Technical Field

[0001] The utility model relates to an arch plate roof, in particular to a steel partition reinforced concrete arch plate roof structure. Background Art

[0002] The arch roof truss consists of an upper chord, a lower chord and vertical partitions. This structure combines the roof panel and the roof truss into one, and has the advantages of good overall performance, light weight and good seismic resistance.

[0003] The most common structural form of the partition is the prefabricated reinforced concrete partition. When the concrete partition is prefabricated, steel bars are reserved at the top and bottom, and reinforcing steel bars are added to the connection between the partition and the upper and lower chords of the arched roof truss. Prefabricated reinforced concrete partitions have the problems of thin plate components (generally 60mm thick), limited load-bearing capacity, long production and construction period, high labor costs, and the slightest collision during the installation process can easily damage the components, affecting their structural performance. Utility Model Content

[0006] The connecting member includes an inner bottom plate, an outer bottom plate, anchor bars and a connecting plate. The inner bottom plate and the outer bottom plate are parallel to each other and connected by a plurality of anchor bars. There are two connecting plates, which are parallel to each other and vertically arranged on the surface of the outer bottom plate. Bolt holes are arranged on the connecting plates.

[0007] Ear plates are respectively arranged on both sides of the column, and a diagonal tie rod is arranged between the columns of two adjacent steel partitions.

[0008] A plurality of upper connecting protrusions are arranged on the lower side surface of the upper chord, a plurality of lower connecting protrusions are arranged on the upper side surface of the lower chord, and the connecting members are arranged inside the upper connecting protrusions and the lower connecting protrusions.

[0009] The upright column is an I-beam, and the web of the I-beam is inserted between the two connecting plates.

[0010] The connecting rod is arranged horizontally.

[0011] One of the steel partitions includes two connecting rods, which are respectively located at the upper and lower ends of the steel partition.

[0012] The utility model uses a steel partition with a simple structure to replace the traditional reinforced concrete partition. The steel partition is made of welded steel sections and can be mass-produced in the factory. Since there is no need to tie steel bars, pour concrete, and maintain concrete, it can save labor costs and production cycles.

DETAILED DESCRIPTION

[0021] like Figure 1 , Figure 2 As shown, the reinforced concrete arch roof structure with steel partition 3 of the utility model comprises an upper chord 1, a lower chord 2 and a steel partition 3.

[0023] like Figure 2 As shown, the steel partition 3 includes two vertically arranged columns 3-1, and the two columns 3-1 are connected by a connecting rod 3-2. The columns 3-1 and the connecting rod 3-2 form a frame structure. The columns 3-1 and the connecting rod 3-2 are both made of steel profiles, and the frame structure has a strong structural strength. The upper and lower ends of the column 3-1 are connected to the connecting piece 6. The steel column 3-1 has a strong load-bearing capacity. The connecting rod 3-2 connects the two columns 3-1, which can prevent the deformation of the steel partition 3 and improve the overall strength and rigidity of the steel partition 3.

[0024] The connecting rod 3-2 is arranged horizontally, and there are at least two connecting rods 3-2 in a steel partition 3. The two connecting rods 3-2 are located at the upper and lower ends of the steel partition 3, thereby forming a U-shaped structure with the two columns 3-1. More columns 3-1 can also be added between the two columns 3-1 to improve the overall structural strength of the steel partition 3.

[0025] The column 3-1 can be a profile such as an I-beam, a channel steel or an angle steel. Optimally, the column 3-1 is an I-beam, the web of which is used to connect with the connector 6, and the side plate of which is used to connect with the connecting rod 3-2.

[0026] like Figure 3 , Figure 4 As shown, the connecting member 6 includes an inner bottom plate 6-1, an outer bottom plate 6-2, anchor bars 6-4 and a connecting plate. The inner bottom plate 6-1 and the outer bottom plate 6-2 are parallel to each other and connected by a plurality of anchor bars 6-4. There are two connecting plates, which are parallel to each other and vertically arranged on the surface of the outer bottom plate 6-2. Bolt holes are arranged on the connecting plates.

