Abstract

A fixing device for placards can be mounted and fixed fast and conveniently. Hold-type fixing is used. The fixing device for placards comprises a placard, angle irons, nuts, bolts and self-tapping screws. The angle irons and the nuts are integrally combined and fixedly connected with the placard through the self-tapping screws. The bolts are screwed into threaded holes of the angle irons and abutted against outer surfaces, provided with vertical edges, of buildings, steel-structured columns and the like. The placard is stressed by tightening the bolts. The placard can be fixed and prevented from falling as long as self weight of the placard cannot overcome friction force between the bolts and the surfaces of the buildings and steel-structured columns. The fixing device for placards is low in manufacturing cost and timesaving and laborsaving, is made by slightly processing common angle irons on site, and can be mounted with a screwdriver and a wrench.

Description

Placard fixing device

Technical field

The present invention relates to a kind of working-yard placard fixing device, especially need for safety construction, boiler steel structure does not allow or not to destroy metope on welding, the concrete post at the scene, but needing the place of installing placard, a kind of fixing, the dismounting of taking is stationary installation easily all.

Background technology

At present, general placard is fixing all to be after selecting to need the fixed position, on steel column or concrete column that needs are fixed, welds pre-embedded bolt or with the reciprocating drill punching expansion bolt is installed, again the placard fastening nuts; Some employing ail gun nailings or fix with hammer nail stainless steel lag screws; Even the direct usefulness iron wire colligation that has is namely not attractive in appearance, dangerous to steel column yet.Above-mentioned etc. mode need to be employed many operations specialty Work tools, such as reciprocating drill, ail gun etc., brings the trouble of operation to the workmen, has reduced efficiency, has also brought unnecessary expenditure to enterprise simultaneously.

Summary of the invention

In order to overcome existing placard hypopexy part, the invention provides a kind of novel placard fixing device, this device adopts the jackscrew Force principle, so that placard simple and fast, solid and reliable is installed.

The technical solution adopted for the present invention to solve the technical problems is: use the fixedly stressed supporter of placard of placard self conduct, bolted with the effect of playing jackscrew, because this body weight of placard is lighter, bolt stressed progressively increase when fastening is enough to overcome the placard self gravitation, thereby placard is installed in the precalculated position.

This placard fixing device adopts and embraces the formula fixation, is combined by placard, angle bar, nut, bolt, self threading pin, with self threading pin angle bar is connected and fixed from the back side and placard; One side of angle bar arranges three to five self threading pin holes, and opposite side arranges a bolt through hole; Utilize the bolted effect, under the bolt effect of playing the jackscrew effect, rely on placard self to do and connect support, when fastening force is enough large, overcome own wt, being fixed to buildings, steel structure column etc. has on the outer surface of vertical edge.

Bolt on the nut aligning angle bar welds together with through hole and angle bar becomes a combiner; In the nut bore on the bolt precession angle bar, pass the bolt through hole on the angle bar, withstanding on buildings, steel structure column etc. has on the outer surface of vertical edge, placard is stressed when tighting a bolt, when the placard self gravitation can't overcome friction force between bolt and buildings, steel structure column surface and can not drop, thereby placard is fixed.

Under the welding condition, to install according to the order of bolt, angle bar, nut, nut is inboard at angle bar, holds nut with skeleton spanner and does not rotate, and another spanner swivel bolt is made state Dingan County dress.Also can reach hard-wired purpose.

Placard is close to the object that is fixed, and the space, back is less, can bear larger external force, is difficult for destroyed.

The placard that is fixed can repeat dismounting, and transposition is used, and after the dismounting, does not damage the surfaces such as fixing with it buildings, steel construction, need not to repair.

The invention has the beneficial effects as follows, need not such as reciprocating drill, ail gun etc., only use screwdriver and conventional spanner just can to install voluntarily by specific purpose tool, installation, convenient disassembly, fixation be attractive in appearance.

Embodiment

Embodiment 1:

The first step: measure field needs concrete column, the steel column width of fixed position, makes the suitable label of width, on-the-spot steel column concrete post, and general width 0.5-0.8 rice just in time is fit to hang Sign Board.

Second step: intercept such as one section L40*40*5 angle bar of Fig. 5, in appropriate location shown in Figure 5 perforate, 4 φ 3 self threading pin holes, 1 φ 10.5 screw hole, at screw hole outside centering adjustment, M10 nut shown in Figure 5 of spot welding is combined into subassembly shown in Figure 6.

The 3rd step: fetch placard, use self threading pin shown in Figure 7 subassembly quadruplet shown in Figure 6, tighten and get final product in Fig. 1 and Fig. 2, Fig. 3, four jiaos of appropriate locations shown in Figure 4.

The 4th step: placard is taken the scene, select suitably height, place placard, use the bolt that plays the jackscrew effect shown in Figure 7, adjust that it is stressed, so that placard is fixed on concrete column, steel column marginal position, design sketch such as Fig. 8.

The installation procedure explanation:

1. smallclothes combination: the angle bar perforate is combined into Fig. 6 subassembly;

2. placard is pre-assembled: four jiaos of appropriate locations of subassembly shown in Figure 6 and placard are fixed;

3. on-the-spot fixing: as in the outside, pillar two edges, to adjust fastening bolt, fixedly placard.

Embodiment 2:

The first step: identical with embodiment 1.

Second step: intercept such as one section L40*40*5 angle bar of Fig. 5, in appropriate location shown in Figure 5 perforate, 4 φ 3 self threading pin holes, 1 φ 10.5 screw hole.

The 3rd step: identical with embodiment 1.

The 4th step: placard is taken the scene, select suitably height, place placard; Unit does not have welding condition, installs according to the order of bolt, angle bar, nut, and nut is inboard at angle bar, holds nut with skeleton spanner and does not rotate, and another spanner swivel bolt is made state Dingan County dress.Adjust that it is stressed, so that placard is fixed on concrete column, steel column marginal position, can reach equally fixed effect.
