Description
Technical field
The utility model relates to public and track technical field of construction civilian construction, particularly a kind of basement attaching track structure.
Background technology
Raising along with the architectural design level; The track mouth that leads to basement is tending towards rationally art up, meets outside the wagon flow requirement of transport hub in the outlet of basement parking garage and the inlet of town road during design, dexterously the track is arranged on the recessed angle position on the annex plane of highrise building; They adhere to the outside of basement periphery exterior wall mostly; Utilize outer wall of basement as one side, track side wall, arrange little, the both artistic and practical effect of floor space to obtain the track.But the negative one deck of basement is dark more, and sloping track length is just long more, and the horizontal length size of adhering to the outer wall of basement scope is just big more, and difficulty of construction is also just big more.
Traditional job practices is that outer wall of basement and track structure are separated construction; After promptly the waterproofing course and topping in the outer wall of basement and the outside thereof accomplished in construction earlier; Backfill foundation ditch periphery soil is constructed to track base plate and bed course, track external wall and waterproofing course thereof and topping again.This method principle is simple, and constructing operation is also comparatively simple, but its construction period is quite long, influences programming easily.In addition, when used in the track of adopting this job practices to form, have open defect: constuction joint was left in the junction of (1) outer wall of basement and track base plate, after the long-time use in track, the phenomenon of track bottom slab crack can occur; (2) during the backfill foundation ditch; The compactness of pit backfill soil is difficult to reach standard at short notice, so after completion of works uses, because pit backfill soil is long-time heavy real; The waterproofing course of track floor below and topping can separate even drawing crack, the final phenomenon such as leak that produces; (3) the too early backfill foundation ditch of this job practices can make basement occur overall buoyancy too early, influences workmanship.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of constitutionally stable basement attaching track structure is provided.
The technical scheme of the utility model is: a kind of basement attaching track structure comprises the track base plate that sets gradually, anti-sticking waterproof roll, mortar waterproof matrix and track bottom board concrete bed course from top to bottom; Base plate both sides, track are provided with outer wall of basement and track external wall respectively; Track base plate, outer wall of basement and track external wall are integral structure; Mortar waterproof matrix and anti-sticking waterproof roll are respectively the monolithic construction of two lateral bucklings; The horizontal segment of anti-sticking waterproof roll is closely attached on base plate bottom surface, track; Anti-vertical section of gluing waterproof roll that is positioned at both sides is closely attached on outer wall of basement and track external wall respectively, and the horizontal segment of mortar waterproof matrix is closely attached on the horizontal segment bottom surface of anti-sticking waterproof roll, and the vertical section correspondence that is positioned at the mortar waterproof matrix of both sides is closely attached on vertical section of anti-sticking waterproof roll; The horizontal segment below of mortar waterproof matrix sets gradually track bottom board concrete bed course and track base plate foundation soil, and the vertical section outside that is positioned at the mortar waterproof matrix of both sides sets gradually fish tail and waterproof layer, soldier pile and water-stop curtain.
The inboard of said track external wall is provided with inboard formwork gripper shoe, between inboard formwork gripper shoe, track external wall, anti-sticking waterproof roll, mortar waterproof matrix and the fish tail and waterproof layer through to drawing screw to be fixedly connected;

(5) reinforcing bar and the inboard formwork gripper shoe of outer wall of basement and track external wall are installed respectively, the reinforcing bar of track base plate is installed simultaneously, concreting makes track base plate, outer wall of basement and track external wall be integrally formed the formula structure then; Should note during concreting; Build outer wall of basement to track base earlier; Carry out the concreting of track base plate after letting concrete sink calmly at interval in 2 hours again; Carry out the above outer wall of basement of track base plate face and the concreting of track external wall after the concrete of same 2 hours passing bay base plates at interval sinks and decides again, carry out maintenance by the standard time at last.
In the step (5); When the reinforcing bar of installation outer wall of basement and track external wall and inboard formwork gripper shoe; Employing is fixedly connected with anti-sticking waterproof roll, mortar waterproof matrix inboard formwork gripper shoe drawing screw with fish tail and waterproof layer; Concreting in the space that between formwork gripper shoe and anti-sticking waterproof roll, forms then forms outer wall of basement and track external wall.
In the step (5), as shown in Figure 2, to carry out before the concreting, the junction of track base plate and track external wall is preset with stirrup reinforcing bar 14.When the inboard formwork gripper shoe of base plate two side, track wall is installed since the concrete of track base plate do not build as yet; The available split heads reinforcing bar 14 of shoring of inboard formwork gripper shoe perpendicular positioning is accomplished; Split heads muscle lower end is placed on track base plate bottom layer of the reinforcing steel face; Inboard formwork gripper shoe is supported in the upper end, cuts off in recessed 3cm position, concrete surface in the extending part after construction is accomplished, and does antirust processing after the completion.
In the step (1), the soldier pile and the pre-buried degree of depth of water-stop curtain that are positioned at the outer wall of basement outside are the height from pattern foundation pit supporting structure lowermost end (comprising embedded depth) to negative track, one deck entrance base; The pre-buried degree of depth of soldier pile and water-stop curtain that is positioned at the track external wall outside is greater than the degree of depth of the set position of bottom board concrete bed course, track.
In the step (2), fish tail and waterproof layer is directly to construct on the soldier pile face in the concrete foundation ditch, and track bottom board concrete bed course is to adopt concrete on the base plate foundation soil of the track of compacting, to construct.
In the step (3), the plaster of mortar waterproof matrix carries out on fish tail and waterproof layer and track bottom board concrete bed course respectively simultaneously.
In order better to lay the continuous anti-sticking waterproof roll that overlays, in the said step (3), the mortar waterproof matrix is criticized into the arc chord angle of R=50~80mm respectively at inner corner trim and external corner place.
In the step (4), the construction of anti-sticking waterproof roll respectively the horizontal segment of mortar waterproof matrix with vertically carry out simultaneously on the section, note lap length during construction, on the corner space and hollowing phenomenon do not appear in continuous laying.
This basement attaching track structure and job practices thereof; Its principle is: adopt with the opposite contrary sequence method of tradition the track structure is constructed; Each layer structure that as far as possible keeps track horizontal direction and vertical direction is integral structure; Reduce the existence in slit, thereby make that the overall structure in track is more firm.
As stated, can realize preferably that just the utility model, the foregoing description are merely the preferred embodiment of the utility model, be not the practical range that is used for limiting the utility model; Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
