DETAILED DESCRIPTION

[0026] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0027] Embodiment 1: The utility model is to solve one of the above-mentioned technical problems, and the technical solution adopted is: a balcony ground-connected guardrail, comprising two oppositely arranged wall-connected units, the two wall-connected units are fixed on the inner wall 1 of the window at corresponding positions, a guardrail component 2 is arranged between the two wall-connected units, the upper parts of both ends of the guardrail component 2 are respectively detachably fixed on the upper parts of the corresponding wall-connected units, a ground-connected unit is arranged on the ground 9 below the guardrail component 2, the two ends of the ground-connected unit are respectively fixed on the lower parts of the wall-connected units at corresponding positions, a plurality of threaded columns 4 are cooperated and installed above the wall-connected unit, the lower ends of each threaded column 4 are screwed and fastened to the top of the ground-connected unit, and the tops of each threaded column 4 are respectively inserted and fitted at the corresponding positions of the lower ends of the guardrail component 2. The entire balcony ground guardrail is positioned as a whole by relying on the expansion bolts 7 of the wall units on both sides. The overall positioning of the entire balcony guardrail with a shorter length can be completed by supporting multiple wall fixing points. After the wall units on both sides are installed as an integral fixed structure, positioning support can be provided for the guardrail component 2. The bottom support of each stud column can ensure the stability of the positioning of each guardrail vertical steel pipe 203 at the bottom of the guardrail component 2, thereby ensuring the firm positioning effect of both sides and the bottom of the entire structure.

[0028] In any of the above schemes, it is preferred that the wall connecting unit includes a vertically arranged C-shaped steel frame 5, the opening cavity 6 of the C-shaped steel frame 5 is arranged toward the guardrail component 2, the upper and lower ends of the opening cavity 6 are both through-set, the back of the C-shaped steel frame 5 abuts against the corresponding window inner wall 1 and is fixed by a plurality of expansion bolts 7, the upper part of the C-shaped steel frame 5 is detachably fixedly connected to the upper end of the corresponding side of the guardrail component 2, and the lower part of the C-shaped steel frame 5 is detachably fixedly connected to the corresponding end of the ground connecting unit.

[0029] The C-shaped steel frame 5 of the wall-connected unit serves as the main positioning structure. It is fixed to the wall by multiple expansion bolts 7 arranged from top to bottom to ensure the strength of the positioning of the entire structure. After the expansion bolts 7 are installed, they can be used as positioning parts for the entire guardrail component 2. In addition, since the guardrail component 2 and the C-shaped steel frame 5 are connected in a detachable manner, it can be ensured that the guardrail component 2 can be quickly disassembled and reinstalled after the window glass is damaged, which facilitates glass repair.

[0030] In any of the above schemes, it is preferred that the guardrail component 2 includes a horizontally arranged guardrail cross steel pipe 201, both ends of which are respectively inserted into the opening cavity 6 on the corresponding side and fastened and fixed by upper bolts 202, and a plurality of vertically arranged guardrail vertical steel pipes 203 are evenly spaced and fixed at the bottom of the guardrail cross steel pipe 201 along its length direction, and the lower end of each guardrail vertical steel pipe 203 is movably connected to the upper outer wall of the corresponding threaded column 4 therebelow.

[0031] The guardrail component 2 is made as a whole in a fully welded manner, relying on the guardrail horizontal steel pipe 201 as a horizontal connecting component. The guardrail vertical steel pipes 203 welded at the bottom of the guardrail horizontal steel pipe 201 can play a role in bottom support and fixation. The bottom of each guardrail vertical steel pipe 203 is sleeved on the upper outer wall of the corresponding threaded column 4 to ensure the stability of the bottom support of the entire structure.

[0032] In any of the above schemes, it is preferred that the ground connecting unit includes a horizontally arranged ground connecting steel seat 8, the bottom of the ground connecting steel seat 8 abuts against the top of the ground 9 at the window sill position, and both ends of the ground connecting steel seat 8 are folded upward to form a plug-in seat 801, and each of the plug-in seats 801 is respectively inserted into the opening cavity 6 at the corresponding position and fastened and fixed by the lower bolt 10, and a plurality of welded spiral tubes 11 are evenly spaced along the length direction on the top of the ground connecting steel seat 8, and the inner wall of the inner cavity 204 of each of the welded spiral tubes 11 is provided with an internal thread for matching with the external thread on the lower outer wall of the threaded column 4.

[0033] The ground-connecting unit is directly connected to the window sill above the ground 9, and there is no need to drill holes on the ground 9 or the window sill. When fixing the ground-connecting steel seat 8 of the ground-connecting unit, it is only necessary to rely on the plug-in sockets 801 at both ends to complete the positioning. The entire installation construction is relatively simple and quick. In addition, since the bottom of each threaded column 4 is screwed and fastened to the internal thread of the corresponding welding spiral tube 11 by threaded screwing and the bottom is abutted against the top of the ground-connecting steel seat 8, it can both fix and prevent arbitrary movement.

