Description

Technical Field

[0001] The invention relates to a method for realizing T-type connection of a lightweight wall, and belongs to the technical field of lightweight wall assembly. Background Art

[0002] Lightweight wall is a building structure technology that aims to build a wall system with low weight and high performance by using lightweight materials and innovative design methods. This technology is widely used in modern buildings and has many advantages, such as easy installation, energy saving, environmental protection and high flexibility. Figure 1 As shown in the figure, the main skeleton structure of a common lightweight wall is mainly formed by connecting horizontally arranged light steel keels and vertically arranged light steel keels. The light steel keels in this type of lightweight wall are arranged in the same manner. When a T-shaped connection is required (such as at the intersection of the walls), the arrangement direction of the two lightweight walls to be connected will be vertical, such as Figure 2 and Figure 3 As shown, Figure 2 This is a structural diagram of a T-type connection for this type of lightweight wall. Figure 3 This is another structural diagram for T-type connection of this type of lightweight wall. If it is connected directly with connecting parts such as self-tapping screws, then Figure 2 In this case, the web of the light steel keel at one end of one lightweight wall needs to be connected to the waist height of the light steel keel at the middle of another lightweight wall. Figure 3 In this case, the web of the light steel keel at one end of one lightweight wall needs to be connected to the waist height of the two light steel keels in the middle of the other lightweight wall. The contact surfaces in both cases are not equal ( Figure 3 The extra waist height of the two light steel keels in the middle is used to provide a support and fixing surface for the subsequent inner sealing work. Figure 2 The subsequent inner sealing work is not considered in this case), which leads to the phenomenon that the waist height of the light steel keel is prone to deformation.

[0003] Therefore, in the prior art, when such lightweight walls need to be T-connected, they are usually connected at the junction of the two side keels using connectors, and then reinforced with tie straps or angle irons. Although this method can ensure the stability of the light steel keels on both sides, it requires additional tie straps or angle irons, which will extend the construction time. In addition, the installation of tie straps and angle irons also requires the insertion of additional self-tapping screws. The insertion of self-tapping screws is very dependent on the construction experience of the operator. Improper operation may damage the structure of the light steel keel and affect its strength.

The reinforcing keels cooperate with the arrangement of the second vertical keels on the corresponding sides, so that an I-beam-like structure can be formed in the middle of the second wall. Compared with the keel structure of the C-shaped structure, the I-beam-like structure has better bending strength and shear strength due to the cross-sectional shape of the I-beam. Especially when bearing loads, its bearing capacity is better than that of the C-shaped structure. At the same time, the cross-sectional shape of the I-beam gives it better stability when under pressure, reducing the possibility of lateral instability. In addition, the arrangement of the reinforcing keels can provide sufficient supporting and fixing surfaces for the plates at the fixing positions when the inner side sealing work is subsequently carried out, so as to facilitate the sealing work. Compared with the prior art, it has the advantages of stable structure and convenient construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1: Please refer to Figures 1 to 4 This embodiment provides a method for realizing a lightweight wall T-type connection, comprising the following steps: The first step: determine the number of first wall panels 1 and second wall panels 2 used for T-shaped connection according to the design drawings; that is, determine the positions where T-shaped connection is required according to the actual design drawings, and then produce the corresponding number of first wall panels 1 and second wall panels 2 according to the number of T-shaped connection positions. It should be noted that one first wall panel 1 is matched with one second wall panel 2 and corresponds to one T-shaped connection position.

