Description

Technical Field

[0001] The present invention relates to the technical field of installation of water stop steel plates, and particularly relates to a temporary fixator for water stop steel plates. Background Art

[0002] Water stop steel plates are widely used at the construction joints between new and old concrete pouring sections, and their installation positions need to be located at the exact center of the construction joint to exert their best waterproof efficiency. During construction, the water stop steel plates are installed in the steel bar structure, and the central positioning of the water stop steel plates mainly relies on on-site measurement and setting out by construction workers and adjustment by visual inspection. However, due to complex construction environments (such as light and space limitations), errors of measuring tools, and inevitable visual errors, it is very easy for the water stop steel plates to deviate from the designed center line.

[0003] In addition, since the length of a single water stop steel plate is limited, multiple steel plates need to be welded end to end to form a continuous water stop belt in actual construction. Before the completion of construction, due to the lack of effective temporary fixing and support at each position of the water stop belt, the water stop steel plates in this "cantilever" state will still deviate from the designed center line. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a temporary fixator for water stop steel plates to solve the problem that the water stop steel plates in the prior art deviate from the designed center line.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A temporary fixator for water stop steel plates, comprising:

[0008] A first positioning structure, including a first positioning rod, which is arranged on the installation seat and used to abut against the outer surface of the water stop steel plate;

[0009] A second positioning structure, including a second positioning rod and a driving rod, one end of the second positioning rod and one end of the driving rod are both movably arranged in the installation cavity, and the other ends of both extend along the first open end and the second open end respectively. Under the action of an external force, the driving rod can drive the second positioning rod to form a locked state and an unlocked state. In the locked state, the second positioning rod presses against the upper surface of the water stop steel plate, and in the unlocked state, the second positioning rod is spaced from the water stop steel plate;

[0010] And

[0011] The limiting structure includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are respectively arranged on the mounting seat and the driving rod, and the two are detachably connected, so as to switch the second positioning rod between the locked state and the unlocked state through the driving rod.

[0012] Furthermore, the second positioning rod includes:

[0013] A hanging portion protruding outside the first open end for pressing against the upper surface of the water stop steel plate;

[0014] A connecting portion extending towards the direction of the second open end for connecting the hanging portion and the driving rod;

[0015] A matching portion arranged at the connection of the hanging portion and the connecting portion and abutting against or separating from the mounting seat;

[0016] Wherein, a positioning groove is provided at the connection of the hanging portion and the connecting portion, and a positioning shaft passes through the positioning groove and is fixed to the mounting seat, so that when switching between the locked state and the unlocked state, the second positioning rod moves relative to the positioning shaft.

[0017] Furthermore, a spring is provided on the mounting seat from the first open end towards the direction of the second open end for connecting the matching portion.

[0018] Furthermore, the first positioning rod is provided with a convex platform, and a groove is formed between the convex platform and the mounting seat, and the matching portion is located in the groove.

[0019] Furthermore, the driving rod is slidably arranged in the installation cavity, and its sliding direction is arranged along the open direction of the installation cavity.

[0020] Furthermore, the driving rod is provided with a guide groove, a first inclined surface is formed at one end of the driving rod located in the installation cavity, the connecting portion is provided with a protrusion, a second inclined surface is formed at one end of the protrusion close to the hanging portion, the protrusion is located in the guide groove, and the first inclined surface and the second inclined surface are slidably attached.

[0021] Furthermore, both the first limiting member and the second limiting member are provided with threaded holes for a locking bolt to pass through.

[0022] Furthermore, arc-shaped avoidance openings are provided on the opposite end faces of the first limiting member and the second limiting member.

[0023] Furthermore, the first positioning rod and the mounting seat are integrally formed.

[0024] Furthermore, the first positioning rod and the mounting seat are detachably connected, and scale lines are provided thereon.

[0025] Compared with the prior art, the present invention has the following beneficial effects: The first positioning rod can abut against the outer surface of the water stop steel plate, making it form a standard reference point, so as to control the water stop steel plate at the design center line by using the length of the first positioning rod; at the same time, under the action of an external force, the driving rod can drive the second positioning rod to form a locked state and an unlocked state, so as to press or release the upper surface of the water stop steel plate. Combining with the first positioning rod can achieve the purpose of fixing the water stop steel plate at the design center line, and can quickly release the water stop steel plate after the construction is completed; furthermore, the first limiting member and the second limiting member can not only play a role in switching the two states of the second positioning rod, but also fix the whole fixture in the steel bar structure, so as to control the switching of the second positioning rod between the locked state and the unlocked state by using their separable connection method. The installation of the fixture and the positioning of the water stop steel plate can be completed in one operation, which can play a role in temporarily supporting and positioning the water stop steel plate and ensure that it can always be at the design center line.

