Abstract
The utility model provides a connection structure for a prefabricated open column and a foundation pit. The connection structure is composed of the foundation pit, a steel bar framework and the prefabricated open column. The steel bar framework is composed of pre-buried steel bars arranged in the vertical direction and annular stirrups binding the pre-buried steel bars transversely. The prefabricated open column is hollow, and the top of the prefabricated open column is open. The prefabricated open column is arranged above the foundation pit. The steel bar framework penetrates through the portion between the hollow portion inside the prefabricated open column and the foundation pit. Reinforced steel bar nets composed of steel bars in the transverse direction and the vertical direction are respectively arranged on the top and the lower portion of the foundation pit. The portion among the foundation pit, the steel bar framework and the prefabricated open column is filled with grouting mud and fixed, and a concrete cushion layer is arranged on the bottom of the foundation pit.
Description
Technical field
The utility model relates to building trade ground foundation engineering technical field, relates in particular to the syndeton of a kind of pre-formed members post and foundation ditch.
Background technology
In industrial production, the ground foundation engineering in existing building trade is the very concerned industry field with paying attention to always, how to make solid durable foundation, is unusual important field of research.
Along with the raising of expanding economy and the requirement of people's dwelling environment, building is built higher and higher in recent years, also more and more higher for foundation construction requirements, capital faces excavation of foundation pit, excavation of foundation pit is a complicated comprehensive geotechnical engineering, and the cutting depth of foundation ditch is also more and more darker, owing to being subject to the impact of the servicing units such as foundation ditch braced structures, adopt between which kind of construction method guarantee foundation ditch and column not only easy for installation and firm and durable, and economical, energy-conservation and environmental protection, seem particularly important.
Utility model content
For above-mentioned defect of the prior art and problem, the object of the utility model embodiment is to provide a kind of pre-formed members post of better reliability and the syndeton of foundation ditch, thereby improves steadiness.
In order to achieve the above object, the utility model embodiment provides following technical scheme:
A syndeton for pre-formed members post and foundation ditch, is made up of foundation ditch, cage of reinforcement and pre-formed members post, it is characterized in that, cage of reinforcement is made up of the embedded ribs vertically arranging, the ring-shaped stirrup that laterally bundlees embedded ribs; Pre-formed members post hollow and open top, and be positioned at foundation ditch top, cage of reinforcement runs through between the cavity and foundation ditch of whole pre-formed members post inside.
As technique scheme preferably, the top of foundation ditch and bottom are provided with the stiffener net being made up of the reinforcing bar of horizontal and vertical both direction respectively.
As technique scheme preferably, between foundation ditch, cage of reinforcement and pre-formed members post, fill up and fix by grouting pug.
As technique scheme preferably, the bottom of foundation ditch is provided with concrete cushion.
A kind of pre-formed members post that the utility model embodiment provides and the syndeton of foundation ditch, compared with prior art, advantage of the present utility model is just: once the grouting material pouring into solidifies, will between pre-formed members post and foundation ditch, form a perfect homogeneous is connected, its duty is as same entirety, not yielding and avalanche.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the pre-formed members post of the utility model embodiment and the syndeton of foundation ditch.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the syndeton of a kind of pre-formed members post and foundation ditch, is made up of foundation ditch 1, cage of reinforcement and pre-formed members post 2, and cage of reinforcement is made up of the embedded ribs 31 vertically arranging, the ring-shaped stirrup 32 that laterally bundlees embedded ribs; Pre-formed members post 2 hollows and open top, and be positioned at foundation ditch 1 top, cage of reinforcement runs through between the cavity and foundation ditch 1 of whole pre-formed members post 2 inside, the top of foundation ditch 1 and bottom are provided with the stiffener net 4 being made up of the reinforcing bar of horizontal and vertical both direction respectively, between foundation ditch 1, cage of reinforcement and pre-formed members post 2, filled up and fixed by grouting pug, the bottom of foundation ditch is provided with concrete cushion 5.
Foundation ditch is a cube of solid, its top is the cage of reinforcement outside outstanding foundation ditch, to be connected with pre-formed members post, simultaneously with the buffering power that pillar was born, after once foundation ditch completes, pre-formed members post need be installed on foundation ditch, the cavity of pre-formed members post is inserted in the cage of reinforcement outside outstanding foundation ditch, next, use the flow grouting pug of shrinkage-void to pour into and fill up this post hole, this mud is a kind of high-intensity slurry, and intensity approximately can reach 60-70 MPas, specially for grouting or anchoring design.
Consequently, once the grouting material pouring into solidifies, will between pre-formed members post and foundation ditch, form a perfect homogeneous and be connected, its duty is as same entirety.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
