Description
- The present invention relates to a floor through-passage molding apparatus and constricting module thereof, and especially to, a floor through-passage molding apparatus in which a constricting module is employed to reinforce the entire structure of the apparatus.
- Nowadays, in a large building construction such as a manufactory construction, it is essential to adopt a through-passage forming apparatus or a molding apparatus so as to reserve a space required for each through-passage in a concrete floor. After poured into a circumambiency of the through-passage forming apparatus or molding apparatus, the concrete is set to form each concrete floor and its through passages treated as vents, supplying-water pipes or cable passageways. Earlier through-passage forming apparatus or molding apparatus is a mere hollow standing sleeve. However, a bearing capacity of the current manufactory floor needs higher so that a thickness of the concrete floor is thickened and a length of the through passage is elongated. This revokes the through-passage forming apparatus or molding apparatus such as the standing sleeve heightened and its stressed region widened against the concrete. To avoid an impact from a huge amount of poured concrete from oppressing the through-passage forming apparatus or molding apparatus to deform, even from damaging formation of the through passage, several conventional through-passage forming apparatuses or molding apparatuses, e.g. a Japanese Utility Model Publication No. H5-32586, a Japanese Patent Publication No. H11-81663 and a Japanese Patent Publication No. 2000-145142, have provided various improved technical solutions each of which structurally and primarily has an upper cover, a lower cover, a hollow standing sleeve and a long rod-like retaining assembly. For conveniently understanding,
FIG. 1 illustrates an exemplar upon the Japanese Patent Publication No. 2000-145142 and is explained as following: a hollow standingsleeve 5 has an upper opening and a lower opening both communicated with a hollow space thereof, wherein thelower cover 2 and theupper cover 4 both are formed with an aperture or an inner-threaded hole on a central position thereof. In assembly, the long rod-like retaining assembly 3 could be accommodated within the hollow space of the standingsleeve 5. Theupper cover 4 is used to cover the upper opening of the standingsleeve 5 and thelower cover 2 is used to cover the lower opening of the standingsleeve 5. Then, by threads and/or an additional nut located on two ends of the long rod-like retaining assembly 3, the two opposite ends of long rod-like retaining assembly 3 are respectively up-and-down screwed to the upper andlower cover lower cover 2, theupper cover 4 and the standingsleeve 5 triple to be integrated, firmly. To restrict the through-passage forming apparatus or molding apparatus within a specific position on the concrete floor, the through-passage forming apparatus or molding apparatus is joined in vertical direction relative to a horizontal construction molding of the concrete floor by its lower cover or the end of the retaining assembly. However, under a factual construction, the concrete would principally impact the through-passage forming apparatus or molding apparatus along a horizontal direction relative to the apparatus when poured. If the through-passage forming apparatus or molding apparatus is infirmly fastened on the horizontal construction molding of the concrete floor, the impact of the being-poured concrete very readily slants the through-passage forming apparatus or molding apparatus, whereby the through passages may be deformed or damaged after the concrete floor is set-to-formed. - Additionally, the upper cover, the lower cover and the retaining assembly would be stripped and removed from said through-passage forming apparatus or molding apparatus after formation of the concrete floor, except for only the standing sleeve which is reserved within the through passage of the concrete floor so that a firm connection between the standing sleeve and the concrete floor could not be always ensured. For example, the concrete floor might compress the standing sleeve since stressed under the construction.
- Accordingly, it is essential to develop a through-passage molding apparatus capable of reinforcing its entire structure so as to resolve the aforementioned problem.
- To eliminate the drawbacks of the aforementioned prior art, a primary objective of the present invention is to provide a floor through-passage molding apparatus which reinforces the entire structure thereof by a constricting module, whereby during a process of forming a concrete floor through passage, a higher impact-resisting capacity is provided to prevent the floor through-passage molding apparatus from being deformed or slanted.
- Besides, a secondary objective of the present invention is to provide a floor through-passage molding apparatus and a constricting module thereof. After forming a concrete floor through passage, said constricting module is capable of reinforcing a firm connection between the floor through-passage molding apparatus and the concrete floor.

