[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a prefabricated guardrail for prefabricated steel structure buildings includes an installation platform 1. A base 101 is fixedly connected to the bottom of the installation platform 1, and the base 101 is fixedly connected to the steel structure building to secure the guardrail. Two sets of fixing slots 102 are fixedly provided at the lower part of the installation platform 1. The fixing slots 102 have rounded corners to facilitate the insertion of guardrail 1 (2) and guardrail 2 (3) into the fixing slots 102. By setting up the installation platform 1, guardrail 1 (2), and guardrail 2 (3), the width of the guardrail and the angle between the guardrail and the installation platform 1 can be adjusted arbitrarily according to the site conditions, and multiple sets of guardrails can be spliced and fixed to complete the enclosure work for the steel structure building.
[0032] The bottom of the fixed socket 102 is fixedly provided with a groove ring 102A, and the top of the fixed socket 102 is fixedly provided with a sliding groove 103. A lock head 4 is slidably connected in the sliding groove 103. By setting the lock head 4, when the user lifts the lock head 4 upwards, the guardrail can be installed and the distance between guardrail 1 2 and guardrail 2 3 can be adjusted, and the installation angle between the guardrail and the mounting platform 1 can be changed. Thus, the guardrail can be adjusted according to the actual conditions of the steel structure building. Pressing down the lock head 4 can lock the distance between guardrail 1 2 and guardrail 2 3 and lock the posture of the guardrail relative to the mounting platform 1, so as to realize the enclosure operation of the guardrail.
[0033] Multiple sets of limiting grooves 103A are fixedly provided on the lower inner wall of the slide 103. A retaining ring 103B is fixedly connected to the upper inner wall of the slide 103. A guardrail 2 is rotatably connected to the left fixed socket 102 of the mounting platform 1. The guardrail 2 has a locking component 6 inside. By setting the locking component 6, the pressing slider 605 is pushed outward to press the inner wall of the crossbar 302, thereby locking the width between the guardrail 2 and the guardrail 3. The locking post 604 is pushed outward to insert into the groove ring 102A, thereby axially fixing the guardrail 2 and the mounting platform 1. A guardrail 3 is rotatably connected to the right fixed socket 102 of the mounting platform 1. Figure 13 As shown, guardrail 2 3 includes vertical bar 2 301, with a circumferential groove 2 301A fixedly opened at the top of vertical bar 2 301, and multiple sets of horizontal bars 2 302 fixedly connected to the side wall of vertical bar 2 301. Guardrail 2 3 cooperates with guardrail 1 2, by inserting the horizontal bar 1 202 of guardrail 1 2 into the inner wall of the horizontal bar 2 302 of guardrail 2 3 to complete the assembly of the two, and after inserting it into the mounting platform 1, the enclosure operation can be realized to protect the workers.
[0034] like Figure 4 and Figure 5 As shown, a pull ball 403 is fixedly connected to the top of the lock head 4. The user can lift the lock head 4 upward by lifting the pull ball 403. Multiple sets of limiting protrusions 401 are fixedly connected to the bottom outer wall of the lock head 4. The limiting protrusions 401 are slidably connected to the limiting grooves 103A. Through the limiting of the limiting protrusions 401 and the limiting grooves 103A, the lock head 4 and the mounting platform 1 are circumferentially fixed, allowing the lock head 4 to slide vertically on the mounting platform 1, thus completing the locking and unlocking of the railing. A groove 402 is fixedly opened at the bottom of the lock head 4. An upper pressure rod 402B is fixedly connected to the center of the inner wall of the groove 402. Multiple sets of circumferential locking blocks 402A are fixedly connected to the top of the inner wall of the groove 402. A compression spring 5 is fixedly connected to the middle of the lock head 4. The other end of the compression spring 5 is fixedly connected to the bottom of the retaining ring 103B. Under the push of the compression spring 5, the lock head 4 maintains a downward trend. When the guardrail 2 is placed on the mounting platform 1, under the push of the compression spring 5, the circumferential lock block 402A is inserted into the circumferential slot 203, and the upper pressure rod 402B passes through the upper opening 201B to press the limiting post 601, thereby controlling the locking assembly 6 to lock.
[0035] like Figure 6 , Figure 7 and Figure 8 As shown, the guardrail 2 includes a vertical rod 201. A circumferential groove 203 is fixedly provided at the top of the vertical rod 201. Multiple sets of horizontal rods 202 are fixedly connected to the side wall of the vertical rod 201. A vertical sliding cavity 201A is fixedly provided inside the vertical rod 201. An upper opening 201B is fixedly provided at the top center of the vertical sliding cavity 201A, and a lower opening 201C is fixedly provided at the bottom center of the vertical sliding cavity 201A. A horizontal groove 2 is fixedly provided on the inner wall of the lower opening 201C. 01D, the horizontal groove 201D extends outward to the outside of the vertical rod 1 201. The horizontal sliding cavity 202A is fixedly opened inside the horizontal rod 1 202. The sliding opening 202B is fixedly opened on the side wall of the horizontal rod 1 202. The sliding opening 202B is slidably connected to the extrusion slider 605. When the extrusion slider 605 is extruded, it will extend the sliding opening 202B upward, thereby extruding the inner wall of the horizontal rod 2 302 and limiting and fixing the horizontal rod 1 202 and the horizontal rod 2 302.
