Description

Technical Field

[0001] This invention relates to the field of prefabricated wall systems, and more specifically to a prefabricated wall system with double-sided assembly. Background Technology

[0002] The related technologies of prefabricated walls disclosed in this invention are disclosed in:

[0003] A prefabricated wall structure is disclosed in Chinese Patent Publication No. CN114319633A.

[0004] The assembly method for some prefabricated walls is as follows: install columns between the top and bottom joists, and install the wall panels onto the columns. The wall panels are installed along their own thickness. To prevent the wall panels from moving along their own length, limiters are designed between the wall panels. Due to the existence of the limiters, the installation sequence of the wall panels is subject to strict requirements. Construction workers often have to move the wall panels back and forth from the inside and outside sides, resulting in low construction efficiency.

[0005] To improve construction efficiency, it is necessary to improve existing prefabricated walls so that their installation sequence and direction are not affected by limiting components. Summary of the Invention

[0006] The purpose of this invention is to provide a prefabricated wall with double-sided assembly, so as to solve the technical problem that the installation sequence and installation direction of existing prefabricated walls are affected by limiting components, resulting in complicated assembly process and affecting assembly efficiency.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0008] A prefabricated wall assembly with double-sided assembly includes: wall units and columns, a plurality of columns being vertically arranged side by side, each wall unit being connected to a column along its own thickness direction, and each column being positioned between two adjacent wall units along its own thickness direction; each wall unit includes a wall panel and a limiting member, the limiting member being connected to one end of the wall panel in the width direction, and two wall units adjacent in their own width direction and respectively located on both sides of the column in their own thickness direction being connected by their respective limiting members, the limiting members being used to restrict the movement of two adjacent wall panels along their own width direction; the limiting member includes: a first The wall panel comprises a wing plate, a first web plate, and a second wing plate; wherein the first wing plate is connected parallel to the side of the wall panel near the column, and at least a portion of the first wing plate is exposed on the outside of the wall panel; the first web plate is perpendicularly connected to the end of the first wing plate away from the wall panel, the first web plate extends in a direction away from the wall panel, and the distance between the distal end of the first web plate and the adjacent wall panel is equal to the thickness of the first wing plate; the second wing plate is perpendicularly connected to the distal end of the first web plate, the first wing plate and the second wing plate are located on the same side of the first web plate, and the second wing plate partially overlaps with the first wing plate of the adjacent limiting member.

[0009] Furthermore, the wall panel and the first wing plate or the second wing plate are connected by fasteners, the width of the first wing plate is greater than the width of the second wing plate, and the difference between the widths of the first wing plate and the second wing plate is greater than the diameter of the fasteners.

[0010] Furthermore, a first flange is vertically connected to one end of the first wing plate near the wall plate, and the first flange extends in a direction away from the wall plate.

[0011] Furthermore, the column includes a third wing plate and a second web plate; the two third wing plates are respectively parallel to and attached to two adjacent wall panels located on both sides of the column, and the two ends of the second web plate are respectively perpendicularly connected to the middle ends of the two third wing plates.

[0012] Furthermore, the wall unit also includes a clamp for connecting the wall panel and the column. The clamp includes a third web, a fourth wing, and a second flange. The third web is connected parallel to the wall panel, and the two fourth wings are respectively connected perpendicularly to the two ends of the third web in the horizontal direction. The fourth wings extend away from the wall panel and bend towards the other fourth wing to form the second flange. The included angle between the second flange and the fourth wing is an acute angle. The distance between two adjacent fourth wings is greater than the width of the third wing, and the distance between the distal ends of two adjacent second flanges is less than the width of the third wing. The fourth wing and the second flange are elastic, allowing the third wing to push the two second flanges, causing them to elastically deform and move away from each other, thereby engaging the third wing in the groove formed by the third web, the fourth wing, and the second flange.

[0013] Furthermore, the middle end of the third web plate forms a protrusion in a direction away from the wall panel, so as to form a positioning hole between the third web plate and the wall panel. Gaps are provided between the two ends of the third web plate in the length direction and the top and bottom walls of the wall panel. The wall unit also includes a connector for connecting two adjacent wall units in height. The connector includes a positioning post and a load-bearing plate. The positioning post is vertically inserted into two adjacent positioning holes in the height direction. The load-bearing plate is formed at the middle end of the positioning post and extends outward in the horizontal direction. The thickness of the load-bearing plate is equal to the width of the gap. The load-bearing plate abuts against the end faces of two adjacent clamps in the height direction.

[0014] Furthermore, after the positioning column is inserted into the positioning hole of the wall unit located below, the load-bearing plate is fixedly connected to the column.

