Description

Technical Field

[0001] This invention relates to the field of new building materials technology, and in particular to a method for manufacturing a split-type EPS non-disassembly modular unit and a precast cement inner panel. Background Technology

[0002] Existing EPS cavity modules in the construction field, such as Figure 1 As shown, it consists of an EPS foam board 1' and a steel bar 2' connected in the middle. The two ends of the steel bar 2' are connected to the EPS foam board 1' via embedded seats 3'. The EPS foam board 1' serves as both a formwork for pouring concrete and as a thermal insulation layer for the wall. During construction, concrete is poured into the cavity, and the surface is plastered to form a composite wall with good thermal insulation performance, which has been widely used in vast rural areas.

[0003] Existing EPS cavity modules used in building walls have inner and outer panels made of molded EPS foam boards, with a fire rating of B1 or B2, which cannot reach Class A fire resistance. Therefore, they cannot be directly used in the construction of buildings with higher fire safety requirements. Furthermore, when EPS foam boards are used as interior panels, the bonding strength between them and subsequent interior finishing materials such as plaster or wall panels is generally low, making them prone to detachment.

[0004] To overcome the above problems, a method for manufacturing a split-type EPS modular assembly without disassembly and a precast cement inner panel is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a modular EPS assembly module that does not require disassembly. It uses a modular external insulation board and a precast cement inner board as templates for pouring concrete, which improves the fire resistance rating and facilitates subsequent interior decoration work.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a split-type EPS (Expanded Polystyrene) modular assembly, comprising an outer insulation board, outer anchors, connectors, inner anchors, and a precast cement inner slab. The outer insulation board and the precast cement inner slab are arranged parallel and aligned. The outer anchors are disposed on the inner sidewall of the outer insulation board, which is made of EPS foam board material. The inner anchors are disposed on the inner sidewall of the precast cement inner slab. The connectors are vertically and detachably inserted between the outer anchors and the inner anchors. Two or more connectors are disposed perpendicular to the outer insulation board within the cavity.

[0007] The use of precast cement panels to replace the original EPS foam boards is a significant innovation in this application and a key technical means to achieve fire protection requirements.

[0008] Further, the outer anchor includes an inner anchor plate, a vertical connecting plate, a surface plate and a slot part one, the vertical connecting plate is a hollow plate and is centrally arranged between the inner anchor plate and the surface plate; the surface plate is attached to the inner side wall of the external thermal insulation board; two or more than two slot part ones are arranged on the outer wall of the surface plate in a staggered manner, and the end of the connecting piece is inserted into the slot part one.

[0009] Further, the inner anchor includes a slot part two, two or more than two slot part twos are arranged on the outer wall of the inner anchor body in a staggered manner; the main plate of the connecting piece is integrally provided with a plug strip at both ends, and the plug strip can be plugged into the slot part one or the slot part two.

[0010] Further, the left and right side walls of the cement prefabricated inner plate are respectively provided with a recess and a protrusion connected by a tongue and groove; a bottom recess is centrally formed on the bottom wall of the cement prefabricated inner plate, and a top protrusion is centrally arranged on the top wall of the cement prefabricated inner plate and is adapted to the upper adjacent cement prefabricated inner plate.

[0011] Further, the bottom recess is a circular arc recess, and the top protrusion is an arc top protrusion.

[0012] Further, it also includes a steel mesh and a pre-embedded plate, the steel mesh is embedded in the cement prefabricated inner plate, and the pre-embedded plate is half-embedded on the inner side wall of the cement prefabricated inner plate; the steel mesh is welded to the large inner side wall of the pre-embedded plate, and the inner anchor is welded to the outer side wall of the pre-embedded plate.

[0013] How to arrange the inner anchor on the thin cement prefabricated inner plate is a technical difficulty in the application, which needs to ensure the anchoring strength and avoid breakage.

[0014] Further, the number of the pre-embedded plate and the inner anchor is consistent and one-to-one corresponding; the profile area of the pre-embedded plate is larger than that of the inner anchor.

[0015] Further, it also includes a fiber mesh, which is impregnated and laid on the outer side wall of the cement prefabricated inner plate.

[0016] The application also discloses a method for manufacturing a cement prefabricated inner plate, which is formed by pouring and curing in a mold, and the bottom shell of the pouring mold is provided with an embedded recess for placing the pre-embedded plate.

[0017] Further, the thickness of the pre-embedded plate is greater than the depth of the embedded recess, and the steel mesh is suspended on the top surface of the pre-embedded plate.

[0018] The manufacturing method of the cement prefabricated inner plate is an important improvement work of the applicant, and the cement prefabricated inner plate meeting the requirements is successfully manufactured.

[0019] Compared with the prior art, the present application has the beneficial technical effects: The split EPS non-disassembly combination module of the present application realizes the connection of the external thermal insulation board and the cement prefabricated inner board during installation and separation during transportation, reduces the occupied carriage space and saves the transportation cost; compared with the prior art in which the EPS foam board is used as the inner board and the outer board, the present application uses the cement prefabricated inner board for the first time, which achieves the A-level fireproofing requirement on the one hand and increases the strength of the indoor side of the wall on the other hand, facilitating the installation of the interior decoration material in the later stage. The present application uses the split external thermal insulation board and cement prefabricated inner board as the formwork for pouring concrete, which improves the fireproofing level and is also convenient for the indoor decoration work in the later stage.

[0020] In addition, by setting the outer anchor to a horizontal cross-section H-shaped structure, the anchoring strength to the EPS foam board material is increased, and the strength of the outer anchor itself is also large; by setting the slot part one or the slot part two to a T-shaped slot opening upward, the installation of the connecting piece from top to bottom is facilitated; the two connecting pieces separated upward and downward are installed on the same outer anchor, and the disassembly and assembly are more flexible and convenient. By additionally arranging grooves and protrusions on the left and right side walls, bottom grooves and top protrusions on the bottom wall and the top wall, the tongue-and-groove connection during the assembly of adjacent cement prefabricated inner boards can be realized, and the heat bridge heat transfer at the joint is reduced compared with the straight seam. By setting the bottom groove and the top protrusion to a matching circular arc profile, the automatic centering effect can be achieved. By additionally arranging the steel mesh sheet, the strength of the cement prefabricated inner board is increased, and the breaking of the cement prefabricated inner board is less likely to occur; by welding the embedded plate to the steel mesh sheet and welding the inner anchor to the embedded plate, the in-place position of the inner anchor can be flexibly adjusted, and the connection strength is more firm and reliable compared with the direct embedding method. By additionally arranging the fiber mesh cloth on the side wall of the cement prefabricated inner board facing the indoor side, the drilling and edge breaking during the installation of the interior decoration material can be reduced, and the installation strength and anti-falling performance are improved.

[0021] The cement prefabricated inner board manufacturing method of the present application can position the embedded plate before pouring by arranging the embedded plate embedding groove on the bottom shell of the pouring mold, so as to avoid the offset and misalignment of the embedded plate. By reasonably arranging the thickness of the embedded plate and padding the steel mesh sheet, the steel mesh sheet can be centrally arranged in the cement prefabricated inner board, so as to avoid the deflection and exposure of the framework.

[0031] In a specific embodiment of the present embodiment, as shown in Figure 5 and Figure 6 , the outer anchor 2 includes an inner anchor plate 201, a vertical connecting plate 202, a surface plate 203 and a slot part one 204, the vertical connecting plate 202 is a hollow plate and is centrally arranged between the inner anchor plate 201 and the surface plate 203, and actually the horizontal cross section of the outer anchor 2 is a H-shaped structure.
