Description

Technical Field

[0001] This invention belongs to the field of secondary structure construction, and specifically relates to a secondary structure for construction sites and its application method. Background Technology

[0002] Secondary structures on construction sites refer to non-load-bearing masonry, structural columns, lintels, etc., in frame structures, shear wall structures, and frame-shear wall structures. The parts that need to be completed before decoration are called secondary structures. They mainly include infill walls, ring beams, structural columns, drainage ditches, steps, etc. Most existing building structures adopt frame structures. After the frame structure is built, the walls are constructed by masonry blocks.

[0003] In the secondary structural construction of a building, the installation of windows is inevitable. The common installation method is to first reserve the position of the window in the wall, then install the window frame in the reserved opening, and fix it through processes such as glue injection.

[0004] Existing window frames are cumbersome to install and difficult to replace when damaged. With prolonged use, the connection between the window and the track becomes unstable, which can lead to the window falling off and causing safety accidents. Summary of the Invention

[0005] This invention provides a secondary structure for construction sites and its usage method, which solves the technical problems of existing window frames being troublesome to install, difficult to replace when damaged, and prone to falling off due to unstable connection between the window and the sliding track after long-term use, thus causing safety accidents.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a secondary structure for a construction site, comprising a wall with a reserved opening, a fixed frame installed inside the reserved opening, two first frames and two second frames arranged inside the fixed frame, the two opposing first frames and two opposing second frames connected to form a rectangular frame structure that fits against the inner wall of the fixed frame, the first frames being arranged vertically, the second frames being arranged horizontally, the bottom second frame having an upward-facing first sliding groove, the top second frame having a downward-facing second sliding groove, a first slider slidably connected in the first sliding groove, and a second slider slidably connected in the second sliding groove. Two sliders, with the first and second sliding grooves staggered along the thickness of the wall, and two windows between the two second frames. Each window includes a frame and glass. The frames of the two windows are fixedly connected to the first and second sliders, respectively. A limiting groove is provided on the second frame, and a limiting block extending out of the second frame is slidably connected in the limiting groove. A telescopic spring is fixedly connected between the limiting block and the second frame. A fixing hole along the thickness of the wall is provided on the first frame, and a vertical limiting hole is provided on the fixing hole. The limiting block is compressed into the fixing hole by the telescopic spring, and the limiting block is supported into the limiting hole by the telescopic spring.

[0007] By adopting the above technical solution, the integrated window frame structure is changed to an assembled type, which facilitates replacement when the window frame is damaged, saves resources, and the frames can be fixed together by the cooperation between the internal limiting blocks and limiting holes, making it easy to assemble and disassemble.

[0008] Preferably, the window is fixed to the second slider by a first L-connector, and the first L-connector is fixedly connected to the window frame and the second slider by screws.

[0009] By adopting the above technical solution, the sliding mechanism set at the top of the frame uses L-shaped connectors and screws to fix the slider to the window. The second slider limits the window, improving the stability of the window installation and preventing it from falling off due to unstable connection of the slide rail after long-term use.

[0010] Preferably, there are two of each of the first and second slides, which are staggered in the direction of wall thickness.

[0011] By adopting the above technical solution, the window has a better sliding effect and a more stable structure.

[0012] Preferably, the lengths of the first slide and the second slide are each six-tenths of the length of the second frame, and the first slide and the second slide are located at opposite ends of the two second frames.

[0013] By adopting the above technical solution, the length of the chute is reasonable, avoiding excessive length that would reduce the strength of the structure and ensuring the stability of the structure.

[0014] Preferably, the first chute has drainage holes that extend through the first frame along the wall thickness direction, and multiple drainage holes are evenly spaced.

[0015] By adopting the above technical solution, rainwater can be prevented from accumulating inside the groove, thus avoiding leakage in doors and windows.

[0016] Preferably, the top of the limiting block is a sloping structure. When the limiting block is compressed to the bottom by the telescopic spring, the bottom of the sloping structure is flush with the top of the limiting groove. During the shortening process of the telescopic spring, the sloping structure abuts against the second frame.

