Description

Building embedded member and building structure

Technical Field

The utility model relates to a structure of building embedded component, especially the structure of building embedded component of multiplicable anchor power.

Background

In the construction process of a reinforced concrete structure (whether a precast reinforced concrete structure or a non-precast reinforced concrete structure) of a general building, after reinforcement binding operation is completed, a template structure needs to be constructed for subsequent concrete pouring operation. Wooden forms are mostly used in the conventional construction mode, but with the evolution of material technology, different kinds of form materials are available for civil engineering construction work, such as steel forms, plastic forms or aluminum forms. Among them, the use of aluminum forms has been increasing in recent years because the aluminum forms have a lower weight than steel forms and are lighter in weight for ease of construction. The smoothness and the flatness of the surface of the reinforced concrete constructed by the aluminum template are higher than those of the traditional wood template, and the aluminum template can be reused for a relatively high number of times. In addition, wood is not needed in the construction process of using the aluminum formwork, so that the construction site can be kept clean and engineering wastes can be reduced. Although the cost of aluminum forms is somewhat higher than that of conventional wooden forms, they are not comparable to conventional wooden forms, regardless of the appearance quality of the finished building product and the advantage of being recyclable many times. The above advantages make the construction of reinforced concrete structures using aluminum formworks a widely used construction method, both in the construction site and in the precast plants.

In order to construct a reinforced concrete structure, after the work of binding reinforcing bars and constructing aluminum formworks is completed at a construction site or a precasting factory and before the work of pouring concrete, a pre-piping work must be completed, so that after the reinforced concrete structure is completed, various internal wiring pipes are provided in the structure to enable the work of arranging, for example, water and electricity pipelines, public pipelines or strong/weak electric systems. The distribution lines in reinforced concrete structures often require the use of certain pre-embedded components for specific joints or for junction fittings, including components such as electrical junction boxes, elbows, floor joints, beam-through bushings, beam-through bushing blocks, or hangers. The embedded member is fixed to a predetermined position in the reinforced concrete structure, and usually has a portion exposed on the surface of the reinforced concrete structure. In other words, the embedded member is not completely embedded in the reinforced concrete structure, but is partially exposed and accessible outside the reinforced concrete structure, and further construction work such as piping or wiring is performed. Therefore, when these embedded members are fixed at predetermined positions, it is necessary that a part of the embedded members closely contact the aluminum formwork and do not shift or cause grout leakage when the grouting work is performed. Therefore, after the grouting operation is completed and the mold is removed, the embedded member can be positioned at the preset position matched with the drawing and can be used.

The conventional method for fixing the embedded member is, for example, to fix the embedded member to an aluminum form with self-tapping screws, then to lay and fix the embedded member to the reinforcing steel bars with iron wires, then to remove the self-tapping screws before grouting, then to remove the aluminum form after concrete pouring to expose the embedded member to the outside of the reinforced concrete structure. Another way is to drill a plurality of through holes at the predetermined positions for fixing the embedded members on the aluminum formwork, and to pass iron wires through the through holes for fixing of the embedded members themselves and through the corresponding through holes of the aluminum formwork, and then the constructor winds the iron wires respectively to fix the embedded members at the predetermined positions above the aluminum formwork. And after the embedded member is fixed above the aluminum template, grouting operation is carried out. The conventional construction method has a disadvantage of complicated steps, and particularly, the method of fixing the embedded members by using the iron wires not only needs to perform the construction operation of fixing the embedded members respectively on the upper and lower surfaces of the aluminum formwork, but also must loosen or cut the wound iron wires below the surface of the aluminum formwork to perform the operation of removing the aluminum formwork.

As can be seen from the above, the conventional construction method for embedding and attaching the embedded member in the reinforced concrete structure is complicated, and cannot meet the requirement of rapid construction of the existing building. In addition, because the part of the embedded component is exposed outside the reinforced concrete structure and is positioned in the reinforced concrete structure after the reinforced concrete structure is completed, the anchoring force of the embedded component in the reinforced concrete structure is large, and the embedded component can be stably embedded in the reinforced concrete structure for a long time and cannot be loosened due to long-term use or external force, so that great influence is caused.

