Description

Technical Field

[0001] This utility model relates to the field of construction guardrail technology, and in particular to a reinforcement device for construction guardrails in construction buildings. Background Technology

[0002] During construction, construction fences need to be installed around the construction area to warn unauthorized personnel that entry is prohibited. There are various types of construction fences. In use, multiple individual small fences are usually assembled and spliced ​​together. When splicing them together, multiple fences are usually directly interlocked. Some fences that do not have a connecting function can only be placed side by side. During use, it is easy to separate two fences, which can easily lead to unauthorized personnel entering.

[0003] For example, a construction guardrail reinforcement device disclosed in Chinese patent literature (publication number: CN221609713U) has three adjustment mechanisms set together between two clamping blocks. These three adjustment mechanisms can control the size of the clamping space between the two clamping blocks, making the device adaptable to different types of guardrails. At the same time, the adjustment holes used for adjustment in the adjustment mechanism are set as triangular adjustment holes. When the device is adjusted through the adjustment mechanism, only specific tools can be used for adjustment, which can prevent the device from being disassembled and lost by others during daily use.

[0004] However, during assembly and disassembly, operators need to repeatedly turn the screw rod with professional tools. Connecting or disassembling a single guardrail requires rotating the screw rod multiple times to adjust the spacing of the clamping blocks. The operation process is cumbersome. In construction scenarios, dozens or even hundreds of guardrails often need to be assembled or disassembled in batches, which increases the manual labor force and seriously reduces the efficiency of assembly and disassembly, making it difficult to meet the needs of efficient construction. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the current reinforcement and disassembly of a batch of railings is not only cumbersome and labor-intensive, but also inefficient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A construction guardrail reinforcement device for a construction building includes a first clamping block, the front of which is provided with a convenient disassembly and assembly mechanism.

[0008] The convenient assembly and disassembly mechanism includes guide rods, one end of two guide rods being symmetrically distributed and fixedly connected to the front of the first clamping block, the front of the first clamping block being fixedly connected to symmetrically distributed oblique racks, and the front of the first clamping block being provided with symmetrically distributed first arc-shaped clamping grooves.

[0009] Preferably, a first arc-shaped anti-slip pad is fixedly connected to the inner wall of the first arc-shaped clamping groove, and a grip handle is fixedly connected to the back of the first clamping block.

[0010] Preferably, the convenient disassembly and assembly mechanism further includes a second clamping block, the back of which is provided with symmetrically distributed guide holes, one end of the guide rod is movably inserted into the inner wall of the guide hole, and the back of the second clamping block is provided with symmetrically distributed through slots.

[0011] Preferably, the front of the second clamping block is fixedly connected with symmetrically distributed fixed square tubes, one end of the fixed square tubes is connected to one end of the through groove, one end of the helical rack passes through the through groove and extends into the interior of the fixed square tubes, and the back of the second clamping block is provided with symmetrically distributed second arc-shaped clamping grooves.

[0012] Preferably, a second arc-shaped anti-slip pad is fixedly connected to the inner wall of the second arc-shaped clamping groove, and an installation through groove is provided on one side of the fixed square tube. The inner bottom wall and inner top wall of the installation through groove are rotatably connected to a rotating rod through a bearing, and an installation sleeve is fixedly sleeved on the outside of the rotating rod.

[0013] Preferably, the two ends of the mounting sleeve are fixedly connected with symmetrically distributed torsion springs, one end of each torsion spring is fixedly connected to the inner bottom wall and the inner top wall of the mounting groove, respectively, and the outside of the mounting sleeve is fixedly connected with a limit strip.

[0014] Preferably, one end of the limiting strip is movably engaged with the tooth groove of the inclined rack, and a pressing plate is fixedly connected to the outside of the mounting sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the cooperation between the guide rod and the guide hole achieves rapid positioning, avoiding positional deviations during assembly. The snap-fit ​​structure between the helical rack and the limiting strip, along with the automatic reset of the torsion spring, achieves self-locking after connection, allowing for tool-free fixing. This ensures connection stability and eliminates the need for screwing. The simultaneous pressing of the disassembly plate prevents loosening caused by accidental activation of a single pressing plate and allows for quick release of the limit, significantly simplifying the disassembly and assembly process. Furthermore, the handle design enhances ease of operation. Overall, this invention achieves high efficiency and labor-saving disassembly and assembly of batch guardrails, significantly reducing manual labor and improving disassembly and assembly efficiency in construction scenarios.

[0027] Example

[0028] like Figures 1-5 As shown, this utility model provides a technical solution: a construction guardrail reinforcement device for construction buildings, including a first clamping block 1, which serves as the basic load-bearing component for guardrail connection. To achieve quick assembly and disassembly of the guardrail, a convenient assembly and disassembly mechanism is provided on the front of the first clamping block 1. This mechanism can achieve self-locking and quick unlocking through the cooperation of mechanical structures without the need for additional tools.

[0029] The convenient assembly and disassembly mechanism includes guide rods 2. One end of the two guide rods 2 is symmetrically distributed and fixedly connected to the front of the first clamping block 1. The symmetrical layout can ensure that the force is balanced when the first clamping block 1 and the second clamping block 25 are spliced, avoiding one-sided offset. The front of the first clamping block 1 is fixedly connected with symmetrically distributed oblique racks 21. The tooth surface is designed to be inclined, which can automatically squeeze the limiting component during splicing, realizing tool-free advancement. The front of the first clamping block 1 is provided with symmetrically distributed first arc-shaped clamping grooves 22. The arc structure can adapt to the contour of the round guardrail pipe, improving the fit.

