DETAILED DESCRIPTION

[0051] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thoroughly and completely understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0052] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the general meaning understood by those skilled in the art to which the present application belongs.

[0053] The modular assembly system is an assembly construction with box modules having independent functions as units. Compared with the traditional component assembly system, the modular assembly can realize factory production, integrated decoration, and improve the level of building industrialization. In addition, the high integration of the module also greatly reduces the construction process on site, reduces the emission of waste on site, and significantly improves the construction efficiency and green level. Therefore, the modular assembly system is more in line with the requirements of new building industrialization, and the research on the modular assembly system is also more conducive to the development of new building industrialization.

[0054] At present, the modular building of the concrete box mode significantly improves the construction efficiency due to its high integration. It supports and forms the post-cast concrete by taking the wall form as a removable formwork, which can maintain the position and shape of the concrete before it hardens and forms.

[0055] However, the co-action of the wall form and the post-cast concrete is not considered in the design, the wall form is not taken into account in the strength of the shear wall, and the wall form and the steel structure inside the shear wall do not cooperate, which makes it still need to perform a large amount of binding operation on the steel bars before pouring work in the wall form, not only the work efficiency is low, but also a large amount of waste is generated due to the steel bar binding work, which affects the green level.

[0056] The technical solution of the embodiment of the present application is to solve the above technical problems, and the general idea is as follows:

[0057] Embodiment 1

[0058] Reference is made to the accompanying drawings Figure 1 and the accompanying drawings Figure 2The inner wall prefabricated component provided by the embodiment comprises a first formwork 1 and a second formwork 2; a plurality of first truss steels 3 are arranged on a first surface of the first formwork 1 along a first direction a and extend along a second direction b; the first truss steels 3 are anchored in the first formwork 1 towards a first end of the first formwork 1 along a third direction c and are provided with first connecting pieces 5 away from a second end of the first formwork 1; a plurality of second truss steels 4 are arranged on a second surface of the second formwork 2 along the first direction a and extend along the second direction b; the second truss steels 4 are anchored in the second formwork 2 towards a first end of the second formwork 2 along the third direction c; the second formwork 2 is provided with second connecting pieces 6 for detachably connecting the first connecting pieces 5;

[0059] The first surface of the first formwork 1 and the second surface of the second formwork 2 are opposite to each other, and the first connecting pieces 5 and the second connecting pieces 6 are connected, so that a pouring space is formed between the first formwork 1 and the second formwork 2; the first truss steels 3 and the second truss steels 4 are alternately arranged along the first direction a, the second truss steels 4 extend at least into the pouring space away from the second end of the second formwork 2 along the third direction c, and the first truss steels 3 abut against the second surface of the second formwork 2 away from the second end of the first formwork 1 along the third direction c; the first direction a and the second direction b are parallel to the first surface of the first formwork 1 and the second surface of the second formwork 2, and the first direction a and the second direction b are perpendicular to each other; and the third direction c is perpendicular to the first surface of the first formwork 1 and the second surface of the second formwork 2.

[0060] It can be understood that, in order to solve the problem that the existing wall formwork only has a shaping effect with the shear wall, resulting in low construction efficiency and waste discharge at the construction site, the inner wall prefabricated component provided by the embodiment, as a shared inner wall component of adjacent rooms, realizes assembly of the first formwork 1 and the second formwork 2 to form an integrated wall formwork structure through detachable connection of the first connecting pieces 5 on the first truss steels 3 and the second connecting pieces 6 on the second formwork 2, and realizes anchoring connection of the first truss steels 3 and the second truss steels 4 with the post-poured concrete, so that the concrete, the steel bars and the two formworks form an integrated wall structure to bear loads together to meet the functional requirements of buildings, not only improve the strength and shear resistance of the final wall, but also cancel the steel bar binding work on site through prefabrication, simplify the assembly process, greatly reduce the waste discharge on site, and improve the green level.

[0061] The inner wall prefabricated component provided in the embodiment can be, but is not limited to, a prefabricated part of a modular assembly wall, for example, a prefabricated part of an inner wall of an environmental residential house, which can face the indoor environment when used or built, and can be a wall shared by two adjacent rooms. In the embodiment, the first direction a, the second direction b and the third direction c are perpendicular to each other. In actual construction, the first direction a and the second direction b are the length direction and the height direction of the wall respectively, and the third direction c is the thickness direction of the wall.