In view of the above, how to improve the embedded member to increase the anchoring force between the embedded member and the reinforced concrete structure, so that the embedded member can be stably and fixedly maintained in the reinforced concrete structure for a long time to increase the service life, how to fix the embedded member on the aluminum formwork in a rapid construction manner, and so that the subsequent concrete pouring and formwork removal operations can be rapidly performed to accelerate the construction speed of the reinforced concrete structure, is a problem that is expected to be solved in the industry.

Detailed Description

For better understanding of the features, contents, advantages and effects achieved by the present invention, the present invention will be described in detail below with reference to the accompanying drawings in which the drawings are used for illustration and the accompanying specification, and the drawings are not intended to be read and limited to the accompanying drawings.

As described above, the present invention is intended to provide a building embedded member structure capable of improving the anchoring force between the building embedded member and the reinforced concrete structure, wherein the building embedded members are not completely embedded in the reinforced concrete structure, but partially exposed outside the reinforced concrete structure to be accessible, so as to enhance the anchoring force and improve the fixation stability and durability. The building embedded members include, but are not limited to, members that need to be embedded or fixed in a reinforced concrete structure when the reinforced concrete structure is formed, such as electrical junction boxes, elbow joints, floor joints, beam-through sleeves, beam-through sleeve seats, or hangers. An explanation will be given below of an exemplary structure in which the octagonal electrical junction box used in construction work as a construction embedded member proposed by the present invention is described.

Fig. 1 shows a building embedded component in the form of an electrical junction box according to a preferred embodiment of the invention. As shown in fig. 1, the electrical junction box 1 includes a top plate 11 and a peripheral side plate 12, the peripheral side plate 12 is connected to a peripheral edge 111 of the top plate 11 and extends downward from the peripheral edge 111 of the top plate 11 to define a hollow inner space 13 of the electrical junction box 1 together with the top plate 11, the peripheral side plate 12 is composed of a plurality of side plates 121 and has at least one electrical connection hole 14, and the electrical connection hole 14 has a blind cover 141 covering it. The blind cover 141 is used before the electrical connection hole 14 is used to avoid slurry leakage during the pouring operation. It should be noted that in the embodiment shown in fig. 1, the peripheral side plate 12 is composed of 8 side plates 121 to form an octagonal electrical junction box, but in other embodiments, the number of side plates is not limited to 8, and may be 4, 5, 6, etc. in different numbers (as needed) to form a polygonal electrical junction box. In addition, as shown in fig. 1, the lug 15 extends from a bottom edge of one or more of the side plates 121 of the surrounding side plate 12 toward a direction away from the central axis C of the internal space 13, and the lug 15 has at least one through hole 151 formed therein. The number of lugs 15 may be one or more, preferably at least two. In the embodiment shown in fig. 1, one lug 15 is shown extending outwardly from the bottom edge of the side plate 121 and another lug 15 is shown extending outwardly at the bottom edge of the side plate 121 opposite thereto. Depending on the actual requirements, the bottom edges of the other side plates of the electrical junction box 5 may each be provided with an outwardly extending lug 15. The purpose of the lugs 15 may be, for example and without limitation, to secure the electrical junction box 15 to an aluminum form during construction of a reinforced concrete structure.

The electrical junction box 1 may further have a structure of an inward lug (not shown in the drawings) extending from a bottom edge of one or more of the side plates 121 of the surrounding side plate 12 toward the direction of the central axis C of the internal space 13, and the inward-extending lug further has at least one through hole formed therein. These inwardly extending lugs are intended to be used for fastening other components, for example for locking the electrical junction box 1 to a mounting frame for mounting electrical equipment (for example lighting) or other lifting components.

