Description

Technical Field

[0001] This utility model relates to the technical field of construction protection devices, specifically a protective support for building engineering. Background Technology

[0002] Construction engineering refers to the planning, surveying, design, construction, and completion of various technical tasks for the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, protective supports are needed to enclose the building or the scope of the project to prevent unauthorized personnel from entering the construction site and to prevent construction workers from accidentally falling from heights.

[0003] In existing technologies, protective supports typically consist of at least two metal rods, which are fixed to the ground or inserted into the ground using expansion bolts. A metal mesh is installed between the metal rods, with metal plates on both sides and the inner side of the mesh. These metal plates are then connected by bolts. Because the metal mesh and metal rods are bolted together, installation requires two to three people: two to lift the mesh to ensure the bolt holes on the metal plates are aligned, and another to insert the bolts and tighten the nuts. This installation process is time-consuming. Furthermore, in actual use, the nuts are prone to coming loose due to vibration or other reasons, causing the bolts to fail. In this case, at least one corner of the metal mesh will separate from the metal rod, losing its protective effect. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a protective support for building engineering.

[0005] The technical solution of this utility model is:

[0006] A protective support frame for construction projects, comprising:

[0007] The base has a column on top, the column includes a vertical tube, the tops of two adjacent vertical tubes are connected by a clamping plate, and a guardrail is provided between the columns. The guardrail includes an isolation component, which is connected to the column by a clamping component.

[0008] Preferably, the top outer side of the riser is provided with a first slot, and the card plate is inserted into the first slot and simultaneously engaged with the two columns.

[0009] Preferably, the top of the riser is provided with a sealing cap, which is inserted into the riser and engaged with the clamping plate, and the length of the riser is greater than the depth of the first clamping groove.

[0010] Preferably, the riser is symmetrically provided with fixing plates on the side near the guardrail, and the fixing plate has a positioning groove in the middle of its top surface facing downwards.

[0011] Preferably, the snap-fit ​​assembly includes connecting ears, which are fixedly installed on both sides of the isolation assembly. The connecting ears are provided with first screws on the front and rear sides. The connecting ears are inserted between the fixing plates and snap-fitted with the positioning groove through the first screws.

[0012] Preferably, the first screw is wrapped with a protective sleeve, and the protective sleeve has an annular groove in the middle. The protective sleeve is inserted into the first slot through the annular groove, and the outer diameter of the protective sleeve is larger than the inner diameter of the first slot.

[0013] Preferably, the first screw is threaded with locking nuts at both ends, and the end face of the locking nut abuts against the protective sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention utilizes the cooperation of a clamping plate and a first clamping slot to fix the tops of two adjacent columns, making installation more convenient than with bolts. The engagement of the first screw and the positioning slot provides initial fixation of the guardrail, eliminating the need for additional manual fixation during installation and reducing installation difficulty. The engagement of the protective sleeve and the fixing plate enhances the connection strength between the first screw and the positioning slot, while the friction between the locking nut and the end face of the protective sleeve prevents the locking nut from falling off. The fixing plate prevents the connecting ears from moving back and forth, thus avoiding a decrease in protective capability due to the locking nut falling off. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] A protective support frame for construction projects, comprising:

[0030] The base 1 has a column 2 on top of it. The column 2 includes a riser 21. The tops of two adjacent risers 21 are connected by a clamping plate 25. A guardrail 3 is provided between the columns 2. The guardrail 3 includes an isolation component. The isolation component is connected to the column 2 by a clamping component.

[0031] The base 1 includes a support plate 11, and a first connecting rod 12 is welded to the top surface of the support plate 11. The first connecting rod 12 is inserted into the riser 21 from the bottom and fixed to the riser 21 by bolts.

[0032] The top surface of the base 1 has several vertically penetrating fixing holes 13, which are used to insert expansion bolts or rivets to fix it to the ground.

[0033] The top outer side of the riser 21 is provided with a first slot 24, and the card plate 25 is inserted into the first slot 24 and simultaneously engaged with the two columns 2.

[0034] The clamping plate 25 can fix the top of the riser 21, so that two adjacent risers 21 can form a whole.

