Example 4

The present embodiment differs from the previous embodiments in that: an additional layer and a warehouse separating belt are laid before construction.

The lapping method of the additional layer is as follows: dividing a square waterproof coiled material into two parts with the same area along the center line of a group of opposite sides, namely an overlapping part and an overlapped part, overlapping the overlapping part of the rear waterproof coiled material to the overlapped part of the front waterproof coiled material, and connecting the two parts; the strip belt formed by the lapping method is an additional layer, the additional layer is paved at the specified positions of the internal and external corners and other weak positions of the waterproof base surface according to the corresponding standard requirements, the additional layer is equivalent to divide the waterproof base surface into a plurality of parts by once dividing the waterproof base surface, if the divided part area of the waterproof base surface is too large, the cabin dividing belt needs to be paved on the waterproof base surface, the waterproof base surface is further divided into a plurality of smaller parts by the cabin dividing belt, and the smaller parts are paved respectively.

The warehouse dividing belt is also a strip belt formed by lapping a plurality of square waterproof coiled materials, the lapping method of the warehouse dividing belt is the same as that of the additional layer, the warehouse dividing belt is required to be reinforced through a fastening device after being paved, the reinforcing device in the embodiment is a rivet structure, the warehouse dividing belt is reinforced through rivets, the connection firmness is ensured, as shown in figure 5, a base plane is divided into a plurality of parts by the warehouse dividing belt and the additional layer, then the waterproof coiled materials are paved, the methods in the embodiments 1 to 3 can be flexibly selected according to specific construction requirements to lap joint the waterproof layer, finally, the waterproof layers meeting the construction requirements are respectively formed in the plurality of parts divided by the warehouse dividing belt and the additional layer, and due to the separation of the warehouse dividing belt and the additional layer, even if the waterproof layer is damaged, water cannot randomly flow under the waterproof layer, maintenance personnel can conveniently and quickly determine the damaged position, and the warehouse dividing belt can be matched with the lapping method of other embodiments, can effectively promote work efficiency and improve the result of use.

Compared with the lapping method in the prior art, the waterproof layer formed by the lapping method has good use effect, and is particularly illustrated by the following three test examples:

test example 1: testing tensile elongation percentage tests of different lap joint lengths;

experimental materials and equipment: 1.5mm double-sided self-adhesive waterproof roll material, guan Huang crown waterproof materials Limited in Guanghai, Sichuan; electronic universal testing machine, Shanghai Tuofeng apparatus science and technology Limited; microcomputer controlled electronic universal tester, Shanghai Tuofeng science and technology Limited.

Test group a 1: waterproof roll material without lap joint;

test group a 2: waterproof coiled material with lap joint length of 2 cm

Test group a 3: lapping a waterproof coiled material with the length of 5 cm;

test group a 4: lapping a waterproof coiled material with the length of 10 cm;

test samples: the waterproof rolls in the test groups are used as samples, the sizes of the waterproof rolls which can be placed in a tensile testing machine for testing are different, and because the horizontal tensile force and the longitudinal tensile force on the same waterproof roll are different, two samples are taken out of the same waterproof roll for ensuring the accuracy of test data, the central lines of the two samples are perpendicular to each other, and three groups of samples are taken out of each test group for tensile elongation test;

the test results of test group a1 are shown in table 1:

TABLE 1 test results of test group A1

The test results of test group a2 are shown in table 2:

table 2 test results of test group a2

The test results of test group a3 are shown in table 3:

TABLE 3 test results of test group A3

The test results of test group a4 are shown in table 4:

TABLE 4 test results of test group A4

And (3) analyzing test results:

the variables for the above four test groups, designed based on the controlled variable method, were the difference in the length of the overlap, where group a1 demonstrates the tensile properties of the waterproofing membrane itself without any overlap, as can be seen from comparison with other test groups, the tension performance of the waterproof coiled material is better than that of the waterproof coiled material with the overlapped part, while the groups A2-A4 are different in the difference of the overlapping length, because the lapping is objective in the current waterproof layer construction, and the common lapping length in the prior art is 6 cm, namely the lapping length is close to the lapping length set in A3, the numerical values obtained from A1-A4 are compared with each other, so that the borne tension is obviously increased along with the increase of the lapping length, and the elongation at break is also obviously increased, it can thus be seen that the wider the overlap length, the better the tensile properties of the overlapping portion of the web, and of course the greater the loss of overlap.