The peripheral side plate 12 of the electrical junction box 1 has at least one recess 122. In the embodiment shown in fig. 1, a plurality of grooves 122 are formed on the surface of each side plate 121 constituting the peripheral side plate 12. The purpose of providing the grooves on the surface of the peripheral side plate of the electrical junction box 1 is to increase the total surface area of the peripheral side plate. Since the anchoring force between the building embedded member and the reinforced concrete is proportional to the contact area between the building embedded member and the reinforced concrete, in the electrical junction box 1 shown in fig. 1, the plurality of grooves 122 are disposed to increase the total contact surface area between the reinforced concrete structure and the surrounding side plates 12 of the electrical junction box 1, thereby improving the anchoring force of the electrical junction box 1 in the reinforced concrete structure.

Fig. 2 shows a building embedded member in the form of an electrical junction box according to another preferred embodiment of the present invention. As shown in fig. 2, the electrical junction box 1 'includes a top plate 11 "and a peripheral side plate 12', the peripheral side plate 12 'being connected at a distance D recessed from a periphery 111' of the top plate 11 'and extending downward from the top plate to define a hollow interior space 13' of the electrical junction box 1 'together with the top plate 11'. Similar to the embodiment shown in fig. 1, the peripheral side plate 12 'of the electrical junction box 1' of fig. 2 is made up of a plurality of side plates 121 'and has at least one electrical connection hole 14', which electrical connection hole 14 'is also covered by a corresponding blind cover 141'. In the embodiment shown in fig. 2, the peripheral side plate 12 'is formed by 8 side plates 121' to form an octagonal electrical junction box, but the number of the side plates is not limited to 8 in other embodiments, and may be 4, 5, 6, etc. (as required) to form a polygonal electrical junction box. The electrical junction box 1 'shown in fig. 2 has a lug 15' extending from a bottom edge of one or more of the side plates 121 'of the peripheral side plate 12' in a direction away from the central axis C 'of the internal space 13', and the lug 15 'has at least one through hole 151' formed therein. The number of lugs 15 may be one or more, preferably at least two. Depending on the actual requirements, the bottom edges of the other side plates of the electrical junction box 1 'may each be provided with an outwardly extending lug 15'. The electrical junction box 1' may further have a structure (not shown) of a lug extending from a bottom edge of one or more of the side plates 121' of the surrounding side plate 12' toward the central axis C ' in the inner space 13', and the lug extending inwardly has at least one through hole formed therein. The peripheral side plate 12' of the electrical junction box 1' has at least one recess 122 '. In the embodiment shown in fig. 2, a plurality of grooves 122 'are formed on the surface of each side plate 121' to increase the total surface area of the surrounding side plate 12 'and thus increase the total contact area of the reinforced concrete structure with the surrounding side plate of the electrical junction box 1'.

The electrical junction box 1' shown in fig. 2 has its peripheral side plate 12' located at a distance D from the periphery 111' of the top plate 11', so that the electrical junction box 1' shown in fig. 2 has an enlarged structural configuration of the top plate 11' compared to the electrical junction box 1 shown in fig. 1, which not only provides a larger contact surface area for the electrical junction box 1', but also fills the annular space formed around the peripheral side plate 12' below the top plate 11' at the distance D when the electrical junction box 1' is embedded and fixed in the reinforced concrete structure after the reinforced concrete structure is formed, whereby the electrical junction box 1' shown in fig. 2 can be more firmly embedded in the reinforced concrete structure. With this design, the electrical junction box 1 'cannot be detached from the reinforced concrete structure unless the tensile force applied to the electrical junction box 1' can be greater than the strength of the concrete or the surrounding concrete structure thereof is damaged by a tool intentionally.

