Description

鎖固件lock

本發明是有關於一種鎖固件，特別是指一種用於鎖固建築模板的鎖固件。 The present invention relates to a locking piece, in particular to a locking piece for locking building templates.

如臺灣專利公告號TW I716319所示，一種現有的建築模板組，包括四片模板，及一體積小於該等模板的組合角木，每一模板具有一封膜面、一相反於該封膜面的組裝面、二分別設置於該組裝面上下兩側的連接柱，每一連接柱具有複數穿孔，該組合角木則具有複數組合孔。 As shown in Taiwan Patent Publication No. TW I716319, an existing building formwork set includes four formworks, and a combined angle wood with a volume smaller than the formworks. Each formwork has a sealing surface, an assembly surface opposite to the sealing surface, and two connecting columns respectively arranged on the upper and lower sides of the assembly surface. Each connecting column has a plurality of perforations, and the combined angle wood has a plurality of combination holes.

因此，透過將該等模板對齊堆疊，並將該組合角木對稱置於該等連接柱的相疊處，並由複數鎖固件穿設該等組合孔與該等穿孔，以固定該等模板與該組合角木，組合形成該建築模板組。 Therefore, by aligning and stacking the formworks, placing the composite corner timbers symmetrically at the overlapped positions of the connecting columns, and passing through the combination holes and the perforations by a plurality of locking pieces to fix the templates and the composite corner timbers, the building formwork group is assembled.

然而，藉由該等鎖固件固定該等模板，僅能依靠該組合角木協助該等模板定位，組裝完成後，該等模板的該等封膜面便容易產生不平整的情況，顯見現有技術仍有待改良的空間。 However, fixing the formworks by the fasteners can only rely on the combination angle wood to assist the positioning of the formworks. After the assembly is completed, the sealing surfaces of the formworks are prone to unevenness. It is obvious that there is still room for improvement in the prior art.

因此，本發明的目的，即在提供一種能解決上述問題的鎖固件。 Therefore, the purpose of the present invention is to provide a lock that can solve the above problems.

於是，本發明鎖固件，適用於組裝二建築模板，每一建築模板包括一板體，及一設置於該板體的其中一面的框架，每一框架界定出一定位孔，及一具有一內螺紋段的鎖固孔，該鎖固件包含一界定出一轉動軸線的肩部、一形成於該肩部的其中一端的受驅部、一連接該肩部的另一端並呈錐狀的定位部，及一連接該定位部的螺紋部。該定位部包括一連接該肩部的第一錐段及一連接該第一錐段的第二錐段，該第一錐段與該第二錐段共同沿該轉動軸線朝遠離該肩部的方向漸縮，且該第一錐段與該第二錐段的截面皆小於該肩部的截面，該第一錐段用於插入該等建築模板的其中一者的定位孔以限制該轉動軸線的偏移，而使該第二錐段顯露於該框架，該螺紋部連接該第二錐段且用於與該第二錐段共同插入該等建築模板的另一者的鎖固孔，以使該螺紋部螺鎖入該內螺紋段，直到該肩部靠抵該等建築模板的其中一者的該框架。 Therefore, the locking piece of the present invention is suitable for assembling two building formworks. Each building formwork includes a plate body and a frame disposed on one side of the plate body. Each frame defines a positioning hole and a locking hole with an internal thread section. The locking piece includes a shoulder defining a rotation axis, a driven portion formed at one end of the shoulder, a tapered positioning portion connected to the other end of the shoulder, and a threaded portion connected to the positioning portion. The positioning portion includes a first cone section connected to the shoulder and a second cone section connected to the first cone section. The first cone section and the second cone section are tapered away from the shoulder along the rotation axis, and the cross sections of the first cone section and the second cone section are both smaller than the cross section of the shoulder. inserting into the locking hole of the other of the building formworks, so that the threaded portion is screwed into the internal threaded segment until the shoulder abuts against the frame of one of the building formworks.

本發明的功效在於：藉由該定位部配合插入相對應的該定位孔與該鎖固孔，以使該等框架組裝時，限制該轉動軸線的偏移而保持穩定，而該等建築模板組裝完成後，連帶保持該等板體相反於該框架的另一面的平整度。 The effect of the present invention is that: the positioning part is inserted into the corresponding positioning hole and the locking hole, so that when the frames are assembled, the deviation of the rotation axis is limited and kept stable, and after the building templates are assembled, the flatness of the other side of the boards opposite to the frame is maintained.

The cone section 132 is integrally formed, and the taper of the first cone section 131 and the second cone section 132 is 1:8, and the shoulder portion 11 and the positioning portion 13 are integrally formed.

該螺紋部14連接於該第二錐段132，並具有一個形成有外螺紋141的外周面142，此為本領域的通常知識，且非本案的特徵所在，在此不予贅述。 The threaded portion 14 is connected to the second tapered section 132 and has an outer peripheral surface 142 formed with an external thread 141 , which is common knowledge in the art and is not a feature of this application, so it will not be repeated here.

