Description

Technical Field

[0001] The utility model belongs to the technical field of protective devices, and particularly relates to a safety protection device for building construction openings. Background Technique

[0002] In building construction, floor openings are common construction features, which may be reserved for installing pipelines, cables, ventilation systems or other structural elements. Usually, the smaller ones are called holes and the larger ones are called openings. The specific regulations are as follows: on horizontal planes such as floors, roofs, and platform surfaces, those with short side dimensions less than 25 cm, and on vertical planes such as walls, those with a height less than 75 cm are called holes; on horizontal planes, when the short side dimension is equal to or greater than 25 cm, on vertical planes, when the height is equal to or greater than 75 cm and the width is greater than 45 cm, it is called an opening.

[0003] During the building construction process, the treatment of floor openings is crucial. To ensure construction safety and site order, special fences are usually used to tightly enclose them, so as to achieve the physical isolation of the opening area from the external environment. The main purpose of setting up such fences is to prevent people from straying in or materials from falling, thus effectively avoiding potential safety hazards. However, it is worth noting that although these fences strive to be tight in design and installation, in many cases, their enclosing structures may still retain a certain degree of openness or have gaps, and at this time the opening is still in an open state, which is very dangerous for small animals.

[0004] Small animals, such as cats, dogs and even birds, are flexible in body and good at finding narrow spaces to shuttle through. Therefore, they may use the tiny openings or incompletely enclosed areas of the fence to quietly approach or even enter the area around the opening. This situation not only violates the safety management regulations of the construction site, but more importantly, it greatly increases the risk of animals accidentally falling into the opening, which may cause serious injuries or even death. Content of the Utility Model

[0005] The purpose of the utility model is to provide a safety protection device for building construction openings, aiming to solve the problem that small animals, such as cats, dogs and even birds, are flexible in body and good at finding narrow spaces to shuttle through. Therefore, they may use the tiny openings or incompletely enclosed areas of the fence to quietly approach or even enter the area around the opening. This situation not only violates the safety management regulations of the construction site, but more importantly, it greatly increases the risk of animals accidentally falling into the opening, which may cause serious injuries or even death.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a safety protection device for building construction openings, including a guardrail, the bottom parts of the two vertical rods on both sides of the guardrail are respectively fixed on the surface of a counterweight seat, and a lower cross bar is connected to the bottom parts of the two vertical rods of the guardrail;

[0007] A threaded inner column is fixedly installed through the center end of the lower cross bar. An adjusting rod is threadedly connected inside the threaded inner column. The bottom of the adjusting rod is fixedly connected to the inner ring of a bearing, and the outer ring of the bottom of the bearing is fixed on the surface of the protective cover.

[0008] In order to enable the adjusting rod to drive the protective cover to move up and down, as an optimization of a safety protection device for building construction openings in the present utility model, a slider is fixedly connected to each side of the protective cover, and the bearing is installed at the center of the protective cover.

[0009] In order to enable the protective cover to move along the outer wall of the side block, as an optimization of a safety protection device for building construction openings in the present utility model, two side blocks are symmetrically installed at the bottom of the lower cross bar. One outer wall of the side block is an arc structure, and the arc outer wall of the side block is in movable contact with the outer wall of the protective cover. The internal dimension of the chute is adapted to the dimension of the slider, and the bottom of the side block and the bottom of the counterweight base are at the same horizontal height.

[0010] In order to install the side block at the bottom of the lower cross bar, as an optimization of a safety protection device for building construction openings in the present utility model, a chute is penetrated and opened in the central area on one side of the arc outer wall of the side block, and a threaded column is fixedly installed at the top of the side block. Two threaded grooves are symmetrically opened at the bottom of the lower cross bar, and each threaded groove is in threaded connection with a threaded column inside.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-5 The utility model provides the following technical solutions: a construction hole safety protection device, comprising a guardrail 1, the bottoms of the vertical bars on both sides of the guardrail 1 are respectively fixed on the surface of a counterweight seat 2, and the bottoms of the two vertical bars of the guardrail 1 are connected to a lower horizontal bar 101;

[0022] An internal thread column 3 is fixedly installed through the center end of the lower cross bar 101, and an adjusting rod 4 is connected to the internal thread of the internal thread column 3. The bottom of the adjusting rod 4 is fixedly connected to the inner ring of the bearing 5, and the bottom outer ring of the bearing 5 is fixed on the surface of the protective cover 6.

[0023] The protective cover 6 is made of plastic. In actual use, the size of the protective cover 6 will be pre-selected according to the size of the construction opening to ensure that the protective cover 6 can completely close the construction opening when used. The protective cover 6 and the bearing 5 are bonded with glue.

[0024] Preferably, a slider 601 is fixedly connected to each side of the protective cover 6, and the bearing 5 is installed at the center of the protective cover 6.
