Description

Technical Field

[0001] The invention relates to the technical field of wall decoration, in particular to an installation structure of a four-in-one back-bolt type stone curtain wall hanging. Background Art

[0002] Stone curtain wall hangers are a type of structure used in the dry hanging method, a new type of construction technology for wall decoration. This method uses metal hangers to hang the facing stone directly on the wall or hang it on a steel frame without the need for grouting or gluing.

[0003] The application technology of stone curtain wall back bolts is relatively mature and its application is becoming more and more extensive. The traditional stone back bolt keel arrangement is that a stone slab is connected to two transverse keels through four back bolts to form a four-point suspension structure. Compared with the aluminum alloy hanger system, the extra transverse keel not only increases the complexity of on-site welding or bolt connection, but also correspondingly increases the construction cost. In addition, the upper and lower layers of stone slabs are relatively independent and only supported by the back bolts connected to the transverse keels. The weight of the stone slabs and external loads are directly transmitted to the transverse keels through the back bolts, resulting in stress concentration on the back bolts, stone slab interfaces and keel connection nodes. Under long-term cyclic loads, microcracks are easily caused to expand, and eventually lead to separation of the back bolt interface or brittle fracture of the stone, thereby reducing the stability of the stone suspension.

[0004] Therefore, it is urgent to provide a mounting structure that can suspend multiple stones and improve the stability after suspension. Summary of the Invention

[0005] Based on this, it is necessary to provide an installation structure for a four-in-one back-bolt stone curtain wall hanger, aiming to solve the problems caused by the existing stone curtain wall installation structure during use.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: the installation structure of the four-in-one back-bolt stone curtain wall hanger includes: a transverse keel, and a plurality of bolt holes are opened on the transverse keel.

[0007] It also includes a four-link hanger group, which is connected to the transverse keel and is used to hang four rectangularly distributed stone slabs. The four-link hanger group includes a fixing part connected to the transverse keel, and two hanging parts for installing the stone slabs are connected to the upper and lower ends of the fixing part. The fixing part and the hanging part are used to connect the four stone slabs as a whole at one level. The fixing part is also connected to a cross limiting part for supporting and limiting the gaps between the four stone slabs.

[0008] It also includes an integral connection group, which is connected to four hanging parts at the same time and is used to connect the four stone slabs as a whole. The integral connection group includes four connecting parts for connecting the four hanging parts to the corresponding stone slabs respectively. The four connecting parts are commonly connected with a locking part for limiting the overall position of the four connecting parts. The four connecting parts cooperate with the locking part for secondary integral connection of the four stone slabs.

[0009] Preferably, the hanging piece located at the upper end of the fixing piece is an upper mounting angle bracket, and the hanging piece located at the lower end of the fixing piece is a lower mounting angle bracket.

[0010] Preferably, the cross limiting portion includes a limiting bar installed on the fixing member through a fixing plate, the limiting bar is located between the two lower stone slabs, a T-shaped bar is provided on the upper end of the limiting bar, the T-shaped bar and the limiting bar are spliced into a cross shape and are located in the gap between the four stone slabs.

[0011] Preferably, the cross limiting portion also includes a sliding groove and a limiting countersunk hole respectively opened at the upper end of the fixing member, a sliding block fixedly connected to the T-bar is slidably connected in the sliding groove, and a limiting rod is connected to the sliding block and plugged into the limiting countersunk hole.

[0012] Preferably, the connecting portion includes supporting members respectively connected to four hanging members along the diagonal direction of the stone slab, and a corner joint is installed at one end of the supporting member away from the fixing member, and the corner joint is connected to the corner of the stone slab.

[0013] Preferably, the locking portion includes locking seats respectively installed on four supporting members, and a connecting piece is commonly connected between two adjacent locking seats.

[0014] Preferably, two baffles for limiting the installation position of the stone slabs are integrally formed on the three sections of the limit strip and the T-shaped strip.

[0015] To sum up, the present invention includes the following beneficial technical effects: the present invention uses a four-link hanger group to realize that a single horizontal keel supports multiple groups of four stone slabs at the same time, thereby reducing the amount of horizontal keels used, reducing the cost of installing multiple stone slabs, and reducing the workload of stone slab installation. The fixing parts and the four-link hanger group are integrated into the design, and a single set of hangers can cover four stone slabs, reducing the number of fixing parts and welding or bolt connection nodes, simplifying the construction process, and shortening the construction period.

[0016] The present invention forms a cross structure through the limit bars and T-bars, which are embedded in the gaps between the four stone slabs to provide lateral support force, disperse the dead weight of the stone slabs and external loads, reduce the single-point force pressure of the back bolts, and can provide each stone slab with a support point other than the hanging parts and the corner joints. The horizontal section of the T-bar is located between the upper and lower stone slabs, which transfers the load of the upper stone slab to the lower stone slab, forming a continuous support chain. Force can be transferred between the stone slabs of each layer, effectively avoiding the separation of the back bolt interface or brittle fracture of the stone due to the heavy stone slabs, thereby improving the stability of the stone slabs after installation.

