[0039] It is worth mentioning that the inside of the frame body 701 is inserted with a horizontal keel 10, and the horizontal keel 10 is attached to the vertical keel 2. The horizontal keel 10 and the vertical keel 2 are the keels inside the steel drill floor body 1, which are used to increase the strength.
[0040] It is worth noting that, please refer to Figure 3 and Figure 6 The bottom of the horizontal keel 10 is provided with a bottom fixing part 11, which comprises a fixing seat 1101 attached to the horizontal keel 10. A plurality of fixing shafts 1102 are fixedly arranged on the top of the fixing seat 1101. A taper head 1103 is fixedly arranged on the top of the fixing shaft 1102. An annular inclined surface 11030 is arranged on the top surface of the taper head 1103. The bottom fixing part 11 is used to fix one of the vertical keel 2 and the horizontal keel 10. Preferably, the top of the fixing seat 1101 is provided with a fixing groove for the horizontal keel 10.
[0041] It is worth mentioning that the top of the vertical keel 2 is provided with a top fixing part 12, which comprises a fixing block 1201 attached to the vertical keel 2.

Thus, the bottom fixing part 11 and the top fixing part 12 further limit and fix the horizontal keel 10 and the vertical keel 2 arranged longitudinally and transversely by clamping.
[0042] Further, as Figure 6As shown, the inner part of the fixed block 1201 is fixedly provided with a positioning shaft 1202, the outer side of the positioning shaft 1202 is fixedly provided with a limiting shaft 1203, the outer side of the limiting shaft 1203 is sleeved with a spring 1204, and the limiting shaft 1203 is used for guiding and reinforcing the spring 1204 to prevent it from being stuck when being stretched and retracted.
[0043] It is worth emphasizing that the outer side of the limiting shaft 1203 is slidably provided with a sliding shaft 1205, and the spring 1204 is fixedly connected with the sliding shaft 1205, so that the spring 1204 is located between the positioning shaft 1202 and the sliding shaft 1205. The outer side of the sliding shaft 1205 is fixedly provided with an arc-shaped clamping block 1206, and the arc-shaped clamping block 1206 is clamped with the tapered head 1103. The bottom inner side of the arc-shaped clamping block 1206 is provided with an arc-shaped matching inclined surface 12060, and the arc-shaped matching inclined surface 12060 is slidably matched with the annular inclined surface 11030. When the tapered head 1103 moves to the top of the arc-shaped clamping block 1206, the arc-shaped clamping block 1206 will be popped out by the spring 1204, so as to clamp the tapered head 1103. Specifically, the tapered head 1103 is implemented as a conical or circular table type structure, which has a Figure 6 The annular inclined surface 11030 is shown, and the arc-shaped clamping block 1206 has an arc-shaped matching inclined surface 12060 matched therewith. The fixed block 1201 has an insertion hole for inserting the fixed shaft 1102. After the fixed shaft 1102 is inserted into the fixed block 1201 and reaches the top tapered head 1103, it abuts against the arc-shaped matching inclined surface 12060 of the arc-shaped clamping block 1206. Thus, the vertical force is decomposed by the inclined surface to form a horizontal pushing force against the arc-shaped clamping block 1206, compressing the spring 1204, and the arc-shaped clamping block 1206 retracts inwardly until the tapered head 1103 is ejected from the insertion hole, and the arc-shaped clamping block 1206 is separated from the tapered head 1103. After that, the spring 1204 pushes the arc-shaped clamping block 1206 out to position and fix the bottom of the tapered head 1103.
[0044] In this embodiment, the number of fixed shafts 1102 is at least two oppositely arranged, and the specific arrangement is as shown in the figure. Figure 6 As shown, the positioning of the tapered head 1103 and the arc-shaped clamping block 1206 at the symmetrical positions makes the clamping of the bottom fixing member 11 and the top fixing member 12 more stable.

The triangular plates 13 can increase the stability of the bottom frame body 801, and also increase the engagement connection between the steel bar floor body 1 and the horizontal bottom frame 8, so as to stabilize the position of the frame and prevent the loss of position when pouring concrete. The horizontal bottom frame 8 and the horizontal top frame (9) can also be removed after the initial setting of the steel bar floor body 1 in cooperation with the vertical frame (7).

[0048] Working principle:
[0049] When manufacturing thin floor slabs, firstly, the threaded sleeve 6 is rotated. The threaded sleeve 6 adjusts the spacing of the vertical ribs 2 inside the fixing sleeve 3 by engaging with the second threaded rod 5 and the first threaded rod 4, thus fixing the spacing of the vertical ribs 2 to prevent them from shifting during subsequent concrete pouring, which could affect the local strength of the steel fiber floor slab body 1. Then, a suitable frame is selected according to the floor slab specifications.

The frame 701 and the bottom frame 801 are fixed together. The triangular plate 13 on the inner side of the bottom frame 801 can keep the bottom frame 801 stable and increase the connection between the steel fiber floor slab body 1 and the bottom frame 801. Then, the second clip 902 in the horizontal top frame 9 is installed into the top of the clip 702, thereby fixing the frame body 701 and the top frame 901. After the frame is fixed, the horizontal keel 10 is installed to strengthen the weight of the steel fiber floor slab body 1. Then, the vertical keel 2 and the horizontal keel 10 are installed at the connection. Install the bottom fixing member 11 and the top fixing member 12 to fix the vertical keel 2 and the horizontal keel 10. First, insert the fixing shaft 1102 at the top of the fixing base 1101 into the interior of the fixing block 1201. The cone head 1103 will press the arc-shaped locking block 1206 to move backward. At the same time, the arc-shaped locking block 1206 presses the spring 1204 outside the limiting shaft 1203 through the sliding shaft 1205. The positioning shaft 1202 is used to limit the spring 1204. When the cone head 1103 moves to the top of the arc-shaped locking block 1206, the arc-shaped locking block 1206... The spring 1204 will pop out and lock it in place, thus completing the fixation of the vertical keel 2 and the horizontal keel 10, reducing the time for tying the reinforcing bars. Finally, the steel fiber body 14 can be sprinkled in when pouring concrete (or the steel fiber body 14 can be mixed with the concrete before pouring). This utility model solves the problem that the internal keel position is easy to shift when pouring thin floor slabs, avoids uneven bearing capacity in different areas of the floor slab, improves the quality of the floor slab, reduces the occurrence of defective products, and also saves floor slab production time and improves work efficiency.
