[0042] Example 2:

[0043] Such as Figure 1 to Figure 3 A horizontal construction joint reinforcement bolt is shown. On the basis of Embodiment 1, the connecting wall fixing member 3 includes a bottom plate 31, a protrusion 32 fixed on the bottom plate 31, and the protrusion 32 is arranged in the wall. The threaded insertion hole that matches the segment screw 1, and the inner-wall segment screw 1 is inserted into the threaded insertion hole; the screw 5 is fixedly connected to the bottom plate 31, and the screw 5 extends from the bottom plate 31 away from the side where the protrusion 32 is located. Out. The groove 26 is tapered with a diameter gradually decreasing from the open end to the bottom end, and the bottom end of the groove 26 matches the base part 21; when the base part 21 is located at the bottom end of the groove 26, The base portion 21 and the base portion 22 are both located in the groove 26. A mountain-shaped pipe clamp 6 is movably sleeved on the outer screw ...

Example Embodiment

[0044] Example 3:

[0045] A horizontal construction joint reinforcement method, such as Figure 1 to Figure 8 As shown, it includes the following steps: (a) Connect the inner wall screw 1 and the connecting wall fixing member 3, and pre-bury them in the old wall 12 in advance, so that one end of the inner wall screw 1 enters the tapered sleeve 4 , The open end of the tapered sleeve 4 is located on the side of the old wall; (b) Clean the old wall and place the wire on the old wall; tie the wall reinforcement, install the water and electricity pipelines and embedded parts, and complete the concealed project; (c) Put the inside The shear wall formwork 10 is placed vertically on the wall steel bars, and a tongue-and-groove steel plate 8 is installed on the inner side of the top of the outer shear wall formwork 11, and a groove and groove area is formed under the tongue-and-groove steel plate 8 facing the old wall. The groove area is located under the construction joint, and the spo...

Abstract

The invention discloses a horizontal construction joint reinforcing bolt and a reinforcing method based on the bolt. The horizontal construction joint reinforcing bolt comprises a wall inner section screw, wherein the two ends of the wall inner section are respectively in threaded connection with a wall outer section screw and a wall connection fixed part; the wall outer section screw comprises abase part, a pedestal part and a screw part; a threaded hole is arranged on the base part, a threaded groove communicated with the threaded hole is arranged on the pedestal part, the threaded hole andthe threaded groove are both coaxial with the screw part, and the threaded hole and the threaded groove are both matched with the wall inner section screw; the wall inner section screw is sleeved bya conical sleeve, the conical sleeve is coaxial with the wall inner section screw, a groove matched with the base part is arranged on the surface of one side facing the wall outer section screw of theconical sleeve, and the base part is embedded into the groove. The horizontal construction joint reinforcing bolt is used for solving the problems that formation of a construction joint at a new-oldwall concrete joint in the prior art is prone to have multiple quality defects, and the purposes of effectively avoiding displacement of a bottom expansion mould of a formwork and solving the qualityproblems of construction joint faulting, pulp leakage, holes and the like are achieved.

Description

technical field [0001] The invention relates to the field of concrete exterior wall construction, in particular to a horizontal construction joint reinforcement bolt and a reinforcement method based on the bolt. Background technique [0002] During the construction of cast-in-place concrete external walls, the completed structure below the construction joint is referred to as "old wall" for short, and the wall to be constructed above is called "new wall". In the prior art, there have always been quality problems such as dislocation (expansion), grout leakage, and holes in the formation of construction joints at the concrete joints of new and old walls. The reason is that the formwork support system at the interface between the old and new wall concrete is not well reinforced, and the formwork reinforcement system lacks a reliable connection with the old wall structure. When the concrete is poured and vibrated, the side pressure on the formwork will expand the lower opening ...
