Description

Technical Field

[0001] The utility model relates to edge hole protection equipment used in building construction. Background Art

[0002] During the construction process, many openings will be left. Some openings are used for passage, and most of the openings are used for the later installation of doors and windows. Protection needs to be installed at the openings in the exterior walls or in the elevator shaft to prevent people from falling.

[0003] There are two existing protection methods. One is through safety warning equipment, namely ice cream buckets, temporary guardrails, etc. This type of protection is less effective and has more loopholes.

[0004] The other method is to use masking, that is, to fix and install door panels at the position of the opening. This installation method has a serious light blocking effect and affects the internal construction of the building.

[0005] Based on the above problems, we designed a protective device for edge openings used in construction that can be quickly assembled and has high protection. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a protective device for edge openings used in building construction which can be quickly built and has high protectiveness.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 7 The shown device is a protective device for edge openings used in construction, comprising a cross bar structure 1, and a side bar structure 2 slidably assembled with the cross bar structure 1, a support plate structure 3 is installed at the end of the side bar structure 2 away from the cross bar structure 1, and a safety net 4 is fixed below the cross bar structure 1, and the safety net 4 is slidably assembled with the side bar structure 2.

[0032] In the above technical solution, the length of the side strip structure 2 sliding outward is adjusted according to the width of the opening, and the support plate structure 3 is used to support both sides of the opening, and the safety net 4 is used to shield and protect the exposed space under the cross bar structure 1 and the side strip structure 2.

[0033] See also Figure 1 and Figure 2 As shown, the crossbar structure 1 includes a crossbar 101, and slide grooves 102 are arranged at both ends of the crossbar 101. The slide grooves 102 at both ends are disconnected, and a first slide groove 103 is arranged at the groove wall of the slide groove 102. On the side of the crossbar 101, an empty groove 104 is arranged above the slide groove 102, and plug holes (not shown) are arranged at the two ends of the top of the crossbar 101. The plug holes penetrate downward, and a locking rod 105 is assembled through the plug holes. A limiting portion 106 is arranged on the locking rod 105, and the limiting portion 106 is located at the position of the locking rod 105. A pull ring 107 is provided at the upper end of the locking rod 105 in the empty slot 104, and a spring 108 is provided on the rod body of the locking rod 105. The spring 108 is located in the empty slot 104, and the upper end is limited by the top surface of the empty slot 104, and the lower end of the spring 108 is limited by the limiting part 106. The side strip structure 2 is assembled in the slide slot 102 and is guided by the first slide slot 103. The locking rod 105 limits the sliding of the side strip structure 2, and the safety net 4 is fixed at the middle position of the bottom of the cross bar 101.

[0034] In the above technical solution, the side strip structure 2 will slide outward to lift the locking rod, and after the locking rod returns to its original position, it will limit the retraction of the side strip structure 2, thereby avoiding the retraction of the side strip structure 2 during the protection process.

[0035] The outward sliding length of the side strip structure 2 is adjustable to accommodate holes of different widths.

[0036] See also Figures 1 to 5 As shown, the side strip structure 2 includes a side strip 201, and the side strip 201 is slidably assembled with the slide groove 102. The two sides of the side strip 201 are provided with slide strips 202 that match the first slide groove 103. The slide strip 202 can limit the side strip 201 in the slide groove 102 to prevent the side strip 201 from falling downward. The top of the side strip 201 is provided with a ratchet 203. When the side strip 201 is pulled outward along the slide groove 102, the ratchet 203 lifts the locking rod 105, and the side strip 201 can slide out smoothly at this time. When the side strip 201 moves toward the direction of the cross bar 101 When the locking rod 105 is locked, the displacement of the ratchet 203 is blocked by the locking rod 105. This technical means can prevent the side strip 201 from retracting. A T-shaped slide 204 is provided at the bottom of the side strip 201. The slide 204 passes through the end facing the cross bar 101. The slide 204 is screwed into a limiting screw 205 at a position close to the cross bar 101. The safety net 4 slides with the slide 204 and is blocked from sliding by the limiting screw 205. A mounting plate 206 is provided at the end of the side strip 201 away from the cross bar 101, and the support plate structure 3 is installed through the mounting plate 206.

[0037] In the above technical solution, the safety net 4 can be unfolded or folded along the slide 204. When the indoor hole is temporarily closed, if there is a need for passage, the safety net 4 can be slid and folded, and then enter and exit through the bottom of the side strip 201.

[0038] See also Figure 5 As shown, the plate surface of the mounting plate 206 is penetrated by through holes and threaded holes, and the support plate structure 4 includes an L-shaped support plate 401, a rack 411 is arranged on the inner end surface of the support plate 401, and a guide rod 412 is arranged on the outer end surface of the support plate 401. After the guide rod 412 passes through the through hole, it cooperates with a limiting nut 413, and a first spring 414 is arranged on the guide rod 412, and the first spring 414 acts between the support plate 401 and the mounting plate 206. A locking screw 415 is installed through the threaded hole, and the locking screw 415 is screwed out to support the support plate 401.

[0039] In the above technical solution, the rack 411 is in contact with the inner wall of the hole to increase firmness and reduce slippage.

[0040] Through the action of the first spring 414, a certain pre-tightening force is maintained between the support plate 401 and the wall, so that a single person can complete the installation of the device.

[0041] The locking screw 415 can lock the position of the support plate 401, so that the support plate 401 can firmly support the inner wall of the hole.

[0042] See also Figure 1 and Figure 6 As shown, the safety net 4 includes a net frame 41 and a net body 42 installed on the inner side of the net frame 41. Connecting cloths 43 are provided on both sides and the bottom of the net frame 41. Through holes 44 are processed on the connecting cloths 43. The middle part of the net frame 41 is fixed to the cross bar 101. A plurality of T-shaped sliders 45 are provided on the top of the net frame 41. The T-shaped sliders 45 slide along the slideway 204 and are limited in sliding by the limit screws 205.

[0043] In the above technical solution, when protecting the opening of the outer wall, bolts need to be driven into both sides of the opening to fix the connecting cloth 43 to the bolts. At this time, the safety net 4 is fixed to prevent people from accidentally falling from the safety net.

[0044] The protection methods are as follows:

[0045] Intercept the crossbar horizontally in the opening, and pull out the side strip structure to both sides. The support plate structure at one end first rests against one end of the opening, and the support plate structure at the other end does not contact the inner wall of the opening. Then move the crossbar up to the required interception height, and continue to pull out the side strip structure at the other end until the support plate structure on the other side contacts the inner wall of the opening to complete the temporary erection. Then unscrew the locking screws to complete the final fixation, and finally stretch the safety net to complete the protection.

[0046] The side bars and crossbars are made of aluminum alloy, which is lightweight and easy to install by one person.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
