Abstract

The utility model relates to a lightweight movable telescoping steel form which mainly comprises a travelling chassis, a bearing scaffold, an arch and a formwork. A travelling portion of the travelling chassis comprises two wheel sets, a chassis and a moving platform. The two wheel sets are disposed at two ends of the chassis respectively. The moving platform is arranged on the chassis. The arch is an arc structural frame made of steel tubes and comprises a top arch and two side arches. The side arches are hinged to the top arch. The formwork comprises side forms and a top form. The bearing scaffold is disposed on the chassis. The top arch is disposed above the bearing scaffold. The two side arches are disposed on two sides of the bearing scaffold. The side forms and the top forms are fixed on the arch. The lightweight movable telescoping steel form is low in manufacturing cost, reliable in performance, simple to use, convenient to operate, and fast to mount. The lightweight movable telescoping steel form is more economical and applicable to concreting of single holes and tunnels, which are smaller than 9m in diameter and smaller than 400m in length.

Description

A kind of lightweight mobile steel form carrier

Technical field

The utility model relates to the water power construction engineering technical field; Specifically be to be used for engineerings such as water conservancy, water power, municipal administration; Hole footpath below 9m, the underground chamber below the concrete lining thickness 1.3m, when secretly containing the concrete lining cutting, the lightweight mobile steel form carrier that typified form is processed voluntarily.

Background technology

As everyone knows, when water conservancy, water power, municipal diversion, water delivery engineering concrete lining construction, selecting for use of template is most important, influences very big to duration, construction costs, construction cost.Conventional method was to select higher steel form carrier of financial cost or the higher framed bent job practices of running cost for use in the past; Because similar considerably less of fabric structure size; The steel form carrier of every customization is difficult in Other Engineering and uses; Chassis transshipment charge and improvement expenses are very high simultaneously, and the secondary utilization rate is very low, and cost performance is not high aspect footpath, medium and small hole.

Summary of the invention

The purpose of the utility model is the deficiency to prior art; A kind of new lightweight mobile steel form carrier device is provided; This cost is low, dependable performance, use is simple, easy to operate, installation rate is fast, and manufacturing materials can all be had enough to meet the need and recycled basically once more; Accelerating construction progress reduces construction cost.

The purpose of the utility model is achieved through following technical scheme.

The lightweight mobile steel form carrier mainly divides four parts to form: walking chassis, load-bearing scaffold, bow member, template are formed; The walking chassis is made up of two wheels, chassis and the mobile platform of running gear, and the two-wheeled group is loaded on the two ends, chassis respectively, and mobile platform is on the chassis; Bow member is the arcuate structure frame of steel pipe manufacturing, and bow member is made up of 1 crown and 2 limit arches, and the limit arch is hinged with crown; Template is Bian Mo and backform; The load-bearing scaffold is loaded on the chassis, and the crown bow member places load-bearing scaffold top, and both sides arch bow member places load-bearing scaffold both sides, and Bian Mo and backform template are fixed on the bow member.

The utility model is to the deficiency of prior art; Through concentrating on studies, the performance of comprehensive traditional steel form carrier, principle and characteristics are developed a kind of novel lightweight mobile steel form carrier; Solved well that tunnel hole footpath is less, construction space is little, under the restricted situation of work plane; Give full play to its construction speed and reach the low superiority condition of construction cost soon, reach high efficiency, the low purpose that drops into simultaneously, and manufacturing materials can be had enough to meet the need once more all and recycled basically; Realized saving energy and reduce the cost, facts have proved that effect is good.The utlity model has following advantage with respect to prior art:

1, low, the dependable performance of this apparatus cost, use is simple, easy to operate, installation rate is fast, manufacturing materials can all be had enough to meet the need and recycled basically once more.

2, processing and fabricating and dismounting time weak point, technology is easy, and the constructor is easy to grasp.

3, the lightweight mobile steel form carrier is superior to steel form carrier from technical indicator, economic indicator.To hole footpath less than below the 9m, length builds more economical, suitable less than 400m single hole, hole.

Among the figure, 1-(walking) chassis, 2-wheels, 3-mobile platform, 4-crown bow member, 5-limit arch bow member; Holder that 6-is adjustable support, 7-load-bearing scaffold, 8-connector, 9-template, 10-channel-section steel; The 11-bearing, the 12-wheel shaft, the 13-steel wheel, the 14-i iron, the 15-i iron connects; Arch at the bottom of the 16-, 17-vertical rod, 18-cross bar, 19-diagonal brace, 20-free bearing.

The specific embodiment

As shown in Figure 1, the lightweight mobile steel form carrier of the utility model is made up of walking chassis, load-bearing scaffold 7,

bow member

4,5, template 9 etc.The load-bearing scaffold is loaded on the chassis, and the crown bow member places load-bearing scaffold top, and both sides arch bow member places load-bearing scaffold both sides, and Bian Mo and backform template are fixed on the bow member.

Wherein:

Walking chassis 1 is made up of two wheels 2, chassis 1 and the mobile platform 3 of running gear, and the two-wheeled group is loaded on the two ends, chassis respectively, and mobile platform is on the chassis.The wheel shaft of running gear wheels is not less than φ 95, and 6 steel wheels are arranged, and wheel bearing is 7519 types, leans on light-duty hoist engine to draw walking voluntarily.Structure division divides two sections (6m/ sections) to weld with channel-section steel, carries out assembly unit again after each section welding is accomplished.After making, wheels transport to the building site and the chassis welds together.Bearing frame is promptly set up on top, chassis after accomplishing with wheel assembly welding in the chassis.

Load-bearing scaffold 7 is criss-cross arranged by φ 48 steel pipes, and 17 spacings of vertical rod are 80cm, establishes diagonal brace 19 in the middle of the crisscross steel pipe; Bow member is the arcuate structure frame of steel pipe manufacturing, and bow member is made up of 1 crown and 2 limit arches, and the limit arch is hinged with crown; Template is Bian Mo and backform.After chassis installation, welding are accomplished, adopt φ 32 screw-thread steels of long 50cm, vertically be welded on the chassis 1, with fixedly vertical rod.Set up crown bow member 4 on load-bearing scaffold top, and be fixed in the above template 9.Limit mould, backform template adopt the little punching block of P3015, and limit mould, backform all are fixed on the bow member.

Crown bow member 4 connects to form through free bearing 20 with both sides arch bow member 5.For realizing freely stretching of crown bow member, the distance between bow member and load-bearing scaffold is about 50cm; The adjustable holder support 6 of configuration on every vertical rod 17 and cross bar 18 is used to regulate distance and support, the reinforcing bow member of bow member and load-bearing scaffold.

The lightweight mobile steel form carrier is superior to steel form carrier from technical indicator, economic indicator.The actual input of one cover steel form carrier is about 990,000 yuan, and the stand is gone into every side's concrete cost and is about 11 yuan; Make the actual input of light-duty chassis by oneself and be about 310,000, the stand is gone into every side's concrete cost and is about 6.9 yuan.This shows, only use the amortization aspect, make light-duty steel form carrier by oneself and account for and have great advantage from template.To hole footpath less than below the 9m, length builds more economical, suitable less than 400m single hole, hole.
