Description

Technical Field

[0001] The utility model relates to the technical field of cantilever I-beam external frame construction, in particular to a fixing device for erecting a steel pipe frame on an I-beam, which is suitable for installation on various types of I-10 to I-40 steel. Background Art

[0002] During the construction of cantilevered external frames and bridge support protection, Φ48 steel pipes are usually required to build external frames or support protection. When setting up protective railings, the cantilever I-beam is usually installed first, and then a short steel bar head is welded at the end of the cantilever and inserted into the hollow of the vertical pole to prevent displacement caused by vibration during the erection of the external frame, and the support point falls off, causing safety accidents. In the construction of bridge support protection, the vertical poles are generally welded with profiles. Finally, horizontal protective railings, skirting boards, etc. are set up.

[0003] However, in this case, the cantilever I-beam is generally rented from outside and transported to the site for use. The specific steps for the cantilever external frame installation are as follows: After the I-beam material arrives at the site, it is first inspected for defects, and qualified products enter the paint coating area. After the coating is completed, it is hoisted to the top plate of the first floor of the building structure. The electric welder welds Φ16~18 HRB400 short steel bars (6cm long) limiting bars at the end of the I-beam. After welding, the cantilever I-beam is installed at the designed position. Finally, the scaffolding workers cooperate with each other to install the vertical poles and large and small cross bars at the short steel bar position. Since the top of the bracket generally uses I-beams as distribution beams, the protective steel pipe generally uses spot welding to weld the vertical poles to the I-beams, and then install the upper, middle and lower cross bars.

[0004] In view of the above situation, no matter which construction field, temporary electricity consumption and fire safety hazards are increased, which increases the safety risk for the project as a whole, and is inconvenient for installation and dismantling (when the I-beam material is returned, the short steel bars need to be cut); for the cantilevered external frame, the consumption of steel bar materials is additionally increased, which is not conducive to resource conservation and is labor-intensive and time-consuming. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides a fixing device for erecting a steel pipe frame on an I-beam, comprising: a self-anchoring member, which includes a pressure plate sleeved on the upper wing plate of the cantilever I-beam and a sleeve bolt fixed on the top of the pressure plate; an extrusion rod adjuster, which is installed above the self-anchoring member and rotatably connected to the sleeve bolt; a threaded extrusion rod, which passes through the extrusion rod adjuster and the sleeve bolt and abuts against the top surface of the upper wing plate of the cantilever I-beam, the threaded extrusion rod is threadedly connected to the extrusion rod adjuster, and the extrusion rod adjuster is rotated to move the threaded extrusion rod downward to drive the pressure plate to self-anchor on the cantilever I-beam.

[0007] Preferably, the pressure plate includes a Y-shaped clamp located on both sides of the web of the cantilever I-beam and on the lower side of the upper wing plate of the cantilever I-beam, and a U-shaped support plate integrally formed with the Y-shaped clamp and surrounding the Y-shaped clamp and the upper wing plate of the cantilever I-beam; the sleeve bolt is fixed to the top of the U-shaped support plate, and the upper support plate of the U-shaped support plate is reserved with a hole coaxially arranged with the sleeve bolt and for the threaded extrusion rod to pass through.

[0008] Furthermore, the extrusion rod adjuster includes an adjuster inner sleeve and a limit ring which are distributed up and down and coaxially arranged, and the interior of the adjuster inner sleeve has a threaded hole which is threadedly connected to the threaded extrusion rod; the limit ring is rotatably connected to the interior of the sleeve bolt, and the interior of the limit ring has a through hole for the threaded extrusion rod to pass through.

[0009] Preferably, an adjustment handle extending radially outward is provided at the connection between the inner sleeve of the regulator and the limiting ring.

[0010] Furthermore, a pressure plate for applying pressure to the top surface of the upper wing plate of the cantilever I-beam is fixed at the bottom of the threaded extrusion rod, and the top surface of the upper wing plate of the cantilever I-beam is provided with two guide columns arranged vertically upward, and the two guide columns are symmetrically arranged with respect to the threaded extrusion rod; positioning holes for the two guide columns to pass through are formed on the pressure plate.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following Figure 1 to Figure 7 The fixing device for erecting a steel pipe frame on an I-beam of the utility model is described in detail.

[0027] The fixing device for erecting a steel pipe frame on an I-beam of the utility model comprises a self-anchor 1, a threaded extrusion rod 3 and an extrusion rod adjuster 4 assembled together. The threaded extrusion rod 3 and the extrusion rod adjuster 4 are used in conjunction with each other to anchor the self-anchor 1 on the cantilever I-beam. The self-anchor 1 comprises a pressure plate 1a sleeved on the upper wing plate of the cantilever I-beam and a sleeve bolt 1b fixed on the top of the pressure plate 1a. The extrusion rod adjuster 4 is installed above the self-anchor 1 and is rotatably connected with the sleeve bolt 1b. The threaded extrusion rod 3 passes through the extrusion rod adjuster 4 and the sleeve bolt 1b and abuts against the top surface of the upper wing plate of the cantilever I-beam. The threaded extrusion rod 3 is threadedly connected with the extrusion rod adjuster 4. The extrusion rod adjuster 4 is rotated to move the threaded extrusion rod 3 downward to drive the pressure plate 1a to self-anchor on the cantilever I-beam.

