Description

Technical Field

[0001] The present invention relates to the technical field of cement boards, and particularly to an environment-friendly building thermal insulation cement board. Background Art

[0002] Cement boards are common building materials in the construction industry. Their production and manufacturing include two types: prefabrication and casting. The use of cement boards can be used as decorative or load-bearing stress plates according to the requirements of the construction site. At the same time, due to the differences in the installation area and use function, cement boards can be applied to the interior walls, exterior walls or beam slabs of buildings. Therefore, there are significant differences in the models, sizes and specific use functions of cement boards. To meet the application requirements of cement boards, they can be adjusted according to the use specification requirements during manufacturing to meet the application.

[0003] Existing cement boards can adaptively meet the basic requirements according to the application needs during use. However, their efficacy performance is poor in actual use. For example, when applying functions such as heat preservation, water seepage prevention and moisture proof, generally, through the change of materials and filling layers, the use functions and effects are achieved in strips. However, there are problems of limited use in the specific application process: For example, when improving the heat preservation effect of cement boards, by setting a composite filling layer, the dissipation and volatilization of heat energy are reduced, and the heat and cold exchange is reduced to achieve the heat preservation effect. However, the application of this heat preservation method makes the overall air permeability of the cement board poor. When the difference in hot and cold climate changes greatly, local cracks are likely to occur in the whole cement board, resulting in problems such as cracks and water leakage during the use of the cement board. At the same time, under the isolation of the cement board, in a semi-sealed independent space, it is easy to be dry or wet, and the use comfort is poor.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original building cement board. Summary of the Invention

[0005] The purpose of the present invention is to provide an environment-friendly building thermal insulation cement board to solve the problem that while the heat preservation performance of the existing building cement board is satisfied, side effects occur during the use of the cement board, affecting the overall use functions and efficacy.

[0006] To achieve the above purpose, the present invention provides the following technical solution: an environment-friendly building thermal insulation cement board, including: A base cement board, with a shaped groove provided on its top, an internal pipeline is laid in the shaped groove. At the same time, the internal pipelines are fixed by positioning brackets, and a surface layer board is provided above the internal pipelines and the positioning brackets; It further includes: a surface layer board, on which a water permeable component is provided, and a reinforcement grid is embedded in the surface layer board; A sealing connection member is provided at the pipe end connection of the built-in pipe, used for butt joint and filling and sealing treatment between the built-in pipes to maintain the penetration between the built-in pipes; A diversion pipe is fixed to the built-in pipe and the positioning bracket, and the diversion pipe is internally connected to the built-in pipe. A one-way valve body is provided in the middle of the diversion pipe, and a diversion plate is provided between the positioning bracket and the surface layer plate to realize the diversion of liquid towards the one-way valve body.

[0007] Preferably, the permeable member includes a surface layer plate module formed by mixing and pressing silicon-based materials and calcium-based materials as raw materials. Its material is the same as that of aerated concrete blocks, with water permeability. The surface layer plate is divided into small independent modules by a reinforcement grid to improve the stability and strength of the surface layer plate.

[0008] Preferably, the permeable member includes cutting seams opened at equal intervals on the surface layer plate, and the surface layer plate is integrally formed by casting with cement material.

[0009] Preferably, a gathering net is laid on the top of the base cement board, and the gathering net and the base cement board are integrally formed by casting. The gathering net protrudes partially between the grooves on the top of the base cement board, and there is a pore channel reserved between the protruding part of the gathering net and the base cement board.

[0010] Preferably, a connecting barb is fixed at the bottom support foot position of the positioning bracket, and the connecting barb is in through snap-fit positioning with the protruding pore channel part of the gathering net.

[0011] Preferably, the built-in pipe and the positioning bracket are spot-welded and positioned, and the built-in pipe, the positioning bracket, the base cement board and the diversion plate are integrally formed by casting with cement slurry. The diversion plate and the surface layer plate are integrally formed by casting.

[0012] Preferably, the diversion plate is integrally arranged in a wavy structure, and the material of the diversion plate is asbestos fiber. A diversion channel is provided at the through connection part between the diversion plate and the one-way valve body, and the one-way valve body can be set as a Tesla valve.

