Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a positioning and protection device for vertical laying holes between floors. Background Technology

[0002] During the construction of the main structure of high-rise buildings, vertical projection of axes and control points is required through vertical layout holes between floors to ensure the accuracy of construction layout on each floor. Layout holes are usually square or round openings pre-reserved in the floor slabs of each floor.

[0003] The existing main structure adopts a frame shear wall structure. During the construction of each concrete floor slab, the axis measurement between floors is carried out in a traditional way. This has disadvantages such as the difficulty in verifying the axis measurement of newly poured floors and the frequent lack of protection for the floor slab layout holes. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a positioning and protection device for vertical cable laying holes between floors. A fixed bracket is placed directly above the cable laying hole on the floor slab, allowing the positioning dotted cloth to cover the hole. Self-tapping screws are used to fix the bracket to the floor slab. This device is lightweight, convenient, easy to install and dismantle, and can greatly save manpower and resources. It is highly efficient, convenient, and reusable, demonstrating excellent on-site performance and significantly improving project quality. It possesses high economic benefits and is worthy of widespread promotion.

[0005] The technical solution to achieve the purpose of this invention is: a positioning protection device for vertical cable laying holes between floors, including a fixed bracket, a positioning dot cloth fixedly connected to the fixed bracket, a protective cover plate rotatably connected to the fixed bracket, and diagonal markings on the positioning dot cloth.

[0006] In some embodiments, multiple iron plates are fixedly connected to the fixed bracket, and each of the iron plates is provided with self-tapping screws.

[0007] In some embodiments, the bottom of the fixing bracket is attached to a floor slab, and a wire-laying hole is provided on the floor slab, with the fixing bracket located directly above the wire-laying hole.

[0008] In some embodiments, two bidirectional threaded rods are rotatably connected to the fixed bracket, and two clamps are screwed onto each of the two bidirectional threaded rods. A transmission wheel is fixedly connected to each of the two bidirectional threaded rods, and a transmission belt is tensioned and sleeved on both transmission wheels.

[0009] In some embodiments, one end of one of the bidirectional threaded rods is fixedly connected to a knob.

[0010] In some embodiments, the inner wall of the fixed bracket is fixedly connected to two slide rails, and two sliders are slidably connected to each of the two slide rails. One end of each of the four sliders is fixedly connected to one of the four clamps.

[0011] In some embodiments, each of the four clamping plates is slidably connected with a protruding nail block, and each of the four clamping plates is provided with a compression spring, the two ends of which are fixedly connected to the clamping plate and the protruding nail block, respectively.

[0012] In some embodiments, each of the four sliders is fixedly connected to a fixing rod, and the inner wall of the fixing bracket is fixedly connected to four rubber sleeves.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] Firstly, this invention places the fixed bracket directly above the wire-laying hole in the floor slab, so that the positioning and casting cloth covers the wire-laying hole, and fixes it to the floor slab with self-tapping screws to fix the fixed bracket. This device is lightweight, convenient, easy to install and dismantle, and can greatly save manpower and material resources. It is efficient, convenient, and reusable. It has good on-site performance and can greatly improve the quality of the project. It has extremely high economic benefits and is worth promoting.

[0015] Secondly, this invention utilizes a combination of bidirectional threaded rods, clamping plates, a transmission belt, and a knob. Rotating the knob drives the two bidirectional threaded rods to rotate synchronously, thereby causing the four clamping plates to move in opposite directions or in opposite directions along the slide rail. This allows the protruding nail blocks on the clamping plates to tightly press against the wall of the wire-laying hole, achieving a quick and stable connection between the device and the floor slab. This effectively prevents the device from shifting during construction and ensures the continuous accuracy of the measurement points. At the same time, the protruding nail blocks, under the action of the compression spring, can adapt to the unevenness of the hole wall, enhancing the reliability of the clamping.

[0016] Thirdly, the invention, through the setting of the fixing rod and the rubber sleeve, creates a large frictional force between the rubber sleeve and the fixing rod, effectively preventing the bidirectional threaded rod from loosening and improving the fixing effect of the fixed bracket.

[0017] This solves the existing problems of high difficulty in verifying the axis of newly poured floors and frequent lack of protection for floor slab layout holes. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides an improved positioning and protection device for vertical cable laying holes between floors. The technical solution of this invention is as follows:

[0029] Example 1:

[0030] like Figures 1-3As shown, a positioning and protection device for vertical cable laying holes between floors includes a fixed bracket 1, a positioning dotted cloth 11 fixedly connected to the fixed bracket 1, a protective cover plate 13 rotatably connected to the fixed bracket 1, diagonal markings 12 on the positioning dotted cloth 11, and multiple iron plates 14 fixedly connected to the fixed bracket 1, each iron plate 14 having a self-tapping screw 15. The bottom of the fixed bracket 1 is attached to a floor slab 2, and a cable laying hole 21 is opened on the floor slab 2. The fixed bracket 1 is located directly above the cable laying hole 21. By setting the fixed bracket 1, the fixed bracket 1 is placed directly above the cable laying hole 21 on the floor slab 2, so that the positioning dotted cloth 11 covers the cable laying hole 21. It is fixed to the floor slab 2 with self-tapping screws 15, thus fixing the fixed bracket 1. This device is lightweight, convenient, easy to install and dismantle, can greatly save manpower and material resources, is efficient and convenient to operate, reusable, and has good on-site performance. It can greatly improve the quality of the project and has high economic benefits, making it worthy of promotion. The positioning dotted cloth 11 is made of transparent nylon cloth.

