Description

Technical Field

[0001] This utility model belongs to the field of steel structure building technology, and specifically relates to a prefabricated lightweight steel structure factory frame. Background Technology

[0002] Steel structures are the preferred building material for modern factories and workshops because they improve construction efficiency and are lighter than concrete. Steel structure factory buildings typically consist of columns, beams, supporting columns, purlins, etc.

[0003] A search revealed two existing steel structure factory building construction schemes: a prefabricated lightweight steel structure factory building (CN222413426U) and an integrated prefabricated steel frame factory building (CN215520213U). These schemes offer relatively lightweight structures and faster construction speeds through prefabrication. However, under the requirement of structural stability, if the span of the steel structure factory building in the width direction is large, the stability of the connection method between the beams and columns is relatively low. For example, in the second scheme (CN215520213U), the support at the ends of the supporting crossbars is a mounting plate. Relying solely on the mounting plate for support and fixation is insufficient in terms of load-bearing capacity and stability for supporting crossbars with larger spans. To address these shortcomings, the use of supporting stiffeners is typically employed to improve stability and support effect. For instance, a steel structure support device (CN222595641U) improves the stability between steel columns and beams through a support mechanism.

[0004] Based on the above-mentioned existing technologies, this solution provides a steel structure factory frame. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a prefabricated lightweight steel structure factory frame. The support mechanism can improve the stability and support effect between the first crossbeam and the column. The application of the adjustment component can adjust the position of the first crossbeam on the support base for quick installation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated lightweight steel structure factory frame includes columns, a first crossbeam, a second crossbeam, a support column, a support mechanism, and a third crossbeam. Several sets of columns are provided. The two ends of the first crossbeam are fixedly connected to the columns by bolts. One end of the support column is fixedly connected to the first crossbeam by bolts, and the third crossbeam is fixedly connected to the top of the column by bolts. The support mechanism is fixedly connected to the columns and the first crossbeam by bolts. The second crossbeam is fixedly connected to the top of the support column by bolts, and purlins are provided between the third crossbeam and the second crossbeam, fixed by bolts.

[0008] The support mechanism includes a fixed base, a first support arm, a second support arm, connecting rods, a fixing block, and a bidirectional screw. One end of the second support arm is hinged to the fixed base, and the fixed base is bolted to the first crossbeam. One end of the first support arm is hinged to the fixed base, and the fixed base is bolted to the column. The first support arm has a mounting groove, and connecting rods are hinged on both sides of the first support arm. One end of the second support arm has a fixedly connected insert arm, which inserts into the mounting groove. The insert arm has a through groove, and connecting rods are hinged on both sides of the second support arm. A pair of fixing blocks are provided on both sides of the insert arm, and the ends of the connecting rods are hinged to both ends of the fixing blocks. The bidirectional screw is connected to the fixing block through a bidirectional thread, and the bidirectional screw passes through the through groove.

[0009] Furthermore, the column is provided with a pair of symmetrically arranged support seats, which can be bolted to the upper and lower surfaces of the first crossbeam to improve the stability of the support.

[0010] Furthermore, the column is equipped with adjustment components on both sides to position and adjust the first crossbeam during installation, facilitating rapid installation. The adjustment components include a lead screw, a plug, and a mounting plate. The mounting plate is fixed on the column and has a limiting groove. The plug has limiting plates on both sides. The lead screw is threaded to the plug, which is inserted into the limiting groove and fits into itself. The limiting plates are located on both sides of the mounting plate for limiting.

[0011] Furthermore, the ends of the second crossbeam, support column, and upright column are equipped with fixing plates to facilitate installation and fixation;

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1) The support mechanism is equipped with a bidirectional screw and a threaded fixed block. When the bidirectional screw is rotated, the fixed block will be pulled to move. The fixed block will pull the connecting rod to move. In turn, the connecting rod will push the first support arm and the second support arm to separate at both ends or converge in the middle to adjust the overall length. This allows the fixed seat to be accurately installed on the reserved mounting holes of the first crossbeam and the column. Even if the height of the mounting hole position deviates, it can still ensure smooth installation. This avoids the disadvantage that the length of the conventionally cut and shaped rib plate material is insufficient for installation.

