Abstract

The utility model discloses a keel for building support. The keel is in a column shape and comprises a casing and an inner core, wherein the casing is sheathed outside the inner core, the casing is made of composite materials, engineering plastics, resin materials or rubber, the inner core is made of metal materials, and notches are arranged on the outer wall column surface of the casing. The keel provided by the utility model has the advantages that the materials are stable, the contraction and the deformation cannot occur even in the humid environment, the corrosion resistance and the repeated use are realized, the energy is saved, the environment is protected, meanwhile, the hardness is improved, the bearing capability of the keel is enlarged, the fracture cannot easily occur, in addition, the casing of the keel is made of materials capable of being easily nailed by nails, and the construction is convenient.

Description

Keel

Technical field

The utility model relates to a kind of backing material for building, particularly a kind of keel.

Background technology

Keel are a kind of materials commonly used in the finishing, and Multiple Type is arranged, and mainly play a supportive role.The skeleton of furred ceiling, platform, vertical partition wall, in addition some moulding is all built with keel.The kind of keel is a lot, according to the difference of material, can be divided into rough ground, steel keel etc.

The advantage of rough ground is to do the moulding of any complexity, to be connected coefficient of deformation less with woodwork, still, rough ground make moist easily distortion, perishable, hardness is little, the erosion easy fracture that weight capacity is poor, be subjected to termite, safety factor is lower, and simultaneously, the forest reserves of China are very in short supply, use traditional rough ground need to expend a large amount of timber, and rough ground can not use by secondary, therefore uses rough ground not only to waste a large amount of forest reserves, also not environmental protection.

The steel keel have greatly reduced the waste of timber, the speed of building is fast, and can reuse, energy-conserving and environment-protective, reduced cost, simultaneously nonflammable, be not subjected to moisture effect, be subjected to the house vibration influence little, solved the problem that some rough grounds cann't be solved, but adopt the steel keel also to exist problem: the workman can't be fixed to template on the keel by nail when installation form, and this is a technical barrier.

The utility model content

According to an aspect of the present utility model, provide a kind of hardness large, be easy to fix, the keel of reusable, energy-conserving and environment-protective.

These keel are cylindricality, comprise housing and inner core, and housing is sheathed on outside the inner core, and its middle shell adopts composite material, engineering plastics, resin material or rubber to make, and inner core is that metal material is made.Housing adopts to be convenient to the material that nail hammers into and to make, conveniently template is fixed on the keel, constructability, while materials stable material quality is not even shrink indeformable, corrosion-resistant under the environment of humidity yet, reusable, energy-conserving and environment-protective, simultaneously, inner core has increased the hardness of keel, strengthened the ability to bear of keel, not easy fracture.

In some embodiments, inner core is hollow steel pipe.Hollow steel pipe has alleviated the weight of keel when guaranteeing keel hardness, reduced workman's difficulty of construction.

In some embodiments, housing outer wall cylinder is offered notch.The keel external surface is offered the frictional force that notch has increased external surface, holds easily, is difficult for landing, is convenient to install and use safety.

In some embodiments, inner walls and interior outer core close proximity, wherein inner walls is offered a plurality of filling slots along its length, filling adhesive in the filling slot.Housing and inner core are combined closely, and preventing that inner core from sliding out with housing separates, and causes unexpected injury.

Description of drawings

Fig. 1 is the structural scheme of mechanism of the keel of the utility model one embodiment;

Fig. 2 is that keel shown in Figure 1 are along the sectional view of A-A direction.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1, Fig. 2 have schematically shown the keel according to a kind of embodiment of the present utility model.

Shown in Figure 2 such as Fig. 1, this keel bone comprises housing 1 and inner core 2 as rectangular cylinder.In one embodiment, housing 1 is made for composite material, and the other materials that its housing 1 also can adopt engineering plastics, resin material or rubber etc. to make things convenient for nail to hammer into is made.Inner core 2 is a hollow steel pipe.Housing 1 is sheathed on the outside of inner core 2.The housing that composite material is made is convenient to nail and is hammered into, convenient module is fixed on the keel, constructability, simultaneously, composite material quality is stable, even under the environment of humidity, do not shrink yet indeformable, corrosion-resistant, reusable, energy-conserving and environment-protective.In addition, utilize hollow steel pipe as inner core 2, without having guaranteed that keel have larger hardness, strengthened the ability to bear of keel, frangibility not, the deadweight that has alleviated simultaneously keel has reduced workman's difficulty of construction.

Offer along its length notch 3 on two areas of housing 1 external surface face less than normal, and every one side has the parallel notch of twice 3.Offering notch 3 has not only increased the frictional force of keel external surfaces, is convenient to hold, and is difficult for landing, be convenient to install and use safety, avoid causing unnecessary injury, simultaneously, with these keel when be used for laying wooden floor, can reduce the contact area with the floor, be convenient to ventilative, " breathings " on floor, and flooring nail hammers into the notch position, so that in the head of a nail embedding notch, keep the smooth of keel surface, make floor covering layers more attractive in appearance.

Housing 1 inwall internal diameter is suitable with inner core 2 outer wall external diameters, makes housing and inner core close proximity.Wherein, housing 1 inwall is offered four filling slots 4 along its length, at filling slot 4 interior filling adhesives.Housing and inner core are combined closely, bond together firmly, preventing that inner core from sliding out with housing separates, and causes unexpected injury.

Keel of the present utility model, adopt composite material, engineering plastics or rubber to replace flitch, reduced the felling to trees, energy-conserving and environment-protective, solved the distortion of Traditional Wood keel moisture-sensitive, problem that hardness is little, solved simultaneously the steel keel and template can't be fixed to technical barrier on the keel by nail.

Above-described only is embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
