Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a device for connecting new types of ceramic bricks and its construction process. Background Technology

[0002] In existing technologies, terracotta bricks, as a new type of decorative material, have been widely used in recent years for building facade decoration, such as curtain walls, due to their unique humanistic and artistic charm, natural and bright colors, simple and durable texture, and superior performance. The raw material for terracotta bricks is natural clay, without any added components. They are manufactured through extrusion molding and high-temperature firing. Terracotta brick curtain walls endow buildings with a dignified and strong artistic aesthetic. The product has excellent durability, and its colors remain vibrant over time, bringing vitality to the curtain wall.

[0003] However, in the actual construction of terracotta brick curtain walls, the connection and fixing between the terracotta bricks and the main structure has always been a critical aspect affecting construction quality and curtain wall safety. Traditional terracotta brick connection methods mostly use tie members formed by bending steel bars. The inner end of the tie member is fixedly connected to the cast concrete wall or other types of masonry wall, and the outer end is tied or sleeved to the vertical steel bars on the terracotta wall.

[0004] However, this method still has shortcomings. The inner end of the tie rod is usually connected to the concrete wall or other types of masonry wall by pre-embedding or post-installation anchoring, and the installation height is usually preset according to the theoretical number of courses. However, during the construction of terracotta brick curtain walls, due to factors such as errors in the course marking rod, uneven mortar thickness, brick size deviation, and differences in specifications between terracotta bricks and other types of blocks on the inner side, the actual masonry height often deviates from the design height. This preset method cannot adapt to the cumulative height error and mismatch between the inner and outer block specifications in actual construction, which can easily cause misalignment between the tie rod and the mortar joint of the terracotta brick, affecting not only the aesthetics but also weakening the tie effect. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a device and construction process for tying new types of ceramic bricks, in order to solve the technical problems in the prior art such as the fixed height of the tie member and the inability to adjust it, which leads to misalignment with the mortar joint of the ceramic brick.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows: In a first aspect, a device for tying novel terracotta bricks includes a reinforcing bar tying assembly and a fixing seat assembly. The reinforcing bar tying assembly is fixed to the inner wall body via the fixing seat assembly and can be adjusted vertically via the fixing seat assembly, and can be locked after adjustment to a specified height. The outer end of the reinforcing bar tying assembly has a connecting hole that matches the vertical reinforcing bars on the terracotta brick wall. The vertical reinforcing bars pass through the connecting hole.

[0007] Furthermore, the fixing seat assembly includes a fixing seat body, a mechanical anchor bolt, and an anchor bolt nut. The fixing seat body has an L-shaped structure. A strip-shaped adjustment hole is provided on the fixing seat body to cooperate with the mechanical anchor bolt. The inner end of the mechanical anchor bolt is fixed to the inner wall body, and the outer end passes through the strip-shaped adjustment hole and is threadedly connected to the anchor bolt nut.

[0008] Furthermore, the main body of the fixing seat is divided into a vertical fixing surface and a horizontal connecting surface. The fixing surface is in contact with the main body of the inner wall. The strip-shaped adjustment hole is formed on the fixing surface.

[0009] Furthermore, the rebar tie assembly includes a galvanized tie plate, a bolt, and a tie plate nut. The inner end of the galvanized tie plate is connected to the connecting surface of the fixing base body via the bolt and nut. The connecting hole is located on the outer end of the galvanized tie plate.

[0010] Furthermore, washers are provided between the bolts, pull tab nuts, and galvanized pull tabs.

[0011] Secondly, a construction technique for bonding new types of ceramic bricks, with the following specific steps: Step S1, Detailing and Brick Laying: Based on the main outline of the building's interior walls, confirm the size and type of terracotta bricks, and use BIM brick laying technology for preliminary detailing.

[0012] Step S2: Measurement and Laying Out. Before laying the terracotta bricks, use the bottom layer axis positioning nails as a reference to pull out the foundation guideline. The direction of pulling the foundation guideline is parallel to the horizontal plane. Hang a plumb line along the foundation guideline to project the axis onto the foundation surface. Then, based on the axis, mark out the longitudinal and transverse wall edge lines to determine the positions of doors and windows.