[0015] Furthermore, the wall panel and the clamp are connected by a slide rail, which is parallel to the width direction of the wall panel, and the slide rail is slidably connected to the clamp.

[0016] Furthermore, a sliding groove is provided on the portion of the third web plate where the protrusion is not formed. The sliding groove extends along the width direction of the wall plate. The slide rail is inserted into the sliding groove and slidably connected to the sliding groove. The length of the slide rail is less than the length of the sliding groove.

[0017] Further, the slide rail includes: a fourth web, a fifth wing, and a third flange; the fourth web is connected parallel to the wall panel, and the two fifth wing plates are respectively perpendicularly connected to the two ends of the fourth web in the vertical direction. The fifth wing plates extend in a direction away from the wall panel, and the fifth wing plates bend in a direction close to the fourth web and away from the other fifth wing plate to form the third flange. The included angle between the third flange and the fifth wing plate is an acute angle. The distance between two adjacent fifth wing plates is less than the vertical dimension of the slide groove, and the distance between the distal ends of two adjacent third flanges is greater than the vertical dimension of the slide groove. The fifth wing plates and the third flange are elastic, so that the two third flanges can be squeezed into the interior of the slide groove, thereby clamping the third web between the wall panel and the third flange.

[0018] Compared with the prior art, this application has the following advantages:

[0019] A prefabricated wall assembly with double-sided assembly is provided, including columns, wall panels and limiting members. The limiting members are only used to connect two wall units that are adjacent in their width direction and located on both sides of the column in their thickness direction. The wall units can be installed asymmetrically from both sides of the column, or the wall units on one side of the column can be installed first and then the other side can be installed. The direction and order of assembly are not restricted. Attached Figure Description

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] A prefabricated wall assembly with double-sided assembly, the installation sequence and direction of which are not affected by limiting components.

[0036] Example 1, please refer to Figure 1-5 .

[0037] The prefabricated wall includes: wall units and columns 3; multiple columns 3 are arranged vertically and side by side, and the columns 3 are used to connect the upper and lower floor slabs; the wall units are connected to the columns 3 along their own thickness direction, and the columns 3 are arranged between two adjacent wall units along their own thickness direction.

[0038] The wall unit includes a wall panel 1 and a limiting member 2. The limiting member 2 is connected to one end of the wall panel 1 in the width direction. Two wall units that are adjacent in their own width direction and located on both sides of the column 3 in their own thickness direction are connected by their respective limiting members 2. The limiting member 2 is used to restrict the movement of two adjacent wall panels 1 along their own width direction and to fix the adjacent wall panels 1 and the opposing wall panels 1 on both sides of the column 3 firmly.

[0039] The limiting member 2 includes: a first wing plate 21, a first web plate 22, and a second wing plate 23;

[0040] in,

[0041] The first wing plate 21 is connected in parallel to the side of the wall panel 1 near the column 3, and at least a portion of the first wing plate 21 is exposed on the outside of the wall panel 1 so that two adjacent wall panels 1 can overlap on the same first wing plate 21.

[0042] The first web plate 22 is vertically connected to the end of the first wing plate 21 away from the wall plate 1. The first web plate 22 extends in a direction away from the wall plate 1. The distance between the far end of the first web plate 22 and the adjacent wall plate 1 is equal to the thickness of the first wing plate 21, so that the far end of the first web plate 22 abuts against the first wing plate 21 of the adjacent other limiting member 2.

[0043] The second wing plate 23 is vertically connected to the far end of the first web plate 22. The first wing plate 21 and the second wing plate 23 are located on the same side of the first web plate 22. The second wing plate 23 partially overlaps with the first wing plate 21 of the adjacent limiting member 2 so that the self-tapping screw can pass through the wall panel 1, the first wing plate 21 and the second wing plate 23 at the same time.

[0044] Based on the above embodiments, prefabricated walls can be assembled in three different sequences.

[0045] Sequence 1: Please refer to Figure 1 , 2 5. The wall units are installed asymmetrically from both sides of the column 3. The wall units that are adjacent in their own width direction and located on both sides of the column 3 are preferentially connected to each other and to the column 3. Then the remaining wall units are installed asymmetrically. During installation, two wall units should be inserted obliquely into the gap between two adjacent but asymmetrical wall units. After the two wall units are connected by their respective limiting pieces 2, the two wall units are rotated to fit against their respective adjacent columns 3.

[0046] Sequence Two: Please refer to Figure 3 , 4 5. The wall units are connected to one side of the column 3 and installed sequentially. After all the wall units are installed, they are connected to the other side of the column 3 and installed sequentially.

