Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a construction frame that is easy to move. Background Technology

[0002] A scaffold is a work platform erected during construction or high-altitude operations to ensure smooth progress.

[0003] In the prior art, utility model patent application number CN202420597012.6 discloses a mobile frame for wall construction in building engineering, including a support frame, with moving wheels installed at the bottom of the support frame, an installation sleeve fitted on the outer side of the support frame, an auxiliary bracket fixed to one side of the installation sleeve, a sleeve fixed to one side of the auxiliary bracket, a screw installed inside the sleeve, a handle fixed above the screw, and a stabilizing block fixed below the screw; in this mobile frame for wall construction in building engineering, after the device is moved to a new position, the construction worker can rotate the handle to drive the screw to extend and retract inside the sleeve, causing the stabilizing block to descend until it is pressed against the ground, thus providing support for the support frame, and the support frame will not shift when the construction worker stands on the platform.

[0004] However, the mobile frames used for wall construction in the above-mentioned building projects are not convenient for connecting and fixing multiple mobile frames. When multiple mobile frames need to be used in combination, the stability between the mobile frames is poor and needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a construction frame that is easy to move and facilitates the connection and fixation between construction frames, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mobile construction frame includes a frame body with a footboard mounted on the top. The frame body has vertically extending support columns with casters mounted on their lower ends. A fixed base is fixedly mounted on the support column, and a sliding rod is slidably mounted on the fixed base. One end of the sliding rod has a hook for hooking onto a support column on an adjacent construction frame, and the other end of the sliding rod has a base plate. An adjusting screw for pressing against the fixed base is screwed onto the base plate, and the adjusting screw is parallel to the sliding rod.

[0008] As a further improvement, the top of the frame is provided with two parallel upper crossbars, and the pedal is detachably installed between the two upper crossbars. The two ends of the pedal are respectively fixedly installed with buckles for resting on the corresponding upper crossbars. Movable plates are also slidably installed at both ends of the frame. The sliding direction of the two movable plates is on the same straight line. The two movable plates are respectively fixedly installed with pins on the sides away from each other. The two upper crossbars are respectively provided with insertion holes for the corresponding pins to be inserted. The pedal is provided with a spring for driving the pins to be inserted into the insertion holes.

[0009] As a further improvement, handles are fixedly installed on the sides of the two movable plates that are close to each other.

[0010] As a further improvement, a pull rope is connected between the two handles.

[0011] As a further improvement, a support seat is fixedly installed on the support column, and a vertically extending threaded post is screwed onto the support seat. An anti-slip support is fixedly installed at the lower end of the threaded post.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] After attaching the buckle on the pedal to the upper crossbar, inserting the pin into the hole on the upper crossbar improves the stability of the pedal installation, prevents the pedal from accidentally falling off, and enhances safety.

[0014] Workers can pull the rope to disengage the pins on both sides from the socket, so that the pedal can be removed from the top of the frame. The disassembly of the pedal can be completed by a single person, and the disassembly of the pedal is very convenient.

[0015] After the construction frame is moved, the rotating threaded column drives the anti-slip support downward to contact the ground. The friction between the anti-slip support and the ground prevents the construction frame from shifting.

[0016] When multiple construction frames are used in combination, the hook on the right-side support of the construction frame hooks onto the corresponding left-side support of the adjacent construction frame. Then, the adjusting screw is rotated so that one end of it presses against the left side of the fixing seat to the right. The adjusting screw then reacts to the base plate and drives the two sliding rods to move to the left. The sliding rods pull the support on the adjacent construction frame to the left and fit against the right side of the fixing seat through the hook, thereby connecting and fixing the two adjacent construction frames. This can improve the stability when multiple construction frames are used in combination and meet the needs of large-scale construction. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4As shown, a mobile construction scaffold includes a frame body 1. The frame body 1 includes two uprights 2 arranged opposite each other on the left and right. Each upright has two vertically extending support columns 3 arranged opposite each other on the front and back. An upper horizontal bar 4 and a lower horizontal bar 5 arranged opposite each other on the back and front are welded between the support columns 3. Both the upper horizontal bar 4 and the lower horizontal bar 5 extend horizontally front and back. A vertically extending upright 6 is also welded between the middle of the upper horizontal bar 4 and the lower horizontal bar 5. A plurality of horizontally extending footboards 7 are arranged vertically and evenly at intervals between the upright 6 and one of the support columns 3, which facilitates climbing by workers. An X-shaped connecting frame 8 is bolted between the two uprights 2 and between the left and right opposite support columns 3 to improve the overall stability of the frame body 1.

