Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a protective structure for the edge of an elevator shaft in building construction. Background Technology

[0002] Currently, with the rapid development of the construction industry, residential buildings are getting taller and taller. To facilitate the access of residents, most buildings will install elevators. However, this has brought countless potential safety hazards at the edges and openings, accounting for about 50% of accidents involving falls from heights and being struck by objects. As a result, accidents involving the protection of elevator shaft edges in buildings are frequent, making safe construction a major concern. Safe and civilized construction has also become a window for companies to showcase their image to the outside world.

[0003] Currently, the common practice for protective railings at elevator shaft openings and perimeter openings on construction sites is to use a combination of round steel pipes fixed to the ground and safety nets or horizontal bars. This approach is not conducive to turnover and cannot be reused. The round steel pipes fixed to the ground will obstruct floor construction, requiring frequent removal and installation. Moreover, during the later stages of floor construction, the elevator shaft opening may be unable to be constructed due to the obstruction of the protective door, requiring temporary removal until the floor construction is completed and then reinstalled. Temporary removal does not provide true protection, and dismantling and reinstalling wastes labor and fixing materials, and may even delay the progress of floor construction. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, such as the obstruction caused by protective doors leading to construction difficulties and inconvenience in disassembly and relocation, this utility model proposes a protective structure for the edge of an elevator shaft in building construction.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a protective structure for the edge of a construction elevator shaft, including an outer frame body, an inner frame body rotatably connected to the inner side of the outer frame body, and an installation mechanism provided on the side of the outer frame body.

[0006] The outer frame body has a mounting groove on its side, and the mounting mechanism is set in the mounting groove. The mounting mechanism includes a threaded sleeve rotatably connected to the side wall of the mounting groove. One end of the threaded sleeve is threadedly connected to a stud, and one end of the stud is welded to a pressure block. One end of the pressure block is integrally formed with an insert block, and the end of the insert block penetrates the outer frame body and is integrally formed with a top block. The inner frame body has a limit mechanism on its side.

[0007] Preferably, the outer frame body has a U-shaped structure, and a groove is provided at the bottom of the outer frame body. A rotating bearing is embedded in the groove, and connecting columns are provided on both sides of the inner frame body. The connecting columns are fixedly inserted into the inner ring of the rotating bearing.

[0008] Preferably, the inner frame body has integrally formed retaining strips on both sides, and the upper and lower sides of the retaining strips have integrally formed semi-cylindrical relief portions.

[0009] Preferably, the lower end of the outer frame body is equipped with two sets of symmetrically arranged self-locking casters, and the upper end of the inner frame body is integrally formed with a handle, the outside of which is covered with a rubber sleeve.

[0010] Preferably, the inner frame body has several sets of equidistant hollow vertical railings welded to its inner side, and the vertical railings are welded with reflective warning signs.

[0011] Preferably, a lithium battery is installed at the top center of the inner frame body, warning lights are installed on both sides of the top of the inner frame body, and a marker light strip is installed on the outer side of the inner frame body. Both the warning lights and the marker light strip are electrically connected to the lithium battery.

[0012] Preferably, the inner frame body has an arc-shaped groove at the locking strip, the limiting mechanism is disposed in the arc-shaped groove, and a limiting guide post is inserted into the arc-shaped groove. A tension spring is disposed on the outer side of the limiting guide post, and a pull block is integrally formed at one end of the limiting guide post. The two ends of the tension spring are welded and fixed to the pull block and the arc-shaped groove, respectively, and a corresponding insertion hole is provided on the inner side of the outer frame body.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses an installation mechanism to install the outer frame body together with the inner frame body on the outside of the elevator shaft. The installation mechanism body extends the insert block by rotating the threaded sleeve. Then, the side of the top block will press against the inside of the elevator door, which plays a protective role. It is easy to disassemble and assemble, and will not collapse into the elevator shaft inside the elevator. It is also equipped with self-locking casters and handles, which facilitates movement and turnover, solving the problem of inconvenient disassembly and turnover in the prior art.

[0015] 2. The inner frame body of this utility model is rotatably connected to the outer side of the outer frame body through a rotating bearing, and is fixed by a limiting mechanism set on the side. When it is necessary to enter the elevator shaft for construction, it is only necessary to pull the two pull tabs inward to unlock the limiting guide column and the insertion hole. Then, the inner frame body can be rotated outward using the handle, which solves the problem of construction being impossible due to the obstruction of the protective door.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses an edge protection structure for elevator shaft openings in building construction. (Refer to...) Figure 1 and Figure 2 A protective structure for the edge of a construction elevator shaft includes an outer frame body 1, an inner frame body 2 rotatably connected to the inner side of the outer frame body 1, and an installation mechanism 3 provided on the side of the outer frame body 1.