[0041] The present invention will be further described in detail below through specific implementation manners:

[0042] In the embodiment of the present invention, as Figures 1 - 5 shown, the temporary fixer for the waterstop steel plate includes: a mounting base 1, a first positioning structure, a second positioning structure, and a limiting structure; the mounting base 1 is provided with a mounting cavity that is closed on all sides and open at opposite ends, and the two open ends of the mounting cavity are defined as a first open end 101 and a second open end 102 respectively; the first positioning structure includes a first positioning rod 2, and the first positioning rod 2 is arranged on the mounting base 1 for abutting against the outer surface of the waterstop steel plate; the second positioning structure includes a second positioning rod 3 and a driving rod 4, one end of the second positioning rod 3 and one end of the driving rod 4 are both movably arranged in the mounting cavity, and the other ends of the two extend along the first open end 101 and the second open end 102 respectively. Under the action of an external force, the driving rod 4 can drive the second positioning rod 3 to form a locked state and an unlocked state. In the locked state, the second positioning rod 3 presses against the upper surface of the waterstop steel plate, and in the unlocked state, the second positioning rod 3 is spaced from the waterstop steel plate; the limiting structure includes a first limiting member 5 and a second limiting member 6, the first limiting member 5 and the second limiting member 6 are respectively arranged on the mounting base 1 and the driving rod 4, and the two are detachably connected, so as to switch the second positioning rod 3 between the locked state and the unlocked state through the driving rod 4.

[0043] Specifically, in the embodiment of the present invention, the mounting base 1 forms a mounting cavity that is closed on all sides and open at opposite ends. The mounting cavity has a first open end 101 and a second open end 102, so that the first open end 101 and the second open end 102 are arranged in the left-right direction. The first positioning rod 2 is installed at the mounting base 1 and is located below the first open end 101 for abutting against the outer surface (i.e., the side surface) of the waterstop steel plate. Thus, the position of the waterstop steel plate in the steel bar structure is controlled by the length of the first positioning rod 2 itself, preventing the waterstop steel plate from moving towards the direction of the first positioning rod 2, and providing preliminary positioning and a supporting force on one side, so that it can be used as a standard reference point to ensure that the waterstop steel plate is always at the design center line.

[0044] In the embodiment of the present invention, a second positioning rod 3 and a driving rod 4 are respectively arranged at the first open end 101 and the second open end 102, and both are movably arranged in the installation cavity. When an external force acts on the driving rod 4, the driving rod 4 can drive the second positioning rod 3 to move, so that the second positioning rod 3 has a locked state and an unlocked state; in the locked state, the second positioning rod 3 can press the upper surface of the water stop steel plate, and cooperate with the first positioning rod 2 to fix the water stop steel plate at the design center line; in the unlocked state, the second positioning rod 3 and the water stop steel plate are independently arranged, and the water stop steel plate can be quickly released after the construction of the water stop steel plate is completed, so as to be reused. That is, the external force applied to the driving rod 4 will compulsorily drive the second positioning rod 3 to generate corresponding movement; when the driving rod 4 is operated to a specific position, the second positioning rod 3 can be driven to move to the locked position, and the protruding end thereof abuts against and presses the upper surface of the water stop steel plate; at this time, the second positioning rod 3 and the first positioning rod 2 jointly act to firmly clamp the water stop steel plate at the design center line to achieve fixation. When the driving rod 4 is operated to the unlocking position, the second positioning rod 3 can be driven to retract and lift, so that the protruding end thereof leaves the upper surface of the water stop steel plate to keep a certain distance therefrom; at this time, the water stop steel plate can be easily removed or moved to a new position.

[0045] In the embodiment of the present invention, the limiting structure includes a first limiting member 5 and a second limiting member 6. The two limiting members are connected in a separable manner, and the two limiting members are respectively installed on the mounting seat 1 and the driving rod 4. Since the driving rod 4 needs to move under the action of an external force, the second limiting member 6 can move relative to the first limiting member 5. Then, when the second limiting member 6 moves in the direction close to the first limiting member 5, the second positioning rod 3 will be gradually formed into a locked state through the driving member. Finally, when the two limiting members are fixedly connected, the second positioning rod 3 stops in the locked state because the second limiting member 6 no longer moves relative to the first limiting member 5. On the contrary, when the second limiting member 6 moves in the direction away from the first limiting member 5, the second positioning rod 3 can be gradually switched from the locked state to the unlocked state through the driving member until the second positioning rod 3 releases the water stop steel plate. That is, by operating the driving rod 4 or the second limiting member 6 thereon to connect or separate the two limiting members, the second positioning rod 3 can be clearly controlled to switch between the locked state and the unlocked state, providing the safety and reliability of the operation and preventing the clamping failure caused by misoperation.

