Description

Technical Field

[0001] The invention relates to the technical field of dam construction, in particular to a prefabricated non-disassembly template for a dam corbel. Background Art

[0002] The role of the prefabricated formwork for the dam corbel is to achieve a fast, safe and efficient construction process by pre-manufacturing and optimizing the formwork structure. This formwork design eliminates the formwork removal step in traditional construction, greatly reducing safety hazards in construction, while improving construction efficiency and the appearance quality of the structure, ensuring the stability and bearing capacity of the dam corbel part.

[0003] However, after the formwork is installed, the speed of pouring concrete cannot be precisely controlled, resulting in the impact force generated when the concrete falls at a faster speed, which will produce significant lateral pressure on the back of the formwork. This pressure exceeds the bearing capacity of the fixed formwork and will cause the formwork connection to loosen, causing the formwork to shift, which in turn leads to defects such as unevenness, honeycombs or voids on the concrete surface, reducing the density and durability of the dam structure and increasing the risk of dam damage.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a prefabricated non-disassembly formwork for a dam corbel. By setting a limiting component 100 and a supporting component 200, it is prevented that the pressure of liquid concrete on the plate body 104 causes the loosening of the connection between the plate body 104 and the second embedded steel bar 105, and prevents the plate body 104 from being displaced to cause defects such as unevenness, honeycombs or voids on the concrete surface, thereby preventing the density and durability of the dam structure from being reduced and the risk of increasing dam damage is avoided.

[0030] Specifically, the limiting assembly 100 includes a first embedded steel bar 101, a support frame 102 arranged on the first embedded steel bar 101, a stabilizing rod 103 arranged on the inner wall of the end of the support frame 102, a plate body 104 arranged on one side of the support frame 102 and a second embedded steel bar 105 arranged at the bottom of the plate body 104; and a supporting assembly 200 includes a tensioning member 201, a supporting member 202 arranged on the tensioning member 201 and a knocking member 203 arranged between the tensioning member 201 and the plate body 104; wherein the supporting assembly 200 is arranged on the limiting assembly 100; wherein the tensioning member 201 includes a mud receiving plate 201a, and the space on one side of the plate body 104 close to the supporting assembly 200 is poured with concrete, and the concrete exerts pressure on the plate body 104, and the concrete falls on the mud receiving plate 201a to deflect the mud receiving plate 201a, thereby pulling the knocking member 203 to make the plate body 104 generate a force opposite to the concrete.

[0031] The first embedded steel bar 101 and the second embedded steel bar 105 are inserted and fixedly sleeved into the poured concrete to limit the position, and the stabilizing rod 103 can strengthen the structural strength of the support frame 102 and increase the stability.

[0032] In summary, by setting the limiting component 100 and the supporting component 200, when the workers pre-embed the first embedded steel bar 101 and the second embedded steel bar 105 into the poured concrete layer, and then install the plate body 104 on the second embedded steel bar 105 at a pre-designed inclination angle, the stabilizing rod 103 is fixedly connected to the support frame 102, and the support frame 102 is respectively fixedly connected to the plate body 104 and the first embedded steel bar 101, the tensioning member 201 is fixedly connected to the first embedded steel bar 101 and installed in the poured concrete, the supporting member 202 is fixedly connected to the supporting frame 102 and the stabilizing rod 103 and the bottom end of the supporting member 202 is installed in the poured concrete, and a row is installed reciprocatingly, and the plate bodies 104 are tightly attached to each other without any gaps.

[0033] When workers pour liquid and viscous concrete in the space on one side of the plate body 104 close to the supporting assembly 200, the concrete falls on the side of the plate body 104 close to the supporting assembly 200. Part of the concrete exerts downward pressure on the side under the action of gravity, causing the plate body 104 to tend to deflect downward, increasing the loosening probability of the connection between the plate body 104 and the second embedded steel bar 105, while the remaining part of the concrete is poured on the tensioning member 201, so that the tensioning force exerted by the tensioning member 201 on the plate body 104 by pulling the striking member 203 and the pressure exerted by the concrete on the plate body 104 are partially offset, reducing the loosening probability of the connection between the plate body 104 and the second embedded steel bar 105. rate, and the tensioning member 201 will press against the supporting member 202 to deflect the supporting member 202, so that the end of the supporting member 202 applies a thrust to the plate body 104, and this thrust further offsets the pressure exerted by the concrete on the plate body 104, further reduces the probability of loosening at the connection between the plate body 104 and the second embedded steel bar 105, avoids the pressure of the liquid concrete on the plate body 104 causing the connection between the plate body 104 and the second embedded steel bar 105 to loosen, prevents the plate body 104 from being displaced and causing defects such as unevenness, honeycombs or voids on the concrete surface, thereby preventing the density and durability of the dam structure from being reduced, and avoiding the risk of increasing dam damage.

