Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dry hanging decorative bricks, in particular to a dry hanging decorative brick unit module and an installation structure thereof. BACKGROUND

[0002] Decorative bricks are widely used as building facade decoration materials due to their unique texture and good durability. Dry hanging installation is a common construction method.

[0003] In traditional technology, decorative bricks are usually installed one by one, for example, vertically hung on the reinforcing bar, or horizontally inserted into the T-shaped track, or embedded in the upper and lower clamping grooves. However, the traditional dry hanging installation method has obvious defects when applied to large-area facade decoration: at the construction site, decorative bricks need to be installed one by one, the installation efficiency is low, and after installation, there are a large number of joints, which are very labor-intensive to fill with adhesive or jointing agent, resulting in low overall construction efficiency and high labor cost.

[0004] Therefore, we propose a dry hanging decorative brick unit module and an installation structure thereof. SUMMARY

[0005] The present application provides a dry hanging decorative brick unit module and an installation structure thereof, which solves the technical problems of low construction efficiency and high labor cost of existing decorative bricks.

[0006] To achieve the above purpose, the present application is realized by the following technical scheme:

[0007] A dry hanging decorative brick unit module is characterized by being composed of a plurality of decorative bricks.

[0008] Further, the gap between adjacent decorative bricks is filled with adhesive to fix the adjacent decorative bricks.

[0009] Alternatively, an adhesive layer is formed on the back of the unit module as a whole to fix the adjacent decorative bricks, and the gap between the adjacent decorative bricks is filled with a pointing agent.

[0010] Further, the decorative bricks are split bricks or clay bricks.

[0011] An installation structure of a dry hanging decorative brick unit module is characterized by being composed of a plurality of decorative bricks, and the dry hanging decorative brick unit module is supported on the load-bearing beam of a curtain wall, and the curtain wall is installed on the facade of a building.

[0012] Furthermore, the decorative bricks of the dry-hanging decorative brick unit module are arranged in a longitudinal laying structure. The dry-hanging decorative brick unit module includes a first module, and a second module is provided on both sides of the first module. The left and right sides of the first module are provided with convex and concave structures. The second module has a concave and convex fitting structure on at least one side facing the first module. The convex and concave structure of the first module and the concave and convex fitting structure of the second mold hole are interlocked and penetrated by vertical inserts. The inserts are fixedly connected to the load-bearing beam.

[0013] Among them, the decorative bricks forming the protruding parts on the sides of the first module and the second module are respectively the first side decorative bricks and the second side decorative bricks, and the rest are the main decorative bricks;

[0014] The first side decorative brick has a through hole for a side insert bar that runs vertically through it, and the second side decorative brick has a U-shaped opening that runs vertically through it. One side of the opening of the U-shaped opening faces inward. The first side decorative brick is fitted onto the insert bar through the through hole, and the second side decorative brick is fastened onto the insert bar through the U-shaped opening. The second side decorative brick is fixedly connected to the curtain wall or the exterior facade of the building by locking bolts.

[0015] Furthermore, the U-shaped opening is equipped with a first anti-detachment structure, which includes a pair of elastic locking blocks.

[0016] Furthermore, the U-shaped opening is equipped with a second anti-detachment structure, which includes a guide sleeve, a hinge ear, a spring, a connecting rod, a plug rod, and a guide rail. The guide sleeve is disposed in the bolt hole of the second decorative brick through which the locking bolt passes. The hinge ear and the spring are disposed in the guide sleeve. The two ends of the connecting rod are pivotally connected to the hinge ear and the plug rod, respectively. The plug rod is slidably disposed in the track groove of the guide rail. The guide rail is pre-embedded in the second side decorative brick and its track groove opening communicates with the U-shaped opening. The two ends of the guide sleeve are respectively equipped with an outer limiting nut and an inner limiting nut. The two ends of the spring abut against the hinge ear and the inner limiting nut, respectively. The screw of the locking bolt passes through the hinge ear and the stepped surface of its screw presses the hinge ear onto the spring.