[0046] In addition, in order to install this fixture at the steel bar structure, a first limiting member 5 and a second limiting member 6 are provided; after the first limiting member 5 and the second limiting member 6 are connected, they can be fixed at the steel bar structure; conversely, after the two are separated, the whole fixture can be disassembled from the steel bar structure. Thus, through the separable connection of the first limiting member 5 and the second limiting member 6, not only can this fixture be quickly installed on the steel bar structure or removed from the steel bar structure, but also the position state of the second positioning rod 3 can be dynamically adjusted through the cooperation of the first limiting member 5 and the second limiting member 6, so as to position the water stop steel plate at the design center line by using the first positioning rod 2 and the second positioning rod 3 while installing this fixture at the steel bar structure, and the operation is simple and fast.

[0047] In this embodiment, the purpose of static support and fixation is achieved by the pre-set first positioning rod 2 abutting against the side surface of the water stop steel plate; furthermore, by using the cooperation of the second positioning structure and the limiting structure, the purpose of dynamic adjustment and fixation is achieved, which can not only provide a reliable clamping force to prevent the steel plate from deviating from the center line, but also improve the installation and disassembly efficiency.

[0048] As Figures 2 - 6 shown, in an embodiment, the second positioning rod 3 includes: a hanging portion 301, a connecting portion 302 and a matching portion 303; the hanging portion 301 protrudes beyond the first open end 101 for pressing against the upper surface of the water stop steel plate; the connecting portion 302 extends towards the direction of the second open end 102 for connecting the hanging portion 301 and the driving rod 4; the matching portion 303 is arranged at the connection of the hanging portion 301 and the connecting portion 302 and abuts against or separates from the mounting seat 1; a positioning groove 304 is provided at the connection of the hanging portion 301 and the connecting portion 302, and a positioning shaft 7 passes through the positioning groove 304 and is fixed to the mounting seat 1 so that when switching between the locked state and the unlocked state, the second positioning rod 3 moves relative to the positioning shaft 7.

[0049] Specifically, in order for the second positioning rod 3 to have a pressing action and a releasing action; in this embodiment, it is defined that the second positioning rod 3 includes a hanging portion 301, a connecting portion 302, and a mating portion 303. One end of the hanging portion 301 extends into the installation cavity for connection with the connecting portion 302, and the other end extends outside the first open end 101 and forms a hook. This hook can be hung on the waterstop steel plate and can "clamp" the waterstop steel plate at the design center line under the action of the first positioning rod 2. The connecting portion 302 is located in the installation cavity for connection with the driving rod 4. The mating portion 303 is arranged between the hanging portion 301 and the connecting portion 302 and is arranged in the up-down direction. A positioning groove 304 is provided at the connection between the hanging portion 301 and the connecting portion 302. The positioning groove 304 is arranged in the left-right direction, and a positioning shaft 7 is arranged in the positioning groove 304, so that when the second positioning rod 3 switches between the locked state and the unlocked state, it can move relative to the positioning shaft 7; at the same time, the setting of the positioning groove 304 and the positioning shaft 7 can position the second positioning rod 3 and can prevent it from detaching from the mounting seat 1. And during the movement process, the mating portion 303 can abut against or separate from the mounting seat 1 to play a limiting role; thus, through the cooperation of each component, the second positioning rod 3 can move relative to the mounting seat 1 under the drive of the driving rod 4 to form a locked state or an unlocked state.

[0050] Further, as Figure 4 , Figure 5 shown, in one embodiment, from the direction of the first open end 101 to the second open end 102, the mounting seat 1 is provided with a spring 8 for connecting the mating portion 303. Specifically, in order to achieve the rapid reset of the second positioning rod 3; in this embodiment, a spring 8 is provided at the mounting seat 1. The axis of the spring 8 is arranged in the left-right direction and is connected to the mating portion 303; thus, when the second positioning rod 3 is in the unlocked state, the mating portion 303 stretches the spring 8; when the second positioning rod 3 switches from the unlocked state to the locked state, the spring 8 can rapidly drive the second positioning rod 3 to reset during the reset process. At the same time, the second positioning rod 3 can be kept in the locked state when the fixing device is not in use, so that the distance between the first limiting member 5 and the second limiting member 6 will not be too large to affect storage.

