Abstract
Description
Technical Field
[0001] The utility model relates to the field of building structures, and particularly to a temperature-induced joint structure for an extra-long structure. Background Art
[0002] The temperature stress of an extra-long structure has always been a difficult problem in engineering. The traditional treatment method is to set temperature expansion joints at certain intervals, but this construction method has obvious defects: the risk of leakage at the existing joints is relatively large, and the later maintenance is difficult and costly.
[0003] In view of this, the inventor of the present case proposes a temperature-induced joint structure for an extra-long structure that can avoid the risk of water seepage and reduce the maintenance cost, and this case is thus generated. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a temperature-induced joint structure for an extra-long structure to solve the problem of water seepage at the joint and reduce the maintenance cost.
[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0006] The utility model provides a temperature-induced joint structure for an extra-long structure, which includes a U-shaped groove induced joint arranged at the stress-weak position of the extra-long structure. A water stop belt is buried at the bottom of the U-shaped groove induced joint, and a drainage structure is fixed on the outer side of the bottom of the U-shaped groove induced joint. The drainage structure is connected to the adjacent rainwater riser, and the U-shaped groove induced joint is filled with a caulking material.
[0007] Further, the drainage structure adopts an aluminum alloy drainage ditch.
[0008] Further, the aluminum alloy drainage ditch is fixed on the outer side of the bottom of the U-shaped groove induced joint through expansion bolts.
[0009] Further, the aluminum alloy drainage ditch includes a groove part and fixing parts on both sides thereof. The fixing parts are cooperated with galvanized flat steel pressing strips and fixed on the outer side of the bottom of the U-shaped groove induced joint through expansion bolts. The top of the groove part communicates with the bottom of the U-shaped groove induced joint, and the bottom of the groove part is communicated with the adjacent rainwater riser through a rainwater riser.
[0010] Further, the caulking material adopts asphalt mastic or polystyrene board.
[0011] After adopting the above technical solution, the construction method, working principle and beneficial effects of the temperature-induced joint structure for the extra-long structure of the utility model are as follows:
[0012] Construction method of the temperature-induced joint structure for the extra-long structure:
[0013] Step 1. According to the structural stress analysis, design temperature-induced joints at appropriate positions, and complete the civil engineering part of the temperature-induced joints of the U-shaped groove according to the construction drawings.
[0014] Step 2. After completing the above steps, fill the inside of the temperature-induced joints of the U-shaped groove with filling and caulking materials such as polystyrene boards or asphalt caulking.
[0015] Step 3. Fix the drainage structure on the outer side of the bottom of the temperature-induced joints of the U-shaped groove and connect it to the adjacent rainwater riser. Specifically, for example, use expansion bolts to fix the aluminum alloy drainage ditch on the outer side of the bottom of the temperature-induced joints of the U-shaped groove and connect it to the adjacent rainwater riser.
[0016] The induced joint of the present utility model is a construction method for generally weakening the cross-section of components. By setting temperature-induced joints in the super-long structure and adopting the method of orderly releasing harmful stresses and reasonable diversion device measures, certain control is carried out on the disordered cracks generated in the concrete structure under conditions such as seasonal temperature difference and self-shrinkage, which is beneficial to the waterproof and seepage prevention of the super-long structure. Through the diversion device, a small amount of accumulated water at the preset induced joint is drained into the rainwater riser, reducing the later maintenance cost.
[0017] Specific advantages include:
[0018] 1. The super-long structure can be set without conventional temperature expansion joints, solving the problem that setting expansion joints in the super-long structure affects the building facade effect.
[0019] 2. The construction method of the temperature-induced joints of the super-long structure does not affect the layout of the structural column grid.
[0020] 3. By artificially setting weak structural parts in the temperature-induced joints of the super-long structure, the structure is guided to crack at the temperature-induced joints under the action of temperature, reducing the extensive and complicated inspection work for leakage points after later operation.
[0021] 4. For the temperature-induced joints of the super-long structure, a drainage structure is pre-made on the outer side of the bottom of the U-shaped induced joint groove, and organized drainage measures are taken to solve the problem of great difficulty in high-altitude maintenance in the later stage.
[0022] 5. The temperature-induced joints of the super-long structure have little influence on the normal use of the floor and roof, and the surface of the floor and roof is flat without protruding structures. Description of the Drawings

[0027] As shown in Figure 1 , a temperature-induced joint structure for an ultra-long structure disclosed in an embodiment of the present utility model includes a U-shaped groove-induced joint 1 provided at a stress-weak position of the ultra-long structure.

The fixing portions 32 cooperate with a galvanized flat steel pressing strip 5 and are fixed outside the bottom of the U-shaped groove-induced joint 1 by expansion bolts 4. The top of the groove portion 31 communicates with the bottom of the U-shaped groove-induced joint 1, and the bottom of the groove portion 31 is connected to an adjacent rainwater riser through a rainwater riser 6.
[0030] As a preferred embodiment, the caulking material 7 adopts asphalt ointment or polystyrene board. The asphalt waterproof ointment is mainly used for joint waterproofing, and the polystyrene board can be used as a protective layer or insulation layer for the waterproof layer.

Specifically, for example, use expansion bolts 4 to fix the aluminum alloy drainage ditch 3 outside the bottom of the U-shaped groove-induced joint 1 and connect it to an adjacent rainwater riser.
[0035] The induced joint of the present utility model is a construction method for generally weakening the cross-section of a member. The U-shaped groove induced joint 1 is provided in the super-long structure. By means of orderly releasing harmful stresses and a drainage structure as a reasonable diversion device measure, it controls the disordered cracks generated in the concrete structure under conditions such as seasonal temperature difference and self-shrinkage, which is beneficial to the waterproof and seepage prevention of the super-long structure. Through the drainage structure, a small amount of accumulated water at the preset U-shaped groove induced joint 1 is drained into the rainwater riser, reducing the later maintenance cost.
