In order to prevent low-strength concrete from flowing into high-strength concrete pouring areas, concrete interceptors are needed.

[0003] Existing concrete interceptors mostly use wire mesh interceptors, which are usually intercepted by tying the wire mesh inside the steel cage of the beam and column. There are also square wood formwork combined interceptors for concrete interception. Due to the high density of steel bars, the above two interception methods are difficult to operate and difficult to dismantle later, and cannot be quickly disassembled and installed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Aims to propose a new type of louvered concrete interceptor,

[0030] according to Figures 1 to 6 As shown, it includes a steel plate 1,

[0031] The steel plate 1 extends in the left-right direction, and is provided with a plurality of slots spaced apart from each other on the left-right direction.

[0032] The slot includes a through hole 2, which extends in the front-to-back direction. The through hole 2 is opened on the steel plate 1, and the through hole 2 is transparent from top to bottom. A circular hole 3 extending up and down is opened in the middle of the through hole 2, and the circular hole 3 is transparent from top to bottom. The diameter of the circular hole 3 is greater than the width of the through hole 2.

[0033] An interception piece is provided in the slot, which includes a support rod 5 and an elastic plastic plate 8. The support rod 5 extends up and down. The support rod 5 is made of high-strength round steel. The lower side of the support rod 5 is connected to the elastic plastic plate 8 through a fixing piece 9. The fixing piece 9 can be made of rivets or binding tape. The elastic plastic plate 8 is located below the steel plate 1. The elastic plastic plate 8 extends in the up and down directions. The support rod 5 can slide up and down and rotate left and right in the circular hole 3. The width of the perforation 2 is greater than the width of the elastic plastic plate 8, and the length of the perforation 2 is greater than the length of the elastic plastic plate 8. The elastic plastic plate 8 can pass through the perforation 2.

[0034] The limiting member is a limiting rib 6, and limiting ribs 6 are provided on both sides of the circular hole 3. The two limiting ribs 6 are positioned correspondingly on the left and right. The limiting ribs 6 are fixedly connected to the upper surface of the steel plate 1, and the limiting ribs 6 extend in the up and down directions.

[0035] The distance between the top of the elastic plastic plate 8 and the connection point of the fixing rod 7 on the support rod 5 is 20 mm greater than the height of the limiting rib 6 , and the outer surface of the fixing rod 7 contacts the outer surfaces of the two limiting ribs 6 on the left and right sides of the corresponding circular hole 3 .

[0036] A fixing rod 7 is fixedly connected to the support rod 5, and the fixing rod 7 extends in the left and right directions. The connection between the fixing rod 7 and the support rod 5 is the middle part of the fixing rod 7. The distance between the two limiting ribs 6 on the left and right sides of the same slot is less than the length of the fixing rod 7.

[0037] A stabilizing steel plate 10 is provided on the upper side of the steel plate 1, and the stabilizing steel plate 10 and the steel plate 1 are fixedly connected by a support column. A second slot is provided on the stabilizing steel plate 10. The shape of the second slot is the same as the slot, and the position of the second slot corresponds to the slot one by one. The upper side of the outer surface of the support rod 5 is plugged into the inside of the circular hole 3 in the second slot corresponding to the position above and below, and the upper end of the support rod 5 passes through the second slot.

[0038] The upper end of the support rod 5 is fixedly connected with a rotating handle 4 . The width of the rotating handle 4 is greater than the width of the through hole 2 . The rotating handle 4 is located on the upper side of the stabilizing steel plate 10 .

[0039] The width of the elastic plastic plate 8 is 3 mm larger than the distance between two adjacent slots on the left and right, which facilitates the overlapping of two adjacent elastic plastic plates 8 in the steel cage and improves the concrete interception effect.

[0040] Construction principle: The construction workers first install the steel plate 1 on the upper surface of the beam-column steel cage, and then pass the support rod 5 and the elastic plastic plate 8 through the two corresponding slots in the upper and lower positions in turn. When the elastic plastic plate 8 has passed through the slot on the steel plate 1 and the fixing rod 7 is still above the limiting rib 6, the construction workers rotate the rotating handle 4, and the rotating handle 4 drives the support rod 5 to rotate, and the rotation of the support rod 5 drives the fixing rod 7 to rotate. When the fixing rod 7 rotates to a direction parallel to the steel plate 1, the construction workers continue to apply downward force to the support rod 5, so that the support rod 5 continues to move downward until the outer surface of the fixing rod 7 contacts the outer surface of the steel plate 1. At this time, the left and right sides of the fixing rod 7 are in contact with the outer surfaces of the adjacent limiting ribs 6. At this time, the fixing rod 7 cannot rotate, so that the elastic plastic plate 8 cannot rotate when subjected to force.

[0041] Then the construction workers install all the intercepting parts in sequence according to the above method. When all the intercepting parts are installed, two adjacent elastic plastic plates 8 overlap and contact each other, so that all the elastic plastic plates 8 are combined together to form a louver intercepting wall.

[0042] When use is completed, the construction worker pulls the rotating handle 4 to move upward. When it moves to the fixed rod 7 above the limiting rib 6, the construction worker rotates the rotating handle 4. The rotation of the rotating handle 4 drives the support rod 5 to rotate. The rotation of the support rod 5 drives the elastic plastic plate 8 until the elastic plastic plate 8 is parallel to the perforation 2. Then the construction worker pulls the rotating handle 4 to continue upward, thereby pulling out the intercepting piece.

[0043] The construction workers pulled out all the intercepting parts according to the above method, and then removed the steel plate 1, thereby completing the dismantling of the interceptor.

[0044] In this way, the interceptor can insert the intercepting part into the steel plate 1 from the top of the steel cage for installation, and then all the elastic plastic plates 8 form a louver intercepting wall in the beam and column steel cage to intercept the concrete. It can also be quickly dismantled after use. Inserting and installing from the top can avoid disassembly and assembly work in the steel cage, thereby achieving quick disassembly and assembly and saving manpower.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
