Example 1

As shown in fig. 1 to 4, a detachable truss support includes: truss support 3, truss support 3 is whole to be the strip, and the middle part is equipped with the structure that is used for connecting bolt, and connecting bolt's structure is for running through truss support 3 and being equipped with the structure of through-hole. Both sides are equipped with outside arch 302, and arch 302 card is in one side of the lower string 101 of truss 1 in the horizontal direction, and the one side plays supporting role to lower string 101 and keeps truss 1 and bottom plate 4's relative position, and on the other hand restricts truss support 3 and lower string 101 horizontal direction's relative position, avoids taking place relative displacement when concrete placement, keeps the relatively stable of structure.

The side of the truss support opposite to the protrusion 302 is provided with a first groove 303 and a second groove 304 in the radial and axial directions of the truss support 3, respectively. After the concrete is poured, the first groove 303 can enable the concrete to wrap the truss support 3 from the lower part, and the truss support 3 is prevented from falling off from the poured concrete. The second groove 304 reduces the contact area with the bottom plate 4, and simultaneously, the arc-shaped structure is used for ensuring the structural elasticity and providing pre-tightening force for the bolt. The bolt is guaranteed not to loosen after being fixed.

Example 2

As shown in fig. 5 to 7, in this embodiment, a floor deck bottom structure includes a truss 1 and a bottom plate 4, and is characterized in that: still include truss support 3, truss support 3 sets up between truss 1 and bottom plate 4, truss 1 middle part is equipped with butterfly card 2, is equipped with a pair of circular arc breach 201 on the butterfly card 2. Truss 1, butterfly card 2, truss support 3 and bottom plate 4 are through a set of bolt fixed connection, the bolt passes through-hole and the connecting hole on the butterfly card 2 on the truss support 3, make truss support 3 and the fixed centre gripping of butterfly card 2 on lower chord 101, the bolt concatenates truss support 3, butterfly card 2 and bottom plate 4 simultaneously, the relative displacement of truss 1 and bottom plate 4 has been restricted in vertical direction, the displacement on the lower chord 101 horizontal direction has been restricted to arch 302 on the truss support 3.

4 below of bottom plate are equipped with strengthening rib 5, strengthening rib 5 is rectangular tubulose, is equipped with the opening on the strengthening rib 5, truss 1, butterfly card 2, truss support 3, bottom plate 4 and strengthening rib 5 are through a set of bolt fixed connection.

The reinforcing ribs 5 prevent the bottom plate 4 from being bent after the cement is poured. Simultaneously, bottom plate 4 is the master and slave material mostly, and strengthening rib 5 has increased the area of contact of bolt end and bottom plate 4, prevents to take place the bolt and pull from bottom plate 4 under the effect of bolt pretightning force and cement gravity and wears, avoids bolt and 4 locking connection's of bottom plate destruction.

The reinforcing rib 5 is internally provided with a sliding block 6, and the truss 1, the butterfly clamp 2, the truss support 3, the bottom plate 4, the reinforcing rib 5 and the sliding block 6 are fixedly connected through a group of bolts. The slider 6 can slide in the strengthening rib 5, provides more nimble hookup location, has avoided corresponding at the loaded down with trivial details of 5 screw holes of strengthening rib. When the reinforcing ribs 5 are processed, most of the installation conditions can be met only by processing the strip-shaped connecting holes 501.

The edge of the opening of the reinforcing rib 5 is curled inwards, and the sliding block 6 is clamped in the reinforcing rib 5. With this structure, the required slide block 6 can be put into the reinforcing bar 5 at one time when in use, and the slide block 6 is not required to be held by one hand when in installation.

Example 3

As shown in fig. 5, 8 and 9, in the present embodiment, the structure of the connecting bolt of the truss support 3 is a tubular body 301, and the through hole inside the tubular body 301 is a staggered structure. In the present embodiment, the bolt is composed of a first bolt 701 and a second bolt 702, and the first bolt 701 is an internally threaded bolt. As shown in FIG. 5, in the use process, the end of the first bolt 701 props against the staggered platform of the tubular body 301, and applies pressure to the truss support 3 at the two ends and the middle part together with the lower string 101, so as to ensure that the stress on the upper surface of the truss support 3 is uniform. Meanwhile, the first bolt 701 simultaneously applies force to the butterfly card 2 and the truss support 3, so that the pulling force of the first bolt 701 and the pulling force of the second bolt 702 can be distributed on structures of different layers, and the locking force of the mechanism is more balanced.

Simultaneously, after cement pouring finishes, tear bottom plate 4 open, hang nail and equipment fixing's connection basis when the internal thread of first bolt 701 can regard as later stage fitment, avoid later stage fitment to punch and install the inflation screw on the cement roof.
