Description

Technical Field

[0001] The present invention belongs to the technical field of light steel structure buildings, and particularly relates to a connecting piece for connecting columns in a steel structure of a light steel house. Background Art

[0002] The light steel structure is a young and highly vital steel structure system, which has been widely applied to general industrial and agricultural, commercial, and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourism buildings, and low- and multi-story residential buildings. Light steel can be understood as a single-story solid-web portal frame structure with a light roof and light exterior walls (masonry exterior walls can also be conditionally adopted). Here, the light mainly refers to the use of lightweight materials for the enclosure.

[0003] Since the main components of light steel buildings are processed in the factory and then assembled on the construction site, it is required that the transportation and installation of various accessories of light steel buildings be very convenient and fast, so as to improve the construction efficiency and shorten the construction time. The inventor found in the actual use process that these existing technologies have problems such as troublesome installation and fixation operations and low efficiency. When building multi-story light steel structure houses, it is necessary to fixedly connect the steel columns of the upper and lower layers. However, there are many steel columns in the upper and lower layers, and the assembly is inefficient and troublesome, which has a significant impact on the construction time and construction difficulty. Summary of the Invention

[0004] To overcome the above deficiencies, the inventor of the present invention through long-term exploration and attempts, as well as multiple experiments and efforts, continuously reformed and innovated, and proposed a connecting piece for installing a light steel house steel structure, which can solve the problems of low efficiency and cumbersome installation in the assembly of steel columns in multi-story light steel structures.

[0005] The technical solution adopted by the present invention to achieve the above object is as follows:

[0006] A connecting piece for installing a light steel house steel structure, which includes an inter-column seat and an inter-column auxiliary seat. A channel for a light steel column to pass through is provided on the inter-column auxiliary seat. The inter-column seat and the inter-column auxiliary seat are assembled in cooperation. A baffle is provided on the inter-column seat. The baffle divides the inter-column seat into upper and lower parts. The upper and lower parts of the inter-column seat are respectively connected to different column bodies. Installation holes are provided on both the inter-column seat and the inter-column auxiliary seat.

[0007] Furthermore: The inter-column seat is a square frame structure. Baffles are installed at the four corners of the inner wall of the inter-column seat. A bayonet is provided on the lower part of the inter-column seat divided by the baffle. The inter-column auxiliary seat is assembled with the inter-column seat through the bayonet.

[0008] Further: The auxiliary seat between columns includes an inner seat partition and an outer seat partition. The inner seat partition and the outer seat partition are of an integral structure. The inner seat partition is sleeved inside the seat between columns, and the outer seat partition is located outside the seat between columns. The auxiliary seat between columns is buckled on the seat between columns through the outer seat partition.

[0009] Further: The number of the outer seat partitions is one or more.

[0010] Further: The connecting end of the outer seat partition and the inner seat partition is a bevel surface, which is fitted and assembled with the seat between columns.

[0011] Further: The inner seat partition of the auxiliary seat between columns is of a regular octagon structure, and its each side is matched with the inner wall of the seat between columns and the side of the baffle.

[0012] Further: The outer seat partition of the auxiliary seat between columns is of a symmetric structure with upper and lower two faces, and is respectively used for connecting the columns above and below.

[0013] Further: The channel is located at the central position of the auxiliary seat between columns.

[0014] Further: The seat between columns and the auxiliary seat between columns are made of galvanized steel plates with a thickness of 3 - 5 mm.

[0015] Further: The installation holes are bolt holes, which are arranged on the side plates of the seat between columns and the auxiliary seat between columns. There are at least two rows of bolt holes distributed from top to bottom at each corner of the seat between columns, with at least two bolt holes in each row. The bolt holes in the upper row are used for fixedly connecting the column above the seat between columns, and the bolt holes in the lower row are used for connecting the column below the column hole, so as to connect the upper and lower two columns into one body.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages / beneficial effects:

[0017] A channel is arranged in the middle of the auxiliary seat between columns of the present invention, and the wall of the channel is higher than the thickness of the inner seat partition of the auxiliary seat between columns. The protruding part is matched with the seat between columns to fix the column, so that the connection effect is more stable.

