Description

Fast Installation, reparation safety barrier

The utility model relates to a kind of Fast Installation, repairs safety barrier, belongs to a kind of guard bar device of using on the highway.

Existing highway barrier is generally by column, guardrail carriage, compositions such as guardrail board.Mainly have complex structure, processing technology is difficult, and slow-footed deficiency is installed, repaired to the cost height, and the safety, the fastness that have are relatively poor.

The purpose of this utility model is, provides a kind of simple in structure, easy to process, and cost is low, safe and reliable Fast Installation, repairs safety barrier.

The purpose of this utility model reaches by the following technical programs.It is by pedestal 1, be inserted in the column 4 on the pedestal 1, column is locked at retaining mechanism 2 on the pedestal 1, be fixed on the guardrail carriage 7 on column 4 tops, the guard bar device that is installed on this carriage is formed, and its special character is, pedestal 1 is an integral body with retaining mechanism 2, retaining mechanism 2 is positioned at the top of pedestal 1, establishes locating hole on retaining mechanism 2 sidewalls, is rotary with set screw 8 on the locating hole.Locating hole and set screw are one-to-one relationship, and locating hole, set screw can respectively be one, also can respectively be 2,3 etc.Pedestal 1, retaining mechanism 2, the section configuration of column 4 can be all circle, ellipse, square, I-shaped.The protector here can be a protective guard 6, also can be the protection rope.

A kind of embodiment preferably of the utility model is, the shape of described guardrail carriage 7 is like the U type, and the U type mouth both sides of guardrail carriage 7 are provided with flank 10, and flank is provided with through hole 11.At this moment the guard bar device on this carriage is a guardrail board 6.

Second kind of the utility model embodiment preferably is to establish the steel mesh reinforcement skeleton 12 of fixedlying connected with it in pedestal 1 bottom.The adhesion of pedestal and ground has been strengthened in the setting of steel mesh reinforcement skeleton, and the anti-impact force of safety barrier is strengthened.

The utility model the third preferably embodiment be in the pedestal 1 bottom outside and steel mesh reinforcement skeleton 12 inside and outside, to establish the concrete fixed block 13 that is connected as a single entity with it.The setting of this concrete fixed block has increased the volume and the weight of pedestal, is convenient to directly bury underground at the construction field (site) use, and its stability further strengthens by impact.

The 4th kind of the utility model embodiment preferably is the waterstop ring 3 of setting up defences in the upper end surface of retaining mechanism 2.Like this, can prevent effectively that rainwater from entering locking device, in column and the pedestal, avoid them to get rusty, prolong its application life.

Because pedestal of the present utility model 1 is an integral body with retaining mechanism 2, and retaining mechanism vertical columns 4 is to reach by locating hole on it and set screw, and therefore, this guard bar structure is simple, but the time processing moulding is easy to manufacture, and cost is low.And it is convenient, fast that reparation is installed.The seemingly U type structure of guardrail carriage has further been simplified processing technology, can make the guardrail carriage one time punching molded.Whole cost can reduce 5-8%.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying this technical solution.

Embodiment 1, with reference to figure 1-Fig. 6.As shown in Figure 1, this is Fast Installation, reparation safety barrier that a guard bar device is a guardrail board 6.Pedestal 1 is a steel-casting with retaining mechanism 2, and the two is an integral body, and one-step casting forms, and the keeper of fixing on it 9 is established in the bottom of pedestal 1, is three here.On retaining mechanism 2, be provided with two orthogonal locating holes, be rotary with set screw 8 in each locating hole.Column 4 is inserted in retaining mechanism 2 and the pedestal 1, can fix the length that it stretches out by retaining mechanism 2 along pedestal 1 upper and lower slip, and waterproof grommet 3 is enclosed within on the column and with retaining mechanism 2 and contacts.Rainhat 5 is stamped on the top of column 4, and its middle and upper part is connected with guardrail carriage 7 by bolt.The structure of guardrail carriage 7 such as Fig. 4, shown in Figure 5.Its shape is like the U type, and flank 10 is established in its U type mouth both sides, establishes through hole 11 on the flank 10.This guardrail carriage is once just plastic with the bar steel plate punching press, and processing is simple, economizes material.Its two flanks and guardrail board 6 usefulness screws are connected as a single entity.During use, dig pit at the scene, pedestal 1 is put into the hole, fluid concrete then forms concrete fixed block 13, uses sand 14 cappings at last, makes itself and firm being connected as a single entity of ground.Then column 4 is inserted in the pedestal 1, adjust to predetermined altitude, by the set screw 8 of retaining mechanism 2 that column 4 is fixing, install waterproof grommet 3 then, guardrail carriage 7 and guardrail board 6 cover rainhat 5 at last.In case this guardrail is hit by car, because pedestal 1 is connected as a single entity with the earth, then only need column 4, guardrail carriage 7, guardrail board 6 are unloaded, their are repaired the back and install, or with new replacement, install and get final product.During fixed pedestal, except that fixing with concrete, also available stone, sand are fixed, but fixing more firm with concrete.

Embodiment 2, with reference to figure 7, Fig. 8, Fig. 9, Fig. 4, Fig. 5.This is improved a kind of Fast Installation, a reparation safety barrier on embodiment 1 basis.Its improvement part has 2 points: (1), in the bottom of pedestal 1 fixedly connected steel mesh reinforcement skeleton 12, this steel mesh reinforcement skeleton is a triangle, there is the twice crossbeam centre; (2), at pedestal 1 skin, inside and outside the steel mesh reinforcement skeleton 12, establish the concrete fixed block 13 that is connected as a single entity with it, the structure of other parts is identical with embodiment 1.Compare with embodiment 1, directly digging pit to bury underground at the construction field (site) gets final product, safety, firm.Under the identical situation of the depth of burying and embodiment 1, this structure is more economized material.But weight is big, and it is not too convenient to transport.

If at pedestal 1 skin, the inside and outside concrete fixed block 13 of not establishing of steel mesh reinforcement skeleton, as shown in Figure 8, then fluid concrete at the construction field (site) can reach same effect.Promptly, dig pit at the construction field (site), the pedestal 1 that is welded with steel mesh reinforcement skeleton 12 is placed on just getting in the hole, fluid concrete then, form concrete fixed block 13, this concrete fixed block 13 both with pedestal 1, steel mesh reinforcement skeleton 12 connects as one, be connected as a single entity with sand 14 on every side again, form structure as shown in figure 10.Fastness is stronger, and convenient transportation.Also the pedestal that is connected with steel mesh reinforcement skeleton 12 1 usefulness stone, sand as shown in Figure 8 can be fixed on and be mounted the position, itself and the earth are connected as a single entity.Though its fastness is little than fluid concrete, easy construction.

Embodiment 1 is usually used in the protective guard on the bridge, and embodiment 2, is usually used in the middle protective guard of road both sides or road.

If with embodiment 1; guardrail carriage 7 among the embodiment 2; change the suitable guardrail carriage that the guardrail rope is installed into; guardrail board 6 changes the guardrail rope into; the structure of other component is constant; then can form two kinds of analog structures in addition fast, install, repair the safety barrier device, this also belongs to protection domain of the present utility model.
