Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, and in particular to a protective device for reserved holes in building construction. Background Technology

[0002] Pre-reserved holes in building construction refer to holes that are pre-cut in concrete structures (such as floor slabs, walls, beams, columns, etc.), masonry, or other building components according to design requirements or construction needs during the building construction process. These holes are not defects caused by construction errors, but are intentionally reserved to meet the needs of subsequent building functions, equipment installation, or construction techniques, and are a common structural treatment method in building construction.

[0003] In existing technologies, conventional pre-reserved holes in building construction, such as holes pre-reserved in concrete structures (e.g., floor slabs, walls, beams, columns), masonry, or other building components, can be protected by caps or shaft structures to prevent other objects from entering. However, in building construction, during foundation construction or the construction of pipe wells, larger circular pre-reserved holes are often made. These pre-reserved holes cannot be simply filled with caps or shaft structures, as this can easily cause the caps or shaft structures to fall into the holes. Utility Model Content

[0004] In view of this, the present invention provides a protective device for reserved holes in building construction. The main technical problem to be solved is that conventional caps or shaft structures cannot be inserted into the large circular reserved holes opened during foundation construction or pipeline well construction, and are prone to falling into the reserved holes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective device for reserved holes in building construction, comprising a cover, a bushing fixedly connected to the upper surface of the cover, a through hole opened inside the cover, the through hole being located below the bushing, a lead screw threadedly connected inside the bushing, the lead screw passing through the bushing and the through hole, a fixing sleeve fixedly connected to the inner wall of the cover, the fixing sleeve being located below the through hole, the lead screw passing through the inside of the fixing sleeve, a connecting plate movably connected to the outer wall of the lead screw, and four sets of support components installed on the outer wall of the fixing sleeve, each support component comprising a support plate, an ear seat one fixedly connected to the inner wall of the support plate, a connecting rod one rotatably connected inside the ear seat one, an ear seat two rotatably connected to the outer wall of the connecting rod one, the ear seat two fixedly connected to the outer wall of the connecting plate, two ear seats three fixedly connected to the inner wall of the support components, a connecting rod two rotatably connected inside each of the two ear seats three, an ear seat four rotatably connected to the outer wall of each of the two connecting rods two, and two ear seats four fixedly connected to the outer wall of the fixing sleeve.

[0006] By adopting the above technical solution, the cover is placed over the large circular pre-drilled hole opened during foundation construction or pipeline wellhead construction. Four sets of support components are placed inside the pre-drilled hole. Rotating the lead screw causes it to move downward, which in turn causes the connecting plate to move downward. After the connecting plate moves downward, it causes the end of the lug 2 connected to the connecting rod 1 to move downward, and causes the connecting rod 1 to rotate. This, in turn, pushes the lug 1 and the support plate outward. During the outward movement of the support plate, it also causes the two lug 3 to move and causes the connecting rod 2 to rotate. Thus, the outer wall of the support plate is supported by the inner wall of the large circular pre-drilled hole. In this way, the support components support the inner wall of the pre-drilled hole, causing the cover to be placed above the pre-drilled hole and confined to a position above the pre-drilled hole. This protects the large circular pre-drilled hole opened during foundation construction or pipeline wellhead construction, preventing objects from falling into the pre-drilled hole and also preventing workers from accidentally falling into the pre-drilled hole.

[0007] As a further description of the above technical solution: a throttle is fixedly connected to the top of the lead screw, and slide rods are fixedly connected to both sides of the upper surface of the connecting plate, with the slide rods slidably connected inside the fixed sleeve.

[0008] By adopting the above technical solution, the screw is driven to rotate by the throttle, and the screw rotation causes the connecting plate to move downward. During the downward movement of the connecting plate, it is limited by the slide rod and slides inside the fixed sleeve to prevent the connecting plate from rotating.

[0009] As a further description of the above technical solution: two ear seats are disposed above the ear seat one, one of the ear seats is disposed at the middle position of the inner wall of the support plate, and the other ear seat is disposed at the upper position of the inner wall of the support plate.

[0010] By adopting the above technical solution, two ear bases are arranged vertically above ear base one.

