[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention realizes a tight seal between the heating pipe and the thermal insulation brickwork by arranging a pipe installation groove on the thermal insulation brickwork body and equipping it with a pipe fixing mechanism and a foaming reaction mechanism, thereby ensuring excellent thermal insulation performance and reducing heat loss. The design of the first high-pressure spray can and the second high-pressure spray can utilizes the downward pressure of the pipe holder when fixing the pipe to trigger the foaming reaction, thereby realizing fast and accurate on-site foaming filling, which not only simplifies the construction process, but also ensures the uniformity and density of the foam filling and improves the thermal insulation effect. Through the design of the flow channel, reaction groove, baffle and check plate, the expansion direction and range of the foaming reaction are effectively controlled, avoiding unnecessary blockage, making the foaming process more controllable, and improving the construction efficiency and quality.

[0019] 2. The present invention provides a clear installation path for the heating pipe by arranging the pipe installation groove on the insulation brick body, reduces the adjustment work during laying, ensures the precise alignment of the pipe and the insulation brick, simplifies the construction process, and arranges the heating pipe inside the insulation block, which can effectively avoid direct damage to the heating pipe. The design of the brick cover accurately limits the expansion range of the polyurethane foam, avoids the waste caused by excessive expansion of the foam, and ensures that the foam can fully fill the narrow gap between the pipe holder and the brick cover, thereby improving the uniformity and integrity of the insulation effect. The convex block on the side end face of the brick cover and the L-shaped slide groove design on the side wall of the insulation brick body, through the combined action of sliding and lateral positioning, the brick cover and the insulation block form a stable interlocking connection, which is not only easy to operate, but also can be installed without complicated tools, greatly saving installation time and labor costs.

[0020] 3. A third spray can is arranged at the bottom of the brick cover of the present invention. The anti-corrosion coating inside the third spray can and the triangular layout formed by the first and second high-pressure spray cans constitute a stable elastic support system. When the heating pipe undergoes a thermal expansion and contraction cycle, the structure can provide necessary buffer space, reduce stress concentration caused by temperature changes, and avoid direct transmission to polyurethane foam or thermal insulation brickwork, thereby protecting the integrity of the entire insulation structure and the stability of the pipe interface. This design allows the pipe to have a slight displacement during thermal expansion and contraction without causing damage to the thermal insulation brickwork structure, reducing the deformation stress caused by temperature changes and ensuring the long-term safe operation of the pipeline system.

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 9 A heat-insulating brickwork structure for facilitating pipeline laying comprises a heat-insulating brickwork body 1, a pipeline installation groove 101 is provided at the upper end of the heat-insulating brickwork body 1, a pipeline fixing mechanism 2 is provided in the pipeline installation groove 101, and a brick cover 3 is provided on the top of the pipeline installation groove 101;

[0032] The pipeline fixing mechanism 2 includes a pipeline clamp 210, a first high-pressure spray can 201 and a second high-pressure spray can 202. The pipeline clamp 210 is fixedly mounted on the inner end surface of the pipeline mounting groove 101. The upper end surface of the pipeline clamp 210 is provided with a clamping groove 2101. The first high-pressure spray can 201 and the second high-pressure spray can 202 are fixedly mounted on the inner end surface of the clamping groove 2101. The first high-pressure spray can 201 contains a first mixed reagent, and the second high-pressure spray can 202 contains a second mixed reagent that can produce a foaming reaction with the first mixed reagent.

[0033] The brick cover 3 is detachably mounted on the top of the inner end surface of the pipeline installation groove 101 , and a third spray can 301 is arranged at the bottom of the brick cover 3 , and the third spray can 301 is provided with anti-corrosion paint.

[0034] Furthermore, a plurality of evenly arranged wing plates 203 are provided at the bottom of the side end surface and the lower end surface of the pipeline installation groove 101 , and the wing plates 203 are fixedly connected to the thermal insulation brickwork body 1 .

[0035] The contact area between the pipe holder 210 and the thermal insulation brickwork body 1 is enhanced by the wing plate 203, thereby improving the fixing strength of the pipe holder 210 and preventing the pipe holder 210 from shifting or loosening during use, thereby affecting the thermal insulation effect.

[0036] Furthermore, the pipe holder 210 is made of bent stainless steel sheets, the slot 2101 is an arc-shaped slot, and two groups of mutually symmetrical screw holes 204 are provided on the upper end surface of the bottom of the pipe holder 210. The outer end surfaces of the first high-pressure spray tank 201 and the second high-pressure spray tank 202 are both provided with external threads. The first high-pressure spray tank 201 and the second high-pressure spray tank 202 are respectively installed in the two groups of screw holes 204 and are threadedly connected to the pipe holder 210.

