Abstract

The utility model relates to the technical field of building pouring, and particularly discloses a raft foundation steel bar binding supporting structure. The raft foundation steel bar binding supporting structure comprises a plurality of longitudinal steel pipes arranged inside a raft, wherein one end of each longitudinal steel pipe makes contact with the bottom surface of the raft, the other end of each longitudinal steel pipe extends outside the raft to form an extending portion, and the longitudinal steel pipes are provided with a plurality of horizontal steel pipes and provided with a plurality of steel bar meshes in a welded mode. The raft foundation steel bar binding supporting structure has the advantages that the longitudinal steel pipes are adopted to replace split heads in the prior art to support upper mesh steel bars. As the longitudinal steel pipes are hollow, heat in concrete can be exhausted through the longitudinal steel pipes staying in the concrete, internal temperature of the concrete is reduced, and the cooling effect is achieved.

Description

Raft foundation reinforcing bar binding braced structures
Technical field
The utility model relates to building pouring technique field, refers to especially a kind of raft foundation reinforcing bar binding braced structures.
Background technology
Along with the continuous increase of highrise building, super highrise building is also in continuous increase, and Raft Foundation Design is also in continuous variation, plank thickness is increasing, the continuous overstriking of bar gauge, and reinforcing bar designs also from originally only having bottom and top layer to become multilayer, bring very large difficulty to the support of reinforcing bar
At present, made supporting steel bar for the reinforcing bar that raft foundation is identical, weld horizontal reinforcing bar on supporting steel bar, relies on the fixing supporting steel bar of horizontal reinforcement, supports upper wire sheet reinforcing bar, then colligation upper wire sheet reinforcing bar on horizontal reinforcement by supporting steel bar.Raft foundation reinforcing bar binding supports and adopts reinforcing bar Site Welding to make split heads, but the support of super raft foundation reinforcing bar, due to reinforcing bar poor stability, it is stable that very difficult guarantee is made, and can not meet the stability of super raft foundation reinforced bar support.
Utility model content
The purpose of this utility model is to provide a kind of raft foundation reinforcing bar binding braced structures, adopts longitudinal steel pipe to replace supporting steel bar of the prior art to support upper wire sheet reinforcing bar, and longitudinally steel duct is hollow, and its thermal conductivity is good, and construction quality is high.
To achieve these goals, the utility model has adopted following technical scheme: a kind of raft foundation reinforcing bar binding braced structures, comprise the multiple longitudinal steel pipe being placed in raft plate, this Yu Faban bottom surface, longitudinal steel pipe one end contact, the other end extends to the outer extension that forms of raft plate, described longitudinal steel pipe is provided with multiple horizontal steel tubes, on described longitudinal steel pipe, is also welded with multiple reinforced mesh.
Further, be welded with the reinforcing bar pawl corresponding with reinforced mesh quantity on described longitudinal steel pipe, described reinforced mesh is fixed on longitudinal steel pipe by this reinforcing bar pawl.
Further, described longitudinal steel pipe is connected by buckle with horizontal steel tube.
Further, described longitudinal steel pipe bottom welding has a supporting steel plate, and this supporting steel plate is placed in raft plate bottom surface.
Further, described longitudinal steel pipe is provided with seal ring.
Further, described extension length is 20mm.
Further, described seal ring is fixed on longitudinal steel pipe by full weld mode.
The beneficial effects of the utility model are: adopt after said structure, adopt longitudinal steel pipe to replace supporting steel bar of the prior art to support upper wire sheet reinforcing bar.Because longitudinally steel duct is hollow, longitudinal steel pipe of staying in concrete can be discharged the heat in concrete, reduces internal temperature in concrete, plays thermolysis.
This braced structures forms a stable entirety with reinforcing bar in raft plated construction, provides a stable operating platform in structure construction simultaneously, has reduced construction cost, saves the duration of on-the-spot interim processing split heads, improves construction quality.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that this practicality is 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, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of raft foundation reinforcing bar binding braced structures as shown in Figure 1, comprises the multiple longitudinal steel pipe being placed in raft plate, and this longitudinal steel pipe (1) external diameter is 48mm, and wall thickness is 2mm; Adopt longitudinal steel pipe (1) to replace supporting steel bar of the prior art to support upper wire sheet reinforcing bar.Due to longitudinal steel pipe (1) boring, longitudinal steel pipe (1) of staying in concrete can be discharged the heat in concrete, reduces internal temperature in concrete, plays thermolysis.
This Yu Faban bottom surface, longitudinal steel pipe (1) one end contact, the other end extends to the outer extension that forms of raft plate.Concrete, described longitudinal steel pipe (1) bottom welding has a supporting steel plate (5), and this supporting steel plate (5) is placed in raft plate bottom surface, and described extension length is 20mm.Supporting steel pipe prevents that concrete from entering the problem that longitudinal steel pipe (1) causes its congestion affects heat radiation.
Described longitudinal steel pipe (1) is provided with multiple horizontal steel tubes (2), and described longitudinal steel pipe (1) is connected by buckle with horizontal steel tube (2), facilitates the installation and removal of horizontal steel tube (2).
On described longitudinal steel pipe (1), be welded with the reinforcing bar pawl (3) corresponding with reinforced mesh quantity, it is upper that described reinforced mesh is fixed on longitudinal steel pipe (1) by this reinforcing bar pawl (3), and reinforced mesh is welded on longitudinal steel pipe (1) equally.
Described longitudinal steel pipe (1) is provided with seal ring (4), and is fixed on longitudinal steel pipe (1) by full weld mode.It has prevented the generation of infiltration situation.
This braced structures forms a stable entirety with reinforcing bar in raft plated construction, provides a stable operating platform in structure construction simultaneously, has reduced construction cost, saves the duration of on-the-spot interim processing split heads, improves construction quality.
In when construction, with adhesive tape by longitudinal steel pipe (1) upper end shutoff, to prevent that concrete from entering longitudinal steel pipe (1); After having constructed, remove adhesive tape, so that its heat radiation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
