Abstract

The utility model relates to a hanging insertion type steel pipe scaffold, which has simple and handy structure and good load-bearing performance and is rapid and convenient for assembly and disassembly. The hanging insertion type steel pipe scaffold comprises upright posts, U-shaped bases, a crossbeam, hanging elements, and bolts. Two pairs of U-shaped bases are welded in the axial direction of the upright posts at an interval in a staggered manner, each pair of the U-shaped bases are symmetrically welded on the upright posts as the insertion bases connected with the crossbeam, U-shaped base holes are arranged in the axial direction of the upright posts, and the two pairs of the U-shaped bases form an included angle of 90 degrees. The hanging elements are respectively welded at the two ends of the crossbeam and are connected with the U-shaped bases in a hanging insertion manner, and slotted holes matched with bolts are formed on the hanging elements. The hanging elements are lug-shaped hanger type hanging elements made of a steel plate, a horizontal slotted hole matched with the bolt is arranged on both the upper end surface and the lower end surface of the hanging element, the bolts pass through the slotted holes on the hanging elements, and a stop for preventing the bolts from sliding out is riveted at the tail end of each bolt. The scaffold can be assembled by lifting the bolts in the hanging elements, hanging the hanging elements at the two ends of the crossbeam into the U-shaped bases of the upright posts, and inserting the bolts.

Description

Hang and insert the formula steel pipe scaffold

Technical field

The utility model belongs to building operations component technology field, particularly a kind of steel pipe scaffold.

Background technology

Have in the steel pipe scaffold that uses at present, " flower type spigot-and-socket steel pipe scaffold " (patent No. CN96212335.8), it to the effect that, " it is mainly by flower type seat; socket joint head; montant; cross bar; brace etc. are partly formed; flower type cover for seat is contained on the montant and welds dead by certain step pitch, the socket joint head is welded on the two ends of cross bar by certain advance, rotary connector is riveted on two of brace by certain oblique distance, wear fourth and pass riveter behind the fourth hole, be respectively equipped with the socket joint notch on socket joint head and the rotary connector, wear the fourth hole, flower type seat is provided with the socket joint key, and socket joint key and socket joint notch are the activity tight fit.”

The deficiency of this steel pipe scaffold is: slotting formula steel pipe scaffold structure compared part weight is bigger with hanging, and the socket joint key is lost easily.

(patent No. 89218873) it to the effect that as " bowl type spigot-and-socket steel pipe scaffold " for another kind of steel pipe scaffold, " adjustable seats is arranged; vertical rod; cross bar; brace and scaffold floor; attached members such as tripod railing; connect with short tube between the vertical rod, in vertical rod, be provided with by following bowl, spacer pin reaches goes up the fixing bowl joint that bowl is formed, but any direction connects four cross bars or brace on every group of bowl joint, movable bowl button is arranged, it can be a bolt type. also can be they of Wedge-type all have two and half bowls, connect together with bolt, the bolt that is connected in addition on half bowl of bolt type reaches nut engaged with it, Wedge-type the bearing pin that is connected on half bowl arranged, sloping packing ring and voussoir cooperate with it, and this activity bowl button can be installed in any part in the vertical rod.”

The deficiency of this steel pipe scaffold is: insert complexity of formula steel pipe scaffold structure compared with extension.

The utility model content

The utility model purpose is on existing scaffolding structure basis, provides a kind of simple and light, and the extension of fast assembling and disassembling is inserted the formula steel pipe scaffold.

The extension that the utility model provides is inserted the formula steel pipe scaffold, mainly comprise column, U type seat, crossbeam, suspension member, latch, along two pairs of U type seats of the staggered welding of column axially spaced-apart certain distance, every pair of U type seat is symmetrically welded on the column, as the socket that connects with crossbeam, U type seat hole is axial along column, and the angle between the two pairs of U type seats is 90 °.The crossbeam two ends respectively are welded with a suspension member, and this suspension member is the extension formula of inserting with U type seat and connects, and has the slotted hole that cooperates with latch on the suspension member.

The suspension member at described crossbeam two ends is ear shape coupling type suspension members made from steel plate, respectively has a horizontal slotted hole that cooperates with latch on the suspension member upper and lower end face.The latch that is used to lock scaffold passes the slotted hole on the suspension member, and the terminal riveted joint of latch has a backstop that prevents that latch from skidding off.

When scaffold is installed, the latch in the suspension member is mentioned along slotted eye, the suspension member at two ends on the crossbeam is hung in the U type seat on the column, again latch is inserted, insert and finish installation process once hanging one.The slotted eye of latch and upper end is the activity tight fit.All the other positions connect, and all so operation gets final product.

During dismounting, as long as latch is extracted, column can separate with crossbeam, realizes simple and efficient.

Advantage of the present utility model and good effect:

The utility model belongs to the light scaffold structure, and simpler with existing all kinds of steel pipe scaffold structure compared, weight is lighter, and load-carrying properties are good, the installing/dismounting more convenient and quicker, and labour intensity is littler, helps improving work efficiency.And can overcome the phenomenon that some spigot-and-socket steel pipe scaffolds exist plug-in unit to lose.It is comparatively desirable light steel tube scaffolding structure.

The specific embodiment

Embodiment 1:

Figure 1 shows that the slotting formula steel pipe scaffold of extension a kind of simple and light, fast assembling and disassembling that the utility model provides, mainly comprise column 1 and crossbeam 3, along two pairs of U type seats 2 of the staggered welding of column axially spaced-apart certain distance, U type seat is as the socket that connects with crossbeam, every pair of U type seat is symmetrically welded on the column (sees Fig. 2 and Fig. 3), U type seat hole is axial along column, and the angle between the two pairs of U type seats is 90 °.A suspension member 4 is respectively welded at the crossbeam two ends, and this suspension member is the extension formula of inserting with U type seat and connects, and has the slotted hole that cooperates with latch 5 (seeing Fig. 6 and Fig. 7) on the suspension member.

The suspension member at described crossbeam two ends is ear shape coupling type suspension members made from steel plate, respectively has a horizontal slotted hole that cooperates with latch (seeing Fig. 4 and Fig. 5) on the suspension member upper and lower end face, wherein, and following slotted hole broad.During assembling, at first latch 5 is inserted from the last slotted hole of suspension member, pass down behind the slotted hole and prevent that one of the terminal riveted joint of latch latch from skidding off the backstop 6 of slotted hole, the length of backstop 6 is between the width of upper and lower slotted hole.Latch 5 is the activity tight fit with the slotted hole of suspension member.

When scaffold is installed, the latch in the suspension member is mentioned along slotted hole, the suspension member at two ends on the crossbeam is hung in the U type seat on the column, latch is inserted again, one hangs one inserts and can finish installation process.All the other positions connect, and all so operation gets final product.

During dismounting, as long as latch is extracted, column can separate with crossbeam, and is simple and efficient.
