Technical Field

[0001] The utility model relates to the technology of reinforced arch frames, and more specifically, it relates to a ductile reinforced arch frame for water conservancy dams. Background Art

[0002] The arch frame for water conservancy dams is a framework structure used to enhance the stability of the dam slope structure. This kind of arch frame plays a key reinforcement role in the dam project, and can effectively disperse and bear external loads, preventing the dam from deforming or being damaged.

[0003] In actual production, a dam usually includes a base layer and a dam body wrapped outside the base layer. The base layer is usually selected on a deep sediment layer, which is conducive to ensuring the stability of the dam. The dam body is usually made of concrete or the like by pouring. The main function of the dam body is to provide protection for the base layer. In the prior art, in order to ensure that the arch frame has a good supporting effect on the slope of the dam body, usually the prefabricated arch frame formwork is pulled to the construction site for installation, and then concrete is poured on the arch frame formwork to complete the installation of the arch frame. When installing the arch frame formwork on the slope, adjacent two arch frame formworks are usually rigidly connected by steel bars. People need to cut the steel bars according to the length of the site, and then bundle the steel bars and weld the two ends of the steel bar bundle to the adjacent two arch frames respectively, which is rather cumbersome.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a ductile reinforced arch frame for water conservancy dams.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A ductile reinforced arch frame for water conservancy dams includes a base layer, a dam body wrapped outside the base layer, and several arch frames installed on the slope of the dam body. One side of the arch frame is provided with several inserting rods inserted into the base layer. Adjacent two arch frames are connected to each other through a connecting member. The connecting member includes a telescopic connecting rod and connecting rings fixed at both ends of the connecting rod. The two connecting rings are respectively fixed on the adjacent two arch frames.

[0007] The utility model is further arranged as follows: The arch frame includes an arc-shaped support one and two support twos respectively fixed at both ends of the support one. Several inserting rods are equidistantly distributed along the arc length direction of the support one. The connecting ring is sleeved on the support two.

[0008] The utility model is further arranged as follows: The connecting ring is provided with a through hole, and the support two is provided with a long groove. A fastening bolt passes through the through hole and the long groove together.

[0009] The utility model is further configured that: the connecting rod comprises two long rods, a kidney-shaped hole is formed at one end of each long rod away from the connecting ring, and the two long rods are connected by the same limiting bolt passing through the two kidney-shaped holes.

[0010] The utility model is further configured that: a groove is formed in the side wall of the first bracket facing away from the inserting rod, and a grouting groove communicating with the groove is formed in the second bracket.

[0011] The utility model is further configured that: every two adjacent arch frames are connected by two connecting pieces.

[0012] The utility model is further configured that: the arch frames and the connecting pieces are both made of Q235 steel.

[0013] In summary, the utility model has the following beneficial effects: when people install the arch frames, the inserting rods are inserted into the base layer, and the inserting rods inserted into the base layer can play a certain pre-fixing role on the incompletely fixed arch frames, so as to facilitate the subsequent construction of the arch frames by people. By adjusting the length of the connecting rod and installing the two connecting rings on two adjacent arch frames, when people determine the positions where the arch frames need to be placed according to the actual situation of the construction site, the adjustable connecting rod enables the distance between the connecting rings to be adjusted, and then the connecting rings are installed on the arch frames. Compared with cutting steel bars according to the actual size on site and welding them on the arch frames, using the connecting rod and the connecting rings is more convenient for connecting adjacent arch frames. The inserting rods inserted into the base layer enable one end of the arch frame to be better connected with the base layer, and the inserting rods can play a certain supporting role on the arch frames.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] The ductile reinforcement arch frame for a water conservancy dam, such as Figure 1 and Figure 2As shown in the figure, it includes a base layer 1, a dam body 2 wrapped around the base layer 1, and several arch frames installed on the slope surface of the dam body 2. One side of the arch frame is welded with several insertion rods 3 inserted into the base layer 1. Adjacent arch frames are connected to each other through connectors. The connector includes a telescopic connecting rod and connecting rings 4 fixed at both ends of the connecting rod. The two connecting rings 4 are respectively fixed on adjacent arch frames. When people install the arch frame, the insertion rod 3 is inserted into the base layer 1. The insertion rod 3 inserted into the base layer 1 can play a certain pre-fixing role for the incompletely fixed arch frame, thus facilitating the subsequent construction of the arch frame by people. By adjusting the length of the connecting rod and installing the two connecting rings 4 on adjacent arch frames, when people determine the position where the arch frame needs to be placed according to the actual situation of the construction site, the adjustable connecting rod enables the distance between the connecting rings 4 to be adjusted. Then the connecting rings 4 are installed on the arch frame. Compared with cutting and welding steel bars on the arch frame according to the actual on-site dimensions, using the connecting rod and the connecting rings 4 is more convenient for connecting adjacent arch frames. The insertion rod 3 inserted into the base layer 1 enables one end of the arch frame to be better connected to the base layer 1, and the insertion rod 3 can play a certain supporting role for the arch frame. The arch frame includes an arc-shaped support 5 and two supports 6 respectively welded to both ends of the support 5. Several insertion rods 3 are equidistantly distributed along the arc length direction of the support 5. The connecting ring 4 is sleeved on the support 6. After people insert the insertion rod 3 into the base layer 1, the insertion rods 3 equidistantly distributed along the arc length direction of the support 5 can play a better supporting role for the support 5. The connecting ring 4 sleeved on the support 6 will not interfere with the insertion rod 3 welded on the support 5, so that people can better adjust the position of the connecting ring 4 on the support 6 according to the actual installation position of the arch frame.

