Description

Technical Field

[0001] This invention relates to the field of exterior wall panel construction technology, and in particular to a temporary fixing clamp for preventing fall of EMC exterior wall panels in prefabricated buildings. Background Technology

[0002] In prefabricated building construction, EMC exterior wall panels are widely used due to their advantages such as lightweight, high strength, and good durability. The installation quality directly affects the overall structural safety and appearance of the building. When installing EMC exterior wall panels, the upper wall panel must first be overlapped on the top of the lower wall panel, and then permanent fixation is achieved through grouting. The temporary fixing process before grouting is the key to preventing the wall panel from falling and ensuring construction safety. However, the existing temporary fixing methods for EMC exterior wall panels have many technical defects and cannot meet the requirements of efficient and safe construction.

[0003] Traditional temporary fixing tools lack stability, and most of them use a single steel pipe support or simple buckle fixing, which can only limit the wall panel from one side or a part, and cannot form a stable surrounding clamping frame. Under the influence of external construction forces or the wall panel's own weight, the clamp is prone to displacement, loosening of the wall panel, or even falling risks. This is especially true for high-rise prefabricated buildings, where the safety hazards are more prominent. Therefore, developing an EMC exterior wall panel anti-fall temporary fixing clamp with stable clamping, convenient operation, adaptability to hoisting, and easy disassembly has become a key requirement to solve industry pain points and promote the upgrading of prefabricated building construction technology. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies in the existing technology by proposing a temporary fixing clamp for preventing fall of prefabricated building EMC exterior wall panels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temporary fixing clamp for preventing fall of EMC exterior wall panels in prefabricated buildings includes a left clamp and a right clamp. The outer walls of both the left and right clamps are provided with sliding grooves, and sliding strips are slidably installed within these grooves. An installation frame is fixedly installed on the outer wall of each sliding strip, and an installation plate is fixedly installed at the end of the installation frame. The clamp also includes:

[0007] A clamping mechanism, which is disposed in the mounting frame, is used to clamp the EMC outer wall panel between the left clamp and the right clamp;

[0008] A connecting mechanism is provided on the outside of the left clamp and the right clamp, and is used to connect the left clamp and the right clamp to each other;

[0009] A hoisting mechanism is provided at the top of the left and right clamps and is used to cooperate with the crane to lift the left and right clamps.

[0010] As a further embodiment of the present invention: the clamping mechanism includes a first telescopic cylinder fixedly installed in the mounting plate, a movable plate fixedly installed at the telescopic end of the first telescopic cylinder, a movable rod movably installed through the outer wall of the movable plate, a clamping plate fixedly installed at one end of the movable rod and located outside the mounting frame, a push plate fixedly installed at the other end of the movable rod and located within the mounting frame, a first spring sleeved on the outer side of the movable rod, one end of the first spring connected to the movable plate and the other end of the first spring connected to the push plate, and a locking assembly provided in the mounting frame for locking the position of the push plate.

[0011] As a further embodiment of the present invention: the locking assembly includes a second telescopic cylinder fixedly installed in the mounting frame, and a supporting block is fixedly installed at the telescopic end of the second telescopic cylinder. A first inclined surface is provided on the upper surface of the supporting block. A second inclined surface that cooperates with the first inclined surface is provided at the end of the push plate facing the supporting block. A limiting rod penetrating the mounting frame is fixedly installed on the lower surface of the supporting block. A pressure sensor is also fixedly installed on the inner wall of the mounting frame, and the pressure sensor is located between the moving plate and the mounting frame. A positioning assembly is also provided on the outer side of the mounting plate to limit the position of the mounting frame.

[0012] As a further embodiment of the present invention: the positioning component includes a positioning rod that penetrates the mounting plate, one end of the positioning rod is fixedly fitted with a handle, the outer walls of the left clamp and the right clamp are provided with positioning holes that are evenly distributed, and the other end of the positioning rod is inserted into the positioning hole.