[0018] The present invention includes a seat between columns and an auxiliary seat between columns. The seat between columns and the auxiliary seat between columns are connected up and down. The upper and lower U-shaped plates and a channel are arranged on the auxiliary seat between columns, and the upper and lower frames and a baffle are arranged on the seat between columns. The lower U-shaped plate is fixedly connected to the auxiliary column in the horizontal direction at the top of the light steel structure, the upper U-shaped plate is fixedly connected to the auxiliary column in the vertical direction of the upper layer of the light steel structure, and the beam passes through the channel, that is, the auxiliary seat between columns fixedly connects the beam, the auxiliary column in the horizontal direction of the lower layer and the auxiliary column in the vertical direction of the upper layer. The lower frame is fixedly connected to the main column in the vertical direction of the lower layer, the upper frame is fixedly connected to the main column in the vertical direction, and at the same time, the seat between columns plays a limiting role on the seat between columns above. Through this connecting piece, the steel columns at the connection of the upper and lower layers can be quickly fixed, and at the same time, the operation is simple, convenient and efficient.

[0019] Meanwhile, in the present invention, as a building fitting, a combined snap - fitting structure is adopted, so the overall volume of the connecting piece during transportation is reduced, making transportation more convenient. At the same time, the installation adopts a snap - fitting method, so it is more convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0027] Example:

[0028] As Figures 1-3 shown, the connecting piece of the present invention is used for the installation of the steel structure of a light - steel house, and the specific structural description is as follows.

[0029] As Figure 1 shown: The connecting piece is composed of two major accessory combinations. The two accessories are: the column base 100 and the auxiliary column base 200. The column base 100 and the auxiliary column base 200 are assembled with each other to form the connecting piece. Mounting holes 300 are provided on the side plates of the column base 100 and the auxiliary column base 200. The mounting holes 300 can be bolt holes, which are mainly used to fixedly connect the columns of the steel structure.

[0030] As Figure 2 shown: The column base 100 is an integral frame structure. In this embodiment, a quadrilateral frame structure is adopted. Then, baffles 101 are installed at the four corners of the inner wall of the frame. The baffles 101 are triangular, and they can be fixed to the column base 100 by welding or other means. They mainly divide the column base 100 into upper and lower parts, and at the same time are used to improve the overall stability of the column base 100. Then, mounting holes 300 are formed by drilling holes on each side of the column base. Among them, two rows of holes are drilled at both ends of each side, respectively located on the upper and lower sides of the baffle, for connecting and fixing the columns at the upper and lower ends; only one row of mounting holes is provided in the middle of each side, located in the upper part. Among them, bayonets 102 are provided at the middle parts of the four sides of the frame. The bayonets 102 are mainly used to install the auxiliary column base 200.

[0031] As Figure 3 shown: The auxiliary column base 200 includes an inner seat partition 203 and an outer seat partition 202. The inner seat partition 203 and the outer seat partition 202 are an integral structure. The inner seat partition 203 is sleeved inside the column base 100, and the outer seat partition 202 is located outside the column base 100. The auxiliary column base 200 is buckled on the column base 100 through the outer seat partition 202. A channel 201 is provided at the center position of the inner seat partition 203. The wall of the channel 201 is higher than the thickness of the inner seat partition 203. Therefore, a protruding hollow column is formed at the upper and lower ends of the inner seat partition 203. In this way, the main column to be installed can pass through the connecting piece through the channel 201. Then, a groove is formed between the part of the channel higher than the inner seat partition and the wall of the column base 100 and the inner seat partition, for installing the column at the upper or lower end. In this embodiment, the shape of the periphery of the inner seat partition 203 corresponds to the shape of the side formed by the column base 100 and its baffle 100. In this way, when installing, the shape of the inner wall formed by each side of the inner seat partition and the inner wall of the column base and the baffle fits, and they can be tightly buckled together.