[0011] As a further description of the above technical solution: one of the ear seats is located at the lower position of the outer wall of the fixing sleeve, and the other ear seat is located at the upper position of the outer wall of the fixing sleeve.

[0012] By adopting the above technical solution, the two ear seats are arranged vertically on the outer wall of the fixing sleeve.

[0013] As a further description of the above technical solution: two ring plates are fixedly connected to the outer wall of the cover, and four sets of handles are fixedly connected to the outer wall of the two ring plates. Each set of handles consists of two handles, and the four sets of handles are arranged in an array on the outer wall of the two ring plates.

[0014] By adopting the above technical solution, the cover is moved by four sets of handles and placed over the larger circular reserved hole opened during the foundation construction or pipeline well construction, with the lower surface of one of the ring plates in contact with the ground.

[0015] As a further description of the above technical solution: four sets of ground stake assemblies are installed inside the two ring plates, and the four sets of ground stake assemblies are arranged in an array inside the two ring plates, and the ground stake assembly includes a ground stake rod.

[0016] By adopting the above technical solution, the ground nail rod is used to limit and support the two ring plates on the ground, thereby achieving the fixed installation of the cover.

[0017] As a further description of the above technical solution: the upper end of the ground spike rod is fixedly connected to a connecting ring, and the ground spike rod passes through two ring plates.

[0018] By adopting the above technical solution, the connecting ring is used to rotate the ground spike rod.

[0019] As a further description of the above technical solution: the ground spike rod is threaded inside the two ring plates, and the lower end of the ground spike rod is conical.

[0020] By adopting the above technical solution, the ground spike rod is rotated and moves down along the ring plate, which then causes the cone-shaped part at the lower end of the ground spike rod to insert into the ground.

[0021] By employing the above technical solution, the protective device for reserved holes in building construction of this utility model has at least the following beneficial effects:

[0022] 1. Compared with existing technologies, this protective device for pre-reserved holes in building construction, by setting up a cover, bushing, lead screw, throttle, connecting plate, sliding rod, fixing sleeve, and four sets of support components, covers the large circular pre-reserved hole opened during foundation construction or pipeline well construction. When the throttle is turned, the lead screw rotates and moves downward along the bushing, causing the connecting plate and sliding rod to move downward during the downward movement of the lead screw. During the downward movement of the connecting plate, the lug on its outer wall moves downward, causing the connecting rod to rotate, thereby pushing the lug and the support plate to move outward. During the outward movement, the ear seat three moves outward and drives the connecting rod two to rotate, thereby achieving the effect of simultaneous outward expansion of the four sets of support components. This allows the four sets of support components to support the inner wall of the large circular reserved hole opened during foundation construction or pipeline wellhead construction. At the same time, the cover is positioned above the large circular reserved hole opened during foundation construction or pipeline wellhead construction, protecting the large circular reserved hole and preventing objects from falling into it, as well as preventing workers from accidentally falling into it.

[0023] 2. Compared with existing technologies, this protective device for pre-reserved holes in building construction is equipped with ring plates, handles, four sets of ground nail rods, and connecting rings. The handles facilitate the handling of the cover, which is then placed over the large circular pre-reserved hole opened during foundation construction or pipeline well construction. The lower surface of one of the ring plates is in contact with the ground. Then, the four sets of ground nail rods are inserted into the ground in sequence. By rotating the connecting rings, the ground nail rods are rotated, causing them to move down along the two ring plates and penetrate through them. The lower conical part of the ground nail rod is inserted into the ground, thereby limiting and fixing the cover above the large circular pre-reserved hole opened during foundation construction or pipeline well construction, thus protecting the large circular pre-reserved hole opened during foundation construction or pipeline well construction.

Two ear seats 3 405 are fixedly connected to the inner wall of support component 4. Connecting rod 2 406 is rotatably connected inside both ear seats 3 405. Ear seat 407 is rotatably connected to the outer wall of both connecting rod 2 406. Connecting rod 2 406 is limited to rotate inside ear seats 3 405 and ear seats 407. Both ear seats 407 are fixedly connected to the outer wall of fixed sleeve 3. A throttle 201 is fixedly connected to the top of screw 2. Slide rod 203 is fixedly connected to both sides of the upper surface of connecting plate 202. Slide rod 203 is slidably connected inside fixed sleeve 3. Slide rod 203 is limited to slide inside fixed sleeve 3.

