Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a cast-in-place protective device for building construction. Background Art

[0002] After the cast-in-place construction of a building is completed, in order to prevent the water inside the cast-in-place concrete from losing too quickly under high temperature, causing holes, cracks and other defects in the cast-in-place concrete that affect the appearance and quality defects, it is necessary to cover the cast-in-place concrete with a film for protection to avoid serious water loss inside the cast-in-place concrete.

[0003] When covering some existing concrete with film, multiple operators are required to cooperate in covering the film on the concrete, so it is troublesome to lay the film. Summary of the invention

[0004] In order to improve the above-mentioned problem that when covering a portion of concrete with a film, multiple operators need to cooperate to cover the film on the concrete, which makes the laying of the film more troublesome, the present application provides a cast-in-place protective device for building construction.

[0005] The present application provides a cast-in-place protective device for building construction, which adopts the following technical solution:

[0006] A cast-in-place protective device for building construction comprises a frame, a film roller is movably inserted into one side of the frame, and a slot is opened at one end of the film roller close to the frame, and a resistance block is slidably connected to the inner wall of the slot, and a spring is arranged on the side surface of the resistance block and the inner wall of the slot, and a hollow rotating rod is rotatably connected to the other side of the frame, and a pulley is fixedly sleeved on the side surface of the hollow rotating rod and the side surface of the wheel at the bottom of the frame, and a transmission belt is arranged between the two pulleys, and an insertion rod is movably inserted into the inner wall of the hollow rotating rod, and the end of the insertion rod close to the frame is in contact with the side surface of the resistance block, the side surface of the frame is fixedly connected to a fixed block, and a pull rod is movably inserted into the side surface of the fixed block, and a retaining ring is fixedly connected to the lower end of the pull rod, and a tension spring is arranged on the side surface of the pull rod and the side surface of the fixed block.

[0007] Through the above technical scheme, the pull rod is pulled upward to cause the retaining ring to move upward, and then the insertion rod is pushed to move and cause it to be plugged into the slot, and then the pull rod is loosened to cause the retaining ring to move downward and block the insertion rod, and then the operator pushes the frame to move and cooperates with the transmission belt to cause the hollow rotating rod to drive the insertion rod to rotate, and at the same time, the film roller is driven by the insertion rod to unwind, so that it is convenient for the operator to lay the film on the surface of the concrete to protect it.

[0008] Optionally, in the above-mentioned cast-in-place protective device for building construction, the film roller and the side surfaces of the hollow rotating rod are fixedly sleeved with bearings, and the side surfaces of the outer rings of the bearings are fixedly connected to the inner walls of the frame.

[0009] The above technical solution can facilitate the use of bearings to increase the stability of the film roller and the hollow rotating rod during rotation.

[0010] Optionally, in the above-mentioned cast-in-place protective device for building construction, one end of the resistance block away from the spring is rounded.

[0011] Through the above technical solution, it is convenient to reduce the friction generated between the hollow rotating rod and the resistance block when the insertion rod is driven to rotate by the rounded corners.

[0012] Optionally, in the above-mentioned cast-in-place protective device for building construction, the inner wall of the slot is shaped like a cross, and the inner wall of the slot is movably connected to the insertion rod.

[0013] Through the above technical scheme, the hollow rotating rod can be rotated by plugging the plug rod into the slot to drive the film roller to rotate together, and then the film roller is unwound to facilitate the operator to cover the film on the concrete surface.

[0014] Optionally, in the above-mentioned cast-in-place protective device for building construction, the shape of the insertion rod is a cross, and one end of the insertion rod away from the resistance block is rotatably connected to a shaft sleeve.

[0015] Through the above technical solution, it is convenient to insert the shaft sleeve into the interior of the retaining ring by moving the insertion rod, thereby reducing the possibility that the shaft sleeve and the insertion rod automatically move and separate from the slot.

[0016] Optionally, in the above-mentioned cast-in-place protective device for building construction, the pull rod is T-shaped, and anti-slip cotton is bonded to the surface of the pull rod.

[0017] Through the above technical solution, the T-shaped pull rod facilitates the operator to pull the pull rod and cause the retaining ring to move, and the anti-skid cotton facilitates increasing the friction force on the pull rod surface to prevent slipping.

[0018] Optionally, in the above-mentioned cast-in-place protective device for building construction, the retaining ring is in the shape of an arc, and the retaining ring is movably sleeved on the side of the insertion rod.

[0019] Through the above technical solution, the position of the insertion rod can be easily limited by the retaining ring, and when the insertion rod is inserted into the slot, the possibility of the insertion rod automatically moving and separating from the slot can be reduced.

[0020] Optionally, in the above-mentioned cast-in-place protection device for building construction, a push rod is fixedly connected to the top surface of the frame.

