Abstract
The utility model discloses a self tapping screw reinforcing wood structure bolt node, including timber compoment, self tapping screw and bolt hole, be provided with the bolt hole on the timber compoment, self tapping screw perpendicular to bolt hole and timber compoment's wood grain direction changes over to wood structure bolt node, self tapping screw be full-thread self tapping screw. The utility model discloses not influencing under the prerequisite that the timber structure is pleasing to the eye, does not increase the dead weight, through the utility model discloses bolt joint after the reinforcing has also increased the ductility of component when improving bearing capacity.
Description
Technical field
The utility model relates to the enhancing structure of building wooden construction bolt joint, relates in particular tapping screw and strengthens wooden construction bolt joint.
Background technology
Timber is a kind of natural and have the material of affinity, is considered to the first-selected building materials of " green building ", and modern wood structure is the structural shape of a kind of " energy-conservation, economize ground, ecological, environmental protective ".
The joint behavior of wooden construction directly affects structural strength, application life and reliability, and meanwhile, timber has the shortcomings such as low, the easy splitting of tensile strength, the variation of intensity moisture content, therefore, is the important step of timber buildings Planting Techniques to the enhancing of node.
Wooden construction bolt joint is due to the characteristic of the easy splitting of timber at present, and node ultimate bearing capacity is not in full use, and easily produces brittle fracture.Existing node enhancement method, as metal sheet strengthens, FRP strengthens etc., exists to involve great expense, trivial operations, affect the unfavorable factors such as outward appearance, is not suitable for the building theory of current green building, low-carbon energy-saving.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of high-strength efficient, construct convenient, not increase member deadweight and volume, widely applicable tapping screw to strengthen wooden construction bolt joint, its maximum feature is not affect the appearance, do not increasing under the prerequisite of member dead weight and volume, makes it improve the requirement of member ultimate bearing capacity, ductility.
The technical solution adopted in the utility model: a kind of tapping screw strengthens wooden construction bolt joint, comprise timber compoment, tapping screw and bolt hole, on described timber compoment, be provided with bolt hole, described tapping screw proceeds in wooden construction bolt joint perpendicular to the grain direction of bolt hole and timber compoment, and described tapping screw is full thread tapping screw.
As preferably, the screw diameter of described tapping screw should be controlled at 3~6mm, and between tapping screw, spacing must not be less than 5 times of tapping screw screw diameters.
As preferably, the position that described tapping screw proceeds to and the clear spacing of bolt hole must not be greater than the diameter of bolt, and are arranged in the pressure-bearing side of bolt hole, or bilateral is all arranged.
As preferably, described tapping screw and the clear spacing of bolt hole equal zero, its humidification of performance that can be best.
As preferably, described tapping screw length equals timber compoment and squeezes into the height in direction at tapping screw.
The utility model is by proceed to tapping screw in timber, because the snap-in force effect of screw thread makes the grain of wood be not easy to tear, thus raising bearing capacity and the ductility of member.
Beneficial effect: the utility model wooden construction bolt joint, by the enhancing of tapping screw, can effectively improve ductility and the intensity of node, for applying of Green High Performance wooden construction established good basis.This type of timber structural system have bearing capacity high, process and construct convenient, outward appearance is graceful and without advantages such as decorations; Meanwhile, this type of timber structural system can be accomplished large-scale industrialized processing, on-the-spot quick-assembling, and overall structure is lower from heavy and light, transportation and basic expense, has greatly widened the range of application of wooden construction.
Accompanying drawing explanation
Fig. 1 is full thread tapping screw schematic diagram of the present utility model;
Fig. 2 is that tapping screw of the present utility model strengthens wooden construction bolt joint schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 2, on timber compoment 1, be provided with bolt hole 3, the position proceeding at the pressure-bearing side upper end of wooden construction bolt joint bolt hole 3 mark tapping screw 2, the clear spacing of this position and bolt hole 3, the diameter of tapping screw 2 arrange according to node size, the diameter of bolt, mechanical structure and the load type of bearing.
Pass through comparative experimental research, the clear spacing of the position that tapping screw 2 proceeds to and bolt hole 3 must not be greater than the diameter of bolt and desirable clear spacing equals zero, the screw diameter of tapping screw 2 should be controlled at 3~6mm, between tapping screw, spacing must not be less than 5 times of tapping screw screw diameters, as shown in Figure 1, tapping screw 2 is full thread tapping screw, in Specific construction process, should strictly control above-mentioned parameter, prevents that node from damaging even destruction in advance.
The position that described tapping screw 2 proceeds to, should be arranged in bolt joint hole pressure-bearing side for the node that bears dull load, for the node that bears cyclic reverse loading, should all arrange at the bilateral of bolt hole, and other parameter is with dull load node.
In the position of mark, before tapping screw proceeds to, to polish clean and keep this surfacing, while proceeding to tapping screw, need keep, vertical with grain direction vertical with the antarafacial of bolt, can not there is the crooked situation about proceeding to of tapping screw.
It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
