Abstract
Description
Technical Field
[0001] The utility model relates to the field of pile foundation construction devices, in particular to a rainproof device used for welding prefabricated pipe piles. Background Art
[0002] At present, prefabricated pipe piles are widely welcomed by construction projects for their fast construction speed and excellent bearing capacity. Prefabricated pipe piles enter the soil layer by static pressure and hammering. When the prefabricated pipe piles are not long enough, they usually need to be connected. At present, the connection method between prefabricated pipe piles is mainly welding. The welding quality of the pipe pile connection must be guaranteed before entering the soil, and subsequent processes can only be carried out after passing the inspection.
[0003] However, due to the particularity of the installation process of prefabricated pipe piles, it is impossible to weld the two sections of prefabricated pipe piles in advance before pressing them into the soil layer. Therefore, the pile connection operations are basically carried out on-site in the open air. The welding operation time is greatly affected by the weather. Once it rains, welding construction is basically impossible. Even light rain will affect the construction quality. The quality of the weld cannot be guaranteed, so the welding qualification rate is affected, and the quality of the pile body cannot be guaranteed. On the one hand, it will greatly delay the construction progress, and on the other hand, the rework of unqualified welds will further lose construction time.
[0004] There is also a rainproof device for welding construction work in light rain in the prior art. The device is generally installed by construction workers on the construction site. An umbrella-shaped shield is installed on the prefabricated pipe pile to prevent rain from directly falling on the welding points of the prefabricated pipe pile. This device is directly fixed by a clamp. In order to ensure a tight and stable connection and avoid water seepage, a large clamping force needs to be applied, which is easy to damage the prefabricated pile body structure and affect the mechanical properties of the prefabricated pipe pile body.
[0005] Therefore, a rainproof device for prefabricated pipe pile welding is proposed to solve the above technical problems. Utility Model Content
[0006] The technical problem solved by the utility model lies in the welding work in the existing prefabricated pipe pile construction process. In order to connect tightly and avoid leakage, the existing prefabricated pipe pile rainproof welding device needs to apply a large clamping force, which can easily cause damage to the pile body structure and affect the mechanical properties of the prefabricated pipe pile body.
[0007] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows:
[0008] A rainproof device for welding prefabricated pipe piles, comprising a cylinder body clamped on the outside of the prefabricated pipe pile, the cylinder body comprising a left cylinder body and a right cylinder body, the left cylinder body and the right cylinder body are provided with connecting wing plates extending radially outwardly along the cylinder body at the joint, and the cylinder body is locked above the prefabricated pipe pile to be welded by tension bolts on the connecting wing plates;
[0009] It also includes a rain shield plate that is clamped on the outside of the cylinder, the rain shield plate is in the shape of an inverted funnel, and the rain shield plate is also divided into a left plate and a right plate. The top of the rain shield plate is provided with a connecting ring that extends upward along the outer surface of the cylinder, and the connecting ring and the outer wall of the cylinder are provided with mutually matching bolt holes. The rain shield plate is connected to the cylinder through the mounting bolts and the bolt holes; the projection range of the rain shield plate covers the entire cylinder range, and an operating space is extended outward;
[0010] It also includes a rubber cushion layer which is arranged on the inner wall of the cylinder and is closely attached to the prefabricated pipe pile body.
[0011] Particularly, a water storage tank is provided at the bottom of the rain shield, and a downwardly inclined drainage pipe is provided at the bottom of the water storage tank.
[0012] Furthermore, the bottom of the water storage tank has a slope, and the drainage pipe is arranged at the lowest point.
[0013] Particularly, the left plate and the right plate are respectively provided with a connecting protrusion and a connecting groove covering the outside of the connecting protrusion at the joint, and a sealing strip is also provided on the outside of the connecting protrusion.
[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects: the utility model has a simple structure and is easy to use. The rain shield effectively blocks external rainwater. The utility model is firmly installed on the prefabricated pipe pile through the cylinder, which effectively increases the contact area between the rain shield and the prefabricated pipe pile, reduces the pressure on the unit area of the prefabricated pipe pile, and ensures the integrity of the prefabricated pipe pile body structure. The existence of the connecting ring can also prevent the clamp from being directly clamped on the prefabricated pipe pile body, further preventing the prefabricated pipe pile body from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the structure of the device of the utility model.
