Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, and in particular relates to a rod-assembled welcome gate. Background Technology

[0002] A welcoming gate is a prominent gate located at the entrance of a construction site, used to showcase the company's image and project overview. It is typically situated at the entrance to the construction site and is the only way to enter. The welcoming gate not only provides physical isolation and protection but also carries multiple meanings and functions.

[0003] Existing welcome gates mostly adopt traditional cast-in-place and masonry structures, which waste a lot of materials during the construction process, or use materials such as square steel and angle steel for welding and assembly, resulting in problems such as unstable welding quality, difficulty in maintaining the structure during dismantling, transportation difficulties, high costs, and low structural reuse rate. Utility Model Content

[0004] In view of this, and to address the problems of large material consumption, difficult transportation, high construction costs, and low structural reuse rate in the construction of existing welcome gate structures, this utility model proposes a pole-assembled welcome gate, referencing the splicing construction method of high-voltage power towers in the power industry. It designs standard pole components of various lengths according to the overall shape of the welcome gate, and assembles the overall structure of the welcome gate by detachably connecting poles of different lengths. The welcome gate is convenient to install and dismantle, has high turnover efficiency, is easy to store and transport, and is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rod-assembled welcome gate, comprising mutually perpendicular welcome gate beams and welcome gate columns, the welcome gate beams and two welcome gate columns forming a gantry shape, the welcome gate beams comprising multiple beams, multiple support rods and multiple diagonal braces, the multiple beams being arranged in parallel, the multiple support rods being detachably connected perpendicularly to the beams, and the multiple diagonal braces being detachably connected to the beams at a 45-degree angle;

[0006] The welcoming gate pillar includes multiple pillars, multiple support rods, and multiple diagonal braces. The multiple pillars are arranged in parallel, the multiple support rods are detachably connected to the pillars perpendicularly, and the multiple diagonal braces are detachably connected to the pillars at a 45-degree angle. The bottom of the welcoming gate pillar is connected to the external foundation fixing steel plate, and the support rod at the top of the welcoming gate pillar is detachably connected to the beam at the bottom of the welcoming gate beam.

[0007] Furthermore, the crossbeam consists of four beams arranged in a quadrangular prism shape, and the column includes two groups of eight beams, with four beams in each group arranged in a quadrangular prism shape. The multiple support rods and multiple diagonal braces are all located on the side surface of the quadrangular prism.

[0008] Furthermore, the detachable connection is achieved by using bolts passing through through holes and engaging with nuts.

[0009] Furthermore, the crossbeams, columns, and the support rods at the top of the welcoming gate columns are all made of angle steel.

[0010] Furthermore, the support rod has bolt holes at both ends, and the two right-angled sides of the crossbeam and the two right-angled sides of the column are each provided with multiple bolt holes at equal intervals. After the support rod is fixed to the crossbeam or column through the bolt holes, the side surface of the quadrangular prism is divided into multiple squares.

[0011] Furthermore, the diagonal brace has bolt holes at both ends, and the diagonal brace is located on the diagonal of the square. The crossbeam and column are also provided with bolt holes. Adjacent diagonal braces are staggered, and the diagonal brace on the side of a single column is generally wavy and zigzag-shaped.

[0012] Furthermore, the diagonal bracing is provided on a pair of opposite column sides of each quadrangular prism.

[0013] Furthermore, the bottom edge of the crossbeam at the bottom of the welcoming door beam and the top edge of the support rod at the top of the welcoming door pillar directly below it are both provided with strip holes for assembly and fixing.

[0014] Furthermore, the crossbeam is a left-right splicing structure, comprising a left rod, a right rod, and a pair of five-hole connecting plates. The splicing joint of the left and right rods is provided with semi-circular bolt holes one, two, and three in sequence from the outside to the inside. After the left and right rods are aligned, the splicing joint forms a five-hole structure. The pair of five-hole connecting plates clamp the five-hole structure from the inside and outside and align it with it. The bolt and nut pass through bolt hole three and engage to connect and fix the left rod, right rod, and five-hole connecting plates.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0030] I. Detailed Implementation Method 1, see [link / reference] Figure 1-9This embodiment describes a rod-assembled welcome gate, which includes mutually perpendicular welcome gate beams and welcome gate columns. The welcome gate beams and two welcome gate columns form a gantry shape. The welcome gate beams include multiple beam rods 1, multiple support rods 3, and multiple diagonal braces 4. The multiple beam rods 1 are arranged in parallel. The multiple support rods 3 are detachably connected to the beam rods 1 perpendicularly. The multiple diagonal braces 4 are detachably connected to the beam rods 1 at a 45-degree angle.

[0031] The welcoming gate pillars include multiple pillar rods 2, multiple support rods 3, and multiple diagonal braces 4. The multiple pillar rods 2 are arranged in parallel, the multiple support rods 3 are detachably connected to the pillar rods 2 perpendicularly, and the multiple diagonal braces 4 are detachably connected to the pillar rods 2 at a 45-degree angle. The bottom end of the welcoming gate pillars is connected to the external foundation fixing steel plate, and the support rods 3 at the top of the welcoming gate pillars are detachably connected to the crossbeam rods 1 at the bottom end of the welcoming gate crossbeam.

