Description
Technical field
The present invention relates to a kind of construction method of the realm of building construction waterproof roll, specifically
A kind of construction method of waterproof roll material on settlement joint.
Background technology
In our daily construction, designers usually design main building, auxiliary building, general auxiliary building one or both sides are against main building, the present invention is directed to Shi Fu building one side against main building, there is long 42m centre, wide 0.1m, the settlement joint of high 6m, main building F3/B3, foundation ditch dark (15.6m), 20 layers on the ground, auxiliary building B1 (6.80m), 5 layers on the ground, first layer ground main building ± 0.000, auxiliary building-0.8m, auxiliary building starts to construct when main building structure construction to 10 floor, after main building underground external wall waterproof construction completes, main building backfill starts to construct, below backfill construction Dao Fu building bed course, auxiliary building starts to construct, the settlement joint Chu Fu building outer wall of underground structure waterproof construction in main building Yu Fu building is construction difficult problem: operating space is narrow and small, cannot construct, select other waterproof roll, cost is too high.
The construction method traditional for the waterproof roll at settlement joint place is:
Later stage auxiliary building outer wall of basement waterproof roll, due to without operating space, cannot carry out waterproof construction by drawing.Thereby likely cause unit in charge of construction not carry out waterproof construction to this position, for later infiltration has left hidden danger, the later stage makes up suitable difficulty; Or adopt water-repellent paint to replace, but this method will cause the increase of construction cost, and waterproof effect does not have waterproof roll effective.
Summary of the invention
The object of the invention is the many deficiencies for prior art, provide a kind of can meet according to design drawing carry out waterproof construction, can, as the template of auxiliary building outer wall of basement one side, also solve a body of wall formwork difficulty difficult problem simultaneously, the simple waterproof roll material on settlement joint of construction method again
Construction method.
Realize foregoing invention object by the following technical solutions: a kind of waterproof roll material on settlement joint construction method, described settlement joint is between main building Yu Fu building, and the construction method of this waterproof roll material on settlement joint is carried out in the steps below:
A, when main building first floor structure construction pre-buried two rows for the earth anchors of fixing longitudinal steel pipe, two described row's earth anchor spacing are 600mm, first row earth anchor is 300mm apart from structural edge, the spacing of described longitudinal steel pipe is 600mm, longitudinally steel pipe leans out structural edge 300mm, the sub-jam-pack of timber wedge for gap of longitudinal steel pipe and earth anchor, at second row earth anchor, place laterally adds steel pipe one, and horizontal, longitudinal steel pipe intersection connects with cruciform fastening for falsework;
B, when construction auxiliary building foundation pad pre-buried Yi Paifu building earth anchor, the position of auxiliary building earth anchor is corresponding with main building first floor earth anchor position, auxiliary building earth anchor equals settlement joint width apart from the distance of main building exterior wall and deducts waterproof roll thickness and deduct polyphenyl plate thickness again;
C, standing rigging screw-button is installed: at the main building steel pipe leaning out, apart from the front and back position of structural edge spacing, weld respectively 50mm reinforcing bar, wire tensioner is arranged between two reinforcing bars, be positioned at the top of bracing wire, one of described bracing wire ties with wire tensioner, the earth anchor of Yu Fu building, other end foundation pad connects, and the height of the setting space You Fu building basement of wire tensioner and bracing wire is determined;
After D, main building outer wall of basement waterproof coiled material construction, bracing wire is installed, after tension bracing wire, polyphenyl plate is installed, until polyphenyl plate, constructed after acceptance(check), smearing thickness is 10mm adhesive mortar layer, then carries out the external wall waterproof coiled material construction of auxiliary building, topping and auxiliary building structure construction;
After E, auxiliary building underground structure wall construction, remove the horizontal stroke of standing rigging screw-button and main building, longitudinal steel pipe.
As preferred version, described earth anchor is several character form structures.
As preferred version, at the main building steel pipe leaning out, apart from the spacing of structural edge, be that settlement joint width deducts waterproof roll thickness and deducts polyphenyl plate thickness again, before and after this position, weld respectively two grade reinforcing steels of the Φ 14mm that 50mm is high.
Adopt technique scheme, compared with prior art, not only solved the hidden danger that construction stays in earlier stage, solved the difficult problem that constuction joint place body of wall cannot formwork simultaneously, overcome the hidden danger of leaking that construction stays, according to this method, constructed, settlement joint place waterproof effect is remarkable, water-tight, and method is simple, and construction cost is low.