[0028] like Figure 2 and Figure 7 As shown, the pressure plate 1a includes a Y-shaped clamp 1a1 located on both sides of the web of the cantilever I-beam and the lower side of the upper wing of the cantilever I-beam, and a U-shaped support plate 1a2 integrally formed with the Y-shaped clamp 1a1 and surrounding the Y-shaped clamp 1a1 and the upper wing of the cantilever I-beam. The sleeve bolt 1b is welded to the top of the U-shaped support plate 1a2, and the upper support plate of the U-shaped support plate 1a2 is reserved with a hole coaxially arranged with the sleeve bolt 1b and for the threaded extrusion rod 3 to pass through. The Y-shaped clamp 1a1 and the U-shaped support plate 1a2 are integrally pressed, and the sleeve bolt 1b and the U-shaped support plate 1a2 are seamlessly welded.

[0029] In addition, a pressing plate 2 for applying pressure to the top surface of the upper wing plate of the cantilever I-beam is fixed at the bottom of the threaded extrusion rod 3 of the utility model, and the threaded extrusion rod 3 and the pressing plate 2 are seamlessly welded to form a whole. The top surface of the upper wing plate of the cantilever I-beam is provided with two guide pillars (marked in the figure) arranged vertically upward, and the two guide pillars are symmetrically arranged about the threaded extrusion rod 3. Among them, a positioning hole for the two guide pillars to pass through is formed on the pressing plate 2. The setting of the guide pillars can prevent the threaded extrusion rod 3 from rotating with the extrusion rod adjuster 4, which is more conducive to realizing the conversion of the rotation of the extrusion rod adjuster 4 into the up and down movement of the threaded extrusion rod 3.

[0030] like Figure 4 and Figure 5 As shown, the extrusion rod regulator 4 includes an regulator inner sleeve 4a and a stop ring 4c which are coaxially arranged and distributed up and down. The inner sleeve 4a of the regulator has a threaded hole threadedly connected to the threaded extrusion rod 3. The stop ring 4c is rotatably connected to the inside of the sleeve bolt 1b. The inner stop ring 4c has a through hole for the threaded extrusion rod 3 to pass through. The sleeve bolt 1b is used in conjunction with the stop ring 4c. Then, the movement of the threaded extrusion rod 3 and the extrusion plate 2 mainly depends on the rotation of the adjustment handle 4b to drive the threaded extrusion rod 3 to move up and down, thereby locking the component of the utility model on the cantilever I-beam.

[0031] Specifically, the outer circumference of the limit ring 4c has an annular groove concave inward, and the inner circumference of the sleeve bolt 1b has an annular convex strip that matches the groove and convex outward. The rotational connection between the limit ring 4c and the sleeve bolt 1b is achieved through the cooperation of the annular convex strip and the annular groove. The sleeve bolt 1b and the limit ring 4c are used in a fixed manner. The sleeve bolt 1b and the limit ring 4c can be integrally forged and formed by a mechanical parts processing factory. They mainly ensure that the threaded extrusion rod 3 prevents the rod from loosening after the rod is moved up and down and positions, and bears the pulling force of the rod moving upward. The connection between the regulator inner sleeve 4a and the limit ring 4c is provided with an adjustment handle 4b extending radially outward. The adjustment handle 4b is welded to the regulator inner sleeve 4a and the limit ring 4c as a whole, and the extrusion rod regulator 4 is rotated by the adjustment handle 4b.

[0032] like Figure 7 As shown, the inner sleeve 4a of the regulator is covered with a protective upright pole 6. After the assembly of the utility model is completed, the protective upright pole 6 of the outer frame upright pole or the bridge support is inserted into the inner sleeve 4a of the regulator, and then the upper, middle and lower cross bars are installed.

[0033] In the utility model, the self-anchor 1 is provided with a Y-shaped opening that opens downwards, and the Y-shaped opening is used to pass through the cross section of the cantilever I-beam and cooperate with the threaded extrusion rod 3. As the threaded extrusion rod 3 drives the pressing plate 2 to move downward, the Y-shaped clamping plate 1a1 slowly approaches the lower side of the upper wing plate of the cantilever I-beam, and with the rotation of the extrusion rod adjuster 4, the upper inclined plate clamping piece and the vertical plate clamping piece of the Y-shaped clamping plate 1a1 are gradually tightened, and finally firmly fit with the lower side surface and web of the upper wing plate of the cantilever I-beam, and self-anchored on the cantilever I-beam, no twisting occurs in the four directions of the front, back, left, and right of the anchor point, and the reverse operation can be performed when disassembling.

[0034] It can be seen that after the self-anchored structural member of the utility model is finalized and manufactured, it is installed on the cantilever I-beam, which is easy to operate, quick and recyclable. Compared with the welding method in the prior art, it saves steel bar materials, does not use electric welding, improves the versatility of the connection with the I-beam, and reduces the number of processes and operation time.

[0035] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
