Abstract
The utility model provides a novel expansion joint structure, the expansion joint structure includes be located the inboard plywood that is difficult for the steel form in the construction one side and is located the expansion joint outside in expansion joint, be equipped with split bolt between plywood and the steel form. This expansion joint has good reliability, high, the effectual advantage of construction of efficiency of construction.
Description
Technical field
The utility model relates to building joint technique field, especially relates to a kind of novel telescopic crack structure.
Background technology
Along with the increase gradually of whole building size, be in considering Antiseismic building, crack resistance and construction costs, general by building via the measure such as aseismatic joint, shrinkage joint, be rationally divided into two and above element of construction, calculate respectively according to multiple high building during structural calculation.
In prior art, many templates of being served as structural joint side by warming plate, if application number is dam disclosed in the utility model of 200920251854.1, dam is provided with central-web and both sides wing plate, the cross section of central-web is M type, and both sides wing plate is arranged on the bottom of central-web, visible in conjunction with its Figure of description, not only fill warming plate in shrinkage joint, and the top of both sides wing plate also filling warming plate.The use of this cover plate strengthens the protection of warming plate and fixing, but there is following defect: its intensity of warming plate 1) due to different manufacturers or model is different, and do not propose to explicitly call for it in corresponding norm of construction and working measure, therefore after common construction due to the mould that rises, running pulp phenomenon that warming plate strength deficiency causes, shrinkage joint spacing after shaping does not meet structural requirement, more have and produce because vibrating head shakes the warming plate shifting phenomena caused, to such an extent as to it is in atmosphere exposed to build rear both sides reinforcing bar, has a strong impact on structural safety; 2) because warming plate size is little, in site operation, be difficult to the flatness requirement ensureing to put, commonly put the large phenomenon in Density inhomogeneity, space, build shaping after, surface of wall is uneven, cannot reach construction requirement; 3) when warming plate is built, under vibrating head effect, warming plate very easily enters in body of wall, serves as a body of wall part, causes body of wall effective thickness to reduce, so that twice gable anti-seismic performance slackens, even if also there is the situation of Lack of support under normal operating condition.The existence of above-mentioned factor, considerably increases the overall cost of difficulty of construction and engineering.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, disclose a kind of novel telescopic crack structure, this structure saves the conventional warming plate of prior art, the modular construction formed through split bolt by veneer and steel form not only ensure that construction effect, and improve efficiency of construction, the technical scheme adopted is: a kind of novel telescopic crack structure, it is characterized in that: described expanded joint structure comprises the steel form be positioned in the inboard not easily construction one side in shrinkage joint and the veneer be positioned at outside shrinkage joint, split bolt is provided with between described veneer and steel form.
Technical characteristic of the present utility model also has: there is release agent coating on described steel form surface.
Technical characteristic of the present utility model also has: described split bolt spacing is 400mm × 400mm.
Technical characteristic of the present utility model also has: the welded nut that described steel form does not contact with body of wall.
Technical characteristic of the present utility model also has: described nut spacing is 400mm × 400mm.
Technical characteristic of the present utility model also has: described veneer is wood glue plate and/bamboo slab rubber.
The beneficial effects of the utility model are: this shrinkage joint have employed the hybrid template form of factice plywood and steel form formation, be fixed by split bolt between two planks and reinforce, the operation of standardized module formula not only ensure that the planeness of construction, and accelerates speed of application and improve workmanship; Veneer to avoid in construction because the shrinkage joint constructional deficiency caused put by material, improves engineering planeness after completion, and avoids the inadequate problem of bearing capacity of wall body; Split bolt spacing set up the needs that entirely ensure that bonding strength.This shrinkage joint has good reliability, efficiency of construction is high, construction effect is good advantage.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is lateral views of accompanying drawing 1, and wherein, 1 is veneer, and 2 is steel forms, and 3 is split bolts, and 4 is nuts.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of novel telescopic crack structure, this expanded joint structure comprises the steel form 2 be positioned in the inboard not easily construction one side in shrinkage joint and the veneer 1 be positioned at outside shrinkage joint, and three links into an integrated entity by split bolt 3 successively after veneer, body of wall and steel form.Release agent is scribbled on the surface of steel form 2.The welded nut that steel form does not contact with body of wall.
The spacing of split bolt 3 can be set to 400mm × 400mm in the present embodiment.Nut 4 its spacing be welded on steel form 2 also can be 400mm × 400mm.
The optional veneer of the present embodiment is wood glue plate or bamboo slab rubber.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
