Abstract
The utility model relates to a combined keel for a floor. The combined keel consists of a lower-layer keel, a left-upper-layer keel and a right-upper-layer keel, wherein a 7-shaped middle main rib, a left auxiliary rib and a right auxiliary rib are formed on a square block structurally; a middle main rib slot and a left auxiliary rib slot are formed in the left-upper-layer keel, wherein the middle main rib slot is formed in the main rib slot, the left auxiliary rib is inserted and sleeved into the left auxiliary rib slot, and a keel main rib and a keel left auxiliary rib are formed on the upper part of the left-upper-layer keel; a keel right auxiliary rib and a right auxiliary rib slot are formed on the right-upper layer keel, wherein the left auxiliary rib is inserted and sleeved into the right auxiliary rib slot; and a gap is reserved between the left-upper-layer keel and the right-upper-layer keel. The combined keel disclosed by the utility model can be used for effectively preventing the wooden floor from arching and deforming, reducing the production cost of the keel, conveniently adjusting the height of the keel and providing convenience for wiring or water circulation in the keel.
Description
Technical field:
The utility model relates to technical field of floor, more specifically to a kind of floor combined joist.
Background technology:
Current floor mostly is integral spine with keel, and its weak point is: if 1, integral spine all uses metal material to manufacture, then the cost of production of keel is higher.2, process cabling or walk aquaporin and be not easy in the integral spine, processing is got up also inconvenient.3, the height of integral spine is difficult for regulating.4, integral spine prevents that floor arch camber deformation effect is poor.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of floor combined joist is provided, it can effectively prevent wood flooring arch camber distortion, can reduce the cost of production of keel simultaneously, make things convenient for the adjustment keel height, convenient in keel cabling or leak water.
Technology solution of the present utility model is as follows:
A kind of floor combined joist, it is comprised of lower floor's keel and upper strata keel, and the structure of lower floor's keel is for forming the main muscle in centre, the auxiliary muscle of the auxiliary muscle in the left side and the right of " 7 " font at square block;
The upper strata keel are the hollow body that metal material is manufactured, the bottom of upper strata keel forms the disconnection breach, main muscle slot, the auxiliary muscle slot of the auxiliary muscle slot in the left side and the right in the middle of the bottom of upper strata keel forms, middle main muscle, the auxiliary muscle of the auxiliary muscle in the left side and the right respectively sleeve form keel master muscle, keel inside left muscle and keel inside right forward muscle on the keel of upper strata in the main muscle slot in centre, the auxiliary muscle slot of the auxiliary muscle slot in the left side and the right;
Leave right lateral clearance between the auxiliary muscle slot in the right and the auxiliary muscle in the right.
Described keel master muscle is " ten " font, " T " font or " 7 " font, and keel inside left muscle and keel inside right forward muscle are " 1 " font.
Leave lateral clearance between the auxiliary muscle slot in the described left side and the auxiliary muscle in the left side.
The auxiliary muscle of the auxiliary muscle in the described left side and the right is " 1 " font, and middle main muscle is " T " font.
The beneficial effects of the utility model are:
It can effectively prevent wood flooring arch camber distortion, can reduce the cost of production of keel simultaneously, makes things convenient for the adjustment keel height, convenient in keel cabling or leak water.

Among the figure: 1, lower floor's keel; 11, square block; 12, middle main muscle; 13, the auxiliary muscle in the left side; 14, the auxiliary muscle in the right; 2, upper strata keel; 21, middle main muscle slot; 22, the auxiliary muscle slot in the left side; 23, the auxiliary muscle slot in the right; 2a, keel master muscle; 2b, keel inside left muscle; 2c, keel inside right forward muscle; 2d, disconnection breach; 14-23, right lateral clearance; 13-22, left lateral clearance.
The specific embodiment:
Embodiment 1: sees shown in Fig. 1,2, and a kind of floor combined joist, it is comprised of lower floor's keel 1 and upper strata keel 2, and the structure of lower floor's keel 1 is for forming the main muscle 12 in centre, the auxiliary muscle 14 of the auxiliary muscle 13 in the left side and the right of " 7 " font at square block 11;
The hollow body that upper strata keel 2 are manufactured for metal material, the bottom of upper strata keel 2 forms and disconnects breach 2d, main muscle slot 21, the auxiliary muscle slot 23 of the auxiliary muscle slot 22 in the left side and the right in the middle of the bottom of upper strata keel 2 forms, the auxiliary muscle 14 in middle main muscle 12, the auxiliary muscle 13 in the left side and the right respectively sleeve forms keel master muscle 2a, keel inside left muscle 2b and keel inside right forward muscle 2c on the upper strata keel 2 in the main muscle slot 21 in centre, the auxiliary muscle slot 23 of the auxiliary muscle slot 22 in the left side and the right;
Leave right lateral clearance 14-23 between the auxiliary muscle slot 23 in the right and the auxiliary muscle 14 in the right.
Described keel master muscle 2a is " ten " font, and keel inside left muscle 2b and keel inside right forward muscle 2c are " 1 " font.
Embodiment 4, as shown in Figure 6, leave left lateral clearance 13-22 between the auxiliary muscle 13 of the auxiliary muscle slot 22 in the described left side and the left side.All the other are with embodiment 1.
Embodiment 5, and as shown in Figure 7, the auxiliary muscle 14 in the auxiliary muscle 13 in the described left side and the right is " 1 " font, and middle main muscle 12 is " T " font.All the other are with embodiment 1.
Embodiment 6, and as shown in Figure 8, the auxiliary muscle 14 in the auxiliary muscle 13 in the described left side and the right is " T " font, and middle main muscle 12 is " T " font.All the other are with embodiment 1.
Operating principle: the utility model is fitted together by lower floor's keel 1 and upper strata keel 2 and consists of floor keel, thus process cabling on lower floor's keel 1 or walk aquaporin easier.Simultaneously, upper strata keel 2 can be manufactured with metal, and lower floor's keel 1 can adopt wood materials to manufacture, can save like this cost of manufacturing of keel, simultaneously when dispatching from the factory, lower floor's keel 1 can adopt differing heights, can regulate with the height of lower floor's keel 1 height of one-piece keel like this, thereby play the effect of adjustment keel height.
The utility model is more topmost to be, leaves right lateral clearance 14-23 between the auxiliary muscle 14 of the auxiliary muscle slot 23 in the right and the right.Like this when plank piece bulking is out of shape, the compressive stress between two adjacent plank pieces has been eliminated by right lateral clearance 14-23, thereby plays the effect that prevents plank piece arch camber distortion.
