Joist frame for laying floor

Abstract

The invention relates to a keel support used to lay floor, which comprises dual longitudinal main keels. Wherein, it is characterized in that: it comprises dual transverse keels that spanning each main keel; the distance between nearby transverse keels is the width of 1-4 blocks of floor, to form the frame with longitudinal main keel; the main keel is the section bar with upward opening, whose bottom is fixed with dual foots; the foot comprises base and horizontal adjuster; the adjusting element of horizontal adjuster, via the opening at the bottom of main keel, extends into the main keel; said transverse keel comprises horizontal support, strength bar at the bottom and the separate column protruded at the top; the clamp part of transverse keel to the main keel has clamp groove matched with the side wall of main keel; tow sides of separate column are arranged with the wedges of nearby two floors or the concave-convex structure. The invention can improve the laying quality and speed.

Description

technical field [0001] The invention relates to a keel support frame, in particular to a keel frame used for fixing and supporting the floor when laying the floor. Background technique [0002] As a traditional floor decoration material, flooring has always been loved by people for its naturalness, comfort, softness and other advantages. There are many types of floors, including the most original solid wood floor and laminated wood floor, composite floor, etc. after various processing methods. Most floors need to use keel as the bottom support frame of the floor when laying, so the keel is the floor. Laying of indispensable auxiliary materials. [0003] When laying the floor, first fix the keel, drill holes in the corresponding position on the ground, put in the expansion pipe, fix the keel on the ground with floor nails, and then level it (usually use a level to check whether the surface of the keel is parallel to the ground to ensure The flatnes...

AI Technical Summary

Problems solved by technology

However, in actual use, the following problems often occur: ① hollow sound, the reason is that the fixation is not solid, mainly caused by the number of nails between the floor and the keel, the floor and the floor or the nails are not firm; ② the surface is uneven, the main reason is that The base layer is uneven or the floor strips are deformed and bulged. The former is due to insufficient leveling of the keel surface during construction (usually the allowable error is less than 1mm), and the latter is due to insufficient ventilation. Small ventilation grooves should be made on the keel to prevent the bottom of the floor from Deformed due to humidity; ③ Partial warping, the main reason is that the floor joints are too small or there is no stretching space after the floor is damp, deformed and expanded

However, in practical application, if the moisture content is not up to the standard or the wood keel is moth-eaten, it will not only affect the quality of the floor and cause deformation, but also make the wood keel a breeding ground for mold and bacteria, spreading to wooden floors and other furniture , so that the life and health of consumers are affected