[0017] The guide sleeve has a guide groove on its side, and the hinge ear seat and the end of the insertion rod are respectively provided with a pair of supporting ears. One end of the connecting rod is pivotally connected to a pair of supporting ears of the hinge ear seat passing through the guide groove, and the other end is pivotally connected to a pair of supporting ears of the insertion rod.

[0018] Preferably, the outer wall of the guide sleeve is provided with a first anti-detachment nail, and the outer wall of the protective sleeve is provided with a second anti-detachment nail, both the first and second anti-detachment nails being embedded in the second side decorative brick.

[0019] This invention provides a dry-hanging decorative brick unit module and its installation structure, which has the following beneficial effects:

[0020] 1. Before producing decorative bricks, technicians will go to the site to measure and arrange the actual dimensions of the facade. After the decorative bricks are produced, they will be poured in modular form according to the layout and completed in batches by area. The modular bricks will be transported to the site for direct installation without the need for on-site cutting and pasting. This avoids the need for on-site installation of individual bricks and the loss of workers caused by excessive cutting and cross-construction, which greatly improves the on-site installation efficiency, reduces the cost of construction personnel, and results in a relatively lower cost.

[0021] 2. In existing technologies, when a decorative brick is damaged and needs to be replaced, it is often necessary to move multiple surrounding bricks or even the entire string of bricks. The disassembly and reassembly process is complicated and seriously affects the convenience of later maintenance. Single unit modules also have this technical problem. Therefore, the unit module made of terracotta bricks is designed as a first module and a second module. The first module adopts a rib-hanging structure, and the second module is fastened with the rib and connected to the curtain wall / facade with bolts for detachment. The second modules on both sides can be removed, the ribs can be loosened and moved up or down to form a nested structure, and the first module can be removed for easy replacement and maintenance.

[0039] Example 1

[0040] A dry-hanging decorative brick unit module is composed of several decorative bricks fixedly connected together. (See attached document.) Figures 1-2 The decorative bricks are made of split bricks, forming dry-hanging split brick unit modules 10'. All split bricks have the same structure. The back of the unit module is filled with C100 cement mortar to form an adhesive layer 12', which is embedded in the gaps between adjacent split bricks. The adhesive layer 12' has the same planar shape as the dry-hanging split brick unit module 10'. The adhesive layer 12' and the part embedded in the gap together form a cement-cast connection structure 12', which fixes all split bricks together. During casting, a fiber mesh can be laid on the surface of the adhesive layer 12', with a stainless steel mesh 13' embedded inside to improve the strength of the adhesive layer 12'. In addition, the gaps between adjacent split bricks can be filled with grout for aesthetic purposes.

[0041] A dovetail groove can be made on the back of the split brick, and the adhesive layer 12' is embedded in the dovetail groove to improve the bonding strength between the two.

[0042] The installation structure of the dry-hanging split brick unit module 10' is as follows:Figure 3 As shown, the dry-hanging split brick unit module 10' is installed on the curtain wall. The curtain wall is mainly composed of vertical keel 14' and horizontal keel 15'. There is a side-mounted T-shaped hanger 16' on the front side of the horizontal keel 15'. The upper and lower ends of the dry-hanging split brick unit module 10' are respectively provided with slots and are inserted and fixed by the T-shaped hanger 16'. Adjacent dry-hanging split brick unit modules 10' are spliced ​​together.

[0043] Example 2

[0044] See attached document Figure 4 The difference between Example 2 and Example 1 is that the decorative bricks used are terracotta bricks, forming a dry-hanging terracotta brick unit module 10". Traditional dry-hanging terracotta bricks have through-holes distributed vertically. Except for the overlapping areas of adjacent unit modules, C100 cement mortar is poured into the other through-holes in the unit module, and the C100 cement mortar is embedded in the gaps between adjacent terracotta bricks to fix all the terracotta bricks together. Reinforcing bars 13” can be inserted into the through-holes where C100 cement mortar is poured to increase strength.

[0045] The dry-hanging terracotta brick unit module 10” can adopt the installation structure of Example 1, which also requires slots to be cut at the top and bottom of the unit module.