[0025] like Figure 2 and Figure 3 As shown, a horizontally arranged footboard 9 is installed on the top of the frame 1. A rectangular frame 10 is welded to the bottom of the footboard 9, supporting the bottom edge of the footboard 9. Multiple support rods 11, evenly spaced on the left and right sides, are also welded inside the frame 10 to improve the load-bearing capacity of the footboard 9. The footboard 9 is detachably installed between two upper crossbars 4. Buckles 12 for resting on the corresponding upper crossbars 4 are welded to the left and right ends of the frame 10, with two buckles 12 facing each other at the front and back at the left and right ends of the frame 10. The buckles 12 are C-shaped with their openings facing downwards and fit snugly against the outer wall of the upper crossbars 4, facilitating the removal of the footboard 9. In this embodiment, two footboards 9 arranged side-by-side are detachably installed on the top of each frame 1.

[0026] Two guide rods 13 arranged side-by-side are fixedly installed on the inner sides of the left and right ends of the frame 10. A movable plate 14 is slidably installed on each of the two guide rods 13 at the same end, and the sliding direction of the two movable plates 14 is on the same straight line. A pin 15 is welded to the side of the two movable plates 14 that is away from each other. The frame 10 is provided with a clearance hole for the pin 15 to pass through. The two upper crossbars 4 are provided with a socket 16 for the corresponding pin 15 to be inserted. After the buckle 12 on the pedal 9 is placed on the upper crossbar 4, the stability of the pedal 9 is improved by inserting the pin 15 into the socket 16 on the upper crossbar 4, thereby preventing the pedal 9 from accidentally falling off. One end of the guide rod 13 is provided with an external thread and screwed onto the frame 10. The other end of the guide rod 13 is welded with a stop 17 to prevent the movable plate 14 from falling off. In order to prevent the pin 15 from accidentally falling out of the socket 16, a spring 18 is sleeved on the guide rod 13 located between the stop 17 and the movable plate 14.

[0027] Handles 19 are welded to the sides of the two movable plates 14 that are close to each other. By pulling the handles 19, the pins 15 are disengaged from the sockets 16, and the pedal 9 can be removed from the top of the frame 1. In addition, a pull rope 20 is connected between the two handles 19. The two ends of the pull rope 20 are tied to the two handles 19 respectively, so that the worker can pull the pull rope 20 to disengage the pins 15 on both sides from the sockets 16 at the same time. The disassembly of the pedal 9 can be completed by a single person.

[0028] The lower end of the support column 3 is equipped with a movable wheel 21 to facilitate the movement of the construction frame. In addition, a support base 22 is fixedly installed on the support column 3 by bolts. The support base 22 extends inward to the two uprights 2. A vertically extending threaded column 24 is screwed onto the support base 22. A throttle is fixedly installed at the upper end of the threaded column 24, and an anti-slip support 23 is fixedly installed at the lower end of the threaded column 24 by bolts. After the construction frame is moved, rotating the threaded column 24 causes the anti-slip support 23 to contact the ground downward. The friction between the anti-slip support 23 and the ground prevents the construction frame from shifting.

[0029] In this embodiment, fixing seats 25 are respectively fixedly installed on the two support columns 3 on the right side of the construction frame by bolts, such as Figure 4 As shown, the right side of the fixing base 25 is arc-shaped to match the support column 3; the fixing base 25 is provided with a guide hole that runs horizontally through it. Two guide holes are arranged side by side, and a slide rod 26 is slidably installed in each of the two guide holes. The right end of the slide rod 26 is welded with a hook body 27 for hooking the corresponding support column 3 on the left side of the adjacent construction frame. The hook body 27 is U-shaped with its opening facing the fixing base 25. The left ends of the two slide rods 26 are fixedly installed on the same base plate 28 by bolts. An adjusting screw 29 for pressing against the left side of the fixing base 25 is screwed onto the base plate 28. The adjusting screw 29 is arranged parallel to the slide rod 26.

[0030] When multiple construction frames are used in combination, the hook 27 on the right support column 3 of the construction frame hooks the corresponding left support column 3 of the adjacent construction frame. Then, the adjusting screw 29 is rotated so that one end of it presses against the left side of the fixing seat 25 to the right. The adjusting screw 29 then reacts to the base plate 28 and drives the two sliding rods 26 to move to the left. The sliding rods 26 pull the support column 3 of the adjacent construction frame to the left and fit against the right side of the fixing seat 25 through the hook 27, thereby achieving the connection and fixation of the two adjacent construction frames. This can improve the stability when multiple construction frames are used in combination and meet the needs of large-scale construction.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
