Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete construction joint, especially to a device for preventing concrete construction joint misalignment. BACKGROUND

[0002] The key to preventing concrete construction joint misalignment lies in ensuring the flatness and perpendicularity of the construction joint, which requires strict formwork inspection and reinforcement before concrete pouring to ensure the stiffness and stability of the formwork; during concrete pouring, appropriate vibration methods should be used to avoid stratification and segregation of concrete, and the pouring speed and height of concrete should be controlled to prevent formwork deformation due to excessive concrete pressure; after concrete pouring is completed, timely maintenance and inspection are needed to find and repair misalignment problems to ensure the integrity and stability of the concrete structure.

[0003] A device for preventing concrete construction joint misalignment is disclosed in Chinese patent CN219343997U, which includes a K plate, a screw, and a nut. The screw is connected to the lower concrete wall. The K plate is connected to the screw through the nut. A groove is formed between the upper part of the K plate and the lower concrete wall, and an upper formwork is arranged in the groove. The K plate and the upper formwork are attached to the outer surface of the lower concrete wall. The screw is pre-buried in the wall, and the K plate, the first pressure-bearing wooden block, and the second pressure-bearing wooden block all penetrate the screw. The K plate, the first pressure-bearing wooden block, and the second pressure-bearing wooden block are fixed by double nuts. The upper formwork is supported by the K plate, which can effectively prevent formwork expansion and bursting, reduce misalignment at the joint of the concrete structure, and recycle the steel K plate after removal, reducing construction costs.

[0004] In the prior art, during the segmented butt joint pouring of concrete construction joints, appropriate auxiliary positioning devices need to be installed. However, such positioning devices are generally sealed structures, which have disadvantages in overflow and exhaust, and can easily lead to insufficient pouring quality. UTILITY MODEL CONTENT

[0005] The utility model aims at solving the shortcomings in the prior art and provides a device for preventing concrete construction joint misalignment.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A device for preventing concrete construction joint misalignment, comprising a construction joint outer box and a partition plate, further comprising:

[0008] The overflow buffer piece comprises a sliding groove arranged on one side of the construction joint outer box, a sliding box slidingly arranged on one side of the sliding groove, a base arranged on the side of the sliding box, a positioning column slidingly arranged in the base, and a tension spring connected and installed between the base and the construction joint outer box.

[0009] Further technical solutions, the sliding groove and the sliding box are abutted and ground.

[0010] Further technical solutions, further comprising:

[0011] The pressure relief assembly comprises overflow grooves arranged on the two side tables of the construction joint outer box.

[0012] Further technical solutions, the pressure relief assembly further comprises an air hole installed at the bottom of the construction joint outer box, an air groove arranged at the back of the air hole, a guide groove abutted on one side of the air groove, and an air valve abutted and installed on one side of the guide groove.

[0013] Further technical solutions, further comprising:

[0014] The mounting assembly comprises mounting holes arranged on the periphery of the construction joint outer box, rods installed in the mounting holes, positioning plates arranged on the surface of the rods, and locking covers abutted and installed between adjacent rods.

[0015] Further technical solutions, the abutted parts of the adjacent rods are provided with external threads, and the locking cover is provided with internal threads in the inside.

[0016] Further technical solutions, the construction joint outer box, the overflow buffer piece, the pressure relief assembly and the mounting assembly are arranged in a symmetrical structure.

[0017] Compared with the prior art, the device for preventing concrete construction joint misalignment has the following beneficial effects:

[0018] The overflow buffer piece is arranged at the abutted pouring position of the construction joint partition plate, which can easily solve the overflow problem caused by stress concentration. A sliding groove for sliding the sliding box is arranged in the middle part of the outer box. Once the pressure is too large, the sliding box will slide outward within a limited range under the positioning action of the positioning column and the traction action of the tension spring, thereby offsetting the stress concentration and improving the pouring quality.

[0019] The pressure relief assembly is arranged to achieve the buffering effect in terms of internal pressure and internal air pressure of the concrete. The internal pressure of the concrete is discharged through the overflow groove, and the air pressure is discharged through the air valve, the air groove, the guide groove and the air hole, so that the internal structure of the concrete is more compact.

[0020] By setting in the installation assembly, the adjacent construction joint outer box needs to be positioned, otherwise the misalignment problem will occur; therefore we realize the locking and fixing effect through the locking cover between the adjacent positioning rod members.

[0037] Working principle:

[0038] In the actual design process of the utility model, in order to avoid the following defects in the prior art: in the prior art, the concrete construction joint needs to be provided with a corresponding auxiliary positioning device during sectional joint pouring, but the positioning device is generally a sealed structure, and there are disadvantages in overflow and exhaust, and the pouring quality is prone to be insufficient. The overflow buffer 2, the pressure relief assembly 3 and the mounting assembly 4 are proposed.

[0039] Overflow buffer 2:

[0040] The assembly mainly solves the stress concentration problem of the concrete sectional pouring butt joint part - the partition plate 10 part, and the sliding groove 5 and the sliding box 6 are arranged at the stress concentration part of the construction joint outer box 1; the sliding box 6 realizes the limiting and buffering of the overhanging interval through the positioning column 8 and the tension spring 9 on the base 7. Meanwhile, the cavity structure inside the sliding box 6 has a certain storage effect.

[0041] Pressure relief assembly 3:

[0042] The assembly realizes pressure relief in the concrete liquid and the internal air pressure, and further makes the internal structure more compact and stable. When the concrete is poured excessively, the excessive concrete will stay at the overflow groove 11 part and relieve pressure. When the air pressure inside the concrete is too large and the air bubbles are too many, the air bubbles are discharged through the air hole 12, the air groove 13, the guide groove 14 and the air valve 15, so that a large number of air bubbles do not appear inside to affect the structural strength.

[0043] Installation assembly 4;

[0044] The installation assembly is the structure for positioning the butt joint of the adjacent construction joint outer box 1, avoiding the problem of misalignment. The adjacent rod members 16 are locked and fixed through the locking cover 18, and the position of the construction joint outer box 1 is positioned through the positioning plate 17.
