[0031] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0032] In masonry construction, after installing the distribution box, cement mortar or fine aggregate concrete is needed to fill the area around the box shell, and the back of the box also needs to be reinforced. However, filling with mortar or fine aggregate concrete in one go is prone to shrinkage cracks and hollow areas, and the compactness of the filling is difficult to guarantee. In addition, due to non-standard operation by workers, the size of the reserved opening is often not up to standard. If the position of the reserved opening is off, the wall surface needs to be chiseled a second time, which affects the integrity of the masonry structure, wastes materials and labor, and pollutes the environment. Therefore, the installation quality of the distribution box directly affects the overall quality of the wall.

[0033] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0034] According to an embodiment of this utility model, a prefabricated component template is provided, taking an embedded electrical distribution box in a filler wall as an example, including:

[0035] Side plate 2 is adapted to be arranged horizontally around the outside of shell 4, and a molding space is formed between side plate 2 and the outer wall of shell 4. The molding space is adapted to be filled with concrete to form concrete frame 3.

[0036] The precast component template provided in this embodiment forms a concrete frame 3 by filling concrete between the shell 4 and the side plate 2. After removing the side plate 2, the shell 4 and the concrete frame 3 are used to form a precast component. This allows the shell 4 to be directly built on the wall during wall construction, thus avoiding the problems of shrinkage cracks and hollow areas that are easy to occur in the sealing mortar or fine stone concrete, and the difficulty in ensuring the compactness of the filling.

[0037] Specifically, the housing 4 is the outer shell of the distribution box. One side of the housing 4 has an opening. In a preferred embodiment, the housing 4 is inverted so that the opening faces downwards along the direction of gravity. Side plates 2 are arranged around the housing 4. After filling the space between the side plates 2 and the outer wall of the housing 4 with concrete, the concrete wraps around the outside of the housing 4 under gravity, and the concrete frame 3 and housing 4 form an integral precast component after the concrete has set. When constructing the wall, the precast component is directly built onto the corresponding wall, avoiding the need to seal the distribution box with mortar or fine aggregate concrete around and behind it, which can lead to shrinkage cracks, hollow areas, and difficulty in ensuring the compactness of the filling. This improves the quality of the wall. Furthermore, by forming an integral precast component from the concrete frame 3 and housing 4, construction standardization is promoted, controllability and construction efficiency are improved, and the need for secondary chiseling of the wall surface due to deviations in the reserved opening position is avoided, thus preventing repetitive labor. The precast components are directly laid on the wall during use, which is simple to operate, and the installation is completed in one go. There are no hidden quality problems later. In addition, the standardized templates for component production make it convenient to reuse and save materials.

[0038] In some embodiments, combined with Figure 1 andFigure 2 As shown, the projection of the side plate 2 covers the projection of the shell 4 in the horizontal direction.

[0039] The prefabricated component template provided by the embodiment is used to cover the shell 4 by the projection of the side plate 2, so that the concrete filling forms the concrete frame 3 to cover the side wall of the shell 4, thereby improving the stability of the combination of the concrete frame 3 and the shell 4.

[0040] As preferred, the top of the side plate 2 is higher than the top of the shell 4 in the direction of gravity, so that the concrete frame 3 covers the back of the distribution box when the distribution box is arranged in the inverted position. And by increasing the contact area of the concrete frame 3 and the shell 4, the connection stability of the concrete frame 3 and the shell 4 can also be increased. The concrete is filled in the forming space, and when the concrete is higher than the top L of the side plate 2, 1cm≤L≤1.5cm, the concrete pouring is stopped, the concrete is vibrated and compacted, and the concrete surface is flattened again before the concrete is finally cured.

[0041] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the prefabricated component template further comprises a limiting piece 6, which is located between the side plate 2 and the shell 4 and simultaneously abuts against the side plate 2 and the shell 4, and the limiting piece 6 is adapted to limit the relative position of the shell 4 and the side plate 2 in the horizontal direction.

[0042] The prefabricated component template provided by the embodiment is used to cover the shell 4 by the projection of the side plate 2, so that the concrete filling forms the concrete frame 3 to cover the side wall of the shell 4, thereby improving the stability of the combination of the concrete frame 3 and the shell 4.

[0043] Specifically, the limiting piece 6 comprises a wooden plate, a steel plate, and a plastic plate, and the limiting piece 6 simultaneously abuts against the mutually close side surfaces of the side plate 2 and the shell 4, so as to limit the horizontal displacement of the side plate 2 and the shell 4 during the process of concrete curing to form the concrete frame 3, thereby improving the standardization and controllability of the prefabricated component. Each side surface of the shell 4 is provided with a limiting piece 6, wherein the limiting piece 6 can be an integrated structure and is arranged around the shell 4, or the limiting piece 6 can be a single body and is arranged by multiple limiting pieces 6 to play a limiting role, and each side surface of the shell 4 is provided with at least one limiting piece 6 to ensure that the shell 4 is fixed during the concrete curing process.

[0044] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the prefabricated component template further comprises a bottom plate 1, which abuts against the lower end surface of the shell 4 in the direction of gravity; and the limiting piece 6 abuts against the bottom plate 1 and is arranged around the shell 4 once to form a plastering reserved space.

[0045] The prefabricated component template provided by the embodiment is characterized in that the limiting piece 6 is in abutment with the bottom plate 1 and is arranged around the shell 4, so as to form a reserved space for wall plastering.

