, the vertical keel 1 and the horizontal keel 2 are made of C-shaped steel or channel steel, and the two are connected by welding; the core plate 5 refers to a filler similar to fireproof cotton.

[0047] The assembled wall comprises: a combined keel, a wall panel 4, a core panel 5 and a wall frame;

[0048] The two wall panels 4 are parallel to each other and connected by a composite keel. Multiple composite keels are arranged side by side and vertically. The core panel 5 extends from one side of the wall panel 4 through the through hole 3 to the other side of the wall panel 4. The wall frame is arranged around the edge of the wall panel 4 and fixedly connects the two wall panels 4 and multiple composite keels.

[0049] The wall frame is not shown in the figure. In the above embodiment, the vertical purlins 1 are arranged on both sides of the core panel 5 instead of being inserted in the middle of the core panel 5, so that the core panel 5 can be continuous in the wall panel 4, thereby eliminating the fire-proof weak points.

[0050] At the same time, since the core panel 5 is continuous, it is difficult for sound to pass through the core panel 5 through the combined keel, thereby improving the sound insulation effect.

[0051] Preferably, in embodiment 1:

[0052] Two vertical keels 1 are respectively arranged vertically on both sides of the core plate 5, and two horizontal keels 2 are respectively arranged horizontally on the upper and lower sides of the core plate 5;

[0053] The vertical purlin 1 includes a first web 11 and a first wing 12. The first wing 12 is perpendicular to the two sides of the first web 11. The two vertical purlins 1 are respectively fixedly connected to the two wall panels 4. The first webs 11 of the two vertical purlins 1 are parallel to the wall panels 4. The first wing 12 of the two vertical purlins 1 are respectively facing the other vertical purlin 1.

[0054] The transverse keel 2 includes a second web 21 and a second wing plate 22. The second wing plate 22 is vertically connected to both sides of the second web 21, and the two transverse keels 2 are respectively fixedly connected to the upper and lower ends of the two vertical keels 1. The second web 21 is horizontally arranged, and the two second wing plates 22 are respectively fixedly connected to the first webs 11 of the two vertical keels 1.

[0055] In the above embodiment, the gap between the core plate 5 and the upper and lower floor plates is equal to the thickness of the second web 21. The width of the gap is relatively small, and the fireproof weak point here can be eliminated by filling the outer side of the gap with fireproof mud.

[0056] Preferably, in order to enhance the compression and bending resistance of the vertical keel 1:

[0057] The vertical keel 1 further includes a reinforcing rib 13 . The reinforcing rib 13 is parallel to the first wing panels 12 and is disposed between the two first wing panels 12 . The reinforcing rib 13 is connected to the first web 11 by welding.

[0058] The vertical keel 1, the transverse keel 2, and the reinforcing rib 13 can be connected by the following technical means:

[0059] Option 1:

[0060] Both ends of the reinforcing rib 13 respectively abut against the two transverse keels 2 , and one end of the reinforcing rib 13 is provided with a first avoidance opening 131 for the second wing panel 22 to be inserted therein.

[0061] When the first solution is adopted, the vertical keel 1 and the horizontal keel 2 are spliced ​​into a combined keel and then transported to the construction site.

[0062] Option 2, please refer to Figure 8 :

[0063] The upper end of the reinforcing rib 13 is provided with a first avoidance opening 131 , while the lower end of the reinforcing rib 13 is not provided with the first avoidance opening 131 . The second wing plate 22 located below is provided with a third avoidance opening 221 for the end of the reinforcing rib 13 to be inserted therein.

[0064] Figure 8 The structure shown allows workers to fix the two transverse purlins 2 to the upper and lower floor slabs respectively, and then splice the vertical purlin 1 between the two transverse purlins 2.

[0065] The vertical keel 1 and the transverse keel 2 connected to the top end thereof are clamped together via the first avoidance opening 131 , and the vertical keel 1 and the transverse keel 2 connected to the bottom end thereof are connected via self-tapping screws.

[0066] When the second solution is adopted, the vertical purlin 1 and the transverse purlin 2 are transported to the construction site in the form of parts. During assembly, the upper and lower transverse purlins 2 are first fixed to the upper and lower floor slabs, and then the first avoidance opening 131 at the top of the vertical purlin 1 is inserted into the second wing plate 22, and then the bottom end of the vertical purlin 1 is inserted into the third avoidance opening 221.

[0067] Option 3, not shown in the figure:

[0068] The ends of the reinforcement ribs 13 are not provided with first escape openings 131. Instead, the upper and lower second wing panels 22 are provided with third escape openings 221, into which the ends of the reinforcement ribs 13 can be inserted. In the third scheme, the vertical purlins 1 and transverse purlins 2 are transported to the construction site in their original form. During assembly, the upper and lower transverse purlins 2 are first secured to the upper and lower floor slabs. The vertical purlin 1 is then horizontally inserted between the two transverse purlins 2, with the top and bottom ends of the vertical purlin 1 inserted into the two third escape openings 221.

