Abstract

The utility model relates to a boundary guard barrier, belongs to the technical field of constructional engineering, and aims to solve the defects that the guard barrier in the prior art is difficult to disassemble, is difficult to cyclically use and has poor safety. The boundary guard barrier comprises a plurality of vertical bars and a plurality of cross bars, wherein the vertical bars are fixed with the cross bars through fasteners, and retainers used for fixing with the ground or a wall are fixedly arranged on both the bottom ends of the vertical bars and the two ends of the cross bars. The boundary guard barrier is novel in design and suitable for a high-layer cast-in-situ reinforced concrete boundary guard function. The boundary guard barrier is formed by processing a steel main material, is convenient to assemble and disassemble, has great stability and safety, does not occupy construction operation space and does not hinder a construction channel.

Description

Face frontier defense guardrail

Technical field

The utility model relates to a kind of frontier defense guardrail that faces, and belongs to construction engineering technical field.

Background technology

Along with national market economy develops rapidly, urbanization process is accelerated, land resources reduces day by day, city is high-rise, super highrise building is increasing, and economic input, human input, the technology that the security protection of " Triratna, four-hole, five face limit " in building construction process consumes has high input to be increased greatly.In the work progress of engineering construction, all unlimited edge in construction operation place all needs to carry out security protection, and with preventive works, personnel fall from eminence, avoids causing workman's casualty accident and unnecessary loss.

Traditional construction safety railing adopts steel pipe and various fastener association to form, and technique is coarse, and poor stability is difficult to meet the security protection requirement day by day strengthening; And the steel pipe using, fastener amount are large, cost is high, and takes up room, and hinders and enters operating surface construction operation; While setting up, steel pipe is inside and outside outstanding, has not only hindered current but also easily to cause personnel to collide injured.

Summary of the invention

The purpose of this utility model be to solve prior art protective guard dismounting difficulty, be difficult for have enough to meet the need the deficiency of use, poor stability, a kind of assembling facility is provided, dismantles simple and repeatedly used protective guard.

The utility model solves the technical scheme that its technical problem adopts:

Face frontier defense guardrail, comprise some montants and cross bar, between described montant and cross bar, by securing member, fix, the bottom of described montant and the two ends of cross bar be all fixed with for ground and/or the fixing holder of wall.

As preferably, described holder is comprised of fixed head and sleeve pipe, fixed head and sleeve pipe welding, and described holder was socketed by sleeve pipe and coordinating of montant or crossbar end, was also provided with the some bolts hole for fixing with ground and/or wall on described holder.

As preferably, described securing member is fastener.

As preferably, between described montant and between cross bar, equidistantly be arranged in parallel.

As preferably, the length of described some cross bars is unequal.

As preferably, described montant or cross bar form by the steel pipe of diameter 480mm, and described sleeve pipe consists of the steel pipe of diameter 350mm.

The beneficial effects of the utility model are: compared with prior art, the utility model is novel in design, is applicable to high-rise cast-in-situ steel reinforced concrete and faces frontier defense protective function; This faces frontier defense guardrail and processes with steel main material, and mounting or dismounting are convenient, good stability, and safety is good; The utility model does not take construction operation space, does not hinder construction passage.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment:

Face frontier defense guardrail, for the various unlimited edge at the construction operation scene of engineering construction process is carried out to security protection, as depicted in figs. 1 and 2, this faces frontier defense guardrail and comprises two montants 3 and two cross bars 4, two montants 3 equal in length, the length of two cross bars 4 is unequal, under the prerequisite that guarantees protection safety, can save material, between montant 3 and cross bar 4, by fastener 1, be fixedly connected with, as shown in Figure 3, the utility model is preferably installed on cross bar 4 inner side of montant 3, install, convenient disassembly, as shown in Figure 4, described holder 2 is welded by fixed head 21 and sleeve pipe 22, on described fixed head 21, be processed with four bolts hole 23, in the present embodiment, montant 3 or cross bar 4 all adopt the steel pipe of diameter 380mm to process, sleeve pipe 22 adopts the steel pipe of diameter 450mm to process.

When the utility model is used, first montant 3 and cross bar 4 are assembled by fastener 1, then cross bar 4 coordinates fit on holder 2 by two ends and sleeve pipe 22, same aforesaid operations, montant 3 coordinates fit on holder 2 by lower end and sleeve pipe 22, then will pass bolt hole 23 by expansion bolt holder will be fixed on ground or wall, complete facing the fixing of frontier defense guardrail.

Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, under the prerequisite that does not exceed the technical scheme that claim records, also has other variant and remodeling, if the quantity of montant 3 of the present utility model and cross bar 4 can also be more than three or three, between montant 3 and equidistant parallel design between cross bar 4.