[0062] The first mold shell 1 and the second mold shell 2 are rigid structures, which can be, but are not limited to, plate structures, and can be prepared on an automatic steel mold platform turning device using concrete, molten metal or the like. The first mold shell 1 and the second mold shell 2 can be the same or different, as long as they can form a pouring space when they are opposite. In actual assembly, the first mold shell 1 and the second mold shell 2 can be integrally connected to form an integrated wall mold by the cooperation of the first connecting piece 5 and the second connecting piece 6. The pouring space between the first mold shell 1 and the second mold shell 2 is used for pouring concrete on site to form a stable modular assembly wall. When transported, the first mold shell 1 and the second mold shell 2 can be relatively independent, which is convenient for transportation and saves space. In the following description of the embodiment, the first mold shell 1 and the second mold shell 2 both face the indoor environment. In the embodiment, the inner wall prefabricated component can be combined with an outer decorative piece, a sound insulation layer and the like to form a composite mold shell structure, and a steel mesh can also be arranged inside the mold shell. High-strength concrete can also be used to enhance the structural strength and load-bearing capacity of the mold shell. According to design experience or habit, combined with the thickness of the modular assembly wall and the diameter of the main steel bars in the wall, for a certain type of environmental ordinary high-rise concrete building wall, the size of the first mold shell 1 and the second mold shell 2 in the third direction c is at least 25 mm, for example, 25 mm, 30 mm.

[0063] The first truss steel bars 3 and the second truss steel bars 4 are both rigid structures, and can be composed of multiple steel bars. The first truss steel bars 3 and the second truss steel bars 4 can disperse and transfer loads between the first formwork 1 and the second formwork 2, between the two formworks and the post-cast concrete, and improve the load bearing capacity and rigidity of the structure. The first truss steel bars 3 and the second truss steel bars 4 can be linear in the second direction b, or can be non-linear. The two ends of the first truss steel bars 3 and the second truss steel bars 4 in the third direction c can be of any shape, such as pointed, ring-shaped, bent, etc., to improve the anchoring strength with the first formwork 1 and the second formwork 2 and the post-cast concrete. The first truss steel bars 3 and the second truss steel bars 4 in the third direction c can be linear, bent, etc. The first truss steel bars 3 and the second truss steel bars 4 in the third direction c can be parallel to the straight line in which the third direction c is located, or can be inclined at a specified angle with the third direction c, etc. In the embodiment, one end of the first truss steel bars 3 is anchored to the first formwork 1 and prepared and installed with the first formwork 1. One end of the second truss steel bars 4 is anchored to the second formwork 2 and prepared and installed with the second formwork 2. After the first formwork 1 and the second formwork 2 are connected by the first connecting piece 5 and the second connecting piece 6, part of the structure of the first truss steel bars 3 and part of the structure of the second truss steel bars 4 are placed in the pouring space, so that the post-cast concrete can form an integrated prefabricated wall body with the two formworks through part of the structure of the second truss steel bars 4 and part of the structure of the first truss steel bars 3. The two formworks no longer only have the function of removable formwork, but also bear loads and disperse forces together with the steel bars and the concrete, to improve the strength, rigidity and shear resistance of the modular assembly wall. At the same time, the first truss steel bars 3 and the second truss steel bars 4 are prefabricated in the corresponding formworks before the post-concrete, and the binding work of the wall steel bars is omitted on site, greatly improving the on-site assembly efficiency. The anchoring ends of the first truss steel bars 3 and the second truss steel bars 4 can be anchored during the preparation of the first formwork 1 and the second formwork 2. For example, referring to the attached Figure 7 A pad d is arranged at the first end of the first truss steel bars 3 along the third direction c, the first truss steel bars 3 are raised to a certain height, and then the concrete of the first formwork 1 is poured to anchor the pad d and the first end of the first truss steel bars 3 synchronously. Referring to the attached Figure 13In the second truss steel bar 4, a pad d is arranged at one end of the third direction c, and the second truss steel bar 4 is raised to a certain height by the pad d, and then the pouring of the second formwork 4 is carried out to anchor the pad d and the first end of the second truss steel bar 4 synchronously. In this embodiment, the part anchored in the first formwork 1 and the second formwork 2 can be arranged to have a certain size in the first direction a and the second direction c, so that the truss steel bar can be tightly connected with the inside of the formwork to ensure the anchoring strength, that is, to ensure that the first truss steel bar 3 and the second truss steel bar 4 will not be pulled out of the formwork during construction or use, and to improve the overall structural strength of the inner wall prefabricated component. It is not difficult to understand that the side of the second truss steel bar 4 facing the first formwork 1 can be placed in the pouring space, for example, at the midpoint of the pouring space in the third direction c, or can be in contact with the first formwork 1. The design can be adjusted according to the actual strength and cost requirements, and will not be described in detail here.

