Abstract
The utility model discloses a horizontal embedding support structure for a post-pouring belt of top-down construction, which comprises beam plates arranged on two sides of a post-pouring belt. The structure is characterized by further comprising an embedded profile steel horizontally disposed, and two ends of the embedded profile steel are respectively embedded into the beam plates on two sides. The structure changes a vertical support manner of the pose-pouring belt in top-down phase, uses the beam plates on two sides of the post-pouring belt for the horizontal embedded profile steel to be embedded into, accordingly alters vertical support into horizontal embedding support and eliminates lattice upright columns on two sides of the post-pouring belt. The horizontal embedding support of the structure is capable of guaranteeing transfer continuity of horizontal load, resolving the problem of difficult support replacement of the post-pouring belt in top-down construction, simplifying support replacement construction technique, and lowering construction cost.
Description
Technical field
The utility model belongs to building underground construction technical field, relates to a kind of reverse construction horizontal support structure, the horizontal build-in braced structures in specifically a kind of adverse construction method ater-casting.
Background technology
Reverse construction is owing to cut the earth and the flow process of structure construction limits, in case descend one deck shoveling framed bent just to need dismounting, so the framed bent support replacement can not be adopted in the shoveling stage in the position, ater-casting.Standard practice is to set the lattice column in advance in the both sides, ater-casting, supports the vertical load of both sides, ater-casting with the lattice column.In addition, the continuity that be to keep horizontal loading to transmit, after water the position and also need horizontal support replacement.This construction technology complexity, the construction cost height.
Summary of the invention
Technical problem to be solved in the utility model provides the horizontal build-in braced structures in adverse construction method ater-casting that a kind of construction technology is simple, construction cost is low, to overcome the high defective of construction technology complexity, construction cost that prior art exists.
The horizontal build-in braced structures in a kind of adverse construction method ater-casting comprises the beam slab that is arranged on the both sides, ater-casting, it is characterized in that, also comprises horizontally disposed pre-buried shaped steel, and described pre-buried shaped steel two ends are embedded into respectively in the beam slab of both sides.
Further, to embed the distance of beam and slab structure inside, both sides respectively be 80cm～120cm at described pre-buried shaped steel two ends.
Pre-buried shaped steel in the beam slab of both sides, ater-casting, the inner 1m of shaped steel embedded structure, with its vertical support as the ater-casting structure on two sides, this support simultaneously can guarantee the continuity that horizontal loading transmits.
By above disclosed technical scheme as can be known, the utility model is by changing the ater-casting at the contrary vertical supporting form of doing the stage, utilize the beam slab of both sides, ater-casting, be embedded in the pre-buried shaped steel of level at beam slab, change horizontal build-in support, the lattice column of cancellation both sides, ater-casting into thereby will vertically support, the horizontal build-in of the utility model supports the continuity that can guarantee that horizontal loading transmits, solved the problem of ater-casting support replacement difficulty in the adverse construction method, the support replacement construction technology is simplified, construction cost reduces.
Description of drawings
Fig. 1 is the utility model structural representation.
Reference numeral is as follows:
1, beam slab 2, pre-buried shaped steel
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As described in Figure 1, the horizontal build-in braced structures in the utility model adverse construction method ater-casting comprises the beam slab 1 that is arranged on the both sides, ater-casting, also comprises horizontally disposed pre-buried shaped steel 2, and described pre-buried shaped steel 2 two ends are embedded into respectively in the both sides beam slab 1.
The distance L that described pre-buried shaped steel 2 two ends embed both sides beam slab 1 inside configuration respectively is 100cm.
The utility model job practices:
1, as shown in Figure 1, the ater-casting structure on two sides waters smashes bed course, sets up the framed bent template.
2, colligation primary and secondary beam main tendon, the pre-buried shaped steel 2 of horizontal build-in is put into before the stirrup colligation is intact.
3, treat ater-casting structure on two sides concrete design strength 80% stripping and bottom framed bent, following one deck structure is contrary to be done.
The above is a better embodiment of the present utility model only, is not to be used for limiting protection domain of the present utility model, and every equal conversion of being done according to the utility model claim is all within protection domain of the present utility model.
Claims (2)
1. the horizontal build-in braced structures in adverse construction method ater-casting comprises the beam slab (1) that is arranged on the both sides, ater-casting, it is characterized in that, also comprises horizontally disposed pre-buried shaped steel (2), and described pre-buried shaped steel (2) two ends are embedded into respectively in the both sides beam slab (1).
2. the horizontal build-in braced structures in adverse construction method according to claim 1 ater-casting is characterized in that, the distance that described pre-buried shaped steel (2) two ends embed both sides beam slab (1) inside configuration respectively is 80cm～120cm.