[0013] As a further embodiment of the present invention: the connecting mechanism includes insert rods evenly distributed on the outer sides of the left clamp and the right clamp, with the insert rods on the outer sides of the left clamp and the right clamp being staggered. The outer walls of the left clamp and the right clamp also have equally distributed insertion slots, with the insertion slots and insert rods being staggered. The outer walls of the left clamp and the right clamp have equally distributed side plates, and a locking block is movably installed in the side plate. A fixing plate is fixedly installed on the lower surface of the locking block. The fixing plate and the side plate are connected by a second spring. The outer wall of the insert rod has a locking hole that cooperates with the locking block. The outer side of the locking block also has a third inclined surface, which faces the insertion slot direction.

[0014] As a further embodiment of the present invention: a frame is fixedly installed on the lower surface of the fixing plate, and a crossbar is movably installed in the frame. A connecting rod is fixedly installed on the outer wall of the crossbar, and a handle is fixedly installed at the end of the connecting rod.

[0015] As a further embodiment of the present invention: the hoisting mechanism includes a docking cylinder fixedly installed at the top of the left clamp and a docking rod fixedly installed at the top of the right clamp, and the docking rod is inserted into the docking cylinder, and an arc-shaped groove is provided on the outer side of the docking cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The prefabricated building EMC exterior wall panel anti-fall temporary fixing clamp provided by the present invention attaches the left and right clamps to the left and right sides of the exterior wall panel respectively, ensuring that the top height is aligned and fits against the side wall, avoiding positional deviation during locking; the left and right clamps are locked by the connecting mechanism, so that they move from both sides towards the middle, together fitting on the outer side of the upper and lower wall panels to form a stable clamping frame, effectively preventing the clamps on one side from shifting, and providing a precise and stable foundation for subsequent fixing.

[0018] Move the mounting frames on the outside of the left and right clamps so that the mounting frames on the left and right sides are symmetrically distributed on both sides of the upper and lower wall panels to ensure uniform clamping force; activate the clamping mechanism to clamp the outer wall of the wall panel from the left and right directions, and combine with the frame fixation of the left and right clamps to achieve double fixation of the upper and lower wall panels, ensuring that the wall panels remain relatively stable before grouting and effectively avoiding the risk of falling.

[0019] After grouting is completed and the grout has solidified, first release the clamping mechanism, then disassemble the connecting mechanism to separate the left and right clamps, and finally remove the clamps from both sides of the wall panel. The entire disassembly process does not require complicated operations, avoiding damage to the fixed wall panel and ensuring construction quality and ease of disassembly.

[0020] Furthermore, the left and right clamps can be locked in advance through the connecting mechanism, and the crane can be connected to the hoisting mechanism on the clamps to directly hoist the assembled clamps to the outside of the wall panel. This design eliminates the step of separately moving the clamps, simplifies the operation process, reduces construction connection time, and significantly improves the overall construction efficiency.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-7 As shown, a temporary fixing clamp for preventing fall of prefabricated building EMC exterior wall panels provided in an embodiment of the present invention includes a left clamp 101 and a right clamp 102. The outer walls of both the left clamp 101 and the right clamp 102 are provided with sliding grooves 103, and sliding strips 104 are slidably installed in the sliding grooves 103. An installation frame 105 is fixedly installed on the outer wall of the sliding strip 104, and an installation plate 106 is fixedly installed at the end of the installation frame 105. The clamp also includes: a clamping mechanism disposed in the installation frame 105 for clamping the EMC exterior wall panel between the left clamp 101 and the right clamp 102; a connecting mechanism disposed on the outer sides of the left clamp 101 and the right clamp 102 for connecting the left clamp 101 and the right clamp 102 to each other; and a hoisting mechanism disposed at the top of the left clamp 101 and the right clamp 102 for cooperating with a crane to hoist the left clamp 101 and the right clamp 102.

