[0003] Existing construction methods often lack specialized and effective handling techniques for splicing insulation boards. This leads to problems such as poor insulation performance, poor structural stability, and uneven appearance at the splicing points, severely affecting the finished product quality of the assembled insulation boards, wasting materials, and increasing project construction costs.

[0004] The purpose of this utility model is to provide an insulation board connection device to solve the technical problem of poor splicing effect of insulation boards in the prior art.

[0008] The connecting piece has two limiting grooves, each of which can be engaged with a fixing component. The expansion structure near the connecting piece expands outward to restrict the axial movement of the connecting piece relative to the fixing component.

[0009] Preferably, the fixing component includes a nail shell and an inner nail, the expansion structure is disposed on the outer periphery of the nail shell, and the inner nail can be driven into the nail shell from the tail end of the nail shell, thereby triggering the expansion structure to expand.

[0010] Preferably, two expansion structures are provided from the tail to the head of the nail shell, namely a first expansion structure and a second expansion structure. The first expansion structure is used to limit the connecting piece, and the second expansion structure is used to increase the radial cross-section of the nail shell.

[0011] Preferably, the first expansion structure is a spring sheet disposed on the outer periphery of the nail shell near the tail end. When the inner nail is driven into the nail shell, the spring sheet can bounce up radially along the nail shell.

[0012] Preferably, there are two spring clips, which are symmetrically arranged about the axis of the nail shell.

[0013] Preferably, the second expansion structure is an expansion bladder disposed at the head of the nail shell, and when the inner nail is driven into the nail shell, the expansion bladder expands outward along the radial direction of the nail shell.

[0019] The insulation board connecting device proposed in this utility model involves first splicing two insulation boards together. A positioning point is preset on each insulation board, and the positions of the two relative positioning points are adjusted according to the length of the connecting piece. After the positioning points are determined, a fixing component is inserted through each positioning point. Then, the two limiting grooves of the connecting piece are respectively engaged with the corresponding fixing components of the two insulation boards, ensuring the connecting piece is tightly against the inner side of the insulation board.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1 to 6 The insulation board connecting device provided in this embodiment of the utility model includes a fixing component 1 and a connecting piece 2. The fixing component 1 can be inserted through the insulation board 100 along the thickness direction. The fixing component 1 has at least one expansion structure arranged along its own axial direction, and the expansion structure can expand outward along the radial direction of the fixing component 1. The connecting piece 2 has two limiting grooves 21, each limiting groove 21 can be engaged with a fixing component 1. The outward expansion of the expansion structure near the connecting piece 2 can restrict the axial movement of the connecting piece 2 relative to the fixing component 1.

[0036] In use, firstly, two insulation boards 100 are spliced ​​together. A positioning point is preset on each insulation board 100. The positions of the two relative positioning points are adjusted according to the length of the connecting piece 2. After the positioning points are determined, a fixing component 1 is inserted through each positioning point. Then, the two limiting grooves 21 of the connecting piece 2 are respectively engaged with the corresponding fixing components 1 of the two insulation boards 100, and the connecting piece 2 is made to be tightly attached to the inner side of the insulation board 100. After the limiting grooves 21 are engaged with the fixing components 1, the expansion structure expands to form a limit on the connecting piece 2. Thus, the two insulation boards 100 can be spliced ​​together through the cooperation of the connecting piece 2, the fixing components 1 and the expansion structure.

[0037] The insulation board connecting device proposed in this utility model has simple operation steps and can quickly and efficiently complete the splicing of insulation boards 100, saving construction time. The expansion structure on the fixing component 1 can effectively restrict the axial movement of the connecting piece 2, thereby ensuring a tight connection between the connecting piece 2 and the fixing component 1, thus enhancing the structural stability of the splice of the two insulation boards 100 and reducing safety hazards caused by weak splicing. In addition, the position of the positioning point can be flexibly adjusted according to the length of the connecting piece 2 to adapt to the splicing requirements of insulation boards 100 of different sizes and specifications, improving the versatility and adaptability of the device.

[0038] It is understood that for two adjacent spliced ​​insulation boards 100, they can be fixed by two fixing components 1 and one connecting piece 2, or multiple fixing components 1 and corresponding connecting pieces 2 can be set for fixing, and the number of them is not limited here.

[0039] The specific structure of the insulation board connection device is described below.

[0040] Regarding the specific structure of the fixing component 1: The fixing component 1 includes a nail shell 11 and an inner nail. An expansion structure is disposed on the outer periphery of the nail shell 11. The inner nail can be driven into the nail shell 11 from its tail, thereby triggering the expansion structure to expand. The nail shell 11 is made of plastic to facilitate expansion and deformation. The expansion effect triggered by the inner nail driving into the nail shell 11 is existing technology in the field, and its working principle will not be elaborated here.

[0041] After the insulation board 100 is fixed, multiple insulation boards 100 need to be spliced ​​together, and concrete needs to be poured inside the insulation board 100. Therefore, to facilitate the fixing of the insulation board 100 to the concrete, two expansion structures are provided from the tail to the head of the nail shell 11, namely a first expansion structure 12 and a second expansion structure 13. The first expansion structure 12 is used to limit the connecting piece 2, and the second expansion structure 13 is used to increase the radial cross-section of the nail shell 11. This increases the contact area and friction between the fixing component 1 and the concrete during concrete pouring, enhances the fixing effect between the insulation board 100 and the concrete, and improves the stability of the overall structure. The synergistic effect of the two expansion structures helps to improve the overall firmness of the insulation board 100.

