Description

Technical Field

[0001] This invention relates to a method for connecting an antique-style exposed brick wall with a modern structure. Background Technology

[0002] With increasing awareness of preserving the traditional features of historic districts, the architectural styles of modern buildings within these districts need to be in harmony with the original character of the area. Therefore, most of these buildings adopt antique-style facades. Among them, exposed brick walls are the main facade form of Shikumen buildings in Shanghai's historic districts.

[0003] To achieve exposed brick facades in modern buildings, there are currently two main methods:

[0004] Method 1: Similar to traditional buildings, exposed brick walls are used as the building envelope. However, exposed brick walls have poor waterproof and thermal insulation properties, making it difficult to meet the functional requirements of modern buildings.

[0005] Method 2: Directly constructing exposed brick walls on the outer side of the building. This construction method does not connect the exposed brick walls with the modern building structure. The exposed brick walls serve only as an outer shell of the building, and their excessive height-to-width ratio poses a risk of collapse and a great safety hazard.

[0006] Meanwhile, when using the above two methods, the exposed brick walls in complex facade shapes such as gables and arches can only be achieved by on-site masonry, which makes it difficult to control the masonry quality and requires a lot of manpower. Summary of the Invention

[0007] The purpose of this invention is to provide a method for connecting antique-style exposed brick walls with modern structures.

[0008] To solve the above problems, the present invention provides a method for connecting an antique-style exposed brick wall with a modern structure, comprising: welding tie bars to galvanized steel plates to form a tie device between the exposed brick wall and the masonry wall;

[0009] When constructing a masonry wall, tie devices are installed on the masonry wall at preset intervals. The tie bars of each tie device are placed in the mortar joints of the masonry wall, and galvanized steel plates are placed on the inner wall surface of the masonry wall.

[0010] Add a ring beam inside the masonry wall at the height of the pediment and arch on the exterior facade between the tie devices, and set concrete cantilever lugs on the outside of the ring beam.

[0011] After the masonry wall is fully constructed, apply a cement mortar leveling layer to the surface of the masonry wall, and then apply a waterproof coating to the surface of the cement mortar leveling layer.

[0012] After the waterproof coating has dried completely, longitudinal and transverse light steel keels are installed on the outside of the waterproof coating, and an insulation layer is filled between the longitudinal and transverse light steel keels.

[0013] The waterproof and breathable membrane is fixed to the longitudinal and transverse light steel keel with nails on the outside of the rock wool insulation layer. At the nail locations, the waterproof and breathable membrane is repaired with flexible butyl waterproof tape.

[0014] A double-layer galvanized steel wire mesh cement mortar plaster layer is applied over the waterproof and breathable membrane.

[0015] An antique-style exposed brick wall is built on one side of a double-layer galvanized steel wire mesh cement mortar plaster layer. The antique-style exposed brick wall is connected to the masonry wall as a whole by tie bars. When the exposed brick wall is built to the position of the facade decoration of the pediment and arch, the prefabricated pediment and arch are connected to the concrete cantilever lugs by expansion bolts.

[0016] Furthermore, in the above method, the tie bar is welded to the galvanized steel plate to form a tie device between the fair-faced brick wall and the masonry wall, including:

[0017] One end of the tie bar is perpendicularly connected to one side of the galvanized steel plate.

[0018] Furthermore, in the above method, the tie-up devices are installed on the masonry wall at preset intervals, including:

[0019] Tie-fitting devices are installed on the masonry wall to connect with the antique-style exposed brick wall, with a vertical spacing of 480mm and a horizontal spacing of 1800mm.

[0020] Furthermore, in the above method, when applying waterproof coating to the leveling layer surface, the waterproof coating is JSA-101 waterproof coating.

[0021] Furthermore, in the above method, the insulation layer is a rock wool insulation layer.

[0022] Furthermore, in the above method, the longitudinal and transverse light steel keels are C50 light steel keels.

[0023] Furthermore, in the above method, the wire mesh of the double-layer galvanized steel wire mesh cement mortar plaster layer has a wire diameter of 6 mm and a spacing of 200 mm.

[0024] Furthermore, in the above method, a double-layer galvanized steel wire mesh cement mortar plaster layer is applied outside the waterproof and breathable membrane, including:

[0025] The wire mesh is fixed to the longitudinal and transverse light steel keels using nails.

[0026] Furthermore, in the above method, constructing an antique-style exposed brick wall on one side of the double-layer galvanized steel wire mesh cement mortar plaster layer includes:

[0027] The antique-style exposed brick wall is bonded to the double-layer galvanized steel wire mesh cement mortar plaster layer through a cement mortar bonding layer.

