Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a firm masonry structure for the top flat arch of building doors and windows. Background Technique
[0002] Doors and windows are an essential part of a building, playing the roles of lighting, ventilation, and connecting the inside and outside. Building a flat arch or arch on the doors and windows can play a decorative role and also bear the weight of the blue bricks on the arch top. When designing the building, a concrete ear structure is added at this part, and U-shaped bricks are often used as the masonry materials. This structure can effectively fix the upper part of the ear.
[0003] In existing buildings, the lower part of doors and windows is often only bonded with mortar. Affected by the self-weight of the materials and the vibration of door and window opening, with the use of the building, it is easy to occur quality accidents such as insecure masonry, uneven force on the bricks resulting in cracking, and the falling off of the arch bottom. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a firm masonry structure for the top flat arch of building doors and windows, and solves the problems put forward in the above background technique.
[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, it is a firm masonry structure for the top flat arch of building doors and windows, including an outer frame, doors and windows, and connecting ears. A metal plug is penetrated through the bottom end of the outer frame, and the upper surface of the metal plug is aligned with the inner surface of the bottom end of the outer frame. The metal plug includes a left plug and a right plug. A driving groove is opened inside the metal plug, and a rotating long column is arranged inside the driving groove. The rotating long column includes a left long column and a right long column. The top ends of the left long column and the right long column penetrate above the metal plug and are sleeved with knobs.
[0006] Furthermore, through holes are penetrated through both the left and right sides of the metal plug, and a first fixing ring is sleeved inside the driving groove and located on the upper surfaces of the left long column and the right long column.
[0007] Furthermore, threaded grooves are opened on the surfaces of the middle regions of the left long column and the right long column, and a semi-circular block is movably arranged inside the driving groove. The semi-circular block includes a left block and a right block.
[0008] Furthermore, the left block and the right block are centrosymmetric, engaging teeth are opened on the inner surfaces of the left block and the right block, and the left block and the left long column, and the right block and the right long column are rotationally connected through the engaging teeth and the threaded grooves.
[0009] Furthermore, support grooves are provided on the upper surfaces of the left block and the right block, and support shafts are sleeved inside the support grooves, and both ends of the support shafts are fixedly connected to the inner walls of the driving grooves.
[0010] Furthermore, a second fixing ring and a third fixing ring are respectively sleeved on the surface of the support shaft and located on both sides of the semicircular block, and the second fixing ring and the third fixing ring limit the posture of the semicircular block.
[0011] The utility model has the following beneficial effects:
[0012] (1) The utility model adopts the cooperation of the semicircular block, the rotating long column and the threaded groove. After the outer frame is installed inside the wall, it only needs to turn the external knob, and the semicircular block can be driven by the threaded groove to expand and get stuck inside the wall, so that the outer frame can be prevented from falling off due to long-term use of doors and windows.
[0013] (2) The utility model adopts a design of using a thread groove to drive the semicircular block. Once the rotating long column stops rotating, the self-locking property of the thread groove can firmly fix the posture of the semicircular block after it is opened. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.
[0021] As Figures 1-4 shown, according to one aspect of the present utility model, a firm masonry structure for the top flat arch of a building door and window is provided, which includes an outer frame 1, a door and window 2, and a connecting ear 3. A metal insert 4 is penetrated through the bottom end of the outer frame 1, and the upper surface of the metal insert 4 is aligned with the inner surface of the bottom end of the outer frame 1. The metal insert 4 includes a left insert 401 and a right insert 402. A driving groove 6 is formed inside the metal insert 4, and a rotating long column 10 is arranged inside the driving groove 6. The rotating long column 10 includes a left long column 1001 and a right long column 1002. The tops of the left long column 1001 and the right long column 1002 penetrate above the metal insert 4 and are sleeved with a knob 5. After the outer frame 1 is installed inside the wall, just rotate the external knob 5, and the semi-circular block 9 can be driven by the thread groove 11 to expand and be stuck inside the wall, so as to avoid the phenomenon that the outer frame 1 cracks due to the long-term use of the door and window 2.
[0022] In this embodiment, through holes 7 are penetrated through both the left and right sides of the metal insert 4. A first fixing ring 12 is sleeved inside the driving groove 6 and on the upper surfaces of the left long column 1001 and the right long column 1002. The first fixing ring 12 can limit the height of the rotating long column 10 so that it can only rotate and cannot move up and down.
[0023] In this embodiment, thread grooves 11 are formed on the surfaces of the middle regions of the left long column 1001 and the right long column 1002. A semi-circular block 9 is movably arranged inside the driving groove 6. The semi-circular block 9 includes a left block 901 and a right block 902. The vertical height of the through hole 7 is the same as the vertical height of the semi-circular block 9, so as to avoid obstruction when the semi-circular block 9 extends out.
[0024] In this embodiment, the left block 901 and the right block 902 are centrosymmetric. Biting teeth 14 are formed on the inner surfaces of the left block 901 and the right block 902. The left block 901 and the left long column 1001, and the right block 902 and the right long column 1002 are rotationally connected through the biting teeth 14 and the thread grooves 11. The self-locking property of the thread grooves 11 enables the posture of the semi-circular block 9 to be firmly fixed after it expands.
[0025] In this embodiment, support grooves 13 are formed on the upper surfaces of the left block 901 and the right block 902. A support shaft 8 is sleeved inside the support grooves 13, and both ends of the support shaft 8 are fixedly connected to the inner wall of the driving groove 6.
[0026] In this embodiment, a second fixing ring 15 and a third fixing ring 16 are respectively sleeved on the surface of the support shaft 8 and on both sides of the semi-circular block 9, and the second fixing ring 15 and the third fixing ring 16 limit the posture of the semi-circular block 9. The second fixing ring 15 and the third fixing ring 16 can prevent the semi-circular block 9 from shifting inwards or outwards on the support shaft 8.
[0027] The working principle of this device is as follows: After installing the outer frame 1 inside the wall, the metal insert 4 will be embedded inside the wall. Then, simply use a wrench to turn the knob 5, and by rotating the thread groove 11 and the engaging teeth 14 on the long column 10, the semi-circular block 9 can be driven to deflect. The bottom end of the deflected semi-circular block 9 extends through the through-hole 7 and firmly engages inside the wall, so that the metal insert 4 can drive the outer frame 1 to firmly fix structures such as the doors and windows 2 inside the wall.
[0028] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples either. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the essence of the present utility model also fall within the protection scope of the present utility model.
