Abstract
The invention discloses a construction method of a crack resistant structure of the root of an independent steel column for a large-area concrete ground. The construction method comprises the following steps of: fixing a main body steel column 5 on an independent concrete foundation 1 pre-embedded with a connector 4, erecting a template 6 on the periphery of the independent concrete foundation around the root of the main body steel column 5, pouring concrete 7 into the template, and removing the template when the strength of concrete in the template meets the requirement; installing a polystyrene board or bitumen linoleum 12 on the outer surface of a concrete pier from which the template is removed; constructing a first concrete ground 9, removing a part of the polystyrene board or bitumen linoleum to form a crack 11 after the strength of the first concrete ground reaches the design strength, and filling epoxy resin in the crack. The construction method is simple, and the concrete ground positioned on the independent concrete foundation around the root of the steel column is fully disconnected with the concrete grounds of buildings at other places, so that the cracking of the large-area building concrete ground caused by uneven settlement can be effectively controlled.
Description
Technical field
The invention belongs to the realm of building construction.Be specifically related to a kind of large area concrete terrace independence steel column root cracking resistance construction method.
Background technology
In large-scale steel structure building, foundation structure (see figure 1) adopts independent concrete foundation 1+ concrete straining beam 2 structures conventionally, between each independent concrete foundation, concrete straining beam is set that is:, and independent concrete foundation is connected into integral body.Place 3 backfills that independent concrete foundation and concrete straining beam surround, the native absolute altitude to designing requirement of compacting element.After the upper body Steel Structure Installation of independent concrete foundation completes, carry out building first floor concrete terrace construction.
When the first floor concrete floor area of building is larger; the rigidity of the local ground surrounding due to independent concrete foundation 1 and the residing position of concrete straining beam 2 and they is inconsistent; building often there will be differential settlement distortion; cause first floor concrete floor cracking; thereby affect the attractive in appearance of concrete floor, even arrive and affect building itself.For fear of this phenomenon, the way of now often taking is: main body steel column (5) is fixed in the independent concrete foundation (1) that is embedded with connector (4), carry out first floor concrete floor (9) construction, after having constructed, on the concrete floor of surrounding that is positioned at independent concrete foundation, cut off the gap that the degree of depth is 1/3 ground face thickness downwards, induction seam (10) as differential settlement, causes damage (Fig. 2) to reduce differential settlement of buildings to terrace.The weak point of this method is to cut off operation to be not easy, and cuts off the degree of depth wayward, when differential settlement value is larger, and cuts off the degree of depth of induction seam and still can cause the damage of terrace when dark not.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of large area concrete terrace independence steel column root cracking resistance construction method is provided.
Technical scheme of the present invention is summarized as follows:
Large area concrete terrace independence steel column root cracking resistance construction method, comprises the steps:
Main body steel column 5 is fixed in the independent concrete foundation 1 that is embedded with connector 4, in the surrounding of main body steel column 5 roots, be positioned at independent concrete foundation neighboring part and install template 6, the thickness of layer concrete terrace headed by the height of template; To concreting 7 in template, the stripping when concrete strength in template reaches requirement; And at the external surface of the vertical level of the concrete pier of stripping, polyphenyl plate or pitch prill malthoid 12 are set; Carry out again first floor concrete floor 9 construction, when the intensity of first floor concrete floor reaches after design strength, at polyphenyl plate or pitch prill malthoid place, reject 10-20mm downwards and form gap 11, and by epoxy resin cementation of fissures gap.
Construction method of the present invention is simple, the concrete floor that steel column root is positioned to the concrete floor of independent concrete foundation and the building at other position around disconnects completely, can effectively control the cracking that large area building concrete terrace causes due to differential settlement.

The specific embodiment
Below in conjunction with concrete accompanying drawing, the present invention is further illustrated.
Large area concrete terrace independence steel column root cracking resistance construction method (seeing Fig. 3,4 and 5), comprises the steps:
Main body steel column 5 is fixed in the independent concrete foundation 1 that is embedded with connector 4, in the surrounding of main body steel column 5 roots, be positioned at independent concrete foundation neighboring part and install template 6, the thickness of layer concrete terrace headed by the height of template; To concreting 7 in template, the stripping when concrete strength in template reaches requirement; And at the external surface of the vertical level of the concrete pier of stripping, polyphenyl plate or pitch prill malthoid 12 are set; Carry out again first floor concrete floor 9 construction, when the intensity of first floor concrete floor reaches after design strength, at polyphenyl plate or pitch prill malthoid place, reject 10-20mm downwards and form gap 11, and by epoxy resin cementation of fissures gap.
Claims (1)
1. large area concrete terrace independence steel column root cracking resistance construction method, it is characterized in that comprising the steps: main body steel column (5) is fixed in the independent concrete foundation (1) that is embedded with connector (4), in the surrounding of main body steel column (5) root, be positioned at independent concrete foundation neighboring part and install template (6), the thickness of layer concrete terrace headed by the height of template; To concreting (7) in template, the stripping when concrete strength in template reaches requirement; And at the external surface of the vertical level of the concrete pier of stripping, polyphenyl plate or pitch prill malthoid (12) are set; Carry out again first floor concrete floor (9) construction, when the intensity of first floor concrete floor reaches after design strength, at polyphenyl plate or pitch prill malthoid place, reject 10-20mm downwards and form gap (11), and by epoxy resin cementation of fissures gap.
