Abstract
The utility model discloses a cover board used in building construction, in particular to a cover excavation method cover board. The utility model comprises a main body of the cover board and a polyurethane layer compounded on the top of the main body; the main body comprises a plurality of H profiled bars which are welded together; margin of the cover board main body is provided with a sealing steel plate; the four corners of the top surface of the top part of the cover board are provided with a hoist hole; and the lower surface of the cover board is provided with a buffering sheet. Although the utility model needs a relative large first investment for the cover excavation method construction, the cover board can be used repeatedly to lower the practical investment cost of the cover excavation method; moreover the cover excavation method construction can maintain the traffic status of the present road and is more applicable to the foundation ditch project of the developing of the underground space of the city.
Description
Technical field
The utility model relates to a kind of cover plate, relates in particular to a kind of construction techniques---the cover plate that uses in the cap excavation method.
Background technology
Along with the development in city, the underground space is in the stage of high speed development at present, and engineering quantities such as subway station, tunnel increase just gradually.The contradiction that how to solve underground space construction and business district urban traffic becomes present one big research topic.Cap excavation method advantage such as can repeatedly use because of having construction period to the little and pavement system of traffic impact, is more and more adopted by vast building unit, therefore designs a kind ofly can satisfy the cover plate that cap excavation method constructs and become the critical component that cap excavation method is constructed.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of safe and reliable, cap excavation method cover plate that can reuse and can keep road traffic condition in the cap excavation method work progress, to satisfy cap excavation method construction needs.
The technical scheme of the utility model technical solution problem is as follows:
A kind of cap excavation method cover plate, it is characterized in that, comprise cover plate main body and the layer of polyurethane that is compounded in the cover plate main body end face, described cover plate main body adopts a plurality of H shaped steel to be welded to each other formation, the shutoff steel plate is set around the cover plate main body, described cover plate upper top is provided with hole for hoist for four jiaos, and the cover plate bottom face is fixed with the damping pad.
By above disclosed technical scheme as can be known, the utility model forms cover plate main body by adopting H shaped steel by high-frequency welding, and the floor that utilizes shaped steel self is as the cover plate floor, and is rational in infrastructure, safe and reliable; By end face composite polyurethane layer on cover plate main body, character such as its pull resistance, wear-resisting wiping and extensibility all can meet the demands in addition.
Though it is bigger in the cap excavation method cover plate fund input first of constructing, but cover plate can reuse, and makes cap excavation method actual investment cost reduce greatly, and the cap excavation method construction can be kept present road traffic condition, obvious social benefit is specially adapted to the base pit engineering that urban underground space is developed.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～3, the utility model cap excavation method cover plate, comprise cover plate main body 1 and the layer of polyurethane 2 that is compounded in cover plate main body 1 end face, described cover plate main body 1 adopts a plurality of H shaped steel 101 to be welded to each other formation, shutoff steel plate 3 is set around the cover plate main body 1, described cover plate upper top is provided with hole for hoist 4 for four jiaos, and the cover plate bottom face is fixed with damping pad 5.
The thickness of described layer of polyurethane is 2～3mm.
Described H shaped steel specification is 166 * 200 * 6 * 8mm, makes the cover plate planar dimension reach 3 * 1m by the H shaped steel that adopts the specification of stipulating, is convenient to the standardization of cover plate.
Described cover plate bottom face also is fixed with spacing angle steel 6.
The cap excavation method support system can adopt primary and secondary beam linked system, and cover plate is shelved on the secondary beam.The first road of ultra-deep foundation pit supports the concrete that adopt more and supports, and secondary beam is selected girder steel.The freely-supported form is adopted in connection between the primary and secondary beam.Shelve secondary beam place cast-in fixing bolt at girder, secondary beam is fixed, then the cover plate freely-supported is shelved on the foundation ditch secondary beam, and damping pad 5 is set by steel plate, thus the safety and comfort of assurance vehicle pass-through.Can also be by angle steel spacing 6 be set on the cover plate bottom face, and the yielding rubber pad 5 of cushioning effect has been set in angle steel side and cover plate bottom, thereby cover plate is shelved on the secondary beam, consider that in addition automobile travels along the steel plate short side direction in the engineering, there is interaction force between the cover plate, may produce laterally and move, therefore can per 10 cover plates it be one group, by connector 7 between a Z-shaped plate is set, with bolt cover plate bottom flange 102 is connected (as shown in Figure 5) with secondary beam 9, connector 7 sides are provided with yielding rubber sheet 5 between Z-shaped plate.For ease of the lifting of cover plate, can offer technology square hole 8 in the cover plate side as shown in Figure 4 in addition.
