Abstract
Description
Technical Field
[0001] The utility model relates to an elevator shaft isolation protection device, belonging to the technical field of elevator shaft isolation protection. Background Art
[0002] Elevator shaft hard isolation is an isolation and protection facility installed in the elevator shaft. According to Article 4.2.3 of JGJ80, an isolation and protection facility must be installed every 2 floors and no more than 10m in the elevator shaft. Traditional construction generally uses multiple steel pipes to support the elevator shaft obliquely as a supporting skeleton for hard isolation protection, and lays a template on the skeleton as a closing measure. During the construction process, with the construction of the main structure, isolation and protection facilities in the elevator shaft need to be frequently installed and removed. Therefore, the existing construction method requires construction workers to frequently perform high-altitude operations near the edge, so the risk of construction workers falling from heights is significantly increased, and the construction method is complex, inefficient, and costly.
[0003] Based on this, the existing document (CN 217680695U) discloses a foldable elevator shaft isolation protection device, which includes: a panel layer, a support layer and a clamping leg; the panel layer and the support layer are both foldable structures; the panel layer is fixedly installed above the support layer, and the clamping leg is detachably installed below the support layer; the support layer is arranged above the elevator shaft opening, the clamping leg is arranged in the elevator shaft opening, and the clamping leg is clamped on the inner wall of the elevator shaft opening. The clamping leg is clamped on the inner wall of the elevator shaft opening, and the support layer and the panel layer arranged on the support layer are arranged above the elevator shaft opening, which is quick and convenient during installation, and increases the efficiency of construction. However, during the protection period, this type of protection device relies on the direct contact between the panel layer and the concrete layer on the side of the elevator shaft opening to achieve its support. This method has the problems that it is easy to crush the surface of the concrete layer, the support is unstable, and it is not easy to disassemble and remove. Utility Model Content
[0004] Based on the above, the utility model provides an elevator shaft isolation protection device to overcome the deficiencies of the prior art.
[0005] The technical solution of the utility model is: an elevator shaft isolation protection device, comprising:
[0006] A panel unit, comprising a main panel, a sub-panel and a main beam, wherein the number of the sub-panels is two, the two sub-panels are hinged to the left and right sides of the main panel respectively, at least two main beams are arranged at intervals at the bottom of the main panel, and a support opening is opened on the end of the main beam corresponding to the rear end of the main panel;
[0007] The support unit includes a fixing frame and a socket, the number of the sockets is the same as the number of the support openings, the socket includes a cross bar portion and a vertical bar portion, one end of the cross bar portion is fixed on the fixing frame, the top end of the vertical bar portion is fixed to the other end of the cross bar portion, and a fixing pin is provided at the front end of the cross bar portion, and the fixing pin can be inserted into the support opening to support the main beam.
[0008] In one example, the main panel includes a main frame and a main board layer, the main board layer is installed on the main frame, the main beam is installed on the bottom surface of the main frame, the sub-panel includes a sub-frame and a sub-board layer, the sub-board layer is installed on the sub-frame, and the sub-frame is connected to the main frame through a pin shaft.
[0009] In one example, the main beam is square steel, and the support opening includes a transverse opening and a bottom opening, wherein the transverse opening is formed on a horizontal plane at the end of the main beam, and the bottom opening is formed on a bottom surface at the end of the main beam.

[0012] In one example, the fixing frame is provided with fixing holes at intervals, and the holder is installed in the fixing holes by bolts.
[0013] The beneficial effects of the utility model are as follows: by arranging a support unit including a fixing frame and a holder at the rear end of the main beam, effective suspended support for the panel unit at the elevator door end can be achieved, which can solve the problems of the end of the main panel directly contacting the concrete layer on the side of the elevator shaft opening and crushing the surface of the concrete layer, unstable support, and inconvenient disassembly and removal.

