Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building construction devices, in particular to a beam-column joint different-strength-grade concrete isolation device. BACKGROUND

[0002] In the process of building construction, different-strength-grade concrete is used for pouring due to different loads, so that the concrete strength of the core area of the beam-column joint is higher than that of the beam plate. Therefore, when the beam and the column are poured separately, isolation needs to be set to prevent the high-strength concrete from being mixed with the low-strength concrete.

[0003] For the junction of different-strength-grade concrete, a construction method of using iron wire to bind into a dense mesh is usually adopted. The dense mesh needs to be cut according to the section size of the junction, but this construction method is not easy to remove in the later stage and cannot be reused, which wastes manpower and resources. If the steel mesh or the quick and easy closing mesh is not cleaned properly, it will also cause rust and even leakage in the later stage, affecting the use function of the concrete. In the process of pouring some concrete, a detachable isolation tool is used to isolate the beam-column joint, but the size of this kind of isolation device is usually fixed and cannot be used for beam-column joints of different sizes, making it difficult to isolate the pouring process of different-strength-grade concrete.

DETAILED DESCRIPTION

[0029] The embodiments will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different figures represent the same or similar elements. The following description of embodiments is not representative of all embodiments consistent with the present application. Rather, it is merely an example of a system and method consistent with some aspects of the present application as detailed in the claims.

[0030] When using iron wire to tie into a dense mesh to isolate concrete of different strength grades, it is not easy to remove at the later stage of construction, cannot be used for circulation, and wastes manpower and resources. If the steel mesh or the quick and easy closing mesh is not cleaned properly, it will also cause rust and even leakage at the later stage, affecting the use function of the concrete. When using a removable isolation tool to isolate the concrete of different strength grades of the beam-column joint, the size of such isolation device is usually fixed and cannot be used for beam-column joints of different sizes, making it difficult to isolate the concrete pouring process of different strength grades.

[0031] To solve the problem of difficult isolation of concrete pouring process of different strength grades, the embodiments of the present application provide a beam-column joint different strength grade concrete isolation device, as shown in Figures 2-3 The isolation device comprises at least one isolation assembly 100, the isolation assembly 100 comprises a mounting base 110, an isolation plate 120 and an elongated plate 130, and a plurality of isolation plates 120 are arranged along the length direction of the mounting base 110.

[0032] Referring to Figure 4 The mounting base 110 can be a long strip structure, the mounting base 110 is provided with a first groove 112 along the length direction, and the cross section of the first groove 112 can be rectangular. The isolation plate 120 penetrates the first groove 112, so that the isolation plate 120 can be connected with the mounting base 110 through the first groove 112. By arranging the isolation plate 120 and the mounting base 110 in sliding connection, the isolation plate 120 can be placed at any position of the mounting base 110 by sliding, so as to adjust the distance between the adjacent two isolation plates 120. By arranging a plurality of isolation plates 120 on the mounting base 110, an isolation surface can be formed, and different strength concretes can be isolated during pouring. At the same time, since the distance between the isolation plates 120 is adjustable and the position is variable, when encountering the obstruction of the beam-column reinforcement, the reinforcement can be avoided, and the installation of the isolation device will not be hindered.

[0033] The top of the lengthened plate 130 is clamped with the bottom of the isolation plate 120, and by clamping the lengthened plate 130 with the bottom of the isolation plate 120, different height sizes of the beam column can be adapted, and when the height size of the beam column is small, the lengthened plate 130 can be directly removed, which is simple to operate and has strong practicality.

[0034] One end of the mounting base 110 is detachably connected with the connecting block 150, and the other end of the mounting base 110 is detachably connected with the mounting groove 160, and two adjacent mounting bases 110 are detachably connected through the connecting block 150 and the mounting groove 160, and by arranging the connecting block 150 and the mounting groove 160, multiple mounting bases 110 can be connected to adapt to different width sizes of the beam column, and when the width size of the beam column is small, the isolation at the joint of the beam column can be performed by only one isolation assembly 100.

[0035] The isolation device provided by the embodiment of the application can form an isolation surface by arranging multiple movable isolation plates 120 on the mounting base 110, and different strength concretes can be isolated during pouring. By arranging multiple detachably connected isolation assemblies 100 and the lengthened plate 130 clamped with the isolation plate 120, different sizes of the beam column can be adapted, and the universality of the isolation device is improved. The problem of difficulty in isolation during pouring of different strength grade concretes can be solved.

[0036] Referring to Figure 5 and Figure 6 , the isolation plate 120 includes an isolation plate body and a limiting top block 121, and the limiting top block 121 is arranged at the top end of the isolation plate body. The isolation plate 120 can have a T-shaped structure. The thickness of the isolation plate body can meet the strength, for example, the thickness of the isolation plate body can be less than 10 mm. The first groove 112 is arranged on the top surface of the mounting base 110 and penetrates the mounting base 110. In some embodiments, the difference between the thickness of the isolation plate body and the cross-sectional width of the first groove 112 is between 1-2 mm, so that the isolation plate 120 can slide in the mounting base 110 and will not shake greatly. The top surface of the mounting base 110 is also provided with the second groove 111, and the limiting top block 121 is arranged in the second groove 111, and by arranging the second groove 111, the limiting top block 121 can be hidden in the mounting base 110, and when the isolation plate 120 is installed, the probability that the construction personnel accidentally touch the isolation plate 120 can be reduced, thereby causing the position of the isolation plate 120 to change. It can be understood that the cross-sectional width of the second groove 111 is greater than the cross-sectional width of the first groove 112, and by arranging the limiting top block 121 in the second groove 111, the isolation plate 120 can be limited by the second groove 111 through the limiting top block 121.