[0047] Sequence 3: Please refer to Figure 7 , 5 After the wall unit is assembled, it is hoisted and fitted onto column 3. This is suitable for construction scenarios where the upper end of column 3 is a free end and there is enough installation space at the upper end of column 3, such as partition walls in industrial buildings.

[0048] The wall panel 1 can be connected to the column 3 and the limiting part 2 by self-tapping screws. The assembler can choose to perform the assembly operation in sequence one or sequence two according to the principle of maximizing efficiency, based on factors such as the location of the materials on site, the location of the column 3, and the ease of transportation between the materials and the column 3.

[0049] Optional:

[0050] The wall panel 1 is connected to the first wing plate 21 or the second wing plate 23 by fasteners. The width of the first wing plate 21 is greater than the width of the second wing plate 23, and the difference between the widths of the first wing plate 21 and the second wing plate 23 is greater than the diameter of the fasteners, so that the wall panel 1 can be pre-connected to the limiting member 2 by self-tapping screws (fasteners).

[0051] Furthermore, in order to enhance the bending resistance of the first flange 21:

[0052] The first flange 24 is vertically connected to the end of the first wing plate 21 near the wall plate 1, and the first flange 24 extends in a direction away from the wall plate 1.

[0053] The first flange 24 serves as a reinforcing rib for the first flange 21.

[0054] Optional:

[0055] The column 3 includes a third wing plate 31 and a second web plate 32;

[0056] The two third wing plates 31 are respectively attached in parallel to the two adjacent wall panels 1 located on both sides of the column 3, and the two ends of the second web plate 32 are respectively perpendicularly connected to the middle ends of the two third wing plates 31.

[0057] In the above embodiment, the cross-section of the column 3 is I-shaped. The column 3 can be made directly from I-beams or formed by welding two C-shaped steels together.

[0058] When connecting column 3 and wall panel 1, self-tapping screws can be used to directly penetrate wall panel 1 and the third wing 31 or the fourth wing 42.

[0059] Example 1 lacks a structure that can quickly connect the column 3 and the wall unit. Connecting the two using self-tapping screws requires the participation of two construction workers. One construction worker is responsible for holding the wall unit, and the other construction worker is responsible for placing the wall unit in a suitable position and connecting the wall unit and the column 3 with self-tapping screws. This assembly process is inefficient.

[0060] Furthermore, in order to solve the above-mentioned technical problems, please refer to Embodiment 2. Figure 6 .

[0061] The wall unit also includes a clamp 4, which is used to connect the wall panel 1 and the column 3;

[0062] The clamp 4 includes: a third web plate 41, a fourth wing plate 42, and a second wing edge 43;

[0063] The third web plate 41 is connected to the wall plate 1 in parallel. The two fourth wing plates 42 are respectively connected to the two ends of the third web plate 41 in the horizontal direction. The fourth wing plate 42 extends away from the wall plate 1 and bends towards the other fourth wing plate 42 to form the second flange 43. The included angle between the second flange 43 and the fourth wing plate 42 is an acute angle.

[0064] The distance between two adjacent fourth wing plates 42 is greater than the width of the third wing plate 31, and the distance between the far ends of two adjacent second wing edges 43 is less than the width of the third wing plate 31.

[0065] The fourth flange 42 and the second flange 43 are elastic, so that the third flange 31 can push the two second flanges 43 to elastically deform and move away from each other, thereby making the third flange 31 snap into the groove formed by the third web plate 41, the fourth flange 42 and the second flange 43.

[0066] The clamp 4 is pre-fixed to the wall panel 1 with self-tapping screws. During the assembly operation, the construction personnel only need to hold the wall unit steady and push the wall panel 1 so that the clamp 4 can engage with the column 3 to complete the initial assembly. The entire process only requires one person to operate and the construction efficiency is high.

[0067] Furthermore, sometimes the distance between floors is large, requiring multiple layers of wall panels 1 to be stacked along the height direction to connect the upper and lower floor slabs. When using clamps 4 to connect wall panels 1 and columns 3, the weight of the upper wall panel 1 presses on the lower wall panel 1, which can easily cause the lower wall panel 1 to bend and deform.

[0068] To solve the above technical problems, please refer to Embodiment 3. Figure 7-10 .

[0069] The middle end of the third web plate 41 forms a protrusion 411 in the direction away from the wall plate 1, so that a positioning hole 412 is formed between the third web plate 41 and the wall plate 1, and gaps 413 are provided between the two ends of the third web plate 41 in the length direction and the top and bottom walls of the wall plate 1.

