However, the buckle assembly of the existing device has a low fixing and limiting effect on the steel truss. When the top of the steel truss is subjected to pressure from the upper building structure due to gravity attraction, the steel truss and the buckle will be disconnected, causing damage to the steel truss floor deck and unexpected building problems.

[0021] The steel bar truss assembly includes a web member 51, and the number of the web members 51 is two. The web members 51 are placed inside the working groove 4. A steel bar lower chord 52 is welded to the bottom of the outer surface of the web member 51, and the number of the steel bar lower chord 52 is two. A steel bar upper chord 53 is welded to the top of the inner surface of the web member 51.

[0022] The fixing assembly 6 includes a limiting vertical slot 61 and a limiting oblique slot 62. The number of the limiting vertical slots 61 is two, and the two limiting vertical slots 61 are respectively opened at the front side and the rear side inside the working slot 4; the number of the limiting oblique slots 62 is two, and the two limiting oblique slots 62 are respectively opened at the front side and the rear side inside the working slot 4, and the two limiting oblique slots 62 are respectively located on the outside of the two limiting vertical slots 61; a fixing rod 63 is placed on the top of the lower chord 52 of the steel bar, and a limiting vertical rod 64 is welded on the inner side of the surface of the fixing rod 63. The number of the limiting vertical rods 64 is three, and the bottom of the limiting vertical rod 64 is movably connected to the inside of the limiting vertical slot 61, and a limiting oblique rod 65 is welded on the outer side of the surface of the fixing rod 63. The number of the limiting oblique rods 65 is three, and the bottom of the limiting oblique rod 65 is movably connected to the inside of the limiting oblique slot 62. By setting the fixing component 6, the steel truss can be fixed and limited to avoid the situation in which the top of the steel truss is subjected to the pressure generated by the gravity attraction of the building structure above during use, which will cause the steel truss to be disconnected from the buckle and cause damage to the steel truss floor deck.
[0023] In specific implementation, there are six positioning holes 2, three positioning holes 2 on the front side and three positioning holes 2 on the rear side, and the three positioning holes 2 on each side are all at the same horizontal line left and right; a fixing block 3 is provided on each positioning hole 2. By providing six positioning holes 2, multiple steel bar trusses can be placed in the working groove 4 at the same horizontal line left and right at the same time, avoiding the situation that the fixing blocks 3 are not at the same horizontal line left and right during the concrete pouring process, resulting in the need for manual placement when using after pouring.
[0024] In specific implementation, the front and rear sides of the right bottom of the fixed block 3 are provided with horizontal holes 7, which penetrate to the front and rear sides of the left bottom of the fixed block 3, and the horizontal holes 7 on the same horizontal line on the left and right are slidably connected with cross bars 8; the three fixed blocks 3 on each side are connected together by two cross bars 8 on the front and rear sides.

[0026] In specific implementation, the interior of the positioning hole 2 is movably connected with a bolt 11, and the top of the bolt 11 is threadedly connected to the bottom of the fixing block 3. Through the arrangement of the bolt 11, the fixing block 3 can be conveniently connected to the top of the bottom plate 1, avoiding the situation that the bottom plate 1 cannot be detached after concrete pouring, so that the bottom plate 1 can be reused.
[0027] The working principle and use process of the utility model are as follows:
[0028] When in use, the user first places the fixing block 3 on the top of the positioning hole 2 opened on the top of the bottom plate 1, and then uses the bolt 11 to thread the fixing block 3 and the bottom plate 1, and uses the cross bar 8 to connect the horizontal holes 7 of the fixing blocks 3 that are at the same horizontal limit on the left and right in series, and respectively inserts the two ends of the fixing cross frame 10 into the fixing holes 9 of the two adjacent fixing blocks 3, so that the two adjacent fixing blocks 3 are at the same horizontal position on the left and right, and places the web member 51 inside the working groove 4, welds the lower chord 52 of the steel bar to the bottom of the outer surface of the web member 51, and welds the upper chord 53 of the steel bar to the top of the inner surface of the web member 51, and the installation of the steel truss assembly 5 is completed. , place the limiting vertical rod 64 inside the limiting vertical groove 61, and then place the limiting oblique rod 65 inside the limiting oblique groove 62, and use the building hammer to knock the fixing rod 63 downward, and the fixing rod 63 drives the limiting vertical rod 64 and the limiting oblique rod 65 to move toward the bottom of the limiting vertical groove 61 and the limiting oblique groove 62 respectively. When the bottom of the surface of the fixing rod 63 contacts the top of the surface of the lower chord 52 of the steel bar, the bottom of the surface of the fixing rod 63 is welded to the top of the surface of the lower chord 52 of the steel bar, and subsequent concrete pouring can be carried out. After the concrete pouring is completed, the fixing block 3 and the bottom plate 1 are removed by the bolts 11, thereby achieving an efficient fixing effect.
[0029] To sum up, the clip-on auxiliary device for fixing steel trusses, through the base plate 1, positioning holes 2, fixing blocks 3, working grooves 4, steel truss components 5, web members 61, steel lower chords 62, steel upper chords 63, fixing components 7, limiting vertical grooves 71, limiting oblique grooves 72, fixing rods 73, limiting vertical rods 74, limiting oblique rods 75, horizontal holes 8, cross bars 9, fixing holes 10, fixing cross frames 11, and bolts 12, solves the problem that the fixing and limiting effects of the clip-on components of the existing devices on the steel trusses are relatively low. When the top of the steel truss is subjected to the pressure generated by the gravity attraction of the building structure above, the steel truss will be disconnected from the clip, resulting in damage to the steel truss floor deck and construction accidents.