Fig. 3 shows a building embedded member in the form of an electrical junction box according to yet another preferred embodiment of the present invention. As shown in fig. 3, the electrical junction box 1 "includes a top plate 1" and a peripheral side plate 12", the peripheral side plate 12 'is connected to a peripheral edge 111" of the top plate 11' and extends downward from the top plate 11 "to define a hollow inner space 13" of the electrical junction box 1 "together with the top plate 11". Similar to the embodiment shown in fig. 1, the peripheral side plate 12 "of the electrical junction box 1" of fig. 3 is made up of a plurality of side plates 121 "and has at least one electrical connection hole 14", the electrical connection hole 14 "being covered by a corresponding blind cover 141". In the embodiment shown in fig. 3, the peripheral side plate 12 "is likewise represented by 8 side plates 121" forming an octagonal electrical junction box. However, the number of the side plates is not limited to 8 in other embodiments, and may be different depending on the actual needs to form the polygonal electrical junction box. The electrical junction box 1 "shown in fig. 3 has a lug 15" extending from a bottom edge of one or more of the side plates 121 "of the peripheral side plate 12" toward a direction away from the central axis C "of the interior space 13", and the lug 15 "has at least one through hole 151" formed therein. The number of lugs 15 "may be one or more, preferably at least two. Depending on the actual requirements, the bottom edges of the other side plates of the electrical junction box 15 "may each be provided with an outwardly extending lug 15". The electrical junction box 1 "may also have a structure (not shown) of a lug extending from a bottom edge of one or more of the side plates 121" of the surrounding side plate 12 "toward the direction of the central axis C" in the inner space 13", and the lug extending inward further has at least one through hole formed therein.

The electrical junction box 1 "shown in fig. 3 is different from the electrical junction box 1 of fig. 1 in that a peripheral side plate 12" of the electrical junction box 1 "extends obliquely downward from a top plate 11" toward a central axis C "of an internal space, so that the electrical junction box 1" is formed into an inverted cone-shaped structure. The side plate 121 "of such an inverted cone-shaped electrical junction box 1" has a larger surface area than the side plate 121 of the electrical junction box 1' shown in fig. 1, thus providing a larger contact surface area with concrete and enhancing anchoring force. Furthermore, the inverted cone-shaped structure of the electrical junction box 1 "makes it to assume the form of an enlarged head, so that the form of the enlarged head of the electrical junction box 1" shown in fig. 3 enables the electrical junction box 1 "to be more firmly embedded in the reinforced concrete structure when the electrical junction box 1" is embedded and fixed in the reinforced concrete structure after the reinforced concrete structure is formed. With this design, the electrical junction box 1 "cannot be detached from the reinforced concrete structure unless the tensile force applied to the electrical junction box 1" can be greater than the strength of the concrete or the surrounding concrete structure thereof is damaged by a tool intentionally.

The peripheral side plate 12 "of the electrical junction box 1" shown in fig. 3 is inclined from the top plate 11 "toward the central axis C" of the internal space 13 "by a taper angle a such that the slope of the peripheral side plate 12" with respect to the top plate 11 "conforms to one selected from morse tapers No. 0 to No. 7. Of course, the present invention does not limit the taper of the electrical junction box 1 ″ to be one of morse tapers 0 to 7, and different tapers can be set according to actual requirements.

In other embodiments of the present invention, in order to further increase the contact surface area between the electrical junction box 1 ″ and the reinforced concrete, at least one groove (preferably, a plurality of grooves) may be further provided on the surrounding side plate 12 ″ of the electrical junction box 1 ″ in fig. 3 on the surrounding side plate 12 ″ of the electrical junction box 1 ″ to increase the total surface area of the surrounding side plate, thereby increasing the contact area between the reinforced concrete structure and the surrounding side plate of the electrical junction box 1 ″.

In other embodiments of the present invention, a convex portion may be provided on the surface of the surrounding side plate of the electrical junction box of fig. 1 to 3, or a recess and a convex portion may be provided in a staggered arrangement, so as to increase the total contact area of the reinforced concrete structure and the electrical junction box embedded in the reinforced concrete structure in different ways, thereby enhancing the anchoring force of the electrical junction box in the reinforced concrete structure.