[0013] Step S3: Erect bricklaying rods. Place multiple bricklaying rods at wall corners, junctions of interior and exterior walls, and stairwells. Mark the laying height, mortar joint thickness, and elevation positions of door and window openings, lintels, and floor slab components on each rod. Stretch elevation lines between the bricklaying rods and lay the bricks layer by layer according to the elevation lines.

[0014] Step S4: Construction of the inner steel reinforcement frame. Vertical steel bars are inserted into the holes of the terracotta bricks at the designed intervals. The vertical steel bars are tied and fixed to the connecting steel bars reserved on the foundation ground and the top structure.

[0015] Step S5, masonry construction, begin masonry work from the corner or positioning point. During masonry, the thickness of the horizontal mortar joints and the width of the vertical mortar joints in the terracotta brick wall should be controlled between 5 and 10 mm.

[0016] Step S6, horizontal connection: When laying terracotta bricks to a specified height, multiple terracotta brick connection devices are spaced apart horizontally. The fixing seat assembly in each terracotta brick connection device is fixed to the inner wall body. The connecting hole on the outer end of the steel reinforcement connection assembly is connected to the vertical steel reinforcement set in step S4, and then moved down onto the laid terracotta bricks. The inner end is connected and fixed to the fixing seat body, achieving a horizontal connection with the terracotta brick wall.

[0017] Step S7: Grouting and joint cleaning. After the terracotta bricks are laid and the mortar has reached its initial setting strength, grouting is performed. After the operation is completed, wipe the brick surface clean with a sponge or soft cloth.

[0018] Furthermore, in step S6, a 6 mm horizontal tie bar is installed at the designed interval along the height of the terracotta wall and placed in the horizontal mortar joint. The horizontal tie bar is tied to the vertical dowel bar.

[0019] Furthermore, in step S3, the length of the elevation guideline is less than 5m; if it is greater than 5m, a waist line is set at the middle position. The elevation guideline is tensioned using nylon rope.

[0020] Furthermore, in step S4, holes are drilled in the foundation ground to create the necessary insertion holes for the connecting reinforcing bars. The connecting reinforcing bars are then inserted into the insertion holes. The bottom of the vertical reinforcing bars is secured to the connecting reinforcing bars with steel wire.

[0021] Furthermore, multiple terracotta brick tying devices located on the same horizontal plane constitute a group of terracotta brick tying units. Multiple groups of terracotta brick tying units are spaced apart along the height direction of the terracotta brick wall, and the vertical distance between adjacent groups of terracotta brick tying units is determined according to design calculations.

[0022] Compared with the prior art, the present invention has the following advantages: This invention, through the cooperation of the strip-shaped adjustment holes on the fixed base assembly and the mechanical anchor bolts, enables the flexible vertical movement and adjustment of the steel reinforcement tie assembly. It can effectively compensate for the cumulative height error and mortar joint misalignment caused by factors such as the marking error of the brick gauge rod, uneven mortar thickness, brick size deviation, and the difference in specifications between the ceramic bricks and other types of blocks on the inner side during construction. This ensures that the galvanized tie plate used for tying is always precisely aligned with the mortar joint of the ceramic bricks, thus guaranteeing both the aesthetics of the curtain wall and the reliability of the tie.

Detailed Implementation

[0025] In the description of this invention, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] like Figure 1 As shown, a device for tying up new types of terracotta bricks is installed on an inner wall body 100 or a brick wall to tie up the terracotta brick wall used for exterior decoration, thereby ensuring the stability and safety of the terracotta bricks during long-term use. The inner wall body is a concrete wall or other types of masonry wall. The tying device includes a steel bar tying component 1 and a fixing seat component 2. The steel bar tying component 1 is fixed to the inner wall body 100 by the fixing seat component 2, and can be adjusted vertically by the fixing seat component 2, locking after adjustment to a specified height, thus meeting the tying requirements of terracotta brick walls with different mortar joint heights. The outer end of the steel bar tying component 1 has a connecting hole for connecting with vertical steel bars 9 on the terracotta brick wall. The vertical steel bars 9 pass through the connecting hole. Effective tying of the terracotta bricks is achieved through the cooperation of the vertical steel bars 9 and the steel bar tying component.