[0042] It is understood that in other embodiments, depending on the actual needs of the insulation board 100, three or four expansion structures may also be provided on the fixing component 1, and this is not limited here.

[0043] See Figure 4 and Figure 5 Specifically, the first expansion structure 12 is a spring sheet, disposed on the outer periphery of the nail shell 11 near the tail. When the inner nail is driven into the nail shell 11, the spring sheet can spring up radially along the nail shell 11. The spring sheet has good elasticity and sensitivity, can quickly respond to the action of the inner nail being driven in, and can play a timely limiting role, thus improving the reliability of the device. The spring sheet is disposed on the outer periphery of the nail shell 11 near the tail so that when the spring sheet pops out, it abuts against the connecting piece 2, so that the connecting piece 2 is tightly attached to the inner wall of the insulation plate 100.

[0044] Furthermore, two spring clips are provided, symmetrically arranged about the axis of the nail shell 11. This provides a more balanced force when limiting the connecting piece 2, making the axial force on the connecting piece 2 more uniform and thus enhancing the stability of the limiting effect. In addition, the symmetrical arrangement of the two spring clips increases the reliability of the limiting action. Even if one spring clip fails or its performance deteriorates, the other spring clip can still guarantee the limiting function to a certain extent, improving the fault tolerance of the entire device.

[0045] Furthermore, when the spring clip springs up, it extends outward at an angle from the head to the tail of the nail housing 11. Due to the angle of the spring clip, it provides greater resistance when subjected to an outward pull-out force, thereby improving the overall pull-out resistance of the fixing assembly 1 and enhancing the stability of the insulation board 100 connection.

[0046] Specifically, the second expansion structure 13 is an expansion bladder located at the head of the nail shell 11. When the inner nail is driven into the nail shell 11, the expansion bladder expands radially outward along the nail shell 11. After expansion, the expansion bladder increases the contact area and friction with the concrete, thereby enhancing the bonding force between the insulation board 100 and the concrete and improving the overall structural stability. Furthermore, the design of the expansion bladder ensures more uniform expansion, providing consistent support and fixation in all directions and preventing localized instability.

[0047] In other embodiments, the second expansion structure 13 may also be an expansion spring, an expansion plate, etc., which is not limited here, as long as it can increase the radial cross-sectional area of ​​the nail shell 11.

[0048] Since the inner nail needs to be driven into the nail shell 11 from its tail during use, thereby triggering the expansion structure to expand, the fixing component 1 also includes a force-applying member 14 for ease of operation. The force-applying member 14 is located at the tail of the nail shell 11, and its radial cross-section is larger than that of the nail shell 11. This provides a larger and more convenient force-applying surface for construction personnel when installing the fixing component 1, making the operation easier and less strenuous. Simultaneously, the force-applying member 14 acts as a barrier, limiting the nail shell 11 from being driven excessively into the insulation board 100, preventing damage to the insulation board 100 due to excessive driving depth. Furthermore, the larger force-applying member 14 allows for more even force distribution on the fixing component 1 during driving, reducing tilting or displacement of the fixing component 1 caused by uneven force distribution, thereby enhancing the stability of the connection.

[0049] Specifically, the force-applying component 14 includes a fixed frame 141 and a plurality of reinforcing rods 142. The fixed frame 141 is annular, and the plurality of reinforcing rods 142 are spaced apart along the circumference of the fixed frame 141 on its inner circumference. Through the cooperation of the fixed frame 141 and the reinforcing rods 142, the structural strength of the force-applying component 14 is improved. The arrangement of the plurality of reinforcing rods 142 can evenly distribute the force applied to the force-applying component 14 to the entire fixed frame 141, avoiding excessive local stress, thereby protecting the force-applying component 14 and the nail shell 11 attached to it.

[0050] See Figure 6 Two insulation boards 100 are spliced ​​together along their height, and the straight line connecting the positioning points of the two insulation boards 100 extends parallel to the height direction of the insulation boards 100. In this embodiment, the limiting groove 21 forms an opening along the width direction of the connecting piece 2, and a limiting protrusion 211 is formed at the opening of one of the limiting grooves 21 along the length direction of the connecting piece 2. Thus, for the nail shells 11 of the two insulation boards 100, the connecting piece 2 is installed using an upper-hook and lower-clamp method. The limiting groove 21 with the limiting protrusion 211 is longitudinally hooked and clamped to the nail shell 11 of the upper insulation board 100, and the limiting protrusion 211 can effectively prevent the connecting piece 2 from slipping or loosening from the upper nail shell 11; the other limiting groove 21 is laterally clamped to the nail shell 11 of the lower insulation board 100. The upper-hook and lower-clamp installation method is simple and intuitive, and operators can quickly install it, improving installation efficiency.

[0051] Furthermore, a threaded groove 22 is provided in the middle of the connecting piece 2, and the water-stop bolt 3 can be threadedly connected to the threaded groove 22. Through the threaded connection of the water-stop bolt 3 to the threaded groove 22, the fixing strength of the connecting piece 2 is increased, making the splicing structure of the insulation board 100 more stable and reducing deformation and loosening caused by external forces or environmental factors. In harsh environments such as humid and rainy conditions, it can better ensure the reliability and stability of the connection of the insulation board 100.

[0052] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
