Description

The hanging method of apical ring in dome structure installation

Technical field

The present invention relates to a kind of mounting method of dome structure, especially relate to the hanging method of apical ring in dome structure installation.

Background technology

At present, when known dome structure is installed apical ring hoisting process in stable being difficult to of apical ring ensure, and to dock with the steel pipe of lower edge on assembled component main steel frame due to apical ring, when apical ring is located, easily to occur the phenomenon that precision is inadequate.

Summary of the invention

In order to overcome the deficiency being difficult to ensure that its stable precision with occurring during apical ring location is inadequate occurred in the hoisting process of apical ring when dome structure is installed, the invention provides a kind of hanging method of apical ring, lifting to apical ring when the method can not only meet conventional mounting, and the stable of apical ring in installation process can be ensured, and with enough precision, apical ring can be located.

In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is: the hanging method of apical ring in a kind of dome structure installation, its step taked is as described below.

Temporary steel support due to apical ring is the important support component of whole rack steel work, and the weight and assembled component of bearing apical ring are installed the construction weight of front 1/2 at base ring by temporary steel support.In order to ensure the stable of apical ring and apical ring jacking and unloading, the positioning and guiding pipe of 4 Φ 140 × 5 is set, to ensure the guiding of apical ring when jacking and assembled component are installed, location and to stablize at the top of temporary steel support.The jackscrew of 4 32t is set simultaneously to reach the effect of jacking and unloading.Arrange 4 groups simultaneously and support adjustment backing plate, often group regulates backing plate by each l block of the cushion block of l00mm, 50mm and 20mm, 16mm, 12mm, l0mm, 8mm, 6mm, each one piece of outfit of steel plate of 4mm, always regulates highly 200mm.Backing plate is regulated to be placed in the apical support apical ring of temporary steel support and the load of apical ring carrying, when apical ring jacking to design elevation, adjust to level, middle zenith Ring current distribution and angle to timing, all backing plates of backing plate group and temporary steel support is regulated to weld, and form an entirety with temporary steel support, ensure stablizing when assembled component lifts.

Before apical ring is in place, the wire rope arranging 4 Φ 16mm (6 × 37+1) at 4 angle points of temporary steel support makes stablize the cable rope of temporary steel support, and every root cable rope configures the jack of l platform 2t as take-up device.

According to the classification model of the weight of apical ring, maximum gauge, body height and setting height(from bottom) determination crane.Because apical ring docks with the steel pipe of lower edge on assembled component main steel frame.Therefore, the location of apical ring is very important, and lifting and the location of apical ring must complete simultaneously.The location of apical ring can have been come by following four steps.

(1) location, direction of sky apical ring in: adopt transit to position with axis, axis projected the installation site of middle sky apical ring and make marks, so that align when apical ring is in place.

(2) centralized positioning of apical ring: adopt total powerstation with axis location, axis is projected now mounted equipment top making marks, recycle at 4 and do the central point that lower end determined by cross wire, in bottom middle sky apical ring, spot welding one annulus hangs thin steel wire, and the intersection point of the lower end and cross hairs that adopt the weight of 20Kg to hang over steel wire overlaps and determines to push up Ring current distribution.

(3) horizontal location of apical ring: first by levelling for 4 of falsework top pieces of top board level gauges, simultaneously by levelling for the support baseboard of 4 32t jackscrew, 4 groups support adjustment backing plate and adopt mutually level steel plate to ensure the levelness that apical ring is installed.

(4) elevation location of apical ring: adopt level gauge to provide horizontal elevation point at 4 suspension column places of falsework, then with drawing horizontal method steel disk chi to measure.

The invention has the beneficial effects as follows: not only can ensure the stable of apical ring hoisting process, and precision when can ensure that apical ring is located.

Detailed description of the invention

Select suitable crane and suspender, guarantee that the mechanical performance of crane meets the requirement of lifting.

The temporary steel support of apical ring is the important support component of whole rack steel work, and the weight and assembled component of bearing apical ring are installed the construction weight of front 1/2 at base ring by temporary steel support.

In order to ensure the stable of apical ring and apical ring jacking and unloading, the positioning and guiding pipe of 4 Φ 140 × 5 is set, to ensure the guiding of apical ring when jacking and assembled component are installed, location and to stablize at the top of temporary steel support.The jackscrew of 4 32t is set simultaneously to reach the effect of jacking and unloading.Arrange 4 groups simultaneously and support adjustment backing plate, often group regulates backing plate by each l block of the cushion block of l00mm, 50mm and 20mm, 16mm, 12mm, l0mm, 8mm, 6mm, each one piece of outfit of steel plate of 4mm, always regulates highly 200mm.Backing plate is regulated to be placed in the apical support apical ring of temporary steel support and the load of apical ring carrying, when apical ring jacking to design elevation, adjust to level, middle zenith Ring current distribution and angle to timing, all backing plates of backing plate group and temporary steel support is regulated to weld, and form an entirety with temporary steel support, ensure stablizing when assembled component lifts.

Before apical ring is in place, the wire rope arranging 4 Φ 16mm (6 × 37+1) at 4 angle points of temporary steel support makes stablize the cable rope of temporary steel support, and every root cable rope configures the jack of l platform 2t as take-up device.

According to the classification model of the weight of apical ring, maximum gauge, body height and setting height(from bottom) determination crane.[0019] apical ring docks with the steel pipe of lower edge on assembled component main steel frame.Apical ring lifting time apical ring lifting and location must complete simultaneously.

The location, direction of middle sky apical ring: adopt transit to position with axis, axis projected the installation site of middle sky apical ring and make marks, so that align when apical ring is in place.

The centralized positioning of apical ring: adopt total powerstation with axis location, axis is projected now mounted equipment top making marks, recycle at 4 and do the central point that lower end determined by cross wire, in bottom middle sky apical ring, spot welding one annulus hangs thin steel wire, and the intersection point of the lower end and cross hairs that adopt the weight of 20Kg to hang over steel wire overlaps and determines to push up Ring current distribution.

The horizontal location of apical ring: first by levelling for 4 of falsework top pieces of top board level gauges, simultaneously by levelling for the support baseboard of 4 32t jackscrew, 4 groups support adjustment backing plate and adopt mutually level steel plate to ensure the levelness that apical ring is installed.

The elevation location of apical ring: adopt level gauge to provide horizontal elevation point at 4 suspension column places of falsework, then with drawing horizontal method steel disk chi to measure.

Such scheme industry technician can be realized by industry technology means.
