Technical Field

The utility model relates to a building engineering field specifically is a pouring auxiliary device that is used for floor to reserve between hole and drain pipe.

Background

The leakage-proof method for the drainage pipe through the floor slab is an important part of field construction, and when the leakage-proof construction is carried out on the traditional floor slab, a pipe hole mold hanging method is generally adopted to plug a gap at a position where a hole is reserved in the floor slab and a drainage pipe is installed, namely a template is fixed on the bottom surface layer of the floor slab firstly, and then the template is fixed on the upper layer of the floor slab by using thin aluminum wires and steel bars. The traditional method is complex in process and long in time consumption, the situation that plugging is not in place easily occurs at a wire binding position, a scaffold is required, certain potential safety hazards exist during ascending, and therefore the plugging mode is slowly separated from the sight of people.

With the gradual development of modern buildings, various novel gap plugging methods appear on construction sites in succession, but the problems of inconvenient construction, poor seepage prevention effect and the like still exist.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, construction convenience's a pouring auxiliary device that is used for the floor to reserve hole and between drain pipe to can realize reserving the effective shutoff in gap between hole and drain pipe to the floor before pouring cement mortar.

The utility model adopts the technical proposal that: a pouring auxiliary device used between a reserved hole of a floor slab and a drain pipe is structurally characterized by comprising a first shaping device and a second shaping device which are matched with each other, wherein the first shaping device and the second shaping device are oppositely arranged on two sides of the drain pipe and surround the outer wall of the drain pipe when in use; the bottom of the first shaping device is provided with a first supporting rod, and the bottom of the second shaping device is provided with a second supporting rod.

Because the shape taking device can be completely attached to the outer wall of the drain pipe, before cement mortar is poured, the two shape taking devices are oppositely arranged and surrounded on the outer wall of the drain pipe through the first supporting rod and the second supporting rod, a gap between a reserved hole of a floor slab and the drain pipe is completely plugged, and preparation work before cement mortar is poured is well carried out.

Preferably, one end of the first support rod is connected with the first mould extractor, and the other end of the first support rod is connected with the lower support; one end of the second supporting rod is connected with the second mould extractor, and the other end of the second supporting rod is installed on the first supporting rod through a connecting rod.

Preferably, a rotatable ring is arranged on the first supporting rod, and a clamping pin is arranged on the ring; one end of the connecting rod is fixedly connected with the second supporting rod, and the other end of the connecting rod is fixed on the circular ring.

In the above scheme, the position of second bracing piece is convenient for adjust as required to rotatable ring for two types of getting the type ware can enclose completely on the drain pipe outer wall, after getting the type ware and targetting in place, through bayonet lock fixed ring, avoid getting the type ware position to take place the skew in the work progress.

Preferably, the first supporting rod is a telescopic rod, and the circular ring is arranged at the telescopic position of the first supporting rod, so that the height of the shape taking device can be adjusted according to the requirement, and the two shape taking devices are ensured to be positioned on the same plane.

Preferably, the connection rod is made of a steel pipe having a curvature so as to prevent the connection rod from contacting the drain pipe.

Preferably, the first support rod and the second support rod are both made of steel pipes.

The utility model has the advantages that:

1. by utilizing the characteristic that the shape-taking device can be completely attached to the outer diameter of the water pipe, the gap between the reserved holes of the water drainage pipe and the floor slab can be reliably plugged before cement mortar is poured;

2. the first supporting rod is arranged as a telescopic rod, so that construction is carried out only by standing on the ground during site construction, and conversion between an upper floor and a lower floor is not needed, and the construction time is shortened;

3. the lifting tool such as a scaffold is not needed, and the lifting tool is safer for constructors.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 3, an auxiliary pouring device for use between a reserved hole of a floor slab and a drain pipe includes a first shape extractor 11 and a second shape extractor 12, the first shape extractor 11 is fixed at one end of a first supporting rod 2, and the other end of the first supporting rod 2 is fixed on a lower support 5. The first supporting rod 2 is further sleeved with a rotatable circular ring 8, a clamping pin 9 is arranged on the circular ring 8, and the clamping pin 9 is used for fixing the circular ring 8. The second shaper 12 is fixed to one end of the second support rod 3. The other end of the second support rod 3 is fixed on the circular ring 8 through a connecting rod 4. When the drainage device is used, the lower support 5 is supported on the upper surface of a lower floor slab, the first shaping device 11 and the second shaping device 12 are attached to the lower surface of the upper floor slab 6, and the first shaping device 11 and the second shaping device 12 completely surround the drainage pipe 7, so that subsequent construction is facilitated.

In this embodiment, the first support rod 2 may be configured as a telescopic rod, and the ring 8 is configured at the telescopic position of the first support rod 2. Like this, when the site operation, the workman only need stand and can be under construction on ground, and need not to use ascending tools such as scaffold, has shortened the engineering time.

Since the first and

second swagers

11 and 12 are disposed opposite to each other and surround the outer wall of the drain pipe, the connecting rod 4 is made of a steel pipe having a certain curvature to prevent the connecting rod 4 from contacting the drain pipe 7.

In this embodiment, the first support bar 2 and the second support bar 3 are both made of steel pipes.

When the first and

second swagers

11 and 12 of this embodiment are pressed toward the drain pipe 7, the first and

second swagers

11 and 12 may become arc-shaped notches along the outer diameter of the drain pipe 7, so as to surround the drain pipe 7, and the two swagers just may completely surround the outer wall of the drain pipe 7. The first and

second strippers

11 and 12 are commercially available products.

During construction, the first supporting rod 2 is close to one side of the drain pipe 7, the first shaping device 11 above the first supporting rod can be completely attached to one half of the circumference of the drain pipe 7, then the circular ring 8 is rotated until the second shaping device 12 is completely attached to the other half of the circumference of the drain pipe 7, then the circular ring 8 is fixed by the clamping pin 9 and is not rotated, and then the lower support 5 is adjusted, so that the first shaping device 11 and the second shaping device 12 can be completely attached to the lower surface of the upper floor slab 6. At the moment, the two shaping devices realize reliable plugging of the gap between the reserved holes of the drain pipe 7 and the upper floor 6, so that the pouring work of cement mortar is facilitated.