[0027] like Figure 5 , Figure 6 As shown, during construction, the inner bottom plate 6-1, anchor bars 6-4 and outer bottom plate 6-2 are cast in the upper chord 1 or the lower chord 2 to fix the connector 6, and the two connecting plates on the connector 6 are exposed from the lower side of the upper chord 1 or from the upper side of the lower chord 2 to facilitate connection with the column 3-1.

[0028] A plurality of upper connection protrusions 4 are provided on the lower side of the upper chord 1, a plurality of lower connection protrusions 5 are provided on the upper side of the lower chord 2, and a connection piece 6 is provided inside the upper connection protrusion 4 and the lower connection protrusion 5. The web of the I-beam structural column 3-1 is inserted between the two connection plates, and a high-strength bolt 9 is passed through the two connection plates and the web of the I-beam, and the nut is tightened to fix the connection piece 6 to the column 3-1.

[0029] The cross-sections of the upper connecting protrusion 4 and the lower connecting protrusion 5 are trapezoidal, and the outer bottom plate 6 - 2 of the connecting member 6 is located on the top surface of the trapezoid.

[0030] In order to increase the overall structural strength of the arch roof structure, ear plates 7 are respectively provided on both sides of the column 3-1, and a diagonal brace 8 is provided between the columns 3-1 of two adjacent steel partitions 3, and both ends of the diagonal brace 8 are connected to the ear plates 7 on the columns 3-1.

[0031] The diagonal tie rod 8 is specifically an angle steel, and the end of the angle steel is fixedly connected to the ear plate 7 by bolts.

[0032] The utility model uses a steel partition 3 with a simple structure to replace the traditional reinforced concrete partition. The steel partition 3 is made of welded steel sections and can be mass-produced in a factory. Since there is no need to tie steel bars, pour concrete, or maintain concrete, labor costs and production cycles can be saved.

[0033] The steel partition 3 has a simple structure, light weight, and strong load-bearing capacity, and its structural strength is higher than that of the traditional reinforced concrete partition. At the same time, since the steel partition 3 is not provided with concrete, even if a collision occurs during transportation and installation, it will not cause damage to the partition, and will not affect the performance and quality of the partition component.

[0034] The construction method of the utility model is as follows.

[0035] Step 1: First, calculate the load of the entire arched roof and determine the structural form and model of the steel partition 3.

[0036] Step 2: issue a design drawing, contact a steel component processing factory, finalize the production of the steel partition 3, and transport it to the construction site after production.

[0037] Step three, installation of steel partition 3: A. Mark the partition control line on the bottom formwork of the lower chord 2 of the arch roof, install the connecting piece 6 of the steel partition 3 on the lower chord 2, and assemble the steel partition 3 in the spans below; B. Lay the prestressed steel bars of the lower chord 2 and tension the prestressed steel bars; immediately after the tensioning is completed, tie the distribution bars of the lower chord 2; C. Hoist the steel partition 3 assembled in the spans onto the connecting piece 6 for installation and fixation. After the installation is completed, install and fix the arch bottom formwork of the upper chord 1 on the steel partition 3.

[0038] Step 4: Lay the upper chord 1 steel mesh and fix the steel partition 3 through the connecting piece 6.

[0039] Step 5: pour the concrete for the arch roof, first the lower chord 2 and then the upper chord 1. The lower chord 2 is poured from the middle of the span to both ends, and the upper chord 1 is poured from both ends to the middle of the span. After the pouring is completed, an integral arch roof is formed.

[0040] After the steel partition 3 is adopted, the overall weight of the reinforced concrete arch roof structure is reduced while the structural strength is improved. By applying this structural form, after the lower chord 2 template is installed in place, the steel partition 3 can be directly installed, which is not limited to the prefabrication and maintenance of the concrete partition in advance, reducing the damage rate during the installation process, greatly improving the installation efficiency, providing a strong guarantee for shortening the construction period, and further ensuring the construction quality and safety in later use. It avoids the common quality problems and quality issues caused by concrete pouring during the partition construction process, saving a lot of labor costs.
