Abstract
The utility model discloses a device for preventing a welded spherical latticed shell from falling and regulating the elevation. The device consists of two supporting legs, a supporting beam and a jack, wherein the supporting beam is fixedly connected to the two supporting legs; and the jack is placed on the supporting beam. The device is simple in structure and convenient to use. After being lifted once, a member can be supported, a phenomenon that the member continuously slides downwards is avoided, and simultaneously, the elevation of the latticed shell which is not put in place can be accurately regulated.
Description
Technical field:
The utility model belongs to a kind of steel building erection equipment, and is particularly a kind of for the anti-fall device of adjusting with absolute altitude of welding net shell.
Background technology:
Over nearly 10 years, development along with Building Trade in China, steel building is more and more higher, scale and span is increasing, moulding also becomes increasingly complex, the latticed shell structure of China is also used many gradually in various buildings, the scope of application is also more and more wider, especially in large span and large spatial structure, usually can see especially this space structures of spherical net brace.In job practices, the various method for improving such as large span latticed shell structure hydraulic pressure CONTROLLED INTEGRAL LIFT TECHNOLOGY, solder ball net shell roofing lift technique are used frequently especially.In various method for improving, for the temporary fixed drawn game standard laid down by the ministries or commissions of the Central Government height adjustment of net shell in lifting process progressively there are no good method, and after the net shell once promotes, the forced locking device of lifting means is always just understood the approach locking state, the in place and lower very large trouble that causes to operation of giving the net shell at the naturally descending 10mm of steel strand of lifting weight behind 20mm.Therefore, just need after complete a kind ofly can support the member that promotes once promoting, and stop member to continue to slide downwards, the absolute altitude before can also be in place to the net shell carry out the device of accurate adjustment.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and providing a kind of for the anti-fall device of adjusting with absolute altitude of welding net shell, this device can be finished the front absolute altitude adjustment in place of net shell temporary fixed anti-fall and net shell of net shell in lifting process.
As above design, the technical solution of the utility model is: a kind of for the anti-fall device of adjusting with absolute altitude of welding net shell, it is characterized in that: formed by two supporting legs, brace summer and jack; Brace summer is fixed on the supporting leg, and jack is placed on the brace summer.
Above-mentioned supporting leg adopts bracket.
The utility model is simple in structure, easy to use.Just can support the member that promotes after complete once promoting, and stop member to continue to slide downwards, can also carry out accurate adjustment to net shell front absolute altitude in place simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in the figure: a kind of for the anti-fall device of adjusting with absolute altitude of welding net shell, formed by two support bracket N, brace summer L and jack Q. brace summer is fixed in and supports on the bracket, and jack is placed on the brace summer.
Use procedure of the present utility model is:
1, the net shell is fixing anti-fall:
1) according to load and lifting bracket spacing, determines to select specification and the length L of this device;
2) determine the absolute altitude of the bracket N that this device is installed;
3) the net shell once promote complete after, jack Q is placed under the lifting ball W, adjust the stroke of jack, make its stressed get final product, other suspension centres are all fixed with this device.(such as accompanying drawing).
2, the adjustment of net shell absolute altitude:
1) the net shell last promote complete after through measuring the absolute altitude of each hoist point net shell A;
2) with design elevation contrast after, for design elevation the absolute altitude of the lifting suspension centre D of error being arranged, Q adjusts with jack, until meet the requirements.(such as accompanying drawing).
Claims (2)
1. one kind is used for the device that welding net shell is anti-fall and absolute altitude is adjusted, and it is characterized in that: be comprised of two supporting legs, brace summer and jack; Brace summer is fixed on the supporting leg, and jack is placed on the brace summer.
2. according to claim 1 a kind of for the anti-fall device of adjusting with absolute altitude of welding net shell, it is characterized in that: above-mentioned supporting leg adopts bracket.
