Description

Technical Field

[0001] The utility model relates to the technical field of color steel plates, in particular to a color steel plate core plate with high efficiency and heat insulation. Background Art

[0002] Color-coated steel plate, also known as color coated steel plate, is a product made of cold-rolled steel plate, electrogalvanized steel plate, hot-dip galvanized steel plate or aluminum-zinc-coated steel plate as the substrate. After surface degreasing, phosphating and chromate treatment, it is coated with organic coating and baked. Color-coated steel plate has both the strength of steel plate and good corrosion resistance. The organic coating on its surface can be formulated into various colors, and can be made into various patterns such as wood grain, cloth grain and leather grain with the help of printing and embossing technology, giving the steel plate a beautiful appearance.

[0003] Color steel plates are generally used as building materials for factories or mobile houses on construction sites. While meeting the requirements of mechanical strength, there is also a demand for heat insulation. Generally, foam plastics, rock wool, glass wool, asbestos wool and other insulation materials are used as the core board of the color steel plate, and then steel plates are applied on the surface to form color steel plates with heat insulation effects. However, when asbestos wool is used as a heat insulation material and the color steel plates are placed vertically and used as walls, the asbestos wool and the steel plates are generally connected by glue. After being subjected to high temperature conditions in summer, the glue or individual materials are also easily brittle and powdery, resulting in a decrease in the bonding strength between the asbestos wool and the steel plate. When the color steel plate is in use, the asbestos wool will also fall due to its own gravity, resulting in a large amount of insulation material piled up below the color steel plate, affecting the heat insulation effect of the rest of the color steel plate.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a color-coated steel core plate with high efficiency and heat insulation.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a highly efficient heat-insulating color steel core plate, comprising a thermal insulation layer and a bottom layer connected to each other, a steel plate layer is arranged at one end of the thermal insulation layer away from the bottom layer, the thermal insulation layer and the bottom layer are both an integral structure, wherein the thermal insulation layer is a flexible and elastic foam plastic, the bottom layer is an asbestos material, a plurality of through holes are penetrated through the bottom layer, a fixing component penetrating the thermal insulation layer is arranged on the through holes, a plurality of protrusions are fixedly connected to the surface of the thermal insulation layer away from the bottom layer, the fixing component extends from a position between the plurality of protrusions and fixes the steel plate layer, the thermal insulation layer and the bottom layer.

[0007] By adopting the above technical scheme and utilizing the thermal insulation layer and bottom layer of the integrated structure, the color steel plate can still utilize its own stability when placed vertically to prevent the thermal insulation layer and the bottom layer from falling downward, thereby increasing the thermal insulation effect of the color steel plate, and then utilizing the fixed components to control the distance between the steel plate layer and the bottom layer, thereby increasing the pressure of the steel plate layer and the bottom layer on the thermal insulation layer at the position of the fixed components, thereby forming a number of support points on the distribution surface of the thermal insulation layer that block the movement of the thermal insulation layer.

[0008] The utility model is further configured as follows: the fixing assembly includes a connecting sleeve and a plurality of connecting rods, the plurality of connecting rods are fixedly connected to the inner wall of the through hole away from the thermal insulation layer and are arranged in a circular array, and the connecting rods extend toward the thermal insulation layer, the connecting sleeve is arranged on the surface of the steel plate layer and extends into the through hole, and the center of the circular array of the plurality of connecting rods is located on the axis of the connecting sleeve, and an abutment ring is fixedly connected to the outer side of one end of the connecting sleeve close to the thermal insulation layer, and a plurality of protrusions are fixedly connected to one end of the connecting rods close to the center of their circular array, and the abutment ring is snapped into a position between two adjacent protrusions in height.

[0009] By adopting the above technical scheme, the connecting sleeve is first passed through the thermal insulation layer from the surface of the steel plate layer and penetrated into the through hole, and then the connection structure between the bottom layer and one end of the connecting rod and the elastic characteristics of the connecting rod itself are utilized. When the connecting sleeve is pressed and the connecting sleeve and the abutment ring are penetrated into the through hole, the abutment ring abuts against the inclined surface of the protrusion on the connecting rod and pushes the connecting rod to bend in the horizontal direction, and the abutment ring is stuck between two adjacent protrusions. The connecting rod is then reset by its own elastic force, and the connecting sleeve drives the steel plate layer to move when moving downward. The steel plate layer squeezes the protrusion and the thermal insulation layer. When the connecting sleeve is released, the protrusion and the thermal insulation layer recover and apply an upward force to the steel plate layer and the connecting sleeve, so that the abutment ring abuts against the protrusion, completing the connection between the steel plate layer, the bottom layer and the thermal insulation layer. At the same time, the thermal insulation layer is squeezed at the connection point, thereby increasing the support point of the thermal insulation layer when placed vertically.

