Background technique

At present, in the construction process of the CL building system, the pouring of concrete has the defects of difficult operation, waste of labor, waste of materials, and difficulty in controlling the quality of the project. During the concrete pouring process, due to the large amount of concrete engineering work, the concrete flows out of the pumping pipe with a fast flow rate and a large impact force, resulting in serious waste of concrete. More labor is required for concrete maintenance and post-concrete cleaning. The concrete is poured into the wall Finally, the internal EPS board is broken due to the excessive difference in the level of the concrete liquid level, which brings safety hazards to the building structure and affects the quality of the project.

The inward end of the first adjusting plate is vertically provided with a contact block. The top is provided with a stopper suitable for the contact block.

When the diversion ratio cannot be quickly adjusted by using the regulating valve, it is preferable to add the following regulating diversion device: an arc-shaped chute is arranged on the vertical main direction square pipe, a sealing gasket is fixed at the upper and lower ends of the arc-shaped chute, and two The sealing pads intersect; the top of the stopper is hinged with a second adjusting plate, the upper end of the second adjusting plate can slide back and forth along the intersecting arc curve of the two sealing pads between the arc-shaped chute, and the upper end of the second adjusting plate is in the vertical main direction. A handle is fixed outside the tube. Among them, the two gaskets intersect and are in a closed state, which can effectively avoid concrete splashing; when it is necessary to adjust the split ratio, just push the handle, and then drive the top of the second adjustment plate to peel off the intersecting arc curve of the two gaskets, and go back and forth along it Slide it until it is in the right position, and fix the handle.

The connection mode between the vertical main guiding square tube and the two oblique branch guiding circles is preferably as follows: a folding plate is fixed on the inner wall of the lower end of the vertical main guiding square tube, and the two oblique branch guiding circular tubes pass through the folding plate symmetrically. Connected to the lower end of the vertical main direction square pipe.

Preferably, in order to quickly and tightly fix the diverter of the present invention and the concrete pumping pipe, the upper end of the fixing collar is preferably a buckle, so that the concrete pumping pipe can be directly inserted into the fixing collar, and then the buckle can be fixed with screws.

Preferably, a plurality of reinforcing ribs are evenly fixed on the outer wall between the upper end and the lower end of the fixing collar.

Preferably, the vertical branch guide tube and the rubber tube are fixedly connected by a quick release tool.

Preferably, the quick release tool is a clamp.

The diverter of the invention can not only divert the concrete reaching the inside of the wall in proportion, but also slow down the flow velocity of the concrete, reduce waste of concrete resources and improve work efficiency.

Example 1

As shown in Figure 1-5, a concrete diverter: includes a circular platform-shaped fixed collar 1 that is thinner at the top and thicker at the bottom. The lower end of the fixed collar 1 is welded with a diverter funnel 2. The delivery pipe is matched, the lower end is matched with the upper end of the diverting funnel 2, eight reinforcing ribs 3 (round steel) are uniformly welded on the outer wall between the upper end and the lower end of the fixed collar 1, and a vertical leading rib is welded at the lower end of the diverting funnel 2 To the square tube 4, two support blocks 5 are welded on the inner wall of the upper end of the vertical main guide square tube 4, and the upper ends of the two support blocks 5 are welded with a flow reducing net 6, and the lower end inner wall of the vertical main guide square tube 4 is welded with a fold Shaped plate 7, the lower end of the vertical main guide square tube 4 is symmetrically welded to two oblique branch guide tubes 8 through the folded plate 7 and the adjacent sides of the upper ends of the two oblique branch guide tubes 8 are connected. A vertical branch guide tube 9 is respectively welded to the lower end of the branch guide tube 8, and the two vertical branch guide tubes 9 are fixedly connected to a rubber tube 11 through a clamp 10; the bottom of the vertical main guide square tube 4 There are two regulating valves 12 symmetrically arranged at the end, and the regulating valve 12 is composed of an upper fixing plate 121, a lower fixing plate 122 and a first adjusting plate 123, and the upper fixing plate 121 and the lower fixing plate 122 are welded and fixed on the vertical main guide respectively. On the outer side of the bottom of the square tube 4, the first adjusting plate 123 is inserted between the upper fixing plate 121 and the lower fixing plate 122 and passes through the vertical main direction square tube 4, and the inward end of the first adjusting plate 123 is vertically formed integrally with it.
