Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, and more specifically, to an auxiliary device for controlling the quality of concrete pouring in a closed cavity. Background Art

[0002] In the prior art, it is common to pour concrete in a closed cavity. Since the construction work space can only be accessed from the bottom of the closed cavity, the entire closed cavity will be completely closed after the template construction is completed.

[0003] During the construction process, the size of the top cavity in the closed cavity is often impossible to accurately measure in real time because the interior of the closed cavity is invisible, which can easily cause cavities in the top of the cavity or waste of concrete; the formed cavity greatly reduces the integrity of the concrete. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary device for quality control of closed cavity concrete pouring, which can effectively observe the fluidity of concrete during the pouring of closed cavity concrete, avoid the blockage of the grouting pipe during the concrete pouring process, and provide effective data for the subsequent grouting amount, thereby reducing the waste of grouting materials and reducing construction costs;

[0005] The solution adopted by the utility model to solve the technical problem is:

[0006] An auxiliary device for controlling the quality of concrete pouring in a closed cavity comprises a grouting pipe with one end extending into the closed cavity, a transparent protective cover connected to the end of the grouting pipe extending into the closed cavity, and a camera passing through the grouting pipe and located in the transparent protective cover; the end of the transparent protective cover away from the grouting pipe abuts against the top of the closed cavity.

[0007] When in use, after the formwork is completed, the grouting pipe is connected to the transparent protective cover, and one end of the grouting pipe and the transparent protective cover are extended into the closed cavity, and the end of the transparent protective cover away from the grouting pipe is abutted against the top of the closed cavity; then, concrete is poured through the pump pipe extended into the closed cavity. During the pouring process, a camera is passed through the grouting pipe and extended into the transparent protective cover, and the fluidity of the concrete poured in the closed cavity can be observed through the camera; after the concrete pouring is completed and before the initial setting, the transparent protective cover is taken out, and then the gap or cavity formed by the concrete and the closed cavity is grouted through the grouting pipe; due to the setting of the transparent protective cover, the situation that the grouting pipe is blocked by concrete during the concrete pouring process and grouting cannot be carried out in the later stage can be effectively avoided, and at the same time, the volume of grouting material required for subsequent grouting can be calculated by observing the transparent protective cover, thereby avoiding the waste of grouting material;

[0008] In some possible implementations, in order to effectively realize the connection between the transparent protective cover and the grouting pipe, the two can be effectively separated;

[0009] The transparent protective cover is in the form of a cylindrical sleeve structure, an internal thread is arranged at the end of the grouting pipe extending into the closed cavity, and an external thread used in conjunction with the internal thread is arranged on the outer side of the transparent protective cover.

[0010] In some possible implementations, in order to enable the transparent protective cover to be removed from the grouting pipe;

[0011] The transparent protective cover comprises a threaded section connected to the grouting pipe and provided with an external thread, and a protective section coaxially arranged with the threaded section and connected to each other; the outer diameter of the protective section is smaller than the outer diameter of the threaded section.

[0012] In some possible implementations, in order to effectively remove the transparent protective cover from the grouting pipe;

[0013] It also includes a disassembly assembly for removing the transparent protective cover from the closed cavity; the disassembly assembly includes a clamping groove arranged at one end of the threaded section away from the protective section, and a disassembly piece extending into the grouting pipe and clamped with the clamping groove.

[0014] In some possible implementations, the slot is in an L-shaped structure and includes a groove arranged axially along the thread segment and a transverse groove connected to a side surface of the groove to form an L-shaped structure.

[0015] In some possible implementations, the disassembly component includes an operating rod and a plug-in unit disposed at one end of the operating rod and used in conjunction with the card slot.

[0016] In some possible implementations, the plug-in includes a connecting rod arranged along the radial direction of the operating rod and connected to the outer side of the operating rod at one end, and an insert block arranged at one end of the connecting rod connected to the operating rod and used in conjunction with the transverse groove.

[0017] In some possible implementations, in order to make the insert block effectively cooperate with the slot, the threaded section is driven to rotate by twisting the operating rod, so that the transparent protective cover is taken out from the grouting pipe;

[0018] The distance between the end of the insert block away from the operating rod and the long axis of the operating rod is A, the outer diameter of the threaded section is D, the inner diameter of the threaded section is B, and B<A≤D.

[0019] In some possible implementations, the slots are in multiple groups and are evenly arranged along the circumference of the thread segment, and the number of the plug-ins is the same as that of the slots and they are arranged in a one-to-one correspondence.

[0020] In some possible implementations, the camera is externally connected to a video platform, and scale lines are also provided on the transparent protective cover along the axial direction of the grouting pipe.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model provides a transparent protective cover at the end of the grouting pipe. During the concrete pouring process, the fluidity of the concrete can be effectively observed by extending the camera through the grouting pipe into the transparent protective cover. At the same time, the provision of the transparent protective cover can effectively prevent the grouting pipe from being blocked by concrete during the concrete pouring process, thereby causing the grouting pipe to be unable to be normally grouted in the later stage.

[0023] By setting scale lines on the protection section and combining the structural dimensions of the closed cavity, the volume of the cavity or gap formed by all concrete and the top of the closed cavity can be effectively calculated, and the volume of grouting material used for the later grouting can be obtained, thus avoiding the waste of grouting material and reducing the construction cost.

[0024] The utility model arranges an internal thread in the grouting pipe to cooperate with the external thread of the threaded section, and makes the outer diameter of the protective section smaller than the outer diameter of the threaded section, so that the transparent protective cover can be effectively taken out of the grouting pipe, so that it does not affect the later grouting;

[0025] The utility model has a simple structure and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the height of the cavity can be observed by observing the scale line of the transparent protective cover 2, and the volume of grouting material required for subsequent grouting can be calculated in combination with the size of the closed cavity, thereby avoiding the waste of grouting material;

[0038] The camera 3 passes through the grouting pipe 1 and enters the transparent protective cover 2. Under the protection of the transparent protective cover 2, the camera 3 is prevented from being contaminated by the concrete slurry.

After the internal thread and the external thread are completely separated, the disassembly piece is pulled out of the closed cavity 10 to realize the removal of the transparent protective cover 2;