[0031] After one EMC exterior wall panel is installed on top of another, before grouting and fixing, the two sets of EMC exterior wall panels need to be temporarily fixed. First, place the left clamp 101 against the left side of the EMC exterior wall panel and the right clamp 102 against the right side of the EMC exterior wall panel, ensuring that the tops of the left clamp 101 and the right clamp 102 are aligned and that they are in contact with the sidewalls of the exterior wall panels to avoid positional deviations during subsequent locking. Then, lock the left clamp 101 and the right clamp 102 together using the connecting mechanism. The left clamp 101 and the right clamp 102 will then... Do not move the clamps from the left and right sides of the outer wall panel towards the center; instead, fit them together on the outer sides of the upper and lower EMC outer wall panels to form a stable clamping frame. This prevents the clamps on one side from shifting during subsequent operations. Then, move the mounting frames 105 on the outer side of the left clamp 101 and the right clamp 102 respectively. Place one set of mounting frames 105 on the left clamp 101 on the left side of the lower EMC outer wall panel and the other set on the left side of the upper EMC outer wall panel. Simultaneously, place one set of mounting frames 105 on the right side of the lower EMC outer wall panel and the other set on the right side of the lower EMC outer wall panel. Frame 105 is positioned on the right side of the upper EMC exterior wall panel, ensuring symmetrical distribution of the mounting frames 105 on both sides to guarantee uniform clamping force. Then, the clamping mechanisms within the mounting frames 105 of the left clamp 101 and the right clamp 102 are activated, clamping the exterior wall panels from the left and right sides respectively. At this point, the upper and lower EMC exterior wall panels are jointly fixed by the left clamp 101, right clamp 102, and clamping mechanisms, maintaining relative stability and effectively preventing the EMC exterior wall panels from falling before grouting. After the grouting operation is completed and the grout has solidified, the panels are then... Release the clamping mechanisms on the left clamp 101 and right clamp 102 from the EMC exterior wall panel, then disassemble the connecting mechanism to separate the left clamp 101 and right clamp 102. Finally, remove them from both sides of the exterior wall panel. Alternatively, a convenient hoisting method can be used. First, lock the left clamp 101 and right clamp 102 in advance through the connecting mechanism, then connect the crane to the hoisting mechanism on the left clamp 101 or right clamp 102, and directly hoist the assembled left clamp 101 and right clamp 102 to the outside of the EMC exterior wall panel, further simplifying the operation process and improving construction efficiency.

[0032] As one embodiment of the present invention, please refer to Figure 4 , Figure 5 and Figure 6The clamping mechanism includes a first telescopic cylinder 201 fixedly installed in the mounting plate 106. A movable plate 202 is fixedly installed at the telescopic end of the first telescopic cylinder 201. A movable rod 203 is movably installed through the outer wall of the movable plate 202. A clamping plate 206 is fixedly installed at one end of the movable rod 203, and the clamping plate 206 is located outside the mounting frame 105. A push plate 205 is fixedly installed at the other end of the movable rod 203, and the push plate 205 is located in the mounting frame 105. A first spring 204 is also sleeved on the outside of the movable rod 203. One end of the first spring 204 is connected to the movable plate 202, and the other end of the first spring 204 is connected to the push plate 205. A locking assembly is also provided in the mounting frame 105. The component is used to lock the position of the push plate 205. When it is necessary to clamp the EMC exterior wall panel, the first telescopic cylinder 201 can drive the moving plate 202 to move. The moving plate 202 drives the push plate 205, the movable rod 203 and the clamping plate 206 to move together with the first spring 204 until the clamping plate 206 is in contact with the outer wall of the EMC exterior wall panel and the first spring 204 is in a suitable tension state. At this time, the clamping plate 206 and the EMC exterior wall panel are in a stable contact state, which will trigger the locking component to lock the position of the push plate 205, thereby indirectly locking the position of the clamping plate 206. This allows the EMC exterior wall panel to maintain relative stability with the left clamp 101 and the right clamp 102.

[0033] As one embodiment of the present invention, please refer to Figure 4 , Figure 5 and Figure 6 The locking assembly includes a second telescopic cylinder 303 fixedly installed in the mounting frame 105, and a retaining block 302 fixedly installed at the telescopic end of the second telescopic cylinder 303. The upper surface of the retaining block 302 is provided with a first inclined surface. The end of the push plate 205 facing the retaining block 302 is provided with a second inclined surface that cooperates with the first inclined surface. A limiting rod 304 penetrating the mounting frame 105 is fixedly installed on the lower surface of the retaining block 302. A pressure sensor 301 is also fixedly installed on the inner wall of the mounting frame 105, and the pressure sensor 301 is located on the moving plate 202. A positioning component is also provided on the outer side of the mounting plate 106 between the mounting frame 105 and the mounting frame 105 to limit the position of the mounting frame 105. When the moving plate 202 moves and comes into contact with the pressure sensor 301 in the mounting frame 105, it indicates that the first spring 204 is in a suitable tension state. At this time, the second telescopic cylinder 303 will be triggered to drive the abutment block 302 to move upward. By the first inclined surface at the top of the abutment block 302 and the second inclined surface at the bottom of the push plate 205, the position of the push plate 205 can be locked, which is very convenient to use.