[0013] Preferably, the sealing connection member includes a convex head and a concave hole at the head and tail ends of the built-in pipe. An annular liquid bag is sleeved in the middle of the outer side of the convex head, and a reinforcement pore channel is reserved at the tail of the convex head; Moreover, barbs are fixed inside the concave hole, and the barbs are evenly distributed at equal angles in the concave hole.

[0014] Preferably, the length of the concave hole is greater than the length of the convex head. The convex head and the concave hole are both arranged in a cylindrical structure, and the convex head and the concave hole are relatively corresponding and penetratively arranged; The positioning connection between the convex head and the annular liquid sac is provided with a concave shape. The annular liquid sac and the convex head are engaged and adhesively positioned. At the same time, the outer diameter of the annular liquid sac is larger than the outer diameter of the convex head, and an adhesive is provided inside the annular liquid sac.

[0015] Preferably, for the splicing and positioning of the base cement board and the built-in pipeline, a sealing connection member is used to position the pipe ends of the built-in pipeline, forming a pipeline system inside the cement board. Through an external pipeline and a valve member, the pipeline system is selectively connected to a floor heating or a ground source heat pump system, improving the heating and heat preservation performance of the cement board.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This environmentally friendly building insulation cement board improves the air permeability and water permeability of the cement board during use, conducts water diversion to prevent water accumulation on the cement board during use, and at the same time can perform heat preservation and heating treatments on the cement board during use. The operation is convenient and it is easy to manufacture. The specific content is as follows: 1. Through the use of the surface layer board, the surface layer board is cast integrally using cement mortar or aerated block material. Equally spaced cutting seams are opened on the surface layer board made of cement slurry material during use, so that both types of surface layer boards have air permeability and water permeability during use. When there is water accumulation on the cement board, the surface layer board can be used for air permeability and water permeability, and under the action of the diversion board and the diversion channel, the infiltrated water is introduced into the diversion pipe, and the infiltrated water is discharged through the built-in pipeline, the external pipeline and the valve. 2. Through the use of the built-in pipeline and the positioning bracket, the two are spot-welded and positioned integrally, and through the filling and casting methods, the base cement board, the built-in pipeline, the positioning bracket, the diversion board and the surface layer board are integrally installed, improving the stability and strength of the cement board during use, preventing delamination during use, and the laying and installation of the built-in pipeline can be cut at the end when the cement board is cut during use. Without affecting the subsequent docking of the built-in pipeline, the normal processing of the cement board can be achieved. According to the requirements of the construction site, the use size of the cement board can be changed, and the sealing connection member is used to position the head and tail ends of the built-in pipelines for docking, achieving the splicing effect between the cement boards. At the same time, the built-in pipeline can be used to discharge the infiltrated water and for heating during use. 3. The concave hole is arranged inside the end of the built-in pipeline, and its length span is reserved large. When cutting the cement board, start cutting from the end of the built-in pipeline. After the cement board is processed, the built-in pipelines in adjacent cement boards can still be docked at the head and tail. Under the action of friction and extrusion during docking, the annular liquid sac is frictionally punctured through the barbs, and under the action of the external force of friction and extrusion, the internal adhesive sealant is discharged, resulting in the adhesion and fixation of the two at the docking interface position of the head and tail ends of the built-in pipeline. The operation is convenient, achieving the connection and positioning effect between the cement boards, and at the same time, the liquid in the built-in pipeline can be diverted and circulated.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1-7 , the present invention provides a technical solution: an environment-friendly building insulation cement board, including: a basic cement board 1, with a shaped groove provided at the top thereof, an built-in pipeline 2 is laid in the shaped groove, and at the same time, the built-in pipelines 2 are fixed by a positioning bracket 3, and a surface layer board 4 is provided above the built-in pipeline 2 and the positioning bracket 3; It further includes: a surface layer board 4, on which a water-permeable component is provided, and a reinforcement grid 10 is embedded in the surface layer board 4; a converging net 5 is laid on the top of the base cement board 1, and the converging net 5 and the base cement board 1 are integrally formed by casting, and the converging net 5 bulges out partially between the grooves on the top of the base cement board 1, and there is a reserved duct between the bulging part of the converging net 5 and the base cement board 1; a connecting barb 501 is fixed at the bottom support leg position of the positioning bracket 3, and the connecting barb 501 is in through snap-fit positioning with the bulging duct part of the converging net 5; the built-in pipe 2 and the positioning bracket 3 are spot-welded and positioned, and the built-in pipe 2, the positioning bracket 3, the base cement board 1 and the diversion plate 8 are integrally formed by casting with cement slurry, and the diversion plate 8 and the surface layer board 4 are integrally formed by casting; When manufacturing the above-mentioned heat-insulating cement board, first, as Figure 4 and Figure 5 shown, the base cement board 1 is cast and formed by using a mold. First, the overall part of the base cement board 1 is prefabricated. When the base cement board 1 is not completely dry during the curing stage, a shaping frame as Figure 4 shown is installed on the top between the grooves on the base cement board 1, and the converging net 5 is fully laid on the base cement board 1 and the shaping frame, and a shallow layer of cement mortar is poured for positioning the converging net 5. Then, the shaping frame is taken out, and the converging net 5 above the shaping frame is set in a convex shape. The converging net 5 improves the adhesion stability between the base cement boards 1 and is also convenient for the subsequent integral casting and forming; Then, as Figure 7 and Figure 8 shown, the built-in pipe 2 and the positioning bracket 3 are welded and positioned with the diversion pipe 6 and the one-way valve body 7. The positioned built-in pipe 2, the positioning bracket 3, the diversion pipe 6 and the one-way valve body 7 are integrally placed on the base cement board 1. During this process, the connecting barb 501 at the bottom of the positioning bracket 3 is snap-fitted with the convex part of the converging net 5, which is convenient for the preliminary positioning of the built-in pipe 2 and the positioning bracket 3 on the base cement board 1; Then, cement material is filled and cast. The above-mentioned whole is integrally formed by casting with the base cement board 1. During the casting process of the cement material, vibration treatment of the base cement board 1 is required to prevent the formation of honeycomb holes inside the cement slurry. Then, the diversion plate 8 is laid on the base cement board 1 where the integrally cast built-in pipe 2, the positioning bracket 3, the diversion pipe 6 and the one-way valve body 7 are placed. Finally, the surface layer board 4 is cast and formed. During this process, the diversion plate 8 is made of asbestos fiber, and its surface layer has a roughened structure, which can be used for adhesion, making the integrally formed surface layer board 4 more stable. At the same time, the surface layer board 4 can also be prefabricated, and then it is connected to the built-in pipe 2, the positioning bracket 3 and the diversion pipe 6 by using cement slurry.

