Description

Technical Field

[0001] The invention relates to an auxiliary device for metal roof construction, in particular to a windproof device for metal roof construction. Background Art

[0002] With the increasing number of public buildings such as stadiums, conference and exhibition centers in actual projects, the use of metal roofs is also increasing. In the process of metal roof construction, windy and rainy weather is often encountered. In order to prevent wind and rain from damaging or polluting the unfinished metal roof structure layer, thereby causing the unfinished metal roof structure layer to lose its original function. Therefore, it is necessary to set a corresponding windproof device between the completed metal roof and the ground to prevent the unfinished metal roof structure layer from being damaged or polluted.

[0003] like Figure 1 As shown, the existing windproof device for metal roof construction generally includes a rainproof tarpaulin 100, and the front end of the rainproof tarpaulin 100 is effectively fixed and clamped on the roof panel ridge 300 of the completed metal roof through a plurality of clamps 200 arranged at intervals, and then the rainproof tarpaulin 100 is covered on the unfinished metal roof structural layer 400, and the rear end of the rainproof tarpaulin 100 is tensioned and stretched downward to the corresponding ground, and the rear end of the rainproof tarpaulin 100 is compacted by a corresponding steel structure or other heavy object 500.

[0004] Such a windproof device for metal roof construction has the following defects in actual use: 1) The rainproof tarpaulin is mainly fixed by clamps arranged at intervals. Since the wind-receiving area of ​​the rainproof tarpaulin is large, it is easy to form a large force on the clamp after it is exposed to the wind, resulting in obvious stress concentration between the clamp and the roof panel spine, which in turn causes compression deformation of the roof panel spine, which damages the roof panel spine and causes the clamping between the clamp and the roof panel spine to fail, thereby causing the front end of the rainproof tarpaulin to fail to be fixed; 2) Heavy objects such as steel components are mainly compacted and fixed to the rainproof tarpaulin by compaction. When the rainproof tarpaulin swings upward due to the wind, it is easy to generate an upward thrust on the inner end of the heavy object, so that the heavy object is easy to be "turned over" with the bottom of its outer end as the fulcrum, thereby causing the rear end of the rainproof tarpaulin to fail to be fixed; 3) On rainy days, a large amount of rainwater is easy to be diverted to the ground of the construction site along with the rainproof tarpaulin, causing a large amount of rainwater to be flushed onto the construction site, thereby causing damage to the construction site of the construction site.

[0005] Therefore, the purpose of the present invention is to design a metal roof construction windproof device that can effectively ensure the clamping effect between the clamp and the roof panel spine, thereby improving the fixing effect of the front end of the rainproof tarpaulin; and can improve the fixing effect of the rear end of the rainproof tarpaulin without increasing the weight of the heavy object; and can effectively divert and collect rainwater diverted by the rainproof tarpaulin on rainy days.

[0012] A corresponding buffer rubber block is fixed in an extruded state between the middle parts of the first locking clamp and the second locking clamp, the bottom of the buffer rubber block abuts against the top of the roof panel ridge, and the upper side of the folded part of the rainproof tarpaulin is clamped between the buffer rubber block and the first locking clamp and the second locking clamp.

[0013] A corresponding limiting groove is arranged on the upper side of the first locking clamp, a limiting protrusion which is snapped into the limiting groove is arranged on the upper part of the second locking clamp, corresponding fixing protrusions are arranged inwardly in the middle parts of the first locking clamp and the second locking clamp respectively, and the top of the buffer rubber block is pressed and abutted against the fixing protrusions of the first locking clamp and the second locking clamp.

[0014] A corresponding fastening groove is laterally arranged on the upper surface of the fastening piece, the fastening piece is arranged on the outer side surface of the rainproof tarpaulin, and a plate-shaped fixing piece matched with the fastening piece is arranged on the inner side surface of the rainproof tarpaulin. The fastening piece and the plate-shaped fixing piece are fixedly clamped to the rear end of the rainproof tarpaulin by bolt locking.

[0015] The bottom end surface of the counterweight block is arranged in a horizontal plane shape, and corresponding supporting rollers are rotatably installed on both sides of the inner end of the counterweight block, and the bottom ends of the supporting rollers are arranged flush with the bottom end surface of the counterweight block, and a group of handles for moving the counterweight block are fixed outwardly at the outer end of the counterweight block.

