Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

The first embodiment is as follows:

referring to fig. 1 to 8, a formwork fixture for building construction includes a first fixing frame 1 and a second fixing frame 2 which are oppositely disposed, the first fixing frame 1 and the second fixing frame 2 are both U-shaped rods, and the ends of the two side rods of the first fixing frame 1 and the second fixing frame 2 are hollow, in this embodiment, the first fixing frame 1 and the second fixing frame 2 are both formed by welding three sections of square steel pipes end to end, so that the overall weight of the fixture can be reduced.

The two side rod ends of the first fixed frame 1 are internally and respectively connected with a first connecting rod 3 in an inserting manner, the two side rod ends of the second fixed frame 2 are internally and respectively connected with a second connecting rod 4 in an inserting manner, the end part of the first connecting rod 3 can be adjusted and positioned in the position of the first fixed frame 1, and the end part of the second connecting rod 4 can be adjusted and positioned in the position of the second fixed frame 2. Specifically, as shown in fig. 6, the first connecting rod 3 has a two-section structure, and the cross-sectional profile of the left section thereof matches the profile of the inner cross-section of the rod ends of the two sides of the first fixing frame 1, and the length thereof also matches the length of the side rod of the first fixing frame 1, so that the left section of the first connecting rod 3 can be inserted into the first connecting rod 3 (as shown in fig. 5). A plurality of (5 as shown in fig. 6) positioning pin holes 301 distributed at equal intervals are formed on the top surface of one end (left side section) of the first connecting rod 3 inserted into the first fixing frame 1, and pins 10 matched with the positioning pin holes 301 are movably inserted into the end parts of the side bars at two sides of the first fixing frame 1. After extracting bolt 10 from first fixed frame 1, accessible pull head rod 3 realizes the position quick adjustment of head rod 3 in first fixed frame 1, through the cooperation of bolt 10 with different location pinhole 301, realizes the position fixation of head rod 3 on first fixed frame 1 after the adjustment position. Obviously, a plurality of plug pin insertion ports arranged at equal intervals or at unequal intervals can be formed on the side lever of the first fixing frame 1, and the plug pin 10 is inserted into the position of the alignment fit through the alignment fit of the positioning pin hole 301 and the plug pin insertion ports, so that various positioning positions can be adjusted.

The right side section cross section profile of the first connecting rod 3 is matched with the side rod outer interface profile of the first fixing frame 1, so that after the first connecting rod 3 is completely inserted into the side rod of the first fixing frame 1, the end surface of the right side section of the first connecting rod just leans against the end surface of the side rod. At this time, the pin insertion port located at the outermost side is just aligned with the positioning pin hole 301 located at the innermost side, and after the pin 10 is inserted into the positioning pin hole 301 located at the innermost side, the first connecting rod 3 is fixedly connected to the first fixing frame 1, and the total length of the side edges of the first connecting rod 3 and the first fixing frame 1 is the minimum.

In the embodiment, the second fixed frame 2 and the first fixed frame 1 are symmetrically arranged, and the structure of the second fixed frame 2 is completely the same as that of the first fixed frame 1 because the first fixed frame 1 is also of a symmetrical structure; the structure of the second connecting rod 4 is symmetrical to that of the first connecting rod 3 and is completely the same as that of the first connecting rod 3; therefore, the coupling and position adjustment between the second connecting rod 4 and the second fixed frame 2 are the same as those between the first connecting rod 3 and the first fixed frame 1.

An adjusting rod 5 is in threaded connection between the first connecting rod 3 and the second connecting rod 4 which are positioned on the same side, the spiral directions of the thread sections at the two ends of the adjusting rod 5 are opposite, and the thread pitches are equal.

The second connecting rod 4 is in threaded connection with the right-hand threaded section of the adjusting rod 5. Because the screw directions of the screw thread sections at the two ends of the adjusting rod 5 are opposite, when a wrench and other tools act on the adjusting nut, the adjusting rod 5 can be rotated forward or reversely to enable the first connecting rod 3 and the second connecting rod 4 to be close to or far away from each other synchronously under the effect of screw transmission, so that the relative position between the first connecting frame 1 and the second connecting frame 2 is adjusted, namely the whole width of the template clamp is adjusted.

Preferably, the thread segments on both sides of the adjusting nut are not equal in length, and in this embodiment, the length L of the thread segment on the left side of the adjusting nut is greater than the length L of the thread segment on the right side thereof, as shown in fig. 5. So, in the in-process of template anchor clamps disassembling, when rotating the regulation pole 5 in succession, second connecting rod 4 can separate with adjusting pole 5 earlier, and the left end still has a segment and keeps the threaded connection state with head rod 3, under the state of accomplishing the fixed frame 2 of second and the separation of first fixed frame 1, adjust pole 5 and keep on head rod 3, avoid adjusting pole 5 to drop and the loss appears easily, also avoid next time need carry out threaded connection with adjusting pole 5 and head rod 3 once more when using this template anchor clamps.
