Abstract
The utility model discloses a highroad steel guardrail upright-post heightening device. The upright-post heightening device mainly comprises an outer tube (1) and an inner linking tube (2). One end in the outer tube (1) is connected with the inner linking tube (2), a mounting hole (3) is arranged on the upper part of the outer tube (1), a post cap (5) is arranged on the top of the outer tube (1) and a mounting hole (4) is arranged at the lower part of the inner linking tube (2). The whole constitutes an upright-post heightening device. The utility model, by mounting a heightening outer tube on the original upright-post via the inner linking tube, can effectively overcome the disadvantages of the conventional handling method by using the rail to heighten, reduces the loss brought for pulling out, transporting and constructing the upright-post, thereby greatly saving construction cost, reducing construction difficulties, narrowing project duration and meeting with the anti-collision design requirements for guardrail.
Description
Affiliated technical field
The utility model belongs to the highway traffic safety facility, is specifically related to highway steel fence upright heightening device.
Background technology
The highway steel guardrail is that the vehicle that tries to forestall traffic accidents sweeps away roadbed and hits facility for the anti-side of accident vehicle energy dissipating, speedway or Class I highway are after several years operation or because of construction Craft or backward in techniquely caused the road surface damage, when perhaps other reasons needs road pavement to carry out the reinforcement transformation, traffic safety facilities---corrugated guardrail, just need raise adjustment, to satisfy crashproof requirement for height as integral body.Traditional method is that former guardrail board is pulled down, column is pulled up, shipped off-site, in factory, column is rearranged zinc-plated after, squeeze into roadbed again, guardrail board is installed.There is following problem in this way: when 1. column pulls up, influence subgrade stability, have hole dark more than a meter, need it is tamped; When 2. column pulls up, can cause certain deformation, damage; 3. want the column lower port to handle as recycling, cause distortion when squeezing into originally, draw out the earth in the column lower end, or partly clip sub-fraction to the end opening distortion is serious, this treating method can influence the crashproof intensity of column after squeezing into again; 4. pull up and the cost of transportation height, the duration is also long, and this traditional method also will be driven piles again, and the field work time is long.
Summary of the invention
The purpose of this utility model is: occur above problem in the transformation for fear of raising in guardrail board, a kind of highway steel fence upright heightening device is provided, column is raised and is adopted the workshop processing, reduce the field work difficulty, former column is not done traditional pulling out, transport squeeze into and turn over the worker, only increase at the scene of doing, reduce difficulty of construction, save cost, the reduction of erection time, whole structure is attractive in appearance.
Technical solution of the present utility model is: this column heightening device mainly is made up of outer tube, inside connecting tube, end in outer tube connects inside connecting tube, and installing hole is opened on the other end top of outer tube, and cap is installed at the outer tube top, installing hole is opened in the inside connecting tube bottom, and integral body is the column heightening device.
The making of column heightening device: 1. former fence upright top use increase outer tube and former column same in external diameter and material, the length of outer tube is that the height of increasing is the height that totally raise on the road surface; 2. the column tube of increasing connects the inside connecting tube that one section external diameter of employing is slightly less than former column internal diameter with former column, its bending tensile strength of inside connecting tube is not less than former column, in the workshop, insert inside connecting tube in the outer tube and weld together, respectively bore installing hole apart from top 10cm, inside connecting tube apart from bottom 10cm place at outer tube respectively then, installing hole is used to increase carriage or obstruction block installation on the outer tube, installing hole is more bigger than former column carriage or obstruction block installing hole on the inside connecting tube, so that overcome alignment error when installing with the carriage of former column or obstruction block; 3. weld, punch finish after, whole galvanizing makes heightening device, heightening device can be transported to the job site and installs then.
The beneficial effects of the utility model: this column heightening device is installed on former column by inside connecting tube and is increased outer tube, the inside and outside heightening device that links to each other can with former guardrail one integrated mass, whole structure is attractive in appearance, can overcome the conventional guard rail slab integral effectively and raise existing shortcoming in the treating method, reduce column extract, transport, construct loss and squeeze into expense once more, save construction cost widely, reduce difficulty of construction, reduction of erection time, satisfy the crashproof designing requirement of guardrail.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the scheme of installation of Fig. 1.
Among the figure: 1. outer tube, 2. inside connecting tube, 3,4. installing hole, 5. cap, 6. guardrail board.
The specific embodiment
As shown in Figure 1, this column heightening device mainly is made up of outer tube 1, inside connecting tube 2, and the end in outer tube 1 connects inside connecting tube 2, installing hole 3 is established on the other end top of outer tube 1, cap 5 is installed at outer tube 1 top, and installing hole 4 is established in inside connecting tube 2 bottoms, and integral body is the column heightening device.
The making of fence upright heightening device: 1. raise and highly determine the main degree that fence upright increases, promptly outer length of tube according to the road surface; 2. inside connecting tube length is 30cm, and wherein 10cm stretches into the outer tube welding; 3. after welding is finished, bore installing hole at 10cm place, distance outer tube top, be used to raise rear mounting bracket or obstruction block, bore installing hole at 10cm place, distance inside connecting tube bottom, being used to increase part links to each other with the carriage or the obstruction block installation of former principal post, the aperture is more bigger than former column carriage installing hole, is used to overcome the error when installing; 4. whole galvanizing promptly made the column heightening device after boring was finished.
The column heightening device is on-the-spot to be installed: installing now is that fence upright is increased the transformation difficult point, because former column is when squeezing into originally, the part column mouth of pipe has certain deformation, give to increase to install and bring certain difficulty, can use conical wedge that the distortion mouth of pipe is carried out manually " expansion " squeezes into to make things convenient for inside connecting tube, must keep installing hole to aim at when squeezing into, squeeze into put in place after, the bolt that uses former carriage that diameter is installed equally is connected firmly heightening device and former column.
Corrugated sheet is installed: as shown in Figure 2, the column heightening device installs can install obstruction block or carriage, and it is linear to adjust corrugated sheet then, and so far steel guard rail is raised to transform and finished.
