Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, and in particular to a concrete armored joint structure and a concrete construction process. Background Art

[0002] When pouring traditional large-volume concrete floors, it is necessary to mark, cut and clean the floor within a certain period of time after pouring the concrete, and fill the cut floor with glue so that the concrete floor has the ability to resist its own expansion force and external pressure to prevent the floor from cracking. When cutting the floor, a large amount of dust will be generated on site, which requires additional adsorption and cleaning. There is a waiting period of several days for the concrete to solidify before cutting, and it needs to be cleaned before gluing after cutting, resulting in a long construction period. The traditional process only cuts expansion joints on the floor, which can only be used to resist the lateral expansion force of the concrete and prevent the concrete from being squeezed against each other due to thermal expansion and contraction. For areas with large concentrated stress such as column bases and wall corners, they are prone to uneven pressure and settlement, and even cracking. Based on the above shortcomings, there is a need for a concrete construction process that can avoid settlement and cracking in areas with large stress and has a short construction period. Summary of the invention

[0003] One of the purposes of the present invention is to provide a concrete armor joint structure, which solves the problem that the existing concrete expansion joints cannot be used in stress concentration areas such as column corners and wall corners.

The sheath is arranged in one side wall of the expansion joint, and a part of the conductive member is arranged in the other side wall of the expansion joint. The other part of the conductive member is telescopically connected in the sheath. The conductive member transmits the displacement and pressure of one side of the expansion joint to the other side of the expansion joint through the sheath to prevent the concrete floors on both sides of the expansion joint from settling and dislocation. The conductive member can slide in the sheath and can follow the width change of the expansion joint to resist deformation, and has high stability in use.

[0006] Furthermore, the sheath includes a baffle and a sleeve part, the baffle is arranged on the side wall of the expansion joint, one end of the sleeve part is connected to the baffle, the conductive part is telescopically connected in the sleeve part, and the baffle is used to fix the position of the sleeve part so that the conductive part can stably telescopically move in the sleeve part.

[0007] Furthermore, the sheath also includes a stabilizing frame, which is arranged on the outer wall of the sleeve and is used to improve the bonding degree between the sleeve and the concrete floor.

[0008] Preferably, the cross-section of the sleeve is set to be rectangular, and the side wall of the sleeve is provided with anti-slip grooves to increase the contact area with concrete and improve stability.

[0010] As a better option, it also includes a support member, which is arranged between two adjacent shaping plates to prevent the shaping plates from becoming unstable.

[0011] Furthermore, it includes a first guard plate and a second guard plate, wherein the first guard plate is arranged on one side wall of the expansion joint, and the second guard plate is arranged on the other side wall of the expansion joint, and the first guard plate and the second guard plate are close to the top surface of the concrete floor, one end of the first anchor bolt is connected to the first guard plate, and one end of the second anchor bolt is connected to the second guard plate, which are used for shaping the poured concrete, so that the overall appearance is beautiful.

[0012] Preferably, it also includes a shaping rod, which penetrates the first guard plate and the second guard plate on both side walls of the expansion joint and is used for integrally installing the concrete armored joint structure for easy transportation.

[0013] As a better option, it also includes a buffer layer, which is arranged in the expansion joint. The buffer layer is made of flexible material to prevent the expansion joint from being blocked, making the appearance beautiful and being able to effectively absorb vibration.

[0014] The second purpose of the present invention is to provide a concrete construction process, which solves the problem of long construction period and dust pollution of existing concrete expansion joints.

[0015] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is as follows:

[0016] A concrete construction process, used to realize the concrete armored joint structure, comprises the following steps:

By pre-installing the armored seam structure, later cutting and dust can be avoided. The armored seam structure can be flexibly combined, absorbs pressure in all directions, and prevents local settlement of column corners and wall corners. BRIEF DESCRIPTION OF THE DRAWINGS