[0034] Embodiment 2: Compared with Embodiment 1, this embodiment further includes the following technical features:

[0035] In any of the above schemes, it is preferred that the upper portion of each of the threaded columns 4 is movably inserted into the inner cavity 204 of the corresponding guardrail vertical steel pipe 203 above it, and a vertical spring 205 is respectively installed in the inner cavity 204 of the guardrail vertical steel pipe 203 above each of the threaded columns 4, and the bottom of each of the vertical springs 205 is respectively abutted against the top of the threaded column 4, and the top of each of the vertical springs 205 is respectively abutted against the bottom of the guardrail horizontal steel pipe 201.

[0036] After the top of each threaded column 4 is screwed into the inside of the corresponding welded spiral tube 11, it can be tightened by the corresponding vertical spring 205, thereby achieving the effect of preventing it from falling off. In addition, during the installation process of the threaded column 4, it is necessary to first push the threaded column 4 upward with force so that its lower end is higher than the top of the corresponding welded spiral tube 11 (that is, before installing the guardrail component 2, it is necessary to pre-match and insert each vertical spring 205 and the threaded column 4 into the tube cavity of the corresponding guardrail vertical steel pipe 203). After the bolting and positioning of the two ends of the guardrail component 2 are completed, the threaded column 4 is screwed downward into the inside of the welded spiral tube 11 by screwing the corresponding threaded column 4 one by one. The corresponding vertical spring 205 always maintains downward contact with the threaded column 4, thereby achieving the purpose of preventing it from falling off and preventing children from disassembling. When selecting, it is necessary to reasonably control the elastic coefficient of the current vertical spring 205 to effectively ensure its downward tightening force.

[0037] In any of the above solutions, it is preferred that each of the upper bolts 202 and each of the lower bolts 10 are anti-theft bolts.

[0038] Anti-theft bolts can better prevent random disassembly in normal times. Disassembly must be completed with special disassembly tools, which can effectively improve the safety of their installation. At the same time, professional tools can be used to quickly disassemble and reinstall when disassembly is required.

[0039] In any of the above solutions, preferably, an arc-shaped rounded surface 12 is provided at the contact portion between each of the plug sockets 801 and the ground-connecting steel seat 8 .

[0040] In any of the above solutions, preferably, an upper rounded surface 13 is provided at the top frame of each of the C-shaped steel frames 5 .

[0041] The design of the arc-shaped rounded surface 12 and the upper rounded surface 13 can play a protective role and reduce the probability of scratching the user.

[0042] In any of the above solutions, preferably, a chamfered surface 3 is provided at the lower end surface of each of the threaded columns 4 .

[0043] Each chamfered surface 3 on the lower end surface of the threaded column 4 mainly plays a guiding role when screwing downward.

[0044] Specific working principle: During installation, the prefabricated components of the entire guardrail are transported to the balcony location to be installed in advance, and the entire balcony ground guardrail can be positioned as a whole by relying on the expansion bolts 7 of the wall units on both sides.

[0045] After installation, the overall positioning of the entire balcony guardrail with a shorter length can be completed through the support of multiple wall-connecting fixing points. After the wall-connecting units on both sides are installed as an integral fixed structure, positioning support can be provided for the guardrail component 2.

[0046] The bottom support of each stud column can ensure the stability of the positioning of each guardrail steel pipe 203 at the bottom of the guardrail component 2, thereby ensuring the firm positioning of the sides and bottom of the entire structure. Each guardrail steel pipe 203 welded at the bottom of the guardrail horizontal steel pipe 201 can play the role of bottom support and fixation, and the bottom of each guardrail steel pipe 203 is sleeved on the upper outer wall of the corresponding threaded column 4 to ensure the stability of the bottom support of the entire structure. In addition, it can be seen that the ground connection unit is directly connected to the window sill above the ground 9, and there is no need to drill holes on the ground 9 or the window sill. When fixing the ground connection steel base 8 of the ground connection unit, it only needs to rely on the plug-in sockets 801 at both ends to complete the positioning. The entire installation construction is relatively simple and quick.

[0047] From the above, it can be seen that the balcony guardrail relies on the wall-connecting units arranged on both sides to complete the fixing and positioning of the entire guardrail structure, and can be suitable for the protective installation of the balcony part with double windows of shorter length. During the installation process, each wall-connecting unit is completely fixed and positioned only by the positioning of multiple expansion bolts 7 arranged thereon. The subsequent guardrail component 2 relies on the positioning of the wall-connecting unit to avoid the installation of drilling holes in the ground 9, reducing the difficulty and number of construction drilling holes; the entire guardrail component 2 is composed of a fully welded structure, and its two ends are fastened and fixed by upper bolts 202, and the lower part is abutted and supported by various vertical springs 205. At the same time, it relies on various threaded columns 4 and the bottom welded screw tubes 11 to achieve threaded fastening cooperation, so as to achieve stable and rapid installation of the entire balcony guardrail structure; the two ends of the ground-connecting unit are directly fixed and bolted to the corresponding wall-connecting unit to ensure its overall firmness, avoid the ground-connecting drilling operation, and effectively reduce the difficulty of guardrail installation.

[0048] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model. For technicians in this technical field, any replacement improvements or changes made to the implementation methods of the utility model fall within the protection scope of the utility model.

[0049] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
