Description

A kind of falsework for the construction of outer-enwraped type Guard fence base

Technical field

The utility model relates to Collison fence for bridge technical field of construction, and in particular to one kind is used for bridge outer-enwraped type guardrail The detachable falsework of basement construction.

Background technique

Traditional highway bridge guardrail form is mostly brace type, i.e. Guard fence base is completely supported on bridge flange plate, shield When column pedestal pouring construction, the medial and lateral template of Guard fence base can be all supported directly on bridge flange plate, between inside and outside template By being fixed to pull rod.Because there are construction joints between the anticollision barrier base bottom and bridge flange plate of this form, influence whole External to see, then outer-enwraped type Guard fence base comes into being.As shown in Figure 1, outer-enwraped type guardrail 1 is located at bridge flange plate 2 below Bottom, from the appearance outer-enwraped type guardrail and bridge are one complete whole therefore more beautiful.But outer-enwraped type Guard fence base exists Outboard template can not be supported directly on the bridge edge of a wing when construction, but be suspended on the outside of flange plate, if medial and lateral template is still logical It crosses and pull rod is connected, because the ability of pull rod resist torque is lower, outboard template downwarp certainly will be will lead to, increase difficulty of construction, Also the construction quality of anticollision barrier pedestal is influenced.

Summary of the invention

The purpose of this utility model is that providing one kind aiming at the problem that outer-enwraped type Guard fence base outboard template is not fixed easily For the falsework of outer-enwraped type Guard fence base construction, exterior sheathing is suspended in midair by bracket and exterior sheathing is fixed.

The technical solution of the utility model is as follows:

A kind of falsework for the construction of outer-enwraped type Guard fence base, it is characterised in that: including a vertically arranged support Frame, support frame as described above lower end are equipped with the pedestal being supported on bridge flange plate, and a horizontally disposed spandrel girder is set up in upper end, described Spandrel girder is spliced side by side using two panels truss, and reinforcement welding is used between two panels truss；The rear end of spandrel girder connects two The upper end of vertically arranged anchor rod, the lower end of two anchor rods are connected on the inside of bridge on Guard fence base；Before the spandrel girder One vertically arranged template sunpender of end connection, the template sunpender are fixedly connected with Guard fence base exterior sheathing.

The main spandrel girder of the utility model uses truss form, and rigidity is larger, and bracket is directly fixed with outboard template, from knot Solves the problems, such as template downwarp in structure stress, concreting effect is preferable.Bracket is made of each section of different function, respectively Part quick-detach can assemble fastly, improve construction efficiency.

Specific embodiment

As shown in Fig. 2, the utility model includes a vertically arranged support frame 3,3 lower end of support frame as described above is equipped with and is supported on A horizontally disposed spandrel girder 5 is set up in pedestal 4 on bridge flange plate 2, upper end, and the spandrel girder 5 is arranged side by side using two panels truss It is spliced, reinforcement welding is used between two panels truss；The rear end of spandrel girder 5 connects the upper of two vertically arranged anchor rods 6 End, the lower end of two anchor rods 6 are connected on the inside of bridge on Guard fence base 7；The front end connection one of the spandrel girder 5 is vertically arranged Template sunpender 8, the template sunpender 8 are fixedly connected with Guard fence base exterior sheathing 9.

As shown in figure 3, support frame as described above 3 includes two vertical bars 31, the spacing of two vertical bars 31 is greater than or equal to the load-bearing The width of beam, the lower end of two vertical bars 31 are welded with the pedestal 4 respectively, are connected by place near to the upper end by a cross bar 32 between two vertical bars It connects, the spandrel girder 5 is supported on the cross bar 32 between two vertical bars.

As shown in figure 4, the anchor rod 6 includes a U-shaped muscle 61, under the both ends of the U-shaped muscle 61 and a screw-thread steel 62 End welding, gap of the upper end of the screw-thread steel 62 across two truss of spandrel girder, and purlin is fixed on backing plate and nut 10 The top boom top surface of frame；Intert a positioning bar 11, two anchor rods 6 on the inside of the bridge in the transverse drain duct of Guard fence base 7 U-shaped muscle 61 be hung in the both ends of the positioning bar 11.

As shown in figure 5, the template sunpender 8 is L-type；Gap of 8 upper end of template sunpender across two truss of spandrel girder, And the top boom top surface of truss is fixed on backing plate and nut；The lower end of template sunpender 8 sets an elbow 81, and 8 support of elbow is in guardrail 9 bottom of pedestal exterior sheathing；Template sunpender is equipped at least two connecting rods 82, the connecting rod 82 and Guard fence base exterior sheathing 9 Back cord be bolted, or be welded to connect.

The utility model is detachable structure, when for constructing, by each component on-site assembly.First on bridge flange plate 2 Support frame 3 is erect and fixed, spandrel girder 5 is lifted by crane and ridden upon on the cross bar of support frame with loop wheel machine, the side rail in bridge Intert positioning bar 11 in the transverse drain duct of pedestal 7, the both ends of positioning bar protrude from the two sides of Guard fence base on the inside of bridge, The U-shaped muscle of two anchor rods 6 is respectively fitted over to the both ends of positioning bar 11；Two anchor rod upper ends are across two truss pieces of spandrel girder Gap, install and tighten nut in anchor rod upper end, make two anchor rods U-shaped muscle tense positioning bar 11.Again by template sunpender 8 It is fixed with Guard fence base outboard template 9, sunpender and outboard template are lifted by crane by crane, by sunpender be placed in two truss piece of spandrel girder it Between gap, adjust sunpender and outboard template to appropriate height, tighten nut in sunpender upper end.Entire falsework installs At then according still further to routine operation installation Guard fence base inner side template 12, progress concrete pouring construction.
