Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a bidirectionally adjustable fixed mold for pre-embedded pipe clamps in concrete floors. Background Art

[0002] The dominant drainage pipe construction technology today collects water from various water collection points, passes it through the floor slab, and then collects it through drainage branches installed below the floor slab to the drainage riser, thereby discharging domestic sewage. Therefore, during the main structure construction process, holes for pipe installation at each water collection point must be reserved in the floor slab. After the pipes are installed, the holes are sealed. The main problem with this traditional construction method is that the gap between the reserved holes and the pipes is small, making it difficult to fill tightly and easily creating a potential leak. Therefore, pre-buried pipe clamps are naturally introduced during the construction process.

[0003] The utility model patent with announcement number CN206554506U proposes a bidirectional adjustable fixed mold for embedded pipe clamps of concrete floor slabs, which includes a circular steel plate, a mounting hole, a round steel, a lined steel pipe mold and a bottom mold plate; the upper end of the round steel is provided with an upper thread, the lower end of the round steel is provided with a lower thread, an upper tightening nut is fixedly provided at the top end of the upper thread, a lower tightening nut is fixedly provided at the top end of the lower thread, and a base nut is fixedly provided on the upper side of the mounting hole, and the upper thread cooperates with the base nut.

[0004] One of the above-mentioned concrete floor embedded pipe clamps uses a two-way adjustable fixed mold, which slides inside the embedded pipe clamp through the inner lining steel pipe mold to be suitable for pouring floor tops of different elevations, avoiding the problem that the height of the embedded pipe clamp cannot be adjusted, resulting in reduced applicability of the mold. This application provides another solution to this problem. Utility Model Content

[0013] Optionally, an annular rubber pad is placed in the annular sealing groove on the annular baffle, and the annular rubber pad is sleeved on the rotating rod.

[0014] By adopting the above technical solution, after the annular baffle is inserted into the annular sealing groove, the rotating rod is threadedly connected to the annular baffle by rotating the rotating rod, so that the annular baffle can move in the annular sealing groove, squeezing the annular rubber pad, thereby improving the sealing performance of the annular baffle and the annular sealing groove.

[0021] Optionally, a fastening bolt is provided at the top end of the second pipe clamp, and an output end of the fastening bolt passes through the top template and the bottom template and is threadedly connected with a second nut.

[0022] By adopting the above technical solution, the output end of the fastening bolt is passed through the top template, the second pipe clamp, the first pipe clamp and the bottom template, and then the second nut is threadedly connected to the fastening bolt so that the second nut abuts against the bottom template, thereby improving the stability of the first pipe clamp and the second pipe clamp.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] See also Figure 1-3 A bidirectionally adjustable fixed mold for a pre-buried pipe clamp of a concrete floor comprises a first pipe clamp 1 and a second pipe clamp 2. A sealing adjustment assembly for adjusting the distance between the first pipe clamp 1 and the second pipe clamp 2 is provided between the first pipe clamp 1 and the second pipe clamp 2. The sealing adjustment assembly comprises an annular baffle 3, an annular chute 4, and a bellows 5.

[0033] A connecting assembly is provided between the annular baffle 3 and the second pipe clamp 2. The annular baffle 3 is installed at the bottom end of the second pipe clamp 2 through the connecting assembly. The annular chute 4 is opened at the top of the first pipe clamp 1. The end of the annular baffle 3 away from the second pipe clamp 2 is slidably set in the annular chute 4. The top of the bellows 5 is fixedly connected to the bottom end of the annular baffle 3, and the end of the bellows 5 away from the annular baffle 3 is fixedly connected to the bottom wall of the annular chute 4.

[0034] During use, according to the thickness of the concrete floor, pull the first pipe clamp 1 and the second pipe clamp 2 to move the first pipe clamp 1 and the second pipe clamp 2 away from each other, move the annular baffle 3 in the annular chute 4, and adjust the distance between the first pipe clamp 1 and the second pipe clamp 2. At the same time, when the annular baffle 3 moves in the annular chute 4, the corrugated tube 5 will be unfolded, so that the concrete during pouring cannot penetrate through the gap between the annular chute 4 and the annular baffle 3, thereby avoiding the problem that the height of the embedded pipe clamp cannot be adjusted, which reduces the applicability of the mold.

[0035] Reference Figure 2 and Figure 3 The bottom wall of the annular chute 4 is fixedly connected with a plurality of positioning posts 6 in an annular array. The positioning posts 6 are located inside the bellows 5. The bottom end of the annular baffle 3 is located inside the bellows 5 and is provided with a plurality of positioning holes 7 in an annular array. The positioning posts 6 are slidably arranged in the positioning holes 7. Through the positioning posts 6 and the positioning holes 7, the sliding stability of the annular baffle 3 in the annular chute 4 can be improved, so that the first pipe clamp 1 and the second pipe clamp 2 remain vertical.

The bottom ends of the rotating rods 9 pass through the second pipe clamp 2 and are threadedly connected to the annular baffle 3. The rotating rods 9 are rotatably connected to the second pipe clamp 2. By simultaneously rotating the rotating rods 9 to disconnect the annular baffle 3 from the rotating rods 9, the annular baffle 3 can be disconnected from the second pipe clamp 2, which facilitates the disassembly of the first pipe clamp 1 and the second pipe clamp 2.

[0037] Reference Figure 4 A circular rubber pad 10 is placed on the circular baffle plate 3 in the circular sealing groove 8, and the circular rubber pad 10 is sleeved on the rotating rod 9. After the circular baffle plate 3 is inserted into the circular sealing groove 8, the rotating rod 9 is threadedly connected to the circular baffle plate 3 by rotating the rotating rod 9, so that the circular baffle plate 3 can be moved in the circular sealing groove 8, squeezing the circular rubber pad 10, so that the circular rubber pad 10 is deformed and fits more closely with the circular baffle plate 3 and the circular sealing groove 8, thereby improving the sealing between the circular baffle plate 3 and the circular sealing groove 8.

The distance between the two pipe clamps 2 is adjusted, and when the annular baffle 3 moves in the annular chute 4, the corrugated tube 5 will be expanded, so that the concrete during pouring cannot penetrate through the gap between the annular chute 4 and the annular baffle 3, and then the top template 13 is put on the threaded rod 12, and the top template 13 is fit with the top of the second pipe clamp 2 by rotating the first nut 14. At the same time, the lower surface of the top template 13 is fit with the top of the floor slab, so as to maintain the stability of the mold when in use and avoid the problem that the height of the embedded pipe clamp cannot be adjusted, which reduces the applicability of the mold.