[0046] As a preferred implementation form, the bottom plate 1 is arranged in the horizontal direction, and the side plate 2 and the lower end surface of the shell 4 are in abutment with the upper end surface of the bottom plate 1 at the same time. The limiting piece 6 is located at the lower part of the forming space between the side plate 2 and the shell 4 and is in abutment with the bottom plate 1, the side plate 2 and the shell 4 at the same time. Further, the limiting piece 6 can be directly placed on the bottom plate 1 and in abutment with the side plate 2 and the shell 4, or can be fixed on the bottom plate 1 by bolts or nails. The limiting piece 6 is arranged around the shell 4, which can not only limit the relative position of the side plate 2 and the shell 4 in the horizontal direction, but also block the concrete, so as to form a reserved space for later wall plastering in the area close to the opening end of the side wall of the shell 4. According to the size classification and statistical data of the residential indoor distribution box in the design drawing, the size of the bottom plate 1, the side plate 2 and the limiting piece 6 can be determined, so as to process prefabricated components that meet the size specifications.

[0047] In some embodiments, in combination with Figure 1 and Figure 2 As shown in the drawings, the thickness of the limiting piece 6 is H in the direction perpendicular to the main plane of the bottom plate 1, wherein 10mm≤H≤15mm.

[0048] The prefabricated component template provided by the embodiment is characterized in that the thickness of the limiting piece 6 is greater than or equal to 10mm and less than or equal to 15mm, so as to ensure that the thickness of the wall plastering meets the requirements.

[0049] Preferably, the thickness of the limiting piece 6 is 12mm, so as to ensure that the plastering thickness near the distribution box can meet the requirements when the wall is plastered after the concrete frame 3 and the shell 4 are built on the wall.

[0050] In some embodiments, in combination with Figure 1 and Figure 2 As shown in the drawings, the side of the side plate 2 away from the shell 4 is provided with a clamping piece, and the clamping piece is adapted to prevent the side plate 2 from moving away from the shell 4.

[0051] The prefabricated component template provided by the embodiment is characterized in that the clamping piece is arranged on the outside of the side plate 2, which is conducive to ensuring the stability of the side plate 2 during the concrete setting process.

[0052] Specifically, the clamping piece is adapted to limit the outer wall of the side plate 2, so as to prevent the side plate 2 from moving away from the shell 4 during the concrete setting process, thereby facilitating the standardization and controllability of the overall component of the concrete frame 3 and the shell 4.

[0053] In some embodiments, in combination with Figure 1and Figure 2 As shown in the drawings, the clamping member includes a plurality of clamps.

[0054] Specifically, the clamping member is a clamp, and the side plate 2 is limited and fixed by the clamp away from the side of the shell 4. At least one wooden block can be arranged between the clamp and the side plate 2, so as to increase the force area of the clamp on the side plate 2 and improve the reliability of the limiting.

[0055] In addition, the clamping member can also be a rope, which is bound to the side of the side plate 2 away from the shell 4, so as to limit the side of the side plate 2 away from the shell 4. The clamping member can also be a steel pipe or a steel bar, which is welded to form a fixing clamp around the side of the side plate 2 away from the shell 4.

[0056] In some embodiments, in combination with Figure 1 and Figure 2 As shown in the drawings, a threading hole is formed in the side wall of the shell 4, and a blocking member 5 is arranged between the side plate 2 and the shell 4 corresponding to the threading hole. The blocking member 5 is adapted to prevent the concrete frame 3 from covering the threading hole.

[0057] The prefabricated component template provided in the embodiment prevents the concrete from plugging the threading hole by arranging the blocking member 5 at the position corresponding to the threading hole between the side plate 2 and the shell 4.

[0058] Specifically, along the axis direction of the threading hole, the projection of the blocking member 5 covers the threading hole, and the blocking member 5 simultaneously abuts against the sides of the side plate 2 and the shell 4 close to each other, so as to prevent the concrete frame 3 from shielding the threading hole in the axis direction of the threading hole. The thermal insulation strip can be further filled in the threading hole to plug the threading hole.

[0059] In some embodiments, in combination with Figure 1 and Figure 2 As shown in the drawings, the blocking member 5 includes an XPS thermal insulation plate (extruded polystyrene foam plastic for heat insulation).

[0060] Specifically, the blocking member 5 includes an XPS thermal insulation plate, a wooden plate, a steel plate, and a plastic plate, and the blocking member 5 is adapted to form a blocking position for the concrete.

[0061] In some embodiments, in combination with Figure 1 and Figure 2 As shown in the drawings, a release agent layer is arranged on the side of the side plate 2 facing the shell 4.

[0062] The prefabricated component template provided in the embodiment arranges a release agent layer on the side of the side plate 2 facing the shell 4, so as to facilitate the removal of the side plate 2 later.

[0063] Specifically, release agent is applied on the side surface of the side plate 2 close to the shell 4, and release agent is applied on the side surface of the limiting member 6 and the blocking member 5 in contact with the concrete frame, so as to facilitate the disassembly of the prefabricated formwork after the concrete coagulates into the concrete frame 3, thereby facilitating the prefabricated component formed by the concrete frame 3 and the shell 4.

[0064] Obviously, the above embodiments are only examples for clearly illustrating, but not limit the embodiments. Although the embodiments of the present application are described in conjunction with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope of the present application.