Fig. 4a to 4d show schematic views of a process of coupling a plurality of pipe joints to an electrical junction box and sleeving with a pipe. The electrical junction box shown in fig. 4a is the electrical junction box 1 shown in fig. 1. Although fig. 4a shows four pipe joints 16, in practice, the number of pipe joints depends on the number of pipes to be connected to the electrical junction box 1, which are embedded in a reinforced concrete structure. Fig. 4a shows the electrical junction box 1 with the blind cap 141 of the electrical junction hole 14 intended for connecting tubing removed and the blind cap 141 of the unused electrical junction hole not removed. The pipe joint 16 has a structure including a nipple portion 161 and a flange portion 162 formed at one end of the nipple portion, and an outer diameter d1 of the nipple portion 161 is about the same as a diameter of the electrical connection hole 14 of the electrical junction box 1, whereby the nipple portion 161 can pass through the electrical connection hole 14. As shown in fig. 4b, when the pipe joint is assembled, the pipe joint 16 is fixed to the electrical junction box 1 by sticking the annular contour surface 163 of the flange portion 162 of the pipe joint 16 to the inner surface of the peripheral side plate 12 of the electrical junction box 1 from the inner space 13 of the electrical junction box 1 through the electrical connection hole 14 to the outside of the electrical junction box 1. Subsequently, as shown in fig. 4c, the inner diameter d2 of the pipe P destined to be connected to the electrical junction box 1 is substantially the same as the outer diameter d1 of the nipple portion 161 of the pipe joint 16, whereby the pipe P can be sleeved onto the corresponding pipe joint 16, eventually forming the assembly aspect of fig. 4d after assembly.

It should be noted that fig. 4a to 4d exemplify the electrical junction box 1 shown in fig. 1, but the application of the pipe joint is not limited solely to the electrical junction box 1 in fig. 1. The electrical junction boxes 1' and 1 ″ shown in fig. 2 and 3, as well as other types of electrical junction boxes, can also be applied with the pipe joint shown in fig. 4a to 4d and the assembly method thereof.

The following embodiments of the present invention provide a construction method for embedding a building embedded member in a reinforced concrete structure (or a precast reinforced concrete structure), particularly a method for embedding a building embedded member in reinforced concrete formed therein in a configuration using an aluminum form and placed with concrete. The building embedment member includes an electrical junction box as shown in fig. 1 to 4, an electrical junction box of other aspects, an elbow joint, a floor joint, a through beam sleeve or a hanger, and the like. The construction method disclosed in the embodiment is helpful for the subsequent arrangement operation of water and electricity pipelines, public pipelines or strong/weak electricity systems of buildings.

Fig. 5 and 6 show a construction method according to a preferred embodiment of the present invention. It should be noted that, for the sake of simplifying the drawings and facilitating understanding, fig. 5 and 6 do not show the whole aluminum formwork structure built at the site where the reinforced concrete structure is built, but only show the aluminum formwork at the predetermined arrangement of the building embedded members, and the octagonal electrical junction box shown in fig. 1 is taken as an exemplary member type of the building embedded members. As shown in fig. 5, in the building construction, an aluminum form 2, a plurality of fixing members 3, and a building embedding member 4 are provided, which includes two lugs 42 laterally extending from one end thereof. Each of the lugs 41 has two perforations 42. Referring to fig. 5, the construction worker first lays out the first surface 21 of the aluminum formwork 2 to define a predetermined position 22 for fixing the end surface of the building element 4 to the first surface 21 of the aluminum formwork 2. In other words, the predetermined position 22 defined on the first surface 21 of the aluminum form 2 conforms to the end profile of the bottom end of the building embedded member 4. Subsequently, the constructor drills holes at predetermined positions 22 on the first surface 21 of the aluminum formwork 2 to form a plurality of first holes 23. The first holes 23 are a plurality of through holes 42 respectively corresponding to the lugs 41 of the distal end of the building embedding member 4.

After that, the construction worker passes each of the plurality of through holes 42 of the building embedding member 4 with the plurality of fixing pieces 3 and inserts each of the corresponding first holes 23 of the aluminum formwork 2 to fix the building embedding member 4 to the predetermined position 22 of the first surface 21 of the aluminum formwork 2, forming the structure as shown in fig. 6.

