Abstract

The utility model relates to a waterproof roll metal strip reducing opening structure which relates to the technical field of construction. The waterproof roll metal strip reducing opening structure comprises an L-shaped metal strip, wherein the L-shaped metal strip comprises a horizontal part and a vertical part which is vertical to the horizontal part, a cutting seam is formed on or above a waterproof roll laying height control line of a parapet and positioned on a same plane of a waterproof roll reducing opening surface, the horizontal part of the L-shaped metal strip is embedded into the cutting seam, and the vertical part of the L-shaped metal strip compresses a waterproof roll reducing opening on the inner side of the cutting seam. The waterproof roll metal strip reducing opening structure further comprises a fixing device for enabling the L-shaped metal strip to stably press the waterproof roll reducing opening. The waterproof roll metal strip reducing opening structure has the advantages improved roof waterproof roll reducing opening construction quality, ensured roof water resistance, simplified construction processes, smooth roll reducing opening surface and straight horizontal line.

Description

A kind of waterproof roll metal bead closing-in structure

Technical field

The utility model relates to technical field of building construction, especially a kind of waterproof roll metal bead closing-in structure.

Background technology

Traditional roof waterproof coiled material closing in way is to dig out the groove 6 of wide 60mm, dark 60mm at parapet of roofing 5, uses the steel nail stickfast after waterproof roll 7 pavings in groove, uses the floating groove of mortar behind the ointment filleting, as shown in Figure 4 again.This prior art weak point: 1, the conventional grooves formula closes up and can damage the parapet structure, and mortar and the ointment at groove benefit slurry place are non-caked, under the outdoor environment that exposes to the sun and rain, easily cause groove to mend slurry place hollowing, shrinkage cracking or come off, cause closing in place steam invasion coiled material, cause the coiled material hollowing, rainwater infiltrates the coiled material bottom to body structure surface, and the water-proof function of coiled material was lost efficacy in advance; 2, the both sides body of wall requires to plaster first about the groove, fills up groove after the waterproof coiled material construction is finished again, and easily causes surface irregularity, the not straight mass defect that affects impression that waits of horizontal direction; 3, working procedure is many, and the construction convenience is poor, and efficient is low.

The utility model content

The purpose of this utility model provides a kind ofly can improve construction quality that the roof waterproof coiled material closes up, guarantee roofing do not seep water and also simplified working procedure, reached coiled material closing in surfacing, waterproof roll metal bead closing-in structure that the lines level is straight.

The technical scheme that the utility model adopts for achieving the above object is: a kind of waterproof roll metal bead closing-in structure, this waterproof roll metal bead closing-in structure comprises the L-type metal bead, the L-type metal bead comprises horizontal part and the vertical portion vertical with horizontal part, side is provided with one and is positioned at the joint-cutting of same level face with waterproof roll closing in face on the waterproof roll paving of parapet height control line or waterproof roll paving height control line, the horizontal part of L-type metal bead is embedded in the joint-cutting, close up waterproof roll and be pressed on its inboard in the vertical portion of L-type metal bead, described waterproof roll metal bead closing-in structure also comprises the fastening devices of the firm compression waterproof roll closing in that makes the L-type metal bead.

Further technical scheme of the present utility model is: described fastening devices comprise fixing vertical portion the tapping screw on the parapet and be coated in the joint-cutting mouth and the L-type metal bead on weather proofing sealant.

Because adopt said structure, the waterproof roll metal bead closing-in structure of the utility model has following beneficial effect:

1, compares with the closing in of conventional grooves formula, the phenomenons such as ftractureing, aging can not appear in closing in place of embedded waterproof roll anti-backwater metal bead, prevented that rainwater from pouring in down a chimney drawback in the waterproofing course from the coiled material closing in, avoided waterproof roll closing in place the common quality defects such as hollowing, infiltration to occur, guarantee construction quality, reduced and reprocessed probability;

2, adopt this waterproof roll metal bead closing-in structure easy for installation, quick construction need not destroyed structure, when guaranteeing waterproof roll closing in quality, has realized coiled material closing in effect neat, attractive in appearance;

3, adopt this waterproof roll metal bead closing-in structure can effectively increase the application life of waterproof roll, the more conventional groove type closing in practice is more simple on technique, and efficiency of construction is higher, and financial cost is also more cheap.

Below in conjunction with drawings and Examples the utility model waterproof roll metal bead closing-in structure is described further.

Drawing reference numeral explanation: 1-parapet, 2-waterproof roll, 3-joint-cutting, 4-L-type metal bead, 41-horizontal part, 42-vertical portion.

The specific embodiment

As shown in Figure 1 to Figure 3, the utility model waterproof roll metal bead closing-in structure, this waterproof roll metal bead closing-in structure comprises L-type metal bead 4, L-type metal bead 4 comprises horizontal part 41 and the vertical portion 42 vertical with horizontal part 41, horizontal part 41 hem width 20mm, vertical portion 42 hem width 30mm, side is provided with one and is positioned at the joint-cutting 3 of same level face with waterproof roll 2 closing in faces on the waterproof roll paving of parapet 1 height control line or waterproof roll paving height control line, and it is cut surface on the waterproof roll that waterproof roll 2 closes up.The horizontal part 41 of L-type metal bead 4 is embedded in the joint-cutting 3, close up waterproof roll 2 and be pressed on its inboard in the vertical portion 42 of L-type metal bead 4, described waterproof roll metal bead closing-in structure also comprises the fastening devices of firm compression waterproof roll 2 closing ins that make L-type metal bead 4.In the present embodiment, described fastening devices comprise fixing vertical portion 42 the tapping screw on the parapet 1 and be coated in the joint-cutting mouth and L-type metal bead 4 on weather proofing sealant.

In work progress, can finish according to following step: 1. waterproof roll paving height control line setting: according to drawing and code requirement, parapet after plastering is established an absolute altitude control point, this control point height is that the roof panel peak vertically up measures 250mm, with the height at this control point parapet eject one continuously, the waterproof roll paving height level control line of sealing; 2. paving waterproof roll: waterproof roll carries out paving by designing requirement, and its paving highly must meet or exceed more than the waterproof roll paving height control line; 3. eject a horizontal control line on waterproof roll surface, the height of this horizontal control line with 1. the waterproof roll paving of annotating highly control line is identical; 4. joint-cutting: the horizontal control line that ejects on the waterproof roll with cutting machine cuts, and depth of cut 〉=20mm stitches wide 2～3mm; 5. embed the L-type metal bead along seam, L-type the metal bead thick galvanized steel plain sheet of 1mm or aluminium sheet punch forming, the L-type metal bead, horizontal part embeds in the seam, the vertical portion compresses coiled material and closes up, tapping screw with φ 3mm is fixed, and after then compressing sealing and playing glue and process, can play the effect of coiled material closing in anti-backwater; 6. beat weather proofing sealant and carry out gap closing: the slit between L-type metal bead and the floated coat, between tapping screw and the metal bead, all need beat weather proofing sealant and seal, pour within the waterproof roll along the slit to prevent rainwater; 7. playing glue tints: metal bead fixedly tapping screw is beaten weather proofing sealant and is sealed, then the surface can according to decorate required increase to mix colours brush, form the beautifying and decorating line one.