[0022] Step 2: Determine the structural composition of the first wall panel 1 and the second wall panel 2; the first wall panel 1 is composed of a first vertical keel 3 and a first transverse keel 4 provided at both ends of the first vertical keel 3, and the second wall panel 2 is composed of a second vertical keel 5 and a second transverse keel 6 provided at both ends of the second vertical keel 5. The number of first vertical keels 3, first transverse keels 4, second vertical keels 5 and second transverse keels 6 required for the first wall panel 1 and the second wall panel 2 can be determined according to actual needs and are not limited here. In this embodiment, the first wall panel 1 is composed of three first vertical keels 3 and two first transverse keels 4, and the second wall panel 2 is composed of four second vertical keels 5 and two second transverse keels 6, wherein two second vertical keels 5 are provided in the middle of the second wall panel 2, and the openings of the two second vertical keels 5 are arranged relative to each other to form a mouth shape. At the same time, in order to ensure the connection stability during the subsequent T-type connection, in the present embodiment, the shape, size, length and other parameters of the first vertical keel 3 and the second vertical keel 5 are exactly the same, and the first vertical keel 3 and the second vertical keel 5 are selected as light steel keels with a web length of about twice the waist height.

[0023] Step 3: Carry out the molding and delivery work of the first wall panel 1 and the second wall panel 2; according to the setting drawings, mark the positions of each keel on the corresponding wall panel, and then according to the marks, open the first connection hole 7 on the web of the first vertical keel 3 located at the end position of one side of the first wall panel 1, and open the second connection hole 8 on the web of the second vertical keel 5 located at the end position of one side of the second wall panel 2, and the second connection hole 8 can be aligned with the first connection hole 7. The specific number and distribution of the first connection holes 7 on the first wall panel 1 can be determined according to the length of the first vertical keel 3, and there is no restriction here. The second connection holes 8 on the two second vertical keels 5 can be set in a one-to-one correspondence with the first connection holes 7 on the first vertical keel 3, that is, if the first connection holes 7 are opened on the first wall panel 1 with 4, 6, or 8, then the number of second connection holes 8 on each second vertical keel 5 located in the middle is 2, 3, or 4. Then, the fixing part of the first connecting component is installed in the first vertical keel 3 with the first connecting hole 7 in the first wall panel 1 and in the second vertical keel 5 with the second connecting hole 8 in the second wall panel 2. Then, the first vertical keel 3 and the first transverse keel 4 are connected according to the design drawing to form the first wall panel 1, and the second vertical keel 5 and the second transverse keel 6 are connected to form the second wall panel 2.

[0024] The specific assembly method of the first wall panel 1 and the second wall panel 2 is: place one of the first transverse keels 4 on the placement surface so that its waist height is set vertically upward, and then place three first vertical keels 3 on this first transverse keel 4, the placement points are the two ends and the middle position of this first transverse keel 4, and the first vertical keels 3 placed on the two ends of this first transverse keel 4 are opened and arranged opposite to each other, and then, another first transverse keel 4 is placed on the top of these three first vertical keels 3, and its waist height is set vertically downward, and then the first vertical keels 3 and the first transverse keels 4 are fixed by using self-tapping screws or other fixed connection methods to complete the assembly of the first wall panel 1.

[0025] Place one of the second transverse keels 6 on the placement surface so that its waist height is set vertically upward, and then place four second vertical keels 5 on this second transverse keel 6, and the placement points are the two ends and the middle position of this second transverse keel 6. Two second vertical keels 5 are placed in the middle position of this second transverse keel 6, and the openings of these two second vertical keels 5 are relatively set to form a mouth shape. The second vertical keels 5 placed on the two ends of this second transverse keel 6 are opened and relatively set, and then, place another second transverse keel 6 on the top of the four second vertical keels 5, and set its waist height vertically downward, and then fix the second vertical keels 5 and the second transverse keels 6 by using self-tapping screws or other fixed connection methods to complete the assembly of the second wall panel 2.

[0026] Step 4: Carry out on-site installation of the first wall panel 1 and the second wall panel 2; transport the manufactured first wall panel 1 and the second wall panel 2 to the site, and then hoist the second wall panel 2 to the desired position and fix it according to the design drawings. It can be fixed by driving anchor bolts or by using external support rods 23 for support and fixation. Then, hoist the first wall panel 1 to the desired position, so that the web of the first vertical keel 3 with the first connecting hole 7 in the first wall panel 1 is abutted against the waist height of the two second vertical keels 5 with the second connecting holes 8 in the second wall panel 2, and the first connecting hole 7 is aligned with the corresponding second connecting hole 8. At the same time, it is also necessary to make the two side edges of the first wall panel 1 and the outer walls of the webs on the corresponding sides of the two second vertical keels 5 forming a mouth shape in the second wall panel 2 are on the same horizontal line, and then the first connecting component is passed through the first connecting hole 7 and the second connecting hole 8 to complete the T-type connection of the first wall panel 1 and the second wall panel 2.

