The tunnel inner structure ditch quick detach template include a plurality of steel form, bracing piece, joint connecting plate and joint fixed muscle that the ending docked. This ditch quick detach template passes through bracing piece and the inside steel structural welding in tunnel, can fix firmly in the inside backfill concrete in tunnel, is convenient for demolish moreover, repeatedly usable, and the partly usable job site clout of bracing piece, loss are little, and are with low costs.
Description
Technical Field
The utility model belongs to the technical field of municipal engineering, and particularly relates to a tunnel inner structure ditch quick-dismantling template.
Background
In the electric shield tunnel, in order to meet the use function, the bottom of the tunnel is backfilled by plain concrete, a drainage ditch along the longitudinal direction of the tunnel is arranged in the backfilled concrete, and a drainage ditch template cannot be fixed due to the fact that no reinforcing steel bars exist in the plain concrete. The conventional ditch formwork adopts a wood formwork, and the ditch is small in size (170 x 130 mm), so that the wood formwork is not easy to remove, the loss is large, and the concrete at the edge of the ditch is easy to damage.
How to solve the problems of positioning, fixing and quick dismantling of the ditch template in the backfill plain concrete in the tunnel is a problem which needs to be solved urgently.
Disclosure of Invention
In order to overcome the problems in the background art, the utility model provides the rapid-dismounting template for the ditch of the internal structure of the tunnel, which can be firmly fixed in internal backfill concrete, is convenient to dismount, and has the advantages of simple structure and low cost.
In order to realize the purpose, the utility model is realized by the following technical scheme:
the utility model provides a tunnel inner structure ditch quick detach template, includes steel form, bracing piece, joint connection board and the fixed muscle of joint of a plurality of ending butt joints, the steel form be the slot form, the top sets up the opening, the opening both sides are inwards buckled, the steel form passes through the bracing piece support fixed, the bracing piece lower extreme inserts in the tunnel backfilled concrete to with the welding of the inside steel construction in tunnel, connect through the joint connection board of two "[" shapes between the two adjacent sections steel form, the joint connection board symmetry of two "[" shapes is inlayed the both sides inner wall at steel form butt joint department, the steel form of two sections butt joints respectively stretches out half length parcel in two joint connection board outsides, it is fixed to propping through the fixed muscle of joint between the joint connection board of two "[" shapes.
Further, the bracing piece form through two horizontal reinforcing bars and two vertical steel bar welding, the steel form cartridge is at the middle opening part that two horizontal reinforcing bars and two vertical steel bar enclose, two vertical steel bar insert in the tunnel backfill concrete to with the inside steel construction welding in tunnel.
Furthermore, the support rods are arranged at intervals of 2m along the longitudinal direction of the steel template.
The utility model has the beneficial effects that:
this ditch quick detach template passes through bracing piece and the inside steel construction welding in tunnel, can fix firmly in the inside backfill concrete in tunnel, be convenient for moreover demolish, repeatedly usable, the partly usable job site clout of bracing piece, loss are little, and are with low costs.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below to facilitate understanding of the skilled person.
The utility model provides a tunnel inner structure ditch quick detach template, includes steel form 1, bracing piece 2, joint connecting plate 3 and the joint fixed muscle 4 of a plurality of ending butt joints, steel form 1 adopt the curved slot form of making the required size of ditch of 3mm thick steel sheet, the top sets up the opening, the opening both sides inwards buckle 2cm, demolish the stress point of hanging out as the template. The steel templates 1 are supported and fixed through support rods 2, the support rods 2 are arranged at intervals of 2m along the longitudinal direction of the steel templates 1, the support rods 2 play a role of supporting and fixing the steel templates 1, when concrete is prevented from pouring, the steel templates 1 float upwards and move left and right, the lower ends of the support rods 2 are inserted into tunnel backfilling concrete 6 and are welded with a steel structure 5 in a tunnel, each section of the steel templates 1 is 6-8 m long, two adjacent sections of the steel templates 1 are connected through two [ -shaped joint connecting plates 3, the two [ -shaped joint connecting plates 3 are symmetrically embedded in the inner walls of two sides of the butt joint of the steel templates 1, the two sections of the butted steel templates 1 extend half of the length to wrap the outer sides of the two joint connecting plates 3, 3 joint fixing ribs 4 are arranged between the two [ -shaped joint connecting plates 3, the two joint connecting plates 3 are supported and fixed, and the longitudinal integrity of the ditch steel templates 1 is enhanced, the function of preventing the joint from leaking and deviating is achieved.
This ditch quick detach template passes through bracing piece 2 and the welding of the inside steel construction 5 in tunnel, can fix firmly in the inside backfill concrete in tunnel, be convenient for moreover demolish, repeatedly usable, 2 usable job site clouts of part of bracing piece, loss are little, and are with low costs.
The use process of the utility model is as follows:
before the inside bottom plate of tunnel backfilled concrete placement, target in place this template installation, after the completion of concreting possessed certain intensity, adopted the sledgehammer to strike the solder joint position that 2 top transverse reinforcement of bracing piece and below are connected, dismantled the transverse reinforcement of steel form 1 top, upwards promoted steel form 1 again and extracted, realized that the ditch template is demolishd fast.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
