Description

Technical Field

[0001] This utility model belongs to the technical field of construction insulation boards, and particularly relates to a connector for an internal insulation board. Background Technology

[0002] Built-in insulation board is a new type of material used for building insulation. The most common type is the steel mesh built-in insulation board. The inner side of the steel mesh built-in insulation board is an insulation layer, and the outer side is a galvanized steel mesh. Metal wires pass through the built-in insulation core material and are connected to the steel wire mesh as one unit.

[0003] This structure offers excellent thermal insulation: the insulation material is placed in the middle of the wall, effectively blocking heat transfer, and the concrete protective layer ensures more stable insulation performance. It also boasts high safety performance: using non-combustible or flame-retardant insulation materials, coupled with the concrete protective layer, effectively prevents fires and improves building fire safety. Furthermore, it has a long service life: poured simultaneously with the building's structural layers, the insulation layer has the same lifespan as the building, solving problems such as easy detachment and cracking of traditional insulation layers, reducing later maintenance and replacement costs. Finally, it is easy to install: installation only requires binding and fixing, eliminating the need for complex pasting and anchoring processes like traditional insulation, effectively shortening the construction period.

[0004] Currently, built-in insulation panels are suitable for various building structures, such as residential, commercial, and industrial buildings. In cold regions, they effectively reduce indoor heat loss and lower heating energy consumption; in hot regions, they reduce outdoor heat transfer indoors, lowering air conditioning energy consumption. Built-in insulation panels have broad application prospects, especially for buildings with high insulation and fire protection requirements, such as public buildings like schools, hospitals, and hotels, as well as high-end residences with high aesthetic requirements.

[0005] The connectors for the built-in insulation panels play a crucial role in the construction effect. During the pouring process, displacement of the insulation panels and reinforcing mesh can easily occur, affecting the final insulation performance. To address this issue, snap-fit ​​connectors are commonly used. These connectors include a first limiting plate, a second limiting plate, a connecting part, and an axial limiting structure. The first limiting plate is located on one side of the insulation panel, and the second limiting plate has a threaded hole that mates with the guide part. The connecting part is fixed to the side of the first limiting plate away from the second limiting plate and includes a receiving groove, a first clearance groove, and a second clearance groove. The axial limiting structure is connected to the bottom of the receiving groove and includes an elastic part. The elastic part forms a limiting space with the bottom wall of the receiving groove, which can axially limit the anti-crack mesh and improve the connection strength.

[0006] For example, patent document CN217924177U discloses a fixing structure for built-in insulation boards and a cast-in-place concrete wall with built-in insulation boards, relating to the field of built-in insulation structure technology, to solve the problem of cumbersome and inconvenient operation of the connectors used to fix the wall, insulation board and steel mesh in the prior art. This fixing structure is used to connect the wire mesh layer, the insulation board layer and the main steel reinforcement layer into a whole, including connectors, fixing parts, positioning parts, wire mesh limiting parts and main steel reinforcement connecting parts. The fixing part is fixedly connected to the connector, and the wire mesh limiting part and the positioning part can be detachably connected to the connector. The wire mesh limiting part and the positioning part are respectively located on both sides of the fixing part. The wire mesh layer and the connector can be connected through the wire mesh limiting part. The fixing part and the positioning part are respectively located on both sides of the insulation board layer. The end of the connector away from the wire mesh limiting part is provided with a main steel reinforcement connecting part, and the main steel reinforcement layer can be connected to the connector through the main steel reinforcement connecting part.

[0007] It can fix the steel mesh and insulation board, preventing displacement during the pouring process. However, if the insulation board is not placed at the positioning point in one go, it is difficult to move, which will also cause the steel mesh to shift. The steel mesh needs to be moved again later, making it very inconvenient to use. Utility Model Content

[0010] The insertion rod has a thread in the middle, and a nut is screwed onto the thread. The movable plate is connected to the two nuts and is set opposite to each other.