[0046] Example 3

[0047] See attached document Figures 5-8 An improved terracotta brick unit module installation structure is provided. The improved terracotta brick unit module 10 is composed of several terracotta bricks fixed together. Several improved terracotta brick unit modules 10 (only 2 are shown in the figure, and more can be added according to the actual design drawings) are assembled and supported on the load-bearing beam 31 of the curtain wall, and the curtain wall is installed on the exterior facade of the building.

[0048] In this embodiment, the gaps between adjacent terracotta bricks are filled with adhesive to secure them together. The improved terracotta brick unit module 10 comprises several terracotta bricks arranged in a longitudinal laying structure. The improved terracotta brick unit module 10 includes a first module 10-1, with second modules 10-2 on both sides of the first module 10-1. The left and right sides of the first module 10-1 have convex-concave structures, and the second module 10-2 has a concave-convex fitting structure on at least one side facing the first module 10-1. The convex-concave structure of the first module 10-1 and the concave-convex fitting structure of the second mold hole are interlocked and penetrated by vertical reinforcing bars 32, which are fixedly connected to the supporting beam 31.

[0049] This invention also provides a construction process for an improved terracotta brick unit module, comprising the following steps performed sequentially:

[0050] S1. Curtain wall construction: According to the design drawings, install the curtain wall keel and load-bearing beam 31 in position. The curtain wall structure is not shown in the drawings and is based on existing conventional technology. For example, the keel is fixed to the exterior of the building through adapters and bolts. The connection between the adapter and the exterior can be made by expansion bolts or by pre-embedding steel plates on the exterior. Locking nuts are embedded inside the steel plates. High-strength bolts pass through the adapter and locking nuts for threaded connection. The load-bearing beam 31 can be fixed to the keel by welding or by using bolt and nut assemblies for detachable fixing to the keel.

[0051] S2. Module Installation: Installation follows the principle of "bottom-up, layered construction." According to the drawing numbers, install the reinforcing bars 32 and improved terracotta brick unit modules 10 onto the curtain wall and secure them. After each module is installed, adjust its flatness and verticality promptly. The width of the joints 12 between adjacent modules must be consistent, with a deviation controlled within 2mm. After layered installation is complete, conduct an overall check to ensure that the modules are neatly arranged and accurately positioned.

[0052] S3. Grouting and cleaning: Clean the dust, debris, and loose dust in the joint 12 at the junction of adjacent modules to ensure that the joint 12 is dry and clean. Then, select a grout, filler, or adhesive that matches the color of the terracotta bricks and meets the requirements for weather resistance. Use a special grouting tool to evenly fill the joint 12. During the filling process, ensure that the filler is full and without gaps, and smooth and polish the surface to make the width, flatness, and appearance of the joint 12 consistent with the gap of the main surface.

[0053] Before construction, technicians went to the construction site to conduct comprehensive actual size measurements of the building facade, accurately recording the flatness, verticality, and key node dimensions of the wall surface. Based on the measured data and design drawings, the technicians completed the layout design. First, they determined the layout parameters of the curtain wall structure, including the specifications and selection of the keel, the spacing layout, the horizontal and vertical installation baselines, and the load-bearing range, installation height, and fixing points of the load-bearing beam 31. Second, they determined the layout details of the improved terracotta brick unit module 10, covering the installation coordinates, shape adjustments (to adapt to the facade shape), distribution patterns, and numbering rules of each module, ensuring that the modules and the curtain wall structure are accurately matched.

[0054] Example 4

[0055] Example 4 is an improvement on Example 3, as shown in the appendix. Figures 9-17 The main differences are as follows.

[0056] Among them, the clay bricks forming the protruding parts 11a on the sides of the first module 10-1 and the second module 10-2 are the first side clay brick 11-1 and the second side clay brick 11-2, respectively, and the rest are the main body clay bricks 11-3; the protruding parts 11a of the first side clay brick 11-1 and the second side clay brick 11-2 are provided with through holes running vertically, while the remaining parts of the first side clay brick 11-1 and the second side clay brick 11-2 as well as the main body clay brick 11-3 are not provided with through holes running vertically.

