Description

Technical Field

[0001] The utility model relates to the technical field related to building construction, and more specifically to a combined beam-column node concrete intercepting device. Background Art

[0002] In construction projects, beams and columns are common building structures. Different grades of concrete are often used in the structural design of beams and columns. The concrete grade strength of columns is usually higher than that of beams.

[0003] When the concrete strength grade of the wall column is two grades or more higher than that of the beam and slab, the concrete at the beam-column joint should be poured according to the concrete strength grade of the wall column; at this time, the high-grade concrete of the wall column should be poured first and then separation measures should be taken in the junction area.

[0004] Usually, wire mesh is used to intercept concrete of different strengths. However, because there are many steel bars in the beams and the on-site binding operation space is small, it is difficult to ensure the quality of the wire mesh binding, resulting in failure to intercept high-strength concrete and failure to pour high-strength concrete to the top, affecting the structural strength and wasting high-strength concrete.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0031] See also Figures 1 to 5 In the utility model, a combined beam-column node concrete interception device comprises a rectangular inner frame 1 and two U-shaped outer frames 2.

[0032] The interior of the rectangular inner frame 1 is fully provided with a special steel mesh 3, and the special steel mesh 3 is tied to the rectangular inner frame 1 with iron wire. The rectangular inner frame 1 is placed in the frame beam and fixed to the frame beam steel bars with iron wire. The two U-shaped outer frames 2 are surrounded by a wound steel mesh 4.

[0033] In this embodiment, preferably, the rectangular inner frame 1 and the two U-shaped outer frames 2 are both made of 8 mm steel bars.

[0034] In this embodiment, preferably, the two U-shaped outer frames 2 overlap each other by 100 mm, and the two U-shaped outer frames 2 are fixed to the frame beam by iron wires.

[0035] In this embodiment, preferably, the width of the rectangular inner frame 1 is:

[0036] Frame beam section width - protective layer thickness*2 - frame beam stirrup diameter*2 - frame beam waist reinforcement diameter*2.

[0037] In this embodiment, preferably, the height of the rectangular inner frame 1 is:

[0038] (Frame beam section height - protective layer thickness*2 - maximum main reinforcement diameter*2 - stirrup diameter*2)*1.414.

[0039] In this embodiment, preferably, the width of the U-shaped outer frame 2 is:

[0040] Frame beam section width - protective layer thickness.

[0041] In this embodiment, preferably, the height of the U-shaped outer frame 2 is:

[0042] (Frame beam section height - protective layer thickness*2)*1.414÷2+100.

[0043] The working principle and use process of this utility model:

[0044] Before tying the reinforcement of the frame beam, the required dimensions of the rectangular inner frame 1 and the U-shaped outer frame 2 are calculated according to the cross-sectional dimensions of the frame beam and the reinforcement conditions in the drawings. The rectangular inner frame 1 and the U-shaped outer frame 2 are processed centrally in the processing area, and the special steel wire mesh 3 and the winding steel wire mesh 4 are tied to the inside of the rectangular inner frame 1 and around the U-shaped outer frame 2 respectively by iron tying wires;

[0045] After the main reinforcement of the frame beam is tied, the rectangular inner frame 1 of the interception device can be placed into the frame beam and fixed to the frame beam steel bars with iron ties; after the stirrups of the frame beam are tied, two U-shaped outer frames 2 are installed, and the two U-shaped outer frames 2 overlap each other by 100mm and are fixed to the frame beam with iron ties.

[0046] Centralized processing is carried out in the processing area according to the cross-sectional dimensions of different frame beams. Centralized processing can solve the problem of difficulty in ensuring the binding quality of the wire mesh due to the small on-site binding operation space caused by the large number of beam reinforcements. It can effectively ensure the binding quality of the wire mesh, and the on-site installation is convenient and fast, which can effectively reduce the time for sealing the on-site beam-column nodes, speed up the on-site construction speed, and reduce human resource consumption.

[0047] When pouring concrete, the conventional construction process fails to seal the beam-column joints properly, and the vibration rod causes the high-strength concrete to flow randomly, making it difficult to pour the high-grade concrete to the top of the column. Since the rectangular inner frame 1 and the U-shaped outer frame 2 are well matched with the frame beam in size, the gap in the middle of the frame beam can be completely closed, and the quality of concrete interception can be guaranteed. The interception in place can effectively avoid the above situation and ensure that the structural strength meets the design requirements. At the same time, it can significantly reduce the waste of high-strength concrete and save costs.

[0048] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0049] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
