Abstract
The utility model relates to an angle steel serrated ramp, wherein, the angle steel serrations are fixedly connected to a concrete base, the upper parts of the angle steel serrations are cast with a fine stone concrete layer; a group of angle steel serrations and the fine stone concrete layer are arranged in step shapes to form a serrated ramp. The rears of the angle steel serrations are provided with reinforcing ribs which can improve the rigidity of the angle steel serrations. The angle steel serrations are fixed on the concrete base through expansion bolts. The angle steel serrations are formed by steel angles with L-shaped cross-sections. The utility model has the advantages that: the angle steel serrations are selected as the serrations of the auto ramp, which effectively solves the common quality problems that the serrations of the ramp can crack and scale off; the auto ramp constructed by the technique has orderly, uniform and handsome serrations, firm pavement, steady auto driving, no cracking and peeling on the ramp; the special tool is saved when the serrated surface course is done; at the same time, the effect of the impression is greatly improved.
Description
Technical field
The utility model relates to the field, ramp, mainly is a kind of angle steel sawtooth ramp.
Background technology
In the existing building construction, garage ramp operated by rotary motion toothing is to increase frictional force, but the sawtooth non-slip ramp that adopts adopts pea gravel concreten to add the mortar face and receives the light making usually, the ramp is as the highest section of garage frequency of utilization, under the frequent effect of the automobile of coming in and going out, very easily produce mortar sawtooth cracking, peeling phenomenon, can use the garage when reprocessing and cause very big influence.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, and a kind of angle steel sawtooth ramp is provided, and is applicable to the anti-skidding serrated portion of car ramp, with the shock resistance that increases automobile sawtooth ramp, anticracking and performance such as wear-resisting.Avoided the large tracts of land phenomenon of doing over again, ramp overall appearance quality also can be improved significantly.
The utility model solves the technical scheme that its technical problem adopts: this angle steel sawtooth ramp, the angle steel sawtooth is fixedly connected on the concrete base layer, the pea gravel concreten layer has been built on the top of angle steel sawtooth, and one group of angle steel sawtooth and pea gravel concreten layer are step-like arrangement and form jagged ramp.
The ribs that strengthens its rigidity is established at the back of described angle steel sawtooth.
Described angle steel sawtooth is fixed on the concrete base layer by expansion bolt.
Described angle steel sawtooth is made of the L-shaped angle steel in cross section.
The utility model beneficial effect is: select for use the angle steel sawtooth as the car ramp sawtooth, solved the common quality defect of ramp sawtooth cracking, peeling phenomenon effectively.Adopt the car ramp sawtooth of this technology construction, sawtooth is neat, unified, attractive in appearance, lays firmly, and running car is steady, and the ramp does not have the advantage of cracking, peeling phenomenon, and when doing the zigzag surface layer, has saved special tool; The impression effect improves greatly simultaneously.
Description of drawings
Fig. 1 is that the utility model master looks cross-sectional view
Among the figure: angle steel-1, expansion bolt-2, concrete base layer-3, ribs-4, pea gravel concreten layer-5.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1: this angle steel sawtooth ramp, ramp surface layer serrated portion adopts angle steel sawtooth 1, angle steel sawtooth 1 is fixedly connected on (also can be pre-buried) on the concrete base layer 3 by expansion bolt 2, the top of angle steel sawtooth 1 has been built 5, one groups of angle steel sawtooth 1 of pea gravel concreten layer and pea gravel concreten layer 5 and has been step-like arrangement and forms jagged ramp.
Adopt the L-shaped equal leg angle in cross section as car ramp sawtooth ingredient in the present embodiment, the angle steel bottom is every bore a circular hole every 30cm, the circular hole spacing is identical with expansion bolt 2 spacings, be convenient to expansion bolt 2 pass with concrete base layer 3 (ramp base plate) fixing, simultaneously at the angle steel back every 60cm welding ribs 4 to strengthen its rigidity.In place fixing after, with pea gravel concreten grouting, promptly the surface is wipeed off the twice receipts light of wiping one's face after filling up concrete and vibration compacting before initial set with floating rule.
Construction point:
1, angle steel processing
1 angle steel length should be got by the full pattern size is disconnected, and as the need splicing, then splicing welding joint need meet " Construction of Steel Structure inspection of quality standard " GB50205-2001 requirement.
Anchor hole must adopt machine drilling on 2 angle steel, forbids to use the electric welding reaming.
2, angle steel is laid and is installed
Angle steel adopts expansion bolt to be fixed on the concrete base layer, and the laying of requirement angle steel is firm during laying, seam is straight.Note following problem:
1), carry out and confide a technological secret, allow constructor's detail knowledge construction technology and key points for operation.
2), forbid to use the angle steel of torsional deformation, materialman should be strengthened the check to the material of marching into the arena, quality person checks on, and stops poor quality, defective material is marched into the arena, and improves raw material quality and closes.
3), work out supporting setting tool, the cut quality of raising angle steel and the accuracy of cutting position.
3, grouting
Angle steel installs cleaning, moistening being in the milk afterwards, and grouting adopts strength grade to be not less than the C20 pea gravel concreten, and after concrete vibrating was closely knit, surperficial quadric-plastering was received light.
4, finished product protection
After the mortar surface construction is finished, in time carry out the covered with plastic film maintenance, use the material that easily fades, inaccurate upward people in 7 days curing times with anti-pollution surface layer to surface layer.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