[0034] Two ear seats 3 405 are set above ear seat 1 402. One ear seat 3 405 is set in the middle of the inner wall of the support plate 401, and the other ear seat 3 405 is set in the upper part of the inner wall of the support plate 401. One ear seat 407 is set in the lower part of the outer wall of the fixing sleeve 3, and the other ear seat 407 is set in the upper part of the outer wall of the fixing sleeve 3. Through the structure of two sets of ear seats 3 405, connecting rod 2 406 and ear seat 407, the support plate 401 is supported, and the support plate 401 is assisted to move outward.

[0035] Two ring plates 103 are fixedly connected to the outer wall of the housing 1. Four sets of handles 104 are fixedly connected to the outer wall of the two ring plates 103. Each set of handles 104 consists of two handles. The four sets of handles 104 are arranged in an array on the outer wall of the two ring plates 103. The four sets of handles 104 can assist in moving the housing 1. Four sets of ground nail assemblies 5 are installed inside the two ring plates 103. The four sets of ground nail assemblies 5 are arranged in an array inside the two ring plates 103. The ground nail assembly 5 includes a ground nail rod 501. A connecting ring 502 is fixedly connected to the upper end of the ground nail rod 501. The ground nail rod 501 passes through the two ring plates 103 and is threaded inside the two ring plates 103. The lower end of the ground nail rod 501 is conical.

[0036] Working principle: When it is necessary to protect a large circular pre-drilled hole during foundation construction or pipeline wellhead construction, the ring plate 103 and the cover 1 are first moved as a whole using four sets of handles 104, so that the cover 1 is placed over the large circular pre-drilled hole during foundation construction or pipeline wellhead construction. The lower surface of one of the ring plates 103 is in contact with the ground, and the four sets of support components 4 are placed inside the large circular pre-drilled hole during foundation construction or pipeline wellhead construction. Then, the handle 201 is rotated to drive the lead screw 2 to rotate, causing the lead screw 2 to move downward along the bushing 101 during rotation. During this process, the connecting plate 202 also moves downward. Simultaneously, the sliding rod 203 moves downward, causing it to slide within the fixed sleeve 3. The downward movement of the connecting plate 202 also moves the four sets of ear seats 404 fixed to its outer wall downward, thereby causing the ends of the four sets of connecting rods 403 connected to the four sets of ear seats 404 to move downward. The connecting rods 403 also rotate, pushing the ear seats 402 and the support plate 401 outward. As the support plate 401 pushes outward, it causes the ear seat 405 to move outward, thus pulling the connecting rod 406 connected to the ear seat 405. One end of the connector moves outward and causes the connecting rod 406 to rotate, achieving the effect of simultaneous outward expansion of the four sets of support plates 401. This allows the four sets of support plates 401 to support the inner wall of the larger circular pre-drilled hole opened during foundation construction or pipeline wellhead construction. During this process, the center of the cover 1 is aligned with the center of the larger circular pre-drilled hole opened during foundation construction or pipeline wellhead construction, and the cover 1 is positioned above the larger circular pre-drilled hole opened during foundation construction or pipeline wellhead construction. Finally, the four sets of ground nail assemblies 5 are taken out, and the four ground nail rods 501 are aligned with the two ring plates 103. Inside the casing, the ground nail rod 501 is rotated by rotating the connecting ring 502, causing the ground nail rod 501 to be threaded into the two ring plates 103 and penetrate through the two ring plates 103. This causes the cone-shaped part at the lower end of the ground nail rod 501 to insert into the ground, thereby limiting and fixing the casing 1 above the large circular reserved hole opened during the foundation construction or pipeline well construction. This protects the large circular reserved hole opened during the foundation construction or pipeline well construction, preventing objects from falling into the reserved hole and also preventing subsequent operators from accidentally falling into the reserved hole, thus improving the safety of building construction.
