Description

Technical Field

[0001] This utility model relates to the field of building wall technology, and in particular to a building sandwich self-insulating external wall structure. Background Technology

[0002] As my country's wall material innovation and building energy conservation efforts continue to deepen, building energy conservation design standards are becoming increasingly stringent. Building energy conservation and wall insulation technologies have developed rapidly, and new structural systems with the same lifespan as the structure have also emerged and been widely applied in engineering projects. Currently, new buildings typically employ frame structures and frame-shear wall structures, with infill walls accounting for a significant proportion of construction. According to national building energy conservation requirements, self-insulating walls in my country are currently mostly constructed from self-insulating blocks made of composite insulation materials such as concrete composite polystyrene boards. For example, application number 200820172005.2 discloses a sandwich self-insulating external wall structure. Its technical solution is as follows: sandwich self-insulating blocks are placed between beams and columns, and insulation boards are attached to the outside of the beams and columns. Suspension cables are fixed to the outside of the masonry between beams and columns. Its advantages are: this self-insulating external wall structure is convenient to construct, has a short construction period, low cost, good thermal performance, no safety hazards, and can achieve the same lifespan as the building. Its structural design is reasonable and its concept is ingenious and novel.

[0003] The sandwich self-insulating external wall structure disclosed in the above patent still has the following shortcomings in use: 1. The method of preventing falling off by setting up hanging steel cables requires personnel to hang them one by one during subsequent installation, which is inconvenient; 2. After stacking, there will be joints between two adjacent self-insulating blocks. In order to improve the insulation effect, the prior art seals the joints one by one by filling them with sealant. This filling method is cumbersome and labor-intensive. In view of the above, this application proposes a building sandwich self-insulating external wall structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building sandwich self-insulating external wall structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A building sandwich self-insulating exterior wall structure includes a main exterior wall structure, wherein the main exterior wall structure includes two beams and two columns, the two columns being fixed between the two beams, and the two beams and two columns forming a sandwich self-insulating filling space, comprising:

[0007] The sandwich self-insulating mechanism fills the sandwich self-insulating filling space;

[0008] The joint filling mechanism is installed on the upper beam and works in conjunction with the sandwich self-insulating mechanism. The joint filling mechanism is used to fill the joint with sealant.

[0009] There are two insulation boards, which are respectively set on the front and rear sides of the sandwich self-insulating mechanism. The two insulation boards can restrict the front and rear of the sandwich self-insulating mechanism.

[0010] Interior decorative panels are fixed to the rear sides of the two beams and two columns;

[0011] The exterior decorative panels are fixed to the front sides of the two beams and two columns;

[0012] The finishing mortar layer is applied to the front side of the exterior decorative panel;

[0013] A decorative coating is applied to the back of the interior trim panel.

[0014] Preferably, the sandwich self-insulating mechanism includes multiple sandwich self-insulating blocks, which are stacked between two insulation boards. The self-insulating effect is achieved through the cooperation of the multiple sandwich self-insulating blocks and the two insulation boards. Two adjacent sandwich self-insulating blocks are interlocked. The outer side of the sandwich self-insulating blocks is covered with building sealant. Two adjacent building sealants are in close contact. The uppermost and lowermost building sealants are in close contact with the sides of the two beams that are close to each other. The building sealant provides initial sealing at the joint. The sides of the two insulation boards that are close to each other are in close contact with the multiple building sealants. The front side of the multiple sandwich self-insulating blocks located on both sides and in the middle has through holes. Reinforcing steel bars are movably fitted into the through holes. The two insulation boards, the inner decorative board, and the outer decorative board are all fitted onto the multiple reinforcing steel bars. The reinforcing steel bars are used to restrict the corresponding sandwich self-insulating blocks and improve the stability of the installation.

[0015] Preferably, the joint filling mechanism includes a pouring hole on one side of the top of the upper beam, a flow channel on the right inner wall of the pouring hole, multiple discharge holes on the bottom inner wall of the flow channel, all of which are connected to the sandwich self-insulating filling space, a first connecting hole inclined on the left inner wall of the through hole, a second connecting hole on the top inner wall of the through hole, and two third connecting holes on the building sealant, which are respectively connected to the corresponding first and second connecting holes. The third connecting holes are connected to the joints between two adjacent sandwich self-insulating blocks and the joints between the sandwich self-insulating blocks and the column. The arrangement of the third connecting holes, the first connecting holes, and the second connecting holes allows the sealant at the joint to flow into the through hole, thereby achieving a seal between the through hole and the corresponding reinforcing steel bar.

[0016] Preferably, except for the sandwich self-insulating block with reinforcing steel bars, the other sandwich self-insulating blocks are integrally provided with limiting blocks on both sides. The sandwich self-insulating block with reinforcing steel bars has a limiting groove that is locked to the corresponding limiting block. The limiting block and the limiting groove work together to restrict two adjacent sandwich self-insulating blocks.