Fig. 7a shows the structure of the plastic nail selected for use as a fastener according to the preferred embodiment of the present invention. The plastic pin 31 includes a head 311 and a shaft 312, the shaft 312 includes a plurality of flexible annular protrusions 313 protruding therefrom, and the maximum radial dimension of the flexible annular protrusions 313 is at least slightly larger than the diameter of the first hole 23 and the through hole 42. Fig. 7b shows a schematic view of the fixing of the building embedded member 4 to the aluminium formwork 2 using the plastic nails 3. When the plastic nail 31 is inserted through the through hole 42 of the building embedded member 4 and the first hole 23 of the aluminum form 2, the flexible annular protrusion 313 may deform to allow the plastic nail 31 to pass through the through hole 42 and the first hole 23, and complete the driving action into the first hole 23 when the head 311 of the plastic nail 31 is stopped by the surface of the lug 41 of the building embedded member 4 or the surface of the surrounding flange structure. In the process, the plurality of flexible annular protrusions 313 of the plastic nail 31 are deformed to be tightly combined with the inner surfaces of the plurality of first holes 23 of the aluminum formwork 2, and the plastic nail 31 is fastened in the first holes 23 of the aluminum formwork 2 and the through hole 42 of the building embedded member by the restoring force of the deformed flexible annular protrusions 313, so that the building embedded member 4 is fixed on the predetermined position of the aluminum formwork 1, thereby forming a building structure.

Fig. 8a shows the combination of expansion nails selected for use as fasteners in accordance with the preferred embodiment of the present invention. As shown in fig. 8a, the expansion nail 32 comprises an expansion tube 321 and a metal nail 321'. The expansion tube 321 is typically made of plastic and includes a head 322, a shaft 323, and a hollow second bore 324. The metal peg 321' also includes a head portion 322' and a shaft portion 323 '. The diameter of the shaft 323' of the metal spike 321' may be generally slightly larger than the inner diameter of the second bore 324 of the expansion tube 321, so that the shaft 22 of the metal spike 321' may radially expand the expansion tube 321 when inserted into the second bore 324 of the expansion tube 321. Fig. 8b shows an exemplary diagram of the building structure during construction, in which the building embedded member 4 is fixed to the aluminum formwork 2 by using the expansion nail combination. In operation, the expansion pipe 321 is first inserted or driven into the first hole 23 of the aluminum formwork 2 as a pre-cast fastener. Subsequently, the metal nails 321 'are inserted or nailed through the through holes 42 of the building embedding element 4 and into the second holes 324 of the expansion pipes 321 as embedding fasteners at the corresponding positions, whereby the expansion pipes 321 will be radially expanded by the metal nails 321' and the building embedding element 4 will thus be firmly fixed to the predetermined position 22 of the aluminum formwork 2. It should be noted that, in another embodiment as shown in fig. 8a, the rod 323 of the expansion pipe 321 as the embedded fastener comprises a plurality of flexible protrusions 325 on the rod 323 thereof, when the expansion pipe 321 is embedded in the first hole 23 of the aluminum form, and the metal nail 321' is inserted through the through hole 42 of the building embedded member 4 and driven into the second hole 324 of the expansion pipe 321 as the embedded fastener at the corresponding position, the expansion pipe 321 can be fastened in the first hole 23 of the aluminum form 2 by the restoring force after the flexible protrusions 325 are deformed, so that the building embedded member 4 will be firmly fixed at the predetermined position of the aluminum form 2 to form a building structure.

In another preferred embodiment of the present invention as shown in fig. 9, after the first surface 21 of the aluminum form 2 defines the predetermined position 22 corresponding to the end surface contour of the building embedding member 4, the construction worker directly applies the adhesive on the end surface contour of the end of the building embedding member 4, and/or the bottom surface of the lug 41 facing the aluminum form 2, and/or the bottom surface of the surrounding flange structure (not shown) facing the aluminum form 2, and directly fixes the building embedding member 4 to the predetermined position 22 of the first surface 21 of the aluminum form 2 by adhesion, thereby forming a building structure.

