Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a quick-installation edge protection device for building construction. Background Technology

[0002] With the continuous development of construction technology, the requirements for the installation speed, stability, and non-destructive installation of edge protection devices are increasing. To meet these needs, some new edge protection devices have emerged on the market, but most of these devices are complex in structure and cumbersome in operation, making them difficult to widely apply in actual construction.

[0003] Traditional protective devices are mostly installed using welded frames or bolts, which have obvious drawbacks: First, fixed structures cannot adapt to walls of different thicknesses. When encountering irregular building edges or temporary support structures, on-site cutting and modification are often required, resulting in material waste and safety hazards. Second, existing adjustable devices mostly use single-point locking mechanisms, which are prone to slippage in construction environments with frequent vibrations. Therefore, a quick-installable edge protection device for building construction is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a quick-installation edge protection device for building construction, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-installation edge protection device for building construction includes an inner column, two sliding sleeves slidably installed on the outside of the inner column, two sliding grooves fixedly installed on the top and bottom of the inner column, and sliding sliders extending through the four sliding grooves slidably installed inside each of the four sliding grooves. The four sliders are arranged in pairs and symmetrically distributed from left to right. The four sliders are respectively fixedly installed on the top and bottom of the inner walls of the two sliding sleeves. The surfaces of the two sliding sleeves are provided with sliding locking structures that engage with the inner column, and the outer sides of the two sliding sleeves are provided with quick-clamping installation structures.

[0007] The quick-clamping installation structure includes convex plates fixedly installed on the outside of two sliding sleeves. The interior of each of the two convex plates is hollow. A bidirectional screw is rotatably installed inside each of the two convex plates, penetrating to its surface. Two convex plates are threadedly installed on the outside of each of the two bidirectional screws, penetrating to the outside of the convex plates. The convex plates are slidably installed inside the convex plates. Clamping plates are fixedly installed on the outside of each of the four convex plates. Knobs are fixedly installed on the surface of each of the two bidirectional screws.

[0008] The beneficial effects of this utility model are as follows: The protective device uses a slider to install the sliding sleeve on the outside of the inner column and allows it to slide left and right. When in use, the sliding sleeve needs to be pulled open, and the side of the building wall is placed between the clamping plates. Then the sliding sleeve is engaged with the locking structure on the inner column to stabilize the position. At this time, the clamping plates are located on the front and rear sides of the wall. By operating the knob to drive the bidirectional screw to rotate, the clamping plates will move closer to each other and tightly clamp and fix the wall. The whole process realizes the rapid and firm installation of the protective device on the building.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the sliding locking structure includes two grooved plates fixedly installed on the surface of the inner column. The surfaces of the two grooved plates are provided with grooves arranged in a horizontal array. The surfaces of the two sliding sleeves are fixedly installed with a cylindrical frame near their opposite side. The surfaces of the two cylindrical frames are slidably installed with T-shaped rods that penetrate into the interior of the sliding sleeves. The two T-shaped rods are slidably connected to the front wall of the sliding sleeves. The backs of the two T-shaped rods are fixedly installed with inclined blocks that engage with the grooved plates. The exteriors of the two T-shaped rods are fixedly installed with baffle plates. The surfaces of the two baffle plates are fixedly installed with return springs that are fitted onto the exteriors of the T-shaped rods. The two return springs slide inside the two cylindrical frames respectively.

[0011] Furthermore, a supporting convex plate is fixedly installed inside each of the two convex plates, and the two bidirectional screws are respectively rotatably installed inside the two supporting convex plates.

[0012] Furthermore, a handle is fixedly installed on the surface of each of the two sliding sleeves, and the two handles are respectively located near the outer side of the two sleeves.

[0013] Furthermore, the surface of the grooved plate and the surface of the inner column are on the same horizontal plane.

[0014] Furthermore, a rubber plate is fixedly installed on the inner side of the clamping plate. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, such as Figures 1-4 As shown, a quick-installation edge protection device for building construction includes an inner column 1. Two sliding sleeves 2 are slidably installed on the outside of the inner column 1. Two sliding grooves 3 are fixedly installed on the top and bottom of the inner column 1. Sliding sliders 4 that extend through the four sliding grooves 3 are slidably installed inside each of the four sliding grooves 3. The four sliding sliders 4 are arranged in pairs and symmetrically distributed from left to right. The four sliding sliders 4 are fixedly installed on the top and bottom of the inner walls of the two sliding sleeves 2 respectively. The surfaces of the two sliding sleeves 2 are provided with sliding locking structures that engage with the inner column 1. The outer sides of the two sliding sleeves 2 are provided with quick-clamping installation structures.