[0027] The outer frame body 1 has a mounting groove 101 on its side. The mounting mechanism 3 is located in the mounting groove 101. The mounting mechanism 3 includes a threaded sleeve 301 rotatably connected to the side wall of the mounting groove 101. One end of the threaded sleeve 301 is threadedly connected to a stud 302. One end of the stud 302 is welded and fixed to a pressure block 303. One end of the pressure block 303 is integrally formed with an insert 304. The end of the insert 304 penetrates the outer frame body 1 and is integrally formed with a top block 305. The inner frame body 2 has a limit mechanism 4 on its side. The outer wall of the threaded sleeve 301 has anti-slip texture. The inner side has a threaded hole and a stud 302 for threaded connection. The threaded sleeve 301 is rotatably connected to the side wall of the mounting groove 101 through a bearing.

[0028] Reference Figure 4 and Figure 5 The outer frame body 1 has a U-shaped structure, and the bottom of the outer frame body 1 is connected with a groove 102. The groove 102 is fitted with a rotating bearing 103. The inner frame body 2 has connecting columns 201 on both sides. The connecting columns 201 are fixedly inserted into the inner ring of the rotating bearing 103. The inner frame body 2 can be unfolded to any side of the outer frame body 1. After installation, it is easy to temporarily open for construction, which improves the construction efficiency of the elevator shaft.

[0029] Reference Figure 3 and Figure 5 The inner frame body 2 has a retaining strip 202 integrally formed on both sides. The upper and lower sides of the retaining strip 202 are integrally formed with a semi-cylindrical relief part 203. The semi-cylindrical relief part 203 allows the inner frame body 2 to rotate smoothly and prevents the inner frame body 2 from getting stuck and unable to rotate.

[0030] Reference Figure 1 and Figure 4 The lower end of the outer frame body 1 is equipped with two sets of symmetrically arranged self-locking casters 104, and the upper end of the inner frame body 2 is integrally formed with a handle 204. The handle 204 is covered with a rubber sleeve 205. By setting the handle 204 and the self-locking casters 104, it is convenient to transport the outer frame body 1 after it has not been installed on the outside of the elevator shaft or has been removed.

[0031] Reference Figure 1 and Figure 5The inner frame body 2 has several sets of equidistantly distributed hollow vertical railings 206 welded on its inner side. The vertical railings 206 are welded with reflective warning signs 207. The vertical railings 206 can prevent people from falling into the elevator shaft, and the reflective warning signs 207 play a certain warning role.

[0032] Reference Figure 1 and Figure 5 A lithium battery 208 is installed at the top center of the inner frame body 2. Warning lights 209 are installed on both sides of the top of the inner frame body 2. A marker light strip 210 is also installed on the outer side of the inner frame body 2. Both the warning lights 209 and the marker light strip 210 are electrically connected to the lithium battery 208. The warning lights 209 and the marker light strip 210 are connected in parallel and controlled by a switch on the lithium battery 208. The marker light strip 210 can display the outline of the elevator shaft, and the lights inside the warning lights 209 can rotate to warn construction personnel.

[0033] Reference Figure 1 and Figure 3 An arc-shaped groove 211 is provided at the clip 202 of the inner frame body 2. The limiting mechanism 4 is set in the arc-shaped groove 211, and a limiting guide post 401 is inserted into the arc-shaped groove 211. A tension spring 402 is provided on the outside of the limiting guide post 401, and a pull block 403 is integrally formed at one end of the limiting guide post 401. The two ends of the tension spring 402 are welded and fixed to the pull block 403 and the arc-shaped groove 211 respectively. A corresponding insertion hole 105 is provided on the inner side of the outer frame body 1. The outer wall of the pull block 403 is provided with anti-slip texture. When the pull block 403 is pulled inward, the limiting guide post 401 can be released from the range of the insertion hole 105 to unlock. When the limiting guide post 401 is fully inserted into the insertion hole 105 under the action of the tension spring 402, the inner frame body 2 will not shake.

[0034] Working principle: Before installation, the inner frame body 2 and the outer frame body 1 need to be combined to ensure that the limiting guide post 401 is fully inserted into the socket 105 under the action of the tension spring 402. Then, use the handle 204 and the self-locking universal wheel 104 to move the guardrail to the outside of the elevator shaft where it is to be installed, and place the inner wall of the insert block 304 on the outside of the elevator shaft. Then, rotate the threaded sleeve 301 to extend the insert block 304 and press the top block 305 against the inner wall of the elevator shaft for fixation. The firmness of the installation can be checked by shaking the handle 204. Turn on the switch on the lithium battery 208. If the inner frame body 2 needs to be opened for temporary construction, simply pull the pull block 403 inward to release the limiting guide post 401 from the range of the socket 105 to unlock it. Then, pull the inner frame body 2 outward with the handle 204 to enter the shaft for construction.