In yet another preferred embodiment as shown in fig. 10, the constructor defines a predetermined position 22 on the first surface 21 of the aluminium formwork 2, which corresponds to the end profile of the building embedding element 4. Subsequently, a module 5 is provided, which has an outer peripheral surface 51, and the building embedding element 4 has an inner peripheral surface 45 (see fig. 14a) delimiting the inner space 44, said outer peripheral surface 51 of the module 5 matching the inner peripheral surface 45 of the building embedding element 4, or at least matching a part of the inner peripheral surface 45 of the building embedding element 4, sufficiently to enable the building embedding element 4 to be snapped onto the module 5. With these structures, the worker can apply the adhesive on the end surface 52 of the module 5 facing the first surface 21 of the aluminum formwork 2 and adhesively fix the end surface 52 of the module 5 to the predetermined position 22 on the first surface 21 of the aluminum formwork 2. Subsequently, the construction worker can fix the building embedding member 4 to the predetermined position 22 of the first surface 21 of the aluminum formwork 2 by clamping the inner peripheral surface 45 of the building embedding member 4 on the outer peripheral surface 51 of the module 5, so as to form a building structure.

In yet another preferred embodiment of the present invention as shown in fig. 11, the constructor defines a predetermined position 22 on the first surface 21 of the aluminium formwork 2, which corresponds to the end profile of the building embedding element 4. Subsequently, two modules 5' are provided, each having a specific outer surface 51', while the building embedding element 4 has an inner peripheral surface 45 (see fig. 15a) defining an inner space 44, the specific outer surfaces 51' of each of the two modules 5 being matable to different parts of the inner peripheral surface 45 of the building embedding element 4, respectively. With these structures, the constructor can apply the adhesive on the end surface 52' of each of the two modules 5' facing the first surface 21 of the aluminum formwork 2 and adhesively fix the end surface 52' of each of the two modules 5 to the predetermined position 22 of the first surface 21 of the aluminum formwork 2 corresponding to the building embedded member 4. Subsequently, the constructor can clip the inner peripheral surface 45 of the building embedding member 4 to the specific outer surface 51 'of each of the two modules 5'. In other words, the building core 4 can be stuck on the two modules 5' adhered to the first surface 21 of the aluminum form 2 and then fixed to the first surface 21 of the aluminum form 2 at a predetermined position by matching the specific outer surfaces 51' of the two modules 5' with different portions of the inner peripheral surface 45 of the building core 4, respectively, to form a building structure. It should be noted that the two modules 5' may be of the same configuration or of different configurations, as long as the particular outer surface 51' of each of the two modules 5' is capable of mating with a different portion of the inner peripheral surface 45 of the building insert 4, respectively, to enable the building insert 4 to be sleeve-secured thereto. In other embodiments of the present invention, the number of modules is not particularly limited to two modules, and three or more modules may be applied. However, the smaller the number of modules, the more simplified the construction process, provided that it is sufficient to allow the building insert 4 to be clamped on the modules. In addition, the modules used in fig. 10 and 11 may be made of rubber or foam, which has the advantage of low manufacturing cost.

After the aluminum formwork nailing operation is completed and the building embedded member is fixed at a predetermined position of the aluminum formwork in the above-described manner, the constructor further puts concrete in a space formed by the aluminum formwork and other aluminum formworks to form a reinforced concrete structure. And after the pouring operation is finished, the building embedded member is embedded and fixed in the reinforced concrete structure. After the concrete is dried, the construction worker performs an operation of removing the aluminum formwork so that the reinforced concrete structure and the building embedded member embedded and fixed in the structure are separated from the first surface of the aluminum formwork.

Fig. 12a to 12c show the aluminium formwork removal process in the manner of fixing the building core 4 using the fixing members 3. As shown in fig. 12a, the aluminum formwork 2 has a completed reinforced concrete structure S thereon, and the building embedded member 4 is also embedded in the reinforced concrete structure S. Subsequently, as shown in fig. 12b, the constructor removes the aluminum formwork 2, and at this time, a portion of the fixing member 3 protrudes from the surface S1 of the reinforced concrete structure S. The protruding part of the fixing member 3 is, for example, a part of the shaft part 312 of the plastic nail shown in fig. 7a, or a part of the shaft parts 323 and 323 'of the expansion tube 321 and the metal nail 321' shown in fig. 8 a. The constructor can then directly cut off the parts of the fixing members 3 protruding from the surface S1 of the formed reinforced concrete structure S, so as to quickly finish the finishing operation after the building embedded members 4 are embedded into the reinforced concrete structure S.

