Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a protective device for post-pouring strips in building construction. Background Technology

[0002] In the field of building construction technology, cracks often appear in beams, floor slabs, and other structural components during concrete pouring due to shrinkage and settlement. To prevent damage to the building and ensure its safety, post-pouring strips are used to seal these cracks. These post-pouring strips are formed through concrete pouring and require protective devices after pouring. These devices are removed once the concrete has hardened and solidified. This prevents damage to the post-pouring strip from factors such as trampling while the concrete is still uncured, and also prevents debris from entering the uncured concrete and compromising its quality.

[0003] Currently, post-cast strips are widely used in the construction field, and there are various types of protective devices for them. For example, Chinese utility model CN222066227U discloses a protective device for post-cast strips in construction. This device includes a base, a sliding mechanism fixedly installed on the base, and a lifting mechanism slidably connected to the sliding mechanism. The sliding mechanism includes a slide rail, a pulley slidably connected to the inner wall of the slide rail, a slider installed on the pulley, a positioning plate installed on the slider, a connecting bolt fixedly connected to the positioning plate, and a positioning bolt provided on the outer wall of the positioning plate. The lifting mechanism includes an arc-shaped slide, a support rod movably installed on the inner wall of the arc-shaped slide, rollers rotatably installed at both ends of the support rod, and a protective net connected to the outer wall of the support rod. When using this device, the protective net can be lifted by the lifting mechanism to maintain the post-cast strip, and the movement of the pulley in the slide rail can drive the lifting mechanism to move. The protective net of the lifting mechanism protects the post-cast strip to prevent damage.

[0004] Although the above-mentioned device can protect the post-cast strip, because the slide rails of the device are laid on both sides of the post-cast strip and the slide rails are open structures, and the open part of the slide rails is exposed outside, when the post-cast strip is formed by concrete pouring, concrete can easily enter the slide rails due to splashing and other reasons. After the concrete solidifies in the slide rails, it will block the movement of the pulleys, thus causing some inconvenience to use. Utility Model Content

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Example 1

[0034] like Figure 1 as well as Figure 2 As shown, this is a schematic diagram of the structure of the post-pouring strip protection device used in this embodiment. The protection device in this embodiment is used to protect the post-pouring strip A. After the concrete is poured to form the post-pouring strip A, the protection device in this embodiment covers the outside of the post-pouring strip A, avoiding the problem of damage to the post-pouring strip A caused by other factors, and also preventing external garbage from entering the post-pouring strip A, thus ensuring the quality of the post-pouring strip A.

[0035] In this embodiment, the protective device is formed by sequentially splicing multiple protective units 100, and the protective device is placed on the outside of the post-pouring strip A.

[0036] like Figure 3 as well as Figure 4 As shown, this is a structural schematic diagram of the protective unit 100 in this embodiment. The protective unit 100 in this embodiment includes a protective shell 101, which is a U-shaped frame structure. Both ends of the protective shell 101 are integrally formed and connected to connecting plates 102. In this embodiment, the protective device also includes a slider 103 and a track component 104. The slider 103 is fixedly connected to the connecting plate 102, and the slider 103 is slidably disposed in the track component 104. In this embodiment, the slider 103 can slide in the track component 104, thereby driving the protective shell 101 to move, and thus adjusting the position of the protective shell 101.

[0037] It is worth noting that in this embodiment, bolt holes are distributed on the side walls of the track component 104 and the slide bar 103. When the protective device is installed on the post-pouring strip A and the protective shell 101 needs to be fixed, the slide bar 103 and the track component 104 are fixed relative to each other by bolts, thereby fixing the protective shell 101. The protective shell 101 is installed on the outside of the post-pouring strip A to protect the post-pouring strip A.

