Description

Technical Field

[0001] This invention relates to a connection and construction method for the purlins and wall lintels of existing building roofs, belonging to the field of seismic reinforcement technology for masonry structures. Background Technology

[0002] Improperly constructed roofs pose significant safety hazards. In past earthquakes, the most severe damage has been caused by collapsed roofs in residential buildings. Earthquakes have starkly exposed the weak earthquake resistance of these roofs. The causes of most residential collapses are varied: low-strength mortar, lack of ring beams, and poor seismic measures in structural columns all lead to severely insufficient shear capacity in the walls, resulting in horizontal shear failure during earthquakes. However, the most destructive factor is the roof structure. Most residential roofs use a gable roof with purlins and lack independent supporting columns; when the walls collapse, the roof collapses along with them. my country is an earthquake-prone country, and in rural areas, the primary form of damage during earthquakes is often the collapse of the entire roof, causing significant casualties. Summary of the Invention

[0003] This invention proposes a method for connecting and constructing purlins and wall lintels on existing building roofs, which can improve the overall seismic performance of the building, enhance its resilience, and prevent the roof from collapsing.

[0004] The technical solution of the present invention is as follows:

[0005] A connection and construction method for the wall purlins and purlins of existing building roofs, characterized by: including a wall purlin, a key, a post, and purlins; the wall purlin is fitted into the purlin on the gable wall and fixed with a key passing through a pre-drilled hole in the purlin; the key is a round steel metal product; the post is used to assist in supporting the purlin, and the post is fixedly connected to the purlin with a rivet; the rivets are fixed to the post on both sides.

[0006] Furthermore, the wall purlin is a square cold-rolled steel plate with a thickness of 10mm, and the side length of the wall purlin is the diameter of the purlin plus 200mm.

[0007] Furthermore, the key is circular with a diameter of φ20mm.

[0008] Furthermore, the pin length is the purlin diameter plus 60mm.

[0009] Furthermore, the purlin has a pre-drilled hole at an appropriate position on the gable wall for installing a key; the pre-drilled hole is φ22mm.

[0010] Furthermore, the diameter of the nail can be either φ10 or φ12.

[0011] The connection and construction method for the roof wall purlins and purlins of the aforementioned existing buildings shall follow these steps:

[0012] Step 1: Make the wall brackets and keyways, and prepare the post posts and nails;

[0013] Step 2: Drill the pre-drilled holes for the purlins at the corresponding positions according to the design drawings;

[0014] Step 3: Insert the wall bracket into the purlin and secure it with a pin through the pre-drilled hole in the purlin;

[0015] Step 4: Install the support posts and secure them to the purlins with nails;

[0016] Step 5: After all parts are installed and fixed, apply two coats of red lead anti-rust paint and two coats of mixed paint to the steel.

[0017] Beneficial effects:

[0018] The most significant advantage of this invention is that by fixing the roof purlins with wall brackets, pins, and columns, the wall brackets, gable walls, and columns can jointly bear the seismic load, thereby improving the overall seismic performance of the building, enhancing its resilience, and preventing the roof from collapsing.

[0022] For the connection and construction methods of existing building roof wall purlins and purlins, please refer to [link / reference]. Figures 1-2 As shown, the feature is that it includes a wall bracket 1, a key 3, a post 4, and a purlin 2; after the wall bracket 1 is fitted into the purlin 2 on the gable wall 6, it is fixed by the key 3 passing through the pre-drilled hole 7 in the purlin; the key 3 is a round steel metal product; the post 4 is used to assist in supporting the purlin 2, and the post 4 is fixedly connected to the purlin 2 by a nail 5; the nail 5 is fixed to the post 4 on both sides of the post 4 respectively.

[0023] Furthermore, the wall purlin 1 is a square cold-rolled steel plate with a thickness of 10mm, and the side length of the wall purlin 1 is the diameter of the purlin 2 plus 200mm.

[0024] Furthermore, the key 3 is circular with a diameter of φ20mm.

[0025] Furthermore, the length of the pin 3 is the diameter of the purlin 2 plus 60mm.

[0026] Furthermore, the purlin 2 has a pre-drilled hole at an appropriate position on the gable wall 6 for installing the key 3, and the pre-drilled hole 7 of the purlin is φ22mm.

[0027] Furthermore, the diameter of the nail 5 can be either φ10 or φ12.

[0028] The connection and construction method for the roof wall purlins and purlins of the aforementioned existing buildings shall follow these steps:

[0029] Step 1: Make wall bracket 1, key 3, prepare post 4 and nail 5;

[0030] Step 2: Drill the purlin pre-drilled holes 7 at the corresponding positions of purlin 2 according to the design drawings;

[0031] Step 3: Insert the wall bracket 1 into the purlin 2 and fix it with the pin 3 through the reserved hole 7 in the purlin;

[0032] Step 4: Install the melon post 4 and use nails 5 to fix the melon post 4 and the purlin 2;