[0037] The pipe holder 210 made of stainless steel is not easy to corrode and has a certain elasticity, so that the heating pipe can be squeezed outward to clamp the top edge of the pipe fixing mechanism 2 into the pipe installation groove 101, and the first high-pressure spray tank 201 and the second high-pressure spray tank 202 at the bottom can be squeezed to spray reagents for foaming reaction.

[0038] Furthermore, the first high-pressure spray can 201 and the second high-pressure spray can 202 have the same structure, which includes a bottle body 2011, a sleeve 2018, a first spring 2013 and a pressure rod 2012. The sleeve 2018 is fixedly installed on the top of the bottle body 2011, the first spring 2013 is installed on the bottom of the sleeve 2018, the pressure rod 2012 is inserted into the sleeve 2018 and elastically connected to it through the first spring 2013, a suction pipe 2015 is provided at the bottom of the sleeve 2018, and the side wall of the pressure rod 2012 is provided with a nozzle 2017 and a feed hole 2016 that are interconnected.

[0039] When the pressure rod 2012 is pressed downward, the pressure rod 2012 moves downward, and when the feed hole 2016 slides into the sleeve 2018, the space inside the bottle body 2011 is connected with the external environment through the suction tube 2015, the sleeve 2018, the feed hole 2016 and the nozzle 2017, so that the first mixed reagent and the second mixed reagent in the bottle body 2011 are sprayed out under the action of the internal high-pressure air, so that they converge at the bottom of the pipe holder 210 to cause a foaming reaction, and quickly expand to fill the gap between the heating pipe and the pipe holder 210.

[0040] Furthermore, a support block 2014 is provided on the top of the pressure rod 2012, and the upper end surface of the support block 2014 is a curved surface structure. The angle between the nozzle 2017 and the central axis of the pressure rod 2012 is 30-45 degrees, and the nozzle 2017 is inclined downward.

[0041] The support block 2014 enhances the contact effect between the pipeline and the pressure rod 2012, improves the stability of the pipeline support, and prevents the pressure rod 2012 from being too sharp to pierce the heating pipeline. The downward-inclined nozzle 2017 structure allows the reagent sprayed by the nozzle 2017 to quickly flow to the center along the flow channel 205 on the upper end surface of the pipeline holder 210 for reaction.

[0042] Furthermore, a flow channel 205 for draining the first mixed reagent and the second mixed reagent is disposed on the upper end surface of the pipe holder 210 , and a reaction groove 206 is disposed at the center of the flow channel 205 . The flow channel 205 is an arc-shaped groove, and the reaction groove 206 is a spherical groove.

[0043] When the first mixed reagent and the second mixed reagent are sprayed out, they flow along the flow channel 205 into the reaction chamber for a foaming reaction, thereby expanding upward from the bottom of the heating pipe to fill the chamber, so that the foaming reaction is carried out at a specified position, thereby facilitating the control of the subsequent foaming expansion direction.

[0044] Furthermore, a baffle 207 protruding upward is provided at the upper end of the flow channel 205 , and a check plate 208 is provided in the reaction tank 206 .

[0045] The expansion direction of the foaming reaction is limited by the check plate 208, and the foamed reagent foam is guided upward to prevent it from expanding into the flow channel 205 and blocking the flow channel 205. The baffle 207 is used to prevent the upwardly expanding foam from covering the flow channel 205 and affecting the flow of the reagent, thereby affecting the subsequent foaming reaction rate, so that the foaming reaction can continue to proceed efficiently.

[0046] Furthermore, a protrusion 302 is provided on the side end face of the brick cover 3, and a slide groove 102 cooperating with the protrusion 302 is provided on the side wall of the pipe installation groove 101. The slide groove 102 is an L-shaped structure. A filling groove 303 is provided on the bottom of the brick cover 3, and the filling groove 303 is an isosceles trapezoidal structure.

[0047] When the brick cover 3 slides to the bottom of the slide groove 102 through the protrusion 302, it slides horizontally again, so that the protrusion 302 can resist the inner wall of the slide groove 102, and the brick cover 3 is interlocked with the insulation brickwork body 1, which is convenient for the installation of the brick cover 3, and the brick cover 3 can maintain a stable fit. After the brick cover 3 is covered on the pipe installation groove 101, the heating pipe can be insulated in all directions, and at the same time, the filling space of the foaming agent is limited. The foaming agent can fully fill the narrow gap between the pipe holder 210 and the brick cover 3 to ensure the insulation effect of the insulation block. The isosceles trapezoidal filling groove 303 structure allows the foaming agent to enter the filling groove 303 and solidify, so that the brick cover 3 can be more firmly fixed to the insulation brick block to prevent the brick cover 3 from slipping.