[0017] Preferably, the inner and outer decorative panels each have multiple slots on the side closest to each other, and the front and rear ends of the reinforcing steel bars are respectively inserted into the corresponding slots.

[0018] Preferably, the front side of the insulation board has multiple movable holes, and the inner wall of the movable holes is in movable contact with the outer side of the corresponding reinforcing steel bars.

[0019] Preferably, the front side of the exterior decorative panel has multiple T-shaped holes, and the front side of the beam and the front side of the column both have multiple bolt holes. The rear side of the interior decorative panel has multiple grooves, and a threaded block is movably fitted in each groove.

The threaded block is threaded onto the corresponding T-bolt. A screwdriver adapter groove is provided on the rear side of the threaded block. By cooperating with the corresponding T-bolt, a fixed connection between the exterior decorative panel, the interior decorative panel, the beam, and the column can be achieved.

[0020] Compared with existing technologies, the beneficial effects of this utility model are:

[0021] 1. The self-insulating sandwich mechanism can achieve the effect of self-insulation. The reinforcing steel bars and limiting blocks in the self-insulating sandwich mechanism can effectively limit and prevent the self-insulating sandwich blocks from falling off during installation.

[0022] 2. By setting up a joint filling mechanism, sealant can be added from the top pouring hole and its own flow can be combined to fill multiple joints with sealant. This filling method is significantly more efficient than the existing method of filling one by one.

[0023] This invention, through a series of structural designs, effectively secures and prevents the sandwich self-insulating blocks from detaching during installation. This securing method only requires direct securing during stacking, significantly improving operational efficiency compared to the existing method of using hanging steel cables. Furthermore, by adding sealant from the top and allowing it to flow naturally, multiple joints are filled with sealant. This filling method, compared to the existing method of filling one by one, significantly improves operational efficiency and reduces labor intensity. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-4 A building sandwich self-insulating exterior wall structure includes a main body of the exterior wall structure, which comprises two beams 1 and two columns 13. The two columns 13 are fixed between the two beams 1, and the two beams 1 and the two columns 13 form a sandwich self-insulating filling space, including:

[0031] The sandwich self-insulating mechanism fills the sandwich self-insulating filling space;

[0032] There are two insulation boards 6, which are respectively set on the front and rear sides of the sandwich self-insulating mechanism. The two insulation boards 6 can restrict the front and rear of the sandwich self-insulating mechanism.

[0033] Interior decorative panel 3 is fixed to the rear side of the two beams 1 and the two columns 13;

[0034] The exterior decorative panel 2 is fixed to the front side of the two beams 1 and the two columns 13;

[0035] Multiple T-shaped holes are provided on the front side of the exterior decorative panel 2. Multiple bolt holes are reserved on the front side of the beam 1 and the front side of the column 13. Multiple grooves are provided on the rear side of the interior decorative panel 3. Threaded blocks 12 are movably fitted in the grooves. The same T-bolt 11 is movably fitted in the T-shaped holes and the corresponding bolt holes. The rear end of the T-bolt 11 extends into the corresponding groove. The inner wall of the front side of the groove has an insertion hole for the corresponding T-bolt 11 to pass through. The threaded block 12 is threaded onto the corresponding T-bolt 11. The rear side of the threaded block 12 has a threaded groove for threaded connection with the corresponding T-bolt 11. The rear side of the threaded block 12 has a screwdriver adapter groove, which can be tightened by an external screwdriver. By cooperating with the threaded block 12 and the corresponding T-bolt 11, the fixed connection between the exterior decorative panel 2, the interior decorative panel 3 and the beam 1 and the column 13 can be realized.

[0036] The finishing mortar layer 5 is set on the front side of the exterior decorative panel 2;

[0037] A decorative coating 4 is applied to the rear side of the inner decorative panel 3;

[0038] The sandwich self-insulating mechanism includes multiple sandwich self-insulating blocks 7, which are stacked between two insulation boards 6. The self-insulating effect is achieved through the cooperation of the multiple sandwich self-insulating blocks 7 and the two insulation boards 6. Two adjacent sandwich self-insulating blocks 7 are interlocked. The outer side of each sandwich self-insulating block 7 is covered with building sealant 8, with adjacent building sealant 8 in close contact. The top and bottom building sealant 8 respectively make close contact with the sides of the two beams 1 that are close to each other. The building sealant 8 provides initial sealing at the joints. The sides of the two insulation boards 6 that are close to each other are also in close contact with the multiple building sealant 8. Multiple sandwich self-insulating blocks 7 located on both sides and in the middle of the 7 have through holes 701 on their front sides. Reinforcing steel bars 9 are movably fitted inside the through holes 701. Two insulation boards 6, inner decorative board 3 and outer decorative board 2 are fitted on the multiple reinforcing steel bars 9. Multiple slots 10 are opened on the side of the inner decorative board 3 and the outer decorative board 2 that are close to each other. The front and rear ends of the reinforcing steel bars 9 are respectively fitted into the corresponding slots 10. Multiple movable holes are opened on the front side of the insulation board 6. The inner wall of the movable hole is in movable contact with the outer side of the corresponding reinforcing steel bar 9. The movable hole is used for the corresponding reinforcing steel bar 9 to pass through. The reinforcing steel bar 9 is used to restrict the corresponding sandwich self-insulating blocks 7 and improve the installation stability.

