Abstract
The utility model discloses a kind of tool-type balcony, floor face frontier defense protection unit, hole, limit of facing in order to be formed balcony or floor is protected, it comprises upper and lower two protection mechanisms be arranged in parallel, each protection mechanism comprises cross bar, fixed end and expansion bolt, the two ends of cross bar are inserted in fixed end respectively, the sidewall of fixed end near crossbar end has circular hole, expansion bolt by this circular hole fixed end is fixed on face both sides, hole, limit concrete structure on.The utility model has the advantages that: this protective device structure is simple and reliable, does not take fastener, and material deterioration inside is little, protection effect is good; Meanwhile, installation and removal are convenient, save a large amount of labour costs, also improve speed of application.
Description
Technical field
The utility model belong to construction safety protection field, be specifically related to a kind of tool-type balcony, floor face frontier defense protection unit.
Background technology
Safety in production is an important process of construction project management, restrict by working procedure, there will be in building construction process and all kinds ofly face hole, limit, in order to conscientiously ensure the personal safety of operating personnel, also in order to prevent article falling from high altitude, must formulate and implement all kinds of safeguard procedures of facing hole, limit.Especially the balcony existed a large amount of, floor face hole, limit, more need formulate and implement effective safeguard procedures.
Although existing hole, the limit protection specification calls that faces adopts tool-type safeguard procedures, but all kinds of safeguard procedures majorities of current employing are not tool-types, but are fixed on after becoming guard rail by the combination of materials such as scaffolding steel pipe, fastener concrete structure realizes.Owing to not forming tool-type protection system, pacify at every turn, tear open and all need at substantial artificial; After guard rail is removed, the work for the treatment of of guard rail and concrete structure connecting portion is pretty troublesome.This kind of safeguard procedures not only efficiency of construction are low, and pacifying, tearing open in process, and fastener usually can be lost, and causes waste of material.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and reliable for structure, mount and dismount tool-type balcony easily, floor face frontier defense protection unit.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of tool-type balcony, floor face frontier defense protection unit, hole, limit of facing in order to be formed balcony or floor is protected, it comprises upper and lower two protection mechanisms be arranged in parallel, each protection mechanism comprises cross bar, fixed end and expansion bolt, the two ends of cross bar are inserted in fixed end respectively, the sidewall of fixed end near crossbar end has circular hole, expansion bolt by this circular hole fixed end is fixed on face both sides, hole, limit concrete structure on.
The length 300mm more than larger than the width facing hole, limit of described cross bar.
The distance of the center of described circular hole and the mouth of pipe at fixed end two ends is not less than 46.7mm.
Compared with prior art, the utility model has the advantages that: this protective device structure is simple and reliable, does not take fastener, and material deterioration inside is little, protection effect is good; Meanwhile, installation and removal are convenient, save a large amount of labour costs, also improve speed of application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in the utility model A-A to sectional drawing;
Fig. 3 be in the utility model B-B to sectional drawing.
Wherein, 1, cross bar, 2, fixed end, 21, circular hole, 3, expansion bolt, 4, hole for the expansion bolt, 5, face hole, limit, 6, concrete structure.
Detailed description of the invention:
As shown in Figure 1 to Figure 3, a kind of tool-type balcony, floor face frontier defense protection unit, hole, limit of facing in order to be formed balcony or floor is protected, it comprises upper and lower two protection mechanisms be arranged in parallel, each protection mechanism comprises cross bar 1, fixed end 2 and expansion bolt 3, the two ends of cross bar 1 are inserted in fixed end 2 respectively, and the sidewall of fixed end 2 near cross bar 1 end has circular hole 21, expansion bolt 3 by this circular hole 21 fixed end 2 is fixed on face both sides, hole, limit 5 concrete structure 6 on.
Further illustrate: cross bar 1 totally two, the A3 steel pipe by external diameter 48mm, wall thickness 3.25mm is made, its length 300mm more than larger than the width facing hole, limit 5; Fixed end 2 totally four, the stainless steel tube by external diameter 51mm, wall thickness 3mm, length 200mm is made; The diameter of circular hole 21 is 6.5mm, and the distance of the mouth of pipe at its center and fixed end 2 two ends is not less than 46.7mm; Expansion bolt 3 totally four, specification is M6, length 60mm.
Install above-mentioned tool-type balcony, floor face frontier defense protection unit time, comprise the following steps:
(1) hand-operated electric drill is utilized to bore the hole for the expansion bolt 4 that upper and lower two groups of diameters are 6.5mm on the concrete structure 6 facing both sides, hole, limit 5 of balcony or floor, and two groups of hole for the expansion bolts 4 are respectively 1200mm and 200mm apart from flooring height, the large 5mm of length of the depth ratio expansion bolt 3 of hole for the expansion bolt 4, so that effectively tighten expansion bolt 3, the center of hole for the expansion bolt 4 is 153.3mm with the distance of facing edge, hole, limit 5;
(2) fixed end 2 is inserted at cross bar 1 two ends in upper protection mechanism, then by expansion bolt 3 through hammering into above in one group of hole for the expansion bolt 4 after the circular hole 21 of fixed end 2, and tighten expansion bolt 3, make cross bar 1 two ends withstand on expansion bolt 3 side respectively and near the concrete structure 6 facing both sides, hole, limit 5;
(3) fixed end 2 is also inserted at cross bar 1 two ends in lower protection mechanism, then by expansion bolt 3 through hammering into below in one group of hole for the expansion bolt 4 after the circular hole 21 of fixed end 2, and tighten expansion bolt 3, make cross bar 1 two ends withstand on expansion bolt 3 side respectively and near the concrete structure 6 facing both sides, hole, limit 5, realize the protection of facing hole, limit 5 to balcony or floor.
Install above-mentioned tool-type balcony, floor face frontier defense protection unit time, first twist off the nut of each expansion bolt 5; Then respectively the cross bar 1 in upper protection mechanism and lower protection mechanism and fixed end 2 are taken off, to reuse; The bared end of the bar of each expansion bolt 5 is squeezed in hole for the expansion bolt 4 by recycling hand hammer, and expanding end was lost efficacy; The bar of the expansion bolt 5 finally utilizing the instruments such as nipper plier to be lost efficacy by expanding end takes out.
