Description

TECHNICAL FIELD

[0001] The utility model relates to construction protection structure technical field, concretely relates to a kind of protection devices for hydraulic creeping formwork platform construction. BACKGROUND

[0002] In bridge engineering, especially in the construction of piers and their superstructure, construction personnel usually complete the reinforcement binding, formwork installation and concrete pouring of the pier on the hydraulic creeping formwork platform. Due to the high height of the hydraulic creeping formwork platform, there are safety risks such as falling during construction.

[0003] To solve the above-mentioned problem of high safety risk during construction on the hydraulic creeping formwork platform, the prior art usually sets up a scaffold protection structure on the construction platform and sets up warning signs on the protection frame structure, which can achieve a certain safety protection effect. However, in actual construction process, on the one hand, even if there are warning signs and safety railings and other warning protection structures, construction personnel in high-intensity working environment are prone to distraction or misjudgment of risk, and may ignore warning protection structures due to noisy working environment or emotional tension of construction personnel, so that the safety warning and safety protection effect are general. On the other hand, although the prior art sets up safety railings and other protection structures to achieve safety protection effect for construction personnel, the protection structure of guardrail type has gaps, and the safety protection effect for construction personnel is limited. Due to the existence of gaps, construction personnel are prone to feel nervous when working in high altitude, which affects construction efficiency, and mechanical tools, materials and other tools during construction process are prone to fall from the gaps of the protection structure and cause safety accidents. Therefore, it is necessary to improve the safety protection structure of the existing hydraulic creeping formwork platform to improve the safety during construction. SUMMARY

[0004] The utility model intends to provide a kind of protection devices for hydraulic creeping formwork platform construction, to solve the problem of low safety of safety protection structure on the hydraulic creeping formwork platform in prior art.

[0005] To solve the above-mentioned problem, the utility model adopts the following technical scheme: a kind of protection devices for hydraulic creeping formwork platform construction, including support bracket and the protection net mechanism connected to the outer side of support bracket, the number of protection net mechanism is several and several protection net mechanisms are arranged along the length direction of support bracket;Protection net mechanism includes protection net body and the inner support piece fixedly connected to one side of protection net body, and the disconnection mechanism is connected between inner support piece and support bracket, and the splicing mechanism is detachably connected between the inner support pieces of adjacent protection net mechanisms.

[0006] The principle of the scheme is: in the application, the support support serves as a support framework, and plays a main force hook part in the safety protection of the construction personnel construction. In addition, although the support support is provided to play the support framework and the protection effect, there is still a gap in the support support which affects the safety protection effect. Therefore, the protective net mechanism is connected outside the support support in the application, which plays a safety protection role in the gap of the support support, and the safety protection is more comprehensive, so that the protective net mechanism and the support support have two layers of protection structure, thereby playing a better safety protection effect.

[0007] In addition, the number of protective net mechanisms in the application is multiple, and the multiple protective net mechanisms are arranged along the length direction of the support support. The number of protective net mechanisms can be determined according to the length of the support support, so that the support support of different lengths can play a good safety protection, and the multiple protective net mechanisms can effectively reduce the weight of a single protective net mechanism when installing the protective net mechanism, so that the installation of the protective net mechanism is more convenient and efficient. At the same time, the protective net mechanism in the application includes a protective net body and an inner support connected to one side of the protective net body. The inner support and the support support are connected through a detachable connection mechanism, which is stable and convenient to disassemble and assemble. The inner supports of adjacent protective net mechanisms are connected through a splicing mechanism, which can ensure the integrity of the protective net body and quickly disassemble and assemble adjacent protective net mechanisms, and is more convenient to use.

[0008] The beneficial effects of the scheme are:

[0009] 1. It can play a more comprehensive safety protection effect: compared with the prior art which only uses scaffolding and other protective structures for safety protection, the safety protection effect is limited. In the application, the two-layer safety protection structure can play a better safety protection effect through the combination of the support support and the protective net mechanism.

[0010] 2. It can effectively reduce the tension of the construction personnel in construction: the protective net mechanism is arranged outside the support support in the application, which can not only play a stable shielding protection effect on the gap position of the support support, but also avoid the construction workers in the high-altitude "suspended" construction state during construction, reduce the psychological pressure of the construction workers in high-altitude operation, and help the construction workers to focus more on the construction operation, thereby improving the efficiency of the construction. At the same time, the protective net mechanism can effectively shield the gap position of the support support, so as to avoid the tools (such as wrenches and other heavy objects) and construction materials falling during construction and causing safety accidents, thereby improving the safety during construction.

