DETAILED DESCRIPTION

[0020] The utility model is further described below.

[0021] The utility model provides a support frame for assisting the plugging of a hole of a pipe passing through a floor slab, which is mainly used for assisting the construction of plugging a hole of a pipe passing through a floor slab. The support frame comprises a clamp 1 for installing a pipe and a telescopic support mechanism 2. The telescopic support mechanism 2 is at least three groups and is evenly spaced and arranged on the outer ring of the clamp 1. The clamp 1 comprises a first hoop body 11 and a second hoop body 12, both of which are semicircular. One end of the first hoop body 11 and the second hoop body 12 are hinged. A first ear plate 111 is arranged on the outer side of the other end of the first hoop body 11, and a second ear plate 121 is arranged on the outer side of the other end of the second hoop body 12. The first ear plate 121 is arranged on the outer side of the second hoop body 12. A bolt 13 is provided in the plate 111 and passes through the second ear plate 121 and is hinged to the first ear plate 111. The first hoop body 11 and the second hoop body 12 enclose a pipe installation cavity. A butterfly knob 131 is provided at one end of the bolt 13 extending out of the second ear plate 121. The telescopic support mechanism 2 includes a first rod member 21 and a second rod member 22. The first rod member 21 is hinged to the clamp 1. The first rod member 21 is a hollow structure. The second rod member 22 is slidably connected to the first rod member 21. A fixing member 3 for locking the second rod member 22 is provided between the first rod member 21 and the second rod member 22.

[0022] like Figure 1 As shown, the support frame for assisting the plugging of the hole of the pipeline passing through the floor provided by the utility model comprises a clamp 1 and a telescopic support mechanism 2, wherein the telescopic support mechanism 2 is evenly arranged on the outer ring of the clamp 1, and the number of the telescopic support mechanism 2 is at least three groups to ensure stable support for the clamp 1, and can also be set to four or five groups. The specific number can be selected according to the actual situation. Under the condition of ensuring the support stability, Figure 1Three groups of telescopic support mechanisms 2 are arranged at equal angles on the circumference; in order to facilitate the installation of the clamp 1 for pipes of various sizes, the clamp 1 includes a first hoop body 11 and a second hoop body 12, the first hoop body 11 and the second hoop body 12 are semicircular and can enclose a pipe installation cavity, one end of the first hoop body 11 and the second hoop body 12 are hinged so that the first hoop body 11 and the second hoop body 12 can rotate, and then they are arranged on the pipe 6, and the first hoop body 11 and the second hoop body 12 are fixed to the pipe 6 by bolts 13 arranged on the first ear plate 111 and the second ear plate 121; The telescopic support rod comprises a first rod 21 and a second rod 22. The first rod 21 is hinged to the outer ring of the clamp 1 through a hinge seat 211, so that the first rod 21 can rotate along the hinge seat 211, thereby achieving the purpose of adjusting the inclination angle between the telescopic support mechanism 2 and the clamp 1; the second rod 22 is slidably arranged in the first rod 21. Specifically, the first rod 21 is a hollow structure, so that the second rod 22 can be slidably arranged in the first rod 21, thereby achieving the purpose of adjusting the telescopic length, and the second rod 22 is locked by the fixing member 3 so that the telescopic length is fixed, thereby achieving the purpose of telescopic fixation; Figure 1 , Figure 3 , Figure 4 As shown, when a support frame for assisting in plugging a hole of a pipe penetrating a floor slab is used, the first hoop body 11 and the second hoop body 12 are opened, and the first hoop body 11 and the second hoop body 12 are enclosed on the pipe 6, and the bolt 13 arranged on the first ear plate 111 and the second ear plate 121 is driven to rotate by screwing the butterfly knob 131, so that the first hoop body 11 and the second hoop body 12 are tightened, and the clamp 1 is locked on the pipe 6, and then the inclination angle and length of the telescopic support mechanism 2 outside the clamp 1 are adjusted to adjust the verticality and stability of the pipe 6. At the same time, the support frame is erected on the periphery of the pipe hole to be plugged, and the pipe 6 is located at the center of the pipe hole, and the pipe 6 is fixed. A certain upward pulling force is applied to prevent it from sliding down or tilting, so that it is always located in the center of the pipeline hole; then the hanging formwork 5 is applied under the floor slab 4, and by locking the pipeline 6, it is ensured that the pipeline 6 will not slide down or tilt, thereby ensuring that the hanging formwork 5 connected to the pipeline 6 will not slide down, so that in the process of sealing the pipeline hole, the hanging formwork 5 is always in contact with the floor slab 4, and leakage of slurry will not occur; the pipeline 6 and the hanging formwork 5 are supported as a whole by the clamp 1 and the telescopic support mechanism 2, so that the pipeline 6 will not tilt in the process of sealing the pipeline hole, ensuring the tightness of the hanging formwork 5 and the floor slab 4, avoiding the occurrence of slurry leakage, and ensuring the flatness of the floor slab 4 after the pipeline hole is sealed.