[0027] Through the above-mentioned arrangement, by connecting the first vertical keel 3 with the two second vertical keels 5, the contact surface when the first wall panel 1 and the second wall panel 2 are connected can be expanded, so that the connection position of the first wall panel 1 and the second wall panel 2 has sufficient structural strength and connection stability, thereby eliminating the need for additional tie straps or angle irons for reinforcement, avoiding the insertion of additional self-tapping screws, and saving construction time. At the same time, by adopting a pre-punching process, that is, the connection holes on the first wall panel 1 and the second wall panel 2 are all punched during factory production and processing, and there is no need to punch holes on the construction site, which can further save construction time.

[0028] In this embodiment, the first connection assembly used in the third step and the fourth step of the above-mentioned implementation method includes a first connection member 10, a second connection member 11 and a first connection screw 12, wherein the first connection member 10 and the second connection member 11 are the fixing parts, and the first connection screw 12 is the connection part. The first connection member 10 and the second connection member 11 are both arranged in an L-shaped structure; a first through hole 13 with an aperture adapted to the first connection screw 12 is provided on both the lateral end and the vertical end of the first connection member 11; a first stretching hole 14 with a threaded structure inside is provided on both the lateral end and the vertical end of the second connection member 11, and the first stretching hole 14 is processed by a punching and stretching method commonly used in the prior art, and the threaded structure of each first stretching hole 14 is adapted to the threaded structure of the first connection screw 12, and the first stretching holes 14 on both sides are arranged to extend vertically along the inner side of the corresponding side end of the second connection member 11; the first connection screw 12 can movably pass through the first connection hole 7, the second connection hole 8, the first through hole 13 and the threaded connection hole 8. Connect to the first stretching hole 14; when installing the first connector 10 and the second connector 11, take the first connector 10 corresponding to the number of the first connection holes 7, place the first connector 10 in the first vertical keel 3 with the first connection holes 7, and align the through holes 13 with the first connection holes 7 one by one, and then temporarily fix the first connector 10 in the first vertical keel 3; take the second connector 11 corresponding to the number of the second connection holes 8, place the second connector 11 in the two second vertical keels 5 located at the end position of one side of the second wall panel 2, and align the first stretching hole 14 with the second connection holes 8 one by one, and then temporarily fix the second connector 11 in the second vertical keel 5, so as to facilitate the subsequent installation work. The temporary fixing method of the first connector 10 and the second connector 11 can be a common temporary fixing method of snap connection, or other common temporary fixing methods, which are not limited here. When the first connecting screw 12 is used to connect the first wall panel 1 and the second wall panel 2, the first connecting screw 12 passes through the first through hole 13, the first connecting hole 7, the second connecting hole 8 in sequence and is threaded into the first stretching hole 14 to connect the first connecting member 10 and the second connecting member 11 together, thereby completing the T-type connection of the first wall panel 1 and the second wall panel 2.

[0029] During construction, a flat washer m and a spring washer n can be inserted into the first connecting screw 12. The setting of the flat washer m and the spring washer n can prevent the first connecting screw 12 from loosening when playing a connecting role, thereby ensuring the stability of the connection between the first connecting screw 12 and the first wall panel 1 and the second wall panel 2.

