Abstract
Description
Technical Field
[0001] This utility model patent relates to the technical field of thermal insulation structures, specifically to rooftop thermal insulation and reinforcement structures. Background Technology
[0002] Thermal insulation structures play a crucial role in the construction industry, especially in roof insulation. With the acceleration of urbanization and people's increasing demands for the comfort of their living environment, roof insulation technology has received widespread attention and application.
[0003] Traditional roof insulation structures typically use insulation materials (such as foam plastics and rock wool) laid on the roof surface to reduce heat transfer and achieve the insulation effect. However, due to the low bonding strength of the internal materials, these traditional insulation structures can cause separation and displacement of the insulation materials, thus affecting the insulation effect.
[0004] In existing technologies, there are usually no effective connection measures between insulation materials within the insulation layer. For example, extruded polystyrene boards are connected by simple splicing, which is prone to displacement and separation when subjected to external forces, thus affecting the overall performance of the insulation layer. Moreover, during long-term use, environmental factors (such as temperature changes and rain erosion) can also easily lead to a decrease in the bonding strength between insulation materials. Utility Model Content
[0005] The purpose of this utility model is to provide a roof insulation and reinforcement structure, which aims to solve the problem of low connection strength of internal materials in the insulation layer in the prior art.
[0006] This utility model is implemented as follows: a rooftop thermal insulation and reinforcement structure includes a thermal insulation layer laid on the rooftop, the interior of which contains an extruded polystyrene board, and a wire mesh layer is laid on the extruded polystyrene board. The extruded polystyrene board and the wire mesh layer are wrapped inside the thermal insulation layer. The wire mesh layer has multiple mesh openings, and there are intersections between adjacent mesh openings. An insertion strip is provided at each intersection, and the insertion strip passes through the extruded polystyrene board.
[0007] Furthermore, the extruded board has an upward-facing top surface, and the wire mesh layer is attached to the top surface.
[0008] Furthermore, the wire mesh has a downward-facing and flat bottom surface, and the bottom surface of the wire mesh layer is attached to the top surface of the extruded polystyrene board.
[0009] Furthermore, the intersection is arranged in a hollowed-out manner to form a hollowed-out area, which is filled with an elastic block. The upper end of the insertion strip is connected to the elastic block, and the lower end of the insertion strip extends downward away from the elastic block.
[0010] Furthermore, the upper end of the insertion strip has a flat end head, which is embedded in the elastic block.
[0011] Furthermore, the end head is enclosed inside the elastic block.
[0012] Furthermore, the hollow area is polygonal in shape, and the wire mesh layer has multiple enclosing strips surrounding the outer periphery of the hollow area. The multiple enclosing strips are connected end to end in sequence to form a closed outer ring. The outer ring surrounds the outer periphery of the hollow area, and the outer periphery of the elastic block is fixedly connected to the outer ring.
[0013] Furthermore, the outer periphery of the elastic block is surrounded by an outer ring, which is embedded inside the elastic block.
[0014] Furthermore, the outer periphery of the insert strip is provided with a plurality of barbs, the barbs are embedded in the extruded board, the plurality of barbs are arranged at intervals along the height direction of the insert strip, the inner ends of the barbs are abutted to the outer periphery of the insert strip, and the outer ends of the barbs are arranged at an angle downward.
[0015] Furthermore, a cement mortar layer is laid on the extruded polystyrene board, and multiple recessed grooves are provided in the extruded polystyrene board. The recessed grooves penetrate the top surface of the extruded polystyrene board to form a top opening, which is exposed in the mesh. The cement mortar layer covers the top surface, passes through the top opening, fills the recessed grooves, and wraps the wire mesh layer inside.
[0016] Compared with existing technologies, the roof insulation reinforcement structure provided by this utility model significantly optimizes the internal structure of the insulation layer by setting extruded polystyrene board and wire mesh layers inside the insulation layer and inserting strips at the intersections of the wire mesh layers. Specifically, it has the following advantages:
[0017] 1) By setting insert strips at the intersection of the wire mesh layers and inserting the insert strips into the extruded polystyrene board, a tight bond between the extruded polystyrene board and the wire mesh layer is achieved, which improves the connection strength between the components inside the insulation layer;
[0018] The insertion of the insert not only enhances the mechanical connection between the extruded board and the wire mesh layer, but also disperses stress through the mesh structure of the wire mesh layer, thus avoiding connection failure caused by local stress concentration.