[0023] The fixing member 3 can be an existing bolt, that is, a pair of threaded holes symmetrically arranged along the axis of the first rod 21 are opened on the first rod 21, and the bolts pass through the first rod 21 and abut against the second rod 22. When the second rod 22 slides to the desired position, the bolts are screwed into the first rod 21 to tighten the second rod 22, and the second rod 22 can be locked by the tightening limit on the left and right sides. As a preferred method, Figure 2 As shown, the fixing member 3 used in the support frame includes a first sleeve 31 and a second sleeve 32, the first sleeve 31 is fixedly arranged at the lower end of the first rod 21, the first sleeve 31 is provided with an external thread, the second sleeve 32 is sleeved on the outside of the first sleeve 31 and is threadedly connected to the first sleeve 31, the second rod 22 is sleeved with an extrusion block 33 and the extrusion block 33 is arranged between the second sleeve 32 and the second rod 22, and the extrusion block 33 is an elastic member; when in use, the first sleeve 31 is first fixedly arranged at the lower end of the first rod 21, and the second sleeve 32 is threadedly arranged on the outside of the first sleeve 31, the extrusion block 33 is sleeved on the second rod 22 and is located between the second sleeve 32 and the second rod 22, when the second rod 22 slides to the desired height, the second sleeve 32 is rotated to make the second sleeve 32 move relative to the second rod 22 to the extrusion block 33, and the second sleeve 32 generates pressure on the extrusion block 33, so that the extrusion block 33 moves toward the second rod The second rod 22 is deformed, the extrusion block 33 is completely fitted with the second rod 22, and due to the pressure of the second sleeve 32, the extrusion block 33 completely presses the second rod 22, thereby increasing the friction between the extrusion block 33 and the second rod 22, thereby achieving the purpose of locking and fixing the second rod 22, and the second rod 22 can be locked on the first rod 21 by the second sleeve 32 and the extrusion block 33 that cooperate with each other at any telescopic length; the fixing member 3 using this structure can also make the connection between the first rod 21 and the second rod 22 more stable and withstand greater pulling force and pressure; when it is necessary to adjust the telescopic length of the second rod 22 relative to the first rod 21, the second sleeve 32 is rotated onto the first sleeve 31 to release the extrusion of the extrusion block 33. Since the extrusion block 33 is an elastic member, specifically rubber, it can automatically restore to its original state and no longer be tightly attached to the second rod 22, thereby allowing the second rod 22 to slide relative to the first rod 21 again to adjust the telescopic length.

