Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a spliced ​​steel structure guardrail for engineering construction. Background Art

[0002] Guardrails usually refer to a kind of fence or railing used for protection or isolation. They are used for edge protection, safety protection or restricting access. In municipal engineering, when construction operations are carried out in a certain area, in order to prevent dangerous situations such as high-altitude objects from affecting the lives and safety of passers-by, guardrails are usually set up to isolate the construction area.

[0003] However, in the prior art, guardrails are usually fixed by bolts, which is very cumbersome. At the same time, the use of bolts will increase the cost of accessories, and it will take a lot of time to install and disassemble, which is very inconvenient. Therefore, it is necessary to propose a new type of spliced ​​steel structure guardrail for engineering construction. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the prior art, guardrails are usually fixed by bolts, which is very cumbersome to operate. At the same time, the use of bolts will also increase the cost of accessories, and it takes a lot of time to install and disassemble, which is very inconvenient. The problems raised in the background technology are solved by providing an embedded snap-on splicing adaptation method.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spliced ​​steel structure guardrail for engineering construction, comprising: two guardrail posts, two extension blocks are welded on both sides of the outer walls of the two guardrail posts, the outer walls of the eight extension blocks are provided with slots, the outer walls of the two guardrail posts are provided with two grooves on both sides of the outer walls, the inner walls of the eight grooves are movably inserted with fixed shells, a connecting mechanism is provided between the opposite sides of the two guardrail posts, the outer walls of the eight extension blocks are fixedly installed with fixed blocks on both sides, and the outer walls of the eight fixed shells are provided with fixed grooves on both sides;

[0006] The connecting mechanism includes two connecting shells, both sides of the inner walls of the two connecting shells are movably inserted with connecting columns, the outer walls of the four connecting columns are fixedly installed with buckles, and the outer walls of the four buckles are movably inserted into the inner walls of four of the eight slots.

[0007] Preferably, the outer walls of the two connecting shells are each provided with two slots, the outer walls of the four connecting columns are each provided with a group of stabilizing grooves, the inner walls of two of the four slots are movably inserted with fixing columns, and the outer walls of the two fixing columns are movably inserted in the inner walls of the other two of the four slots, and the outer walls of the four fixing columns are movably inserted in the inner walls of four of the four groups of stabilizing grooves; when it is necessary to fix the connecting mechanism of the telescopic structure, the fixing columns can be inserted into the slots and the stabilizing grooves to prevent the connecting columns from slipping in the connecting shell.

[0008] Preferably, a rotating shaft is movably inserted into the inner wall of the two fixed columns, and a threaded rod is fixedly installed at the bottom end of the two rotating shafts. A support seat is rotatably sleeved on the outer wall of the two threaded rods, so that after the connecting shell and the connecting column are fixed, the fixed column can be fixed through the support seat.

[0009] Preferably, the top ends of the two rotating shafts are fixedly sleeved with knobs, so that when the threaded rod and the rotating shaft need to be rotated, the knobs can be held and rotated, making it easier to rotate the threaded rod and fixing the threaded rod to the support seat.

[0010] Preferably, both sides of the outer walls of the eight extension blocks are provided with sliding grooves, both sides of the inner walls of the eight fixed shells are fixedly installed with sliders, and the outer wall of each slider is movably inserted into the inner wall of each sliding groove, so that when the fixed shell needs to be moved, the fixed shell can be limited to prevent the fixed shell from falling.

[0011] Preferably, a shift block is fixedly mounted on the top of each of the eight fixed shells, so that when the fixed shell needs to be moved, the shift block can be held to make the fixed shell easier to move.

[0012] Preferably, decorative panels are fixedly mounted on the front surfaces of the two guardrail posts, wherein warning slogans such as "Do not approach" can be written on the decorative panels, so that pedestrians can stay away on their own to prevent being hit by foreign objects.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, by arranging a card slot on the guardrail column and a card block on the connecting mechanism, the two guardrail columns are connected by two connecting mechanisms by means of the card block being buckled into the card slot. The connecting mechanism here adopts a telescopic structure, and the length of the connecting mechanism can be freely adjusted, which makes transportation more convenient. At the same time, the steel structure parts are connected to form a guardrail by means of embedded card buckle splicing and adaptation, which not only ensures the rigid strength requirements of the connection, but also avoids the cumbersome operation process of bolt locking and fixing in the prior art, thereby improving efficiency and reducing the cost of accessories.

[0015] 2. In the utility model, slots and fixed columns are provided. Since the connecting mechanism adopts a telescopic mechanism, in daily work, once the guardrail column is displaced due to the impact force, the structure between the guardrail columns is very likely to fail to achieve a stable effect due to the instability of the telescopic structure. When the two guardrail columns need to be more stable, the position of the lower guardrail column can be moved so that the corresponding stable groove and slot can overlap. In this way, the fixed column can be inserted into the stable groove and fixed to the support seat, thereby improving the stability between the two guardrail columns.