[0034] Example 2

[0035] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that a tensioning member 201 and a supporting member 202 are provided. The advantage of such a provision is to prevent the pressure of liquid concrete on the plate body 104 from causing loosening of the connection between the plate body 104 and the second embedded steel bar 105, and to prevent the plate body 104 from being displaced and causing defects such as unevenness, honeycombs or voids on the concrete surface, thereby preventing the density and durability of the dam structure from being reduced and the risk of increasing dam damage.

[0036] Specifically, the mud receiving plate 201a is arc-shaped and both ends of the mud receiving plate 201a are bent in a direction away from the ground, and a receiving groove 201b is provided on one side of the mud receiving plate 201a away from the ground.

[0037] An anti-slip groove is provided at the top of the mud receiving plate 201a, and the first bearing rod 201c is rotatably connected to both sides of the mud receiving plate 201a. The bottom end of the first bearing rod 201c is fixedly connected to the first embedded steel bar 101 and inserted into the poured concrete. The weight of the part from the bottom end of the mud receiving plate 201a to the first bearing rod 201c is lighter than the weight of the part from the top end of the mud receiving plate 201a to the first bearing rod 201c.

[0038] The supporting member 202 includes two second bearing rods 202a fixedly connected to the supporting frame 102 and the stabilizing rod 103. The bottom ends of the second bearing rods 202a are inserted into the poured concrete. The same blocking rod 202b is provided on the side where the two second bearing rods 202a are close to each other.

[0039] The two second bearing rods 202a are rotatably connected to one side thereof close to each other with a counterweight 202d. The center of gravity of the counterweight 202d is located at one end of the second bearing rod 202a away from the plate 104.

[0040] The same second connecting block 202h is arranged on the side where the two counterweight blocks 202d are close to each other, and a resistance groove 202c is opened at the bottom of the second connecting block 202h. Under normal conditions, the vertical projection area of ​​the second connecting block 202h is larger than the vertical projection area of ​​the mud plate 201a from the first bearing rod 201c to the top.

[0041] A connecting rod 202e is disposed at one end of the counterweight block 202d close to the plate body 104, and an arc-shaped abutting rod 202f is disposed at one end of the connecting rod 202e away from the connecting rod 202e.

[0042] The same first connection block 202g is disposed on the side where the two arc-shaped abutting rods 202f are close to each other. The end of the arc-shaped abutting rod 202f is arc-shaped. The end of the connecting rod 202e close to the arc-shaped abutting rod 202f is inclined in a direction away from the plate body 104.

[0043] The sum of the weights of the counterweight block 202d and the second connecting block 202h is greater than the sum of the weights of the connecting rod 202e, the arc-shaped abutting rod 202f and the first connecting block 202g.

[0044] Among them, the mud receiving plate 201a is arc-shaped and both ends of the mud receiving plate 201a are bent away from the ground, so that the end of the mud receiving plate 201a close to the counterweight block 202d can push and resist the counterweight block 202d when the mud receiving plate 201a is deflected, so that the end of the mud receiving plate 201a away from the counterweight block 202d can receive the concrete poured from above.

[0045] A receiving groove 201b is provided on one side of the mud receiving plate 201a away from the ground, and the receiving groove 201b is conducive to catching concrete poured from above into the receiving groove 201b to prevent it from falling from the mud receiving plate 201a.

[0046] The top of the mud receiving plate 201a is provided with an anti-skid groove, which is beneficial for the end of the mud receiving plate 201a close to the counterweight block 202d to push and resist the counterweight block 202d when the mud receiving plate 201a deflects to increase the friction force and avoid slipping.