[0028] Specifically, the fixing bracket assembly 2 includes a fixing bracket body 3, a mechanical anchor bolt, and an anchor bolt nut 4. The mechanical anchor bolt is fixed to the inner wall body 100. The fixing bracket body 3 has an L-shaped structure, divided into a vertical fixing surface and a horizontal connecting surface. The fixing surface has a strip-shaped adjustment hole 5 that mates with the mechanical anchor bolt. During installation, the fixing surface is in contact with the inner wall body 100. The inner end of the mechanical anchor bolt is fixed to the inner wall body 100, and the outer end passes through the strip-shaped adjustment hole 5 and is threadedly connected to the anchor bolt nut 4. By tightening the anchor bolt nut 4, the fixing bracket body 3 can be fixed to the inner wall body 100.

[0029] In this embodiment, the fixing seat body 3 adopts an angle bracket, and the mechanical anchor bolt adopts a rear-expanded mechanical anchor bolt.

[0030] The rebar tie assembly 1 includes a galvanized tie plate 6, a bolt 7, and a tie plate nut 8. One end of the galvanized tie plate 6 is connected to the connecting surface of the fixing base body 3, and the other end extends outward and has the connecting hole. Specifically, a bolt 7 hole is provided on the horizontal connecting surface, and a corresponding mounting through hole is provided at the connecting end of the galvanized tie plate 6. The bolt 7 passes through the mounting through hole and the bolt 7 hole and is threadedly connected to the tie plate nut 8, thereby detachably fixing the galvanized tie plate 6 to the horizontal connecting surface of the fixing base body 3. This detachable connection method facilitates adjustment of the angle and position of the galvanized tie plate 6 according to actual needs during installation, and also facilitates later maintenance or replacement of the device.

[0031] In this embodiment, washers are provided between the bolt 7, the pull tab nut 8, and the galvanized pull tab 6 to increase the friction of the connection and prevent the bolt 7 from loosening.

[0032] like Figure 2 As shown, a construction process for bonding new types of ceramic bricks includes the following specific steps: Step S1, Detailing and Brick Laying: Based on the outline of the building's interior walls (100mm), confirm the size and type of terracotta bricks, and use BIM brick laying technology for preliminary detailing. Control the mortar joint width between adjacent terracotta bricks within the range of 5-6mm.

[0033] Step S2: Measurement and layout. Before laying the terracotta bricks, use the bottom axis positioning nails as a reference to draw a foundation guideline. The direction of the foundation guideline is parallel to the horizontal plane. Hang a plumb line along the foundation guideline to project the axis onto the foundation surface (i.e., the exterior facade of the main interior wall 100). Then, based on the axis, mark the longitudinal and transverse wall edges to determine the positions of doors and windows. Using a theodolite and plumb line, transfer each axis to the floor level, mark the wall edges, and mark the positions of doors and windows.

[0034] Step S3: Erect bricklaying guides. Place multiple bricklaying guides at wall corners, junctions of interior and exterior walls, stairwells, and areas with significant wall variations. The distance between adjacent bricklaying guides should be less than 10 meters. Each bricklaying guide is marked with lines indicating the height of each terracotta brick, the thickness of the mortar joints, and the elevation positions of floors, door and window openings, lintels, ring beams, floor slabs, and beam bottoms. Lay elevation guides between the bricklaying guides and construct the bricklaying layer by layer according to these guides.

[0035] Step S4: Construction of the inner steel reinforcement frame. Vertical steel bars are inserted into the holes of the terracotta bricks at the designed intervals. The vertical steel bars 9 are tied and fixed to the connecting steel bars reserved on the foundation ground and the top structure.

[0036] Specifically, holes are drilled in the foundation ground and top floor slab areas to create the necessary insertion holes for the connecting reinforcing bars. The connecting reinforcing bars are then inserted into these holes. Both ends of the vertical reinforcing bar 9 are secured to the corresponding two connecting reinforcing bars using steel wires to ensure the verticality and stability of the vertical reinforcing bar 9 during use.

