Description

Technical Field

[0001] The utility model relates to the technical field of building construction railings, in particular to a spliced ​​building railing. Background Art

[0002] During the construction process, using railings for construction protection is one of the necessary means to improve construction safety. In the process of building construction facilities, all hollow locations of the building need to be installed with guardrails to prevent workers from accidentally entering the hollow locations and falling.

[0003] The existing installation standard for building cavity protection railings is as follows: three steel pipes are arranged vertically in sequence, with an overall height of 1.2 meters. The three steel pipes are fixed to the wall surface using C-shaped clips and expansion bolts to block the cavity.

[0004] During the actual installation operation, it is necessary to determine the installation height of the steel pipe and open the corresponding installation holes on the wall. This operation requires repeated measurement work, which affects the installation efficiency. In order to further improve the installation efficiency of the building cavity protection railing, a spliced ​​building railing is provided. Summary of the Invention

[0005] The purpose of the utility model is to provide a spliced ​​building railing in order to solve the problems in the above background.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a spliced ​​building railing, comprising a mounting assembly for synchronously fixing three steel pipes, the mounting assembly comprising a mounting post, a clamping straight notch, an arc-shaped rail groove, and a fixing hole;

[0007] There are three straight clamping slots, which are distributed vertically on one end surface of the mounting column and are used to provide installation limiting spaces for three steel pipes.

[0008] The fixing holes are symmetrically opened at the upper and lower ends of the end surface of the mounting column and extend through the other end of the mounting column. Expansion bolts are passed through the fixing holes and fixed to the mounting holes on the wall to achieve the installation connection between the mounting column and the wall.

[0009] The arc-shaped rail groove is opened inside the mounting column and distributed outside the clamping straight groove, and the arc-shaped rail groove passes through both sides of the outside of the mounting column;

[0010] The installation column is connected to a limiting component through an arc-shaped rail groove, and the limiting component is used to achieve preliminary limiting of the steel pipe and the installation column.

[0012] The limiting sliding post is symmetrically fixed on both sides of one end of the arc-shaped limiting piece, and the arc-shaped limiting piece is distributed on the inner side of the mounting column and is slidably connected to the arc-shaped rail groove through the limiting sliding post;

[0013] When the limiting slide slides to the lower end position of the arc-shaped rail groove, the arc-shaped limiting piece releases the blockage of the port of the card-connected straight slot. When the limiting slide slides to the upper end position of the arc-shaped rail groove, the arc-shaped limiting piece flips over to achieve the blockage of the port of the card-connected straight slot.

[0014] As a further solution of the present invention: two limiting slides are provided on one side of the arc-shaped limiting plate, the distribution trajectories of the two limiting slides match the arc-shaped rail groove trajectories, and the outer diameter of the limiting slide matches the inner wall width of the arc-shaped rail groove.

[0016] As a further solution of the present invention: the mounting column, the clamping straight notch, the weight-reducing groove, the arc-shaped rail groove, and the fixing hole are integrally formed by an injection molding process.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 5 In an embodiment of the present invention, a spliced ​​building railing includes a mounting assembly 1 for synchronously fixing three steel pipes 3. The mounting assembly 1 includes a mounting column 101, a clamping straight notch 102, an arc-shaped rail groove 104, and a fixing hole 105.

[0027] There are three straight clamping slots 102, which are distributed along the vertical direction and opened on one end surface of the mounting column 101. The three straight clamping slots 102 are used to provide installation limit spaces for the three steel pipes 3.

[0028] The fixing holes 105 are symmetrically arranged at the upper and lower ends of the end surface of the mounting column 101 and extend through the other end of the mounting column 101. Expansion bolts are passed through the fixing holes 105 and fixed to the mounting holes on the wall to achieve the installation connection between the mounting column 101 and the wall.

[0029] The arc-shaped rail groove 104 is formed inside the mounting column 101 and distributed outside the clamping straight slot 102. The arc-shaped rail groove 104 passes through both sides of the outside of the mounting column 101.

[0030] The mounting column 101 is connected to the limiting assembly 2 through the arc-shaped rail groove 104. The limiting assembly 2 is used to achieve the initial limiting of the steel pipe 3 and the mounting column 101.