[0010] The utility model is further configured as follows: the extension direction of the protrusion on the thermal insulation layer is the same as the extension direction of the protrusion formed by the bending of the steel plate layer, the steel plate layer fits the surface of the thermal insulation layer, and the protrusion height is greater than the thickness of the steel plate layer and is elastic.

[0011] By adopting the above technical scheme, when the steel plate layer and the thermal insulation layer are assembled, the protrusions on the thermal insulation layer are used to form positioning points and fit into the recessed points on the steel plate layer, thereby reducing the difficulty of assembling the two. At the same time, when the steel plate layer, the thermal insulation layer and the bottom layer are connected by the fixed components, the protrusions are squeezed, further increasing the reaction force and the force of lifting the steel plate layer, thereby increasing the connection effect. At the same time, the protrusions can also seal the space between the steel plate layer and the thermal insulation layer, reduce the large space between the steel plate layer and the thermal insulation layer, and use the steel plate layer of thermal insulating plastic material to increase its thermal insulation effect.

[0012] The utility model is further configured that a cavity is formed between the protrusion, the steel plate layer and the thermal insulation layer.

[0013] By adopting the above technical scheme, using a structural setting in which the angle between the protruding side surface and the horizontal plane is smaller than the angle between the protruding side surface of the steel plate layer and the horizontal plane, when the steel plate layer is connected to the thermal insulation layer and the protrusion is squeezed, not only the protrusion is used to fill the depression on the steel plate layer, but also two cavities are formed at its side wall position.

[0014] The utility model is further configured as follows: the cross-sectional shapes of the protrusion and the abutment ring are right-angled triangles with rounded corners, and the right-angled sides of the two are respectively on the vertical plane and the horizontal plane, the acute angle of the triangle in the cross-sectional shape of the abutment ring is located below its horizontal right-angled side, and the acute angle of the triangle in the cross-sectional shape of the protrusion is located above its horizontal right-angled side.

[0015] By adopting the above technical solution and utilizing the configuration of the cross-sectional shapes of the protrusions and the abutment ring, when the abutment ring is inserted between the protrusions, it can prevent the abutment ring from being withdrawn, thereby increasing its connection strength.

[0016] The utility model is further configured as follows: the inner wall of the connecting sleeve is provided with a thread, and the maximum diameter of the thread is smaller than the minimum diameter of the plurality of circular array tracks.

[0017] By adopting the above technical solution and utilizing the threads on the inner wall of the connecting sleeve, when fixing the steel plate layer, the thermal insulation layer and the bottom layer to the ground or other objects, the space on the inner wall of the connecting sleeve can be filled with bolts, while at the same time the steel plate layer can be connected to the ground and the extrusion force of the steel plate layer toward the thermal insulation layer can be further increased, that is, the extrusion force of the steel plate layer and the bottom layer toward the thermal insulation layer can be increased, thereby further increasing the supporting effect of the thermal insulation layer on the plane on which it is located.

[0018] In summary, the utility model has the following beneficial effects:

[0019] On the one hand, the integrated structure of the thermal insulation layer and the bottom layer is utilized to prevent the thermal insulation layer and the bottom layer from being affected by their own gravity and stacking at a lower position when the color steel plate is placed vertically, thereby increasing the overall thermal insulation efficiency of the color steel plate. The fixed components are then used to reduce the distance between the steel plate layer and the bottom layer, thereby squeezing the thermal insulation layer at the position of the fixed components. Even if the thermal insulation layer and the bottom layer are in a loose state, several fixed components can be used to form support points at various positions of the thermal insulation layer and the bottom layer, thereby preventing the thermal insulation layer and the bottom layer from falling, thereby increasing the thermal insulation efficiency of the color steel plate.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Example:

[0030] This is a highly efficient heat-insulating color steel core board, such as Figures 1 to 6As shown, it includes a thermal insulation layer 11 and a bottom layer 12 connected to each other, a steel plate layer 17 is arranged at one end of the thermal insulation layer 11 away from the bottom layer 12, the thermal insulation layer 11 and the bottom layer 12 are both integral structures, wherein the thermal insulation layer 11 is a flexible and elastic foam plastic, the bottom layer 12 is an asbestos material, a plurality of through holes 15 are penetrated on the bottom layer 12, a fixing component penetrating the thermal insulation layer 11 is arranged on the through holes 15, a plurality of protrusions are fixedly connected to the surface of the thermal insulation layer 11 away from the bottom layer 12, the fixing component extends from a position between the plurality of protrusions and fixes the steel plate layer 17, the thermal insulation layer 11 and the bottom layer 12, the fixing component includes a connecting sleeve 13 and a plurality of connecting rods 14, the plurality of connecting rods 14 are fixedly connected to the inner wall of the through hole 15 away from the thermal insulation layer 11 and are arranged in a circumferential array, and the connecting rods 14 extend toward the thermal insulation layer 11, the connecting sleeve 13 is arranged on the surface of the steel plate layer 17 and extends into the through hole 15, and the center of the circumferential array of the plurality of connecting rods 14 is located at the connecting sleeve 13 The connecting sleeve 13 is on the axis of the thermal insulation layer 11, and the outer side of the connecting sleeve 13 near the end of the thermal insulation layer 11 is fixedly connected with a contact ring 16. Several connecting rods 14 are fixedly connected with several protrusions at one end near the center of the circumferential array, and the contact ring 16 is stuck in the position between two adjacent protrusions in height. The extension direction of the protrusion on the thermal insulation layer 11 is the same as the extension direction of the protrusion formed by the bending of the steel plate layer 17. The steel plate layer 17 fits the surface of the thermal insulation layer 11, and the protrusion height is greater than the thickness of the steel plate layer 17 and has elasticity. A cavity is formed between the protrusion, the steel plate layer 17 and the thermal insulation layer 11. The cross-sectional shape of the protrusion and the contact ring 16 presents a right triangle with chamfered corners, and the right-angled sides of the two are respectively on the vertical plane and the horizontal plane. The acute angle of the triangle in the cross-section of the contact ring 16 is located below its horizontal right-angled side, and the acute angle of the triangle in the cross-section of the protrusion is located above its horizontal right-angled side. The inner wall of the connecting sleeve 13 is provided with a thread, and the maximum diameter of the thread is less than the minimum diameter of the trajectories of the several circular arrays.

[0031] When installing the color steel plate on the roof, first lay the thermal insulation layer 11 and the bottom layer 12 connected as one on the roof, then cover the steel plate layer 17 on the top surface of the thermal insulation layer 11, and use the protrusions on the thermal insulation layer 11 to connect with the depressions on the steel plate layer 17 to complete the positioning of the steel plate layer 17 and then pass the connecting sleeve 13 through the holes on the steel plate layer 17 and clamp the connecting rods 14 in the through holes 15. When pressing the connecting sleeve 13, the steel plate layer 17 is used to apply pressure to the thermal insulation layer 11, so that the thermal insulation layer 11 undergoes elastic deformation, and at the same time, the connecting sleeve 13 penetrates into the holes on the steel plate layer 17 and clamps the connecting rods 14 in the through holes 15. When the connecting rod 14 is between the two protrusions, the abutting ring 16 on the connecting sleeve 13 first pushes the protrusion on the connecting rod 14 outward and causes the connecting rod 14 to undergo elastic deformation.

At the same time, the thermal insulation layer 11 and the bottom layer 12 are integrated to further increase the distribution effect of the thermal insulation layer 11 on the surface of the color steel plate, thereby further increasing the thermal insulation effect of the color steel plate. At the same time, when the steel plate layer 17 squeezes the thermal insulation layer 11, the thickness of the thermal insulation layer 11 is greater than the thickness of the depression on the steel plate layer 17, so that the bulge on the thermal insulation layer 11 is also squeezed, that is, the bulge abuts against the steel plate layer 17, thereby connecting the depression on the steel plate layer 17 with the thermal insulation layer 11. The cavity between the two sides is filled, wherein the angle between the protruding side and the horizontal plane is smaller than the angle between the protruding side of the steel plate layer and the horizontal plane, thereby forming a cavity, that is, increasing the thermal insulation effect of the color steel plate, and also using the protrusion to support the steel plate layer 17, further increasing the mechanical properties of the color steel plate, and then using the connecting rod 14 to be arranged at the side wall of the through hole 15, and the threaded structure of the inner wall of the connecting sleeve 13, so that when the connecting sleeve 13 connects the steel plate layer 17, the thermal insulation layer 11 and the bottom layer 12, the bolts can be engaged with the threads at the connecting sleeve 13 and pass through the through hole 15, so that the color steel plate can be connected to the outside world by bolts;

[0032] When the color steel plate needs to be installed vertically, first lay the thermal insulation layer 11 and the bottom layer 12 flat on the ground, then place the steel plate layer 17 on the thermal insulation layer 11 and connect the steel plate layer 17 with the thermal insulation layer 11 and the bottom layer 12, then place the connector of the steel plate layer 17, the thermal insulation layer 11 and the bottom layer 12 numerically and connect it to an external object through bolts.
