Description
Technical field
The present invention relates to a kind of construction techniques, in particular, relate to construction method of installation after a kind of terrace heavy steel plate built-in fitting.
Background technology
The construction method that in building engineering construction, pre-embedded steel slab is conventional is first welding embedded element fixed mount, relocates the fixing embedded part of installation, last casting concrete molding.Industrial Plant Ground large area pre-embedded steel slab embedded part adopts this method construction, it may appear that in concreting process, blanking has some setbacks, and reduces efficiency of construction；Vibrating in construction insufficient, concrete water bleeding shrinks all can cause pre-embedded steel slab large area hollowing；Lower ash hole offer, repair welding time pre-embedded steel slab can be caused to deform, readjust and need to waste time and energy；Embedded part steel plate off normal can be caused in casting process to adjust difficulty, and revising or doing over again needs to expend a large amount of manpower and materials, and quality is difficult to ensure.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide concreting convenience, vibration compacting, raising efficiency of construction, avoid embedded part large area hollowing to occur a kind of terrace heavy steel plate built-in fitting after construction method of installation.
Construction method of installation after a kind of terrace heavy steel plate built-in fitting of the present invention, comprises the steps:
A, according to drawing requirement installing bottom layer reinforced mesh, use angle steel vertically to anchor into below terrace, anchor into the degree of depth not less than 500mm, be welded and fixed support；
B, according to the specification of pre-embedded steel slab and steel plate raw material measure, four corners of pre-embedded steel slab offer hole, location, and the centrage both sides of pre-embedded steel slab length direction respectively offer that an injected hole, described pre-embedded steel slab and anchoring claw are fixing to be connected；
C, according to pre-embedded steel slab position of center line measurement and positioning, the essence whole bolt of Heibei provincial opera and adjusting nut are installed in the position corresponding with hole, location at independent fixed support, adjusting pre-embedded steel slab essence to put down, after passed examination, casting concrete is to higher than adjusting nut upper end 2-4mm vibration compacting；
Complete the installation of pre-embedded steel slab before D, concrete initial set, and adjust absolute altitude, flatness, after passed examination, whole for essence Heibei provincial opera bolt is fixed with location hole spot welding, then pre-embedded steel slab periphery concrete floor filling-in and be compacted receive light and maintenance；
E, slip casting funnel fill grouting material is installed at injected hole, fills compensating concrete bleeding by the grouting material that flows automatically with grouting material, utilizes from close performance and shrink gap, it is to avoid embedded part large area hollowing occurs；
Described fixed support is independent rack.4 hoisting rings are installed on described pre-embedded steel slab.Perfusion for the shrinkage-free grouting material of high intensity in described injected hole.Described pre-embedded steel slab blanking uses mechanical shearing or plasma cutting, it is to avoid hot-working produces steel plate deformed.The centrage of said two injected hole distance pre-embedded steel slab length direction is all 500mm.A diameter of 30 mm of described injected hole 4.Described location bore dia is 20mm.
The invention has the beneficial effects as follows: (1) concreting is convenient, vibration compacting can improve efficiency of construction；(2) deviation is found after pre-embedded steel slab is installed, can be flat with adjusting bolt essence in time, it is ensured that construction flatness；(3) irrigating high strength grout by injected hole, by flowing automatically with grouting material, utilizing, grouting material shrinks gap from close performance compensation concrete water bleeding, and embedded part large area hollowing can be avoided to occur；(4) pre-embedded steel slab is not required to offer, ash vibrates hole under repair welding, it is to avoid Plate Welding temperature distortion；(5) pre-embedded steel slab integral installation improves bearing capacity, it is ensured that quality, cost-effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: pre-embedded steel slab 1, anchoring claw 2, hole 3, location, injected hole 4, slip casting funnel 5, hoisting ring 6, the essence whole bolt of Heibei provincial opera 7, fixed support 8.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Construction method of installation after a kind of terrace heavy steel plate built-in fitting of the present invention, comprises the steps:
A, according to drawing requirement installing bottom layer reinforced mesh, use angle steel vertically to anchor into below terrace, anchor into the degree of depth not less than 500mm, be welded and fixed support 8, fixed support 8 is independent rack；
B, according to the specification of pre-embedded steel slab 1 and steel plate raw material measure, pre-embedded steel slab 1 blanking uses mechanical shearing or plasma cutting, hot-working is avoided to produce steel plate deformed, four corners of pre-embedded steel slab 1 offer the hole, location 3 of a diameter of 20mm, the injected hole 4 of a diameter 30mm is respectively offered on the centrage both sides of pre-embedded steel slab 1 length direction, injected hole 4 is 500mm apart from the centrage of pre-embedded steel slab 1 length direction, described pre-embedded steel slab 1 and the fixing connection of anchoring claw 2, install 4 hoisting rings 6 after pre-embedded steel slab 1 completes；
C, according to pre-embedded steel slab 1 position of center line measurement and positioning, the essence whole bolt of Heibei provincial opera 7 and adjusting nut are installed in the position corresponding with hole 3, location at independent fixed support 8, adjusting pre-embedded steel slab 1 essence flat, after passed examination, casting concrete 9 is to higher than adjusting nut upper end about 3mm vibration compacting；
Complete the installation of pre-embedded steel slab 1 before D, concrete 9 initial set, and adjust absolute altitude, flatness, after passed examination, whole for essence Heibei provincial opera bolt 7 is fixed with location hole 3 spot welding, then pre-embedded steel slab 1 periphery concrete 9 terrace filling-in and be compacted receive light and maintenance；
E, slip casting funnel 5 fill the shrinkage-free grouting material of high intensity is installed at injected hole 4, fills compensating concrete bleeding by the grouting material that flows automatically with grouting material, utilizes from close performance and shrink gap, it is to avoid embedded part large area hollowing occurs.
Described step A is fixed independent rack and is used angle steel welding, and frame bottom anchors into formation independent system in the following soil layer of terrace, the cradle top welding scalable whole bolt of essence Heibei provincial opera 7, and puts down whole for essence Heibei provincial opera bolt 7 essence to pre-embedded steel slab 1 bottom position.
Described step B pre-embedded steel slab can carry out blanking according to embedded part size or convenient size of installing, and stagger reinforced mesh position welding embedded element anchoring claw 2, offers hole 3, location and injected hole 4.
Described step C, D pour terrace concrete, complete pre-embedded steel slab and install after abundant vibration compacting before concrete initial set, and carry out checking to the flatness of pre-embedded steel slab 1, horizontal level and adjust, qualified after adjustments bolt is fixed with positioning hole spot welding.
Described step E installs slip casting funnel 5 on pre-embedded steel slab 1 injected hole 4, and fills high intensity contraction-free grouting concrete.