DETAILED DESCRIPTION
[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0022] See also Figures 1 to 5The present embodiment provides an elevator shaft isolation protection device, comprising a panel unit and a support unit. The panel unit comprises a main panel 1, a sub-panel 2 and a main beam 3. The main panel 1 comprises a main frame 101 and a main board layer 102. The main board layer 102 is mounted on the main frame 101. There are two sub-panels 2. The sub-panel 2 comprises a sub-frame 201 and a sub-board layer 202. The sub-board layer 202 is mounted on the sub-frame 201. The sub-frame 201 is connected to the main frame 101 through a pin 203, so that the sub-panel 2 can be rotated and folded relative to the main panel 1. Two main beams 3 are installed at intervals at the bottom of the main frame 101. The main beam 3 is square steel. A support opening 4 is opened at the rear end of the main beam 3. The support opening 4 comprises a horizontal opening and a bottom opening. The horizontal opening is formed on the horizontal plane of the end of the main beam 3 and is in a long semicircular shape. The bottom opening is formed on the bottom surface of the end of the main beam 3. The supporting unit includes a fixing frame 5 and a holder 6. The fixing frame 5 is in the shape of a square strip, and its length is longer than the width of the main panel 1 and the width of the elevator door opening. Fixing holes 501 are arranged at intervals on the fixing frame 5. The holder 6 includes a cross bar portion 601 and a vertical bar portion 602, and is L-shaped. One end of the cross bar portion 601 is installed in the fixing hole 501 by a bolt, and the position can be adjusted as needed. The number of the holders 6 is the same as the number of the supporting openings 4. The top end of the vertical bar portion 602 is fixed to the other end of the cross bar portion 601. A fixing pin 7 is provided at the front end of the cross bar portion 601, and the fixing pin 7 can be inserted into the supporting opening 4 to achieve effective support for the main beam 3.
[0023] In one example, the main panel 1 is arranged at an obtuse angle with respect to the vertical rod of the holder 6, preferably at an upward inclination of 20°, and two rubber blocks 8 are installed at the front end of the main panel 1, and the front end surfaces of the rubber blocks 8 are arranged as vertical surfaces. The rubber blocks 8 allow the main panel 1 to naturally form a slope of about 20° after installation, thereby reducing the impact of objects dropped in the well on the protective device, and automatically collecting construction waste at the door opening for easy cleaning.
[0024] In one example, a gap-shielding plate 9 is detachably mounted on the end of the main panel 1 corresponding to the fixing frame 5, and the gap-shielding plate 9 is used to close the gap between the protective device and the elevator shaft door opening.
[0025] In one example, the main beam 3 is a square steel of size 80, the main frame 101 and the sub-frame 201 are both square steel of size 50, and the main plate layer 102 and the sub-plate layer 202 are 3 mm thick patterned steel plates.
[0026] The working principle of the above elevator shaft isolation protection device is as follows:
[0027] During installation, first fold the two side panels 2 inward, then vertically insert the support opening 4 of the main beam 3 into the fixing pin 7 of the holder 6, so that the main beam 3 can rotate around the fixing pin 7, and then slowly lay the protective device flat in the elevator shaft. At this time, the rubber block 8 is pressed against the opposite wall of the elevator shaft. Because the end face of the rubber block 8 is inclined and the length of the protective device is limited, the protective device naturally forms a slope of about 20° after installation, thereby reducing the impact of objects falling in the shaft on the protective device, and automatically collecting construction waste to the door opening for easy cleaning. At the same time, the vertical rod part 602 is clamped on the inner wall of the elevator shaft opening, the horizontal rod part 601 is horizontally installed on the outer wall of the elevator shaft door opening, and the fixing frame 5 is fixed on the outer side of the elevator shaft door opening. Through the cooperation of the fixing frame 5 and the holder 6, effective suspended support for the panel unit (elevator door end) can be achieved, which can solve the problem that the end of the main panel 1 directly contacts the concrete layer on the side of the elevator shaft opening and crushes the surface of the concrete layer, the support is unstable, and it is inconvenient to disassemble and remove. After the protective device is laid flat, the auxiliary panel 2 is folded outward and then the gap-shielding plate 9 is installed to close the gap between the protective device and the elevator shaft door opening after being folded and expanded, so as to achieve a full sealing effect of the elevator shaft and the elevator shaft door opening.
[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