[0048] Furthermore, the third spray can 301 includes a pot body 3015, a piston rod 3011, a second spring 3014 and a pressure plate 3012. The piston rod 3011 is fixedly mounted on the upper end surface of the pressure plate 3012. The piston rod 3011 is inserted into the pot body 3015 and elastically slidably connected to it through the second spring 3014 and maintained sealed. The side wall of the pressure plate 3012 is provided with an atomizing nozzle 3016 that penetrates the top of the piston.

[0049] When the brick cover 3 is covered on the thermal insulation brickwork body 1, the heating pipe squeezes the pressure plate 3012, causing the piston to compress the space inside the kettle body 3015 upward, so that the anti-corrosion coating in the kettle body 3015 is sprayed out and sprayed to the surrounding polyurethane foam through the atomizing nozzle 3016, thereby enhancing the structural strength and anti-corrosion performance of the polyurethane and improving the service life of the thermal insulation brickwork.

[0050] Furthermore, the first mixed reagent includes polyurethane white material and a thickener, the second mixed reagent includes polyurethane black material and a surfactant, and the anti-corrosion coating is polyurea coating or acrylic coating.

[0051] When the black polyurethane material and the white polyurethane material come into contact, a foaming reaction quickly occurs to produce a large amount of polyurethane viscous foam, which is filled around the heating pipes. Both polyurea coatings and acrylic coatings have good weather resistance, wear resistance and waterproof properties, which can enhance the structural strength of polyurethane foam and slow down the corrosion rate of polyurethane foam under the action of condensed water. The durability of acrylic coatings is slightly lower than that of polyurea coatings, but it dries quickly and is easy to construct, so it can be flexibly selected according to construction needs.

[0052] When the thermal insulation brickwork is in use: according to the design drawings, the construction site is measured and marked to determine the specific location of the thermal insulation brickwork and the direction of the pipeline, the thermal insulation brickwork is placed on the base layer in a predetermined arrangement, and the heating pipe is pressed into the slot 2101 of the pipe holder 210. Under the elastic action of the pipe holder 210, the heating pipe squeezes the first high-pressure spray can 201 and the second high-pressure spray can 202 downward, so that the first and second mixed reagents are mixed and sprayed out, and converge in the reaction tank 206 along the flow channel 205, and a rapid foaming reaction occurs to fill the gap between the pipe and the holder. The brick cover 3 is first slid longitudinally to the bottom and then slid horizontally into place through the matching mechanism of the protrusion 302 and the slide groove 102 to ensure that the protrusion 302 is tightly combined with the inner wall of the slide groove 102. At this time, the third spray can 301 squeezes the top of the heating pipe, and the polyurea coating is automatically sprayed through the third spray can 301 to cover the newly formed polyurethane foam, thereby enhancing the anti-corrosion performance and allowing the foaming agent to fully solidify before laying its upper thermal insulation structure.

Both polyurea coatings and acrylic coatings have good weather resistance, wear resistance and water resistance, which can enhance the structural strength of polyurethane foam and slow down the corrosion rate of polyurethane foam under the action of condensed water. The durability of acrylic coatings is slightly lower than that of polyurea coatings, but it dries quickly and is easy to construct, so it can be flexibly selected according to construction needs.

[0074] When the thermal insulation brickwork is in use: according to the design drawings, the construction site is measured and marked to determine the specific location of the thermal insulation brickwork and the direction of the pipeline, and the thermal insulation brickwork is placed on the base layer in a predetermined arrangement. The heating pipe is pressed into the slot 2101 of the pipe holder 210. Under the elastic action of the pipe holder 210, the heating pipe squeezes the first high-pressure spray can 201 and the second high-pressure spray can 202 downward, so that the first and second mixed reagents are mixed and sprayed out, and converge in the reaction tank 206 along the flow channel 205, and a rapid foaming reaction occurs to fill the gap between the pipe and the holder. The brick cover 3 is first slid longitudinally to the bottom and then slid horizontally into place through the matching mechanism of the protrusion 302 and the slide groove 102 to ensure that the protrusion 302 is tightly combined with the inner wall of the slide groove 102. At this time, the third spray can 301 squeezes the top of the heating pipe, and the acrylic paint is automatically sprayed through the third spray can 301 to cover the newly formed polyurethane foam to enhance the anti-corrosion performance and allow the foaming agent to fully solidify before laying its upper thermal insulation structure.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