[0019] 2) The steel wire mesh layer provides additional structural support for the insulation layer, strengthening its overall stability and improving its crack resistance. The insertion strips further bind the extruded polystyrene board and the steel wire mesh layer tightly, enabling the insulation layer to maintain a stable structural shape when subjected to external forces. This effectively prevents the displacement and separation of materials within the insulation layer, which not only improves the insulation layer's resistance to deformation but also enhances its reliability in complex operating environments.
[0020] 3) Extruded polystyrene (XPS) boards have good thermal insulation properties, and the steel wire mesh layer not only strengthens the insulation layer but also gives it good crack resistance. Furthermore, the tight connection between the insert strip and the XPS board enhances the overall thermal insulation effect of the insulation layer. In addition, the mesh structure of the steel wire mesh layer can effectively block the heat transfer path, thus significantly improving the thermal insulation performance of the insulation layer.

[0028] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.
[0029] The roof insulation and reinforcement structure includes an insulation layer 100 laid on the roof, an extruded polystyrene board 101 inside the insulation layer 100, a wire mesh layer 102 laid on the extruded polystyrene board 101, and the extruded polystyrene board 101 and the wire mesh layer 102 are wrapped inside the insulation layer 100; the wire mesh layer 102 has multiple mesh holes, and there are intersections between adjacent mesh holes. An insertion strip 104 is provided at the intersection, and the insertion strip 104 passes through the extruded polystyrene board 101.
[0030] The roof insulation reinforcement structure provided above significantly optimizes the internal structure of the insulation layer 100 by setting an extruded polystyrene board 101 and a wire mesh layer 102 inside the insulation layer 100, and by setting an insert strip 104 at the intersection of the wire mesh layers 102. Specifically, it has the following advantages:
[0031] 1) By setting an insert strip 104 at the intersection of the wire mesh layer 102 and inserting the insert strip 104 through the extruded board 101, the tight connection between the extruded board 101 and the wire mesh layer 102 is achieved, which improves the connection strength between the components inside the insulation layer 100.
[0032] The insertion of the insert strip 104 not only enhances the mechanical connection between the extruded polystyrene board 101 and the wire mesh layer 102, but also disperses stress through the mesh structure of the wire mesh layer 102, thus avoiding connection failure caused by local stress concentration.
[0033] 2) The steel wire mesh layer 102 provides additional structural support for the insulation layer 100, which strengthens the overall stability of the insulation layer 100 and improves its overall crack resistance. The insertion strip 104 further binds the extruded board 101 and the steel wire mesh layer 102 tightly, so that the insulation layer 100 can maintain a stable structural shape when subjected to external forces, effectively preventing the displacement and separation of the internal materials of the insulation layer 100. This not only improves the deformation resistance of the insulation layer 100, but also enhances the reliability of the insulation layer 100 in complex operating environments.
[0034] 3) The extruded polystyrene board 101 itself has good thermal insulation performance, and the steel wire mesh layer 102 not only strengthens the thermal insulation layer 100, but also gives the thermal insulation layer 100 good crack resistance. Furthermore, the tight combination of the insert strip 104 and the extruded polystyrene board 101 enhances the overall thermal insulation effect of the thermal insulation layer 100. In addition, the mesh structure of the steel wire mesh layer 102 can also effectively block the heat transfer path, thus significantly improving the thermal insulation performance of the thermal insulation layer 100.
[0035] In this embodiment, the extruded polystyrene board 101 has an upward-facing top surface, and the wire mesh layer 102 is attached to the top surface; in this way, the wire mesh layer 102 can be in close contact with the extruded polystyrene board 101, providing a basis for subsequent structural connections and helping to enhance the structural stability inside the insulation layer 100.