In this annular arrangement, by connection of the second connection terminal of each of the short curved bodies with the first connection terminal of its neighbor short curved body, said plurality of short curved bodies are cascaded one by one into an elongated curved body along an adjustable radian until the first connection terminal and the second connection terminal on the two ends of the elongated curved body approach with each other for further building up a connection therebetween. To connect the second connection terminal of each of the short curved bodies with the first connection terminal of its neighbor short curved body, a pair of corresponding fastener assembly is utilized to be jointed with the cavities of said first connection terminal and said second connection terminal. Said pair of fastener assembly includes a bolt and a nut. By way of the bolt passing through the cavity of each of the first connection terminal and second connection terminal to screw on the nut, the second connection terminal of each of the short curved bodies is connected with the first connection terminal of its neighbor short curved body. The elongated curved body in which said plurality of short curved bodies are cascaded, is a deformable elastomer with an adjustable radian and thereby capable of extending along the outer circumference surface of the sleeve wall until the first connection terminal and the second connection terminal on the two ends of the elongated curved body approach with each other. Finally, by jointing the corresponding fastener assembly to the cavities of first connection terminal and the second connection terminal on the two ends of the elongated curved body, said elongated curved body can radially supports the outer circumference surface of the sleeve wall.
- In another embodiment, said elongated curved body, the first connection terminal and the second connection terminal are made in integral, wherein said first connection terminal and the second connection terminal are radially connected to the two opposite ends of said elongated curved body. The constricting module according to the present invention can greatly reinforce the entire structure of the floor through-passage molding apparatus such as a forming sleeve and thereby provides a higher impact resistance during a process of forming the concrete floor through passage, and especially in a horizontal direction where the being-poured concrete impacts, and can prevent the floor through-passage molding apparatus from deforming or slanting.
- In another embodiment, at least one of the short curved bodies in said elongated curved body further has a third connection terminal for connecting to the steel bars of said floor construction. After the forming process of the concrete floor through passage, said constricting module can reinforce a firm connection between the floor through-passage molding apparatus and the concrete floor.

FIG. 2 a depicts a floor through-passage molding apparatus 10 according to a first preferred embodiment of the present invention adapted for a floor construction having steel bars, which primarily and structurally comprises: a formingsleeve 100 and a constrictingmodule 110. - Said forming
sleeve 100 can be made of various types of metallic or plastic material and embedded within the floor construction having the steel bars and the concrete structure. By pouring the concrete to a circumambiency of the formingsleeve 100, the concrete after set will forms through passages each which is treated as vents, supplying-water pipes or cable passageways. Said formingsleeve 100 has asleeve wall 102 outwardly forming anouter circumference surface 1020 and defined with ahollow channel 104, afirst opening 106 and asecond opening 108. Saidfirst opening 106 and saidsecond opening 108 are respectively located on two opposite ends of said formingsleeve 100 and communicated with each other via saidchannel 104. In this embodiment, theouter circumference surface 1020 of thesleeve wall 102 of said formingsleeve 100 is formed with a radian, e.g. 2π (rad). - By reference to
FIGS. 2 a, 3 a and 3 b, said constrictingmodule 110 includes four separable shortcurved bodies 120 and four pairs offastener assemblies 128, wherein said four separable shortcurved bodies 120 assembled in an annular arrangement alongouter circumference surface 1020 of saidsleeve wall 102, wherein the radian of each of the shortcurved bodies 120 is π/2 (Arc length/radius=π/2), and each of the shortcurved bodies 120 is integrally formed with afirst connection terminal 124 and asecond connection terminal 126. Saidfirst connection terminal 124 and saidsecond connection terminal 126, each of which is respectively defined with acavity curved body 120. Before assembled into the annular arrangement, thesecond connection terminal 126 of each π/2-radian shortcurved bodies 120 is firstly connected with thefirst connection terminal 124 of its neighbor π/2-radian shortcurved body 120 by cascade. This would constitute an elongatedcurved body 122 with a π radian. Next, by so on and so forth, the other two shortcurved bodies 120 each having π/2 radian are cascaded one by one until said four shortcurved bodies 120 are cascaded into an elongatedcurved body 122 having a 2π radian, as shown inFIG. 3 b so that thefirst connection terminal 124 and thesecond connection terminal 126 on two ends of said elongatedcurved body 122 having a 2π radian approach with each other for making further connection therebetween. By following the one-by-one cascades of said four shortcurved bodies 120 each with π/2 radian, the radian of the elongatedcurved body 122 is enlarged from π to 2π, as the result shown inFIG. 3 b, which makes the radian of said elongatedcurved body 122 becoming an adjustable-variance radian. - During a process of connecting the