[0016] The meanings of the numbers in the figure are: cylinder body—1; connecting wing plate—2; rain shield—3; connecting ring—4; bolt hole—5; water storage tank—6; drainage pipe—7. DETAILED DESCRIPTION
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0018] like Figure 1As shown, a rainproof device for welding prefabricated pipe piles comprises a cylinder 1 clamped on the outside of the prefabricated pipe pile, the cylinder 1 comprises a left cylinder and a right cylinder, the left cylinder and the right cylinder are provided with a connecting wing plate 2 extending radially outward along the cylinder 1 at the joint, and the cylinder 1 is locked above the prefabricated pipe pile to be welded by the tension bolts on the connecting wing plate 2;
[0019] It also includes a rain shield 3 that is clamped on the outside of the cylinder 1. The rain shield 3 is in the shape of an inverted funnel. The rain shield 3 is also divided into a left plate and a right plate. The top of the rain shield 3 is provided with a connecting ring 4 that extends upward along the outer surface of the cylinder 1. The connecting ring 4 and the outer wall of the cylinder 1 are provided with mutually matching bolt holes 5. The rain shield 3 is connected to the cylinder 1 through the mounting bolts and the bolt holes 5. The projection range of the rain shield 3 covers the entire range of the cylinder 1, and an operating space extends outward;
[0020] It also includes a rubber cushion layer which is arranged on the inner wall of the cylinder 1 and is in close contact with the prefabricated pipe pile body.
[0021] In the utility model, the main principle is: by clamping the cylinder 1 above the part to be welded of the prefabricated pipe pile, an installation position is provided for the entire utility model device, and by setting a connecting wing plate 2 at the joint of the left cylinder and the right cylinder and tightening the connecting wing plate 2 by means of tension bolts, damage to the pile body structure of the prefabricated pipe pile can be effectively avoided. At the same time, since the cylinder 1 itself has a certain height, the pressure per unit area of the prefabricated pipe pile body can be effectively reduced, that is, the pressure of the prefabricated pipe pile body receiving the cylinder 1 can be reduced, thereby avoiding the situation of damage to the pile body structure. In addition, since the inner wall of the cylinder 1 is also provided with a rubber cushion layer that fits the pile body of the prefabricated pipe pile, the pressure on the prefabricated pipe pile can be further buffered to further ensure the integrity of the pile body structure. At the same time, the rubber cushion layer can also effectively fill the tiny gap between the cylinder 1 and the pile body, thereby effectively avoiding the problem of the welding point being affected by the penetration of rainwater along the gap. Since the cylinder 1 itself has a certain height, a sufficiently long rubber cushion layer can also be set in the cylinder 1 to avoid the problem of rainwater penetration due to the small overall height of the rubber cushion layer. The area of the rain shield 3 is larger than that of the cylinder 1 and extends outward to provide operating space, thereby providing sufficient construction positions to prevent construction workers and welding equipment from being wetted by rain. When welding, workers can quickly and conveniently perform construction on the welding points below the cylinder 1 by standing within the range of the rain shield 3.
[0022] As a preferred embodiment, a water storage tank 6 is further provided at the bottom of the rain shield 3 , and a downwardly inclined drainage pipe 7 is further provided at the bottom of the water storage tank 6 .
[0023] In this embodiment, by providing a water storage tank 6 and a drainage pipe 7, the stored water is discharged in a unified manner, thereby further ensuring the dryness of the space below the rain shield 3 and avoiding splashing of rainwater.
[0024] As a further embodiment, the bottom of the water storage tank 6 has a slope, and the drainage pipe 7 is arranged at the lowest point.
[0025] In this embodiment, the bottom of the water storage tank 6 is configured to have a sloped bottom so that water can flow directionally along the bottom of the water storage tank 6 when there is not much water stored, thereby facilitating the discharge of the water stored in the water storage tank 6.
[0026] As a preferred embodiment, the left plate and the right plate are respectively provided with a connecting protrusion and a connecting groove covering the outside of the connecting protrusion at the joint, and a sealing strip is also provided on the outside of the connecting protrusion.
[0027] In this embodiment, connecting grooves and connecting protrusions are provided at the joints of the left plate and the right plate to reduce the probability of rainwater seeping in from the joints, and sealing strips are used to seal the joints between the connecting grooves and the connecting protrusions to further prevent rainwater leakage.