[0039] Except for the sandwich self-insulating block 7 with reinforcing steel bars 9 installed, the other sandwich self-insulating blocks 7 are integrally provided with limiting blocks 16 on both sides. The sandwich self-insulating block 7 with reinforcing steel bars 9 has a reserved limiting groove that is engaged with the corresponding limiting block 16. The limiting block 16 and the limiting groove cooperate to restrict the two adjacent sandwich self-insulating blocks 7 on the left and right.

[0040] A joint filling mechanism is installed on the upper beam 1;

[0041] The joint filling mechanism includes a pouring hole 101 on one side of the top of the upper beam 1. A flow channel 14 is provided on the inner right side of the pouring hole 101. Multiple discharge holes 15 are provided on the inner bottom of the flow channel 14. All discharge holes 15 are connected to the sandwich self-insulating filling space. A first connecting hole 703 is provided on the inner left side of the through hole 701. A second connecting hole 702 is provided on the inner top of the through hole 701. Two third connecting holes are provided on the building sealant 8. The two third connecting holes are connected to the corresponding first connecting hole 703 and second connecting hole 702 respectively. The third connecting holes are connected to the joints between two adjacent sandwich self-insulating blocks 7 and the joints between the sandwich self-insulating blocks 7 and the column 13. The setting of the third connecting holes, the first connecting holes 703 and the second connecting holes 702 allows the sealant at the joint to flow into the through hole 701, thereby achieving the sealing between the through hole 701 and the corresponding reinforcing steel bar 9.

[0042] This utility model, through a series of structural designs, can effectively lock and prevent the sandwich self-insulating blocks 7 from falling off during installation. This locking and fixing method only requires direct locking during stacking, which significantly improves operational efficiency compared to the existing method of locking with hanging steel cables. Furthermore, by adding sealant from the top and allowing it to flow, multiple joints can be filled with sealant. This filling method significantly improves operational efficiency and reduces labor intensity compared to the existing method of filling one by one.

[0043] Working principle: During installation, the outer decorative panel 2 is first connected to the beam 1 and column 13 using multiple T-bolts 11. Next, the front insulation board 6 is installed into the self-insulating sandwich filling space. Then, multiple self-insulating sandwich blocks 7 are stacked within the self-insulating sandwich filling space and mutually restrained by corresponding limiting blocks 16. Next, the rear insulation board 6 is installed within the self-insulating sandwich filling space. Then, multiple reinforcing steel bars 9 are sequentially inserted into the corresponding movable holes, through holes 701, and slots 10. After insertion, the inner decorative panel 3 is fitted onto the reinforcing steel bars 9 and screwed onto the corresponding T-bolts 11 using threaded blocks 12. This achieves a fixed connection between the outer decorative panel 2 and the inner decorative panel 3 and the beam 1 and column 13. The multiple reinforcing steel bars 9, along with the fixed outer decorative panel 2 and inner decorative panel 3, ensure a secure connection. The interior decorative panel 3 is clipped in, and the reinforcing steel bar 9 is fitted into the through hole 701 opened on the sandwich self-insulating block 7, thereby vertically restricting the sandwich self-insulating block 7. At the same time, with the cooperation of multiple restricting blocks 16, the restriction between two adjacent sandwich self-insulating blocks 7 can be realized. This can effectively restrict and fix multiple sandwich self-insulating blocks 7 stacked together, thereby effectively reducing the risk of multiple sandwich self-insulating blocks 7 falling off. This restriction and fixation method only requires direct clipping during stacking. Compared with the existing technology of restricting by hanging steel cables, its operation efficiency is significantly improved. The clipping of the restricting block 16 utilizes the elasticity of multiple building sealing rubber sheets 8, which form a space for the restricting block 16 to enter when the pushing force is applied, and clipping when the pushing force is stopped or when manually moved back.

[0044] After the construction is completed, the joints can be initially sealed by the construction sealant 8. When filling the joints with sealant, sealant can be added into the pouring hole 101. Since the sealant is a fluid, it flows into the flow channel 14. The sealant in the flow channel 14 flows out through multiple discharge holes 15 to the joint above. Under the action of gravity, the sealant gradually flows downward, so that multiple joints are filled with sealant. At the same time, some of the sealant in the joint enters the gap between the through hole 701 and the reinforcing steel bar 9 through the corresponding third connecting hole, second connecting hole 702 and first connecting hole 703, thereby sealing the through hole 701 and the reinforcing steel bar 9. By adding sealant from the top and its own flow, multiple joints can be filled with sealant. Compared with the existing technology of filling one by one, this filling method significantly improves the operation efficiency and reduces the labor intensity.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