參閱圖4與圖5，該第一實施例適用於組裝二建築模板2，更精確地說，該鎖固件1以該轉動軸線L1為軸轉動以鎖固該等建築模板2，每一建築模板2包括一板體21，及一設置於該板體21的其中一面的框架22，每一板體21上設有一可供提取而移動的吊環構件3，每一框架22界定出一定位孔221及一鎖固孔222，該定位孔221具有一對應該肩部11的大孔徑段223，及一對應該第一錐段131的第一錐形孔段224，該鎖固孔222具有一對應該外螺紋141的內螺紋段225，及一對應該第二錐段132的第二錐形孔段226，更精確地說，該鎖固孔222是由該內螺紋段225與該第二錐形孔段226共同界定而成。 Referring to Fig. 4 and Fig. 5, the first embodiment is suitable for assembling two building templates 2. More precisely, the locking member 1 rotates around the rotation axis L1 to lock the building templates 2. Each building template 2 includes a board body 21 and a frame 22 arranged on one side of the board body 21. Each board body 21 is provided with a lifting ring member 3 that can be extracted and moved. Each frame 22 defines a positioning hole 221 and a locking hole 222. The positioning hole 221 has a corresponding The large aperture section 223 of the shoulder 11 corresponds to the first tapered hole section 224 corresponding to the first tapered section 131 . The locking hole 222 has a pair of internal thread section 225 corresponding to the external thread 141 and a pair of second tapered hole section 226 corresponding to the second tapered section 132 . More precisely, the locking hole 222 is defined by the internal thread section 225 and the second tapered hole section 226 .

藉由多個該第一實施例(鎖固件1)裝配該等建築模板2，每一第一實施例的該第一錐段131用於插入該等建築模板2的其中一者的定位孔221以限制該轉動軸線L1的偏移，而使該第二錐段132顯露於該框架22，該螺紋部14用於與該第二錐段132共同插入該等建築模板2的另一者的鎖固孔222，以使該螺紋部14螺鎖入該內螺紋段225，直到該肩部11靠抵該等建築模板2的其中一者的該框架22。 The building templates 2 are assembled by a plurality of the first embodiments (locking pieces 1), the first tapered section 131 of each first embodiment is used to insert into the positioning hole 221 of one of the building templates 2 to limit the deviation of the rotation axis L1, so that the second tapered section 132 is exposed on the frame 22, and the threaded part 14 is used to be inserted together with the second tapered section 132 into the locking hole 222 of the other of the building templates 2, so that the threaded part 14 is screwed into the internal threaded section 2 25 until the shoulder 11 abuts against the frame 22 of one of the building formworks 2 .

欲組裝該等建築模板2時，藉由將每一第一實施例的該第一錐段131與該第二錐段132分別插入該等建築模板2的其中一者的定位孔221與該等建築模板2的另一者的鎖固孔222，以連接並組 裝該等建築模板2。 When the building templates 2 are to be assembled, the first cone section 131 and the second cone section 132 of each first embodiment are respectively inserted into the positioning hole 221 of one of the building templates 2 and the locking hole 222 of the other of the building templates 2 to connect and assemble Install the building formwork 2.

接著以其中一個第一實施例為例進行說明，該第一實施例與該等建築模板2組裝完成後，該等框架22共同由該第一錐段131與該第二錐段132穿設，搭配該定位孔221限制該轉動軸線L1的偏移，因而使該等框架22分別固定的該等建築模板2的板體21的其中一面彼此保持平整，故能使該等板體21相反於該框架22的另一面(即封膜面)保持平整，方便後續施作。 Then take one of the first embodiments as an example. After the first embodiment is assembled with the building templates 2, the frames 22 are jointly pierced by the first cone section 131 and the second cone section 132, and the positioning hole 221 is used to limit the deviation of the rotation axis L1, so that the one side of the boards 21 of the building templates 2 fixed by the frames 22 are kept flat with each other, so that the other side of the boards 21 opposite to the frame 22 (i.e. the sealing film surface) can be kept flat. It is convenient for follow-up operation.

此外，參閱圖6，本發明鎖固件1的一第二實施例，並未包含該連桿部10，而由該受驅部12包括一凸柱124，該凸柱124為多角柱，且該受驅部12與該肩部11為一體成型，如此即可省略該固定螺絲123，藉由配合另一手工具(如扳手，圖未示)套置或夾置該凸柱124而連帶轉動。 In addition, referring to FIG. 6, a second embodiment of the locking member 1 of the present invention does not include the connecting rod portion 10, but the driven portion 12 includes a protruding post 124. The protruding post 124 is a polygonal post, and the driven part 12 and the shoulder 11 are integrally formed, so that the fixing screw 123 can be omitted, and the protruding post 124 can be rotated jointly by cooperating with another hand tool (such as a wrench, not shown in the figure) to nest or sandwich the protruding post 124.

綜上所述，本發明鎖固件1藉由該定位部13配合插入相對應的該定位孔221與該鎖固孔222，以使該等框架22組裝時，限制該轉動軸線L1的偏移而保持穩定，而該等建築模板2組裝完成後，連帶保持該等板體21相反於該框架22的另一面的平整度，故確實能達成本發明的目的。 In summary, the locking member 1 of the present invention is inserted into the corresponding positioning hole 221 and the locking hole 222 through the positioning portion 13, so that when the frames 22 are assembled, the deviation of the rotation axis L1 is limited and kept stable, and after the building templates 2 are assembled, the flatness of the other side of the boards 21 opposite to the frame 22 is maintained, so the purpose of the present invention can indeed be achieved.