[0034] As one embodiment of the present invention, please refer to Figure 4 , Figure 5 and Figure 6The positioning component includes a positioning rod 402 that penetrates the mounting plate 106. One end of the positioning rod 402 is fixedly mounted with a handle 401. The outer walls of the left clamp 101 and the right clamp 102 are provided with equally spaced positioning holes 403, and the other end of the positioning rod 402 is inserted into the positioning hole 403. When it is necessary to move the position of the mounting frame 105, the handle 401 can be held to pull the positioning rod 402 out of the positioning hole 403 to release the locking of the mounting frame 105. Then the positioning rod 402 can be reinserted into the appropriate positioning hole 403. It is very convenient to use.

[0035] As one embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 4 The connecting mechanism includes insert rods 501 evenly distributed on the outer sides of the left clamp 101 and the right clamp 102, with the insert rods 501 on the outer sides of the left clamp 101 and the right clamp 102 being staggered. The outer walls of the left clamp 101 and the right clamp 102 also have equally distributed insertion slots 502, with the slots 502 and the insert rods 501 being staggered. The outer walls of the left clamp 101 and the right clamp 102 have equally distributed side plates 504, and a locking block 505 is movably installed in the side plate 504. A fixing plate 506 is fixedly installed on the lower surface of the locking block 505, and the fixing plate 506 and the side plate 504 are connected by a second spring 507. The outer wall of the insert rod 501 has a locking hole 503 that mates with the locking block 505. The outer side of the locking block 505 also has... A third inclined surface is provided, and the third inclined surface faces the insertion port 502. During the process of the left clamp 101 and the right clamp 102 docking with each other, the insertion rod 501 will be directly inserted into the insertion port 502. When the end of the insertion rod 501 passes through the insertion port 502, the end of the insertion rod 501 will contact the third inclined surface on the outside of the locking block 505 and push the locking block 505 to move downward. At the same time, the second spring 507 will be stretched until the insertion rod 501 completely passes over the locking block 505 and the locking hole 503 in the insertion rod 501 docks with the locking block 505. At this time, the left clamp 101 and the right clamp 102 are just in a close-fitting state. Under the reset action of the second spring 507, the locking block 505 can be springed into the locking hole 503, thereby achieving the purpose of quickly locking the left clamp 101 and the right clamp 102.

[0036] As one embodiment of the present invention, please refer to Figure 3A frame 601 is fixedly installed on the lower surface of the fixing plate 506, and a crossbar 602 is movably installed in the frame 601. A connecting rod 603 is fixedly installed on the outer wall of the crossbar 602, and a grip 604 is fixedly installed at the end of the connecting rod 603. When it is necessary to release the lock between the left clamp 101 and the right clamp 102, the grip 604 can be directly gripped and pulled down. The grip 604 can then drive the crossbar 602, the fixing plate 506, and the locking block 505 to move down together, so that the locking block 505 moves out of the lock hole 503, realizing a quick unlocking operation.

[0037] As one embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 4 The hoisting mechanism includes a docking cylinder 701 fixedly installed at the top of the left clamp 101 and a docking rod 702 fixedly installed at the top of the right clamp 102. The docking rod 702 is inserted into the docking cylinder 701. An arc groove is provided on the outer side of the docking cylinder 701. When the left clamp 101 and the right clamp 102 are spliced ​​together, the docking rod 702 at the top of the right clamp 102 will also be inserted into the docking cylinder 701 at the top of the left clamp 101. At this time, the clamp can be directly hoisted to the outside of the EMC exterior wall panel by hooking the hook of the crane onto the outside of the docking cylinder 701. The hook can be hooked onto the arc groove on the outside of the docking cylinder 701, which makes the hoisting process more stable and the use effect better.

[0038] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
