Abstract
The utility model discloses a novel joint construction of prefabricated staircase and stair railing pole setting, include steel pipe, iron sheet, bolt, nut, the steel pipe is cylindrical cavity, forms the tubbiness cylinder with steel pipe bottom and the welding of circular iron sheet, the round hole that supplies the bolt to run through is seted up at the iron sheet middle part, the head of bolt and the pre -buried one -tenth of prefabricated staircase are integrative, and this bolt afterbody runs through the iron sheet and closes with the nut spiral shell and be connected, make steel pipe and prefabricated staircase fastening connection. 1. Connecting piece processing is simple, assembles easily. 2. Solved and to have beaten complicated processes such as expansion bolts and electric welding when prefabricated staircase surface, installation can be destroyed to current connected mode. 3. Stair railing can take one's place together with stair, avoid secondary transportation and installation. 4. Save installation of interim handrail and freight, reduced stair railing installation time and labour cost.
Description
Technical field
This utility model relates to the connecting structure of prefabricated concrete structure, metal structure field, the most more convenient precast stair and balustrade vertical rod.
Background technology
Architectural industrialization is the inexorable trend of construction industry development, and mechanization production and the standardization of building supporting structure are installed and efficiency of construction can be greatly improved, and save construction cost.
Precast stair is a kind of version of assembled architecture.It produces simple, and easy for installation, beautiful appearance, is therefore expanded as the version of assembled architecture at first.Existing precast stair is to need to beat expansion bolt on surface after stair are installed with the connected mode of balustrade vertical rod, then balustrade vertical rod is attached with precast stair by welding.The method existence needs problems such as should not changing when playing the complicated procedures of forming such as expansion bolt and electric welding, stair damage when can destroy precast stair surface, installation.It would therefore be desirable to have a kind of novel precast stair and the connecting structure of balustrade vertical rod.
Summary of the invention
It is an object of the invention to provide the connecting structure of a kind of novel precast stair and balustrade vertical rod, need to beat expansion bolt on surface during for solving balustrade installation in building construction process, then problem balustrade vertical rod and precast stair being attached by welding, makes construction simplerization, economization, high efficiency.Meanwhile, balustrade maintenance change time simpler fast.
The technical solution of the utility model:
A kind of novel precast stair and the connecting structure of balustrade vertical rod, including, steel pipe, iron plate, bolt, nut；Described steel pipe is circular cylindrical cavity, will weld formation tubbiness cylinder with round iron plate bottom steel pipe；The circular hole for bolt-through is offered in the middle part of described iron plate；The head of described bolt is pre-buried with precast stair integral, and this bolt tail runs through iron plate and is screwed together with nut；Steel pipe is made to be fastenedly connected with precast stair.
Effect of the present utility model:
1. connector processing is simple, easily assembled.
2. solve when existing connected mode can destroy precast stair surface, installation and need to beat the complicated procedures of forming such as expansion bolt and electric welding.
3. balustrade can be in place together with stair, it is to avoid secondary conveying and installation.
4. save temporary armrest to install and freight, reduce balustrade set-up time and labour cost.

Detailed description of the invention
Below in conjunction with Figure of description and reference, this utility model is further described.
As Figure 1-5, a kind of novel precast stair and the connecting structure of balustrade vertical rod, including, steel pipe 1, iron plate 2, bolt 3, nut 4；Described steel pipe 1 is circular cylindrical cavity, will weld formation tubbiness cylinder 5 with round iron plate 2 bottom steel pipe 1；The circular hole run through for bolt 3 is offered in the middle part of described iron plate 2；The head of described bolt 3 is pre-buried with precast stair integral, and this bolt 3 afterbody runs through iron plate 2 and is screwed together with nut 4；Steel pipe 1 is made to be fastenedly connected with precast stair.
Described steel pipe 1 top is provided with the chamfering facilitating balustrade to insert.Described steel pipe 1 exterior side wall is provided with convex-concave drag ring.Steel pipe 1 diameter is 40mm.The thick 2mm of iron plate 2.Bolt 3 uses M16 screw, nut 4 to use M16 nut.
Embodiment
After precast stair is transported to job site, circular to diameter 40mm steel pipe 1 and 2mm thickness iron plate 2 with holes is welded together to form barreled cylinder 5.It is fixed as balustrade connector with M16 nut 4 after being connected by pre-buried to cylinder 5 and precast stair M16 screw and completes connector combination.
Before precast stair lifting, on ground, balustrade being inserted connector, then precast stair is installed in lifting.Complete also to complete while stair are installed the installation of balustrade.