[0021] Through the above technical solution, it is convenient for the operator to push the frame to move through the push rod.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. By pushing the insertion rod to move and causing it to be plugged into the slot, the operator pushes the frame to move and cooperates with the transmission belt to cause the hollow rotating rod to drive the insertion rod to rotate and cause the film roller to unwind, thereby facilitating the operator to lay the film on the surface of the concrete to protect it, so the film laying is simple and convenient;

[0023] 2. When it is necessary to stop laying the film, pull the pull rod upward to separate the retaining ring from the insertion rod, and then the spring and the resistance block cooperate to push the insertion rod to move and separate it from the slot. At this time, the operator pushes the frame to move and the film roller stops unwinding, so the device is simple and convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 and Figure 3 The present application provides an embodiment: a cast-in-place protective device for building construction, including a frame 1, through which the operator can move the device conveniently, a film roller 2 is movably inserted on one side of the frame 1, and the film roller 2 is unwound to facilitate the operator to cover the film on the concrete, a slot 3 is provided at one end of the film roller 2 close to the frame 1, a resistance block 4 is slidably connected to the inner wall of the slot 3, and a spring 5 is provided between the side of the resistance block 4 and the inner wall of the slot 3.

[0030] A hollow rotating rod 6 is rotatably connected to the other side of the frame 1. Pulleys 7 are fixedly sleeved on the side surfaces of the hollow rotating rod 6 and the side surfaces of the wheels at the bottom of the frame 1. A transmission belt 8 is arranged between the two pulleys 7. The two pulleys 7 cooperate with the transmission belt 8 to cause the hollow rotating rod 6 to rotate when the frame 1 moves. An insertion rod 9 is slidably inserted into the inner wall of the hollow rotating rod 6. The shape of the inner wall of the slot 3 is a cross. The inner wall of the slot 3 is slidably inserted into the insertion rod 9. When the hollow rotating rod 6 rotates through the insertion of the insertion rod 9 into the slot 3, the film roller 2 can be driven to rotate together, and then the film roller 2 is unwound to facilitate the operator to cover the film on the concrete surface.

[0031] The end of the insertion rod 9 close to the frame 1 is in contact with the side of the resistance block 4, and the resistance block 4 cooperates with the spring 5 to facilitate the separation of the insertion rod 9 from the slot 3, thereby prompting the operator to keep the film roller 2 stationary when pushing the frame 1. The shape of the insertion rod 9 is a cross, and the end of the insertion rod 9 away from the resistance block 4 is rotatably connected to the sleeve 15. By moving the insertion rod 9, the sleeve 15 is inserted into the inside of the retaining ring 12, and then the position of the sleeve 15 is limited by the retaining ring 12, thereby reducing the possibility of the sleeve 15 and the insertion rod 9 automatically moving and separating from the slot 3.

[0032] A fixing block 10 is fixedly connected to the side of the frame 1, and a pull rod 11 is movably inserted into the side of the fixing block 10. The pull rod 11 is T-shaped, and anti-skid cotton is bonded to the surface of the pull rod 11. The T-shaped pull rod 11 makes it easy for the operator to pull the pull rod 11 and prompt the retaining ring 12 to move, thereby making it easy for the operator to push the insertion rod 9 to move and prompt it to be inserted into the slot 3, and then the retaining ring 12 is used to limit the position of the insertion rod 9, and the anti-skid cotton is used to increase the friction on the surface of the pull rod 11 to prevent slipping.

[0033] The lower end of the pull rod 11 is fixedly connected with a retaining ring 12, and the side surfaces of the pull rod 11 and the fixed block 10 are provided with tension springs 13. The retaining ring 12 is in the shape of an arc, and the retaining ring 12 is movably sleeved on the side surface of the plug rod 9. The retaining ring 12 is convenient for limiting the position of the plug rod 9. When the plug rod 9 is plugged into the slot 3, the possibility of the plug rod 9 automatically moving and separating from the slot 3 can be reduced. When the plug rod 9 is separated from the plug rod 9, the possibility of the plug rod 9 automatically moving and plugging into the slot 3 can be reduced.

[0034] See the attached drawings in the specification Figure 1 A push rod 16 is fixedly connected to the top surface of the frame 1, and the push rod 16 facilitates the operator to push the frame 1 to move.

[0035] See the attached drawings in the specification Figure 2 and Figure 3 The film roller 2 and the hollow rotating rod 6 are both fixedly sleeved with bearings 14, and the side of the outer ring of the bearing 14 is fixedly connected to the inner wall of the frame 1. The bearing 14 is used to increase the stability of the film roller 2 and the hollow rotating rod 6 during rotation.

[0036] See the attached drawings in the specification Figure 2 and Figure 3 The end of the resistance block 4 away from the spring 5 is rounded, and the rounded corner treatment makes it easier to reduce the friction between the hollow rotating rod 6 and the resistance block 4 when the insertion rod 9 is driven to rotate, thereby reducing the possibility of the insertion rod 9 driving the film roller 2 to rotate again when it is separated from the slot 3.

[0037] Working principle: When using the cast-in-place protective device for house construction, first pull the pull rod 11 upward to move the retaining ring 12 upward, then push the insertion rod 9 to move and plug it into the slot 3, then release the pull rod 11 to move the retaining ring 12 downward and block the insertion rod 9, then the operator pushes the frame 1 to move and cooperates with the transmission belt 8 to drive the hollow rotating rod 6 to drive the insertion rod 9 to rotate, and at the same time, the insertion rod 9 drives the film roller 2 to unwind, so that the operator can lay the film on the surface of the concrete to protect it.

[0038] When it is necessary to stop laying the film, pull the pull rod 11 upward to separate the retaining ring 12 from the sleeve 15 and the insertion rod 9, and then the spring 5 cooperates with the resistance block 4 to push the insertion rod 9 to move and separate from the slot 3. At this time, the operator pushes the frame 1 to move and stops unwinding the film roller 2.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