[0011] The steel mesh fixing part includes a stop plate connected to the insert rod, a sleeve on the insert rod, a gap between the sleeve and the stop plate for the steel mesh, and the sleeve and the insert rod are connected by a tightening bolt.

[0020] 1-Reinforcing mesh; 2-Insulation rod; 3-Insulation board; 4-Moving plate; 5-Nut; 6-Binding steel bar; 7-Abutting plate; 8-First connecting plate; 9-Second connecting plate; 10-Sleeve; 11-Insulation gap; 12-Stop rod; 13-Reinforcing mesh gap; 14-Long hole; 15-Bolt. Detailed Implementation

[0021] Example 1, built-in insulation board connector, such as Figure 1 and Figure 2 As shown, the built-in insulation board 3 connector described in this application is used to connect the insulation board 3 with the steel mesh 1 and the main steel bars. In particular, the connection between the insulation board 3 and the steel mesh 1 has high stability and good flexibility, which can effectively reduce the phenomenon of displacement of the two during the pouring process and greatly improve the use effect.

[0022] The built-in insulation board connector includes a rod 2. During implementation, the rod 2 can be made of reinforcing steel, making the material readily available and ensuring its stability within the concrete structure. In this embodiment, one end of the rod 2 is provided with a steel mesh 1 fixing part, which secures the rod 2 to the steel mesh 1. The other end of the rod 2 is the main reinforcing steel connection end, through which the rod 2 is connected to the main reinforcing steel.

[0023] In addition, the insertion rod 2 is provided with two movable plates 4, with a pre-reserved insulation gap 11 between the two movable plates 4. The two movable plates 4 can move along the length of the insertion rod 2. To limit this structure, this embodiment also discloses a structural form of the movable plates 4: a thread is provided in the middle of the insertion rod 2, and two nuts 5 are screwed onto the thread. The two nuts 5 are respectively connected to the two movable plates 4 in a fixed connection manner, and the two nuts 5 are respectively connected to the outer side of the two movable plates 4. In this way, when it is necessary to move the movable plates 4, it is only necessary to rotate the insertion rod 2, and at the same time, the movable plates 4 are locked, so that the movable plates 4 cannot rotate with the insertion rod 2. Thus, the movable plates 4 can only move horizontally on the insertion rod 2 relative to the insertion rod 2. As for how to lock the movable plates 4, there are many ways to achieve this. The simplest way is to hold them by hand, so that the movable plates 4 cannot rotate on the insertion rod 2 and can only move horizontally on the insertion rod 2. In this embodiment, the thread is not shown in the figure. Providing threads on the rod body is a mature existing technology.

[0024] Meanwhile, to secure the insulation board 3 to the reinforcing mesh 1, a first connecting plate 8 is provided on the movable plate 4 near the fixing part of the reinforcing mesh 1, and a second connecting plate 9 is provided on the fixing part of the reinforcing mesh 1. The first connecting plate 8 and the second connecting plate 9 are positioned one outside and one inside, respectively, and are in close contact. Both the first connecting plate 8 and the second connecting plate 9 have horizontally arranged elongated holes 14, through which bolts 15 connecting the first connecting plate 8 and the second connecting plate 9 are inserted. During operation, when the insert rod 2 is rotated, the movable plate 4 moves the insulation board 3 on the insert rod 2. Simultaneously, the movable plate 4 causes the first connecting plate 8 to slide horizontally relative to the second connecting plate 9. Once it reaches the positioning point, it stops moving. At this point, the first connecting plate 8 and the second connecting plate 9 are connected by the bolts 15, which are connected within the elongated holes 14. The elongated holes 14 provide the first connecting plate 8 and the second connecting plate 9 with the necessary displacement, making the adjustment process more flexible.