[0014] 2) The adjustment assembly allows the lead screw to move forward and backward on the insert block by rotating it. After the first crossbeam is hoisted onto the support, the lead screw can be used to push the first crossbeam to align with the mounting hole on the support, thus completing the rapid installation of the bolts and ensuring construction efficiency and safety.

[0023] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-7 The technical solution of this utility model will be further described in detail below.

[0024] A prefabricated lightweight steel structure factory frame includes columns 1, first crossbeams 2, second crossbeams 4, support columns 3, support mechanisms 7, and third crossbeams 6. The columns 1 are arranged in several groups. The first crossbeams 2 are fixedly connected to the columns 1 at both ends by bolts. One end of the support column 3 is fixedly connected to the first crossbeam 2 by bolts, and the third crossbeam 6 is fixedly connected to the top of the columns 1 by bolts. The support mechanism 7 is fixedly connected to the columns 1 and the first crossbeams 2 by bolts. The second crossbeam 4 is fixedly connected to the top of the support column 3 by bolts, and purlins 5 are fixed between the third crossbeam 6 and the second crossbeam 4 by bolts.

[0025] The support mechanism 7 includes a fixed base 71, a first support arm 72, a second support arm 73, a connecting rod 74, a fixing block 75, and a bidirectional screw 76. One end of the second support arm 73 is hinged to the fixed base 71, and the fixed base 71 is bolted to the first crossbeam 2. One end of the first support arm 72 is hinged to the fixed base 71, and the fixed base 71 is bolted to the column 1. The first support arm 72 has a mounting groove 721, and connecting rods 74 are hinged on both sides of the first support arm 72. One end of the second support arm 73 has a fixedly connected insert arm 731, which is inserted into the mounting block. The insert arm 731 is provided with a through groove 732, and the second support arm 73 is provided with hinged connecting rods 74 on both sides. A pair of fixing blocks 75 are provided on both sides of the insert arm 731, and the ends of the connecting rods 74 are hinged to the ends of the fixing blocks 75. The bidirectional screw 76 is connected to the fixing blocks 75 through a bidirectional thread and passes through the through groove 732. By rotating the bidirectional screw 76, the fixing blocks 75 are moved, and then the first support arm 72 and the second support arm 73 are pushed to slide along the through groove 732 through the connecting rods 74, thereby realizing the adjustment of the overall length of the first support arm 72 and the second support arm 73.

[0026] The column 1 is provided with a pair of support seats 11 arranged symmetrically, which can be bolted to the upper and lower sides of the first crossbeam 2 to improve the support stability; during installation, the bottom support seat is fixed first, then the first crossbeam is installed, and then the top support seat is installed.

[0027] The column 1 is provided with adjustment components 9 on both sides, which can be used to position and adjust the first crossbeam 2 during installation, which facilitates quick installation. The adjustment components 9 include a screw rod 91, a plug 92, and a mounting plate 93. The mounting plate 93 is fixed on the column 1 and is provided with a limiting groove 931. The plug 92 is provided with limiting plates 921 on both sides. The screw rod 91 is threaded to the plug 92. The plug 92 is inserted into the limiting groove 931 and fits into each other. The limiting plates 921 are located on both sides of the mounting plate 93 for limiting.

[0028] When installing the first crossbeam 2 and the support base 11, if the mounting holes on the first crossbeam 2 and the support base 11 are not aligned, it is usually necessary for the construction personnel to manually push them to align. However, due to their excessive weight, hoisting assistance is required, which may cause the first crossbeam 2 to sway significantly, making it difficult to quickly and accurately align with the mounting holes, and even leading to safety accidents. In this case, the insert block 92 is placed in the limiting groove 931, and then the screw rod 91 is rotated to push the first crossbeam 2 on the support base 11, so that the bolt holes on the first crossbeam 2 and the support base 11 are aligned and fixed with bolts.

[0029] Furthermore, the ends of the second crossbeam 4, support column 3, and column 1 are equipped with fixing plates 8 for easy installation and fixing.
