Description

Technical Field

[0001] The utility model relates to the technical field of assembled structures, in particular to an installation structure based on steel column foam concrete wall panels. Background Art

[0002] Prefabricated buildings are widely accepted by the public because of their simplicity and ease of installation, light structure and high strength, diverse shapes and more comfortable touch than other metal buildings.

[0003] At present, the columns and beams of prefabricated buildings are generally connected by welding to form the keel skeleton of the building. Figure 1 The figure shows a commonly used welding method, in which each horizontally arranged beam 2 is welded to the circumference of the support plate 11, and the upper column 1 is welded to the upper plate surface of the support plate 11, thereby achieving the installation of the turning point of the keel skeleton. Although the above-mentioned welding method can achieve the connection between the beam 2 and the column 1, it was found during the welding process that due to the large number of welds on the circumference and upper plate surface of the support plate 11, it will cause large welding stress at the weld, which will cause irregular deformation of the support plate 11 and even produce small cracks at the weld. It can be seen that the current welding method will reduce the connection strength between the column and the beam to a certain extent, and therefore it needs to be improved to eliminate potential safety hazards. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides an installation structure for foam concrete wall panels based on steel columns. The present invention can effectively improve the connection strength between the columns and beams, thereby eliminating the safety hazards caused by welding stress.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A mounting structure based on steel column foam concrete wall panels, wherein the beams fixed to the current column are welded to the column body in sequence, and the support plate at the top of the column is separated from and higher than the beams, and the column located above the column is welded to the upper plate surface of the support plate at the top of the column.

[0007] As a further solution of the present invention: a positioning block protruding upward is installed on the upper plate surface of the support plate, and a positioning hole is recessed on the bottom end surface of the column to form a hole pin that cooperates with the positioning block.

[0008] As a further solution of the present invention, the columns, support plates and positioning blocks are integrally formed castings.

[0009] As a further solution of the present invention: a support pin is installed at the column body where the column and the beam are welded, the end of the beam welded to the column is overlapped on the support pin from top to bottom, and a positioning groove for accommodating the support pin is opened at the overlap of the beam; the groove direction of the positioning groove is vertically downward, and the groove end of the positioning groove close to the support pin is an open end.

[0010] As a further solution of the present invention: the axial directions of the support pins are arranged horizontally.

[0011] As a further solution of the present invention: the support pins are arranged in sequence along the circumference of the column.

[0012] As a further solution of the present invention, two positioning grooves are provided at both ends of the crossbeam.

[0013] As a further solution of the present invention, two positioning holes are provided at both ends of the crossbeam.

[0014] As a further solution of the present invention, the column, the support plate, the positioning block and the positioning pin are an integrally formed cast part.

[0015] As a further solution of the present invention: the columns and the beams are both made of steel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the utility model is in use, by increasing the length of the column, the welding point of the crossbeam is moved down to the column body relative to the support plate, thereby avoiding the simultaneous welding of the upper plate surface and the peripheral side of the support plate, thereby reducing the welding stress inside the support plate, and then effectively avoiding cracks in the welding point between the support plate and the upper column, ultimately achieving the purpose of improving welding strength and eliminating safety hazards.

[0018] 2. The present invention adopts the combination of positioning blocks and positioning holes, which can quickly position the two columns, thereby improving the efficiency of construction; at the same time, it can also find the installation position at one time, avoiding repeated adjustments, thereby improving the accuracy of installation.

[0019] 3. The coordination of the positioning slots and support pins in the present invention provides a pre-emptive support for the beam during welding, thereby improving its stability. Furthermore, because the sizes and positions of the positioning slots and support pins are pre-set according to relevant standards, the coordination of the support pins and positioning slots also serves as a pre-positioning mechanism, enabling accurate installation positioning in one go, eliminating repeated adjustments and improving installation accuracy.

[0020] 4. The columns, support plates, positioning blocks and positioning pins in the present invention are integrally formed castings, which can eliminate the welding stress generated when the columns, support plates, positioning blocks and positioning pins are fixed together by welding, thereby improving the integrity of the structure.

[0021] 5. In the present invention, two positioning grooves are used at one end of the beam, which can form a four-point support positioning for the beam under the action of the support pin, thereby preventing the beam from flipping and falling, and improving the stability of the beam during the welding process.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 3 , the utility model is relative to Figure 1The existing technology mainly changes the column 1. The length of the column 1 in the present invention is about 1.1 times the length of the conventional column 1, and the main body of the column 1 is hollow, that is, the hollow cavity constitutes the positioning hole 14. In actual use, first build the foundation according to the construction drawings. After the foundation is built, the keel frame is installed. In the process of installing the first layer of keel frame, the column 1 in the present invention is used, and the column 1 of the present invention is installed in the corresponding installation point in turn and fixed by welding. Then the crossbeam 2 is overlapped between two adjacent columns 1, so that the positioning groove 21 and the support pin 13 are embedded together up and down, and the distance between the two columns 1 is equal to the length of the crossbeam 2, and then the two ends of the crossbeam 2 are welded, and the crossbeam 2 is fixed between the two columns 1. After the first layer of keel frame is welded in the above-mentioned way, the upper layer of keel frame is welded. When welding other keels, the length of the column 1 used is the conventional length. Because the height of each floor is the same, based on the growth of the first-floor columns 1, the increased length will be transferred upward in the subsequent installation process of the columns 1, that is, the support plate 11 of each floor will be higher than the position of the beam 2 of that floor.

[0028] During the process of welding and assembling the keel frame, the corresponding wall panels 3 are installed simultaneously, thereby forming an assembled building.
