Abstract
The invention discloses a telescopic formwork support beam. The telescopic formwork support beam comprises a sub beam, a main beam, ribs, pin bolts and pin holes, wherein the main beam is a ladder-shaped strip truss, upper and lower edges of the main beam are steel pipes, and the two steel pipes are fixedly connected by the ribs, and the tilting angles of the ribs on the two ends are equal; 6-10 axial equally-spaced pin holes are respectively arranged on the two ends of the upper and lower edges of the main beam, the sub beam is an open shaped frame, the upper and lower edges of the sub beam are steel pipes, and the outer end of the sub beam is fixedly connected by two tilting ribs along the same direction; the tilting angles of the ribs connected with the sub beam are equal to that of the ribs connected with two ends of the main beam; and the upper and lower edges of the open end of the sub beam are respectively axially inserted into pipes on the two ends of the main beam to form a nesting structure, and the sub beam is positioned relatively to the axial mounting position of the main beam by making the pin bolt traverse the pin hole. The telescopic formwork support beam is in a truss structure, the length of the beam is adjustable, and the structure strength is good; and during the mounting process, the mated vertical top brace is less, thus the auxiliary materials are saved, and the traffic space of the construction site is improved; and more importantly, the telescopic formwork support beam can be repeatedly used and the use cost can be saved.
Description
Technical field
The present invention relates to a kind of building operations and use mould bases, specifically, the present invention relates to the template brace summer that a kind of building operations is used.
Background technology
Cast in situs is one of main construction task in the Contemporary Architecture engineering.The model of building for member to be built must have firm support, and brace summer except that considering rigidity and requirement of strength, also will be considered convenient construction installation and application cost problem as the basic member of load-bearing during making.Generally use steel pipe to set up framed bent in the current engineering, on framed bent, make the brace summer of template again with flitch or steel pipe, the brace summer size that this kind amount body is made surely accurately, be in place, support reliable, can satisfy the requirement of cast in situs construction quality.But, in the engineering brace summer of field fabrication exist materials many, from great, make man-hour long, length is unadjustable, and will make shortcoming such as destructive dismountings after using, these problems also increase construction cost except that having restricted construction speed.
Summary of the invention
The present invention is primarily aimed at the deficiency of the technology of field fabrication in the engineering, proposes a kind of simple in structure, making is easy, easy for installation, versatility is good telescoping formwork brace summer.This beam is made length adjustment within the specific limits, and is flexible for installation, helps on-the-spot the installation.
The present invention realizes technical goal through following technical proposals.
The telescoping formwork brace summer, it comprises auxiliary girder, girder, rib, pin and pin-and-hole.Said girder front shape is the up big and down small rectangular truss of isosceles trapezoid; The bottom of going up that is parallel to each other is steel pipe; Be fixedly connected by the rib that is wavy arrangement between two pipes, ends of tubes is provided with 6～10 pin-and-holes of axially equidistantly arranging, and the oblique angle at girder two ends equates.Said auxiliary girder is an opening shape frame, and the bottom of attending that is parallel to each other also is a steel pipe, and two pipe outer ends are fixedly connected by two tilting in the same way ribs, and rib is identical with girder with the oblique angle α of following pipe, the following pin-and-hole that matches with the girder two ends that is provided with on the auxiliary girder opening.Its improvements are: said auxiliary girder forms shrink-fit structure with following axially the insertion in the pipe of girder two ends respectively on the openend, and the pin-and-hole location is laterally run through by pin in the axial installation site of the relative girder of auxiliary girder.
In the said structure, the bottom of attending of auxiliary girder and girder is square hollow steel pipe, also can use the circular hollow steel pipe manufacturing.The oblique angle α at girder two ends is 50 °～60 °.
Field fabrication compared with techniques in the present invention and the engineering has the following advantages:
1, the beam of trussed construction, materials are economized, are made easily;
2, axial stretching structure satisfies on-the-spot span difference, highly versatile in the certain size scope;
3, the beam stress of trussed construction is reasonable, and intensity is high, the rigidity foot, supports steady quality;
4, metal fabrication can use repeatedly, and average use cost is low;
5, the bottom need not to set up supporting row frame, and is convenient current, saves a large amount of backing materials.
Description of drawings
Fig. 1 is that structure master of the present invention looks sketch map.
Fig. 2 is Figure 1A-A section enlarged diagram.
The specific embodiment
According to accompanying drawing and structure embodiment, the present invention is described further below.
Telescoping formwork brace summer embodiment shown in Figure 1, it comprises auxiliary girder 1, girder 2, rib 3, pin 4 and pin-and-hole 5.Said girder 2 front shape are the up big and down small rectangular truss of isosceles trapezoid; The oblique angle at girder 2 two ends is 60 °; The bottom of going up that is parallel to each other is rectangular steel tube, is fixedly connected by the rib that is wavy arrangement 3 between two pipes, and ends of tubes is provided with the pin-and-hole 5 that 8 axially equidistant 50mm arrange.Said auxiliary girder 1 is an opening shape frame; The bottom of attending that is parallel to each other also is a rectangular steel tube; Two pipe outer ends are fixedly connected by two tilting in the same way ribs 3, and rib 3 is identical with girder with the oblique angle α of following pipe, and bottom is provided with 8 pin-and-holes 5 that match with girder 2 two ends on auxiliary girder 1 openend.Auxiliary girder 1 forms shrink-fit structure with following axially the insertion in the pipe of girder 2 two ends respectively on the openend, and pin-and-hole 5 location are laterally run through by pin 4 in the axial installation site of auxiliary girder 1 relative girder 2.
During practical application of the present invention, be contracted in support shutterings in the girder 2 with auxiliary girder 1 earlier, the auxiliary girder 1 of pulling out one or both ends according to the job site size is then regulated span, accomplishes completely to stride support.Because length can be stretched when the present invention installed, help on-the-spot the installation.Trussed construction intensity is good, and two ends directly cover hang on the beam side that is fixed well, and need not perpendicular shoring, and helps saving auxiliary material, improves the job site passage space.Integral body is taken off during dismounting, in contract auxiliary girder 1 reduce length dimension, be convenient to collection and transportation, the most important thing is and can use repeatedly, reduce use cost greatly.
During practical application of the present invention, girder 2 and auxiliary girder 1 go up the following circular steel pipe that changes, it should have effect similar with rectangular steel tube.