[0032] At least one outer seat partition 202 is connected around the inner seat partition 203, thus forming the auxiliary seat 200 between columns. The number of the outer seat partitions 203 is determined according to the number and positions of the columns during actual installation. When installing the steel structure, connectors with different numbers of outer seat partitions can be selected according to the actual situation. The overall shape of the outer seat partition is roughly like a drawer shape symmetrical about the upper and lower sides. The upper and lower sides at the end connected to the inner seat partition are both inclined planes, so that the inclined planes cooperate with the bayonet 102 of the seat 100 between columns and can be directly snap-fitted.

[0033] The inner seat partition 203 is a regular octagon, and its vertical length and horizontal width are the same as or smaller than those of the frame. That is to say, the connecting plate can at least pass through the frame. The channel 201 is arranged at the center of the inner seat partition. The channel 2201 is a hollow cuboid. It should be noted that the hollow cuboid is only one type in the present invention, and it can also be a hollow cylinder, etc. That is to say, the channel 201 can also be a tube, which is arranged at the middle position of the inner seat partition to form an integral structure. Of course, it can also be assembled on the inner seat partition, but in this case, the stability of the connector will be slightly worse, but it is convenient to select different channels according to the actual situation and the operation is more flexible.

[0034] The overall shape of the outer seat partition 202 is a drawer structure symmetrical about the upper and lower sides. Specifically, there is a C-shaped plate 205, and a connecting plate 204 is arranged on the C-shaped plate to divide the C-shaped plate 205 into upper and lower parts. The connecting plate 204 is connected to the inner seat partition 203. The end of the C-shaped plate close to the inner seat partition is a conical inclined plane (as shown at A in Figure 3 ). Bolt holes are arranged on the C-shaped plate. The bolt holes are arranged in sequence from left to right at a certain interval on the two side plates of the C-shaped plate. There are two rows or more than two rows of bolt holes, that is, there is at least one row of bolt holes on the two C-shaped plates on the upper and lower sides of the connecting plate, and there are three bolt holes in each row, so that it can be used to connect the columns at the upper and lower ends.

[0035] This connecting seat is applicable to high-rise buildings or multi-story light steel structures, and it can connect the steel columns of the upper and lower layers in high-rise buildings. The materials of the seat between columns and the auxiliary seat between columns are both 3-5 mm thick galvanized steel plates, and their tensile strength is between 80 KN and 120 KN, which enhances the stability between columns and effectively improves the seismic resistance of the house.

[0036] The seat between columns and the auxiliary seat between columns are connected up and down, with the auxiliary seat between columns at the lower part and the seat between columns at the upper part. It should be noted that the seat between columns and the auxiliary seat between columns are spliced up and down in this embodiment, and it is not limited to this form. For example, they can be fixedly connected. Because there is a groove (bayonet) with the opening facing downwards at the contact position between the seat between columns and the auxiliary seat between columns, the side plate of the auxiliary seat between columns can be snapped into the groove upwards, so that the two are connected into one body. When the pressure between the upper and lower columns (steel columns) is greater, the seat between columns and the auxiliary seat between columns are snapped tighter and the safety of the connector is higher.

[0037] Usage method: Build the lower-layer light steel structure. At this time, the main columns are perpendicular to the ground, and multiple main columns are fixed together. There is a beam in the center surrounded by multiple main columns. Vertical auxiliary columns are arranged beside the main columns, and horizontal auxiliary columns are fixedly connected to the tops of the main columns. Adjacent horizontal auxiliary columns are perpendicular to each other (the structural relationship of these columns belongs to the conventional method of building construction). Assemble the column-to-column seat auxiliary seat of the connector on the main beam, snap the column-to-column seat onto the column-to-column auxiliary seat, then align the upper and lower auxiliary columns and install them on the outer partition of the column-to-column auxiliary seat, and then fix the column-to-column auxiliary seat and the auxiliary column with bolts. At the same time, the main beam passes through the channel of the column-to-column auxiliary seat, and the auxiliary beams around the main beam are installed on the inner partition of the column-to-column auxiliary seat, and then fixed to the column-to-column seat with bolts. Through this connector, the steel columns of the upper and lower layers can be quickly connected, with firm fixation, high tensile strength, convenient operation, and improved efficiency.