[0035] The top of the riser 21 is provided with a sealing cap 26, which is inserted into the riser 21 and engaged with the clamping plate 25. The length of the riser 21 is greater than the depth of the first clamping groove 24.

[0036] The sealing cover 26 is interference-fitted with the riser 21. The sealing cover 26 is used to close the top opening of the riser 21 and the first slot 24. At the same time, the sealing cover 26 can press the card plate 25 from above to prevent the card plate 25 from falling off.

[0037] The riser 21 is symmetrically provided with fixing plates 22 on the side near the guardrail 3, and the top surface of the fixing plate 22 is provided with a positioning groove 23 facing downward.

[0038] The fixing plates 22 are arranged in pairs, and each pair of fixing plates 22 is welded to the riser 21. The positioning groove 23 is U-shaped.

[0039] The isolation component includes a fixed frame 31, and an isolation mesh 32 is welded inside the fixed frame 31.

[0040] Isolation components are used to prevent people from passing through.

[0041] The snap-fit ​​assembly includes a connecting ear 33, which is fixedly installed on both sides of the isolation assembly. The connecting ear 33 has a first screw 34 on its front and rear sides. The connecting ear 33 is inserted between the fixing piece 22 and snap-fitted with the positioning groove 23 through the first screw 34.

[0042] The connecting lugs 33 are welded to the outer sides of the fixing frame 31 on both sides. The space between the two fixing plates 22 is greater than the width of the connecting lugs 33, and the outer diameter of the first screw 34 is smaller than the positioning groove 23. The fixing plates 22 can prevent the connecting lugs 33 from moving back and forth, and the positioning groove 23 can prevent the first screw 34 from moving downward.

[0043] The first screw 34 is wrapped with a protective sleeve 35. The protective sleeve 35 has an annular groove 36 in the middle. The protective sleeve 35 is inserted into the first slot 24 through the annular groove 36. The outer diameter of the protective sleeve 35 is larger than the inner diameter of the first slot 24.

[0044] The protective sleeve 35 can be made of nylon or rubber. The protective sleeve 35 can prevent the threads of the first screw 34 from directly contacting the positioning groove 23, thus protecting the first screw 34. At the same time, it increases the friction between the first screw 34 and the positioning groove 23, thereby improving the snap-fit ​​strength.

[0045] The first screw 34 has locking nuts 37 threaded at both ends, and the end face of the locking nut 37 abuts against the protective sleeve 35.

[0046] After the locking nut 37 is tightened, it can work with the fixing plate 22 to clamp the protective sleeve 35, thereby fixing the first screw 34. At the same time, the protective sleeve 35 can increase the friction on the end face of the locking nut 37 and reduce the probability of the locking nut 37 falling off.

[0047] In this embodiment, when the operator uses this equipment, first use expansion bolts to fix the support plate 11 to the ground, then fix the riser 21 to the first connecting rod 12, then use the clamping plate 25 to fix the top of the two adjacent risers 21, and then insert the sealing cover 26.

[0048] Put the protective sleeve 35 onto the first screw 34, then insert the connecting lug 33 between the fixing pieces 22. At the same time, the first screw 34 should be engaged in the positioning groove 23, and the fixing piece 22 should be inserted into the annular groove 36.

[0049] Finally, tighten the lock nut 37 to complete the installation.

[0050] Example 2:

[0051] Please see Figure 5 Unlike in Embodiment 1, the two columns 2 can be installed vertically by means of the extension 4, thereby increasing the protective height of the device.

[0052] The extension member 4 includes an extension rod 41, and a gasket 42 is welded to the middle of the extension rod 41.

[0053] Insert the lower end of the extension rod 41 into the top of the riser 21 until the bottom surface of the gasket 42 abuts against the top surface of the lower riser 21. Then, place the bottom of the second riser 21 onto the top surface of the extension rod 41 until the bottom surface of the upper riser 21 abuts against the top surface of the gasket 42. Finally, reinforce with bolts.

[0054] Finally, install guardrail 3 between risers 21. Installation complete.

[0055] Multiple columns 2 can be connected by using the extension piece 4.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