[0030] The inner wall of the first arc-shaped clamping groove 22 is fixedly connected to the first arc-shaped anti-slip pad 23, which is made of rubber with a high coefficient of friction. This pad can increase the friction with the guardrail pipe fittings to prevent slippage and loosening after connection, and can also buffer the clamping force to avoid damaging the surface of the pipe fittings. The back of the first clamping block 1 is fixedly connected to the grip handle 24, which has an ergonomic design that makes it easy for construction workers to hold it stably with one hand, thus improving the convenience of operation.

[0031] The convenient assembly and disassembly mechanism also includes a second clamping block 25, which is a clamping component that cooperates with the first clamping block. The back of the second clamping block 25 is provided with symmetrically distributed guide holes 26. One end of the guide rod 2 is movably inserted into the inner wall of the guide hole 26. The precise cooperation between the guide rod and the guide hole can realize the rapid positioning of the first clamping block 1 and the second clamping block 25, avoid positional deviation during splicing, and improve assembly efficiency. The back of the second clamping block 25 is provided with symmetrically distributed through slots 27, which provide a channel for the insertion of the helical rack 21.

[0032] The front of the second clamping block 25 is fixedly connected with symmetrically distributed fixed square tubes 28. One end of the fixed square tube 28 is connected to one end of the through groove 27, serving as a mating space between the helical rack 21 and the limiting component. One end of the helical rack 21 passes through the through groove 27 and extends into the interior of the fixed square tube 28, realizing linkage with the limiting component. The back of the second clamping block 25 is provided with symmetrically distributed second arc-shaped clamping grooves 29, which cooperate with the first arc-shaped clamping groove 22 to form a closed clamping space, adapting to guardrail pipes of different diameters.

[0033] The inner wall of the second arc-shaped clamping groove 29 is fixedly connected to a second arc-shaped anti-slip pad 210, which works together with the first arc-shaped anti-slip pad 23 to further enhance the stability of clamping. A mounting through groove 211 is opened on one side of the fixed square tube 28 to provide installation and movement space for the limiting component. The inner bottom wall and inner top wall of the mounting through groove 211 are rotatably connected to a rotating rod 212 through bearings to ensure the smoothness of the rotating component. The rotating rod 212 is fixedly sleeved with a mounting sleeve 213, which serves as the mounting carrier for the limiting component and the torsion spring 214.

[0034] The two ends of the mounting sleeve 213 are fixedly connected with symmetrically distributed torsion springs 214. One end of each torsion spring 214 is fixedly connected to the inner bottom wall and the inner top wall of the mounting through groove 211, respectively. The symmetrically distributed torsion springs 214 can provide balanced reset torque to ensure stable reset of the limiting component. The external fixed connection of the mounting sleeve 213 is a limiting strip 215, the shape of which is adapted to the tooth groove of the helical rack 21, so as to achieve precise snap-fit.

[0035] One end of the limiting strip 215 is movably engaged with the tooth groove of the helical rack 21. The self-locking after connection is achieved through the engagement of the tooth groove and the limiting strip 215, preventing the first clamping block 1 and the second clamping block 25 from loosening. The external fixed connection of the mounting sleeve 213 is a pressing plate 216, which makes it easy for construction personnel to release the limit by pressing. The design of pressing the two pressing plates 216 simultaneously can avoid accidental unlocking caused by the accidental contact of a single plate, thus improving the safety of use.

[0036] The working process of this utility model:

[0037] Step 1: The construction worker first brings the two guardrails to be connected together at one end to align the adjacent pipes. Then, the worker holds the handle 24 on the back of the first clamping block 1 and lifts the first clamping block 1 so that the two first arc-shaped clamping grooves 22 on the front of the first clamping block 1 are respectively attached to the surfaces of the adjacent pipes of the two guardrails, completing the initial attachment and positioning of the first clamping block 1 and the guardrail. The worker then picks up the second clamping block 25, aligns the guide hole 26 on its back with the guide rod 2 on the front of the first clamping block 1, and pushes the second clamping block 25 toward the first clamping block 1 along the extension direction of the guide rod 2.

[0038] Step two, during the pushing process, the oblique rack 21 on the front of the first clamping block 1 passes through the through groove 27 on the back of the second clamping block 25 and enters the interior of the fixed square tube 28. The oblique surface of the oblique rack 21 will press the limiting strip 215 inside the fixed square tube 28, causing the limiting strip 215 to drive the rotating rod 212 to rotate through the mounting sleeve 213. At the same time, the torsion springs 214 at both ends of the mounting sleeve 213 are twisted and stored. When the second clamping block 25 is pushed to the first arc-shaped clamping groove 22 and... When the second arc-shaped clamping groove 29 is fully closed and fits the guardrail pipe, the first arc-shaped anti-slip pad 23 and the second arc-shaped anti-slip pad 210 will fit tightly against the surface of the pipe, increasing the friction. At this time, the tooth groove of the inclined rack 21 moves to the corresponding position of the limit strip 215, and the stored torque of the torsion spring 214 drives the mounting sleeve 213 to reset, so that the limit strip 215 is inserted into the tooth groove of the inclined rack 21, completing the automatic locking. The two guardrails are firmly connected and will not loosen due to external force.

[0039] Step 3: When it is necessary to dismantle the guardrail connection, the construction personnel need to press the two pressing plates 216 on the front of the second clamping block 25 simultaneously with both hands. The pressing plates 216 drive the mounting sleeve 213 to rotate, causing the limiting strip 215 to flip and disengage from the tooth groove of the oblique rack 21, releasing the limitation on the oblique rack 21. Then, hold the grip handle 24 and pull the first clamping block 1 away from the second clamping block 25. The guide rod 2 is pulled out from the guide hole 26, and the oblique rack 21 exits from the through groove 27 and the fixed square tube 28, thus disengaging the connection between the two guardrails.
