Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roof waterproof construction, and particularly relates to a roof protection layer split joint construction method. BACKGROUND

[0002] In the field of house building, the quality of roof engineering is directly related to the service life and use function of the building. The roof waterproof protection layer as an important barrier of the waterproof system, its construction quality is particularly critical. In order to prevent irregular cracking of the concrete protection layer caused by temperature change, it is usually necessary to set split joints on the protection layer to effectively release the temperature stress. In addition, in order to enhance the integrity and crack resistance of the protection layer, the traditional process usually binds the reinforcement mesh on the waterproof layer, and then pours the concrete, which involves multiple links such as material transportation and on-site binding.

[0003] At present, the traditional method commonly used in the industry is to form split joints by mechanical cutting after the concrete protection layer is poured and hardened. However, this process faces many challenges in practical application. The construction site conditions are complex, and the proficiency of the operators is not the same, which makes it difficult to control the depth of the split joint. If the split joint is too deep, the lower waterproof layer is easily damaged, which destroys the integrity of the overall waterproof system; if the split joint is too shallow, it is difficult to play an effective expansion role, and the protection layer still has the risk of cracking under the action of thermal expansion and cold contraction in seasonal alternation. These quality defects caused by improper construction control not only affect the visual quality of the roof, but also may cause hidden troubles for subsequent leakage. At the same time, the traditional reinforcement and post-splitting process is complicated, which restricts the improvement of construction efficiency to some extent. SUMMARY

[0004] The present application aims to solve the above problems, and provides a roof protection layer split joint construction method for preventing damage to the waterproof system.

[0005] The present application solves the problem by adopting the technical scheme of: A roof protection layer split joint construction method, comprising the following steps: S1: making a split joint unit, which is composed of two parallel extruded division strips and a plurality of soft steel wire ropes parallel to each other, the soft steel wire ropes being located between the two extruded division strips and fixedly connected with the side surfaces of the two extruded division strips; S2: arranging a plurality of split joint units on the roof panel base layer on which the waterproof layer construction has been completed according to the designed interval, orthogonally laying the plurality of split joint units, so that any two adjacent and orthogonal split joint units form a split frame body, and the plurality of split frame bodies combine to cover the entire roof; S3: placing a pressing weight on the top of the arranged extruded division strip to fix the position of the split joint unit; S4: on the base layer of the roof panel arranged with the joint unit, pouring the concrete protective layer, and making the pouring surface of the concrete protective layer flush with the top surface of the extruded partition strip, in the process, the soft steel wire rope replaces the steel mesh function as the reinforcing bar and is embedded in the concrete; S5: removing the pressing weight, and curing the concrete protective layer, the extruded partition strip and the soft steel wire rope are permanently left and embedded in the concrete protective layer.

[0006] The application adopting the technical scheme has the following prominent features compared with the prior art: The application can realize accurate control of the joint depth by synchronously pouring and forming the joint unit with the concrete, and avoids the risk of damaging the waterproof layer or causing the joint failure due to improper depth control in the traditional post-cutting joint process. The method integrates the joint formation and the protective layer reinforcement function, and the soft steel wire rope plays the role of reinforcing bar in the concrete, realizes the reinforcement function, replaces the process of separately binding the steel mesh in the traditional process, simplifies the construction process, and helps to improve the construction efficiency.

[0007] As a preferred, the further technical scheme of the application is: Further, the pressing weight is a concrete block or a metal block, which can provide stable and reliable fixation for the joint unit, prevent displacement during pouring, and ensure the accuracy of the joint position.

[0008] Further, the material of the extruded partition strip is polyethylene, which has good compatibility with the concrete, and the thermal expansion coefficient of the material is different from that of the concrete, which can better adapt to deformation when the temperature changes, and is conducive to maintaining the sealing performance of the joint.

[0009] Further, the poured concrete protective layer is a fine stone concrete protective layer, which has small aggregate particle size and good workability, and is convenient for pouring and forming and obtaining smooth and dense surface quality.

[0010] Further, the pressing weight is placed at the intersection of the frame body to fix, which can strengthen the fixation of the key nodes of the joint network and further improve the overall stability of the joint system during the construction process. BRIEF DESCRIPTION OF DRAWINGS