[0031] Example 2:

[0032] like Figures 4-6 As shown, in one embodiment, two bidirectional threaded rods 3 are rotatably connected to the fixed bracket 1. Two clamping plates 31 are screwed onto each of the two bidirectional threaded rods 3. A transmission wheel 32 is fixedly connected to each of the two bidirectional threaded rods 3. A transmission belt 33 is tensioned and sleeved on both transmission wheels 32. A knob 38 is fixedly connected to one end of one of the bidirectional threaded rods 3. By setting the clamping plates 31, the operator can manually rotate the knob 38 to drive one of the bidirectional threaded rods 3 to rotate. The transmission wheel 32 and the transmission belt 33 drive the other bidirectional threaded rod 3 to rotate synchronously. The rotation of the two bidirectional threaded rods 3 drives the four clamping plates 31 on them to move towards the wall of the wire feeding hole 21 until the clamping plates 31 are in close contact with the inner wall of the wire feeding hole 21, which facilitates the fixing of the fixed bracket 1.

[0033] like Figure 5 As shown, in one embodiment, two slide rails 34 are fixedly connected to the inner wall of the fixed bracket 1, and two sliders 35 are slidably connected to each of the two slide rails 34. One end of each of the four sliders 35 is fixedly connected to one of the four clamping plates 31. Through the arrangement of the slide rails 34, the cooperation between the slide rails 34 and the sliders 35 enables the clamping plates 31 to be guided, ensuring that the clamping action is stable.

[0034] like Figure 6 As shown, in one embodiment, each of the four clamping plates 31 is slidably connected with a protruding nail block 36, and each of the four clamping plates 31 is provided with a compression spring 37. The two ends of the compression spring 37 are fixedly connected to the clamping plate 31 and the protruding nail block 36, respectively. With the setting of the protruding nail block 36, the protruding nail block 36 is tightly pressed against the hole wall under the elastic force of the compression spring 37, so that the entire device is firmly locked in the wire feeding hole 21, which plays a role in preventing slippage.

[0035] like Figure 5 As shown, in one embodiment, each of the four sliders 35 is fixedly connected to a fixing rod 4, and the inner wall of the fixing bracket 1 is fixedly connected to four rubber sleeves 41. With the setting of the fixing rods 4, the movement of the clamping plate 31 drives the sliders 35 to move, and the movement of the sliders 35 drives the fixing rods 4 to enter the rubber sleeves 41, so that there is a large friction between the rubber sleeves 41 and the fixing rods 4, which effectively prevents the bidirectional threaded rods 3 from loosening and improves the fixing effect of the fixing bracket 1.

[0036] The specific working method is as follows: the fixed bracket 1 is placed directly above the wire hole 21 of the floor slab 2, so that the positioning and casting cloth 11 covers the wire hole 21, and the fixed bracket 1 is fixed on the floor slab 2 with self-tapping screws 15. This device is lightweight, convenient, easy to install and dismantle, can greatly save manpower and material resources, is efficient and convenient to operate, can be reused, has good on-site use effect, can greatly improve the quality of the project, and has extremely high economic benefits and is worth promoting.

[0037] The operator manually rotates knob 38 to drive one of the bidirectional threaded rods 3 to rotate. This rotation, via transmission wheel 32 and transmission belt 33, drives the other bidirectional threaded rod 3 to rotate synchronously. The rotation of the two bidirectional threaded rods 3 drives the four clamping plates 31 on them to move along slide rail 34 toward the wall of the wire feeding hole 21 until the clamping plates 31 are in close contact with the inner wall of the wire feeding hole 21. At the same time, the protruding nail block 36 is tightly pressed against the hole wall under the elastic force of the compression spring 37, thus firmly locking the entire device into the wire feeding hole 21, facilitating the fixation of the fixed bracket 1. The movement of the clamping plates 31 drives the slider 35 to move, and the movement of the slider 35 drives the fixed rod 4 into the rubber sleeve 41, resulting in greater friction between the rubber sleeve 41 and the fixed rod 4, effectively preventing the bidirectional threaded rod 3 from loosening and improving the fixation effect of the fixed bracket 1.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