[0051] Further, as Figure 2 , Figure 5As shown, in one embodiment, the first positioning rod 2 is provided with a boss 201. A groove 103 is formed between the boss 201 and the mounting base 1, and the engaging portion 303 is located within the groove 103. Specifically, in order to further limit the engaging portion 303; in this embodiment, a boss 201 is provided on the first positioning rod 2. The boss 201 is spaced from the end face of the mounting base 1, and a groove 103 is formed therebetween, enabling the engaging portion 303 to be placed within the groove 103. At the same time, the setting of the boss 201 can increase the contact area between the first positioning rod 2 and the water stop steel plate.

[0052] As Figure 5 shown, in one embodiment, the driving rod 4 is slidably disposed within the mounting cavity, and its sliding direction is set along the open direction of the mounting cavity. Specifically, on the one hand, in order to enable the second positioning rod 3 to quickly switch between the locked state and the unlocked state, and on the other hand, it can also enable the first limiting member 5 and the second limiting member 6 to quickly separate or connect; in this embodiment, it is defined that the driving rod 4 can slide in the left-right direction, so as to fix this fixator at the steel bar structure through the reciprocating sliding of the driving rod 4, and use the first positioning rod 2 and the second positioning rod 3 to position the water stop steel plate at the center line; at the same time, the quick installation or quick disassembly of this fixator can also be realized.

[0053] Furthermore, as Figures 4 - 6 shown, in one embodiment, the driving rod 4 is provided with a guide groove 401. The guide groove 401 forms a first inclined surface 402 at one end of the driving rod 4 located within the mounting cavity. The connecting portion 302 is provided with a protrusion 305. The protrusion 305 forms a second inclined surface 306 at one end of the connecting portion 302 close to the hanging portion 301. The protrusion 305 is located within the guide groove 401, and the first inclined surface 402 is in sliding fit with the second inclined surface 306. Specifically, in order to realize the linkage mechanism between the second positioning rod 3 and the driving rod 4; in this embodiment, a linkage structure is provided. This linkage structure includes a cooperating guide groove 401 and protrusion 305, as well as a cooperating first inclined surface 402 and second inclined surface 306. The above-mentioned guide groove 401 and protrusion 305 are respectively provided at the connecting portion 302 of the driving rod 4 and the second positioning rod 3, and the first inclined surface 402 and the second inclined surface 306 are respectively located at the driving rod 4 and the connecting portion 302; thus, when the driving rod 4 slides left and right, the first inclined surface 402 can be in sliding fit with the second inclined surface 306 to change the position of the protrusion 305 within the guide groove 401, so as to be able to switch the second positioning rod 3 between the locked state and the unlocked state under the cooperation of the above-mentioned structure.

[0054] As Figures 2 - 6As shown, in one embodiment, the first limiting member 5 and the second limiting member 6 are both provided with threaded holes 601 for the locking bolts 602 to pass through. Specifically, in order to achieve the separable connection between the first limiting member 5 and the second limiting member 6, in this embodiment, a threaded hole 601 is provided at each of the first limiting member 5 and the second limiting member 6. The first limiting member 5 and the second limiting member 6 are independently arranged. When it is necessary to connect the two limiting members, the locking bolt 602 is used to pass through the threaded hole 601.

[0055] Further, as Figure 2 , Figure 5 , Figure 6 shown, in one embodiment, the opposite end faces of the first limiting member 5 and the second limiting member 6 are both provided with arc-shaped relief openings 603. Specifically, since the first limiting member 5 and the second limiting member 6 need to be fixed to the steel bar structure, in this embodiment, in order to adapt to the surface of the steel bar, arc-shaped relief openings 603 are provided at the opposite end faces of the first limiting member 5 and the second limiting member 6. The two relief openings 603 can cover the surface of the steel bar to increase the contact area with the steel bar, so as to firmly fix this fixator to the steel bar structure.

[0056] In one embodiment, the first positioning rod 2 and the mounting seat 1 are integrally formed. The length of the first positioning rod 2 is constant to avoid inaccurate positioning dimensions caused by randomly changing the position of the first positioning rod 2. Of course, in the embodiment, since the distances between the center lines are not unique, in order to improve the versatility of this fixator, the first positioning rod 2 and the mounting seat 1 are detachably connected and are provided with scale lines thereon. By replacing the first positioning rod 2 with a corresponding size, and in order to ensure the self-precision of the first positioning rod 2, scale lines need to be provided thereon for measuring the distance between the center lines.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
