Description
Technical field
The present invention relates to the construction technology of a kind of cast-in-place concrete floor or superstructure and the spring support member of employing, belong to building engineering field.
Background technology
In the present most building structure, floor (lid) pre-stress hollow precast plate and the double-layer double-direction reinforcement placement in-situ reinforced concrete slabs (lid) of adopting more, in-situ reinforced concrete slab (lid) needs site operation, namely at the scene according to design attitude, carry out formwork, assembling reinforcement, concreting, obtain floor (lid) through maintenance, form removal then.Need be on base plate be arranged before the concreting; following two-layer steel mesh reinforcement; lower floor's steel mesh reinforcement supports by cushion block; top mat supports by split heads; but at the scene in the work progress; because the constructor can walk up and down at steel mesh reinforcement; the phenomenon that often causes split heads or cushion block to skew; but nobody notes or it is propped up usually; cause; following steel mesh reinforcement can not effectively be supported; thereby on can't satisfying; the spacing of following steel mesh reinforcement and last; the designing requirement of lower protective layer thickness; when the constructor when the online work of top reinforcement is walked about or is trampled; belong to hard support owing to be used for supporting the split heads of top mat; the situation that reinforcing bar is bent into dog leg will appear; reinforcing bar can't return to initial configuration after being converted into dog leg; cause on the floor (lid); descend the serious change of the design size of two-layer steel mesh reinforcement spacing, thereby have a strong impact on the construction quality of cast-in-place concrete floor (lid).
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of can guarantee the spacing between the steel mesh reinforcement up and down and up and down protective layer thickness, prevent that top reinforcement from dog leg occurring, guaranteeing the construction technology of cast-in-place concrete floor or superstructure quality; The present invention provides the spring support member that adopts in the construction technology simultaneously.
The construction technology of cast-in-place concrete floor of the present invention or superstructure, comprise the steps: that a bottom template → arrange upper and lower double steel bar → assembling reinforcement forms steel mesh reinforcement → installations and supports the supporting member → concreting → shake of upper and lower layer steel mesh reinforcement and smash concrete → maintenance → form removal, supporting member employing spring support member.
In this floor (lid) construction technology, owing to adopt spring support member to support upper and lower two-layer steel mesh reinforcement, when the constructor when steel mesh reinforcement is walked up and down, top mat can and set back automatically to lower compression, therefore the situation that top reinforcement is bent into dog leg can not occur, thereby guarantee the quality of cast-in-place concrete floor.Wherein, spring support member has multiple form of structure, adopts following two kinds of preferred versions in this technology:
Scheme one:
Spring support member comprises supporting frame and stage clip one, supporting frame is placed on the template of bottom, the bottom of supporting frame arranges lower floor's steel bar groove, the reinforcing bar of lower floor's steel mesh reinforcement places lower floor's steel bar groove, the top of supporting frame arranges pressure spring slot, stage clip one is contained in the pressure spring slot, and the space between stage clip one top and the supporting frame top is the top reinforcement groove, and the reinforcing bar of top mat places the top reinforcement groove.
By adopting whole supporting frame to support upper and lower two-layer steel mesh reinforcement simultaneously, solved in original technology because adopting split heads, cushion block to support split heads that upper and lower steel mesh reinforcement causes or cushion block respectively and skewed and leak the muscle phenomenon, make upper and lower layer steel mesh reinforcement all can access effective support, guaranteed spacing and upper and lower protective layer thickness between the upper and lower steel mesh reinforcement; Realized the upper and lower layer of resiliency supported between the steel mesh reinforcement by stage clip one, prevented from being bent into dog leg because of the hard top reinforcement that causes that supports.
Wherein, the upper/lower terminal of stage clip one all arranges and leads hook and be installed on the supporting frame by leading hook.By leading hook, play the guiding role on the one hand, guarantee stage clip one vertically moving in pressure spring slot, can prevent that on the other hand stage clip one from popping up in reseting procedure.
Scheme two:
Spring support member is support spring, stage clip two is adopted on the top of support spring, extension spring is adopted in the bottom, stage clip two and extension spring one process, support spring is placed on the template of bottom, lower floor's steel mesh reinforcement is placed in the extension spring, connects by the stage clip two that vertically arranges between the upper and lower two-layer steel mesh reinforcement.During installation, support spring is placed on the template of bottom, then stage clip two is walked around the location, bottom that lower floor's steel mesh reinforcement is convenient to stage clip two, stage clip two tops and top mat are fixed.
Identical with scheme one; adopt one processing owing to support extension spring and the stage clip between the upper and lower two-layer steel mesh reinforcement two of lower floor's steel mesh reinforcement; therefore can guarantee spacing and upper and lower protective layer thickness between the upper and lower steel mesh reinforcement; and realized resiliency supported between the upper and lower layer steel mesh reinforcement preventing that top reinforcement is bent into dog leg by stage clip two.
The beneficial effect that the present invention compared with prior art has is:
The construction technology of this cast-in-place concrete floor or superstructure, by adopting spring support member to support upper and lower two-layer steel mesh reinforcement, when the constructor when steel mesh reinforcement is walked up and down, top mat can and set back automatically to lower compression, thereby can avoid reinforcing bar to be bent into dog leg, effectively guarantee the quality of cast-in-place concrete floor or superstructure, particularly construction quality has been played very large lifting; The spring support member reasonable in design; be convenient to batch production production; make upper and lower layer steel mesh reinforcement all can access effective support by overall structure; spacing and upper and lower protective layer thickness between the upper and lower steel mesh reinforcement have been guaranteed; and construction and installation are simple and efficient, easy to operate, are convenient to large-scale promotion application.