second connection terminal 126 of each of the shortcurved bodies 120 with thefirst connection terminal 124 of its neighbor shortcurved body 120, at least corresponding one pair offastener assemblies 128 is utilized to be jointed with thecavities first connection terminal 124 and thesecond connection terminal 126 of each of the shortcurved bodies 120 for the oncoming connections. In this embodiment, said each pair offastener assembly 128 includes abolt 1282 and anut 1284. Thebolt 1282 is adapted to pass through thecavities second connection terminal 126 of one of the shortcurved bodies 120 and thefirst connection terminal 124 of its neighbor shortcurved body 120, and then being screwed on thenut 1284. However, for another application, the connection of thesecond connection terminal 126 of each of the shortcurved bodies 120 with thefirst connection terminal 124 of its neighbor shortcurved body 120 also can adopt the other approach such as a soldering process but is not limited to usage of afastener assembly 128. Saidfastener assembly 128 is not limited to thebolt 1282 and thenut 1284 either. Any one technology capable of retaining thesecond connection terminal 126 of each of the shortcurved bodies 120 to thefirst connection terminal 124 of its neighbor shortcurved body 120 also can be adopted. - In a factual assembly as shown in
FIG. 2 b, said four shortcurved bodies 120 can be cascaded one by one to constitute the elongatedcurved body 122, except that the last-rest shortcurved body 120 and its neighbor shortcurved body 120. Thesecond connection terminal 126 of the last-rest shortcurved body 120 and thefirst connection terminal 124 of its neighbor shortcurved body 120 are not connected with each other in a temporary manner. Thus, a gap is formed between thefirst connection terminal 124 and thesecond connection terminal 126 on the two ends of the elongatedcurved body 122 to allow the pass through of the formingsleeve 100. This will bring the convenience for the floor construction workers. This will lead the elongatedcurved body 122 to put around theouter circumference surface 1020 of thesleeve wall 102 of the formingsleeve 100. That is because each of the shortcurved bodies 120 is made of a deformable elastomer such as a metallic material. Therefore, the cascaded elongated curved body also will be a deformable elastomer to provide the floor construction workers with a convenience of enlarging the gap of the elongatedcurved body 122 so as to put around the formingsleeve 100. After the elongatedcurved body 122 is put around the formingsleeve 100, the radian of the elongatedcurved body 122 is larger than the radian of each of the shortcurved bodies 120 but may be identical to or smaller than the radian (e.g. 2π) of theouter circumference surface 1020 of thesleeve wall 102. This makes thefirst connection terminal 124 and thesecond connection terminal 126 on the two ends of the elongatedcurved body 122 approaching with each other. At this moment, the floor construction workers can utilize a screwed joint among thecavities 1242 1262 of the first andsecond connection terminals curved body 122 and the correspondingfastener assembly 128 to accomplish said elongatedcurved body 122. Thus, said elongatedcurved body 122 completely surrounds theouter circumference surface 1020 of thesleeve wall 102, finally and thereby provides radial supporting forces for supporting theouter circumference surface 1020 of thesleeve wall 102. By the radial supports of the constrictingmodule 110, the entire structure of the formingsleeve 100 can be greatly reinforced during the processing of forming the throughpassage 162 of theconcrete floor 160, especially in a horizontal direction where the being-poured concrete impacts, and therefore provide a higher impact-resistance capacity to prevent the formingsleeve 100 from deforming or slanting. After the concrete on the circumambiency of the formingsleeve 100 is set to form the throughpassages 162, the formingsleeve 100 and the constrictingmodule 110 are embedded together within theconcrete floor 160 without being stripped therefrom so as to increase a connective degree between the formingsleeve 100 and theconcrete floor 160. - In another embodiment as shown in
FIG. 2 b, said first orsecond connection terminal curved bodies 120 positioned on theouter circumference surface 1020 of the formingsleeve 100 can be disposed or formed with a third connection terminal such as a soldering spot (not shown) for connecting to the steel bars 164 in theconcrete floor 160 beside any one side of the formingsleeve 100. Thus, after the throughpassage 162 of theconcrete floor 160 is formed, by connection of the constrictingmodule 110 to the steel bars 164, the firm connectivity between the formingsleeve 100 of the floor through-passage molding apparatus 10 and theconcrete floor 160 can be more reinforced. - In another embodiment as shown in
FIG. 2 b, any one of the shortcurved bodies 120 on theouter circumference surface 1020 of the formingsleeve 100 can be disposed or formed with a fourth connection terminal (not shown) such as a soldering spot or an jointing spot. The soldering spot can connect to thesleeve wall 102 of said formingsleeve 100. The jointing spot is integrally formed with thesleeve wall 102 of the formingsleeve 100. Then the shortcurved body 120 having the fourth connection terminal is cascaded with the other shortcurved bodies 120 to constitute the elongatedcurved body 122. Thus, the elongatedcurved body 122 can surround theouter circumference surface 1020 of the formingsleeve 100 for convenience of the floor construction workers assembling. Simultaneously, this can make a tighter connectivity between the constrictingmodule 110 and the formingsleeve 100 of the floor through-passage molding apparatus 10. -