[0036] In this embodiment, the wire mesh has a flat bottom surface facing downwards, and the bottom surface of the wire mesh layer 102 is attached to the top surface of the extruded polystyrene board 101.
[0037] The flat bottom surface of the wire mesh layer 102 allows it to better fit with the top surface of the extruded polystyrene board 101, increasing the contact area and thus improving the bonding strength between the two, further enhancing the connection strength of the internal materials of the insulation layer 100.
[0038] In this embodiment, the intersection is arranged in a hollowed-out manner to form a hollowed-out area. The hollowed-out area is filled with an elastic block 105. The upper end of the insertion strip 104 is connected to the elastic block 105, and the lower end of the insertion strip 104 extends downward away from the elastic block 105.
[0039] In this way, the insert strip 104 is connected to the intersection of the elastic block 105 and the wire mesh layer 102. The elastic block 105 can provide certain support and buffer for the insert strip 104. At the same time, the extended arrangement of the insert strip 104 can better integrate with the extruded board 101, thereby enhancing the connection stability of the internal structure of the insulation layer 100.
[0040] In this embodiment, the upper end of the insertion strip 104 has a flat end head 106, which is embedded in the elastic block 105. The flat end head 106 increases the contact area between the insertion strip 104 and the elastic block 105, making the connection between the insertion strip 104 and the elastic block 105 more secure.
[0041] In this embodiment, the end head 106 is wrapped inside the elastic block 105; this can better fix the upper end of the insert strip 104, prevent it from loosening or falling off during use, thereby enhancing the connection strength of the internal structure of the heat insulation layer 100.
[0042] In this embodiment, the hollow area is polygonal in shape, and the wire mesh layer 102 has multiple enclosing strips 107 surrounding the outer periphery of the hollow area. The multiple enclosing strips 107 are connected end to end in sequence to form a closed outer ring. The outer ring surrounds the outer periphery of the hollow area, and the outer periphery of the elastic block 105 is fixedly connected to the outer ring.
[0043] This makes the elastic block 105 fixedly connected to the outer ring of the wire mesh layer 102, further enhancing the connection stability between the wire mesh layer 102 and the elastic block 105, improving the integrity of the internal structure of the insulation layer 100, and helping to enhance the connection strength of the internal materials of the insulation layer 100.
[0044] In this embodiment, the outer periphery of the elastic block 105 is wrapped with an outer ring, which is embedded inside the elastic block 105. By wrapping the outer ring with the elastic block 105 and embedding it inside, the connection between the elastic block 105 and the wire mesh layer 102 is strengthened, and the stability of the internal structure of the insulation layer 100 is improved.
[0045] In this embodiment, the outer periphery of the insert strip 104 is provided with a plurality of barbs 108. The barbs 108 are embedded in the extruded board 101. The plurality of barbs 108 are arranged at intervals along the height direction of the insert strip 104. The inner ends of the barbs 108 are connected to the outer periphery of the insert strip 104, and the outer ends of the barbs 108 are arranged at an angle downward.
[0046] By embedding the barbed strip 108 into the extruded polystyrene board 101, the friction and connection strength between the insert strip 104 and the extruded polystyrene board 101 are increased, thereby further enhancing the connection firmness of the internal materials of the insulation layer 100 and realizing a high-strength connection of the internal materials of the insulation layer 100.
[0047] In this embodiment, a cement mortar layer 103 is laid on the extruded polystyrene board 101. The extruded polystyrene board 101 has multiple recessed grooves that penetrate the top surface of the extruded polystyrene board 101 to form a top opening that is exposed in the mesh. The cement mortar layer 103 covers the top surface, passes through the top opening, fills the recessed grooves, and wraps the wire mesh layer 102 inside.
[0048] By laying the cement mortar layer 103 and filling the recessed grooves, the wire mesh layer 102 can be better fixed on the extruded polystyrene board 101. The solidification effect of the cement mortar layer 103 enhances the stability of the internal structure of the insulation layer 100 and improves the overall connection strength of the insulation layer 100.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
