Abstract
The invention relates to a locking catch block, which comprises a keel and a cushion block. The middle of the upper part of the keel is provided with a convex rib with a barb part and convex ribs distributed on two sides of the convex rib with the barb part, at least one inserting groove is formed on the keel, the cushion block consists of a main body part which has equal height with a keel cube and an inserting tenon matched with the inserting groove on the keel, and the inserting tenon on the cushion block is inserted in the inserting groove on the keel. In a fixer used with the locking catch block, one side of a block body is provided with a left groove, a right groove and a middle groove which are matched and sleeved with the left convex rib, the right convex rib and the middle convex rib of the keel respectively; and the left groove and the right groove are provided with flanges. The locking catch block can conveniently assemble a plurality of wood floor blocks together, the assembly is convenient and simple, and the wood floor is not easy to deform after assembling.
Description
Technical field
The present invention relates to the common joists technical field, more particularly relate to a kind of combined lock floor joist assembly and erecting tools that is suitable for floor and wallboard use.
Background technology
Traditional wood flooring is made up of plank piece and keel, match by the negative and positive groove between adjacent two planks, what keel adopted usually is lumps of wood bar, during use batten is followed closely on the ground, wood flooring is followed closely on lumps of wood bar again, and complexity so not only is installed, and is easy to destroy the structure in house, but also can make the stress of wood flooring excessive, cause the wood flooring distortion easily.
Number of patent application 200510019219.7, notification number CN1908341A disclose a kind of combined lock floor joist.Be illustrated in figure 1 as the structural representation that is connected between keel and plank, its keel B is snapped into plank A together.Keel B surface has the main muscle B1 of a buckle folding part and the symmetry analysis convex tendon B2 on main muscle B1 two limits, realize buckle among this main muscle B1 and convex tendon B2 sleeve matches respectively groove A1, the A2 on plank A, keel B can pin the seam between adjacent two blocks of plates, making between plate and the plate does not have the gap, and plate can not deform yet.Its weak point is:
1, keel B is along with the wood flooring user wishes wide as far as possible to the width of each plank cell block, generous proper demand seems, adopt junior unit type keel B to go to install and fix each plank cell block A, obviously can't reach and make wood flooring indeformable, firm requirement by mode as shown in Figure 2.
2, simultaneously present wood flooring also presents thin trend, and B goes to install and fix by mode as shown in Figure 2 with junior unit type locking catch block, can't guarantee that wood flooring is indeformable.
3, in installation process, because ground may be uneven, therefore the height of the keel of using is also indefinite, and this will use the keel of proper height.Keel need be fixed, use cutting element (as: electric saw) to prescind the part of keel then, so that the wood flooring of installing is more smooth.
Summary of the invention
The object of the present invention is to provide a kind of locking catch block, it can fit together a plurality of wooden floor blocks easily, and easy for installation simple, after the installation, wood flooring is not yielding.
Technology solution of the present invention is as follows:
Locking catch block, comprise keel 1, cushion block 2, have the convex tendon 11 of being with barb portion, the convex tendon 12 that is distributed in convex tendon 11 2 limits of band barb portion in the middle of the top of keel 1, form at least one inserting groove 13 on the keel 1, cushion block 2 is by constituting with contour main part 21 of keel 1 side's body and the grafting tenon 22 that matches with inserting groove 13 on the keel 1, and the grafting tenon 22 on the cushion block 2 is plugged in the inserting groove 13 on the keel 1.
The cross section of the convex tendon 11 of described band barb portion is " 7 " font, T-shape or " F " type.
The convex tendon 12 on described two limits is two sides of the convex tendon 11 that is symmetrically distributed in band barb portion.
Form screw fixed hole 14 on the described keel 1.
Described inserting groove 13 is that swallow-tail form, T type or circle lack shape, and corresponding grafting tenon 22 is that swallow-tail form, T type or circle lack shape.
Described inserting groove 13 is the dentation groove that is molded over the bottom of keel 1, and corresponding grafting tenon 22 is the dentation tenon.
Described inserting groove 13 is transverse splicing groove or vertical inserting groove.
Grafting tenon 22 on the described cushion block 2 exchanges with the inserting groove of keel 1 13.
Two grafting tenons 22 are arranged on the described cushion block 2.
With the matching used fixator of locking catch block, a side of block 3 has and left and right sides convex tendon 12, the middle convex tendon 11 of keel 1 match respectively left and right sides groove 32, the intermediate groove 31 of sleeve, and left and right sides groove 32 has rib 321.
Beneficial effect of the present invention is:
Need not use glue, nail and clamping plate when 1, installing, labor and material saving, and quick for installation, there is not noise, dust and the rubbish of installation.
2, can laterally vertically pin between adjacent two plates, and seamless between plate and the plate, plate can not be out of shape yet, warp, and has improved installation quality greatly.
3, owing to, be convenient to dismounting and maintenance without nail.
4, it is applicable to the floor of various materials, comprises consolidated floor, floor and curved, all kinds of composite floor board and multi-layer floor, wood flooring etc.
5, fixator can tighten up keel, so that prescind the part of keel with cutting element (as: electric saw).During use with the keel sleeve on fixator because left and right sides groove has rib, the keel of sleeve on fixator have certain distance with ground, exert all one's strength when being convenient to cut with instrument.
6, cushion block helps to load onto cushion block when plank unit broad or than Bao Shijia, prevents the wood flooring distortion, and it is more firm that wood flooring is installed.