[0025] The structure of the fixing part of the reinforcing mesh 1 is described in detail below: The fixing part of the reinforcing mesh 1 includes a stop plate connected to the insert rod 2. The stop plate includes at least two stop rods 12, which are evenly distributed around the insert rod 2. In this embodiment, there are two stop rods 12. The insert rod 2 is provided with a sleeve 10. A gap 13 for the reinforcing mesh is reserved between the sleeve 10 and the stop plate. In use, the reinforcing mesh 1 is clamped in the gap 13, and the sleeve 10 is connected to the insert rod 2 by a tightening bolt 15. When using it, first insert the insert rod 2 into the steel mesh 1. At the same time, on the other side of the steel mesh 1, where the stop plate is located, place the steel mesh 1 against the stop plate. Move the sleeve 10 so that the sleeve 10 also adheres to the steel mesh 1. Then, use the tightening bolt 15 to fix the sleeve 10 and the insert rod 2 together. In this way, the steel mesh 1 is fixed. This fixing method has a large contact area and is relatively convenient to use, as it only requires tightening the tightening bolt 15.

[0026] To secure the insert rod 2 to the main reinforcing steel, a binding steel bar 6 is provided at the connection end of the insert rod 2 near the main reinforcing steel. The insert rod 2 is then tied to the main reinforcing steel using the binding steel bar 6. This fixing method is simple, quick, and effective. Simultaneously, a support plate 7 is provided at the connection end of the main reinforcing steel, and the support plate 7 is screwed onto the formwork. During use, the support plate 7 can also serve as a force-bearing point, allowing the insert rod 2 to rotate.

[0027] During operation, the insert rod 2 is first inserted into the reinforcing mesh 1. Simultaneously, the sleeve 10 is moved so that the sleeve 10 and the stop plate clamp the reinforcing mesh 1, improving stability. Next, the movable plate 4 near the sleeve 10 is moved onto the insert rod 2 as the nut 5 rotates, allowing the insert rod 2 to pass through the insulation board 3. Then, another movable plate 4 is moved onto the insert rod 2 along with the nut 5, placing it against the insulation board 3. At this point, the two movable plates 4 are located on either side of the insulation board 3, clamping it between them. Then, the insert rod 2 is rotated. Under the action of the thread and the nut 5, the two movable plates 4 move the insulation board 3 along the insert rod 2. Once it reaches the set position, the first connecting plate 8 and the second connecting plate 9 are fixed together using bolts 15. This achieves the fixation of the reinforcing mesh 1 and the insulation board 3. Finally, the insert rod 2 is tied to the main reinforcing steel using the binding steel 6, ensuring a secure tie. During the pouring process, concrete will be poured between the steel mesh 1 and the insulation board 3, and between the insulation board 3 and the formwork. Using the connectors described in this embodiment, the steel mesh 1 and the insulation board 3 can be stably connected. During the pouring process, the insulation board 3 will not float or the steel mesh 1 will not shift.

[0028] The built-in insulation board 3 connector described in this utility model can connect the insulation board 3 and the steel mesh 1. The connection is highly stable, which greatly improves the quality of the final product. At the same time, the connection process is fast. In addition, fine positioning can be performed after the insulation board 3 is connected to the insert rod 2, which reduces the construction difficulty and makes it more flexible to use.

[0029] Example 2 differs from Example 1 in that two cuboid-shaped locking blocks 16 are provided on the insulation board 3. Both locking blocks 16 are fixed to the insulation board 3 and respectively attached to both sides of the movable plate 4. By setting the locking blocks 16, the rotation of the movable plate 4 can be restricted. When the insertion rod 2 rotates, the movable plate 4 can only move horizontally relative to the insertion rod 2. This is because the bottom of the insulation board 3 is usually connected to the foundation and is not suspended. Thus, the insulation board 3 itself does not have the condition to rotate in the vertical direction. Subsequently, the movable plate 4 is attached to the locking blocks 16, and the locking blocks 16 restrict the rotation of the movable plate 4. Since the insulation board 3 cannot rotate, the movable plate 4 cannot rotate relative to the insertion rod 2 either, and can only move horizontally on the insertion rod 2. It should be noted that in this example, the locking blocks 16 can be fixed after the movable plate 4 clamps the insulation board 3, and the fixing method can be adhesive.