[0037] Step S5, bricklaying: Begin bricklaying from the corner or positioning point. During bricklaying, the thickness of the horizontal mortar joints and the width of the vertical mortar joints in the terracotta brick wall should be controlled between 5 and 10 mm. The horizontal mortar joints are controlled by the mortar joint thickness lines drawn on the bricklaying gauge, the verticality is controlled by a plumb line and a hanging plumb line, and the flatness of the wall surface is controlled by hanging lines at the two corners.

[0038] In this embodiment, the thickness of the horizontal mortar joints is 10mm, and the width of the vertical mortar joints is 5mm. Both horizontal and vertical mortar joints are filled with mortar, and the mortar fullness of both horizontal and vertical joints must not be less than 90%. The terracotta brick blocks are laid using double-sided mortar joints. When it is necessary to move or knock over a block that has already been laid, mortar should be reapplied and the block re-laid. The flatness and verticality of the wall surface, as well as the thickness and fullness of the mortar joints, should be checked regularly, and any deviations should be corrected.

[0039] In this embodiment, during the masonry process, a self-made φ8 plain round steel bar tool is placed on the outside of the mortar joint of the masonry block to prevent mortar from flowing and contaminating the wall surface.

[0040] Step S6, horizontal connection: When laying terracotta bricks to a specified height, multiple terracotta brick connection devices are spaced apart horizontally. The fixing seat body 3 of each terracotta brick connection device is fixed to the inner wall body 100 by mechanical anchors. The connecting hole on the outer end of the steel bar connection assembly 1 is connected to the vertical steel bar 9 set in step S4, and then lowered onto the laid terracotta bricks. The inner end is connected and fixed to the fixing seat body 3, achieving a horizontal connection with the terracotta brick wall.

[0041] Furthermore, 10 horizontal tie bars of ⌀6 mm are installed along the height of the terracotta wall at design intervals (one bar every 16 brick courses in some embodiments), placed in the horizontal mortar joints, and the horizontal tie bars are tied to the vertical dowel bars.

[0042] In this embodiment, multiple ceramic brick tying devices located on the same horizontal plane constitute a group of ceramic brick tying units. Multiple groups of ceramic brick tying units are spaced apart along the height direction of the ceramic brick wall, and the vertical distance between two adjacent groups of ceramic brick tying units is determined according to design calculations (in some embodiments, it matches the height of 16 brick courses marked on the brick gauge rod).

[0043] Step S7: Grouting and Joint Cleaning. After the terracotta bricks are laid and the mortar has reached its initial setting strength, grouting is performed. The grout thickness should be 3-5mm recessed from the surface of the brick. After completion, wipe the brick surface clean with a sponge or soft cloth.

[0044] In this embodiment, in step S1, the bricklaying construction needs to proceed from both sides of the building's centerline. The bottom bricklaying should be completed before formal construction to ensure symmetry and aesthetics. During the detailed design, the connection and transition with the surrounding aluminum panel curtain wall, glass curtain wall, and stone curtain wall will be considered—for example, aluminum single-panel cladding will be used at the upper and lower joints with the aluminum panel curtain wall, while ensuring that the whole module of terracotta bricks is adjusted in place to minimize raw material waste.

[0045] Furthermore, in step S3, the length of the elevation guideline is less than 5m. If it is greater than 5m, a waist line is set in the middle to avoid the effects of sagging and wind. The elevation guideline is tensioned using nylon rope to reduce errors. The elevation values ​​measured with a level are marked on the structural column reinforcement with red paint. The gauge rods are then tied to the structural column reinforcement according to the markings. After tying, a dedicated quality inspection personnel conduct a full inspection and calibration.

[0046] After each floor is completed, check the axial dimensions and elevation of the wall. Deviations in axial dimensions and elevation within the allowable range can be corrected on the floor slab. The masonry height should be controlled according to different conditions such as air temperature, wind pressure, wall location, and block material. Under normal temperature conditions, the daily masonry height should be controlled within 1.8m.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
