Description

Technical Field

[0001] The utility model belongs to the technical field of right-angle turning formwork for anti-collision guardrails, and particularly relates to a right-angle turning formwork for on-site casting of anti-collision guardrails. Background Technique

[0002] As an important part of traffic infrastructure, the design and construction of anti-collision guardrails are crucial for improving road safety and driving comfort. In traffic facilities such as highways and bridges, situations where right-angle turns need to be set often occur. Due to the inclined surfaces on the inner and outer sides of the guardrail, there are gaps at the intersection, and the longitudinal and transverse guardrails cannot be smoothly connected. The 90° intersection angle guardrail is prone to sharp corners; moreover, when removing the guardrail formwork, workers have violent removal behaviors, which are likely to cause damage to the surface of the guardrail, resulting in the degradation of the guardrail quality and damage to the guardrail formwork, which is not conducive to the reuse of the guardrail.

[0003] After retrieval, the prior art publication number: CN 216006768 U is an anti-collision guardrail formwork structure and an anti-collision guardrail formwork pouring system. Among them, the anti-collision guardrail formwork structure includes formwork bodies oppositely arranged on both sides of the embedded steel bars. Horizontally opened on the outer side surfaces of the two formwork bodies at opposite positions are a plurality of upper draw bar holes and lower draw bar holes. A draw bar is slidably installed left and right in each pair of oppositely arranged upper draw bar holes and lower draw bar holes. Reinforcement components are sleeved at both ends of each draw bar. The draw bar fixes the two formwork bodies on the embedded steel bars through the reinforcement components, so that a cavity to be poured is formed between the two formwork bodies; this device does not handle the sharp corner situation that appears at the intersection of the longitudinal and transverse guardrails, and the formwork removal process is complex, which is likely to cause workers to remove it violently, easily cause damage to the surface of the guardrail, resulting in the degradation of the guardrail quality and damage to the guardrail formwork, which is not conducive to the reuse of the guardrail.

[0004] Further retrieval shows that the prior art publication number: CN 218667302 U is a cast-in-place formwork structure for concrete anti-collision guardrails, including vertically arranged formwork and inclined formwork arranged oppositely, which are respectively supported by the bottom plate of the road. Paired screw rods are respectively arranged on the sides of the vertically arranged formwork and the inclined formwork facing away from the pouring cavity. The lower end of the screw rod can penetrate into the positioning holes opened at the bottom plate; the outer support rod includes a rotating sleeve installed on the screw rod outside the inclined formwork through threads. The outer wall surface of the rotating sleeve is fixed to one end of the first threaded sleeve. The axis of the first threaded sleeve is horizontal. A jack is installed in the first threaded sleeve through threads. The jack penetrates out of the other end of the first threaded sleeve; a sleeve is coaxially sleeved on the end of the jack away from the first threaded sleeve. The other end of the sleeve is fixed to the first support seat. The first support seat is hinged to the second support seat. The hinge axis of the first support seat and the second support seat is perpendicular to the central axis of the jack; this device does not handle the sharp corner situation that appears at the intersection of the longitudinal and transverse guardrails. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a formwork for the right-angle turn of the on-site cast anti-collision guardrail, which improves the problem of the smooth connection of the guardrail into an edge, shortens the construction time and improves the construction speed. At the same time, it improves the strength and integrity of the guardrail, reduces the occurrence of cracks in the later stage, and avoids the probability of being knocked and damaged during construction; during demolition, the demolition process is simple, and the formwork will not cause any damage to the anti-collision guardrail when it is detached. At the same time, it also protects the formwork itself and avoids the damage of the formwork caused by the violent demolition of workers, thus ensuring the reusability of the formwork.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] A formwork for the right-angle turn of the on-site cast anti-collision guardrail includes an outer formwork, a handwheel, a tie rod, a top block, an inner formwork, and a support mechanism; both the outer formwork and the inner formwork are arc-shaped; grooves are provided on both the outer formwork and the inner formwork, and the top block is arranged in the groove and fits with the groove. One side of the top block is provided with a lead screw I, and the top block is rotatably connected to one end of the lead screw I. The lead screw I is threadedly connected to the outer formwork and the inner formwork, and the handwheel is connected to the end of the lead screw I away from the top block; through holes II are provided at the bottoms of both the outer formwork and the inner formwork, and the through holes II on the two formworks correspond to each other. The tie rod is arranged in the through holes II, and the bottoms of the outer formwork and the inner formwork are fixed by nuts. Through holes I are provided on both sides of the outer formwork and the inner formwork for connecting with other splicing formworks; the support mechanism is located on one side of the outer formwork, and fixing mechanisms are provided at the tops of the outer formwork and the inner formwork; during pouring, the through holes I of the outer formwork and the inner formwork correspond to the through holes of other splicing formworks and are fixedly connected by through-hole bolts and nuts, so as to form a pouring cavity between the two formworks. The tie rod is inserted into the through holes II, and the bottoms of the outer formwork and the inner formwork are fixed by nuts. The fixing mechanisms fix the tops of the outer formwork and the inner formwork to prevent the distance between the two formworks from shifting when concrete enters between the two formworks. The support mechanism is installed on one side of the outer formwork for support to prevent the formwork from collapsing; during formwork removal, first remove the bolts and nuts between the outer formwork and the inner formwork and other splicing formworks, then remove the support mechanism and the fixing mechanism, and finally disconnect the tie rod from between the two formworks. Rotate the lead screw I through the handwheel, and use the top block to press against the anti-collision guardrail to separate the outer formwork and the inner formwork from the cast anti-collision guardrail.