[0047] Both sides of the mud receiving plate 201a are rotatably connected with the first bearing rod 201c, which can bear the weight of the mud receiving plate 201a to prevent the gravity of the mud receiving plate 201a from being applied to the support frame 102 and the plate body 104, thereby increasing the burden on the support frame 102 and the plate body 104.

[0048] The weight of the part from the bottom end of the mud receiving plate 201a to the first bearing rod 201c is lighter than the weight of the part from the top end of the mud receiving plate 201a to the first bearing rod 201c, which makes it easier for the end of the mud receiving plate 201a away from the counterweight block 202d to tilt upward, thereby catching the poured concrete.

[0049] The supporting member 202 includes two second bearing rods 202a fixedly connected to the supporting frame 102 and the stabilizing rod 103, so as to bear the gravity of the counterweight block 202d, the second connecting block 202h, the connecting rod 202e, the arc-shaped resistance rod 202f and the first connecting block 202g, thereby preventing an additional burden on the plate body 104 and the supporting frame 102.

[0050] An interference groove 202c is provided at the bottom of the second connecting block 202h to facilitate the interference of the end of the mud receiving plate 201a. Under normal circumstances, the vertical projection area of ​​the second connecting block 202h is larger than the vertical projection area of ​​the mud receiving plate 201a from the first bearing rod 201c to the top end, so as to prevent workers from pouring concrete at the end of the mud receiving plate 201a close to the counterweight block 202d when pouring concrete, and prevent the end of the mud receiving plate 201a away from the counterweight block 202d from being unable to deflect downward.

[0051] A first connecting block 202g is disposed on one side of the two arc-shaped abutting rods 202f that are close to each other. The first connecting block 202g can enhance the structural strength of the arc-shaped abutting rods 202f.

[0052] The end of the arc-shaped abutting rod 202 f is arc-shaped, which improves the tolerance of the arc-shaped abutting rod 202 f abutting and pressing the plate body 104 .

[0053] One end of the connecting rod 202e close to the arc-shaped abutting rod 202f is inclined away from the plate body 104 to prevent concrete from falling on the connecting rod 202e when poured, sliding through the connecting rod 202e to the side of the plate body 104 away from the connecting rod 202e and falling on people.

[0054] The sum of the weights of the counterweight block 202d and the second connecting block 202h is greater than the sum of the weights of the connecting rod 202e, the arc-shaped abutment rod 202f and the first connecting block 202g, which is beneficial for the counterweight block 202d and the second connecting block 202h to push the end of the mud plate 201a close to the counterweight block 202d to abut against the stop rod 202b to limit the position under normal conditions.

[0055] In summary, by setting the tensioning member 201 and the supporting member 202, after the workers pour the concrete, part of the concrete falls into the receiving groove 201b, so that the weight of the end of the mud receiving plate 201a away from the counterweight block 202d is greater than the sum of the weight of the end of the mud receiving plate 201a close to the counterweight block 202d, the counterweight block 202d and the second connecting block 202h, thereby causing the mud receiving plate 201a to deflect, and the end of the mud receiving plate 201a away from the counterweight block 202d sinks, and the end of the mud receiving plate 201a close to the counterweight block 202d is tilted and inserted into the resistance groove 202c to push the counterweight block 202d and the second connecting block 202h to tilt up.

[0056] While the counterweight block 202d and the second connecting block 202h are tilted upward, the connecting rod 202e, the arc-shaped contact rod 202f and the first connecting block 202g sink. When the bottom of one end of the mud receiving plate 201a away from the counterweight block 202d contacts and limits the poured concrete, the end of the arc-shaped contact rod 202f contacts the side of the plate body 104 away from the connecting rod 202e and applies pressure to the plate body 104 to offset the pressure applied to the side of the plate body 104 close to the connecting rod 202e when part of the liquid concrete is poured.

[0057] At the same time, when the end of the mud receiving plate 201a close to the counterweight block 202d is tilted upward, the tensile chain 203b is stretched straight between the plate body 104 and the mud receiving plate 201a, thereby applying a pulling force to the side of the plate body 104 close to the connecting rod 202e, and partially offsetting the pressure applied to the side of the plate body 104 close to the connecting rod 202e when the liquid concrete is poured. The advantage of this arrangement is to prevent the pressure of the liquid concrete on the plate body 104 from causing the connection between the plate body 104 and the second embedded steel bar 105 to loosen, and to prevent the plate body 104 from being displaced and causing defects such as unevenness, honeycombs or voids on the concrete surface, thereby preventing the density and durability of the dam structure from being reduced, and avoiding the risk of increasing damage to the dam.

