Building wall caulking gun

Abstract

The invention provides a building wall caulking gun. A gun barrel is fixed on a stock; the structure of the gun barrel is that a taper beak is molded at the front end of a cylindrical body; a beak opening is formed in the end part of the taper beak; a cylindrical body gap and a cylindrical body strip hole are formed in the upper part of the cylindrical body; a seal cover is formed at the bottom part of the cylindrical body; the structure of a caulking bag is that a tapered bag opening is formed in the front end of a cylindrical bag body; mortar is arranged in the caulking bag; the upper part of a pressure sleeve is fixedly connected with a hand handle; the hand handle is inserted into the cylindrical body strip hole; the right end of the spring is pressed on the seal cover and the left end of the spring is pressed on the pressure sleeve; the spring is inserted into the pressure sleeve in a sleeving manner; a switch block is hinged with a gun handle; one end of a torsional spring is fixed on the gun handle and the other end of the torsional spring props against the switch block; a plurality of pressure sleeve grooves are formed in the pressure sleeve; and the top end of the switch block extends into a bottom hole of a gun cylinder and props against the pressure sleeve grooves.

Description

Technical field: [0001] The invention relates to the technical field of construction, and more specifically relates to a ditch auxiliary tool used for ditching of building walls. Background technique: [0002] The installation of ceramic exterior wall bricks (split bricks) is mainly paving, and generally 6-8mm gaps are left between the wall bricks, and cement mortar is used for jointing. The traditional cement mortar pointing methods include grout batch pointing method and ash-adding pointing method. The batch grout pointing method is suitable for glazed bricks. It is characterized by fast construction speed, but the mortar loss is much and the cleaning work is much, so it is not suitable for unglazed bricks. Glazed bricks and rough-faced bricks; the ash-adding and pointing method is to use dry ash, and use a special pallet and pointing trowel for pointing. It is suitable for glazed bricks, unglazed bricks, ceramic split bricks, etc., but its construction efficiency is low. ...

Problems solved by technology

The traditional cement mortar pointing methods include grout batch pointing method and ash-adding pointing method. The batch grout pointing method is suitable for glazed bricks. It is characterized by fast construction speed, but the mortar loss is much and the cleaning work is much, so it is not suitable for unglazed bricks. Glazed bricks and rough-faced bricks; the ash-adding and pointing method is to use dry ash, and use a special pallet and pointing trowel for pointing. It is suitable for glazed bricks, unglazed bricks, ceramic split bricks, etc., but its construction efficiency is low. , the loss of mortar is large, which has a great influence on the quality of wall pointing and wall cleanliness

[0003] In some construction sites, the owner directly uses the seam bag to seam the wall. The disadvantage is that the mortar is corrosive to the opponent, and holding the seam bag for a long time will damage the hands.
