Description

Technical Field

[0001] This utility model belongs to the field of housing construction technology, and in particular relates to a double π-type connection device for connecting prefabricated partition walls. Background Technology

[0002] Since 2014, the total number of migrant workers in the construction industry has been decreasing year by year, while their average age has been increasing year by year. Currently, most of the workers are over 40 years old, resulting in a serious imbalance in the age structure of migrant workers in the construction industry. The problems of aging and labor shortage are becoming increasingly serious. The emerging prefabricated structure saves construction time, improves construction efficiency, and reduces the demand for labor by simultaneously carrying out factory prefabrication and on-site assembly, thereby effectively solving the problem of labor shortage in the construction industry.

[0003] Currently, U-shaped steel clips are often used to connect prefabricated partition walls, wall panels to floor slabs / beams, and wall panels to structural columns. However, the use of U-shaped steel clips has problems such as low installation efficiency, poor connection stability, and significant seismic risks, which can hardly meet the requirements of modern prefabricated buildings for efficient construction and safety performance. This utility model proposes a double π-shaped connection device for connecting prefabricated partition walls and its usage method to improve the safety and stability of the connection between various structures.

[0004] Therefore, it is necessary to provide a new double-π type connection device for connecting prefabricated partition walls to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a double π-type connection device for prefabricated partition wall connections, which forms a dual force transmission path with accessories such as U-shaped steel plates and rectangular steel bars, can increase the height of the node area, improve the shear bearing capacity and overturning resistance of the connection between the wall panel and the floor / beam, and effectively improve the stability and safety of the connection.

[0006] To solve the above-mentioned technical problems, the present invention provides a double π-type connection device for connecting prefabricated partition walls, comprising: a double π-type connection mechanism for connecting wall panels and floor slabs / beams, wherein the double π-type connection mechanism is composed of rectangular steel bars, two U-shaped steel plates and multiple nails;

[0007] The double π-type connection mechanism is used to improve the connection stability and safety between wall panels and floor slabs / beams.

[0008] As a further embodiment of this utility model, the U-shaped steel plate and the rectangular steel bar are connected and fixed by multiple nails.

[0009] As a further embodiment of this utility model, the space between the wall panel and the floor slab / beam is filled with special mortar.

[0010] As a further embodiment of this utility model, two circular holes are provided on the U-shaped steel plate.

[0011] As a further embodiment of this utility model, the rectangular steel bar is provided with a plurality of circular holes.

[0012] As a further embodiment of this utility model, both the second circular hole and the first circular hole are adapted to the nail.

[0013] Compared with related technologies, the double π-type connection device for connecting prefabricated partition walls provided by this utility model has the following advantages:

[0014] 1. This utility model sets up a double π-type connection mechanism, which consists of two U-shaped steel plates and a rectangular steel bar, forming a dual force transmission path. The π-type connector can increase the height of the node area, improve the shear bearing capacity and overturning resistance of the connection between the wall panel and the floor / beam, and effectively improve the stability and safety of the connection.

[0015] 2. This utility model uses a U-shaped steel plate and rectangular steel strip connected and fixed by multiple nails. The combination of double U-shaped steel plates and rectangular steel strips forms a rigid frame, which can increase the contact area, enhance the node stiffness and load-bearing capacity, and solve the problem of poor stability of traditional U-shaped steel clip connections.

[0016] 3. This utility model not only further enhances the sealing and integrity of the connection by filling the space between the wall panel and the floor slab / beam with special mortar, but also reduces installation errors through the self-adaptive properties of the mortar, effectively solving the shortcomings of traditional U-shaped steel clips that are difficult to operate and easy to loosen.

[0027] Example 1:

[0028] Combination Figure 1 The present invention provides a double π-type connection device for connecting prefabricated partition walls, comprising:

[0029] The double π-type connection mechanism 1 is used to connect the wall panel 2 and the floor slab / beam 3. The double π-type connection mechanism 1 is composed of rectangular steel bars 11, two U-shaped steel plates 12 and multiple nails 13.

[0030] The U-shaped steel plate 12 and the rectangular steel bar 11 are connected and fixed by multiple nails 13.

[0031] The space between the wall panel 2 and the floor slab / beam 3 is filled with special mortar 4.

[0032] The U-shaped steel plate 12 has two circular holes 121.

[0033] The rectangular steel bar 11 has multiple circular holes 111.

[0034] Both the second circular hole 121 and the first circular hole 111 are adapted to the nail 13.

[0035] The double π-type connection mechanism 1 is used to improve the connection stability and safety between the wall panel 2 and the floor slab / beam 3.

[0036] The components of the double π-type connection device, namely rectangular steel bars 11, U-shaped steel plates 12, and nails 13, are inspected to ensure that their quality meets the construction requirements. At the same time, the base layer of the connection parts of the wall 2, floor slab / beam 3 is cleaned to remove impurities and dust, in order to prepare for subsequent connections.

[0037] The installation position of the double π-type connection mechanism is determined by measuring the dimensions with a chalk line. Then, in accordance with the chalk line, the two U-shaped steel plates 12 and the rectangular steel strip 11 are connected and fixed with nails 13 to form the double π-type connection mechanism 1. After that, the assembled double π-type connection mechanism 1 is fixed to the corresponding positions on the structural wall / column 3 and the wall panel 2 respectively.

[0038] Apply special mortar 4 to the tongue and groove joint of wall panel 2, erect wall panel 4, wedge it tightly with wooden wedges, check the horizontal and verticality of the wall surface and fix the panel, so that wall panel 2 is in close contact with double π-type connecting mechanism 1. After wall panel 2 is installed stably, remove the wooden wedges, and use special mortar 4 to fill the gap between wall panel 2 and floor slab / beam 3 for secondary filling and vertical filling, so that double π-type connecting mechanism 1, wall panel 2, floor slab / beam 3 form a whole. Through the force transmission of double π-type connecting mechanism 1 and the bonding and filling effect of special mortar, a stable connection between wall panel 2 and floor slab / beam 3 is achieved.

[0039] Example 2:

[0040] Example 6: A double π-type connection device for connecting prefabricated partition walls according to the present invention includes replacing the floor slab / beam 3 in Example 1 with the structural wall / column A, while other accessories and connection methods remain unchanged.

[0041] The double π-type connection mechanism 1 can be used for connections between prefabricated partition walls, between wall panels and floor slabs / beams, and between wall panels and structural columns, effectively improving the stability and safety of prefabricated partition walls.

[0042] All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings.