[0058] Example 3

[0059] Reference Figure 1 to Figure 6, which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that by setting the knocking piece 203, the advantage of such a setting is that not only the Z-shaped impact rod 203d knocks the connecting rod 202e to make a sound, reminding the staff that the concrete can continue to be poured, but also the Z-shaped impact rod 203d pushes away the liquid concrete slag that falls on the connecting rod 202e, preventing the liquid concrete slag from falling along the connecting rod 202e to the side of the plate 104 away from the connecting rod 202e and falling, thereby preventing people from being hit.

[0060] Specifically, the knocking member 203 includes a second connecting ring 203e fixedly connected to the plate body 104, a stretching chain 203b is arranged on the second connecting ring 203e, a first connecting ring 203c is arranged at one end of the stretching chain 203b away from the plate body 104, the first connecting ring 203c is fixedly connected to the mud receiving plate 201a, a mounting plate 203a is slidably sleeved on the stretching chain 203b, a gap is provided at the sliding sleeve of the mounting plate 203a and the stretching chain 203b, a Z-shaped impact rod 203d is arranged on the mounting plate 203a, and the height of the Z-shaped impact rod 203d away from the end of the mounting plate 203a is higher than the top height of the connecting rod 202e.

[0061] The stretching chain 203b is close to the plate body 104 and the top of the mud receiving plate 201a. When the liquid concrete covers the striking piece 203, the pouring stops.

[0062] The height of one end of the stretched chain 203b near the first connecting ring 203c is higher than the height of one end of the stretched chain 203b near the second connecting ring 203e, which is beneficial to improve the efficiency of the Z-shaped impact rod 203d hitting the connecting rod 202e when the mounting plate 203a slides.

[0063] When the stretch chain 203b is in a stretched state, the height of the end of the Z-shaped impact rod 203d away from the stretch chain 203b is higher than the top height of the connecting rod 202e, and there is a gap between the end of the Z-shaped impact rod 203d away from the mounting plate 203a and the top of the connecting rod 202e.

[0064] There is a gap at the sliding sleeve joint between the mounting plate 203a and the stretching chain 203b, which facilitates the left and right swinging of the mounting plate 203a.

[0065] In summary, by setting the knocking piece 203, when the stretching chain 203b between the plate body 104 and the mud receiving plate 201a is pulled to a straight state by the upturned end of the mud receiving plate 201a, the poured liquid concrete falls on the stretching chain 203b under the action of gravity and exerts pressure on the stretching chain 203b, causing the stretching chain 203b to deform and generate elastic potential energy, driving the mounting plate 203a to slide slightly on the stretching chain 203b, and the mounting plate 203a makes the Z-shaped impact rod 203d move away from the end of the stretching chain 203b toward the connecting rod 202e, not only knocking the connecting rod 202e but also sliding along the top arc of the connecting rod 202e in the direction away from the plate body 104 and pushing away the concrete slag falling on the connecting rod 202e and moving in the direction away from the plate body 104. The Z-shaped impact rod 203d is movable, and there is a gap at the sliding sleeve joint of the mounting plate 203a and the stretching chain 203b, so that the Z-shaped impact rod 203d is not in the same straight line when it descends and collides with the connecting rod 202e. Therefore, when the Z-shaped impact rod 203d pushes away the concrete slag, the concrete slag moves to the two sides of the connecting rod 202e and falls. The concrete slag falls on the stretching chain 203b and bounces off, so that the stretching chain 203b is reset and reciprocates until the liquid concrete completely covers the striking piece 203. The advantage of such a setting is that not only the Z-shaped impact rod 203d knocks on the connecting rod 202e to make a sound, reminding the staff that the concrete can continue to be poured, but also the Z-shaped impact rod 203d pushes away the liquid concrete slag that falls on the connecting rod 202e, preventing the liquid concrete slag from falling along the connecting rod 202e to the side of the plate body 104 away from the connecting rod 202e and falling, so as to prevent people from being hit.