[0064] In the first connecting piece 5 and the second connecting piece 6, the first connecting piece 5 and the second connecting piece 6 can be structural members in the form of screw connection, clamping connection, adhesive connection, hooking connection, etc. The first connecting piece 5 is arranged at the end of the first truss steel bar 3 away from the first formwork 3, and then when the pouring space is formed, the first connecting piece 5 is closest to the second formwork 2, so that the connection with the second connecting piece 5 can be easily carried out from the side of the second formwork 2. In this embodiment, the arrangement position and number of the first connecting piece 5 can be designed and adjusted according to actual needs, for example, referring to the drawings Figure 1 and the drawings Figure 4 The first connecting piece 5 can be arranged at part of the positions of the end of the first truss steel bar 3 away from the first formwork 1, or all the first ends can be provided with the first connecting piece 5.

[0065] According to the above, the inner wall prefabricated component provided by the present application realizes the detachable connection of the first formwork 1 and the second formwork 2 by arranging the first connecting piece 5 on the first truss steel bar 3 to cooperate with the second connecting piece 6 on the second formwork 2, realizes the preparation of the integrated wall mold, and improves the assembly convenience of the inner wall prefabricated component shared between adjacent rooms; the connection strength of the integrated prefabricated wall formed by the integrated wall mold and the post-poured concrete is enhanced by the arrangement of the first truss steel bar 3 and the second truss steel bar 4, and the alternately arranged first truss steel bar 3 and second truss steel bar 4 can enhance the interfacial shear resistance between the post-poured concrete and the wall mold. Not only can the strength of the formwork be taken into account in the strength of the overall modular wall, but also the on-site steel bar binding operation can be avoided, the efficiency can be improved, and the waste emission caused by on-site binding can be effectively reduced; thereby solving the problem that the existing wall mold and shear wall only have a shaping effect, resulting in low construction efficiency and waste emission at the construction site.

[0066] Further, referring to the drawings Figure 1 and the drawings Figure 2The first connecting piece 5 and the second connecting piece 6 are screwed to each other.

[0067] It can be understood that, in order to realize the detachable connection of the first connecting piece 5 and the second connecting piece 6, the two can be arranged in a screwed relationship in the embodiment, for example, referring to the drawings, the first connecting piece 5 and the second connecting piece 6 are screwed to each other. Figure 3 and the drawings Figure 9 A nut structure is arranged on the side of the first truss steel bar 3, and an opening or a threaded hole corresponding to the position of the nut is formed on the second formwork 2, so that the assembly of the two formworks can be completed by a screw rod or a bolt outside the second formwork 2, improving the convenience; at the same time, the stability of the screw connection is relatively high, which can effectively maintain the relative position relationship of the first formwork 1 and the second formwork 2 before the operation of the post-cast concrete. It can be understood that, before pouring the second formwork 2, a hole-forming filler such as ESP foam needs to be prevented from being removed at the corresponding position, and after the hole-forming filler is removed after pouring, the corresponding opening or threaded hole can be formed at the position.

[0068] Further, referring to the drawings Figure 1 and the drawings Figure 2 The inner wall prefabricated component provided by the embodiment further comprises a connecting steel bar 7 in the specific implementation, one end of the first truss steel bar 3 in the second direction b is provided with at least two connecting steel bars 7 in the third direction c, the connecting steel bar 7 extends out of the first formwork 1 along the second direction b or the opposite direction of the second direction b, and is used for being inserted into the pouring space of the inner wall prefabricated component adjacent to the inner wall prefabricated component where the connecting steel bar 7 is arranged.

