Embodiment 1

[0033] The present invention relates to a rigid diagonally-stayed member of a turnbuckle bolt and a construction method for its roof overhanging eaves support system, the steps of which are as follows:

[0034] The first step is to arrange and position the base;

[0035] The second step is to set up the support frame;

[0036] The third step is to install the turnbuckle diagonal stay member;

[0037] The fourth step, beam formwork installation;

[0038] The fifth step is to check and strengthen the frame;

[0039] The sixth step, concrete pouring;

[0040] The seventh step is to remove the formwork and support frame.

[0041] Further, the construction method of the turnbuckle rigid diagonally-stayed member and its roof overhanging eaves support system of the present invention,

[0042] Step one is as follows:

[0043] Set the cantilevered I-steel at the height of the building as the base of the roof eaves support frame. When setting, use the tower crane to lift the canti...

Embodiment 2

[0061] The first step is base installation and pole positioning;

[0062] No. 18 I-beam cantilever is set at the high place as the base of the roof overhanging eaves support frame. Diagonal tie rod; a single I-beam is 6m long and weighs 144.8Kg. Use a tower crane to lift it slowly and insert it into the anchoring steel bar pressure ring. After adjusting the position, use a wedge-shaped wooden stopper to clamp it, and nail a large nail to clamp the steel bar pressure ring. Three rows of upright poles are considered in the middle of the overhanging eaves support frame, with a spacing of 0.9m; two rows of upright poles are not considered on both sides and east and west, and the spacing is 1.1m; Φ25 is welded from the outer end of the cantilevered I-beam at 100mm, and the length is not less than 80mm. Rebar head.

[0063] The second step is to erect the outer support frame;

Abstract

The invention discloses a turnbuckle rigidity cable stayed rod piece and a roof face long cornice support system construction method thereof. the method comprises the first step of adjusting and positioning a base; the second step of erecting a support frame; the third step of installing the turnbuckle cable stayed rod piece; the fourth step of installing a beam template; the fifth step of examining and reinforcing a frame body; the sixth step of pouring concrete; and the seventh step of detaching the template and the support frame. According to the turnbuckle rigidity cable stayed rod piece and the roof face long cornice support system, construction method thereof application is simple and overhaul is convenient , a connection rod piece is in a stress state by adjusting the turnbuckle, the safety factor is high, the problem that the a cantilever scaffold and other frame bodies cannot meet the cable stayed requirement on account of the flexible cable stayed condition is solved, the purpose that round steel is in a expected press is achieved, construction is rapid, the efficiency is high, and the construction period is shortened. Machining is rapid, and cost is reduced.

Description

technical field [0001] The invention relates to a construction method of a building overhanging eaves support system, in particular to a construction method of a turnbuckle rigid diagonally-stayed member and a large overhanging eaves support system on a roof. Background technique [0002] In the process of on-site construction, the external scaffolding plays an important role, playing the dual role of surrounding enclosure and external operation construction. The external scaffolding project is a major item with great safety hazards, ensuring the safety of the external scaffolding during construction and use. It is undoubtedly the top priority in the construction process of the project. When the top roof is divided into large overhanging eaves, the support effect of the traditional cantilevered scaffolding is poor. The overweight support frame causes the lower supporting load to be too large, posing safety hazards, which cannot meet the construction requirements of the upper...