[0011] 3. The appearance of the hydraulic creeping formwork platform is more regular: the protective net mechanism in the application is located on the outer side of the support bracket, so that only the net structure of the protective net mechanism can be seen on the outer side of the entire hydraulic creeping formwork platform, the support bracket and other support structures are not exposed in a large area, and the regularity of the outer side of the hydraulic creeping formwork platform is maintained.

[0012] 4. The protective net mechanism is very convenient to disassemble and assemble: the disconnection mechanism arranged in the application can conveniently connect the entire protective net mechanism with the support bracket, and the adjacent protective net mechanisms are detachably connected through the splicing mechanism between the inner support pieces, so that the protective net mechanisms connected with the support bracket are integrated, and a more stable and safe protection effect can be achieved.

[0013] Preferably, as an improvement, the inner support piece includes an inner support square rod fixedly connected to the inner side of the protective net body.

[0015] Preferably, as an improvement, the inner support square rod is hollow inside.

[0016] In the scheme, the inner support square rod is hollow inside, which effectively reduces the weight of the protective net mechanism, and makes the disassembly and assembly of the protective net mechanism more labor-saving and convenient.

[0017] Preferably, as an improvement, the splicing mechanism includes a through hole and a lock hole arranged opposite to each other, the through hole is arranged on the inner support square rod in one of the protective net mechanisms, and the lock hole is arranged on the inner support square rod in the adjacent protective net mechanism.

[0018] In the scheme, the splicing mechanism includes a through hole and a lock hole arranged opposite to each other, in the installation and fixing process, only the bolt in the prior art needs to be passed through the through hole arranged on the inner support square rod, then passed through the lock hole on the inner support square rod of the adjacent protective net mechanism, and then the nut in the prior art is fixed with the bolt, so that the adjacent protective net mechanisms can be fixedly and conveniently connected, the structure is simple and convenient to disassemble and assemble, and the through hole and the lock hole structure can be conveniently arranged on the inner support square rod with a square cross-section. After locking by the bolt, the inner support square rods in the adjacent two protective net mechanisms can be tightly fitted, so that a stable connection relationship is formed between the adjacent protective net mechanisms, and a stable and safe protection effect can be achieved.

[0019] Preferably, as an improvement, a plug is fixedly connected to the inner support square rod in one of the guard net mechanisms, and the plug is inserted into the locking hole of the inner support square rod in the adjacent guard net mechanism, and the length of the plug inserted into the locking hole is less than or equal to the length of the locking hole.

[0020] In this scheme, the plug is fixedly connected to the inner support square rod in one of the guard net mechanisms, and when the adjacent guard net mechanism is connected and fixed, the plug is inserted into the locking hole of the inner support square rod in the adjacent guard net mechanism, and the plug and the locking hole are used to realize the pre-positioning and pre-installation of the adjacent guard net mechanism, which can improve the accuracy and installation efficiency of the connection of the guard net mechanism. In addition, the length of the plug inserted into the locking hole is specially limited to be less than or equal to the length of the locking hole, so as to avoid the end of the plug protruding out of the inner support square rod and affecting the bolt locking and fixing action.

[0021] Preferably, as an improvement, the disconnection mechanism includes two arc-shaped hinged seats arranged opposite to each other, and the arc-shaped hinged seats are rotatably connected with the guard net body, and a screw is detachably connected between the two arc-shaped hinged seats.

[0022] In this scheme, the arc-shaped hinged seats arranged opposite to each other are used to enclose a locking hole for locking and fixing the support bracket, and when the support bracket is placed in the locking hole enclosed by the two arc-shaped hinged seats, the screw between the two arc-shaped hinged seats is locked, so as to stably connect and fix the guard net mechanism and the support bracket, which is convenient and efficient.

At the same time, the arc-shaped hinged seat is rotatably connected with the reinforcing square rod, so that the installation of the arc-shaped hinged seat is more convenient and stable. The locking force of the support bracket on the guard net mechanism can be transmitted to the entire guard net body through the reinforcing square rod, so that the guard net body is more evenly stressed during connection with the support bracket, and is not easily damaged due to excessive local stress during use, and the stability of the entire protective structure is stronger.

[0025] Preferably, as an improvement, the number of disconnection mechanisms in the same guard net mechanism is at least two.

The detachable mechanism comprises two arc-shaped hinge seats 4 arranged opposite to each other, and the two arc-shaped hinge seats 4 are both rotatably connected to the protective net body 2 through a pin shaft. In order to facilitate the installation of the arc-shaped hinge seat 4, a mounting seat 5 is welded on the protective net body 2, and the two arc-shaped hinge seats 4 are rotatably connected to the mounting seat 5.