[0069] Option 4, please refer to Figure 9 :

[0070] Two second clipping plates 132 are connected to the first web 11 at both ends of the stiffener 13. Second clipping interfaces 222 are formed on the second wing 22 to clip into the second clipping plates 132. In Option 4, the vertical purlins 1 and transverse purlins 2 are transported to the construction site in their component parts. During assembly, the upper and lower transverse purlins 2 are first secured to the upper and lower floor slabs. The vertical purlin 1 is then horizontally inserted between the two transverse purlins 2, so that the two second clipping portions 132 at the top and bottom ends of the vertical purlin 1 are respectively inserted into the two second clipping interfaces 222.

[0071] Among them, the second clipping plate 132 is perpendicular to the first web 11, and vertically extending hook portions 133 are formed at both ends of the second clipping plate 132 on the side away from the first web 11. The thickness of the second clipping plate 132 is less than 1.5 mm, and the width of the second card interface 222 is greater than the thickness of the second clipping plate 132.

[0072] During the process of inserting the second snap-in plate 132 into the second snap-in interface 222, the second snap-in plate 132 produces elastic deformation so that the two inverted hooks 133 are squeezed into the interior of the second snap-in interface 222. After the inverted hooks 133 pass through the second snap-in interface 222, the second snap-in plate 132 restores its original shape through its own elastic force, and the two inverted hooks 133 are snapped onto the side of the second snap-in interface 222 away from the first web 11.

[0073] Option 5, not shown in the figure:

[0074] A first avoidance opening 131 is provided at the upper end of the reinforcing rib 13 , a second clamping plate 132 is connected to the lower end of the first web 11 , and a second clamping interface 222 is formed on the second wing plate 22 for clamping with the second clamping plate 132 .

[0075] When scheme five is adopted, the vertical purlins 1 and the transverse purlins 2 are transported to the construction site in a component state. During assembly, the upper and lower transverse purlins 2 are first fixed to the upper and lower floor slabs, and then the first avoidance opening 131 at the top end of the vertical purlin 1 is inserted into the second wing plate 22, and then the second clip plate 132 at the bottom end of the vertical purlin 1 is inserted into the second clip interface 222.

[0076] In Example 1, when the prefabricated wall is subjected to a horizontal thrust, the thrust is transmitted to the second wing plate 22 of the transverse purlin 2 through the vertical purlin 1. The second wing plate 22 may be compressed inward or expanded outward due to the lateral deformation of the vertical purlin 1, thereby causing the prefabricated wall to tilt.

[0077] Moreover, the second web 21 may bend due to the deformation of the second wing 22. When the second web 21 arches upward or sinks downward, a gap appears between the second web 21 and the upper and lower floor slabs, affecting the fire prevention and sound insulation effects of the assembled wall.

[0078] In order to solve the above technical problems, it is necessary to enhance the performance of the transverse keel 2 in resisting horizontal lateral forces, while not isolating the core plate 5. Usually, the technical problem is solved by increasing the thickness of the transverse keel 2. However, the increase in the thickness of the transverse keel 2 will lead to an increase in the load borne by the vertical keel 1. Therefore, it is necessary to increase the thickness of the vertical keel 1 and the reinforcement rib 13.

[0079] Example 2, please refer to Figure 4 、 5 、6.

[0080] On the basis of embodiment 1, the upper transverse keel 2 of the two transverse keels 2 further includes: a third web 23 and a support plate 24;

[0081] The two sides of the third web 23 are connected to one end of the two second wing plates 22 away from the second web 21. A plurality of support plates 24 are connected between the second web 21 and the third web 23. The support plates 24 are parallel to the second wing plates 22. The middle part of the third web 23 is arched toward the second web 21 and fits the second web 21, so that the cross section of the transverse keel 2 presents an arch bridge shape.

[0082] In embodiment 2, the middle portion of the second web 21 is supported by the third web 23 and the support plate 24 to improve the compressive resistance of the transverse keel 2 in the horizontal direction.

[0083] Compared with the technical means of directly increasing the thickness of the transverse keel 2 , under the premise that the total weight of the transverse keel 2 is the same, the compressive performance of Example 2 in the horizontal direction is better than the technical means of directly increasing the thickness of the transverse keel 2 .

[0084] Regarding fire prevention issues: the middle part of the third web 23 is close to the bottom surface of the second web 21, and the width of the gap forming a fire weak point does not exceed the total thickness of the second web 21 and the third web 23. Filling fireproof cotton between the second web 21, the second wing plate 22 and the third web 23 can further improve the fire prevention performance of the cross keel 2; the support plate 24 is parallel to the wall panel 4, so the gap between the support plate 24 and the core panel 5 will not form a fire weak point.

[0085] The third web 23 is provided with a second avoidance opening 231 for avoiding the reinforcing rib 13 , so that the top end of the reinforcing rib 13 can abut against the bottom surface of the second web 21 .

[0086] The cost of connecting the second web 21 , the second wing plate 22 , the third web 23 and the support plate 24 by welding is relatively high.

[0087] The cost of welding is proportional to the length of the weld. In order to reduce the cost of welding, the length of the weld needs to be reduced.