[0016] The middle part of the counterweight block is concavely provided with a corresponding limiting groove, the hook fastener is fixedly connected to the limiting groove of the counterweight block, and the top of the hook fastener is folded inward in an inverted L shape and is provided with a hook portion adapted to the buckling groove of the buckling member.

[0017] A drainage pipe connected to the bottom of the limiting groove is provided inwardly on one side of the counterweight block, and a corresponding drainage valve is fixed on the drainage pipe.

[0018] A corresponding water guide groove is arranged in the middle part of the hook fastener, and a corresponding drainage notch is arranged in the buckling groove of the buckling member at a position corresponding to the water guide groove. After the hook fastener part is buckled into the buckling groove of the buckling member, the water inlet end of the water guide groove is connected to the drainage notch, and the water outlet end of the water guide groove is connected to the limiting groove of the counterweight block.

[0019] The fasteners and plate-shaped fixings are both made of engineering plastics; the counterweight block and hook fastener are made of metal materials, and the hook fastener is fixedly connected to the limiting groove of the counterweight block by welding. The limiting groove of the counterweight block and the outer surface of the hook fastener are respectively coated with a corresponding anti-rust paint layer.

[0020] The limiting holes are respectively fixed with corresponding metal buckles, and the locking mechanism includes a countersunk screw and a countersunk rivet nut, through which the upper parts of the first locking clamp and the second locking clamp are effectively locked and installed.

[0021] Advantages of the present invention:

[0022] 1) The tarpaulin clamp of the present invention comprises a first locking clamp and a second locking clamp which are correspondingly arranged. During the clamping process: first, the front end of the rainproof tarpaulin is folded in half and passed through the first locking clamp, the second locking clamp and the roof panel spine; then, the limiting holes of the rainproof tarpaulin are respectively buckled to the clamping protrusions of the first locking clamp and the second locking clamp; then, the first locking clamp and the second locking clamp are locked by the locking mechanism, so that the clamping protrusions of the first locking clamp and the second locking clamp are effectively clamped to the roof panel spine, thereby achieving a firm fixation of the rainproof tarpaulin.

[0023] On this basis, the present invention further has a buffer rubber block fixed in an extruded state between the middle parts of the first locking clamp and the second locking clamp, the bottom of the buffer rubber block abuts against the top of the roof panel spine, and the upper side of the folded portion of the rainproof tarpaulin is clamped between the buffer rubber block and the first locking clamp and the second locking clamp. Through the intervention of the buffer rubber block arranged in an extruded state, on the one hand, the fixing surface of the rainproof tarpaulin can be increased, and a larger area of ​​friction can be formed on it, thereby improving the fixing effect of the rainproof tarpaulin; on the other hand, it can effectively form an obvious buffering limit on the top of the roof panel spine. When the clamping protrusions of the first locking clamp and the second locking clamp form a large stress concentration with the top of the roof panel spine, the two sides of the roof panel spine will be forced to compress and deform inward, thereby causing the top of the roof panel spine to deform upward. At this time, under the buffering and tightening of the buffer rubber block, the deformation space at the top of the roof panel spine can be effectively limited, thereby preventing the roof panel spine from producing obvious compression deformation. Thereby, the clamping stability between the tarpaulin clamp and the roof panel ridge can be greatly improved, so as to further improve the fixing effect of the rainproof tarpaulin.

[0024] 2) The counterweight block of the present invention has a plate-shaped hook fastener fixedly connected obliquely upward in the middle, and the fastener of the fixing device at the rear end of the rainproof tarpaulin is fastened to the hook fastener, so that the rainproof tarpaulin is set in a tensioned state. The rear end of the rainproof tarpaulin is fixed by the hook fastener set in the middle of the counterweight block, so that when the rainproof tarpaulin is swung upward by the wind, the rainproof tarpaulin is pulled down to prevent the counterweight block from being "turned over" with one end as the fulcrum, thereby improving the fixing effect of the rear end of the rainproof tarpaulin without increasing the weight of the heavy object.