[0017] By adopting the above technical solution, one of the first frames and one of the second frames are placed in the fixed frame and staggered in the horizontal direction. Then, the first frame is pushed to align the first frame and the second frame. After the inclined structure of the limiting block touches the second frame, it moves downward to compress the telescopic spring until the telescopic spring pushes the limiting block into the limiting hole, thereby fixing the first frame and the second frame.

[0018] Preferably, the bottom of the first slider has a pulley, which is supported at the bottom of the first groove.

[0019] By adopting the above technical solutions, the windows are easier and less strenuous to move, friction is reduced, and service life is increased.

[0020] Preferably, the first frame is fixed to the fixed frame by the second L-connector, and the second L-connector is fixed to the first frame and the fixed frame by bolts respectively.

[0021] By adopting the above technical solution, the first frame and the second frame are fixed and then fixed to the fixed frame by the second L connector, which makes it easy to replace the window frame when it is damaged and saves resources.

[0022] A method for using secondary structures on a construction site includes the following steps. Step 1: A pre-reserved opening is made inside the wall; Step 2: Fix the fixing frame inside the reserved opening; Step 3: Place one of the first frames and one of the second frames in the fixed frame and offset them horizontally. Then push the first frame to align the first frame and the second frame. After the inclined structure of the limiting block touches the second frame, it moves downward to compress the telescopic spring until the telescopic spring pops the limiting block into the limiting hole, thus fixing the first frame and the second frame. Step 4: Install the two first frames and the two second frames in sequence according to Step 3 to form a rectangular frame structure; Step 5: Secure the window to the second frame using the first L-shaped connector; Step 6: Fix the first frame to the fixed frame using the second L-connector to complete the installation; Step 6: When disassembly is required, remove the second L connector, then remove the first and second frames together. Under the action of gravity, the limiting block and the limiting hole will separate, thus allowing the first and second frames to be separated and the replacement completed.

[0023] The beneficial effects of this invention are as follows: 1. The secondary structure of the construction site, by changing the integrated window frame structure to an assembled structure, facilitates replacement when the window frame is damaged, saves resources, and the frames can be automatically fixed together when the inclined surfaces of two frames are attached by utilizing the cooperation between the internal self-locking mechanism and the limiting hole, so as to directly assemble and facilitate installation and disassembly.

[0024] 2. The secondary structure of this construction site uses a sliding mechanism set at the top of the frame to fix the slider to the window with L-shaped connectors and screws. This prevents the slider from falling off due to unstable connection of the slide rail after long-term use. In addition, multiple drainage holes are opened inside the frame to prevent rainwater from accumulating inside the slide groove and causing leakage of doors and windows.

[0025] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention; the main objects and other advantages of the invention may be realized and obtained by means of the embodiments particularly pointed out in the description.

Detailed Implementation

[0028] The technical solutions of the present invention will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and should not be construed as limiting the technical solutions of the present invention.

[0029] Combination Figure 1-4A secondary structure for a construction site includes a wall 1 with a pre-reserved opening. A fixing frame 2 is installed inside the pre-reserved opening. Two first frame bodies 3 and two second frame bodies 4 are arranged inside the fixing frame 2. The two opposing first frame bodies 3 and two opposing second frame bodies 4 are connected to form a rectangular frame structure that fits against the inner wall of the fixing frame 2. The first frame bodies 3 are arranged vertically, and the second frame bodies 4 are arranged horizontally. The bottom second frame body 4 has an upward-facing first sliding groove 5, and the top second frame body 4 has a downward-facing second sliding groove 7. A first slider 6 is slidably connected in the first sliding groove 5, and a second slider 8 is slidably connected in the second sliding groove 7. The first sliding groove 5 and the second sliding groove 7 are within the thickness of the wall 1. The two second frames 4 are staggered and have two windows 17 between them. Each window 17 includes a window frame and glass. The window frames of the two windows 17 are fixedly connected to the first slider 6 and the second slider 8, respectively. The second frame 4 has a limiting groove 11. A limiting block 12 extending out of the second frame 4 is slidably connected in the limiting groove 11. A telescopic spring 13 is fixedly connected between the limiting block 12 and the second frame 4. The first frame 3 has a fixing hole 14 along the thickness direction of the wall 1. The fixing hole 14 has a vertical limiting hole 15. The limiting block 12 is compressed into the fixing hole 14 by the telescopic spring 13 and extended into the limiting hole 15 by the telescopic spring 13.

