Description

Technical Field

[0001] The present application relates to the field of construction engineering technology, and in particular to a thermal insulation, non-disassembly formwork and a manufacturing process thereof. Background Art

[0002] Most of the existing thermal insulation non-removal formwork uses thermal insulation materials such as polystyrene boards or rock wool as the core material, and composite cement pressure plates or calcium silicate boards on both sides. They have low compressive and tensile strengths and are prone to arching, formwork expansion, cracking and breakage during construction, affecting construction progress, quality and safety, and leaving hidden dangers for the safety of subsequent exterior walls. Moreover, the composite surface layers on both sides have no thermal insulation effect, affecting the overall thermal insulation effect of the thermal insulation non-removal formwork.

[0003] In this regard, Chinese patent document CN214614812U discloses a high-strength, low-thermal conductivity thermal insulation non-disassembly formwork, which improves the compressive and tensile strength of the thermal insulation non-disassembly formwork, reduces the thermal conductivity of the formwork, and eliminates the phenomena of formwork breakage, formwork expansion, etc. caused by insufficient formwork strength during construction; the thermal insulation non-disassembly formwork includes a three-dimensional grid and thermal insulation material, and the thermal insulation material is poured into the three-dimensional grid. The three-dimensional grid and the thermal insulation material are formed into an integrated structure through vibration compaction, wherein the two surface layers of the three-dimensional grid are spaced apart, and the two surface layers are connected by multiple vertical ribs. The three-dimensional grid is an integral structure. Therefore, during the vibration compaction process, the three-dimensional grid is easily deformed by force, which affects the overall strength of the thermal insulation non-disassembly formwork. Summary of the Invention

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A thermal insulation non-disassembly formwork comprises an insulation board, a first steel mesh embedded in the interior of the insulation board, and a second steel mesh embedded in the interior of the insulation board, wherein the first steel mesh is embedded in the upper layer of the insulation board, and the second steel mesh is embedded in the lower layer of the insulation board, the first steel mesh is parallel to the second steel mesh, the first steel mesh is connected to a plurality of first vertical ribs extending toward the second steel mesh, the second steel mesh is connected to a plurality of second vertical ribs extending toward the first steel mesh, and there is a gap between the first vertical ribs and the second vertical ribs, and the insulation board is formed by extrusion of an insulation material, and before the insulation material is extruded, the first steel mesh and the second steel mesh are both embedded in the insulation material.

[0007] Preferably, the insulation board has a center dividing surface parallel to the first steel mesh, the first steel mesh and the second steel mesh are respectively arranged on both sides of the center dividing surface, and the first steel mesh and the second steel mesh are both parallel to the center dividing surface, the first vertical reinforcement passes through the center dividing surface, and the second vertical reinforcement passes through the center dividing surface.

[0010] Preferably, the extension direction of the first vertical reinforcement is perpendicular to the first steel mesh, or the angle between the extension direction of the first vertical reinforcement and the first steel mesh is an acute angle; the extension direction of the second vertical reinforcement is perpendicular to the second steel mesh, or the angle between the extension direction of the second vertical reinforcement and the second steel mesh is an acute angle.

[0011] Preferably, the thermal insulation material is expandable polystyrene.

[0012] The present application also discloses a manufacturing process of a thermal insulation non-disassembly template, comprising the following steps:

[0013] S1, laying a first steel mesh sheet flat on the bottom of a mold box, supporting the first steel mesh sheet with a plurality of first support members so that a gap exists between the first steel mesh sheet and the bottom of the mold box, wherein the first steel mesh sheet is connected to a plurality of first vertical ribs, and the first vertical ribs extend in a direction away from the bottom of the mold box;

[0032] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] In the description of this application: the terms "upper" and "lower" refer to the upper and lower parts of the insulation board when it is placed horizontally; the terms "first" and "second" are intended to distinguish the objects referred to, and the terms "including", "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units that have been explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or equipment, or steps or units added based on further optimization schemes conceived in this application.

[0034] refer to Figure 1-3The present application discloses an insulation-free formwork, comprising an insulation board 1, a first steel mesh 2 embedded in the interior of the insulation board 1, and a second steel mesh 3 embedded in the interior of the insulation board 1, the first steel mesh 2 is embedded in the upper layer of the insulation board 1, and the second steel mesh 3 is embedded in the lower layer of the insulation board 1, the first steel mesh 2 is parallel to the second steel mesh 3, the first steel mesh 2 is connected with a plurality of first vertical ribs 21 extending toward the second steel mesh 3, the second steel mesh 3 is connected with a plurality of second vertical ribs 31 extending toward the first steel mesh 2, and there is a gap between the first vertical rib 21 and the second vertical rib 31, the insulation board 1 is formed by extrusion of the insulation material 5, and before the insulation material 5 is extruded, the first steel mesh 2 and the second steel mesh 3 are both embedded in the insulation material 5.

[0035] The first steel mesh 2 and the second steel mesh 3 embedded in the insulation board 1 are spaced from each other, and there is also a gap between the first vertical rib 21 and the second vertical rib 31. Therefore, the first steel mesh 2 and the second steel mesh 3 are not directly connected. In this way, when the insulation board 1 is in the process of extrusion molding, the first steel mesh 2 and / or the second steel mesh 3 are relatively displaced with the extrusion, and the first steel mesh 2 and the second steel mesh 3 are not in direct contact. In this way, the first steel mesh 2 and the second steel mesh 3 can be prevented from being squeezed and deformed, which affects the overall strength of the insulation non-disassembly formwork.

