Abstract
The utility model discloses a retractable template supporting beam. The retractable template supporting beam comprises an auxiliary beam, a main beam, rib strips, pins and pin holes, wherein a trapezoidal long-strip truss is used as the main beam, and the upper and lower sides of the main beam are steel tubes; the two steel tubes are fixedly connected by the rib strips; and oblique angles of the ribs strips at the two ends are equivalent. 6-10 pin holes which are axially arranged at equal intervals are respectively arranged in the two ends of upper and lower sides of the main beam; an opening-shaped frame is used as the auxiliary beam, and the upper and lower sides of the auxiliary beam are steel tubes; and the outer end of the auxiliary beam is fixedly connected by two rib strips which are inclined in the same direction. The oblique angles of the rib strips connected with the auxiliary beam are equal to those of the rib strips connected with the two ends of the main beam. The auxiliary beam is axially inserted to the tubes at the two ends of the main beam through upper and lower sides of the opening end to form a sleeve structure, respectively; and the auxiliary beam is positioned relative to the axial installation position of the main beam in a mode that the pins transversely get through the pin holes. The retractable template supporting beam is in a truss structure, has adjustable length, good structural strength and a few supporting top back shores when installed, so that not only auxiliary material is saved, but also travel space of a construction site is improved; and more importantly, the retractable template supporting beam can be used repeatedly, so that using cost is saved.
Description
Technical field
The utility model relates to a kind of building operations mould bases, and specifically, the utility model relates to the pattern plate strutting beam 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 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 again the brace summer of template 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 that man-hour is long, length is unadjustable, and to make the shortcoming such as destructive dismountings after using, these problems are removed and have been restricted construction speed and also increase construction cost.
The utility model content
The utility model is mainly for the deficiency of field fabrication technology 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, is conducive to on-the-spot the installation.
The utility model is achieved through the following technical solutions technical goal.
The telescoping formwork brace summer, it comprises auxiliary girder, girder, rib, pin and pin-and-hole.Described girder front shape is the up big and down small rectangular truss of isosceles trapezoid, the upper bottom that is parallel to each other is steel pipe, be fixedly connected with 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.Described auxiliary girder is opening shape frame, and the upper bottom that is parallel to each other also is steel pipe, and two pipe outer ends are fixedly connected with 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: described 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 upper bottom 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 °.Spacing 50mm～100mm between the pin-and-hole of auxiliary girder and girder.
The utility model is compared with field fabrication technology in 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, adequate rigidity, supports steady quality;
4, metal fabrication, but Reusability, 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 the utility model structure master looks schematic diagram.
Fig. 2 is Figure 1A-A section enlarged diagram.
The specific embodiment
The below with reference to the accompanying drawings and structure embodiment, the utility model is described in further detail.
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.Described 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 upper bottom that is parallel to each other is rectangular steel tube, is fixedly connected with by the rib 3 that is wavy arrangement between two pipes, and ends of tubes is provided with the pin-and-hole 5 that 8 axially equidistant 50mm arrange.Described auxiliary girder 1 is opening shape frame, the upper bottom that is parallel to each other also is rectangular steel tube, two pipe outer ends are fixedly connected with 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 the utility model practical application, be contracted in girder 2 inner support templates with auxiliary girder 1 first, then pull out the auxiliary girder 1 adjusting span of one or both ends according to the job site size, accomplish completely to stride support.Because length can be stretched when the utility model was installed, be conducive to 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 is conducive to save auxiliary material, improves the job site passage space.Integral body is taken off during dismounting, inside contracts auxiliary girder 1 and reduces length dimension, is convenient to collection and transportation, and the most important thing is can Reusability, greatly reduces use cost.
During the utility model practical application, the circular steel pipe of upper following change of girder 2 and auxiliary girder 1, it should have effect similar with rectangular steel tube.