[0020] As Figure 2 and Figure 3As shown, a through hole 7 is provided on the connecting ring 4, and a long slot 8 is provided on the bracket 2 6. A fastening bolt 9 passes through both the through hole 7 and the long slot 8. After the arch position is determined, people first adjust the connecting rod to the required length, and then put the two connecting rings 4 at both ends of the connecting rod on the brackets 2 6 of the two adjacent arches respectively, and make the center of the through hole 7 always located above the long slot 8, and then use the fastening bolt 9 to fix the connecting ring 4 on the bracket 2 6. The long slot 8 is opened, and people use the fastening bolt 9 to fix the connecting ring 4 on When the bracket 26 is moved forward, the connecting ring 4 can be slid along the outer wall of the bracket 26. This arrangement allows people to better adjust the connecting ring 4. The connecting rod includes two long rods 10. The end of the long rod 10 away from the connecting ring 4 is provided with a waist-shaped hole 11. The two long rods 10 are connected by the same limit bolt 12 passing through the two waist-shaped holes 11, and then the connecting ring 4 is set on the bracket 26 of the adjacent arch frame. First, measure the distance between the brackets 26 of the two adjacent arch frames, then place the two long rods 10 together and pass the limit bolts 12 through the two waist-shaped holes. The two long rods 10 are pre-tightened with the limit bolts 12. After the two connecting rings 4 are sleeved and fixed on the bracket 2 6, the pre-tightened limit bolts 12 are fully tightened. At this time, the two long rods 10 are completely fixed by the limit bolts 12. The fixed long rods 10 can better connect the two adjacent arch frames. A groove 13 is provided on the side wall of the bracket 1 5 facing away from the insertion rod 3, and a grouting groove 14 connected to the groove 13 is provided in the bracket 2 6. After people fix the arch frame, they need to pour concrete. To fix the arch frame to the dam body 2, people can pour concrete in the groove 13 and the grouting groove 14, and the long groove 8 is also connected to the grouting groove 14. After the concrete solidifies normally, the concrete in the groove 13 and the grouting groove 14 can better fix the arch frame to the dam body 2 with the concrete on the outer wall of the arch frame, so that the arch frame can provide better support for the dam body 2. At the same time, the concrete in the grouting groove 14 can better fix the fastening bolts 9 passing through the long groove 8, so that the fastening bolts 9 are not easy to slide relative to the arch frame.

[0021] like Figure 2 As shown, two adjacent arch frames are connected by two connecting parts. Compared with connecting two adjacent arch frames with only one connecting part, the arch frames connected by two connecting parts are more stable, so that the arch frames can be better constrained from each other, so that the connected arch frames can better provide support for the dam body 2. The arch frames and connecting parts are made of Q235 steel, wherein the bracket 1 5 of the arch frame is made of Q235 channel steel through a bending process, and the bracket 2 6 is made of Q235 square tube. Q235 has good toughness. The arch frames and connecting parts made of Q235 steel can better provide support for the dam body 2. At the same time, the cross-section of the Q235 channel steel itself is C-shaped, which eliminates the subsequent grooving process, and the Q235 square tube itself is a hollow square tube, which can also save the process of opening the grouting groove 14, thereby better ensuring the production speed of the arch frame.

[0022] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