[0030] By changing the integrated window frame structure to an assembly type, it is easier to replace the window frame when it is damaged, saving resources. The frames can be fixed together by the cooperation between the internal limiting blocks 12 and limiting holes 15, which facilitates direct assembly, making installation and disassembly convenient.

[0031] The window 17 is fixed to the second slider 8 by the first L-shaped connector 9. The first L-shaped connector 9 is fixedly connected to the window frame and the second slider 8 by screws. The slider and the window 17 are fixed together by the sliding mechanism set at the top of the frame using L-shaped connectors and screws. The second slider 8 limits the window 17, improves the stability of the window 17 installation, and prevents the window from falling off due to the unstable connection of the slide rail after long-term use.

[0032] Two first sliding grooves 5 and two second sliding grooves 7 are provided and are staggered in the thickness direction of the wall 1. The sliding effect of the window 17 is good and the structure is relatively stable.

[0033] The lengths of the first slide 5 and the second slide 7 are six-tenths of the length of the second frame 4, respectively. The first slide 5 and the second slide 7 are located at opposite ends of the two second frames 4. The lengths of the slides are reasonable, avoiding excessive length that would reduce the strength of the structure and ensuring the stability of the structure.

[0034] The first chute 5 has drainage holes 10 that extend through the first frame 3 along the thickness of the wall 1. Multiple drainage holes 10 are evenly spaced to prevent rainwater from accumulating inside the chute and causing leakage in doors and windows.

[0035] The top of the limiting block 12 has a sloping structure. When the limiting block 12 is compressed to the bottom by the telescopic spring 13, the bottom of the sloping structure is flush with the top of the limiting groove 11. During the shortening process of the telescopic spring 13, the sloping structure abuts against the second frame 4. One of the first frames 3 and one of the second frames 4 are placed in the fixed frame 2 and staggered in the horizontal direction. Then, the first frame 3 is pushed to align the first frame 3 and the second frame 4. After the sloping structure of the limiting block 12 touches the second frame 4, it moves downward to compress the telescopic spring 13 until the telescopic spring 13 pushes the limiting block 12 into the limiting hole 15, thereby fixing the first frame 3 and the second frame 4.

[0036] The bottom of the first slider 6 has a pulley 16, which is supported at the bottom of the first slide groove 5. This makes the movement of the window 17 more convenient and effortless, reduces friction, and increases its service life.

[0037] The first frame 3 is fixed to the fixed frame 2 by the second L connector 18. The second L connector 18 is fixed to the first frame 3 and the fixed frame 2 by bolts. After the first frame 3 and the second frame 4 are fixed, they are fixed to the fixed frame 2 by the second L connector 18, which makes it easy to replace the window frame when it is damaged and saves resources.

[0038] A method for using secondary structures on a construction site includes the following steps. Step 1: A pre-reserved opening is made inside wall 1; Step 2: Fix the fixing frame 2 inside the reserved opening; Step 3: Place one of the first frame 3 and one of the second frame 4 in the fixed frame 2 and offset them horizontally. Then push the first frame 3 to align the first frame 3 and the second frame 4. After the inclined structure of the limiting block 12 touches the second frame 4, it moves downward to compress the telescopic spring 13 until the telescopic spring 13 pushes the limiting block 12 into the limiting hole 15, thereby fixing the first frame 3 and the second frame 4. Step 4: Install the two first frame bodies 3 and the two second frame bodies 4 in sequence according to Step 3 to form a rectangular frame structure; Step 5: Fix the window 17 to the second frame 4 using the first L connector 9; Step 6: Fix the first frame 3 to the fixed frame 2 using the second L connector 18 to complete the installation; Step 6: When removal is required, remove the second L connector 18, then remove the first frame 3 and the second frame 4 together. Under the action of gravity, the limiting block 12 and the limiting hole 15 will separate, so that the first frame 3 and the second frame 4 can be separated, and the replacement is completed.

Any changes or substitutions that can be conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