[0021] Embodiment 2: The present invention is also as Figure 1 andFigure 11 and Figure 12 As shown, a sealing connection member for the heat-insulating cement board is also disclosed, which is used for the splicing and assembly of the cement board during use. The specific content is as follows: The sealing connection member is arranged at the pipe end connection of the built-in pipe 2 and is used for the butt joint and filling and sealing treatment between the built-in pipes 2 to maintain the through connection between the built-in pipes 2. The sealing connection member includes a raised head 201 and a concave hole 202 at the head and tail ends of the built-in pipe 2. A ring-shaped liquid sac 203 is sleeved in the middle of the outer side of the raised head 201, and a reinforcing hole 204 is reserved at the tail of the raised head 201. Moreover, barbs 205 are fixed inside the concave hole 202, and the barbs 205 are evenly distributed at equal angles in the concave hole 202. The length of the concave hole 202 is greater than the length of the raised head 201. Both the raised head 201 and the concave hole 202 are arranged in a cylindrical structure, and the raised head 201 and the concave hole 202 are arranged in a corresponding and fitting through manner; A concave shape is provided at the positioning connection between the raised head 201 and the ring-shaped liquid sac 203. The ring-shaped liquid sac 203 is clamped and adhesively positioned with the raised head 201. At the same time, the outer diameter of the ring-shaped liquid sac 203 is greater than the outer diameter of the raised head 201, and an adhesive is provided inside the ring-shaped liquid sac 203; Adopting the above technical solution, when splicing cement boards for use in floor stress-bearing or decorative boards, first, according to the usage requirements, the cement boards can be cut. The cutting position is the position where the end of the built-in pipe 2 is located. When cutting the cement board, the built-in pipe 2 is cut synchronously. Only the concave hole 202 at the end of the built-in pipe 2 will be cut, and the convex head 201 at the head end of the built-in pipe 2 will not be cut. Then, adjacent base cement boards 1 are combined so that the built-in pipes 2 in the base cement boards 1 are butt-jointed end to end. During this process, the convex head 201 will be inserted into the concave hole 202 to assemble the base cement board 1 and the built-in pipe 2. When the convex head 201 is inserted into the concave hole 202, the barbs 205 in the concave hole 202 will give the annular liquid sac 203 on the convex head 201 frictional force and extrusion external force, causing the annular liquid sac 203 to break under the external force. The adhesive stored therein is discharged under the pressure action and introduced between the convex head 201 and the concave hole 202 where the reinforcement hole 204 is located to bond and seal and reinforce the convex head 201 and the concave hole 202, directly achieving the butt-joint effect between the cement boards and between the built-in pipes 2. Then, the pipe systems composed of the built-in pipes 2 inside all the cement boards are connected by using external pipes and valves. For the splicing and positioning of the base cement board 1 and the built-in pipe 2, the pipe ends of the built-in pipe 2 are positioned by using a sealing connection member to form a pipe system inside the cement board. Through the external pipe and valve member, the pipe system is selectively connected to a floor heating or ground source heat pump system to improve the heating and heat preservation of the cement board. The use of the valve can also connect the above pipe system to the sewage pipe, so that the sewage inside the built-in pipe 2 and the collected sewage can be discharged to maintain the cleanliness of the substances inside the built-in pipe 2.

