Description

Technical Field

[0001] The present application relates to the field of floor protection structures, and in particular to a building floor protection structure. Background Art

[0002] Building floors are usually cast with reinforced concrete, and there are usually many external corners inside the building. An external corner refers to the corner protruding from the wall surface, such as the four corners protruding from the column and the included angle between the door and window openings and the wall surface.

[0003] In actual building construction operations, the external corners of the building are prone to deformation and damage after being collided. Therefore, corresponding protection equipment is required to protect the external corners during the construction process. The existing external corner protection measures generally fix a wooden board at the external corner and bolt it to the wall to achieve the protection effect.

[0004] Regarding the above related technology, the bolts will damage the wall structure, affect the integrity of the wall, and thus reduce the strength of the building. Summary of the Utility Model

[0005] In order to protect the external corners of the building without damaging the wall structure, the present application provides a building floor protection structure.

[0006] A building floor protection structure provided by the present application adopts the following technical solutions:

[0007] A building floor protection structure includes a plurality of right-angle plates, which are all arranged at the external corner positions of the column. A locking assembly is arranged between adjacent two right-angle plates; the locking assembly includes two locking blocks, which are arranged on the outer sides of the same side of adjacent two right-angle plates. Threaded holes are formed on the opposite sides of the two locking blocks, and a lead screw is threadedly connected between the two locking blocks. The axis of the lead screw is perpendicular to the edge of the column, and opposite threads are respectively arranged at the positions of the lead screw corresponding to the two locking blocks; a holding sleeve is rotatably connected to the central position of the lead screw along its own length direction.

[0008] By adopting the above technical solutions, the worker holds the holding sleeve, ensures that the lead screw is in a horizontal state, abuts the locking assembly and the right-angle plate against the surface of the column together, and rotates the lead screw to make the two locking blocks approach each other, so as to lock the adjacent right-angle plates. This structure effectively protects the external corners of the building without damaging the wall structure by using right-angle plates and a locking assembly. The right-angle plates can abut against the external corner positions, and the locking assembly can tightly connect the right-angle plates to the wall to achieve the protection of the external corners.

[0009] Optionally, the right-angle plates are all arranged at the external corner positions of the hole, and the locking assembly is arranged between the right-angle plates opposite to each other along the length, width, and height directions of the hole.

[0010] By adopting the above technical solution, for the hole, the locking assembly locks the right-angle plate in the three directions of the length, width and height of the hole. The locking assembly pulls the right-angle plate along the width direction of the hole, and pushes and squeezes the right-angle plate along the length and height directions of the hole, so that the right-angle plate is in close contact with the wall.

[0011] For the hole, the two locking blocks approaching or separating from each other can realize the tensioning or butting of the opposite right-angle plates to achieve the protection of the external corner.

[0012] Optionally, a bearing is arranged between the holding sleeve and the lead screw.

[0013] By adopting the above technical solution, the bearing is fixedly connected between the holding sleeve and the lead screw, playing a role in supporting and reducing friction. It enables the lead screw to rotate smoothly, reduces the rotation resistance, and thus facilitates the installation of the protection structure by workers.

[0014] Optionally, a handwheel is coaxially arranged on the lead screw between the two locking blocks.

[0015] By adopting the above technical solution, the handwheel located on one side of the holding sleeve provides a convenient rotating handle, and workers can drive the rotation of the lead screw by rotating the handwheel. The setting of the handwheel makes the rotation operation of the lead screw more flexible and convenient.

[0016] Optionally, two threaded holes are arranged in the locking block, and the two threaded holes are arranged in parallel on one side of the locking block near the diagonal position; the lead screw is arranged along the length, width and height directions of the hole.

[0017] By adopting the above technical solution, the two threaded holes are respectively located on one side of the locking block near the diagonal position, and the staggered setting of the threaded holes ensures the staggered installation of the lead screw in the hole, avoids the interference of the lead screw, and increases the practicability of the device.

[0018] Optionally, the locking block is detachably connected to the right-angle plate.

[0019] By adopting the above technical solution, the locking block is detachably connected to the right-angle plate by bolts. After the building construction is completed and the protection structure is removed, the locking assembly can be recycled for repeated use, saving materials and costs.

[0020] Optionally, a fixing block is arranged on one side of the locking block close to the right-angle plate, a limiting groove matched with the fixing block is opened at the corresponding position of the right-angle plate, and the fixing block can limit the rotation of the locking block in the limiting groove.

[0021] By adopting the above technical solution, the cooperation between the fixing block and the limiting groove enables the fixing block not to rotate during the bolt connection with the right-angle plate, ensuring the stability and reliability of the protection structure.

[0022] Optionally, the end of the threaded hole far from the lead screw is not communicated with the corresponding side wall of the locking block.

[0023] By adopting the above technical solution, the end of the locking block far from the lead screw is not communicated with the threaded hole, ensuring that the lead screw will not penetrate and protrude from the locking block, thus forming an extra part and posing a risk of scratching workers. The safety and reliability of the protection structure are ensured.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By using the right-angle plate and the locking assembly, this structure effectively protects the external corners of a building without damaging the wall structure. The right-angle plate can abut against the external corner position, and the locking assembly can clamp or squeeze the wall with the right-angle plate, achieving the protection of the external corner.

[0026] 2. The components of this structure are highly versatile and applicable to different types of columns and holes. The locking assembly and the right-angle plate can adapt to columns or holes with different edge lengths, and the versatility of all components reduces the production difficulty, improves the production efficiency, and also reduces the production cost of the protection structure.