[0038] It should also be noted that multiple track components 104 are provided in this embodiment. The track components 104 are laid sequentially on both sides of the post-pouring strip A, and the slide bar 103 is slidably assembled in the track component 104. Although the track component 104 is an open structure, the sliding device of the slide bar 103 is in the track component 104 and covers the opening of the track component 104, which can effectively prevent concrete from splashing into the opening of the track component 104 and causing inconvenience in use.

[0039] In this embodiment, the protective unit 100 is laid sequentially on the post-pouring strip A to shield and protect the post-pouring strip A, thus ensuring the quality of the post-pouring strip A.

[0040] Example 2

[0041] like Figure 5 as well as Figure 6 As shown, this is a schematic diagram of the protective device in this embodiment. The protective device in this embodiment is formed by sequentially splicing multiple adjusting covers 200. The adjusting cover 200 in this embodiment includes a connecting cover 201 and a movable cover 202. The end of the connecting cover 201 away from the movable cover 202 is connected to a connecting plate 102. The end of the movable cover 202 away from the connecting cover 201 is also connected to a connecting plate 102. A sliding strip 103 is connected to the bottom of the connecting plate 102. Track components 104 are laid on both sides of the post-pouring strip A. The sliding strip 103 and the track component 104 are slidably assembled. In this embodiment, the adjusting cover 200 is used to adjust the width of the adjusting cover 200 by cooperating with the connecting cover 201 and the movable cover 202, so as to be suitable for post-pouring strips A of different widths. After the width of the adjusting cover 200 is adjusted, the track component 104 is laid to facilitate the assembly of the sliding strip 103 and the track component 104.

[0042] In this embodiment, the connecting cover 201 and the movable cover 202 are slidably assembled, thereby facilitating the adjustment of the width of the adjusting cover 200.

[0043] like Figure 6As shown, in order to ensure the sliding assembly effect of the connecting cover 201 and the movable cover 202, in this embodiment, a fixing plate 203 is fixedly connected to the side of the movable cover 202 near the connecting cover 201. The fixing plate 203 and the connecting cover 201 are slidably assembled. Specifically, the connecting cover 201 in this embodiment has a waist hole 201a, and a fixing post 203a is fixedly connected to the fixing plate 203. The fixing post 203a passes through the waist hole 201a. When the fixing plate 203 slides relative to the connecting cover 201, the fixing post 203a moves along the length direction of the waist hole 201a to adjust the width of the adjusting cover 200.

[0044] In this embodiment, by adjusting the width of the adjusting cover 200, the adjusting cover 200 can be adapted to post-pouring strips A of different widths, thereby improving the practicality of the protective device.

[0045] like Figure 7 As shown, in order to ensure the strength of the protective device and avoid the problem of low pressure bearing capacity of the adjusting cover 200, in this embodiment, the adjusting cover 200 also includes a reinforcing member 204. The reinforcing member 204 is a rod-shaped structure, and one end of the reinforcing member 204 passes through the connecting cover 201, and the other end passes through the movable cover 202. A nut is threaded on the end of the reinforcing member 204, and the nut locks the reinforcing member 204 between the connecting cover 201 and the movable cover 202, thereby improving the pressure bearing effect of the adjusting cover 200 and preventing the adjusting cover 200 from being damaged or collapsed due to heavy objects falling on it. This further ensures the protective effect of the protective device on the post-pouring strip A.

[0046] It is worth noting that the reinforcement 204 in this embodiment can also be used in the protective device of embodiment 1. Specifically, the two ends of the reinforcement 204 pass through the side wall of the protective shell 101, and the reinforcement 204 is locked between the protective shells 101 by nuts.

[0047] In this embodiment and in Embodiment 1, the reinforcement 204 enhances the compressive strength of the protective unit 100, preventing damage or collapse of the protective unit 100 caused by external pressure. This ensures the practicality of the protective device, improves its protective performance for the post-pouring strip A, and enhances its protective effect on the post-pouring strip A, thus ensuring the quality of the post-pouring strip A formed after the concrete has set.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
