Description

A kind of open trench tunnel square-section self-propelled mobile falsework chassis
Technical field
The present invention relates to a kind of constructing tunnel chassis, specifically a kind of open trench tunnel square-section self-propelled mobile template Support vehicles.
Background technology
In bored tunnel, two lining structures typically use the chassis system in arch cross section as falsework, but this body System takes full advantage of the pressure uniformly bearing concreting of domes, square-section vertical load comparatively speaking and side Area load, all much larger than arch cross section, therefore typically uses full framing system in the open trench tunnel of square-section.
But full framing system has the disadvantage that: (1) full framing is installed and the dismounting substantial amounts of material of needs is with artificial, Activity duration is longer, is unfavorable for the cost-effective and duration;(2) full framing system stress point is numerous, manually sets up, during thin Joint sets difficult quality control, and safe mass hidden danger is bigger;(3) template of full framing system is interim assembled, formwork edge joint Easily spillage, faulting of slab ends, after concrete formation, quality is the best;(4) side wall typically uses Screw arbor with nut at both-ends, easily at tunnel structure sidewall Form penetrating passage, for the most unfavorable from the point of view of the tunnel that waterproof requirement is high.
Summary of the invention
It is an object of the invention to provide a kind of cost-effective, open trench tunnel square-section self-propelled mobile that degree of accuracy is high Falsework chassis, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of open trench tunnel square-section self-propelled mobile falsework chassis, including door frame assembly, horizontal device, backform Support body crossbeam, top template and side form, door frame assembly includes door frame crossbeam, door frame grade beam, door frame column and longeron, door frame crossbeam It is vertically fixed on the top of door frame column by the big triangle of door frame, between two longitudinal door frame columns, uses diagonal brace to fix, horizontal To two door frame columns use that door frame grade beams are fixing to be connected, top, door frame crossbeam two ends is all installed with cross cylinder, water Leveling device two ends use jointed shaft to be connected with cross cylinder, cross cylinder is provided with hoist cylinder, hoist cylinder is provided with Longeron, backform support body crossbeam is arranged on door frame crossbeam by jack, and installs on the backform support body crossbeam above jack The longeron the most corresponding with jack, top template is fixed on backform support body crossbeam by backform support body longeron, longitudinal two Being connected by connecting plate bolt between the template of individual top, horizontal two top templates use and connect the connection of box bolt, top template It is connected by jointed shaft with side form, with bolts between horizontal side form, longitudinal side form is welded with many logical beams, logical Beam is provided with on hinge ear, door frame column and backform support body crossbeam and is all provided with hinged ear, with the hinge ear one_to_one corresponding on logical beam passing through Screw mandrel connects, and door frame crossbeam is respectively arranged at the two ends with two hinge ears, respectively by side form oil cylinder and screw mandrel and the hinge on corresponding logical beam Ear connects.
As the further scheme of the present invention: the logical beam on longitudinal side form is welded with five.
Compared with prior art, the invention has the beneficial effects as follows: need not substantial amounts of material and artificial, eliminate support and take And if the plenty of time removed, greatly reduce cost and having saved the duration, chassis uses handle to control oil cylinder location steel form, Degree of accuracy is high, and stress is safe and reliable, there is not the race situation such as mould, swollen mould, greatly reduces safe mass hidden danger, to waterproof requirement Higher tunnel structure is advantageously.
Accompanying drawing explanation
Fig. 1 is the front view of open trench tunnel square-section self-propelled mobile falsework chassis.