[0057] The first side terracotta brick 11-1 has a vertically penetrating side rib through hole 11c, and the second side terracotta brick 11-2 has a vertically penetrating U-shaped opening 11-2a, with one side of the U-shaped opening 11-2a facing inward. The first side terracotta brick 11-1 is fitted onto the rib 32 through the side rib through hole 11c, and the second side terracotta brick 11-2 is fastened onto the rib 32 through the U-shaped opening 11-2a. The second side terracotta brick 11-2 is fixedly connected to the curtain wall or the exterior facade of the building by a locking bolt 33. For example, a locking nut is pre-embedded in the curtain wall or the exterior facade of the building. The locking bolt 33 passes through the second side terracotta brick 11-2 and is threadedly connected to the locking nut. At the same time, a countersunk hole can be opened in the second side terracotta brick 11-2 so that the head of the locking bolt 33 is received in the countersunk hole and capped. On the one hand, this improves the aesthetics, and on the other hand, it prevents rainwater erosion.

[0058] In this embodiment, the U-shaped opening 11-2a is equipped with a first anti-detachment structure, which includes a pair of elastic locking blocks 352 (wherein, the inner side of the U-shaped opening 11-2a is provided with a U-shaped protective sleeve 35, and the upper and lower ends of the inner sidewall of the protective sleeve 35 are respectively provided with a pair of elastic locking blocks 352, the protective sleeve 35 is made of metal, and the elastic locking blocks 352 are made of rubber and are vulcanized and bonded to the inner side of the protective sleeve 35).

[0059] In this embodiment, the U-shaped opening 11-2a is equipped with a second anti-detachment structure, which includes a guide sleeve 341, a hinge ear 342, a spring 343, a connecting rod 345, an insert rod 346, and a guide rail 347. The guide sleeve 341 is located in the bolt hole of the second terracotta brick through which the locking bolt 33 passes. The hinge ear 342 and the spring 343 are located in the guide sleeve 341. The two ends of the connecting rod 345 are pivotally connected to the hinge ear 342 and the insert rod 346, respectively. The insert rod 346 is slidably located in the track groove of the guide rail 347 (the bottom wall of the track groove has an avoidance groove 3471 to avoid interfering with the movement of the connecting rod 345). The guide rail 347 is embedded in the second side terracotta brick 11-2, and its track groove opening communicates with the U-shaped opening 11-2a (specifically, the side of the sheath 35 has an opening for inserting the rod 346). 6. The guide sleeve 341 is equipped with an outer limiting nut and an inner limiting nut at both ends. The two ends of the spring 343 abut against the hinge ear 342 and the inner limiting nut respectively (the hinge ear 342 has an annular groove 3421 facing the end of the spring 343, and the end of the spring 343 extends into the annular groove 3421 and abuts against the bottom wall of the annular groove 3421). The screw of the locking bolt 33 passes through the hinge ear 342 and its stepped surface 331 presses the hinge ear 342 onto the spring 343. During the tightening of the locking bolt 33, the stepped surface 331 drives the hinge ear 342 to press down, the spring 343 is compressed, the connecting rod 345 rotates, and drives the insertion rod 346 to extend into the U-shaped opening 11-2a and close the U-shaped opening 11-2a to prevent it from falling out.

[0060] In this embodiment, the first side terracotta brick 11-1 has a pair of vertically penetrating side insertion holes 11c, and the second side terracotta brick 11-2 has a pair of vertically penetrating U-shaped openings 11-2a. The second anti-detachment structure is located on one side of one of the U-shaped openings 11-2a, and its insertion rod 346 can only close the adjacent U-shaped opening 11-2a. In other embodiments, if the locking bolt 33 and the second anti-detachment structure are located between the pair of U-shaped openings 11-2a, and the radial ends of the hinge ear 342 are respectively provided with connecting rods 345, insertion rods 346 and guide rails 347, then both U-shaped openings 11-2a can be closed simultaneously by a single locking bolt 33.

[0061] The guide sleeve 341 has a guide groove 3411 on its side, and the hinge ear seat 342 and the end of the insertion rod 346 are respectively provided with a pair of ears. One end of the connecting rod 345 is pivotally connected to the hinge ear seat 342 through the pair of ears of the guide groove 3411, and the other end is pivotally connected to the pair of ears of the insertion rod 346. The guide groove 3411 and the pair of ears of the hinge ear seat 342 are matched to limit the movement of the hinge ear seat 342.