[0028] Furthermore, in the above method, after connecting the precast pediments and arches to the concrete cantilever lugs using expansion bolts, the following steps are also included:

[0029] The remaining areas outside the double-layer galvanized steel wire mesh cement mortar plaster layer at the same height as the gable and arch are constructed using pre-sized brick slabs.

[0030] Compared with existing technologies, the connection structure between the antique-style exposed brick wall and the modern structure described in this invention uses a tie device to connect the exposed brick wall and the masonry wall into a whole, reducing the height-to-width ratio of the exposed brick wall and improving its safety. Simultaneously, the connection structure between the antique-style exposed brick wall and the modern structure described in this invention allows for the prefabrication of complex exterior decorations on the antique-style exposed brick wall facade, improving construction efficiency while ensuring decorative effects. This invention achieves the following innovations:

[0031] 1) The connection structure between the antique-style exposed brick wall and the modern structure described in this invention uses a tie-down device to connect the antique-style exposed brick wall and the modern structure into a whole.

[0032] 2) The tie device described in this invention is made of galvanized steel plate and tie bar welded together. The galvanized steel plate is placed inside the masonry wall and the tie bar is placed in the mortar joint of the masonry wall. Compared with the general method of using only tie bars and relying on the anchoring of the tie bars with the mortar joint to achieve tie, the tie effect of this method is more stable and will not cause the brick wall to become unstable due to the weak anchoring force of the steel bars in the mortar joint.

[0033] 3) The connection structure between the antique-style exposed brick wall and the modern structure described in this invention supports the use of prefabricated components for complex decorations such as gables and arches on the exterior facade of the exposed brick wall, and reliably connects them to the internal modern structure through concrete cantilevered ears.

[0034] 4) The connection structure between the antique-style exposed brick wall and the modern structure described in this invention improves the waterproof performance of the joint by setting two waterproof layers on the outside of the masonry wall and the outside of the rock surface respectively.

[0035] The connection structure between the antique-style exposed brick wall and the modern structure described in this invention allows the modern structure to have the exterior appearance of antique exposed brick, while also possessing the good thermal insulation and waterproofing functions of a modern building envelope. Furthermore, for complex pediments, arches, and other decorative elements on the exposed brick wall facade, prefabrication can be adopted, avoiding the problems of difficult quality control and high labor consumption during on-site construction of complex decorative elements on exposed brick walls. Thus, the antique effect of the modern building facade can be achieved efficiently and with high quality. Attached Figure Description

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] To address the problems existing in the two current methods of using antique-style exposed brick walls for facades in modern buildings, this invention proposes a connection structure and construction method for antique-style exposed brick walls and modern structures. This method connects the exposed brick walls to the structural system of modern buildings, increasing the integrity of the exposed brick walls and enabling the prefabrication of complex gables and arches. This invention achieves the connection between antique-style exposed brick walls and modern structures, increasing their overall integrity, reducing the height-to-width ratio of the exposed brick walls, and improving their safety performance. Furthermore, in areas with complex facade designs such as gables and arches, prefabricated gable and arch components can be used, ensuring both decorative effect and improved on-site construction efficiency.

[0046] The connection node construction between the antique-style exposed brick wall and the modern structure described in this invention is as follows: Figure 8 As shown:

[0047] Among them, 1 is a 50×50×5 galvanized steel plate, 2 is a φ6 tie bar, and 2 and 1 are welded together to form a tie device 21; 4 is a structural cantilever, 5 is a custom-made brick or precast gable or arch component, 6 is a 20mm cement mortar leveling layer, 7 is JSA-101 waterproof coating, 8 is a light steel keel, 9 is a rock wool insulation layer filled between the longitudinal and transverse keels, 10 is a waterproof and breathable membrane, 11 is a double-layer galvanized steel wire mesh cement mortar plastering layer, 12 is a cement mortar bonding layer, 15 is a fair-faced brick wall, 13 is a masonry wall, and 14 is a ring beam.

[0048] The above-mentioned connection structure between antique-style exposed brick walls and modern structures can effectively connect exposed brick walls and modern structures, improve the integrity of exposed brick walls, reduce the height-to-width ratio of exposed brick walls, and improve their safety performance. At the same time, in locations with complex facade shapes such as gables and arches, prefabricated gable and arch components can be connected with concrete cantilevered ears, which can improve on-site construction efficiency while ensuring the finishing effect.

[0049] like Figures 1 to 8 As shown, the present invention provides a method for connecting an antique-style exposed brick wall with a modern structure, comprising:

[0050] like Figure 1 As shown, the first step is to weld the tie bar 2 to the galvanized steel plate 1 to form a tie device 21 between the fair-faced brick wall and the masonry wall;

[0051] Preferably, one end of the tie bar 2 is perpendicularly connected to one side of the galvanized steel plate 1;

[0052] like Figure 2 As shown, the second step is to build the masonry wall 13. When building the masonry wall 13, tie devices 21 are set on the masonry wall 13 at preset intervals. The tie bars 2 of each tie device 21 are set in the mortar joints of the masonry wall, and the galvanized steel plate 1 is set on the inner wall surface of the masonry wall.