Test example 2: testing the tensile property of the waterproof layers obtained by different lapping methods:

test group B1: two waterproof layers without lap joint;

test group B2: one layer is not overlapped, and the other layer is provided with two waterproof layers with the width of the overlapped part being 8 cm;

test group B3: two waterproof layers formed by lapping by the method of embodiment 1;

test group B4: the waterproof layer is formed by lapping by the method of embodiment 1, and two waterproof layers with the allowance of 1 cm are reserved on the lapping surface;

test group B5: the waterproof layer is formed by lapping by the method of embodiment 1, and two waterproof layers with 2 cm of allowance are reserved on the lapping surface;

test samples: the waterproof rolls in the test groups are used as samples, the tensile property in the transverse direction and the longitudinal direction of the same waterproof roll is not completely the same, so that in order to ensure the accuracy of test data, two samples are taken out of the same waterproof roll, the central lines of the two samples are perpendicular to each other, and three groups of samples are taken out of each test group for tensile elongation test;

the test results for test group B1 are shown in table 5:

TABLE 5 test results of test group B1

The test results for test group B2 are shown in table 6:

TABLE 6 test results of test group B2

The test results for test group B3 are shown in table 7:

TABLE 7 test results of test group B3

The test results for test group B4 are shown in table 8:

TABLE 8 test results of test group B4

The test results for test group B5 are shown in table 9:

TABLE 9 test results of test group B5

And (4) analyzing results:

when tensile force is applied, because the strength of the waterproof roll is greater than the fastness of the adhesive, on the waterproof layer formed by the waterproof roll, the lap joint part is a weak part on the waterproof layer and can be acted by the tensile force, the test groups B1-B5 are all double-layer waterproof layers, wherein the test group B1 is a double-layer waterproof layer without the lap joint part, and the two layers are connected by the adhesive, so the tensile force performance is the best, and is higher than that of the test groups A1-A4, one layer of the waterproof layer in the test group B2 is provided with the lap joint part, the other layer of the waterproof layer is not provided with the lap joint part, the tensile force performance is poorer than that of the test group B1, the test group B5 is the double-layer waterproof layer spliced by adopting the method of the embodiment 1, the sample intercepted by the test group B5 is a sample block containing the lap joint part, and can be obtained by comparing the sample block with the table 7 adopting the prior art, and the tensile force value and the elongation at break are both higher than the lap joint part of the prior art, therefore, the waterproof layer lapped by the method in the embodiment 1 has good tensile property, and the sample selected by the test group B2 only has one lapping part, while the waterproof layer lapped by the prior art may have two mutually close lapping blocks, and the part has two lapping parts, so that the tensile property is lower, namely the actual tensile property of the waterproof layer lapped by the prior art may be lower, while the waterproof layer lapped by the embodiment 1 completes the laying of two waterproof layers by one-time construction, so that the waterproof layer only has one, namely the part shown by the sample block in the test group B3, thereby deducing that the tensile property of the waterproof layer lapped by the method in the embodiment is better than that of the waterproof layer lapped by the prior art; the test groups B4-B5 are based on the test group B3, and according to the test results of the test groups A1-A4, the tensile performance is increased along with the increase of the overlapping length, so that the tensile performance can be improved by reserving the margin on the basis of the embodiment 1, and a user can flexibly select the margin according to specific working conditions.

In the present invention, the construction steps for realizing the overlapping and the connection method of the overlapping part of the waterproof roll are all methods commonly adopted by those skilled in the art, and the national standard of GB50345-2012 entitled "technical specification for roofing engineering" also has a definite regulation for the construction of the waterproof layer, which is a well-established prior art, and therefore, detailed description thereof is omitted.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
