Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for controlling the thickness and spacing of the protective layer of side wall reinforcement. Background Technology

[0002] The thickness of the concrete cover refers to the distance between the small layer of concrete on top of the concrete. The concrete cover is the part of the concrete that protects the reinforcing bars from direct exposure. It is the minimum distance from the concrete surface to the outer edge of the nominal diameter of the outermost reinforcing bar. The spacing refers to the distance between the reinforcing bars. Therefore, spacing control equipment is needed during construction.

[0003] The existing control equipment first moves the pull rod to the corresponding position, extends the extension line to set the thickness of the concrete protective layer, then passes through the marking rod to mark the spacing of the rebar rows before construction can proceed. However, the marking rod needs to be marked along one direction of the wall, which means that the operator needs to re-level the wall after moving the marking rod.

[0004] The aforementioned control equipment requires operators to re-level the line after moving the marking pole, which consumes a lot of time and reduces the effectiveness of the device. Utility Model Content

[0005] This utility model proposes a device for controlling the thickness and spacing of the protective layer of side wall reinforcement bars, in order to solve the problem that it is difficult to keep the line marking rod horizontal during the movement of the existing technology.

[0006] The technical solution of this utility model is as follows: A device for controlling the thickness and spacing of the protective layer of side wall reinforcement, including a support column, and further comprising:

[0007] The connecting frame is installed on the upper surface of the support column. A first buffer spring is installed inside the connecting frame, and a movable column is installed at the inner end of the first buffer spring. A second buffer spring is installed inside the connecting frame, and an auxiliary rod is installed at the inner end of the second buffer spring. The auxiliary rod and the movable column are both located inside the connecting frame. The movable frame is slidably connected to the outer side of the connecting frame. A fixing plate is installed on the outer side of the movable frame. A movable rod passes through the inside of the fixing plate. A connecting pin passes through the outer side of the fixing plate. One end of the connecting pin, which passes through the fixing plate, abuts against the movable rod. The connecting plate is installed on the outer side of the movable frame. A connecting frame is rotatably connected inside the connecting plate. A retaining frame is installed on the inner side of the connecting frame.

[0008] As a preferred embodiment of the device for controlling the thickness and spacing of the protective layer of the side wall reinforcement described in this utility model, in order to facilitate the operator to draw lines on the wall, an installation plate is installed at the bottom of the moving rod, and a drawing pen is inserted through the interior of the installation plate.

[0009] As a preferred embodiment of the device for controlling the thickness and spacing of the protective layer of the side wall reinforcement described in this utility model, in order to prevent the fixing frame from becoming loose, the outer side of the support column is slidably connected to the fixing frame, the outer side of the fixing frame is provided with a fixing pin, and one end of the fixing pin inserted into the fixing frame abuts against the support column.

[0010] As a preferred embodiment of the device for controlling the thickness and spacing of the protective layer of the side wall reinforcement described in this utility model, in order to better adjust the thickness of the protective layer, a support rod is installed on the back of the fixing frame, a contact piece is installed at the rear end of the support rod, and an auxiliary plate is provided on the outer surface of the support rod.

[0011] As a preferred embodiment of the device for controlling the thickness and spacing of the protective layer of the side wall reinforcement described in this utility model, in order to prevent the protective layer from being too far behind, a laser light is installed on the front of the auxiliary plate, an installation tube is installed on the front of the auxiliary plate, and the outer surface of the support rod penetrates through the interior of the installation tube.

[0012] As a preferred embodiment of the device for controlling the thickness and spacing of the protective layer of the side wall reinforcement described in this utility model, in order to better adjust the auxiliary plate, a plug pin is provided on the outer surface of the mounting pipe, and one end of the plug pin inserted into the mounting pipe abuts against the support rod.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, by manipulating the connecting frame to flip outward along the connecting piece, the card frame flips outward and fits onto the outer surface of the auxiliary rod. Compared with the prior art of directly moving the marking rod and then leveling, this device can limit the movement range of the moving frame, which can prevent the operator from having to readjust the leveling process when adjusting the marking pen.

[0015] In this invention, by manipulating the connecting frame to move outward, the auxiliary rod extends through the second buffer spring, allowing the locking frame to lock onto the surface of the auxiliary rod. Compared to the prior art where the leveling is re-established after adjusting the marking rod, this device can expand the range of movement while keeping the horizontal direction of the moving frame unchanged, thus improving the effectiveness of the device.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this embodiment proposes a device for controlling the thickness and spacing of the protective layer of side wall reinforcement, including a support column 1, a connecting frame 2, a first buffer spring 3, a movable column 4, a second buffer spring 5, an auxiliary rod 6, a movable frame 7, a fixing plate 8, a movable rod 9, a connecting pin 10, a connecting plate 11, a connecting frame 12, and a clamping frame 13.