[0024] To strengthen the upward pressure of the extrusion block 33 on the second rod 22, as shown in FIG. Figure 2As shown, the lower end of the extrusion block 33 is provided with an inclined surface, and the second sleeve 32 is provided with a first inclined surface 34 that matches the inclined surface; when the second sleeve 32 rotates to the lower end of the extrusion block 33, the first inclined surface 34 fits with the inclined surface, and the second sleeve 32 applies upward pressure to the extrusion block 33, thereby causing the extrusion block 33 to apply upward pressure to the second rod 22 to prevent the second rod 22 from sliding down due to excessive pressure from above; at the same time, the extrusion block 33 not only generates extrusion force on the second rod 22, but also generates extrusion force on the second sleeve 32, so when the first inclined surface 34 fits with the inclined surface, no relative sliding will occur among the second sleeve 32, the extrusion block 33, and the second rod 22.

[0025] In order to make the extrusion block 33 play an anti-slip role when clamping the second rod 22, when the extrusion block 33 is released, the inner wall of the extrusion block 33 will not be too tightly attached to the second rod 22, so as to facilitate the telescopic adjustment of the second rod 22; the contact surface between the extrusion block 33 and the second rod 22 is provided with a frosted layer.

[0026] In order to ensure that the support frame of the present application can be further adjusted after being installed on the pipe 6, an upward force is further applied to the pipe 6 so that the hanging formwork 5 below the hole to be blocked fits tightly with the floor slab 4, such as Figure 1 , Figure 3 and Figure 4 As shown, the telescopic support mechanism 2 also includes a third rod 23, the upper end of the third rod 23 is provided with a threaded section 231, the lower end of the second rod 22 is provided with an internal thread, and the third rod 23 is threadedly connected to the lower end of the second rod 22; because the support frame has been matched with the pipe 6 and the floor 4 at this time, the second rod 22 and the first rod 21 have been locked by the fixing member 3. For further adjustment, the third rod 23 is set at the lower end of the second rod 22. Since the adjustment at this time does not require a large adjustment , only fine-tuning is needed to further apply upward force to the pipe 6, so the third rod 23 and the second rod 22 are connected by a threaded connection; because the second rod 22 has been locked with the first rod 21, an internal thread is provided at the lower end of the second rod 22, and a threaded section 231 is provided at the upper end of the third rod 23. By screwing the third rod 23 to adjust the installed support frame, an upward force is further applied to the pipe 6, so that the hanging formwork 5 below the hole to be blocked is closely attached to the floor 4, avoiding leakage or uneven floor 4.

[0027] To facilitate the screwing of the third rod 23, Figure 1 As shown, the third rod 23 is fixed with a nut 232. When adjustment is needed, it can be screwed with a wrench adapted to the nut 232, which is convenient for force application. To ensure the stability of the entire support frame, Figure 1As shown, a cone tip 233 is provided at the lower end of the third rod 23 , so that the support frame can be stably fixed on the floor 4 .

[0028] In order to reduce the gap between the clamp 1 and the pipe 6 and ensure the firmness of the clamp 1 when it is installed on the pipe 6, as shown in FIG. Figure 1 As shown, the inner ring of the clamp 1 is provided with a groove 14, and a rubber ring is provided in the groove 14; the inner ring of the clamp 1 is provided with the groove 14, that is, grooves are provided on the first hoop body 11 and the second hoop body 12, and the grooves on the first hoop body 11 and the second hoop body 12 can be connected to form a circle, so that a rubber ring can be provided in the groove 14; when the butterfly knob 131 is screwed to adjust the pipeline installation cavity formed by the first hoop body 11 and the second hoop body 12 to a tightness that can be adapted to the pipeline 6, the elasticity of the rubber ring is utilized to make the clamp 1 and the pipeline 6 completely pressed against each other, reducing the gap therebetween, thereby ensuring the firmness of the clamp 1 when installed on the pipeline 6, thereby ensuring the installation stability of the pipeline 6 will not move with the hanging mold 5 due to the change in the weight of the concrete poured below, and at the same time, it is also ensured that the hanging mold 5 will not move.

[0029] In order to ensure the stability and reusability of the support frame, the telescopic support mechanism 2 is made of steel.