[0027] 3. A bearing is fixedly connected between the holding sleeve and the lead screw, and a handwheel is also provided on the lead screw. These designs make the operation more convenient and labor-saving. Workers can rotate the handwheel to make the locking blocks approach or move away from each other, thus achieving the protection of the external corner. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0036] The present application embodiment discloses a building floor protection structure. Figure 1 and Figure 2, a building floor protection structure includes a plurality of right-angle plates 3. The plurality of right-angle plates 3 are respectively fixed at the external corners of the column 1 or the hole 2, and all the right-angle plates 3 are arranged horizontally or vertically and aligned. A locking assembly 4 is provided between two adjacent right-angle plates 3 of the column 1. The locking assembly 4 includes two identical locking blocks 41. The locking block 41 is in the shape of a cuboid. One side of the two locking blocks 41 is respectively connected to the outer sides of the same side of the two adjacent right-angle plates 3 by bolts. The bolts pass through the right-angle plate 3 from the inner side of the right-angle plate 3 and are threadedly connected to the locking block 41. A counterbore is provided at the position corresponding to the bolt on the inner side of the right-angle plate 3, and the bolt inside the counterbore will not affect the connection between the right-angle plate 3 and the wall. The detachable connection between the locking block 41 and the right-angle plate 3 ensures that the locking assembly 4 can be reused. Two threaded holes 411 are respectively provided at one end of the two locking blocks 41 facing each other along the length direction of the locking block 41. The two threaded holes 411 are parallel and are located at positions close to the diagonal of the locking block 41. A horizontal lead screw 42 is provided between the two locking blocks 41. The axis of the lead screw 42 is parallel to the length direction of the locking block 41. The lead screw 42 is connected to the two locking blocks 41 through the opposite threaded holes 411. The end of the threaded hole 411 far from the lead screw 42 does not penetrate the locking block 41, ensuring that the lead screw 42 will not penetrate and protrude from the locking block 41 to form an extra part, which poses a risk of scratching workers. Threads with the same shape but opposite directions are respectively provided at both ends of the lead screw 42 corresponding to the two locking blocks 41. The two locking blocks 41 can move closer to and away from each other under the drive of the lead screw 42. A gripping sleeve 421 is rotatably connected to the central position of the lead screw 42 along its own length direction. The worker holds the gripping sleeve 421 by hand to ensure that the lead screw 42 is in a horizontal state, and the locking assembly 4 and the right-angle plate 3 are jointly abutted against the surface of the column 1. By rotating the lead screw 42, the two locking blocks 41 are moved closer to each other, and the adjacent right-angle plates 3 can be locked.

[0037] Referring to Figure 2 , for the hole 2, the difference from the column 1 is that the locking assembly 4 is located between the right-angle plates 3 opposite to each other along the length, width, and height directions of the hole 2. The two misaligned threaded holes 411 ensure the misaligned installation of the lead screw 42 inside the hole 2 and avoid the interference of the lead screw 42. The locking assembly 4 and the right-angle plate 3 are common for the external corner protection of the column 1 and the hole 2, enabling the locking assembly 4 to be reused. At the same time, the universality of all parts reduces the production difficulty, ensures the production efficiency, and reduces the production cost of the protection structure. For the hole 2, by moving the two locking blocks 41 closer to or away from each other, the tension or extrusion of the locking block 41 can be realized, so that the right-angle plate 3 is closely abutted against the wall to achieve the protection of the external corner.

[0038] Referring to Figure 3 and Figure 4, a fixing block 412 is arranged on one side of the locking block 41 close to the right-angle plate 3. A limiting groove 31 adapted to the fixing block 412 is formed in the right-angle plate 3 at a position corresponding to the fixing block 412. The fixing block 412 can limit the self-rotation of the locking block 41 when the locking block 41 is threadedly connected to the right-angle plate 3 within the limiting groove 31. A bearing 422 is fixedly connected between the holding sleeve 421 and the lead screw 42. A hand wheel 423 is coaxially fixedly connected to the lead screw 42 on one side of the holding sleeve 421. The arrangement of the bearing 422 and the hand wheel 423 makes the rotation of the lead screw 42 more convenient and labor-saving. The lead screw 42 is provided with a telescopic portion 424, and the telescopic portion 424 is composed of a sleeve, a telescopic rod and a locking bolt. The locking bolt is threadedly connected to the sleeve and can abut against the telescopic rod, realizing the telescoping and locking of the telescopic portion 424 along the length direction of the lead screw 42. The telescopic portion 424 is not shown in the prior art figure. The length of the lead screw 42 can be changed by the telescoping of the telescopic portion 424, so that the locking assembly 4 can adapt to columns 1 or holes 2 with different edge lengths.

[0039] The implementation principle of a building floor protection structure according to an embodiment of the present application is as follows: Connect the right-angle plate 3 and the locking block 41 with bolts, adjust the length of the telescopic portion 424 of the lead screw 42 so that the distance between the two right-angle plates 3 is slightly greater than the distance between two adjacent or opposite external corners. Hold the holding sleeve 421 and place the right-angle plate 3 at the position of the external corner to be protected, so that the right-angle plate 3 abuts against the external corner. Hold the holding sleeve 421 and fix the locking assembly to prevent the locking assembly from shifting during the rotation of the lead screw 42. Then rotate the hand wheel 423 to make the locking blocks 41 approach or move away from each other, so that the right-angle plates 3 clamp or squeeze the wall against each other to achieve the purpose of protection. Operate each locking assembly 4 in sequence to realize the locking of the entire protection structure and achieve the protection purpose.

[0040] The embodiment of the present application has the effect of protecting the external corners of a building without damaging the wall structure.

[0041] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
