Description

Scaffold guardrail

technical field

The invention relates to a building construction tool, especially a scaffold guardrail that can be quickly combined with one side of a scaffold to provide support and enclosure, and facilitate construction on the side.

Background technique

As shown in Figure 1, the generally known scaffold structure is to set a cross tie rod 11 respectively on the two sides of two parallel scaffolds 10 (that is, the side near the building and the opposite side) to serve as the The two scaffolds 10 are supported at a fixed distance and serve as side enclosures. Wherein, the four ends of the cross tie rods 11 are respectively detachably combined on the vertical rods 12 of the two scaffolds 10 near the upper and lower ends of the coupling pins 13.

Yet, because this two adjacent scaffolds 10 are close to a side (i.e. inner side) of building, be divided into four triangular areas by this cross brace 11, and the oblique angle of this triangular area is very important for painting, tiling. Ordinary people who are accustomed to level and moving up and down during construction, such as passing objects, will form a very large obstacle, which will affect the smoothness and efficiency of construction.

Contents of the invention

The main purpose of the present invention is to provide a scaffold guardrail that can be quickly combined on one side of the scaffold to provide support and enclosure, and can facilitate construction on the side.

Specifically, the scaffold guardrail of the present invention includes a lower cross bar, two supports, an upper cross bar, two fasteners and a plurality of connecting rods. The two supports are combined at both ends of the lower cross bar, and each of the two supports has an outward opening for them to be forked on the vertical bars on the same side of the two adjacent scaffoldings, and pressed against the vertical bars. The upper side of the bolt; the upper cross bar is located parallel to the top of the lower cross bar; and most of the connecting rods are arranged at intervals between the upper and lower cross bars, and the two ends of the connecting rods are respectively swingably combined on the upper and lower cross bars, so that the upper and lower cross bars can be horizontally close to each other.

The fastener includes a fixed half ring combined with the end of the upper cross bar, and buckled on the inner side of the vertical bar of the scaffold; A protrusion, the movable half ring is buckled on the outer side of the vertical rod, and the protrusion has a slot in the shape of an opening; a lock bar is swingably combined with the other end of the fixed half ring, and can be used for Embedded in the slot, there is a threaded section on the locking rod;

A nut is screwed on the threaded section of the locking rod, and screwed on the outside of the protrusion so that the fixed half-ring and the movable half-ring are relatively abutted to clamp the standpipe.

The upper side of the lower cross bar has a plurality of lower pivot pieces arranged at intervals, the lower side of the upper cross bar has a plurality of upper pivot pieces arranged at intervals, and the two ends of the connecting rod respectively have a connecting piece, and respectively use two shaft bolts to The two connecting pieces are pivoted to the upper pivot piece and the lower pivot piece.

The lower pivot piece has a lower pivot groove for accommodating the connecting piece at the lower end of the connecting rod, and the upper pivot piece has an upper pivot groove for accommodating the connecting piece at the upper end of the connecting rod.

The lower cross bar has a middle section and two bent sections, and the two bent sections are located at both ends of the lower cross bar middle section and make the two supports form a height difference with the middle section of the lower cross bar, thereby making the scaffold guardrail When assembled on the scaffold, its fasteners are staggered with the fasteners of the adjacent scaffold guardrails.

When the scaffolding guardrail is assembled on the scaffolding, its fasteners are located above or below the fasteners of the adjacent scaffolding guardrails having a straight lower cross bar.

The supporting member is U-shaped.

In this way, when the scaffold guardrail of the present invention is assembled on the scaffold, the lower cross bar, the upper cross bar and a plurality of connecting rods can be used to surround the side of the scaffold, so that it has the functions of support and enclosure. Moreover, it can also divide the side (i.e. the inner side) close to the building between two adjacent scaffolds into several rectangular areas, so that it can meet the construction needs of ordinary people when painting, pasting tiles or passing articles. The habit of moving horizontally and up and down to reduce construction obstacles, thereby making construction smooth and improving construction efficiency. In particular, the two supporting parts are forked on the vertical rods on the same side of two adjacent scaffoldings and pressed against the upper side of the vertical rods combined with the bolts, the upper horizontal rods and the plurality of connecting rods can be used to connect the upper horizontal rods The pole is supported horizontally above, so that it can be firmly and stably assembled on the scaffold only by fastening and fastening the two fasteners on the two vertical poles respectively, so its assembly can be more convenient and fast. In addition, due to the structural design that the two ends of the plurality of connecting rods are respectively swingably combined with the upper and lower cross bars, the upper and lower cross bars can be horizontally attached to each other, so that it can thus The overall volume is greatly reduced, which facilitates transportation and storage.

Its structure is substantially the same as that of the first embodiment, except that the upper cross bar 40 of the third embodiment has a middle section 43 and two bending sections 44 . The two bent sections 44 are located at the two ends of the middle section 43 and are bent upwards, so that the two fasteners 50 are higher than the middle section 43, so that when the scaffold guardrail is assembled on the scaffold 70, the buckle The member 50 is located above the fastener 50 of the adjacent scaffolding rail with the straight upper rail 40 . Of course, in this embodiment, the two bent sections 44 can also be bent downwards, so that the two fasteners 50 are lower than the middle section 43, so that when the scaffold guardrail is assembled on the scaffold 70 , the fastener 50 is located below the fastener 50 of the adjacent scaffolding guardrail with a straight upper cross bar 40 (not shown in the figure).

When the scaffold guardrail of the present invention is assembled on the scaffold 70, it can be surrounded by the lower cross bar 20, the upper cross bar 40 and the two connecting rods 60 on the side of the scaffold 70, so that it has support and enclosure effect. Moreover, it can also be divided into several rectangular areas between two adjacent scaffoldings 70 near one side of the building (i.e., the inner side), so that it can meet the requirements of ordinary people when painting, sticking tiles or passing articles. The habit of moving horizontally and up and down is required to reduce construction obstacles, thereby enabling smoother construction and improving construction efficiency. In particular, the two supports 30 are forked on the same side poles 71 of two adjacent scaffolds 70, and pressed against the upper side of the poles 71 combined with the bolts 72, the lower cross bar 20 and the two The connecting rod 60 supports the upper cross bar 40 above the lower cross bar 20, so that it only needs to use the two fasteners 50 to fasten and fasten the two vertical bars 71 respectively to make it firm and stable. Assembled on the scaffold 70, so its assembly can be more convenient and fast. In addition, due to the structural design that the two ends of the two connecting rods 60 are respectively swingably combined with the upper cross bar 40 and the lower cross bar 20, the upper and lower cross bars 40, 20 can be moved horizontally. Close to each other, so that the overall volume can be greatly reduced, which is convenient for transportation and storage (as shown in Figure 7).