[0036] like Figure 9 , Figure 10 and Figure 11 As shown, the locking assembly 6 includes a limiting post 601 and a squeezing slide post 602. The limiting post 601 is slidably connected to the vertical sliding cavity 201A. Multiple limiting ports 601A are fixedly opened on the side wall of the limiting post 601. The bottom of the limiting port 601A is a straight groove design, and the upper part of the limiting port 601A is a slanted opening design. When the limiting post 601 slides upward, the squeezing slide post 602 is allowed to be stuck in the limiting port 601A. When the limiting post 601 moves downward, the slanted opening at the upper part of the limiting port 601A pushes the squeezing slide post 602 backward, causing it to disengage from the limiting port 601A.
[0037] A compression spring 603 is fixedly connected to the bottom of the limiting post 601. The other end of the compression spring 603 is fixedly connected to the inner wall of the bottom of the vertical sliding cavity 201A. Under the push of the compression spring 603, the limiting post 601 maintains an upward trend. The elastic coefficient of the compression spring 603 is less than that of the compression spring 5. A lower pressure rod 601B is fixedly connected to the center of the bottom of the limiting post 601. The lower pressure rod 601B is slidably connected to the lower opening 201C. A locking post 604 is provided at the lower part of the lower pressure rod 601B. The locking post 604 is slidably connected to the horizontal groove 201D. An axial locking rod 604A is fixedly connected to one end of the locking post 604. The axial locking rod 604A is inserted into the groove ring 102A to achieve axial fixation between the guardrail 2 and the mounting platform 1. A pressing block 604B is fixedly connected to the other end of the locking post 604. The downward pressure rod 601B moves downward, pressing the pressure stop 604B, and the axial locking rod 604A is inserted into the groove ring 102A, axially fixing the limit post 601 to the mounting table 1.
[0038] like Figure 12As shown, the extrusion slide column 602 is slidably connected to the transverse sliding cavity 202A. A second compression spring 602B is fixedly connected to the rear end of the extrusion slide column 602. The other end of the second compression spring 602B is fixedly connected to the side wall of the transverse sliding cavity 202A. Under the push of the second compression spring 602B, the extrusion slide column 602 maintains a tendency to move to the right. The elastic coefficient of the second compression spring 602B is less than that of the third compression spring 603. The right end of the extrusion slide column 602 is designed with a bevel, which can be inserted into the limiting port 601A. A sloping groove 602A is fixedly opened on the rear side wall of the extrusion slide column 602. An extrusion slider 605 is slidably connected to the sliding port 202B. The extrusion slider 605 is in slidable contact with the sloping groove 602A. When the extrusion slide column 602 slides backward, the sloping groove 602A extrudes the extrusion slider 605 outward.
[0039] Working principle:
[0040] 1. Based on the area that the steel structure building needs to be enclosed, install and fix the mounting platform 1, take out guardrail 1 2 and guardrail 2 3, insert the crossbar 1 202 into the inner wall of the crossbar 2 302, and adjust the relative distance between the two.
[0041] 2. Lift the pull ball 403 upwards, insert the vertical rod 201 into the fixed socket 102, rotate the guardrail 2 to the appropriate angle, and release the pull ball 403;
[0042] 3. Under the push of the compression spring 5, the lock head 4 moves downward, and the circumferential locking block 402A is inserted into the circumferential slot 203 to circumferentially lock the guardrail 2.
[0043] 4. The upper pressure rod 402B passes through the upper opening 201B and presses down to squeeze the limiting post 601. Since the elastic force of the compression spring 5 is greater than that of the compression spring 603, the limiting post 601 is squeezed downward and moved. The lower pressure rod 601B passes through the lower opening 201C and squeezes the locking post 604 to both sides. The axial locking rod 604A is inserted into the groove ring 102A to axially lock the guardrail 2.
[0044] 5. The downward movement of the limiting post 601 pushes the extrusion slide 602 out of the limiting port 601A. The extrusion slide 602 moves backward, and the inclined groove 602A extrudes the extrusion slider 605. The extrusion slider 605 extends upward out of the sliding port 202B and contacts and rubs against the inner wall of the crossbar 2 302, thus fixing the distance between guardrail 1 2 and guardrail 2 3.
[0045] 6. Insert the second vertical rod 301 into the fixing socket 102, and release the pull ball 403 to complete the circumferential fixing of the second guardrail 3.
[0046] This utility model, by setting up an installation platform 1, guardrail 1 2, and guardrail 2 3, allows for the arbitrary adjustment of the guardrail width and the angle between the guardrail and the installation platform 1 according to the site conditions, enabling the splicing and fixing of multiple sets of guardrails to complete the enclosure work for steel structure buildings. By setting up a lock head 4, when the user lifts the lock head 4, the guardrail can be installed, and the distance between guardrail 1 2 and guardrail 2 3 can be adjusted, changing the installation angle between the guardrail and the installation platform 1. This allows for adjustment of the guardrail according to the actual conditions of the steel structure building. Pressing down the lock head 4 locks the distance between guardrail 1 2 and guardrail 2 3, and locks the posture of the guardrail relative to the installation platform 1, thus realizing the enclosure work.