[0070] The wall unit also includes a connector 5, which is used to connect two adjacent wall units in height. The connector 5 includes a positioning post 51 and a load-bearing plate 52.

[0071] The positioning post 51 is vertically inserted into two adjacent positioning holes 412 in the height direction. The load-bearing plate 52 is formed at the middle of the positioning post 51 and extends outward in the horizontal direction. The thickness of the load-bearing plate 52 is equal to the width of the gap 413. The load-bearing plate 52 is used to abut against the end faces of two adjacent clamps 4 in the height direction.

[0072] The gap 413 is used to insert the load-bearing plate 52 so that two adjacent wall panels 1 in height can be connected seamlessly, and the load-bearing plate 52 can transfer the load of the upper wall unit to the clamp 4 of the lower wall unit.

[0073] After two adjacent wall units in the vertical direction are connected by connector 5, connector 5 can also prevent the two wall units from moving in the horizontal direction.

[0074] Furthermore, since the clamp 4 itself has weak compressive strength, the weight of the upper wall panel 1 pressing on the lower clamp 4 can easily cause the clamp 4 to deform. In order to solve the above technical problems...

[0075] After the positioning column 51 is inserted into the positioning hole 412 of the wall unit below, the load-bearing plate 52 is fixedly connected to the column 3.

[0076] The load-bearing plate 52 and the column 3 can be fixedly connected by welding or bolts so that the weight of the upper wall panel 1 is transferred to the column 3.

[0077] Furthermore, since errors are inevitable during construction and production, when there are many wall units at the same height, the assembly gaps between adjacent wall units in the horizontal direction are difficult to meet tolerance requirements.

[0078] To solve the above technical problems, please refer to Figure 9 and 11 .

[0079] The wall panel 1 and the clamp 4 are connected by a slide rail 6, which is parallel to the width direction of the wall panel 1, and the slide rail 6 is slidably connected to the clamp 4.

[0080] After the construction workers connect the wall panel 1 to the column 3 using the clamp 4, they can still slide the wall panel 1 a short distance along its own width direction to eliminate the assembly error between the wall panels 1 and the wall panels 1.

[0081] Furthermore, during the process of moving the wall panel 1, the position of the clamp 4 itself does not move, thereby avoiding the technical problem that the positioning holes 412 of two adjacent wall units in the height direction cannot be aligned due to the movement of the wall panel 1.

[0082] Furthermore, the conventional slide rail 6 itself has thickness. Using the conventional slide rail 6 to connect the wall panel 1 and the clamp 4 will result in a large gap 413 between the two, affecting the connection stability between the wall panel 1 and the column 3. In order to solve this problem.

[0083] A groove 414 is provided on the part of the third web plate 41 where no protrusion 411 is formed. The groove 414 extends along the width direction of the wall plate 1. The slide rail 6 is inserted in the groove 414 and is slidably connected with the groove 414. The length of the slide rail 6 is less than the length of the groove 414.

[0084] The difference in length between the slide groove 414 and the slide rail 6 is equal to the distance that the clamp 4 can move relative to the wall panel 1. Since the slide rail 6 is inserted inside the slide groove 414, the thickness of the slide rail 6 itself does not affect the tight fit between the clamp 4 and the wall panel 1.

[0085] Optional:

[0086] The slide rail 6 includes: a fourth web plate 61, a fifth wing plate 62, and a third wing flange 63;

[0087] The fourth web plate 61 is connected to the wall plate 1 in parallel. The two fifth flanges 62 are respectively connected to the two ends of the fourth web plate 61 in the vertical direction. The fifth flanges 62 extend away from the wall plate 1. The fifth flanges 62 are bent in a direction close to the fourth web plate 61 and away from the other fifth flange to form the third flange 63. The included angle between the third flange 63 and the fifth flange 62 is an acute angle.

[0088] The distance between two adjacent fifth flanges 62 is less than the vertical dimension of the groove 414, and the distance between the far ends of two adjacent third flanges 63 is greater than the vertical dimension of the groove 414.

[0089] The fifth flange 62 and the third flange 63 are elastic so that the two third flanges 63 can be squeezed into the interior of the groove 414, thereby clamping the third web plate 41 between the wall plate 1 and the third flange 63.

[0090] The fourth web plate 61 and the wall plate 1 are fixedly connected by self-tapping screws. The slide rail 6 and the slide groove 414 are directly engaged without affecting the relative sliding between them, thereby improving the assembly speed.

[0091] The above embodiments are merely 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 its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of the embodiments of the present invention.
