Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a parapet wall cap construction method for a connection between a new and an old factory building. Background Art

[0002] In order to effectively avoid the impact of factory building settlement on the parapet wall structure, expansion joints are generally set at the parapet wall at the junction of the new and old factory buildings of the steel structure system. However, considering the problem of waterproofing the cap, the original cap must be removed and remade into a whole. In addition to being affected by the climate and factory building structure settlement, the material must be cut to the required length according to the deviation of the parapet wall structure on both sides, which increases the difficulty of the production process and also affects the overall installation. At the same time, this node is prone to becoming a leakage point.

[0003] In summary, the prior art still lacks a parapet cap construction method with high installation strength and little impact on the original building. Summary of the Invention

[0004] The invention provides a parapet wall cap construction method for the connection between new and old factory buildings, which has high installation strength and little impact on the original building.

[0005] To achieve this object, the present invention provides the following technical solutions:

[0006] The present invention provides a method for constructing a parapet cap at the connection between a new and an old factory building, comprising the following steps:

[0007] S1. Install new parapet panels, structural purlins, and parapet panel trimming. The new parapet panels are set on one side of the old parapet panels, with a gap between the new and old parapet panels. Trim the parapet panels on top of the new parapet panels, and install structural purlins on the new parapet panels, close to the old ones.

[0008] S2. Install the support adjustment piece, install the support adjustment frame on the structural purlin, and measure and maintain the distance between the support adjustment piece and the old parapet board;

[0009] S3. Install a new flashing cap. Install the new flashing cap on the support adjustment member, and connect one end of the new flashing cap to the flashing cap of the old parapet board, and the other end of the new flashing cap to the end of the support adjustment member.

[0010] Preferably, in step S3, the new flashing cap is inserted between the old flashing cap and the old parapet, and the new flashing cap, the old flashing cap and the old parapet are fixed by a connecting piece.

[0011] Preferably, the connecting member includes a waterproof rivet.

[0012] Preferably, in step S2, the support adjustment member and the structural purlin are connected using self-tapping screws.

[0013] Preferably, in step S3, the new flashing cap and the old flashing cap / support adjusting member are connected by using waterproof rivets.

[0014] Preferably, there are multiple self-tapping screws, and the spacing between the multiple self-tapping screws is 15-25 cm.

[0015] Preferably, the support adjustment member is stepped. Further preferably, the support adjustment member comprises, from left to right, a first horizontal plate, a first vertical plate, a second horizontal plate, and a second vertical plate, wherein one horizontal plate is inclined at 5°-10° to the horizontal plane, the second horizontal plate is horizontal, and the first and second vertical plates are both perpendicular to the horizontal plane.

Furthermore, the present invention is simple in construction, enabling mass production and avoiding the cumbersome process of custom-sizing, enabling the rapid and efficient construction of steel parapet cap nodes.

[0018] Compared with the prior art, the present invention has the following beneficial effects and significant improvements:

[0019] 1. The present invention provides a method for constructing a parapet cap at the junction of new and old factory buildings. The method has simple and convenient construction and processing, does not require dismantling the original factory cap, does not affect the normal use of the original factory building, and is easy to install.

[0038] A method for constructing a parapet cap at the junction of a new and an old factory building, comprising the following steps:

[0039] S1. Install new parapet panels, structural purlins, and parapet panel trimming. The new parapet panels are set on one side of the old parapet panels, with a gap between the new and old parapet panels. Trim the parapet panels on top of the new parapet panels, and install structural purlins on the new parapet panels, close to the old ones.

[0040] S2. Install the support adjustment piece, install the support adjustment frame on the structural purlin, and measure and maintain the distance between the support adjustment piece and the old parapet board;

[0041] S3. Install a new flashing cap. Install the new flashing cap on the support adjustment member, and connect one end of the new flashing cap to the flashing cap of the old parapet board, and the other end of the new flashing cap to the end of the support adjustment member.

[0042] In this embodiment, in step S3, the new flashing cap is inserted between the old flashing cap and the old parapet, and the new flashing cap, the old flashing cap and the old parapet are fixed by a connecting piece.

[0043] In this embodiment, the connecting member includes a waterproof rivet.

[0044] In this embodiment, in step S2, the support adjustment member and the structural purlin are connected using self-tapping screws.

[0045] In this embodiment, in step S3, the new flashing cap and the old flashing cap / support adjusting member are connected using waterproof rivets.

[0046] In this embodiment, there are multiple self-tapping screws, and the spacing between the multiple self-tapping screws is 15-25 cm.

[0047] In this embodiment, the support adjustment member is stepped.

[0048] In this embodiment, the new flashing cap is stepped.

[0049] In summary, the method of this embodiment pre-installs the parapet structure, color-coated steel plates, and the color-coated steel trim of the parapet. By measuring the distance from the existing parapet to the support adjustment components, the support adjustment components are uniformly installed and secured according to the drawing requirements before the installation of the new parapet flashing cap begins. This method of this embodiment has a simple structure, low prefabrication difficulty, minimizes labor costs, and effectively meets architectural design and construction requirements. The independently installed support adjustment components can accommodate the impact of typhoon weather on this type of structure, effectively addressing the impact of climate on the parapet cap's inherent strength when the parapet cap has large dimensional deviations.
