Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Example 1: the utility model provides a concrete spreader split heads for building, as shown in figure 1, including the support frame of level setting, as shown in figure 3, the support frame includes 500mm 600 mm's square frame 1 and the cross 3 that forms by the welding of two strip-shaped steel sheets that is formed by four 50mm angle steel head and the tail welding, cross 3 establishes in frame 1 and with frame 1 welded connection, the support frame that frame 1 and cross 3 are constituteed forms field style of calligraphy structure.

As shown in fig. 2, vertical steel pipes are welded at four corners of the side frame 1 to form legs I2, and the length of the steel pipes is equal to the thickness of the floor slab +50 mm. After the steel pipe is welded with the side frame 1, concrete is poured into the steel pipe, the strength of the supporting leg is further improved, and the stability of the split heads in use is further enhanced.

As shown in FIG. 3, a through-hole 4 is provided at the center of the cross 3. A limiting vessel 5 is arranged above the cross 3, and the limiting vessel 5 is used for placing the supporting legs of the distributing machine and limiting the horizontal movement of the supporting legs of the distributing machine.

As shown in fig. 2 and 4, the limiting vessel 5 has a vessel structure with an upper opening, and the horizontal section of the limiting vessel 5 has a circular structure.

The bottom of the limiting vessel 5 is fixedly provided with a vertical pin rod 8, the pin rod 8 is rotatably inserted in the shaft hole 4, and the lower end of the pin rod 8 extends to the lower part of the cross 3. Be equipped with the external screw thread on the lateral wall of the lower part of pin 8, the 8 lower parts of pin are equipped with external screw thread complex second nut 9, and the diameter of second nut 9 is greater than the internal diameter in shaft hole 4, and second nut 9 is used for preventing that pin 8 from deviating from shaft hole 4.

As shown in fig. 1 and 4, three jacking members capable of adjusting length and used for jacking the supporting legs of the distributing machine are arranged on the vertical side wall of the limiting vessel 5 at equal intervals along the circumferential direction.

The tight component in top includes stop screw 7 and with stop screw 7 screw-thread fit's first nut 6, is equipped with three screw along circumference equidistance on the vertical lateral wall of spacing household utensils 5, the quantity and the tight component one-to-one in top of screw, all weld on the vertical lateral wall of every screw department has a first nut 6. The axes of all the limiting screws 7 are intersected at the center of the limiting vessel 5.

Spacing household utensils 5 are established to can pivoted structure because the split heads is when placing, because construction site's complexity, can lead to the landing leg of cloth machine to put into spacing household utensils 5 after, the landing leg top that current angle's limiting screw 7 can not be fine to the cloth machine leans on the application of force, consequently just need rotatory spacing household utensils 5, adjusts limiting screw 7 to suitable angle.

The working principle is as follows: before the floor concrete is poured, the four split heads are placed at proper positions of a floor, when the four split heads are placed, the supporting legs I2 at the lower parts of the split heads are kept to penetrate through gaps between the steel bars and the embedded pipelines (boxes), the supporting legs I2 are not in contact with the steel bars and the embedded pipelines (boxes), and the lower ends of the supporting legs I2 fall on the floor formwork. Then, four legs of the distributing machine are placed in a limiting vessel 5 on a stool.

If the bottom of the landing leg of the material distributor is of a circular or oval structure, the limiting screw 7 is directly screwed, so that the limiting screw 7 tightly pushes the lower end of the landing leg of the material distributor to limit the movement of the landing leg of the material distributor.
