Clamp special for sleeve vertical grouting

Abstract

The invention provides a clamp special for sleeve vertical grouting. The clamp comprises a plurality of partition plates which are arranged at different heights and mutually parallel. A plurality of positioning holes are formed in each partition plate. A positioning bar is inserted into each positioning hole to fix the adjacent upper and lower partition plates. A plurality of grouting sleeve penetrating holes are formed in the top partition plate and used for fixing grouting sleeves. A plurality of steel bar penetrating holes are formed in the partition plates between the top partition plate and the bottom partition plate. Each steel bar penetrating hole and the corresponding sleeve penetrating hole are coincide in the vertical direction to make steel bars penetrating through the steel bar penetrating holes be inserted into the sleeves of the top. The tops of the all positioning bars on the top partition plate are provided with bending parts extending outwards. A receiving groove is formed in the upper portion of each bending part and used for storing grouting materials discharged from discharging openings of the grouting sleeves. According to the grouting clamp special for the grouting sleeves, the coaxiality of the steel bars and the sleeves are ensured, and the precision and accuracy of steel bar positioning are ensured.

Description

technical field [0001] The invention relates to the construction field, in particular to a special clamp for vertical grouting of sleeves. Background technique [0002] In prefabricated structures, the connection of steel bars as components is one of the key construction technologies. The traditional technology of steel bar connection adopts the reverse filling operation process of steel bar grouting straight thread connection joint and wallboard sleeve grouting. The steel bar grouting straight thread connection joint is a stripped rib rolling straight thread connection at one end and a cement grouting connection at the other end. A steel bar with a straight thread at the end and a ribbed steel bar are connected together with a corresponding connecting sleeve, and poured in the connecting sleeve for grouting, and then the connecting sleeve is used to combine the upper and lower ends of the steel bar. Together. figure 1 It shows a schematic diagram of construction using a ...

AI Technical Summary

Problems solved by technology

figure 1 It shows a schematic diagram of construction using a grouting sleeve. During the construction process, the positioning of the upper and lower steel bars and the casing holes is relatively cumbersome, so that the upper and lower steel bars may not be inserted straight into the sleeve, which affects the building strength. caused some adverse effects