[0030] In order to avoid the deformation of the first connecting member 10 as much as possible, in this embodiment, first bending reinforcement ribs 15 are provided at both side edges of the horizontal end and the vertical end of the first connecting member 10. The first bending reinforcement ribs 15 on both sides are extended along the inner side of the corresponding side ends of the first connecting member 10. The ends of the first bending reinforcement ribs 15 on the same side that are close to each other are also arranged in a close fit. The middle part of each first bending reinforcement rib 15 is also arched. The arrangement of the first bending reinforcement ribs 15 can effectively disperse stress and reduce stress concentration, so as to improve the overall strength, rigidity and fatigue resistance of the first connecting member 10. At the same time, the first bending reinforcement ribs 15 with an arched middle part are less likely to crack or deform compared to the straight edge, so as to well avoid the deformation of the first connecting member 10.

[0031] In order to avoid the deformation of the second connecting member 11 as much as possible, in this embodiment, second bending reinforcement ribs 16 are provided at both side edges of the lateral end and the vertical end of the second connecting member 11. The second bending reinforcement ribs 16 on both sides are extended along the inner side of the corresponding side ends of the second connecting member 11, and the adjacent ends of the second bending reinforcement ribs 16 on the same side are also arranged in a close fit, and the middle part of each second bending reinforcement rib 16 is also arched. The arrangement of the second bending reinforcement ribs 16 can effectively disperse stress and reduce stress concentration, so as to improve the overall strength, rigidity and fatigue resistance of the second connecting member 11. At the same time, the second bending reinforcement ribs 16 with an arched middle part are less likely to crack or deform compared to the straight edge, so as to well avoid the deformation of the second connecting member 11.

[0032] In order to further strengthen the structural strength of the connection position between the second wall panel 2 and the first wall panel 1, in this embodiment, the second step may also include the following steps: two reinforcing keels 9 are further arranged on both sides of the two second vertical keels 5 located in the middle of the second wall panel 2, and the parameters such as the shape, size, and length of the reinforcing keels 9 are the same as those of the second vertical keels 5. The webs of the two reinforcing keels 9 are closely arranged with the webs of the second vertical keels 5 on the corresponding side, and the reinforcing keels 9 can be fixedly connected with the second vertical keels 5 on the corresponding side by common fixed connection methods such as bolt connection. Through the above-mentioned settings, the two reinforcing keels 9 cooperate with the two second vertical keels 5, so that two I-beam-like structures can be formed in the middle position of the second wall, that is, one reinforcing keel 9 cooperates with one second vertical keel 5 to form an I-beam-like structure. Compared with the keel structure of the C-shaped structure, the cross-sectional shape of the I-beam-like structure gives it better bending strength and shear strength, especially when bearing loads, its bearing capacity is better than that of the C-shaped structure. At the same time, the cross-sectional shape of the I-beam gives it better stability when under pressure, reducing the possibility of lateral instability. In addition, the setting of the reinforcing keel 9, when the inner side sealing work is carried out later, at the fixing place of the plate, the reinforcing keel 9 can provide sufficient support and fixing surface for the plate to facilitate the sealing work.

[0033] In the actual construction process, there is also a special T-type connection, namely a cross-type connection, which requires that the first wall panels are arranged on both sides of the second wall panel, and then the first wall panels on both sides are connected to the second wall panels. To adapt to this special T-type connection, we propose embodiment 2.

[0034] Example 2: Please refer to 5 and Figure 6 This embodiment provides a method for realizing a lightweight wall T-type connection, comprising the following steps: The first step: determine the number of first wall panels 1 and second wall panels 2 used for special T-type connection, i.e., cross-type connection, according to the design drawings; that is, determine the positions where cross-type connection is required according to the actual design drawings, and then produce the corresponding number of first wall panels 1 and second wall panels 2 according to the number of cross-type connection positions. It should be noted that two first wall panels 1 cooperate with one second wall panel 2 to correspond to one cross-type connection position.

[0035] Step 2: Determine the structural composition of the first wall panel 1 and the second wall panel 2; the first wall panel 1 is composed of a first vertical keel 3 and a first transverse keel 4 provided at both ends of the first vertical keel 3, and the second wall panel 2 is composed of a second vertical keel 5 and a second transverse keel 6 provided at both ends of the second vertical keel 5.