[0024] Specifically, the quick-clamping installation structure includes convex plates 5 fixedly installed on the outside of the two sliding sleeves 2. The interior of the two convex plates 5 is hollow. A bidirectional screw 6 is rotatably installed inside the two convex plates 5, penetrating to its surface. Two convex plates 7 are threadedly installed on the outside of the two bidirectional screws 6, penetrating to the outside of the convex plates 5. The convex plates 7 are slidably installed inside the convex plates 5. Clamping plates 8 are fixedly installed on the outside of the four convex plates 7. Knobs 9 are fixedly installed on the surface of the two bidirectional screws 6.

[0025] The protective device uses four sliders 4 to mount two sliding sleeves 2 on the outside of the inner column 1, allowing them to slide left and right. In use, the two sliding sleeves 2 need to be pulled outwards first, so that the side walls on both sides of the building are placed between the four clamping plates 8. When the two sliding sleeves 2 are pulled outwards, they engage with the sliding locking structure set on the inner column 1, thus locking the sliding sleeves 2 securely in the external position. At this time, the four clamping plates 8 are located on the front and rear sides of the building wall respectively. Next, by operating the two knobs 9, the two bidirectional screws 6 can be driven to rotate in the forward direction. As the bidirectional screws 6 rotate, the four clamping plates 8 will be forced to move closer to each other until they are tightly clamped and fixed to the side walls of the building. Thus, the protective device can be quickly and firmly installed on the building.

[0026] Example 2, as Figures 4-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] The sliding locking structure includes two grooved plates 10 fixedly installed on the surface of the inner column 1. The surfaces of the two grooved plates 10 are provided with grooves arranged in a horizontal array. The surfaces of the two sliding sleeves 2 are fixedly installed with a cylindrical frame 11 near its opposite side. The surfaces of the two cylindrical frames 11 are slidably installed with T-shaped rods 12 that penetrate into the interior of the sliding sleeves 2. The two T-shaped rods 12 are slidably connected to the front wall of the sliding sleeves 2. The backs of the two T-shaped rods 12 are fixedly installed with inclined blocks 13 that engage with the grooved plates 10. The exteriors of the two T-shaped rods 12 are fixedly installed with baffle plates 14. The surfaces of the two baffle plates 14 are fixedly installed with return springs 15 that are fitted onto the exteriors of the T-shaped rods 12. The two return springs 15 slide inside the two cylindrical frames 11 respectively.

[0028] In this configuration, the device uses two cylindrical supports 11 to constrain the two T-shaped rods 12 to the surfaces of the two sliding sleeves 2, allowing them to slide. When the two return springs 15 are in the extended state, they push the inclined blocks 13 on the back of the two T-shaped rods 12, causing them to enter the grooves on the surfaces of the two grooved plates 10. At this time, the two sliding sleeves 2 are firmly restricted to the outside of the inner column 1. It is worth noting that the inclined surfaces of the two inclined blocks 13 are designed to face outwards. Therefore, when the sliding sleeves 2 move the inclined blocks 13 outwards, the inclined surface design forces the inclined blocks 13 to slide forward along the surface of the grooved plate 10 until they can be engaged in each of the grooves on the grooved plate 10. In this way, the sliding sleeves 2 are further firmly positioned. If it is necessary to release the restriction on the sliding sleeves 2, simply pull the T-shaped rods 12 forward, which will cause the inclined blocks 13 to slide out of the grooves on the surface of the grooved plate 10. In this way, the sliding sleeves 2 are no longer restricted and can be freely slid and adjusted outside the inner column 1.

[0029] Example 3, as Figures 3-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0030] Both convex plates 5 have a support convex plate 16 fixedly installed inside them, and two bidirectional screws 6 are respectively rotatably installed inside the two support convex plates 16.

[0031] With this configuration, the two bidirectional screws 6 are supported by the two supporting convex plates 16 and rotated inside the two convex plates 5 respectively.

[0032] Example 4, as Figure 1 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0033] Handles 17 are fixedly installed on the surfaces of both sliding sleeves 2, and the two handles 17 are respectively close to the outer side of the two cylinder frames 11.

[0034] This design allows for easy control of the two sliding sleeves 2 by holding the two handles 17.

[0035] Example 5, as Figure 3 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0036] The surface of the groove plate 10 is on the same horizontal plane as the surface of the inner column 1.

[0037] This design prevents the sliding sleeve 2 from rubbing against the inner column 1 when it slides outside the inner column 1.

[0038] Example 6, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0039] A rubber plate is fixedly installed on the inner side of the clamping plate 8.

[0040] This design prevents the clamping plate 8 from slipping off the wall.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