[0088] Example 3, please refer to Figure 7 .

[0089] The second web 21 includes: a first sub-web 211 and a second sub-web 212 , wherein the second sub-web 212 has two sub-webs 212 and is welded to two sides of the first sub-web 211 ;

[0090] The first sub-web 211 and the support plate 24 are an integral piece, and the two support plates 24 are respectively connected to both sides of the first sub-web 211;

[0091] The second sub-web 212 , the second wing plate 22 and the third web 23 are sequentially connected and are an integral piece.

[0092] In the above embodiment, the first sub-web 211 and the support plate 24 are formed by stamping and bending one steel plate, and the second sub-web 212 , the second wing plate 22 and the third web 23 are formed by stamping and bending another steel plate.

[0093] Compared with Example 2, the number of parts constituting the transverse keel 2 in Example 3 is reduced from 4 to 2, thereby reducing the length of the weld and shortening the assembly process.

[0094] In order to reduce the difficulty of assembling the combined keel and reduce the number of welding fixtures on the construction site:

[0095] Preferably, an outwardly extending plug-in plate 241 is formed at one end of the support plate 24 facing the third web 23, and the plug-in plate 241 is perpendicular to the second web 21. A plug-in port 232 corresponding to the plug-in plate 241 is formed on the third web 23. When the plug-in plate 241 is inserted into the interior of the plug-in port 232, the surfaces of the first sub-web 211 and the second sub-web 212 are flush.

[0096] Preferably, a first snap-in plate 213 extending outward is formed at both ends of the second sub-web 212, the first snap-in plate 213 is parallel to the second sub-web 212, and a first snap-in interface 121 corresponding to the first snap-in plate 213 is formed on the first wing plate 12. When the first snap-in plate 213 is snapped into the interior of the first snap-in interface 121, the outer wall of the first snap-in plate 213 is flush with the outer wall of the first wing plate 12.

[0097] The above embodiment can preliminarily clamp the vertical keel 1 and the horizontal keel 2 together, so that on-site construction workers can assemble the combined keel into a correct shape without using special welding jigs.

[0098] Before on-site assembly, hanging holes are pre-drilled on the second sub-web 212, and then the integrated part consisting of the first sub-web 211 and the support plate 24 is welded into one piece with the integrated part consisting of the second sub-web 212, the second wing plate 22 and the third web 23. Then, during on-site assembly, expansion bolts are used to connect the hanging holes on the second sub-web 212 so that the transverse keel 2 is suspended below the upper floor slab.

[0099] In addition, in Examples 1-3, there are the following technical problems:

[0100] Fireproof cotton is used as the core board 5. The core board 5 is gradually compressed under the action of its own weight, so that the top wall of the core board 5 itself gradually separates from the upper floor board. Over time, a gap appears between the core board 5 and the upper floor board.

[0101] In order to solve the above technical problems, please refer to Example 4. Figure 10 .

[0102] A metal mesh 7 is fixedly connected between the upper and lower horizontal purlins 2. The metal mesh 7 is parallel to the wall panel 4. The metal mesh 7 extends from one side of the wall panel 4 to the other side of the wall panel 4. The core panels 5 are installed from both sides of the metal mesh 7 in the thickness direction, so that the metal mesh 7 is sandwiched between the two core panels 5, and the core panel 5 is partially embedded in the grid of the metal mesh 7 through its own expansion.

[0103] When fireproof cotton is used as the core board 5, the fireproof cotton is partially embedded in the grid of the metal mesh 7 so that every part of the fireproof cotton in the height direction is frictionally connected with the metal mesh 7, thereby reducing the degree of falling of the fireproof cotton due to its own weight.

[0104] In addition, an assembled wall is provided, comprising any one of the aforementioned combined purlins, and a wall panel 4, a core panel 5, and a metal mesh 7; two wall panels 4 are parallel to each other and connected by a combined purlin, a plurality of combined purlins are arranged side by side and vertically, the wall panel 4, the core panel 5 and the metal mesh 7 are parallel to each other, and the core panel 5 and the metal mesh 7 both extend from one side of the wall panel 4 to the other side of the wall panel 4; the metal mesh 7 and the combined purlin are fixedly connected, the core panel 5 and the metal mesh 7 both pass through the through hole 3, the core panel 5 is sandwiched by the wall panel 4, and the core panel 5 is respectively installed on both sides of the metal mesh 7 in the thickness direction, and the core panel 5 is partially embedded in the grid of the metal mesh 7 due to its own expansion.

[0105] The above-mentioned prefabricated wall may include a wall frame, which is not shown in the figure.

[0106] When the prefabricated wall is assembled in the factory and transported to the site as a whole, the edges of the wall panels are connected to the wall frame, which can be made of square tubes.

[0107] When the prefabricated wall is transported to the site in the form of parts and then assembled on site, the wall frame is not required. The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the essence and scope of protection of the present invention, and such modifications or equivalent substitutions should also be regarded as falling within the scope of protection of the embodiments of the present invention.
