The construction of abnormity case beam, the general construction of combination set shaped steel formwork, the set shaped steel formwork good integrity of adopting, good looking appearance, impression quality is good, but the major defect that steel form exists is: (1) is for not reusing except that the engineering this engineering, serious waste of resources, the cost height; (2) hanging device that template is installed and dismounting need be large-scale; (3) the assembling and disassembling construction period is long; (4) potential safety hazard is big in the assembling and disassembling process.
The utility model content
The purpose of this utility model is that the waste that exists in the prior art is big, cost is high, assembling and disassembling is inconvenient, the problem of poor stability in order to solve, and then proposes a kind of combination steel carriage and special-shaped case joist steel wood gang form system thereof.
Content of the present utility model is: a kind of combination steel carriage, comprise two joints or the three knots joint that connect by securing member, described each son joint comprises that string beam, supporting steel pipe, bottom girder, described string beam are positioned at the top of this son joint, its shape and case beam surface configuration coupling; Described bottom girder is positioned at the bottom of this son joint, and described supporting steel pipe is connected between string beam and the bottom girder.
Described string beam is by wing web and strengthen steel plate and form, and described wing web is parallel to case beam surface, described reinforcement steel plate perpendicular to wing web, be welded on the middle part of wing web, the cross section of described string beam is "T"-shaped structure.
Described bottom girder is an i iron.
The vertical junction that described adjacent son saves is vertical connection steel plate, and is provided with securing member; The bottom girder of the junction that described adjacent son saves is provided with active plate.
Described supporting steel pipe perpendicular to the bottom girder setting, also is provided with oblique steel pipe between the described adjacent supporting steel pipe for vertically, makes each son joint form trussed construction.
A kind of special-shaped case joist steel wood gang form system comprises the rack platform of bottom, rack platform top be aforesaid combination steel carriage, the top of making up the steel carriage is provided with top wooden a tree, used in making timber for boats is installed, and on the top of wooden a tree, used in making timber for boats template is set.
Be provided with jacking between described rack platform and the combination steel carriage.
The beneficial effects of the utility model
This combination steel carriage and special-shaped case joist steel wood gang form system thereof are when can guaranteeing bridge appearance and modeling and quality, and its advance is mainly reflected in:
(1) the wooden a tree, used in making timber for boats in the template system, template can be had enough to meet the need use, save ample resources, and construction costs is low;
(2) template is installed and removed does not need large-scale hanging device;
(3) the assembling and disassembling construction is succinct convenient, and the construction period is short;
(4) owing to component quality in the assembling and disassembling process reduces, unit type is little, and potential safety hazard has reduced much relatively.
