現將僅為例子但非用以限制的具體實施例，並參照所附圖式就本創作之較佳結構內容說明如下： Now it is only an example but not a specific embodiment for limitation, and with reference to the accompanying drawings, the preferred structural content of the present creation is described as follows:

圖1至圖3顯示本創作一實施例的預埋螺絲10，該預埋螺絲10係用來安裝在一混凝土灌漿空間內且固定在一模板上，當混凝土凝固且將模板拆除後，該預埋螺絲10可提供例如管路、管架、燈具及設備等物件吊掛使用。該預埋螺絲10包含一基座12、安裝在基座12上的一螺帽14及複數釘子16。在本實施例中，該基座12由塑膠材料一體製成且包含一底板18、自該底板18之頂面20向上延伸的一套筒22、及設於該底板18之頂面20且位在套筒22外側的至少一釘柱24，該套筒22的內部具有一結合孔26。在本實施例中，該基座12包含二釘柱24，各釘柱24內具有一釘孔28用以提供一對應的釘子16穿過。 Figures 1 to 3 show a pre-embedded screw 10 according to an embodiment of the present invention. The pre-embedded screw 10 is used to be installed in a concrete grouting space and fixed on a formwork. After the concrete is solidified and the formwork is removed, the pre-embedded screw 10 is The buried screw 10 can be used for hanging objects such as pipelines, pipe racks, lamps and equipment. The embedded screw 10 includes a base 12 , a nut 14 and a plurality of nails 16 mounted on the base 12 . In this embodiment, the base 12 is integrally made of plastic material and includes a bottom plate 18 , a sleeve 22 extending upward from the top surface 20 of the bottom plate 18 , and a sleeve 22 disposed on the top surface 20 of the bottom plate 18 and located At least one nail 24 on the outside of the sleeve 22 has a coupling hole 26 in the inside of the sleeve 22 . In this embodiment, the base 12 includes two nail posts 24 , and each nail post 24 has a nail hole 28 for allowing a corresponding nail 16 to pass through.

該螺帽14由金屬材料一體製成且包含一內部具有螺孔30的筒體32以及結合於該筒體32上端的一蓋體34，該蓋體34上設有二穿孔36。該筒體32容納在該套筒22的結合孔26內，且該蓋體34的二穿孔36與該基座12的釘孔28對齊。在本實施例中，該筒體32的外徑與該結合孔26的孔徑約相等，使得該筒體32可緊密地容納在該結合孔26內結合。在可行的實施例中，該結合孔26的內壁可設有凸出的環狀肩部(未圖示)用以提供該筒體32的底端抵靠。 The nut 14 is integrally made of metal material and includes a cylinder 32 with a screw hole 30 therein and a cover 34 coupled to the upper end of the cylinder 32 . The cover 34 is provided with two through holes 36 . The cylinder 32 is accommodated in the coupling hole 26 of the sleeve 22 , and the two through holes 36 of the cover 34 are aligned with the nail holes 28 of the base 12 . In this embodiment, the outer diameter of the cylindrical body 32 is approximately equal to the diameter of the coupling hole 26 , so that the cylindrical body 32 can be tightly received and coupled in the coupling hole 26 . In a feasible embodiment, the inner wall of the coupling hole 26 may be provided with a protruding annular shoulder (not shown) for providing the bottom end of the cylindrical body 32 to abut against.