[0025] 3) The bottom end surface of the counterweight block of the present invention is arranged in a horizontal plane, and corresponding support rollers are rotatably mounted on both sides of the inner end of the counterweight block, and the bottom end of the support roller is arranged flush with the bottom end surface of the counterweight block, and a group of handles for moving the counterweight block are fixed outwardly at the outer end of the counterweight block. During the movement of the counterweight block, the counterweight block can be flipped upward by the handle for moving the counterweight block, so that the counterweight object can be moved with the support rollers as the rolling fulcrum, thereby realizing the movement and use of the counterweight block without the intervention of lifting equipment, thereby greatly improving the practical effect of the present invention.

[0026] 4) The upper surface of the fastener of the present invention is laterally provided with a corresponding fastening groove, and the top of the hook fastener is folded inward in an inverted L shape and provided with a hook fastener portion that matches the fastening groove of the fastener, thereby ensuring the fixing effect on the fastener, that is, the rear end of the rainproof tarpaulin. Among them, the middle part of the counterweight block is concavely provided with a corresponding limiting groove, and the hook fastener is fixedly connected to the limiting groove of the counterweight block, thereby reducing the deadweight of the counterweight block to further improve its mobility. After the counterweight block is fixed in place, water can be added to the limiting groove of the counterweight block by means of water injection to lift the counterweight, thereby improving the mobility of the counterweight block while effectively ensuring the fixing effect on the rainproof tarpaulin.

[0027] 5) Through the design of the structure of the counterweight block, the present invention can also effectively and significantly improve the convenience of the tensioning and fixing operation of the rainproof tarpaulin. When the original counterweight is used to fix the rainproof tarpaulin, it is necessary to manually tension the rear end of the rainproof tarpaulin, and then hoist the counterweight into place through the hoisting equipment. In the process of tightening the counterweight, the problem of over-tightening the rainproof tarpaulin or insufficient tightening often occurs. In the former, the tensioning force of the rainproof tarpaulin is too large, resulting in excessive pressure on the unfinished metal roof structure layer, thereby destroying its structural stability; in the latter, the tensioning force of the rainproof tarpaulin is insufficient, resulting in the rainproof tarpaulin being easily affected by the wind and causing it to drift and shake, which will also damage the unfinished metal roof structure layer. Therefore, after each storm, before resuming the construction of the metal roof, the damaged metal roof structure layers need to be repaired, which is very troublesome.

[0028] During use of the present application, the counterweight block can be flipped up in advance by using the handle for moving the counterweight block, so that it uses the supporting roller as a rolling fulcrum, and then the counterweight block is moved to the rear end close to the rainproof tarpaulin, and the hook portion of the hook fastener is fastened to the fastening groove of the fastener; thereafter, the counterweight block is driven to move backward, so that the rainproof tarpaulin is gradually set in a tensioned state; after the rainproof tarpaulin is tensioned in place, the connection between the hook fastener and the fastener is used as a pulling and fixing end, so that the counterweight block uses the supporting roller as a rolling fulcrum to produce a downward swing until the bottom surface of the counterweight block is attached to the bottom surface. The entire tensioning operation process of the rainproof tarpaulin is not only extremely convenient, but also can ensure that the tensioned rainproof tarpaulin can form a more reasonable covering pressure on the unfinished metal roof structure layer, thereby further greatly improving the practical effect of the present invention.

[0029] 6) A water guide groove is provided in the middle of the hook fastener of the present invention, and a corresponding drainage notch is provided in the buckling groove of the buckle member at a position corresponding to the water guide groove. After the hook fastener portion of the hook fastener is buckled to the buckling groove of the buckle member, the water inlet end of the water guide groove is connected to the drainage notch, and the water outlet end of the water guide groove is connected to the limiting groove of the counterweight block. On rainy days, rainwater is guided along the rainproof tarpaulin into the water guide groove, and then guided along the water guide notch of the water guide groove into the limiting groove. During use, it is only necessary to connect the drainage pipe connected to the counterweight block to an external rainwater collection area or a rainwater recycling collection pool through a corresponding drainage pipeline and a water pump, and then open the drainage valve and start the water pump to divert and collect the rainwater guided by the rainproof tarpaulin, thereby preventing the rainwater from being concentratedly discharged to the construction site due to the intervention of the rainproof tarpaulin, so as to prevent damage to the construction site.