Fig. 13a and 13b, fig. 14a and 14b, and fig. 15a and 15b respectively show the demolition of the aluminum formwork after the reinforced concrete structure is formed by using the construction method of fig. 9, 10, and 11. Fig. 13a shows the reinforced concrete structure S of fig. 9 after the casting operation is completed after the embedded members 4 are directly fixed to the aluminum formwork 2 by the adhesive. As shown in fig. 13a, the aluminum formwork 2 has a completed reinforced concrete structure S thereon, and the building embedded member 4 is also embedded in the reinforced concrete structure S. Subsequently, as shown in fig. 13b, the constructor directly removes the aluminum formwork 2, and at this time, since the building embedded member 4 is firmly embedded in the reinforced concrete structure S, the removal of the aluminum formwork 2 does not tear the building embedded member 4 off the reinforced concrete structure S together. When the constructor directly removes the aluminum form 2, the construction of embedding the building embedded member into the reinforced concrete structure is completed, as shown in fig. 13 b.

Fig. 14a shows the reinforced concrete structure S of fig. 10 after the module 5 is adhesively fixed to the aluminum formwork 2 by the adhesive, the building embedded member 4 is clamped on the module 5, and the casting operation is completed. As shown in fig. 14a, the aluminum formwork 2 has a completed reinforced concrete structure S thereon, and the building embedded member 4 is also embedded in the reinforced concrete structure S. Subsequently, as shown in fig. 14b, the construction worker directly removes the aluminum form 2, and the building embedded member 4 is firmly embedded in the reinforced concrete structure S, because the building embedded member 4 is clamped on the module 5, when removing the aluminum form 2, the module 5 adhered to the aluminum form 2 is removed together with the aluminum form 2, and the building embedded member 4 is not torn off from the reinforced concrete structure S. Therefore, when the constructor directly removes the aluminum form 2, the work of embedding the building embedded member 4 into the reinforced concrete structure is completed, as shown in fig. 14 b. In addition, since the module 5 is adhered to the aluminum formwork 2 only, the module 5 and the aluminum formwork 2 can be easily separated by a worker after removing the aluminum formwork, and thus both can be recycled.

Fig. 15a shows the reinforced concrete structure S of fig. 11 after the two modules 5 'are adhesively fixed to the aluminum formwork 2 by using an adhesive, and the building embedded member 4 is clamped to the modules 5' and the casting operation is completed. As shown in fig. 15a, the aluminum formwork 2 has a completed reinforced concrete structure S thereon, and the building embedded member 4 is also embedded in the reinforced concrete structure S. Subsequently, as shown in fig. 15b, the constructor directly removes the aluminum formwork 2, at which time the fixing member 4 is firmly fitted in the reinforced concrete structure S, and removes the aluminum formwork 2, the module 5 'adhered to the aluminum formwork 2 is removed together with the aluminum formwork 2 without the building embedded member 4 being torn off from the reinforced concrete structure 10, since the building embedded member 4 is caught and seated on the module 5' in a catching manner. Therefore, when the constructor directly removes the aluminum form 2, the construction of embedding the building embedded member 4 into the reinforced concrete S structure is completed, as shown in fig. 15 b. In addition, since the module 5 'is adhered to the aluminum formwork 2 only, the module 5' and the aluminum formwork 2 can be easily separated by a worker who removes the aluminum formwork, whereby both can be recycled

The construction embedded member 4 shown in fig. 5 to 15b is an octagonal electrical junction box shown in fig. 1 as an exemplary construction embedded member, but the construction embedded member in the embodiment of the construction method can be applied to the octagonal electrical junction box in fig. 1, and is not limited to the octagonal electrical junction box shown in fig. 2 to 3, or a conventional octagonal electrical junction box, other types of electrical junction boxes (e.g., a quadrangular electrical junction box), or a conventional elbow joint, a floor joint, a beam-through sleeve seat or a hanger used in construction work.