[0017] The present invention cooperates with the cross-limiting part and the overall connection group to evenly transfer the weight of the stone slab to the keel system, thereby preventing the back bolt from being subjected to concentrated stress for a long time and reducing the risk of separation between the stone and the back bolt; and the entire connection piece is connected to the adjacent support parts through the locking seat to form a lateral rigid constraint to avoid displacement caused by external loads.

DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The installation structure of the four-in-one back-bolt stone curtain wall hanger includes a transverse keel 1, on which a plurality of bolt holes are opened.

[0031] During the specific work, the stone slab 4 is installed with existing back bolts at two corners along the diagonal line, and one of the back bolts is fixedly connected to the existing metal hanger with threads. Before the stone slab 4 is installed, multiple transverse keels 1 are prepared. The transverse keel 1 is the existing strip angle steel. Then, the existing multiple main keels are vertically installed on the wall with uniform spacing. Multiple transverse keels 1 distributed from top to bottom are connected between two adjacent main keels. The two ends of the transverse keel 1 are fixedly connected to the main keel by welding or bolting.

[0032] See Figure 1 、 Figure 2 、 Figure 4 and Figure 6 The installation structure of the four-in-one back-bolt stone curtain wall hanger also includes a four-link hanger group 2, which is connected to the transverse keel 1 and is used to hang four rectangularly distributed stone slabs 4. The four-link hanger group 2 includes a fixing member 21 connected to the transverse keel 1, and the fixing member 21 is also connected to a cross limiting portion 23 for supporting and limiting the gaps between the four stone slabs 4. The cross limiting portion 23 includes a limiting strip 231 installed on the fixing member 21 through a fixing plate.

[0033] During specific operation, the fixing part 21 is a U-shaped steel connecting part. The vertical section of the fixing part 21 is fixedly connected to the bolt hole on the transverse keel 1 through bolts, thereby realizing the function of fixed connection between the fixing part 21 and the transverse keel 1. When the fixing part 21 is connected, the limiting strip 231 is driven by the fixing plate to be installed in the working position.

[0034] See Figure 2 、 Figure 5 and Figure 6 The upper and lower ends of the fixing part 21 are connected to two hanging parts 22 for installing the stone slabs 4. The fixing part 21 and the hanging part 22 are used to connect the four stone slabs 4 as a whole at one level. The hanging part 22 located at the upper end of the fixing part 21 is the upper installation angle code 221, and the hanging part 22 located at the lower end of the fixing part 21 is the lower installation angle code 222.

[0035] During the specific work, the upper mounting angle code 221 and the lower mounting angle code 222 are both existing angle codes for hanging and installing the stone slab back bolts. The structures of the upper mounting angle code 221 and the lower mounting angle code 222 can be the same or different. The upper mounting angle code 221 and the lower mounting angle code 222 are fixedly connected to the upper and lower ends of the fixing part 21 by bolt connection or welding. Then, two stone slabs 4 with back bolts and metal hangers are selected, and the metal hangers on the two stone slabs 4 are assembled on the two lower mounting angle codes 222 respectively. The two stone slabs 4 are located on both sides of the limit bar 231. The limit bar 231 blocks the lower stone slab 4 during installation. As long as the lower stone slab 4 is close to the limit bar 231, it can be ensured that the metal hanger on the lower stone slab 4 and the lower mounting angle code 222 on the lower side are in the same vertical direction, thereby achieving a positioning effect on the installation of the lower stone slab 4, which facilitates the assembly of the lower stone slab 4 and the lower mounting angle code 222.

[0036] See Figure 4 and Figure 6 The limiting strip 231 is located between the two lower stone slabs 4 , and a T-shaped strip 232 is provided on the upper end of the limiting strip 231 . The T-shaped strip 232 and the limiting strip 231 are spliced into a cross shape and are located in the gap between the four stone slabs 4 .

[0037] See Figure 1 、 Figure 4 and Figure 6 The cross limiting portion 23 also includes a sliding groove 233 and a limiting countersunk hole 234 respectively opened at the upper end of the fixing member 21. A sliding block 235 fixedly connected to the T-shaped bar 232 is slidably connected in the sliding groove 233. The sliding block 235 is connected to a limiting rod 236 that is plugged into the limiting countersunk hole 234. Two blocking members 237 for limiting the installation position of the stone slab 4 are integrally formed on the three sections of the limiting bar 231 and the T-shaped bar 232.