在本實施例中，該預埋螺絲10包含二釘子16，各釘子16包含一釘身38，該釘身38包含在該釘身38的軸向分隔的一尖錐狀下端40與一上端42。該釘身38的外徑略小於該穿孔36與該釘孔28的孔徑，使得該釘身38的尖錐狀下端40可穿過該蓋體34的穿孔36與該基座12的釘孔28且釘入模板44內(見圖4)。該預埋螺絲10的特點在於，該釘子16的上端42外徑不大於該穿孔36與該釘孔28的孔徑，使得該釘子16的上端42可***該蓋體34的穿孔36與該基座12的釘孔28內。在本實施例中，該釘子16的上端42外徑與該釘身38的外徑相等。 In this embodiment, the pre-embedded screw 10 includes two nails 16 , each of the nails 16 includes a nail body 38 , and the nail body 38 includes a tapered lower end 40 and an upper end 42 that are axially separated from the nail body 38 . . The outer diameter of the nail body 38 is slightly smaller than the diameters of the through hole 36 and the nail hole 28 , so that the tapered lower end 40 of the nail body 38 can pass through the through hole 36 of the cover 34 and the nail hole 28 of the base 12 And nailed into the template 44 (see Figure 4). The pre-embedded screw 10 is characterized in that the outer diameter of the upper end 42 of the nail 16 is not greater than the diameter of the through hole 36 and the hole 28, so that the upper end 42 of the nail 16 can be inserted into the through hole 36 of the cover 34 and the base 12 in the nail hole 28. In this embodiment, the outer diameter of the upper end 42 of the nail 16 is equal to the outer diameter of the nail body 38 .

本創作的預埋螺絲10在實施上，如圖4與圖5所示，利用工具46將該預埋螺絲10的釘子16的下端40打入模板44，使得該預埋螺絲10固定在模板44上。當混凝土結構(例如建築物樓板)48灌漿後，該預埋螺絲10會包覆在混凝土結構48內而與混凝土結構48結合成一體。當將該模板44拆除後，如圖6所示，該預埋螺絲10的螺孔30會裸露於混凝土結構48外，以提供例如管路、管架、燈具及設備等物件螺固。 In the implementation of the pre-embedded screw 10 of the present invention, as shown in FIG. 4 and FIG. 5 , the lower end 40 of the nail 16 of the pre-embedded screw 10 is driven into the template 44 by the tool 46 , so that the pre-embedded screw 10 is fixed on the template 44 superior. After the concrete structure (eg, building floor) 48 is grouted, the embedded screw 10 is wrapped in the concrete structure 48 and integrated with the concrete structure 48 . After the template 44 is removed, as shown in FIG. 6 , the screw holes 30 of the embedded screws 10 will be exposed outside the concrete structure 48 to provide screw fastening for objects such as pipes, pipe racks, lamps and equipment.

再者，本創作的預埋螺絲10在實施上，具有節省人工將釘子敲斷的效果，進而解決混凝土碎屑與粉末掉入施工者眼睛的問題。具體而論，當將該模板44拆除時，該釘子16的上端42可穿過該蓋體34的穿孔 36與該基座12的釘孔28，因而，預埋螺絲10的釘子16會隨著模板44一起脫離混凝土結構48，如圖6所示。據此，不再需要人力使用工具將露出於混凝土結構外的釘子敲斷，而可改善習用技術的缺失，進而達成本創作預期的實施效果。 Furthermore, the pre-embedded screw 10 of the present invention has the effect of saving manual breaking of nails in implementation, thereby solving the problem of concrete debris and powder falling into the eyes of the constructor. Specifically, when the template 44 is removed, the upper ends 42 of the nails 16 can pass through the perforations in the cover 34 36 and the nail holes 28 of the base 12, so that the nails 16 of the pre-embedded screws 10 will be released from the concrete structure 48 together with the formwork 44, as shown in FIG. 6 . Accordingly, manpower is no longer required to use tools to break the nails exposed outside the concrete structure, and the lack of conventional techniques can be improved, thereby achieving the desired implementation effect of this creation.

在前述說明書中，本創作僅是就特定實施例做描述，而依本創作的特徵仍可有多種變化或修改。是以，對於熟悉此項技藝人士可作之明顯替換與修改，將併入於本創作所主張的專利範圍之內。 In the foregoing specification, the present invention is only described with respect to a specific embodiment, and various changes or modifications are still possible according to the features of the present invention. Therefore, obvious substitutions and modifications that can be made by those skilled in the art will be incorporated into the scope of the patent claimed in this creation.