[0032] The external foundation fixing steel plate is connected and fixed to the anchor bolts of the foundation poured on site. The anchor bolts are high-strength bolts with a length of 800mm and a thread length of not less than 150mm. The foundation concrete is C30. After the foundation is poured, the exposed length of the anchor bolt threads is not less than 120mm. The bottom end of the welcoming gate column is welded and fixed to the external foundation fixing steel plate, completing the foundation positioning and fixing of the welcoming gate.

[0033] The crossbeam 1 consists of 4 beams arranged in a quadrangular prism shape. The column 2 consists of two groups of 8 beams, with 4 beams in each group arranged in a quadrangular prism shape. The multiple support rods 3 and multiple diagonal braces 4 are all located on the side of the quadrangular prism.

[0034] The detachable connection is achieved by using bolts passing through through holes and engaging with nuts; high-strength bolts are selected for the connection.

[0035] The crossbeam 1, column 2, and support rod 3 at the top of the welcoming gate column are all made of angle steel. Since both right-angled sides of these parts need to be assembled, an angle steel structure is used. The crossbeam 1 and column 2 need to be assembled with the support rod 3 and multiple diagonal braces 4 in two directions. The support rod 3 at the top of the welcoming gate column needs to be assembled with the bottom surface of the column 2 and the bottom surface of the crossbeam 1 at the bottom of the welcoming gate crossbeam. Except for the above-mentioned parts, all other parts can use conventional sheet metal structures or uniformly use galvanized equal-leg angle steel structures. Using angle steel structures for all parts facilitates transportation. Galvanized equal-leg angle steel with a specification of 60mm × 60mm is selected.

[0036] The support rod 3 has bolt holes 5 at both ends. The two right-angled sides of the crossbeam 1 and the two right-angled sides of the column 2 are also provided with multiple bolt holes 5 at equal intervals. After the support rod 3 is fixed to the crossbeam 1 or the column 2 through the bolt holes 5, the side surface of the quadrangular prism is divided into multiple squares. The crossbeam 1 and the column 2 are angle steel structures, each arranged in a square at the four corners. Multiple bolt holes 5 are provided at equal intervals on both sides of the crossbeam 1 and the column 2 for assembly and fixation with the support rod 3, forming the frame structure of the welcoming gate crossbeam and the frame structure of the welcoming gate column.

[0037] The diagonal brace 4 has bolt holes 6 at both ends and is located on the diagonal of the square. Corresponding bolt holes 6 are also provided on the crossbeam 1 and column 2. Adjacent diagonal braces 4 are staggered, and the diagonal brace 4 on the side of a single column has a wavy, zigzag shape. Considering the large size of the welcoming gate and its self-weight, diagonal braces 4 are added to the frame structure of the welcoming gate's crossbeam and column to form triangular stable units, optimizing the mechanical transmission structure and improving the overall structural support strength. The wavy, zigzag-shaped diagonal braces 4 form continuous triangular stable units, and the wavy, zigzag-shaped load transmission path makes the load distribution more uniform.

[0038] The diagonal bracing 4 is disposed on a pair of opposite column sides of each quadrangular prism. In this embodiment, considering practical application and material conservation, it is only disposed on one diagonal of a pair of opposite square surfaces of each quadrangular prism to meet the load-bearing requirements. The diagonal bracing 4 can be installed according to the load-bearing requirements of the specific structure, and can be selectively installed on the intersecting diagonal of the square surfaces of all quadrangular prisms.

[0039] The bottom edge of the crossbeam 1 at the bottom of the welcoming gate beam and the top edge of the support rod 3 at the top of the welcoming gate pillar directly below it are both provided with slotted holes 7 for assembly and fixing. Bolts and nuts are used through the slotted holes 7 to fix the welcoming gate beam and the welcoming gate pillar into an integrated structure, forming the welcoming gate. The slotted holes 7 have an installation allowance to accommodate installation errors in other areas during assembly.

[0040] The crossbeam is a left-right splicing structure, comprising a left rod, a right rod, and a pair of five-hole connecting plates 8. At the splicing point of the left and right rods, semi-circular bolt holes 1-9, 2-6, and 3-10 are sequentially arranged from the outside in. After the left and right rods are aligned, a five-hole structure is formed at the splicing point. The pair of five-hole connecting plates 8 clamp the five-hole structure from both the inside and outside, aligning it with the structure. Bolts and nuts pass through bolt hole 3-10 and engage to connect and fix the left rod, right rod, and five-hole connecting plates 8. In practice, angle steel materials rarely meet the length requirements of the crossbeam 1. Therefore, the design uses two angle steel materials to form the crossbeam 1. Bolt holes 3-10 on both sides of the five-hole connecting plate 8 are used to fix the left and right rods, while the three holes in the middle are used to assemble the support rod 3 and the diagonal brace 4.

[0041] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
