Description
Technical field
The present invention relates to the technical field of ground construction, a kind of terrace template system and construction method are referred in particular to.
Background technique
Building superstructure has steel construction and two kinds of concrete structure, and pure steel structure does not need to set up branch on foundation
Support, it is only necessary to meet crane lifting condition;Concrete structure needs set up support frame on foundation.Terrace is applied
Work often carries out after the completion of Superstructure Construction for the protection to terrace surface layer.Under the conditions of subgrade, due to subsurface
Soil it is excessively poor, and be difficult to handle or processing cost is too high, then use structure terrace.From stress, structure terrace is held
The load received, which can first pass to beam or plate and pass to column again, finally passes to pipe pile foundation;Structure terrace way has pipe pile foundation chainless drives knot
Structure terrace and pipe pile foundation have two kinds of contignation terrace, and the present invention is directed to pipe pile foundation flat slab structure terrace.
Because floor construction is the subsequent job of Superstructure Construction, so during Superstructure Construction, it need to be to terrace
Foundation pile is protected.Because subgrade soil property exist thicker mud, it is easily disturbed, tubular pole periphery walk digging machine or
Crane easily leads to deviation of pipe pile, welding point desoldering and other issues.When Superstructure Construction, Normal practice is not excavate ground
Level ground basis, tubular pole top earthing 400-600mm are laid with graded broken stone further according to formal terrace way, bed course are poured, to facilitate top
The construction of structure.After the completion of Superstructure Construction, bed course, cleaning rubble are abolished again, the extra earthwork is transported outward, builds brick tire
Film is drawn and digs stake core, and floor construction is carried out.Therefore cause process more, the problem of waste of material, and it is big to there is investment, long in time limit
The defects of.
Summary of the invention
For this purpose, technical problem to be solved by the present invention lies in overcoming in the prior art, process is more, leads to long in time limit ask
Topic, thus provide it is a kind of effectively shorten the duration, reduce waste of material terrace template system and construction method.
In order to solve the above technical problems, a kind of terrace template system of the invention, including the stake being mounted on terrace tubular pole
Cap loose tool, and the pile cover fetal membrane is fixed on the stake core reinforcing bar on the terrace tubular pole by the first reserved steel bar, wherein institute
The bottom for stating pile cover fetal membrane is rounded, top is square, and the pile cover fetal membrane is located at the upper end of the terrace tubular pole, and described first
Reserved steel bar is extended upwardly to the top surface of the terrace tubular pole by the bottom end of the pile cover fetal membrane.
In one embodiment of the invention, the quantity of first reserved steel bar is multiple, is evenly distributed on describedly
The top surface of level ground tubular pole and surrounding.
In one embodiment of the invention, the circular hole of pile cover fetal membrane bottom is bigger than the diameter of the terrace tubular pole.
In one embodiment of the invention, extend on the pile cover fetal membrane from top to bottom end and reserved equipped with multiple second
Reinforcing bar, and the bottom of second reserved steel bar extends to the top of the terrace tubular pole.
In one embodiment of the invention, the bottom of second reserved steel bar is uniformly distributed along the terrace tubular pole.
In one embodiment of the invention, it is additionally provided on the inner wall of the pile cover fetal membrane along the circumferential direction around the stake
The third reserved steel bar of cap fetal membrane.
The present invention also provides a kind of construction method of terrace template, the terrace template system described in above-mentioned any one into
Row construction carries out backfilling of earthwork, the stake top of compaction in layers to terrace tubular pole after the completion of including the following steps: cushion cap foundation construction
The stake core of the terrace tubular pole is perfused in absolute altitude, and the pile cover fetal membrane made is mounted on to the top of the terrace tubular pole, and makes institute
It states on the stake core reinforcing bar that pile cover fetal membrane is fixed on the terrace tubular pole by the first reserved steel bar;Continue backfill, layering pressure
In fact to terrace bed course bottom, bed course is poured, while blocking the seam between the pile cover fetal membrane and the terrace tubular pole with concrete
Gap.
In one embodiment of the invention, before the stake core of the perfusion terrace tubular pole, the terrace tubular pole is cleared up
Pile crown position.
In one embodiment of the invention, described when pouring bed course, make the top surface of the bed course Yu the pile cover fetal membrane
Concordantly.
In one embodiment of the invention, it after the step S2 is complete, constructs to superstructure.
The above technical solution of the present invention has the following advantages over the prior art:
Terrace template system of the present invention and construction method, the pile cover fetal membrane are fixed on the stake core on the terrace tubular pole
On reinforcing bar, to advantageously reduce backfilling of earthwork, facilitate floor construction, it is ensured that the quality safety of tubular pole, and the pile cover fetal membrane
Bottom it is rounded, to be conducive to for the pile cover fetal membrane being fixed on the terrace tubular pole, the top of the pile cover fetal membrane