[0038] When the two slabs 4 on the lower side are installed, the T-shaped bar 232 is on the side close to the fixing part 21. At this time, the T-shaped bar 232 and the limit bar 231 are staggered to avoid the horizontal section of the T-shaped bar 232 affecting the installation of the lower slab 4. After the two slabs 4 on the lower side are installed, the sliding block 235 is pushed. The sliding block 235 drives the T-shaped bar 232 to move in the direction of the limit bar 231 and moves to the upper end of the limit bar 231 to form a cross structure with the limit bar 231. At the same time, the horizontal section of the T-shaped bar 232 is located at the upper end of the two slabs 4 on the lower side. Then, two more slabs 4 with back bolts and metal hangers are selected, and the metal hangers on the two slabs 4 are installed on the two upper installation angle codes 221 in turn. At this time, the fixing part 21 is connected to four rectangularly distributed slabs 4 (such as Figure 6 and Figure 7 As shown), the number of fixing members 21 required for installing multiple stone slabs 4 is effectively reduced, the cost of installing multiple stone slabs 4 is reduced, and the workload of installing the stone slabs 4 is reduced.

[0039] The two upper stone slabs 4 are respectively located on both sides of the vertical section of the T-bar 232. The vertical section of the T-bar 232 and multiple blocking parts 237 simultaneously guide and limit the installation of the stone slab 4 in multiple directions, ensuring the rapid assembly of the stone slab 4 and the hanging parts 22. The horizontal section of the T-bar 232 is located between the upper and lower stone slabs 4, which can transmit force to the stone slab 4, ensuring that the stone slabs 4 on the upper and lower sides are balanced in force, and also provides a new support point for the stone slab 4, avoiding the stone slab 4 from exerting greater pressure on the hanging parts 22 and causing it to bend, thereby ensuring the stability of the stone slab 4 after installation.

[0040] See Figure 1 、 Figure 2 and Figure 6 The installation structure of the four-in-one back-bolt stone curtain wall hanger also includes an integral connection group 3, which is connected to the four hanging parts 22 at the same time and is used to connect the four stone slabs 4 as a whole. The integral connection group 3 includes four connecting parts 31 for connecting the four hanging parts 22 to the corresponding stone slabs 4 respectively. The four connecting parts 31 are commonly connected with a locking part 32 for limiting the overall position of the four connecting parts 31. The four connecting parts 31 cooperate with the locking part 32 for secondary overall connection of the four stone slabs 4.

[0041] See Figure 2 、 Figure 5 and Figure 6 The connecting portion 31 includes a support member 311 connected to four hanging members 22 along the diagonal direction of the stone slab 4. A corner joint 312 is installed at one end of the support member 311 away from the fixing member 21, and the corner joint 312 is connected to the corner of the stone slab 4.

[0042] During specific operation, after the four stone slabs 4 are installed on the corresponding hanging parts 22, the four support members 311 are connected to the corresponding four hanging parts 22 in sequence by bolts or welding. The support members 311 are rod-shaped or plate-shaped structures. At this time, the corner joints 312 are located at the corners of the stone slab 4 through the support members 311. The corner joints 312 can be plate-shaped or frame-shaped structures. The corner joints 312 are fixedly connected to the stone slab 4 through back bolts. The corner joints 312 cooperate with the hanging parts 22 to achieve two-point connection of the stone slab 4, and the connection points are distributed along the diagonal of the stone slab 4, which effectively improves the stone slab 4. The stability of the connection between the hanging parts 22 and the stone slabs 4 is improved. After the corner joints 312 are connected to the stone slabs 4, their overall length exceeds the stone slabs, and the exceeding length is half of the gap between the two stone slabs 4. When the next four-in-one installation structure is installed, the two corner joints 312 at the lower end of the upper installation structure abut against the two corner joints 312 at the upper end of the lower installation structure, thereby realizing the overall force balance function of the stone slabs 4 on the multi-layer four-in-one structure, and providing each stone slab 4 with a support point other than the hanging parts 22, thereby improving the stability of the stone slab 4 after installation.

[0043] See Figure 2 、 Figure 5 and Figure 6 The locking portion 32 includes locking seats 321 respectively installed on four supporting members 311, and a connecting member 322 is commonly connected between two adjacent locking seats 321.

[0044] During specific work, after the support member 311 and the corner member 312 are connected to the stone slab 4 and the hanging member 22, four whole connecting members 322 are selected. The whole connecting member 322 can be rod-shaped or plate-shaped. The whole connecting member 322 is fixedly connected between two adjacent locking seats 321 by bolts. The four whole connecting members 322 fixedly connected to the four locking seats 321 can indirectly connect the four stone slabs 4 as a whole through the support member 311, ensuring that the four stone slabs 4 are subjected to balanced force, thereby improving the stability of the connection between the four hanging members 22 and the four stone slabs 4.

[0045] After the four slates 4 on one fixing piece 21 are installed, multiple fixing pieces 21 are installed on the horizontal keel 1 in a horizontal direction, and the steps of installing the four slates 4 are repeated. Then, multiple fixing pieces 21 are installed on the horizontal keel 1 of each layer from bottom to top, and the steps of installing the four slates 4 are repeated until all the slates to be installed are installed to form a curtain wall (such as Figure 8 and Figure 9 ), the installation is complete.