[0031] The limiting assembly 2 includes an arc-shaped limiting piece 201 and a limiting sliding post 202;

[0032] The limiting slide 202 is symmetrically fixed on both sides of one end of the arc-shaped limiting piece 201. The arc-shaped limiting piece 201 is distributed inside the mounting column 101 and is slidably connected to the arc-shaped rail groove 104 through the limiting slide 202.

[0033] When the limiting slide 202 slides to the lower end position of the arc-shaped rail groove 104, the arc-shaped limiting piece 201 releases the blockage of the end of the card-connected straight slot 102. When the limiting slide 202 slides to the upper end position of the arc-shaped rail groove 104, the arc-shaped limiting piece 201 flips over to achieve the blockage of the end of the card-connected straight slot 102.

[0034] In this embodiment, when the building guardrail is installed to protect the cavity of a building, the operation steps are as follows:

[0035] First, the end face of the mounting column 101 close to the clip-on straight slot 102 can be attached to the surface of the wall at the edge of the cavity, and the height of the uppermost clip-on straight slot 102 can be determined by measuring the ruler, so that the height between the uppermost clip-on straight slot 102 and the floor surface is maintained at 1.2 meters. At this time, the corresponding position of the fixing hole 105 can be marked on the wall. After that, the mounting column 101 can be removed and the mounting hole can be opened at the marked position using a drilling device. Then, the mounting hole can be opened on the edge wall on the other side of the cavity.

[0036] Afterwards, the two mounting posts 101 are placed flat (with their clamping straight slots 102 facing vertically upwards). At this time, the arc-shaped limiting pieces 201 are stored inside the mounting posts 101, and the clamping straight slots 102 are unblocked. Then, the three steel pipes 3 are placed in sequence inside the three groups of clamping straight slots 102, and the arc-shaped limiting pieces 201 are rotated out to seal the openings of the clamping straight slots 102. At this time, the arc-shaped limiting pieces 201 limit the steel pipes 3, thereby completing the preliminary assembly of the steel pipes 3 and the mounting posts 101.

[0037] Finally, the assembled steel pipe 3 and mounting column 101 are flipped over to an upright position and placed close to the wall, with the fixing holes 105 aligned with the pre-opened mounting holes, and then fixed with expansion bolts.

[0038] Through the coordination of the above multiple parts, the three steel pipes 3 can be installed and fixed synchronously, which further simplifies the installation steps, effectively reduces the measurement and positioning operations and the hole-drilling operations, and thus further improves the work efficiency of the cavity protection work in the building.

[0039] Please refer to Figures 1 to 5 Two limiting slides 202 are provided on one side of the arc-shaped limiting piece 201 . The distribution tracks of the two limiting slides 202 match the tracks of the arc-shaped rail groove 104 , and the outer diameter of the limiting slide 202 matches the inner wall width of the arc-shaped rail groove 104 .

[0040] In this embodiment: the structural setting of the two limiting slides 202 enables the arc-shaped limiting piece 201 to maintain a stable arc movement trajectory, and when the arc-shaped limiting piece 201 is rotated out to seal the clamping straight slot 102, it can maintain a stable limit on the steel pipe 3. In this way, in the process of flipping the steel pipe 3 and the mounting column 101 as a whole to the upright state, the steel pipe 3 will not fall off.

[0041] Please refer to Figures 1 to 5 A weight-reducing groove 103 is provided at one end of the mounting post 101 in the middle area between the two fixing holes 105. The weight-reducing groove 103 completely penetrates to the other end of the mounting post 101, and the weight-reducing groove 103 is connected to the three straight slots 102 and the arc-shaped rail groove 104. The arc-shaped limiting piece 201 is distributed on the inner side of the weight-reducing groove 103.

[0042] The mounting column 101 , the clamping straight slot 102 , the weight-reducing slot 103 , the arc-shaped rail slot 104 , and the fixing hole 105 are integrally formed by an injection molding process.

[0043] In this embodiment: the provision of the weight-reducing groove 103 can further reduce the loss of raw materials in the production of the installation column 101, while reducing the weight of the installation column 101, thereby facilitating production cost control and transportation. In addition, the provision of the weight-reducing groove 103 can provide space for the flipping and storage of the arc-shaped limit plate 201.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