[0053] Preferably, a tie device 21 for connecting with the antique-style exposed brick wall is provided on the masonry wall 13 at a vertical spacing of 480mm and a horizontal spacing of 1800mm.

[0054] like Figure 3 As shown, the third step is to add a ring beam 14 inside the masonry wall 13 at the height of the gable and arch 5 on the exterior facade between the tie devices 21, and to set concrete cantilever 4 on the outside of the ring beam 14.

[0055] like Figure 4 As shown, the fourth step: after the masonry wall 13 is fully constructed, a 20mm cement mortar leveling layer 6 is applied to the surface of the masonry wall 13, and then a waterproof coating 7 is applied to the surface of the leveling layer 6.

[0056] Preferably, the waterproof coating 7 is JSA-101 waterproof coating;

[0057] like Figure 5 As shown, the fifth step is to install longitudinal and transverse light steel keels 8 on the outside of the waterproof coating 7 after the waterproof coating 7 has dried completely, and fill the space between the longitudinal and transverse light steel keels 8 with rock wool insulation layer 9.

[0058] Preferably, the longitudinal and transverse light steel keels 8 are C50 light steel keels;

[0059] like Figure 6 As shown, step six: use nails to fix the waterproof and breathable membrane 10 to the longitudinal and transverse light steel keel 8 on the outside of the rock wool insulation layer 9. At the nail positions, use flexible butyl waterproof tape to repair the waterproof and breathable membrane.

[0060] like Figure 7 As shown, step seven: On the outside of the waterproof and breathable membrane 10, construct a double-layer galvanized steel wire mesh cement mortar plaster layer 11;

[0061] Preferably, the wire mesh of the double-layer galvanized steel wire mesh cement mortar plaster layer 11 has a wire diameter of 6 mm and a spacing of 200 mm. The wire mesh is fixed to the longitudinal and transverse light steel keel 8 by nails.

[0062] like Figure 8 As shown, step eight: Construct an antique-style exposed brick wall 15 on one side of the double-layer galvanized steel wire mesh cement mortar plaster layer 11, and connect the antique-style exposed brick wall 15 to the masonry wall 13 as a whole through tie bars 2.

[0063] Preferably, the antique-style exposed brick wall 15 and the double-layer galvanized steel wire mesh cement mortar plaster layer 11 are bonded together by a cement mortar bonding layer 12.

[0064] When the exposed brick wall is built to the position of the pediment and arch facade decoration, the precast pediment and arch 5 are connected to the concrete cantilever 4 by expansion bolts. The remaining positions on the outside of the double-layer galvanized steel wire mesh cement mortar plaster layer 11 at the same height as the pediment and arch 5 are built with bricks of a preset size.

[0065] The present invention describes a connection structure between an antique-style exposed brick wall and a modern structure. This structure uses a tie-down device to connect the exposed brick wall and the masonry wall as a whole, reducing the height-to-width ratio of the exposed brick wall and improving its safety. Simultaneously, this connection structure allows for the prefabrication of complex exterior decorations on the antique-style exposed brick wall, improving construction efficiency while ensuring decorative effects. The present invention achieves the following innovations:

[0067] 2) The tie device described in this invention is made of galvanized steel plate and tie bar welded together. The galvanized steel plate is placed inside the masonry wall and the tie bar is placed in the mortar joint of the masonry wall. Compared with the general method of using only tie bars and relying on the anchoring of the tie bars with the mortar joint to achieve tie, the tie effect of this method is more stable and will not cause the brick wall to become unstable due to the weak anchoring force of the steel bars in the mortar joint.

[0068] 3) The connection structure between the antique-style exposed brick wall and the modern structure described in this invention supports the use of prefabricated components for complex decorations such as gables and arches on the exterior facade of the exposed brick wall, and reliably connects them to the internal modern structure through concrete cantilevered ears.

[0069] 4) The connection structure between the antique-style exposed brick wall and the modern structure described in this invention improves the waterproof performance of the joint by setting two waterproof layers on the outside of the masonry wall and the outside of the rock surface respectively.

[0070] The connection structure between the antique-style exposed brick wall and the modern structure described in this invention allows the modern structure to have the exterior appearance of antique exposed brick, while also possessing the good thermal insulation and waterproofing functions of a modern building envelope. Furthermore, for complex pediments, arches, and other decorative elements on the exposed brick wall facade, prefabrication can be adopted, avoiding the problems of difficult quality control and high labor consumption during on-site construction of complex decorative elements on exposed brick walls. Thus, the antique effect of the modern building facade can be achieved efficiently and with high quality.