[0036] Here, it needs to be explained that, during the extrusion molding process, the extrusion direction is perpendicular to the first steel mesh 2. In the prior art, the three-dimensional grid is an integrated structure. In this way, the three-dimensional grid is squeezed from top to bottom, which easily causes the three-dimensional grid to deform. In the present application, the first steel mesh 2 and / or the second steel mesh 3 are separately arranged. During the extrusion molding process, the first steel mesh 2 and / or the second steel mesh 3 will only produce relative displacement, and will not be squeezed and deformed from each other.

[0037] refer to Figure 2-3 The insulation board 1 has a center plane 11 parallel to the first steel mesh 2. The first steel mesh 2 and the second steel mesh 3 are respectively arranged on either side of the center plane 11, and the first steel mesh 2 and the second steel mesh 3 are both parallel to the center plane 11. The first vertical reinforcement 21 passes through the center plane 11, and the second vertical reinforcement 31 passes through the center plane 11. When the insulation board 1 is placed horizontally, the center plane 11 is located between the upper and lower layers of the insulation board 1. The first vertical reinforcement 21 passes through the center plane 11, and the second vertical reinforcement 31 passes through the center plane 11. In this way, the overall strength of the insulation board 1 can be increased, that is, the shear strength of the insulation board 1 along the center plane 11 can be increased.

[0038] refer to Figure 1-3The first vertical rib 21 has a first bent section 211 integrally formed at one end away from the first steel mesh 2, perpendicular to the extension direction of the first vertical rib 21. The second vertical rib 31 has a second bent section 311 integrally formed at one end away from the second steel mesh 3, perpendicular to the extension direction of the second vertical rib 31. The first bent section 211 and the second bent section 311 increase the contact area between the first and second vertical ribs 21, 31 and the insulation board 1. The first bent section 211 is perpendicular to the first vertical rib 21, and the second bent section 311 is perpendicular to the second vertical rib 31. This makes it easier to firmly embed the first and second steel meshes 2, 3 into the insulation board 1, thereby increasing the tensile strength of the insulation board 1.

[0039] The first bending section 211 may also form an acute angle or an obtuse angle with the extension direction of the first vertical rib 21 , and the second bending section 311 may also form an acute angle or an obtuse angle with the extension direction of the second vertical rib 31 .

[0040] refer to Figure 1-4 The first steel mesh 2 is welded together with multiple steel bars arranged in a crisscross pattern, and the second steel mesh 3 is welded together with multiple steel bars arranged in a crisscross pattern. The first vertical bars 21 are welded to the intersections of the first steel mesh 2, and the second vertical bars 31 are welded to the intersections of the second steel mesh 3. The first vertical bars 21 can also be welded to other locations on the first steel mesh 2, and the second vertical bars 31 can also be welded to other locations on the second steel mesh 3.

[0041] The first vertical reinforcement 21 extends in a direction perpendicular to the first reinforcement mesh 2, or forms an acute angle between the first vertical reinforcement 21 and the first reinforcement mesh 2. The second vertical reinforcement 31 extends in a direction perpendicular to the second reinforcement mesh 3, or forms an acute angle between the second vertical reinforcement 31 and the second reinforcement mesh 3. The first vertical reinforcement 21 and the second vertical reinforcement 31 may also remain parallel.

[0042] The first vertical ribs 21 and the second vertical ribs 31 do not contact each other during the extrusion molding process of the thermal insulation board 1 .

[0043] The insulation material is expandable polystyrene.

[0044] The outer side of the insulation board is wrapped with an inorganic gelling material, which can improve the flame retardancy (combustion performance) of the insulation board.

[0045] The present application also discloses a manufacturing process of a thermal insulation non-disassembly template, comprising the following steps:

[0046] refer to Figure 5S1, lay the first steel mesh 2 flat on the bottom of the mold box 4, support the first steel mesh 2 by a plurality of first support members 6, so that there is a gap between the first steel mesh 2 and the bottom of the mold box 4, and connect the first steel mesh 2 with a plurality of first vertical ribs 21, which extend in a direction away from the bottom of the mold box 4;

[0047] refer to Figure 6 , S2, adding the thermal insulation material 5 into the mold box 4, and wrapping the first steel mesh 2 in the thermal insulation material 5;

[0048] refer to Figure 7 , S2, lay the second steel mesh 3 flat on the top of the thermal insulation material 5, and embed the second steel mesh 3 into the thermal insulation material 5, the second steel mesh 3 is connected to a plurality of second vertical ribs 31, the second vertical ribs 31 extend toward the bottom of the mold box 4, the second steel mesh 3 is parallel to the first steel mesh 2, and there is a gap between the second vertical ribs 31 and the first vertical ribs 21;

[0049] refer to Figure 8 and Figure 9 , S4, the top of the insulation material 5 is squeezed by the pressing plate 41, and the insulation material 5 is cooled after being squeezed to form the insulation board 1, and the height of the insulation material 5 is greater than the thickness of the insulation board 1.

[0050] The first support member 6 can be any object that supports the first steel mesh 2. After the insulation board 1 is formed, the first support member 6 can be taken out or retained in the insulation board 1. The insulation material 5 adopts a cold pressing process during the extrusion process.

[0051] The ratio of the height of the heat-insulating material 5 to the thickness of the heat-insulating board 1 is 1.6: 1. The heat-insulating material 5 is deformed by extrusion and shrinks in volume, and can be demoulded after cooling for 12 hours.

[0052] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