[0008] The support mechanism includes a fixed bottom plate, a connecting block, a threaded rod, and a sleeve. The fixed bottom plate is arranged on one side of the outer formwork. A number of through holes are reserved on the fixed bottom plate, and expansion bolts can be used to pass through the through holes to fix the fixed bottom plate on the ground. The sleeve is arranged between the fixed bottom plate and the outer formwork. Two sections of internal threads with opposite helix directions are provided on the inner wall of the sleeve. There are two groups of threaded rods, which are respectively threadedly installed at both ends of the sleeve. The connecting block is installed at one end of the threaded rod. Fixed blocks are installed on the fixed bottom plate and the outer formwork, and the connecting block and the fixed block are pin-connected by a pin. A through hole is provided on one side of the pin, and a split pin is inserted into the through hole. Two groups of threaded rods and sleeves are installed on the fixed bottom plate, which are respectively used to support the top and bottom of the outer formwork. During operation, the fixed bottom plate is fixed on the ground by expansion bolts. One group of the two groups of threaded rods is pin-connected to the outer formwork, and the other group is pin-connected to the fixed bottom plate. The two groups of threaded rods are adjusted through the sleeve to fix the outer formwork by the entire support mechanism and prevent the formwork from collapsing during pouring. During demolition, the split pin is pulled out from one end of the pin, and the pin is pulled out from one side of the connecting block, so that the connecting block and the fixed block are separated, and the threaded rod and the sleeve are separated between the outer formwork and the fixed bottom plate. Then, the expansion bolts are removed to separate the fixed bottom plate from the ground, and finally the demolition of the support mechanism is completed.

[0009] The fixing mechanism includes a handle, a connecting rod I, a connecting rod II, a connecting rod III, a spring bin, a spring, and an arc guide plate; the handle is installed on the connecting rod III, and the connecting rod I and the connecting rod II are respectively installed at both ends of the connecting rod III and are rotatably connected to the connecting rod III; a buckle I is provided at one end of the connecting rod I, and the buckle I is rotatably connected to the connecting rod I; a buckle II is provided at one end of the connecting rod II, and the buckle II is rotatably connected to the connecting rod II; the arc guide plate is fixedly installed on one side of the connecting rod I and the connecting rod II, and a through hole is provided on the arc guide plate; the spring bin is fixedly installed at both ends of the bottom of the connecting rod III, and the spring is installed in the spring bin; a thimble is provided on the top of the arc guide plate, and the thimble is slidably connected to the spring bin, and one end of the thimble passes through the connecting rod III and is slidably connected to the connecting rod III; the thimble moves with the rotating axis as the center of the circle, and the center of the arc guide plate is consistent with the center of the thimble movement, so that the thimble only moves along the arc guide plate, and the bottom of the thimble is a right triangle; the inclined surface of the thimble is a sliding surface to ensure that the top of the outer template and the inner template are not fixed When tightening, the ejector pin can still slide out into the next through hole after entering the through hole in the arc guide plate. The vertical surface can prevent the ejector pin from sliding out of the through hole of the arc guide plate counterclockwise due to the outward tension of the template when pouring the template, thereby loosening the fixing mechanism and causing the distance between the top of the outer template and the inner template to shift. When working, buckle I is clamped on the top of the inner template, and buckle II is clamped on the top of the outer template. The handle is rotated clockwise to drive connecting rod I and connecting rod II to shrink toward the center, so that the ejector pin moves along the arc guide plate, and buckle I and buckle II shrink inward to fix the outer template and the inner template. At this time, the spring pushes the ejector pin into the through hole in the arc guide plate to fix the position of connecting rod I and connecting rod II. When dismantling, lift the ejector pins at both ends of connecting plate III to make the bottom of the ejector pin detach from the through hole on the arc guide plate, and then rotate the handle counterclockwise to drive connecting rod I and connecting rod II to expand outward, so that buckle I and buckle II slide outward, thereby achieving the purpose of disassembly.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1) Both the outer and inner formworks are arc-shaped, which not only improves the problem of the guardrail being connected into edges and corners, but also shortens the construction time and increases the construction speed. At the same time, it improves the strength and integrity of the guardrail, reduces the chance of cracks in the later stage, and avoids the chance of bumps and damage during construction;

[0012] 2) Use the hand wheel to turn the screw I, and use the top block to support the anti-collision guardrail, so that the outer template and the inner template are separated from the cast anti-collision guardrail, ensuring that the template will not cause any damage to the anti-collision guardrail when it is separated. At the same time, it also protects the template itself and avoids damage to the template caused by violent removal by workers, thereby ensuring the reusability of the template;

[0013] 3) The bottom of the ejector pin is a right triangle; the inclined surface of the ejector pin is a sliding surface, which ensures that when the top of the outer template and the inner template are not fixed tightly, the ejector pin can still slide out along the inclined surface into the next through hole after entering the through hole in the arc guide plate. The vertical surface can prevent the ejector pin from sliding out of the through hole of the arc guide plate counterclockwise due to the outward tension of the template when pouring the template after entering the through hole in the arc guide plate, thereby loosening the fixing mechanism and causing the distance between the top of the outer template and the inner template to shift;

[0014] 4) Buckle I is stuck on the top of the inner template, and buckle II is stuck on the top of the outer template. Turn the handle clockwise to drive connecting rods I and II to shrink toward the center, so that the ejector pin moves along the arc guide plate. Buckle I and buckle II shrink inward to fix the outer and inner templates. At this time, the spring pushes the ejector pin into the through hole in the arc guide plate to fix the position of connecting rods I and II. When dismantling, lift the ejector pins at both ends of connecting rod III to make the bottom of the ejector pin detach from the through hole on the arc guide plate, and then turn the handle counterclockwise to drive connecting rods I and II to expand outward, so that buckle I and buckle II slide outward. The fast fixing and disassembly of the fixing mechanism is realized, which greatly shortens the construction time and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