[0069] It can be understood that, in order to realize the matching assembly of the multi-piece inner wall prefabricated component, the connecting steel bars 7 are arranged in the embodiment, which can be prefabricated in the inner wall prefabricated component along with the first truss steel bars 3, improve the on-site assembly efficiency, for example, welding or binding; the connecting steel bars 7 can also be bound on the first truss steel bars 3 on site, ensure the uniformity of the inner wall prefabricated component and the transportation convenience, and prevent the protruding connecting steel bars 7 from affecting the transportation. During on-site assembly, the connecting steel bars 7 can be connected to the upper end of the lower inner wall prefabricated component, and then the lower inner wall prefabricated component is poured, the upper inner wall prefabricated component is hoisted and connected to the connecting steel bars 7 at the upper end of the upper inner wall prefabricated component, and then the upper inner wall prefabricated component is poured, and so on. In the embodiment, the connecting steel bars 7 can be in a linear form, a bent form or the like, as long as they can meet the lap length requirement in the second direction b corresponding to the upper and lower adjacent two inner wall prefabricated components, that is, not less than the seismic anchorage length of the longitudinal tensile steel bar, that is, the extension length of the connecting steel bars 7 in the second direction b in the upper and lower adjacent two inner wall prefabricated components is not less than the seismic anchorage length of the longitudinal tensile steel bar. This reference setting is easily understood by those skilled in the art, and will not be described here. Correspondingly, in order to realize the connection of the adjacent inner wall prefabricated components in the first direction a, steel bar structures extending out of the pouring space in the first direction a can be arranged on the formwork or truss steel bars in the embodiment. Similarly, the extension length and the length reserved in the pouring space should meet the lap length requirement.

[0070] In the embodiment, at least two connecting steel bars 7 are arranged in the third direction c at one end of the first truss steel bars 3 in the second direction b, that is, the downward end during actual assembly, for example, referring to FIG. 1, the connecting steel bars 7 are arranged at the lower end of the first truss steel bars 3 in the second direction b. Figure 2 The connecting steel bars 7 can be bound or welded with the first truss steel bars 3, and the two connecting steel bars 7 can also be bound. The number of connecting steel bars 7 can be designed and adjusted according to actual needs, which is not limited here. It is not difficult to understand that the other end of the first truss steel bars 3 in the opposite direction of the second direction b, that is, the upward end during actual assembly.

[0071] Further, referring to FIGS. 1, 2, 3, 4, 5 and 6, Figure 3 , FIG. 1, Figure 4 , FIG. 2, Figure 5 , FIG. 3, Figure 6In the embodiment, the first truss steel bar 3 comprises a first steel bar 31, a second steel bar 32 and a top chord steel bar 33; the top chord steel bar 33 extends along the second direction b, and the first steel bar 31 and the second steel bar 32 are symmetrically arranged on both sides of the top chord steel bar 33 along the first direction a; the first steel bar 31 and the second steel bar 32 are continuously bent along the second direction b to form a plurality of first tie segments 34 arranged at intervals along the second direction b at one end of the first formwork 1; and at least the first tie segment 34 of the first truss steel bar 3 is anchored in the first formwork 1.

[0072] It can be understood that, in order to ensure the anchoring strength of the first truss steel bar 3 and the first formwork 1, the first truss steel bar 3 is arranged in the form of comprising the first steel bar 31, the second steel bar 32 and the top chord steel bar 33 in the embodiment; the top chord steel bar 33 is a straight steel bar, which can be connected with the first steel bar 31 and the second steel bar 32 at the same time, which can be but is not limited to welding or binding, so as to ensure the overall strength of the first truss steel bar 3. Figure 4 It can be understood that, in order to ensure the anchoring strength of the first truss steel bar 3 and the first formwork 1, the first truss steel bar 3 is arranged in the form of comprising the first steel bar 31, the second steel bar 32 and the top chord steel bar 33 in the embodiment; the top chord steel bar 33 is a straight steel bar, which can be connected with the first steel bar 31 and the second steel bar 32 at the same time, which can be but is not limited to welding or binding, so as to ensure the overall strength of the first truss steel bar 3.