[0022] Embodiment 3: On the basis of Embodiment 1 and Embodiment 2, the present invention discloses the water seepage and sewage discharge effects of the thermal insulation cement board to prevent water accumulation and seepage leakage on the ground. The specific content is as follows: As Figures 1-3 and Figures 8-10 shown, for the base cement board 1, a shaped groove is provided at its top, and a built-in pipe 2 is laid in the shaped groove. At the same time, the built-in pipes 2 are fixed by a positioning bracket 3, and a surface layer board 4 is provided above the built-in pipe 2 and the positioning bracket 3. The diversion pipe 6 is fixed on the built-in pipe 2 and the positioning bracket 3, and the diversion pipe 6 is in communication with the inside of the built-in pipe 2. A one-way valve body 7 is provided in the middle of the diversion pipe 6, and a diversion board 8 is provided between the positioning bracket 3 and the surface layer board 4 to realize the diversion of liquid towards the one-way valve body 7. First, there are two selected forms of the permeable component. The permeable component includes a surface panel 4 module made by mixing and pressing silicon-based materials and calcium-based materials as raw materials. Its material is the same as that of aerated concrete blocks, with water permeability. And the surface panel 4 is divided into small independent modules by a reinforcement grid 10, which improves the stability and strength of the surface panel 4; the permeable component includes cutting seams opened at equal intervals on the surface panel 4, and the surface panel 4 is integrally formed by casting with cement material; The reinforcement grid 10 is used to divide the whole surface panel 4, so that the structure composed of the surface panel 4 and the reinforcement grid 10 has high strength, stability and durability in use. And when in use, the surface panel 4 has a drainage and permeation effect, which can prevent water accumulation on the surface panel 4; At the same time, the guide plate 8 is integrally arranged in a wavy structure, and the material of the guide plate 8 is asbestos fiber. And there is a diversion channel 9 at the through connection between the guide plate 8 and the one-way valve body 7, and the one-way valve body 7 can be set as a Tesla valve; After the surface panel 4 performs permeable drainage, the water is introduced to where the guide plate 8 is located. The guide plate 8 can be used for the adhesion of cement board manufacturing. At the same time, the guide plate 8 itself has water impermeability, so that the water permeated from the surface panel 4 is introduced into the diversion channel 9 through the self-form of the guide plate 8. With the action of the one-way valve body 7, the water flow is introduced and collected into the diversion pipe 6 and then into the built-in pipe 2. Using the pipe system composed of the built-in pipe 2, the permeated water is discharged into the sewage pipe system through the built-in pipe 2 and its connected external pipes and valve bodies; under the action of the built-in pipe 2 and its connected external pipes and valve bodies, through the use of the valve body, the valve body is set indoors in the building. The opening and closing of the valve body makes the built-in pipe 2 and the external pipe connected to the floor heating equipment or the ground source heat pump and other equipment, and heating can be carried out during the laying and installation of the cement board.
