Abstract
The utility model discloses an angle sign indicating number connection mode PC stair, PC stair including tip reservation joint bar hole, with the PC stair are connected is used for supporting the bracket support of PC stair, wherein the PC stair are fixed on the bracket support through reserving the joint bar, the fixed setting of bracket support is structural at building subject. Adopt the utility model discloses having cancelled the building process of reserving joint bar etc. On apron piece and the cushion cap, having practiced thrift construction material simultaneously, the installation location is accurate, makes the construction more convenient, and stair can come into operation rapidly.
Description
Technical field
The utility model relates to PC stair field for building, in particular a kind of corner brace interconnection system PC stair.
Background technology
Traditional PC stair are often supported on the Cast-in-place concrete component of agent structure, and the connected node construction at stair bearing place is often comparatively complicated, when not yet maintenance is shaping for bearing Cast-in-place concrete, the stair caused as important vertical passageway cannot be installed and used, greatly reduce efficiency of construction.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of corner brace interconnection system PC stair, can save construction material, convenient construction.
The technical solution of the utility model is as follows:
A kind of corner brace interconnection system PC stair, comprise the PC stair that connecting end portion is provided with reserved joint bar hole, the bracket bearing for supporting described PC stair be connected with described PC stair;
The connecting end portion of wherein said PC stair is supported on bracket bearing, and rear pouring concrete tamps hole and fixes described PC stair after inserting PC gangboard reserved opening by joint bar that bracket bearing is arranged, described bracket bearing is fixedly installed on described major structure of construction by branch sleeve again.
Further, described corner brace interconnection system PC stair, wherein, described bracket bearing are welded with stiffening rib.
Further, described corner brace interconnection system PC stair, wherein, described bracket bearing is connected by reserved joint bar with described PC stair.
Further, described corner brace interconnection system PC stair, wherein, are embedded with the bolt sleeve for being connected and fixed described bracket bearing in described major structure of construction.
Further, described corner brace interconnection system PC stair, wherein, described bracket seat structure is connected with described bolt sleeve by connecting bolt.
Corner brace interconnection system PC stair provided by the utility model, owing to have employed bracket seat supports PC stair, eliminate the building operation of apron piece, thus can reduce diagonal brace effect, saved construction material simultaneously, reduce construction error, make construction convenient.

Detailed description of the invention
The utility model provides a kind of corner brace interconnection system PC stair, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes the utility model referring to accompanying drawing examples.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 to Fig. 4, the utility model provides a kind of corner brace interconnection system PC stair, comprises PC stair 1, bracket bearing 5 and bolt sleeve 4.Wherein PC stair 1 connect end and are provided with reserved joint bar hole 7, and the bracket bearing 5 be connected with described PC stair 1 is fixed on bracket bearing 5 by reserved joint bar 2 for supporting described PC stair 1, PC stair 1.The bolt sleeve 4 for being connected and fixed described bracket bearing 5 is embedded with in described major structure of construction 3.During concrete enforcement, bracket bearing 5 is fixed on major structure of construction 3 place by bolt sleeve 4.PC stair 1 connecting end portion is provided with two reserved joint bar holes 7, bracket bearing 5 carries the joint bar hole 7 of the corresponding described PC stair 1 of reserved joint bar 2, during lifting, the reserved joint bar 2 of bracket bearing 5 is put into the joint bar hole 7 of PC stair 1, then with water concrete and tamp joint bar hole 7.Because conventional P C stair 1 are supported on the Cast-in-place concrete component of major structure of construction 3, not only construction sequence is complicated, efficiency of construction is also lower, so the utility model adopts the PC stair 1 of corner brace interconnection system to be directly supported on bracket bearing 5, and is connected with PC stair 1 by joint bar 2 reserved on bracket.
As shown in Fig. 2 Fig. 3 and Fig. 4, during fixing bracket bearing 5, specifically can on described major structure of construction 3 pre-buried two for being connected and fixed the bolt sleeve 4 of described bracket bearing 5, then bracket bearing 5 and described major structure of construction 3 connecting bolt 8 are fixed, connecting bolt 8 is threaded with described bolt sleeve 4.Connecting bolt 8 can put into the pre-buried screw shell of major structure of construction 3 through the bolt hole on bracket bearing 5, then add bolt backing plate 9 and fix bracket bearing 5, and certain bolt backing plate 9 adopts nut to be pressed on connecting bolt 8.
Due to the pre-buried bolt sleeve 4 of major structure of construction 3, bracket bearing 4 is fixedly connected with bolt with by sleeve 4 with agent structure 3, during lifting PC stair 1, first PC stair 1 are positioned, by the prefabricated gangboard of PC stair 1() be supported on bracket bearing 5, then described bracket bearing 5 is connected and fixed by reserved joint bar 2 with described PC stair 1.PC stair 1 installation can be come into operation later, becomes the important channel that major structure of construction 3 is constructed, transported, and the technical scheme of utility model is simple, use, is convenient to promote.
Further, in described corner brace interconnection system PC stair, described bracket bearing 4 is also welded with stiffening rib 6, to increase the supportive of bracket bearing 4.
In sum, corner brace interconnection system PC stair provided by the utility model, support PC stair 1 owing to have employed bracket bearing 5, eliminate the building operation of apron piece, thus can reduce diagonal brace effect, saved construction material simultaneously, make construction convenient.
Should be understood that; application of the present utility model is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert; such as, all these improve and convert the protection domain that all should belong to the utility model claims.