[0024] like Figure 3 As shown, the connecting frame 2 is installed on the upper surface of the support column 1. A first buffer spring 3 is installed inside the connecting frame 2, and a moving column 4 is installed at the inner end of the first buffer spring 3. A second buffer spring 5 is installed inside the connecting frame 2, and an auxiliary rod 6 is installed at the inner end of the second buffer spring 5. Both the first buffer spring 3 and the second buffer spring 5 are initially compressed. During the outward movement of the connecting frame 2, the first buffer spring 3 and the second buffer spring 5 rebound, pushing the moving column 4 and the auxiliary rod 6 out of the connecting frame 2, respectively. Both the auxiliary rod 6 and the moving column 4 are located inside the connecting frame 2. Figure 4As shown, the movable frame 7 is slidably connected to the outer side of the connecting frame 2. A fixing plate 8 is installed on the outer side of the movable frame 7. A movable rod 9 passes through the inside of the fixing plate 8. A connecting pin 10 passes through the outer side of the fixing plate 8. One end of the connecting pin 10, which passes through the fixing plate 8, abuts against the movable rod 9. An installation plate 14 is installed at the bottom of the movable rod 9. A marking pen 15 passes through the inside of the installation plate 14. The marking pen 15 consists of a marking rod and a pen tip. The pen tip is the common chalk on the market. A connecting plate 11 is installed on the outer side of the movable frame 7. A connecting frame 12 is rotatably connected inside the connecting plate 11. A clip frame 13 is installed on the inner side of the connecting frame 12. The clip frame 13 is a common plastic tube clip on the market. It should be noted that after the clip frame 13 is fitted onto the surface of the auxiliary rod 6, the movable frame 7 can move to the left and right sides through the clip frame 13. The connecting frame 12 is an L-shaped frame, so there will be no shaking during the movement of the movable frame 7.

[0025] like Figure 2 As shown, a fixed frame 16 is slidably connected to the outer side of the support column 1. A fixing pin 17 is inserted through the outer side of the fixed frame 16. One end of the fixing pin 17, which is inserted into the fixed frame 16, abuts against the support column 1. A support rod 18 is installed on the back of the fixed frame 16. A contact piece 19, made of rubber, is installed at the rear end of the support rod 18. An auxiliary plate 20 is provided on the outer surface of the support rod 18. A laser lamp 21 is installed on the front of the auxiliary plate 20. The laser lamp 21 is a common laser irradiation lamp on the market. After the auxiliary plate 20 is moved, the laser lamp 21 is turned on to irradiate the horizontal position of the wall. It should be noted that the laser lamp 21 can irradiate laser lines after being powered on. When the protective layer is thick, the light emitted by the laser lamp 21 is blocked by the protective layer. An installation tube 22 is installed on the front of the auxiliary plate 20. The outer surface of the support rod 18 passes through the interior of the installation tube 22. A plug pin 23 is inserted through the outer surface of the installation tube 22. One end of the plug pin 23, which is inserted into the installation tube 22, abuts against the support rod 18.

[0026] In this embodiment, as Figure 1 As shown, a support plate 24 is installed on the lower surface of the support column 1, and a counterweight 25 is provided on the upper surface of the support plate 24. It should be noted that after the support plate 24 is adjusted, the counterweight 25 is needed to press it down.

[0027] In this embodiment, the device is moved to its placement location. The connecting frame 2 is moved outwards, causing the support column 1 to move outwards. The support column 1 moves outwards, causing the support plate 24 to move outwards, resulting in the first buffer spring 3 and the second buffer spring 5 rebounding. This causes the moving column 4 and the auxiliary rod 6 to extend outwards from the connecting frame 2, allowing the support column 1 to move to the left and right sides of the wall. The counterweight 25 is placed on the upper surface of the support plate 24. The connecting frame 12 is then rotated outwards along the connecting piece 11. This rotation causes the locking frame 13 to rotate outwards, allowing it to fit over the outer surface of the auxiliary rod 6. The marking pen 15 is then inserted into the mounting plate 14. Pull out the connecting pin 10, manipulate the moving rod 9 to move upward along the fixed plate 8, the moving rod 9 moves upward and drives the mounting plate 14 to move upward, the mounting plate 14 moves upward and drives the marking pen 15 to move upward, draw lines on the wall, install the steel reinforcement frame at the drawn line, manipulate the moving frame 7 to move to the right and drive the connecting plate 11 to move to the right, the connecting plate 11 moves to the right and drives the connecting frame 12 to move to the right, the connecting frame 12 moves to the right and drives the clamping frame 13 to move to the right, so that the clamping frame 13 moves along the surface of the auxiliary rod 6, draw lines on the fixed position of the next set of steel reinforcement frames, after the drawing is completed, pull the marking pen 15 out of the mounting plate 14;

[0028] Manipulate the fixed frame 16 to move upward along the support column 1. The upward movement of the fixed frame 16 drives the support rod 18 to move upward, which in turn drives the auxiliary plate 20 to move upward. After the movement is complete, manipulate the fixed pin 17 to pass through the fixed frame 16 and press against the support column 1. Pull out the plug pin 23. Manipulate the auxiliary plate 20 to move backward, which drives the laser light 21 to move backward, so that the mounting tube 22 moves along the surface of the support rod 18. After the adjustment is complete, manipulate the plug pin 23 to pass through the mounting tube 22 and press against the support rod 18. Turn on the laser light 21 to monitor and control the thickness of the protective layer.

[0029] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