[0062] Preferably, the outer wall of the guide sleeve 341 is provided with a first anti-detachment nail 3412, and the outer wall of the protective sleeve 35 is provided with a second anti-detachment nail 351. The first anti-detachment nail 3412 and the second anti-detachment nail 351 are both embedded in the second side clay brick 11-2. The pre-embedded setting of the first and second anti-detachment nails 351 can improve the bonding strength between the guide sleeve 341, the protective sleeve 35, and the second side clay brick 11-2.

[0063] In this embodiment, each (horizontal) row of improved terracotta brick unit modules 10 is supported on a separate supporting beam 31;

[0064] The first module 10-1 has a recessed part 11b in the convex-concave structure and the adjacent area of ​​the load-bearing crossbeams on the upper and lower sides (only the side that mates with the second module 10-2 is shown in the figure; in actual design and construction, both sides of the first module 10-1 have convex-concave structures). The second module 10-2 has a raised part 11a in the concave-convex mating structure and the adjacent area of ​​the load-bearing crossbeams on the upper and lower sides. This structure can prevent the subsequent insertion of the reinforcing bar fixing seat into the first side terracotta brick 11-1 of the first module 10-1, which would make the first module 10-1 difficult to disassemble.

[0065] The reinforcing bars 32 of the upper row of improved terracotta brick unit modules 100 are the first reinforcing bars 32-2, and the reinforcing bars 32 of the adjacent lower row of improved terracotta brick unit modules 200 are the second reinforcing bars 32-1 (only two rows of improved terracotta brick unit modules are shown in the figure; the specific number of rows or layers can be increased according to design requirements). The second reinforcing bar 32-1 is a hollow tubular structure. The first reinforcing bar 32-2 can be inserted downwards into the second reinforcing bar 32-1, and the second reinforcing bar 32-1 can be sleeved upwards outside the first reinforcing bar 32-2. The bearing beam 31 has a through hole for the main reinforcing bar 32 to pass through at the position opposite to the second reinforcing bar 32-1. The bearing beam 31 is located at the main reinforcing bar. One side of the 32-hole is provided with a detachable first insert fixing seat, and the other side is provided with a detachable second insert fixing seat. Both the first insert fixing seat and the second insert fixing seat include a sleeve body and a base plate extending outward from one end of the sleeve body adjacent to the bearing beam 31. The base plate is inserted into the slot 311 of the bearing beam 31 (slots 311 are provided on both sides of the through hole of the main insert 32) and locked by bolts. The sleeve body is sleeved on the outside of the first insert 32-2 / second insert 32-1 and has a countersunk hole 3621 extending radially and threaded. The countersunk hole is connected with a bolt (not shown in the figure) for tightening and fixing the first insert 32-2 / second insert 32-1.

[0066] The sleeve body of the first reinforcing bar fixing seat is composed of two semi-circular sleeve halves, namely the outer sleeve half 361 and the inner sleeve half 363. The outer sleeve half 361 and the inner sleeve half 363 have an inwardly extending sealing plate at one end adjacent to the bearing beam 31 (the opening at one end of the sleeve body of the first reinforcing bar fixing seat adjacent to the bearing beam 31 can be blocked or closed by the sealing plate). The outer contour of the inner bottom plate 364 of the inner sleeve half 363 is semi-circular, and the outer sleeve half... The outer contour of the outer bottom plate 362 of 361 is square. After the outer sleeve half 361 is pulled out along the slot 311, the inner sleeve half 363 can be rotated outward and then pulled out, which facilitates the disassembly and separation of the first insert fixing seat, so that the first insert 32-2 can fall down and be received into the second insert 32-1 below, or so that the second insert 32-1 can rise or fall and be sleeved on the outside of the first insert 32-2, so that the corresponding damaged first module 10-1 can be disassembled and replaced.

[0067] In addition, the outer sleeve half 361 has a positioning protrusion on its splicing end face, and the inner sleeve half 363 has a positioning groove 3631 on its splicing end face. The positioning protrusion is inserted into the positioning groove 3631 to improve the stability of the two parts.
