Abstract
The utility model discloses a temporary cover plate used for construction by a cover-cut method, which is characterized in that a plate body can be a solid core plate or a hollow core plate, the hollow core plate is provided with a long hole, the surface of the plate body is covered with concrete and an asphalt layer. The temporary cover plate overcomes the disadvantage that a crest slab is utilized as a main force bearing structure during the construction in the cover-cut method further to cause the damage of the crest slab, and has an advantage over the safety; the temporary cover plate has unified specification, convenient manufacturing, transportation and assembly, and has more competitive power in appearance and practicability; and the temporary cover plate can be recovered and utilized for a plurality of times, and is more economical.
Description
Technical field:
The present invention relates to the technical field of cap excavation method structure construction, specifically a kind of a kind of interim cover plate that when cap excavation method construction underground structure, uses.
Background technology:
Build fairly large underground constructions such as subway station, underground passage or underground parking in the business district of prosperity, fluting open-cut method can be disturbed traffic over a long time, influence city appearance environment, and is worthless often; And the hidden construction process construction period is longer, and settlement of stratum is big to the adjacent building Influence on security, construction costs is also very high, is not optimum job practices equally.In this case, build earlier the top board of underground structure, then under the screening of top board safety, successfully build underground structure other parts ground cap excavation method often becomes a kind of the best because of safety, suitable and moderate ground construction cost job practices.
But cap excavation method is built earlier the top board of underground structure, and afterwards with the platform of top board as construction or traffic above-ground, often the top board injury to underground structure is very big, the normal use after having influence on top board and building up.
Summary of the invention:
The purpose of this utility model is to provide a kind of interim cover plate that is used for the cap excavation method construction, it can guarantee that underground permanent structure top board is injury-free in work progress, and after construction was finished, interim cover plate can be recycled, save cost greatly, reduced construction costs.
To achieve these goals, technical scheme of the present invention is: a kind of interim cover plate that is used for the cap excavation method construction, and it mainly comprises plate body, it is characterized in that: plate body can be solid slab or hollowcore slab, the hollowcore slab place is provided with slotted hole, and the plate body surface is covered with concrete, bitumen layer.
The utility model discloses a kind of interim cover plate that is used for cap excavation method construction, thus its overcome utilize in the cap excavation method top board as construction period main force structure cause the shortcoming of top board damage, aspect safety, have more advantage; Substitution plate gauge lattice are unified, make things convenient for manufacturing, transportation and assembly unit, and are more competitive on aesthetic property, practicality; It can reclaim, repeatedly utilize, and has more economy.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of another embodiment of the utility model.
The specific embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of interim cover plate that is used for the cap excavation method construction, it mainly comprises card body 1, it is different from prior art and is: plate body 1 can be solid slab or hollowcore slab, the hollowcore slab place is provided with slotted hole 2, the pass of slotted hole 2 can be square, circular, plate body 1 can be concrete material, aluminum alloy material, steel matter, the size of plate body can be long 8000mm * wide 1000mm * high 400mm or long 4400mm * wide 1250mm * high 400mm, its specification adopts international road assembling board size, also can work out suitable specification according to concrete engineering, plate body 1 surface is covered with the 1-100mm concrete, 1-50mm pitch.
The utility model is prefabricated in advance, can splice fast, compare with the construction concrete roof, do not need concrete curing time, can recover the normal operation of traffic above-ground quickly, guarantee that underground permanent structure top board is injury-free, and after construction was finished, interim cover plate can be recycled, save cost greatly, reduced construction costs.
The adoptable concrete grade of concrete slab is C30～C50, and reinforcing bar is HRB335, HRB400, RRB400 and prestressed reinforcement.
Steel can adopt Q235 steel, Q345 steel, Q390 steel and Q420 steel.