[0037] The top of the lengthened plate 130 is provided with a clamping block 131, the bottom of the isolation plate body is provided with a first clamping groove 122, and the top of the lengthened plate 130 is clamped to the bottom of the isolation plate 120 through the clamping block 131 and the first clamping groove 122. In some embodiments, the cross section of the clamping block 131 is T-shaped, and the cross section of the first clamping groove 122 is also T-shaped, and the T-shaped clamping block 131 is clamped to the first clamping groove 122. Through the clamping connection, the lengthened plate 130 can be quickly installed and removed, which facilitates the construction personnel to assemble the isolation assembly 100.

[0038] Again referring to Figure 3 and Figure 4 , the isolation assembly 100 further comprises a tightening rod 140, the side surface of the mounting base 110 is provided with a long hole 113, the side surface of the limiting top block 121 close to the long hole 113 is provided with a tightening hole, and the tightening rod 140 is in abutment with the inner side surface of the mounting base 110 away from the long hole 113 after penetrating through the tightening hole. In some embodiments, the tightening hole is a threaded hole, and the tightening rod 140 can be a standard bolt, so that the tightening rod 140 is threadedly connected with the limiting top block 121. After the tightening rod 140 is threadedly connected with the limiting top block 121, the isolation plate body is reversely moved under the action of the limiting top block 121 by abutting the inner side surface of the mounting base 110 away from the long hole 113, the first groove 112 is tightened, and the isolation plate 120 can be fixed to reduce the probability of left and right stringing of the isolation plate 120 in the mounting base 110.

[0039] Referring to Figures 7-8 , the side surface of the connecting block 150 is provided with a connecting hole, and the connecting block 150 is detachably connected with the mounting base 110 through the connecting hole. The side surface of the mounting groove 160 is also provided with a connecting hole, and the mounting groove 160 is detachably connected with the mounting base 110 through the connecting hole. In some embodiments, the connecting hole is a stepped hole, and when the connecting block 150 and the mounting groove 160 are detachably connected with the mounting base 110 through bolts, the bolts can be hidden, and the size of the connecting block 150 and the mounting groove 160 can be reduced.

[0040] The two ends of the connecting block 150 are provided with bosses, and the bottom surface of the mounting groove 160 is provided with a second clamping groove 161, and the mounting groove 160 is clamped to the connecting block 150 through the bosses and the second clamping groove 161. In some embodiments, the second clamping groove 161 is a C-shaped structure, the height of the second clamping groove 161 is equal to the width of the connecting block 150, and the connecting hole can be arranged on the top of the mounting groove 160, i.e., above the second clamping groove 161.

[0041] In some embodiments, the isolation assembly 100 further comprises a handle, and the handle is arranged on the top surface or the side surface of the mounting base 110. The handle can be arranged to facilitate the isolation device to be taken out. Since the position of the handle can be arranged according to the use habit, the handle is not shown in the figure.

[0042] Referring toFigure 1 In the illustration, high-strength grade concrete 200 is poured in the shaded position of the beam column, and low-strength grade concrete is poured in the blank position. During construction, the number of isolation assemblies 100 required according to the size of the beam column is selected, assembled together, and the assembled isolation assembly 100 is arranged at the position of the beam column joint. The isolation assembly 100 forms an isolation surface, at which time different strength grade concretes can be poured. After the high-strength grade concrete 200 is poured and the high-strength grade concrete 200 is initially cured, the isolation assembly 100 is slowly pulled out, used for the next pouring process, and then the low-strength grade concrete can be poured.

[0043] As can be seen from the above technical solutions, the embodiment of the application provides a beam column joint different strength grade concrete isolation device, which comprises at least one isolation assembly 100. The isolation assembly 100 comprises a mounting base 110, an isolation plate 120, and an extension plate 130. A plurality of isolation plates 120 are arranged along the length direction of the mounting base 110. The mounting base 110 is provided with a first groove 112 along the length direction, and the isolation plate 120 is slidably connected to the mounting base 110 through the first groove 112. The top of the extension plate 130 is clamped to the bottom of the isolation plate 120. One end of the mounting base 110 is detachably connected to a connecting block 150, and the other end of the mounting base 110 is detachably connected to a mounting groove 160. Two adjacent mounting bases 110 are detachably connected through the connecting block 150 and the mounting groove 160. By arranging a plurality of movable isolation plates 120 on the mounting base 110, an isolation surface can be formed, and different strength concretes can be isolated during pouring. By arranging a plurality of detachably connected isolation assemblies 100 and the extension plate 130 clamped to the isolation plate 120, the isolation device can be adapted to beam columns of different sizes, improving the versatility of the isolation device and solving the problem of difficulty in isolating different strength grade concretes during pouring.
